When the valve member 300 includes the packing 330 as in the second embodiment, by performing the functions of the rod 310 and the head 320 by using a ready bolt, 300 can be easily provided.

The push member 400 is disposed on the upper side of the post 120 and is coupled to the upper end of the rod 310 of the valve member 300 to move up and down together with the valve member 300.

The push member 400 is in the form of a cap having a dome shape on an upper surface thereof. When the valve member 300 is lowered, the push member 400 is lowered to be in contact with the upper surface of the post 120.

The push member 400 may be coupled to the rod 310 in various manners such as screwing, interference fit, adhesive bonding, etc., depending on the structure of the valve member 300.

The compression spring 500 is formed of a known coil spring and is fitted to the outside of the post 120 and is interposed between the holder 200 and the push member 400 to press the push member 400 and the valve member 300 .

The cover 600 is coupled to the upper portion of the holder 200,

An insertion space portion 610 formed vertically through the center; And

And a corresponding engaging portion 620 protruding from the lower portion and fastened to the engaging portion 220 of the holder 200.

The insertion space 610 has a structure corresponding to the circumference of the push member 400, thereby providing a space for the push member 400 to enter when the push member 400 is lowered.

The corresponding engaging portion 620 is formed in a cylindrical shape and is fitted into the engaging portion 220 of the holder 200. A corresponding helical portion 621 to be fastened to the helical portion 221 of the engaging portion 220 is formed on the inner circumferential surface thereof do.

The hook member 700 is for supporting various articles and is fixed between the holder 200 and the cover 600 by mounting the cover 600 on the holder 200. [

According to the illustrated embodiment, the hook member 700 is annular and is fitted between the cover 600 and the holder 200. Although not shown, the hook member 700 may be formed with a ring, a rod, or a holder for holding a towel or the like.

The hooking member 700 may be fitted to the engaging portion 220 of the holder 200 and press-fitted by the corresponding engaging portion 620 of the cover 600 as shown in FIGS. 1 to 4 A separate mounting portion 240 is fixed to the upper portion of the holder 200 and the lower end of the hooking member 700 is fixed to the upper portion of the holder 200 as shown in FIGS. 5 'to 8' The edge can be fixed by pressing the upper surface of the hooking member 700. [

Hereinafter, an installation process of the adsorption unit according to the embodiment of the present invention will be described.

First, as shown in FIG. 1 and FIG. 5, when the push member 400 is disposed in contact with the upper surface of the post 120 in a state in which the lower surface of the attracting plate 110 is disposed to face the installation target surface 10, The compression spring 500 is compressed and deformed as shown in FIGS. 2 and 6, so that the push member 400 and the valve member 300 are separated from each other And the vent hole 123 of the post 120 is opened.

Then, when the push member 400 is further pressed (hereinafter referred to as "final press") so that the post 120 in contact with the push member 400 is lowered, as shown in FIGS. 3 and 7 The adsorption plate 110 is elastically deformed in a flat shape and is brought into close contact with the installation target surface 10. At this time, the air between the suction plate 110 and the installation target surface 10 can be easily discharged through the vent hole 123 through the head 320 of the valve member 300.

When the pressure applied to the push member 400 is released, the compression spring 500 is compressed and deformed as shown in FIGS. 4 and 8 so that the push member 400 and the valve member The vacuum is generated between the suction plate 110 and the installation target surface 10 by the resilient restoring force of the suction plate 110 so that the suction port 100 is moved to the installation target Can be strongly adsorbed to the surface (10).

As a result, according to the suction unit according to the embodiment of the present invention, when the push member 400 is initially pressed, the vent hole 123 of the post 120 is opened, and in this state, The air between the adsorption plate 110 and the installation target surface 10 is discharged through the vent hole 123 when the adsorption plate 110 is brought into close contact with the installation target surface 10 so that the adsorption unit can be easily Can be installed.

In addition, when the adsorption force decreases as time elapses after the installation of the adsorption unit, the user can easily recover the reduced adsorption force only by pushing the push member 400 one-touch.

As shown in the figure, the push member 400 is exposed to the upper side of the cover 600 in a state in which the post 120 is lifted, and the insertion space portion of the cover 600 610) is formed.

The identification part 410 may be made of a complementary color of the color of the push member 400 and the cover 600, or may be made of other conspicuous colors.

As a result, the identification member 410 is exposed to the upper side of the cover 600 when the post 120 is lifted due to the lowering of the adsorption force of the adsorption orifice 100, thereby allowing the user to lower the adsorption force of the adsorption orifice 100 So that it can be visually confirmed easily.

While the present invention has been described with reference to the accompanying drawings, it is to be understood that the present invention is not limited to the exemplary embodiments described above, and various changes and modifications may be made by those skilled in the art. And should be construed as falling within the scope of protection of the invention.
