An anti-loosening secondary pre-tightening bolt

Abstract

The invention discloses an anti-loosening secondary pre-tightening bolt, which belongs to the technical field of bolts. The solution strengthens the tightening nut, workpiece and screw through the limit fixing between the limit rod and the limit groove in the positioning anti-loosening mechanism. The locking and fixing between them improves the tightness of the connection between the three, and when the workpiece vibrates, multiple friction balls in the absorption and loosening mechanism collide and rub against each other, generating static electricity, and attracting the magnetically insulating powder to gather upwards. The magnetic insulating powder on both sides becomes loose and dispersed, and the movable rod is attracted by the magnet block to push the pressing plate against the screw, and cooperate with the hard transition of the buffer fluid to dissipate the vibration force and reduce looseness. The limit engagement between the workpieces exerts an upward pressing force, which further strengthens the connection, enhances the anti-loosening effect, improves the stability, and enhances its use effect.

Description

technical field [0001] The invention relates to the technical field of bolts, and more particularly, to an anti-loosening secondary pre-tightening bolt. Background technique [0002] A bolt is a cylindrical and threaded fastening mechanical part equipped with a nut. It is often used in the fixed connection between various parts. Bolts are widely used in electronic products, digital products, power equipment, electromechanical products and other industries. There are different types of bolts, according to the shape of the head, there are square head, round head, countersunk head, hexagonal head and so on. [0003] At present, after the parts of various parts of the mechanical equipment are processed, these equipment parts are then connected, assembled and fixed by bolts. However, during the long-term use of the mechanical equipment, the equipment parts are affected by vibration, which is easy to cause the bolts to shake, resulting in nuts. Sliding wire, resulting in loosenin...

[0003] At present, after the parts of each part of the mechanical equipment are processed, these equipment parts are then connected, assembled and fixed by bolts. However, during the long-term use of the mechanical equipment, the equipment parts are affected by vibration, which easily causes the bolts to shake, causing the nuts to Slipping the wire, which leads to loosening and affects the stability of the threaded connection
