Abstract
The invention discloses built-up pistons, including sealing ring, it further include cylinder and two pipe sleeves, the sealing snare is on the cylinder, the pipe sleeve covers at the both ends of the cylinder, it is provided with first through hole on each pipe sleeve, second through-hole communicated with the first through hole is provided on the cylinder, bolt penetrates in second through-hole after being inserted into the first through hole.When needing that sealing ring is installed, it can be first by sealing snare on cylinder, then pipe sleeve is inserted in from the both ends of cylinder respectively, the sealing ring is fixedly clamped between the pipe sleeve, then bolt is inserted into first through hole again, this completes the installation of sealing ring, this structure, sealing ring is installed very simple.
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 built-up piston, convenient installation sealing can be put
Circle.
The present invention is achieved through the following technical solutions: built-up piston, including sealing ring, further includes cylinder and two
Pipe sleeve, on the cylinder, the pipe sleeve is covered to be provided with the sealing snare on the both ends of the cylinder, each pipe sleeve
First through hole, second through-hole communicated with the first through hole is provided on the cylinder, and bolt insertion described first is logical
It is penetrated behind hole in second through-hole.It, can be first by sealing snare on cylinder, then respectively from column when needing that sealing ring is installed
Pipe sleeve is inserted at the both ends of body, and the sealing ring is fixedly clamped between the pipe sleeve, bolt is then inserted into first through hole again
Interior, 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
It is inserted in pipe sleeve from the both ends of cylinder respectively, the sealing ring is fixedly clamped between the pipe sleeve, is then again inserted into bolt
In first through hole, this completes the installation of sealing ring, this structure, sealing ring is installed 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.
1 set of the sealing ring on the cylinder 2, two pipe sleeves 3 are connected on 2 both ends of cylinder, described close
The both ends of seal 1 are clamped and fixed between two pipe sleeves 3.First through hole 31 is provided on each pipe sleeve 3, it is described
Second through-hole 21 communicated with the first through hole 31 is provided on cylinder 2, bolt 4 is worn after being inserted into the first through hole 31
Enter in second through-hole 21.
When needing that sealing ring is installed, pipe then can be inserted in from the both ends of cylinder respectively first by sealing snare on cylinder
Set, the sealing ring is fixedly clamped between the pipe sleeve, then bolt is inserted into first through hole again, this completes close
The installation of seal, this structure, sealing ring installation are very simple.The cylinder be a cylindrical body, the end of described sleeve pipe with
The end of the cylinder flushes.
