Abstract
The invention discloses a composite gasket which comprises an upper gasket and a lower gasket. The upper gasket is arranged on the upper side of the lower gasket, and through holes are formed in the center of the upper gasket and the center of the lower gasket; an annular protruding portion is formed in the lower surface of the upper gasket; and an annular groove is formed in the upper surface of the lower gasket; the size and shape of the protruding portion are the same as those of the groove, and the protruding portion is arranged in the groove. According to the composite gasket, due to the fact that the upper gasket and the lower gasket can rotate relatively in a matched mode, when bolts or nuts are screwed, the bolts or the nuts only drive the upper gasket or the lower gasket to rotate, then the lower gasket or the upper gasket is static relative to a piece to be connected, and surface abrasion of the piece to be connected is avoided; the protruding portion of the upper gasket is matched with the groove of the lower gasket so as to avoid dislocation between the upper gasket and the lower gasket; the contacting faces of the upper gasket and the lower gasket can be more smooth through surface processing, or lubricant can be added between the upper gasket and the lower gasket, and therefore a better effect can be achieved.
Description
Technical field
The present invention relates to a kind of packing ring, particularly a kind of composite-gasket of surface abrasion of the screw hole place that can reduce connected piece.
Background technique
Between screw or nut and connected piece, usually be lined with the wearing and tearing that packing ring reduces the connected piece surface, but when screw or nut are screwed into the end, needing to continue reinforcing screws screw or nut, at this moment the frictional force of screw or nut and packing ring reaches maximum, if the surface of connected piece is comparatively smooth, at this moment the frictional force between packing ring and screw or nut will be greater than the frictional force between packing ring and connected piece, cause packing ring to follow screw or nut rotation, make the surface of packing ring and connected piece produce sliding friction, the surface of wearing and tearing connected piece.
Summary of the invention
Technical problem for above-mentioned existence the objective of the invention is: the composite-gasket that has proposed a kind of surface abrasion of the screw hole place that can reduce connected piece.
Technical solution of the present invention is achieved in that a kind of composite-gasket, comprises upper gasket, lower gasket; Described upper gasket is arranged on the upside of lower gasket, and the center of upper gasket and lower gasket is provided with through hole; On the lower surface of described upper gasket, be provided with the lug boss of annular; On the upper surface of described lower gasket, be provided with the groove of annular; Described lug boss is identical with the size shape of groove, and lug boss is arranged in groove.
Preferably, between described lug boss and groove, be provided with oiling agent.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Composite-gasket of the present invention, by the upper gasket that can produce relative rotation and the cooperation of lower gasket, make screw or nut when screwing, screw or nut only drive upper gasket or lower gasket rotates, another is static with respect to connected piece, has avoided the surface abrasion of connected piece; The cooperation of the lug boss of upper gasket and the groove of lower gasket avoids upper gasket and lower gasket to produce dislocation; The surface of contact of upper gasket and lower gasket can become Paint Gloss by surface treatment, or adds oiling agent between upper gasket and lower gasket, thereby reaches better effect.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the three-dimensional exploded view of a kind of composite-gasket of the present invention;
Accompanying drawing 2 is the sectional view of a kind of composite-gasket of the present invention;
Wherein: 1, upper gasket; 2, lower gasket; 3, lug boss; 4, groove; 5, oiling agent.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described.
As accompanying drawing 1,2, be depicted as a kind of composite-gasket of the present invention, comprise upper gasket 1, lower gasket 2; Described upper gasket 1 is arranged on the upside of lower gasket 2, and the center of upper gasket 1 and lower gasket 2 is provided with through hole; On the lower surface of described upper gasket 1, be provided with the lug boss 3 of annular; On the upper surface of described lower gasket 2, be provided with the groove 4 of annular; Described lug boss 3 is identical with the size shape of groove 4, and lug boss 3 is arranged in groove 4; Between described lug boss 3 and groove 4, be provided with oiling agent 5.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Composite-gasket of the present invention, by the upper gasket 1 that can produce relative rotation and the cooperation of lower gasket 2, make screw or nut when screwing, screw or nut only drive upper gasket 1 or lower gasket 2 rotates, another is static with respect to connected piece, has avoided the surface abrasion of connected piece; The cooperation of the lug boss 3 of upper gasket 1 and the groove 4 of lower gasket 2 avoids upper gasket 1 and lower gasket 2 to produce dislocation; The surface of contact of upper gasket 1 and lower gasket 2 can become Paint Gloss by surface treatment, or adds oiling agent 5 between upper gasket 1 and lower gasket 2, thereby reaches better effect.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the person skilled in the art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
