As shown in Figure 1-4, a gantry light box with a lifting function includes a light box body 1. Two sets of fixed cylinders 2 are provided on the upper side of the light box body 1. The inner sides of the two sets of fixed cylinders 2 are movably connected with movable rods 3. The movable rods 3 moves through the fixed cylinder 2 and extends to the outside, and the outer end of the movable rod 3 is located on the outer part of the fixed cylinder 2 and is fixedly connected to the light box body 1. A return spring 4 is provided inside the fixed cylinder 2, and one end of the return spring 4 is connected to the fixed cylinder 2. And the other end of the return spring 4 is connected to the movable rod 3. The upper end of the movable rod 3 is located on the inner part of the return spring 4 and is fixedly provided with a second magnet 6. The inner side of the fixed cylinder 2 is fixedly provided with a first magnet 5 that docks with the second magnet 6 and is movable. A mounting groove 7 is provided on the inside of the rod 3, and a positioning mechanism 8 is provided on the inside of the installation groove 7. A plurality of sets of positioning holes 9 for docking positioning mechanisms 8 are provided on the outside of the fixed cylinder 2. When repairing the light box body 1, the staff only need to You only need to bring the corresponding tools and an L-shaped rod. Pull the light box body 1 downward through the L-shaped rod, and you can quickly repair the light box body 1. There is no need to use climbing tools for climbing operations, thus greatly reducing the work intensity. Improve work efficiency.

Among them, the upper end of the fixing cylinder 2 is fixed with a mounting plate 10. The mounting plate 10 has multiple sets of mounting holes 11 running through it up and down. By inserting bolts into the mounting holes 11, the fixing cylinder 2 can be firmly fixed on the suspended ceiling, improving the fixation. The installation stability of barrel 2 is thereby effectively improved the overall stability of the device.

Among them, a rotating rod 12 is rotated on the inside of the light box body 1, and a power cord 13 is rolled up on the outside of the rotating rod 12. One end of the power cord 13 movablely penetrates the light box body 1 and extends to the outside. The rotating rod 12 can rewind the power cord 13. This prevents the power cord 13 from being messy inside the light box body 1 and facilitates later maintenance by the staff.

Among them, two sets of limiting disks 14 are fixedly provided on the outer part of the rotating rod 12 and outside the power cord 13. The two sets of limiting disks 14 can limit the position of the power cord 13 rolled up by the rotating rod 12, and improve the power cord 13 of the rotating rod 12. The rolling effect.

Among them, a coil spring 15 is set on the outside of the rotating rod 12. One end of the coil spring 15 is connected to the limit plate 14, and the other end of the coil spring 15 is connected to the inside of the light box body 1. When the light box body 1 is pulled down, it can drive the rotation. The rod 12 rotates and unwinds both ends of the power cord 13 to facilitate the movement of the light box body 1. At this time, the rotating rod 12 will also stretch the coil spring 15. When the light box body 1 moves upward to reset, the coil spring 15 will automatically shrink. And drives the rotating rod 12 to rotate and reset. At this time, the rotating rod 12 automatically winds up the power cord 13 just released, which is very flexible and convenient to use.

Among them, the positioning mechanism 8 includes a limit spring 16 arranged inside the installation groove 7. One end of the limit spring 16 is connected to the inner wall of the installation groove 7, and the other end of the limit spring 16 is provided with a movable disk 17. The outside of the movable disk 17 is fixedly provided with The positioning post 18 and the limit spring 16 are initially elastic, and when the positioning post 18 is staggered from the positioning hole 9, the positioning post 18 presses against the inner wall of the fixed cylinder 2, which facilitates the movement of the movable rod 3 inside the fixed cylinder 2. When the positioning post 18 is docked with the positioning hole 9, the limit spring 16 stretches and drives the positioning post 18 to be inserted into the positioning hole 9, thereby facilitating the fixation of the movable rod 3 and the light box body 1. Since the positioning hole 9 is provided with multiple , the staff can adjust the height of the light box body 1 according to actual needs.

Among them, an anti-slip surface 19 is fixedly provided on the upper side of the light box body 1. When the L-shaped rod is used to hook the light box body 1, the anti-slip surface 19 can increase the friction and prevent the L-shaped rod from slipping on the upper side of the light box body 1, so that It is easier to pull the light box body 1 downward.

Embodiment: During use of the utility model, bolts are first inserted into the mounting holes 11 to install the light box body 1 on the suspended ceiling. At this time, the return spring 4 contracts to drive the first magnet 5 and the second magnet 6 to attract each other. , can fix the movable rod 3 to ensure the installation stability of the light box body 1. When the light box body 1 fails and needs to be repaired, an L-shaped pole can be used to hang the L-shaped pole on the upper side of the light box body 1. on the anti-slip surface 19, and then pull the L-shaped rod downward with force. The L-shaped rod moves downward and exerts a downward pulling force on the light box body 1. At this time, the movable rod 3 stretches the return spring 4 and forces the first magnet 5 is separated from the second magnet 6, causing the movable rod 3 to move downward in the fixed cylinder 2. When the movable rod 3 moves downward, it drives the light box body 1 to move downward until the installation groove 7 is docked with a set of positioning holes on the outside of the fixed cylinder 2. At 9 o'clock, the limit spring 16 stretches and drives the movable plate 17 and the positioning column 18 to move outward. When the positioning column 18 moves outward, it is inserted into a set of positioning holes 9, thereby fixing the movable rod 3. At this time, the light box The body 1 is also fixed to facilitate the maintenance of the light box body 1. After the maintenance is completed, the positioning post 18 is pressed into the installation groove 7, so that the positioning post 18 is detached from the positioning hole 9, and then the return spring 4 Under the action of elasticity, the movable rod 3 is driven to move upward in the fixed tube 2. When the movable rod 3 moves upward, it drives the light box body 1 to move upward until the first magnet 5 and the second magnet 6 contact and attract each other, so that the light box body 1 can be fixed. .
