When using cables, they need to be threaded first.
[0003] When the existing cable threading structure passes through the cable, the cable will rub against the cable passing structure, resulting in greater friction when the worker is threading the cable, making it more difficult to move the cable, causing the worker to consume more energy quickly, and may also cause thinner cables to break due to the difficulty in threading, thereby reducing the threading efficiency;
[0004] Moreover, most of the existing wire-passing structures can only thread wires for pipes of one thickness and cannot be adjusted according to the width of the pipe. If the pipe is thicker or thinner, the staff needs to replace the device, which has poor applicability and high cost of replacing the device, causing inconvenience to the wire-passing and wasting the staff's time.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] See also Figure 1-4 As shown, a wire-passing structure for cable threading comprises an outer ring 1 and an inner ring 2 installed inside the outer ring 1, a protective shell 3 is installed at one end of the outer ring 1, one side of the protective shell 3 is of arc-shaped design, when the cable passes through the pipeline, the protective shell 3 can reduce the friction on the cable, avoid the situation that the cable is broken and the protective film on its surface is greatly worn, one end of the inner ring 2 is slidably connected with a fixing ring 11, a sliding groove is provided on the fixing ring 11, a gear ring 4 is fixedly connected to the inner wall of the fixing ring 11, a handle 10 is installed on the outer side of the fixing ring 11, the handle 10 passes through the sliding groove on the fixing ring 11 and is fixedly connected to the gear ring 4, the handle 10 is slidably connected to the sliding groove of the fixing ring 11, the gear ring 4 and the handle 10 are used together with the fixing ring 11, the handle 10 can drive the gear ring 4 to rotate, a plurality of driven gears 5 are installed on the inner ring 2, the driven gears 5 are meshed with the gear ring 4, the driven gears 5 are distributed in a ring array with the center of the outer ring 1 as the midpoint, and the driven gears 5 are arranged in a ring array with the center of the outer ring 1 as the midpoint. The wheel 5 is used in conjunction with the gear ring 4, which can drive the driven gear 5 to rotate. The bottom of the driven gear 5 is fixedly connected to a bearing 6, and the surface of the bearing 6 is fixedly connected to the inside of the inner ring 2. Under this action, the friction of the driven gear 5 can be reduced when it rotates, thereby ensuring the smoothness of the rotation of the driven gear 5. A number of holes are evenly opened on the surface of the outer ring 1, and an adjusting mechanism 7 is installed on the top of the driven gear 5. The adjusting mechanism 7 and the driven gear 5 are used in conjunction with each other. The driven gear 5 can adjust the adjusting mechanism 7 according to pipes of different widths, so that the structure can be installed in pipes of different diameters. The operation is simple and the work efficiency is improved. A number of fixed shells 9 are fixedly connected to the inner wall of the inner ring 2, and a guide mechanism 8 is installed inside the fixed shell 9. The cable guide mechanism 8 of different thicknesses can adjust the corresponding width by itself, and it can be adjusted without the staff adjusting the distance. It can also guide the cable, thereby improving the work efficiency.
[0023] The adjusting mechanism 7 includes a ball screw 71, which is fixedly connected to the driven gear 5. The ball screw 71 and the driven gear 5 are used in conjunction with each other. The driven gear 5 can drive the ball screw 71 to rotate. The other end of the ball screw 71 passes through the hole of the outer ring 1 and is threadedly connected to a lifting block 72. A rubber ball 73 is installed on the top of the lifting block 72. The ball screw 71 and the lifting block 72 are used in conjunction with each other. When the driven gear 5 rotates, the position of the lifting block 72 is controlled by the ball screw 71 to be lifted and lowered. The rubber ball 73 on the lifting block 72 will squeeze the inside of the pipe, thereby increasing the friction force to support and fix the pipe.
[0024] The guide mechanism 8 includes a spring 81, which is fixedly connected to the inside of the fixed shell 9. The other end of the spring 81 is fixedly connected to a limit plate 82, which is slidably connected to the inner wall of the fixed shell 9. The diameter of the limit plate 82 is larger than the inner diameter of the opening of the fixed shell 9. Under this action, the limit plate 82 will not detach from the inside of the fixed shell 9. A fixed block 83 is fixedly connected to the surface of the limit plate 82. The spring 81, the limit plate 82 and the fixed block 83 are used in conjunction with each other. When the fixed block 83 is lifted up and down, the spring 81 will be expanded and squeezed, and the limit plate 82 will limit the spring 81. When the spring 81 is expanded to a certain extent, the limit plate 82 will be stuck at the top opening of the fixed shell 9. A ball seat 84 is installed on the top of the fixed block 83. When the cable passes through the middle of the wire passing structure, the ball seat 84 can assist the cable in passing the wire, making the wire passing smoother, and the guide mechanism 8 can also make the cable slide in the middle to avoid damage to the cable caused by large-area contact and wear with the pipeline.
[0025] Working principle: first adjust the adjustment mechanism 7 according to the width of the pipeline, first turn the handle 10 to drive the gear ring 4 to rotate, the driven gear 5 engages with the gear ring 4, and the driven gear 5 also starts to rotate. The lifting block 72 will rise or fall according to the rotation of the handle 10, thereby squeezing and fixing the inner wall of the pipeline. When the cable passes through the line, the guide mechanism 8 is automatically adjusted according to the thickness of the cable. When the cable passes through the middle of the passing structure, the ball seat 84 of the guide mechanism 8 is squeezed. When the fixed block 83 pushes the limit plate 82 to squeeze and move toward the inside of the fixed shell 9, it will also squeeze the spring 81, thereby achieving the effect of centering the cable and avoiding cable damage caused by large-area contact and wear between the cable and the pipeline.
