Abstract
The utility model relates to a concentric ring washer, comprising a washer body, a plurality of concentric and ring-shaped bumps disposed on the end face of the washer body, and a positioning hole which is disposed in the washer body and is coaxial to the washer body. Bumps at the outermost ring are distributed at the outermost edge of the washer body. The concentric ring washer is advantageous in that a plurality of ring-shaped bumps are disposed on the washer body, and when the washer is deformed by the extruding of connecting pieces like screws, the ring-shaped bumps can fill gaps generated by deformation, and thereby waterproof effect can be greatly improved.
Description
Technical field
The utility model relates to a kind of concentric circle pad.
Background technique
Existing pad is cylindric, and equal level and smooth disc on its both ends of the surface can distortion behind the pressure that is subjected to the link such as screw, may produce the slit between pad and link, affects waterproofing effect.
Summary of the invention
The utility model purpose provides preferably concentric circle pad of a kind of waterproofing effect.
In order to achieve the above object, the technological scheme that the utility model adopts is: a kind of concentric circle pad, it comprises shim body, it is characterized in that: it also comprises how concentric annular projection on the end face that is arranged on described shim body, be opened on the shim body positioning hole with the coaxial setting of shim body, and the outmost turns projection is distributed in the outer of shim body.
The diameter of described shim body is 1～2cm, and thickness is 2～3mm.
The height of described projection is 1～2mm.
Described annular projection spaced set.
Owing to adopt technique scheme, the utlity model has following advantage: the utility model arranges the multi-ring annular projection in shim body, be subjected to the extruding generation distortion of the links such as screw at pad after, annular projection can be filled up the gap that deformation produces, and has greatly improved waterproofing effect.
Description of drawings
Accompanying drawing 1 is three-dimensional view of the present utility model;
Accompanying drawing 2 is plan view of the present utility model;
Accompanying drawing 3 is the A-A sectional view of accompanying drawing 2;
Wherein: 1, shim body; 2, annular projection; 3, positioning hole.
Embodiment
Below in conjunction with accompanying drawing, the preferred specific embodiment of the utility model is described:
As shown in the figure, this concentric circle pad comprises shim body 1, is arranged on how concentric annular projection 2 on the end face of described shim body 1, is opened on the shim body 1 positioning hole 3 with shim body 1 coaxial setting.The diameter of described shim body 1 is 1.5cm, and thickness is 3mm; Described projection 2 is totally three circles, highly is 1mm and spaced set, and outmost turns projection 2 is distributed in the outer of shim body 1.
During installation, shim body 1 stressed link extrusion-deformation, the projection 2 that is arranged on the shim body 1 can be filled up issuable slit when being out of shape, and has improved waterproofing effect.
Above-mentioned combination is illustrated the utility model institute preferred embodiment; but above-described embodiment can not be interpreted as the restriction to the utility model protection domain, and all equivalences of doing according to the utility model Spirit Essence change or modification all should be encompassed within the protection domain of the present utility model.
