Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of weak current system especially relates to a cable take -up device for weak current system. BACKGROUND

[0002] Power applications can be divided into two categories according to the strength of power transmission power, namely strong current and weak current. Among them, the weak current in intelligent building mainly has two categories. One is the low voltage power of national safety voltage level and control voltage, which is divided into alternating current and direct current. The alternating current is below 36V, and the direct current is below 24V, such as 24V direct current control power supply or emergency lighting lamp standby power supply. The other is information source carrying voice, image, data and other information, such as telephone, television and computer information. The weak current technology in intelligent building is more and more widely used, such as intelligent fire fighting system, monitoring system, computer network, building automatic control, intelligent broadcast and so on. Cable, as the carrier of electricity, is an indispensable thing in daily life, which has various purposes, mainly used for control installation, connection equipment, power transmission and other functions. The cable needs to be taken up and put down during use, so the cable take -up device is used.

[0003] Through retrieval, the patent with the patent publication number CN112061897A discloses a cable take -up device for power system convenient to move, which solves the technical problem that the cable cannot be neatly discharged during the taking -up and putting -down process, which affects the taking -up and putting -down effect. The motor driven winding roller is arranged to take up and put down the cable, and the transmission assembly is arranged to drive the groove roller to rotate. When the groove roller rotates, the connecting assembly and the guide ring connected therewith are driven to reciprocate to ensure that the winding roller neatly winds the cable. The driving mechanism is arranged to change the vertical position of the guide ring when it moves to the two ends of the winding roller to ensure that the guide ring is attached to the winding roller for guiding. However, there are still the following disadvantages to be solved: the cable has no tension during winding, and the cable is slightly curved or even has a large bending angle, which causes the cable to be unable to keep neat after winding.
