Abstract
The invention discloses a kind of sealing structure, including body and sealing ring, the body is multi-diameter shaft, the body includes Part I and Part II, also include a swivel nut, the swivel nut is threadedly attached on the Part II, the external diameter of the swivel nut is identical with the external diameter of the Part I, the sealing ring is arranged on the position between the swivel nut and the Part I on the body, the sealing ring includes the main body that one section of cross section is cambered surface and the connecting plate for being arranged on main body both ends, the connecting plate inserts the end face of the swivel nut and the end face of the Part I respectively.In use, by the position of Adjusting bolt Adjusting screw, can be with the distance between Adjusting bolt Adjusting screw and Part I, this distance is nearer, and the main body of sealing ring is protruded more outward, that is, the external diameter of sealing ring is bigger, by this regulative mode, sealing ring can be caused to be in close contact with casing wall, avoid leaking.
Description
Technical field
The present invention relates to a kind of hydraulic pump, more particularly to a kind of sealing structure for hydraulic pump.
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 one kind to be used for sealing structure, and it can adjust sealing
The external diameter size of circle, it is easy to sealing ring to be in close contact with casing wall.
The present invention is achieved through the following technical solutions：A kind of sealing structure, including body and sealing ring, the body
For multi-diameter shaft, the body includes Part I and Part II, in addition to a swivel nut, the swivel nut are threadedly attached in
On the Part II, the external diameter of the swivel nut is identical with the external diameter of the Part I, and the sealing ring is arranged on described
Position on body between the swivel nut and the Part I, the sealing ring include the main body that one section of cross section is cambered surface
With the connecting plate for being arranged on main body both ends, the connecting plate inserts the end face of the swivel nut and the end of the Part I respectively
Face.In use, by the position of Adjusting bolt Adjusting screw, can be with the distance between Adjusting bolt Adjusting screw and Part I, this distance is nearer, close
The main body of seal is protruded more outward, that is, the external diameter of sealing ring is bigger, by this regulative mode, can cause sealing ring
It is in close contact with casing wall, avoids leaking.
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 the position of Adjusting bolt Adjusting screw, can be with Adjusting bolt Adjusting screw and first
The distance between point, this distance is nearer, and the main body of sealing ring is protruded more outward, that is, the external diameter of sealing ring is bigger, leads to
This regulative mode is crossed, sealing ring can be caused to be in close contact with casing wall, avoid leaking.
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 and Fig. 2, a kind of sealing structure, including body 1 and sealing ring 2, the sealing ring 2 are made up of steel.
The body 1 is multi-diameter shaft, and the body 1 includes Part I 11 and Part II 12, in addition to a swivel nut
3, the swivel nut 3 is threadedly attached on the Part II 12, and the external diameter of the swivel nut 3 is outer with the Part I 11
Footpath is identical, and the sealing ring 2 is arranged on the position between the swivel nut 3 and the Part I 11, institute on the body 1
Stating sealing ring 2 includes main body 21 and the connecting plate 22 that is arranged on main body 21 both ends, the connecting plate of one section of cross section for cambered surface
22 insert the end face of the swivel nut 3 and the end face of the Part I 11 respectively.
In use, by the position of Adjusting bolt Adjusting screw, can be got over the distance between Adjusting bolt Adjusting screw and Part I, this distance
Closely, the main body of sealing ring is protruded more outward, that is, the external diameter of sealing ring is bigger, by this regulative mode, can cause
Sealing ring is in close contact with casing wall, avoids leaking.
Claims (2)
1. a kind of sealing structure, including body and sealing ring, it is characterised in that：The body is multi-diameter shaft, and the body includes
Part I and Part II, in addition to a swivel nut, the swivel nut are threadedly attached on the Part II, the spiral shell
The external diameter of set is identical with the external diameter of the Part I, and the sealing ring is arranged on the body positioned at the swivel nut and described
Position between Part I, the sealing ring include the main body that one section of cross section is cambered surface, are arranged on the connection at main body both ends
