Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of daily necessities, especially a skeleton for a suction cup and the suction cup. BACKGROUND

[0002] The suction cup is a household item that is fixed on a base surface by forming a vacuum cavity in the middle and using the pressure difference between the inside and outside to directly fix on the base surface, and is usually used for hanging objects on a wall surface, a cabinet surface, etc., and has the characteristics of convenient fixing and flexible displacement.

[0003] A commonly used suction cup has a disc body made of a skeleton and rubber, and the skeleton and the disc body are bowl-shaped with a deep middle and shallow periphery. The disc body is formed by secondary injection molding and covers the skeleton. The skeleton of the suction cup supports and shapes the rubber layer thereon, and the skeleton can conduct stress to expel air in the rubber layer and extrude the rubber layer of the disc body to tightly adhere to the base surface. In use, the disc body is tightly adhered to the base surface or the surface of an object, and the disc body is pressed to deform and adhere to the base surface by pressing the suction cup, so that air between the disc body and the base surface is expelled. Subsequently, the disc cover and the skeleton rebound under the action of the deformation force, so that the middle part of the suction cup has a tendency to protrude upward. A vacuum is generated between the central part of the bottom surface of the disc body and the base surface, and the bottom surface edge of the disc body adheres to the base surface to close the vacuum cavity, so that the suction cup is adsorbed on the base surface. However, the disc body formed by injection molding on the skeleton is soft in texture, so the rebounding force of the skeleton is greater than the rebounding force of the disc body. The friction between the disc body and the base surface prevents the disc body from retracting. In particular, the edge of the skeleton is divided into several pressing pieces, which makes the edge of the skeleton easily separate from the edge of the disc body and causes delamination. After delamination, the supporting and extruding force of the skeleton on the edge of the disc body is weakened, and the edge of the disc body is prone to warping after long-term use, which affects the adsorption strength of the suction cup. SUMMARY

[0004] The utility model aims to provide a skeleton for a suction cup, which is closely connected with a disc body covering the outer side of the skeleton, and the edge of the skeleton does not separate from the edge of the disc body.
