[0023] Example

[0024] refer to Figures 1-6 A cable tray with a retractable function includes a cable tray body 1 and extension components 2 disposed at both ends of the cable tray body 1. The cable tray body 1 includes a cable tray base plate 11. Cable tray side plates 12 are symmetrically arranged on both sides of the cable tray base plate 11. A first mounting plate 121 is fixedly connected to the inner side wall of the cable tray side plate 12. A first connecting groove 122 is opened at one end of the first mounting plate 121 near the cable tray body 1. A connecting plate 123 is slidably disposed in the first connecting groove 122. A first fixing hole 125 is opened through the connecting plate 123 for inserting a fixing bolt 124.

[0025] The extension assembly 2 includes two rotatably mounted extension base plates 21 at the bottom of the cable tray body 1. Extension side plates 22 are slidably connected to the extension base plates 21. A second assembly plate 221 extending along the length of the extension side plate 22 is fixedly connected to the outer wall of the extension side plate 22. A second connecting groove 222 is provided on one side of the second assembly plate 221, which communicates with the first connecting groove 122 after the extension base plates 21 are rotated.

[0026] Furthermore, both the upper and lower ends of the connecting plate 123 are provided with insert plates 126 extending along the length of the connecting plate 123. The first assembly plate 121 and the second assembly plate 221 are both provided with insert grooves 127 for insert plates 126 to be inserted into. Through the setting of insert grooves 127 and insert plates 126, the connection between the connecting plate 123 and the extension side plate 22 and the cable tray side plate 12 is more stable, thereby making the connection between the extension component 2 and the cable tray body 1 more stable.

[0027] Furthermore, the bottom end face of the extended side plate 22 is provided with a limiting block 223, and the top end face of the extended base plate 21 is provided with a limiting groove 211 that allows the limiting block 223 to move. Through the setting of the limiting groove 211 and the limiting block 223, the extended side plate 22 can slide on the extended base plate 21 according to the usage requirements and the displacement of the extended side plate 22 can be limited.

[0028] Furthermore, the extended side plate 22 has a through-hole 224 for completely housing the connecting plate 123 into the second connecting groove 222 and communicating with the first fixing hole 125. By sequentially inserting the fixing bolts 124 into the first fixing hole 125 and the second fixing hole 224, the connecting plate 123 is housed and fixed in the second connecting groove 222, thereby preventing the connecting plate 123 from slipping out. The cable tray side plate 12 has a through-hole 128 for the front part of the connecting plate 123 to be inserted into the first connecting groove 122 and communicating with the first fixing hole 125. By sequentially inserting the fixing bolts 124 into the third fixing hole 128 and the first fixing hole 125, the connecting plate 123 is fixedly connected to the cable tray side plate 12. The rear part of the connecting plate 123 is inserted into the second connecting groove 222, thereby restricting the movement of the extended side plate 22 and the rotation of the extended base plate 21, thus ensuring the stability of the connection between the extended assembly 2 and the cable tray body 1.

[0029] Furthermore, the end of the extended base plate 21 away from the port of the cable tray body 1 is provided with a first fastening hole 213 for inserting fastening bolts 212. The cable tray base plate 11 is provided with a second fastening hole 111 for storing the extended base plate 21 at the bottom of the cable tray body 1 and communicating with the first fastening hole 213. By sequentially inserting the fastening bolts 212 into the first fastening hole 213 and the second fastening hole 111, the extended component 2 is stored and fixed at the end of the cable tray body 1.

[0030] Preferably, the first fixing hole 125, the second fixing hole 224, the third fixing hole 128, the first fastening hole 213, and the second fastening hole 111 are all internal threaded holes with the same structural dimensions, and the fixing bolt 124 and the fastening bolt 212 have the same structural dimensions, thereby improving the convenience of installation for workers.

[0031] The working principle of this utility model:

[0032] During installation, when the length of the cable tray needs to be adjusted, the worker loosens and removes the fixing bolts 124, releasing the connecting plate 123 from the cable tray side plate 12. The connecting plate 123 is then pushed to retract completely into the second connecting groove 222 on the extended side plate 22. At this point, the first fixing hole 125 on the connecting plate 123 connects with the second fixing hole 224 on the extended side plate 22. The fixing bolts 124 are then inserted sequentially into the first fixing hole 125 and the second fixing hole 224, fixing the connecting plate 123 into the second connecting groove 222. Finally, the extended side plate 22 is pushed to retract... 2. Move to the other end of the limiting groove 211, and then rotate the extension base plate 21 180 degrees so that the side of the extension side plate 22 away from the second assembly plate 221 is in contact with the outer wall of the cable tray side plate 12. At this time, the first fastening hole 213 on the extension base plate 21 is connected to the second fastening hole 111 on the cable tray base plate 11. Insert the fastening bolts 212 into the first fastening hole 213 and the second fastening hole 111 in sequence so that the extension component 2 is stored and fixed at the end of the cable tray body 1. The staff can rotate and store the extension component 2 at one end or both ends of the cable tray body 1 according to the needs of the site, so as to meet the usage requirements.
