Abstract
The utility model discloses a kind of for being adapted to the piston body structure of sealing ring, including piston only and pedestal, and piston only bottom is equipped with one for the groove of sealing ring installation, and base abutment is removably attached on piston only in the bottom surface of groove.After adopting the above scheme, sealing ring can be installed on groove before pedestal is fixed to piston only, without professional tool when installation, while being avoided sealing ring additional stretch during installation and being easy the problem of scratching by surface when slot wedge.
Description
Technical field
The utility model relates to the mounting technology fields of sealing ring, refer in particular to a kind of for being adapted to the piston body of sealing ring
Structure.
Background technique
Existing piston body structure needs to be stretched to sealing ring more than piston body diameter during installation, slips over groove
Edge enters back into groove.During the installation process, specific purpose tool need to be used, sealing ring need to be elongated additionally, and pass through ditch trough rim
Surface is easy to scratch when edge.
In view of this, the utility model, which is developed, overcomes a kind of for being adapted to the piston body knot of sealing ring of the defect
Thus structure, this case generate.
Summary of the invention
It is existing to solve the main purpose of the utility model is to provide a kind of piston body structure for being easily installed sealing ring
Sealing ring, which needs additionally to elongate during installation, is easy the problem of scratching with by surface when slot wedge.
In order to achieve the above objectives, the solution of the utility model are as follows:
It is a kind of for being adapted to the piston body structure of sealing ring, including piston only and pedestal, piston only bottom is equipped with one
For the groove of sealing ring installation, base abutment is removably attached on piston only in the bottom surface of groove.
After adopting the above scheme, the installation steps of the utility model are as follows: firstly, sealing ring is mounted on the ditch of piston only
Slot；Then, base abutment is removably attached on piston only in the bottom surface of groove, and sealing ring is made to be fixed on piston only
On.While guaranteeing sealing effect, without specific purpose tool installation, the additional stretch of sealing ring during installation is avoided,
A possibility that reducing the sealing ring risk that surface is scratched during installation, reducing seal leakage, while extending sealing ring
Service life.
Further, the groove of piston only is L-type.
Using above-mentioned design, piston body, which is changed to L-type groove by original U-shaped groove, makes piston body disclosed by the utility model
It is easy to process while improving intensity.
Further, it is equipped with a sealing plate between piston only and pedestal, is used for sealing piston ontology and pedestal.
Further, pedestal is connect by bolt with sealing plate, piston only.
Further, piston only and pedestal are rigid metal material.
Further, sealing plate uses flexible metal or nonmetallic materials, and copper sheet, rubber, silica gel, polyurethane rubber can be used
Glue, polytetrafluoroethylene (PTFE), asbestos rubber, cork sheet or felt.
Further, sealing ring is common sealing ring, and shape is that O-ring seal, y-type seal ring, V-shaped seal ring, L-type are close
Seal or J-type sealing ring.
Detailed description of the invention
Fig. 1 is the schematic perspective view of the utility model；
Fig. 2 is the cross-sectional view of Fig. 1.
Label declaration
1 pedestal 2 of piston only
3 bolt 4 of sealing plate
11 trench bottom surfaces 12 of groove.
Specific embodiment
The utility model is described in detail below in conjunction with drawings and the specific embodiments.
As depicted in figs. 1 and 2, the utility model discloses a kind of for being adapted to the piston body structure of sealing ring, including work
The bottom of plug body 1 and pedestal 2, piston only 1 is equipped with a groove 11, and sealing ring is mounted on groove 11, and pedestal 2 is resisted against ditch
The bottom surface 12 of slot 11, is removably attached on piston only 1.Since piston only 1 and pedestal 2 are rigid metal material,
Between the two connection if sealing plate 3 is not added and seals, it is possible to have liquid and be leaked out from junction.Preferably, in work
Between plug body 1 and pedestal 2 be equipped with a sealing plate 3, be used for sealing piston ontology 1 and pedestal 2, pedestal 2 by bolt 4 with it is close
Sealing plate 3, piston only 1 connect.To make piston only 1 and the leakproofness of pedestal 2 preferable, sealing plate 3 using flexible metal or
Copper sheet, rubber, silica gel, polyurethane rubber, polytetrafluoroethylene (PTFE), asbestos rubber, cork sheet or felt can be used in nonmetallic materials.
To improve the intensity of piston body 1 and convenient for the processing of piston body 1, groove is by original U-type groove on piston only 1
It is changed to L-type slot.
In this way, sealing ring can be installed on groove 11 before sealing plate 3 and pedestal 2 are fixed to piston only 1, pacify
Without professional tool when dress, while avoiding sealing ring additional stretch during installation and by surface when slot wedge
A possibility that being easy the problem of scratching, reducing seal leakage, extends the service life of sealing ring.
The sealing ring (not shown) is common sealing ring, and shape is O-ring seal, y-type seal ring, V-seal
Circle, L-type sealing ring or J-type sealing ring.
The above is only the preferred embodiment of the present invention, not to the limitation of this case design, all setting according to this case
The crucial equivalent variations done of meter, each falls within the protection scope of this case.
