[0031] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is described below by the specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0032] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0033] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0034] Example: Figures 1 to 13 As shown, a magnetic puzzle toy includes at least a plurality of magnetic sheets 1 that can be stacked up and down or assembled horizontally and vertically, so that the magnetic sheets 1 can be assembled into a plurality of different shapes to enhance its playability. The center of the magnetic sheet 1 is hollowed out to form a hollow groove 11, and then the chess piece 9 is detachably installed in the hollow groove 11. The chess piece 9 can be used alone or assembled with the magnetic sheet 1. Then, a through hole 10 for a connecting tube 12 is provided at the center of the chess piece 9, so that the chess piece 9 can be stacked and assembled up and down. The provision of the connecting tube 12 can prevent the chess pieces from tipping over or scattering after stacking, thereby enhancing the fun. The length of the connecting tube 12 is adapted to the height of the stacked chess pieces 9, thereby ensuring the stability of the chess piece 9 during the stacking process.

[0035] In order to solve the problems of difficulty in subsequent magnet recovery and poor magnetic attraction effect caused by integral injection molding of the magnet and the magnetic sheet shell in the prior art, in this embodiment, a mounting groove 2 is opened on the side of the magnetic attraction sheet 1, and the specific number of the mounting grooves 2 on a single side can be set according to the single-side length of the magnetic attraction sheet 1. For example, two equidistant mounting grooves 2 can be opened on the sides of the square magnetic sheet and the triangular magnetic sheet, and mounting grooves 2 that are adapted to the distances of the square magnetic sheet and the triangular magnetic sheet are opened on the two waists and the upper bottom of the trapezoidal magnetic sheet. Four mounting grooves 2 are provided on the lower bottom of the sheet, and the distance between two adjacent mounting grooves 2 is adapted to the distance between the mounting grooves 2 on other magnetic sheets. Then, by installing magnetic splicing components in the above-mentioned mounting grooves 2, the assembly of square magnetic sheets with square magnetic sheets, triangular magnetic edges and trapezoidal magnetic sheets, the assembly of triangular magnetic edges with square magnetic sheets, triangular magnetic edges and trapezoidal magnetic sheets, the assembly of trapezoidal magnetic sheets with square magnetic sheets, triangular magnetic edges and trapezoidal magnetic sheets, etc. can be achieved, thereby ensuring the reliability of the assembly.

[0036] In the present embodiment, the magnetic splicing assembly is detachably installed in the installation groove 2. On the one hand, it is convenient to disassemble and assemble the magnetic splicing assembly, thereby reducing the difficulty of installation. On the other hand, it is convenient to recycle the magnetic block 6 such as magnets in the future, and violent disassembly can be avoided during the disassembly process, that is, the probability of collision between the magnetic block 6 and the outside is reduced, thereby ensuring the magnetism and quality of the magnetic block 6.

[0037] Specifically, the above-mentioned magnetic splicing assembly is mainly composed of an installation sleeve 4, an installation cover 5 and a magnetic block 6. In order to facilitate the installation of the magnetic block 6 in the above-mentioned installation sleeve 4, the installation sleeve 4 has a certain protective effect on the magnetic block 6. The above-mentioned installation sleeve 4 is a hollow and open structure. In order to prevent the magnetic block 6 from slipping out of the installation sleeve 4 during installation and use, the above-mentioned installation cover 5 is covered at the opening of the above-mentioned installation sleeve 4. The installation sleeve 4 and the installation cover 5 form an installation space for the magnetic block 6 to be installed.

[0038] Magnetic sheets on the market often place magnets in a larger space, which, on the one hand, results in poor magnetic attraction. On the other hand, magnets are prone to bounce and produce noise in a larger space, and are prone to collide with the surroundings, resulting in reduced magnetism, thus affecting the playability of magnetic sheet toys. In order to solve the above technical problems, in this embodiment, a limiter 8 is provided in the above-mentioned mounting sleeve 4. The limiter 8 can limit the position of the above-mentioned magnetic block 6 from moving too much, or prevent the magnetic block 6 from jumping, etc., thereby reducing the probability of collision between the magnetic block 6 and surrounding components, ensuring the magnetism of the above-mentioned magnetic block 6, and further ensuring the magnetic attraction reliability of the magnetic sheet. A pair of relatively arranged rotating holes 3 are provided in the above-mentioned mounting groove 2, that is, on the inner wall surface of the mounting groove 2. The above-mentioned mounting sleeve 4 and the above-mentioned mounting cover 5 both have a rotating part 7 adapted to the above-mentioned rotating hole 3. The above-mentioned rotating part 7 can be rotatably installed in the above-mentioned rotating hole 3, and the above-mentioned magnetic attraction block 6 can be rotatably installed in the above-mentioned limiting member 8. During use, the magnetic attraction block 6 can rotate under the action of external magnetic force, and the mounting sleeve 4 is also a rotatable installation method, which can quickly realize the assembly of two adjacent magnetic sheets while ensuring the reliability of the assembly. Compared with the prior art of integrally injecting the magnet into the magnetic sheet, the use of the magnetic attraction block 6 is reduced while reducing the production cost, thereby reducing the user's use cost, which is conducive to the promotion and application of the above-mentioned magnetic splicing components in the market.

[0039] In order to reduce the difficulty of production and ensure the overall aesthetics of the magnetic sheet, in this embodiment, the above-mentioned installation sleeve 4 is designed to be cylindrical, and the above-mentioned limiter 8 is eccentrically set in the above-mentioned installation sleeve 4. The main purpose of the limiter 8 is to limit the installation position of the above-mentioned magnetic block 6, so that the magnetic block 6 is installed in a smaller space to prevent the magnetic block 6 from jumping in a larger space, that is, in the above-mentioned installation sleeve 4. The magnetic block 6 can rotate in the limiter 8 and under the action of the external magnetic force. Specifically, the above-mentioned limiter 8 includes a limiter part 1 8-1 and a limiter part 2 8-2. The above-mentioned limiter part 1 8-1 and the above-mentioned limiter part 2 8-2 are both set in an arc and form a receiving cavity 8-3 that is compatible with the above-mentioned magnetic block 6. In order to reduce the difficulty of installation, the above-mentioned magnetic block 6 can also be designed to be cylindrical, and the inner diameter of the receiving cavity 8-3 is slightly larger than the outer diameter of the above-mentioned magnetic block 6. The purpose is to facilitate the installation of the above-mentioned magnetic block 6 while preventing it from jumping in the receiving cavity 8-3. In order to facilitate the taking of the magnetic block 6, the above-mentioned limiting part 1 8-1 is separated from the above-mentioned limiting part 2 8-2 and the tops are cut to form a step part 8-4, and a taking groove for fingers or other tools to reach in is formed between the two above-mentioned step parts 8-4.

[0040] In order to further reduce the amount of the magnetic block 6 and thus reduce the production cost, a cushion block 8-5 with a certain height is added to the accommodating cavity 8-3, and the specific shape of the cushion block 8-5 is not limited here. A length space for the installation of the magnetic block 6 is formed between the installation sleeve 4 and the installation cover 5. By adding the cushion block 8-5 in the space, the length of the magnetic block 6 can be shortened, that is, a length space for the installation of the magnetic block 6 is re-formed between the cushion block 8-5 and the installation cover 5. The length space is shortened, and the magnetic block 6 is shortened, thereby reducing the amount of the magnetic block 6, reducing the production cost of the magnetic sheet toy, and improving the economic benefits. In addition, the setting of the cushion block 8-5 can also limit the left and right movement of the magnetic block 6 in the length direction, thereby ensuring the installation position and magnetic effect of the magnetic block 6.

[0041] In order to facilitate the disassembly and assembly between the above-mentioned installation cover 5 and the installation sleeve 4, the above-mentioned installation cover 5 has an installation main body 5-1 located in the above-mentioned installation sleeve 4 and an installation hand-held part 5-2 located outside the above-mentioned installation sleeve 4. The outer wall of the above-mentioned installation main body 5-1 is arranged in contact with the inner wall of the above-mentioned installation sleeve 4, that is, the above-mentioned installation main body 5-1 is embedded in the above-mentioned installation sleeve 4. In order to further ensure the overall aesthetics, the outer diameter of the above-mentioned installation hand-held part 5-2 is set to be consistent with the outer diameter of the above-mentioned installation sleeve 4. In order to ensure the overall quality of the magnetic sheet and reduce the amount of manufacturing materials, the above-mentioned installation main body 5-1 in this embodiment is arranged in a cylindrical shape and a plurality of weight-reducing grooves 5-3 arranged at intervals are formed on the wall surface facing the above-mentioned magnetic suction block 6.

[0042] The above-mentioned limit member 8 and the above-mentioned mounting sleeve 4 are integrally formed. The one-piece molding design can enhance the connection strength between the limit member 8 and the mounting sleeve 4, and reduce the risk of structural failure due to improper connection or wear; the one-piece molding can reduce additional assembly steps, reduce production costs and time, and improve production efficiency; the one-piece molding can also ensure the precise fit between the limit member 8 and the mounting sleeve 4, thereby ensuring the uniqueness of the installation position of the above-mentioned magnetic suction block 6 and improving assembly efficiency.

[0043] In order to ensure the smoothness and stability of the magnetic splicing assembly as a whole during rotation, in this embodiment, the rotating hole 3 is designed as a circular hole, and the rotating part 7 is designed as a cylindrical structure. The circular hole and cylindrical structure are the most basic geometric shapes, and their manufacture and processing are relatively simple, which can improve production efficiency and reduce costs. The matching mode of the circular hole and the cylinder can also reduce the friction and wear at the contact point because the contact area is small during rotation, and the cylindrical surface can evenly distribute the load, thereby extending the service life of the magnetic splicing assembly, reducing the cost of use, and enhancing the fun.

[0044] The magnetic attraction block 6 includes but is not limited to a magnet, and its main purpose is to realize the magnetic attraction of the magnetic splicing component, thereby realizing the assembly of the magnetic sheets.

[0045] In the prior art, in order to reduce the difficulty of manufacturing, the corners of the magnetic sheet 1 are usually designed as right angles. During actual assembly, the right angles will scratch the skin on the one hand, and on the other hand, two magnetic sheets 1 with right angles will fit tightly together, which can easily cause injuries such as pinching hands to children and other users, affecting the user experience. In order to solve this technical problem, in this embodiment, the corners of the magnetic sheet 1 are all rounded, and an anti-pinch groove is formed between two adjacent magnetic sheets 1 to prevent pinching hands. The rounded corner setting method can increase the overall aesthetics of the magnetic splicing toy.

[0046] A magnetic splicing toy in the present embodiment has an ingenious structure. By providing a plurality of magnetic sheets 1, the center position of the magnetic sheet 1 is hollowed out to form a hollow groove 11, and then a chess piece 9 is detachably installed in the hollow groove 11. The chess piece 9 can be used alone or assembled with the magnetic sheet 1. Then, a through hole 10 for a connecting tube 12 is provided at the center position of the chess piece 9, so that the chess piece 9 can be stacked and assembled up and down. The provision of the connecting tube 12 can prevent the chess pieces 9 from tipping over or scattering after being stacked, thereby enhancing the fun. In the present embodiment, an installation groove 2 is provided on the side of the magnetic sheet 1, and the magnetic splicing assembly is directly installed in the installation groove 2, which is convenient for the disassembly and assembly of the magnetic splicing assembly, and it is convenient to recycle magnetic blocks such as magnets and ensure the quality of the magnets.

[0047] This embodiment also installs the magnetic block 6 in the limiting member 8, and then sets the limiting member 8 in the mounting sleeve 4. During use, the magnetic block 8 can rotate under the action of the external magnetic force, and the mounting sleeve 4 is also a rotatable installation method, which can quickly realize the assembly of two adjacent magnetic sheets while ensuring the reliability of the assembly. Compared with the prior art of integrally injecting the magnet into the magnetic sheet, the use of the magnetic block is reduced while reducing the production cost, thereby reducing the user's use cost, which is conducive to the promotion and application of the above-mentioned magnetic splicing components in the market.
