Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to an electric wire and cable with a long service life. Background Art

[0002] A cable is usually a rope-like cable made up of several or several groups of wires (at least two in each group). Each group of wires is insulated from each other and often twisted around a center wire, with the entire outside covered with a highly insulating covering.

[0003] However, in the prior art, some cables need to be hung on the wall by cable hooks due to position issues during installation. However, when the cables are hung on the wall by the cable hooks for a long time, the unsupported parts of the cables will slowly bend downward because they are always floating in the air. As the cables are bent for a long time, the battery cells inside the cables may also be scrapped due to the bending problem, thereby reducing the life of the cables. Utility Model Content

[0004] The utility model mainly provides an electric wire and cable with a long service life, which enables the cable to be always in a straight state and avoids the scrapping of the electric core due to bending.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a kind of electric wire and cable with long service life, comprising: two fixed blocks, the front surfaces of the two fixed blocks are welded with fixed plates, the front surfaces of the two fixed blocks are welded with connecting plates, the inner surfaces of the two connecting plates are movably inserted with movable frames, and the outer surfaces of the two movable frames are respectively fixedly connected with the two fixed plates by screws and bolts, the inner surfaces of the two movable frames are rotatably inserted with threaded rods, one end of the outer walls of the two threaded rods is movably sleeved with movable plates, the inner surfaces of the two movable plates are provided with cable bodies, and the outer surfaces of the cable bodies are fitted with the inner surfaces of the two fixed plates, the tops of the two fixed blocks are welded with fixed frames, the inner surfaces of the two fixed frames are movably inserted with rollers, one side of the outer walls of the two fixed frames is fixedly inserted with return mechanisms, and the output ends of the two return mechanisms are respectively fixedly connected with one end of the outer walls of the two rollers, the outer surfaces of the two rollers are wound with fixed ropes, the outer walls of the fixed ropes are fixedly sleeved with connecting blocks, and the inner surface wall of the connecting block is fixedly sleeved on the outer wall of the cable body;

[0006] The cable body comprises three battery cores, the outer surfaces of the three battery cores are all fixedly sleeved with insulating layers, and the outer surfaces of the three insulating layers are all fixedly sleeved with filling layers.

[0007] Compared with the prior art, the advantages and positive effects of the utility model are:

[0008] 1. In the utility model, the outer wall of the cable is tightened and fixed by setting a fixing block, and then installed on the wall, and then connected to the cable body through the fixing rope and the connecting block. In this way, during the daily operation of the cable, the connecting block and the fixing rope are connected and suspended in the floating area of ​​the cable, thereby avoiding the problem of cable sagging. At the same time, if the impact of foreign objects on the cable body causes the fixing rope to bend, the return gear on the return mechanism will drive the drum to rotate, so that the fixing rope returns to a taut state, and the floating part of the cable body is suspended and supported, thereby avoiding the problem of easy scrapping of the battery core due to bending of the cable body, and improving the life of the cable body.

[0009] 2. In the utility model, the outer lining layer is a PVC outer lining layer. By utilizing the elastic characteristics of PVC, when the cable body is impacted, it can quickly return to a straight state with the traction of the fixed rope to avoid damage caused by bending. At the same time, the rotating and anti-slip rubber is provided to facilitate fixing the cable body with the movable plate and the fixed plate, thereby preventing the cable body from slipping between the fixed plate and the movable plate, causing the cable body to loosen, thereby improving the stability of the entire cable.

[0018] The cable body 7 includes three battery cores 701 . The outer walls of the three battery cores 701 are all fixedly sleeved with insulating layers 702 . The outer walls of the three insulating layers 702 are all fixedly sleeved with filling layers 703 .

[0019] like Figure 5 As shown, the outer wall of the filling layer 703 is fixedly covered with an inner lining layer 704, and the outer wall of the inner lining layer 704 is fixedly covered with an outer lining layer 705, wherein the outer lining layer is a PVC structure. When the cable body 7 is bent, the elastic properties of PVC can be utilized to assist the cable body 7 to return to a straight state.

[0020] like Figure 3 As shown, the outer walls of the two threaded rods 6 are fixedly sleeved with knobs 13, so that when installing the cable body, the knobs 13 can be held to make the threaded rods 6 more convenient to rotate.

[0021] like Figure 3 As shown, a set of limit blocks 16 are fixedly installed on one side of the outer wall of the two movable plates 5, and the outer walls of the two sets of limit blocks 16 are movably inserted into the inner walls of the two movable frames 4, so as to limit the movable plates 5 when the threaded rods 6 move the positions of the movable plates 5.

[0022] like Figure 3As shown, guide frames 14 are welded to the tops of the two fixed blocks 1, guide rollers 15 are movably inserted into the inner walls of the two guide frames 14, and the outer walls of the two guide rollers 15 are in contact with the outer walls of the fixed rope 11, so as to guide the fixed rope 11 and make the drum 9 more stable so that it will not be easily pulled up and rotated by the fixed rope 11.

Since the roller 9 on the fixing agent is connected to the return mechanism 10, it can be The two rollers 9 are kept in a rotating state so that the fixing rope 11 can be in a taut state. The taut fixing rope 11 will suspend the cable body 7 in a floating state through the connecting block 12, thereby preventing the floating area of ​​the cable body 7 from sagging. When a foreign object impacts the cable body 7, the cable body 7 and the fixing rope 11 will be in a bent state, allowing the roller 9 to rotate a certain angle. At this time, the return mechanism 10 will drive the roller 9 to return due to the rotation of the roller 9, thereby tightening the fixing rope 11 into a taut state again, and the cable body 7 will return to a straight state through the elastic properties of its own outer lining layer 705 and the pull of the fixing rope 11.
