Afterwards, the first clamping member 300 is rotated to form an opening on the side wall of the fixed cavity 500, and the installation mullion can be detached from the opening of the fixed cavity 500, so that the mullion can be quickly and easily disassembled and installed. The connection of the frame and the installation horizontal frame is also very convenient, which is convenient for the maintenance of the outer frame of the box.

The present application also provides an embodiment of a display screen, which includes a display module and the outer frame of the cabinet as described in the above embodiment, and the display module is installed on the installation horizontal frame. For the above-mentioned display screen, the display module is installed on the installation horizontal frame of the outer frame of the box, and the installation mullion is connected with the installation horizontal frame through the installation fixing device 10, and the installation mullion is used to improve the strength of the horizontal frame and the entire outer frame of the box. The stability. The display screen to which the above-mentioned installation and fixing device 10 is applied can also achieve corresponding technical effects, which will not be repeated here.

The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, all possible combinations of the various technical features in the above-mentioned embodiments are not described. However, as long as there is no contradiction in the combination of these technical features, All should be considered as the scope of this specification.

The above-mentioned embodiments only express several implementation manners of the present application, and their description is relatively specific and detailed, but they should not be interpreted as a limitation on the scope of the patent application. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of this application, several modifications and improvements can be made, and these all fall within the protection scope of this application. Therefore, the scope of protection of the patent of this application shall be subject to the appended claims.
