Abstract

The invention belongs to the technical field of mechanical parts, and discloses a high-strength fastener suitable for automobiles. The high-strength fastener suitable for automobiles comprises a screw rod and a screw cap, wherein the screw rod and the screw cap are detachably connected, both the screw rod and the screw cap are provided with insertion holes, the screw rod and the screw cap are connected through an insertion pin, and the insertion pin is inserted into the insertion holes. The screw rod and the screw cap are fixed by inserting the insertion pin into the insertion holes, and the screw rod and the screw cap are inserted and fixed through the insertion pin during normal use; and when the screw rod is damaged, the insertion pin is detached from the insertion holes, so that the screw rod is separated from the screw cap, and the screw cap can be reused. The screw cap can be recycled, so that the manufacturing cost of the high-strength fastener is saved.

Description

technical field [0001] The present application relates to the technical field of mechanical accessories, and more specifically, relates to a high-strength fastener suitable for automobiles. Background technique [0002] High-strength fastener connection is a superior steel structure connection, which has the advantages of good force resistance, fatigue resistance, and not easy to loosen, so it is widely used in the field of automobile assembly. [0003] The fastener is usually composed of a screw and a nut connected to one end of the screw. The screw plays the role of connecting and bearing the load. The service life of the screw plays a decisive role in the service life of the bolt. The role of the circumferential fixed connection with the tool, on the other hand, is to limit the screw-in depth of the screw. Compared with the bolts that play the role of connection and load bearing, the service life of the nut is much longer. [0004] At present, high-strength fasteners are...
