Description

Technical Field

[0001] The present invention relates to the field of display technology, and in particular to a built-in hidden splicing display screen. Background Art

[0002] With the rapid development of information technology, display screens are increasingly widely used in various fields, such as commercial displays, monitoring centers, meeting rooms and other scenarios. For these application scenarios, a relatively large display area is often required to meet people's needs for information display. A large-screen display system composed of multiple spliced display screens has emerged. It can provide a larger display area while ensuring a high resolution and clarity, enabling viewers to obtain information more clearly.

[0003] In terms of splicing efficiency, the splicing process of traditional spliced display screens is relatively complex, requiring a large amount of time and labor. This not only increases the installation cost, but also fails to meet the requirements for quick installation and disassembly in some occasions with strict installation time requirements, such as the construction of display screens for temporary activities. In addition, the complex splicing process is prone to splicing errors, affecting the display effect after splicing. When it is necessary to detect the power components at the back of the display screen, the entire display screen needs to be disassembled or complex operations need to be carried out from the back of the display screen. This not only increases the installation difficulty and time, but also easily damages other components of the display screen during the operation. At the same time, when the power components fail and need to be repaired or replaced, the problem of inconvenient operation is also faced, affecting the normal use and maintenance efficiency of the display screen.

[0004] In order to overcome the deficiencies of the prior art and meet the higher requirements of the market for spliced display screens in terms of structure, splicing efficiency, and installation of power components, the present invention provides a built-in hidden spliced display screen that can quickly splice multiple display screens. Its splicing components are located in a rectangular frame at the back of the display screen, and the front side of the display screen can be opened for installing the power components required for the display screen, effectively solving the above problems.

Flat belts are wound between the two belt pulleys on the same side.On the left side of the installation frame 1, there is a horizontal splicing component 10 for horizontal splicing and fixation. The horizontal splicing component 10 includes a horizontal clamping block 102, a square block 103, and a sliding shaft 105. Horizontally through slots 101 are symmetrically opened on the upper and lower sides of the left side wall of the installation frame 1. The horizontal clamping block 102 is slidably arranged in the horizontal through slots 101 of the installation frame 1.

Horizontally clamping grooves 106 are symmetrically opened on the upper and lower sides of the right side wall of the installation frame 1. The horizontal clamping block 102 is matched with the horizontal clamping grooves 106 of the installation frame 1.,

[0027] As Figure 1 and Figure 5 shown, it further includes a limiting component 11. The limiting component 11 includes a sliding block 112, a second screw rod 113, and a pressing plate 114. A sliding groove 111 is opened at the bottom of the limiting rod 84. The sliding block 112 is slidably arranged in the sliding groove 111 of the limiting rod 84. An internal threaded hole is opened on the sliding block 112. The second screw rod 113 is screwed into the internal threaded hole of the sliding block 112. The front end of the second screw rod 113 is rotatably provided with the pressing plate 114.,

[0028] As Figure 5 shown, it further includes a U-shaped frame 13 and a trapezoidal clamping block 14. U-shaped frames 13 are symmetrically arranged on the front side wall of the left longitudinal beam 7 up and down. Trapezoidal clamping blocks 14 are symmetrically arranged inside the U-shaped frames 13 up and down. Trapezoidal clamping grooves 15 are symmetrically opened at one end of the wire sliding rod 64 far from the first rotating shaft 61. Bevels are symmetrically opened at the positions of the wire sliding rod 64 where the trapezoidal clamping grooves 15 are opened. The trapezoidal clamping grooves 15 are clamped and matched with the trapezoidal clamping blocks 14 inside the U-shaped frames 13. The bevels of the wire sliding rod 64 are beneficial for passing through the trapezoidal clamping blocks 14.,

[0029] When the display screen needs to be assembled, the staff first fix the longitudinal beam 7 in the installation frame 1 to the wall or the mounting rack of the large screen to be assembled. It is fixed by screws passing through the installation round holes of the longitudinal beam 7. Then, the installation plate 4 is rotated open around the first rotating shaft 61, and the liquid crystal display screen 5 rotates open accordingly. The rectangular block 65 slides correspondingly on the wire sliding rod 64. At this time, the staff passes the circuit of the liquid crystal display screen 5 through the strip-shaped hole of the installation plate 4, and then fixes the corresponding control components and power components on the fixing plate 83. It is installed by matching the bolts with the installation holes 85 of the fixing plate 83. The position is adjusted by sliding the sliding block 112 back and forth. The pressing plate 114 is pressed against the control components and power components to hold and fix them. Then, the second screw rod 113 is rotated. As a result, the lower part of the pressing plate 114 moves backward, and thus the whole pressing plate 114 can protect and fix the control components and power components. The wire harness connected to the liquid crystal display screen 5 is fixed on the wire harness tube 12. The fixing plate 83 is moved up and down to adjust to a suitable position. By rotating the rotating rod 97, the rotating rod 97 drives the first screw rod 96 to rotate through the pulley and the flat belt. The first screw rod 96 drives the sliding rod 94 and the vertical clamping block 95 to move downward. As a result, the hidden vertical clamping block 95 inside is exposed and can be assembled and fixed in cooperation with the vertical clamping groove 91 on the upper part of another installation frame 1. The downward movement of the sliding rod 94 drives the sliding shaft 105 to move downward. The sliding shaft 105 presses the one-way inclined groove 104 of the square block 103. As a result, the square block 103 drives the hidden horizontal clamping block 102 inside to move leftward and be exposed, and can be assembled and fixed in cooperation with the horizontal clamping groove 106 on the right side of another installation frame 1. The installation plate 4 is rotated back to its original position around the rotating shaft 3. The wire sliding rod 64 is clamped into the U-shaped frame 13. The trapezoidal clamping groove 15 of the wire sliding rod 64 is clamped and fixed with the trapezoidal clamping block 14 of the U-shaped frame 13. The structure of this device is simple, and it can be assembled and spliced quickly, which is convenient for opening and checking the electronic display screen with problems after splicing, and is convenient for troubleshooting and replacement.
