Anti-falling device for computer power adapter

Abstract

The invention relates to the field of computers, in particular to an anti-falling device for a computer power adapter, which comprises an adapter main body, a take-up box, a take-up mechanism, a linkage mechanism, a telescopic hole, an adsorption mechanism, an auxiliary support mechanism and a connecting wire, and is characterized in that the lower end of the outer side of the adapter main body isfixedly connected with the take-up box; an upper through hole is formed in the middle of the upper end of each take-up box, and a lower through hole is formed in the middle of the lower end of the side, away from the adapter body, of each take-up box. A driven rotating shaft of the linkage mechanism drives a worm to rotate, a first threaded rod of the adsorption mechanism can rotate, accordingly,the lower end of the first threaded rod can pull a telescopic plate to slide, finally, the internal air pressure of a telescopic hole is reduced, and the adapter body can be adsorbed and fixed to a table top under the action of the internal and external air pressure difference of the telescopic hole. Therefore, the situation that the adapter main body slides on a desktop and finally the adapter falls off is effectively avoided.

Description

technical field [0001] The invention relates to the field of computers, in particular to an anti-drop device for a computer 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. Its working principle is converted from AC input to DC output. Press the connection The method can be divided into wall-plug type and desktop type, which are widely used in security cameras, set-top boxes, routers, light strips, massagers and other equipment. Most of the power adapters on the computer are connected between the power supply and the computer to charge the computer. power conversion. [0003] However, when the power adapter is directly placed on the desktop during use, due to insufficient friction between the main body of the adapter and the desktop, often ...

AI Technical Summary

Problems solved by technology

[0003] However, when the power adapter is directly placed on the desktop during use, due to insufficient friction between the main body of the adapter and the desktop, often when the desktop shakes, the main body of the adapter will slide on the desktop, eventually causing the adapter to fall to the ground, resulting in unpleasant Necessary loss, and both ends of the adapter are connected with a long cable. When the adapter is not in use, the cable will be dragged directly on the ground, causing stumbling or stepping on the cable. At the same time, when the desktop is impacted and shaken , the adapter cannot be guaranteed to remain stable on the life surface, which will cause the adapter to shake on the desktop, and in the absence of auxiliary support, due to the insufficient contact area between the bottom of the adapter and the desktop, the stability of the adapter cannot be guaranteed
