[0010] Beneficial effects

[0011] This utility model provides an adjustable-angle display board. It offers the following advantages: The adjustable-angle display board utilizes a worm gear, worm wheel, and protective shell. A drive device rotates the worm gear, and the meshing of the worm gear and worm wheel causes the worm wheel to rotate the display board within the fixed frame, thus changing the angle of the display board. This solves the problem that adjusting the display direction or angle of existing display boards often requires moving the display board or disassembling and reinstalling it entirely, resulting in a cumbersome process and significant manpower and time costs.

[0012] By using the cooperation of the third gear, the inner ring gear, and the sleeve, when adjusting the horizontal display direction of the display board, the sleeve drives the third gear to rotate, and the meshing of the third gear with the inner ring gear causes the inner ring gear to drive the fixed shell and the display board to rotate left and right. This solves the problem that when adjusting the display direction of the display board, the staff needs to move the display board to make adjustments, which is inconvenient during operation.

Detailed Implementation

[0018] 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.

[0019] In actual use, when adjusting the display direction or angle of a fixed-angle display board, it is often necessary to move the display board back to its original position or disassemble and reinstall it as a whole. The operation process is cumbersome and consumes a lot of manpower and time.

[0020] In view of this, the present invention provides an adjustable angle display board, which solves the problem that in actual use, when adjusting the display direction or angle of a fixed angle display board, it is often necessary to move the display board or disassemble and install it as a whole, which is cumbersome and consumes a lot of manpower and time.

[0021] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the art. The following mainly introduces the working principle and process.

[0022] Example 1: By Figure 1-4It is known that an adjustable angle display board includes a display panel 1. The outer walls of the display panel 1 are rotatably connected to a fixed frame 2 via sealed bearings. The bottom of the fixed frame 2 is fixedly connected to a fixed shell 3. The bottom of the fixed shell 3 is movably connected to a mounting frame 4. A worm gear 7 is fixedly connected to one end of the display panel 1 extending outside the fixed frame 2. A worm 6 is meshed with the outer wall of the worm gear 7. A protective shell 5 is rotatably connected to the outer wall of the worm 6 via sealed bearings. The outer wall of the protective shell 5 is fixedly connected to the outer wall of the fixed frame 2. One end of the protective shell 5 is fixedly connected to the outer wall of the fixed shell 3. A movable plate 19 is fixedly connected to the bottom of the mounting frame 4.

[0023] In the specific implementation process, it is worth noting that the front and back of the display board 1 are provided with positions for installing advertising boards, and the boards can also be directly glued to the display board 1 for display. The fixing frame 2 can fix them and provide protection. The protective shell 5 encloses the worm gear 6 and worm wheel 7 together to prevent the meshing between the two from being affected by external factors. At the same time, when the worm wheel 7 and worm gear 6 are meshing, they have a self-locking function. When the worm gear 6 rotates, it can drive the worm wheel 7 to rotate, but when the worm wheel 7 rotates, it cannot drive the worm gear 6 to rotate. Therefore, after adjusting the angle of the display board 1, with the cooperation of the worm wheel 7 and worm gear 6, the display board 1 will be stably fixed inside the fixing frame 2. The fixing shell 3 and the mounting bracket 4 support the display board 1 to ensure its stability during operation. In addition, the bottom four corners of the movable plate 19 are provided with rollers to facilitate the movement of the display board 1.

[0024] Furthermore, a first gear 8 is fixedly connected to the end of the worm gear 6 away from the worm wheel 7. A connecting rod 9 is provided below the first gear 8. One end of the connecting rod 9 is rotatably connected to the inner wall of the protective shell 5 through a bearing, and the other end passes through the side wall of the fixed shell 3 through a bearing. A second gear 14 is fixedly connected to the end of the connecting rod 9 extending into the interior of the fixed shell 3 and the side of the outer wall near the first gear 8. The second gear 14 near the first gear 8 is meshed with the side of the first gear 8. A sleeve 10 is meshed with the outer wall of another second gear 14. An insert rod 13 is inserted into the inner wall of the sleeve 10. The insert rod 13 passes through the fixed shell 3 through a sealed bearing and is fixedly connected to one end of the mounting frame 4 with a servo motor 11. A fixed frame 12 is fixedly connected to the outer wall of the servo motor 11. The outer wall of the fixed frame 12 is fixedly connected to the top of the inner wall of the mounting frame 4.

[0025] In the specific implementation process, it is worth noting that both the first gear 8 and the second gear 14 are bevel gears, and there are two second gears 14, located at both ends of the connecting rod 9. The top of the sleeve 10 is also a bevel gear, which can mesh with the second gear 14. When the servo motor 11 drives the insert rod 13 to rotate, it will cause the sleeve 10 to mesh with the second gear 14, thereby causing the connecting rod 9 to drive the second gear 14 at the other end to mesh with the first gear 8. The top of the first gear 8 is fixedly connected to the bottom of the worm gear 6, so it will drive the worm gear 6 to rotate, changing the angle of the display board 1. The model of the servo motor 11 is not limited, as long as it meets the actual use, and it is used through an external power supply and controller.

[0026] Furthermore, a limiting strip 20 is fixedly connected to the outer wall of the insertion rod 13, and the outer wall of the limiting strip 20 is inserted into the inner wall of the sleeve 10;

[0027] In the specific implementation process, it is worth noting that the limiting strip 20 is rectangular in shape, and the inner wall of the sleeve 10 is provided with a rectangular groove that is the same as the limiting strip 20. In this way, when the insertion rod 13 rotates, it can drive the sleeve 10 to rotate synchronously.

[0028] Example 2: From Figure 1-4 It can be seen that a third gear 15 is fixedly connected to the lower part of the outer wall of the sleeve 10, and an annular internal gear 16 is provided below the third gear 15. The bottom of the annular internal gear 16 is fixedly connected to the bottom of the inner wall of the fixed shell 3.

[0029] In the specific implementation process, it is worth noting that the annular internal gear 16 is an internal gear that can mesh with the third gear 15. When adjusting the horizontal display direction of the display board 1, the sleeve 10 is moved downward so that the third gear 15 on the lower part of the outer wall of the sleeve 10 meshes with the annular internal gear 16, thereby driving the fixed shell 3 and the display board 1 to rotate.

[0030] Furthermore, a limiting plate 17 is rotatably connected to the upper part of the outer wall of the sleeve 10 via a sealed bearing. An electric push rod 18 is fixedly connected to the top of the limiting plate 17, and the top of the electric push rod 18 is fixedly connected to the bottom of the fixed frame 2.

[0031] In the specific implementation process, it is worth noting that when pushing the sleeve 10 to the position, the electric push rod 18 is used to push the limit plate 17 and the sleeve 10 to rise and fall, so that the servo motor 11 can control the vertical and horizontal angles of the display board 1, which is convenient for the staff to use and saves costs. The limit plate 17 is rotatably connected to the sleeve 10 through a bearing to avoid the sleeve 10 being affected by the limit plate 17 when it rotates. The model of the electric push rod 18 is not limited, as long as it meets the actual use.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
