LED display screen and display screen lock

Abstract

The application provides an LED display screen and a display screen lock. The display screen lock comprises a top cover, a base, a sliding lock and a double-curved tooth rod. The base is connected below the top cover and has an arc-shaped sliding slot. The sliding lock comprises a splicing surface, a lock slot and an arc-shaped lock tongue. The lock tongue is arranged in the sliding slot and has a first sliding hole along the arc length direction. A double-curved gear is arranged on the hole wall. The splicing surface is located outside the sliding slot and is connected with the lock tongue. The lock slot is arranged on the splicing surface and faces the lock tongue. One end of the double-curved tooth rod is inserted into the first sliding hole through the top cover, and the other end is arranged outside the top cover. The double-curved tooth rod and the double-curved gear are engaged with each other, and the axes of the double-curved tooth rod and the double-curved gear are not parallel and not perpendicular. In the application, rotating the double-curved tooth rod can drive the lock tongue to slide in the sliding slot relative to the base through the double-curved gear, so as to adjust the angle of the base and the splicing surface, that is, the splicing angle of the display screen lock is changed. The structure is simple and convenient to operate, and the splicing angle is rich, so that the display screen splicing with various radii can be realized.
