[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] Existing technologies often suffer from the problem of difficulty in fine-tuning the height of cable trays, thus reducing construction speed. This embodiment provides a dedicated support arm structure for cable trays. Please refer to [reference needed]. Figures 1-4 This cable tray support structure allows for adjustable installation height within a certain range, reducing construction costs and improving efficiency. It includes a mounting frame 1 and a fixing base 2. The fixing base 2's connecting end engages with a slot 34, facilitating quick assembly and disassembly. The mounting frame 1 is equipped with an adjusting installation mechanism 3 for height adjustment of the fixing base 2, while the fixing base 2 features a buffer limiting mechanism 4 to reduce installation pressure. The adjusting installation mechanism 3 allows for height adjustment within a certain range, improving cable tray installation efficiency, while the buffer limiting mechanism 4 reduces pressure during installation and limits the cable tray's position, enhancing installation stability.

[0028] Because the height of traditional cable tray supports is not adjustable, when the building structure is complex and the height of the cable tray needs to be finely adjusted, workers can only use tools to disassemble and reinstall the cable tray supports, which not only reduces construction efficiency but also increases construction costs. In order to solve the above problems... The adjustment and installation mechanism 3 includes a rotating rod 31 rotatably connected to the inside of the installation frame 1. A lifting seat 32 is threaded onto the rotating rod 31. Two sets of round rods 33 penetrating the lifting seat 32 are installed inside the installation frame 1. A slot 34 is provided on one side of the lifting seat 32. A compression spring 35 is connected to the top of the slot 34. A stop block 36 that is slidably connected to the slot 34 is installed at the bottom of the compression spring 35. Two sets of load-bearing plates 37 are installed on one side of the lifting seat 32. The top of the load-bearing plate 37 abuts against the bottom of the installed fixed seat 2. The load-bearing plate 37 provides support for the fixed seat 2. Two sets of inserts 38 are installed at the bottom of the fixed seat 2. The positions of the inserts 38 and the positioning rods 39 correspond to each other, making it easy for the positioning rods 39 to be inserted into the inserts 38. This allows for quick assembly and disassembly of the fixed seat 2. The two are symmetrically distributed below the fixed seat 2, improving the installation stability of the fixed seat 2. Two sets of positioning rods 39 that are adapted to the inside of the inserts 38 are installed on the lifting seat 32. Rotating the rotating rod 31 by the turntable at the top of the rotating rod 31, and supported by the round rod 33, causes the lifting seat 32 to move up and down on the outer wall of the rotating rod 31. This allows for adjustment of the installation height of the cable tray within a certain range, improving installation efficiency. Pulling the abutment block 36 upwards, under the elastic action of the compression spring 35, the connecting end of the fixed seat 2 is inserted into the slot 34. The abutment block 36 provides initial installation for the fixed seat 2. When the fixed seat 2 is inserted into the slot 34, the load-bearing plate 37 supports the bottom of the fixed seat 2, and the insertion cylinder 38 is connected to the positioning rod 39, thus enabling rapid installation of the fixed seat 2 and improving the installation speed of the cable tray.

[0029] Example 2

[0030] Based on Example 1, such as Figures 1-4 As shown, the existing technology makes it difficult to fine-tune the height of the cable tray, thus reducing the construction speed. However, when the cable tray sways, the traditional support arm is usually an integrated structure and does not have a certain buffer function, which can easily cause hard friction between the cable tray and the support arm, aggravate wear, and lead to the cable tray displacement and falling off. Therefore, this device is also equipped with a structure to reduce the pressure generated during installation.

[0031] When cable trays sway, traditional support arms often use an integrated rigid structure without their own cushioning design. This results in rigid contact between the cable tray and the support arm, and each sway exacerbates frictional wear. Over time, not only do the support arm and the cable tray suffer severe wear, but the cable tray also gradually loses its stable support due to frequent swaying and friction, making it prone to displacement or even detachment. To solve these problems, a buffer limiting mechanism 4 includes a buffer spring 41 connected inside the fixed base 2. Multiple sets of sliding rods 42 are installed inside the fixed base 2. A buffer seat 43 connected to the buffer spring 41 is slidably connected to the sliding rod 42. A buffer rod 44 is rotatably connected to the buffer seat 43. A placement seat 45 is rotatably mounted on the other end of the buffer rod 44. A limiting component for stabilizing the cable tray is provided on the placement seat 45. When the cable tray is installed on the placement seat 45, the cable tray generates downward pressure. With the rotation of both ends of the buffer rod 44, the buffer seat 43 is pressed and moved to one end under the support of the slide rod 42. Through the elastic action of the buffer spring 41, the pressure generated during installation can be reduced, thus improving the installation efficiency of the cable tray.

[0032] Traditional cable tray support arms lack a reasonable limiting structure. When the cable tray is subjected to external forces, it can easily exceed its normal displacement range, causing the cable tray to tilt or even collide with other objects, leading to safety accidents. To solve the above problems, a limiting component includes side rods 4011 installed on the side of the placement base 45. The side rods 4011 are symmetrically distributed on both sides of the limiting plate 4012, making the sliding of the limiting plate 4012 smoother. The limiting plate 4012 is slidably connected to the side rods 4011. The limiting plate 4012 is made of silicone, which increases the friction between the limiting plate 4012 and the cable tray, improving the limiting effect and protecting the cable tray. Multiple sets of connecting springs 4013 connected to the limiting plate 4012 are connected inside the placement base 45. After the cable tray is installed on the placement base 45, the elasticity of the connecting springs 4013 limits the side of the cable tray, improving its installation stability.
