Description

The device for opening and closing of the drain}

The present invention relates to a drain opening and closing device that can open and close the drain of the sink.

The wash basin to be drained after temporarily receiving water used is provided with a drain for discharging the water, the sink is provided with a drain opening and closing device for easy opening and closing of the drain.

In the conventional drain opening and closing device, the drain plug with the stem coupled to the center of the bottom is coupled to the upper and lower reciprocating movement in the drain of the sink, and the drain plug operation rod is movable up and down on one side of the upper surface of the sink. The bottom end of the drain plug operation rod and the stem of the drain plug are respectively coupled to both ends of the straight link bar.

Therefore, when the user presses the drain plug operation rod, one side of the link bar connected to the mouth stopper operation rod is lowered, while another side of the link bar connected to the stem is raised, thereby raising the stem above the sink. This can open the drain so that the water on the sink can drain down the drain.

On the other hand, in the conventional drain opening and closing device as described above, the stem has a cross wing is formed along the longitudinal direction of the stem so as not to shake inside the drain.

However, the cross-shaped wings formed in the longitudinal direction of the stem are formed to have a certain distance from the surface of the drain in consideration of friction with the drain. Thus, the stem may not be in perfect contact with the inner surface of the drain, and in some cases the stem may be distorted and not level with the drain. As such, if the stem is twisted out of parallel with the drain, the drain plug formed at the top of the stem is also twisted with the drain, which leads to a failure to seal the drain completely, eventually leading to a gap between the drain plug and the drain. Through the water can be discharged regardless of the user's intention.

In addition, the cross-shaped wings formed in the longitudinal direction of the stem, the water introduced into the drain is not able to rotate inside the drain, thereby, the water is not easy to discharge.

SUMMARY OF THE INVENTION An object of the present invention for solving the above problems is to provide a drain opening and closing device that allows a rod-shaped stem to move through a hole formed in the center of a support formed in the drain.

The present invention for achieving the above object, the drain pipe is inserted and detachably coupled to the drain; A support having at least two wings fixed to an inner circumferential surface of the drain pipe and having a hole formed at a center thereof where the wings meet; And a drain port stopper is formed at an end of the first side, and a second side is formed to move through the hole of the support, and a link bar connection part connected to a link bar connected to the drain stopper operating rod at the end of the second side. It includes a rod-shaped stem is formed.

The present invention has the effect of allowing the rod-shaped stem to move through the hole formed in the center of the support formed in the drain, thereby smoothing the flow of the fluid and allowing the fluid to be discharged more quickly.

In addition, the present invention has an effect that it is possible to facilitate the removal of foreign matter by allowing the drain plug formed on the end of the stem can be separated from the stem.

In addition, the present invention has the effect that by forming a screw thread on the inner peripheral surface of the drain opening and closing device, the fluid can be smoothly flowed out more quickly.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is an exemplary view schematically showing a state of use of the drain opening and closing device according to the present invention.

The drain opening and closing device according to the present invention, as shown in Figure 1, the drain pipe 130 is inserted into the drain of the sink 200 to form a passage for discharging water, at least two or more wings of the inner peripheral surface of the drain pipe It is fixed in the center of the wings meets the support 140 is formed in the hole and the end of the first side drain plug is formed, the second side is formed so as to move through the hole of the support, the second side The end of the rod includes a rod-shaped stem 120 is formed with a link bar connecting portion is connected to the link bar 160 connected to the drain plug operation rod 210.

On the other hand, one side of the upper surface of the sink 200, the drain plug operation rod 210 is penetrated to allow the up / down reciprocating movement, the lower end of the drain plug operation rod and the stem connected to the drain plug is a straight link bar 160 It is coupled to both ends.

That is, the link bar 160 penetrates through the drain pipe and is coupled to the stem, and both sides of the link bar are configured to move, and when the drain plug operation rod 210 is pressed, one side of the link bar coupled to the stem moves upward. As the drain plug 110 is moved upwards to open the drain hole D, and when the drain plug stopper working rod 210 is pulled upward, one side of the link bar coupled with the stem moves downward, the drain plug 110 ) Moves downward to block the drain.

2 is an exploded perspective view of the drain opening and closing device according to the present invention. 3 is a plan view of a drain pipe body applied to the drain opening and closing apparatus according to the present invention.

As described above, the drain opening and closing device according to the present invention includes a drain pipe body 130, a support body 140, and a stem 120.

The drain pipe 130 is inserted and detachably coupled to the drain of the sink, and the top surface of the drain pipe is disposed to form the same plane as the lower surface of the sink. On the other hand, the drain pipe may be composed of a single housing, it may be divided into a plurality of configurations for the convenience of manufacturing and assembly, in particular, as shown in Figure 2, the lower drain pipe 150 is manufactured separately It may be configured. However, in the following description, the drain pipe body 130 and the bottom drain pipe body 150 described above are collectively referred to simply as a drain pipe body, except that the lower drain pipe body 150 is to be described specifically. Here, the link bar insertion tube 151 is formed on the side of the lower end of the drain pipe body so that the link bar 160 is inserted and movable. In addition, a rotation ball 161 is connected to the outer circumferential surface of the link bar, and the link bar insertion pipe plug 162 performs a function of fixing the rotation ball to the link bar insertion pipe 151. That is, the rotating ball fixed to the link bar insertion tube by the link bar insertion tube stopper performs a function of preventing the fluid introduced into the drain pipe body from being discharged to the outside through the link bar insertion tube.

The support 140 is formed in the drain pipe to form a movement path of the stem, and may be formed in the middle of the open surface of the top of the drain pipe and the link bar insertion pipe among the inner surfaces of the drain pipe. The support may be formed so that two wings face each other as described above, and a groove may be formed in the center thereof to allow the stem to be inserted to move. However, the support may be composed of four wings 142 and a groove 141 formed at the center thereof, as shown in FIGS. 2 and 3, in order to be stably fixed to the inner circumferential surface of the drain pipe. On the other hand, the wing 142 may be directly connected to the inner circumferential surface of the drain pipe as described above or may be formed integrally with the drain pipe. In addition, the support may include a support frame (not shown) connecting the wings to each other, in this case, the support frame may be formed to correspond to the inner peripheral surface of the drain pipe, it may be mounted on the inner peripheral surface of the drain pipe. That is, the support 140 may be formed of a support frame, wings connected to the support frame, and a groove formed at the center of the wing. In this case, the support may be manufactured independently of the drain pipe and then mounted on the inner circumferential surface of the drain pipe.

The stem 120 moves up and down according to the movement of the link bar in the state of being inserted into the groove 141 of the support, and performs a function of opening and closing the drain hole by the drain plug formed on the top of the stem. Therefore, the thickness of the stem is preferably 0.05 to 0.1 mm smaller than the inner diameter of the groove 141. This error is smaller than the distance between the conventional stem and the drain pipe in which cross-shaped wings are formed in the longitudinal direction of the stem. On the other hand, the top of the stem may be formed as the drain plug as described above, where the drain plug may be made separately from the stem and then fastened to the top of the stem in the manner of bolts and nuts. Since the drain plug may be attached to or detached from the stem, the user using the present invention may remove the drain plug from the stem after the drain plug is removed from the stem when it is determined that foreign matter is caught in the drain pipe. Foreign material can be removed while checking. On the other hand, the fluid introduced into the drain pipe is rotated by the turning force (coriolis force), since the stem is configured in the shape of a rod, it can be discharged while rotating more smoothly, noise is also reduced. In addition, the body of the drain plug 110 may be divided into an upper portion, a middle portion, and a lower portion, among which, the middle portion 111 is formed in a shape recessed than the upper portion and the lower portion as the upper and lower portions. . The O-ring 170 formed of a material such as rubber may be inserted into the central part 111. That is, when the drain plug 110 is blocking the open inlet of the drain or drain pipe, the drain plug is in close contact with the inner peripheral surface of the drain or drain pipe by the O-ring 170, so that the water on the sink sinks the drain or drain pipe. Emissions can be prevented.

Figure 4 is a perspective view of the drain pipe to be applied to the drain opening and closing device according to the present invention, in particular showing the interior of the drain pipe.

As described above, in the present invention, since the stem is configured in the shape of a rod, when draining the water in the sink, the space between the stem and the drain pipe is widened for easy drainage, while the fluid flowing into the drain pipe rotates smoothly. Can be discharged faster.

On the other hand, in the present invention, in order to more smoothly discharge the fluid, as shown in Figure 4, the thread 131 is formed on the inner peripheral surface of the drain pipe. Here, the thread may be formed on all of the inner circumferential surface of the drain pipe, but may be formed only on the inner circumferential surface of the drain pipe of the lower portion of the support.

That is, even if there is no screw thread, the fluid will rotate by the turning force, etc., but the fluid is more smoothly rotated by the screw thread 131, thereby allowing the fluid to be discharged more quickly.

On the other hand, as shown in Figures 2 and 4, the through-shaped rectangular window is formed on the side of the drain pipe. The through-window is intended to allow the excess water from the sink to flow into the drain pipe and be discharged while the drain plug is blocking the drain. That is, although not shown in the drawings, there is a pipe connected to the through-window through the inside of the sink in the upper end of the sink, so that the overflowing water from the sink does not fall to the bottom of the bathroom flows into the drain pipe to be discharged.

Those skilled in the art will appreciate that various changes and modifications can be made without departing from the technical spirit of the present invention. Therefore, the technical scope of the present invention should not be limited to the contents described in the detailed description of the specification, but should be defined by the claims.
