Description

Technical Field

[0001] The utility model relates to the technical field of vehicle fasteners, in particular to a vehicle fastener with a waterproof effect. Background Art

[0002] Plastic fasteners are widely used in vehicle assembly. Vehicle plastic fasteners can effectively reduce the usage amount of bolts, making the disassembly and assembly of connecting components more convenient and greatly reducing the vehicle loading cost.

[0003] Traditional fasteners have a relatively simple plug-in structure. The fasteners are prone to looseness and have a poor sealing effect. In the case of long-term use, there may be water seepage in the vehicle due to the looseness of the fasteners; for example, the patents applied by Shanghai Baolu: a fastening fastener, application number: CN202320598995.0; and application number: CN202220776336.7, named: a plastic fastener; both disclose a fastener applied to vehicle body sheet metal, but neither has a good waterproof effect. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a vehicle fastener with a good waterproof effect.

[0005] To achieve the above purpose, the utility model provides a waterproof vehicle fastener, including a male fastener and a female fastener; a jack is provided in the middle of the female fastener; the male fastener includes a columnar insertion rod and a fastening cap at the end, and the insertion rod is inserted into the jack.

[0006] A circle of elastic skirt is provided at the cap position of the female fastener. After installation, the elastic skirt presses on the surface of the vehicle body sheet metal.

[0007] A circle of limiting edge is provided below the fastening cap of the male fastener. After installation, the fastening cap is installed in the installation groove prefabricated on the vehicle body guard plate, and the bottom plate of the installation groove is limited and fixed between the fastening cap and the limiting edge.

[0008] Further, the female fastener includes two oppositely arranged column feet and two oppositely arranged clamping feet, and the column feet and the clamping feet are arranged alternately around the circumference of the jack; both the clamping feet and the column feet are fixed to the bottom surface of the cap.

[0009] Further, grooves for cooperating with the clamping feet are provided on the surface of the insertion rod.

[0010] The grooves include a pre-installation groove and a positioning groove located above the pre-installation groove, and the pre-installation groove and the positioning groove are transitioned by a raised arc surface.

[0011] Further, when the clamping feet are cooperatively clamped with the pre-installation groove, the shape of the jack between the column feet and the part of the insertion rod inserted between the column feet matches, being narrow at the bottom and wide at the top.

[0012] After the card feet are engaged with the positioning grooves in a snap-fit manner, an interference fit is formed between the narrow part between the wide part of the insertion rod and the column feet, and the column feet are expanded to both sides.

[0013] Furthermore, a guiding groove is provided at the bottom of the column feet, and a guiding rod that mates with the guiding groove is provided at the bottom of the card feet.

[0014] Furthermore, a circular protrusion is provided around the socket of the cap, and an interference fit is formed between the circular protrusion and the end of the insertion rod to achieve sealing.

[0015] Furthermore, the snap cap is formed with a porous structure by scooping out glue.

[0016] Compared with the prior art, the advantages of the present utility model are as follows:

[0017] 1. The present utility model achieves the effect of the first layer of waterproofing through the pressing and fitting between the skirt and the vehicle body sheet metal; in combination with the interference fit between the circular protrusion on the female buckle and the insertion rod, the second layer of waterproofing and sealing effect is achieved, realizing a sufficient waterproofing effect and avoiding water seepage at the sheet metal punching area.

[0018] 2. The male buckle and the female buckle of the present utility model are inserted and mated with each other. The pre-positioning and fixing are achieved through the cooperation of the card feet and the grooves, and the guiding function is achieved through the guiding mechanism at the bottom, enabling the precise positioning between the male buckle and the female buckle.
