DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] See also Figures 1 to 6 As shown, an advertising light box structure in a subway tunnel includes a positioning frame 1 and a light box frame 2. The positioning frame 1 is installed on the tunnel wall, and the light box frame 2 is connected to the positioning frame 1. The connection between the two is detachable. A side panel is also connected between the positioning frame 1 and the light box frame 2. After assembly, the side panel is in an inclined state, and its far end is against the wall inside the tunnel.

[0026] When the light box frame 2 is connected to the positioning frame 1, the light box frame 2 is located at the center of the positioning frame 1. After the position of the light box frame 2 is locked, the side panels and the light box frame 2 cooperate to clamp the advertising light box 3 located in the light box frame 2.

[0027] Specifically, the light box frame 2 is connected to the back plate 4, the light box frame 2 is fixed on the back plate 4, and the back plate 4 and the light box frame 2 are surrounded by the positioning frame 1 at the same time, wherein the back plate 4 and the positioning frame 1 are connected by bolts, and after the back plate 4 and the positioning frame 1 are connected, the light box frame 2 is located at the center of the positioning frame 1;

[0028] It should be noted that there are four side panels, and the four side panels are arranged to form a square frame. Each side panel is composed of an outer panel 5 and an inner panel 6. The outer panel 5 is hinged to the positioning frame 1, and the outer panel 5 is connected to the light box frame 2. When the side of the outer panel 5 close to the light box frame 2 flips upward, the outer panel 5 applies a supporting force to the inner panel 6, so that the part of the inner panel 6 located above the light box flips downward, and the inner panel 6 applies a pressing force to the advertising light box 3, so that the back panel 4 and the inner panel 6 cooperate to form a clamping position for the advertising light box 3;

[0029] When controlling the outer panel 5 to flip, the inner support structure 7 is used to apply a supporting force to the outer panel. The inner support structure 7 includes an inner partition 8 and an outer partition 9 arranged around the light box frame 2. The inner partition 8 and the outer partition 9 are both fixed on the back plate 4. The inner partition 8 and the outer partition 9 are both U-shaped frames. An intermediate area is formed between the inner partition 8 and the outer partition 9. At this time, the intermediate area is also U-shaped, and a movable U-shaped support frame 10 is provided in the intermediate area. The U-shaped support frame 10 can be moved out of the intermediate area. During the moving out process, the U-shaped support frame 10 contacts the outer panel 5 and applies a supporting force to the outer panel 5.

[0030] When the return-shaped support frame 10 is controlled to move out of the middle area, a bottom airbag 11 is arranged in the middle area. The bottom airbag 11 is also return-shaped. After the bottom airbag 11 is inflated, the bottom airbag 11 will expand. However, since the bottom airbag 11 is located in the middle area at this time, the return-shaped support frame 10 will be supported to move toward the outer plate 5 after the bottom airbag 11 expands. When the return-shaped support frame 10 contacts the outer plate 5, as the bottom airbag 11 continues to expand, an upward supporting force will be applied to the outer plate 5 through the movement of the return-shaped support frame 10.

[0031] A sealing gasket 12 is arranged on the above-mentioned U-shaped support frame 10, and the sealing gasket 12 is also in the shape of a U.S. character. When the U-shaped support frame 10 contacts the outer plate 5, the sealing gasket 12 rests on the lower surface of the outer plate 5. At this time, a sealing strip is also arranged on the lower surface of the inner panel 6, that is, after the advertising light box 3 is clamped, a sealing separation zone is formed around the light box frame 2, so that the environment outside the inner support structure 7 is separated from the environment inside thereof, and at this time, the environment inside the inner support structure 7 has better sealing performance.

[0032] In addition, the inner panel 6 includes a flip support plate 13 and a flip clamp plate 14. The bottom long side of the flip support plate 13 is hinged to the light box frame 2, and the flip clamp plate 14 is hinged to the top long side of the flip support plate 13. When the flip support plate 13 is flipped to form contact with the light box frame 2, the flip clamp plate 14 is located above the light box frame 2. If the flip clamp plate 14 is in a horizontal state at this time, there will be a certain distance between the flip clamp plate 14 and the light box frame 2. Such a setting can have a certain adaptability and can clamp advertising light boxes of different thicknesses.

[0033] A locking card 15 is hinged on the flip support plate 13, and the locking card is a crescent-shaped plate body. An elastic component 16 is connected between the locking card 15 and the flip support plate 13. The elastic component 16 can be a compression return spring or an arched spring sheet with elasticity. At the same time, a long through-hole is provided on the light box frame 2. When the flip support plate 13 is flipped toward the vertical state, the locking card 15 will enter through the through-hole, and then as the flip support plate 13 is flipped, the locking card 15 applies a pushing force to the advertising light box 3, thereby forming a lateral clamping of the advertising light box 3;

[0034] The flipping of the flipping plate 13 is affected by the return-shaped support frame 10. When the return-shaped support frame 10 moves outward from the middle area, the flipping plate 13 is supported to flip the flipping plate 13 toward the vertical state. Specifically, a vertical notch is provided on the inner partition 8, and a flat support rod 17 is provided on the return-shaped support frame 10. The flat support rod 17 passes through the vertical notch and is horizontally arranged. When the bottom airbag 11 is not inflated, the flipping plate 13 is in a horizontal state. At this time, the flipping plate 13 is placed on the flat support rod 17. Then, when the bottom airbag 11 is inflated, the flat support rod 17 moves upward with the return-shaped support frame 10. At this time, the flat support rod 17 moves in the vertical notch, so that the flipping plate 13 is controlled to flip toward the vertical state through the flat support rod 17. At this time, the flat support rod 17 applies a supporting force to the outer plate 5.

[0035] During the implementation of the utility model, it is necessary to first connect the back plate 4 with the positioning frame 1 by bolts, and then install the positioning frame 1 on the wall inside the tunnel. After that, the advertising light box 3 is assembled in the light box frame 2, and by inflating the bottom airbag 11, the advertising light box 3 can be quickly clamped and positioned through the cooperation of the outer panel 5 and the inner panel 6, which is convenient for installation and disassembly, can improve construction efficiency, and at the same time, the stability of the advertising light box is better.
