Suction cup

Abstract

The invention discloses a suction cup. The suction cup comprises an adsorption part and an elastic element, wherein the adsorption part is made of a soft material, the adsorption part comprises a mainbody and a skirt edge part, the skirt edge part is arranged around the main body, the main body is provided with a concave part, the skirt edge part is located at the edge of the concave part, the elastic element is arranged on the main body and is attached to the main body, the elastic element is continuous on the main body, the elastic element comprises elastic bodies, the plurality of elasticbodies are arranged at intervals, a notch is formed between every two adjacent elastic bodies, one end of each elastic body is provided with a pressing plate, the pressing plates are arranged at the edges of the elastic bodies and are attached to the skirt edge part, the notches extend to the pressing plates, and the skirt edge part and the pressing plates are horizontally arranged. According to the suction cup, the pressure intensity of the edge of the suction cup can be enhanced, the sealing performance between the edge of the suction cup and the curved surface is enhanced, and the pressurecontinuity of the edge of the suction cup is guaranteed, and the stability of the suction cup adsorbed on the curved surface is improved; and the suction cup is directly connected with the elastic element through a mounting part, the mounting capacity of the mounting part is enhanced, and the overall structural strength of the suction cup is improved.

Description

technical field [0001] The invention relates to a suction cup. Background technique [0002] A suction cup is a pendant that uses the difference between internal and external atmospheric pressure to adsorb on an object, or a tool for grabbing an object. Ordinary suction cups are generally used to adsorb on smooth and flat surfaces, such as glass, tiles, steel plates, etc. The suction cups are usually made of rubber materials, and the shape is usually bowl-shaped. However, when the existing suction cup is adsorbed on the curved surface, due to the radian of the curved surface, the pressure between the edge of the suction cup and the curved surface is discontinuous, stable, and the pressure is low, resulting in poor sealing between the suction cup and the curved surface. It is easy to enter from the edge, thereby reducing the degree of vacuum, and it is difficult for the suction cup to be firmly adsorbed on the curved surface. Contents of the invention [0003] In order to...
