Technical Field
[0001] This utility model relates to the field of toy technology, and more particularly to a magnetic building block with a variable shape. Background Technology
[0002] Building block toys, as toys with high playability and expandability, are very popular among children. Current building block toys generally have a main shell, the internal cavity of which is divided into multiple receiving slots. Several magnets are placed in the corresponding receiving slots. A cover is fixedly connected to each of the two openings of the main shell, thus assembling a magnetic building block with built-in magnets. For example, a magnetic building block is provided in Chinese patent application CN220834120U. However, due to the inherent structural limitations, such magnetic building blocks can only be used as building block assembly toys, with relatively simple gameplay and limited playability, failing to meet the diverse play needs of consumers. Utility Model Content

[0004] To achieve the aforementioned objectives, this utility model provides a variable-form magnetic building block, comprising a first shell and a second shell. Both the first shell and the second shell are hollow structures and each includes an open end and a closed end. The open ends of the first shell and the second shell are rotatable relative to each other through a rotating structure and can be fixedly separated through a locking structure. The rotating structure and the locking structure are arranged opposite to each other, allowing the first shell and the second shell to rotate relative to each other to open or close. The open end of the first shell has multiple connecting holes that are arranged opposite to each other or circumferentially spaced. Each connecting hole is rotatably connected to a limb member, and each limb member can rotate to the outside or inside of the first shell. The closed ends of the first shell and the second shell are respectively provided with multiple receiving slots at intervals, and each receiving slot contains a magnet.
[0005] As a preferred embodiment, the rotating structure includes a first connecting block and a mounting hole disposed between the open ends of the first housing and the second housing, the first connecting block being matched and connected to the mounting hole, wherein a first rotating shaft is provided protruding on both sides of the first connecting block, and a first groove is provided on both sides of the mounting hole for rotatably connecting the first rotating shaft.
[0006] As a preferred embodiment, the mounting hole is recessed on one side of the opening end of the first housing, and a first limiting block is provided on the inner wall of the first housing corresponding to the mounting hole. The first limiting block is used to restrict the first connecting block to be connected in the mounting hole.
[0007] As a preferred embodiment, the locking structure includes a second connecting block and a positioning hole disposed between the open ends of the first housing and the second housing, wherein the second connecting block can be inserted and fixed in the positioning hole.
[0008] As a preferred embodiment, the limb component includes two upper limb components and one lower limb component, the upper limb components and the lower limb components are respectively matched and connected in the corresponding connecting holes, wherein each upper limb component has a second rotating shaft protruding from both sides, the lower limb component has a third rotating shaft protruding from both sides, and each connecting hole has a second groove recessed on both sides for rotatably connecting the second rotating shaft or the third rotating shaft.
[0009] As a preferred embodiment, the inner wall of the first housing is provided with a second limiting block corresponding to each of the connection holes. The second limiting block is used to restrict the upper limb and the lower limb to be connected in the corresponding connection hole.
[0010] As a preferred embodiment, the first housing includes a first square frame and a first cover plate that are fixedly connected. The first square frame has the rotating structure, the locking structure and the connecting hole on one of its open ends. The first square frame has a first plug-in block and a first groove on the other open end. The first cover plate has a second plug-in block and a second groove on one side. The second plug-in blocks are inserted into and fixed to the first plug-in blocks in a corresponding manner. The second grooves are connected to the first grooves in a corresponding manner to form the receiving grooves.
[0011] As a preferred embodiment, the second housing includes a second square frame and a second cover plate that are fixedly connected. The rotating structure and the locking structure are provided on one open end of the second square frame, and a third insertion block and a third groove are provided on the other open end of the second square frame. A fourth insertion block and a fourth groove are provided on one side of the second cover plate. The fourth insertion block is inserted and fixed to the third insertion block in a corresponding manner, and the fourth groove is connected to the third groove in a corresponding manner to form the receiving groove.

[0013] Therefore, based on the technical means of this utility model, the effects that this utility model can achieve are briefly described as follows: The variable-form magnetic building block provided by this utility model innovatively improves the shell structure of traditional magnetic building blocks. By setting a hollow first shell and a second shell, a relative rotation structure and a locking structure are set between the open ends of the first shell and the second shell. Furthermore, several receiving slots with fixed magnets are set on the closed ends of the first shell and the second shell respectively. In addition, multiple limbs are rotatably connected to the first shell. Each limb can be rotated to the inside or outside of the first shell. Thus, consumers can change the form of the magnetic building block by rotating the first shell and the second shell relative to each limb to change their relative position. This allows it to become a traditional magnetic building block toy for building games, or a toy in the form of a doll or an animal for games. The game functions are relatively rich and the playability is higher. Attached Figure Description

[0022] Please refer to the following at the same time Figure 1-5 This embodiment provides a variable-form magnetic building block, including a first shell 1 and a second shell 2. Both the first shell 1 and the second shell 2 are hollow structures and each includes an open end and a closed end. The open ends of the first shell 1 and the second shell 2 are rotatable relative to each other via a rotating structure and can be fixedly separated via a locking structure. The rotating structure and the locking structure are arranged opposite to each other, allowing the first shell 1 and the second shell 2 to be rotated to open or close. In other words, through the cooperation of the rotating structure and the locking structure, the first shell 1 and the second shell 2 can be rotated open or closed.
[0023] In this embodiment, both the first housing 1 and the second housing 2 are cuboid structures, and the first housing 1 and the second housing 2 can be assembled to form a cube structure. It can be understood that the first housing 1 includes a first frame 11 and a first cover plate 12 fixedly connected. One open end of the first frame 11 serves as the open end of the first housing 1, and the opening end is provided with the rotation structure and the locking structure. The first cover plate 12 is fixedly connected to the other open end of the first frame 11 to serve as the closed end of the first housing 1. The second housing 2 includes a second frame 21 and a second cover plate 22 fixedly connected. One open end of the second frame 21 serves as the open end of the second housing 2, and the opening end is correspondingly provided with the rotation structure and the locking structure. The second cover plate 22 is fixedly connected to the other open end of the second frame 21 to serve as the closed end of the second housing 2. In other embodiments, the first housing 1 and the second housing 2 can be set as cylinders or cuboids of other proportions, and the first housing 1 and the second housing 2 can be assembled to form cylinders or cuboids, or other structures.
[0024] It is understood that the rotating structure includes a first connecting block 101 and a mounting hole 102 respectively disposed between the first frame 11 and the second frame 21, with the first connecting block 101 matched and connected within the mounting hole 102. Specifically, the first connecting block 101 has protruding first rotating shafts 1011 on both sides, and the mounting hole 102 has recessed first grooves 1021 rotatably connected to the first rotating shafts 1011 on both sides. In this embodiment, the first connecting block 101 protrudes from one side of the second frame 21, and the mounting hole 102 is recessed from one side of the first frame 11. It is understood that the inner wall of the first frame 11 is provided with a first limiting block 111 corresponding to the mounting hole 102, which is used to restrict the first connecting block 101 to be connected within the mounting hole 102. In other embodiments, the first connecting block 101 may be disposed on the first frame 11, and the mounting hole 102 may be correspondingly disposed on the second frame 21.
[0025] In this embodiment, the locking structure includes a second connecting block 201 and a positioning hole 202 disposed between the first frame 11 and the second frame 21. The second connecting block 201 can be inserted and fixed in the positioning hole 202, so that when the first housing 1 and the second housing 2 are in contact, a relatively stable cubic structure can be formed through the fixed cooperation between the second connecting block 201 and the positioning hole 202. It can be understood that the second connecting block 201 protrudes from the side of the second frame 21 opposite to the first connecting block 101, and the positioning hole 202 is recessed from the side of the first frame 11 opposite to the mounting hole 102. In other embodiments, the second connecting block 201 can be disposed on the first frame 11, and the positioning hole 202 can be correspondingly disposed on the second frame 21. The locking structure can be adjusted to other structures that can be separated and fixed between the first housing 1 and the second housing 2, such as a magnetic structure, a snap-fit structure, etc.
[0026] In this embodiment, a connecting hole 112 is recessed on the remaining sides of the opening end of the first frame 11. The three connecting holes 112 are circumferentially spaced, and a limb member 3 is rotatably connected to each connecting hole 112. Each limb member 3 can rotate to the outside or inside of the first shell 1. It can be understood that when the limb member 3 rotates to the outside of the first shell 1, the limb member 3 can cooperate with the first shell 1 and the second shell 2 to form a toy in the form of a doll or an animal. When the limb member 3 rotates to the inside of the first shell 1, the limb member 3 is basically housed in the cavity formed by the first shell 1 and the second shell 2, so that the first shell 1 and the second shell 2 can be combined to form a block toy with flat sides. In other embodiments, the distribution of the multiple connecting holes 112 can be adjusted according to different variable forms. For example, when the variable form is set as a myriapod, the multiple connecting holes 112 can be arranged opposite to each other on the other two sides of the first frame 11. At the same time, at least one connecting hole 112 can be recessed on the same side of the first frame 11. The number of connecting holes 112 on different sides of the first frame 11 can be the same or different.
[0027] In this embodiment, the limb component 3 includes two upper limb components 31 and one lower limb component 32, which are respectively matched and connected to corresponding connecting holes 112. Specifically, the two upper limb components 31 are respectively connected to two opposite connecting holes 112, and the lower limb component 32 is connected to another connecting hole 112 opposite to the mounting hole 102. The two upper limb components 31 and the lower limb component 32 are designed to mimic the limbs of a doll, so that the magnetic building blocks can be transformed into a doll toy. Each upper limb component 31 has a second rotating shaft 311 protruding from both sides, and each lower limb component 32 has a third rotating shaft 321 protruding from both sides. Each connecting hole 112 has a second groove 1121 recessed on both sides, which can rotatably connect the second rotating shaft 311 or the third rotating shaft 321. It is understood that the inner wall of the first frame 11 is provided with a second limiting block 113 corresponding to each connecting hole 112. The second limiting block 113 is used to restrict the upper limb member 31 and the lower limb member 32 to be connected in the corresponding connecting hole 112. In other embodiments, the number of upper limb members 31 and lower limb members 32 can be adjusted according to different variable forms. For example, the number of upper limb members 31 can be adjusted to zero or more than four, and the number of lower limb members 32 can be adjusted to zero or more than two.
[0028] It is understood that the closed ends of the first shell 1 and the second shell 2 are respectively provided with a plurality of receiving slots 301, and a magnet 302 is provided in each receiving slot 301 so that when the magnetic block is in the form of a block, each side of the magnetic block can be magnetically attracted to other magnetic blocks through the magnet 302.
[0029] Specifically, a first insertion block 114 and a first groove 115 are provided on the other open end of the first frame 11. A second insertion block 121 and a second groove 122 are provided on one side of the first cover plate 12. The second insertion block 121 is inserted and fixed to the first insertion block 114, and the second groove 122 is connected to the first groove 115 to form a receiving groove 301. A third insertion block 211 and a third groove 212 are provided on the other open end of the second frame 21. A fourth insertion block 221 and a fourth groove 222 are provided on one side of the second cover plate 22. The fourth insertion block 221 is inserted and fixed to the third insertion block 211, and the fourth groove 222 is connected to the third groove 212 to form a receiving groove 301. It can be understood that the above structural arrangement facilitates the installation and fixing of magnets 302 in the first housing 1 and the second housing 2, which is beneficial to improving production assembly efficiency.
[0030] In this embodiment, fixing pieces 401 protrude from each side of one of the open ends of the first frame 11 and the second frame 21, and fixing grooves 402 are provided on each side of one side of the first cover plate 12 and the second cover plate 22. The fixing grooves 402 are inserted into and fixedly connected to the fixing pieces 401 in a one-to-one correspondence. It can be understood that the above structural arrangement facilitates further fixing and connecting the first frame 11 and the first cover plate 12, as well as the second frame 21 and the second cover plate 22. In other embodiments, fixing pieces 401 may not be provided on the first frame 11 and the second frame 21, and the fixing grooves 402 may not be provided on the corresponding first cover plate 12 and the second cover plate 22.
[0031] The magnetic building blocks provided in this embodiment can separate the second connecting block 201 and the positioning hole 202 by applying a pulling force to the first housing 1 and the second housing 2, thereby separating the first housing 1 and the second housing 2. Then, the first housing 1 and the second housing 2 can be rotated relative to each other to the open state. Subsequently, the limb 3 can be rotated to connect to the inside or outside of the first housing 1 to change the shape of the magnetic building blocks. Finally, the first housing 1 and the second housing 2 can be rotated relative to each other to the closed state, so that the second connecting block 201 can be inserted and fixed in the positioning hole 202. This allows the magnetic building blocks to be fixedly connected to form a traditional magnetic building block toy for building games, or fixedly connected to form a doll-shaped toy for games.
[0032] For clarity, certain features described in individual embodiments of the present invention may be used in combination in a single embodiment. Furthermore, various features of the present invention described in individual embodiments may also be used individually or in any suitable form in sub-combinations.
