A storage battery 8 is installed on the bottom outer wall of the cable tray body 1, and the electrical output terminal of the storage battery 8 is electrically connected to the electrical input terminal of a motor 2011, providing power to the motor 2011 for operation.

[0023] The modular splicing assembly 2 includes a guide hole 201, a first adjusting plate 202, a locking rod 203, a first spring 204, a support plate 205, a guide opening 206, a moving frame 207, a connecting plate 208, a second spring 209, a first arc-shaped protrusion 2010, a motor 2011, an elliptical wheel 2012, a splicing frame 2013, and a locking hole 2014. The cable tray body 1 has a first adjusting plate 202 installed on both sides of its exterior. A locking rod 203 is symmetrically fixed to one side of the outer wall of the first adjusting plate 202. Guide holes 201 are distributed on both sides of the cable tray body 1 corresponding to the positions of the locking rods 203. A locking rod 203 is symmetrically fixed to one side of the outer wall of the first adjusting plate 202. A first spring 204 is fixedly connected, and the other end of the first spring 204 is fixedly connected to the outer walls of both sides of the cable tray body 1. A splicing frame 2013 is fixedly connected to one outer wall of the cable tray body 1. The splicing frame 2013 has locking holes 2014 distributed on both sides corresponding to the locking rod 203. A support plate 205 is fixedly connected to both outer walls of the cable tray body 1. A guide opening 206 is opened on the support plate 205. A movable frame 207 is slidably installed in the guide opening 206. A first arc-shaped protrusion 2010 is symmetrically fixed to one side of the movable frame 207 corresponding to the position of the first adjusting plate 202. A connecting plate 208 is fixedly connected to both outer walls of the movable frame 207. A second spring 209 is fixedly connected to one side of the outer wall of the connecting plate 208, and the other end of the second spring 209 is fixedly connected to the outer wall of the support plate 205. An elliptical wheel 2012 is fitted onto one side of the outer wall of the moving frame 207. A motor 2011 is embedded in the bottom end of the cable tray body 1, and the bottom end of the output shaft of the motor 2011 is fixedly connected to the outer wall of the elliptical wheel 2012. When the motor 2011 is started, the elliptical wheel 2012 continues to rotate 90 degrees, causing the elliptical wheel 2012 to separate from the moving frame 207. Then, under the action of the second spring 209 on the connecting plate 208, the moving frame 207 is reset along the guide opening 206 on the support plate 205. Then, the first arc-shaped protrusion 2010 on the support plate 205 is separated from the first adjusting plate 202. Then, under the action of the first spring 204, the locking rod 203 on the first adjusting plate 202 is reset along the guide hole 201, so that the locking rod 203 is inserted into the locking hole 2014 on the splicing frame 2013. The first spring 204 is sleeved on the outer wall of the locking rod 203, and there are four first springs 204. When the elliptical wheel 2012 is separated from the moving frame 207, the moving frame 207 is reset along the guide opening 206 on the support plate 205 under the action of the second spring 209 on the connecting plate 208.

[0024] Working principle: First, the motor 2011 is started, causing the elliptical wheel 2012 to rotate 90 degrees. The protrusion of the elliptical wheel 2012 presses against the moving frame 207, causing the moving frame 207 to move along the guide opening 206 on the support plate 205. This causes the first arc-shaped protrusion 2010 on the support plate 205 to press against the first adjusting plate 202, causing the locking rod 203 on the first adjusting plate 202 to move along the guide hole 201. Then, the splicing frame 2013 on the cable tray body 1 is inserted into the interior of another cable tray body 1. Then, the motor 2011 is started again, causing the elliptical wheel 2012 to continue rotating 90 degrees, causing the elliptical wheel 2012 to separate from the moving frame 207. Then, under the action of the second spring 209 on the connecting plate 208, the moving frame 207 is reset along the guide hole 206 on the support plate 205. Then, the first arc-shaped protrusion 2010 on the support plate 205 is separated from the first adjusting plate 202. Then, under the action of the first spring 204, the locking rod 203 on the first adjusting plate 202 is reset along the guide hole 201. The locking rod 203 is inserted into the locking hole 2014 on the splicing frame 2013, thereby splicing the cable tray body 1. The cable tray can be spliced ​​through the locking structure, which simplifies the installation process, reduces the installation burden, and improves the installation effect of the equipment.

Cable clamping seats 307 are symmetrically fixed to the inner wall of the bottom end of the cable tray body 1. A cable clamping frame 308 is installed above the cable clamping seat 307. A lifting rod 3010 is symmetrically fixed to the outer wall of the bottom end of the cable clamping frame 308. Lifting holes 306 are symmetrically opened at the bottom end of the cable tray body 1 corresponding to the positions of the lifting rod 3010. A third spring 302, a guide plate 303, a vertical plate 304, a second arc-shaped protrusion 305, a lifting hole 306, and a fourth spring 309 are fixed to the outer wall of the bottom end of the lifting rod 3010. The second adjusting plate 3011 and the bottom of the cable clamping frame 308 are symmetrically fixed with a fourth spring 309, and the bottom of the fourth spring 309 is fixed to the inner wall of the cable tray body 1. A guide frame 301 is fixed to the bottom outer wall of the cable tray body 1. A guide plate 303 is installed inside the guide frame 301.

A third spring 302 is fixed to the outer wall of one side of the vertical plate 304. The other end of the third spring 302 is fixed to the outer wall of the guide frame 301.

[0027] When the cable needs to be installed, the cable is placed inside the cable clamp seat 307. At this time, the motor 2011 is started to rotate the elliptical wheel 2012 90 degrees. The protrusion of the elliptical wheel 2012 presses against the vertical plate 304, causing the guide plate 303 on the second arc-shaped protrusion 305 to move along the guide frame 301. Then, the second arc-shaped protrusion 305 presses against the second adjusting plate 3011, causing the lifting rod 3010 on the cable clamp frame 308 to descend along the lifting hole 306, so that the cable clamp frame 308 engages with the cable clamp seat 307. Then, the cover plate 5 is inserted into the guide rail 4 to protect the cable. Then, the cable tray body 1 is lifted, and then the connecting nut 7 on the connecting rod 6 is rotated to connect with the basement screw. The cable tray body 1 is fixed to the basement ceiling by threaded connection. When cable maintenance is required, the starter motor 2011 is activated to reset the elliptical wheel 2012, separating it from the vertical plate 304. Then, under the action of the third spring 302, the guide plate 303 on the second arc-shaped protrusion 305 is reset along the guide frame 301. At this time, under the action of the fourth spring 309, the lifting rod 3010 on the cable clamping frame 308 rises along the lifting hole 306, separating the cable clamping frame 308 from the cable clamping seat 307. Then, the cable can be maintained. The clamping structure can fix the position of the cable, which simplifies the installation process, reduces the cable fixing effect, and improves the cable fixing effect.
