Problems solved by technology
[0005] Aiming at the problems existing in the prior art, the object of the present invention is to provide an isolated wear-resistant and drag-resistant cable sheath, through the setting of multiple fixed fixed guards and movable movable guards, on the one hand Effectively control the bending angle of the cable, effectively avoiding local damage and cracking of the cable due to excessive bending. The sheet directly slides with the ground. Compared with the existing technology, it effectively avoids the direct friction between the cable and the ground, thereby greatly reducing the problem of reduced life due to friction. In addition, with the setting of the air-gathering drum, when dragging, the air-gathering drum The drum piece is squeezed, and the gas inside lifts up the light air-capped ball, causing the self-crushing lubricant powder to fall, thereby improving the smoothness of the movement of the cable when it is dragged, and further reducing friction damage

Embodiment 1
[0035] see figure 1 , a in the figure represents a cable, an isolated wear-resistant and drag-resistant cable sheath, including a plurality of evenly distributed fixed protection sheets 2 connected to the outside of the cable and a plurality of fixed protection sheets 2 spaced apart from each other. The moving shield 1, the moving shield 1 is set outside the cable, through the setting of the moving shield 1 and the fixed shield 2, the cable is effectively isolated from the ground, and the adjacent moving shield 1 and the fixed shield 2 are connected There are a plurality of evenly distributed two-way position control ropes 3. In the natural state, the two-way position control ropes 3 are in a stretched state, and the two-way position control ropes 3 are elastic structures, so that when dragging occurs, such as Figure 2-3 , the arrow in the figure shows the moving direction of the cable when it is dragged. Under the friction of the dragging force, the moving guard 1 can tilt a...

The invention discloses an isolated wear-resistant and anti-dragging cable sheath, which belongs to the field of cables. Through the arrangement of a plurality of fixed protective sheets and movable protective sheets, on one hand, the bending angle of a cable is effectively controlled, and the phenomenon that the cable is partially damaged and cracked due to excessive bending is effectively avoided; on the other hand, when a dragging phenomenon occurs, the movable protective sheet is obliquely close to and abuts against the fixed protective sheet, so that the fixed protective sheet directly slides on the ground. Compared with the prior art, direct friction between the cable and the ground is effectively avoided, and the problem that the service life is shortened due to friction is greatly solved; in addition, in cooperation with the arrangement of a gas gathering drum piece, during dragging, the gas gathering drum piece is extruded, gas in the gas gathering drum piece jacks up a light gas jacking ball, and the self-breaking lubricating powder falls, so that the moving smoothness of the cable during dragging is improved, and friction damage is further reduced.
Description
technical field [0001] The invention relates to the field of cables, more specifically, to an isolated wear-resistant and drag-resistant cable sheath. Background technique [0002] The cable is usually a rope-like cable twisted by several or several groups of wires. Each group of wires is insulated from each other and is often twisted around a center. The entire outside is covered with a highly insulating covering. A protective covering can be added to transmit, distribute electrical energy or transmit electrical signals. The difference between it and ordinary wires is that the cable size is larger and the structure is more complicated. [0003] When the cable needs to be exposed to the ground during installation or use, it is often prone to dragging, resulting in bending and abrasion of the cable, which not only affects its own service life, but also easily causes safety hazards of leakage. Contents of the invention [0004] 1. technical problem to be solved [0005] A...
