Description

Technical Field

[0001] The utility model relates to a downpipe, in particular to a downpipe for a toilet. Background Art

[0002] Polyvinyl chloride (PVC) is widely used in the manufacture of household decoration drainage pipes. The existing technology can use three 45-degree PVC elbows with an outer diameter of 110 mm to splice a toilet drain pipe through a 110 mm PVC straight pipe, and connect the toilet drain pipe to the 110 water pipe branch outlet at the entrance to the house for toilet sewage discharge. However, the disadvantage of this technology is that there are three joints on the outside of the toilet drain pipe and six joints on the inside. The internal joints cause the inner wall of the pipe to be discontinuous and rough, and debris may be retained and bonded at the connection. Long-term accumulation will cause the pipeline to be blocked or even easy to clog, and the installation is more troublesome, more material-consuming, and it is not easy to measure and control the pit distance. Summary of the invention

[0003] In order to overcome the above-mentioned deficiencies in the prior art, the utility model provides a toilet drain pipe. The utility model is used for installing a PVC sewage pipe of a floor-standing toilet in a household caisson bathroom.

[0004] The utility model solves the technical problem by adopting the following technical solution: a toilet drain pipe, characterized in that it comprises a joint (1), an elbow (2), a straight pipe (3), and a level ruler (4); the joint (1) is 45 mm long, is a water pipe with a smooth inner wall made of polyvinyl chloride (PVC) material, and can be tightly sleeved with a polyvinyl chloride (PVC) water pipe with an outer diameter of 110 mm on the inner side; the elbow (2) is a water pipe with an outer diameter of 110 mm and a smooth inner wall made of polyvinyl chloride (PVC) material; the elbow (2) is a water pipe with an arc shape of 45 degrees to the left in the horizontal plane after welding the joint (1), then welds a water pipe with an arc shape of 90 degrees upward, and then continues to weld the straight pipe (3); the straight pipe (3) is a cylindrical water pipe with an outer diameter of 110 mm and a smooth inner wall made of polyvinyl chloride (PVC) material; one end of the level ruler (4) is welded to the outer side of the junction of the elbow (2) and the straight pipe (3), and the other end is welded to the outer side of the junction of the elbow (2) and the straight pipe (3). One end extends toward the wall (9); the upper surface of the level ruler (4) is marked with scale, contains liquid, and has bubbles (5); the level ruler (4) is perpendicular to the wall (9), the axis of the joint (1), and the axis of the straight pipe (3); a sewage main pipe (6), an exhaust pipe (7), and a waste main pipe (8) made of polyvinyl chloride (PVC) material with an outer diameter of 110 mm are installed at the foot of the caisson toilet wall; the exhaust pipe (7) and the waste main pipe (8) are connected by an inclined pipe (10); the sewage main pipe (6) is connected to the sewage branch pipe (12) in the horizontal direction, so that the sewage branch pipe (12) is parallel to the wall surface (9); the waste discharge main pipe (8) is connected to the waste discharge branch pipe (11) in the horizontal direction, so that the waste discharge branch pipe (11) is perpendicular to the wall surface (9); the joint (1) can be sleeved with the sewage branch pipe (12); the curved pipe (2) and the straight pipe (3) are connected and the inner surface is smooth, continuous and of equal diameter.

[0005] The beneficial effects of the utility model are:
