DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Reference Figure 1 and Figure 3 The utility model provides an embodiment: a signboard that is easy to fix, including a support rod 1, a fixed plate 3 is slidably connected to one side of the support rod 1, a support rod 4 is fixedly connected to one side of the fixed plate 3, a mounting plate 2 is fixedly connected to the top of the support rod 4, a groove 13 is provided inside the mounting plate 2, a motor 12 is fixedly connected inside the groove 13, a swing rod 17 is fixedly connected to the output end of the motor 12, both sides of the swing rod 17 are rotatably connected to a rotating shaft 20, the outsides of the two rotating shafts 20 are fixedly connected to miter rods 18, one end of the two miter rods 18 is rotatably connected to a moving plate 15, the through holes on both sides of the two moving plates 15 are connected to connecting columns 14, the top of the moving plate 15 is fixedly connected to a fixing column 19, the tops of the two fixing columns 19 are fixedly connected to a clamping plate 7, an indicator board 6 is arranged on the top of the mounting plate 2, and a lifting component is installed inside the support rod 1.

[0030] Specifically, the fixed plate 3 is adjusted up and down along the support rod 1 to adapt to different installation height and angle requirements. The support rod 4 supports and fixes the mounting plate 2. The motor 12 controls the rotation angle of the swing rod 17, thereby adjusting the opening and closing degree of the clamping plate 7 to achieve the clamping and release of the sign 6. When the swing rod 17 rotates, the rotating shaft 20 drives the miter rod 18 to swing, effectively converting the rotational movement of the swing rod 17 into horizontal movement of the movable plate 15. The clamping plate 7 is connected to the movable plate 15 through the fixed column 19. Therefore, when the movable plate 15 moves, the clamping plate 7 will also open and close accordingly, thereby ensuring that the sign 6 can be stably installed on the mounting plate 2.

[0031] Reference Figure 2 The lifting assembly includes a rack plate 8, the outside of the rack plate 8 is slidably connected to the inside of the support rod 1, one end of the rack plate 8 is fixedly connected to the sliding column 5, a limiting groove 11 is provided inside the support rod 1, the inside of the limiting groove 11 is rotatably connected to the worm gear 10, the outside of the support rod 1 is rotatably connected to the handle 21, and one side of the handle 21 is fixedly connected to the worm 9.

[0032] Specifically, since the rack plate 8 has teeth, it can mesh with the worm wheel 10 to achieve vertical up and down movement. When the rack plate 8 slides up and down inside the support rod 1, the sliding column 5 will also move accordingly. The limiting groove 11 opened inside the support rod 1 is used to ensure the stability of the lifting movement. At the same time, the limiting groove 11 also provides a sliding track for the rack plate 8, and also provides a rotation range for the worm wheel 10. When the handle 21 is rotated, the worm 9 will also rotate accordingly. Since the worm 9 and the worm wheel 10 are meshingly connected, the rotation of the worm 9 will drive the worm wheel 10 to rotate, so that the worm wheel 10 drives the rack plate 8 to perform lifting movement, and the worm 9 and the worm wheel 10 have a certain self-locking function, which ensures the stability and safety of the lifting movement.

[0033] Reference Figure 2 and 3 The two ends of the two connecting columns 14 are fixedly connected to the inside of the mounting plate 2, the outside of the swing rod 17 is rotatably connected to the inside of the groove 13, two slide grooves 23 are opened on the top of the mounting plate 2, the outside of the fixed column 19 is slidably connected to the inside of the slide groove 23, the outside of the support rod 1 is fixedly connected to the controller 22, the motor 12 is electrically connected to the controller 22, and the bottom of the support rod 1 is fixedly connected to the base 16.

[0034] Specifically, by fixing the connecting column 14 inside the mounting plate 2, a stable moving track can be provided for the moving plate 15. The design of the groove 13 provides a rotation space for the swing rod 17. The design of the slide groove 23 allows the fixed column 19D to drive the clamping plate 7 to move smoothly. The start, stop and rotation direction of the motor 12 can be conveniently controlled by the controller 22, thereby achieving precise control of the opening and closing degree of the clamping plate 7. The base 16 can ensure that the signboard can be firmly placed on the ground.

[0035] Reference Figure 2 The outside of the sliding column 5 is slidably connected to the inside of the support rod 1, and the other side of the fixed plate 3 is fixedly connected to the outside of the sliding column 5. The corresponding side of the outside of the worm wheel 10 is respectively meshed with the outside of the rack plate 8 and the worm 9, and the outside of the rack plate 8 is slidably connected to the inside of the limiting groove 11.

[0036] Specifically, the slide column 5 slides up and down inside the support rod 1, thereby driving the fixed plate 3 to perform lifting and lowering movements. The rotation of the worm wheel 10 drives the rack plate 8 to move up and down through the meshing action, thereby controlling the lifting and lowering of the slide column 5 and the fixed plate 3. When the handle 21 is rotated, the worm 9 will also rotate accordingly, thereby driving the worm wheel 10 meshing with it to rotate. The limit groove 11 is used to limit the movement trajectory of the worm wheel 10 and the rack plate 8, ensuring that they can perform stable lifting and lowering movements within a predetermined range, thereby preventing damage or instability caused by excessive lifting and lowering.

[0037] Working principle: First, the support rod 1 is fixed at the desired position through the base 16, and the motor 12 is started through the controller 22. When the motor 12 is working, it drives the swing rod 17 to swing. When the swing rod 17 swings, the miter rod 18 drives the moving plate 15 to move linearly under the guidance of the connecting column 14, so that the moving plate 15 drives the fixed column 19 to move, and further the fixed column 19 drives the clamping plate 7 to move accordingly, and then controls the clamping force of the clamping plate 7 on the sign 6, so as to realize the rapid replacement or fixing of the sign 6;

[0038] Secondly, by turning the handle 21 to drive the worm 9 to rotate, the rotation of the worm 9 will drive the worm wheel 10 meshing with it to rotate in the limit groove 11, and the rotation of the worm wheel 10 will further drive the rack plate 8 meshing with it to slide up and down inside the support rod 1. The sliding of the rack plate 8 will drive the sliding column 5 to move synchronously, and the movement of the sliding column 5 will drive the fixed plate 3 to move up and down, and then under the connection of the support rod 4, the fixed plate 3 drives the mounting plate 2 to move up and down, thereby realizing the height adjustment of the sign 6.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
