Sucking disc with elastic colloid
Technical Field
The invention relates to the technical field of articles for daily use, in particular to a sucker with elastic colloid.
Background
The sucker is often used in daily life of people, and is widely applied as the sucker is convenient to use and only needs to be adsorbed on base surfaces such as walls, object surfaces and the like without drilling walls or holes. The sucking disc is a household article which is directly fixed on the base surface by utilizing the internal and external pressure difference through being adhered to the base surface and forming a vacuum cavity in the middle part, is usually adsorbed on the wall surface, the counter surface and the like for hanging articles, and has the characteristics of convenient fixation and flexible displacement.
Most of the existing suckers are of vacuum adsorption structures, the suckers are provided with a tray body made of flexible materials such as soft rubber with a deep middle and a shallow periphery, the tray body is tightly attached to a base surface or the surface of an article, and the sucker is pressed to flatten and deform the tray body and attach the tray body to the base surface so that air between the tray body and the base surface is discharged, and therefore the tray body is adsorbed on the base surface.
