Abstract
This utility model relates to the telescopic-pipe sealing structure of a kind of drainage car, including telescoping inner, outer telescopic tube, sealing snare and sealing ring glue, one limited block is arranged at the bottom of telescoping inner, described sealing snare contains a cushion rubber bumper, ring set is provided with one in the middle of the head of outer telescopic tube, sealing ring glue and fills chamber and a charging port, and sealing ring glue is embedded in sealing shroud, when filling intracavity non-filler, seal and have certain interval between snare and telescoping inner.This utility model is when telescoping tube stretches, telescoping inner will not glued joint tactile with sealing ring, sealing structure will not be damaged because of friction, seal structure only in the case of work, sealing ring is filled chamber and is just expanded, sealing ring glue is the most tightly embraced telescoping inner and is reached sealing function, has that stronger elasticity, sealing be good, simple in construction, cheap, reliable and stable is easily achieved again.
Description
Technical field
This utility model relates to a kind of drainage car, and the telescoping tube particularly relating to a kind of drainage car seals
Structure.
Background technology
There is bigger coaxiality error in the ring structure that the telescoping tube of drainage car uses at present,
Processing is got up more complicated and the most easy to wear, for solving this problem, and license notification number CN
The utility model patent of 201627922U discloses the telescopic-pipe sealing structure of a kind of drainage car,
It is characterized in that: being made up of screw, fixed cover and sealing ring, fixed cover is arranged on by screw
Between the inner and outer tubes of telescoping tube, sealing ring is arranged on fixed cover.But telescoping tube is in work
When making, its inner tube is in telescopic process, because pipeline circularity is uneven, easily with outer pipe friction, this
The sealing ring of sample is because contacting with telescoping inner wall always, the most wear-resisting, and is stretching
Cheng Zhong, capable of expansion and contraction being difficult to of inner tube to be allowed reaches.
Utility model content
For overcoming deficiency of the prior art, this utility model provides a kind of elastic strong, sealing
Property good, simple in construction, the drainage car being easily achieved again cheap, reliable and stable flexible
Tube seal structure.
For achieving the above object, the technical solution adopted in the utility model is as follows: a kind of drainage car
Telescopic-pipe sealing structure, including telescoping inner, outer telescopic tube, sealing snare and sealing ring glue,
One limited block is arranged at the bottom of telescoping inner, seals snare and contains a cushion rubber bumper, ring set
In the middle of the head of outer telescopic tube, sealing ring glue, it is provided with one fills chamber and a charging port, close
Seal glue is embedded in sealing shroud, when filling intracavity non-filler, seals snare and telescoping inner
Between have gap.
Further, described filling chamber is shaped as rectangle.
Further, described implant is oil or gas.
Seen from the above description, the telescoping tube of a kind of drainage car that this utility model provides seals knot
Structure, this utility model is when telescoping tube stretches, and telescoping inner will not glued joint tactile with sealing ring,
Sealing ring will not be damaged because of friction, seal structure only in the case of work, sealing ring
Filling chamber just to expand, sealing ring glue is the most tightly embraced inner tube and is reached sealing function, has stronger
Elastic, sealing good, simple in construction, cheap, reliable and stable be easily achieved again.

Figure.
Detailed description of the invention
Below by way of detailed description of the invention, the utility model will be further described.
As shown in figures 1-4, the telescopic-pipe sealing structure of a kind of drainage car, including telescoping inner 1,
Outer telescopic tube 2, sealing snare 3 and sealing ring glue 4, the bottom 11 of telescoping inner 1 has one spacing
Block 12, seals snare 3 and is contained in the head of outer telescopic tube 2 containing a cushion rubber bumper 31, sealing snare 3
Portion 21, is provided with one and fills chamber 41 and a charging port 42, sealing ring glue in the middle of sealing ring glue 4
4 are embedded in sealing snare 3, when filling non-filler in chamber 41, in sealing snare 3 and stretching
Gap is had between pipe 1.
As it can be seen, the telescopic-pipe sealing structure of a kind of drainage car is operationally, telescoping inner 1
When sliding into position required for operating mode, opening implant system, implant can be oil or gas,
Filling implant in filling chamber 41, because sealing ring glue 4 is elastic good, sealing ring glue 4 is at pressure
Effect is lower to be expanded, and is close to telescoping inner 1 wall, thus plays sealing function.
Above are only a detailed description of the invention of the present utility model, but design of the present utility model
Design is not limited thereto, all changes utilizing this design that this utility model carries out unsubstantiality,
The behavior invading this utility model protection domain all should be belonged to.
