Abstract

The utility model discloses dynamic device components and parts packing ring, packing ring comprises fastening foot, inner ring pad and some locking pin, and fastening foot is the semi-cylindrical hill be connected with inner ring pad inner ring, and locking pin is all connected with inner ring pad outer ring, and the quantity of locking pin is 4 ~ 6.The utility model is when screw is subject to extraneous vibration and oppositely exits, and the reverse lines by some locking pin is stuck by it, and the retaining effect being arranged to lock pin of fastening foot reaches best; Locking pin after cutting and pull-up step with inner ring pad not in one plane, when nut tightens, locking pin, by giving nut the great elastic force contrary with tightening direction, makes nut very fastening.

Description

Dynamic device components and parts packing ring
Technical field
The utility model relates to technical field of electric equipment, more particularly, particularly relates to the packing ring that a kind of fixing dynamic device components and parts use.
Background technique
When the components and parts such as the relay be widely used in electric industry, fus are arranged on equipment, usually make to be screwed, need to arrange packing ring between screw and components and parts mounting hole site.
Plain cushion of the prior art or bullet pad all only play fastening effect, and without stopping function, when components and parts are in dynamic environment, such as rail traffic vehicles, owing to jolting for a long time, components and parts very easily loosen and come off.Internal tooth chrysanthemum packing ring or external tooth chrysanthemum packing ring, the hardness of tooth is comparatively large, the screw thread be in contact with it easy to wear, and all without obvious elasticity, cannot give the external force that nut is larger, and nut is fastening not.
Model utility content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provides one can give the enough elastic force of nut and make it enough fastening, can play again the dynamic device components and parts packing ring of fabulous retaining effect.
The technical solution of the utility model is achieved in that dynamic device components and parts packing ring, comprise washer body, described washer body comprises fastening foot, inner ring pad and some locking pin, described fastening foot is the semi-cylindrical hill be connected with inner ring pad inner ring, its shape of cross section and washer body the keyway overlapped on screw match; Described some locking pin are all connected with inner ring pad outer ring, lock the outer ring of pin by the outer shroud pad be connected with inner ring pad outer ring after some deciles, the direct cutting through the center of circle is done at equal diversion point, this depth of cut is equal with inner ring gasket ring width, again by this depth point, counterclockwise cutting is done along inner ring pad outer ring profile, this cutting arc length is the half of arc length between two depth points, cutting area is done the pull-up gained on vertical direction, the pull-up process direction of locking pin is the rear in face, counterclockwise cutting step place again.
As to further improvement of the utility model, the quantity of described locking pin is 4 ~ 6.
As to further improvement of the utility model, the lower end surface after the pull-up of described locking pin and between face, inner ring pad place the scope of maximum angle α be 30 ° ~ 45 °.
After the utility model adopts said structure, in the process that screw oppositely exits being subject to extraneous vibration, can be stuck by the reverse lines of some locking pin, thus play fabulous retaining effect, in addition, fastening foot can prevent washer body from rotating with coordinating of keyway on screw, makes the retaining effect locking pin reach best; Locking pin after cutting and pull-up step with inner ring pad not in one plane, when nut tightens, some locking pin will give nut the great elastic force contrary with tightening direction, thus make nut very fastening.
Accompanying drawing explanation
Below in conjunction with the embodiment in accompanying drawing, the utility model is described in further detail, but do not form any restriction of the present utility model.
Fig. 1 is plan view of the present utility model.
Fig. 2 is structural representation of the present utility model.
In figure: 1-fastening foot; 2-inner ring pad; 3-locks pin.
Embodiment
Consult shown in Fig. 1 and Fig. 2, dynamic device components and parts packing ring, comprises washer body, and washer body comprises again fastening foot 1, inner ring pad 2 and some locking pin 3.
Fastening foot 1 is connected with inner ring pad 2 inner ring, and is semi-cylindrical hill, its shape of cross section and washer body the keyway overlapped on screw match, like this, no matter how external environment condition jolts or vibrates, and washer body all can not do the rotary motion around screw.
Some locking pin 3 are all connected with inner ring pad 2 outer ring, lock the outer ring of pin 3 by the outer shroud pad be connected with inner ring pad 2 outer ring after some deciles, the direct cutting through the center of circle is done at equal diversion point, this depth of cut is equal with inner ring pad 2 ring width, again by this depth point, counterclockwise cutting is done along inner ring pad 2 outer ring profile, this cutting arc length is the half of arc length between two depth points, cutting area is done the pull-up gained on vertical direction, the pull-up process direction of locking pin 3 is the rear in face, counterclockwise cutting step place again.The quantity of above-mentioned some locking pin 3 is 4 ~ 6, and in addition, the scope locking maximum angle α between the lower end surface after pin 3 pull-up and face, inner ring pad 2 place is 30 ° ~ 45 °.
After the utility model connection screw is installed to the mounting hole of components and parts, when screw oppositely exits being subject to extraneous vibration, the reverse lines of some locking pin 3 can be stuck by it, screw cannot be exited from components and parts mounting hole, in addition, the key that there is fastening foot 1 between washer body with screw coordinates, and makes the retaining effect locking pin 3 reach best like this.In addition, locking pin 3 after cutting and pull-up step with inner ring pad 2 not in one plane, after screw tightens, some locking pin 3 will give nut the great elastic force contrary with tightening direction, thus make it more fastening.Described on end, the utility model has stopped the loosening and problem that comes off that device components uses for a long time in dynamic environment.
