Description
Technical field
The utility model relates to oil seal technique fields, more particularly to a kind of multi-sealed oil sealing.
Background technique
Disclose the patent of oil sealing in existing Chinese patent database, number of patent application 201710444969.1,
The applying date is 2017.06.12, application publication number CN 109027240 A, data of publication of application 2018.12.18, which is arranged
In shaft member, comprising: annular sealing member, be included in the annular sealing member diametrically opposite and connected inner seal ring and outer branch
Carrier ring, the inner seal ring are included in the contact portion in the axial direction of the inner seal ring being distributed and be connected with each other in succession and heat dissipation
Portion；Heat dissipation element is set to the radiating part；Wherein, the contact portion can contact sealing with the peripheral surface of the shaft member,
The radiating part and the heat dissipation element can be by the heat transfers of the inner seal ring to external environment, to described interior close
Seal ring radiates.Disadvantage is that: the oil sealing is suitable in shaft member, the connection not being suitable between Guan Yuguan, and close
Seal less effective.
Utility model content
The purpose of this utility model be in view of the deficienciess of the prior art, provide it is a kind of be suitable for Guan Yuguan connection, it is more
The oil sealing of resealing.
To achieve the goals above, a kind of technical solution that multi-sealed oil sealing is taken of the utility model:
A kind of multi-sealed oil sealing, including rabbeting the annular rubber gasket in peripheral hardware device aperture, the ring-shaped rubber
Washer one end is equipped with the cone shaped elastic rubber cover being coaxially disposed with annular rubber gasket, the osculum end of cone shaped elastic rubber cover and ring
Shape rubber washer is affixed, and the big opening end of cone shaped elastic rubber cover is free end and extends on the outside of annular rubber gasket lateral surface,
The big opening end edge of cone shaped elastic rubber cover contradicts on the inner wall in peripheral hardware device aperture.
When utility model works, annular rubber gasket is rabbeted in the hole of peripheral device, keeps cone shaped elastic rubber cover big
Mouth end margin conflict is screwed in the hole of peripheral device on the hole wall of peripheral device, then by peripheral hardware connecting tube, connects peripheral hardware
Pipe end contradicts on annular rubber gasket, and by cone shaped elastic rubber cover compressive deformation, sealing ring rubber washer and peripheral hardware are filled
Set the gap between hole.
Compared with prior art, the utility model has the following beneficial effects: due to cone shaped elastic rubber cover presence, Conical Projectile
Property rubber cover free end edge contradict on hole wall, gap between effective sealing hole and annular rubber gasket, while peripheral hardware
Pipe end extrusion ring shape rubber washer is connected, makes cone shaped elastic rubber cover compressive deformation, reliably and effectively sealing ring rubber pad
Gap between circle and hole wall.
The annular rubber gasket other end is equipped with the elastic rubber pipe coaxial with annular rubber gasket, in elastic rubber pipe
Wall connect pipe outer wall fitting with peripheral hardware, and elastic rubber pipe outer wall is bonded with peripheral device hole wall.It is socketed in peripheral hardware connecting tube
Elastic rubber pipe effectively limits annular rubber gasket, avoids annular rubber gasket deformation, and influences leakproofness.
The annular groove coaxial with annular rubber gasket is offered on the elastic rubber pipe, annular groove is embedded to be connected to outside
Convex sealing ring, the sealing ring contradict on peripheral hardware device aperture wall.Sealing ring effectively blocks elastic rubber pipe and peripheral hardware fills
The gap between the inner wall of hole set.
The annular groove cell wall forms annular convex shoulder and is socketed in peripheral hardware connecting tube to elastic rubber pipe convex.Peripheral hardware
Connecting tube contradicts on annular convex shoulder, and the sealing central shoring in annular groove is big, contradicts on the hole inner wall of peripheral device.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Wherein, 1 annular rubber gasket, 2 cone shaped elastic rubber covers, 3 elastic rubber pipes, 301 annular grooves, 302 convex annulars
Shoulder, 4 sealing rings.
Specific embodiment
It as described in Figure 1, is a kind of multi-sealed oil sealing, including rabbeting the annular rubber gasket 1 in peripheral hardware device aperture,
1 one end of annular rubber gasket is equipped with the cone shaped elastic rubber cover 2 being coaxially disposed with annular rubber gasket 1, cone shaped elastic rubber cover 2
Osculum end and annular rubber gasket 1 it is affixed, the big opening end of cone shaped elastic rubber cover 2 is free end and extends to ring-shaped rubber pad
It encloses on the outside of 1 lateral surface, the big opening end edge of cone shaped elastic rubber cover 2 contradicts the ring-shaped rubber on the inner wall in peripheral hardware device aperture
1 other end of washer is equipped with the elastic rubber pipe 3 being coaxially disposed with annular rubber gasket 1, and 3 inner wall of elastic rubber pipe is connect with peripheral hardware
Pipe outer wall fitting, 3 outer wall of elastic rubber pipe are bonded with peripheral device hole wall.The elastic rubber pipe 3 being socketed in peripheral hardware connecting tube
Annular rubber gasket 1 is effectively limited, 1 deformation of annular rubber gasket is avoided, and influences leakproofness, is opened up on elastic rubber pipe 3
There are the annular groove 301 being coaxially disposed with annular rubber gasket 1, the embedded sealing ring 4 for being connected to evagination of annular groove 301, sealing
Ring 4 contradicts on peripheral hardware device aperture wall.Sealing ring 4 effectively blocks between elastic rubber pipe 3 and the hole inner wall of peripheral device
Gap, 301 cell wall of annular groove form annular convex shoulder 302 and are socketed in peripheral hardware connecting tube to 3 convex of elastic rubber pipe.Peripheral hardware
Connecting tube contradicts on annular convex shoulder 302, and the sealing ring 4 in annular groove 301 is supportted greatly, the hole inner wall in peripheral device is contradicted
On.
When work, annular rubber gasket 1 is rabbeted in the hole of peripheral device, makes 2 big opening end edge of cone shaped elastic rubber cover
It contradicts on the hole wall of peripheral device, is screwed in the conflict of sealing ring 4 on the hole inner wall of peripheral device, then by peripheral hardware connecting tube
In the hole of peripheral device, contradict peripheral hardware connection pipe end on annular rubber gasket, by 2 compressed shape of cone shaped elastic rubber cover
