Abstract
The utility model discloses a locking nut which comprises a nut body, wherein a plurality of anti-loosening-retreating bulges are arranged on the end surface which is used for being bonded with the connected component, of the nut body, and the anti-loosening-retreating bulges can be cone-shaped, circular-table-shaped, pyramid-shaped or prismatic-table-shaped. The locking nut disclosed by the utility model has the advantages that because the plurality of anti-loosening-retreating bulges are arranged on the end surface which is used for being bonded with the connected component, of the nut body, after the locking nut disclosed by the utility model is screwed, namely, when the locking nut is tightly bonded with the surface of the connected component, the friction force between the locking nut disclosed by the utility model and the surface of the connected component is increased, thus the purpose of preventing the automatic loosening and retreating of the locking nut disclosed by the utility model along a thread on a bolt or a screw rod is achieved.
Description
Technical field:
The utility model relates to a kind of fastening piece, specifically is a kind of locking nut.
Background technique:
The nut effect is to be fastenedly connected two parts that have through hole, it usually and bolt or screw rod be used.Because the end face of plain nut is generally smooth plane; Therefore; When this nut cooperates with bolt or screw rod when being fastened on two parts that have a through hole; This nut and can be very little by the frictional force between union piece, particularly when receiving external force vibration, nut will be easy to along the screw thread on bolt or the screw rod voluntarily pine move back.
The model utility content:
The technical problem that the utility model will solve is, provides a kind of when receiving external force vibration, can effectively prevent along the locking nut that moves back of pine voluntarily of the screw thread on bolt or the screw rod.
The technical solution of the utility model is that a kind of locking nut with following structure is provided: comprise nut body, wherein, nut body is used for being provided with a plurality of locking convexities of moving back with the end face that is fitted by union piece.
The described locking nut of the utility model, wherein, the locking convexity of moving back can be taper shape or frustoconic shape or pyramid shape or terrace with edge shape.
After adopting above structure; Compared with prior art; The utility model locking nut has the following advantages: because nut body is used for being provided with a plurality of locking convexities of moving back with the end face that is fitted by union piece; Therefore, behind the utility model locking nut screwing, promptly locking nut is when being close to by the surface of union piece; The utility model locking nut and will be increased by the frictional force between the union piece surface prevents that the utility model locking nut is along the pine purpose of moving back voluntarily of the screw thread on bolt or the screw rod thereby reach.
Description of drawings:
Fig. 1 is the stereochemical structure profile schematic representation of the utility model locking nut;
Embodiment:
Below in conjunction with accompanying drawing and embodiment the utility model locking nut is done further explain:
As shown in Figure 1; In this embodiment; The utility model locking nut comprises that nut body 1 lockingly moves back protrudingly 3 with a plurality of, a plurality ofly lockingly moves back protruding 3 and is distributed in nut body 1 and is used for and the end face 2 that is fitted by union piece, and locking protruding 3 the shape of moving back is frustoconic shape.
Above-described embodiment describes the preferred implementation of the utility model; Be not that scope to the utility model limits; 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 technological scheme of the utility model all should fall in the definite protection domain of the utility model claims.
