Description
Technical field
The utility model belongs to sealing ring production field, and in particular to a kind of reciprocating movement sealing circle.
Background technique
Reciprocating movement sealing circle is generally used for the hydraulic part (such as piston head, cylinder body a part) of various machinery, when work
It generates and reciprocatingly slides between sealing lip and metal surface joined together.Reciprocating movement sealing circle generally comprises sealing ring body and close
Lip is sealed, but such reciprocating movement sealing circle, sealing effect are bad.
In view of the above deficiencies, a kind of reciprocating movement sealing circle is now needed, there is good sealing effect.
Utility model content
The purpose of the utility model is to provide a kind of reciprocating movement sealing circles, have good sealing effect.
The utility model provides the following technical solution:
A kind of reciprocating movement sealing circle, including sealing ring body enclose downside in the sealing ring body and are equipped with sealing lip, institute
The first limiting slot for being equipped with annular between sealing lip and the sealing ring body edge is stated, is equipped with sealing in first limiting slot
Ring, the lower end surface of the sealing ring are equipped with the second limiting slot of annular, are equipped with spring ring in second limiting slot.
Preferably, the upper and lower end face of the sealing ring is equipped with the second limiting slot.
Preferably, second limiting slot cross section is arc.
Preferably, the spring ring includes outer spring, and inner spring is equipped in the outer spring, and the both ends of the inner spring are equal
Equipped with hook, the both ends of the inner spring are end to end by the hook, and the both ends of the outer spring is made to connect.
Preferably, the outer spring and the inner spring are all made of high-carbon steel, and high-carbon steel has high intensity and hardness, height
Elastic limit.
The utility model has the beneficial effects that
(1) bond strength of sealing lip and metal surface, Jin Erti can be improved by sealing ring, spring ring for the utility model
The leakproofness of highly dense seal；
(2) stiffness of spring ring can be improved by outer spring and inner spring for the utility model, can further improve sealing ring
Fastness in conjunction with axis is conducive to improve sealing performance.
Detailed description of the invention
Attached drawing is used to provide a further understanding of the present invention, and constitutes part of specification, practical with this
Novel embodiment is used to explain the utility model together, does not constitute limitations of the present invention.In the accompanying drawings:
Fig. 1 is the utility model main view；
Fig. 2 is coil structures figure.
In the figure, it is marked as 1, sealing ring body；2, sealing lip；3, sealing ring；4, spring ring；41, outer spring；42, interior bullet
Spring；43, hook；5, the first limiting slot；6, the second limiting slot.
Specific embodiment
As shown in Figure 1 to Figure 2, a kind of reciprocating movement sealing circle, including sealing ring body 1 enclose in the sealing ring body 1
Downside is equipped with sealing lip 2, and the first limiting slot 5 of annular, institute are equipped between 1 edge of the sealing lip 2 and the sealing ring body
It states and is equipped with sealing ring 3 in the first limiting slot 5, the lower end surface of the sealing ring 3 is equipped with the second limiting slot 6 of annular, and described second
Spring ring 4 is equipped in limiting slot 6.The bond strength that sealing lip 2 Yu metal surface can be improved by sealing ring 3, spring ring 4, into
And improve the leakproofness of sealing ring body；Sealing ring 3 and spring ring position can be improved by the first limiting slot 5, the second limiting slot 6
It is firm；The upper and lower end face of the sealing ring 3 is equipped with the second limiting slot 6, so can further improve sealing lip 2 and metal watch
The bond strength in face is conducive to improve sealing performance；
Wherein, 6 cross section of the second limiting slot is arc, improves the compatible degree of the second limiting slot 6 and spring ring 4, really
Protect the firm of spring 4；Spring ring 4 includes outer spring 41, is equipped with inner spring 42 in outer spring 41, the both ends of inner spring 42 are equipped with
The both ends of hook 43, inner spring 42 are end to end by hook 43, and the both ends of outer spring 41 is made to connect；Pass through 41 He of outer spring
The stiffness of spring ring 4 can be improved in inner spring 42, can further improve fastness of the sealing ring in conjunction with axis, is conducive to improve leakproofness
Energy；And connects by hook 43 by the both ends of inner spring 42 and outer spring 41 can be surrounded spring ring 4；Outer spring 41 and inner spring
42 are all made of high-carbon steel, and high-carbon steel has high intensity and hardness, high elastic limit.
The working method of the utility model:
As shown in Figure 1 to Figure 2, the bond strength of sealing lip 2 Yu metal surface can be improved by sealing ring 3, spring ring 4,
And then improve the leakproofness of sealing ring body；Sealing ring 3 and spring ring position can be improved by the first limiting slot 5, the second limiting slot 6
That sets is firm.
The above is only the preferred embodiments of the utility model, are not intended to limit the utility model, although referring to before
Embodiment is stated the utility model is described in detail, it for those skilled in the art, still can be to preceding
Technical solution documented by each embodiment is stated to modify or equivalent replacement of some of the technical features.It is all this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
