Abstract
The utility model discloses an anti -loosing spacer, including flaky gasket body, set up the through -hole that supplies the connecting piece to pass on this gasket body, its technical essential lies in: the arch has one -way anti -skidding structure on the gasket body, and this antiskid structure sets up in the gasket body is integrative, aims at providing an anti -loosing spacer who has one -way anti -skidding effect.
Description
Technical field
The utility model relates to a kind of hardware, and more particularly it relates to a kind of pad.
Background technique
Pad is widely used in the connection of mechanical structure, is mainly used in strengthening the mechanical seal between mechanical component.Along with the improved application of bolt arrangement, check washer arises at the historic moment, occurring as this elastic deformability of having of spring pad, to have prevented thread looseness check washer for providing opposition to bolt, and along with the quickening of process of industrialization, the function of pad is also gradually towards more diversely developing.
At present, be disclose a kind of improved mat for installing subframe in the Chinese invention patent of CN201110453950.6 in the patent No., and comprise the automobile of this improved mat, and relate to a kind of auxiliary frame installation method utilizing improved mat further.The main body of this improved mat is made up of Circular Rigid plate, via hole is provided with in the middle part of described plate, through described via hole, described improved mat is anchored on described subframe and automotive body for making fastening piece, the periphery of described improved mat is provided with for by the buckle of described improved mat preposition on described subframe, and the both sides of described improved mat are provided with the corresponding projection in position, the shape of described projection all forms a spherical part.
As improved mat disclosed in above-mentioned patent, it utilizes the Contact being raised in mechanical component at gasket surface, has certain elastic strain ability on the one hand, plays anti-loosing effect; On the other hand by the protruding contact friction force increasing pad and mechanical component surface, play skidproof effect.But be frequently in the mechanical connecting structure of state of wear at some, often need unidirectional skidproof effect, and the existing check washer of such effect is still difficult to realize.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of check washer with unidirectional skidproof effect.
For achieving the above object, the utility model provides following technological scheme: a kind of check washer, comprise the shim body of sheet, this shim body offers the through hole passed for link, wherein: described shim body projection has unidirectional anti-skid structure, and this anti-skid structure is wholely set in shim body.
By adopting technique scheme, prevent pad from producing the slip towards specifying braking direction on mechanical component surface by unidirectional anti-skid structure, can apply on the one hand need to keep unidirectional fastening mechanical connection, also can link with unidirectional tooth on the other hand and to use as unidirectional bounding means, simple, facilitate.
The utility model is set to further: the side of described shim body is brake side, and opposite side is along dynamic side, and described anti-skid structure is by suitable dynamic side convex closure that is initial, that tilt towards brake side.
By adopting technique scheme, the convex closure tilted by unified direction makes described shim body from braking sideslip to along dynamic side, but can cannot break away to brake side from along dynamic, effectively realizes the one-way brake of improved mat, unidirectional spacing.
The utility model is set to further: described convex closure is provided with multiple, and convex closure is disposed side by side between brake side and suitable dynamic side.
By adopting technique scheme, the convex closure be set up in parallel is utilized effectively to strengthen the unidirectional restraining ability of improved mat.
The utility model is set to further: the volume of described convex closure increases to brake side successively by along dynamic side.
By adopting technique scheme, due to when resisting the sliding force of braking direction, brake side starts stressed at first, so the convex closure volume of brake side is large, the intensity of its strength is high, not easily produces distortion, thus makes the unidirectional restraining ability of improved mat more stable, lasting, durable.
Accompanying drawing explanation
Fig. 1 is the schematic perspective view of the utility model embodiment check washer;
Fig. 2 is the plan view of the utility model embodiment check washer;
Fig. 3 is the schematic cross-section of the utility model embodiment check washer.
Reference character: 1, shim body; 2, through hole; 3, anti-skid structure (convex closure); 4, brake side; 5, along dynamic side.
Embodiment
Below in conjunction with Figure of description, the utility model embodiment check washer is described further.
Embodiment one: a kind of check washer, comprise the shim body 1 of sheet, shim body 1 is preferably made up of the good manganese steel of elastic performance, this shim body 1 offers the through hole 2 passed for link, wherein: described shim body 1 projection has unidirectional anti-skid structure 3, and this anti-skid structure 3 is wholely set in shim body 1.Concrete, known see Figure of description 2, the side of described shim body 1 is brake side 4, and opposite side is along dynamic side 5, and described anti-skid structure 3 is by suitable dynamic side 5 convex closure 3 that is initial, that tilt towards brake side 4.Utilize wedge shape, topple over the convex closure 3 of shape towards brake side 4 and form unidirectional anti-skid structure 3, described shim body 1 cannot be slided to along dynamic side 5 from brake side 4, but brake side 4 can be slided to from along dynamic side 5, effectively realize the one-way brake of improved mat, unidirectional spacing.
Embodiment two: a kind of check washer, comprise the shim body 1 of sheet, this shim body 1 offers the through hole 2 passed for link, wherein: described shim body 1 projection has unidirectional anti-skid structure 3, this anti-skid structure 3 is wholely set in shim body 1, the side of described shim body 1 is brake side 4, and opposite side is along dynamic side 5, and described anti-skid structure 3 is by suitable dynamic side 5 convex closure 3 that is initial, that tilt towards brake side 4.Described convex closure 3 is provided with multiple, and convex closure 3 is disposed side by side between brake side 4 and suitable dynamic side 5.The convex closure 3 be set up in parallel is utilized effectively to strengthen the unidirectional restraining ability of improved mat.
In the present embodiment two, also arrange further: the volume of described convex closure 3 increases successively by along dynamic side 5 to brake side 4.Due to when resisting the sliding force of braking direction, brake side 4 starts stressed at first, so convex closure 3 volume of brake side 4 is large, the intensity of its strength is high, not easily produces distortion, thus makes the unidirectional restraining ability of improved mat more stable, lasting, durable.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, all within design concept of the present utility model, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
