Abstract

The utility model discloses a locknut, including the nut body, this internal screw through -hole that is provided with of nut, the up end of nut body is provided with the boss coaxial with the screw thread through -hole, the boss is the ring -type, and the boss is by the inboard to folding protruding portion and the folding recess of forming in the outside, the protruding portion sets up the axis one side that is close to the nut body in the middle part of the boss, folding recess sets up in the boss outside. The utility model discloses a locknut simple structure locks effectually.

Description

A kind of lock nut
Technical field
The utility model relates to field of mechanical technique, has particularly related 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.
Invention model utility content
For the deficiency that prior art exists, the purpose of this utility model 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 adopted in the utility model 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, the beneficial effects of the utility model:
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.

Embodiment
Below in conjunction with specific embodiment, the utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
Embodiment one:
As shown in Figure 1, a kind of lock nut, comprises nut body 1, is provided with tapped through hole 2 in nut body 1, and the upper-end surface of described nut body 1 is provided with the boss 3 coaxial with tapped through hole 2; In the form of a ring, boss 3 is folded to form protuberance 31 and folding groove 32 by Inside To Outside to described boss 3; Described protuberance 31 is arranged at the axis side near nut body 1 in the middle part of boss 3, and described folding groove 32 is arranged at outside boss 3; As shown in Figure 2, the end face of the preferred described boss 3 of the utility model is evenly equipped with male member 33.During concrete enforcement as shown in Figure 3, instrument is utilized to be tightened on screw rod 4 by nut body 1, nut body 1 is provided with boss 3 side and component 5 surface contact, resiliently deformable is there is in boss 3 under the extruding of axial force, protuberance 31 tightens up to nut body 1 center until protuberance 31 is absorbed in screw flight 41, nut body 1 is subject to protuberance 31 opposition vertically, nut thread 21 in tapped through hole 2 and screw flight 41 close contact realize the self-locking of nut, wherein on the end face of boss 3, be evenly equipped with male member 33, the frictional force in order to increase between boss 3 and component 5.
Embodiment two:
As shown in Figure 4, described nut body 1 offers restraining groove group, described restraining groove group comprises two grooves 11, and two grooves 11 are symmetricly set in the bottom of nut body 1; Described restraining groove group is two groups or more; The cross section of described nut body 1 is regular hexagon, and the neutral position on each bar limit of nut body 1 all has a groove 11, forms three groups of restraining groove groups.
During concrete enforcement as shown in Figure 5, the utility model and swivel pin 6, locating stud 7 with the use of, this swivel pin 6 offers positioning hole, one end that during assembling, swivel pin 6 has a positioning hole is passed by tapped through hole 2, when positioning hole and any one group of groove 11 are to time into a line, by locating stud 7 through restraining groove group, assembling can be completed.
Embodiment three:
As shown in Figure 6, described nut body 1 offers restraining groove group, described restraining groove group comprises two grooves 12, and two grooves 12 are symmetricly set in the bottom of nut body 1; Described restraining groove group is two groups or more; The cross section of described nut body 1 is circular, and the bottom of nut body 1 evenly offers six grooves 12, forms three groups of restraining groove groups.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and distortion, these improve and distortion also should be considered as protection domain of the present utility model.
