Description
Technical field
This utility model relates to the drainage fitting in a kind of building or structures, is specifically related to a kind of assembled telescopic joint.
Background technology
Riser tube in current building or structures need to install a Simple telescopic joint or screw telescopic joint every 4 meters, lower end adopts adhesive to connect, upper end adopts and flexibly connects, the bad installation when installing upper end and flexibly connecting, tubing is not easily inserted in flexible telescopic joint bellmouth, the port of tubing need to be carried out chamfered, also need being coated with lubricant in tubing spigot, pipe fitting bellmouth, tubing so just can be made to insert in pipe fitting bellmouth smoothly, installation process difficulty, efficiency of construction is low, both time-consuming, takes a lot of work again.
Utility model content
This utility model aims to provide a kind of assembled telescopic joint, its simple in construction, and practical reliable, mounting or dismounting are convenient, and efficiency of construction is high.
The technical solution of the utility model is a kind of assembled telescopic joint, including upper external member, cup lid group and expanding ring, described upper external member is ladder tubular, and upper end difference diameter is more than downstairs portion diameter, upper end difference internal diameter is suitable with drain pipe external diameter, and downstairs portion external diameter is suitable with cup lid group internal diameter；Described cup lid group diameter of bore is suitable with drain pipe external diameter, and endoporus top is provided with annular groove, arranges O in annular groove, is provided with bellmouth in the middle part of endoporus；Described expanding ring is the open annular circle being sheathed on external member outer surface, and expanding ring internal diameter is suitable with downstairs portion external diameter.
Preferably, described bellmouth is the collar flange closed, the external diameter of the collar flange internal diameter external diameter less than downstairs portion and drain pipe.
Preferably, the downstairs portion of described upper external member is up big and down small taper, the angle that bus and axis are formed more than 1 ° less than or equal to 10 °.
This utility model simple in construction, safe and reliable, meet, while adopting the convenient installation of fabricated structure, the requirement occurring expanding with heat and contract with cold in the actually used process of drain pipe, be suitable in industry and apply.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is further elaborated.
As shown in Figures 1 to 7, the utility model discloses a kind of assembled telescopic joint, including upper external member 1, cup lid group 2 and expanding ring 3, described upper external member 1 is ladder tubular, upper end difference 4 diameter is more than downstairs portion 5 diameter, upper end difference 4 internal diameter is suitable with drain pipe external diameter, and downstairs portion 5 external diameter is suitable with cup lid group 2 internal diameter；Described cup lid group 2 diameter of bore is suitable with drain pipe external diameter, and endoporus top is provided with annular groove 6, arranges O 8 in annular groove 6, is provided with bellmouth 7 in the middle part of endoporus；Described expanding ring 3 is the open annular circle being sheathed on external member 1 outer surface, and expanding ring 3 internal diameter is suitable with downstairs portion 5 external diameter.
Preferably, bellmouth 7 is the collar flange closed, the external diameter of the collar flange internal diameter external diameter less than downstairs portion 5 and drain pipe.
Preferably, the downstairs portion 5 of upper external member 1 is up big and down small taper, the angle that bus and axis are formed more than 1 ° less than 10 °.
During use, expanding ring 3 is enclosed within downstairs portion 5 outer surface of upper external member 1, upper external member 1 is loaded in cup lid group 2, in upper external member 1 bottom end face distance cup lid group 2 endoporus, the height of bellmouth 7 upper surface is the height of expanding ring 3, taking and discharging pipe outer pipe wall inserts in upper end difference 4 endoporus of upper external member 1 after smearing PVC glue, drain pipe pipe end is positioned in shoulder hole, insert from cup lid group 2 endoporus after another root drain pipe tubing is smeared PVC glue simultaneously, drain pipe tubing is positioned at bellmouth 7 lower surface, also can smear PVC glue in the external member relevant position contacted with tubing simultaneously, all connect and take off expanding ring 3 after installing, namely this installation process is completed, whole process need not be rule by outer pipe wall again, regulate the operations such as insertion depth.Axial gap between upper external member 1 and cup lid group 2 is exactly the height of expanding ring 3, and this axial gap is left drain pipe tubing for and expanded with heat and contract with cold and produce axial length change use, and whole installation process is convenient and simple, safe and reliable.
