[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 4 As shown in the figure, a tunnel wall cable quick-installation bracket according to an embodiment of the present invention includes a mounting frame 1; a quick-release assembly is provided on the side wall of the mounting frame 1; a cable guide assembly is provided on the top of the mounting frame 1; a locking assembly is provided on the mounting frame 1 through the cable guide assembly; and an anti-detachment assembly is provided on the mounting frame 1 through the cable guide assembly. In operation, the quick-release assembly is a split structure. First, the quick-release assembly is installed on the wall, and then the mounting frame 1 is installed on the wall through the quick-release assembly. The cable is placed in the cable guide assembly on the top of the mounting frame 1. The gap between the cable guide assemblies is adjusted according to the situation, and then the locking assembly is used to lock and fix the cable guide assembly. The anti-detachment assembly limits the cable on the top of the mounting frame 1. This step, which fixes the mounting frame 1 to the tunnel wall through the quick-release assembly, forms a quick-installation structure for the mounting frame 1, realizing the function of quick installation and removal of the mounting frame 1. It solves the problem that the entire mounting frame 1 needs to be removed from the wall when it is damaged and replaced, simplifies the operation steps, improves the reusability of parts, reduces the steps of repositioning and drilling, and improves the adjustability of the device.

[0025] like Figure 1 and Figure 2As shown, the quick-release assembly includes a fixing block 11, an expansion screw 12, a hook 13, a first fixing bracket 14, a fixing pin 15, a first spring 16, and a pull plate 17. Multiple sets of fixing blocks 11 are symmetrically arranged on the side wall of the mounting bracket 1. The fixing blocks 11 are fixed to the wall by the expansion screws 12. The hooks 13 are fixedly connected to the side wall of the fixing blocks 11 away from the expansion screws 12. A slot is provided in the middle of the mounting bracket 1. The hooks 13 engage with the mounting bracket 1 through the slot in the middle of the mounting bracket 1. The first fixing bracket 14... A fixing pin 15 is slidably connected to the side wall of the mounting bracket 1 away from the fixing block 11; a positioning hole is provided in the middle of the first fixing bracket 14; a first spring 16 is sleeved on the outer side wall of the fixing pin 15 away from the hook 13; a pull plate 17 is fixedly connected to the end of the fixing pin 15 away from the hook 13; the fixing pin 15 is inserted into the positioning hole in the middle of the hook 13 and the mounting bracket 1; an anti-slip component is provided on the side wall of the pull plate 17 near the fixing pin 15; a support assembly is provided on the side wall of the first fixing bracket 14. In operation, the fixing block 11 and the mounting bracket 1 are separate structures. First, the fixing block 11 is installed on the tunnel wall using expansion screws 12. Then, the mounting bracket 1 is hung on the hook 13. Before the mounting bracket 1 is hung on the hook 13, the support assembly is used to lift the pull plate 17, and the first spring 16 is stretched, causing the fixing pin 15 to move away from the mounting bracket 1. After the hook 13 is fixed to the mounting bracket 1 through the slot in the middle of the mounting bracket 1, the pull plate 17 is released. The first spring 16 drives the fixing pin 15 and the pull plate 17 to move closer to the mounting bracket 1. The fixing pin 15 is inserted into the positioning hole of the hook 13 and the mounting bracket 1, fixing the hook 13 and the mounting bracket 1 together. This step, which fixes the hook 13 and the mounting bracket 1 by inserting the fixing pin 15 into the positioning hole in the middle of the hook 13 and the mounting bracket 1, forms a quick-release structure for the mounting bracket 1, realizing the function of fixing the mounting bracket 1 to the tunnel wall. The separate fixing structure solves the problem of needing to remove the entire mounting bracket 1 when replacing it, improves the reusability of parts, and increases the speed of replacing the mounting bracket 1.

[0026] like Figure 1 , Figure 3 and Figure 4As shown, the guide assembly includes a second fixed frame 2, a slider 21, a fixed shaft 22, and rollers 23. The second fixed frame 2 is fixedly connected to the top of the mounting frame 1. The slider 21 is slidably connected to the middle of the second fixed frame 2. Multiple sets of sliders 21 are arranged in the middle of the second fixed frame 2 and are evenly distributed in the middle of the second fixed frame 2. The fixed shaft 22 is fixedly connected to the top of the slider 21. The rollers 23 are rotatably connected to the outer wall of the fixed shaft 22. During operation, the slider 21 is slid to a suitable position as required, and the cable is placed between the rollers 23 on the top of the second fixed frame 2. When the cable moves on the top of the second fixed frame 2, the rollers 23 convert the static friction between the cable and the fixed shaft 22 into rolling friction. This step guides the cable through the slidable rollers 23, forming a cable guide structure. It realizes the function of limiting and guiding the cable, solves the problem of inconvenient adjustment of the gap between the rollers 23 when the cable is placed on the top of the second fixed frame 2, and improves the adjustability of the device.

[0027] like Figure 3 and Figure 4 As shown, the locking assembly includes a guide rod 3, a second spring 31, a fixed plate 32, anti-slip teeth 33, a silicone plate 34, and a pressing block 35. The guide rod 3 is slidably connected to the middle of the fixed shaft 22. The fixed plate 32 is fixedly connected to the bottom end of the guide rod 3. The second spring 31 is sleeved on the outer side wall of the guide rod 3 away from the fixed plate 32. The anti-slip teeth 33 are fixedly connected to the top of the fixed plate 32. Multiple sets of anti-slip teeth 33 are evenly distributed on the top of the fixed plate 32. The silicone plate 34 is fixedly connected to the top of the inner side wall of the second fixed frame 2. A pair of silicone plates 34 are symmetrically arranged on the top of the inner side wall of the second fixed frame 2. The pressing block 35 is fixedly connected to the top of the guide rod 3. During operation, pressing the pressing block 35 presses the guide rod 3 downward. When the second spring 31 is compressed, the fixed plate 32 disengages from the silicone plate 34, and the slider 21 slides to a suitable position. Then, the pressing block 35 is released, and the second spring 31 drives the pressing block 35, the guide rod 3, and the fixed plate 32 to move upward. The anti-slip teeth 33 contact the silicone plate 34 and are locked at the bottom of the inner side wall of the second fixed frame 2, fixing the slider 21 and the roller 23 in a certain position. In this step, the anti-slip teeth 33 lock the silicone plate 34 to fix the slider 21 and the roller 23, forming a locking and fixing structure for the roller 23. This realizes the function of locking and fixing the roller 23 after adjusting its position, solving the problem of the slider 21 shifting after being fixed in the middle of the second fixed frame 2, and improving the convenience of moving and fixing the slider 21.

[0028] like Figure 1 and Figure 2As shown, the support assembly includes a support arm 4 and a pad 41. The support arm 4 is hinged to the side wall of the first fixed frame 14 near the pull plate 17. A pair of support arms 4 are provided on the side wall of the first fixed frame 14 and are arranged symmetrically. The pad 41 is fixedly connected to the end of the support arm 4 away from the first fixed frame 14. In operation, before the mounting frame 1 is installed on the side wall of the fixed block 11, the support arm 4 is rotated to pull the pull plate 17 outward, so that the pad 41 contacts the pull plate 17 and supports and fixes the pull plate 17. After the hook 13 is inserted into the middle of the mounting frame 1, the support arm 4 and the pad 41 are rotated to one side, thereby releasing the pull plate 17. This step, by supporting the pull plate 17 with the support arm 4 and the pad 41, forms a support structure for the pull plate 17, which realizes the function of supporting the pull plate 17 to move the fixing pin 15 away from the mounting frame 1 and improves the convenience of inserting the hook 13 into the middle of the mounting frame 1.

[0029] like Figure 1 As shown, the anti-detachment component includes a limiting rope 5; both ends of the limiting rope 5 are detachably installed on the top of the second fixing frame 2; during operation, after the cable is placed on the top of the second fixing frame 2, the limiting rope 5 is installed on the top of the second fixing frame 2 to restrict the cable on the top of the second fixing frame 2; this step, by setting the cable to be bound by the limiting rope 5, forms a cable anti-detachment structure, improves the stability of the cable when placed on the top of the second fixing frame 2, and reduces the possibility of the cable falling off the top of the second fixing frame 2.

[0030] like Figure 2 As shown, the anti-slip component includes a silicone pad 6; the silicone pad 6 is fixedly connected to the side wall of the pull plate 17 near the fixing pin 15; a pair of silicone pads 6 are provided on the side wall of the pull plate 17 and are arranged symmetrically; during operation, when the pull plate 17 is pulled, the hand comes into contact with the silicone pad 6, increasing the friction between the pull plate 17 and the hand, and reducing the slippage that occurs when the pull plate 17 is pulled.

[0031] During operation, the quick-release assembly is a split structure. First, the quick-release assembly is installed on the wall, and then the mounting bracket 1 is installed on the wall via the quick-release assembly. The cable is placed in the cable guide assembly at the top of the mounting bracket 1. The gap between the cable guide assemblies is adjusted as needed, and then the locking assembly is used to lock and fix the cable guide assembly. The anti-detachment assembly limits the cable at the top of the mounting bracket 1. The fixing block 11 and the mounting bracket 1 are also split structures. First, the fixing block 11 is installed on the tunnel wall using expansion screws 12, and then the mounting bracket 1 is installed on the wall via the quick-release assembly. Before mounting bracket 1 is hung on hook 13, the support assembly is used to lift pull plate 17, stretching the first spring 16 and moving the fixing pin 15 away from mounting bracket 1. After hook 13 is fixed to mounting bracket 1 through the slot in the middle of mounting bracket 1, pull plate 17 is released. The first spring 16 drives the fixing pin 15 and pull plate 17 closer to mounting bracket 1. The fixing pin 15 is inserted into the positioning hole of hook 13 and mounting bracket 1, fixing hook 13 and mounting bracket 1 together; press press block 35. Pressing the guide rod 3 downwards compresses the second spring 31, causing the fixed plate 32 to detach from the silicone plate 34. The slider 21 slides to a suitable position, and the pressing block 35 is released. The second spring 31 then moves the pressing block 35, guide rod 3, and fixed plate 32 upwards. The anti-slip teeth 33 contact the silicone plate 34 and engage with the bottom of the inner wall of the second fixing frame 2, fixing the slider 21 and roller 23 in a specific position. The mounting bracket 1 is installed in front of the side wall of the fixing block 11. First, rotate the support arm 4 to pull the plate 17. Pull outwards to make pad 41 contact the pull plate 17, supporting and fixing the pull plate 17. After the hook 13 is inserted into the middle of the mounting bracket 1, rotate the support arm 4 and pad 41 to one side to release the pull plate 17. After the cable is placed on the top of the second fixing bracket 2, install the limiting rope 5 on the top of the second fixing bracket 2 and restrict the cable on the top of the second fixing bracket 2. When pulling the pull plate 17, the hand contacts the silicone pad 6, increasing the friction between the pull plate 17 and the hand and reducing slippage when pulling the pull plate 17.
