Embodiment
Existing with reference to accompanying drawing, further explain the utility model.
With reference to accompanying drawing 1; A kind of PVC drain pipe movable telescopic joint comprises interconnecting piece 1 and outer connector 2, and said interconnecting piece 1 comprises two wedge shape semicircular ring; Two said wedge shape semicircular ring are closed up becomes an annulus; Said interconnecting piece 1 inwall middle part is provided with a positioning ring 21, and said positioning ring 21 is provided with around said interconnecting piece 1 inwall middle part, and said outer connector 2 is a wedge mouth annulus; The outer wall of the end that said wedge mouth annulus opening is bigger is provided with screw thread, and is provided with the movable telescopic pitch circle ring cap 4 that is complementary with said screw thread; The inwall of the end that said wedge mouth annulus opening is bigger is provided with seal ring 3, said interconnecting piece external diameter and said outer connector internal diameter coupling, and said interconnecting piece places in the said outer connector and through the PVC glue special and connects.
With reference to accompanying drawing 4, when the utility model is installed, the PVC blow-off line that two ends are fixing is installed the movable telescopic joint in the centre.The first step cuts out the room in the middle of fixing pipeline; The length in room is greater than the length of movable telescopic joint outer connector 2; In second step, above the pipeline room, be inserted in annulus cap 4 and seal ring 3; In the 3rd step, the pvc pipe of cutting suitable length adopts a movable joint to connect below the pipeline room, reserves extendable room during installation; In the 4th step, movable telescopic is saved interconnecting piece 1 lower end inwall brush PVC glue special, and close up and be buckled in the pipe coupling position; The 5th step, at movable telescopic joint interconnecting piece 1 Brush for outer wall PVC glue special, movable telescopic is saved outer connector 2 move that to be enclosed within interconnecting piece 1 outer and apply certain force and make outer connector 2 and interconnecting piece 1, interconnecting piece 1 is combined closely with pipeline; The 6th goes on foot, and rubber sealing ring 3 is moved be inserted in the outer connector 2, and annulus cap 4 outer connectors 2 of will living pass through screwed.
Each movable telescopic joint accordingly with a supporting use of movable joint.
Above-described the utility model mode of execution does not constitute the qualification to the utility model protection domain.The modification of being done within any spirit and principle at the utility model, be equal to replacement and improvement etc., all should be included within the claim protection domain of the utility model.
