Vacuum attachment device

Abstract

A vacuum attachment device is provided according to an embodiment of the present invention. The vacuum attachment device comprises: an attachment portion having a vacuum chamber formed on the bottom surface thereof such that the same is vacuum-attached to an attachment target surface and having a rotation support shaft formed to protrude from the upper surface thereof; a body portion coupled to the upper side of the attachment portion, an insertion hole being formed through the body portion such that the rotation support shaft is inserted therein; and a rotation control portion arranged on theupper side of the body portion such that the same can rotate with regard to the body portion and the rotation support shaft, wherein the rotation support shaft has at least one control shaft formed to protrude outward, and the control shaft can ascend or descend following a rotation of the rotation control portion and thereby form a vacuum in the attachment portion or remove the same therefrom.

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...

AI Technical Summary

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.
