Vacuum adsorption device

Abstract

According to an embodiment of the present invention, a vacuum adsorption device is provided. The vacuum adsorption device includes: an adsorption part, a vacuum cavity is formed on the bottom surface for vacuum adsorption on the adherend surface, and a rotating support shaft protrudes from the top; an insertion hole for the rotation support shaft; and a rotation control part provided on the upper side of the main body, rotatable relative to the main body and the rotation support shaft, and protruding outward from the rotation support shaft At least one control shaft is formed, and the control shaft is raised or lowered by the rotation of the rotation control part, whereby a vacuum is formed or released in the suction part.

Description

technical field [0001] The present invention relates to a vacuum adsorption device, and more specifically, to a vacuum adsorption device that forms or releases a vacuum through a user's rotation action. Background technique [0002] Generally speaking, when storing and storing various items such as bathroom supplies, kitchen supplies, or simple indoor objects, other storage tools or hanging pieces are pasted on the wall or glass wool for storage and use. If it is an ordinary wall surface, it can be attached with nails, etc., but it cannot be used by the above-mentioned method on a tile or glass wall surface. [0003] Therefore, recently, an adsorption device for attaching and fixing articles to a wall surface by vacuum adsorption has been widely used. It can conveniently fix objects on the wall, etc., but the structure for forming a vacuum is complicated, or it cannot form a complete vacuum. [0004] For example, when creating a vacuum with a lever or tightening a screw, i...

Problems solved by technology

It can conveniently fix items on the wall, etc., but the structure used to form a vacuum is complicated, or it cannot form a complete vacuum

[0004] For example, when creating a vacuum with a lever or tightening a screw, it is difficult to grasp the sufficient tightening strength required to create a vacuum, so there is a problem that the helix of the lever or screw is worn out or that various parts such as the rotating body are damaged.

Moreover, the above-mentioned adsorption device using vacuum is composed of separate components such as a suction cup, a pressurization adjustment device, a cover, etc. After long-term use, the suction cup is separated or loosened. without breaking the vacuum

[0005] In addition, in the conventional products, when the rotation is locked, the suspension is separated from the suction device. Therefore, when placing objects, it is difficult to maintain balance due to the load acting on the suspension.

Therefore, the method of forming the hanging part on the central axis of the adsorption device is used, but the external force applied to the hanging part directly acts on the vacuum chamber of the adsorption device, and the adsorption function is reduced.
