Abstract
The utility model discloses a piston in an oil cylinder. The piston comprises a cylinder seat, wherein an oil inlet is formed in the cylinder seat; a cylinder body is hermetically arranged on the cylinder seat; a piston and a piston rod on the piston are slidably arranged in the cylinder body; stepped surfaces are arranged at a contact surface of the piston and the cylinder seat and the surface of the cylinder seat; and the piston is hermetically connected with the inner wall of the cylinder body through a Yx type seal ring and a G type seal ring. The piston has a simple structure, but dead zones existing on a junction surface of the piston and the cylinder seat can be completely removed, so that the phenomenon that the oil cylinder is slow in starting or cannot be started during starting is improved.
Description
Technical field
The utility model relates to technical field of hydraulic elements, and concrete is piston in a kind of oil cylinder.
Background technique
In common oil cylinder, oil cylinder tends to occur slowly or the phenomenon that can not start when starting, and this all is because there is a dead band in the junction plane of piston and cylinder seat, yet, in this dead band, also exist hydraulic oil with its adhesion; Just above phenomenon can appear.
The model utility content
The purpose of this utility model is exactly the dead band of thoroughly removing the junction plane existence of piston and cylinder seat, tends to occur slowly or the phenomenon that can not start when starting thereby improve oil cylinder.
The technical solution of the utility model:
Piston in the oil cylinder, comprise the cylinder seat, the cylinder seat is provided with filler opening, it is characterized in that: be sealed and installed with cylinder body on the described cylinder seat, be slidingly fitted with the piston rod on piston and the piston in the cylinder body, have step surface on the surface of described piston and cylinder seat surface of contact place, cylinder seat.
Piston in the described oil cylinder is characterized in that: be tightly connected by Yx RunddichtringO, G RunddichtringO between the inwall of described piston and cylinder body.
Advantage of the present utility model:
The utility model is simple in structure, but can thoroughly remove the dead band of the junction plane existence of piston and cylinder seat, tends to occur slowly or the phenomenon that can not start when starting thereby improve oil cylinder.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
