Circular two-sided suction cup for protecting ancient and valuable vase

Abstract

The invention discloses a circular two-sided suction cup for protecting an ancient and valuable vase. The circular two-sided suction cup is characterized in that silica gel suction cups are arranged on the circle centers of the lower end face and the upper end face of a circular suction cup seat respectively, 2-10 circles of silica gel suction cups are arranged on the lower end face and the upper end face in the radial direction, the number of the silica gel suction cups which are evenly distributed on the outer ring is larger than that of the silica gel suction cups which are evenly distributed on the inner ring, and all the silica gel suction cups can eliminate the adsorption force easily simultaneously; the hole bottoms of sucking holes of the silica gel suction cups on the lower end face and the upper end face of the suction cup seat are communicated with lower air holes and upper air holes which are formed in the lower part and the upper part in board thickness of the suction cup seat in the horizontal direction through vertical inlet / vent holes respectively; left one-way inlet / outlet valves and right one-way inlet / outlet valves are arranged in the left inlet / vent holes and the right inlet / vent holes formed in the tail ends of the left end and the right end of linear air holes of the lower air holes and the upper air holes respectively. According to the circular two-sided suction cup for protecting the ancient and valuable vase, the ancient and valuable vase can be firmly adsorbed and can be taken down easily and completely to conduct cleaning or collecting or transferring, antiques and valuable vases are effectively protected, losses are reduced, and use is convenient.

Description

technical field [0001] The invention relates to the technical field of double-sided suction cups, in particular to a circular double-sided suction cup for protecting ancient and precious vases. Background technique [0002] The existing national treasure cultural relic vases are all ancient vases hundreds of years ago, which are rare in the world and cannot be recreated. The national treasure cultural relic vases are all directly placed in the collection cabinets of the National Cultural Relics Museum or provincial and municipal cultural relics museums; Old vases or newly purchased precious vases are also placed directly on the vase rack or on the desk or on the ground. Since the vase is a hollow body made of ceramic sintering, the bottom of the bottle is small and the placement stability is poor. It is very easy to overturn and smash during an earthquake, causing great losses. [0003] The existing double-sided suction cup can adsorb small objects with a plane on the wall,...

Problems solved by technology

[0002] The existing national treasure cultural relic vases are all ancient vases hundreds of years ago, which are rare in the world and cannot be recreated. The national treasure cultural relic vases are all directly placed in the collection cabinets of the National Cultural Relics Museum or provincial and municipal cultural relics museums; Old vases or newly purchased precious vases are also placed directly on the vase rack or on the desk or on the ground. Since the vase is a hollow body made of ceramic sintering, the bottom of the bottle is small and the placement stability is poor. It is easy to overturn and smash during an earthquake, causing great losses

[0003] 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. Pull the small objects from the double-sided suction cups with force, either the double-sided suction cups will be damaged or the small objects will be damaged, resulting in economic losses

Existing double-sided suction cups cannot be used to protect ancient and valuable vases
