Abstract

The invention discloses a box body, an LED display screen and an LED splicing screen. The box body includes a frame body used for mounting an LED display module. The frame body includes a first rim and a second rim arranged oppositely. A first neck is arranged in the back side of the first rim and a second neck is arranged in the back side of the second rim. The first neck and the second neck are arranged oppositely and the openings of the first neck and the second neck are both arranged upward. The box body also includes a side lock including a pivot extending upwards and downwards and a cross rod connected with the pivot. The pivot is pivoted to the first rim and the cross rod can rotate to the back side of the first rim through the pivot and protrudes from the frame body. The pivot can move upwards and downwards so as to drive the cross rod to move upwards and downwards along the back side of the first frame. Further, the cross rod can engage or disengage with/from the first neck and a second neck in a second frame of an adjacent box body. When in engagement, the cross rod locks the two adjacent box bodies. When in disengagement, the cross rod unlocks the two box bodies. When the box body provided by the invention is applied to the LED splicing screen, the LED splicing screen mounting efficiency and dismounting efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of LED display devices, in particular to a cabinet, an LED display screen and an LED splicing screen. Background technique [0002] The LED splicing screen mainly uses the form of splicing to combine multiple LED displays together to form a display screen of any size. At present, LED splicing screens have been widely used in outdoor screen walls, indoor and outdoor stadiums, airport stations, traffic instructions and other fields to display advertisements, race conditions, flight information and traffic conditions. [0003] Existing LED splicing screens are usually formed by splicing multiple LED display screens by screw locking. Among them, one LED display screen is used as a splicing unit. When splicing, screws and Nuts are installed to achieve splicing. However, during assembly, the screw locking method needs to install a large number of screws and nuts, resulting in a large workload of installation ope...
