(3) Since the first clamping structure 40 and the second clamping structure 50 are arranged at intervals in the width direction of the rear cover 20, the first end of the rear cover 20 is prevented from tilting relative to the box body 10 in the width direction of the rear cover 20 by using the first clamping piece 41 and the second clamping piece 42 which are matched in a clamping manner and the third clamping piece 51 and the fourth clamping piece 52 which are matched in a clamping manner, so that the first end of the rear cover 20 is reliably connected with the box body 10;

(4) Because the inclined surface 321 is arranged on one side of the plugging boss 32, which is far away from the rear cover 20, in the process of disassembling the rear cover 20, the rear cover 20 is rotated by taking the lower end of the rear cover 20 as a rotation axis, so that the plugging boss 32 is inserted into the plugging port 31 or the plugging boss 32 is pulled out from the plugging port 31, the labor intensity of the assembly is further reduced, and the disassembling efficiency of the rear cover 20 of the display screen box body is improved;

(5) The elastic deformation of the elastic piece 411 is utilized to realize repeated clamping of the first clamping boss 412 and the second clamping boss 421, so that the first clamping structure 40 can be reused, the detachable connection of the first clamping boss 412 and the second clamping boss 421 is realized, and the service life of the first clamping structure 40 is prolonged;

(6) In the process of repeated clamping and matching of the third clamping boss 512 and the fourth clamping boss 521, the hemispherical structure can play a role in guiding, so that resistance is reduced, abrasion is reduced, and service life is prolonged.

The above description is only of the preferred embodiments of the present utility model and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
