Problems solved by technology

Since this type of suction cup relies on its own deformation or suction to generate suction, the inner wall and surrounding edges of the suction cup will be displaced during use and will continue to receive an inward pulling force, causing the surrounding edges of the suction cup to move inward, which is prone to air leakage The phenomenon will affect the function of the suction cup

Embodiment Construction

[0020] Such as Figure 1 to Figure 7 As shown, a kind of suction sucker mainly includes sucker 1, pressure plate 2, the pressure plate is pressed on the edge around the sucker, the sucker is a plane that can be stretched and deformed under the action of external force, and there is an upward protrusion on the top of the pressure plate. Air nozzle 21, the air pump sucks out the air in the pressure plate through the air nozzle, generating negative pressure between the inner wall of the pressure plate and the suction cup, deforming the middle part of the suction cup toward the pressure plate, and forming a vacuum between the suction cup and the surface of the object Space, so that the suction cup is sucked tightly on the surface of the object. Due to the negative pressure formed in the inner hole of the pressure plate, a pulling force is generated on the pressure plate towards the suction cup, so that the pressure plate can press the suction cup on the surface of the object.

Abstract

An air suction cup mainly comprises a suction cup body and a pressure plate. The pressure plate is pressed on the edge of the periphery of the suction cup body. The suction cup body is a plane capable of being stretched to deform under the action of external force. An outwards-protruding air nozzle is arranged at the top of the pressure plate. The suction cup body is pressed on the surface of an object through the pressure plate, then air between the pressure plate and the suction cup body is extracted by an air pump through the air nozzle, vacuum space is formed between the pressure plate and the suction cup body, and therefore the suction cup body is pulled to deform in the direction of the pressure plate; and vacuum space is also formed between the suction cup body and the surface of the object, and therefore the suction cup body is closely sucked to the surface of the object.

Description

technical field [0001] The invention relates to an air suction sucker, which belongs to the optimization technology of the sucker. Background technique [0002] Vacuum suction cups can be easily adsorbed on the surface of glass, tiles and other flat and smooth objects for hanging and grabbing objects. Since the vacuum suction cup can move and change positions at will, it is very convenient to use. Traditional vacuum suction cups are generally made of plastic materials with certain rigidity and certain flexibility such as silicone rubber or PVC material or 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 sel...
