Multi-plug automatic winding displacement digital display power disc

Abstract

The invention discloses a multi-plug automatic winding displacement digital display power disc which comprises a rack body. The rack body is provided with an automatic winding displacement device, multifunctional pluggable type plugs, a digital display voltmeter, overheat protectors and a leakage protector. The automatic winding displacement device comprises a fixing shaft, a power disc body, two chain wheels, a chain, a reciprocating lead screw and a nut. The overheat protectors are all arranged in the power disc body. The multifunctional pluggable type plugs, the digital display voltmeter and the leakage protector are all arranged on the power disc body. The power disc body is arranged on the fixing shaft in a sleeving mode. The fixing shaft is sleeved with the first chain wheel, the second chain wheel is arranged at the end of the reciprocating lead screw, and the two chain wheels are in transmission through the chain. The reciprocating lead screw is sleeved with the nut, a cable guide mechanism is arranged below the nut, and the cable penetrates through the cable guide mechanism and then is wound on the power disc body. The multi-plug automatic winding displacement digital display power disc has the advantages of being capable of improving the take-up and pay-off efficiency of the power disc body, safe to use, high in reliability, capable of lowering the low voltage electric shock risks of workers and the like.

Description

technical field [0001] The invention relates to a multi-plug automatic wiring digital display power supply panel. Background technique [0002] The power tray is a movable power cord tray with wires and cables wrapped around it. The power tray is equipped with a national standard socket or an industrial socket, a leakage protector and a power indicator light, and is used as an outdoor power supply. Most on-site work requires the use of low-voltage AC power. However, there are many defects in the traditional power panel currently used. As a result, low-voltage electric shock has always been a major safety hazard when receiving and repairing the power supply. The inconvenience and safety hazards are problems that need to be solved urgently. There are six major problems with traditional power panels: [0003] (1) Waste of human resources [0004] When the traditional power panel is wound up, two people are usually required to operate it. One person fixes the power panel frame...

AI Technical Summary

Problems solved by technology

If one person takes up the line, it is necessary to use both hands and feet, the operation is complicated, and holding the power line is easy to cause damage to the palm;

[0005] (2) Poor take-up effect, affecting work efficiency

[0006] The traditional power supply tray usually has loose wires, and the power cord cannot be guaranteed to be neat and fastened. When the power cord is unwound next time, it may cause the power cord to be entangled and cannot be pulled out smoothly. At this moment, it takes a lot of time to organize the power cord. Seriously affect work efficiency;

[0007] (3) Poor adaptability

[0008] Different workplaces have different on-site maintenance power interfaces, usually including different types of sockets and terminals, while traditional power panels only have one type of plug fixedly connected to them. disassembly and fabrication of

[0009] (4) Hidden danger of electric shock

[0010] Due to the repeated and repeated removal and manufacture of the plug, the insulation layer of the power line of the traditional power supply panel will be damaged. Once the staff touches the exposed copper wire when receiving the power supply, it will cause personal electric shock accidents, and there is a large security risks;

[0011] (5) The accuracy of instrument data cannot be guaranteed

[0014] When the power cord is not fully withdrawn, the heat dissipation performance is poor due to being entangled

If the power is on for a long time, even if the current does not reach the action value of the leakage protector, it may cause accelerated aging of the insulation layer of the power cord due to overheating, or even fuse and catch fire. The contact resistance between plugs and sockets will continue to increase, which may also cause the insulation layer to age, melt, carbonize or even catch fire due to overheating, which has great potential safety hazards for personal safety and equipment safety.
