Description

Technical Field

[0001] The utility model relates to the technical field of LED splicing screens, and more specifically, to an LED splicing screen. Background Art

[0002] In the existing technology, the LED splicing screen needs to be fixed by a suction cup during installation and use. Usually, the operator needs to fit the suction cup to the back of the splicing screen, and then turn on the negative pressure switch to generate adsorption force to fix the splicing screen in the desired position. However, this mode of operation is somewhat cumbersome. First, manually fitting the suction cup to the back of the splicing screen may require precise manual operation, and the position of the suction cup may need to be adjusted to ensure the smooth adsorption of the splicing screen. Secondly, after turning on the negative pressure switch, you need to wait for a certain period of time so that the suction cup can be fully adsorbed, which may cause delays in the installation process. In addition, if the suction cup fails to fit correctly or the negative pressure is insufficient, the splicing screen may not be firmly fixed, affecting the use effect. Therefore, during the use of the existing equipment, due to the need for cumbersome adsorption operations, its convenience and efficiency are affected. Utility Model Content

[0028] See also Figure 1-5A LED splicing screen includes a fixed tube 1, which is installed on an external device. A fixing mechanism is arranged on the fixed tube 1. The fixing mechanism includes a sliding mechanism, an external tube 2, a suction cup 3, a one-way tube 4, a push rod 5, a round head 6, a one-way disk 7, an annular sleeve 8 and an adjustment mechanism. The sliding mechanism is cooperatively connected to the external tube 2 and the fixed tube 1. The suction cup 3 is installed on the external tube 2. The external tube 2 is connected to the external device. The one-way tube 4 is installed on the external tube 2. A sealing groove 9 is opened on the one-way tube 4. The one-way disk 7 fits in the sealing groove 9. The push rod 5 is installed on the one-way disk 7. A round head 6 is installed on the push rod 5. The back of the display screen is supported on the round head 6. A plurality of annular sleeves 8 are coaxially mounted on the one-way disk 7, a plurality of annular grooves 10 are provided on the one-way tube 4, the annular sleeves 8 abut against the annular grooves 10, an adjusting mechanism is cooperatively connected to the one-way tube 4, the adjusting mechanism comprises a threaded sleeve 11 and an intermediate sleeve 12, the threaded sleeve 11 is threadedly connected in the one-way tube 4, the intermediate sleeve 12 is installed in the threaded sleeve 11, a hexagonal rod 13 is coaxially mounted on the push rod 5, a hexagonal groove 14 is provided on the intermediate sleeve 12, the hexagonal rod 13 is slidably connected in the hexagonal groove 14, a rounded corner 15 is provided on the hexagonal rod 13, a spring 16 is sleeved on the hexagonal rod 13, and the two ends of the spring 16 abut against the intermediate sleeve 12 and the one-way disk 7 respectively.

[0029] In this embodiment, when multiple splicing screens are spliced, the multiple splicing screens need to be attached to the suction cup 3. Since the external pipe 2 is connected to the external suction device, negative pressure will be generated on the external pipe 2. Since the threaded sleeve 11 is threadedly connected in the one-way pipe 4, and the hexagonal rod 13 is stuck in the hexagonal groove 14, the rotation of the push rod 5 can drive the rotation of the threaded sleeve 11, so that the elastic force between the spring 16 and the one-way disk 7 can be changed, so that the elastic force of the single spring 16 is greater than the pressure of the negative pressure, so it can be guaranteed. The sealing effect between the one-way disk 7 and the sealing groove 9 is that when the splicing screen contacts the round head 6, the seal between the one-way disk 7 and the sealing groove 9 will be released, and then negative pressure will be generated between the suction cup 3 and the back of the splicing screen. Since the area of ​​the one-way disk 7 is much smaller than the area on the suction cup 3, the force of the negative pressure is the area multiplied by the pressure of the negative pressure. It is only necessary to ensure that the force on the suction cup 3 is greater than the force of the spring 16, and the force of the spring 16 is greater than the force on the one-way disk 7 to fix it. Therefore, it can be conveniently fixed, thereby completing the splicing process.

[0030] See also Figure 1 and Figure 2As an implementation of the sliding mechanism: the sliding mechanism includes a block 17, a screw 18 and a receiving plate 19, the receiving plate 19 is attached to the fixed tube 1, the external tube 2 is installed on the receiving plate 19, the screw 18 is installed on the block 17, the screw 18 is slidably connected to the receiving plate 19, a plurality of slide grooves 20 are opened on the side wall of the fixed tube 1, the block 17 is slidably connected in the slide groove 20, a handle 21 is threadedly provided on the screw 18, a compression spring 22 is provided on the handle 21, the compression spring 22 is sleeved on the screw 18, the compression spring 22 contacts the receiving plate 19, an insertion block 23 is provided on the receiving plate 19, and the insertion block 23 is slidably connected in the slide groove 20.

[0031] More specifically, when the position of the splicing screen needs to be adjusted, since the card block 17 is slidably connected in the slide groove 20, and the insertion block 23 is also slidably connected in the slide groove 20, the receiving plate 19 can be driven to move, thereby driving the movement of the splicing screen, and then by rotating the handle 21, the compression spring 22 is pressed against the receiving plate 19, thereby ensuring the fixation of the card block 17, and completing the movement of the splicing screen.

[0032] In summary, when the overall device is in use or running: when multiple splicing screens are spliced, the multiple splicing screens need to be attached to the suction cup 3. Since the external pipe 2 is connected to the external suction device, negative pressure will be generated on the external pipe 2. Since the threaded sleeve 11 is threadedly connected in the one-way tube 4, and the hexagonal rod 13 is stuck in the hexagonal groove 14, the rotation of the push rod 5 can drive the rotation of the threaded sleeve 11, so that the elastic force between the spring 16 and the one-way disk 7 can be changed, so that the elastic force of the single spring 16 is greater than the pressure of the negative pressure, so it can be To ensure the sealing effect between the one-way disk 7 and the sealing groove 9, when the splicing screen contacts the round head 6, the seal between the one-way disk 7 and the sealing groove 9 will be released, and then negative pressure will be generated between the suction cup 3 and the back of the splicing screen. Since the area of ​​the one-way disk 7 is much smaller than the area on the suction cup 3, the force of the negative pressure is the area multiplied by the pressure of the negative pressure. It only needs to ensure that the force on the suction cup 3 is greater than the force of the spring 16, and the force of the spring 16 is greater than the force on the one-way disk 7 to fix it. Therefore, it can be conveniently fixed, thereby completing the splicing process.

[0033] When the position of the splicing screen needs to be adjusted, since the card block 17 is slidably connected in the slide groove 20, and the insertion block 23 is also slidably connected in the slide groove 20, the receiving plate 19 can be driven to move, thereby driving the movement of the splicing screen, and then by rotating the handle 21, the compression spring 22 is pressed against the receiving plate 19, thereby ensuring the fixation of the card block 17, and completing the movement of the splicing screen.
