Automatic retractable low-tension cable lengthening device

Abstract

The invention relates to the field of cable assembly, in particular to an automatic retractable low-tension cable lengthening device including a fixing device, a retractable device, a cable assembly and a monitoring device, wherein, the fixing device is used for bearing the rest components; the cable assembly includes a cable and a socket, one end of the cable is connected to the socket, and the other end of the cable is welded to a roller in a split-conductor mode; the retractable device includes a roller, an electric brush assembly, a motor and a processor, the motor drives the roller to operate the retractable operation of the cable under the control of the processor, and the electric brush assembly is used to transfer electric current of the cable which is welded to the transmission roller; and the monitoring device includes a column and a sensor, the sensor is used to check and test the height of a cable space position and sends the position information to the processor, and the processor controls retracting of the cable. The automatic retractable low-tension cable lengthening device operates under the coordination of the processor, can meet the requirement of lengthening thecable, can be retracted automatically, and can eliminate resistance of a pulling cable of an electric appliance which is connected with the socket.

Description

technical field [0001] The invention relates to the field of cable fittings, in particular to an automatically retractable low-voltage cable extension device. Background technique [0002] For low-voltage power supply appliances with mobile functions, if a fixed-length cable is used for power supply, the appliance will move with a long cable, which will virtually increase the movement resistance of the appliance and accelerate the wear of the cable. On the other hand , the long cable is coiled on the ground, which is easy to be entangled and difficult to untie. Therefore, a low-voltage cable extension device with automatic retractable function has emerged as the times require. Contents of the invention [0003] Aiming at the problems in the prior art, the present invention provides an automatically retractable low-voltage cable extension device. Eliminates the resistance of pulling cables of electrical appliances connected to the socket. [0004] In order to achieve the ...
