Abstract
The invention discloses a kind of built-up pistons, including sealing ring, it further include cylinder and two pipe sleeves, the sealing snare is on the cylinder, the both ends of the cylinder are provided with screw thread, two pipe sleeves are threadedly attached on the both ends of the cylinder, and the sealing ring is clamped and fixed between two pipe sleeves.When needing that sealing ring is installed, pipe sleeve then can be screwed in from the both ends of cylinder respectively, the sealing ring is fixedly clamped between the pipe sleeve, this completes the installation of sealing ring, this structure, sealing ring is installed very simple first by sealing snare on cylinder.
Description
Technical field
The present invention relates to a kind of built-up pistons.
Background technique
Most important hydraulic motor is exactly to seal, and original sealing means are slotted on piston, then setting in slot again
The mode of sealing ring is realized, but this scheme, there are a defect, original sealing ring packs into very difficult in slot, installation
It is inconvenient, it is therefore necessary to be improved.
Summary of the invention
For the deficiencies in the prior art, the present invention provides a kind of built-up pistons, can put convenient installation
Sealing ring.
The present invention is achieved through the following technical solutions: a kind of built-up piston, including sealing ring, further include cylinder and
Two pipe sleeves, for the sealing snare on the cylinder, the both ends of the cylinder are provided with screw thread, and two pipe sleeves pass through spiral shell
Line is connected on the both ends of the cylinder, and the sealing ring is clamped and fixed between two pipe sleeves.Need to install sealing
When circle, pipe sleeve then can be screwed in from the both ends of cylinder respectively, the sealing ring is clamped solid first by sealing snare on cylinder
It is scheduled between the pipe sleeve, this completes the installation of sealing ring, this structure, sealing ring is installed very simple.
In above-mentioned technical proposal, it is preferred that the cylinder is a cylindrical body, the end of described sleeve pipe and the cylinder
End flushes.
In above-mentioned technical proposal, it is preferred that the diameter of two pipe sleeve outer rings is identical.
It, can be first by sealing snare on cylinder, then when the invention has the following beneficial effects: needing to install sealing ring
Pipe sleeve is screwed in from the both ends of cylinder respectively, the sealing ring is fixedly clamped between the pipe sleeve, this completes sealing rings
Installation, this structure, sealing ring installation it is very simple.
Detailed description of the invention
Fig. 1 is schematic cross-sectional view of the invention.
Fig. 2 is structural schematic diagram of the invention.
Specific embodiment
Present invention is further described in detail with specific embodiment with reference to the accompanying drawing:
Referring to Fig. 1-2, a kind of built-up piston, including sealing ring 1, it further include cylinder 2 and two pipe sleeves 3, two pipe sleeves
The diameter of outer ring is identical.
The both ends of the cylinder 2 are provided with screw thread 21,1 set of the sealing ring on the cylinder 2, two pipe sleeves 3
It is threadedly attached on 2 both ends of cylinder, the both ends of the sealing ring 1 are clamped and fixed between two pipe sleeves 3.
The cylinder is a cylindrical body, and the end of described sleeve pipe is flushed with the end of the cylinder.
It, can be first by sealing snare on cylinder, then respectively from the both ends spinning in pipe of cylinder when needing that sealing ring is installed
Set, the sealing ring is fixedly clamped between the pipe sleeve, this completes the installation of sealing ring, this structure, and sealing ring
It installs very simple.
