Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, and in particular to a spliced ​​galvanized assembled cable tray. Background Technology

[0002] In cable laying projects, cable trays serve as crucial equipment for supporting and protecting cables. Their ease of installation, structural stability, and corrosion resistance are essential for the safe operation of the entire electrical system. However, existing cable trays often suffer from complex installation and difficult disassembly, and some structures are prone to corrosion after long-term use, affecting their service life.

[0003] In the prior art, Chinese patent document CN220341956U discloses a hot-dip galvanized cable tray. It features a trapezoidal cable tray and a fixing plate. The top of the trapezoidal cable tray has a sliding cover, and L-shaped sliders are symmetrically fixed to one side of the bottom of the sliding cover. A first slot is symmetrically arranged on one side of the interior of the trapezoidal cable tray, and a second slot is arranged at the lower end of the same side. A first locking block is symmetrically fixed to the other side of the trapezoidal cable tray, and a second locking block is fixed to the lower end of the other side. The trapezoidal cable tray has a slot at one end and a locking block at the other, allowing multiple trapezoidal cable trays to be bridged. Its modular design facilitates transportation, and the snap-fit ​​assembly method facilitates assembly and disassembly, reducing labor costs. The second cable tray is connected via a snap-fit ​​mechanism. The cable tray is fixed inside the trapezoidal cable tray using a double-layer bracket design, which greatly improves the applicability of the cable. The clamping plate fixes the cable without damaging it. Although the split design and snap-fit ​​connection make assembly convenient, the connection structure relies on the direct snap-fit ​​of the clip and the slot, lacking a locking mechanism, and is prone to loosening under frequent vibration or disassembly. At the same time, its fixing method is only achieved through the clamping plate, which does not fully consider the compatibility of different specifications of cables and the heat dissipation requirements. However, consistent with conventional technology, the installation of integrated cable trays cannot adapt to the problem of space size limitations, and the cables are prone to overheating and performance degradation under high load operation, resulting in poor practicality. Therefore, this utility model discloses a spliced ​​galvanized assembled cable tray to solve the problems of poor heat dissipation performance, single fixing method and poor site adaptability of traditional cable trays. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a spliced ​​galvanized cable tray to solve the problems of poor heat dissipation performance, single fixing method and poor site adaptability of traditional cable trays.

A positioning pin is slidably inserted into the mounting groove. A handle is mounted on the top of the positioning pin, and a vertical spring is sleeved on the positioning pin. A limit ring is fixedly installed on the positioning pin near the positioning groove.

[0007] Preferably, the two L-shaped connectors are fixedly installed on the side wall of the first cable tray by screws, and the length and width dimensions of the positioning groove are the same as the length and width dimensions of the L-shaped connector.

[0008] Preferably, the diameter of the positioning pin is the same as the diameter of the circular hole on the L-shaped connector, and the diameter of the mounting groove is the same as the diameter of the limiting ring.

[0009] Preferably, one end of the vertical spring is abutted against the inner wall of the top of the mounting groove, and the other end of the vertical spring is mounted on the upper end face of the limiting ring.

[0010] Preferably, the fixing component includes two lower mounting blocks, which are respectively mounted on the bottom walls of the first cable tray and the second cable tray. An upper mounting block is mounted directly above the lower mounting blocks. Multiple sets of guide blocks are mounted on both sides of the lower end of the upper mounting block.

The side walls of the first cable tray and the second cable tray have mounting grooves on the upper side of the top of the upper mounting block. A fixing block is slidably mounted in the mounting groove. The upper end face of the fixing block protruding from the side wall of the first cable tray and the second cable tray is inclined. A horizontal guide rod is mounted on the end of the fixing block near the mounting groove. A horizontal spring is sleeved on the horizontal guide rod.

[0011] Preferably, the lower mounting block and the upper mounting block have multiple sets of fixing grooves on their opposite sidewalls, and each set of fixing grooves has multiple sets of heat dissipation holes on its bottom wall.

[0012] Preferably, both ends of the lower mounting block and the upper mounting block are provided with heat dissipation ventilation channels located below the fixing groove, and the side wall of the heat dissipation ventilation channel near the fixing groove is connected to multiple sets of heat dissipation holes.

[0025] This utility model provides, for example Figures 1 to 5The illustrated splicing galvanized cable tray includes: a first cable tray 1, which is U-shaped; a second cable tray 5 on one side of the first cable tray 1; a cover plate 2 installed above the first cable tray 1 and the cover plate 2; and grooves 14 opened on both side walls of the first cable tray 1 and the second cable tray 5 corresponding to the positions of the cover plate 2, with the cover plate 2 slidably installed in the grooves 14; and handles 3 installed at one end of each cover plate 2; connecting components are provided on the adjacent side walls of the first cable tray 1 and the second cable tray 5 to connect the first cable tray 1 and the second cable tray 5 together; and fixing components are installed in both the first cable tray 1 and the second cable tray 5 to fix the cables. Through the spring self-locking structure design of the L-shaped connector 4 and the positioning pin 13, the first cable tray 1 and the second cable tray 5 are quickly connected and firmly fixed, avoiding the defects of traditional snap-fit ​​structures that are prone to loosening under long-term vibration or frequent disassembly, and significantly improving the reliability of equipment operation. Multiple sets of heat dissipation holes 10 and heat dissipation ventilation channels 9 in the fixed components form an efficient heat dissipation channel. Combined with the double-layer structure of the upper and lower mounting blocks 6, this effectively reduces the operating temperature of the cable under high load, improving equipment stability and lifespan. The design of multiple guide blocks 11 and fixing grooves 8 supports rapid adjustment and fixing of cables of different specifications, adapting to complex scenarios without replacing components. Meanwhile, the inclined fixing blocks 15 reduce installation resistance and improve operational convenience. The sliding cover 2 can be opened with one hand via the handle 3, facilitating cable inspection and replacement. The modular design supports rapid replacement in case of partial damage, reducing maintenance costs and downtime. The synergistic effect of the galvanized layer and heat dissipation design reduces the risk of corrosion and overheating. Combined with a robust connection structure, this comprehensively improves the durability and service life of the equipment.

[0026] Furthermore, in this example, such as Figure 1 and Figure 5As shown, the connecting assembly includes two L-shaped connectors 4, which are installed on the side wall of the first cable tray 1 near the second cable tray 5. A through-hole is formed at one end of each L-shaped connector 4 near the second cable tray 5. A positioning groove 12 is formed on the second cable tray 5 vertically corresponding to the position of the L-shaped connector 4. Mounting grooves 19 are formed on the top of both sides of the second cable tray 5, with the bottom of the mounting grooves 19 perpendicularly intersecting the positioning grooves 12. A positioning pin 13 is slidably inserted into the mounting groove 19. A handle 16 is installed on the top of the positioning pin 13, and a vertical spring 18 is sleeved on the positioning pin 13. A position on the positioning pin 13 near the positioning groove 12... A limiting ring 20 is fixedly installed. Two L-shaped connectors 4 are fixedly installed on the side wall of the first cable tray 1 by screws. The length and width dimensions of the positioning groove 12 are the same as those of the L-shaped connectors 4. The diameter of the positioning pin 13 is the same as the diameter of the circular hole on the L-shaped connector 4, and the diameter of the mounting groove 19 is the same as the diameter of the limiting ring 20. One end of the vertical spring 18 abuts against the inner wall of the top of the mounting groove 19, and the other end of the vertical spring 18 is installed on the upper end face of the limiting ring 20. The two L-shaped connectors 4 are fixedly installed on the side wall of the first cable tray 1 by screws, and a through circular hole is provided at the end near the second cable tray 5. When the first cable tray 1 and the second cable tray 5 are connected, the end of the L-shaped connector 4 is embedded in the positioning groove 12 on the side wall of the second cable tray 5 to achieve initial positioning. The length and width dimensions of the positioning groove 12 are perfectly matched with the L-shaped connectors 4 to ensure the connection accuracy. The second cable tray 5 has a mounting groove 19 at its top, the bottom of which intersects perpendicularly with the positioning groove 12. A positioning pin 13 is slidably inserted into the mounting groove 19, the diameter of which is the same as the size of the circular hole in the L-shaped connector 4. Under the elastic force of the vertical spring 18, the positioning pin 13 extends downward and passes through the circular hole in the L-shaped connector 4, forming a self-locking mechanism. The spring pressure presses the positioning pin 13 into the circular hole in the L-shaped connector 4, preventing the cable tray from separating. By pulling the handle 16 at the top of the positioning pin 13, the spring pressure is overcome, causing the positioning pin 13 to retract into the mounting groove 19, thus releasing the lock. The limiting ring 20 restricts the pop-out height of the positioning pin 13, ensuring operational stability. Quick connection and disassembly can be achieved without tools, and the spring self-locking mechanism remains stable even under vibration, solving the problem of easy loosening in traditional locking structures.

[0027] Furthermore, in this example, such as Figure 3 and Figure 4As shown, the fixing assembly includes two lower mounting blocks 6, which are respectively mounted on the bottom walls of the first cable tray 1 and the second cable tray 5. An upper mounting block 7 is mounted directly above the lower mounting blocks 6. Multiple sets of guide blocks 11 are mounted on both sides of the lower end of the upper mounting block 7. A groove of the same size as the guide block 11 is formed on the lower mounting block 6 corresponding to the position of each set of guide blocks 11. A mounting groove 17 is formed on the side wall of the first cable tray 1 and the second cable tray 5 above the top of the upper mounting block 7. A fixing block 15 is slidably mounted in the mounting groove 17. The fixing block 15 protrudes from the upper end face of one end of the side wall of the first cable tray 1 and the second cable tray 5 in an inclined shape. A horizontal guide rod 21 is installed at one end of the fixing block 15 near the mounting groove 17. A horizontal spring 22 is fitted onto the horizontal guide rod 21. Multiple sets of fixing grooves 8 are formed on the opposite side walls of the lower mounting block 6 and the upper mounting block 7. Multiple sets of heat dissipation holes 10 are formed on the bottom wall of each fixing groove 8. Heat dissipation ventilation channels 9 are formed on the side walls of the lower mounting block 6 and the upper mounting block 7 below the fixing grooves 8. The side wall of the heat dissipation ventilation channel 9 near the fixing groove 8 is connected to the multiple sets of heat dissipation holes 10. The lower mounting block 6 is fixed to the bottom wall of the cable tray. The upper mounting block 7 slides vertically through the guide block 11 and engages with the groove of the lower mounting block 6. The cable is placed in the fixing groove 8 of the lower mounting block 6. The cable is pressed by sliding the upper mounting block 7. The inclined design of the fixing block 15 reduces the installation resistance. The horizontal guide rod 21 and the horizontal spring 22 ensure that the fixing block 15 automatically resets, simplifying the operation. Multiple sets of heat dissipation holes 10 are provided on the bottom wall of each fixing groove 8 to increase the air contact area. The side walls of the lower mounting block 6 and the upper mounting block 7 are provided with heat dissipation ventilation channels 9, which communicate with the heat dissipation circular holes 10 to form a convection path. The layered design of the lower mounting block 6 and the upper mounting block 7 expands the heat dissipation space and achieves efficient heat exchange in conjunction with the ventilation channels. Multiple sets of fixing slots 8 support parallel or layered installation of cables of different specifications.
