A smoothing roller 3 is rotatably disposed on one side inside the light frame 1, and a driving rod 4 is rotatably disposed on the other side inside the light frame 1. The driving rod 4 extends to the upper side of the light frame 1. Two winding springs 5 are fixedly installed on the driving rod 4 and are distributed up and down. One end of the winding spring 5 away from the driving rod 4 is fixedly installed inside the light frame 1. Two sliding rods 6 are slidably disposed inside the light frame 1. Two fixing clips 7 are rotatably disposed on the sliding rods 6 and are distributed up and down. The fixing clips 7 correspond to the four corners of the advertising poster 2. A traction block 8 is fixedly installed on one side of the fixing clip 7 corresponding to the driving rod 4. A nylon rope 9 is wound around the driving rod 4. Both ends of the nylon rope 9 bypass the driving rod 4 and are fixedly connected to the traction block 8.

[0029] Among them, the four corners of the advertising poster 2 are clamped by the fixing clips 7, and the driving rod 4 is rotated clockwise to wind up the nylon rope 9. At this time, both ends of the nylon rope 9 drive the two sliding rods 6 to slide in the opposite direction through the traction blocks 8. The advertising poster 2 slides into the inside of the light frame 1 along with the sliding rods 6 through the smoothing roller 3, which can keep the surface of the advertising poster 2 flat. When replacing, release the driving rod 4. The driving rod 4 rotates counterclockwise under the action of the winding spring 5 and pulls the two sliding rods 6 to slide in the reverse direction through the nylon rope 9, and the advertising poster 2 can slide out automatically. It is not only convenient to install, but also faster to disassemble compared with the traditional drawer-type light box.

[0030] Furthermore, as Figures 1 - 5 shown, a fluorescent plate 10 is fixedly installed inside the light frame 1. The smoothing roller 3 and the driving rod 4 are respectively rotatably disposed at both ends of the fluorescent plate 10. The fluorescent plate 10 is used to irradiate the advertising poster 2. The fixing clips 7 are slidably disposed on both sides of the fluorescent plate 10, and the sliding directions of the two fixing clips 7 are opposite, which is convenient for the nylon rope 9 to drive the advertising poster 2 to slide between the glass cover plate 11 and the fluorescent plate 10 through the fixing clips 7, improving the advertising warning effect. A glass cover plate 11 is fixedly installed on the light frame 1. The glass cover plate 11 is disposed outside the advertising poster 2. The glass cover plate 11 can protect the advertising poster 2. The advertising poster 2 bypasses the smoothing roller 3 and extends from one side of the fluorescent plate 10 to the other side of the fluorescent plate 10, and the front side of the advertising poster 2 corresponds to the glass cover plate 11. The reverse side of the advertising poster 2 is in contact with the smoothing roller 3 during the sliding process of the advertising poster 2. A chute 15 is opened at the position of the light frame 1 corresponding to the sliding rod 6, and both ends of the sliding rod 6 are slidably disposed inside the chute 15 to reduce the friction of the sliding rod 6.

[0031] Among them, both ends of the nylon rope 9 drive two sliding rods 6 to slide in opposite directions through the traction blocks 8. One end of the advertising picture 2 slides between the glass cover plate 11 and the fluorescent plate 10 through the sliding rod 6, and its front side corresponds to the glass cover plate 11. The other end of the advertising picture 2 slides in the opposite direction to prevent the advertising picture 2 fixed at the four corners from being torn. The flattening roller 3 is used to flatten the advertising picture 2, and at the same time, it can also make the advertising picture 2 transition smoothly, reduce friction, prevent the advertising picture 2 from generating wrinkles and slip marks, and reduce the probability of damage to the advertising picture 2.

[0032] To solve the problem of fixing the driving rod 4:

[0033] As Figures 1 - 5 shown, two notches 12 distributed vertically are opened at one end of the fluorescent plate 10 away from the flattening roller 3. Both ends of the nylon rope 9 pass through the notches 12 and extend to both sides of the fluorescent plate 10. The upper end of the driving rod 4 is rotatably connected to an L-shaped handle 13 through a pin. The L-shaped handle 13 is used to drive the driving rod 4 to rotate. A groove 14 is opened at the position of the lamp frame 1 corresponding to the L-shaped handle 13. The L-shaped handle 13 is rotatably arranged inside the groove 14. The L-shaped handle 13 is used to drive the driving rod 4 to rotate;

[0034] Principle: The advertising picture 2 is installed by rotating the L-shaped handle 13 to drive the driving rod 4. After the installation is completed, the L-shaped handle 13 is bent 90 degrees, and the L-shaped handle 13 is buckled into the groove 14. At this time, the driving rod 4 is limited by the L-shaped handle 13 and the groove 14 and cannot rotate, ensuring the normal use of the light box. When the advertising picture 2 needs to be replaced, only the L-shaped handle 13 needs to be pulled out. At this time, the driving rod 4 rotates counterclockwise under the turning force of the torsion spring 5, and the advertising picture 2 slides out through the nylon rope 9 and the sliding rod 6.

[0035] As Figures 1 - 5 shown, the principle of the light box provided in this embodiment is as follows:

[0036] During use, the four corners of the advertising picture 2 are clamped by the fixing clips 7, and the L-shaped handle 13 is shaken to drive the driving rod 4 to rotate clockwise. The driving rod 4 winds up the nylon rope 9. At this time, both ends of the nylon rope 9 drive two sliding rods 6 to slide in opposite directions through the traction blocks 8. The advertising picture 2 slides into the lamp frame 1 along with the sliding rod 6 through the flattening roller 3, which can keep the surface of the advertising picture 2 flat. After the installation is completed, the L-shaped handle 13 is bent 90 degrees, and the L-shaped handle 13 is buckled into the groove 14. Only the L-shaped handle 13 needs to be pulled out. At this time, the driving rod 4 rotates counterclockwise under the turning force of the torsion spring 5, and pulls the two sliding rods 6 to slide in the opposite direction through the nylon rope 9, and the advertising picture 2 can slide out automatically. It is not only convenient to install, but also faster to disassemble than the traditional drawer-type light box.
