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 first back-up ring and the second back-up ring, and also being provided with the cross section between described the first back-up ring and the second back-up ring is T-shaped boss.
In technique scheme, a kind of piston rod seal component, it comprises the first back-up ring and the second back-up ring, also being provided with the cross section between described the first back-up ring and the second back-up ring is T-shaped boss, therefore in installation and using process, be not easy the distortion upset, thereby guaranteed sealing effect.
Beneficial effect of the present invention is: simple in structure, in installation and using process, be not easy the distortion upset, good sealing effect.
Description of drawings
Fig. 1 is structural representation of the present invention.
Among the figure, 11 is the first back-up ring, and 12 is the second back-up ring, and 2 is boss.
Embodiment
Below by specific embodiment, the present invention is done detailed description.
Referring to Fig. 1, in technique scheme, a kind of piston rod seal component, it comprises the first back-up ring 11 and the second back-up ring 12, also being provided with the cross section between described the first back-up ring 11 and the second back-up ring 12 is T-shaped boss 2, therefore in installation and using process, be not easy the distortion upset, thereby guaranteed sealing effect.
