The present invention relates to an opening / closing device installed in a drainage port of a washstand to close the drainage port to hold tap water filled in a fresh water portion of a washstand or to open the drainage port to drain tap water. More particularly, The present invention relates to a one-touch opening / closing apparatus for a sink for a wash basin,

Among various techniques related to opening and closing apparatus for a wash basin drain,

Korea Utility Model Registration No. 20-0461793 (Registered July 31, 2012, referred to as "Prior Art") "One-touch drain valve for wash basin"

The prior art is provided with a fixed shaft having a longitudinal groove on one side and a movable shaft tube inserted from the top of the fixed shaft and provided so as to move up and down so that the end of the tightening bolt is positioned on the groove. And the valve cap is provided in a state of being assembled with a screw.

In the interior of the movable shaft tube, a spring, a hook, and an operating plate having operating grooves are formed so that the valve cap can open and close the drain port in a one-touch manner at a drain port. Therefore, when the user presses the valve cap once, the valve cap closes the drain port, and when the valve cap closing the drain port is pressed again, the valve cap opens the drain port. And a drain member having a screw hole coupled to the lower end bolt portion of the fixed shaft and having a vertical drain hole extending from the lower portion to the upper portion of the outer surface and having a vertically extending blade portion formed outwardly in four directions toward the outside .

As shown in the drawings, the drain valve (corresponding to the open / close module of the present invention) includes a drain member having a cross shape when viewed in a plan view, at a lower end portion thereof, And is supported by the inner wall,

Since the drain valve is not in a form to be coupled to the inner wall of the drain hole but is merely a stationary shape, in the course of filling the fresh water portion of the wash basin with tap water or draining tap water, the drain valve is moved up and down by water pressure, It can be shaken by force or force.

That is, there is a problem that the function of the drain valve for sealing the drain hole is deteriorated due to repetitive flow.

In order to solve the above problems, as shown in FIG. 6, an opening / closing device is disclosed in which the drain valve and the drain pipe are not easily separated by the flow of tap water.

As can be seen from Fig. 6, the mounting groove 4 is formed upward at the lower end of the drainage member 3. As shown in Fig.

A coupling portion 5 is formed to protrude from the inner peripheral surface of the drain hole 1a.

When the drainage member 3 descends along the drain port 1a, the lower end of the drainage member 3 comes into contact with the connection portion 5.

When the drain member 3 is rotated to the left or right, the mounting groove 4 corresponds to the engaging portion 5. [

At this time, the drain member 3 is lowered to move the coupling part 5 to the upper end of the entrance part 4a, and then the drain member 3 is rotated leftward or rightward to connect the coupling part 5 to the engagement part 4b. As shown in Fig.

According to this, the drain member 3 is fixed by the mounting groove 4 and the engaging portion 5 to prevent the drain valve from flowing in the drain hole.

However, in such a case, it is difficult to take out the drainage member manufactured after the injection molding from the mold, because the mold or core must enter the mounting groove recessed inward of the drainage member during injection molding for producing the drainage member.

It is an object of the present invention to provide an opening and closing apparatus having a drainage member which is designed not to be easily separated by the flow of tap water and to be easily taken out from a mold after injection molding.

According to an aspect of the present invention, there is provided a one-touch opening / closing apparatus for a sink for a sink,

A drain pipe installed in the washstand, the drain pipe having a drain hole penetrating through the inside thereof;

The water pipe is inserted into a drain hole of the drain pipe,
