Abstract

The utility model discloses an anti-leakage structure for a drain valve of a washing machine. The anti-leakage structure comprises a rubber member and grooves formed in the end part of a pipe, wherein a circle of flanges are arranged on the rubber member; the flanges of the rubber member are matched with the grooves in the end part of the pipe. According to the anti-leakage structure, the flanges of the rubber member are matched with the grooves in the end part of the pipe, the rubber member and the end part of the pipe are in surface contact with each other, and the contact surface is large, so that the water is unlikely to flow through, and the water-proof performance is effectively improved.

Description

A kind of water leak preventing structure of For Drain Valve of Washing Machine

Technical field

The utility model relates to a kind of water leak preventing structure of For Drain Valve of Washing Machine.

Background technology

See Fig. 1 and Fig. 2, the water leak preventing structure of existing For Drain Valve of Washing Machine is that the flange 4 by rubber parts 1 contacts to seal with the end of pipe 2, and because this contact is that line contacts with line, so contact area is little, and water resistance is poor.

Utility model content

Technical problem to be solved in the utility model is to provide the water leak preventing structure of the For Drain Valve of Washing Machine that a kind of water resistance is good.

In order to solve the problems of the technologies described above, technical scheme provided by the utility model is: a kind of water leak preventing structure of For Drain Valve of Washing Machine, comprise rubber parts, and the groove that is arranged on the end of pipe; Described rubber parts is provided with a circle flange; The groove fit of the flange of described rubber parts and the end of pipe.

The groove interference fit of the flange of described rubber parts and the end of pipe.

Adopted after technique scheme, the utlity model has following beneficial effect: the groove fit of the flange of (1) rubber parts of the present utility model and the end of pipe, making rubber parts and contacting of tube end is that face contacts with face, contact-making surface is large, make water be difficult for flowing through, effectively promoted water resistance.

(2) the groove interference fit of the flange of rubber parts of the present utility model and the end of pipe, this structure has further promoted water resistance of the present utility model.
