[0018] Please see Figures 1 to 10 The present invention provides a technical solution: a low-voltage cable tray connector, comprising... The first cable tray 1 has a sliding groove 2 on its end side, and a first movable plate 3 is slidably disposed in the sliding groove 2. A plug-in assembly 5 is fixedly installed on the side of the first cable tray 1, and the first cable tray 1 is plugged into and cooperates with the second cable tray 4 through the plug-in assembly 5. An adjustment groove 6 is provided on the inner side of the second cable tray 4, and a second movable plate 7 is slidably disposed on the side of the adjustment groove 6. A fixing horizontal hole 8 is provided on the side of the first cable tray 1, and a fixing square piece 9 is disposed on the side of the fixing horizontal hole 8. A fixing vertical hole 10 is provided on the side of the second cable tray 4, and a fixing square piece 9 is also disposed on the side of the fixing vertical hole 10. Fastening bolts are disposed on the inner sides of the fixing vertical hole 10 and the fixing horizontal hole 8.

[0019] A limiting block 11 is fixedly installed on the side of the first cable tray 1 near the end of the second cable tray 4. A through hole 12 is opened on the side of the limiting block 11, and the first moving plate 3 is slidably disposed in the through hole 12. A limiting block 11 is also provided on the side of the second cable tray 4 near the first cable tray 1. The second moving plate 7 is slidably disposed in the through hole 12, and the second moving plate 7 is slidably engaged with the first moving plate 3. A guide block 13 is fixedly installed on the side of the adjusting groove 6, and a guide groove 14 is opened on the side of the second moving plate 7. The guide block 13 and the guide groove 14 are slidably engaged, which limits the second moving plate 7 and guides the second moving plate 7, thereby improving the connection stability between the second moving plate 7 and the second cable tray 4.

[0020] The side of the first movable plate 3 has the same horizontal hole 8 as the first cable tray 1, and a set of fixed vertical holes 10 are fixedly provided near the fixed horizontal hole 8. The fixed vertical holes 10 and the fixed horizontal hole 8 form a cross shape. The ends of the first movable plate 3 and the second movable plate 7 away from the limiting block 11 are both fixedly installed with a locking block 15. The locking block 15 is engaged with the limiting block 11. The structure of the locking block 15 can ensure the connection between the first movable plate 3 and the second movable plate 7 and the first cable tray 1 and the second cable tray 4, and prevent the first movable plate 3 and the second movable plate 7 from coming off, thus providing a stable foundation for the subsequent connection of the first movable plate 3 and the second movable plate 7.

[0021] The plug-in assembly 5 includes an extension plate 16, which is fixedly connected to the first cable tray 1. Two sets of auxiliary rods 17 are fixedly installed on the top of the extension plate 16. A plug-in plate 18 is slidably fitted on the top of the extension plate 16 and is fixedly connected to the side of the second cable tray 4. A connecting rod 19 is fixedly installed on the top of the extension plate 16, and a connecting plate 20 is fixedly installed on the top of the connecting rod 19. The connecting rod 19 and the connecting plate 20 are designed such that the slot 21 at the bottom of the plug-in plate 18 engages with the connecting rod 19 and slides with the bottom of the connecting plate 20, thus completing the plug-in engagement between the plug-in plate 18 and the extension plate 16. The structural design is reasonable and can improve the connection strength between the first cable tray 1 and the second cable tray 4, avoid breakage at the connection point, and improve the reliability of the structural connection.

[0022] The plug-in plate 18 is fixedly connected to the second cable tray 4. The top of the plug-in plate 18 has a slot 21, which slides with the connecting rod 19. The end of the plug-in plate 18 near the protruding plate 16 is equipped with a hook 22. The bottom of the plug-in plate 18 has an auxiliary groove 23, which is plugged into the auxiliary rod 17. The hook 22 and the auxiliary rod 17 are structurally matched, which not only assists the first cable tray 1 and the second cable tray 4 in docking, but also, by rotating the hook 22 around the auxiliary rod 17, the side of the second moving plate 7 will be restricted from sliding by the fastening bolt in the fixed vertical hole 10. With the positioning and locking of the hook 22 and the auxiliary rod 17, the second cable tray 4 can be limited and fixed. Finally, the first moving plate 3 and the second moving plate 7 are fixed by the fastening bolt, which can form a right angle shape of the first cable tray 1 and the second cable tray 4 in a vertical plane. The operation is simple and the design is reasonable.

[0023] A connecting bracket 24 is fixedly installed on the first bridge frame 1 near the fixed horizontal hole 8. The connecting bracket 24 has an unlocking groove 25 on its side, and the fixing square plate 9 is built into the unlocking groove 25. The fixing square plate 9 has a threaded groove 26 on its side, and a fixing bolt 27 is inserted into the threaded groove 26. A return spring 28 is fixedly installed on the side of the fixing square plate 9, and the end of the return spring 28 away from the fixing square plate 9 is fixedly connected to the first bridge frame 1. A pin 29 is fixedly installed on the side of the fixing square plate 9 and is inserted into the fixed horizontal hole 8 and the fixed vertical hole 10. By utilizing the structural design of the return spring 28, the fixing square plate 9 and the pin 29 fixedly connected to it can fix the second moving plate 7 and the first moving plate 3 in the adjusting groove 6 and the sliding groove 2. Pulling the fixing square plate 9 can quickly release the first moving plate 3 and the second moving plate 7, allowing them to slide in the sliding groove 2 or the adjusting groove 6. The structure is simple and the operation is convenient.

[0024] In practical use: During the straight-line laying of low-voltage cable trays, by pulling up the fixing plate 9, the fixing plate 9 slides in the unlocking slot 25, and drives the pin 29 on the back away from the fixing horizontal hole 8 and the fixing vertical hole 10. At the same time, the connection between the first moving plate 3 and the second moving plate 7 and the sliding groove 2 and the adjusting groove 6 is released. Then, the first moving plate 3 and the second moving plate 7 are pulled out and connected. During the connection process, the plug-in plate 18 on the side of the second cable tray 4 is connected to the extension plate 16 on the side of the first cable tray 1. The slot 21 will slide into the side of the connecting rod 19 until the hook 22 engages with the auxiliary rod 17, completing the extended connection of the straight-line first cable tray 1 and the second cable tray 4. When it is necessary to lay cable trays at horizontal corners, according to the direction of rotation, unlock a single first moving plate 3 and the second moving plate 7, so that the second cable tray 4 and the first cable tray 1 are in a horizontal and vertical state. Similarly, the slot 21 at the bottom of the plug-in plate 18 is connected to the top of the extension plate 16. The connecting rod 19 of the part is snapped into position, and during the insertion and sliding process, the auxiliary groove 23 at the bottom of the plug plate 18 will assist in positioning with the auxiliary rod 17 to improve installation efficiency. When it is necessary to lay a cable tray with a vertical corner, the first moving plate 3 and the second moving plate 7 need to be locked in contact, and then the hook 22 on the side of the plug plate 18 is snapped into the auxiliary rod 17 at the top of the protruding plate 16. Then, the second cable tray 4 is rotated around the auxiliary rod 17. During the rotation of the second cable tray 4, the second moving plate 7 will slide on the side of the first moving plate 3. When it is rotated to a right angle, the side of the second moving plate 7 will be restricted from sliding by the fastening bolt set in the fixed vertical hole 10. With the positioning and snapping of the hook 22 and the auxiliary rod 17, the second cable tray 4 can be limited and fixed. Finally, the first moving plate 3 and the second moving plate 7 are fixed by the fastening bolt, and the connection effect of the first cable tray 1 and the second cable tray 4 with a vertical corner is completed.
