Description

Technical Field

[0001] This utility model relates to the field of advertising box technology, specifically to an advertising light box. Background Technology

[0002] Advertising light boxes are frequently installed in cities, subways, streets, residential areas, squares, parking lots, etc., for advertising purposes. The advertising banners inside these light boxes need to be replaced regularly to ensure timely updates of the advertisements. When installing or replacing internal parts of the light box, the light box cover needs to be opened to access the interior for operation.

[0003] The existing light boxes only have one gas spring for operational safety protection after opening. Since some light boxes are located outdoors, the gas spring is prone to failure during long-term use, which will cause the light box cover to fall rapidly. If workers are working during the fall, it can easily cause injury to them, resulting in low safety.

[0004] Therefore, it is necessary to invent an advertising lightbox to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an advertising light box to solve the problem that the gas spring in the existing light box is prone to failure after long-term use, which leads to the inability to support the light box cover and the light box cover falling down quickly. If workers are working during the falling process, it can easily cause injury to the workers, resulting in low safety.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an advertising light box, comprising a light box body, a light-emitting back plate fixedly connected inside the light box body, a sealing frame hinged to the upper front end of the light box body, a visible panel fixedly connected to the inner side of the sealing frame, and support components provided on both the left and right sides between the light box body and the sealing frame, the support components including a linear guide rail, a linear slide groove, a linear slider, a first mounting base, a support rod, a second mounting base, and a locking block.

[0007] By adopting the above technical solution, the advertising paper is fixed on the front side of the light-emitting back panel. At this time, the light-emitting back panel illuminates the advertising paper from the rear. The rear end of the sealing frame rotates around the upper end of the light box body to open or seal the light box body. After the sealing frame seals the front side of the light box body, the advertising paper inside the light box body can be seen through the visible panel. When the sealing frame rotates upward and rises, the support component provides mechanical support for the sealing frame to improve the support strength.

[0008] Optionally, multiple sets of first mounting seats are fixedly connected to the upper surfaces of the two sets of linear guides. The first mounting seats are fixedly connected to the lower surface of the sealing frame, and the locking block is fixedly connected to a position slightly behind the center of the linear guide.

[0009] By adopting the above technical solution, multiple sets of first mounting seats work together to firmly fix the linear guide rail to the surface of the sealing frame.

[0010] Optionally, both the linear guide rail and the locking block have linear grooves on their sides, and the linear slider is slidably connected to the linear grooves.

[0011] By adopting the above technical solution, during the opening and closing of the sealing frame, the linear slider slides inside the linear groove. When the sealing frame rotates to 90°, the linear slider will slide to the rear side of the locking block, and the locking block will limit the front side of the linear slider.

[0012] Optionally, the two sets of second mounting seats are fixedly connected to the inner walls of the left and right sides of the light box body, respectively, the lower end of the support rod is rotatably connected to the second mounting seat, and the upper end of the support rod is slidably connected to the side of the linear slider.

[0013] By adopting the above technical solution, the support rods on both sides are used to support the sealing frame.

[0014] Optionally, the locking block includes a positioning groove, a limiting groove, a connecting hole, a plug-in groove, a positioning block, a slide rod, a limiting plate, a locking spring, and a plug-in block.

[0015] Optionally, the positioning groove is located inside the locking block on the side of the linear slide groove. The positioning block is slidably connected to the positioning groove. Two sets of insertion grooves are provided between the positioning groove and the linear slide groove. Insertion blocks are slidably connected inside both sets of insertion grooves. The insertion blocks are fixedly connected to the positioning block.

[0016] By adopting the above technical solution, the positioning block slides inside the positioning groove, the insertion block slides inside the insertion groove, and the front side of the insertion block at one end of the straight slide groove is an arc surface.

[0017] Optionally, the limiting groove is located inside the locking block on the upper side of the linear slide groove. Both ends of the limiting groove are provided with connecting holes. The slide rod is slidably connected to the connecting holes. A limiting plate is fixedly connected to the surface of the slide rod. The limiting plate is slidably connected to the limiting groove. One end of the inner side of the slide rod is fixedly connected to the positioning block.

[0018] By adopting the above technical solution, the slide rod slides inside the connecting hole, thereby driving the limiting plate to slide inside the limiting groove, and thus adjusting the position of the positioning block.

[0019] Optionally, the locking spring is sleeved on the surface of the slide rod, and the two ends of the locking spring abut against the side walls of the limiting plate and the limiting groove, respectively.

[0020] By adopting the above technical solution, the locking spring is used to push one end of the slide rod, and then the positioning plate makes one end of the plug block lock inside the straight slide groove.

[0021] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0022] 1. In the process of opening the sealing frame, the linear slider slides backward inside the linear groove. When the sealing frame rotates to 90°, the linear slider slides to the rear side of the locking block. The locking block limits the front side of the linear slider. At this time, the linear slider, the support rod and the second mounting seat work together to fix the angle of the sealing frame, which improves the stability of the sealing frame after it is opened, and thus effectively improves the safety of the advertising paper replacement process.

[0023] 2. This utility model improves the ease of opening by setting one end of the plug-in block to an arc surface, allowing the linear slider to slide directly over the plug-in block. During the closing process, the two sliding rods press inward simultaneously to retract the plug-in block into the plug-in slot, unlocking the rear side of the linear slider. At this time, the sealing frame can be rotated downward, thereby improving the stability of the sealing frame and the ease of opening and closing it. Attached Figure Description

[0032] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0033] This utility model provides, for example Figures 1 to 4 An advertising lightbox is shown, including a lightbox body 1. A light-emitting backplate 11 is fixedly connected inside the lightbox body 1. A sealing frame 12 is hinged to the upper front end of the lightbox body 1. A visible panel 13 is fixedly connected to the inner side of the sealing frame 12. Support components 2 are provided on both the left and right sides between the lightbox body 1 and the sealing frame 12. The support components 2 include a linear guide rail 21, a linear slide 22, a linear slider 23, a first mounting base 24, a support rod 25, a second mounting base 26, and a locking block 27.

[0034] The visible panel 13 is made of acrylic material, and the light-emitting back panel 11 is connected to a power source for illumination, making it easy to view the advertising paper inside the lightbox body 1 at night through the visible panel 13. During the replacement of the advertising paper, the sealing frame 12 is first rotated upward. When the sealing frame 12 is rotated to 90°, the support component 2 will automatically lock to support the sealing frame 12, thereby improving the stability of the sealing frame 12 and improving operational safety.

[0035] See Figure 2 and Figure 3 Multiple sets of first mounting seats 24 are fixedly connected to the upper surfaces of the two sets of linear guide rails 21. The first mounting seats 24 are fixedly connected to the lower surface of the sealing frame 12. The locking block 27 is fixedly connected to the rear part of the middle of the linear guide rail 21. Linear grooves 22 are provided on the sides of both the linear guide rail 21 and the locking block 27. The linear slider 23 is slidably connected to the linear grooves 22. Two sets of second mounting seats 26 are fixedly connected to the inner walls of the left and right sides of the light box body 1, respectively. The lower end of the support rod 25 is rotatably connected to the second mounting seat 26, and the upper end of the support rod 25 is slidably connected to the side of the linear slider 23.

[0036] Specifically, since the second mounting base 26 is fixed and the length of the support rod 25 is fixed, when the sealing frame 12 rotates upward, the support rod 25 will drive the linear slider 23 to slide backward inside the linear groove 22. When the sealing frame 12 rotates to 90°, the linear slider 23 will slide to the rear side of the locking block 27. The locking block 27 limits the front side of the linear slider 23 to prevent the linear slider 23 from sliding forward. At this time, the linear slider 23, the support rod 25 and the second mounting base 26 cooperate to provide rigid support for the sealing frame 12. When the locking block 27 is not unlocked, the sealing frame 12 always remains stable and will not be affected by the external environment.

[0037] See Figures 4 to 6 The locking block 27 includes a positioning groove 271, a limiting groove 272, a connecting hole 273, a plug-in groove 274, a positioning block 275, a slide rod 276, a limiting plate 277, a locking spring 278, and a plug-in block 279. The positioning groove 271 is located inside the locking block 27 on the side of the linear slide groove 22. The positioning block 275 is slidably connected to the positioning groove 271. Two sets of plug-in grooves 274 are provided between the positioning groove 271 and the linear slide groove 22. Plug-in blocks 279 are slidably connected inside each set of plug-in grooves 274. The plug-in blocks 279 are connected to the positioning block 275. The fixed connection includes a limiting groove 272 located inside the locking block 27 on the upper side of the linear slide groove 22. Both ends of the limiting groove 272 have connecting holes 273. The slide rod 276 is slidably connected to the connecting holes 273. A limiting plate 277 is fixedly connected to the surface of the slide rod 276. The limiting plate 277 is slidably connected to the limiting groove 272. One end of the inner side of the slide rod 276 is fixedly connected to the positioning block 275. A locking spring 278 is sleeved on the surface of the slide rod 276. Both ends of the locking spring 278 abut against the side walls of the limiting plate 277 and the limiting groove 272, respectively.

[0038] In addition, under the action of the locking spring 278, the locking spring 278 automatically pushes the limiting plate 277 outward, and then slides outward through the slide rod 276. The slide rod 276 drives the positioning block 275 and the plug block 279 to slide outward, thereby placing one end of the plug block 279 inside the straight slide groove 22.

[0039] As the linear slider 23 slides backward inside the linear groove 22, since the front side of the outer end of the plug block 279 is curved, when the linear slider 23 contacts the plug block 279, it will automatically push the plug block 279 into the insertion groove 274, thereby causing the linear slider 23 to automatically slide to the rear side of the plug block 279. At this time, under the action of the locking spring 278, the plug block 279 will automatically pop out and lock the front side of the linear slider 23.

[0040] When the sealing frame 12 needs to be rotated downwards, the sliding rods 276 on both sides are pressed inwards at the same time. The sliding rods 276 on both sides automatically slide the plug block 279 into the plug slot 274, thereby unlocking the front side of the linear slider 23. At this time, the linear slider 23 can slide forward, thereby allowing the sealing frame 12 to rotate downwards and seal the front side of the light box body 1.

[0041] The working principle of this utility model is as follows: During the opening of the sealing frame 12, the linear slider 23 slides backward inside the linear groove 22. When the sealing frame 12 rotates to 90°, the linear slider 23 will slide to the rear side of the locking block 27. The locking block 27 limits the front side of the linear slider 23. At this time, the linear slider 23, the support rod 25, and the second mounting base 26 cooperate to fix the angle of the sealing frame 12, thereby improving the stability of the sealing frame 12 after opening and effectively improving the safety during the replacement of advertising paper. Moreover, the support components 2 are all metal structures and are not easily affected by the external environment.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
