Abstract
The utility model relates to a kind of ready-package eccentric abrasion prevention piston I II, including piston core, piston rubber, piston rubber is installed on piston core, it is characterised in that: the upper end of piston core is provided with several lower grooves, the protrusion to complement one another with lower groove is provided in the lower end of piston rubber.The utility model has the following beneficial effects: piston core is combined using groove and protrusion with piston rubber, piston rubber and piston core vulcanization are integral, increase the stability of piston rubber.
Description
Technical field
The utility model relates to a kind of ready-package eccentric abrasion prevention piston I II.
Background technique
Outer circle at the piston structure of the prior art and cylinder sleeve cooperation, there are right angle annulars at end face right angle chamfering, outer circle two
The use of grooving designs, the defect of this design structure, first is that, end face right angle chamfering cause with generated at outer circle burr, squeeze bits,
Phenomena such as colliding with；Second is that outer circle annular groove is easy to retain silt, the phenomenon that causing piston to scratch cylinder sleeve, the use of cylinder sleeve is reduced
Service life, while seriously affecting the service life of rubber.
The utility model provides a kind of plug rubber while still alive and piston core vulcanization is integral, increases the fast of piston rubber stability
Dress formula eccentric abrasion prevention piston I II.
Utility model content
The utility model provides a kind of plug rubber and piston core while still alive and is sulfided into one to make up the defect of the prior art
Body increases the ready-package eccentric abrasion prevention piston I II of piston rubber stability.
To achieve the goals above, the utility model provides the following technical solution:
Ready-package eccentric abrasion prevention piston I II, including piston core, piston rubber, are equipped with piston rubber on piston core, special
Sign is: the upper end of piston core being provided with several lower grooves, is provided in the lower end of piston rubber and complements one another with lower groove
Protrusion.
Further, the protrusion of the piston rubber is mounted on inside the groove on piston core, piston rubber and piston core
Vulcanization is integral.
Further, the angle head cylindrical of the piston core is set as rounded structure.
Further, using double angle designs at the lip of the piston rubber.
Further, double angles are mainly made of obtuse angle included angle A and obtuse angle included angle B.
The utility model has the following beneficial effects: piston core is combined using groove and protrusion with piston rubber, piston glue
Skin and piston core vulcanization are integral, increase the stability of piston rubber.
Detailed description of the invention
Fig. 1 is the embodiments of the present invention structural schematic diagram.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the utility model is described in further detail.It should be appreciated that specific embodiment described herein is only to explain this
Utility model is not used to limit the utility model.
Embodiment: according to Fig. 1, the utility model ready-package eccentric abrasion prevention piston I II, including piston core 1, piston rubber
2, piston rubber 2 is installed on piston core 1, it is characterised in that: the upper end of piston core 1 is provided with several grooves 3, in piston
The lower end of rubber 2 is provided with the protrusion 4 to complement one another with groove 3.
The protrusion 4 of the piston rubber 2 is mounted on 3 the inside of groove on piston core 1, and piston rubber 2 and piston core 1 vulcanize
Integrally.
The angle head cylindrical 5 of the piston core 1 is set as rounded structure.
Using double angle designs at the lip of the piston rubber 2.
Double angles are mainly made of obtuse angle included angle A 6 and obtuse angle included angle B 7.
Compared with prior art, the utility model has the advantage that
1, piston core outer circle uses rounded structure, eccentric abrasion prevention；
2, piston core is combined using more grooves and protrusion, and piston core and the vulcanization of piston rubber are integral, increases piston
The stability of rubber；
3, prolonged the service life at the lip of piston rubber using double angle designs.
The utility model has the following beneficial effects: piston core is combined using groove and protrusion with piston rubber, piston glue
Skin and piston core vulcanization are integral, increase the stability of piston rubber.
The utility model is not confined to these for being further described to the utility model by above-described embodiment
Specific embodiment.Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention etc.,
It is interpreted as being within the protection scope of the utility model.Above-described embodiment is only used for illustrating the invention structure of the utility model
Think, rather than the restriction to the utility model rights protection, all non-essential modifications to the present invention made by this concept,
The protection scope of the utility model should all be fallen into.
