Abstract

The utility model discloses an improved structure of a floor drain, which comprises a funnel-shaped drain body and a rotary filter plate; wherein, an upper port of the drain body is large; a lower port of the drain body is small; the rotary filter plate is arranged in the upper port of the drain body; and a check valve structure is arranged in the lower port. The utility model resolves the problem that dirty water can overflow the prior floor drain, and is characterized by simple structure, practicability and convenience.

Description

A kind of structure-improved of floor drain

Technical field

The utility model relates to the structure-improved of a kind of floor drain, particularly a kind of floor drain.

Background technology

Floor drain is widely used in the usefulness of the following water on ground such as rest room and kitchen, and present floor drain comprises all that generally leaking body forms with the filtration blade, wherein leaks body funneling structure, its upper port is bigger, the filtration chip select is being set above, and its lower port is less, directly is communicated with sewer pipe.The floor drain of this structure exists certain problem in the middle of reality is used, sewer pipe stop up or sewer pipe in during sewage backflow, sewage is easy to overflow from floor drain and pollutes ground.

The utility model content

The purpose of this utility model is to provide a kind of structure-improved of floor drain, and the sewage overflow problem that it can solve floor drain well has simple in structure, practical and convenient characteristics.

For achieving the above object, the utility model is by the following technical solutions:

A kind of structure-improved of floor drain comprises the leakage body of a funneling and filters blade that the upper port that wherein leaks body is bigger, and lower port is less, filters blade and is arranged on Lou on the body upper port, it is characterized in that: be provided with a check valve structure in the described lower port.

Above-mentioned check valve structure is made up of valve seat, helical pitch support, spool and dish spring, and wherein valve seat and helical pitch support engagement connection are coiled spring and be arranged between spool and the helical pitch support; Described helical pitch support afterbody is provided with a boss, is connected by a plurality of reinforcing ribs between boss and the rack body; The boss inner hollow, and the center is provided with a helical pitch track; Described spool is beveled structure, and the spool afterbody is built in the helical pitch track, and the spool head is holding on the seal washer that is being arranged in the valve seat endoporus under the effect of compact disk spring.

Above-mentioned valve seat lateral wall is provided with a round section joint ring.

Above-mentioned valve seat top is provided with a movable handle.

The utility model directly is provided with check valve structure leaking in the lower port of body, make the sewage can only be dirty and can not overflow, has stopped that sewage overflows and the phenomenon of polluting ground takes place from floor drain.

At this,, one round section joint ring is set at the valve seat lateral wall for guaranteeing check valve structure and the sealing of leaking the body lower port.

Moreover, clean for ease of the taking-up of check valve structure, be provided with a movable handle on valve seat top.

The specific embodiment

As illustrated in fig. 1 and 2, a kind of structure-improved of floor drain comprises the leakage body 1 of a funneling and filters blade 2 that the upper port 11 that wherein leaks body is bigger, and lower port 12 is less, and upper port 11 is being provided with filtration blade 2, and lower port 12 is provided with a check valve structure 3.

Described check valve structure 3 is made up of valve seat 31, helical pitch support 32, spool 33 and dish spring 34, and wherein valve seat 31 and helical pitch support 32 engagement connections are coiled spring 34 and are arranged between spool 33 and the helical pitch support 32.Described helical pitch support 32 afterbodys are provided with a boss 321, are connected by a plurality of reinforcing ribs 323 between boss 321 and the rack body 322; Boss 321 inner hollow, and the center is provided with a helical pitch track 3211; Described spool 33 is beveled structure, and spool 33 afterbodys are built in 3211 li on helical pitch track, and spool 33 heads are holding under the effect of compact disk spring 34 on the seal washer 35 that is being arranged in valve seat 31 endoporus.

The utility model directly is provided with check valve structure 3 for 12 li at the lower port that leaks body 1, make the sewage can only be dirty and can not overflow, has stopped that sewage overflows and the phenomenon of polluting ground takes place from floor drain.

At this,, one round section joint ring 4 is set at valve seat 31 lateral walls for guaranteeing check valve structure 3 and the sealing of leaking body lower port 12.

Moreover, clean for ease of the taking-up of check valve structure 3, be provided with a movable handle 36 on valve seat top.
