Abstract
The utility model discloses a kind of locking washer, comprising: the first pad and the second pad; Described first pad and described second pad include the shim body forming shim through bore; A surface of described shim body has in radioactivity and rotation teeth evenly distributed clockwise; Another surface of the shim body of described first pad and described second pad has the rotating cam that can mutually be engaged.Application technical solutions of the utility model, can improve the external force loads that it bears, and reduce the probability due to the loosened screw that external force loads is excessive or vibrations cause, thus avoid hidden danger and industrial problem.
Description
Technical field
The utility model relates to packing ring, particularly relates to a kind of locking washer.
Background technique
In daily life and industry equipment, equipment Design, manufacture process, usually needing to apply to screw, nut etc., to carry out connection to different workpieces fastening.The utilization of screw, nut, improves the convenience of the scenes such as design, manufacture and routine use.
In the conventional technology, in order to ensure the reliability connected between workpiece, screw and nut when fastening, generally all supporting pad.But the external force loads that the pad in conventional art can bear is smaller, in a lot of application, there will be the comparatively large or vibrations of external force loads and cause loosening of fastening screw, bring hidden danger or a difficult problem to routine use or other commercial Application.
Model utility content
Based on this, be necessary to provide a kind of locking washer, the external force loads that it bears can be improved, reduce the probability due to the loosened screw that external force loads is excessive or vibrations cause, thus avoid hidden danger and industrial problem.
A kind of locking washer, comprising: the first pad and the second pad; Described first pad and described second pad include the shim body forming shim through bore; A surface of described shim body has in radioactivity and rotation teeth evenly distributed clockwise; Another surface of the shim body of described first pad and described second pad has the rotating cam that can mutually be engaged.
In one embodiment, the diameter of described shim through bore and screw diameter adapt.
In one embodiment, the angle of inclination that described rotating cam is engaged mutually is greater than the lift angle angle of screw thread.
Above-mentioned locking washer, comprises the first pad and the second pad.First pad and the second pad have the rotating cam that can mutually be engaged, and in use, the first pad and the second pad can closely be engaged on the workpiece such as screw.Meanwhile, the first pad and the second pad have in radioactivity and rotation teeth evenly distributed clockwise, can improve the external force loads that pad can bear, avoid the hidden danger such as loosened screw.

Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
See Fig. 1 to Fig. 3, provide a kind of locking washer in one embodiment, comprising: the first pad 101 and the second pad 102.First pad 101 and the second pad 102 include the shim body forming shim through bore 103.A surface of the shim body of the first pad 101 and the second pad 102 has in radioactivity and rotation teeth 104 evenly distributed clockwise.Another surface of the shim body of the first pad 101 and the second pad 102 has the rotating cam 105 that can mutually be engaged.
In one embodiment, as shown in Figure 4, locking washer can be applied in the scene of fastened by screw workpiece.Diameter and the screw diameter of shim through bore 103 adapt.Further, as shown in Figure 5, the angle of inclination that rotating cam 105 is engaged mutually is greater than the lift angle angle of screw thread.
The working principle of the locking washer in above-described embodiment is described with Fig. 5:
When putting into locking washer fastening screw, clockwise shearing is stressed, rotate forward after first pad and the second pad are engaged by middle rotating cam, to be arranged clockwise at clamping bolt rotate forward stressedly does not produce external force for the rotation teeth of locking washer upper and lower surfaces.After fastened by screw is static, the tilt angle of engaged rotating cam angle is greater than screw thread lift angle angle, and upper and lower 2 the face teeth of packing ring are firmly coincide with pad teeth due to the pressure of screw and the workpiece threaded portion material stress that is locked change.When screw due to external factor loosen or when relaxing one's efforts, turn clockwise teeth refusal or prevention stressed the produced displacement counterclockwise in upper and lower 2 faces of washer combinations, simultaneously because the tilt angle of the engaged rotating cam of packing ring is greater than the lift angle of screw thread displacement, when thread looseness displacement because the mechanical structure of wedge principle by wedge shape is locked, reach anti-loosening, effect of relaxing one's efforts.
Locking washer in above-described embodiment, comprises the first pad and the second pad.First pad and the second pad have the rotating cam that can mutually be engaged, and in use, the first pad and the second pad can closely be engaged on the workpiece such as screw.Meanwhile, the first pad and the second pad have in radioactivity and rotation teeth evenly distributed clockwise, can improve the external force loads that pad can bear, avoid the hidden danger such as loosened screw.
The above embodiment only have expressed several mode of execution of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
Claims (3)
