A locking mechanism for mechanical bolts and nuts

Abstract

A locking mechanism for mechanical bolts and nuts. A circular pit is made at the center of the bottom surface of the locking nut, and radial grooves are made around the circular pit. The depth of the circular pit is slightly larger than that of the radial groove. Depth; a keyway is made on the upper plane of the fastening nut, and the width of the keyway is equal to that of the radial groove; the width of the spring pin is equal to the width of the radial groove and the keyway, and the head of the spring pin has a U-shaped protrusion; use a tight The fastening nut is connected with the bolt, and a fast connection relationship is formed between the bolt and the fastening nut. Install the fastening nut on the bolt protruding from the upper part of the fastening nut, continue to tighten the fastening nut, and make the radial groove and the fastening nut Align the keyway on the top of the fixing nut, make the locking nut in a tightened state, put the U-shaped protrusion of the head of the spring pin upward and inward, and insert the spring pin into the groove and keyway that are aligned with each other until the spring pin is The U-shaped projection of the head is engaged in the circular recess on the bottom surface of the lock nut.

Description

technical field [0001] The invention relates to a locking mechanism for bolts and nuts, in particular to a locking mechanism for mechanical bolts and nuts, belonging to the technical field of mechanical connection and locking. Background technique [0002] In mechanical equipment, most of the connections between parts are achieved by moving threads and nuts. However, due to the vibration of the machine during operation, after a period of use, the bolts and nuts will not There is often a loose phenomenon between the nuts. Once this happens, the equipment may not work normally, and even cause other major safety accidents. [0003] In order to overcome the slack phenomenon between bolts and nuts, some bolt and nut locking mechanisms and locking methods have emerged at the historic moment. Although these bolt and nut locking mechanisms have solved the corresponding problems to a certain extent, however, There are also some flaws. Contents of the invention [0004] The object...

[0002] In mechanical equipment, most of the connections between parts are achieved by moving threads and nuts. However, due to the vibration of the machine during operation, after a period of use, the bolts and nuts will not There is often a loose phenomenon between the nuts. Once this happens, it may cause the equipment to fail to work normally, and even cause other major safety accidents.
