Description

Detachable double-layer sleeved PVC pipe

Technical Field

The utility model relates to a circuit engineering technical field especially relates to a detachable bilayer cup joints PVC pipe.

Background

The PVC pipe is a hard PVC pipe, by polyvinyl chloride resin and stabilizer, use hot pressing extrusion molding after the cooperation of emollient etc., it is the plastic pipe who obtains development and application at the earliest, the PVC pipe corrosion resistance is strong, easily bond, low price, the texture is hard, a plurality of acceptance criteria have in light current water and electricity engineering, one of them acceptance criteria must wear the PVC pipe for all electrical apparatus control lines and circuits of requirement to circuit engineering, directly pass electrical apparatus control line and circuit PVC pipe, if when the outside temperature of PVC pipe reduces, can make the inside of PVC pipe form the water dew under the influence that outside temperature reduces, this water dew can corrode the extexine of electrical apparatus control line and circuit, thereby influence the life of electrical apparatus control line and circuit, coupling mechanism is complicated between two PVC bell and spigot pipes among the prior art, inconvenient dismantlement and installation.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects of inconvenient installation and disassembly between the double-layer sleeving pipes in the prior art, and providing a detachable double-layer sleeving PVC pipe.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the design is detachable double-deck PVC pipe of cup jointing, including the outer tube, the inner tube has been placed in the outer tube, the lantern ring has been cup jointed in the inner tube outside, open lantern ring side has a plurality of screw holes, and is a plurality of the screw hole is along lantern ring circumference evenly distributed, screw hole female connection has the threaded connection pole, the lantern ring one end fixedly connected with supporting mechanism is kept away from to the threaded connection pole.

Preferably, the supporting mechanism comprises an arc-shaped block, an arc-shaped surface in the arc-shaped block is abutted to the inner side wall of the outer sleeve, and a telescopic mechanism is installed between the arc-shaped block and the threaded connecting rod.

Preferably, telescopic machanism includes the sleeve, the spring has been placed in the sleeve, spring one end and arc piece fixed connection, the other end fixedly connected with slide bar of spring, the slide bar is located the sleeve, sleeve one end and threaded connection pole fixed connection are kept away from to the slide bar.

Preferably, a rubber ring is bonded on the inner side of the lantern ring.

Preferably, the outer side of the inner pipe is sleeved with a plurality of lantern rings, and the lantern rings are uniformly distributed along the axial direction of the inner pipe.

The utility model provides a detachable double-deck PVC pipe of cup jointing, beneficial effect lies in:

1. the utility model increases the contact surface between the telescopic mechanism and the outer sleeve by arranging the arc surface in the arc block, thereby avoiding the telescopic mechanism from damaging the outer sleeve from the inner side;

2. the utility model is provided with the telescopic mechanism, the outer sleeves with different pipe diameters can be sleeved outside the inner pipe, so that the selectable range is enlarged when the outer sleeve is replaced;

3. the utility model discloses a set up the rubber circle, avoid threaded connection pole and inboard lateral wall direct contact, damage the inner tube lateral wall.
