A fall-proof bolt for narrow areas

Abstract

The invention discloses a fall-off prevention bolt used in a narrow area, and relates to the technical field of fasteners. The present invention includes screws, nuts, clamps and reinforcements. The screws include a screw part and a nut part. The nut is arranged on the screw part and threadedly connected with the screw part. Channels are opened on the opposite sides of the side of the screw part. One end passes through the nut part, the clip is fixed on the screw part, and one side of the clip is attached to the end surface of the nut away from the nut part. The present invention can limit the position of the nut on the screw part by setting a clamp on the screw part and a rubber pad between the clamp and the screw part, and can avoid the problem of loosening and falling off of the nut. The space between the clamp and the nut can be reinforced to further limit the position of the nut, and at the same time, it can avoid the problems that the nut is easy to fall off and the clamp is easy to shift due to high-frequency vibration, which solves the existing anti-falling ability of the bolt Insufficient problem.

Description

technical field [0001] The invention belongs to the technical field of fasteners, in particular to a fall-off prevention bolt used in a narrow area. Background technique [0002] For the bolts used in larger and more frequent positions, the nuts will rotate slowly after long-term use, which will lead to the problem that the nuts are easy to loosen and fall off, thus affecting the fastening and safety of the fixed position. Anti-loosening measures can use wedge-shaped gaskets, welded nuts, or the method of opening holes on the screw part to pass through steel wires for anti-loosening. However, this type of anti-falling method still has the following disadvantages: [0003] 1. The method of using wedge-shaped gaskets still has the problem of insufficient anti-loosening effect, and the anti-loosening effect is not good. [0004] 2. The method of using welding nuts will reduce the construction efficiency, and for the use of narrow areas, the welding head of the welding equipmen...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide an anti-falling bolt for narrow areas. By setting a clamp on the screw part and setting a rubber pad between the clamp and the screw part, the position of the nut on the screw part can be restricted. It can avoid the problem of loosening and falling off of the nut. At the same time, the reinforcing piece can be inserted to reinforce the clamp and the nut part, further restricting the position of the nut, and at the same time, it can avoid the nut easy to fall off and the clamp caused by high-frequency vibration The problem of easy displacement solves the problem of insufficient anti-falling ability of existing bolts
