Patent Description:
The present disclosure relates to the field of toys, in particular, to a magnetic attraction toy.

3D magnetic puzzle building blocks are increasingly popular toys in recent years, which can be used to build three-dimensional models and help develop children's imagination. In most of existing magnetic attraction toys on the current market, a magnet is arranged in an internal cavity of a plastic shell. A magnetic force of the magnet through inner walls of two layers of plastic becomes relatively low, resulting in a weak magnetic attraction force. As a result, the magnetic attraction toys can be used to build a limited number of three-dimensional models, and have low playability, which greatly affects the user experience. Therefore, there is an urgent need for providing a magnetic attraction toy with a low price, high acceptability, strong magnetic force, high strength, high safety and high playability, which is convenient for users to put out various models to improve the user experience.

<CIT> discloses a magnetic module assembly having opposing geometric frames and a plurality of connector struts that connect and extend between the geometric frames. Each of the geometric frames has a plurality of segments, with each segment having a magnet enclosure integrated in the segment. The segments are interposed between attachment points formed in the geometric frame, each attachment point having a pair of receptacles that are sized and shaped to receive a corresponding pair of connector pins from a connector strut. The segments of a geometric frame have a larger thickness compared to that of the attachment points, making the attachment points of the frame frangible.

<CIT> discloses a magnetic sheet, comprising: a frame structure, a plurality of magnetic structures are arranged on the periphery of the frame structure, the frame structure and the plurality of magnetic structures are integrally formed; wherein each of the plurality of magnetic structures comprises: a steel pipe, a magnet arranged in the steel pipe and plugs at both ends of the steel pipe. Through the magnetic structures which are integrated with the frame structure, after the magnetic sheet is used for a long time, the magnetic structures still can be attached to a magnetic sheet body, and the problems that the magnetic structures are damaged and fall off are avoided.

In order to overcome the shortcomings in the prior art, the present disclosure provides a magnetic attraction toy with a low price, high acceptability, strong magnetic force, high strength, high safety and high playability, which is convenient for users to put out magnetic attraction toys of various models to improve the user experience.

The base is also provided with locating pillars. The mounting frame is provided with locating holes. When the locating holes sleeve the locating pillars, the cover body is covered on the base to stop the mounting frame in the base and to stop the magnetic attraction member in the limiting gap. The magnetic attraction member includes a hollow iron tube and a magnet. The magnet is located in the iron tube. One end of the iron tube is provided with a first opening. The other end of the iron tube is provided with a second opening. The mounting frame includes a first clamping piece and a second clamping piece.

In addition, the first clamping piece and the second clamping piece are respectively clamped to two ends of the iron tube. On the one hand, the ribs welded with the first clamping piece and the second clamping piece are arranged on the base and the cover body, so that the number of welding lines is greatly increased, and a decrease in the quality of a product caused by difficulty in finding lack of weld is prevented. On the other hand, the thickness of an entire plastic building block is greatly increased, so that the overall torque resistance and tensile strength are greatly improved in order that children think a toy building block body cannot be broken with bare hands. A safety threat caused by the following fact can be effectively avoided: when playing the toy, a child swallows the magnet carelessly since a toy shell is broken. The safety of the magnetic attraction toy is then improved. Further, every country does not allow strong magnets to be exposed in children's products. The magnet is fixed in the iron tube, on the one hand, this regulation is met, on the other hand, magnetism of the magnetic attraction toy is improved.

A transverse length of the iron tube is greater than that of the magnet. Specifically, the transverse length of the iron tube is twice that of the magnet.

By means of the above structure, the magnetic attraction member can be exposed from the base and the cover body through the limiting gap. Compared with the prior art that a magnet is arranged in a plastic shell and fails in direct contact such that the magnetism is lowered, the present disclosure achieves direct contact between magnetic attraction toys, thus enhancing the first stage of magnetic force. Furthermore, the magnetic attraction member includes the iron tube and the magnet located in the iron tube, so that the transverse length of the iron tube can be set to be greater than that of the magnet. Specifically, the transverse length of the iron tube can be set to be twice that of the magnet, and the first clamping end and the second clamping end can be inserted into two ends of the iron tube, so that a magnetic attraction contact area between the magnetic attraction toys can be multiplied, and the magnet can still be fixed in a center position of the iron tube to provide a stronger and more stable magnetic attraction force, thus enhancing the second stage of magnetic force. In addition, the iron tube wrapping around the magnet makes magnetic induction lines around the magnet distributed intensively, so that the magnetic induction intensity around a surface of the magnetic attraction body becomes stronger, thus enhancing the third stage of magnetic force. A surface contact magnetic force of the magnetic attraction toy is enhanced by superposition of the enhancement of the three stages of magnetic forces, so that a user can put out a more three-dimensional, complicated and stable model using the magnetic attraction building blocks without increasing the cost for a strong magnet, and children's imagination can be developed more fully, which greatly increases the fun of experience of children. In addition, the first clamping piece and the second clamping piece are respectively clamped to two ends of the iron tube. On the one hand, the ribs welded with the first clamping piece and the second clamping piece are arranged on the base and the cover body, so that the number of welding lines is greatly increased, and a decrease in the quality of a product caused by difficulty in finding lack of weld is prevented. On the other hand, the thickness of an entire plastic building block is greatly increased, so that the overall torque resistance and tensile strength are greatly improved in order that children think a toy building block body cannot be broken with bare hands. A safety threat caused by the following fact can be effectively avoided: when playing the toy, a child swallows the magnet carelessly since a toy shell is broken. The safety of the magnetic attraction toy is then improved. Further, every country does not allow strong magnets to be exposed in children's products. The magnet is fixed in the iron tube. On the one hand, this regulation is met, and on the other hand, the magnetic attraction toys can be in direct contact through the surfaces of the iron tubes. Meanwhile, magnetic fields around the magnet are also strengthened.

In this embodiment, the base and the cover body can be provided with triangular, square, hexagonal, pentagonal, rhombus-shaped, trapezoid, fan-shaped or semicircular cross sections or cross sections in other shapes. When the base and the cover body can be provided with square cross sections, there are four magnetic attraction members and four mounting frames, which are respectively arranged on an upper side, lower side, left side and right side of the square base.
