Abstract
The invention discloses a locknut. The locknut comprises a nut body. A threaded through hole is formed in the nut body. A boss coaxial with the threaded through hole is arranged on the upper end face of the nut body. The boss is in a ring shape and is folded from inside to outside to form a protruding part and a folded groove. The protruding part is arranged on the side, close to the axis of the nut body, of the middle of the boss, and the folded groove is formed in the outer side of the boss. The locknut is simple in structure and good in locking effect.
Description
Technical field
The present invention relates to field of mechanical technique, particularly relate to a kind of lock nut.
Background technique
Nut usually and bolt, screw fit uses and plays the effect connecting fastening component, when using screw bolt and nut to lock component, in order to prevent loosening of nut, general elder generation to overlap on bolt after spring washer again nut on bolt, rely on the frictional force that the elastic force of spring washer increases nut and is locked between component, and then prevent loosening of nut, although this method can well play the effect of nut anti-looseness, but also there is a deficiency, that is exactly before screwing on nut, first to overlap spring washer on bolt, use just cumbersome like this.
Summary of the invention
For the deficiency that prior art exists, object of the present invention just there are provided a kind of lock nut, and structure is simple, and locking effect is good.
To achieve these goals, the technical solution used in the present invention is such: a kind of lock nut, comprises nut body, is provided with tapped through hole in nut body, and the upper-end surface of described nut body is provided with the boss coaxial with tapped through hole; In the form of a ring, boss is folded to form protuberance and folding groove by Inside To Outside to described boss; Described protuberance is arranged at the axis side near nut body in the middle part of boss, and described folding groove is arranged at outside boss.
As a kind of preferred version, the end face of described boss is evenly equipped with male member.
As a kind of preferred version, described nut body offers restraining groove group, described restraining groove group comprises two grooves, and two grooves are symmetricly set in the bottom of nut body.
As a kind of preferred version, described restraining groove group is two groups or more.
As a kind of preferred version, the cross section of described nut body is regular hexagon, and the neutral position on each bar limit of nut body all has a groove, forms three groups of restraining groove groups.
As a kind of preferred version, the cross section of described nut body is circular, and the bottom of nut body evenly offers six grooves, forms three groups of restraining groove groups.
Compared with prior art, beneficial effect of the present invention:
1. owing to being provided with boss, and be evenly equipped with male member at raised head face, add the frictional force between nut and the component be locked, there is the function preventing from preferably loosening;
2. structure is simple, and locking effect is good, often reusable, and the life-span is long.
