Lock nut capable of being quickly dismounted and mounted

Abstract

The invention discloses a lock nut capable of being quickly dismounted and mounted. The lock nut comprises a nut body and a U-shaped spring piece. Nut knurling strips are arranged on the outer side of the nut body, a threaded through hole is formed in the middle of the nut body, and a nut protective sleeve is arranged outside the nut body. Longitudinal protective knurling strips are arranged on the inner side of the nut protective sleeve and matched with the nut knurling strips. The upper surface of the U-shaped spring piece is connected with the nut body, a through hole through which the nut body penetrates is formed in the middle of the U-shaped spring piece, and the through hole and the threaded through hole are coaxially formed. The lock nut has the characteristics of being high in clamping force, good in clamping effect and not liable to disengage.

Description

technical field [0001] The invention relates to the technical field of mechanical fasteners, in particular to a quick dismountable lock nut. Background technique [0002] In the field of fasteners, the bolts are first passed through the through holes of the connected parts, and then the nuts are installed on the ends of the bolts. In places where the installation space is narrow, ordinary nuts are not easy to fix, which causes some unnecessary troubles in use. Trouble, and when tightening nuts and bolts, because the contact area of ​​the nuts is small and the torque of the bolts is large, it is easy to cause damage to the connected parts during use, and the nuts are also easy to fall off during use. [0003] In recent years, people have been improving nuts, and reed nuts have appeared. Reed nuts are one of the more commonly used fasteners in the market, especially in the field of automotive interior installation, and the reed nuts used in the market , the upper and lower re...

[0002] In the field of fasteners, the bolts are first passed through the through holes of the connected parts, and then the nuts are installed on the ends of the bolts. In places where the installation space is narrow, ordinary nuts are not easy to fix, which causes some unnecessary troubles in use. It is troublesome, and when tightening the nuts and bolts, due to the small contact area of ​​the nuts and the large torque of the bolts, it is easy to cause damage to the connected parts during use, and the nuts are also easy to fall off during use

[0003] In recent years, people have been improving nuts, and reed nuts have appeared. Reed nuts are one of the more commonly used fasteners in the market, especially in the field of automotive interior installation, and the reed nuts used in the market , the upper and lower reeds are easy to loosen, and the clamping force is not strong, resulting in a greatly reduced fastening effect
