Description
Technical field
It the utility model is related to machanical fastener technical field, and in particular to a kind of packing ring.
Background technology
At present, in the market major part stop nut all realizes locking purpose with the method for increase friction, actually should
Lubricant grease will be applied with middle most of bolt, larger clamping force is obtained for antirust and with less pretightning force, and protect
It screw thread, can so reduce frictional force, locking effect is had a greatly reduced quality.The present invention provides a kind of packing ring and overcomes this defect, uses
This packing ring and bolt or after being meshed by fastener, then engaged with ratchet structure and corresponding nut, make nut can only
Rotate in one direction to realize locking purpose.
Utility model content
For problems of the prior art, the purpose of this utility model is to provide a kind of packing ring, and it is effectively solved
Problems of the prior art.
To achieve the above object, the utility model uses following technical scheme：
A kind of packing ring, the packing ring include ring body, are provided with the lower surface of the ring body for preventing ring body
The bottom anti-rotation structure of own rotation；The upper strata anti-rotation for preventing nut or bolt from rotating is provided with the upper surface of ring body
Structure；The bottom anti-rotation structure is the multiple projections being arranged on the lower surface of ring body；The upper strata anti-rotation structure is to set
Multiple elastic pawls on the upper surface of ring body are put, the front lower portion of the elastic pawl is provided with strip limited block.
Further, the elastic pawl is arranged radially using the center of the ring body as the center of circle, and its front end is to updip
Tiltedly tilt or to upper overturning.
Further, the bottom anti-rotation structure is 3 projections being arranged on the lower surface of the ring body, 3 projections
It is circumferentially evenly distributed along the lower surface of ring body.
The utility model has following advantageous effects：
The utility model is the structure for preventing from for upper and lower two layers rotating, simple in construction, easy to use, can be according to reality
Situation selects anti-rotation structure, and very flexibly, the application of limited block causes ratchet not to be pressed down easily, ensure that service life.
The utility model is reasonable in design, can reach the purpose of retaining.
Brief description of the drawings
Fig. 1 is the stereogram of the utility model embodiment；
Fig. 2 is the front view of the utility model embodiment；
Fig. 3 is the upward view of the utility model embodiment.
Embodiment
Below, refer to the attached drawing, the utility model is more fully illustrated, shown shown in the drawings of of the present utility model
Example property embodiment.However, the utility model can be presented as a variety of multi-forms, it is not construed as being confined to what is described here
Exemplary embodiment.And these embodiments are to provide, so that the utility model is fully and completely, and will be of the present utility model
Scope is fully communicated to one of ordinary skill in the art.
As Figure 1-3, the utility model provides a kind of packing ring, and the packing ring includes ring body 1, the lower end of ring body 1
The bottom anti-rotation structure for preventing ring body own rotation is provided with face；It is provided with the upper surface of ring body 1 for preventing
The upper strata anti-rotation structure that only nut or bolt rotate；Bottom anti-rotation structure is the multiple projections being arranged on the lower surface of ring body
4；Upper strata anti-rotation structure is the multiple elastic pawls 2 being arranged on the upper surface of ring body, and the front lower portion of elastic pawl 2 is set
There is strip limited block 3.The application of limited block 3 causes ratchet not to be pressed down easily, ensure that service life.
Elastic pawl 2 is arranged radially using the center of ring body 1 as the center of circle, its front end be inclined upwardly tilting or upwards
Flange.
Bottom anti-rotation structure is 3 projections being arranged on the lower surface of the ring body, and 3 projections are along under ring body
End face is circumferentially evenly distributed.
After the utility model is meshed with packing ring and bolt or by fastener, then with ratchet structure and corresponding spiral shell
Mother's engagement, makes nut to rotate in one direction to realize locking purpose.
It is described above simply to illustrate that the utility model, it is understood that the utility model be not limited to the above implementation
Example, meets the various variants of the utility model thought within the scope of protection of the utility model.
