Abstract
The utility model discloses an anti-loosening bolt consisting of a bolt head (1) and a bolt rod (3), wherein the bolt head (1) is integrated with the bolt rod (3); and the bolt rod (3) is provided with screw thread. The anti-loosening bolt is characterized in that the end surface of the bolt rod (3) which is not connected with the bolt head (1) is an arc surface (5). The anti-loosening bolt has the advantages that the anti-loosening bolt can be effectively prevented from vibrating with the spare parts, and the manufacturing material of the bolt can be greatly saved.
Description
Technical field:
The utility model relates to a kind of chek bolt.
Background technique:
The phenomenon of vibration takes place in interconnective two component in the course of the work through regular meeting; also follow one for the chek bolt that prevents to connect on the above-mentioned parts and play vibration; people can be provided with one section cylindrical body or polygon cylinder in the screw rod bottom of chek bolt usually; can effectively prevent not only that by mode on third party's part that cylindrical body or polygon cylinder are inserted into chek bolt from following component and vibrating together, and the stationarity when having guaranteed component work greatly.But,, thereby cause certain waste of material because the length of above-mentioned cylindrical body or polygon cylinder is generally all long.
The model utility content:
The technical problems to be solved in the utility model is that a kind of chek bolt that can save material greatly is provided.
Technical solution of the present utility model is, a kind of chek bolt with following structure is provided, and it is made up of bolt head and screw rod two-part; Described bolt head and screw rod connect into an integral body; Described screw rod is provided with screw thread; The end face that described screw rod is not connected with bolt head is an arc surface.
After adopting above structure, compared with prior art, the utlity model has following advantage: establish one section cylindrical body or polygon cylinder in the screw rod bottom different with prior art, because the utility model has been arranged to arc surface with the end face that screw rod is not connected with bolt head, the user can utilize arc surface to be inserted in the groove of being located on third party's part, therefore, the utility model has been saved the material of bolt greatly relying on arc surface to prevent that chek bolt from following when component vibrate together.
As a kind of improvement of the present utility model, described bolt head can be provided with boss near on the end face of screw rod.Because bolt head is provided with boss near the end face of screw rod, therefore, the utility model can be inserted into boss and is connected in the through hole that part is provided with after assembling, thus can improve greatly with component between the soundness that is connected.
