All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Example 1, by Figure 1 The present invention relates to a lightweight splicing cable tray, comprising a main cable tray 1 and a secondary cable tray 3, wherein a splicing mechanism 2 is provided between the main cable tray 1 and the secondary cable tray 3, and multiple through grooves 4 are provided at equal intervals at the bottom of the main cable tray 1 and the secondary cable tray 3. Both the main cable tray 1 and the secondary cable tray 3 are made of aluminum alloy, and the through grooves 4 are provided at the bottom of both the main cable tray 1 and the secondary cable tray 3, thereby achieving the lightweighting of the entire cable tray.

[0025] Specifically, by Figure 2-4The splicing mechanism 2 includes an outer frame 201 fixed to the outside of the sub-cable tray 3. Two side plates 202 are symmetrically fixed to the outside of the outer frame 201. The main cable tray 1 is located between the two side plates 202. L-shaped plates 203 are rotatably connected to the side of each side plate 202 away from the outer frame 201. Limiting grooves 2014 are provided on the side of each L-shaped plate 203 near the outer frame 201. A top block 207 is fixedly connected to the top of the main cable tray 1. A guide rod 2013 is fixedly connected to the outside of the top block 207. Two guide rods 2013 abut against each other. A guide plate 209 is movably sleeved on the outside of the guide rod 2013. Two guide plates 209 are symmetrically fixed to the top of the guide plate 209. Two limiting plates 2010 are inserted into two limiting slots 2014 respectively. Two side frames 206 are symmetrically fixedly connected to the outside of the main cable frame 1. The two side frames 206 are respectively sleeved on the outside of the two side plates 202. A screw 204 is rotatably connected to the outside of the top block 207. A turntable 2012 is fixedly connected to the end of the screw 204 away from the top block 207. A screw sleeve 208 is threaded on the outside of the screw 204. A guide plate 209 is fixed to the bottom of the screw sleeve 208. A sleeve block 2011 is fixedly sleeved on the middle of the outside of the guide round rod 2013. The sleeve block 2011 is fixed to the top of the main cable frame 1. The screw 204 passes through the sleeve block 2011 and is rotatably connected to the sleeve block 2011.

[0026] In use, first, pass the two side plates 202 through the side frame 206 until the sub-cable tray 3 is in contact with the main cable tray 1. Then, rotate the two L-shaped plates 203 until they both abut against the guide rod 2013. Then, rotate the turntable 2012 to drive the screw 204 to rotate. Through the screw sleeve 208, drive the guide plate 209 to slide along the guide rod 2013. At the same time, the two limiting plates 2010 move horizontally until the two limiting plates 2010 are inserted into the two limiting grooves 2014 respectively. Fix the two L-shaped plates 203 to the top block 207 and fix the main cable tray 1 and the sub-cable tray 3. Finally, the main cable tray 1 and the sub-cable tray 3 can be quickly spliced.

[0027] Specifically, by Figure 5 As shown, the top block 207 has a positioning groove 2019 on the side near the outer frame 201, and a positioning plate 205 is fixedly connected to the side of the outer frame 201 near the top block 207.

A movable rod 2015 is rotatably connected to the outside of the lifting plate 2016. The end of the movable rod 2015 away from the lifting plate 2016 is rotatably connected to the top of the screw sleeve 208.

[0028] In use, when the main cable tray 1 and the auxiliary cable tray 3 are in contact, the positioning plate 205 is inserted into the positioning groove 2019. When the rotating turntable 2012 is rotated, the screw 204 is driven to rotate. Since the guide plate 209 fixed at the bottom of the screw sleeve 208 is movably sleeved on the outside of the guide rod 2013, it guides the screw sleeve 208. When the screw 204 rotates, it drives the screw sleeve 208 to move horizontally. Then, the movable rod 2015 drives the lifting plate 2016 to slide down along the U-shaped rod 2020. At the same time, the insertion rod 2017 descends until it is inserted into the insertion hole 2018, fixing the top block 207 to the positioning plate 205. Finally, the main cable tray 1 and the auxiliary cable tray 3 are firmly connected.
