Abstract
The utility model discloses a kind of compound gasket, comprise Upper gasket and lower levelling plate, described Upper gasket is coaxially arranged at above lower levelling plate, described Upper gasket is coaxially arranged with a upper groove on the lower end surface of lower levelling plate, described lower levelling plate is coaxially arranged with a low groove on the upper-end surface of Upper gasket, described is upper, low groove is built with disc spring, described disc spring is made up of upper spring and lower spring, the upper-end surface of upper spring is curved arches and abuts with the bottom surface of upper groove, the lower end surface of upper spring is provided with ripple groove, the upper-end surface correspondence of lower spring is provided with the corrugated projection plugging laminating with ripple groove on upper spring, the lower end surface of lower spring is also curved arches and abuts with the bottom surface of low groove, the upper-end surface of described Upper gasket and the lower end surface of described lower levelling plate are also provided with anti-slip veins.By adopting said structure, the anti-loosing effect of compound gasket effectively can be promoted.
Description
Technical field
The utility model relates to a kind of pad, is specifically related to a kind of combined type pad.
Background technique
Pad is a kind of conventional mechanical fitting, its structure is mostly circular, usually be loaded between screw bolt and nut and play locking seal action, but because existing pad is integrate shaped type structure, and its upper-end surface and lower end surface are plane, therefore, when equipment shakes running state through repeatedly installing and removing or being in, the anti-loosing effect of existing pad is poor, thus the reliability that the equipment that greatly affects normally runs.
Summary of the invention
For the deficiencies in the prior art, the utility model provides the better compound gasket of a kind of anti-loosing effect.
For achieving the above object, the utility model provides a kind of compound gasket, comprise Upper gasket and lower levelling plate, described Upper gasket is coaxially arranged at above lower levelling plate, described Upper gasket is coaxially arranged with a upper groove on the lower end surface of lower levelling plate, described lower levelling plate is coaxially arranged with a low groove on the upper-end surface of Upper gasket, described is upper, low groove is built with disc spring, described disc spring is made up of upper spring and lower spring, the upper-end surface of upper spring is curved arches and abuts with the bottom surface of upper groove, the lower end surface of upper spring is provided with ripple groove, the upper-end surface correspondence of lower spring is provided with the corrugated projection plugging laminating with ripple groove on upper spring, the lower end surface of lower spring is also curved arches and abuts with the bottom surface of low groove, the upper-end surface of described Upper gasket and the lower end surface of described lower levelling plate are also provided with anti-slip veins.
The beneficial effects of the utility model are: adopt said structure, because the utility model is provided with disc spring between described Upper gasket and lower levelling plate, therefore, under the effect of described disc spring, upper and lower pad can be made to keep better pretightening force, thus greatly promote anti-loosing effect.Simultaneously because described disc spring is made up of upper spring and lower spring, and linked together by the corresponding matching of described ripple groove and corrugated projection, therefore make described disc spring can with the structure function of bilayer between upper and lower pad, elastic performance is better, longer service life, and the corresponding curved setting of arching in the lower end surface of the upper-end surface of described upper spring and lower spring, also can promote the pretightening force between upper and lower pad further, thus promote anti-loosing effect further.In addition, the lower end surface of the upper-end surface of described Upper gasket and described lower levelling plate arranges anti-slip veins, also effectively can promote the overall anti-loosing effect of compound gasket.
The utility model can be set to described anti-slip veins preferred S shape structure further, and radially arranges.Adopt said structure, the preferred said structure of described anti-slip veins and layout, non-skid property will promote greatly.
The utility model also can be set to described lower levelling plate further and also be evenly distributed in multiple projection around described low groove on the upper-end surface of Upper gasket, and the centerline axis parallel of the central axis of described projection and upper and lower pad, the corresponding through hole be provided with for described projection insertion on described Upper gasket, each projection is also set with an elastomer block, and described elastomer block is corresponding between Upper gasket lower end surface and lower levelling plate upper-end surface.
Adopt said structure; coordinated with the grafting of through hole by described projection; upper and lower pad can be made to be combined into one better; and the setting of described elastomer block; then can make between upper and lower pad, there is a buffering; thus effectively avoid upper and lower pad because fitting instantaneously by acting on more energetically, and then available protecting is formed to disc spring.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the plan view of Fig. 1.
Embodiment
As Fig. 1, a kind of compound gasket is given shown in 2, comprise Upper gasket 1 and lower levelling plate 2, described Upper gasket 1 is coaxially arranged at above lower levelling plate 2, described Upper gasket 1 is coaxially arranged with a upper groove 111 on the lower end surface 11 of lower levelling plate 2, described lower levelling plate 2 is coaxially arranged with a low groove 211 on the upper-end surface 21 of Upper gasket 1, described upper groove 111, low groove 211 is built with disc spring 3, described disc spring 3 is made up of upper spring 31 and lower spring 32, the upper-end surface 311 of upper spring 31 is curved arches and abuts with the bottom surface of upper groove 111, the lower end surface 312 of upper spring 31 is provided with ripple groove, it is protruding that upper-end surface 321 correspondence of lower spring 32 is provided with the corrugated plugging laminating with ripple groove on upper spring 31, the lower end surface 322 of lower spring 32 is also curved arches and abuts with the bottom surface of low groove 211, the upper-end surface 12 of described Upper gasket 1 and the lower end surface 22 of described lower levelling plate 2 are also provided with anti-slip veins 4, described anti-slip veins 4 is S shape structure preferably, and radially arrange.Described lower levelling plate 2 is also evenly distributed in multiple projection 212 around described low groove 211 on the upper-end surface 21 of Upper gasket 1, and the centerline axis parallel of the central axis of described projection 212 and Upper gasket 1, lower levelling plate 2, the corresponding through hole 13 be provided with for described projection 212 insertion on described Upper gasket 1, each projection 212 is also set with an elastomer block 5, and described elastomer block 5 correspondence is between Upper gasket lower end surface 11 and lower levelling plate upper-end surface 21.By adopting said structure, the utility model provides the better compound gasket of a kind of anti-loosing effect.
