[0033] The locking mechanism includes a mounting shaft A410 and a locking gear 420. A ratchet 430 is fixed to the inner wall of the locking gear 420. A mounting slide cover 440 is fixed to one end of the mounting shaft A410. A pair of support columns 450 are slidably connected to the inner wall of the mounting slide cover 440. Pads 460 are rotatably connected to the outer sides of each pair of support columns 450. An unlocking mechanism is provided on one side of the mounting slide cover 440. By providing a positioning mechanism and a docking mechanism, when installing the cable tray, the toothed insert 230 is inserted into the slot 330, and the locking mechanism secures the toothed insert 230. The automated locking and positioning system enables quick installation of the cable tray. The locking mechanism releases the pawl 460 from the locking gear 420, allowing the toothed insert 230 to be pulled out of the slot 330 for quick disassembly of the cable tray. Installation and disassembly can be completed without tools, reducing the difficulty of installation and disassembly and improving laying efficiency. The fire-resistant ceramic fiber layer 120 provides fire protection to the inner wall of the cable tray body 100, preventing fire spread and improving safety during use.

[0034] Specifically, the outer side of the mounting side plate A210 is provided with multiple fastening bolts A211; the mounting side plate A210 is installed on the side wall of the cable tray body 100 by means of the fastening bolts A211. The positioning mechanism adopts a modular structure, which makes it convenient to install the positioning mechanism on any cable tray.

[0035] Specifically, a pair of positioning blocks 220 are fixed to the side wall of the mounting side plate A210, and a pair of slots 320 are fixed to the side wall of the mounting side plate B310. By providing positioning blocks 220 and slots 320, when installing the cable tray, the positioning blocks 220 are aligned with the slots 320 and inserted, which can perform positioning operations for the installation of the cable tray and ensure the accuracy of the installation operation.

[0036] Specifically, the mounting side plate B310 is provided with multiple fastening bolts B311 on its outer side; the mounting side plate B310 is installed on the side wall of the cable tray body 100 by means of the fastening bolts B311. The docking mechanism adopts a modular structure, which makes it convenient to install the docking mechanism on any cable tray.

[0037] Specifically, an installation shaft B470 is fixed to the inner wall of the installation side plate B310, and a support gear 480 is rotatably connected to the outer side of the installation shaft B470; by setting the support gear 480 to limit and support the insertion of the toothed plug 230, the stability of the cable tray installation operation is ensured.

[0038] Specifically, the unlocking mechanism includes a mounting block 510, which is fixed to one side of the mounting slide cover 440. A mounting slide rod 520 is fixed to one side of the mounting block 510. A spring 521 is provided on the outer side of the mounting slide rod 520. A sliding seat 530 is slidably connected to the outer side of the mounting slide rod 520 near the spring 521. A driving block 540 is fixed to the end of the support column 450. The driving block 540 is fixedly connected to the sliding seat 530. By setting the unlocking mechanism, the pawl 460 is driven to disengage from the ratchet 430. At this time, the pawl 460 releases the one-way locking state of the locking gear 420. The locking gear 420 can rotate freely on the mounting shaft A410, and the toothed insert 230 can be pulled out from the slot 330, thereby realizing the convenient disassembly of the cable tray.

[0039] Working principle: During use, the top of the cable tray body 100 is sealed and covered by the cover plate 110, and the inner wall of the cable tray body 100 is fireproofed by the fireproof ceramic fiber layer 120, which can prevent the spread of fire. When installing the cable tray, the positioning block 220 is aligned with the slot 320 and inserted to position the cable tray. The toothed block 230 is inserted into the slot 330. The movement of the toothed block 230 drives the locking gear 420 to rotate in the forward direction. The ratchet 430 and the pawl 460 work together to suppress the reverse rotation of the locking gear 420, so that the locking gear 420 keeps rotating in one direction. One end of the toothed block 230 is pressed against the spring. The support block 340 can automatically lock and position the toothed insert 230, thereby enabling quick installation of the cable tray. When it is necessary to disassemble the installed cable tray, the drive block 540 is turned to move the support column 450 toward the center of the locking gear 420, thereby causing the pawl 460 to disengage from the ratchet 430. At this time, the pawl 460 releases the one-way locking state of the locking gear 420, and the locking gear 420 can rotate freely on the mounting shaft A410, so that the toothed insert 230 can be pulled out from the slot 330, thereby realizing convenient disassembly of the cable tray. The installation and disassembly of the cable tray can be completed without contact with tools, reducing the difficulty of installing and disassembling the cable tray.
