Buckle assembly

Abstract

The invention provides a buckle assembly and belongs to the field of mounting and fastening structures. The buckle assembly comprises a secondary buckle and a primary buckle, wherein the secondary buckle and the primary buckle can be connected in a clamped mode. The secondary buckle comprises a pressing part, a guide post and a limiting structure. The limiting structure is arranged at the insertion end of the guide post. The pressing part is arranged at the other end of the guide post. The primary buckle comprises a primary buckle base, a guide part and a step clamping part arranged on the side edge of the guide part. The guide part is arranged on the primary buckle base. The primary buckle base is provided with a through hole for the secondary buckle to be inserted in. The guide part is provided with a hollow portion. The through hole corresponds to the hollow portion. The secondary buckle is connected in the hollow portion in a clamped mode. The buckle assembly has the beneficial effects of being capable of being used repeatedly, low in cost, not liable to generate permanent deformation, suitable for fastening base materials of different thicknesses, reliable in performance and easy to dismount.

Description

technical field [0001] The invention relates to an installation and fastening structure, in particular to a snap fitting. Background technique [0002] The existing structure and installation method: the buckle and sub-buckle are mostly thread structure: the mold structure is complex, the force required for the movement and reset of the sub-buckle is very large, and the installation and disassembly are poor; It produces permanent deformation and cannot be reused; the range of clamping thickness is small. [0003] The prior art has published a buckle with the patent number: 200820055290.X, which includes a sub-buckle and a female buckle. The female buckle is two detachable legs. When fixing the product, the fastening surface between the female buckle and the product is smooth. In addition, the inner surface of the expansion structure of the female buckle is used as a guide, and the two legs are in a long-term expansion state during installation, which is prone to permanent d...

[0002] The existing structure and installation method: the buckle and sub-buckle are mostly thread structure: the mold structure is complex, the force required for the movement and reset of the sub-buckle is very large, and the installation and disassembly are poor; Produces permanent deformation and cannot be reused; the range of clamping thickness is small

[0003] The prior art has published a buckle with the patent number: 200820055290.X, which includes a sub-buckle and a female buckle. The female buckle is two detachable legs. When fixing the product, the fastening surface between the female buckle and the product is smooth. The surface of the female buckle is easy to fall off and the installation is not firm; moreover, the inner surface of the female buckle expands and opens the structure as a guide, and the two legs are in a state of long-term expansion during installation, which is prone to permanent deformation and is not conducive to repeated use.

[0004] At the same time, the undercut structure is installed on the sub-button, and the inner surface of the female buckle is also a smooth structure. When encountering external force collision or shaking, it is easy to squeeze the feet, causing the sub-button to shrink inwardly, so that the sub-button The connection with the female buckle is loose, resulting in the situation that it cannot be fastened
