Double threaded connection preassembled snap joint

Abstract

The invention relates to a buckle that can be pre-installed in a double-threaded connection, comprising a clamping part and a fixing part, and the clamping part and the fixing part are fixedly connected by threads; the clamping part includes a clamping flange surface, a guide column, a limit card, Threaded claws and elastic limit cards; the upper end of the guide column is fixedly connected with the lower surface of the clamping flange surface; both the limit card and the elastic limit card are arranged at the lower end of the side surface of the guide column; the lower end surface of the limit column A through hole is provided, and a threaded claw is relatively arranged in the through hole; the fixing part is a stud with a nut, and the thread is threadedly connected with the threaded claw. The double-thread connection buckle of this technical solution is pre-installed with the fastened parts in advance by using the thread connection method. The double-thread structure increases the fastening strength between the buckle and the stud. Pre-installation makes assembly convenient and improves assembly efficiency; at the same time, it is simple The assembly constraint requirements of this technical solution can be improved, the utilization rate of the buckle of this technical solution in the whole vehicle can be improved, the degree of generalization and serialization can be improved, and it is more beneficial to cost control.

Description

technical field [0001] The invention belongs to the technical field of clip joints, in particular to a pre-installed clip with double threads. Background technique [0002] There are two fixing methods for buckles in the current technology, one is a single clamping method and the fixed part is clamped and matched, and the other is a self-tapping screw fastening method, but these two methods have their own advantages and disadvantages. The single clamping method is easy to operate, and can quickly connect the fixed parts through snaps, but this type of clamping method is poor in gravity, and the buckles are easy to fall out of the fixed parts. [0003] Using self-tapping screw fastening method, the buckle and the fixed part are firmly connected. Unless the buckle is damaged, the buckle will not be separated from the fixed part. However, when fixing, the buckle and the fixed part are movable. , the position of the fixed part needs to be fixed, and special tools are required f...
