Problems solved by technology
[0002] Automotive interior parts usually use a large number of plastic materials and fast assembly methods. This form is generally due to the limitation of the mold structure on the plastic body that cannot form threaded holes or bottom holes for self-tapping screws, and the plastic parts cannot be tightly connected.

Embodiment Construction
[0020] Such as Figure 1 to Figure 4 Shown is a fastening structure that uses quick-fit nuts to connect parts, including a first part and a second part, the connecting surface 1 of the first part is bonded to the connecting surface 2 of the second part, and the first part The connecting surface 1 of the connecting surface 1 and the connecting surface 2 of the second part are respectively provided with a first screw hole and a second screw hole for the screw 3 to pass through in turn, and the two screw holes are correspondingly arranged to facilitate the passing of the screw 3. The connecting surface 2 of the second part is provided with quick-loading nuts 4 clamped on both sides of the second screw hole, and the screw 3 is locked through the quick-loading nuts 4 .
[0021] A stepped hole 5 is provided on the end wall where the connecting surface 2 of the second part is attached to the connecting surface 1 of the first part, and the stepped hole 5 communicates with the second s...

The invention discloses a fastening structure for connecting parts through a fast-assembly nut. The fastening structure comprises the first part and the second part; the connecting face of the first part is attached to the connecting face of the second part, the connecting face of the first part and the connecting face of the second part are provided with a first screw hole and a second screw hole respectively, the first screw hole and the second screw hole are used for allowing a screw to sequentially penetrate and formed correspondingly, the connecting face of the second part is provided with the fast-assembly nut clamped on the two sides of the second screw hole, and the screw penetrates through the fast-assembly nut to be locked. By adopting the structure, the fastening structure for connecting the parts through the fast-assembly nut has the following advantages that due to the fact that the part assembling structure is fastened through the fast-assembly nut and a self-tapping screw, the phenomenon that a plastic part mould structure is complex due to limitation of the tool operation space is avoided, therefore, the plastic part mould structure is simplified, the development cost is reduced, and the phenomenon that a self-tapping screw hole of a plastic part is prone to slip and crack is avoided, so that part assembly is safer and more reliable; meanwhile, operation is flexible, assembly is diverse, and application is wide.
Description
technical field [0001] The invention relates to a part connection structure, in particular to a fastening structure for connecting parts by using a quick nut. Background technique [0002] Automotive interior parts usually use a large number of plastic materials and fast assembly methods. This form is generally limited by the mold structure on the plastic body and cannot form threaded holes or bottom holes for self-tapping screws, and the plastic parts cannot be tightly connected. . Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a fastening structure that uses fast nuts to connect parts for fast connection and convenient installation and disassembly. [0004] In order to solve the above-mentioned technical problems, the technical solution of the present invention is: a fastening structure that utilizes quick-fit nuts to connect parts, including a first part and a second part, and the connection surface of the f...
