The terms "installed", "one end", "the other end" and similar expressions used herein are for illustrative purposes only.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art. The terms used in the specification herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0025] Please refer to Figures 1 to 6The embodiment of the present invention provides an assembled display screen, which includes at least two display modules 1 and a connecting component 2 arranged between two adjacent display modules 1. The connecting component 2 can be arranged on each frame on the back of the display module 1. The connecting component 2 is used to assemble and connect two adjacent display modules 1. A plurality of display modules 1 are spliced ​​together to form a complete display screen. The connecting component 2 includes a connecting pin 21, a connecting sheet 22 and a first elastic element 23. The first elastic element 23 can be a spring. The first elastic element 23 is connected to the connecting sheet 22 along a first direction, and is used to limit the movement of the connecting sheet 22 along the first direction, that is, the first elastic element 23 and the connecting sheet 22 are in the same plane. Two adjacent display modules 1 can be spliced ​​up and down, and the connecting piece 22 is detachably arranged on the frame of one of the two adjacent display modules 1 (such as the display module 1 located above), and the connecting pin 21 is correspondingly arranged on the frame of the other of the two adjacent display modules 1 (such as the display module 1 located below), and the connecting pin 21 is movably connected with the display module 1. The connecting pin 21 can be a cylindrical structure, and the frames of the two adjacent display modules 1 are provided with a through hole (not shown in the figure), the position of the through hole corresponds to the position of the connecting pin 21, and the shape of the through hole is adapted to the shape of the connecting pin 21, and the connecting pin 21 can pass through the two through holes. A first connecting hole 22a is provided on the connecting piece 22, and the shape of the first connecting hole 22a is adapted to the shape of the connecting pin 21, and the first connecting hole 22a can be a circular hole. The connecting pin 21 is provided with a connecting groove 21a along its axial direction, and the connecting groove 21a is set inwardly, and the radial dimension of the connecting groove 21a is smaller than the radial dimension of the connecting pin 21. In the connection state, first adjust the positions of the two adjacent display modules 1 so that the positions of the two through holes correspond; move the connecting piece 22 along the first direction (such as horizontal direction) so that the position of the first connecting hole 22a corresponds to the positions of the two through holes, and the first elastic element 23 is in a compressed state at this time; the connecting pin 21 passes through the frames of the two adjacent display modules 1 and the first connecting hole 22a of the connecting piece 22 along the second direction (such as vertical direction), and when the connecting groove 21a falls into the first connecting hole 22a, the compression state of the first elastic element 23 is released, so that the first elastic element 23 rebounds in the opposite direction of the first direction to lock. The difference between the radial dimension of the connecting groove 21a and the radial dimension of the connecting pin 21 is used to limit the movement of the connecting pin 21 in the second direction.

[0026] Please refer to Figure 4In order to enhance the connection effect between the connecting piece 22 and the connecting pin 21, the connecting piece 22 is further provided with a second connecting hole 22b, the shape of which matches the shape of the connecting groove 21a, and the second connecting hole 22b can be a circular hole. The radial dimension of the first connecting hole 22a is greater than the radial dimension of the second connecting hole 22b, and the first connecting hole 22a and the second connecting hole 22b are sequentially provided on the connecting piece 22 along the first direction. The first connecting hole 22a intersects with the second connecting hole 22b, and the area of ​​the intersection of the second connecting hole 22b and the first connecting hole 22a is greater than one-half of the total area of ​​the second connecting hole 22b, so that the connecting pin 21 can enter the second connecting hole 22b from the first connecting hole 22a. In the connected state, when the connecting pin 21 passes through the first connecting hole 22a along the second direction, the compression state of the first elastic element 23 is released, and the first elastic element 23 rebounds in the opposite direction of the first direction to make the connecting groove 21a fall into the second connecting hole 22b for locking.

[0027] Please refer to Figure 3 In order to prevent the connecting pin 21 from falling out of the connecting assembly 2, a connecting groove 21a is provided at the end of the connecting pin 21, and a limiting groove 21b is further provided in the middle of the connecting pin 21, and the limiting groove 21b is spaced apart from the connecting groove 21a along the second direction. The connecting assembly 2 also includes a limiting piece 24, which is disposed below the connecting piece 22, and the limiting piece 24 can be detachably mounted on the frame of the display module 1, and the limiting piece 24 is spaced apart from the connecting piece 22. The limiting piece 24 is connected in cooperation with the limiting groove 21b of the connecting pin 21 to prevent the connecting pin 21 from falling out of the connecting assembly 2.

[0028] Please refer to Figure 6 In other embodiments, the length of the connecting groove 21a along the axial direction of the connecting pin 21 is greater than the distance between the frames of the two display modules 1, and the limiting piece 24 is arranged below the connecting piece 22. The limiting piece 24 is detachably mounted on the frame of the display module 1, and the limiting piece 24 is spaced apart from the connecting piece 22. The limiting piece 24 is connected with the connecting groove 21a of the connecting pin 21 to prevent the connecting pin 21 from falling out of the connecting assembly 2.

[0029] Please refer to Figure 3 In order to facilitate the connection pin 21 to penetrate the first connection hole 22a, one end of the connection pin 21 facing the connection sheet 22 is obliquely arranged along its axial direction to form a truncated cone 25, and the truncated cone 25 is arranged at a distance from the connection groove 21a. When the connection pin 21 approaches the first connection hole 22a along the second direction, the obliquely arranged truncated cone 25 makes it easier for the connection pin 21 to enter the first connection hole 22a, thereby preventing the connection pin 21 from getting stuck at the edge of the first connection hole 22a.

[0030] Please refer to Figure 3In other embodiments, the connecting pin 21 also includes an operating handle 26, which is movably connected to one end of the connecting pin 21 away from the connecting piece 22. The operating handle 26 can be threadedly connected to the end of the connecting pin 21 away from the connecting piece 22, and the operating handle 26 is used to drive the connecting pin 21 close to the connecting piece 22.

[0031] In a preferred embodiment, a second elastic element 27 is further included, and the second elastic element 27 can be a spring. The second elastic element 27 is sleeved on the connecting pin 21 and clamped between the limiting plate 24 and the operating handle 26. When the connecting pin 21 is away from the first connecting hole 22a of the connecting plate 22, the second elastic element 27 is in an extended state. When the connecting pin 21 is close to the first connecting hole 22a of the connecting plate 22, the second elastic element 27 is in a compressed state.

[0032] Please refer to Figure 3 The display screen further includes a first cover plate 28 and a second cover plate 29, which are detachably arranged on the frames of two adjacent display modules 1 and form a receiving space. The first cover plate 28 can be installed above the frames of two adjacent display modules 1, and the second cover plate 29 can be installed below the frames of two adjacent display modules 1. The connecting pin 21, the connecting piece 22 and the first elastic element 23 can be accommodated in the receiving space. In the connected state, the connecting pin 21 sequentially passes through the second cover plate 29, the frame of the display module 1, the first connecting hole 22a and is exposed on the first cover plate 28.

[0033] Please refer to Figure 5 In order to prevent the first elastic element 23 from bouncing the connecting piece 22 off, the connecting piece 22 is further provided with a strip hole 22c, and the strip hole 22c, the first connecting hole 22a and the second connecting hole 22b are sequentially provided on the connecting piece 22 along the first direction. A protruding column is provided on the first cover plate 28 or the frame of the display module 1 connected to the connecting piece 22, and the shape of the protruding column matches the shape of the strip hole 22c. The protruding column falls into the strip hole 22c, and when the first elastic element 23 rebounds the connecting piece 22, the protruding column can limit the first elastic element 23 from bouncing the connecting piece 22 off.
