Abstract
The utility model relates to a connecting device for plastic rain pipes, composed of two pipes whose radial dimensions are different in the mode of integral connection. One type is that the pipes are circular pipes, and the internal diameter of one circular pipe is equal to the outer diameter of the other circular pipe; the other type is that the pipes are rectangular pipes, and the inner wall dimension of one rectangular pipe is the same as the outer wall dimension of the other rectangular pipe. The utility model has the advantages of easy installation and good sealing performance, and is an ideal connecting device for plastic rain pipes.
Description
The utility model relates to a kind of plastics rainwater pipe connector.
The present employed plastics rainwater of building pipe, cumbersome when mounted, generally be earlier an end that saves plastics rainwater pipe to be heated (being immersed in the deep fat or fiery baking), then another joint plastics rainwater pipe is inserted a heated end.Obviously, it installs difficulty.
The purpose of this utility model is at above-mentioned shortcoming of the prior art, and a kind of plastics rainwater pipe connector of easy for installation, good airproof performance is provided.
The purpose of this utility model is achieved in that it is connected as one and forms to the different pipe of size by two pitch diameters.
A kind of form is that described pipe is a round tube, and the internal diameter of a round tube equates with the external diameter of another round tube.
Another kind of form is that described pipe is a box section, and the inwall size of a box section is identical with the outer wall dimension of another box section.
The utility model has the advantages that easy for installation, good airproof performance.It is a kind of comparatively ideal plastics rainwater pipe connector.
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is the structural representation of embodiment 1 of the present utility model.
Fig. 2 is the structural representation of embodiment 2.
Fig. 3 is the left view of Fig. 2.
By embodiment shown in Figure 11 as can be known, it is connected as one by two round tubes 1,2 that save different-diameters and forms, and by the injection machine once-forming, the internal diameter of round tube 1 equates with the external diameter of round tube 2.Round tube 1 is isometric with round tube 2, is provided with 45 ° chamfering at an end of round tube 2, so that insert plastics rainwater pipe.
Fig. 2,3 is embodiment 2, and it is connected as one by two box sections 3,4 that save different chi rain and forms, but injection molded, and the inwall size of box section 3 is identical with the outer wall dimension of box section 4.The cross sectional shape of the box section shown in Fig. 2,3 is a square, and the inwall length of side of box section 3 equates with the box section 4 outer wall length of sides, is provided with 45 ° chamfering at an end of box section 4.
The cross sectional shape of box section 3,4 also can be rectangle, in this case, the long limit of the long limit of box section 3 inwalls and box section 4 outer walls is isometric, and the minor face of the minor face of box section 3 inwalls and box section 4 outer walls is isometric, is provided with 45 ° chamfering at an end of box section 4.
Claims (7)
1, a kind of plastics rainwater pipe connector is characterized in that it is connected as one and forms to the different pipe of size by two pitch diameters.
2, coupling according to claim 1 it is characterized in that described pipe is a round tube, and the internal diameter of a round tube equates with the external diameter of another round tube.
3, coupling according to claim 2 is characterized in that an end of the round tube that diameter is less is provided with chamfering.
4, coupling according to claim 1 it is characterized in that described pipe is a box section, and the inwall size of a box section is identical with the outer wall dimension of another box section.
5, coupling according to claim 4 is characterized in that the cross sectional shape of described box section is square.
6, coupling according to claim 4, the cross sectional shape that it is characterized in that described box section is a rectangle.
7,, it is characterized in that being provided with chamfering at an end of reduced size box section according to claim 5 or 6 described couplings.
