Abstract
A bolt belongs to a threaded connection piece, and comprises a bolt head and a threaded rod which are connected into a whole, wherein one side of the end face on the bolt head, which is connected with the threaded rod, is provided with an arc disc; and a circular arc groove is arranged at the part on the arc disc, which is connected with the threaded rod. The bolt has the advantages that the bolt which does not need to be sheathed with a spring washer has the anti-loosening function.
Description
Technical field:
The utility model relates to a kind of threaded connector, specifically is a kind of bolt.
Background technique:
Bolt usually with nut or machine on the tapped hole cooperation play the effect that is connected fastening component, tapped hole on using bolt and machine cooperates when locking component, lock component again after generally will putting spring washer earlier, the elastic force of dependence spring washer increases the frictional force of the screw thread on the bolt, and then prevent the loosening of bolt, though this method can well play the effect of screw retention, but also there is a deficiency, that is exactly before screwing on bolt, to on bolt, put spring washer earlier, use just cumbersome like this.
The model utility content:
The technical problems to be solved in the utility model is, providing a kind of does not need to put spring washer and can prevent the bolt that becomes flexible.
Technical solution of the present utility model is, provide a kind of bolt: comprise bolt head and threaded stem with following structure, bolt head and threaded stem connect into an integral body, wherein, end face one side that is connected with threaded stem on the bolt head has an arc disk, and is provided with a circular groove with the threaded stem joint on the arc disk.
After adopting above structure, compared with prior art, the utility model bolt has the following advantages: to rely on spring washer to carry out in use locking different with common bolt, because end face one side that is connected with threaded stem on the bolt head of the utility model bolt has an arc disk, and be provided with a circular groove with the threaded stem joint on the arc disk, after screwing bolt, resiliently deformable can take place in the arc disk on the bolt head, produce the elastic deformation force, rely on the elastic deformation force of arc disk to replace the elastic force of spring washer to prevent the loosening of bolt, therefore, the utility model bolt does not need to put spring washer again and prevents the loosening of bolt.
Description of drawings:
Fig. 1 is that the master of the utility model bolt looks the sectional structure schematic representation.
Fig. 2 is the perspective view of the utility model bolt.
Embodiment:
Below in conjunction with the drawings and specific embodiments the utility model bolt is described further:
As depicted in figs. 1 and 2, in this embodiment, the utility model bolt comprises bolt head 1 and threaded stem 2, bolt head 1 and threaded stem 2 connect into an integral body, end face one side that is connected with threaded stem 2 on the bolt head 1 has an arc disk 3, and be provided with a circular groove 4 with threaded stem 2 joints on the arc disk 3, the lower end surface of arc disk 3 is the plane perpendicular to threaded stem.
Above-described embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection domain of the utility model claims.
