Abstract

The invention discloses a piston rod sealing part which comprises a sealing part matrix, an inner ring arranged on the sealing part matrix and a boss arranged on an upper portion of the inner ring. A groove is arranged on an inner side of the inner ring, and a retaining ring is arranged in the groove. The piston rod sealing part is simple in structure and improved in stability, and the inner ring can bear bigger force to adapt to bigger extrusion clearance of a cylinder body.

Description

A kind of piston rod seal component
Technical field
The present invention relates to rubber-plastic sealing spare field, particularly relate to a kind of piston rod seal component.
Background technique
Piston rod seal component of the prior art only is provided with an inner ring and is arranged on boss on the inner ring on its Sealing matrix, therefore, when the cylinder body Gap-Ratios was larger, when the cylinder body relative movement, inner ring was extruded easily, thereby lost the effect of sealing.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of a kind of piston rod seal component of good seal performance.
For achieving the above object, the present invention adopts following technological scheme:
A kind of piston rod seal component comprises the Sealing matrix, and is arranged on the inner ring on the Sealing matrix, and the boss that is arranged on inner ring top, described inner ring, and its inboard is provided with groove, is provided with a back-up ring in the groove.
Described inner ring, its inboard are a stressed in the other direction side.
In technique scheme because inner ring of the present invention, its in the other direction a stressed side be provided with groove, be provided with a back-up ring in the groove, inner ring can bear larger power like this so that the adaptation cylinder body larger extrude the gap.
Beneficial effect of the present invention is: simple in structure, increased stability, inner ring can bear larger power so that adapt to cylinder body larger extrude the gap.
Description of drawings
Fig. 1 is structural representation of the present invention.
Among the figure, 1 is the Sealing matrix, and 2 is inner ring, and 21 is back-up ring, and 3 is concave station.
Embodiment
Below by specific embodiment, the present invention is done detailed description.
Referring to Fig. 1, a kind of piston rod seal component, comprise Sealing matrix 1, and be arranged on inner ring 2 on the Sealing matrix 1, and the boss 3 that is arranged on inner ring 2 tops, described inner ring 2, its inboard is provided with groove, be provided with a back-up ring 21 in the groove, described inner ring 2, its inboard is a stressed in the other direction side.

Claims (2)

1. a piston rod seal component comprises the Sealing matrix, and is arranged on the inner ring on the Sealing matrix, and the boss that is arranged on inner ring top, it is characterized in that: described inner ring, its inboard is provided with groove, is provided with a back-up ring in the groove.
2. a kind of piston rod seal component according to claim 1 is characterized in that: described inner ring, its inboard are a stressed in the other direction side.
