[0002] A buckle structure is a structure of an institution for the embedded connection or overall locking of one part to another part. Generally speaking, a buckle structure consists of a positioning part and a fastening part. The function of the positioning part is to guide the buckle to reach the installation position smoothly, correctly and quickly during installation. And the function of the fastening part is that: the detachable fastening part is usually designed so that when a certain separation force is applied, the buckle will come off and the two connecting parts will separate. It is usually used for the connection of plastic parts, and its material is usually composed of plastic materials with a certain flexibility. The biggest feature of the buckle connection is that it is convenient for installation and disassembly, and can be disassembled without tools, and is mostly applicable to decoration scenarios.

[0003] However, some buckles do not need to be disassembled, which requires a non-detachable buckle structure that is convenient for installation and difficult to disassemble. However, the existing non-detachable buckle structures often adopt a semi-circular arc structure. In the initial state of the buckle, the pressure received by the fastening part and the force-receiving surface of the semi-circular tangent point of the positioning part are in a vertical relationship, and the decomposition force towards the arc surface is insufficient and it is not easy to buckle. In addition, even if the upper and lower buckles are firm after buckling, the left and right buckles are not firm.
