The positioning protrusion is embedded into including one in inner wall of the pipe connecting cylinder as a further improvement of the utility model,
Tabs.
As a further improvement of the utility model, the inner wall of the seal rubber sleeve be divergent structure, flared end it is interior
Diameter is less than the internal diameter of sealing collar, and the flared end of seal rubber sleeve is towards seal rubber sleeve top-pushing mechanism.
The utility model has the beneficial effects that：
1, the utility model replaces original sealing rubber ring, the bullet of seal rubber sleeve utilized itself by a seal rubber sleeve
Seal rubber sleeve is socketed on pipe to be connected by property using a pushing tow ring, compared to sealing ring contact area bigger, and not
It is easy seal rubber sleeve and damaged or fracture is less likely to occur compared to sealing rubber ring, and when pipe insertion, the part of inner wall is ground
Damage will not influence sealing of the whole section of seal rubber sleeve to tubing, and effect is more preferable.
2, bracing ring is connected through a screw thread, can be replaced according to the tubing of different wall thickness different inner wall of the pipe connecting cylinders and
Seal rubber sleeve, it is simple and convenient, when the positioning protrusion of setting can prevent pipeline from connecting, because whole caused by the rotary force of pushing tow ring
Body threaded connector loosens.
3, positioning protrusion can realize inner wall of the pipe and fix, and during preventing connection, pipeline retinue rotation causes close
It binds the loosening of circle.
4, the seal rubber sleeve of divergent structure improves the thickness of end, while ensureing seal rubber sleeve variable amplitude, carries
The high effect of sealing.
