Problems solved by technology

Another traditional method uses cotter pins to prevent loosening. The disadvantages are low efficiency and high labor intensity. Iron filings and burrs generated during drilling are difficult to remove, which affects the cleanliness of the hydraulic cylinder and affects product quality. Therefore, we propose a Nut anti-loosening structure

Embodiment Construction

[0027] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0028] refer to Figure 1-3 As shown, a nut anti-loosening structure includes a anti-loosening nut 1 and a bolt rod 2. The anti-loosening nut 1 and the bolt rod 2 are flexibly connected by internal and external threads, and a tapered ring is fixedly installed on the outer surface of the top end of the anti-loosening nut 1. 3. The outer surface of the top end of the anti-loosening nut 1 and the conical ring 3 are provided with a bolt groove 4, the outer surface of the top end of the bolt rod 2 is fixedly installed with a screw 5, and the outer surface of the screw 5 is provided with an annular groove 6 near the top. A stopper 7 is fixedly installed on the outer surface of the top end of the screw 5 close to the annular groove 6 .

Abstract

The invention discloses a nut anti-loosening structure. The nut anti-loosening structure comprises an anti-loosening nut and a bolt rod, the anti-loosening nut and the bolt rod are movably connected through internal and external threads, a conical ring is fixedly installed on the outer surface of the top end of the anti-loosening nut, and bolt grooves are formed in the outer surfaces of the top ends of the anti-loosening nut and the conical ring in a penetrating manner. A screw rod is fixedly installed on the outer surface of the top end of the bolt rod, an annular groove is formed in the position, close to the top end, of the outer surface of the screw rod, and a stop block is fixedly installed at the position, close to the annular groove, of the outer surface of the top end of the screwrod. According to the nut anti-loosening structure, one end of the nut is conical, an annular groove is formed in one end of a bolt, the conical portion of the nut is squeezed into the annular grooveof the bolt through an anti-loosening bolt machining device, when the bolt vibrates, the nut is always in a retaining state, the anti-loosening effect is well achieved, and the anti-loosening bolt machining device is simple in machining process, convenient to operate and convenient to manage.

Description

technical field [0001] The invention relates to the field of anti-loosening structures, in particular to a nut anti-loosening structure. Background technique [0002] When the hydraulic cylinder is working, due to the need to move back and forth, it is easy to generate vibration, impact and high temperature, so a bolt structure that can prevent loosening is required to fix the piston; [0003] The existing nut anti-loosening structure has certain disadvantages in use. The hydraulic cylinder piston is generally fixed by nuts. The traditional nut anti-loosening methods include spring washers, lock nuts, glue, etc., but the hydraulic cylinder has vibration during work. , impact, high temperature and other working conditions exist, the nuts will loosen over time. Another traditional method uses cotter pins to prevent loosening. The disadvantages are low efficiency and high labor intensity. Iron filings and burrs generated during drilling are difficult to remove, which affects t...
