Two vertical first slide rails 11 are fixed to the inner wall of the outer frame 1 at positions corresponding to the moving roller 5. The moving roller 5 can slide up and down along the first slide rails 11.

[0032] A clamping plate 51 that can be flipped open is hinged on the roller body of the moving roller 5. Both ends of the clamping plate 51 are rotatably connected to the moving roller 5 through a rotating shaft, and the rotation axis of the clamping plate 51 is parallel to the moving roller 5. A placement groove 52 is opened on the roller body of the moving roller 5 corresponding to the clamping plate 51. After the clamping plate 51 is covered on the moving roller 5, the clamping plate 51 just covers the placement groove 52 and forms a complete whole with the moving roller 5.

[0033] Before installation, the advertising cloth 4 is rolled into a tube shape, which is convenient for transportation or carrying. When the advertising cloth 4 needs to be installed, a small section of the advertising cloth 4 can be pulled out, the clamping plate 51 is opened, and the pulled-out small section of the advertising cloth 4 is placed in the placement groove 52, and then the clamping plate 51 is closed, and the clamping plate 51 is pressed against the outer wall of the moving roller 5, so that the unfolded end of the advertising cloth 4 is fixed on the moving roller 5, and then the end of the advertising cloth 4 can follow the moving roller 5 to rise and be gradually unfolded.

[0034] Reference Figure 3 and Figure 4In order to drive the moving roller 5 to slide up and down, both ends of the moving roller 5 are rotatably connected with a slider 53, and the slider 53 is slidably connected to the first slide rail 11. A screw rod 54 is inserted and threadedly connected in the slider 53. The screw rod 54 is placed vertically. The top of the screw rod 54 is rotatably connected to the inner wall of the outer frame 1. A driving member 55 is provided at the bottom of the screw rod 54. The driving member 55 can be a small servo motor. The bottom of the driving member 55 is fixed to the inner wall of the outer frame 1, and the output shaft of the driving member 55 is coaxially fixed with one end of the bottom of the screw rod 54. The driving member 55 drives the screw rod 54 to rotate, thereby driving the slider 53 to move along the first slide rail 11, thereby driving the moving roller 5 to move smoothly. The driving member 55 can drive the screw rod 54 to rotate forward and reverse, thereby driving the moving roller 5 to move up and down through the slider 53, so as to achieve the purpose of unfolding or removing the advertising cloth 4.

[0035] Reference Figure 2 and Figure 3 In order to further limit the free end of the lower part of the advertising cloth 4, a fixing component 6 is also provided at the bottom of the outer frame 1, and the fixing component 6 is located below the moving roller 5. The fixing component 6 includes a flattening roller 61 and a fixing block 62 placed in parallel. The fixing block 62 is parallel to the moving roller 5, and a gap is left between the bottom and the outer frame 1. A horizontal receiving groove 621 is provided on the side of the fixing block 62 close to the transparent panel 3, and the flattening roller 61 is located in the notch of the receiving groove 621. A mounting seat 63 is also horizontally slidably connected in the receiving groove 621, and both ends of the flattening roller 61 are rotatably connected to the mounting seat 63. When the flattening roller 61 moves with the mounting seat 63, part of the roller body can be extended out of the fixing block 62 and contact the advertising cloth 4. An elastic member 64 is provided between the mounting seat 63 and the fixing block 62, and the elastic member 64 can be a compression spring, and the two ends of the elastic member 64 are respectively fixedly connected to the mounting seat 63 and the inner wall of the fixing block 62.

[0036] In order to utilize the flattening roller 61 to better unfold the advertising cloth 4 to be more flat, the outer frame 1 is fixed with abutment blocks 12 at the top and bottom of the transparent panel 3 respectively. The thickness of the abutment blocks 12 is wider than that of the transparent panel 3. The flattening roller 61 can directly abut against the inner wall of the abutment blocks 12, and the advertising cloth 4 can pass between the flattening roller 61 and the abutment blocks 12, so that the advertising cloth 4 can be flattened when passing through the flattening roller 61.

[0037] The second slide rail 13 is fixed to the inner bottom wall of the outer frame 1, and the fixed block 62 is slidably connected to the second slide rail 13. A limiting member 131 is provided on the second slide rail 13. The limiting member 131 can be a fastening bolt. At the same time, a plurality of bolt holes are provided on the second slide rail 13. The limiting member 131 can be inserted into the bolt holes.

In the embodiment 1 of the present application, the limiting member 131 is a magnet block, so that the limiting member 131 can be freely adjusted to be adsorbed on any position of the second slide rail 13 according to the position of the fixed block 62, thereby limiting the position of the fixed block 62.

[0038] After the moving roller 5 fixes one end of the advertising cloth 4, the fixed block 62 can be moved so that the flattening roller 61 contacts the advertising cloth 4, and the flattening roller 61 presses the advertising cloth 4 and presses it against the abutment block 12, thereby tightening and flattening the advertising cloth 4. Then the moving roller 5 drives one end of the advertising cloth 4 to rise, and the flattening roller 61 contacts the advertising cloth 4, so that the flattening roller 61 follows the rotation through friction and continuously flattens the advertising cloth 4. When the moving roller 5 rises to the top, the fixed block 62 can be pushed to press the advertising cloth 4. At this time, the flattening roller 61 is pushed into the accommodating groove 621, and the free end of the advertising cloth 4 is completely pressed by the fixed block 62, and the fixed block 62 is limited by the limiting member 131, so that the position of the advertising cloth 4 is fixed.

[0039] Reference Figure 2 and Figure 4 , multiple light sticks 7 are arranged inside the outer frame 1, and the number of light sticks 7 can be determined according to the specific size of the advertising light box. Multiple light sticks 7 are located between the transparent panel 3 and the back panel 2, and are spaced apart in the vertical direction, and all light sticks 7 are parallel to the moving roller 5. Vertical third slide rails 14 are fixed on the two inner side walls of the outer frame 1 corresponding to the positions of the light sticks 7, and both ends of the light stick 7 are slidably connected to the third slide rails 14.

[0040] A locking screw 142 is threadedly provided on the third slide rail 14, and a locking pad 141 is provided inside the third slide rail 14. The locking pad 141 is fixed to one end of the locking screw 142, and the locking pad 141 contacts the end of the lamp bar 7. When an external force is applied to rotate the locking screw 142, the locking screw 142 pushes the locking pad 141 to press against the end of the lamp bar 7, thereby limiting the position of the lamp bar 7. Both ends of the lamp bar 7 are slidably connected in the third slide rail 14, so that the lamp bar 7 can move up and down along the third slide rail 14, thereby facilitating the adjustment of its own lighting position.

[0041] When the area of ​​the advertising cloth 4 to be installed is large, the advertising cloth 4 can be rolled up into a tube for easy transportation or carrying. At this time, during the installation process, after the staff opens the back plate 2, they only need to pull out one end of a small section of the advertising cloth 4, pass it around the bottom of the fixed block 62, and fix it flatly on the surface of the moving roller 5 through the clamping plate 51, and then rotate the moving roller 5 to flatten the advertising cloth 4, and roll up the blank content area at one end of the advertising cloth 4 on the moving roller 5, and then use the flattening roller 61 to abut the remaining unfolded part of the advertising cloth 4, and put the rolled advertising cloth 4 into the outer frame 1, start the driving member 55, so that the moving roller 5 gradually rises, and the moving roller 5 cooperates with the flattening roller 61 during the rising process to gradually unfold the advertising cloth 4, and also flatten the unfolded advertising cloth 4, until the moving roller 5 rises to the top and stops, at this time, the remaining part of the bottom end of the advertising cloth 4 is a free end, and the free end of the bottom of the advertising cloth 4 can be fixed by the moving fixed block 62 again, thereby completing the installation of the advertising cloth 4. The whole process only requires unfolding a small section of the advertising cloth 4 and fixing it on the moving roller 5, and then the installation process of the advertising cloth 4 can be automatically completed, which saves time and effort, is easy to operate, and can effectively improve the installation efficiency of the advertising cloth 4. To remove the advertising cloth 4, only the opposite steps of installing the advertising cloth 4 need to be performed to remove the advertising cloth 4.

[0042] The implementation principle of an advertising light box in Example 1 of the present application is as follows: one end of an advertising cloth 4 is fixed on a moving roller 5 by a clamping plate 51, and the moving roller 5 drives the advertising cloth 4 to rise. While the advertising cloth 4 rises, the flattening roller 61 gradually flattens the advertising cloth 4 to ensure that there are no wrinkles after the advertising cloth 4 is unfolded. When the advertising cloth 4 is fully unfolded, the fixed block 62 is pushed to press against the free end of the advertising cloth 4, thereby completely limiting the position of the advertising cloth 4. The entire installation process is convenient and quick, and even a larger advertising cloth 4 can be easily installed.

[0043] Embodiment 2: The difference between Example 2 and Example 1 is that: Figure 5 A storage roller 15 is also provided in the outer frame 1. The storage roller 15 is located on the side of the moving roller 5 away from the transparent panel 3 and is parallel to the moving roller 5.
