Abstract
The utility model discloses a simple and easy two -way lock washer, it is used for preventing that the nut pine on the flange face from taking off, it contains: the packing ring main part, its pad is established flange face and nut between, this packing ring main part contains an upper surface and a lower surface, first locking portion, it sets up on the upper surface of packing ring main part, die the tight lock of nut side subsides, second locking portion, it sets up on the lower surface of packing ring main part, paste tight lock with the flange surface and die. Its advantage is: the utility model provides a brand -new locking structure of taking off, can firmly pinning the messenger with nut and flange, not produce the displacement each other not hard up, use reliable, and low cost.
Description
Technical field
The utility model relates to engineering element technical field, is specifically related to a kind of simple bidirectional lock washer.
Background technique
Generally choice for use packing ring in the connection procedure of fastening piece, one is to expand area of contact, the stress reducing fastening force is concentrated, prevent workpiece damage, two is can not scratch fastener body when tightening or get loose nut, and some packing rings with special anti-loose function often complex structure, expensive.
Model utility content
The purpose of this utility model is to provide a kind of simple bidirectional lock washer, and it has anti-loose function, and with low cost.
In order to achieve the above object, the utility model is achieved through the following technical solutions:
A kind of simple bidirectional lock washer, for preventing the nut on flanged surface from getting loose, is characterized in that, comprise:
Washer body, its pad is located between described flanged surface and nut, and this washer body comprises a upper surface and a lower surface;
First tight lock part, it is arranged on the upper surface of described washer body, is adjacent to locked by nut side;
Second tight lock part, it is arranged on the lower surface of described washer body, is adjacent to by flange outer face locked.
Above-mentioned simple bidirectional lock washer, wherein:
Described washer body is the thin rounded flakes with center hole, the local edge of this thin rounded flakes upwards vertical curve to form the first described tight lock part.
Above-mentioned simple bidirectional lock washer, wherein:
The second described tight lock part is a strip thin slice, and it is vertically set on the lower surface of described washer body, and its one end correspondence connects the excircle of described washer body.
Above-mentioned simple bidirectional lock washer, wherein:
The second described tight lock part and described washer body are formed in one structure.
The utility model compared with prior art has the following advantages: which propose a kind of brand-new anti-loose structure, nut and flange firmly can be pinned to make not produce displacement each other and loosen, and uses reliable, and with low cost.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is example structure schematic diagram of the present utility model;
Fig. 3 is the overall structure schematic diagram of the utility model when not installing.
Embodiment
Below in conjunction with accompanying drawing, by describing a preferably specific embodiment in detail, the utility model is further elaborated.
As shown in Figure 1, a kind of simple bidirectional lock washer, for preventing the nut 3 on flanged surface from getting loose, it comprises: washer body 1, and its pad is located between described flanged surface and nut 3, and this washer body 1 comprises a upper surface and a lower surface; First tight lock part 11, it is arranged on the upper surface of described washer body 1, is adjacent to locked by nut 3 side; Second tight lock part 12, it is arranged on the lower surface of described washer body 1, is adjacent to locked by flange 3 outer surface.
Described washer body 1 for having the thin rounded flakes of center hole, the local edge of this thin rounded flakes upwards vertical curve to form the first described tight lock part 11.The second described tight lock part 12 is a strip thin slice, and it is vertically set on the lower surface of described washer body 1, and its one end correspondence connects the excircle of described washer body 1.
As shown in Figure 2, described second tight lock part 12 and described washer body 1 are formed in one structure, as shown in Figure 3, during use, the same with plain washer, between the flanged surface first lock washer being placed in nut 5 and flange 3, and be screwed into nut 5 successively with stud 4, the center hole of washer body 1 and flange 3, after reaching suitable moment of torsion, the second tight lock part 12 of lock washer is noted to be placed in outside flange 3, and knock this second tight lock part 12 downwards, make it to bend and be adjacent to the outer surface of flange 3, then the local edge of washer body 1 is upwards knocked, make it to bend and be adjacent to a side of nut 5, just make nut 5 locked with the position of flange 3 by the first tight lock part 11 and the second tight lock part 12 like this, lock washer only otherwise deform or fracture, nut 5 would not loosen, serve anti-loose effect.
Although content of the present utility model has done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to restriction of the present utility model.After those skilled in the art have read foregoing, for multiple amendment of the present utility model and substitute will be all apparent.Therefore, protection domain of the present utility model should be limited to the appended claims.
