Description
Technical field
This utility model relates to technical field of sealing technology, is specifically related to a kind of sealing gland.
Background technology
Sealing gland, is one important in pneumatic auxiliary, and it is roughly divided into movable sealing and static seal two kinds.Owing to movable sealing is used
Rotating, moving back and forth position, its sealing, wearability and service life are all had higher requirements by long-term friction of motion.As
Accompanying drawing 1 is existing to be made up of skeleton A and sealing ring B for reciprocating sealing gland, and sealing ring is inside and outside when in use
Circle extruding forms a sealing surface, and single sealing surface, through long-term motion friction, abrasion easily occurs, causes sealing to reduce, loses
Effect, service life is short, Shortcomings.
Utility model content
For above-mentioned deficiency, this utility model provides a kind of sealing gland, has multi-sealed effective, and wearability is good, from profit
Property is good, service life length feature.
For achieving the above object, the technical solution of the utility model is:
A kind of sealing gland, including skeleton and the sealing ring body that is coated on skeleton；The inner sealing surface of described sealing ring body
On be formed with the upper interior sealing lip of protrusion and lower interior sealing lip, the external seal face of described sealing ring body is formed with
The upper outer seal lip protruded and lower outer seal lip；The indent of arcuation it is provided with between described interior sealing lip and described lower interior sealing lip
Groove, is provided with the external groove of arcuation between described upper outer seal lip and described lower outer seal lip.
Described upper interior sealing lip by described sealing ring body extend first in ramp and first lower inclined plane intersect
Constitute；Described lower interior sealing lip by described sealing ring body extend second in ramp and second lower inclined plane intersect and constitute；
Described inner groovy is intersected by ramp in lower inclined plane and second in first and constitutes.
The first outer ramp and the first outer lower inclined plane that described upper outer seal lip is extended by described sealing ring body intersect
Constitute；The second outer ramp and the second outer lower inclined plane that described lower outer seal lip is extended by described sealing ring body intersect structure
Become；Described external groove has the first outer lower inclined plane and the second outer ramp to intersect composition.
Improve as one, described sealing ring body and described interior sealing lip, lower interior sealing lip, upper outer seal lip, under
The outer surface of outer seal lip is coated with polytetrafluorethylecoatings coatings.
The beneficial effects of the utility model are:
(1) it is equipped with 2 road sealing lips on the inside and outside sealing surface of sealing ring body of the present utility model, forms 2 sealing surfaces,
Multi-sealed effective, and after wherein one sealing lip lost efficacy, also have other one sealing lip work.
(2) this utility model is coated with polytetrafluorethylecoatings coatings, can improve wearability and the self-lubricity of sealing lip, reduces
Coefficient of friction, increases the service life.
(3) interior external groove of the present utility model not only provided extruding wider space for sealing lip but also can store sealing medium, carried
High leakproofness.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing sealing gland；
Fig. 2 is the cross section structure schematic diagram that this is novel.
Detailed description of the invention
Embodiment:
As in figure 2 it is shown, a kind of sealing gland, including skeleton (1) and the sealing ring body (2) that is coated on skeleton；Described sealing
Upper interior sealing lip (21) and lower interior sealing lip (22), the described sealing of protrusion it is formed with on the inner sealing surface of circle body (2)
Upper outer seal lip (23) and the lower outer seal lip (24) of protrusion it is formed with on the external seal face of circle body (2)；Described interior
The inner groovy (25) of arcuation, described upper outer seal lip (23) and institute it is provided with between sealing lip (21) and described lower interior sealing lip (22)
State the external groove (26) being provided with arcuation between lower outer seal lip (24).
Described upper interior sealing lip (21) by described sealing ring body (2) extend first in ramp (211) and first
Interior lower inclined plane (212) intersects composition；Described lower interior sealing lip (22) by described sealing ring body (2) extend second in ramp
(221) in and the second, lower inclined plane (222) intersects composition；Described inner groovy (25) is by lower inclined plane (212) and second in first
Ramp (221) intersects composition.
The first outer ramp (231) and first that described upper outer seal lip (23) is extended by described sealing ring (2) body
Outer lower inclined plane (232) intersects composition；Described lower outer seal lip (24) by described sealing ring body (2) extend second outside upper tiltedly
Face (241) and the second outer lower inclined plane (242) intersect composition；Described external groove (26) has the first outer lower inclined plane (232) and second
Outer ramp (241) intersects composition.
Improve as one, described sealing ring body (2) and described interior sealing lip (21), lower interior sealing lip (22), on
Outer seal lip (23), the outer surface of lower outer seal lip (24) are coated with polytetrafluorethylecoatings coatings (not shown).
The above is preferred implementation of the present utility model, it is noted that for the ordinary skill of the art
For personnel, on the premise of without departing from this utility model principle, it is also possible to make some improvements and modifications, these improve and profit
Decorations are also considered as protection domain of the present utility model.
