Abstract

The invention relates to a modified anti-loosening bolt. The modified anti-loosening bolt comprises a bolt head and a threaded rod. Two sides of the threaded rod are provided with grooves for placing anti-dropping devices including movable plates and elastic parts. One end of each elastic part is fixed into a groove and the other end is connected to the upper end of each movable plate. The lower end of each movable plate is movably fixed in the joint between each groove and the threaded rod. The bottom of the threaded rod is provided with an empty groove, the interior of which is connected with an inner rod through each elastic part. The upper end of the threaded rod is in threaded connection with a movable gasket, the bottom of which is provided with an anti-skidding layer. The modified anti-loosening bolt has following advantages: under the effect of elastic parts, the movable plates have outward tension and the bolt is not easily loosened; due to the movable gasket of the threaded rod, the ant-skidding layer at the bottom of the movable gasket has an effective anti-skidding effect; and due to threaded and movable connection between the movable gasket and the threaded rod, the movable gasket can freely move up and down to adjust the length that the threaded rod is not in an object to be fixed.

Description

technical field [0001] The invention relates to a bolt, in particular to an improved anti-loosening bolt, which belongs to the field of standard part manufacturing. Background technique [0002] In industrial production or daily life, it is often necessary to fixedly connect two objects together, and bolts are usually used to connect the two objects together. However, due to the existence of external factors such as subsequent vibrations and collisions, the bolts are often easily loosened from the fixed objects, resulting in safety hazards. Therefore, a new technical solution should be provided to solve the above problems. Contents of the invention [0003] The object of the present invention is to provide an improved anti-loosening bolt. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: an improved anti-loosening bolt, including a bolt head and a threaded rod, grooves for placing anti-dropping devices are arranged...
