WIPO Patent Application WO/2021/075823
Kind Code:
A1
Abstract:
A disclosed suction plate according to the present invention comprises: a suction unit formed of a soft material and having a bottom surface as a suction surface and an extension shaft at the center of the upper surface thereof; a body unit formed of a hard material and provided to cover the suction unit while the extension shaft passes through the center portion thereof, the body unit having an adhesion reinforcing portion attached along the bottom-surface edge thereof so as to be placed along the upper-surface edge of the suction unit; a pulling unit coupled to a penetrating end of the extension shaft and pulling the extension shaft while being rotated, such that the suction surface of the suction unit is adsorbed to a fixed surface; and an elastic unit provided to surround the extension shaft located between the facing surfaces of the body unit and the pulling unit to pressurize the body unit toward the suction unit by elastic force. The elastic force of the elastic unit continuously pressurizes the body unit and enables the edge of the body unit to push the edge of the suction unit, and thus, a vacuum state between the suction unit and an installation surface can be maintained. According to the present invention, the elastic force of the elastic unit continuously pressurizes the body unit and enables the edge of the body unit to push the edge of the suction unit, and thus there is the effect of maintaining a vacuum state between the suction unit and an installation surface for a long time period.
