[0002] Advertising signs are a tool for displaying promotional materials. They have advantages such as simplicity, clarity, and originality, and can play a role in displaying products, conveying information, and promoting sales. Advertising signs are divided into two types according to actual needs: those placed on the ground and those installed at high places.

[0003] For billboards placed on the ground, the advertising surface is mostly displayed in only one direction. When it is necessary to adjust the display angle, the entire billboard needs to be lifted and rotated. In order to ensure the stability of the billboard, the billboard is usually heavy, making it inconvenient to lift and place, and inconvenient for users. Therefore, to address the above problems, an advertising signboard that is easy to adjust the angle is proposed. Utility Model Content

A through groove 54 communicating with the positioning groove is opened on one side of the outer wall of the base 1. A transmission block 55 is fixedly connected to one side of the outer wall of the internal gear 51. One end of the transmission block 55 extends out of the through groove 54. During operation, a limiter is provided between the positioning rod 3 and the transmission rod 2 to ensure that the positioning rod 3 can rotate synchronously with the rotation of the transmission rod 2. The adjustment mechanism 5 and the transmission rod 2 are connected to the positioning rod 3. The setting 2 allows for easy adjustment of the angle of the sign body 4, eliminating the need for lifting and lowering to adjust the angle, reducing manpower consumption and improving adjustment efficiency. Specifically, when it is necessary to adjust the facing angle of the sign body 4, the foot can step on the transmission block 55 to drive the internal gear 51 to descend, causing the internal gear 51 to disengage from the first gear 53, releasing the rotation limit on the transmission rod 2, and thus pushing the sign body 4 to rotate to adjust its facing angle. After adjustment, the foot can be released from pressing the transmission block 55, and under the pressure of the spring 52, the internal gear 51 will reset and limit the rotation of the first gear 53, automatically completing the rotation limit of the adjusted sign body 4.

[0027] Furthermore, such as Figure 1 and Figure 3 As shown, a support plate 6 is fixedly connected to the bottom of the sign body 4. A support groove is provided at the bottom of the support plate 6, and a roller is rotatably connected to the inner side wall of the support groove via a pivot. During operation, the support plate 6 and the rollers provide auxiliary support for the sign body 4 during rotation and adjustment.

A first lead screw 7 is threaded into the first threaded hole. One end of the first lead screw 7 extends out of the first threaded hole and is inserted into a slot on one side of the positioning rod 3. The other end of the first lead screw 7 extends out of the first threaded hole. During operation, the arrangement of the first lead screw 7 and the slot allows the sign body 4 and the base 1 to be separated and disassembled, facilitating the transfer of the advertising sign during transportation and making it easy to replace the sign body 4. That is, by rotating the first lead screw 7, the movement of one end of it in the slot is controlled to position the positioning rod 3.

[0029] Furthermore, such as Figure 1 and Figure 3 As shown, a pressing ring 8 is slidably connected to the outer wall of the base 1, and the transmission block 55 is fixedly connected to the pressing ring 8 at one end located on the outside.

During operation, the knob 9 facilitates the rotation of the first lead screw 7 by turning the knob 9.

[0031] Furthermore, such as Figure 1 and Figure 2 As shown, a limiting rod 10 is fixedly connected to the top of the base 1, and a counterweight 11 is slidably connected to the outer wall of the limiting rod 10. A second threaded hole is opened at the top of the limiting rod 10, and a second lead screw is threaded into the second threaded hole. The top end of the second lead screw extends out of the second threaded hole and is fixedly connected to a pressing block. During operation, the counterweight 11, the limiting rod 10, and the second lead screw can be used to strengthen the gravity of the base 1, thereby reducing the possibility of the sign body 4 tipping over. The number of counterweights 11 sleeved on the outside of the limiting rod 10 can be controlled by rotating the pressing block and moving the second lead screw.

[0032] Furthermore, such as Figure 1 and Figure 2 As shown, the bottom of the base 1 is provided with anti-slip protrusions, and the inner wall of the pressing ring 8 is provided with a sealing gasket. During operation, the anti-slip protrusions on the bottom of the base 1 increase friction, and the sealing gasket on the inner wall of the pressing ring 8 improves sealing.

[0033] Working principle: When it is necessary to adjust the facing angle of the sign body 4, the foot can step on the transmission block 55 to drive the internal gear 51 to descend, so that the internal gear 51 disengages from the first gear 53, releasing the rotation limit on the transmission rod 2, and thus pushing the sign body 4 to rotate to adjust its facing angle. After the adjustment is completed, the foot can be released from pressing the transmission block 55. Under the pressure of the spring 52, the internal gear 51 resets and limits the rotation of the first gear 53, automatically completing the rotation limit of the adjusted sign body 4.
