Embodiment 1
[0035] Such as figure 1 , figure 2 and Figure 4 As shown, this embodiment proposes a display assembly, which specifically includes: a display body 1 , a mounting frame 2 and a fool-proof structure. Wherein, the display body 1 is provided with a plurality of conductive structures 11, and the mounting frame 2 is provided with a plurality of sockets 21, the sockets 21 are consistent with the number of the conductive structures 11, and are provided in one-to-one correspondence (that is, each conductive structure 11 can only into the corresponding socket 21). The fool-proof structure includes a first engaging part 31 and a second engaging part 32 ; wherein, the first engaging part 31 is arranged on the display body 1 , and the second engaging part 32 is arranged on the installation frame 2 . When fixing the display body 1 on the mounting frame 2, the first engaging part 31 and the second engaging part 32 of the fool-proof structure need to be engaged to ensure that each conduc...
Embodiment 2
[0042] Such as figure 1 , figure 2 and Figure 4 As shown, this embodiment provides a display assembly. Compared with Embodiment 1, the display assembly of this embodiment further includes a turnbuckle structure. Wherein, the turnbuckle structure includes: a slot 41 and a protruding structure 42 . In the following, the card slot 41 is set on the display body 1, and the protruding structure 42 is set on the mounting frame 2 as an example for illustration. Of course, it is also feasible to set the protruding structure on the display body 1, and the card slot is set on the mounting frame 2. .
[0043] Preferably, the card slot 41 is arranged on the display body 1; the card slot 41 includes a first groove and a second groove, figure 1 The center is in an inverted L shape, the second groove communicates with one end of the first groove, and the size of the second groove is smaller than that of the first groove. The protruding structure 42 is arranged on the mounting frame 2, ...
Embodiment 3
[0047] Such as figure 1 , Figure 6 As shown, the present embodiment provides a display assembly. Compared with the above-mentioned embodiments, the display body 1 of the present embodiment is provided with a circle of first bosses 12, and the first bosses 12 surround all conductive structures. Correspondingly, the mounting bracket 2 is provided with a circle of second bosses 22 surrounding all the sockets 21 . Wherein, the size of the first boss 12 is adapted to the size of the second boss 22 , so that when the display body 1 is installed on the mounting frame, the first boss 12 is buckled inside the second boss 22 .
[0048] Preferably, when the display assembly of this embodiment is provided with a turnbuckle structure, there are at least two turnbuckle structures, and the slots 41 of the turnbuckle structures are evenly distributed on the outer wall of the first boss 12; correspondingly , the protruding structures 42 of the turnbuckle structure are evenly distributed on ...
