A push block 15 is fixedly connected to the middle of the stop block 14. A pin 16 is fixedly connected to the right side of the push block 15. A spring 17 is sleeved on the outside of the pin 16. A fixing block 18 is fixedly connected to the right side of the spring 17. The elasticity of the spring 17 and the force generated between the pin 16, the push block 15, and the fixing block 18 facilitate disassembly and assembly, and also better push the stop block 14 to lock it into the slot 13, effectively preventing... The display screen 3 slides down one side. An upper toothed ring 19 is fixedly connected to the bottom of the column 5. A through hole 22 is opened on the outside of the protective shell 7. A handle 9 is slidably connected inside the through hole 22. A lower toothed ring 20 is fixedly connected to the side of the handle 9 near the upper toothed ring 19. A spring 21 is fixedly connected to the bottom of the lower toothed ring 20. The connection between the column 5 and the upper toothed ring 19 is to better drive the main body to rotate. By pressing down the handle 9, the elasticity of the spring 21 is used to press down the lower toothed ring 20 to leave space, so that the upper toothed ring 19 and the column 5 can drive the main body to rotate, realizing free adjustment of the angle and the diversity of viewing angle changes.

[0025] Reference Figure 1 The top cover 2 is installed on the top of the display screen 3, and the display screen 3 is slidably connected to the front side of the card slot bracket 4. The top cover 2 serves both aesthetic and protective purposes, preventing dust from falling into the equipment and causing damage.

[0026] Reference Figure 3The stop 14 is slidably connected inside the slot bracket 4, and the pin 16 is slidably connected inside the frame 1. The stop 14 is set inside the slot bracket 4 to prevent the display screen 3 from slipping off one side and causing damage. The pin 16 is for easy assembly and disassembly of components and is more flexible.

[0027] Reference Figure 3 The pin 16 is slidably connected to the middle of the fixing block 18, and the spring 17 is fixedly connected to the right side of the push block 15. The pin 16, through the action of the fixing block 18, the spring 17, and the force of the spring 17 and the push block 15, can push the stop block 14 into the slot 13 to prevent the equipment from slipping and to make it more secure.

[0028] Reference Figure 4 The upper toothed ring 19 is rotatably connected inside the protective shell 7, and the second spring 21 is fixedly connected inside the protective shell 7. The protective shell 7 has a protective function to prevent the oxidation and corrosion damage of metallic components such as the toothed ring, thus providing greater safety.

[0029] Reference Figure 4 The upper toothed ring 19 engages with the top of the lower toothed ring 20. When the two are engaged, the main body can be made more stable and less likely to continue to rotate in other directions when adjusted to the required position.

[0030] Reference Figure 4 The upper toothed ring 19 is rotatably connected to the bottom of the limiting block 6. The limiting block 6 is installed to better fix the position and orientation of the equipment and also to protect the components below.

[0031] Reference Figure 4 The lower toothed ring 20 is slidably connected inside the protective shell 7 to prevent the toothed ring from being exposed to the outside and oxidized and corroded by external factors such as climate, thus avoiding damage and abnormal operation.

[0032] Working principle: First, multiple displays 3 are inserted into the slots 4 and 13 within the bracket 4 inside the frame 1. Then, electrical wires are inserted into the electrical socket 12 to provide power. After the displays 3 are installed, there is an opening because there is a slot 13 on one side of the frame 1. To prevent the displays 3 from slipping off one side due to the overall tilting, a disassembly device is designed at the opening connection. Pushing the pin 16 and the force of the spring 17 on the push block 15 pushes the stop block 14 into the slot 13. The stop block 14 can seal the opening and prevent... The display screen 3 slipped out of the slot and was damaged. The rear of the frame 1 is designed with a vent 10 and a cooling fan 11 to dissipate heat generated during use, ensuring normal operation. The column 5 is connected to the upper gear ring 19 because the handle 9 applies force to the lower gear ring 20. Utilizing the elasticity of the spring 21, the lower gear ring 20 can be pressed down, creating space. The column 5 can then freely adjust the angle and direction of the upper gear ring 19 as needed. The rotation angle is freely adjustable. After rotating to the desired angle, use handle 9 and spring 21 to apply upward force, engaging the lower toothed ring 20 with the upper toothed ring 19. Once locked, release handle 9. The base 8 is installed at the bottom of the entire device for greater stability. Finally, install the top cover 2 on top of the frame 1. The overall assembly is now complete. When not in use, first open the top cover 2. The elasticity of spring 21 presses down on handle 9, causing the lower toothed ring 20 to move downward to create space. This allows the column 5 and upper toothed ring 19 to rotate, restoring the entire device to its initial position. Then release handle 9, and use the reaction force of spring 21 to move the lower toothed ring 20 upward and engage it with the upper toothed ring 19. Then pull the pin 16, and use the reaction force of spring 17 and fixing block 18 to pull the stop block 14 out of the slot 13. After unplugging the wires on the electrical socket 12, slide the multiple displays 3 out of the slot bracket 4. The display 3 is expensive, and the splicing screen design makes it easy to store. The overall structure is more flexible and easier to carry and store, saving transportation costs and space.
