The hole sealing structure is good in sealing performance, simple in structure, easy to machine and easy to install.
Description
Technical field
The utility model relates to field of sealing technology, particularly, relates to a kind of sealing configuration of hole.
Background technique
Sealing can be divided into static seal and the large class of motive sealing two.Sealing is to prevent that fluid or solid particle are from leaking and prevent component or the measure that introduced contaminants is invaded machinery equipment inside as dust and moisture etc. between adjacent junction plane.
At present, the structure that adopts bearing pin interference to press-fit in the sealing of small space inner via hole more, the form that is coated with sealer by press-assembling surface seals, but, this structure is due to reasons such as quality of processing, interference press-fit, the oil gas of mixed oil and gas one side is usually leaked to opposite side, causes the serious consequences such as gas leak of the oil leakage.
In view of this, a kind of sealing configuration of novel hole need to be provided.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of sealing configuration of hole, and the sealing configuration in this hole has good sealing property, and simple in structure, and manufacturing is easy, is easy to install.
For above-mentioned technical problem, the utility model provides a kind of sealing configuration of hole, the sealing configuration in this hole comprises elastic seal ring and for interference, is press fit into the link block in described hole, and described link block is provided with for coordinating described hole to compress the boss of described elastic seal ring.
Preferably, described link block comprises pin main body, and described boss is that described boss has center line along the continuous projection of the periphery of described pin main body, and the center line of described boss and described pin main body is coaxial.
Preferably, described pin main body is cylindrical.
Preferably, along the periphery of described pin main body, the distance of described boss radial protrusion is identical.
Preferably, described link block is integrated part.
Preferably, described elastic seal ring is rubber elasticity seal ring.
Preferably, described hole is provided with for the chamfering of described elastic seal ring is installed with respect to a side of described boss.
The sealing configuration in hole of the present utility model is owing to comprising elastic seal ring and being press fit into the link block in described hole for interference, described link block is provided with for coordinating described hole to compress the boss of described elastic seal ring, thereby when press-fiting by interference and sealing, utilize described link block described elastic seal ring to be pressed between the described boss of hole and described link block, gap between described link block and described hole is compensated to sealing, further improve the sealing of the sealing configuration in hole of the present utility model, meanwhile, the sealing configuration easy processing in hole of the present utility model, simple in structure, be easy to install, there is good popularizing prospect.
Other feature and advantage of the present utility model partly in detail are described the embodiment subsequently.
Accompanying drawing explanation
Accompanying drawing is to be used to provide further understanding of the present utility model, and forms a part for specification, is used from explanation the utility model, but does not form restriction of the present utility model with embodiment one below.In the accompanying drawings:
Fig. 1 is according to the schematic diagram of the sealing configuration in the hole of embodiment of the present utility model.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.Should be understood that, embodiment described herein only, for description and interpretation the utility model, is not limited to the utility model.
The utility model provides a kind of sealing configuration of hole, particularly, shown in Figure 1, the sealing configuration in this hole comprises elastic seal ring 2 and for interference, is press fit into the link block 3 in described hole 1, and described link block 3 is provided with for coordinating described hole 1 to compress the boss 4 of described elastic seal ring 2.
It should be noted that, the specific constructive form of described elastic seal ring 2, described link block 3, described boss 4 can arrange as required, within these all belong to technical conceive scope of the present utility model.
In above-mentioned basic technical scheme of the present utility model, owing to comprising elastic seal ring 2 and being press fit into the link block 3 in described hole 1 for interference, described link block 3 is provided with for coordinating described hole 1 to compress the boss 4 of described elastic seal ring 2, thereby when press-fiting by interference and being coated with sealer sealing on link block 3, utilize described link block 3 that described elastic seal ring 2 is pressed between described hole 1 and the described boss 4 of described link block 3, gap between described link block 3 and described hole 1 is compensated to sealing, further improve the sealing of the sealing configuration in hole of the present utility model, meanwhile, the sealing configuration easy processing in hole of the present utility model, simple in structure, be easy to install, there is good popularizing prospect.
In the sealing configuration in hole of the present utility model, preferably, described link block 3 comprises pin main body, described boss 4 is along the continuous projection of the periphery of described pin main body, described boss 4 has center line, and the center line of described boss 4 and described pin main body is coaxial, the protruding boss 4 continuous along the periphery of described pin main body can intactly be pressed on described elastic seal ring 2 between described hole and the described boss 4 of described link block 3, guarantee the sealing of the sealing configuration in hole, the center line of described boss 4 and described pin main body is coaxially convenient to workman's manufacturing.
In the sealing configuration in hole of the present utility model, particularly, described pin main body is cylindrical, and tubular pin main body is easy to manufacture, but also adapts to the installation in most of holes, has good applicability.
In above-mentioned basic technical scheme of the present utility model, along the periphery of described pin main body, the distance of described boss 4 radial protrusions identical (being that described boss 4 is cylindrical body), the boss 4 that the distance of radial protrusion is identical is simple in structure, easy to manufacture, be conducive to cost-saving.
Certainly, the specific constructive form of described boss 4 must be for the distance of the outer periphery projection along described pin main body is identical, and for example as required, described boss 4 can be square body shape, thereby is convenient to the sealing configuration that user installs described hole.
In the sealing configuration in hole of the present utility model, preferably, described link block 3 is integrated part, and the described link block of integral type can be saved described boss 4 is connected in to the operation on described link block 3, is conducive to cost-saving.
