Description

Technical Field

[0001] This application relates to the technical field of advertising display, and in particular to an advertising light box and its usage method. Background Technology

[0002] Advertising light boxes are a common advertising display tool, widely used for commercial promotion and information display. They illuminate an image on a transparent material using a light source, making the image bright and eye-catching.

[0003] Advertising light boxes contain advertising light sheets or advertising cloths on which the advertising content to be displayed is printed or sprayed. Some advertising light sheets have anti-counterfeiting features, which prevent them from being reused compared to ordinary advertising light sheets. They are commonly used in shopping malls, exhibitions, corridors, and other high-traffic areas.

[0004] Currently used advertising light panels or advertising cloths are usually glued to the inside of the advertising light box with special adhesive, or directly fixed inside the advertising light box with thumbtacks or other fasteners. When the area of ​​the advertising light panel or advertising cloth is large, these methods are inconvenient for workers to install, thus affecting construction efficiency. Summary of the Invention

[0005] To address the inconvenience of installation when advertising light boxes or advertising cloths are large, this application provides an advertising light box and its usage method.

[0006] On the one hand, this application provides an advertising light box, which adopts the following technical solution:

[0007] An advertising light box, including

[0008] An outer frame, inside which an advertising cloth is placed, and a back panel is provided on the back of the outer frame. The back panel is detachably connected to the outer frame, or a cover that can be flipped open is provided at the bottom of the back panel.

[0009] A transparent panel is provided on the side of the outer frame away from the back panel for displaying the advertising cloth. The outer frame, back panel and transparent panel together enclose a closed space for placing the advertising cloth.

[0010] A movable roller is vertically slidably connected inside the outer frame. The movable roller is rotatably connected to the outer frame and placed parallel to the back panel. The rotation axis of the movable roller is horizontal. One end of the top of the advertising cloth is fixed to the movable roller, and the other end is a free end. A drive component for driving the movable roller is also provided inside the outer frame.

[0011] A fixing component is also provided at the bottom of the outer frame. The advertising cloth is located on the same side of the moving roller and the fixing component. When the top end of the advertising cloth rises to the top with the moving roller, the fixing component is used to fix the free end of the advertising cloth.

[0012] By adopting the above technical solution, when the area of ​​the advertising cloth to be installed is large, the advertising cloth can be rolled into a tube for easy transportation or carrying. In this case, during the installation process, after the worker opens the back panel, only one end of a small section of advertising cloth needs to be pulled out, wrapped around the fixing component, and then flattened on the surface of the moving roller. Then, the moving roller is rotated to flatten the advertising cloth, and the blank content area at one end of the advertising cloth is rolled up on the moving roller. Then, the fixing component is used to hold the remaining unfolded part of the advertising cloth, and the rolled advertising cloth is placed into the outer frame. The drive component is started, so that the moving roller gradually rises. During the rise of the moving roller, it works with the fixing component to gradually unfold the advertising cloth and flatten it until the moving roller reaches the top. At this time, there is still a free end at the bottom of the advertising cloth. The fixing component can be used again to fix the free end of the bottom of the advertising cloth, thereby completing the installation of the advertising cloth. The whole process only requires unfolding a small section of advertising cloth and fixing it on the moving roller, and then the installation of the advertising cloth can be completed automatically. It saves time and effort, is easy to operate, and can effectively improve the installation efficiency of advertising cloth.

[0013] Optionally, both ends of the movable roller are rotatably connected to sliders, and the outer frame is provided with a vertical first slide rail on the inner side wall corresponding to the movable roller. The slider is slidably connected to the first slide rail. The driving assembly includes a lead screw and a driving component. The lead screw is vertically inserted through the slider and threadedly connected to the slider. The driving component is used to drive the lead screw to rotate.

[0014] By adopting the above technical solution, the moving roller is slidably connected to the first slide rail through the sliders at both ends, so that the moving roller can move up and down smoothly. The lead screw passes through the slider and is threadedly connected to the slider. The driving component can drive the lead screw to rotate in both directions, thereby driving the moving roller to move up and down through the slider.

[0015] Optionally, a hinged clamp that can be flipped open is provided on the body of the movable roller. The rotation axis of the clamp is parallel to the movable roller. A placement groove is provided on the body of the movable roller corresponding to the clamp. After the clamp is closed, it abuts against the outer wall of the movable roller.

[0016] By adopting the above technical solution, the clamp can rotate and open relative to the moving roller, and expose the placement groove after opening. The unfolded part of the advertising cloth can be placed in the placement groove. Then the clamp is closed, and the clamp is pressed against the outer wall of the moving roller, so that the unfolded end of the advertising cloth is fixed on the moving roller.

[0017] Optionally, the fixing component includes a flattening roller and a fixing block placed in parallel. The flattening roller presses against the advertising cloth when the moving roller rises. The fixing block is parallel to the moving roller and has a gap between its bottom and the outer frame. The bottom of the fixing block is horizontally slidably connected to the inner wall of the outer frame. The fixing block has a receiving groove on the side near the transparent panel. The flattening roller is located in the receiving groove. A mounting base is also horizontally slidably connected in the receiving groove. Both ends of the flattening roller are rotatably connected to the mounting base and can extend out of the fixing block. An elastic element is provided between the mounting base and the fixing block. The two ends of the elastic element are respectively connected to the inner wall of the mounting base and the fixing block.

[0018] By adopting the above technical solution, the fixed block is slidably connected to the bottom wall of the outer frame. After the moving roller fixes one end of the advertising cloth, the fixed block can be moved so that the flattening roller comes into contact with the advertising cloth, thereby tightening the advertising cloth. Then the moving roller drives one end of the advertising cloth to rise, and the flattening roller comes into contact with the advertising cloth, causing the flattening roller to rotate and continuously flatten the advertising cloth. When the moving roller rises to the top, it can push the fixed block to press the advertising cloth. At this time, the flattening roller is pushed into the receiving groove, and the free end of the advertising cloth is completely pressed by the fixed block.

[0019] Optionally, a second slide rail is provided on the inner bottom wall of the outer frame, and the fixing block is slidably connected to the second slide rail. A limiting member is provided on the second slide rail, and the side wall of the limiting member abuts against the side wall of the fixing block to limit the fixing block.

[0020] By adopting the above technical solution, the fixed block is slidably connected to the second slide rail, which provides guidance for the movement of the fixed block, while the limiting member can limit the position of the fixed block by abutting against the fixed block, so that the fixed block can be kept in any position.

[0021] Optionally, the outer frame is provided with multiple light bars, which are located between the transparent panel and the back panel and are spaced apart in the vertical direction. The light bars are parallel to the moving roller. The two inner sidewalls of the outer frame corresponding to the positions of the light bars are provided with vertical third slide rails. Both ends of the light bars are slidably connected to the third slide rails. The third slide rails are provided with locking components at the positions of the two ends of the light bars to lock the position of the light bars.

[0022] By adopting the above technical solution, the two ends of the lamp stick are slidably connected to the third slide rail, and can move up and down along the third slide rail to adjust its own lighting position. At the same time, the lamp stick can fix its own position through the locking component.

[0023] Optionally, the locking assembly includes a locking screw and a locking pad. The locking screw passes through the third slide rail, and the locking pad is disposed at one end of the locking screw and abuts against the end of the lamp rod to lock the position of the lamp rod.

[0024] By adopting the above technical solution, the locking screw is inserted into the third slide rail. When an external force is applied to twist the locking screw, the locking pad can be pressed against the end of the lamp rod through the locking screw, thereby locking the position of the lamp rod.

[0025] Optionally, a storage roller is provided inside the outer frame. The storage roller is located on the side of the moving roller near the back plate and is parallel to the moving roller. Both ends of the storage roller are rotatably connected to the inner wall of the outer frame and are detachably connected to the outer frame. The storage roller is used to roll up and store the replaced advertising cloth.

[0026] By adopting the above technical solution, when it is necessary to remove the advertising cloth, the fixing component can be removed, the moving roller can be lowered, and at the same time as the moving roller is lowered, the free end of the advertising cloth can be rolled up on the storage roller, so that the removed advertising cloth can be neatly stored and avoid the advertising cloth being too scattered after it is removed.

[0027] On the other hand, this application provides a method for using an advertising light box, which involves installing an advertising cloth using any of the above-described advertising light boxes, including the following steps:

[0028] S1: Remove the back panel, or flip the cover open;

[0029] S2: Pass one end of the advertising cloth to be replaced under the fixed component, then fix one end of the advertising cloth on the moving roller, rotate the moving roller, and wrap one end of the advertising cloth around the moving roller to tighten and flatten the advertising cloth;

[0030] S3: Use the fixing component to abut the lower part of the fixed end of the advertising cloth, then start the drive component to drive the moving roller to rise, and the fixing component to flatten the advertising cloth;

[0031] S4: When the moving roller rises to the top, the drive component stops driving and the fixing component presses against the free end of the advertising cloth to fix the lower part of the advertising cloth.

[0032] S5: Install back panel or cover.

[0033] By adopting the above technical solution, during installation, the staff only needs to pull out one end of a small section of advertising cloth, wrap it around the fixing component, and fix it flat on the surface of the moving roller. Then, rotate the moving roller to flatten the advertising cloth and roll up the blank content area at one end of the advertising cloth onto the moving roller. Then, use the fixing component to hold the remaining unfolded part of the advertising cloth, and place the rolled-up advertising cloth into the outer frame. Start the drive component to make the moving roller gradually rise. During the rise of the moving roller, it works with the fixing component to gradually unfold the advertising cloth and flatten it until the moving roller reaches the top and stops. Finally, use the fixing component to fix the free end of the advertising cloth to complete the entire installation process.

[0034] In summary, this application includes at least one of the following beneficial effects:

[0035] 1. By using a moving roller to move one end of the advertising cloth, when installing the advertising cloth, only a portion of the advertising cloth needs to be unfolded. The moving roller will automatically and gradually unfold the advertising cloth, eliminating the need for additional manpower. The installation process is simple and easy to operate.

[0036] 2. By using fixing blocks and other fixing components to fix the free end of the advertising cloth, and at the same time, the flattening roller can keep the advertising cloth flat during the unfolding process to prevent wrinkles from appearing on the advertising cloth;

[0037] 3. By using a storage roller inside the outer frame, the removed advertising cloth can be immediately rolled up on the storage roller, preventing the advertising cloth from being too scattered after removal. Attached Figure Description

[0044] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0045] Example 1:

[0046] Embodiment 1 of this application discloses an advertising light box, referring to... Figure 1 and Figure 2 The advertising lightbox includes an outer frame 1, which is made of aluminum alloy, possessing the characteristics of being lightweight and high-strength. A back panel 2 is provided on the back of the outer frame 1. The back panel 2 can be directly and detachably connected to the outer frame 1, for example, by means of clips or bolts, allowing the back panel 2 to be completely removed from the back of the outer frame 1. In Embodiment 1 of this application, the upper part of the back panel 2 is fixed to the outer frame 1, while the bottom is hinged to a cover 21 that can be flipped open. The bottom of the cover 21 is hinged to the outer frame 1 via a pivot.

[0047] The back plate 2 is connected to the cover plate 21 by a combination of hinges 22 and pins. The two parts of the hinges 22 are fixed on the back plate 2 and the cover plate 21 respectively. After the cover plate 21 is closed, the two hinges 22 are matched accordingly. Then, the pins are inserted into the two hinges 22 at the same time to realize the connection between the back plate 2 and the cover plate 21.

[0048] An opening is provided on the side of the outer frame 1 away from the back panel 2, and a transparent panel 3 is fixed at the opening. The transparent panel 3 can be made of transparent glass. The transparent panel 3 seals the opening, and the outer frame 1, the back panel 2, and the transparent panel 3 together form a closed space, which is used to place the advertising cloth 4.

[0049] Reference Figure 2 and Figure 3 Inside the outer frame 1, a movable roller 5 is vertically slidably connected. The movable roller 5 is placed parallel to the back plate 2. Two vertical first slide rails 11 are fixed on the inner wall of the outer frame 1 corresponding to the position of the movable roller 5. The movable roller 5 can slide up and down along the first slide rails 11.

[0050] A hinged clamping plate 51 that can be flipped open is hinged to the roller body of the movable roller 5. The two ends of the clamping plate 51 are rotatably connected to the movable roller 5 via rotating shafts, and the rotation axis of the clamping plate 51 is parallel to the movable roller 5. A placement groove 52 is provided on the roller body of the movable roller 5 corresponding to the clamping plate 51. After the clamping plate 51 is closed on the movable roller 5, the clamping plate 51 is exactly closed in the placement groove 52, forming a complete whole with the movable roller 5.

[0051] Before installation, the advertising cloth 4 is rolled into a tube shape for easy transportation or carrying. When it is necessary to install the advertising cloth 4, a small section of one end of the advertising cloth 4 can be pulled out, the clamp 51 can be opened, and the pulled-out section of advertising cloth 4 can be placed in the placement groove 52. Then the clamp 51 can be closed, and the clamp 51 can be 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. Then the one end of the advertising cloth 4 can be gradually unfolded as the moving roller 5 rises.

[0052] Reference Figure 3 and Figure 4To drive the movable roller 5 to slide up and down, sliders 53 are rotatably connected to both ends of the movable roller 5. The sliders 53 are slidably connected within the first slide rail 11. A lead screw 54 is threaded through and connected to the slider 53. The lead screw 54 is placed vertically, with its top end rotatably connected to the inner wall of the outer frame 1. A drive component 55, which can be a small servo motor, is provided at the bottom of the lead screw 54. The bottom of the drive component 55 is fixed to the inner wall of the outer frame 1, and its output shaft is coaxially fixed to one end of the bottom of the lead screw 54. The drive component 55 drives the lead screw 54 to rotate, thereby driving the slider 53 to move along the first slide rail 11, thus causing the movable roller 5 to move smoothly. The drive component 55 can also drive the lead screw 54 to rotate in both directions, thereby driving the movable roller 5 to move up and down through the slider 53, achieving the purpose of unfolding or removing the advertising cloth 4.

[0053] Reference Figure 2 and Figure 3 To further restrict the free end of the lower part of the advertising cloth 4, a fixing component 6 is also provided at the bottom inside the outer frame 1. 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 there is a gap between its bottom and the outer frame 1. A horizontal receiving groove 621 is opened on the side of the fixing block 62 near the transparent panel 3, and the flattening roller 61 is located in the groove of the receiving groove 621. A mounting base 63 is also horizontally slidably connected in the receiving groove 621. Both ends of the flattening roller 61 are rotatably connected to the mounting base 63. When the flattening roller 61 moves with the mounting base 63, part of the roller body can extend out of the fixing block 62 and contact the advertising cloth 4. An elastic element 64 is provided between the mounting base 63 and the fixing block 62. The elastic element 64 can be a compression spring, and both ends of the elastic element 64 are fixedly connected to the inner walls of the mounting base 63 and the fixing block 62, respectively.

[0054] In order to make the advertising cloth 4 more flat by using the flattening roller 61, 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 block 12 is wider than that of the transparent panel 3. The flattening roller 61 can directly abut against the inner wall of the abutment block 12, and the advertising cloth 4 can pass between the flattening roller 61 and the abutment block 12, so that the advertising cloth 4 can be flattened when passing through the flattening roller 61.

[0055] A second slide rail 13 is fixed to the inner bottom wall of the outer frame 1. A fixing 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, multiple bolt holes are opened on the second slide rail 13, and the limiting member 131 can be inserted into the bolt holes. The side wall of the limiting member 131 abuts against the side wall of the fixing block 62, thereby limiting the position of the fixing block 62. In Embodiment 1 of this application, the limiting member 131 is a magnetic block, so that the limiting member 131 can be freely adjusted and attached to any position on the second slide rail 13 according to the position of the fixing block 62, thereby limiting the position of the fixing block 62.

[0056] After the movable roller 5 fixes one end of the advertising cloth 4, the movable fixing block 62 is moved so that the flattening roller 61 comes into contact with the advertising cloth 4, and the flattening roller 61 presses the advertising cloth 4 against the abutment block 12, thereby tightening and flattening the advertising cloth 4. Then the movable roller 5 drives one end of the advertising cloth 4 to rise, and the flattening roller 61 comes into contact with the advertising cloth 4, so that the flattening roller 61 follows the rotation through friction, continuously flattening the advertising cloth 4. When the movable roller 5 rises to the top, it can push the fixing block 62 to press the advertising cloth 4. At this time, the flattening roller 61 is pushed into the receiving groove 621, and the free end of the advertising cloth 4 is completely pressed by the fixing block 62. The limiting member 131 limits the fixing block 62, so that the position of the advertising cloth 4 is fixed.

[0057] Reference Figure 2 and Figure 4 The outer frame 1 contains multiple light bars 7, the number of which can be determined according to the specific size of the advertising lightbox. All light bars 7 are located between the transparent panel 3 and the back panel 2, and are spaced vertically, with all light bars 7 parallel to the moving roller 5. Vertical third slide rails 14 are fixed to the two inner sidewalls of the outer frame 1 corresponding to the positions of the light bars 7, and both ends of the light bars 7 are slidably connected to the third slide rails 14.

[0058] A locking screw 142 is threaded onto and connected to the third slide rail 14. A locking pad 141 is located inside the third slide rail 14, fixed to one end of the locking screw 142, and in contact with the end of the lamp rod 7. When an external force is applied to rotate the locking screw 142, the locking screw 142 pushes the locking pad 141 against the end of the lamp rod 7, thereby restricting the position of the lamp rod 7. The two ends of the lamp rod 7 are slidably connected within the third slide rail 14, allowing the lamp rod 7 to move up and down along the third slide rail 14, thus facilitating adjustment of its lighting position.

[0059] When the area of ​​the advertising cloth 4 to be installed is large, the advertising cloth 4 can be rolled into a tube for easy transportation or carrying. In this case, during the installation process, after the staff opens the back plate 2, they only need to pull out a small section of the advertising cloth 4 from one end, pass it under the fixing block 62, and fix it flat on the surface of the moving roller 5 through the clamp 51. Then, rotate the moving roller 5 to flatten the advertising cloth 4 and roll the blank content area of ​​one end of the advertising cloth 4 onto the moving roller 5. Then, use the flattening roller 61 to hold the remaining unfolded part of the advertising cloth 4, and put the rolled advertising cloth 4 into the outer frame 1. Start the drive component 55 to make the moving roller 5 gradually rise. During the rise of the moving roller 5, it cooperates with the flattening roller 61 to gradually unfold the advertising cloth 4 and flatten the unfolded advertising cloth 4 until the moving roller 5 rises to the top and stops. At this time, there is still a free end at the bottom of the advertising cloth 4. The free end at the bottom of the advertising cloth 4 can be fixed again by the moving fixing block 62, thereby completing the installation of the advertising cloth 4. The entire process only requires unfolding a small section of the advertising cloth 4 and fixing it to the moving roller 5. The installation of the advertising cloth 4 is then completed automatically, saving time and effort while being easy to operate, effectively improving the installation efficiency of the advertising cloth 4. Removing the advertising cloth 4 is simply a matter of reversing the installation process.

[0060] The implementation principle of an advertising lightbox in Embodiment 1 of this application is as follows: one end of the advertising cloth 4 is fixed to the moving roller 5 by the clamp 51. 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 fixing block 62 is pushed to press against the free end of the advertising cloth 4, thereby completely restricting the position of the advertising cloth 4. The whole installation process is convenient and quick, and even a large area of ​​advertising cloth 4 can be easily installed.

[0061] Example 2:

[0062] The difference between Example 2 and Example 1 is that: (Refer to...) Figure 5 The outer frame 1 also includes a storage roller 15, which is located on the side of the moving roller 5 away from the transparent panel 3 and is parallel to the moving roller 5. Both ends of the storage roller 15 are rotatably connected to the inner wall of the outer frame 1 and are detachably connected to the outer frame 1. The detachable connection can be achieved by snap-fitting, with slots provided on the inner wall of the outer frame 1 at the positions corresponding to the storage roller 15, and both ends of the storage roller 15 snapped into and rotated within the slots.

[0063] When it is necessary to remove the advertising cloth 4, the fixing block 62 can be removed and the moving roller 5 can be lowered. At the same time as the moving roller 5 is lowered, the free end of the advertising cloth 4 is rolled up on the storage roller 15 and the storage roller 15 is rotated synchronously so that the removed advertising cloth 4 can be neatly stored and avoid the advertising cloth 4 being too scattered after removal.

[0064] Example 3:

[0065] Embodiment 3 of this application discloses a method for using an advertising lightbox, which involves installing an advertising cloth 4 using the advertising lightbox described in Embodiments 1 and 2, specifically including the following steps:

[0066] S1: Roll up the advertising cloth 4 to be installed into a tube, remove the back panel 2, or flip open the cover 21 and put the advertising cloth 4 into the outer frame 1.

[0067] S2: Pull out a small section from one end of the advertising cloth 4 to be replaced, and pass this small section around under the fixing block 62. Then fix the pulled-out end of the advertising cloth 4 to the moving roller 5 through the clamp 51. Rotate the moving roller 5 to wind one end of the advertising cloth 4 onto the moving roller 5, and tighten and flatten the advertising cloth 4.

[0068] S3: Move the fixed block 62 so that the flattening roller 61 presses the lower part of the fixed end of the advertising cloth 4 against the abutment block 12. Then start the drive component 55 to drive the moving roller 5 to rise, while the flattening roller 61 flattens the advertising cloth 4.

[0069] S4: When the moving roller 5 rises to the top, the drive component 55 stops driving and pushes the fixing block 62 to press against the free end of the advertising cloth 4 to fix the lower part of the advertising cloth 4, thus completing the installation of the advertising cloth 4.

[0070] S5: Install backplate 2 or cover plate 21.

[0071] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
