Description
Technical field
The utility model belongs to pipe fitting technical field, is related to a kind of concertina type PVC pipe.
Background technique
Currently, common pipe fitting connection type is added by the way that small pipe fitting to be inserted into big pipe fitting, and by winding band
Strong ties intensity and leakproof are aqueous；But band will appear aging after long-term use, cause pipe fitting setting up and down in weight
Under power effect, underlying pipe fitting will appear loosening, or even the case where fall off.
Summary of the invention
The purpose of this utility model is the presence of the above problem in view of the prior art, proposes a kind of concertina type PVC pipe,
The utility model has the characteristics that flexible.
The purpose of this utility model can be realized by the following technical scheme: a kind of concertina type PVC pipe, feature exist
In including outer tube and inner tube, inner tube are in outer tube and are coaxially fixed by connection ring, and limit is provided on the outside of outer tube end
Ring, is provided with sealing ring between connection ring and stop collar, the outer ring of the sealing ring is close to the inner wall of outer tube.
The outer ring of the connection ring and the inner wall of outer tube are mutually fixed, and the inner ring of connection ring is mutually fixed with the outer wall of inner tube.
Screw thread one is offered on the outside of the outer tube end, the stop collar has screw thread two, limits global outer tube end
It is threadedly coupled.
Said inner tube and outer tube are all made of PVC and are made.
The sealing ring is made of rubber.
The sealing ring outer diameter is greater than the internal diameter of stop collar, and the internal diameter of stop collar is greater than the outer diameter of inner tube.
Anti-skid design is provided on the outside of the stop collar.
The base fabric working principle and application method of this concertina type PVC pipe are such that existing tube body being inserted into this
In utility model, the outer wall of sealing ring and tube body is closely pasted, and tube body is set in outside inner tube, since sealing ring is made of rubber, institute
There is certain elasticity with sealing ring, sealing ring can slidably reciprocate in outer tube, and tube body and inner tube can generate relative displacement, from
And realize Telescopic；In long-time service, if the case where generating loosening under the effect of gravity, automatic by rubber ring
Adjust, avoid existing tube body from falling off with this concertina type PVC pipe, and sealing ring waterproof effect with respect to sealing
Band is preferably.
Compared with prior art, the utility model has the advantage that
1, the utility model makes have cavity between outer tube and inner tube by setting outer tube and inner tube, and sealing ring can be
It is slided in cavity, can be mobile with sealing ring when existing tube body being made to be sealing ring connection, to have Telescopic.
2, the utility model enables the fixation that inner and outer tubes are stable by setting connection ring.
3, the utility model makes sealing ring have the advantages that will not fall off in sliding by setting stop collar.
4, the utility model substantially increases the performance for preventing leak by setting sealing ring.
Detailed description of the invention
Fig. 1 is the cross-sectional view of the utility model.
In figure, 1, outer tube；2, inner tube；3, connection ring；4, stop collar；5, sealing ring；6, tube body.
Specific embodiment
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these examples.
As shown in Figure 1, a kind of concertina type PVC pipe, including outer tube 1 and inner tube 2, inner tube 2 are in outer tube 1 and pass through company
Ring 3 is connect coaxially to fix, restraining position ring block 4 is arranged in the outside of 1 end of outer tube, sealing ring 5 is provided between connection ring 3 and stop collar 4,
It is close to the inner wall of outer tube 1 outer ring of sealing ring 5.
The outer ring of connection ring 3 and the inner wall of outer tube 1 are mutually fixed, and the inner ring of connection ring 3 is mutually fixed with the outer wall of inner tube 2.Outside
Screw thread one is offered on the outside of 1 end of pipe, stop collar 4 has screw thread two, the connection of 4 space outer tube of stop collar, 1 end thread.Inner tube 2
PVC is all made of with outer tube 1 to be made.Sealing ring 5 is made of rubber.5 outer diameter of sealing ring is greater than the internal diameter of stop collar 4, stop collar 4
Internal diameter be greater than inner tube 2 outer diameter.The outside of stop collar 4 is provided with anti-skid design.
The base fabric working principle and application method of this concertina type PVC pipe are such that existing tube body 6 being inserted into this
In utility model, sealing ring 5 and the outer wall of tube body 6 are closely pasted, and tube body 6 is set in outside inner tube 2, since sealing ring 5 uses rubber system
At so sealing ring 5 has certain elasticity, sealing ring 5 can slidably reciprocate in outer tube 1, and tube body 6 can be generated with inner tube 2
Relative displacement, to realize Telescopic；In long-time service, if the case where generating loosening under the effect of gravity, leads to
Rubber ring automatic adjustment is crossed, avoids existing tube body 6 from falling off with this concertina type PVC pipe, and the preventing water leakage of sealing ring 5
Effect is opposite preferable with band.
