Improved multifunctional drainage pipe

Abstract

The invention provides an improved multifunctional drainage pipe, and belongs to the field of drainage pipes. By adoption of the improved multifunctional drainage pipe, the problem that an existing drainage pipe does not have an anti-theft function or an anti-blocking function is solved. The improved multifunctional drainage pipe comprises a drainage pipe body. The drainage pipe body comprises an inner pipe and an outer pipe. An adjustment ring is arranged at the top end of the inner pipe. The inner pipe and the outer pipe are provided with a plurality of through holes and a plurality of installation holes correspondingly. A hinge part is arranged at one end of each installation hole. The drainage pipe body further comprises fan-shaped movable plates. Inner thorns and outer thorns are formed on the movable plates. Dowels are fixed to the movable plates and movably connected to the hinge parts. Torsional springs are arranged between the dowels and the hinge parts. The through holes communicate with the installation holes in a flush mode. The movable plates are swung by the torsional springs to be embedded into the through holes, so that the inner thorns are made to stretch into the inner wall of the inner pipe; and the torsional springs can also rotate clockwise to adjust the inner pipe, so that one ends, in the length direction, of the through holes are made to push the radius edges of the movable plates, the movable plates are made to rotate outwards around the dowels, the outer thorns are made to protrude out of the outer wall of the outer pipe, and the through holes and the installation holes can be mutually sealed. The improved multifunctional drainage pipe has the anti-theft function and the anti-blocking function.

Description

technical field [0001] The invention belongs to the technical field of drainage pipes and relates to an improved multifunctional drainage pipe. Background technique [0002] Existing drainage pipes are generally used to drain rainwater from roofs, and the problems of anti-theft and anti-blocking need to be solved. Therefore, the structure of the existing drainage pipes is very complicated, and at the same time, the problems of anti-theft and anti-blocking cannot be well solved, so 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 improved multifunctional drainage pipe that can prevent theft and blockage, and is convenient to switch back and forth between the two functions. [0004] The purpose of the present invention can be achieved through the following technical solutions: an improved multifunctional drainage pipe, including a vertically arranged dr...
