detailed description

Below in conjunction with accompanying drawing and embodiment, further elaborate the present invention. In the following detailed description, certain exemplary embodiments of the invention are described by way of illustration only. Needless to say, those skilled in the art would realize that the described embodiments can be modified in various different ways, all without departing from the spirit and scope of the present invention. Accordingly, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

As shown in Figure 1, the power communication cable retractable device includes a cable frame 1, a drive device is installed on the cable frame 1, and a power output end of the drive device is connected to a cable retractable shaft 2, so The drive device includes a motor 3, the motor 3 is connected to a gearbox 4, and the motor 3 and the gearbox 4 are used to output power to drive the cable retracting shaft 2 to rotate, when the motor 3 When the motor 3 rotates in the forward direction, the cable is released, and when the motor 3 is reversed, the cable is taken up.

In this embodiment, an outwardly rotatable shaft stand 5 is installed on the cable rack 1 corresponding to the end of the cable retracting and releasing shaft 2 away from the driving device, and the shaft stand 5 is provided with a receiving place. The semicircular notch 6 of the cable retractable shaft 2 is provided with an anti-friction device for the retractable shaft in the notch 6,

On the cable take-up and release shaft 2 between the driving device and the shaft stand 5, the wire retaining disk 7 and the movable wire retaining disk 8 are relatively set and fixed, and the outer side of the movable wire retaining disk 8 is provided with a stop The wire reel limit device, the surface of the cable retractable shaft 2 is provided with connecting threads, the wire retaining reel limit device is screwed and sleeved on the outer periphery of the cable retractable shaft 2, and the cable rack 1 Also installed on the take-up line guide. The anti-friction device for retractable shaft includes a plurality of balls rotatably embedded in the notch 6 , and the surfaces of the balls protrude from the surface of the notch 6 . When the cable take-up and release shaft 2 rotates under the drive of the motor 3, it will inevitably rub against the notch 6. After the ball is provided, the friction force can be reduced, which contributes to Prevent the cable take-up and release shaft 2 from wearing and tearing.
