Abstract

The invention relates to an anti-falling device for a bolt. The anti-falling device comprises a substrate, a bolt, a fixing frame and a clamping plate, wherein the bolt is connected to the substrate; the fixing frame is fixedly connected with the bolt; the clamping plate is connected with the fixing frame; and the fixing frame and the clamping plate are positioned on both sides of the substrate respectively. According to the device disclosed by the invention, the fixing frame which is fixedly connected with the bolt and the clamping plate which is connected with the fixing frame are arranged on both sides of the substrate, so that the bolt is prevented from falling unexpectedly after a nut falls off.

Description

technical field [0001] The invention belongs to the field of connectors, and in particular relates to a bolt drop preventing device. Background technique [0002] In industrial production or daily life, it is often necessary to fix two objects together. Generally, bolts and nuts are used to connect the two objects. And nuts are often easy to fall. When these two objects are in a special position (such as a high-altitude environment), the falling of bolts and nuts will cause safety hazards or cause other adverse problems. [0003] Zhou Mingjie et al. applied for a nut drop prevention device in 1999, which included nuts and bolts that fixedly connect the first object and the second object together, an anti-drop sheet for accommodating the nut on the first object, The anti-fall sheet includes an interference fit portion that is interference fit with the first object and a clearance fit portion that is clearance fit with the first object. During assembly, the interference fit ...
