Abstract
The utility model discloses a cylinder piston seal with a buffering function. The cylinder piston seal comprises a piston sealing member and a guide ring which supports and guides a piston. The guide ring is disposed in a center hole of the piston sealing member. The piston sealing member comprises a sealing lip structure having an angle r and a buffering structure having an air passage. The cylinder piston seal with the buffering function is in the integrated design, one element has the buffering function and the sealing function, fewer parts are used, and mounting space is maximally reduced.
Description
Technical field
The utility model relates to cylinder seal technical field, particularly a kind of cylinder piston sealing with buffering.
Background technique
In general cylinder seal, piston seal only plays single seal action, and in today of science and technology fast development, cylinder is gradually to microminiaturization, integrated, improves reliability and the development that increases the service life of element.
For general cylinder seal scheme, piston element plays guide support effect except installation piston seal also needs to install pilot seal, and this just needs different grooves, the more installing space of demand.For also needing to consider cushion seal in the king-sized cylinder seal of pressure.And there is following shortcoming in the existing cylinder piston sealing that meets the demand:
1, structure is numerous and diverse, and installing space is large;
2, can only play single seal action.
Model utility content
The purpose of this utility model is the problem in order to solve above-mentioned existence, and a kind of cylinder piston sealing with buffering is provided.
The technical solution of the utility model is as follows:
A kind of cylinder piston sealing with buffering, comprise piston seal and piston is played to the guide ring of support guide effect, described guide ring is arranged in the center hole of described piston seal, and wherein said piston seal comprises containing the structure of sealing lip at r angle and establishes duct-ventilated buffer structure.
Preferably, the described structure of sealing lip containing r angle is arranged on the bottom of described piston seal, described in establish duct-ventilated buffer structure and be arranged on described piston seal top.
Compared with prior art, the beneficial effects of the utility model are as follows:
The cylinder piston sealing of band of the present utility model buffering adopts integral type design, and on an element, integrated buffering, seals two kinds of functions, has reduced amount of parts, has dwindled to the full extent installing space.
Brief description of the drawings
Fig. 1 is the use status architecture schematic diagram of the cylinder piston sealing of the utility model embodiment's band buffering;
Fig. 2 is the cross-sectional view of the piston seal of the cylinder piston sealing of the utility model embodiment's band buffering;
Fig. 3 is the cross-sectional view of the guide ring of the cylinder piston sealing of the utility model embodiment's band buffering.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described.Following examples, only for illustrating, limit protection domain of the present utility model and be not used in.
Embodiment
Refer to Fig. 1-Fig. 3, a kind of cylinder piston sealing with buffering that the present embodiment provides, comprise piston seal 1 and piston is played to the guide ring 2 of support guide effect, wherein guide ring 2 is arranged in the center hole of piston seal 1, and wherein piston seal 1 comprises containing the structure of sealing lip 3 at r angle and establishes duct-ventilated buffer structure 4.
Wherein, be arranged on the bottom of piston seal 1 containing the structure of sealing lip 3 at r angle, establish duct-ventilated buffer structure 4 and be arranged on the top of piston seal 1.
The cylinder piston sealing of the band buffering of the present embodiment adopts integral type design, and on an element, integrated buffering, seals two kinds of functions, has reduced amount of parts, has dwindled to the full extent installing space.
Disclosed is above only the utility model preferred embodiment.Preferred embodiment does not have all details of detailed descriptionthe, and also not limiting this model utility is only described embodiment.Obviously,, according to the content of this specification, can make many modifications and variations.These embodiments are chosen and specifically described to this specification, is in order to explain better principle of the present utility model and practical application, thereby make one of ordinary skill in the art can utilize well the utility model.The utility model is only subject to the restriction of claims and four corner and equivalent.
Claims (2)
1. the cylinder piston sealing with buffering, it is characterized in that, comprise piston seal and piston is played to the guide ring of support guide effect, described guide ring is arranged in the center hole of described piston seal, and wherein said piston seal comprises containing the structure of sealing lip at r angle and establishes duct-ventilated buffer structure.
2. the cylinder piston sealing of band according to claim 1 buffering, is characterized in that, the described structure of sealing lip containing r angle is arranged on the bottom of described piston seal, described in establish duct-ventilated buffer structure and be arranged on described piston seal top.
