Description

Technical Field

[0001] This invention relates to the field of advertising light box technology, and in particular to an advertising light box that automatically changes advertising images. Background Technology

[0002] Advertising in a broad sense refers to advertising that is not for profit, such as government announcements, notices, and statements from political parties, religious groups, educational institutions, cultural organizations, municipal bodies, and social groups. Advertising in a narrow sense refers to advertising that is for profit, usually commercial advertising or economic advertising, which is used by businesses to promote their goods or services. Advertising light boxes are excellent devices for advertising.

[0003] Chinese utility model patent document CN209746998U discloses an advertising lightbox with automatic advertising image changing capabilities. The lightbox includes a lightbox body and supporting legs. Supporting legs are fixedly welded to both sides of the lower part of the lightbox body. A viewing window is centrally located at the front of the lightbox body. An advertising scroll is positioned inside the lightbox body corresponding to the viewing window. Bearings are fixedly welded to the upper and lower left sides of the interior of the lightbox body and are rotatably connected to a traction shaft. The traction shaft rotates to change the page layout of the advertising scroll, allowing multiple advertising pages to be displayed simultaneously in one lightbox, switching between different advertisements at different times. An airflow suction pipe removes dust from the interior through various airflow heads, maintaining internal cleanliness.

[0004] However, the aforementioned utility model has the following shortcomings: after the page conversion of the advertising scroll inside the lightbox, it cannot be made to fit snugly against the inner wall of the viewing window, resulting in a gap between the advertising scroll and the viewing window.

[0015] Preferably, the interior of the housing is provided with a second fixing frame, and lamp holders are fixedly connected to the inner walls on both sides of the second fixing frame. The lighting lamp is threadedly connected to the lamp holders, and a set of equally spaced circular holes are provided on one side of the second fixing frame.

[0016] This invention provides an improved advertising lightbox with automatically changing advertising images, which has the following improvements and advantages compared with the prior art:

[0017] Firstly, this invention, through its positioning and transmission components, allows workers to first pull out the telescopic rod at one end of the unwinding roller when installation is required. The worker then inserts the output end of the telescopic rod into the positioning cylinder and secures it with multiple sets of fixing screws. After securing both the unwinding and rewinding rollers, the second motor is activated, driving the rewinding roller to rotate. This rotation causes the advertising poster to move along the outer circumference of the two transmission rollers, thus achieving automatic content replacement. This eliminates the need for manual replacement periodically, meeting user needs. Furthermore, both the unwinding and rewinding rollers are secured with multiple sets of fixing screws, ensuring operational stability and facilitating disassembly and replacement by workers.

[0018] Secondly, this invention, through the displacement component, activates the first motor after the device automatically replaces the advertisement. The first motor effectively drives the threaded screw to rotate. During the rotation of the threaded screw, the threaded sleeve meshing on its outer wall drives the two sets of first fixed frames to move until the advertisement body, which is connected to the outer wall of the two sets of transmission rollers, comes into contact with one side of the outer wall of the glass plate. This avoids a large gap between the glass plate and the advertisement body, which would affect people's viewing of the content, thus satisfying people's viewing needs and improving the overall aesthetics of the device.

[0019] Thirdly, the invention utilizes a heat dissipation component. During prolonged operation of the internal lighting fixtures, significant heat is generated. At this time, a third motor located inside the dust cover is activated, driving a bushing at its output end to rotate. This rotation of the bushing causes the fan blades fixed to its outer wall to rotate as well. The rotation of the fan blades generates airflow, which accelerates the airflow rate inside the cabinet, effectively cooling the lighting fixtures and the advertising poster. This prevents the lighting fixtures from being easily damaged due to prolonged exposure to high temperatures. Furthermore, the dustproof net located on one side of the cabinet is secured within positioning holes using multiple sets of positioning posts, facilitating disassembly and cleaning by staff.

[0031] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] This invention provides an improved advertising lightbox with automatically changing advertising images. The technical solution of this invention is as follows:

[0033] like Figures 1 to 8As shown, this embodiment of the invention provides an advertising lightbox with an automatic advertising image replacement function, including a box body 1. A control panel 2 is fixedly connected to one outer wall of the box body 1. A mounting groove 16 is opened on one side of the box body 1. A glass plate 15 is fixedly connected inside the mounting groove 16. A connecting plate 7 is fixedly connected to one side of the box body 1. A hinge 18 is fixedly connected to one side of the box body 1. A door 8 is fixedly connected to one side of the hinge 18. A heat dissipation component is provided on one side of the door 8. A second motor 9 is fixedly connected to one side of the box body 1. A positioning component is fixedly connected to the output end of the second motor 9. There are two sets of positioning components. The two sets of positioning components are respectively connected to a take-up roller 11 and an unwind roller. An advertising image body 14 is wound around the outer circumference of the take-up roller 11 and the unwind roller. A transmission component is provided inside the box body 1. A displacement component is provided on one side of the transmission component. A lighting lamp 35 is provided inside the box body 1.

[0034] Working principle: The operator first fixes the unwinding roller and the take-up roller 11 to the second motor 9 through the positioning component, and then starts the second motor 9 to make the take-up roller 11 rotate, thereby realizing the automatic replacement of the advertising picture body 14 without the need for manual replacement at regular intervals, which improves the work efficiency.

[0035] Furthermore, the transmission assembly includes a first fixed frame 13 disposed inside the housing 1, with transmission rollers 31 rotatably connected to both sides of the first fixed frame 13, the advertising picture body 14 forming a transmission connection with the transmission rollers 31, and a connecting rod 12 fixedly connected to one side of the first fixed frame 13, with one end of the connecting rod 12 away from the first fixed frame 13 fixedly connected to another first fixed frame 13.

[0036] Working principle: The rotation of the take-up roller 11 allows the advertising poster body 14 to be driven on the outer circumference of the two sets of transmission rollers 31, thus facilitating the viewing of the content of the advertising poster body 14 by the staff through the glass plate 15.

[0037] Furthermore, the positioning assembly includes a connecting plate 26 fixedly connected to the output end of the second motor 9. A positioning cylinder 24 is fixedly connected to one side of the connecting plate 26. A fixing groove 22 is provided at one end of the unwinding roller. A telescopic rod 21 is fixedly connected inside the fixing groove 22. The output end of the telescopic rod 21 is inserted into the inside of the positioning cylinder 24. A through hole is provided on the outer circumference of the positioning cylinder 24. A threaded hole is provided on the outer circumference of the output end of the telescopic rod 21. A fixing screw 25 is threadedly connected inside the threaded hole. A stop post 23 is fixedly connected to the outer circumference of the output end of the telescopic rod 21. A limiting plate 20 is fixedly connected to the outer circumference of the unwinding roller. The diameter of the limiting plate 20 is larger than the diameter of the unwinding roller.

[0038] Working principle: When the operator needs to install the unwinding roller, the telescopic rod 21 located at one end can be pulled out first. Then, the operator inserts the output end of the pulled-out telescopic rod 21 into the positioning cylinder 24 and fixes it with multiple sets of fixing screws 25. After the operator has fixed the unwinding roller and the take-up roller 11, the second motor 9 is started. The second motor 9 can drive the take-up roller 11 to rotate. The rotation of the take-up roller 11 can make the advertising picture body 14 move around the outer circumference of the two sets of transmission rollers 31, thereby realizing the effect of automatic replacement of the content of the advertising picture body 14. There is no need for the operator to manually replace it periodically, which meets the needs of users. At the same time, both the take-up roller 11 and the unwinding roller are fixed with multiple sets of fixing screws 25, which not only ensures their stability during operation, but also makes it easy for the operator to disassemble and replace them.

[0039] Furthermore, the heat dissipation component includes a through groove 3 on one side of the outer wall of the door 8, a dust cover 17 on one side of the outer wall of the door 8, a fixing ear 19 fixedly connected to the outer circumference of the dust cover 17, the fixing ear 19 fixedly connected to one side of the outer wall of the door 8, a rectangular groove 37 on one side of the box body 1, a positioning hole 34 on one side of the outer wall of the box body 1, a positioning post 36 snapped into the inside of the positioning hole 34, and a dustproof net 38 fixedly connected to one end of the positioning post 36.

[0040] Working principle: The rectangular groove 37 on one side of the box 1 and the through groove 3 on the side of the box door 8 enable air circulation inside the box 1, ensuring that the heat generated inside the box 1 is dissipated quickly and preventing heat accumulation inside the box 1 from damaging the lighting lamp 35 and the advertising picture body 14. At the same time, the dust cover 17 and dust net 38 can prevent dust from entering the inside of the box 1 during the heat dissipation process, achieving a good dust prevention effect. The dust net 38 located on one side of the box 1 is fixed inside the positioning hole 34 by multiple sets of positioning posts 36, which makes it convenient for staff to disassemble and clean it.

[0041] Furthermore, a reinforcing rod 30 is fixedly connected to the inner circumference of the dust cover 17, and a third motor 29 is fixedly connected to one end of the reinforcing rod 30. A bushing 28 is provided at the output end of the third motor 29, and fan blades 27 distributed in a circular pattern at equal intervals are fixedly connected to the outer circumference of the bushing 28.

[0042] Working principle: During the long-term operation of the lighting lamp 35 inside the housing 1, a large amount of heat is generated. At this time, the third motor 29 located inside the dust cover 17 starts. The third motor 29 drives the bushing 28 set at its output end to rotate. During the rotation of the bushing 28, the fan blade 27 fixedly connected to its outer wall can also rotate. The rotation of the fan blade 27 can generate wind, thereby accelerating the air flow rate inside the housing 1, which has a good cooling effect on the lighting lamp 35 and the advertising picture body 14, and prevents the lighting lamp 35 from being easily damaged due to being in a high-temperature environment for a long time.

[0043] Furthermore, the displacement assembly includes a first motor 5 fixedly connected to the outer wall of one side of the connecting plate 7. The output end of the first motor 5 is fixedly connected to a threaded screw 4. A threaded sleeve 33 is engaged with the outer circumferential wall of the threaded screw 4. The threaded sleeve 33 is fixedly connected to the first fixed frame 13.

[0044] Working principle: After the equipment automatically replaces the advertising picture body 14, the first motor 5 starts. The first motor 5 can effectively drive the threaded screw 4 to rotate. During the rotation of the threaded screw 4, the threaded sleeve 33 meshing on its outer wall can drive the two sets of first fixed frames 13 to move until the advertising picture body 14, which is connected to the outer wall of the two sets of transmission rollers 31, comes into contact with one side of the outer wall of the glass plate 15. This can avoid the large gap between the glass plate 15 and the advertising picture body 14 affecting people's viewing of its content, meet people's viewing needs, and improve the overall aesthetics of the device.

[0045] Furthermore, a guide post 42 is fixedly connected to one inner wall of the housing 1, and a guide cylinder 41 is sleeved on the outer circumference of the guide post 42. The guide cylinder 41 is fixedly connected to another first fixed frame 13.

[0046] Working principle: The sliding of the guide cylinder 41 on the outer circumference of the guide post 42 can play a good role in limiting and guiding the horizontal movement of the threaded sleeve 33.

[0047] Furthermore, a first fixing frame 6 is fixedly connected to one side of the outer wall of the connecting plate 7, and a diagonal rod is fixedly connected to one side of the first fixing frame 6. The diagonal rod is fixedly connected to the first motor 5.

[0048] Working principle: The first fixed frame 6 and the diagonal bar work together to fix the first motor 5 well, ensuring that the first motor 5 can work stably.

[0049] Furthermore, a second fixing frame 10 is fixedly connected to one side of the housing 1, and the second fixing frame 10 is fixedly connected to the second motor 9.

[0050] Working principle: The second fixing frame 10 can effectively fix the second motor 9, ensuring that the second motor 9 can work stably.
