Description

Technical Field

[0001] The utility model relates to the technical field of cable reeling, in particular to a weak-current cable reeling device. Background Art

[0002] Cable is a general term for items such as optical cables and electrical cables. Cables have many uses, mainly used for controlling installation, connecting equipment, transmitting electricity and other multiple functions. They are common and indispensable in daily life. In the process of cable production, reels are needed to wind the cables.

[0003] The existing weak-current cable retractor has a simple structure. When the cable is reeled in, the cable is prone to shaking, which makes the reeled cable uneven and difficult to stack. In addition, when unfolding the cable, the existing weak-current cable retractor needs to manually pull the head end of the cable, which is prone to excessive force causing the copper wire inside the cable to break.

[0006] Preferably, a rotating handle is provided at one end of any one of the brackets, and one end of the rotating handle passes through the bracket and is connected to the reel. When reeling in the low-voltage cable, the rotating handle is rotated to drive the reel to rotate, and the cable is reeled on the outer surface of the reel.

[0007] Preferably, the bottoms of the two frames extend into the long groove, and the frames are limited by the long groove, so that the frames can perform linear motion at the top of the bottom plate, thereby ensuring the stability of the frame movement.

[0008] Preferably, a fixing frame is detachably mounted on the bottom end of the base in front of the protective shell, two support plates are arranged on the top of the fixing frame, a conveyor belt is arranged between the two support plates, one side of the conveyor belt extends out of the outside of any one of the support plates, and a servo motor is arranged on the extended end of the conveyor belt. When the reeled cable needs to be unfolded, the fixing frame is installed at the bottom end of the base, and the support plate installs the conveyor belt at a predetermined position. The conveyor belt is driven by the servo motor to run, so as to facilitate the transportation and unfolding of the cable.

[0009] Preferably, two limit sleeves are provided at the top of the two support plates, and the limit sleeves are in an inverted U shape. The two limit sleeves form a group, and columns are provided inside each group of limit sleeves. The outer surfaces of the columns between the two limit sleeves in each group are provided with downward pressing rotating cylinders. When the cables are laid and unfolded, the cables pass between the conveyor belt and the downward pressing rotating cylinder, and the downward pressing rotating cylinder presses the cables down and clamps them so that they can be conveyed by the conveyor belt for unfolding and laying.

[0010] Preferably, a telescopic rod is provided inside the limiting sleeve at the bottom of the column, and a return spring is provided on the outer surface of the telescopic rod. When the cable is unfolded and laid, the column is first pulled upward to extend the telescopic rod, and the return spring is pulled. After the cable passes through the conveyor belt and the downward pressing rotating cylinder, the column is loosened, and the return spring pulls the column downward. The cable is clamped by the downward pressing rotating cylinder, so that the top end of the cable contacts the conveyor belt.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. This weak-current cable retractor is used in conjunction with a protective shell and a frame. The cable is passed through the opening of the protective shell and placed between the two frames. The frame contracts inward through a tension spring to clamp the cable. The cable contacts the drum, and then one end of the cable is fixed to the outer surface of the reel. The handle is turned to drive the reel to rotate and the cable is reeled on the outer surface of the reel to avoid large shaking of the cable during reeling, which results in uneven reeling.

[0013] 2. This weak-current cable retractor is used in conjunction with a conveyor belt and a downward-pressing rotating drum. When the retracted cable needs to be unfolded and used, first install the fixing frame on the bottom end of the base, then pass the head end of the cable through between the conveyor belt and the downward-pressing rotating drum, pull the column upward to extend the telescopic rod, and the reset spring is pulled. After the cable passes through between the conveyor belt and the downward-pressing rotating drum, release the column, and the reset spring pulls the column downward to cause the downward-pressing rotating drum to press the cable down and clamp it, so that the bottom end of the cable contacts the conveyor belt, and then the servo motor starts to drive the conveyor belt to convey and unfold the cable, making it more convenient to unfold and use the cable, without manually pulling the head end of the cable, to avoid the breakage of the copper wire inside the cable.
