Plane sucker base

Abstract

The invention relates to the field of suckers and provides a plane sucker base. The plane sucker base consists of a sucker body and a screw, wherein the bottom surface of the sucker body is a suction surface of a plane structure, the top surface of the sucker body is a step surface which is gradually thinned from the middle to the edge, and a boss is arranged in the center of the step surface; the screw consists of a nut and a screw rod, the nut is positioned in the boss, and the screw rod is positioned outside the boss; at least one through hole is formed in the plane of the nut, and after a sucker body material in the boss is infused into the through hole, an integral structure is formed by the boss and the nut to form a bottom disc of the plane sucker. Compared with the prior art, the plane sucker base can prolong suction time and can bear heavier objects.

Description

technical field [0001] The invention relates to the field of suction cups, in particular to a plane suction cup base. Background technique [0002] At present, the hooks with suction cups on the market generally use the concave suction cup base close to the smooth wall, and then press the suction cup base to discharge the air in the concave suction cup base, and the hook can be adsorbed by the atmospheric pressure outside the suction cup On the wall, this kind of suction cup hook has a beautiful appearance and does not damage the wall, and is widely used by people. However, we will all find that after a period of time or when the weather turns cold, the suction cup hook will automatically fall off even if the item is not hung, and the frequency of falling off after hanging the item or when hanging the heavier item will be higher. On the one hand, when the suction cup is first adsorbed on the wall, the air in the concave area may not be completely removed, and after a period...

Problems solved by technology

However, we will all find that after a period of time or when the weather turns cold, the suction cup hook will automatically fall off even if the item is not hung, and the frequency of falling off after hanging the item or when hanging the heavier item will be higher. On the one hand, when the suction cup is first adsorbed on the wall, the air in the concave area may not be completely removed, and after a period of use, the external air will gradually enter the concave area under the suction cup base. When the air pressure entering the shaped area is the same as the external air pressure, the suction cup hook will fall off; on the other hand, the connecting part hooked between the suction cup base and the suction cup base are two separate parts, and the connecting part will stretch when hanging heavy objects Suction cup base is deformation of the suction cup base, which in turn further exacerbates the ingress of outside air into the concave area of ​​the suction cup base
