[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, a multi-pulley linkage type cable fast laying positioning bracket includes: a base frame 20, the base frame 20 being a tube with a U-shaped cross section, the opening of the base frame 20 facing downwards, and multiple identical threaded holes evenly provided on each side of the base frame 20.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a pulley structure is installed on the top of the base frame 20 to control cable tension. The pulley structure includes: a front frame 31, a front pulley assembly 32, a rear frame 34, and a rear pulley assembly 35. The front frame 31 is slidably installed on the top of the base frame 20, the front pulley assembly 32 is rotatably connected to the wall of the front frame 31, the rear frame 34 is slidably installed on the top of the base frame 20, and the rear pulley assembly 35 is rotatably connected to the side wall of the rear frame 34. The walls of the rear pulley assembly 35 and the front pulley assembly 32 can contact the cable.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the front frame 31 is an L-shaped plate, and the front pulley assembly 32 is rotatably connected to the corner of the side wall of the front frame 31. The front pulley assembly 32 is horizontally placed on the top of the base frame 20. The rear frame 34 is a semi-capsule-shaped plate, and the rear pulley assembly 35 is also horizontally placed above the base frame 20. The rear pulley assembly 35 is parallel to the front pulley assembly 32, and the horizontal plane of the rear pulley assembly 35 is higher than that of the front pulley assembly 32. The pulley structure also includes a front rod 30, a rear rod 33, a joint 36, a limiting plate 37, and a limiting block 38. The front rod 30 is slidably connected to the top of the base frame 20, the front frame 31 is fixedly connected to the front end of the front rod 30, the rear rod 33 is also slidably connected to the top of the base frame 20, the rear frame 34 is fixedly connected to the side wall of the rear rod 33, the joint 36 is fixedly connected to the side wall of the rear pulley assembly 35, the limiting plate 37 is sleeved on the side wall of the joint 36, and the limiting block 38 is fixedly connected to the rear rod 33. On the side wall of the base frame 20, the front rod 30 is T-shaped and the rear rod 33 is L-shaped. Two rear rods 33 are symmetrically arranged on the top of the base frame 20. There is a gap between the symmetrical rear rods 33. The front rod 30 can pass through the gap between the symmetrical rear rods 33. The rear frame 34 is located on the side wall of one of the rear rods 33. The limiting block 38 is located on the side wall of the other rear rod 33. The joint 36 is bolt-shaped. The wall of the limiting plate 37 is provided with a circular groove for the fitting joint 36. The bottom of the limiting plate 37 is provided with an opening for the fitting limiting block 38. The limiting plate 37 is capsule-shaped. The wall of the base frame 20 is also provided with a linkage structure, which includes: a fixed plate 21, a screw 22 and an adjusting plate 23. The fixed plate 21 is symmetrically fixedly connected to the opening at the bottom of the base frame 20. The screw 22 is rotatably connected between the symmetrical fixed plates 21. The adjusting plate 23 is symmetrically arranged on the wall of the screw 22.

[0030] In practical use, the base frame 20 is first installed in the required position through the threaded holes on the wall of the base frame 20. After the base frame 20 is installed, the cable can be passed under the front pulley group 32 and locked on the wall of the front pulley group 32. Then, the cable can be passed over the rear pulley group 35 and locked on the wall of the rear pulley group 35. If the cable is too loose and cannot fit the front pulley group 32 and the rear pulley group 35, the handle on the wall of the screw 22 is turned to drive the screw 22 to rotate. As the screw 22 rotates, the symmetrical front rod 30 will gradually separate from the other. As the front rod 30 moves, it will drive the corresponding front rod 30, front frame 31, rear rod 33 and rear frame 34 to move. At the same time, the rear pulley group 35 and the front pulley group 32 will move closer to each other. At this time, the walls of the front pulley group 32 and the rear pulley group 35 will tighten the cable to make the cable taut.

[0031] In summary, by setting up a pulley structure, the cables on the device can be tightened by adjusting the positions of the rear pulley group 35 and the front pulley group 32, without rework or reinstallation, thus saving a lot of time and effort.

[0032] like Figure 2 and Figure 4As shown, the fixed plate 21 is a rectangular plate, and each fixed plate 21 has a circular slot on its wall that is adapted to the size of the screw 22. The screw 22 has handles installed at its front and rear ends. The base frame 20 has a rectangular slot on its top that is adapted to the sliding of the adjustment plate 23. The screw 22 is cylindrical, and the arc surface of the screw 22 has opposing threads. The screw 22 can pass through the wall of the symmetrical adjustment plate 23 and be threaded to each adjustment plate 23. The top of one adjustment plate 23 can be fixedly connected to the bottom of the front rod 30, and the top of the other adjustment plate 23 can be fixedly connected to the bottom of the symmetrical rear rod 33.

[0033] In actual use, the rear rod 33 and the front rod 30 will always be in contact with the top of the base frame 20 when they move;

[0034] In summary, by setting the front pulley group 32 to pass under the rear pulley group 35, this solution can tighten a wider range of loose cables.

[0035] Working principle: The base frame 20 is installed in the required position through the threaded holes on the wall of the base frame 20. After the base frame 20 is installed, the cable can be passed under the front pulley group 32 and locked on the wall of the front pulley group 32. Then the cable can be passed over the rear pulley group 35 and locked on the wall of the rear pulley group 35. If the cable is too loose and cannot fit the front pulley group 32 and the rear pulley group 35, the handle on the wall of the screw 22 is turned to drive the screw 22 to rotate. As the screw 22 rotates, the symmetrical front rod 30 will gradually separate from the other. As the front rod 30 moves, it will drive the corresponding front rod 30, front frame 31, rear rod 33 and rear frame 34 to move. At the same time, the rear pulley group 35 and the front pulley group 32 will move closer to each other. At this time, the walls of the front pulley group 32 and the rear pulley group 35 will tighten the cable to make the cable taut.
