Abstract

The utility model relates to a floor drain which is composed of a U-shaped water drainage cup, an outer sealing ring for the cup, a water drainage grid port and an arced floating ball. The bottom of the water drainage barrier port is connected with a water drainage barrier bottom. The arced floating ball is installed between the water drainage barrier port and the water drainage barrier bottom and can moves upwards and downwards with definite distance. The lateral movement of the arced floating ball is limited into a smaller range by the lateral face of the water drainage barrier bottom. The floor drain has the advantages that the floor can effectively prevent underground gas from overflowing and can be easily disassembled and cleaned.

Description

Floor drain

The utility model relates to a kind of floor drain that mainly is made of u shape leaky cup, cup exterior seal ring, the grid mouth that leaks, circular arc ball float that is used for interior plumbing system.

The employed floor drain of daily life generally is made of u shape leaky cup, cup exterior seal ring, the grid mouth that leaks, circular arc ball float at present, its circular arc ball float directly is placed in the u shape leaky cup, in use be easy to generate deviation with being sealed and matched of grid mouth of leaking, thus the excessive effect of the influence underground gas of blocking-up.

The purpose of this utility model provides a kind ofly can block the excessive floor drain of underground gas better.

To achieve these goals, technical solution of the present utility model is such: at the bottom of the bottom of the grid mouth that leaks that has floor drain now is connected with the grid that leak, between the circular arc ball float is installed at the bottom of leak the grid mouth and the grid that leak, and can move up and down certain height, laterally moving by the side at the bottom of the grid that leak of circular arc ball float is limited in the small range.

Because between the circular arc ball float is installed at the bottom of leak the grid mouth and the grid that leak, it laterally moves the restriction of the side at the bottom of the grid that leaked, make when the circular arc ball float be subjected to buoyancy of water and when floating and being sealed and matched of grid mouth of leaking accurate to bit comparison, thereby it is excessive to block underground gas more effectively; The floor drain of this structure is because between the circular arc ball float was limited in leaking at the bottom of the grid mouth and the grid that leak, the three constituted a relatively-stationary integral body, becomes quite convenient when unpicking and washing floor drain in addition.

Below in conjunction with drawings and Examples the utility model is described in further detail:

Fig. 1 is the outline drawing of the utility model embodiment.

Fig. 2 is the structure sectional view of the utility model embodiment.

The outline drawing of Fig. 3 at the bottom of for the grid that leak among the utility model embodiment.

Fig. 4 is the upward view of Fig. 3.

Wherein: 1, cup exterior seal ring; 2, u shape leaky cup; 3, the grid mouth that leaks; 4, grid inner seal ring; 5, circular arc ball float; 6, leak at the bottom of the grid.

As shown in the figure, leak at the bottom of the grid 6 being provided with one below the grid mouth 3 that leaks, leak at the bottom of the grid 6 and the grid mouth 3 that leaks pass through thread connection, circular arc ball float 5 is arranged at the bottom of leak the grid mouth 3 and the grid that leak between 6, and can move up and down certain height, other have a grid inner seal ring 4 to be fixed on the bottom of the grid mouth 3 that leaks and be close to the grid that leak at the bottom of 6 inwall, by the grid mouth 3 that leaks, grid inner seal ring 4, circular arc ball float 5, leak at the bottom of the grid and 6 to connect the floor drain inner core the formed external screw thread by grid mouth 3 upper ends that leak is installed, be connected on the u shape leaky cup 2, the upper end wall of u shape leaky cup 2 is provided with glass exterior seal ring 1, more than constitutes a complete floor drain.Floor drain is installed in the upper port of sewer in use, cup exterior seal ring 1 cuts off the vent hole that goes out that sewer draws the floor drain periphery, and floor drain in use, total amassing has certain ponding in its u shape leaky cup 2, is subjected to buoyancy of water effect come-up and pressing grid inner seal ring 4 to reach blocking-up sewer and the excessive effect of underground gas thereby circular arc ball float 5 proportions are smaller.Because the utility model is provided with at the bottom of the grid that leak 6, to 5 position restrictions of circular arc ball float, make that being sealed and matched of circular arc ball float 5 and scupper 3 is accurate to bit comparison, sealing effectiveness is better, leaking at the bottom of the grid 6 also makes floor drain more convenient than in the past when folding is washed, and the utility model is provided with grid inner seal ring 4 and has further improved sealing effectiveness; 6 under the prerequisite constant to the limit function of circular arc ball float 5 at the bottom of the grid that leak of the present utility model, and its profile can be done different variations, itself and the connecting mode that also can adopt other that connects of the grid mouth 3 that leaks.
