First, the close contact member 100 is tightly fixed to the bottom of the sink, the fitting is fitted to the mounting groove (G) formed on the bottom surface of the sink on the upper surface of the tubular body 110 coupled to cover the upper portion of the support member 200. The protrusion 120 is integrally formed in a substantially cylindrical shape having a hollow.

A support flange 130 is formed between the upper portion of the tubular body 110 and the lower portion of the fitting protrusion 120 to enlarge the contact area with the bottom surface of the sink.

Here, of course, a plurality of screw holes for screwing with the sink along the edge of the support flange 130 may be formed in the form of grooves opened through holes or outwards.

In addition, the circumference of the fitting protrusion 120 is formed with a plurality of incision line 121 is formed to allow a flexible and elastic expansion when the mutual contact by the insertion of the female screw member 300, the outer peripheral surface formed on the bottom surface of the sink A plurality of wedge-shaped contact protrusions 123 are formed in the vertical direction or the horizontal direction to be elastically fitted in the mounting groove G.

And the hollow of the fitting protrusion 120 is formed narrower toward the bottom, the lower portion of the hollow is formed slightly larger with the same inner diameter as the upper, whereby the female screw member 300 is in close contact with the back member 100 during transportation The locking step 122 is naturally formed to prevent it from leaving freely.

Here, by forming the hollow cross section of the fitting protrusion 120 into an elliptical shape corresponding to the female screw member 300 when viewed in plan view from the central axis thereof, the rotational force according to the coupling of the support member 200 is applied to the female screw member 300. Even if it is transmitted, the female screw member 300 can be more stably prevented from slipping in the hollow of the fitting protrusion 120 due to close surface contact and interference such as frictional force.

In addition, in the above-described contents and the accompanying drawings, the locking jaw 122 is illustrated as being formed in the hollow lower portion of the fitting protrusion 120. However, since the female screw member 300 is once coupled, the locking jaw 122 is characterized in that it is not easily separated. For example, the same or similar functions may be provided, for example, the upper end of the fitting protrusion 120 may be formed of course.

At the lower inner side of the contact member 100, the male screw portion 210 of the support member 200 is inserted into the hollow of the fitting protrusion 120 and screwed together with the female screw member 300. In this state, when the support member 200 is rotated along the locking direction of the screw, as shown in FIG. 5B, the support member 200 rises to a certain height, and the upper surface thereof is in close contact with the bottom of the fitting protrusion 120. Then, as shown in FIG. 5C, the supporting member 200 does not rise any more due to contact interference, and the female screw member 300 naturally descends by screwing the male screw part 210. At this time, since the female screw member 300 having a wider width toward the upper portion expands the inner and outer diameters by the surface contact with the fitting protrusion 120 hollow, the fitting protrusion 120 closely adheres to the mounting groove G of the sink. Will be.

That is, since the inclined surface of the female screw member 300 is in close contact with the hollow of the fitting protrusion 120, the support member 200 is not easily rotated in the opposite direction without a strong external force, thereby maintaining a firmly fixed state. .

After that, by rotating the height adjustment member 400 in both directions it is possible to adjust the height according to the installation of the sink freely to level.

When the sink is transported and stacked, and the support member 200 is rotated in a direction opposite to the coupling direction with the female screw member 300, the coupling state is naturally released and can be easily separated.

In addition, since the stopper 220 formed on the outer circumferential surface of the support member 200 supports the gap between the leg and the cover plate P installed at the bottom of the sink, the cover plate P is pushed into the sink by the external force. It can be prevented.

In addition, when the upper portion of the holder (H) is provided with an elastic member (H2) that is elastically deformed when pressed, if a gap occurs between the holder (H) and the bottom of the sink by the design error or the environment of the installation place, the screen is compensated for (P) can maintain a more stable installation state.
