Abstract

The present invention relates to a vacuum triple-structure suction plate, and more particularly, to a vacuum triple-structure suction plate that is detachably attached to the walls in a bathroom or a kitchen by vacuum pressure and has a suction plate 110 recessed downward so that when the suction plate 110 is pulled up to be sucked by vacuum, the bottom is brought in close contact with a surface from the middle portion into a vacuum state and is then completely brought in close contact with the surface by stress in the body 300.

Claims

1. A vacuum triple-structure suction plate comprising:

a suction unit 100 that includes a suction plate 110 being elastically transformable and having a protrusion 111 on the bottom, a suction diaphragm 120 having a fastening hole 121 at the center so that the protrusion 111 of the suction plate 110 is fitted in the fastening hole 121, and a bolt 130 having a thread on the outer side and coupled to the top of the suction plate 110;

an auxiliary vacuum diaphragm 200 having a seat to place the suction plate 110 therein and having an auxiliary vacuum hole 210 at a center thereof through which the bolt 130 is inserted;

a body 300 having a seat on a bottom thereof, in which the auxiliary vacuum diaphragm 200 is seated, and having a body hole 330 at a center thereof through which the bolt 130 is inserted;

a washer coupled to a top of the body 300 and having a washer hole 420 at a center thereof through which the bolt 130 is inserted; and

a rotary cap 500 disposed on the washer and having a thread groove 510 having a thread on an inner side thereof to be coupled to the bolt 130,

wherein the body 300 has body protrusions 320 with predetermined intervals around the body hole 330, a boss 530 is formed inside the rotary cap 500, a bolt groove 510 is formed in the boss 530, and bottom grooves 520 are formed with predetermined intervals on the outer side of the boss 530, so that the body 300 is rotated at predetermined angles and locked by the combination of the body protrusion 320 and the bottom grooves 520.

2. The vacuum triple-structure suction plate as claimed in claim 1, wherein the body protrusion 320 of the body 300 is partially cut so that the rotary cap 500 can be smoothly rotated.
