Specific embodiment
Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.
As shown in Figure 1 to Figure 3, a kind of rubber sheet gasket provided in the present embodiment, including annular gasket 1, annular gasket 1
Center offers the perforative mounting hole 11 for installing part, and rubber sheet gasket further includes four positioning components 2, annular gasket 1
Outer edge surface offer four equidistant grooves 12, four positioning components 2 are embedded respectively in four grooves 12.Rubber in order to prevent
Glue gasket loosens movement because compression is arched upward in sealing pipeline.Further, four positioning components 2 can be connected in pipeline
Wall, when part, which passes through mounting hole 11 and annular gasket 1, to be interference fitted, annular gasket 1 is simultaneously by part and inner wall of the pipe
Pressure, at this point, four circumferentially equally distributed positioning component 2 can limit the movement of annular gasket 1, prevent rubber sheet gasket from existing
Movement is loosened because compression is arched upward when sealing pipeline, and then improves the leakproofness of part.It is fixed in order to which positioning component 2 may be implemented
Bit function.Further, positioning component 2 includes top flat 21, spring 22, the fixed company in one end of top flat 21 and one end of spring 22
It connects, the other end of spring 22 is fixed on the bottom of groove 12, and top flat 21 can make stretching motion along groove 12.Top flat 21 and pipeline
One end of 3 inner walls contact has card convex 211, and card convex 211 is clamped with 31 phase of card slot on the inner wall for being provided with pipeline 3.Mounting ring
When shape gasket 1, pressure can be applied to top flat 21,22 stress of spring is compressed at this time, and card convex 211 is driven to be collapsible into groove 12
Interior, when top flat 21 is close to card slot 31,22 elastic reset of spring drives the pop-up of card convex 211 to be simultaneously clamped with 31 phase of card slot, makes to position
Component 2 realizes positioning function.
Pressure when being contacted for yielding rubber gasket and remaining components.Further, the upper surface of annular gasket 1 and
Lower surface circumferentially offers the equidistant a plurality of cavities 15 for compensator or trimmer pressure.When components touch annular gasket 1
When surface makes, cavity 15 has cavity, and pressure when can be squeezed with yielding rubber gasket prevents rubber sheet gasket stress deformation
And fail, it prolongs its service life.
For further rubber sheet gasket impact force suffered in part.Further, the upper surface of annular gasket 1 and under
Surface is bonded with multiple salient points 16 for impact force suffered by buffering spacer.Salient point 16 protrudes the surface of annular gasket 1 and tool
There is certain elasticity, when impact of the rubber sheet gasket by part, can directly be touched with part to avoid the surface of annular gasket 1,
Salient point 16 is squeezed at this time, can offset and balance part of impact force suffered by rubber sheet gasket, and then plays the work of bumper and absorbing shock
With preventing rubber sheet gasket stress deformation and fail, prolong its service life.
In order to make the better tightness of rubber sheet gasket.Further, the hole wall of mounting hole 11 is equipped with multiple inner seal rings
13, it is parallel to each other between multiple inner seal rings 13 and is spaced setting.The outer edge surface of annular gasket 1 is equipped with multiple exterior seal rings
14, it is parallel to each other between multiple exterior seal rings 14 and is spaced setting.After rubber sheet gasket is installed, the pressure between mounting hole 11 and part
Power allows inner seal ring 13 to be close to part, reaches interference fit, and the pressure between exterior seal ring 14 and the inner wall of pipeline 3 makes outer
Sealing ring 14 can be close to part, reach interference fit, through the above process, make the better tightness of rubber sheet gasket.
In order to enhance the connectivity robustness of card convex 211 Yu card slot 31.Further, the surface of card convex 211 is for increasing
The frosting of coefficient of friction.Card convex 211 is frosting, increases coefficient of friction, and then is increased when card convex 211 is contacted with card slot 31
Frictional force, it is difficult to slide after being clamped card convex 211 and card slot 31 and deviate detent, and then enhance the company of card convex 211 and card slot 31
Connect fastness.
The utility model is described with reference to the preferred embodiments, and those skilled in the art know, is not departing from this reality
In the case where with novel spirit and scope, various changes or equivalence replacement can be carried out to these features and embodiment.This reality
It is not limited to the particular embodiment disclosed with novel, other embodiments fallen into claims hereof all belong to
In the range of the utility model protection.
