Description

A kind of CPVC cable protection pipe quickly connected

Technical field

The utility model relates to a kind of plastic pipe, in particular to a kind of CPVC cable protection pipes quickly connected.

Background technique

CPVC pipe is chlorinated polyvinyl chloride tubes, is made of the modified material of polyvinyl chloride.With good insulating properties, resistance Combustion property, is one of lineation profile of cable protection pipe.But the connection of traditional CPVC cable protection pipe is not convenient enough, and can increase Add additional cost.It would therefore be desirable to a kind of can be completed the tubing being detachably connected without being equipped with additional attachment, thus Construction joint efficiency is effectively improved, difficulty of construction is reduced, reduces construction cost.

Utility model content

The purpose of this utility model is to provide for a kind of CPVC cable protection pipe quickly connected, the protection pipe structure letter Single, connection disassembling is convenient, does not need that secured, good airproof performance tubing connection can be completed using additional connector, effectively drops Low tubing construction and installation difficulty improve construction efficiency, reduce construction cost.

In order to achieve the above object, the utility model provides following technology and puts that: the CPVC cable that one kind quickly connects Protection pipe, including tube body, the outer wall of the tube body are coated with anti-aging paint, the both ends of the tube body be respectively equipped with connection bulge loop and Concave ring is connected, the connection bulge loop is equipped with the link block that at least two axial lengths extend, and the connection concave ring is equipped with extremely The fixation hole that few two axial lengths extend, the side of the link block are equipped with spring retainer groove, can in the spring retainer groove Disassembly installation spring, the link block include the limit section of the linkage section of axial length extension, circumferential lengths extension, the fixation Hole includes connecting cavity and limit chamber.

It is further preferred that the inside of the connection concave ring is equipped with slope.

It is further preferred that the cross section of the link block and fixation hole is sector, the widest part of the link block and company The cross section for connecing chamber is identical.

It is further preferred that sealing ring is arranged in upper and lower two sides gap after the connection bulge loop insertion connection concave ring.

The utility model has the beneficial effects that the protection pipe structure is simple, connection disassembling is convenient, does not need using additional company Secured, good airproof performance tubing connection can be completed in fitting, effectively reduces tubing construction and installation difficulty, improves construction effect Rate reduces construction cost.

Specific embodiment

We do in conjunction with the CPVC cable protection pipe that attached drawing quickly connects one kind described in the utility model into one below The explanation of step.

As shown in Fig. 1 to Fig. 5, the CPVC cable protection pipe that one kind of the present embodiment quickly connects, including tube body 1, institute The outer wall for stating tube body 1 is coated with anti-aging paint, and the both ends of the tube body 1 are respectively equipped with connection bulge loop 2 and connection concave ring 3, described It connects bulge loop 2 and is equipped with the link block 4 that at least two axial lengths extend, it is axial that the connection concave ring 3 is equipped at least two The fixation hole 5 that length extends, the side of the link block 4 are equipped with spring retainer groove 41, detachable in the spring retainer groove 41 Spring 42 is installed, the link block 4 includes the limit section 44 of the linkage section 43 of axial length extension, circumferential lengths extension, described Fixation hole 5 includes connecting cavity 51 and limit chamber 52.The inside of the connection concave ring 3 is equipped with slope 31.The link block 4 and fixation The cross section in hole 5 is sector, and the widest part of the link block 4 is identical as the cross section of connecting cavity 51.The connection bulge loop 2 is inserted into After connecting concave ring 3, sealing ring 6 is arranged in upper and lower two sides gap.

The connection type of the protection pipe is as follows: by the connection bulge loop of a tubing close to the connection concave ring of another tubing, by bullet After spring pressing, link block is inserted into the most inner side of fixation hole, then unclamps tubing and slowly rotates, so that limit section is inserted into limit chamber, The connection for completing two tubing, acting on not exert a force and limit section and be limited in limit chamber always due to spring, to guarantee The fastness of tubing connection.The leakproofness of tubing is improved by the setting of Double seal ring.

The protection scope of the utility model is not limited to above embodiments and its transformation.Those skilled in that art are with this implementation The conventional modification and replacement carried out based on the content of example, belongs to the protection category of the utility model.
