Box body of LED display screen

Abstract

The invention discloses a box body of an LED display screen, and belongs to the technical field of LED display screens. The box body comprises a box body frame, a display module, an electromagnetic lock and a lock control device. At least one pair of lock catches or electromagnetic locks are arranged on the back face of the display module. An electromagnetic lock or a lock catch corresponding to each lock catch or each electromagnetic lock is arranged on the box body frame; the display module is attracted to the box body frame through the magnet, the spring bolt of the electromagnetic lock ismatched with the lock catch, and the display module is fixed to the front face of the box body frame. The lock control device is fixed to the back face of the box body frame or the display module andcontrols the spring bolt of the corresponding electromagnetic lock to stretch out or retract back according to the received information, when the spring bolt stretches out, the spring bolt stretches into the lock catch to fix the display module to the box body frame, and when the spring bolt retracts back, the spring bolt is disengaged from the lock catch, so that the display module is disengagedfrom the box body frame. According to the invention, the display module can be prevented from accidentally falling off, a mechanical hole does not need to be used for penetrating operation in the module panel, the module panel can be used for a display screen with a smaller pixel point distance, and the module is convenient to maintain, disassemble and assemble.
