Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to an environmentally friendly flame-retardant control cable. Background Art

[0002] Wires and cables refer to materials used for power, electrical and related transmission purposes. There is no strict boundary between "wires" and "cables". Usually, products with a small number of cores, small product diameters and simple structures are called wires, those without insulation are called bare wires, and the rest are called cables.

[0003] The cable sheaths on the market usually use flame-retardant materials. Flame-retardant layers of different materials are layered and sleeved on the cable body. The flame-retardant layer can prevent continuous burning after installation. However, due to the tight installation of the flame-retardant layer, the skin layer cannot be quickly removed when burning occurs, resulting in continuous burning of the cable. After burning, the skin layers stick to each other and are not easy to replace. Utility Model Content

[0014] 1. The utility model winds flame-retardant cloth, flame-retardant plastic and flame-retardant rubber on the cable body respectively, and the protective layer can be easily removed by winding. By adding inner seats to the ends of the flame-retardant cloth, flame-retardant plastic and flame-retardant rubber on both sides, the inner seats can clamp and limit the ends to ensure that they will not fall off automatically, thereby ensuring long-term protection of the flame-retardant layer. The installation of the inner seats can be carried out according to the protective position of the flame-retardant layer, making it more flexible. By arranging a slider on the inner seat, the slider can be extended and retracted according to the rotation of the knob, so as to clamp and fix the protective layer. When it needs to be removed, the reverse operation can be performed to loosen it, so that the entire burning layer can be removed separately, so that the burning point can be kept away from the cable to achieve flame retardancy, and later replacement is convenient.

[0015] 2. The utility model provides a sliding opening on the inner seat, and a slider is slidably connected in the sliding opening. One end of the slider is connected to a support rod, and the other end of the support rod is connected to a fixed seat of the knob. A limiting rod is provided on the fixed seat, and the support rod can be slidably connected to the limiting rod. Since the rotation position of the knob changes, the support rod can slide on the limiting rod to prevent being limited. When the knob is rotated as a whole, the support rod can gradually tend to be arranged in a straight line with the slider, and the slider can be pushed, thereby clamping and fixing the flame retardant layer.
