Description

Technical Field

[0001] This utility model belongs to the field of building block technology, specifically relating to a disassembly-friendly children's building block. Background Technology

[0002] Building block toys are toys made by stacking and assembling multiple building blocks of different sizes and shapes. Building blocks have interlocking protrusions and recesses on their surfaces, allowing multiple blocks to be stacked together to form various shapes. Furthermore, because building blocks come in different colors and shapes, they can be repeatedly assembled into endlessly varied shapes, making them very popular. Currently, building block toys focus more on the diversity of the assembled shapes, without considering the need to disassemble the blocks before creating different shapes. For example, some building blocks are very tightly connected after assembly, making disassembly difficult, time-consuming, and laborious. Furthermore, children may pose safety hazards if they try to disassemble blocks by using their fingers or teeth.

[0003] To address the current issue of disassembling building blocks, existing products primarily employ the design and development of related disassembly tools. These tools mainly fall into two categories: dedicated tools and universal disassembly devices. Dedicated tools are complex in structure, cumbersome to operate, and time-consuming and laborious to use with a large number of blocks. Furthermore, some tools have limited compatibility with specific block sizes. The latter increases the number of tools available, requiring children to learn how to use them. This increases the cost of building block toys and adds complexity to operation due to the learning process. Children, being less adept at tidying up and caring for toys, are prone to losing or damaging these tools, rendering the toys unusable. Purchasing additional tools further increases costs, and the time-consuming and laborious disassembly process results in a poor user experience, potentially causing negative emotions in children.

[0004] Therefore, there is a need for a type of easy-to-disassemble children's building block that is practical and easy to assemble. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a disassembly-friendly children's building block, which solves the problem that the existing technology of disassembling building blocks by means of external tools is time-consuming and laborious for children to learn how to operate the tools, and the tools are easy to lose, and the cost of repurchasing them increases.

[0006] One embodiment of this utility model provides a detachable children's building block for use as a building block. The detachable children's building block includes: a building block block, a rotating groove is formed on the top of one side wall of the building block block, a first magnetic block is fixedly provided on the lower inner wall of the rotating groove, a connecting shaft is fixedly provided on the upper inner wall of the rotating groove, and a disassembly assembly is movably sleeved on the outer side of the connecting shaft. The disassembly assembly includes a docking plate, a connecting cylinder, a spiral spring, and a second magnetic block. A connecting cylinder is fixedly provided on the upper end of one side wall of the docking plate, a spiral spring is fixedly provided on the inner side of the connecting cylinder, the spiral spring is fixedly sleeved on the outer side of the connecting shaft, and a second magnetic block is fixedly provided on the lower end of one side wall of the docking plate.

[0007] In one embodiment, a disassembly groove is provided on the top of the other side wall of the building block.

[0008] In one embodiment, the bottom of the rotating groove is provided with an arc-shaped groove.

[0009] In one embodiment, the bottom of the mating plate is provided with a fitting slope, which is located inside the arc-shaped groove.

[0010] In one embodiment, the top surface of the mating plate is flush with the top surface of the building block.

[0011] In one embodiment, the left side of the docking plate is flush with the left side of the block.

[0012] In one embodiment, the length of the docking plate is adapted to the length of the rotating groove.

[0013] In one embodiment, the corners of the docking plate and the corners of the rotating groove are both rounded.

[0014] In one embodiment, the disassembly groove is crescent-shaped.

[0015] In one embodiment, the corners of the disassembly groove are rounded.

[0016] The easily detachable children's building blocks provided in the above embodiments have the following beneficial effects:

[0017] 1. Using the set building blocks and disassembly components, rotating grooves are made at the side edges of the building blocks. A connecting shaft movably engages the docking plate of the disassembly components inside the rotating grooves, ensuring the outer side of the docking plate aligns with the outer side of the building blocks. This maintains the shape of the building blocks when viewed from the outside, avoiding any impact on the final assembled appearance. The upper end of the docking plate is connected to the connecting shaft via a spiral spring. The spring force rotates the docking plate outwards. Since the lower end of the docking plate engages inside the rotating groove, it is stably engaged within the groove. A second magnetic block is installed, and a first magnetic block is installed inside the rotating groove. After a child assembles multiple building blocks, if disassembly is required, no tools are needed. Simply press the connecting plate to make it rotate inward into the rotating groove. After rotation, the second magnetic block and the first magnetic block are attracted to each other and limit the movement. This creates a groove on the top of the side of the building block after the connecting plate rotates, allowing the child to apply pressure with their fingers to easily disassemble the building block. After disassembly, press the raised top of the connecting plate to reset it. This allows for convenient disassembly of the assembled building blocks without using external tools or changing the general shape of the blocks.

[0018] 2. By designing a disassembly groove, for some building blocks where the desired shape after assembly is not important, i.e., the focus is on assembly rather than the final appearance, a disassembly groove is provided on the upper side of the building block. After the building block is assembled, children can easily disassemble the building block by placing their fingers inside the disassembly groove. The disassembly groove is crescent-shaped to better fit the shape of a child's fingertips, making disassembly easier. At the same time, the edges of the disassembly groove are rounded to prevent children's fingers from being injured due to force. Attached Figure Description

[0029] One embodiment of this utility model provides a detachable children's building block, see reference. Figure 2 and Figure 3As shown, specifically, it includes building block 1, which is a common children's building block. Its assembly principle is existing technology, so it is not described in detail. A rotating groove 11 is opened on the top of one side wall of building block 1. A first magnetic block 13 is fixedly installed on the lower inner wall of the rotating groove 11. A connecting shaft 14 is fixedly installed on the upper inner wall of the rotating groove 11. A disassembly assembly 2 is movably sleeved on the outer side of the connecting shaft 14. The disassembly assembly 2 includes a docking plate 21, a connecting cylinder 22, a spiral spring 23, and a second magnetic block 24. A connecting cylinder 22 is fixedly installed on the upper end of one side wall of the docking plate 21. A spiral spring 23 is fixedly installed on the inner side of the connecting cylinder 22. The spiral spring 23 is fixedly sleeved. Connected to the outside of the connecting shaft 14, the spiral spring 23 applies a force that rotates outwards to the docking plate 21. A second magnet 24 is fixedly provided at the lower end of one side wall of the docking plate 21. An arc-shaped groove 12 is provided at the bottom of the rotating groove 11, and the arc-shaped groove 12 is set according to the rotation path of the bottom of the docking plate 21. The bottom of the docking plate 21 is provided with a fitting inclined surface 25, which is located inside the arc-shaped groove 12. The lower end of the docking plate 21 abuts against the inner side of the rotating groove 11 by the engagement of the arc-shaped groove 12 with the fitting inclined surface 25. The top surface of the docking plate 21 is flush with the top surface of the block 1. The left side surface of the docking plate 21 is flush with the left side surface of the block 1. The length of the mating plate 21 matches the length of the rotating groove 11, ensuring that the shape of the building block 1 remains largely unchanged after the mating plate 21 is installed inside the rotating groove 11. The edges and corners of both the mating plate 21 and the rotating groove 11 are rounded to prevent children's fingers from being scratched. For building blocks where the shape after assembly is important, this design includes a rotating groove 11 on the top side of the building block 1. The mating plate 21 is movably engaged inside the rotating groove 11. When children need to disassemble the building block 1 after assembly, they can press the mating plate 21 with their fingers to rotate it inwards into the rotating groove 11, allowing the second magnetic block 24 to... After being moved, it adheres to the first magnetic block 13, thereby creating a groove on the block 1 due to the rotation of the docking plate 21. This allows children to hold the block 1 with their fingers and easily apply pressure to disassemble it without the need for external tools. After disassembly, the top of the docking plate 21 is lifted due to rotation. Pressing the top of the docking plate 21 causes it to return to its original position under the action of the spiral spring 23, thus restoring the shape of the block 1. This facilitates disassembly without altering the shape of the block, improving its practicality. Furthermore, the disassembly component 2 is not limited to being installed on blocks of the type 1 in this design; it can be installed according to actual needs, with the same principle.

[0030] In one embodiment, reference Figure 1 and Figure 4As shown, specifically, a disassembly groove 3 is provided on the top of the other side wall of the building block 1. The disassembly groove 3 can be separated from the disassembly component 2 and used on different building blocks 1 in actual use. The disassembly groove 3 is crescent-shaped, which fits the shape of a child's fingertips and makes disassembly easier. The edges and corners of the disassembly groove 3 are rounded. For some building blocks that focus on the assembly process rather than the appearance after assembly, the disassembly groove 3 on the top side of the building block 1 allows children to easily disassemble the building blocks by placing the collection clip inside the disassembly groove 3. At the same time, the crescent-shaped groove can also be used as a feature of the building block's appearance, which can increase the fun of the building blocks to a certain extent.

[0031] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
