Abstract
The invention relates to parts of a vehicle, in particular to a hydraulic piston cylinder. The hydraulic piston cylinder comprises a cylinder body which is internally provided with two vertically arranged oil pressure chambers. A connecting chamber is arranged between the two oil pressure chambers. The upper part of the connecting chamber is cone-shaped and the lower part of the connecting chamber is cylindrical. A circular sunk groove is arranged outside the cylinder body. The circular sunk groove is provided with a plurality of sealing rings. Fixed locking rings are arranged outside the sealing rings. A circular bump structure is arranged inside the oil pressure chamber close to one side of the cylindrical connecting chamber. The hydraulic piston cylinder provided by the invention is novel in structural design and high in sealing performance.
Description
Technical field
The present invention relates to a kind of auto parts and components, specifically relate to a kind of hydraulic piston tube.
Background technique
In the existing technology, automobile is used the hydraulic piston structure, and its application is comparatively extensive, for example braking system etc.
Summary of the invention
To the technical problem that exists in the existing technology, the invention provides a kind of simple in structure, hydraulic piston tube that sealability is high.
To achieve these goals, the technological scheme that the present invention adopted is following:
A kind of hydraulic piston tube is characterized in that, comprises cylindrical shell, is provided with two in the cylindrical shell and is the oil pressure chamber of vertically arranging, and is provided with the connection chamber between two oil pressure chambers, connects chamber top and is cone table shape, and it is cylindric that the bottom is; The cylindrical shell outside is provided with the ring-shaped depression groove, is provided with a plurality of seal rings in the ring-shaped depression groove, and the outside of seal ring is provided with fixedly snap ring.
Further, the inboard near the oil pressure chamber of cylindric connection chamber one side has the annular projection structure.
Hydraulic piston tube of the present invention, structural design is novel, and sealability is high.
Description of drawings
For the ease of it will be appreciated by those skilled in the art that the present invention is further described below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present invention.
Embodiment
See also Fig. 1, a kind of hydraulic piston tube comprises cylindrical shell 7, is provided with two in the cylindrical shell 7 and is between the oil pressure chamber of vertically arranging 1 and 8, two oil pressure chambers of oil pressure chamber and is provided with the connection chamber, connects chamber top and is cone table shape 2, and the bottom is cylindric 3.
Simultaneously, the inboard (a relative side) of oil pressure chamber 1 and oil pressure chamber 8 has annular projection structure 4.
Above content only is to give an example and explanation to what structure of the present invention was done; Under the technician in present technique field described specific embodiment is made various modifications or replenish or adopt similar mode to substitute; Only otherwise depart from the structure of invention or surmount the defined scope of these claims, all should belong to protection scope of the present invention.
Claims (2)
