Technical Field

[0001] This utility model relates to the field of liquid crystal displays, specifically to a liquid crystal display splicing and fixing device. Background Technology

[0002] LCD screens use liquid crystal material as their basic component, filling the space between two parallel plates. By changing the arrangement of molecules within the liquid crystal material through voltage, light blocking and transmission are achieved, displaying images of varying depths and staggered shapes. Furthermore, by adding a three-color filter layer between the two plates, color images can be displayed. LCD video walls have a wide range of applications, primarily for exhibitions, shopping mall advertising, conferences, government affairs, and monitoring and command. Each video wall unit can be used individually as a monitor or combined to create a large screen. Depending on the application, a graphics processor enables the screen to be resized: single-screen multi-view display, single-screen single-view display, arbitrary combination display of video walls, image splicing, full-screen splicing, optional image border compensation or masking, support for digital signal roaming, scaling, stretching, cross-screen display, setting and running various display presets, and real-time processing of full HD signals.

[0003] However, there are still some problems when using LCD screens in a splicing process. The screens are not flat enough during assembly, resulting in poor viewing experience.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0021] The embodiments of this utility model will be described below based on its overall structure. Example

[0022] A liquid crystal display (LCD) splicing and fixing device, as shown in Figures 1-4, includes an LCD screen 1. A connecting base 104 is fixedly connected to the bottom of the LCD screen 1, and a coil is provided inside the connecting base 104. An iron core 105 is fixedly connected inside the connecting base 104. The iron core 105 is magnetically connected to a magnet 402. A pneumatic telescopic rod 401 is fixedly connected to one side of the magnet 402. The pneumatic telescopic rod 401 passes through the bottom of the mounting box 2 and is fixedly connected to a pneumatic integrated base 4. The pneumatic integrated base 4 is fixedly connected to a frame 3. Multiple sets of mounting boxes 2 are fixedly connected to the upper end of the frame 3. The frame 3 serves to splice and fix the mounting boxes 2.

[0023] After installing and fixing the frame 3, the pneumatic integrated base 4 is installed on the back of the frame 3. At this time, the corresponding number of mounting boxes 2 are taken out. The electronic integrated wire 5 is passed through the wire passage at the bottom of the mounting box 2 in advance. Then, the bottom opening of the mounting box 2 is aligned with the pneumatic telescopic rod 401 on the pneumatic integrated base 4. The mounting boxes 2 are installed one by one on the front of the frame 3.

[0024] Connect the power supply to the electronic integrated line 5 to power the LCD screen 1. Place the LCD screen 1 into the mounting box 2 along the guide block 103 on the back. Turn on the switch on the back of the LCD screen 1 to put the LCD screen 1 into standby mode. At this time, the coil inside the connecting base 104 is energized, which turns the iron core into an electromagnet 402. Place the magnet 402 on the connecting base 104 corresponding to the pneumatic telescopic rod 401. Under the action of the magnetic force, the LCD screen 1 is firmly fixed on the pneumatic telescopic rod 401.

[0025] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The side of the LCD screen 1 is fixedly connected to a frame 101, and the bottom of the frame 101 is fixedly connected to multiple sets of buffer springs 102, all of which are elastically connected to the mounting box 2.

[0026] When the pneumatic integrated base 4 is powered on, the pneumatic telescopic rod 401 can move back and forth, driving the pneumatic telescopic rod 401 to completely retract all the LCD screens 1 into the mounting box 2. Multiple sets of buffer springs 102 are installed at the bottom of the frame 101 to prevent the LCD screens 1 from directly contacting the mounting box 2, thus providing a buffering effect.

[0027] The working principle of this utility model is as follows: When installing, the installer should choose a suitable location to install and fix the frame 3, and then install the pneumatic integrated base 4 on the back of the frame 3. At this time, take out the corresponding number of mounting boxes 2, pass the electronic integrated wire 5 through the wire hole at the bottom of the mounting box 2 in advance, and then align the bottom opening of the mounting box 2 with the pneumatic telescopic rod 401 on the pneumatic integrated base 4. Install the mounting boxes 2 one by one on the front of the frame 3, and fix the screws to complete the installation.

[0028] At this point, the installer can install part 1 of the LCD screen. First, take out one LCD screen 1 and check if the screen is damaged. Then, install the frame 101 on the side of the LCD screen 1. The frame 101 serves to protect the LCD screen 1. Then, connect the electronic integrated wire 5 that passes through the bottom of the mounting box 2 to the integrated wire interface 106 on the back of the LCD screen 1. Repeat the operation to assemble all the LCD screens 1. Turn on the power of the electronic integrated wire 5 to power up the LCD screen 1. Place the LCD screen 1 into the mounting box 2 along the guide block 103 on the back. Turn on the switch on the back of the LCD screen 1 to put the LCD screen 1 into standby mode. At this time, the coil inside the connecting base 104 is energized, which turns the iron core into an electromagnet 402. Place the magnet 402 on the connecting base 104 corresponding to the pneumatic telescopic rod 401. Under the action of the magnetic force, the LCD screen 1 is firmly fixed on the pneumatic telescopic rod 401. Similarly, install all the LCD screens 1 in sequence.

[0029] The installer connects the power supply to the pneumatic integrated base 4, allowing the pneumatic telescopic rod 401 to move back and forth. Driving the pneumatic telescopic rod 401 completely retracts all the LCD screens 1 into the mounting box 2. Multiple sets of buffer springs 102 are installed at the bottom of the frame 101, preventing the LCD screens 1 from directly contacting the mounting box 2, thus providing a buffering effect. External signals are input via the electronic integrated line 5, allowing the installer to monitor the operating status of the LCD screens 1. If a display problem is found in any LCD screen 1, it needs to be disassembled and replaced. The pneumatic telescopic base is activated, driving the pneumatic telescopic rod 401 at the bottom of the corresponding LCD screen 1 to push the LCD screen 1 out. The switch behind the LCD screen 1 is then turned off, demagnetizing the iron core and reducing the attraction of the magnet 402 on the pneumatic telescopic rod 401 to the iron core. The electronic integrated line 5 is then disconnected, allowing the LCD screen 1 to be removed for replacement.
