Description
Technical field
It the utility model is related to a kind of gasket, and in particular, to a kind of internal diameter adjustable type gasket.
Background technology
Gasket is the mechanical seal between two objects, usually to prevent from being under pressure between two objects, burn into and
Pipeline expands with heat and contract with cold leakage naturally.Since machining surface can not possibly be perfect, scrambling can be filled up using gasket.Pad
Piece is usually made of flaky material, such as packing paper, rubber, silicon rubber, metal, cork, felt, neoprene, nitrile rubber, glass
Fiber or plastic polymer (such as polytetrafluoroethylene (PTFE)).Existing gasket, its internal diameter size immobilize, it is impossible to adapt to
The screw rod of various outer diameter.
Utility model content
The utility model is in order to solve drawbacks described above and deficiency existing in the prior art, there is provided a kind of internal diameter adjustable type
Gasket, can adjust the internal diameter of the through hole passed through for bolt.
In order to solve the above technical problems, the utility model provides a kind of internal diameter adjustable type gasket, including shim body, extension
Portion and internal diameter adjustment portion, the extension are fixed in the shim body, and the extension and shim body place
Horizontal plane is in setting angle；The internal diameter adjustment portion includes adjustment unit and telescopic rod, and the quantity of the adjustment unit is at least 2
A, the both ends of the telescopic rod are respectively welded on the outer wall of the adjustment unit and the inner wall of the shim body, and described
Telescopic rod is positioned by positioning component, and the positioning component includes the elastic button and location hole being arranged on telescopic rod,
After the telescopic rod elongates or shortens, it is connected in the location hole and is fixed on the positioning by elastic button；It is all to adjust list
Member is end to end to surround a through hole passed through for bolt.
Further, the side wall of two neighboring adjustment unit is equipped with connection component, and the connection component includes setting one
Circular groove and the protrusion being arranged on another adjustment unit side wall on adjustment unit side wall, groove is connected to by protrusion
Two adjustment units are inside made to be fixed together.
Further, the extension is evenly distributed on the shim body edge.
Further, the thickness of the extension is Zi close to the shim body edge to the remote shim body edge
Place is gradually reduced.
Further, the edge of the extension is irregular curve.
Further, the edge of the extension is zigzag.
Further, the shim body and extension are integrally formed.
The advantageous effects that the utility model is reached：The utility model provides a kind of internal diameter adjustable type gasket, passes through
Adjusting part adjusts the internal diameter of the through hole passed through for bolt, the internal diameter for efficiently solving gasket in the prior art immobilize and only
It can be suitably used for a kind of use of size bolt.
Brief description of the drawings
Fig. 1 the utility model structure diagrams.
Wherein：1 shim body；2 extensions；3 adjustment units；4 telescopic rods；5 positioning components.
Embodiment
With reference to specific embodiment, the invention will be further described.Following embodiments are only used for clearly illustrating
Technical scheme, and be not intended to limit the protection scope of the present invention and limit the scope of the invention.
The utility model patent is further illustrated with reference to the accompanying drawings and examples.
As shown in Figure 1, the utility model provides a kind of internal diameter adjustable type gasket, including shim body 1, extension 2 and interior
Footpath adjustment portion, the extension 2 are fixed in the shim body 1, and the extension 2 and the 1 place water of shim body
Plane is in setting angle；The internal diameter adjustment portion includes adjustment unit 3 and telescopic rod 4, and the quantity of the adjustment unit 3 is at least
2, the both ends of the telescopic rod 4 are respectively welded on the outer wall of the adjustment unit 3 and the inner wall of the shim body 1, and
The telescopic rod 4 is positioned by positioning component, the positioning component 5 include being arranged on elastic button on telescopic rod 4 and
Location hole, after the telescopic rod 4 elongates or shortens, is connected in the location hole by elastic button and is fixed on the positioning；Institute
There is adjustment unit 3 is end to end to surround a through hole passed through for bolt.
The side wall of two neighboring adjustment unit 3 is equipped with connection component, is not drawn into figure, and the connection component includes setting
Circular groove and the protrusion being arranged on another adjustment unit side wall on one adjustment unit side wall, are connected to by protrusion
Two adjustment units are made to be fixed together in groove.
In order to ensure the compactness between shim body 1 and mechanical face, the extension is evenly distributed on the gasket sheet
Body edge.The thickness of the extension 2 is Zi close to 1 edge of shim body to remote 1 edge of shim body
It is gradually reduced.The edge of the extension is irregular curve.The edge of especially described extension 2 is zigzag, sawtooth
Form touch machinery face, can effectively prevent gasket from skidding on mechanical face, especially, the shim body 1 and extension 2 one
It is body formed so that shim body 1 is firmer.
The operation principle of the utility model：When needing larger aperture, telescopic rod is in compressive state, in same circumference
On adjustment unit surround a through hole passed through for bolt；When needing less aperture, telescopic rod is extended to all adjustings
Unit is end to end, is fixed on the positioning with positioning component, and adjustment unit surrounds a through hole passed through for bolt.
The utility model is disclosed with preferred embodiment above, so itself and be not used to limitation the utility model, it is all to take
The technical solution that equivalent substitution or the scheme of equivalent transformation are obtained, all falls within the scope of protection of the utility model.
