[0021] Please refer to Figures 1-2 The utility model provides a kind of small-pitch LED display screen module, including display screen module 1 and quick assembly mechanism 2, and the back edge of display screen module 1 is provided with quick assembly mechanism 2.

[0022] Please refer to Figures 3-5 The utility model provides a kind of small-pitch LED display screen module, and quick assembly mechanism 2 includes connecting rail 21, limiting portion 22, assembling sleeve 23, plug-in cavity 24, torsional spring rotating shaft 25, limiting frame 26, clamping portion 27 and clamping groove 28, and connecting rail 21 is screw-mounted on the back edge of display screen module 1, limiting portion 22 is integrally arranged at the end of connecting rail 21, plug-in cavity 24 is arranged through left and right in assembling sleeve 23, assembling sleeve 23 can be sleeved on the surface of two mutually adhered connecting rails 21 by plug-in cavity 24, so as to fix two connecting rails 21 together, torsional spring rotating shaft 25 is installed on the end surface of assembling sleeve 23, limiting frame 26 is installed on the surface of torsional spring rotating shaft 25, limiting frame 26 is elastically rotationally connected with assembling sleeve 23 by torsional spring rotating shaft 25, clamping portion 27 is integrally arranged at the end of limiting frame 26, clamping groove 28 is arranged at the head end of connecting rail 21, and limiting frame 26 can be clamped and fixed with the inner side of clamping groove 28 by clamping portion 27, so as to limit assembling sleeve 23 from moving away.

[0023] Further illustrate that four connecting rails 21 are arranged, and four connecting rails 21 are arranged at four side edge positions on the back of display screen module 1, allow display screen module 1 to be horizontally spliced and longitudinally spliced, and have strong installation adaptability.

[0024] Further illustrate, the length of the connecting rail 21 is not less than 80% of the length of the side of the display screen module 1, which ensures the stability of the splicing between the display screen modules 1.

[0025] Further illustrate, the connecting rail 21 is L-shaped, and the plug cavity 24 is T-shaped, which ensures the mounting firmness of the plug cavity 24 and the connecting rail 21.

[0026] Further illustrate, the turning angle of the limiting frame 26 around the torsion spring shaft 25 is not less than 120 degrees, which ensures that the assembly sleeve 23 can be normally sleeved with the connecting rail 21 when the limiting frame 26 is in the unfolded state.

[0027] Further illustrate, the depth of the clamping groove 28 is not less than 5 mm, and the size of the clamping part 27 and the clamping groove 28 is matched, which ensures that the clamping part 27 and the clamping groove 28 have sufficient connection length and are not easy to accidentally fall off.

[0028] The working principle is as follows:

[0029] When the display screen modules 1 are assembled, first, the two display screen modules 1 are aligned and spliced together, so that the two adjacent connecting rails 21 are in the state of abutment, then the assembly sleeve 23 is sleeved on the surface of the two connecting rails 21 through the plug cavity 24, and the limiting frame 26 should be unfolded outward during the installation of the assembly sleeve 23, so as to avoid affecting the sleeving action of the assembly sleeve 23 and the connecting rail 21, when the assembly sleeve 23 is blocked by the limiting part 22, the clamping part 27 will correspond to the position of the clamping groove 28, at this time, the limiting frame 26 is driven to turn and close by the elastic force of the torsion spring shaft 25, so that the clamping part 27 is clamped into the inside of the clamping groove 28, and the movement of the assembly sleeve 23 is limited from disengaging, so as to fix the two connecting rails 21 together, that is, the abutment installation between the display screen modules 1 is realized, without the help of external tools, the installation is fast.

[0030] When the abutment fixation between the display screen modules 1 needs to be released, first, the limiting frame 26 is unfolded, so that the clamping part 27 is separated from the inside of the clamping groove 28, then the assembly sleeve 23 is slid outward to disengage from the surface of the connecting rail 21, so as to release the abutment fixation between the display screen modules 1 and complete the disassembly, without the help of external tools, the disassembly is fast.

[0031] The above is only a preferred example of the present application, and is not used to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, the technical solutions recorded in the foregoing embodiments can still be modified by those skilled in the art, or some technical features can be replaced equivalently.
