Bolt convenient to use

Abstract

The invention discloses an easy-to-use bolt, which comprises an outer hexagonal prism, a hexagonal cavity, an inner hexagonal prism, a chute, a bump, a screw, a mounting hole, a slider, a spring, an oil injection hole and a through hole. The prism is provided with a hexagonal cavity that is coaxial with the outer hexagonal prism and runs through the outer hexagonal prism. The inner side of the hexagonal cavity is slidably provided with an inner hexagonal prism adapted to the shape of the hexagonal prism. The outer side of the inner hexagonal prism Two of the opposite sides of the wall are provided with a vertically arranged chute, and two of the opposite sides of the inner side wall of the hexagonal cavity are fixed with protrusions, and the protrusions are correspondingly clamped in the chute , the lower part of the inner hexagonal prism is fixedly connected with a screw rod. Compared with the prior art, the outer width of the nut can be changed to facilitate tightening or loosening the nut, effectively prevent the bolt from loosening, and facilitate oiling and maintenance of the bolt. The structure is simple, the use is convenient, and the application is convenient.

Description

【Technical field】 [0001] The invention relates to the technical field of standard parts, in particular to an easy-to-use bolt. 【Background technique】 [0002] A bolt is a mechanical part, a cylindrical threaded fastener with a nut. A type of fastener consisting of a head and a screw with a cylindrical body with external threads, which needs to be matched with a nut to fasten and connect two parts with through holes. This connection form is called bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection. Most of the existing bolt nuts are hexagonal, and their specifications are fixed. Only an adapted wrench can be used to tighten or loosen it, but in the actual use of the bolt, sometimes an adjustable wrench or a suitable dead wrench cannot be found temporarily, resulting in the inability to tighten or loosen the bolt. The adaptability is not strong, which brings a lot of trouble to the use of...

AI Technical Summary

Problems solved by technology

If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection. Most of the existing bolt nuts are hexagonal, and their specifications are fixed. Only an adapted wrench can be used to tighten or loosen it, but in the actual use of the bolt, sometimes an adjustable wrench or a suitable dead wrench cannot be found temporarily, resulting in the inability to tighten or loosen the bolt. The adaptability is not strong, which brings a lot of trouble to the use of bolts. In addition, when the existing bolts work in a vibrating environment for a long time, they are easy to loosen due to vibration and affect the normal use of the bolts. The existing bolts are inconvenient. Carry out oiling and maintenance on the bolts. When the bolts need to be oiled and maintained, it is very troublesome to unscrew the bolts, oil the bolts and then re-tighten the bolts.
