Description

Technical Field

[0001] The present invention relates to the technical field of luminous advertising, in particular to an advertising light box. Background Art

[0002] Advertising is a marketing method that conveys information to the public through various media. Its core purpose is to promote products, services, brands or concepts in order to influence the audience's cognition, emotions and behaviors. Among them, advertising light boxes are an advertising carrier with a box-type hollow structure and a base material of blister, acrylic, spray-painted cloth, etc. They usually have a built-in light source and luminous properties, which can display advertising content in different scenarios.

[0003] The existing Chinese patent with publication number CN111210741B discloses an advertising light box to solve the problem that traditional light boxes are difficult to meet the installation requirements of advertising papers of different sizes. However, the above patent also has the following defects: First, the advertising paper is inserted into the light box through the installation port. Since the advertising paper is made of soft plastic and is relatively thin, during the insertion process, the advertising paper will not be able to be smoothly inserted into the light box due to static adsorption, which will eventually cause wrinkles on the surface of the advertising paper. Secondly, the installation opening for inserting the advertising paper into the light box is narrow. Therefore, when the advertising paper needs to be replaced later, it is difficult for the operator to remove the advertising paper through the installation opening. In addition, the installation opening of the above-mentioned patent is provided with a canopy. Although the canopy can prevent rainwater from falling into the light box through the installation opening, the canopy will greatly hinder the operator from replacing the advertising paper in the light box through the installation opening. Third, although the above-mentioned patent uses a retractable light box to accommodate advertising papers of different sizes, in actual use, the horizontally extended light box will expand the space it occupies. Therefore, in places with limited space (such as narrow alleys and small shops), in order to ensure the normal extension and retraction of the light box, it may be necessary to dismantle surrounding facilities or re-plan the layout, increasing the cost of site renovation and the difficulty of coordination; in open areas, excessive floor space may cause space waste and reduce site utilization efficiency.

[0004] Therefore, it is necessary to provide an advertising light box to solve the above problems. Summary of the Invention

[0019] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] refer to Figures 1 to 16The advertising light box shown in the figure includes a vertical box body 1, in which advertising paper 2, a light board 3 and a scrolling display assembly are arranged. The scrolling display assembly includes a rotary drive mechanism, a spacing adjustment mechanism, a driving roller shaft 4 and an adjusting roller shaft 5. The rotary drive mechanism includes a driving turntable 6, the lower end of the driving roller shaft 4 is hingedly connected to the driving turntable 6, the spacing adjustment mechanism includes a vertical translation frame 7 and a driven turntable 8 connected to the translation frame 7, and the lower end of the adjusting roller shaft 5 is hingedly connected to the driven turntable 8 The upper end of the driving roller 4 and the adjusting roller 5 are each provided with a split shaft seat 9 for keeping the two vertical. The light board 3 is arranged between the driving roller 4 and the adjusting roller 5. The lower end of the light board 3 is hingedly connected to the box body 1. An elastic hook is provided in the box body 1 for keeping the light board 3 vertical. The advertising paper 2 is annularly sleeved on the driving roller 4 and the adjusting roller 5. A mounting port 10 is provided on one side of the box body 1. A vertical sealing plate 11 is connected to the mounting port 10, and a perspective window 12 is provided on the sealing plate 11.

[0021] The advertising paper 2 used in this device is translucent and has a certain toughness. The outer surface of the advertising paper 2 is printed with information such as text or patterns. During normal advertising playback, the active turntable 6 drives the driving roller 4 to rotate, so that the advertising paper 2 arranged between the driving roller 4 and the adjusting roller 5 will be driven to rotate (there is a certain friction between the advertising paper 2 and the adjusting roller 5 and the driving roller 4, and the annular advertising paper 2 will be tightened by the driving roller 4 and the adjusting roller 5. Therefore, when the driving roller 4 rotates, the adjusting roller 5 will rotate along with the driving roller 4 due to the friction between the advertising paper 2 and the adjusting roller 5). When the advertising paper 2 rotates, the information on the advertising paper 2 will be reciprocatedly displayed through the perspective window 12. The light board 3 provided between the driving roller 4 and the adjusting roller 5 is used to illuminate the advertising paper 2 from the inside out, so that the advertising paper 2 can also display information through the perspective window 12 at night; When replacing the advertising paper 2, first remove the sealing plate 11, and then turn the driving roller 4, the adjusting roller 5 and the light board 3 downward synchronously. During this process, the driving roller 4 and the adjusting roller 5 are changed from a restricted state to a free state by separating the split shaft seat 9, and the light board 3 is changed from a restricted state to a free state by toggling the elastic hook. When the driving roller 4, the adjusting roller 5 and the light board 3 are turned downward and horizontal, the adjusting roller 5 is driven to translate toward the driving roller 4 by the translation frame 7. During this process, the distance between the adjusting roller 5 and the driving roller 4 is gradually reduced, and the advertising paper 2 mounted on the driving roller 4 and the adjusting roller 5 will gradually change from a taut state to a loose state. Thereafter, the loose advertising paper 2 is removed and moved to the driving roller 4 and A new advertising paper 2 is sleeved on the adjusting roller 5. After the new advertising paper 2 is sleeved on the driving roller 4 and the adjusting roller 5, the adjusting roller 5 is driven to translate away from the driving roller 4 by the translation frame 7. During this process, the distance between the adjusting roller 5 and the driving roller 4 gradually increases, so that the advertising paper 2 will be gradually tightened. In the process of horizontal tightening of the advertising paper 2, the advertising paper 2 can be manually flattened to make the advertising paper 2 flat and wrinkle-free. When the advertising paper 2 is completely tightened and flat, the driving roller 4, the adjusting roller 5 and the light board 3 are synchronously flipped upward to be vertical. At this time, the driving roller 4 and the adjusting roller 5 are kept in a vertical state by the merging of the split shaft seat 9, and the light board 3 is kept in a vertical state by the elastic hook. Finally, the sealing plate 11 is connected to the mounting port 10.

[0022] In order to show the specific structure of the rotary drive mechanism, the following features are set: The rotary drive mechanism also includes a mounting seat 13, a fixed platform 14, a reduction motor 15 and a self-locking transmission member. The mounting seat 13 is fixed in the box body 1, and the mounting seat 13 is close to the bottom of the box body 1. The fixed platform 14 is provided on the top of the mounting seat 13. The active turntable 6 is horizontally connected to the fixed platform 14 for rotation. The self-locking transmission member includes a worm gear 16 and a worm 17. The worm gear 16 is coaxially fixed to the active turntable 6. The worm 17 is horizontally connected to the mounting seat 13 for rotation, and the worm 17 is engaged with the worm gear 16. The reduction motor 15 is horizontally fixed to the side of the mounting seat 13, and the output end of the reduction motor 15 is coaxially fixed to the worm 17.

[0023] When the reduction motor 15 is started, the reduction motor 15 will drive the worm wheel 16 to rotate through the worm 17. After the worm wheel 16 rotates, the worm wheel 16 will drive the active turntable 6 to rotate, and finally drive the driving roller shaft 4 to rotate through the active turntable 6. Among them, when the lead angle of the worm 17 is smaller than the friction angle, the transmission between the worm wheel 16 and the worm 17 is self-locking, that is, the worm wheel 16 cannot drive the worm 17 to rotate, thereby preventing the driving roller shaft 4 from rotating by itself.

[0024] In order to show how the lower end of the driving roller shaft 4 is hingedly connected to the driving turntable 6, the following features are set: A vertically upward No. 1 lug 18 is formed on the top of the active turntable 6, a No. 2 lug 19 rotatably connected to the No. 1 lug 18 is formed on the bottom of the driving roller shaft 4, and a No. 1 limit block 20 is formed on the top of the active turntable 6 to limit the rotation of the driving roller shaft 4 by interfering with the No. 2 lug 19.

[0025] The driving roller shaft 4 is hingedly connected to the active turntable 6 by the cooperation of the first lug 18 and the second lug 19. When the reduction motor 15 stops, the position direction of the first lug 18 and the second lug 19 is as follows: Figure 9 As shown, when the split shaft seat 9 above the driving roller shaft 4 is separated, the driving roller shaft 4 can be turned out of the box body 1 through the installation opening 10 on the box body 1 (as shown in FIG. Figure 16 As shown), when the driving roller shaft 4 is turned downward and becomes horizontal, the second lug 19 will contact the first limit block 20 on the active turntable 6 downward, thereby preventing the driving roller shaft 4 from further turning downward through the first limit block 20, ensuring that the driving roller shaft 4 can remain in a horizontal state at this time.

[0026] In order to show the specific structure of the spacing adjustment mechanism, the following features are set: The spacing adjustment mechanism also includes a threaded rod 21, a threaded sleeve 22 and two limit members. The threaded rod 21 is horizontally connected to the inner wall of the box body 1 for rotation. The threaded sleeve 22 is fixedly connected to the translation frame 7, and the threaded sleeve 22 is screwed on the threaded rod 21. One end of the threaded rod 21 passes through the outside of the box body 1. A rotating cap 23 is fixedly connected to the protruding end of the threaded rod 21. The two limit members are symmetrically arranged at the upper and lower parts of the threaded rod 21 respectively. Each limit member includes a limit rod 24 and a sliding sleeve 25. The limit rod 24 is fixedly connected to the inner wall of the box body 1, and the limit rod 24 is parallel to the threaded rod 21. The sliding sleeve 25 is fixedly connected to the translation frame 7, and the sliding sleeve 25 is sleeved on the limit rod 24. The lower end of the translation frame 7 is fixedly provided with a bracket 26, and the driven turntable 8 rotates horizontally on the top of the bracket 26.

[0027] The rotating cap 23 is used for an operator outside the box body 1 to drive the threaded rod 21 inside the box body 1 to rotate. When the threaded rod 21 rotates, the threaded sleeve 22 that cooperates with the thread on the threaded rod 21 drives the translation frame 7 to move horizontally, wherein the cooperation between the sliding sleeve 25 and the limit rod 24 ensures that the translation frame 7 can only be displaced in the horizontal direction.

[0028] In order to improve the stability of the support of the bracket 26, the following features are provided: A support bracket 27 located below the adjusting roller 5 is fixedly provided in the box body 1 . A plurality of support rods 28 parallel to the threaded rod 21 are fixedly provided on the support bracket 27 , and each support rod 28 passes through the bracket 26 horizontally.

[0029] The bracket 26 improves its own support stability through several support rods 28. When the translation frame 7 translates, the bracket 26 will slide on the several support rods 28, so that after the adjustment roller 5 translates, the bracket 26 can always be supported by the several support rods 28.

[0030] In order to show how the lower end of the adjusting roller shaft 5 is hingedly connected to the driven turntable 8, the following features are set: A third lug 29 pointing vertically upward is formed on the top of the driven turntable 8, a fourth lug 30 rotatably connected to the third lug 29 is formed on the bottom of the adjusting roller 5, and a second limit block 31 is formed on the top of the driven turntable 8 to limit the rotation of the adjusting roller 5 by interfering with the fourth lug 30.

[0031] The regulating roller 5 is hingedly connected to the driven turntable 8 by the cooperation of the third lug 29 and the fourth lug 30. When the reduction motor 15 stops, the position direction of the third lug 29 and the fourth lug 30 is as follows: Figure 6 As shown, when the split shaft seat 9 above the adjusting roller shaft 5 is separated, the adjusting roller shaft 5 can be turned out of the box body 1 through the installation opening 10 on the box body 1 (as shown in FIG. Figure 16 As shown in the figure), when the adjusting roller 5 is turned downward and becomes horizontal, the fourth lug 30 will come into contact with the second limit block 31 on the driven turntable 8, thereby preventing the adjusting roller 5 from further turning downward through the second limit block 31, ensuring that the adjusting roller 5 can remain horizontal at this time.

[0032] In order to show the specific structure of the split shaft seat 9, the following features are set: Each split shaft seat 9 includes two semicircular bearings 32 and two semicircular shells 33. Each semicircular bearing 32 is arranged in the corresponding semicircular shell 33. The outer ring of each semicircular bearing 32 is fixedly connected to the semicircular shell 33. The two semicircular shells 33 in one split shaft seat 9 are respectively fixedly connected to the translation frame 7 and the sealing plate 11, and the two semicircular shells 33 in the other split shaft seat 9 are respectively fixedly connected to the box body 1 and the sealing plate 11. The upper ends of the adjusting roller shaft 5 and the driving roller shaft 4 are both formed with a vertical upward rotating shaft 34, and the two semicircular bearings 32 can close together to clamp the corresponding rotating shaft 34.

[0033] When the sealing plate 11 is fixed on the mounting opening 10, the two semicircular shells 33 will respectively drive the two semicircular bearings 32 to close the circular handles towards each other to clamp the corresponding rotating shaft 34, so that the driving roller 4 and the adjusting roller 5 will always remain in a vertical state to drive the advertising paper 2 to rotate. When the sealing plate 11 is removed from the mounting opening 10, the two semicircular bearings 32 will separate, and finally the driving roller 4 and the adjusting roller 5 will change from a restricted state to a free state.

[0034] In order to show how the lower end of the light panel 3 is hingedly connected to the box 1, the following features are set: Two symmetrical support frames 35 are fixed on the inner wall of the box body 1, and a vertically upward No. 5 lug 36 is formed on the top of the support frame 35. Two groups of symmetrical No. 6 lugs 37 are fixed on the bottom of the lamp panel 3, and each group of No. 6 lugs 37 is rotatably connected to the No. 5 lug 36.

[0035] The two support frames 35 are used to support the light board 3. The light board 3 is hingedly connected to the support frames 35 through the cooperation of the fifth lug 36 and the sixth lug 37, so that the light board 3 can be flipped downward and flipped out of the box 1 through the installation port 10.

[0036] In order to show the specific structure of the elastic hook, the following features are set: There are several elastic hook parts, each of which includes a hanging ring 38, a cylindrical sleeve 39, a No. 1 spring 40 and a hook pin.

When the sealing plate 11 needs to be removed from the mounting port 10, the buckle groove 59 on the buckle cover 58 is buckled by hand, and then the locking block 48 is pressed downward with a finger. When the locking block 48 is separated from the locking rod 49 downward, the sealing plate 11 is pulled out. During this process, the pins 57 on the support rod 54 will slide outward in the corresponding slide groove 56, and then the sealing plate 11 is flipped downward. Finally, the sealing plate 11 will be separated from the mounting port 10. When the sealing plate 11 needs to be fixed on the mounting port 10, the sealing plate 11 is flipped upward. When the sealing plate 11 is flipped vertically, the sealing plate 11 is pushed flat into the mounting port 10. When the locking block 48 passes over the locking rod 49, the locking block 48 will be driven by the No. 2 spring 50 to rise again until it is reset. At the same time, the latch 57 will slide to one end of the slide groove 56 and conflict with the inner wall of the slide groove 56. At this time, the sealing plate 11 is restricted from displacing outward from the installation opening 10 by the cooperation between the locking block 48 and the locking rod 49, and the sealing plate 11 is restricted from displacing inward from the installation opening 10 by the cooperation between the latch 57 and the slide groove 56.

[0040] Working principle: The advertising paper 2 used in this device is translucent and has a certain toughness. The outer surface of the advertising paper 2 is printed with information such as text or patterns. During normal advertising playback, the active turntable 6 drives the driving roller 4 to rotate, so that the advertising paper 2 arranged between the driving roller 4 and the adjusting roller 5 will be driven to rotate (there is a certain friction between the advertising paper 2 and the adjusting roller 5 and the driving roller 4, and the annular advertising paper 2 will be tightened by the driving roller 4 and the adjusting roller 5. Therefore, when the driving roller 4 rotates, the adjusting roller 5 will rotate along with the driving roller 4 due to the friction between the advertising paper 2 and the adjusting roller 5). When the advertising paper 2 rotates, the information on the advertising paper 2 will be displayed in sequence through the perspective window 12. The light board 3 provided between the driving roller 4 and the adjusting roller 5 is used to illuminate the advertising paper 2 from the inside out, so that the advertising paper 2 can also display information through the perspective window 12 at night; When replacing the advertising paper 2, first remove the sealing plate 11, and then turn the driving roller 4, the adjusting roller 5 and the light board 3 downward synchronously. During this process, the driving roller 4 and the adjusting roller 5 are changed from a restricted state to a free state by separating the split shaft seat 9, and the light board 3 is changed from a restricted state to a free state by toggling the elastic hook. When the driving roller 4, the adjusting roller 5 and the light board 3 are turned downward and horizontal, the adjusting roller 5 is driven to translate toward the driving roller 4 by the translation frame 7. During this process, the distance between the adjusting roller 5 and the driving roller 4 is gradually reduced, and the advertising paper 2 mounted on the driving roller 4 and the adjusting roller 5 will gradually change from a taut state to a loose state. Thereafter, the loose advertising paper 2 is removed and moved to the driving roller 4 and A new advertising paper 2 is sleeved on the adjusting roller 5. After the new advertising paper 2 is sleeved on the driving roller 4 and the adjusting roller 5, the adjusting roller 5 is driven to translate away from the driving roller 4 by the translation frame 7. During this process, the distance between the adjusting roller 5 and the driving roller 4 gradually increases, so that the advertising paper 2 will be gradually tightened. In the process of horizontal tightening of the advertising paper 2, the advertising paper 2 can be manually flattened to make the advertising paper 2 flat and wrinkle-free. When the advertising paper 2 is completely tightened and flat, the driving roller 4, the adjusting roller 5 and the light board 3 are synchronously flipped upward to be vertical. At this time, the driving roller 4 and the adjusting roller 5 are kept in a vertical state by the merging of the split shaft seat 9, and the light board 3 is kept in a vertical state by the elastic hook. Finally, the sealing plate 11 is connected to the mounting port 10.
