Problems solved by technology

[0005] The purpose of the present invention is to provide a bolt with anti-seismic function. Through the design of the bolt body, anti-seismic assembly, transmission assembly and fastening assembly, it solves the problem that the existing anti-seismic bolt can only achieve anti-seismic on one side of the bolt. It is impossible to meet the anti-seismic fixation on both sides of the bolt at the same time, so that the anti-seismic effect of the bolt is poor. The problem of bolt installation efficiency

Abstract

The invention discloses a bolt with an anti-seismic function, and relates to the technical field of bolts. A limiting hole channel communicating with a first cavity is formed in the peripheral side face of a bolt body; an anti-seismic elastic piece is arranged in the first cavity, a connecting disc is fixed to one end of the anti-seismic elastic piece, a supporting seat in sliding fit with the limiting hole channel is fixed to the peripheral side face of the connecting disc, and an anti-seismic pad is fixed to the surface of the supporting seat. A plurality of positioning grooves are formed in the surface of the bolt body, and anti-seismic assemblies in sliding fit with the positioning grooves are arranged in the second cavity. A transmission assembly engaged with the anti-seismic assembly is fixed in the second cavity. A fastening assembly matched with the sliding way is fixed to the surface of the connecting disc and meshed with the transmission assembly. Through the design of the fastening assembly, the anti-seismic assembly, the transmission assembly and the anti-seismic pad, in the nut screwing process, opposite movement of the anti-seismic pad and the anti-seismic assembly can be achieved, then elastic anti-seismic of the two sides of a connected piece is achieved at the same time, and the anti-seismic effect of the bolt is improved.

Description

Technical field [0001] The present invention belongs to the field of bolt technology, in particular to a bolt having a seismic function. Background [0002] When it is necessary to fix the two connected parts, the bolt connection is often used, but when the connected parts vibrate due to external forces, the bolts are often loosened, which in turn affects the stability between the two connectors. [0003] After searching, the Chinese invention patent number is CN111706589B of a kind of shock-resistant bolt, including the screw body and the outer fixing ring, the outer fixing ring includes a toroidal tube and a horizontal plate set in the annular tube, the horizontal plate is provided with a threaded hole for the screw body to pass through, the inner pipe body of the annular tube is provided with an internal thread, and a threaded hole for the screw body is formed on the top of the connecting part one and a ring groove for the annular tube, and the annular pipe is connected with t...
