Patent Description:
A bracket is often mounted on a wall or ceiling, which is a basic component for supporting objects. When in use, it is generally matched with rod components, and the rod components are connected to adjacent brackets, so that the rod is hung in the air. This kind of rod is generally used for items such as hanging curtains, washing supplies, projection curtains.

There are generally two connection ways between the bracket and the rod component.

The first one is locking fixing. However, the rod components are often more easily damaged than brackets, for example, bending, deforming or breaking. For example, in the case of hanging the curtain, the curtain often need to be cleaned and changed regularly, and thus such bracket is not convenient for use since it is installed in the wall or ceiling and cannot be detached conveniently.

The second one is a bracket provided with a groove on the surface thereof, in which the two ends of the rod are provided Although this way can achieve the purpose of replacing the rod components, the rod components tends to loosen relative to the grooves, having a poor stability.

A Chinese patent with an application number <CIT>discloses a mounting bracket according to the preamble of claim <NUM>, whereby said bracket comprises a base, and the base is integrally connected with an U-shaped supporting portion with an opening facing upward, and also includes a snap-fit arranged in an arc shape, an opening of an inner wall of the U-shaped supporting portion is provided with a snap-in groove, and an inner arc of the snap-fit extends towards the inner side to form a connecting portion that cooperates with the snap-in groove, an end of the connecting portion is provided with a first limiting part with a triangular cross-section on the side, the first limiting portion abuts against an outer wall of the U-shaped supporting portion, the utility model aims to provide a mounting bracket that can be suitable for curtain guide rods of different diameters and has better stability.

In order to enable a rod component to be mounted on/detached from a bracket while ensuring sufficient stability, the present application provides a bracket.

A bracket provided in the present application adopts the following technical solution:
The invention is as defined in claim <NUM>.

In the above technical solution, the base can be externally connected to the wall or ceiling, and the damping element can be selected depending on the specification of the rod components. The damping element can be movably installed into the mounting hole or fixed through the mounting hole in advance. During the mounting process, taking an upward opening of the groove as an example, after the rod component is pressed into the groove from top to bottom, the damping element cannot move up and down due to the limitation of the mounting hole, thus the damping element will stop the rod component from moving up by damping. In this way, disassembling can be realized only by applying a force big enough to the rod component. This achieves the effect that the rod component can be mounted on or detached from the bracket, while ensuring sufficient stability after mounting, whereby the detachable mounting of the damping element can be realized. The damping element can be replaced according to the specification of the rod component, no matter whether the anti-detachment structure can be detached directly or destructively.

When the rod component is pressed against the surface of the damping head, an end of the primary arc portion connected with the primary arc portion and the secondary arc portion will be displaced and deformed outward under the guidance of the arc transition portion between the groove wall of the groove and the base, so as to provide a better avoidance for installing the rod component. The abutting connection of the other end of the secondary arc portion provides elastic structural support to avoid excessive deformation. After the rod component is installed into the groove, if it is forced to fall off, the portion of the primary arc portion towards the bottom of the groove will be pressed towards the opening of the groove, so that the middle portion of the primary arc portion toward the groove relative to the mounting hole, and the rod component will be easily stopped by the damping head. Hence, a simple-to-install and difficult-to-separate structure for a rod can be formed, providing the rod component with convenient mounting and higher stability. In addition, the convex portion serves an auxiliary function since the presence thereof will force the rod component to squeeze both the primary arc portion and the secondary part at the same time when being detached.

A limitation can be realized by rotation after the tailstock and the limiting column pass through the mounting hole. The specific rotation degree can be set according to the position of the limiting column relative to the tailstock.

Optionally, the mounting hole is a rectangular hole, a long side of the rectangle of the mounting hole is in the same direction as that of an axis of the hooking part, a projection of the tailstock along the long direction is of polygon, the polygon has even number of sides, at least six sides, and the tailstock is made of elastic material; and when the tailstock is in s final assembled state of the damping element and the hooking part, the two opposite faces of the tailstock are fitted with the two opposite and nearest hole walls of the mounting hole.

In the above technical solution, because the hooking part is an arc structure as a whole, in the case of an upward opening of the groove, when the length of the limiting column is in a horizontal direction, a portion of the limiting column abutting against an outer surface of the hooking part can be regarded as a straight line, and when the length of the limiting column is in an upward direction, a portion of the limiting column abutting against the outer surface of the hooking part can be regarded as a curve. Therefore, after the tailstock and the limiting column are inserted from the mounting hole, the rotation of the tailstock changes the orientation of the limiting column rotates from a horizontal direction to a vertical direction. In this process, the tailstock will also be further tightened so that the damping head can closely fit with the inner wall of the groove. In addition, in the process of rotation, since the tailstock is polygonal and the surface thereof fits with the hole wall of the mounting hole, the tailstock is rotated mainly depending on the elastic deformation of the tailstock. After the rotation is completed, the tailstock will not be easy to deflect due to the limitation provided by its shape, so as to ensure a structural stability during use.

Optionally, the tailstock is provided with a sliding slot on at least one group of opposite surfaces other than that provided with the limit column, an opening width of the sliding slot on the surface of the tailstock is less than a width of an inner cavity of the sliding slot, a side of the sliding slot close to the damper element is provided with an inlet slot, the sliding slot is slidably connected with a filling block configured to fill a gap between the tailstock and the mounting hole, and a glue filling slot laterally penetrating through the tailstock along the tailstock is recessed between the sliding slot and the inlet slot.

In the above technical solution, after the tailstock is rotatably installed in place, the filling block can be inserted through the inlet slot, then move along the sliding slot and fill the gap between the tailstock and the mounting hole. Therefore, the tailstock cannot rotate, and the tailstock cannot move in the direction away from the mounting hole due to the restriction of the limiting column. After the filling block is installed, a solidifiable glue can be injected into the glue filling slot from the side of the tailstock. After the solidifiable glue solidifies, since the glue filling slot is laterally positioned on the sliding path of the sliding block, it can play a good limiting role with sufficient strength. When the damping element is desired to be detached, a stick or needle smaller than the glue filling slot or the glue filling slot can be used to eject out the solidifiable glue.

Optionally the tailstock is provided with a sliding slot on at least one group of opposite surfaces other than that provided with the limit column, an opening width of the sliding slot on the surface of the tailstock is less than a width of an inner cavity of the sliding slot, a side of the sliding slot close to the damper element is provided with an inlet slot, the sliding slot is slidably connected with a filling block configured to fill a gap between the tailstock and the mounting hole, and a glue filling slot laterally penetrating through the tailstock along the tailstock is recessed between the sliding slot and the inlet slot.

In the above technical solution, for installation, firstly, the oval short edge of the tailstock is moved corresponding to the oval short edge of the mounting hole until the limiting column touches the inner wall of the groove. Then the tailstock is rotated to elastically deform the tailstock, and the limiting column falls into a position where it can pass through the mounting hole. Then, the limiting column is inserted into the mounting hole along with the tailstock and passes through the mounting hole. In this state, the tailstock has the elastic force of reverse rotation for restoring, and can be released or manually reversely rotated. In this way, the limiting column will abut against a surface of the hooking part far away from the damping head, playing the role of limiting and preventing detachment.

In summary, the present application includes at least one of the following beneficial technical effects.

Listing of reference signs: <NUM>.

The present application is further described in detail below in combination with the <FIG>.

The present application discloses a bracket.

Referring to <FIG> and <FIG>, a bracket includes a base <NUM> and a hooking part <NUM>, and the base <NUM> is integrated with the hooking part <NUM>. In this embodiment, the base <NUM> and the hooking part <NUM> are made of metal material. In this embodiment, the base <NUM> is L-shaped, and one of the L-shaped surfaces is provided with one or more holes for connecting with a wall or ceiling through a screw bolt. In other embodiments, it also can be of other shapes adapted to a space corresponding to the wall or ceiling, such as V-shape. In this embodiment, the hooking part <NUM> is U-shaped, and the L-shaped end of the base <NUM> without a hole is connected with the U-shaped end of the hooking part <NUM>. In other embodiments, the hooking part <NUM> can be of other shapes which can clamp a rod, such as C-shape, V-shape or the like.

A curved portion of the hooking part <NUM> forms a groove <NUM>, and the groove wall of the groove <NUM> connected with the base <NUM> is provided with a mounting hole <NUM> which penetrates through the U-shaped surface of the hooking part <NUM>.

The mounting hole <NUM> is provided with a damping element <NUM> which includes a tailstock <NUM> and a damping head <NUM>. The tailstock <NUM> penetrates through the mounting hole <NUM>, and the damping head <NUM> enters the groove <NUM>. In this embodiment, the tailstock <NUM> and the damping head <NUM> are integrally injection molded, and the materials of the tailstock <NUM> and the damping head <NUM> can be the same or different. If different, two-color injection molding is adopted, and the material damping factor of the damping head <NUM> is greater than that of the tailstock <NUM>. This embodiment takes the same material as an example.

Surfaces of the damping head <NUM> close to and away from the tailstock <NUM> are arc surfaces, and all of the arc surfaces of the damping head <NUM> bulge toward a side away from the tailstock <NUM>. A damping pattern <NUM> is provided on a surface of the damping head <NUM> away from the tailstock <NUM>. An elastic cushion block <NUM> is fixed on one side of the damping head <NUM> close to the tailstock <NUM>, the elastic cushion block <NUM> abuts against a groove wall of the groove <NUM>, and at least one of the two arc-shaped ends of the damping head <NUM> abuts against the groove wall of the groove <NUM>. After installing damping portion <NUM>, both ends of the damping head <NUM> abut against the groove wall of the groove <NUM>, so that only elastic deformation will occur during the installation of the rod component, avoiding jumping.

Referring to <FIG> and <FIG>, the tailstock <NUM> is provided with an anti-detachment structure <NUM> to prevent the tailstock <NUM> from separating from the mounting hole <NUM>. In this embodiment, the anti-detachment structure <NUM> includes two inclining blocks <NUM> fixed at opposite side walls of the tailstock <NUM>, and the inclining blocks <NUM> are elastic. A surface of the inclining block <NUM> away from the damping head <NUM> is an inclined guiding surface <NUM>. When the tailstock <NUM> is mounted in the mounting hole <NUM>, the inclined guiding surface <NUM> contacts the hole wall of the mounting hole <NUM> earlier than other surfaces of the inclining block <NUM> to provide direction guiding, elastically deforms, penetrats through the mounting hole <NUM>, and restore its shape. With this, the surface of the inclining block <NUM> close to the damping head <NUM> abuts against the surface of the hooking part <NUM> to prevent the tailstock <NUM> from detachment. A surface of the inclining block <NUM> near the damping head <NUM> is a stopping surface <NUM>, and the acute angle between the stopping surface <NUM> and the side wall of the tailstock <NUM> at least exceeds the acute angle between the inclined guiding surface <NUM> and the side wall of the tailstock <NUM> by <NUM>°. In this embodiment, the mentioned angle relative to the guide inclined plane <NUM> is <NUM>°, and the mentioned angle relative to the stopping surface <NUM> is <NUM>°. Therefore, after the inclining block <NUM> penetrates through the mounting hole <NUM>, the stopping surface <NUM> can further tighten the damping head <NUM> to press the damping head <NUM> against the inner wall of the groove <NUM>, playing the role of anti-detachment. If a detachment is desired, a force sufficient to elastically deform the stopping surface <NUM> and pull the tailstock <NUM> out of the hooking part <NUM> can be applied. After pulling out, the damping element <NUM> can be reinstalled and used.

In this embodiment, the inclining block <NUM>, the elastic cushion block <NUM> and the tailstock <NUM> are integrally injection molded.

The implementation principle of Embodiment <NUM> is:
The tailstock <NUM> of the damping element <NUM> can be inserted into the mounting hole <NUM> of the hooking part <NUM>, during which the damping element <NUM> is automatically pressed against the surface of the groove <NUM> of the hooking part <NUM>. Then the base <NUM> will be mounted on a wall and ceiling. A rod component can be mounted in two or more the brackets, which is not easy to fall off since it will be limited by the damping head <NUM> after being clamped in the groove <NUM>.

After the rod component is detached forcefully, if it is desired to replace a rod with different specifications, the damping element can also be pulled out and different damping elements can be mounted, for achieving the same damping effect.

Referring to <FIG>, the difference between this embodiment and Embodiment <NUM> is that, the surfaces of the damping head <NUM> close to and away from the tailstock <NUM> are multi-segment arc surfaces, and all the arc surfaces of the damping head <NUM> bulge toward a side away from the tailstock <NUM>. A connection portion between the groove wall of the groove <NUM> and the base <NUM> assumes an arc surface. An arc surface of the damping head <NUM> is divided into a primary arc portion <NUM> and a secondary arc portion <NUM>. One end of the primary arc portion <NUM> abuts against the groove wall of the groove <NUM>, and the end of the primary arc portion <NUM> connected with the secondary arc portion <NUM> abuts against the arc surface of the groove wall of the groove <NUM> connected with the base <NUM>. All the ends of the secondary arc portion <NUM> abut against the arc surface connected between the groove wall of the groove <NUM> and the base body <NUM>. A side wall of the groove <NUM> away from the base is provided with a convex portion <NUM>, and the convex portion <NUM> faces a connecting portion between the multi-segment arc surfaces of the damping head <NUM>.

In this way, when the rod component is pressed against the surface of the damping head <NUM>, an end of the primary arc portion <NUM> connected with the secondary arc portion <NUM> will be displaced and deformed outward under the guidance of the arc transition portion between the groove wall of the groove <NUM> and the base <NUM>, so as to provide better avoidance for installing the rod component. After the rod component is installed into the groove <NUM>, if it is forced to fall off, the portion of the primary arc portion <NUM> towards the bottom of the groove will be pressed towards the opening of the groove <NUM>, so that the middle portion of the primary arc portion <NUM> is pulled toward the groove <NUM> relative to the mounting hole <NUM>, and the rod component will be easily stopped by the damping head <NUM>. Hence, a simple-to-install and difficult-to-separate structure for a rod can be formed.

Referring to <FIG> and <FIG>, the difference between this embodiment and Embodiment <NUM> is that, the two opposite side walls of the tailstock <NUM> are respectively provided with a limiting column <NUM>, the mounting hole <NUM> includes a main hole portion (not shown) for the tailstock <NUM> to pass through and a branch hole portion (not shown in the figure) for the limiting columns <NUM> to pass through, and the number of the branch holes is equal to that of the limiting columns <NUM>. The main hole portion and the branch hole portion can be holes with different cross-sectional shapes respectively. For example, the main hole portion is a square hole and the branch hole portion is a circular hole. Alternatively, they can jointly form a regular pattern. For example, a square hole can be divided into a main hole portion for the tailstock <NUM> to pass through and a branch hole portion for the limiting column <NUM> to pass through. In this embodiment, the mounting hole <NUM> is a rectangular hole as an example. A long side direction of the rectangle of the mounting hole <NUM> is in the same direction as the axis direction of the hooking part <NUM>.

The tailstock <NUM> made of elastic material. the projection of the tailstock <NUM> along the long direction is of polygon, the polygon has an even number of sides. The number of sides of polygon is at least six. In this embodiment, the tailstock <NUM> is an octagonal prism as an example. In a final assembled state of the damping element <NUM> and the hooking part <NUM>, the two opposite faces of the tailstock <NUM> are fitted with the two opposite and nearest hole walls of the mounting hole <NUM>.

Taking an upward opening of the groove <NUM> as an example, when the length of the limiting column <NUM> is in a horizontal direction, a portion of the limiting column <NUM> abutting against a side surface of the hooking part <NUM> can be regarded as a straight line, and when the length of the limiting column <NUM> is in a upward direction, a portion of the limiting column <NUM> abutting against a side surface of the hooking part <NUM> can be regarded as a curve. Therefore, after the tailstock <NUM> and the limiting column <NUM> are inserted from the mounting hole <NUM>, the rotation of the tailstock <NUM> changes the orientation of the limiting column <NUM> from a horizontal direction to a vertical direction. In this process, the tailstock <NUM> will also be further tightened so that the damping head <NUM> can closely fit with the inner wall of the groove <NUM>. In addition, in the process of rotation, since the tailstock <NUM> is polygonal and the surface thereof fits with the hole wall of the mounting hole <NUM>, the tailstock <NUM> is rotated mainly depending on the elastic deformation of the tailstock <NUM>. After the rotation is completed, its shape can prevent reverse rotation.

Referring to <FIG>, the difference between this embodiment and Embodiment <NUM> is that, the tailstock <NUM> is provided with a sliding slot <NUM> on other opposite surfaces other than that provided with the limit column <NUM>. The opening width of the sliding slot <NUM> on the surface of the tailstock <NUM> is less than the width of the inner cavity of the sliding slot <NUM>. A side of the sliding slot <NUM> close to the damper element <NUM> is provided with an inlet slot <NUM>, and the sliding slot <NUM> is slidably connected with a filling block <NUM> which can be used to fill the gap between the tailstock <NUM> and the mounting hole <NUM>. A glue filling slot <NUM> laterally penetrating through the tailstock <NUM> along the tailstock <NUM> is recessed between the sliding slot <NUM> and the inlet slot <NUM>.

After the tailstock <NUM> is rotatably installed in place, the filling block <NUM> can be inserted through the inlet slot <NUM>, then move along the sliding slot <NUM> and fill the gap between the tailstock <NUM> and the mounting hole <NUM>. Therefore, the tailstock <NUM> cannot rotate, and the tailstock <NUM> cannot move in the direction away from the mounting hole <NUM> due to the restriction of the limiting column <NUM>. After the filling block <NUM> is installed, a solidifiable glue can be injected into the glue filling slot <NUM> from the side of the tailstock <NUM>. After the solidifiable glue solidifies, since the glue filling slot <NUM> is laterally positioned on the sliding path of the sliding block, it can play a good limiting role with sufficient strength. When the damping element <NUM> is desired to be detached, a rod or needle smaller than the glue filling slot <NUM> or the glue filling slot <NUM> can be used to eject out the solidifiable glue.

In this embodiment, the elastic cushion block <NUM> can have a reduced thickness or directly omitted to provide convenience for providing the sliding slot <NUM>. In other embodiments, the inlet slot <NUM> and the glue filling slot <NUM> can be provided at one end away from the damping head <NUM>, so that the filling block <NUM> can be inserted into the sliding slot <NUM> from a side of the hooking part <NUM> (not shown) away from the groove <NUM> (not shown), and the thickness of the corresponding elastic cushion block <NUM> can remained unchanged.

Referring to <FIG>, the difference between this embodiment and Embodiment <NUM> is that, the mounting hole <NUM> is an oval hole. The oval long axis of the mounting hole <NUM> is in the same direction as the axis of the hooking part <NUM>. The tailstock <NUM> is an oval cylinder, the oval long axis of the tailstock <NUM> is shorter than the oval long axis of the mounting hole <NUM>, the oval short axis of the tailstock <NUM> coincides with the oval short axis of the mounting hole <NUM>, and the tailstock <NUM> is elastic. The long axis length of the tailstock <NUM> is sufficient to be reduced to be consistent with the short axis length of the mounting hole <NUM> within the elastic deformation range. The limiting column <NUM> is fixed in the area where the short shaft of the tailstock <NUM> is located.

In this embodiment, the oval short axis of the tailstock <NUM> coincides with the oval short axis of the mounting hole <NUM>.

For installation, firstly, the oval short edge of the tailstock <NUM> is moved corresponding to the oval short edge of the mounting hole <NUM> until the limiting column <NUM> touches the inner wall of the groove <NUM>. Then the tailstock <NUM> is rotated to elastically deform the tailstock <NUM>, and the limiting column <NUM> falls into a position where it can pass through the mounting hole <NUM>. Then, the limiting column <NUM> is inserted into the mounting hole <NUM> along with the tailstock <NUM> and passes through the mounting hole <NUM>. In this state, the tailstock <NUM> has the elastic force of reverse rotation for restoring, and can be released or manually reversely rotated. In this way, the limiting column <NUM> will abut against a surface of the hooking part <NUM> far away from the damping head <NUM>, playing the role of limiting and preventing detachment.
