Abstract
The utility model discloses a kind of sealing rings, including rubber seal ring main body, rubber seal ring main body is axially extending to be equipped with interior sealing lip and outer seal lip, outer seal lip extends to the direction far from sealing circle center, interior sealing lip extends to close to the direction of sealing circle center, forms V-type groove between the interior sealing lip and outer seal lip；Polytetrafluoroethylene gasket is embedded on the inside of the rubber seal ring main body.Sealing ring provided by the utility model is asymmetrically equipped with outer seal lip and interior sealing lip, has good sealing, anti-dust performance；Polytetrafluoroethylene gasket has high temperature resistant, wear-resisting property, can avoid protecting bad problem because ring wear causes, while can extend the service life of sealing ring.
Description
Technical field
The utility model relates to a kind of sealing rings, belong to seal fitting technical field.
Background technique
Sealing ring is critically important for reciprocating dynamic seal device, such as button, knob and key turn round switch piece, in order to reach
To the degree of protection of setting, generallys use V-shaped seal ring and cooperate with the device housings for installing the switch piece.With switch piece
It uses, constantly rubs between sealing ring and switch piece, lead to ring wear, and then cause the problems such as protection is bad.
Utility model content
Purpose: in order to overcome the deficiencies in the prior art, the utility model provides a kind of sealing ring.
Technical solution: in order to solve the above technical problems, the technical solution adopted by the utility model is:
A kind of sealing ring, including rubber seal ring main body, rubber seal ring main body are axially extending equipped with interior sealing lip and outer
Sealing lip, outer seal lip extend to the direction for deviateing sealing circle center, and interior sealing lip extends to close to the direction of sealing circle center,
V-type groove is formed between the interior sealing lip and outer seal lip；Polytetrafluoroethylene (PTFE) pad is embedded on the inside of the rubber seal ring main body
Circle.
Further, the axial height of the interior sealing lip is less than the axial height of outer seal lip.
Further, the annular diameters of the polytetrafluoroethylene gasket are less than the annular diameters of rubber seal ring main body, together
When greater than interior sealing lip annular diameters.
Further, the outer annular diameter of the outer seal lip is greater than the outer annular diameter of rubber seal ring main body.
Further, the V-type groove bottom is with arc transition.
Further, the rubber seal ring main body outer ring sets rear chamfering.
Further, outer seal lip outer ring end sets preceding chamfering.
The utility model has the advantages that sealing ring provided by the utility model, is asymmetrically equipped with outer seal lip and interior sealing lip, it is inside and outside equal
Dynamic sealing can be formed, has good sealing, anti-dust performance；Polytetrafluoroethylene gasket is embedded on the inside of rubber seal ring main body,
Shaft or button etc. of the connection of sealing ring inner ring in use, constantly with sealing ring friction；Due in polytetrafluoroethylene gasket
Ring diameter is smaller than the annular diameters of rubber seal ring main body, and rubber seal ring main body does not contact substantially with sealing medium, and poly- four
Vinyl fluoride has good high temperature resistant, wear-resisting property, can avoid causing the bad problem of protecting because of ring wear, while can be with
Extend the service life of sealing ring.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is further described with reference to the accompanying drawing.
As shown in Figure 1, a kind of sealing ring, including rubber seal ring main body 1, rubber seal ring main body 1 is axially extending to be equipped with
Interior sealing lip 2 and outer seal lip 3, outer seal lip 3 extend to the direction for deviateing sealing circle center, and interior sealing lip 2 is to close to sealing
The direction of circle center extends；The axial height of the interior sealing lip 2 is less than the axial height of outer seal lip 3.Outside outer seal lip 3
Ring diameter is greater than the outer annular diameter of rubber seal ring main body 1.
1 outer ring of rubber seal ring main body sets rear chamfering 11, and 3 outer ring end of outer seal lip sets preceding chamfering 31, and setting is fallen
Angle facilitates the assembly of sealing ring, improves the assembling accuracy of sealing ring.
V-type groove 4 is formed between the interior sealing lip 2 and outer seal lip 3,4 bottom of V-type groove is with arc transition.
Polytetrafluoroethylene gasket 5 is embedded on the inside of the rubber seal ring main body 1；The annular diameters of polytetrafluoroethylene gasket 5
Less than the annular diameters of rubber seal ring main body 1, the annular diameters of simultaneously greater than interior sealing lip 2.During repeating turn, gather
Tetrafluoroethene washer first contacts sealing medium than rubber seal ring main body, and rubs, and polytetrafluoroethylene (PTFE) is with good
High temperature resistant, wear-resisting property can avoid protecting bad problem because ring wear causes, while can extend the use of sealing ring
Service life.
The above is only the preferred embodiment of the utility model, it should be pointed out that: for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the protection scope of the utility model.
