Impact-resistant bolt connecting device

Abstract

The invention relates to an impact-resistant bolt connecting device, comprising a bolt, a tubular bolt sleeve, an elastic pin and an elastic element; wherein the bolt is used for connecting a carriage and a wheel carrier in a dismountable way, one of the carriage and the wheel carrier is provided with a fixed leg, the other is provided with a fixed sleeve for containing the fixed leg, and the fixed leg and the fixed sleeve are all provided with a bolt hole into which the bolt can be inserted transversely; one end of the tubular bolt sleeve is open and is connected with the fixed sleeve, the other end is sealed and is provided with a hole through which the bolt can pass; the elastic pin is arranged in the tubular bolt sleeve and penetrates the bolt along radial direction to be fixed on the bolt; one end of the elastic element is against on the elastic pin, and the other end is against on the other end of the tubular bolt sleeve. The bolt connecting device can be resistant to impact of blown sand and flying stone and can prevent influence caused by strong vibration.

Description

Shock-resistant pin connections technical field The present invention relates to a connection device, more particularly, to a plug connection device capable of resisting impact. Background technique Traditional work lights for railway engineering (for example, light lifting flood lights) are not equipped with pulleys for moving on rails, which is very inconvenient when the work lights need to be moved. At present, the bottom of the frame of some work lights is fixed with a wheel frame, but this integrated structure is inconvenient to install and requires the assistance of others. The vehicle frame and the wheel frame that have a few work lamps can be disassembled mutually, and Fig. 1 has promptly shown a kind of latch connection device in the prior art. In order to meet the waterproof requirements behind the vehicle frame, the vehicle frame and the wheel frame are usually connected to each other through the bolt connection device at the side. On the side of the vehicle ...
