Self-absorption base structure

Abstract

The invention provides a self-absorption base structure. The self-absorption base structure comprises a first chassis, a second chassis is sleeved with the first chassis, the bottom of the second chassis is sleeved with a suction cup, a first hollow boss which is formed through integral injection molding is arranged in the middle of the first chassis, the first hollow boss is slidingly sleeved with a columnar protrusion formed in the middle of the second chassis in an injection molding manner, and the columnar protrusion is slidingly sleeved with the second hollow boss formed in the middle ofthe suction cup in an injection molding manner, the first hollow boss, the columnar protrusion and the second hollow boss are in sequential sliding fit, self gravity of the first chassis and the second chassis is used for deforming the suction cup, vacuum is rapidly formed between the suction cup and the contact face, adsorption is finished, a lifting column is in fit with a seal pad, and the accident falling caused by air entering in the suction cup during absorbing of a self-absorption base can be prevented.

Description

technical field [0001] The invention belongs to the technical field of self-suction seat manufacture, and in particular relates to a self-suction seat structure. Background technique [0002] In the prior art, the sucker equipment is a tongue-pressing prying structure to make the sucker generate adsorption force. This kind of sucker will lift the pull rod by pressing down the elastic handle, and then drive the sucker to lift, so that the bottom of the sucker will generate Negative pressure makes the suction cup have adsorption force and is tightly adsorbed on the plane. [0003] However, this suction cup structure needs to be installed with a prying mechanism, the upper cover needs to be installed with a gap, and the direction is fixed, so this suction cup structure takes up a lot of space during use, and it is not labor-saving when used. , the operation is also comparatively loaded down with trivial details, causes the use of suction cup to have many inconveniences. Cont...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a self-suction seat structure, which aims to solve the need to install a prying mechanism in the existing suction cup structure, the upper cover needs to be installed with a gap, and the direction is fixed, so this suction cup structure takes up space during use It is relatively large, and it is not labor-saving enough to use. At the same time, when the existing suction cup is disassembled, the operation is relatively cumbersome.
