A multifunctional anti-loosening nut

Abstract

The invention discloses a multifunctional anti-disengaging nut which comprises a base, a nut body, a spring pad, a spring clamping ring, a circular ring groove and a thread. The thread is arranged in a through hole of the nut body. A punching device exerts pressure on the upper portion of the nut body to make the upper portion of the through hole of the nut body change from the round shape into the oval shape. At least two screw threads can be arranged on the portion, changing into the oval shape, of the upper portion of the through hole of the nut body. The circular ring groove is formed in the bottom of the nut body. The spring pad is arranged in the circular ring groove. The base is inserted into the circular ring groove. The spring pad is arranged above the base. The spring clamping ring is arranged in the circular ring groove. The spring clamping ring stops the base from disengaging from the circular ring groove. The base is formed by a circular ring body and a connecting body arranged on the circular ring body. A through hole of the base is communicated with the through hole of the nut body. Compared with the prior art, the nut can prevent the surface of a fixed object from being damaged, labor is saved in the screwing process, the dual anti-engaging effect is achieved, and the anti-disengaging effect of the anti-engaging nut is good.

Description

【Technical field】 [0001] The invention relates to the technical field of nuts, in particular to the technical field of a multifunctional anti-loosening nut. 【Background technique】 [0002] The nuts commonly used in the market generally include a nut body, a cavity formed in the nut body, and an internal thread formed on the inner wall of the nut body. When in use, it is only necessary to tighten the nut on the bolt. However, in some mechanical structures, vibrations are likely to occur during the use of the device, resulting in loosening of the nut. Once the nut loosens unexpectedly, the connection structure will often be disintegrated, resulting in the malfunction of the equipment and equipment. Although the bolts and nuts can be bonded by dispensing glue after they are locked, they will still fail due to embrittlement after long-term use, resulting in the possibility that the bolts and nuts will still loosen, which will bring inconvenience to production . Although there...

Problems solved by technology

However, in some mechanical structures, vibrations are likely to occur during the use of the device, resulting in loosening of the nut. Once the nut loosens unexpectedly, the connection structure will often be disintegrated, resulting in the failure of the normal operation of the equipment.

Although the bolts and nuts can be bonded by dispensing glue after they are locked, they will still fail due to embrittlement after long-term use, resulting in the possibility that the bolts and nuts will still loosen, which will bring inconvenience to production

Although there are also anti-loosening nuts on the market, at the end of the fastening, the anti-loosening nuts rub against the surface of the fixed object, which is easy to cause damage to the fixed surface, and the tightening is laborious, and the anti-loosening effect is not good. very good
