Abstract

The utility model relates to a locking combination of nut washer, including nut and gasket, the lower extreme of nut is equipped with the nut fluted disc, the upper end of gasket is equipped with the gasket fluted disc that forms the hook of turning over with the nut fluted disc, nut fluted disc and gasket fluted disc counter catch hold of with a hook direction and nut to screw the direction unanimous, nut fluted disc and gasket fluted disc comprise anti - gullet tooth of nut and the anti - gullet tooth circumference evenly distributed of gasket respectively, the anti - gullet tooth of nut includes first inclined plane and the first hook face of turning over, the anti - gullet tooth of gasket includes the anti - hook face of second inclined plane and second, first inclined plane is 5~10 degrees bigger with the contained angle of horizontal plane than second inclined plane with the contained angle of horizontal plane, the shake power that produces when going or move when the car has back lead angle owing to the gasket, so nut and screw rod are in the state of screwing up all the time, it is not enough rotatory in driving the gasket, effectual slow down not hard up.

Description

The anti-pine combination of nut shim

Technical field

This utility model is related to a kind of nut, particularly to the anti-pine combination of nut shim.

Background technology

The nut of boss bolt due to screw thread characteristic so that nut after tightening it is easy to along helical direction rotation Turn face and lead to nut loosening, in particular by the impact of external force, this situation is even more susceptible to, thus serious impact bolt Firm effect, be susceptible to security incident.

Utility model content

In place of solving the deficiencies in the prior art, this utility model provides the anti-pine combination of nut shim.

The anti-pine combination of nut shim, including nut and pad, the lower end of this nut is provided with nut fluted disc, the upper end of this pad It is provided with the pad fluted disc forming anti-hook with nut teeth disk, the anti-hook direction of this nut fluted disc and pad fluted disc and the side of screwing of nut To consistent.

Further, this nut fluted disc and pad fluted disc are distributed by the anti-briar tooth of nut and pad anti-briar tooth even circumferential respectively Composition, the anti-briar tooth of this nut includes the first inclined-plane and the first anti-hook side, and the anti-briar tooth of this pad includes the second inclined-plane and the second anti-hook Face.

Further, bigger than the angle on the second inclined-plane and horizontal plane with the angle of horizontal plane 5 ~ 10 degree of this first inclined-plane.

The beneficial effects of the utility model:

Due to nut fluted disc and pad fluted disc anti-hook direction and nut to screw direction consistent, so tightening nut When, nut band mobile gasket is tightened, and screwing force is common, because the angle of this first inclined-plane and horizontal plane is than the second inclined-plane and horizontal plane Big 5 ~ 10 degree of angle, so the first inclined-plane and the second inclined-plane are linear contact lay, the anti-briar tooth of such nut nut when loosening pad On the anti-briar tooth of piece, there is rear lift angle, when the float force producing when car is in traveling or motion, or, the first inclined-plane during nut loosening Top line can be stuck in and make screw rod and nut be in tight condition on the second inclined-plane of the anti-briar tooth of pad, be not enough to carry mobile gasket rotation Turn, effectively slow down loosening, need the use power more much bigger than screwing force of inertia just can disassemble when when to be loosened.

Brief description

Fig. 1 is structural representation of the present utility model.

Fig. 2 separates schematic diagram for the anti-briar tooth of nut briar tooth anti-with pad.

Fig. 3 is the anti-briar tooth of nut and pad anti-briar tooth combination diagram.

Specific embodiment

As Fig. 1 to Fig. 2, the anti-pine combination of nut shim, including nut 1 and pad 2, the lower end of this nut 1 is provided with nut teeth Disk 11, the upper end of this pad 2 is provided with the pad fluted disc 21 forming anti-hook with nut fluted disc 11, this nut fluted disc 11 and pad fluted disc 21 anti-hook direction and nut to screw direction consistent.

This nut fluted disc 11 and pad fluted disc 21 are divided by the anti-briar tooth of nut 111 and the anti-briar tooth of pad 211 even circumferential respectively Cloth forms, and the anti-briar tooth of this nut includes the first inclined-plane 1111 and the first anti-hook side 1112, and the anti-briar tooth of this pad includes the second inclined-plane 2111 and the second anti-hook side 2112.

The angle of this first inclined-plane 1111 and horizontal plane is than big 5 ~ 10 degree of the angle on the second inclined-plane 2111 and horizontal plane.

Last it is noted that above example is only in order to illustrate the technical solution of the utility model and unrestricted, although With reference to preferred embodiment, this utility model is described in detail, it will be understood by those within the art that, can be right The technical solution of the utility model is modified or equivalent, the spirit without deviating from technical solutions of the utility model and model Enclose, it all should be covered in the middle of right of the present utility model.

Claims

1. the anti-pine combination of nut shim, including nut and pad it is characterised in that the lower end of this nut is provided with nut fluted disc, should The upper end of pad is provided with the pad fluted disc forming anti-hook with nut teeth disk, the anti-hook direction of this nut fluted disc and pad fluted disc and spiral shell It is female that to screw direction consistent.

2. the anti-pine combination of nut shim according to claim 1 is it is characterised in that this nut fluted disc and pad fluted disc are distinguished It is made up of the anti-briar tooth of nut and the distribution of pad anti-briar tooth even circumferential, the anti-briar tooth of this nut includes the first inclined-plane and the first anti-hook Face, the anti-briar tooth of this pad includes the second inclined-plane and the second anti-hook side.

3. the anti-pine combination of nut shim according to claim 2 is it is characterised in that the angle of this first inclined-plane and horizontal plane Bigger than the angle on the second inclined-plane and horizontal plane 5 ~ 10 degree.
