Abstract

The invention discloses a bolt with a looseness alarm function and belongs to the technical field of fasteners. The bolt with the looseness alarm function comprises an outer hexagonal bolt body, the outer hexagonal bolt body is provided with a threaded extension portion and a hexagonal head end portion which are sequentially arranged, the hexagonal head end portion is provided with hydraulic passages axially extending along the hexagonal head end portion, the hydraulic passages include the first hydraulic passage close to one side of the threaded extension portion and the second hydraulic passage distant from the side of the threaded extension portion, the second hydraulic passage is communicated with the first hydraulic passage, an end of the first hydraulic passage, on one side of the threaded extension portion, is provided with a first plunger, the first plunger extends out of the hexagonal head end portion, the second hydraulic passage is provided with a second plunger inside, and hydraulic oil is filled between the second plunger and the first plunger. The hexagonal head end, distant from one side of the threaded extension portion, is provided with an alarm circuit comprising a direct-current power source, an alarm lamp, a sound alarm and a knife switch, and the second plunger is connected with the knife switch. When the bolt is loosened, the alarm can be sent in time, and labor cost is reduced.

Description

technical field [0001] The invention relates to a bolt, more particularly to a loosening alarm bolt, and belongs to the technical field of fasteners. Background technique [0002] In the field of machinery manufacturing, there are three commonly used anti-loosening methods for bolt anti-loosening: friction anti-loosening, mechanical anti-loosening and permanent anti-loosening. [0003] Among them, mechanical anti-loosening and friction anti-loosening are called detachable anti-loosening, and permanent anti-loosening is called non-detachable anti-loosening. Commonly used permanent anti-loosening methods include: spot welding, riveting, bonding, etc. Most of these methods will destroy threaded fasteners during disassembly and cannot be reused; common frictional anti-loosening methods include: using gaskets, self-locking nuts and double nuts etc.; common mechanical anti-loosening methods: using cotter pins, stop washers and string wire ropes, etc. Among these three anti-loose...
