Elastic colloid for sucker and vacuum sucker applying elastic colloid

Abstract

The invention discloses an elastic colloid for a sucker and a vacuum sucker applying the elastic colloid. The elastic colloid for the sucker comprises an elastic framework. A connecting rod is arranged at an upper portion of the framework. The framework is coated with a colloid body. An adsorption cavity with an opening in a lower portion is arranged in a bottom of the colloid body, the connecting rod can pull and press the framework to make the colloid body be adsorbed on an adsorbed surface, the adsorption cavity gradually expands outwards from top to bottom, a conical surface is arranged on a side wall of the adsorption cavity, a top wall is arranged above the conical surface, and a combination portion is formed between the top wall and the conical surface. A height from a vertex of the adsorption cavity to a lower edge of the conical surface is H, a circumferential diameter of the lower edge of the conical surface is D, and the H and the D satisfy the following relational expression: 0.05 < / = H / D < / = 0.10. An included angle alpha between the conical surface and the adsorbed surface is greater than or equal to 10 degrees and is less than or equal to 17 degrees. An adhesion degree of the colloid body and the adsorbed surface is very good, an adsorption force is lasting, and the colloid is not easy to fall off.

Description

technical field [0001] The invention relates to an elastic colloid for a sucker and a vacuum sucker using the elastic colloid. Background technique [0002] Vacuum suction cup is a product that can be adsorbed on the wall. A hook is provided on the back of the suction cup, which can be used for hooking daily articles, is very convenient to use, and has been widely used in ordinary families at present. [0003] The structure of a common vacuum suction cup is that it includes elastic colloid for absorbing the wall. The bottom surface of the elastic colloid is provided with a deep and shallow pot-shaped adsorption cavity in the middle. The middle part of the upper surface of the elastic colloid is connected with a pressing piece. The suction cup cover surrounded by the upper part of the elastic colloid can deform the elastic colloid by pressing the pressing part, extruding part of the air in the pot-shaped adsorption cavity, so that the suction cup is sucked tightly on the wal...

Problems solved by technology

However, there are also many problems in this flat suction cup. First, it is inconvenient to install. When installing this flat suction cup, the gas between the suction cup body and the wall must be driven out little by little, which takes a long time; When professionals install this kind of suction cup, most of them will have a lot of air bubbles between the suction cup body and the wall due to incorrect operation methods. As a result, the suction cup body and the wall surface have poor fit and are easy to fall off
