Abstract
The utility model discloses a piston rod sealing element, which comprises a sealing element base body, an inner ring arranged on the sealing element base body and a boss arranged on the upper portion of the inner ring. A groove is arranged on the inner side of the inner ring, and a check ring is arranged in the groove. The piston rod sealing element is simple in structure and improves stability, and the inner ring can bear a larger force so as to adapt to a larger extruding gap of a cylinder body.
Description
Technical field
The utility model relates to rubber-plastic sealing spare field, particularly relates to a kind of rod seal part.
Background technique
Rod seal part of the prior art only is provided with an inner ring and is arranged on the boss on the inner ring on its Sealing matrix, therefore, when bigger, when the cylinder body relative movement, inner ring is extruded easily, thereby loses the effect of sealing in the cylinder body gap.
The model utility content
To the deficiency of existing technology, the utility model provides a kind of seal ring of good seal performance.
For realizing above-mentioned purpose, the utility model adopts following technological scheme:
A kind of rod seal part 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 the described inner ring of the utility model, 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 bigger power like this so that the adaptation cylinder body bigger extrude the gap.
The beneficial effect of the utility model is: simple in structure, increased stability, inner ring can bear bigger power so that adapt to cylinder body bigger extrude the gap.
Description of drawings
Fig. 1 is the structural representation of the utility model.
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
