Utility model content
The utility model is to overcome at least one defect described in above-mentioned prior art, there is provided a kind of integral telescopic section,
Gland is eliminated, reduces injection and installation procedure, reduces production cost, improves product competitiveness.
In order to solve the above technical problems, the technical solution of the utility model is as follows：
A kind of integral telescopic section, including telescopic joint main body and sealing ring, the telescopic joint main body are hollow tubulose knot
Structure, its one end is holds downstream, and the other end is end facing water, and the telescopic joint main body is integral type injection molding structure, and it includes suitable
Water portion is all higher than the portion of meeting water with the portion that meets water, the downstream internal diameter in portion and external diameter, and the inwall in portion is provided with a groove downstream, and sealing ring is embedding
Enter in the groove.
In a kind of preferable scheme, the groove is rectangular channel.
In a kind of preferable scheme, the inwall of the sealing ring is provided with some broached-tooth designs.
In a kind of preferable scheme, the broached-tooth design is extended internally from sealing ring inwall and inclined to the portion direction of meeting water
Tiltedly.Downstream behind portion, the broached-tooth design meeting resilience of sealing ring compresses tubing, avoids seepy question for tubing insertion.
In a kind of preferable scheme, the outer wall in the portion that meets water is provided with a circle telescopic joint locating snap ring, and the telescopic joint stops
Rotating ring is raised in the outer wall in the portion of meeting water.The effect of telescopic joint locating snap ring is easy for pipe clamp and is fixedly clamped to use on the wall.
Compared with prior art, the beneficial effect of technical solutions of the utility model is：The utility model provides a kind of one
Formula telescopic joint, including telescopic joint main body and sealing ring, the telescopic joint main body are hollow tubular structure, and its one end is downstream
End, the other end is end facing water, and the telescopic joint main body is integral type injection molding structure, and it includes portion downstream and the portion that meets water, suitable
The internal diameter and external diameter in water portion are all higher than the portion of meeting water, and the inwall in portion is provided with a groove downstream, and sealing ring is embedded in the groove.This
The sealing ring of utility model integral telescopic section is directly embedded into the groove, eliminates gland, reduces injection and installation procedure,
Production cost is reduced, improves product competitiveness.After tubing insertion is held downstream, sealing ring meeting resilience compresses tubing, avoids leak from asking
Topic occurs.
