[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] Reference Figure 1-5 An easy-to-install LED display screen includes a fixed base 1 and two fixed blocks 2. The fixed base 1 has an internal mounting cavity with a pushing device inside. Multiple limiting holes 13 are equally spaced on both sides of the fixed base 1, and each limiting hole 13 communicates with the mounting cavity. Each fixed block 2 has a mounting groove 10 at its bottom end, and each mounting groove 10 has a limiting device. The output ends of two limiting devices are respectively inserted into the corresponding limiting holes 13. A connecting block 3 is fixedly connected to one side of each fixed block 2, and a display screen 4 is fixedly connected to one side of the two connecting blocks 3. A rotating block 14 is fixedly installed on the side of the fixed base 1 away from the connecting block 3. A drive shaft 15 is fixedly connected to both ends of the rotating block 14. A base 17 is rotatably installed on the outer wall of each drive shaft 15. The base 17 is used to fix the entire device to a wall or other supporting structure, providing a stable support foundation for the device and ensuring that the display screen 4 will not shake or tip over during installation and use, thus ensuring the safety and stability of the device.

[0023] Each drive shaft 15 is fixedly installed with an anti-slip nut 16 at one end. When the display screen 4 is adjusted to a suitable angle, tightening the anti-slip nut 16 can use its friction to fix the drive shaft 15, preventing the drive shaft 15 from rotating during use, thereby avoiding the angle of the display screen 4 from shifting and ensuring that the display screen 4 can work stably at the set angle.

[0024] The actuating device includes a fixed shaft 8, which is rotatably mounted on the inner wall of the mounting cavity. Handles 5 are fixedly connected to both ends of the fixed shaft 8. Protrusions 9 are fixedly mounted on the outer wall of the fixed shaft 8. Two pointers 7 are mounted on both ends of the fixed shaft 8, which rotatably penetrate the inner wall of the mounting cavity and extend outward. When the protrusions 9 rotate with the fixed shaft 8, they can actuate the fixed block 2, causing the fixed rod 12 to separate from the limiting hole 13 and quickly release the fixed relationship.

[0025] Two pointer blocks 6 are symmetrically fixed at both ends of the fixed base 1, and the pointer 7 points to the corresponding pointer block 6. The pointer 7 rotates with the fixed shaft 8. By pointing to the corresponding pointer block 6, the user can intuitively judge the rotation state of the protrusion 9 and ensure the accuracy of the jacking operation.

[0026] Each limiting device includes a spring 11, which is fixedly connected in the mounting groove 10. One end of the spring 11 is fixedly connected to a fixing rod 12, which is slidably connected in the mounting groove 10. One end of the fixing rod 12 is inserted into the corresponding limiting hole 13. In its natural state, the spring 11 pushes the fixing rod 12 out of the mounting groove 10 and into the limiting hole 13, thereby achieving automatic fixing of the fixing block 2 and the fixing base 1 without the need for additional tools, which simplifies the installation steps.

[0027] One end of each fixing rod 12 is rounded.

[0028] When using this utility model, the bottom ends of the two fixing blocks 2 connected to the display screen 4 via the connecting block 3 are aligned with the two ends of the fixing base 1. Then, the two fixing blocks 2 are moved. At this time, the fixing rod 12 in the mounting groove 10 will first contact the edge of the fixing base 1. Because one end of the fixing rod 12 is rounded, it will compress the spring 11 and retract into the mounting groove 10 after being squeezed. When the fixing block 2 is moved to the appropriate position and the mounting groove 10 is aligned with the corresponding limiting holes 13 on both sides of the fixing base 1, the elastic force of the spring 11 will push the fixing rod 12 out of the mounting groove 10, so that one end of it is inserted into the corresponding limiting hole 13, thereby fixing the fixing block 2 and the fixing base 1 respectively, and the display screen 4 is also fixed.

[0029] When it is necessary to disassemble or adjust the position of the display screen 4, rotate the handles 5 at both ends of the fixed shaft 8 to drive the fixed shaft 8 and the protrusions 9 on the outer wall to rotate in the mounting cavity. As the protrusions 9 rotate, when the protrusions 9 contact the bottom of the fixed block 2, they will push the fixed block 2 to move upward, so that the fixed rod 12 is squeezed by the edge of the limiting hole 13, thereby compressing the spring 11 and retracting the mounting groove 10, releasing the fixed relationship between the fixed block 2 and the fixed base 1, making it easy to remove the fixed block 2 or adjust it to other positions.

[0030] During the rotation of the fixed shaft 8, the pointers 7 at both ends of the fixed shaft 8 will rotate together with it. The pointers 7 point to the pointer blocks 6 symmetrically installed at both ends of the fixed base 1. By observing the position of the pointer blocks 6 pointed to by the pointers 7, the rotation state of the protrusion 9 can be determined, ensuring that the jacking device can accurately control the jacking of the fixed block 2 during operation.

[0031] Multiple limiting holes 13 equidistantly opened on both sides of the fixed base 1 provide multiple installation position options for the fixed block 2. According to the actual installation requirements, the fixed block 2 can be adjusted to a suitable position so that the fixed rod 12 can be inserted into the corresponding limiting hole 13, thereby realizing flexible adjustment of the installation position of the display screen 4.

[0032] The base 17 is fixed to a wall or other supporting structure, and the fixed base 1 is rotatably mounted on the base 17 via a drive shaft 15 connected to a rotating block 14. When it is necessary to adjust the angle of the display screen 4, loosen the anti-slip nut 16 at one end of the drive shaft 15, push the fixed base 1 to drive the display screen 4 to rotate around the drive shaft 15 until a suitable angle is reached. Then tighten the anti-slip nut 16, using its friction to fix the drive shaft 15, preventing the display screen 4 from shifting at an angle during use, and achieving stable placement of the display screen 4 at multiple angles.

[0033] 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.
