Floor drain with grate, water trap and movable cover capable of being screwed out integrally

Abstract

A floor drain with a grate, a water trap and a movable cover capable of being screwed out integrally comprises a grate frame, lug pieces, lug piece L-shaped grooves, an outer pipe, an inner pipe, a convex ring, the movable cover, an annular concave part, a water blocking pipe and the grate. The floor drain is characterized in that the water blocking pipe is arranged at the bottom face of the grate; the portion, above the water blocking pipe, of the grate is closed; the annular concave part and the inner pipe are integrated; the convex ring is disposed on the inner wall of the lower half portion of the inner pipe; the movable cover is arranged under the convex ring; the water blocking pipe is inserted into the annular concave part to form the water trap while the annular concave part is closely matched with the grate into a whole, and the whole floor drain can be screwed out except the grate frame and the outer pipe. By means of the technical scheme, the floor drain is simple in structure, convenient to install and good in anti-reversing effect. Indoor environments are cleaner, the probability of insect transmitted disease spreading is reduced, and damage of sewer odor to human health is reduced.

Description

technical field [0001] The invention relates to the field of sewage pipelines, in particular to a ground drain. technical background [0002] Most of the floor drains currently used are single trap type or flap type, all of which have different defects: trap floor drains have poor anti-odor effect and cannot prevent reverse water, hard mechanical flap type floor drains cannot be closed hard Strict and easy to damage, the anti-adverse taste, anti-inverse water, and anti-pest effects are not ideal. Contents of the invention [0003] The purpose of this invention is to design a floor drain that can be unscrewed in one piece with a grate, a trap, and a movable cover. The invention has reasonable structure, time-saving installation, convenient cleaning, and is not easy to be damaged. Effect. [0004] The technical solution of the present invention is: a floor drain that can be unscrewed together with a grate, a water trap, and a movable cover, including: a grate frame, an ear...
