Detailed ways

The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

Example 1

A seamlessly splicable LED display cloud media, comprising a plurality of display modules, a reference plate connected to a plurality of the display modules, at least one positioning pin is provided on the display module, and the reference plate is provided with the same spacing. multiple or multiple sets of positioning holes; the display module includes a frame, a plurality of LED display units 2 arranged in the frame, an adapter board and a power supply; Corresponding limiting grooves 131, a limiting block 132 is arranged between the two corresponding limiting grooves 131; multiple groups of magnet blocks 121 are arranged on one side of the frame, and the LED display unit 2 is provided with There are a plurality of suction slots matching the magnet block 121 .

It should be noted that when designing the width of a display module or frame, the width is always designed to be a little smaller in order to leave a gap for thermal expansion and contraction. display screen, the width of each frame may be designed to be 49.5cm, and if the gap is not well controlled during splicing and installation, the width of the final spliced display screen may not be exactly 200cm, and at the same time every two The size of the gap between the frames may also vary, and the quality of the display surface of the entire display screen is not high. However, the present invention can effectively avoid the above-mentioned problems through the structure of positioning pins matched with the reference plate. Specifically, the reference plate can be set on the top or bottom of multiple frames, or can be set on the top and bottom at the same time, of course, it can also be set on The back of the frame, but setting it on the back of the frame will increase the thickness of the entire display to a certain extent. The number of positioning pins can generally be two, so as to ensure the accuracy of the position of the frame body and avoid its rotation. This embodiment takes the two positioning pins arranged on the top of the frame as an example. To match them, there are multiple sets of positioning holes on the reference plate, and each group includes two positioning holes. The intervals between them are the same, so that after multiple frames are installed, the gaps between adjacent frames are equivalent to ensure the quality of the entire display screen. At the same time, the total width of the display screen formed by splicing multiple frames is determined by the The width can be precisely controlled to avoid errors in the total width of the display.

When multiple frames are spliced, in order to ensure the flatness of the spliced display screen, it is necessary to control the consistency of the front and rear positions of the multiple frames. The present invention arranges corresponding limit grooves 131 on the connecting surfaces of adjacent frames, and uses limit blocks 132 to ensure that the limit grooves 131 of adjacent frames are precisely aligned and prevent accidental dislocation, thereby ensuring The flatness after splicing multiple frames is improved. Further, the limiting slots 131 have two symmetrical ones, so as to improve the limiting effect and position accuracy. Specifically, the limit slot 131 in this embodiment is one along the length (up and down) direction of the frame and runs through the entire frame, which is more convenient to process, while the limit block 132 does not need to be so long, and we can use it at the same time A plurality of evenly distributed limiting blocks 132 are arranged in one limiting groove 131 to ensure the limiting effect while saving materials. For the setting or installation of the limit block 132, we can first fix the limit block 132 in one of the corresponding two limit grooves 131 through the form of screw matching screw holes. The positioning block 132 is also snapped into another limiting slot 131.

Then, the installation structure of the LED display unit 2 adopts the mode of magnet attraction, that is, by arranging multiple groups of magnet blocks 121 on the front side of the frame body, and setting the attraction grooves for matching the magnet blocks 121 on the LED display unit 2 , when installing, it is only necessary to make a plurality of magnet blocks 121 respectively enter the corresponding suction grooves, of course, the material devices that can be attracted by the magnet blocks 121, such as iron blocks, etc., are arranged in the suction grooves, or The entire suction groove is the material that can be attracted by the magnet. The above-mentioned structure is not only convenient and efficient to install, but also convenient for later maintenance. For example, if one of the LED display units 2 is broken, it only needs to disassemble the single display unit for maintenance or replacement without disassembling the entire display screen, greatly Increased efficiency while reducing maintenance costs. The dismounting tool can be a tool such as a suction cup, as long as it can overcome the attractive force of the magnet block 121 .
