The suction cup is a household article which is fixed on a base surface by utilizing the difference between internal pressure and external pressure and is usually adsorbed on a wall surface, a cabinet surface and the like for hanging articles. The disk body of a sucking disk that now generally uses is formed by the skeleton rubber coating, is equipped with the dish cover outside the disk body, is equipped with the connecting portion of connecting couple etc. on the disk body. The framework of the sucker has the function of supporting and shaping the rubber coating layer on the framework, can conduct stress to discharge air in the rubber coating layer, and meanwhile extrudes and clings the rubber coating layer of the disc body to a base surface. When the vacuum sucking disc is used, the sucking disc is placed on a base surface, the bottom surface of the disc body faces the base surface, then connecting pieces such as the hooks are pressed, the connecting pieces press the disc cover, the disc cover compresses the disc body, the disc cover and the framework are enabled to be deformed inwards, air in the disc body is exhausted, then the disc cover and the framework rebound under the action of deformation force, the bottom of the disc body is pulled upwards to form a vacuum cavity, vacuum is generated between the central portion of the bottom surface of the disc body and the base surface, the edge of the bottom surface of the disc body is attached to the base surface to seal the vacuum cavity, and therefore the sucking disc is adsorbed on the base surface. The supporting force of the framework is too small, so that although the deformation of the disc body is easier, the gas discharge time in the disc body is shortened rapidly, and the gas in the disc body can not be discharged completely; the supporting force and the resilience force of the framework are too large, the compression force required for fixing the disc body is increased, the sucking disc is not easy to adsorb on a base surface, and meanwhile, the sucking disc body adsorbed on the base surface can be greatly stripped, so that the close attaching degree of the disc body and the base surface is influenced. For example, the invention patent CN104956100B discloses a bowl-shaped skeleton vacuum chuck, which comprises a skeleton, a chuck body, a lower chuck cover, a connecting rod and the like, the chuck has strong adsorption force, but the skeleton of the chuck is divided into a plurality of pressing sheets, and the separation seam of each pressing sheet penetrates to the central point, so that the pressure transmitted by the skeleton to the edge of the adhesive coating layer, namely the edge of the chuck body, is weak when the chuck is pressed down, the supporting force and the resilience force of the skeleton are too small, the vacuum cavity formed by pulling up the bottom of the chuck body is small, the vacuum degree of the vacuum cavity is low, and the adsorption force is small. In addition, the rubber coating layer formed by injection molding on the framework has the problem that the rubber coating layer is easy to separate from the edge of the framework or displace due to soft texture.

The setting of cooperation arch and bar seam further plays axial and radial effect of blockking to the colloid on the skeleton body, avoids the colloid to break away from or take place the displacement from the skeleton. The arc-shaped arrangement of the separation seams can enable the pressing sheets to generate a trend of rotating along the arc in the process of pressing down the colloid, thereby being beneficial to the trend of generating rotary expansion when the circular colloid edge is pressed down, enabling the colloid to be more extended and more tightly attached to a base surface, and providing space for the downward pressing deformation of the framework body. The separation seam and the strip seam are arranged at intervals, so that the problem that the root of a pressing sheet is too narrow and the stress and the force transmission are weak due to the fact that the pressing sheet is extended to the central part of the disc body due to the fact that the separation seam and the strip seam are overlapped in the prior art, and the problem that the framework supporting force and the resilience force are too small is solved. Be conical skeleton body inner wall than bowl shape structure in the past, the resilience force at skeleton body center is further strengthened, and the bottom of disk body is bigger by the vacuum cavity of upwards pulling up formation, and the vacuum degree of vacuum cavity is high, and the disk body adsorption affinity is bigger.
