Abstract
The utility model relates to a pneumatic cylinder technical field specifically discloses a pneumatic cylinder piston packaging protection architecture for nonoculture, including the cylinder, with the cylinder support piece that the cylinder is connected, be equipped with piston, and hinge joint's piston rod in the cylinder, the cover is equipped with the sealing washer on the piston, is fixed with two support rings on the piston the support ring is opened had oily breach, and the breach is located one side of support ring and cylinder inner wall contact surface. The support ring is the soft wear -resistant material of polytetrafluoroethylene. The utility model has the advantages that, fluid strikeed through inflow sealing member, the high pressure that receives that has reduced the sealing member from the support ring breach when fluid pressure was great, and polytetrafluoroethylene support ring itself is wear -resisting simultaneously, even piston reciprocating motion can not cause too big wearing and tearing to it yet, two -sided support ring still keeps off impurity such as iron rust, particulate matters in piston one end, avoids impurity to follow piston back and forth movement and harms the casing wall, effectively increases the life of pneumatic cylinder.
Description
Technical field
This utility model relates to hydraulic cylinder technical field, particularly relates to a kind of single-action hydraulic cylinder piston seal and protects
Protection structure.
Background technology
Cylinder barrel in single-action hydraulic cylinder is generally irony, especially coastal area, and cylinder barrel easily gets rusty, will
Having rust to drop, rust can enter cylinder barrel can damage sealing member, moves as well as piston, enter in cylinder barrel
And causing the frictionally damage of cylinder barrel wall, hydraulic cylinder is short for service life.
Utility model content
The purpose of this utility model is to provide a kind of single-action hydraulic cylinder piston seal protection structure, polytetrafluoroethyl-ne
Alkene support ring is wear-resisting, can effectively protect the damage of sealing member by gears such as rust in piston one end, extended
Service life of hydraulic cylinder.
To achieve these goals, this utility model have employed following technical scheme: a kind of single-acting hydraulic
Cylinder piston seal protection structure, the cylinder barrel support member being connected with cylinder barrel including cylinder barrel, it is provided with in described cylinder barrel
The piston rod that piston is connected with piston；It is arranged with sealing ring on described piston, described piston is fixed with two
Individual support ring.
Wherein, had the breach of oil in described support ring, and breach was positioned at support ring and contacts with inner wall of cylinder
The side in face.
Wherein, described support ring is the soft high-abrasive material of politef.
The beneficial effects of the utility model are: when fluid pressure is bigger, fluid passes through to flow into from support ring breach
Sealing member, decrease sealing member by impacting with high pressure, politef support ring itself is wear-resisting simultaneously, even if
It also will not be caused the biggest abrasion by reciprocating motion of the pistons, and double side support ring is also miscellaneous by rust, particulate matter etc.
Matter is kept off in piston one end, it is to avoid impurity moves back and forth damage casing wall with piston, is effectively increased the use of hydraulic cylinder
Life-span.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment technical scheme, institute in embodiment being described below
The accompanying drawing used is needed to be briefly described, it should be apparent that, the accompanying drawing in describing below is only this practicality
Novel in order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below by p-
In embodiment or description of the prior art, the required accompanying drawing used is briefly described, skill common for this area
From the point of view of art personnel, on the premise of not paying creative work, it is also possible to obtain other according to these accompanying drawings
Embodiment.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, to the technical side in this utility model embodiment
Case is clearly and completely described, it is clear that described embodiment is only that this utility model part is real
Execute example rather than whole embodiments.Based on the embodiment in this utility model, ordinary skill people
The every other embodiment that member is obtained under not making creative work premise, broadly falls into this utility model
The scope of protection.
A kind of single-action hydraulic cylinder piston seal protection structure as shown in Figure 1, including cylinder barrel 4 and cylinder barrel 4
The cylinder barrel support member 1 connected, is provided with the piston rod 3 that piston 2 is connected with piston 2 in described cylinder barrel 4；Institute
State and on piston 2, be arranged with sealing ring 5, described piston 2 is fixed with two support rings 6.
Had the breach of oil in described support ring 6, and breach was positioned at support ring 6 and cylinder barrel 4 contact internal walls
The side in face, when fluid pressure is bigger, fluid is from support ring breach by flowing into sealing member, decreases sealing member
By impacting with high pressure.
More optimizedly, described support ring 6 is the soft high-abrasive material of politef.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model,
All within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, all
Within protection domain of the present utility model should be included in.
