Abstract
The invention discloses an anti-loosening nut. The anti-loosening nut comprises a nut body. A disc is arranged on one end face of the nut body. A threaded through hole is formed in the nut body. An annular groove is formed in the position, close to the disc, of the circumferential wall of the threaded through hole. Inner grooves are formed in the inner side wall of the nut body. Outer grooves are formed in the outer side wall of the nut body. The inner grooves and the outer grooves are formed in the nut body in an equal-angle mode and located below the annular groove. Radial screw holes are formed in the positions, between the inner grooves and the outer grooves, of the nut body. Screws are arranged in the radial screw holes and connected with the nut body. The anti-loosening nut 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 nut preventing loosening.
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 nut preventing loosening, 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 nut preventing loosening, comprise nut body, one end face of described nut body is provided with disk, be provided with tapped through hole in nut body, the perisporium of described tapped through hole is provided with annular groove near disk place; The madial wall of described nut body has on inner groovy, outer side wall and have outer groove, described inner groovy and outer groove equal angles to be arranged on nut body and to be positioned at the below of annular groove, and nut body between inner groovy and outer groove is provided with radial screw; Be provided with screw in described radial screw, this screw is connected with nut body.
As a kind of preferred version, the edge of described disk is evenly equipped with at least two lugs.
As a kind of preferred version, the cross section of described nut body is regular hexagon.
As a kind of preferred version, described inner groovy is provided with six, and is uniformly distributed along nut body madial wall circumferencial direction.
As a kind of preferred version, described outer groove is provided with six, and is arranged on each bar limit of nut body outer side wall.
As a kind of preferred version, one end that described screw is positioned at tapped through hole is provided with sprue.
Compared with prior art, beneficial effect of the present invention:
1. owing to being provided with disk, and be evenly equipped with lug at disk border, 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.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is stereogram of the present invention.
Embodiment
Below in conjunction with specific embodiment, the invention will be further described.Following examples only for technological scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
Embodiment:
As shown in Figure 1, a kind of nut preventing loosening, comprises nut body 1, an end face of described nut body 1 is provided with disk 2, is provided with tapped through hole 3 in nut body 1, and the perisporium of described tapped through hole 3 is provided with annular groove 4 near disk 2 place; The madial wall of described nut body 1 has on inner groovy 5, outer side wall and have outer groove 6, described inner groovy 5 and outer groove 6 equal angles to be arranged on nut body 1 and to be positioned at the below of annular groove 4, and nut body 1 between inner groovy 5 and outer groove 6 is provided with radial screw 7; Be provided with screw 8 in described radial screw 7, this screw 8 is connected with nut body 1; The cross section of described nut body 1 is regular hexagon; Described inner groovy 5 is provided with six, and is uniformly distributed along nut body 1 madial wall circumferencial direction; Described outer groove 6 is provided with six, and is arranged on each bar limit of nut body 1 outer side wall; One end that described screw 8 is positioned at tapped through hole 3 is provided with sprue 9.One end face of nut body 1 of the present invention is provided with disk 2, the perisporium of tapped through hole 3 is provided with annular groove 4 near disk 2 place, when locking component, one end nut with disk 2 first screws in bolt, the nut body 1 between disk 2 and annular groove 4 can be made after disk 2 is stressed to deform, thus make nut thread herein be pressed on the thread of bolt, prevent loosening of nut; Meanwhile, tightening screw 8 is until screw 8 to be screwed into completely in outer groove 6 and after sprue 9 and the screw thread thread of bolt compress, effectively can to prevent the loosening of nut after tightening screw 8 further.
As shown in Figure 2, the edge of the preferred described disk 2 of the present invention is evenly equipped with 12 lugs 10, and when after tightening nut, lug 10 is pressed on the component that are locked firmly, better can prevent loosening of nut.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and distortion, these improve and distortion also should be considered as protection scope of the present invention.
