[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] Example 1 like Figures 1 to 6 As shown, an LED signboard according to the first aspect of this utility model includes a base plate 1, a signboard body 5, and pulleys 6 at the four corners of the bottom surface of the base plate 1. The feature is that a control box 4 is fixedly connected to the top surface of the base plate 1. The control box 4 is provided with a lifting assembly 3 that causes the signboard body 5 to rise and fall for storage by rotation. The lifting assembly 3 includes two mounting shells 301. The bottom surfaces of the two mounting shells 301 are fixedly connected to the top surface of the control box 4. Each mounting shell 301 has a groove 303 on one side. Each groove 303 communicates with the interior of the corresponding mounting shell 301. The control box 4 is provided with a positioning assembly 2 that moves downward to contact the ground when the signboard body 5 is raised.

[0023] The technical effects achieved by the above embodiments are as follows: the lifting component 3 on the control box 4 realizes the lifting and storage of the light sign stand body 5, and at the same time, the positioning component 2 automatically contacts the ground when the stand body 5 is raised to ensure the stability of use, and detaches from the ground when the stand body 5 is lowered for storage, and cooperates with the pulley 6 to realize the convenient movement of the device, thereby effectively improving the overall convenience of use of the device.

[0024] Example 2 like Figure 3 and Figure 6 As shown, an LED signboard includes all the contents of Embodiment 1. In addition, the lifting assembly 3 also includes a transmission rod 308. One end of the transmission rod 308 is connected to one side of the inner wall of the control box 4 via a bearing, and the other end of the transmission rod 308 extends to the surface of the control box 4 and is fixedly connected to a handle. The lifting assembly 3 also includes two driving bevel gears 306, the inner walls of which are fixedly connected to the rod wall of the transmission rod 308. A driven bevel gear 307 is meshed with one side of each driving bevel gear 306, and a lead screw is fixedly connected to the top of each driven bevel gear 307. 302, the top end of each lead screw 302 extends into the interior of the corresponding mounting housing 301, and the top end of each lead screw 302 is connected to the top surface of the inner wall of the corresponding mounting housing 301 through a bearing. The lifting assembly 3 also includes two moving blocks 304, the inner wall of each moving block 304 is threadedly connected to the rod wall of the corresponding lead screw 302, and one side of each moving block 304 extends to the surface of the corresponding mounting housing 301 through a corresponding sliding groove 303. The opposite sides of the two moving blocks 304 are fixedly connected to a bearing plate 305, and the top surface of the bearing plate 305 is fixedly connected to the bottom surface of the stand body 5.

[0025] The technical effects achieved by the above embodiments are as follows: When the user rotates the handle fixed at the end of the transmission rod 308, the transmission rod 308 rotates and drives the active bevel gear 306 fixedly connected to its rod wall. This gear meshes with the driven bevel gear 307, driving the lead screw 302 to rotate within the mounting housing 301. The threaded connection of the lead screw 302 causes the moving block 304 to slide up and down along the slide groove 303, thereby driving the support plate 305 to rise and fall, realizing convenient storage or unfolding of the stand body 5. This gear transmission mechanism not only simplifies the operation process, but also avoids external force interference through smooth lifting and lowering movements. At the same time, combined with the pulley 6 at the bottom of the base plate 1, it facilitates the movement of the device in the stored state. In addition, the positioning component 2 inside the control box 4 automatically moves down to contact the ground when the stand body 5 is raised, ensuring stability during use. When it is lowered, it detaches from the ground and works with the pulley 6, significantly improving the portability and practicality of the device. The overall design is compact and efficient.

[0026] Example 3 like Figure 3 , Figure 4 and Figure 6As shown, an LED signboard includes all the contents of Embodiment 2. Furthermore, the positioning component 2 includes a bidirectional threaded section 203 formed on the wall of the transmission rod 308. Two control blocks 204 are threadedly connected to the wall of the bidirectional threaded section 203. The positioning component 2 also includes an auxiliary groove 208 and two vertical grooves 206. The two vertical grooves 206 are respectively formed on opposite sides of the inner wall of the control box 4. The auxiliary groove 208 is formed on the bottom surface of the base plate 1 and communicates with the interior of the control box 4. The positioning component 2 also includes a first control rod 201 and a second control rod 202. The top ends of the first control lever 201 and the second control lever 205 are respectively hinged to the bottom of the corresponding control block 204. The bottom ends of the first control lever 201 and the second control lever 205 extend to the bottom surface of the base plate 1 through the auxiliary groove 208 and are fixedly connected to the positioning block 202. The positioning assembly 2 also includes a connecting rod 207. The rod wall of the connecting rod 207 is connected to the inner wall of the center of the first control lever 201 and the second control lever 205 through bearings. The two ends of the connecting rod 207 are respectively slidably connected to the inner wall of the corresponding vertical groove 206.

[0027] The technical effects achieved by the above embodiments are as follows: When the user rotates the handle at the end of the transmission rod 308, the rotation of the transmission rod 308 drives the bidirectional threaded section 203 on its rod wall, causing the two threaded control blocks 204 to move towards or in opposite directions; the control blocks 204, through the hinged first control rod 201 and second control rod 205, push the positioning block 202 to move downward through the auxiliary groove 208 to contact the ground, providing stable support when the stand body 5 is raised, effectively preventing tipping and displacement; at the same time, the connecting rod 207 slides in the vertical groove 206 to ensure smooth movement without deviation; when the stand body 5 is lowered and stored by the lifting assembly 3, the reverse movement of the bidirectional threaded section 203 drives the control block 204 to move upward, causing the positioning block 202 to lift off the ground and cooperate with the pulley 6 at the bottom of the base plate 1 to achieve barrier-free movement of the device, significantly improving portability and operating efficiency, and avoiding the need for multiple people to carry it.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
