Description
Technical field
The utility model is related to drainage car field, more particularly to drainage vehicle extension tube.
Background technology
In the prior art, the water inlet pipe water pipe of drainage car is fixed structure, it is impossible to flexible, is caused, and it uses length ineffective
It is living, greatly reduce the actionradius of drainage car, and depth of implements.
Utility model content
Technical problem to be solved in the utility model is to provide drainage vehicle extension tube, increase drainage car depth of implements and
Radius, to solve caused above-mentioned multinomial defect in the prior art.
To achieve the above object, the utility model provides following technical scheme：Drainage vehicle extension tube, including inner tube and outer
Pipe, inner tube is arranged in outer tube, and inner tube is slidably connected relative to outer tube, and the tip inside of the outer tube is inwardly vertically provided with ring-type
Baffle plate, the end outside vertical of said inner tube is more than the external diameter of inner tube, ring-type to ring-type sliding block, the internal diameter of ring-shaped baffle is externally provided with
Sliding block.
Preferably, the outer tube is provided with ring-type fixed seat, and the inwall of ring-type fixed seat is provided with ring-type tetrafluoro plate, tetrafluoro
Plate is in contact with the outer wall of inner tube.
Preferably, water seal circle is provided with the inside of the ring-shaped baffle, water seal circle is in contact with the outer wall of inner tube.
Preferably, the ring-type sliding block outer wall is provided with O-ring, and O-ring is in contact with the inwall of outer tube.
Preferably, the bottom of the ring-type sliding block is provided with dust ring, and dust ring is in contact with the inwall of outer tube.
Beneficial effect using above technical scheme is：The drainage vehicle extension tube of the utility model structure, fixes water originally
Pipe is changed to the Shen draw, can control water inlet length of tube, increases vehicle depth of implements and radius；Shen compression process ensures its stability and close
Envelope property is good.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein, 1-- inner tubes, 2-- outer tubes, 3-- ring-shaped baffles, 4-- ring-types sliding block, 5-- ring-types fixed seat, 6-- ring-types four
Fluorine plate, 7-- water seals circle, 8--O types circle, 9-- dust rings.
Specific embodiment
Describe preferred embodiment of the present utility model in detail below in conjunction with the accompanying drawings.
Fig. 1 shows specific embodiment of the present utility model：Drainage vehicle extension tube, including inner tube 1 and outer tube 2, inner tube 1 set
Put in outer tube 2, inner tube 1 is slidably connected relative to outer tube 2, the tip inside of the outer tube 2 is inwardly vertically provided with ring-shaped baffle
3, the end outside vertical of said inner tube 1 is more than the external diameter of inner tube 1, ring to ring-type sliding block 4, the internal diameter of ring-shaped baffle 3 is externally provided with
Shape sliding block 4.
Be provided with ring-type fixed seat 5 inside outer tube 2, the inwall of ring-type fixed seat 5 is provided with ring-type tetrafluoro plate 6, tetrafluoro plate with it is interior
The outer wall of pipe 1 is in contact；The inner side of ring-shaped baffle 3 is provided with water seal circle 7, and water seal circle 7 is in contact with the outer wall of inner tube 1；Ring-type is slided
The outer wall of block 4 is provided with O-ring 8, and O-ring 8 is in contact with the inwall of outer tube 2；The bottom of ring-type sliding block 4 is provided with dust ring 9, dust ring
9 are in contact with the inwall of outer tube 2.
The drainage vehicle extension tube of the utility model structure, originally fixes water pipe and is changed to the Shen draw, can control water inlet length of tube,
Increase vehicle depth of implements and radius；Shen compression process ensures its stability and good airproof performance.
