Multiple sets of front clamping plates and multiple sets of rear clamping plates are provided at equal angles on the front and rear sides of the outer surface of the rotating rod. This device is not limited by the length of the connecting line, reduces the height required for lightbox maintenance, improves safety, enhances the stability of the lightbox, and facilitates the installation and disassembly of the lightbox.

[0004] In the above-mentioned technology, when performing maintenance or replacement, it is necessary to turn multiple sets of turntables to rotate multiple sets of threaded tubes, and the threaded rods inside the threaded tubes move out of the fixed screw grooves, thereby removing the light box. The operation is not only cumbersome, but also requires the operation of multiple sets of turntables and threaded tubes one by one, which is time-consuming and reduces the practicality of the device. Utility Model Content

[0005] The purpose of this utility model is to provide a fastening device for advertising light boxes. By using this device, the problem of cumbersome operation and time-consuming operation of multiple turntables and threaded tubes when repairing or replacing light boxes in the prior art is solved.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a fastening device for an advertising lightbox, comprising a mounting plate, a lightbox body disposed at the top of the mounting plate, a connecting plate fixedly connected to one side of the mounting plate, and a connecting rod fixedly connected to the top of the connecting plate. A first clamping plate is fixedly connected to the top of the mounting plate, and a first fixing plate is fixedly connected to the top of the first clamping plate. A groove and a limiting groove are provided on one side of the mounting plate, and a first sliding groove is provided at the top of the mounting plate. The groove communicates with the first sliding groove, and a fixing component is disposed inside the groove.

[0007] The fixing assembly includes a first slider slidably connected inside a first slide groove, a telescopic connecting rod fixedly connected to one side of the first slider, a pull plate fixedly connected to the telescopic end of the telescopic connecting rod, a first spring fixedly connected between the pull plate and the first slider, a limiting block fixedly connected to the pull plate near the first spring, and a fixing frame fixedly connected to the top of the first slider. The limiting block is fitted into a limiting groove, and multiple sets of limiting grooves are provided. A clamping assembly is provided inside the fixing frame.

[0008] Furthermore, the clamping assembly includes a second clamping plate disposed inside the fixed frame, a pull rod fixedly connected to one side of the second clamping plate, a second spring fixedly connected between the second clamping plate and the inner wall of the fixed frame, and a second fixed plate fixedly connected to the top of the second clamping plate. A handle is fixedly connected to one end of the pull rod, and the pull rod moves through the fixed frame.

[0009] Furthermore, a first friction pad is fixedly connected to the inner side of the second clamping plate, and a second friction pad is fixedly connected to the inner side of the first clamping plate.

[0010] Furthermore, a second slider is fixedly connected to the bottom end of the second clamping plate, and a second sliding groove is provided at the bottom end of the inner wall of the fixing frame, with the second slider slidably connected to the second sliding groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This utility model proposes a fastening device for an advertising lightbox. One side of the lightbox body contacts the inner side of the first clamping plate, at which point the first fixing plate contacts the top of the lightbox body. Pulling the pull plate causes the limiting block to move away from one set of limiting grooves. At this time, the telescopic connecting rod and the first spring are both in a stretched state. Moving the pull plate along the groove causes the first slider to slide along the first sliding groove, bringing the fixing frame closer to the lightbox body to complete the fixing of the lightbox body. After fixing, releasing the pull plate causes the limiting block to re-embed into another set of limiting grooves under the reaction force of the first spring, thus fixing the fixing frame and fixing the lightbox body. The entire process only requires simple push-pull actions, without the need for additional tools, significantly reducing the time required for repairing or replacing the lightbox body. This solves the problem of cumbersome operation and time-consuming operation of multiple turntables and threaded tubes when repairing or replacing the lightbox in the prior art.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0023] Combination Figures 1-2 A fastening device for an advertising lightbox includes a mounting plate 1, a lightbox body 2 disposed at the top of the mounting plate 1, a connecting plate 11 fixedly connected to one side of the mounting plate 1, and a connecting rod 111 fixedly connected to the top of the connecting plate 11. A first clamping plate 3 is fixedly connected to the top of the mounting plate 1, and a first fixing plate 31 is fixedly connected to the top of the first clamping plate 3. A groove 12 and a limiting groove 14 are provided on one side of the mounting plate 1, and a first sliding groove 13 is provided at the top of the mounting plate 1. The groove 12 and the first sliding groove 13 are connected, and a fixing component 5 is disposed inside the groove 12.

[0024] The present invention will be further described below with reference to the embodiments. Example

[0025] Please see Figures 1-4 The fixing component 5 includes a first slider 51 slidably connected inside the first slide groove 13, a telescopic connecting rod 52 fixedly connected to one side of the first slider 51, a pull plate 53 fixedly connected to the telescopic end of the telescopic connecting rod 52, a first spring 54 fixedly connected between the pull plate 53 and the first slider 51, a limiting block 55 fixedly connected to the side of the pull plate 53 near the first spring 54, and a fixing frame 56 fixedly connected to the top of the first slider 51. The limiting block 55 is fitted into the limiting groove 14, and multiple sets of limiting grooves are provided. The fixing frame 56 is provided with a clamping component 4, which contacts one side of the light box body 2 with the inner side of the first clamping plate 3. At this time, the first fixing plate 31 and the top of the light box body 2 are in contact. When the ends are in contact, pull the pull plate 53 to make the limiting block 55 leave one of the limiting grooves 14. At this time, the telescopic connecting rod 52 and the first spring 54 are both in a stretched state. Move the pull plate 53 along the groove 12, thereby driving the first slider 51 to slide along the first sliding groove 13, so that the fixing frame 56 is close to the light box body 2 to complete the fixing of the light box body 2. After the fixing is completed, release the pull plate 53. At this time, under the reaction of the first spring 54, the limiting block 55 re-embeds into another set of limiting grooves 14 to fix the fixing frame 56, thereby fixing the light box body 2. The whole process only requires simple push and pull actions, without the need for additional tools, which greatly reduces the time required for maintenance or replacement of the light box body 2.

[0026] The clamping assembly 4 includes a second clamping plate 41 disposed inside the fixed frame 56, a pull rod 42 fixedly connected to one side of the second clamping plate 41, a second spring 43 fixedly connected between the second clamping plate 41 and the inner wall of the fixed frame 56, and a second fixing plate 44 fixedly connected to the top of the second clamping plate 41. A handle 421 is fixedly connected to one end of the pull rod 42. The pull rod 42 moves through the fixed frame 56. When fixing the light box body 2, the inner side of the second clamping plate 41 contacts the light box body 2, and the bottom end of the second fixing plate 44 contacts the top end of the light box body 2. The elastic pressure provided by the second spring 43 helps to maintain a continuous clamping force. When the handle 421 is pulled to move the pull rod 42, the second clamping plate 41 can be moved easily, thereby facilitating the insertion or removal of the light box body 2.

[0027] The inner side of the second clamping plate 41 is fixedly connected to the first friction pad 412, and the inner side of the first clamping plate 3 is fixedly connected to the second friction pad 32. The first friction pad 412 and the second friction pad 32 facilitate the increase of friction between the second clamping plate 41 and the first clamping plate 3 and the light box body 2, so as to improve the stability of clamping.

[0028] The bottom end of the second clamping plate 41 is fixedly connected to the second slider 411. The bottom end of the inner wall of the fixed frame 56 is provided with a second sliding groove 561. The second slider 411 is slidably connected to the second sliding groove 561. When the second clamping plate 41 moves, the second slider 411 slides along the second sliding groove 561, which plays a guiding role.

[0029] A third slide groove 121 is provided at the bottom of the inner wall of the groove 12. The bottom of the first slider 51 is fixedly connected to the third slider 511. The third slider 511 is slidably connected to the third slide groove 121. When the first slider 51 moves, the third slider 511 slides along the third slide groove 121, ensuring that the movement direction of the first slider 51 is precisely controllable.

[0030] Both the limiting block 55 and the limiting groove 14 are regular hexagons. The multiple planes of the regular hexagon provide a larger contact area, which increases the friction between the limiting block 55 and the limiting groove 14. This helps to keep the light box body 2 stable in a fixed state and prevents it from rotating or shifting due to slight external forces.

[0031] Both sides of the pull plate 53 have arc-shaped openings, and a third friction pad 531 is fixedly connected inside the arc-shaped openings. The arc-shaped openings allow the operator's fingers to naturally fit the arc-shaped edge when pulling or pushing the pull plate 53, improving the grip comfort. The third friction pad 531 facilitates the increase of friction between the fingers and the pull plate 53.

[0032] In use, the connecting rod 111 is fixed to the outside to facilitate the fixing of the mounting plate 1. One side of the light box body 2 is brought into contact with the inner side of the first clamping plate 3. At this time, the first fixing plate 31 is in contact with the top of the light box body 2. Pulling the pull plate 53 causes the limiting block 55 to leave one of the limiting grooves 14. At this time, the telescopic connecting rod 52 and the first spring 54 are both in a stretched state. The pull plate 53 is moved along the groove 12, thereby driving the first slider 51 to slide along the first sliding groove 13, so that the fixing frame 56 is close to the light box body 2 to complete the fixing of the light box body 2. After the fixing is completed, the pull plate 53 is released. At this time, under the reaction of the first spring 54, the limiting block 55 is released. Block 55 is re-embedded into another set of limiting grooves 14 to fix the fixing frame 56, thereby fixing the light box body 2. The whole process only requires simple push and pull actions, without the need for additional tools, which greatly reduces the time required for maintenance or replacement of the light box body 2. When fixing the light box body 2, the inner side of the second clamping plate 41 contacts the light box body 2, and the bottom end of the second fixing plate 44 contacts the top end of the light box body 2. The elastic pressure provided by the second spring 43 helps to maintain a continuous clamping force. When the handle 421 is pulled to move the pull rod 42, the second clamping plate 41 can be moved easily, thereby facilitating the insertion or removal of the light box body 2.
