Lock bolt structure

Abstract

The invention provides a lock bolt structure. The lock bolt structure comprises a screw rod, a fastening nut and an an anti-loose clamp spring, wherein the screw rod comprises a rod body with a thread groove; the fastening nut is arranged; the anti-loose clamp spring is arranged; a stop groove is formed in the rod body of the screw rod; the fastening nut is screwed on the rod body; and the anti-loose clamp spring comprises a stop strip, a left clamp ring and a right clamp ring, the left clamp ring and the right clamp ring are arranged at the two ends of the stop strip respectively, and the anti-loose clamp spring is used for abutting against the fastening nut. Under the condition that the anti-loose clamp spring abuts against the fastening nut, the rod body is sleeved with the anti-loose clamp spring, the stop strip is embedded into the stop groove, the left clamp ring or the right clamp ring abuts against the fastening nut, and the left clamp ring or the right clamp ring which does not abut against the fastening nut is embedded into the thread groove in the rod body. According to the lock bolt structure, the fastening nut can be prevented from moving in the axial direction along the rod body of the screw rod, loosening of a bolt in the connecting process is prevented, it is ensured that parts are firmly connected, and the problem that in the prior art, in the machining or mechanical equipment part assembling process, due to bolt connection looseness, part connection is not firm is solved.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing and assembly, in particular to an anti-loosening bolt structure for fastening components. Background technique [0002] In the process of mechanical processing and assembly of mechanical equipment parts, bolts are often used for mechanical connection, but ordinary bolts may loosen in working environments such as mechanical vibration, high temperature or material fatigue, resulting in the failure of the bolt's fastening function, which greatly affects mechanical production. The safety and accuracy of the equipment, especially some key parts of the equipment must not allow the problem of loose connection of parts. Usually, spring washers are often used in conjunction with the bolt fastening process, but the spring washers have poor anti-loosening ability. In some equipment It is difficult to achieve a good anti-loosening effect in the key parts of the body, therefore, a device or st...
