Abstract
The utility model provides one kind can be with the sealing ring of storing lubricating grease, it is set on the piston of cylinder, two bottom surfaces of the sealing ring respectively open up an annular groove, the diameter of two annular grooves differs, open up fluted on the lateral wall of the sealing ring, the lubricating grease is stored in the annular groove and/or groove.The advantages of sealing ring are as follows: 1. since it is to open up annular groove on itself, and overall dimensions do not change, and do not influence its leakproofness；2. having grease lubrication since lubricating grease can be stored in groove and/or annular groove in the top, lower section and side of sealing ring, comprehensively being lubricated piston, improve its service life.
Description
Technical field
The utility model relates to cylinder system field of sealing technology, more particularly to one kind can be with the sealing ring of storing lubricating grease.
Background technique
In cylinder system, piston and valve are all important components, between piston and cylinder and the sealing of cylinder itself
Whether sexual intercourse being capable of normal use to cylinder system.In use due to piston, cylinder air flows, so that lubrication
Rouge is easier to volatilize, and adds lubricating grease every time and requires to dismantle, process is relatively complicated, therefore how to be both able to maintain cylinder pressurization ratio
The probability that addition lubricating grease can well be can be reduced again becomes those skilled in the art's urgent problem to be solved.
Utility model content
The utility model provides one kind can be with the sealing ring of storing lubricating grease, for solving the above problems.
In order to achieve the above object, the utility model provides, and one kind can be set in cylinder with the sealing ring of storing lubricating grease
Piston on, two bottom surfaces of the sealing ring respectively open up an annular groove, and the diameter of two annular grooves differs, the outside of the sealing ring
Open up fluted on wall, the lubricating grease is stored in the annular groove and/or groove.
Preferably, the cross sectional shape of two annular grooves is V-type on the section of the sealing ring.
Preferably, the notch of two annular grooves pair it is contrary, and each side wall of an annular groove with it is another
Corresponding side wall is parallel in a annular groove.
Preferably, the section of the groove is also V-type.
Preferably, being all provided with chamfering between the lateral wall of the sealing ring and two bottom surfaces.
Compared with prior art, the utility model has the beneficial effects that the utility model, which provides one kind, can store profit
The sealing ring of consistent lubricant, is set on the piston of cylinder, and two bottom surfaces of the sealing ring respectively open up an annular groove, two annular grooves it is straight
Diameters etc., open up on the lateral wall of the sealing ring fluted, and the lubricating grease is stored in the annular groove and/or groove.It should
The advantages of sealing ring are as follows:
1. overall dimensions do not change since it is to open up annular groove on itself, its leakproofness is not influenced；
2. since lubricating grease can be stored in groove and/or annular groove, in the top, lower section and side of sealing ring
There is grease lubrication, piston is comprehensively lubricated, its service life is improved.
Detailed description of the invention
Fig. 1 be it is provided by the utility model can be with the sealing ring schematic cross-section of storing lubricating grease；
Fig. 2 can use schematic diagram to be provided by the utility model with the sealing ring of storing lubricating grease.
In figure: 100- annular groove, the first annular groove of 110-, the second annular groove of 120-, 200- groove, 300- chamfering, 400- piston.
Specific embodiment
To keep the above objects, features, and advantages of the utility model more obvious and easy to understand, with reference to the accompanying drawing to this
The specific embodiment of utility model is described in detail.
Referring to Fig.1 and 2, the utility model, which provides one kind, to be set in cylinder with the sealing ring of storing lubricating grease
Piston 400 on, two bottom surfaces of the sealing ring respectively open up an annular groove 100, that is to say, that sealing ring itself be an annulus
Column opens up first annular groove 110 on upper bottom surface, opens up second annular groove 120 on bottom surface, the first annular groove 110 it is straight
Diameter is greater than the second annular groove 120, and two 100 positions of annular groove are opposite, that is to say, that the notch of two annular grooves 100 pair direction phase
Instead, cross sectional shape is V-type, and the cell wall of two annular grooves 100 is parallel to each other, i.e. the first annular groove 110 and the second annular groove 120 it
Between distance it is nearest two side walls it is parallel, other two side wall lie farthest away but be also parallel to each other, two annular grooves 100 itself are
Symmetric figure, symmetry axis are perpendicular to entire sealing ring bottom surface.
Fluted 200 are opened up on the lateral wall of the sealing ring, the section of groove 200 is also V-type, the lubricating grease storage
In the first annular groove 110 and/or the second annular groove 120 and/or groove 200.
Preferably, chamfering 300 is all provided between the lateral wall of the sealing ring and two bottom surfaces, so that installation is more
It is convenient.
The utility model provide it is a kind of can be with the sealing ring of storing lubricating grease, the advantages of the sealing ring are as follows:
1. overall dimensions do not change since it is to open up annular groove on itself, its leakproofness is not influenced；
2. since lubricating grease can be stored in groove 200 and/or annular groove 100, the top of sealing ring, lower section with
And there is grease lubrication in side, is comprehensively lubricated piston, improves its service life.
Obviously, it is practical new without departing from this can to carry out various modification and variations to utility model by those skilled in the art
The spirit and scope of type.If these modifications and variations of the present invention belong to the claims of the present invention and its equivalent technology
Within the scope of, then the utility model is also intended to including these modification and variations.
