Abstract
The invention discloses a kind of sealing structure, include the body and sealing ring of cylinder, also include two sleeve pipes, described sleeve pipe connects on the body, the sealing ring is arranged on the position between two described sleeve pipes on the body, the sealing ring includes cross section for the main body of arc and the connecting plate at the main body both ends, the end face of the connecting plate insertion described sleeve pipe.During use, by adjusting the distance between two sleeve pipes, the curvature of main part of sealing ring can be allowed to change, the distance between sleeve pipe is nearer, main body curvature is bigger, the external diameter of namely sealing ring is bigger, and the distance between sleeve pipe is more remote, and main body curvature is smaller, the external diameter of namely sealing ring is smaller, in this way, the external diameter size of sealing ring can be adjusted, is easy to sealing ring to be in close contact with casing wall.
Description
Technical field
The present invention relates to a kind of hydraulic cylinder, more particularly to the sealing mechanism used on hydraulic cylinder.
Background technology
Traditional plunger includes the body of cylinder, and described body sidewall sets groove, sealing ring is set in groove.Tradition
Sealing ring be all a ring shape rubber ring, this sealing ring can not be adjusted, if after loading onto, finding local sealing not
Good, this also has no idea to adjust, it is therefore necessary to is improved.
The content of the invention
For the deficiencies in the prior art, the invention provides a kind of sealing structure, and it can adjust sealing ring
External diameter size, it is easy to sealing ring to be in close contact with casing wall.
The present invention is achieved through the following technical solutions：Sealing structure, include the body and sealing ring of cylinder, also wrap
Two sleeve pipes are included, described sleeve pipe connects on the body, and the sealing ring, which is arranged on the body, is located at two sets
Position between pipe, the sealing ring include cross section for the main body of arc and the connecting plate at the main body both ends, the connection
Plate inserts the end face of described sleeve pipe.In use, by adjusting the distance between two sleeve pipes, the main part of sealing ring can be allowed
Curvature change, the distance between sleeve pipe is nearer, and main body curvature is bigger, that is, the external diameter of sealing ring is bigger, sleeve pipe it
Between distance it is more remote, main body curvature is smaller, that is, the external diameter of sealing ring is smaller, in this way, can adjust sealing ring
External diameter size, be easy to sealing ring and casing wall to be in close contact.
In above-mentioned technical proposal, it is preferred that described sleeve pipe is threadedly attached on the body.
In above-mentioned technical proposal, it is preferred that the sealing ring is made up of steel.
The present invention has the advantages that：In use, by adjusting the distance between two sleeve pipes, sealing ring can be allowed
The curvature of main part change, the distance between sleeve pipe is nearer, and main body curvature is bigger, that is, the external diameter of sealing ring is got over
Greatly, the distance between sleeve pipe is more remote, and main body curvature is smaller, that is, the external diameter of sealing ring is smaller, in this way, can adjust
The external diameter size of sealing ring is saved, is easy to sealing ring to be in close contact with casing wall.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Fig. 2 is Fig. 1 close-up schematic view.
Embodiment
The present invention is described in further detail with embodiment below in conjunction with the accompanying drawings：
Referring to Fig. 1-2, sealing structure includes cylindrical body 1 and sealing ring 2, and the sealing ring 2 is made up of steel.
Also include two sleeve pipes 3, described sleeve pipe 3 is threadedly attached on the body 1, and the sealing ring 2 is arranged on
Position on the body 1 between two described sleeve pipes 3, the sealing ring 2 include the He of main body 21 that cross section is arc
The connecting plate 22 at the both ends of main body 21, the connecting plate 22 insert the end face of described sleeve pipe 3.
In use, by adjusting the distance between two sleeve pipes, the curvature of main part of sealing ring can be allowed to become
To change, the distance between sleeve pipe is nearer, and main body curvature is bigger, that is, the external diameter of sealing ring is bigger, and the distance between sleeve pipe is more remote,
Main body curvature is smaller, that is, the external diameter of sealing ring is smaller, in this way, can adjust the external diameter size of sealing ring, just
It is in close contact in sealing ring and casing wall.
Claims (3)
