[0002] The building block toy is loved by players because it can be combined into various shapes according to imagination by means of plug-in structure. The plug-in structure of the building block toy usually adopts plug-in columns and plug-in holes on the building block, and the plug-in columns are inserted into the plug-in holes when connected; or plug-in holes are opened on the building block, and two building blocks are connected through independent plug-in columns; of course, other toys also often need to plug in some parts, and most of them are plug-in columns and plug-in holes. The current plug-in columns and plug-in holes generally adopt the structure disclosed in the publication No. CN206809773U, a limiting flange and a U-shaped groove are opened on the plug-in column, the ends of the U-shaped groove on both sides are flexed inward when plugging, the U-shaped groove is compressed, the ends of the plug-in column enter the plug-in hole, and the limiting flange clamps the edge of the plug-in hole. Although this plug-in structure can tightly connect the building blocks, it is often difficult to pull out when disassembling, and it can also cause wear and tear to the plug-in part, which is prone to breakage after repeated plugging and unplugging, and has a short service life. SUMMARY

[0003] The utility model solves the technical problem to provide a toy plug-in structure, which is convenient to connect and disassemble, does not need to be pulled out with great force when disassembling, does not cause damage to the plug-in part, and can effectively prolong the service life of the toy.

[0004] In order to solve the above technical problems, the technical scheme adopted is as follows:

[0005] A toy plug-in structure, comprising a basic connection unit, the front end of the basic connection unit is provided with a plug-in column, and the rear end of the basic connection unit is provided with a plug-in hole matched with the plug-in column, characterized in that: the plug-in column is in a cylindrical or circular truncated cone shape; at least one inward recessed positioning groove is arranged on the side wall of the plug-in column, the side walls on both sides of the positioning groove are respectively provided with first inclined surfaces gradually inclined inward from the end to the middle; at least one outward protruding positioning block is arranged on the side wall of the plug-in hole, the number of the positioning blocks is the same as that of the positioning grooves and corresponds one by one, the inner wall surface of the positioning block gradually inclines inward from back to front, the side walls on both sides of the positioning block are respectively provided with second inclined surfaces gradually inclined inward from the end to the middle, and the positions of the second inclined surfaces correspond to those of the first inclined surfaces, and the second inclined surfaces and the first inclined surfaces form a continuous sliding surface.

[0006] The toy plug-in structure can be applied to various toys (i.e. basic connection units such as various building blocks) that need to be combined at will. The plug-in column is inserted into the corresponding plug-in hole to be connected. When connected, the positioning groove is aligned with the position of the positioning block and then inserted. When inserted, the plug-in column first pushes the positioning block apart through the inner wall surface of the positioning block, and after the positioning groove corresponds to the positioning block, the positioning block can be clamped into the corresponding positioning groove and the connection is completed, so that the two basic connection units cannot be separated or rotated relative to each other. When disassembled, only a slight force is needed to rotate the two basic connection units, so that the second inclined surface on the positioning block can pass over the first inclined surface on the positioning groove, so that the positioning block and the positioning groove are misaligned, and the positioning block is pushed outward by the wall surface of the plug-in column. At this time, the plug-in column can be smoothly pulled out of the plug-in hole. The toy plug-in structure adopts a "double-inclined-surface self-unlocking" design, and the connection and disassembly are relatively convenient. When disassembled, only the rotation of the basic connection unit can misalign the positioning block and the positioning groove, so that the plug-in column can be smoothly pulled out. The pulling-out process is smooth and does not require brute force. Only the positioning block will deform to the smallest extent when being pushed outward, and is not easy to damage, which can effectively prolong the service life of the toy, and the plug-in service life is increased from 500 times to 2000 times.

By setting the third inclined surface and the fourth inclined surface, the third inclined surface and the fourth inclined surface can also form a continuous sliding surface. When disassembled, the third inclined surface and the fourth inclined surface can make the basic connection unit rotate more smoothly and reduce wear. At the same time, the third inclined surface and the fourth inclined surface can also play a positioning role when plugged in.

With this arrangement, when disassembling, it can be ensured that no matter where the rotation is performed, it can be relatively easy, and the stress is more uniform.
