A kind of anti-loosening bolt

Abstract

The invention relates to an anti-loosening bolt, which includes a bolt cap and a threaded bolt post. Several pairs of symmetrical grooves are opened on the side wall of the bolt post, and right-angled triangle limit plates are arranged in the grooves. The right-angled triangle The right-angled end of the limiting plate faces the bolt cap, and the smallest acute-angled end faces the end of the bolt column away from the bolt cap; a return spring is arranged between the right-angled triangle limiting plate and the bottom surface of the groove, and when the returning spring is not compressed, the right-angled triangle The limit plate protrudes from the side wall of the bolt, and when the return spring is compressed, the right-angled triangle limit plate enters the groove; the advantage is that the fastening glue is simple to glue, and the bolt can be realized by simply screwing the bolt normally. Fastening and gluing will not cause harm to the hand, and the glue will not drip outside the screw hole; the glue is evenly applied, and during the screwing process of the bolt, the pressure plate slowly squeezes the capsule, so that the glue is slowly squeezed out, and With the rotation of the bolt, it is automatically applied; when leaving the factory, the glue is stored in the bolt, and the glue will not be reduced due to packaging and transportation vibration.

Description

technical field [0001] The invention relates to the technical field of fasteners, in particular to an anti-loosening bolt. Background technique [0002] In large equipment, in order to prevent the bolt fasteners from loosening due to vibration, installers usually apply glue on the bolts, but because the application process is done manually, the installation efficiency of the equipment is reduced, and the glue has certain chemical hazards , the glue attached to the hands will have an impact on the health of the installer. [0003] In order to solve this defect, many bolt fasteners have been automatically glued when they leave the factory. Although it can solve the defects caused by manual glue application, after the bolts with automatic glue coating are packaged and transported, the glue on the surface of the bolt will be reduced. There will be unavoidable wear and tear, resulting in a decrease in the fastening effect of the glue. [0004] Based on this, this case is brough...
