Problems solved by technology

[0002]Bolts usually cooperate with nuts or threaded holes on the machine to connect and fasten parts. When using bolts to cooperate and lock parts, generally first Put on the spring washer and then lock the parts, rely on the elastic force of the spring washer to increase the friction of the thread on the bolt, and then prevent the bolt from loosening, although this method can play a good role in preventing the bolt from loosening , but before screwing on the bolts, it is necessary to find a suitable spring washer, and then put it on the bolts, and this procedure is more complicated, which brings inconvenience to the operator, and also increases the operation time and reduces the efficiency

Abstract

The invention discloses a bolt with an anti-disengagement device. The bolt comprises a bolt body. The bolt body comprises a bolt head and a bolt rod arranged at one end of the bolt head. The bolt rod comprises a first rod body and a second rod body. The anti-disengagement device is arranged outside the first rod body. Threads are arranged on the outer side of the second rod body. One end of the first rod body is connected with the bolt head. The other end of the first rod body is connected with the second bolt body. The anti-disengagement device comprises a spring gasket and a spacer, wherein the spring gasket is close to the bolt head and connected to the outer side of the first bolt body in a sleeved mode, and the spacer is away from the bolt head and connected to the outer side of the first bolt body in a sleeved mode. The bolt is novel in overall design and simple in design and structure, and has the specific advantages of being simple in structure, reasonable in design, convenient to operate, free of spring gasket finding, good in anti-disengagement effect, high in efficiency, good in locking effect and capable of saving time.

Description

technical field [0001] The invention relates to the technical field of bolts, in particular to a bolt with an anti-loosening device. Background technique [0002] Bolts usually cooperate with nuts or threaded holes on the machine to connect and fasten parts. When using bolts to cooperate and lock parts, it is generally necessary to put on spring washers before locking the parts, relying on the spring washer The elastic force is used to increase the friction of the thread on the bolt, thereby preventing the bolt from loosening. Although this method can effectively prevent the bolt from loosening, it is necessary to find a suitable spring washer before screwing on the bolt. , and then put it on the bolt, and then this procedure is more complicated, which brings inconvenience to the operator, and also improves the operation time and reduces efficiency. [0003] However, in view of the deficiencies in the prior art, it is necessary for the developer to develop a bolt with an an...
