Abstract

The utility model relates to a floor drain which comprises the following components: a cylindrical filtering device, a pull bar, a filtering net and a main water pipe. The edge of a top opening of the cylindrical filtering device is provided with an annular flange which radially extends outwards. The annular flange is provided with at least two snap boards which correspond with each other in the radial direction. A channel section is formed between the snap boards and the annular flange. The edge of the top end of the main water pipe is provided with an annular bottom wall which radially extends outwards. The edge of the annular bottom wall is provided with an annular circumferential wall which radially extends upwards. The top edge of the annular circumferential wall is provided with an annular projected wall which radially extends outwards. The annular projected wall is provided with grooves at positions which correspond with the snap boards on the annular flange in a longitudinal direction. The main water pipe is in overlap jointing with the annular flange through the annular projected wall. Furthermore the annular projected wall is partially screwed into the channel section through rotating the main water pipe, thereby forming snap jointing between the main water pipe and the cylindrical filtering device. The floor drain further has the following advantages: convenient detachment, and high practicability.

Description

A kind of floor drain

Technical field

The utility model relates to the kitchen guarding of family construction drainage technical field, is specifically related to a kind of floor drain.

Background technology

Those skilled in the art should know, floor drain of the prior art generally comprises the filter with transfer window, be sleeved on the main flow water pipe of filter inner chamber and the screen pack that is arranged on port, main flow water pipe top, in actual use, water enters the main flow water pipe and flows to filter via screen pack, then after filtering by filter, the rubbish such as dust are stayed in filter, water flows out via transfer window, yet the floor drain of this structure exists following defect: because filter is arranged under earth's surface, when the dust and other impurities in filtering device piles with the filter inner chamber, the user often is difficult to filter is extracted and cleaned, cause great inconvenience.

Summary of the invention

The purpose of this utility model is to overcome the defect of prior art, and a kind of simple in structure, easy accessibility, practical floor drain are provided.

For achieving the above object, the utility model adopts a kind of floor drain, comprise the tubular filter, the main flow water pipe of the opening-like state of pull bar and screen pack and two ends, offer transfer window on the circumferential wall of wherein said tubular filter, and the bottom of this tubular filter is closed state, top is open state, described main flow water pipe sleeve is contained in described tubular filter, and form the overflow gap between this main flow water pipe and described tubular filter, described screen pack is arranged on the top port of described main flow water pipe, the top end opening edge of described tubular filter has the annular flange flange extended radially outwardly, there are at least two on this annular flange flange at corresponding in the radial direction clamp, form draw-in groove between described clamp and described annular flange flange, the edge, top of described main flow water pipe has the annular bottom wall extended radially outwardly, the edge of this annular bottom wall has axial upwardly extending annular perisporium, form between described annular bottom wall and described annular perisporium and expand chamber, described screen pack fits in described expansion chamber, the tip edge of described annular perisporium has the convex annular wall extended radially outwardly, corresponding position offer fluting in a longitudinal direction with clamp on described annular flange flange on this convex annular wall, the inner side edge of described fluting vertically extends upward assembly wall along having, offer installing hole on described assembly wall, the two ends of described pull bar are installed respectively into described installing hole and then are formed articulating between pull bar and described assembly wall, described main flow water pipe forms overlap joint by the annular flange flange of convex annular wall and described tubular filter, and further by rotating the main flow water pipe, make described convex annular wall precession draw-in groove partly, and then the clamping of formation main flow water pipe and described tubular filter.

Concrete, described tubular filter forms rigid structures by deep-drawing technique.

The utility model is by the above-mentioned improvement to prior art, due to main flow water pipe and tubular filter are connected together, when the dust and other impurities in the tubular filter is too much, the user can extract main flow water pipe and tubular filter by pull bar easily, and rotation main flow water pipe makes it to separate with the tubular filter, to facilitate the user to clean the foreign material in the tubular filter, in sum, obviously visible floor drain of the present utility model is for the user, for reaching convenient purpose of cleaning, dismounting characteristics have easily been shown greatly, and improved the practicality of floor drain, secondly, because the tubular filter in the utility model forms rigid structures by deep-drawing technique, effectively improved the bulk strength of tubular filter, non-deformability is better.
