[0027] Combined with appendix Figure 1-3This embodiment of a hanging light box includes a light box 1, a hanging rod 2, a clamp 3, a telescopic adjusting rod 4, a first fixed seat 5, and a second fixed seat 6. Both the first fixed seat 5 and the second fixed seat 6 are fixed to the ceiling with expansion screws. Two second fixed seats 6 are equidistantly arranged on both sides of the first fixed seat 5. The upper end of the hanging rod 2 is rotatably connected to the first fixed seat 5 via a first pin 7, allowing the hanging rod 2 to swing relative to the first fixed seat 5 around the first pin 7. The lower end of the hanging rod 2 is connected to the top of the light box 1. The clamp 3 is fitted onto the hanging rod 2, and the inner diameter of the clamp 3 matches the outer diameter of the hanging rod 2. The telescopic adjusting rod 4 is symmetrically arranged at both ends of the first pin 7. The upper end of the telescopic adjusting rod 4 is rotatably connected to the second fixed seat 6 via a hook 8. The second fixed seat 6 has a hanging ring that cooperates with the hook 8. The lower end of the telescopic adjusting rod 4 is rotatably connected to the clamp 3 via a second pin 9. Both the first pin 7 and the second pin 9 are horizontally arranged and their axes are perpendicular. Figure 2 As shown, the first pin 7 is set in the left-right horizontal direction, and the second pin 9 is set in the front-back horizontal direction.

[0028] After the hanging rod 2 is straightened by gravity, the telescopic adjustment rods 4 on both sides can easily adjust the verticality of the hanging rod 2 by adjusting their own length, making the light box 1 more stable after installation and less prone to shaking.

[0029] As a preferred embodiment of this utility model, the telescopic adjusting rod 4 is a turnbuckle. The turnbuckle includes an adjusting rod 41, with a first screw 42 and a second screw 43 threadedly connected to both ends of the adjusting rod 41. The first screw 42 and the second screw 43 are coaxially arranged. The first screw 42 is connected to the second fixing seat 6 through the second pin 9, and the second screw 43 is connected to the hook 8. When the adjusting rod 41 rotates, the axial distance between the first screw 42 and the second screw 43 can be adjusted, thereby adjusting the overall length of the turnbuckle.

[0030] As a preferred embodiment of this utility model, a straight rod 44 is provided between the first screw 42 and the second screw 43. The straight rod 44 is coaxially arranged with the first screw 42 and the second screw 43. One end of the straight rod 44 is fixedly connected to the first screw 42, and the other end of the straight rod 44 is inserted into the second screw 43. The second screw 43 has a slot that mates with the straight rod 44 at one end near the first screw 42. The outer surface of the straight rod 44 is marked with a scale along its length. The operator can observe the distance between the first screw 42 and the second screw 43 through the scale exposed on the straight rod 44, so that the turnbuckles on both sides can be pre-adjusted to the same scale in the initial adjustment and then fine-tuned.

[0031] As a preferred embodiment of this utility model, the bottom of the light box 1 is provided with an airbag protective device 10. The airbag protective device 10 forms a flexible buffer structure at the bottom of the light box 1, which is mainly opened during the maintenance of the light box to reduce the impact caused by the accidental fall of the light box.

[0032] As a preferred embodiment of this utility model, the airbag protection device 10 includes a base plate 101, fixedly connected to the bottom of the light box 1; an airbag 102, disposed below the base plate 101, which extends to the outer side of the bottom of the light box 1 after inflation; and an air pump 103 connected to the airbag 102, the pump 103 being connected to the airbag 102 via an air pipe 104, on which a solenoid valve 105 is provided. The working principle of this airbag protection device 10 is as follows: during maintenance, the air pump 103 is turned on to inflate the airbag 102. After maintenance, the air pump 103 reverses the flow to extract air until the airbag 102 is in a vacuum state.

[0033] As a preferred embodiment of this utility model, the base plate 101 is disposed inside the light box 1, and the space formed between the base plate 101 and the bottom of the light box 1 is used to accommodate the airbag 102 in a vacuum state, so that the airbag 102 is hidden inside the light box 1 when not in use, and does not affect the aesthetics of the light box.

[0034] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
