Abstract

An LED display screen convenient to maintain comprises a circuit board, a box body and a heat dissipation plate. The box body is a hollow cuboid. An LED display screen body is arranged at the front portion of the box body, a switch is arranged on the right side of the LED display screen body, and the heat dissipation plate is arranged in the back of the box body and fixed to the box body through a dowel. The outer side wall of the box body is provided with a USB interface. A sliding way is formed in the inner side wall of the box body, and the circuit board is located on the sliding way. Two symmetric lock holes are formed in the upper portion of the circuit board, spring bolts are arranged under the lock holes, and a handle is arranged in the center of the upper portion of the circuit board. When the LED display screen body is damaged, the lock holes in the upper portion of the circuit board can be opened by a key, then the circuit board is pulled out from the sliding way in the box body through the handle to be maintained, and therefore disassembling the circuit board layer by layer is avoided, maintenance is easier and faster, and the work efficiency can be greatly improved.

Description

The LED display of convenient for maintaining
technical field:
The utility model relates to electronic equipments, is specifically related to a kind of LED display of convenient for maintaining.
