Anti-loosening bolt

Abstract

The invention belongs to the field of bolts and particularly discloses an anti-loosening bolt. The anti-loosening bolt comprises a screw rod and a screw cap. A locking rod is a threaded rod, threaded holes matched with the locking rod are formed in the screw cap and the screw rod, a first cavity is formed in the screw rod, a first plastic membrane is arranged in the first cavity, the first plastic membrane divides the first cavity into a first raw material cavity and a mixing cavity, glue A is arranged in the first raw material cavity, a second cavity is formed in the locking rod, a second plastic membrane is arranged in the second cavity, the second plastic membrane divides the second cavity into a second raw material cavity and a discharge cavity, glue B is arranged in the second raw material cavity, the discharge cavity is funnel-shaped, a sealing ball for sealing the discharge cavity is arranged in the discharge cavity, a first pricking needle for pricking the first plastic membrane and a second pricking needle for pricking the second plastic membrane are arranged on the sealing ball, a glue discharge hole is formed in the screw rod, and is communicated with the mixing cavity. According to the scheme, double-fixation by the thread and viscose glue is realized, so that the stability and the safety of equipment can be improved to a great extent.

Description

technical field [0001] The invention belongs to the field of bolts. Background technique [0002] With the rapid development of my country's economy, fasteners have not only been widely used in advanced fields such as electronic products, machinery, computers, mobile phones, and automobiles. Screws are a commonly used connector, because the vibration of mechanical equipment causes the screws to fall off and affect the normal operation of the equipment, seriously affecting the safety and stability of the equipment. [0003] On February 24, 1999, China Southwest Airlines TY154M / B-2622 aircraft crashed into the ground in Wenzhou area while carrying out the mission of flight SZ4509 from Chengdu to Wenzhou. The aircraft shattered and disintegrated, killing all 61 people on board. Because the nuts were unscrewed and the connecting bolts fell off during the flight of the aircraft, the control of the pitch channel of the aircraft failed and the accident occurred. Therefore, there ...
