The adjusting member 130 is provided with a plurality of sockets 131, and the shortest distances from the bottoms of the plurality of sockets 131 to the display screen box 2 are different. The second alignment assembly 20 includes a locking member 230, the locking member 230 being movable relative to the display housing 2. The locking piece 230 is provided with an insertion block 231 which can be matched with the sockets 131, and when the locking piece 230 is positioned at the first position, the insertion block 231 is matched with one socket 131; the locking member 230 is located at the second position where the insert 231 is separated from one of the sockets 131. Therefore, the insert 231 is matched with different sockets 131, so that the adjusting piece 130 and the locking piece 230 can be connected with different height differences.
Further, in the above embodiment, specifically, the adjusting member 130 is movable in the X-axis direction with respect to the display panel casing 2, and the adjusting member 130 is moved in the X-axis direction to switch the socket 131 corresponding to the insertion block 231. The locking member 230 is movable in the Y direction with respect to the display screen housing 2, and the locking member 230 is switched between the first position and the second position by moving in the Y direction, thereby engaging or disengaging the insertion block 231 with or from the insertion opening 131.

In one embodiment, the locking member 230 further includes an elastic plate 234, a second protrusion 234a is disposed on the elastic plate 234, a plurality of second recesses 211a are disposed in the through groove 211, the second protrusion 234a is engaged with one of the second recesses 211a when the locking member 230 is in the first position, and the second protrusion 234a is engaged with another one of the second recesses 211a when the locking member 230 is in the second position. The second protrusion 234a and the second concave portion 211a matched with the second protrusion 234a are arranged, so that the locking member 230 can obtain a certain degree of limiting effect at the first position and the second position. Therefore, when the locking member 230 is in the first position, the locking member 230 can have a certain position, and the alignment stability of the display cabinet after alignment adjustment can be ensured; when the alignment adjustment is performed, i.e., when the plug 231 is separated from the socket 131, the locking member 230 is maintained in the second position, thereby preventing the locking member 230 from interfering with the adjustment of the adjusting member 130, and improving the convenience of the alignment adjustment.
In the above embodiment, the locking member 230 further includes a second control handle 233, the second control handle 233 is disposed on an end of the locking member 230 away from the insertion block 231, and the second control handle 233 extends out of the second alignment housing 200. The locking member 230 can be controlled to move in the Y-axis direction by the second control handle 233, that is, the second protrusion 234a can be disengaged from the second recess 211a, so as to facilitate the adjusting member 130 to switch the socket 131 inserted into the insertion block 231.
In some embodiments, the first alignment housing 100 and the second alignment housing 200 have the same shape and volume dimensions. In other words, the first alignment housing 100 and the second alignment housing 200 are interchangeable, thereby reducing the manufacturing cost and facilitating the replacement of the first alignment housing 100 and the second alignment housing 200 when the components are damaged.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
