Abstract
The utility model relates to a composite gasket, which comprises an upper gasket and a lower gasket, wherein the upper gasket is arranged on the upper side of the lower gasket, through holes are arranged on the centers of the upper gasket and the lower gasket, a ring-shaped raised portion is arranged on the lower surface of the upper gasket, a ring-shaped groove is arranged on the upper surface of the lower gasket, the sizes and the shapes of the ring-shaped raised portion and the ring-shaped groove are same, and the ring-shaped raised portion is arranged in the ring-shaped groove. The composite gasket enables a screw or a nut just to drive the upper gasket or the lower gasket to rotate when the screw or the nut is screwed by matching the upper gasket and the lower gasket which can relatively rotate, another one is static relative to a connected part, and the surface of the connected part is prevented from being worn. The upper gasket and the lower gasket are prevented from misplacing by matching the ring-shaped raised portion of the upper gasket and the ring-shaped groove of the lower gasket. A contact surface of the upper gasket and the lower gasket can be smoother by being processed, or lubricant is added between the upper gasket and the lower gasket, thereby achieving better effect.
Description
Technical field
The utility model 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, be conventionally lined with the wearing and tearing that packing ring reduces 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 is by the frictional force being greater than 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.
Model utility content
The utility model object is the composite-gasket that a kind of surface abrasion of the screw hole place that can reduce connected piece is provided in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: 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 annular lug boss; On the upper surface of described lower gasket, be provided with annular groove; 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 utility model compared with prior art has following advantages:
The composite-gasket of the utility model scheme, 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 to rotate, 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.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
The three-dimensional exploded view that accompanying drawing 1 is a kind of composite-gasket described in the utility model;
The sectional view that accompanying drawing 2 is a kind of composite-gasket described in the utility model;
Wherein: 1, upper gasket; 2, lower gasket; 3, lug boss; 4, groove; 5, oiling agent.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Accompanying drawing 1-2 is a kind of composite-gasket described in the utility model, comprises 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 annular lug boss 3; On the upper surface of described lower gasket 2, be provided with annular groove 4; 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 utility model compared with prior art has following advantages:
The composite-gasket of the utility model scheme, 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 to rotate, 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.
Below be only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, within all dropping on the utility model rights protection scope.
