Abstract

The utility model relates to a check nut and belongs to a fastener. The check nut is generally used in combination with a bolt or a threaded rod and is used for firmly connecting two parts with through holes. The check nut comprises a nut body, wherein an axial threaded through hole is formed on the nut body; two radial threaded through holes for forcing screws to screw in are formed on the side wall of the nut body; and the two radial threaded through holes are symmetrical and coaxial. The check nut does not automatically loosen along the screw thread on the bolt or the threaded rod easily under vibration.

Description

Lock nut
Technical field:
The utility model relates to a kind of fastening piece, specifically is a kind of lock nut.
Background technique:
Nut is one of fastening piece commonly used in the mechanical field, and it is used with bolt or screw rod usually, for being fastenedly connected two with the part of through hole.Because the end face of plain nut mostly is smooth plane, therefore, when this nut cooperate with bolt or screw rod be fastened on two with the part of through hole on after, it and the frictional force that is connected between part can be very little, especially when being subject to vibrating, this nut be easy to along the screw thread on bolt or the screw rod voluntarily pine move back.
The model utility content:
The technical problems to be solved in the utility model is, provides a kind of when being subject to vibrating, and is difficult for along the lock nut that moves back of pine voluntarily of the screw thread on bolt or the screw rod.
Technical solution of the present utility model is, provide a kind of lock nut with following structure: comprise nut body, have the axial screw thread through hole on the nut body, wherein, have two on the sidewall of nut body and supply to compress the radially tapped through hole that screw is screwed into, two symmetrical and coaxial lines of described radially tapped through hole.
After adopting above structure, compared with prior art, the utility model lock nut has the following advantages: with the prior art nut when being subject to vibrating, be easy to along the screw thread on bolt or the screw rod voluntarily pine move back difference, the utility model lock nut has two radially tapped through holes that supply the compression screw to be screwed at the sidewall of nut body, therefore, after the utility model lock nut tightens on bolt or the screw rod, people can use two pieces of housing screws to be screwed into respectively two radially in the tapped through hole, and the head that finally makes housing screw is pressed on bolt or the screw rod, like this, the utility model lock nut when being subject to vibrating, be difficult to along the screw thread on bolt or the screw rod voluntarily pine move back.
Description of drawings:
Fig. 1 is the stereochemical structure profile schematic representation of the utility model lock nut.
Embodiment:
Below in conjunction with the drawings and specific embodiments the utility model lock nut is described in further detail:
As shown in Figure 1, in this embodiment, the utility model lock nut comprises nut body 1, have axial screw thread through hole 3 on the nut body 1, have two on the sidewall of nut body 1 and supply to compress 2, two described radially tapped through hole 2 symmetrical and coaxial lines of radially tapped through hole that screw is screwed into.
The using method of the utility model lock nut is: after the utility model lock nut tightens on bolt or the screw rod, people can use two pieces of housing screw (not shown)s to be screwed into respectively two radially in the tapped through hole 2, and the head that finally makes housing screw is pressed on bolt or the screw rod, like this, the utility model lock nut when being subject to vibrating, be difficult to along the screw thread on bolt or the screw rod voluntarily pine move back.
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.
