Air pressure adsorption type power adapter

Abstract

The invention discloses an air pressure adsorption type power adapter, which comprises an adapter body, an opening is arranged at the bottom end of the inner cavity of the adapter body, a suction cup is arranged at the lower end of the motion chamber, and the top end of the motion chamber is connected to the adapter body. The top end of the inner chamber of the adapter body is connected, the side wall of the adapter body is provided with an L-shaped motion slideway, the lower end of the inner chamber of the motion chamber is provided with a piston, and the first support rod runs through the lower end of the transmission column. Function, so that when the user uses the power adapter, it can be fixed by the negative pressure generated inside, so that it will not fall off, so that the service life of the power adapter is improved to a certain extent, and the invention can make the power adapter It does not affect the use of electrical appliances when being involved, and has a certain protective effect on electrical appliances. The invention can conveniently fix its own position through the adjustment of air pressure, and has strong practicability.

Description

technical field [0001] The invention relates to the technical field of power adapters, in particular to an air pressure adsorption type power adapter. Background technique [0002] The power adapter is a power supply conversion device for small portable electronic equipment and electronic appliances. It is generally composed of housings, transformers, inductors, capacitors, control ICs, PCB boards and other components. The power adapter is a commonly used accessory for household appliances. When the power adapter is used When using it, it needs to be connected to the electrical appliances through the power line, and many power adapters often need to be placed on the floor, desktop, etc. The phenomenon of being kicked or smashed, the traditional power adapter itself cannot fix the position, which will affect the user's use, and often cause the electrical appliance to fall due to the power adapter, which is harmful to the user's attention to the electrical appliance Normal us...

[0002] The power adapter is a power supply conversion device for small portable electronic equipment and electronic appliances. It is generally composed of housings, transformers, inductors, capacitors, control ICs, PCB boards and other components. The power adapter is a commonly used accessory for household appliances. When the power adapter is used When using it, it needs to be connected to the electrical appliances through the power line, and many power adapters often need to be placed on the floor, desktop, etc. The phenomenon of being kicked or smashed, the traditional power adapter itself cannot fix the position, which will affect the user's use, and often cause the electrical appliance to fall due to the power adapter, which is harmful to the user's attention to the electrical appliance Normal use causes a lot of trouble. Because the power adapter itself cannot be fixed, it will fall, which will greatly damage the working life of the power adapter. Moreover, the traditional power adapter does not have the function of buffering external impacts. The power adapter itself is damaged to a certain extent, further reducing the service life of the power adapter
