[0030] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0031] Refer to Figure 1 , Figure 2 and Figure 4 , an embodiment provided by the present utility model: a fixed vertical telescopic rod includes a fixed disk 8. The outer wall of the fixed disk 8 is fixedly connected with a support rod 9 for supporting the stability of the overall structure. The outer wall of the support rod 9 is rotatably connected with a reinforcing rod 10 to enhance the rigidity of the structure. One end of the reinforcing rod 10 is rotatably connected with a telescopic rod 6, and one end of the telescopic rod 6 is fixedly connected to the top of the fixed disk 8 to allow adjustment in the vertical direction. One end of the support rod 9 is fixedly connected with an inner bracket 11. An outer bracket 12 is arranged on the outer wall of the inner bracket 11, and the two are connected by a locking bolt 17 passing through to ensure stability. An arc-shaped groove 15 is formed inside the outer bracket 12 to allow the adjustment component to limit it. An adjustment component is arranged inside the inner bracket 11, including a tightening bolt 16. The threaded end of the tightening bolt 16 is connected inside the inner bracket 11, and the outer wall passes through the arc-shaped groove 15. The adjustment component is used to precisely adjust the position of the outer bracket 12. One side of the outer bracket 12 is fixedly connected with a frame 13, and a screen 14 is fixedly connected to the outer wall of the frame 13 to complete the final installation and positioning;
[0032] Specifically, during the installation of the device, the inner bracket 11 is connected to the outer bracket 12 through the support rod 9. The outer wall of the support rod 9 is connected to the telescopic rod 6 through the reinforcing rod 10 to enhance the stability of the overall structure. When it is necessary to adjust the inclination angle of the outer bracket 12, the bottom of the outer bracket 12 is adjusted around the anti-loosening bolt 17 as the rotation center. The fastening bolt 16 on the inner bracket 11 is tightly fitted with the outer bracket 12 by passing through the arc-shaped groove 15. Since the mounting base 1 is arc-shaped, the outer bracket 12 can achieve precise adjustment of the inclination angle with the anti-loosening bolt 17 as the center. After adjusting to the required angle, the fastening bolt 16 is tightened to ensure a firm connection between the outer bracket 12 and the inner bracket 11. Subsequently, the final locking is achieved by further rotating the anti-loosening bolt 17. After completing these steps, the screen 14 can be safely installed on the frame 13, and the frame 13 also supports the installation of other devices such as speakers, lights, and posters, improving the adaptability of the entire device.
[0033] Refer to Figure 3 , a mounting base 1 is fixedly connected to the top of the telescopic rod 6. A slack rope detector 5 is fixedly connected to the top of the mounting base 1, which is responsible for monitoring the tension change of the cable. A wire winding spring 7 is fixedly connected to the outer wall of the telescopic rod 6. One end of the wire winding spring 7 is fixedly connected to the bottom of the telescopic rod 6, which is used to maintain the tension of the cable. A motor 2 is fixedly connected to the top of the mounting base 1. A speed reducer 3 is arranged on the top of the mounting base 1. The input end of the speed reducer 3 is connected to the output end of the motor 2 to reduce the rotation speed of the motor 2. A wire winding disc 4 is rotatably connected to the top of the mounting base 1. The wire winding disc 4 is connected to the output end of the speed reducer 3. The release of the cable is controlled by the rotation of the wire winding disc 4 to adjust the length of the telescopic rod 6. The support rod 9 and the reinforcing rod 10 are arranged in a circular array and fixedly connected to the top of the fixed disc 8, providing stable support for the entire device;
[0034] Specifically, the mounting base 1 is firmly fixed above the stage. To adjust the height of the device, the output end of the motor 2 is decelerated through a precise speed reducer 3 and drives the rotation of the wire winding disc 4. As the wire winding disc 4 rotates, the cable is gradually released on its surface. After precise detection by the slack rope detector 5, the telescopic rod 6 can be gradually extended, driving the fixed disc 8 and the screen 14 to descend synchronously for height adjustment. When the tension of the cable changes and becomes loose, the slack rope detector 5 can quickly detect this change, thus preventing potential dangers caused by cable slack and ensuring stability and safety.
[0035] Working principle: When using this fixed vertical telescopic rod, first, the mounting base 1 is fixed above the stage. When the height needs to be adjusted, the output end of the motor 2 is decelerated by the speed reducer 3 and then drives the wire winding disc 4 to rotate. Subsequently, the cable is released through the wire winding disc 4 and descends through the detection of the loose rope detector 5, causing the telescopic rod 6 to extend in length, thereby driving the fixed disc 8 and the screen 14 to descend and adjust the height. When the cable becomes loose, it can be detected by the loose rope detector 5 to prevent danger. Subsequently, when installing the equipment, the inner bracket 11 and the outer bracket 12 are connected to the fixed disc 8 through the support rod 9. The outer wall of the support rod 9 is connected to the telescopic rod 6 through the reinforcing rod 10 to improve the connection strength. When the inclination angle of the outer bracket 12 needs to be adjusted, the bottom of the outer bracket 12 rotates around the anti-loosening bolt 17. The fastening bolt 16 on the inner bracket 11 is inserted into the arc-shaped groove 15. Since the mounting base 1 is arc-shaped, when the outer bracket 12 rotates around the anti-loosening bolt 17, the inclination angle of the outer bracket 12 is adjusted. Subsequently, the fastening bolt 16 is rotated to firmly fix the outer bracket 12 and the inner bracket 11. Finally, the anti-loosening bolt 17 is rotated for further locking. Subsequently, the screen 14 is installed on the frame 13. Different devices, such as speakers, lights, and posters, can be installed on the frame 13, achieving the effect of facilitating the installation of different devices and being able to adjust the hanging angle of the devices.
[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
