Square two-face suction cup capable of easily eliminating sucking force

Abstract

The invention discloses a square two-face suction cup capable of easily eliminating sucking force. The square two-face suction cup is mainly characterized in that the lower end face and the upper end face of a square suction cup base are each provided with silica gel suction cups which are evenly arranged in order and can easily eliminate sucking force. The hole bottoms of suction holes in the silica gel suction cups on the lower end face and the upper end face of the suction cup base are communicated with lower and upper-layer air holes formed in the lower and upper portions in the plate thickness of the suction cup base in the horizontal direction through perpendicular air inlet/outlet holes. The tail ends of the left and right ends of the transverse air hole of the lower and upper-layer air holes are provided with a left air inlet/outlet hole and a right air inlet/outlet hole. Left and right one-way air inlet/outlet valves are arranged in the left and right air inlet/outlet holes and thread holes. The square two-face suction cup can firmly suck objects with planes and can also easily eliminate sucking force, the sucked object can be easily and completely taken down, use is convenient, economic losses are reduced, the using function is improved, and the cultural relic is effectively protected.

Description

technical field [0001] The invention relates to the technical field of double-sided suction cups, in particular to a square double-sided suction cup that can easily eliminate adsorption force. Background technique [0002] The existing double-sided suction cup can adsorb small objects with a plane on the wall, mainly because the suction cup is compressed and opened under the action of an external force, and the negative pressure formed during the reset process after the external force disappears and the atmospheric pressure in the air form a certain degree. The small object with flat surface is firmly adsorbed on the double-sided suction cup, but it is very difficult to remove the small object from the double-sided suction cup. People often rely on grasping the small object with their hands. Pulling the small object from the double-sided suction cup with force, either the double-sided suction cup will be damaged or the small object will be damaged, resulting in economic loss...
