Anti-clogging drain pipe

Abstract

The invention provides an anti-clogging drain pipe, and belongs to the technical field of drain pipes. The problem that existing drain pipes having no dredging device is solved. The anti-clogging drain pipe comprises an inner pipe and an outer pipe, wherein an adjusting ring is arranged at the top end of the inner pipe, a plurality of arc-shaped mounting grooves are formed in an inner wall of the outer pipe, a hinge portion is arranged at one end of each mounting groove, a plurality of arc-shaped punched holes are formed in the inner pipe, an anti-clogging rod with a pin fixedly arranged at one end is comprised, the pin is movably connected with the hinge portion, an outer wall of the inner pipe props up an anti-clogging rod, so that the entire anti-clogging rod is arranged in the mounting groove, a torsional spring is arranged between the pin and the hinge portion, the adjusting ring can be rotated clockwise to drive the inner pipe to rotate, so that the mounting groove is aligned with a perforated hole, the torsional spring drives the anti-clogging rod to rotate around the pin, so that the anti-clogging rod stretches into the inner pipe, the inner pipe is rotated clockwise continuously, so that a hole wall at one end of the perforated hole props up a rod wall of the anti-clogging rod and drives the anti-clogging rod to rotate, and finally the anti-clogging rod is reset in the mounting groove. The anti-clogging drain pipe is provided with an anti-clogging structure, and can be dredged quickly, and influence on normal drainage can be avoided.

Description

technical field [0001] The invention belongs to the technical field of drainage pipes, and relates to an anti-blocking drainage pipe. Background technique [0002] Existing drainage pipes are generally used to drain rainwater from roofs. Once blocked, additional tools are needed to unclog them, which is very troublesome. It is impossible to make the drainage pipes themselves have a dredging device and use themselves to dredge them. Therefore, it is necessary to improve. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned problems in the prior art, and provide an anti-blocking drainage pipe that will not affect the drainage effect and can be quickly unblocked when the drainage pipe is blocked. [0004] The purpose of the present invention can be achieved through the following technical solutions: an anti-blocking drainage pipe, including a vertically arranged drainage pipe, is characterized in that: the drainage pipe includ...
