Preferably, the left side wall of the nut is provided with a second limiting block.

Preferably, one side of the second gasket is uniformly provided with a U-shaped hole, and the first limiting block penetrates through the inside of one U-shaped hole.

Preferably, the second gasket is arc-shaped.

Preferably, the second stopper is L-shaped.

Preferably, the bottom of one side of the second limiting block is provided with a clamping groove, and the limiting ring is mutually clamped with the clamping groove at the bottom of one side of the second limiting block.

Preferably, the shape of the through hole inside the limiting ring is the same as the shape of the end of the screw.

Compared with the prior art, the utility model has the beneficial effects that:

this novel locking structure that moves of screw through setting up first gasket, first stopper and second gasket, at the in-process that locking screw used, is convenient for fasten the nut to effectual fastening that improves locking screw.

This novel locking structure of moving of screw through setting up spacing ring and second stopper, at the in-process that locking screw used, is convenient for carry on spacingly to the nut, has avoided the nut to lead to the problem of smooth silk because of pressure to the effectual security that improves locking screw.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments; all other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Embodiment one, given by fig. 1, fig. 2, fig. 3 and fig. 4, in order to fasten nut 5, including screw 1, can set up first gasket 2 in the outside of screw 1, set up first stopper 3 at the left side wall of first gasket 2, set up second gasket 4 in the left side of first gasket 2, set up nut 5 in the left side of second gasket 4, and one side of second gasket 4 evenly is provided with U type hole, first stopper 3 runs through in the inside in a U type hole, the shape of second gasket 4 is the arc, when rotating nut 5, make second gasket 4 take place to deform, when second gasket 4 takes place the biggest deformation, nut 5 takes place to fasten, thereby the effectual leakproofness that improves the check screw.

Embodiment two, by figure 1, figure 2, figure 5 and figure 6 give, in order to facilitate carrying on spacingly to nut 5, can set up spacing ring 6 in the left side of nut 5, and the bottom of 7 one sides of second stopper sets up the draw-in groove, the draw-in groove mutual joint of

spacing ring

6 and 7 one sides of second stopper bottom, the shape of the inside through-hole of spacing ring 6 is the same with the shape of 1 tip of screw, when second gasket 4 takes place maximum deformation, cup joint spacing ring 6 in the outside that screw 1 is close to nut 5, make spacing ring 6 and the draw-in groove mutual joint of 7 one sides of second stopper bottom, thereby be convenient for carry on spacingly to nut 5.

The working principle is as follows: when the nut 5 is rotated, the second gasket 4 is deformed, when the second gasket 4 is deformed to the maximum, the nut 5 is fastened, the tightness of the anti-loosening screw is effectively improved, when the second gasket 4 is deformed to the maximum, the limiting ring 6 is sleeved outside the screw 1 close to the nut 5, the limiting ring 6 is clamped with the clamping groove at the bottom of one side of the second limiting block 7, and therefore the nut 5 is limited conveniently.
