Sucker and vacuumizing lifting tool with same

Abstract

The invention discloses a sucker and a vacuumizing lifting tool with the same. According to the sucker and the vacuumizing lifting tool with the same, a cylindrical connecting body which protrudes outwards is arranged in the center of the sucker; a circle of sucker transformation groove sunken inwards the sucker is formed in the surface of the sucker with a connecting column as a center shaft; a paster outside release paper enables the sucker to be pre-adhered to the surface of an object; an adjusting bolt is rotated to pull the center of the sucker away from the surface of the object so that a vacuum space or a negative pressure space can be formed between the sucker and the object; when the vacuum space or the negative pressure space becomes larger and larger, an inward pulling force can be generated on the inner wall of the sucker, the pulling force is transmitted to the adjusting bolt through the connecting column, and then is transmitted to a pressure disc through the adjusting bolt so that the peripheral edge of the sucker and the periphery of the paster are tightly pressed to the surface of the object by the pressure disc, due to the fact that a double-sided adhesive tool for manufacturing the paster has a certain thickness, if the surface of the object is rough and not smooth enough, the double-sided adhesive tool can deform and fill the gap between the peripheral edge of the sucker and the surface of the object under the strong pressure from the pressure disc, and therefore the sucker and the vacuumizing lifting tool with the same can be applied to the rough surfaces of objects.

Description

technical field [0001] The invention relates to a vacuum suction cup capable of being adsorbed on the surface of a rough object, and belongs to the technology in the field of vacuum suction cups. Background technique [0002] Vacuum suction cups can be adsorbed on flat and smooth surfaces such as glass and ceramic tiles, so they are often made as tools for hanging or grabbing objects. [0003] Vacuum suction cups are generally made of plastic materials with certain rigidity and flexibility such as silicone rubber or PVC material, polyurethane or nitrile rubber or vinyl-containing polymers. The structure of most vacuum suction cups is a hollow cone, and the wall surface of the suction cup facing the surface of the adsorbent is a conical shape with the middle part sunken upward. The air inside is squeezed out, and then the suction cup is released, and the suction cup generates negative pressure in the tapered cavity of the suction cup during the self-resetting process, so tha...

Problems solved by technology

[0004] However, the surface of many objects is flat but not smooth enough, such as textured tiles, frosted glass and other objects. It is difficult for existing suction cups to suck on these rough objects.

Even if it is barely sucked, it will soon fall off the surface of the object due to air leakage
