The upper inclined surface of the first protruding protrusion 13 contacts the lower inclined surface of the second gear portion 31 to rotate the rotary gear 30 so that the rotary gear 30 is slidably inserted into the guide rail 14, 2 protruding jaws 15 as shown in Fig.

That is, when the rotary gear 30 is slidably inserted into the guide rail 14, the water-stop 50 is opened, and when the second projection 15 is engaged, the water-stop 50 is closed.

2 to 3 and 5, the first gear portion 21 is formed on the upper surface of the up-and-down moving gear 20, and the insertion groove 23 is formed on the inner side of the upper portion. And a third screw thread 22 is formed on the outer circumferential surface and inserted into the body 10.

The fitting projection 33 of the rotary gear 30 is inserted into the insertion groove 23 of the moving gear 20 so that the first gear portion 21 and the second gear portion 31 are engaged with each other.

The up and down gear 20 moves the rotary gear 30 up and down to move the guide rail 14 to the second protruding step 15 or to move the second protruding step 15 to the guide rail 14 .

The first gear portion 21 is slid on the guide rail 14 without being influenced by the second protruding jaws 15 so as to move up and down and to be caught by the lower stopping jaw 16, Respectively.

The third thread 22 is fastened to the fourth thread 62 formed on the inner circumferential surface of the vortex generator 60.

2 to 3 and 5, the rotary gear 30 of the main component is formed with a second gear portion 31 which is engaged with the first gear portion 21 of the up-and-down moving gear 20 And a second insertion groove 32 is formed in the upper portion.

At this time, the second insertion groove 32 may be tapered so as to become narrower toward the lower side.

The second gear portion 31 is formed to protrude from the outer circumferential surface of the rotary gear 30 and a lower inclined surface is formed at the lower portion.

The upper inclined surface of the first protruding protrusion 13 contacts the lower inclined surface of the second gear portion 31 to rotate the rotary gear 30 so that the rotary gear 30 is slidably inserted into the guide rail 14 Or the second protruding jaw (15).

Further, an elastic member 40 is inserted into the second insertion groove 32.

3 to 5, the lower portion of the elastic member 40 is inserted into the second insertion groove 32 and the upper portion of the elastic member 40 is inserted into the third insertion groove 53 formed at the lower portion of the water- ).

At this time, as shown in the drawing, the elastic member 40 is formed to be narrowly tapered from the upper portion to the lower portion, thereby realizing the effect that the elastic member 40 can exert the elastic force stably when the water- do.

Here, the upper portion of the elastic member 40 may be fitted into the third insertion groove 53 of the water-stopper 50. This is to prevent the elastic member 40 from being idle.

In other words, the shape of the elastic member 40 is narrowly tapered from the upper portion to the lower portion, and the upper portion is inserted into the third insertion groove 53 formed in the lower portion of the water- 2 insertion grooves 32, respectively.

That is, the conventional elastic member 40 'is formed in a cylindrical shape having the same outer circumference, and the upper part is inserted into the third insertion groove formed in the lower portion of the water-stopper 50. When the water- Since the elastic member 40 'is formed to have a size larger than the outer circumferential size of the elastic member 40', the elastic member 40 'can not stably exhibit the elastic force, resulting in a loose phenomenon, . At this time, even if the size of the third insertion groove 53 of the water-stopper 50 is made equal to the outer circumferential size of the elastic member 40 ', the elastic member 40' bends outward and can not be stably compressed, It is not preferable to reduce the size of the third insertion groove 53 formed in the lower portion of the water-stopper 50. [

As a result, there is a problem that the elastic member flows in the third insertion groove 53 and can not stably exhibit the elastic force, resulting in malfunction and failure, and the opening / closing device inserted into the drain hole is shaken, . More specifically, the lower part of the elastic member 40 is inserted into the second insertion groove 32, the upper part is inserted into the third insertion groove 53 formed at the lower part of the waterproof plug 50, By having the serpentine feature, the spring is fitted to the upper part and the lower part so as to prevent the shaking and the loosening.

2 to 3 and 5, the rubber plug 51 is inserted into the outer circumferential surface of the main component 50 and the third insertion groove 50 is formed in the lower portion of the elastic member 40, And a first thread 52 is formed on the inner circumferential surface of the body 10 so as to correspond to the second thread 11,

That is, the up-and-down moving gear 20 is inserted into the body 10 and the fitting protrusion 33 of the rotary gear 30 is inserted into the first insertion portion of the up-and-down moving gear 20, The elastic member 40 is inserted into the second insertion groove 32 of the body 10 and the second thread 11 of the body 10 and the inner wall of the water- 1 threads 52 are engaged with each other and are elastically supported by the elastic force of the elastic member 40.

2 to 3 and 5, the vortex generator 60 in the main constituent elements is formed such that the protruding piece 61 is inclined from the upper part to the lower part on the outer circumferential surface, A fourth thread 62 is formed in correspondence with the third thread 22 to be fastened to the lower portion of the body 10.

The shape of the protrusion 61 may be inclined from the bottom to the top, but it is most preferable that the protrusion 61 is inclined from the top to the bottom.

In addition, the vortex generator 60 protrudes upward to realize the effect that the one-touch drain port opening / closing device can be stably installed on the inner surface of the drain port as compared with the conventional vortex generator 60 '.

In detail, when a conventional drainage port is provided with a drainage opening / closing device so that the size of the drainage opening / closing device can be set to be standardized and a conventional opening / closing device equipped with the vortex generator 60 'is installed, the lower part of the opening / Since the opening and closing device is heavily flowed due to the small area contacted by the operation, frequent failure occurs. However,

Since the vortex generator 60 of the present invention increases the area of the vortex generator 60 that is in contact with the inner surface of the drain port by the protrusion 63 protruding upwardly, the one-touch drain port opening / closing device flows less and the failure occurrence rate can be reduced, It is preferable that the tapered surface 64 is provided on the inner side surface of the body 10 so that the vortex generator 60 is not caught in the lower portion of the body 10 so that the operation can be smoothly performed .

The vortex generator 60 has a protruding portion 63 protruding from the upper portion of the protruding piece 61 formed on the outer circumferential surface and the protruding portion 63 has a tapered surface 64 on the side of the body 10, .

The protrusions formed on the outer circumferential surface of the conventional vortex generator are not provided with protrusions having tapered surfaces, so that the vortex generators flow from the standardized drain port, thereby causing frequent failures. To solve this problem, (64). It is not difficult to form only the projecting portion 63. However, when the projecting portion 63 is formed, the foreign material is caught by the vortex generator 60, The protrusion 63 is formed in the upper direction so that the foreign matter drained to the outside of the body 10 can be drained without being affected by the protrusion 63. [

That is, if the protrusion 63 is formed in the lower direction, the water and foreign matter generated by the eddy current generator 60 may be caught by the protrusion 63 formed in the downward direction, The projecting portion 63 and the tapered surface 64 are formed so as not to form the protruding portion 63 to increase only the area of the protruding portion 63. The protruding portion 63 and the tapered surface 64 are formed, This is to solve the problem that the drain can be clogged.

The protruding portion 63 is provided with a tapered surface 64 on the side of the body 10 in order to smoothly discharge foreign matter as well as the operation of the vortex generator 60 by the body 10.

In addition, the vortex generator 60 is fixed to the washstand by hanging on the jaw 100 formed on the inner peripheral surface of the drain trap.

The protrusions 61 are formed on the outer circumferential surface of the vortex generator 60 such that the protrusions 61 are sloped from the top to the bottom and the protrusions 63 protruding upward are formed, And a tapered surface 64 is provided on a side surface of the body 10 so that the vortex generator 60 can be smoothly operated without being blocked. As a result, the area contacted with the inner surface of the drain hole is increased, so that the one-touch drain hole opening / closing device is fixed without being shaken, so that the operation is smoothly performed. In addition, the problem of failure occurrence and water drainage can not be smoothly solved .

It is not difficult to form the protrusion 63 only on the protrusion 61. However, when the protrusion 63 is formed, foreign matter may be caught by the vortex generator 60, The present applicant has formed the protruding portion 63 in the upward direction rather than the downward direction so that the foreign matter drained to the outside of the body 10 can be drained without being affected by the protruding portion 63. [

That is, if the protrusion 63 is formed in the downward direction, water and foreign matter generated by the vortex generator 60 may be caught by the protrusion 63 formed in the downward direction, and the drain hole may be clogged.

The protruding portion 63 is provided with a tapered surface 64 on the side of the body 10 in order to smoothly discharge the foreign matter as well as the operation of the vortex generator 60 by the body 10. [

6, when the upper part of the drain trap is closed by the water stopper 50 as shown in FIG. 6 to collect water and then the water is drained by opening the water stop 50, the water stop 50 The upper and lower moving gears 20 are slid to the guide rails 14 of the body 10 and move upward.

Therefore, the up-and-down moving gear 20 moves the rotating gear 30 hooked on the second protruding jaw 15 upward.

The rotating gear 30 and the up-and-down moving gear 20 are moved downward by the elastic force of the elastic member 40 and the lower and upper inclined surfaces of the rotating gear 30, The lower inclined surface slides on the upper inclined surface of the formed first protruding protrusion 13 so that the rotary gear 30 rotates and slides on the guide rail 14 to move downward.

The rotary gear 30 sliding on the guide rail 14 moves the up and down moving gear 20 downward by the elastic force of the elastic member 40 and the body 10 and the water- So that the drain port is opened.

The operation of closing the opened water-stopper 50 is as follows. When the water-stopper 50 and the body 10 are moved downward by pressing the water-stopper 50 as shown in FIG. 6 and the guide rail 14 of the body 10 is moved downward, So that the vertically-moving gear 20 is moved upward.

Accordingly, the up-and-down moving gear 20 moves the rotary gear 30 slidably on the guide rail 14 upward.

The rotating gear 30 and the up-and-down moving gear 20 are moved downward by the elastic force of the elastic member 40 and the lower and upper inclined surfaces of the rotating gear 30, The lower inclined surface slides on the upper inclined surface of the formed first protruding jaw 13 to rotate the rotary gear 30 and is caught and fixed to the second protruding jaws 15.

Therefore, the body 10 and the water-stopper 50 are moved downward and the drain port is closed.

The present invention of opening and closing the drain port by one-touch as described above can reduce the manufacturing cost by reducing the number of the main components of the product and the number of processing steps.

In addition, the raw material of the product is changed from metal to plastic, so that the cost reduction effect can be obtained.

In addition, when maintenance is required due to breakage or breakdown of major components, the user can directly repair it, and the effect that can be used semi-permanently can be obtained.

Further, due to the vortex generator fastened to the lower part, vortex is generated at the time of drainage, so that the drainage speed of the water is increased and the foreign matter is prevented from being settled.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
