[0002] Cable trays are critical infrastructure in modern electrical wiring systems. Their core function is to provide a safe, organized, flexible, and easily maintainable support and protection pathway for cables (power cables, control cables, communications cables, etc.). Stainless steel cable trays are widely used due to their corrosion resistance, high strength and rigidity, excellent fire resistance, good hygiene, and easy cleanability.

[0003] However, existing stainless steel cable trays have a simple structure and cannot flexibly adjust the internal space of the cable tray body according to the actual number of cables to be laid, resulting in low space utilization. Furthermore, during installation, it is difficult to flexibly adjust the deployment height of the entire cable tray, making it unable to meet the different usage requirements under different installation conditions. Therefore, we proposed an adjustable stainless steel cable tray to solve the above technical problems. Summary of the Invention

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] Example 1, reference Figure 1-5 An adjustable stainless steel cable tray comprises a tray cover 1, a ceiling connector 15 fixed to the ceiling by bolt fasteners, and a spatially adjustable tray main structure, wherein the interior of the ceiling connector 15 is a hollow structure; Specifically, the main structure of the spatially adjustable bridge includes two bridge side plates 2 slidably connected to the bridge cover plate 1, two telescopic slots 3 sequentially opened in the two bridge side plates 2, two adjustment plates 4 slidably connected in the two telescopic slots 3, and the same bridge bottom plate 5 welded to the bottom outer walls of the two adjustment plates 4; Furthermore, two lockers are symmetrically provided on the side walls of the two bridge side plates 2. The lockers include a hollow rod 6 fixedly connected to the side wall of the bridge side plate 2, a movable rod 7 slidably connected to the hollow rod 6, a threaded guide pin 8 welded to the side wall of the movable rod 7, a guide port 9 opened on one side of the hollow rod 6, and a butterfly locking nut 10 threadedly connected to the threaded guide pin 8. The bottom outer wall of the movable rod 7 is welded to the side wall of the bridge bottom plate 5. Furthermore, the outer wall of the threaded guide pin 8 is slidably connected to the inner wall of the guide opening 9, and the butterfly lock nut 10 is tightly fitted with the surface of the hollow rod 6. The bridge cover 1, the two bridge side plates 2 and the bridge bottom plate 5 are all made of stainless steel. The surface of the bridge cover 1 is provided with evenly distributed heat dissipation ports 11; Furthermore, an iron sheet 12 is fixedly connected to the outer wall of one side of the bridge cover 1, and the outer walls of one side of the two bridge side panels 2 are fixedly connected to the same blocking bar 13, and a magnet 14 adapted to the iron sheet 12 is fixedly embedded in the blocking bar 13. Then the bridge cover 1 can slide between the two bridge side panels 2, and after sliding into place, it will be blocked and limited by the blocking bar 13. At this time, the iron sheet 12 on the bridge cover 1 will be attracted by the magnet 14, which makes it easier to magnetically fix the bridge cover 1. Then, when the internal cables need to be inspected and maintained later, it is only necessary to pull the bridge cover 1 with force in sequence to separate the iron sheet 12 from the magnet 14. In this way, the installation method of the bridge cover 1 is designed to be magnetically attracted to replace the traditional screw fixing method, which can effectively improve the efficiency of disassembly and assembly of the bridge cover 1 during the inspection and maintenance process. Specific implementation method of this embodiment: By unscrewing the four butterfly locking nuts 10, the two adjustment plates 4 on the bridge base plate 5 can slide up and down in the two telescopic slots 3, which makes it easy to flexibly adjust the position of the bridge base plate 5, so that the accommodation space of the entire bridge body can be flexibly adjusted according to the actual number of cables laid, which is conducive to improving space utilization. This can avoid the waste caused by the bridge body space being too large, and the cable congestion caused by the bridge body space being too small. In the process of adjusting the bridge base plate 5 up and down, the four threaded guide pins 8 will slide up and down in the corresponding four guide ports 9. After the position adjustment of the bridge base plate 5 is completed, the position of the bridge base plate 5 is locked by the threaded locking cooperation of the four butterfly locking nuts 10 and the four threaded guide pins 8.

[0019] Example 2, reference Figure 1 and Figure 6-8 This embodiment is optimized based on the first embodiment, specifically: an adjustable stainless steel cable tray, further comprising a height adjustment structure, the height adjustment structure comprising an inverted U-shaped connecting seat 16, a fixed top plate 17 fixedly connected to the bottom outer wall of the ceiling connecting seat 15, two threaded lifting components and a synchronous control component; More specifically, the two threaded lifting assemblies each include a fixed square tube 18 fixedly connected to the bottom outer wall of the fixed top plate 17, a lifting screw 19 disposed in the fixed square tube 18, and a threaded lifting member 20 threadedly connected to the lifting screw 19; Furthermore, the bottom outer walls of the two threaded lifters 20 are fixedly connected to the top outer wall of the inverted U-shaped connecting seat 16, and the outer walls of the two threaded lifters 20 are slidably connected to the inner walls of the two fixed square tubes 18 respectively; Furthermore, the inverted U-shaped connecting seat 16 is fixedly connected between the two bridge side plates 2, and the upper parts of the two lifting screws 19 are connected to the inner wall of the fixed top plate 17 through bearings; More specifically, the synchronous control assembly is located in the ceiling connection base 15, and the synchronous control assembly includes a transmission shaft 21 rotatably mounted in the ceiling connection base 15, two worms 22 fixedly mounted on the transmission shaft 21 in sequence, and two worm wheels 23 fixedly mounted on the top ends of the two lifting screws 19 in sequence; Furthermore, the two worms 22 are respectively engaged with the two worm wheels 23. A handwheel 24 is fixedly connected to the outer wall of one end of the transmission shaft 21. The handwheel 24 facilitates manual control of the rotation of the two worms 22 on the transmission shaft 21. The self-locking performance of the worms 22 and the worm wheels 23 after engagement can ensure the stability of the lifting and lowering adjustment action. The specific implementation method of this embodiment: First, the two worm gears 22 on the transmission shaft 21 can be driven to rotate through the handwheel 24, and then the two worm wheels 23 engaged with the two worm gears 22 will drive the two lifting screws 19 to rotate synchronously, and then the forward and reverse rotation of the external handwheel 24 can control the synchronous forward and reverse rotation of the two lifting screws 19; secondly, under the connection effect of the inverted U-shaped connecting seat 16, the two threaded lifting parts 20 threadedly connected to the two lifting screws 19 will synchronously drive the entire bridge to perform lifting and lowering movements, thereby facilitating the flexible adjustment of the deployment height of the entire bridge, which can meet the usage requirements in different situations at the installation site, better adapt to the complex installation environment on site, and improve the adaptability and flexibility of the entire bridge installation.
