Please refer to <FIG>, the first embodiment provides a sliding puzzle toy <NUM>, which includes a main body <NUM> and a plurality of sliders <NUM> that can be slidably connected to the main body <NUM>. In this embodiment, the main body <NUM> is roughly arranged in a square shape, including two bottom walls 10a and a side wall 10b connected between the two bottom walls 10a. It can be understood that since the main body <NUM> is roughly arranged in a square shape, the two bottom walls 10a are correspondingly arranged as squares, and the side walls 10b include four closed connected planes <NUM>, wherein each two adjacent planes <NUM> are connected with an arc-shaped transition surface <NUM> to enable the sliders <NUM> to move more smoothly on the side walls 10b. It should be noted that the side length of bottom wall 10a is equal to the sum of the side length of side wall 10b and the thickness of two sliders <NUM>. so as to make the outer surface of the sliding puzzle toy <NUM> smooth and tidy when the slider <NUM> is connected to the main body <NUM>, making it easy to play.

In other embodiments of present disclosure, the main body <NUM> can also be arranged in other cylindrical structures, such as a cylinder (a sliding puzzle toy provided by the second embodiment as shown in <FIG>), a triangular prism, or other multi prism structures. When the main body <NUM> is arranged in a cylinder, the bottom wall 10a is circular, and the side wall 10b is a closed curved surface; When the main body <NUM> is arranged in a triangular prism or other multi prism structure, the bottom wall 10a is a triangle or other polygon, and the side wall 10b includes three or a corresponding number of planes <NUM>. Similarly, there is an arc-shaped transition surface <NUM> connected between every two adjacent planes <NUM>. When the main body <NUM> is arranged in other columnar structures, the length or diameter of the bottom wall 10a and the side wall 10b should be adjusted adaptively based on the principle of making the outer surface of the sliding puzzle toy <NUM> smooth and tidy.

In the first embodiment, one of the bottom walls 10a is provided with a recessed slot <NUM> and a separable block <NUM>. One side of the recessed slot <NUM> is connected to the side wall 10b to enable the recessed slot <NUM> to serve as a slider gap, and the connection between the recessed slot <NUM> and the side wall 10b has an arc-shaped transition to enable sliders <NUM> to move more smoothly between the recessed slot <NUM> and the side wall 10b. In other embodiments of present disclosure, it is not limited to setting recessed slots <NUM> and separable blocks <NUM> on only one bottom wall 10a, but can also set recessed slots <NUM> and separable blocks <NUM> on both bottom walls 10a simultaneously. The number of recessed slots <NUM> and separable blocks <NUM> on each bottom wall 10a can also be two, three, or more.

In the first embodiment, two connection slots <NUM> and two positioning slots <NUM> are also recessed inside the recessed slot <NUM>. The two connection slots <NUM> are located on opposite sides of the walls inside the recessed slot <NUM>, which are detachably connected to the part of the separable block <NUM>. The two positioning slots <NUM> are located on the bottom wall of recessed slot <NUM> and are adjacent to one connection slot <NUM>, respectively, which are detachably connected to another part of the separable block <NUM>. In other embodiments of present disclosure, the recessed slot <NUM> may not be equipped with a connection slot <NUM> and/or a positioning slot <NUM>.

In the first embodiment, the separable block <NUM> is matched with the recessed slot <NUM>, and one side of the separable block <NUM> is detachably connected to the open side of the recessed slot <NUM>. The other side of the separable block <NUM> is pivoted to the side wall of the recessed slot <NUM> through the connection strip <NUM>. Wherein the connection strip <NUM> is accommodated and connected between the separable block <NUM> and the bottom wall 10a, and the two ends of the connection strip <NUM> are respectively pivoted with the separable block <NUM> and the bottom wall 10a. The setting of the connection strip <NUM> allows the separable block <NUM> to have a high degree of rotational freedom relative to the bottom wall 10a. It can be understood that the separable block <NUM> and the recessed slot <NUM>, which are pivoted and matched on the bottom wall 10a, can open or close the slider gap during the relative rotation of the separable block <NUM>, allowing the slider <NUM> to move on the main body <NUM> to ensure the game can proceed, and can close the slider gap when idle to prevent dust and maintain the overall aesthetics of the sliding puzzle toy <NUM>. In other embodiments of present disclosure, the separable block <NUM> can also be directly pivoted with the side wall of the recessed slot <NUM>. Obviously, in other embodiments, the separable block <NUM> matches with the recessed slot <NUM> can also be directly and detachably connected to the recessed slot <NUM>. When in use, the slider gap can be opened or closed by placing the separable block <NUM> in the recessed slot <NUM> or disassembling and separating the separable block <NUM> from the recessed slot <NUM>.

In the first embodiment, the two side walls opposite each other of the separable block <NUM> are respectively provided with one snap bulge <NUM> and one snap block <NUM>, wherein the snap bulge is arranged corresponding to the connection slot <NUM> and is detachably connected to the connection slot <NUM>, which is used to enable the separable block <NUM> to be stably connected to the recessed slot <NUM> when the sliding puzzle toy <NUM> is idle, preventing the separable block <NUM> from detaching from the recessed slot <NUM> under gravity. The snap block <NUM> is located on the side facing the positioning slot <NUM> on the side wall of the separable block <NUM>. The snap block <NUM> is matched with the positioning slot <NUM> and is detachably connected to the positioning slot <NUM>, playing a role in positioning and fixing the separable block <NUM> and the recessed slot <NUM> in collaboration with the snap bulge <NUM> and the connection slot <NUM>. In other embodiments of present disclosure, when there is no connection slot <NUM> and/or positioning slot <NUM> in the recessed slot <NUM>, the separable block <NUM> is also not provided with a snap bulge <NUM> and/or a snap block <NUM>.

It should be noted that the structural design of setting the recessed slot <NUM> and separable block <NUM> on the bottom wall 10a has the advantage of a more streamlined and compact connection structure between the separable block <NUM> and the bottom wall 10a compared to the structure of setting the separable puzzle unit blocks on the side wall in existing technology, which is beneficial for reducing production costs and improving assembly efficiency. Moreover, setting the recessed slot <NUM> and the separable block <NUM> on the bottom wall 10a not only facilitates the operation of flipping the separable block <NUM>, but also enables the slider <NUM> to move on the side wall 10b without being limited by the pattern of the separable block <NUM>.

The outer surface of the side wall 10b is provided with a plurality of the sliding grooves which are intersected with each other along the circumferential and longitudinal directions, and the sliding groove is movably connected with a part structure of slider <NUM>. In the first embodiment, the sliding groove includes three circumferential sliding grooves <NUM> and twelve longitudinal sliding grooves <NUM>, wherein one longitudinal sliding groove <NUM> passes through the connection between the recessed slot <NUM> and the side wall 10b and extends towards the bottom wall of the recessed slot <NUM> to enable the slider <NUM> to enter and exit the recessed slot <NUM> under the guidance of the longitudinal sliding groove <NUM>. In other embodiments of present disclosure, the number of circumferential sliding grooves <NUM> and longitudinal sliding grooves <NUM> can be adaptively adjusted according to the number and arrangement of sliders <NUM>.

Each slider <NUM> includes a plate <NUM> and a base pillar <NUM> arranged in a vertical direction, wherein the plate <NUM> is exposed on the side wall 10b and matched with the side wall 10b, that is, when the side wall 10b is a closed curved surface, the plate <NUM> is an arc-shaped plate; when the side wall 10b is connected by multiple closed planes, the plate <NUM> is a flat plate. A pattern can be set on the plate <NUM> through spraying, adhesive connection, snap-fit connection, buckle connection, threaded connection, bolt connection, or magnetic connection. The patterns of several plates <NUM> can be spliced to form a complete large pattern, and the game can be played by restoring the disrupted patterns of several plates <NUM>.

The base pillar <NUM> passes through the sliding groove to movably connect the slider <NUM> within the sliding groove. In the first embodiment, a positioning piece <NUM> is slidably sleeved on the base pillar <NUM>, and the positioning piece <NUM> is movably connected in the sliding groove along with the base pillar <NUM> and contacts with the inner wall of the sliding groove. There is an elastic member <NUM> (such as a spring, etc.) connected between the positioning piece <NUM> and the end of the base pillar <NUM>, which is used for providing an extra space for slider <NUM> to move smoothly on the main body <NUM> when the slider <NUM> crosses the connection between the recessed slot <NUM> and the side wall 10b and when the slider <NUM> crosses any arc-shaped transition surface <NUM>, ensuring that the sliding puzzle toy <NUM> has a good gaming feel. In the other embodiments, the slider <NUM> can also adopt other structures to achieve the purpose of being movable and connected within the sliding groove, for example, a magnet may be provided fixed at the end of the base pillar <NUM> in each slider <NUM>, and the magnet is movably connected in the sliding groove along with the base pillar <NUM>. At this time, a magnetic film is set on the outer side on the side wall 10b opposite to the magnet, and the magnetic film is magnetically connected to the magnet to slidably connect the slider <NUM> to the main body <NUM>.

During the game, the separable block <NUM> is rotated to open the recessed slot <NUM>. By manually pushing the plate <NUM>, the base pillar <NUM> is driven to move between the circumferential sliding grooves <NUM> and the longitudinal sliding grooves <NUM> which are intersected with each other, in order to change the relative position of any slider <NUM> on the side wall 10b, until the disrupted large pattern is restored to end the game.

Please refer to <FIG>, a sliding puzzle toy <NUM> of the third embodiment of the present disclosure is provided, which differs from the first embodiment in that the separable block <NUM> can be slidably connected within the recessed slot <NUM>. In the third embodiment, the length of the separable block <NUM> is equal to the length of the recessed slot <NUM>. At this time, the other side of the recessed slot <NUM> is connected to the outside, making the recessed slot <NUM> a straight structure with both ends intercommunicated. By pushing the separable block <NUM> forward or backward, the recessed slot <NUM> can be opened or closed. Moreover, the other side of the recessed slot <NUM> can also be intercommunicated to the side wall 10b at the same time. By pushing the separable block <NUM> forward or backward, the recessed slot <NUM> can be can opened to increase the utilization convenience of the sliding puzzle toy. In other embodiments of the present disclosure, the other side of the recessed slot <NUM> can also be set only to be connected to the outside.

In order to ensure that the separable block <NUM> is securely slidably connected within the recessed slot <NUM>, a guide slot <NUM> is provided on the side wall of the recessed slot <NUM> along the movement direction of the separable block <NUM>. The separable block <NUM> is provided with a first sliding plate <NUM> on the side wall opposite to the guide slot <NUM>, and the first sliding plate <NUM> and the guide slot <NUM> are in a concave-convex sliding fit. In the third embodiment, in order to make it difficult for the separable block <NUM> to detach from the recessed slot <NUM>, the bottom wall of the recessed slot <NUM> is further provided with a limit slot <NUM> along the movement direction of the separable block <NUM>. The separable block <NUM> is provided with a second sliding plate <NUM> on the side wall opposite to the limit slot <NUM>, and the second sliding plate <NUM> and the limit slot <NUM> are in a concave-convex sliding fit. Obviously, in other embodiments, the bottom wall of the recessed slot <NUM> may not be equipped with a limited slot <NUM>, and at this time, the separable block <NUM> may not be correspondingly equipped with a second sliding plate <NUM>.

Please refer to <FIG>, a sliding puzzle toy <NUM> of the fourth embodiment of the present disclosure is provided, which differs from the third embodiment is that in the fourth embodiment, the length of the separable block <NUM> is smaller than the length of the recessed slot <NUM>. At this time, the part of the recessed slot <NUM> far away from the side wall 10b is recessed to form a receiving cavity <NUM>, and the receiving cavity <NUM> is connected to a moving block <NUM> through an elastic member (such as the first spring <NUM>). As the moving block <NUM> moves within the receiving cavity <NUM>, the moving block <NUM> has a first state adjacent to the separating block <NUM> and a second state overlapped with the separating block <NUM>. Therefore, when the moving block <NUM> moves downwards towards the receiving cavity <NUM>, it can still move the separating block <NUM> within the recessed slot <NUM> to the second state overlapped with the moving block <NUM>, achieving the opening of the recessed slot <NUM>.

In other embodiments of the present disclosure, the receiving cavity <NUM> in the recessed slot <NUM> can also be set adjacent to the side wall 10b according to different shapes and structures of the puzzle toy. The moving block <NUM> can also be movably connected to the receiving cavity <NUM> through other means, such as a structure with concave-convex moving fit, a structure with meshing moving fit, etc..

In the fourth embodiment, the recessed slot <NUM> includes two sub slots <NUM> that intersect with each other in a cross shape. The intersection position of the two sub slots <NUM> is recessed to form a receiving cavity <NUM>, and each sub slot <NUM> is sliding with two separable blocks <NUM>. By pushing any separable block <NUM> to move and overlap with the moving block <NUM>, the recessed slot <NUM> can be opened, so as to increase the utilization convenience of the sliding puzzle toy. It can be understood that since recessed slot <NUM> is composed of two cross intersecting sub slots <NUM>, four separable blocks <NUM> are respectively moved and set at the midpoint positions of the four sides of the bottom wall 10a on one bottom wall 10a of the main body <NUM>. At this time, guide slots <NUM> are set on either of the two vertical edges of the recessed slot <NUM> in bottom wall 10a, and first sliding plates <NUM> are set on both sides opposite to the guide slots <NUM> in any separable block <NUM>. Meanwhile, any separable block <NUM> is further provided with guide slots <NUM> on the side wall adjacent to the moving block <NUM>, allowing any separable block <NUM> to move onto the moving block <NUM>. In other embodiments of the present invention, according to the shape and setting requirements of the main body <NUM>, the recessed slot <NUM> may also include three or more intersecting sub slots <NUM>. At this time, the intersection position of any two sub slots <NUM> is recessed to form a receiving cavity <NUM>, and at least one separable block <NUM> is sliding inside each sub slot <NUM>.

In the fourth embodiment, the bottom wall of the receiving cavity <NUM> is provided with a retaining ring <NUM>. The end of the first spring <NUM> is detachably clamped and fixed on the retaining ring <NUM>, the other end of the first spring <NUM> is in contact with the moving block <NUM>, allowing the moving block <NUM> to move towards the receiving cavity <NUM> under external force. At the same time, when the external force on the moving block <NUM> is withdrawn, the moving block <NUM> can be pushed to reset through the first spring <NUM>, so that the moving block <NUM> can transform between the first state and the second state. It can be understood that in order to guide the moving block <NUM> to move in the correct direction within the receiving cavity <NUM>, the bottom wall of the receiving cavity <NUM> is also provided with a moving cavity <NUM>. At this time, the moving block <NUM> is provided with a connection post <NUM> on the side wall corresponding to the moving cavity <NUM>, and the connection post <NUM> can be movably connected within the moving cavity <NUM>. In other embodiments of the present invention, the receiving cavity <NUM> may not be provided with a moving cavity <NUM>, accordingly, the moving block <NUM> is not provided with a connection post <NUM>. The bottom wall of the moving cavity <NUM> and the connection post <NUM> can also be connected through an elastic member (such as a spring) to enhance the ability of the moving block <NUM> to reset automatically.

Please refer to <FIG>, a sliding puzzle toy <NUM> of the fifth embodiment of the present invention is provided, which differs from the fourth embodiment is that there are a plurality of guiding ribs <NUM> arranged at circumferential intervals on the side walls of the moving cavity <NUM>, and the end of each guiding rib <NUM> is provided with a first inclined surface <NUM>. The first inclined surface <NUM> is arranged in an inclined Z-shaped shape. At this time, there is no first spring <NUM> set on the retaining ring <NUM>, the connection post <NUM> can be movably connected in the moving cavity <NUM> through the pushing block 17a and the limit block 17b, so that when the external force on the moving block <NUM> is withdrawn, it is still possible to fix the moving block <NUM> in the receiving cavity <NUM> through the connection between the guiding ribs <NUM>, the pushing block 17a and the limit block 17b.

The pushing block 17a is fixedly and slidably connected with the connection post <NUM> between the plurality of guiding ribs <NUM>, so that the pushing block 17a needs to move back and forth in the direction limited by the guiding ribs <NUM>. The pushing block 17a is provided with serrated claws <NUM> in the circumferential direction at the end of the moving cavity <NUM>, which are used to contact with the limit block 17b to push the limit block 17b to move within the moving cavity <NUM>.

The limit block 17b is connected to the bottom wall of the moving cavity <NUM> through an elastic member (such as the second spring <NUM>), and the outer wall of the limit block 17b is provided with a plurality of positioning ribs <NUM>. Each positioning rib <NUM> is slidably connected between any two guiding ribs <NUM>, so that the limit block 17b needs to move back and forth in the direction restricted by the guiding ribs <NUM>. Each positioning rib <NUM> is provided with a second inclined surface <NUM> at the end opposite to the serrated claws <NUM>. The second inclined surface <NUM> contacts to the serrated claws <NUM>, so that the limit block 17b can slide on the guiding ribs <NUM> under the driving force of the pushing block 17a. The inclination direction and the inclination angle of each second inclined surface <NUM> are the same as those of the first inclined surface <NUM>, so that the second inclined surface <NUM> can move along the first inclined surface <NUM> when moving to the endpoint position of the first inclined surface <NUM>, therefore, each positioning rib <NUM> can rotate and move between adjacent guiding ribs <NUM> to achieve the positioning and resetting of the moving block <NUM>.

It should be noted that the process of moving block <NUM> moving within the moving cavity <NUM> by the pushing block 17a and the limit block 17b is roughly as shown in <FIG> and <FIG>. If the moving block <NUM> is pressed, the pushing block 17a will push the limit block 17b to slide within the guiding ribs <NUM> through the serrated claws <NUM>. At this time, the second spring <NUM> is in a compressed state. When the limit block 17b moves to the intersection of point A of the second inclined surface <NUM> and the first inclined surface <NUM>, the limit block 17b will be pushed by the elastic force of the second spring <NUM>, causing the second inclined surface <NUM> to cross point A and move along the first inclined surface <NUM> to point B of the first inclined surface <NUM>. At this time, the positioning rib <NUM> will be clamped on the first inclined surface <NUM>, enabling the moving block <NUM> to be positioned and fixed in the receiving cavity <NUM>, further increasing the utilization convenience of the sliding puzzle toy. If the moving block <NUM> is pressed again, the pushing block 17a will push the limit block 17b again to slide within the first inclined surface <NUM>. At this time, the second spring <NUM> is in a compressed state. When the limit block 17b moves to the intersection of point C on the second inclined surface <NUM> and the first inclined surface <NUM>, when the external force on the moving block <NUM> is withdrawn, the limit block 17b will be pushed by the elastic force of the second spring <NUM>, enabling the second inclined surface <NUM> cross point C and move along the first inclined surface <NUM> between any two guiding ribs <NUM>. Finally, under the force of the second spring <NUM>, the pushing block 17a is pushed to drive the moving block <NUM> to move and reset (as shown in <FIG>).

Please refer to <FIG>, a sliding puzzle toy <NUM> of the sixth embodiment of the present invention is provided, which differs from the fourth embodiment is that the bottom wall of the moving cavity <NUM> is provided with a mounting hole <NUM>. At this time, the receiving cavity <NUM> and the moving block <NUM> are still connected by the first spring <NUM>. The connection post <NUM> can be movably connected in the moving cavity <NUM> through the restriction block 18a and the restriction rod 18b to achieve that when external force on the moving block <NUM> is withdrawn, it is still possible to fix the moving block <NUM> in the receiving cavity <NUM> through the connection between the restriction block 18a and the restriction rod 18b.

The restriction block 18a is fixed and slidably connected to the connection post <NUM> in the mobile cavity <NUM>. One side of the wall of the restriction block 18a is provided with a channel <NUM>. In the sixth embodiment, an arrow-shaped raised rib <NUM> is arranged in the middle of the channel <NUM>, to make a M-shaped passage form inside the channel <NUM>. At this time, the channel <NUM> is provided with a recessed point <NUM> which is recessed downwards. It should be noted that in order to limit the movement path of the restriction rod 18b within the channel <NUM>, the side walls of the channel <NUM> are equipped with inclined planes that are guided in conjunction with the raised ribs <NUM>. In other embodiments of the present invention, channel <NUM> may not be limited to the M-shaped passage configuration in this embodiment, and the channel <NUM> may also be configured in other shapes with a recessed point <NUM>.

One end of the restriction rod 18b is fixed in the mounting hole <NUM>, and the other end of the restriction rod 18b corresponds to a raised rib <NUM> and can be movably connected in the channel <NUM>, so that the end of the restriction rod 18b can move with the movement of the restriction block 18a, and move to the recessed point <NUM> of the channel <NUM> to engage or separate, thereby achieving the positioning and resetting of the moving block <NUM>.

It should be noted that the process of the moving block <NUM> moving within the moving cavity <NUM> through the restriction block 18a and the restriction rod 18b is roughly as follows: as shown in <FIG> and <FIG>, if the moving block <NUM> is pressed, the connection post <NUM> will drive the restriction block 18a to move within the moving cavity <NUM>. At this time, the end of the restriction rod 18b moves to clamp with the recessed point <NUM> of the channel <NUM> under the guidance of the raised rib <NUM> and the side wall of the channel <NUM>, so that the moving block <NUM> can be positioned and fixed in the receiving cavity <NUM>, at this point, the first spring <NUM> is in a compressed state. If the moving block <NUM> is pressed again, the restriction block 18a moves with the connection post <NUM> in the moving cavity <NUM>, so that the end of the restriction rod 18b can move to separate from the recessed point <NUM> of the channel <NUM> under the guidance of the raised rib <NUM> and the side wall of the channel <NUM>. Therefore, when the external force on the moving block <NUM> is withdrawn, the end of the restriction rod 18b can move again in the channel <NUM>, finally, under the force of the first spring <NUM>, the moving block <NUM> is driven to move and reset (as shown in <FIG>).
