A cable automatic retracting device

Abstract

The invention relates to the field of cable accessories, in particular to an automatic cable take-up and pay-off device, comprising a fixing device, a take-up and pay-off device, a cable assembly anda monitoring device, wherein the fixing device is used for carrying other 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 reel assembly in a strand-splitting manner; the take-up and pay-off device comprises the reel assembly, an electric brush assembly, a motor and a processor; under the control of the processor, the motor drives the reel assembly to carry out the take-up and pay-off work of the cable, and the electric brush assembly is used to transfer the current of the cable welded onthe reel assembly; the monitoring device consists of a column and a sensor which detects the height of the cable space and feeds the position information back to the processor which determines the take-up or pay-off of the cable. The device works under the coordination of the processor, can realize the demand of lengthening the cable, and can achieve automatic take-up and pay-off and eliminates the resistance, of pulling the cable, of an electric appliance connected by the socket.

Description

technical field [0001] The invention relates to the field of cable fittings, in particular to an automatic cable retracting device. Background technique [0002] For low-voltage electrical appliances with mobile functions, if a fixed-length cable is used to connect them, the electrical appliance will move with a long cable, which will virtually increase the movement resistance of the electrical appliance and accelerate the wear of the cable. On the other hand , the long cable is coiled on the ground, it is easy to be entangled and difficult to untie, and the cable composition of different electrical appliances is different, and the structure of the extended cable needs to be customized according to its structure. Therefore, an automatic retractable function That's where custom cable extensions come in. Contents of the invention [0003] Aiming at the problems in the prior art, the present invention provides an automatic cable retracting device, which has a simple and clea...
