Description

Technical Field

[0001] This utility model relates to the field of building electrical engineering technology, and in particular to a cable tray bracket. Background Technology

[0002] Cable trays are essential devices for supporting and laying cables. As a crucial component of power and communication systems, they play an indispensable role in engineering construction and system operation. In terms of safety, cable trays provide reliable protection; the metal material of the trays can withstand mechanical impacts and rodent / insect damage, significantly reducing the cable failure rate. From an engineering implementation and maintenance perspective, cable trays offer significant convenience. Their modular design allows for rapid assembly of standard components, greatly improving construction efficiency.

[0003] Cable trays are designed to support, protect, and manage cables, achieving efficient operation through a systematic design. They are fixed to the building structure using supports such as columns and hangers, utilizing the tray's own strength and reasonable support spacing to bear the weight of the cables and ensure mechanical stability. Simultaneously, the combination of straight lines, bends, and tees in the tray's structure enforces standardized cable routing, enabling layered and categorized laying, avoiding cross-linking and minimizing interference between high-voltage and low-voltage cables.

[0004] In existing technologies, some cable tray brackets are directly anchored to the building structure using bolted columns, hangers, or expansion bolts. Once installed, height adjustment requires disassembly and re-drilling, which is complicated, inefficient, and poses a high risk of working at height. Therefore, a new type of cable tray bracket is proposed to solve these problems. Utility Model Content

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, when adjusting the height of the cable tray, pressing the control lever compresses the spring, pushing the rotating rod to disengage the locking rod from the adjusting sleeve, thus allowing for flexible height adjustment on the column. Releasing the control lever resets the spring, causing the locking rod to relock. This design utilizes the principles of springs and levers to achieve free height adjustment and automatic locking, requiring no tools, providing strong stability, and suitable for complex working conditions.

[0024] 2. In this utility model, when installing the cable tray, the cable tray seat is placed on the outer wall of the limiting sleeve and positioned on top of the fixing ring. Releasing the control button compresses the spring, causing it to return and push the sliding column, allowing the limiting ball to fall into the slot. After pushing the limiting sleeve into the adjusting sleeve, releasing the button allows the spring to return and lock the ball in place. For disassembly, pressing the button returns the ball to its slot for removal. This design utilizes the linkage between the spring and the limiting mechanism, requiring no tools and allowing for quick assembly and disassembly by a single person, greatly facilitating maintenance and reducing time and labor costs.

A fixed shaft 9 is rotatably connected to the inner wall of the rotating rod 7. The fixed shaft 9 is used to support the rotating rod 7. Fixed rods 10 are fixedly connected to both ends of the fixed shaft 9. The fixed rods 10 are used to fix the fixed shaft 9.

[0033] A locking rod 8 is fixedly connected to the inner wall of the rotating rod 7. The locking rod 8 is used to lock the adjusting sleeve 1 and the column 2. An installation component is installed at the bottom of the adjusting sleeve 1 for easy installation. The bottom of the adjusting sleeve 1 is fixedly connected to a cable tray seat 3, which is used to install a cable rack 4. The inner wall of the cable tray seat 3 is fixedly connected to a cable rack 4, which is used to store cables. The inner wall of the cable rack 4 is threadedly connected to a fixing screw 17, which is used to connect the cable tray seat 3 and the cable rack 4. The outer wall of the fixing screw 17 is threadedly connected to the inner wall of the cable tray seat 3. The outer wall of the locking rod 8 is slidably connected to the inner wall of the column 2. The outer wall of the locking rod 8 is slidably connected to the inner wall of the adjusting sleeve 1. An elastic spring 6 is sleeved on the outside of the control rod 5. The elastic potential energy of the elastic spring 6 causes the control rod 5 to reset. The outer wall of the fixing rod 10 is fixedly connected to the inner wall of the adjusting sleeve 1. The outer wall of the elastic spring 6 is slidably connected to the inner wall of the adjusting sleeve 1. The outer wall of the control rod 5 is slidably connected to the inner wall of the column 2. The outer wall of 10 is slidably connected to the inner wall of 2.

[0034] Reference Figures 2 to 4 The installation assembly includes a limiting sleeve 12, which limits the limiting ball 13. The limiting sleeve 12 is slidably connected to the inner wall of the adjusting sleeve 1. A fixing ring 11 is fixedly connected to the outer wall of the limiting sleeve 12 to prevent the cable tray seat 3 from falling off. A control button 16 is slidably connected to the inner wall of the limiting sleeve 12 to push the sliding column 14. The top of the control button 16 is fixedly connected to the sliding column 14, which pushes the limiting ball. 13. A compression spring 15 is sleeved on the outside of the sliding column 14. The elastic potential energy of the compression spring 15 resets the control button 16. A limit ball 13 is slidably connected to the outer wall of the sliding column 14. The limit ball 13 is used to lock the adjusting sleeve 1 and the limit sleeve 12. The outer wall of the limit ball 13 is detachably connected to the inner wall of the limit sleeve 12. The top of the compression spring 15 is fixedly connected to the inside of the limit sleeve 12, and the bottom of the compression spring 15 is fixedly connected to the top of the control button 16.

[0035] Working Principle: When the height of the cable tray needs to be adjusted, press the control lever 5. The control lever 5 compresses the spring 6 and pushes the bottom of the rotating rod 7. The middle of the rotating rod 7 is rotatably connected to the fixed shaft 9, and both ends of the fixed shaft 9 are fixedly connected to the inner wall of the fixed rod 10. Therefore, under the pushing force of the control lever 5, the bottom of the rotating rod 7 pries the top. The movement of the rotating rod 7 drives the locking lever 8, disengaging it from the adjusting sleeve 1. At this time, the adjusting sleeve 1 can be adjusted to the appropriate height on the column 2. After releasing the control lever 5, the spring 6 uses its elastic potential energy to reset the control lever 5, and the locking lever 8 slides into the column 2 and the adjusting sleeve 1, re-locking and preventing relative movement between the adjusting sleeve 1 and the column 2. Thus, the height adjustment is complete and fixed. This design achieves automatic height locking through the principles of springs and levers, is easy to operate without tools, has strong stability, and is suitable for complex working conditions.

[0036] When installing the cable tray, place the cable tray base 3 onto the outer wall of the limiting sleeve 12 and position it on top of the fixing ring 11. Then press the control button 16 to compress the compression spring 15 and push the sliding column 14 upward, causing the limiting ball 13 to fall into the slot on the outer wall of the sliding column 14. At this time, push the limiting sleeve 12 into the inner wall of the adjusting sleeve 1, and then stop pressing the control button 16. The elastic potential energy of the compression spring 15 resets the control button 16, and the limiting ball 13 is pushed back into the inner wall of the limiting sleeve 12, locking between the adjusting sleeve 1 and the limiting sleeve 12 for a secure lock. To disassemble the cable tray, press the control button 16 again to return the limiting ball 13 to the slot of the sliding column 14, and the limiting sleeve 12 and the cable tray base 3 can be easily removed. This design, through the linkage of the spring and the limiting structure, allows the disassembly operation to be completed quickly by a single person without additional tools, significantly reducing the manpower and time costs of equipment maintenance.
