Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figure 1 , Figure 2 and Figure 3 , an LED advertising light box, comprising a main body 1, and a limit component 2 is arranged on one side inside the main body 1;

[0025] The limiting component 2 includes a screw rod 21. A slide rod 22 is installed below the screw rod 21 by bolts on the main body 1, and a motor 23 is installed on the outer wall of one side of the main body 1 by bolts. The thread directions at both ends of the outer wall of the screw rod 21 are opposite, and a moving seat 24 that is slidably connected to the slide rod 22 is threadedly connected to the outer wall of the screw rod 21. A moving groove 25 is formed inside the moving seat 24, and a plurality of springs 26 are fixedly connected inside the moving groove 25. The other end of the spring 26 is fixedly connected to a moving plate 27 that is slidably connected to the inside of the moving groove 25. A pulling plate 28 is installed on the outer wall of one side of the moving plate 27 by bolts, and a limiting plate 29 is installed on the outer wall of one side of the pulling plate 28 by bolts. The motor 23 can provide power for the rotation of the screw rod 21. During the rotation of the screw rod 21, the screw rod 21 can use its threaded connection with the moving seat 24 to move the moving seat 24, and the sliding connection between the moving seat 24 and the slide rod 22 makes the movement of the moving seat 24 more stable. When pulling the pulling plate 28, the pulling plate 28 can drive the moving plate 27 to move. The moving plate 27 can stretch the spring 26, and the limiting plate 29 will be driven during the movement of the pulling plate 28.

[0026] Please refer to Figure 1 、 Figure 2 and Figure 3 The screw rod 21 is movably installed inside the main body 1 through a bearing, and the motor 23 is in transmission connection with the screw rod 21 through a coupling. During the startup of the motor 23, the motor 23 can synchronously drive the screw rod 21 to rotate inside the main body 1 by the action of its output shaft and the coupling; the springs 26 are distributed in an equidistant up-and-down structure, and a baffle 3 is installed on the front outer wall of the main body 1 through a hinge. An installation groove 4 is formed inside the baffle 3. The springs 26 distributed in an up-and-down structure can make the moving plate 27 receive more uniform force during movement, and the setting of the baffle 3 can facilitate the operator to assemble the advertising paper; a transparent plate 5 is arranged inside the installation groove 4, and a pull rod 6 is installed on the outer wall of one side of the front of the baffle 3 by bolts. A soft light plate 7 is installed on the inner side of the main body 1 close to the limiting plate 29 by bolts. The setting of the transparent plate 5 can not only block the entry of dust but also not affect people's observation and processing of the advertising paper. When pulling the pull rod 6, the pull rod 6 can drive the baffle 3 to move.

[0027] Please refer to Figure 2 and Figure 4 On the inner side of the main body 1 close to the soft light plate 7, a disassembly component 8 is arranged. The disassembly component 8 includes an assembly seat 81. An installation plate 82 is slidably connected inside the assembly seat 81. A lighting plate 83 is installed on the outer wall of the front of the installation plate 82 by bolts. The sliding connection between the assembly seat 81 and the installation plate 82 makes the sliding of the installation plate 82 smoother, and the mutual cooperation between the lighting plate 83 and the soft light plate 7 makes the lighting of the advertising paper more uniform.

[0028] Please refer toFigure 4 and Figure 5 , on one side outer wall of the main body 1, a limit seat 84 is installed by bolts, and sliding grooves 85 are opened on both inner walls of the limit seat 84. Plug rods 86 are installed on the bottom inner walls of the sliding grooves 85 by bolts. The opening of the sliding grooves 85 provides an installation position for the installation of the side plates 87, and the setting of the plug rods 86 increases the stability when the side plates 87 are lifted and lowered; a side plate 87 sleeved on the outer wall of the plug rod 86 is slidably connected inside the sliding groove 85, and a circulation groove 88 communicated with the limit seat 84 is opened on one side outer wall of the main body 1. When the side plate 87 is pulled, the side plate 87 will move on the outer wall of the plug rod 86, and by using the mutual communication between the circulation groove 88 and the main body 1, the disassembly of the mounting plate 82 and the lighting plate 83 is made more convenient.

[0029] Working principle: First, the user uses the pull rod 6 and the hinge to open the baffle 3. After the baffle 3 is opened, the user can start the motor 23 according to the width of the advertising paper. The motor 23 will operate on one side of the main body 1, and during the startup of the motor 23, the coupling can be used to drive the screw rod 21 to rotate. During the rotation of the screw rod 21, the screw rod 21 uses the threaded connection with the moving seat 24 to move the moving seats 24 away from or close to each other. During the movement of the moving seats 24, the moving seats 24 will move on the outer wall of the sliding rod 22. When the moving seats 24 move to the designated position, by pulling the pull plate 28, the pull plate 28 will drive the moving plate 27 and the limiting plate 29 to move. During the movement of the moving plate 27, due to the fixed connection with the spring 26, the spring 26 will be stretched. Then, the advertising paper is laid flat on one side of the soft light plate 7. At this time, by releasing the pull plate 28, under the mechanical force of the spring 26, the limiting plate 29 will be driven to fix the advertising paper;

[0030] When the user wants to repair or replace the lighting plate 83, first, by pulling the side plate 87, during the movement of the side plate 87, the side plate 87 will move inside the sliding groove 85, and during the movement of the side plate 87, the side plate 87 will move on the outer wall of the plug rod 86. At this time, the operator can pull the mounting plate 82, and the mounting plate 82 can drive the lighting plate 83 to move inside the main body 1 and the circulation groove 88 by using the sliding connection with the assembly seat 81, so that the lighting plate 83 will exit to the outside of the device, facilitating the operator to replace or maintain the lighting plate 83. The above is the working process of the entire device, and the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0031] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
