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
technical field:
The utility model relates to electronic equipments, is specifically related to a kind of LED display of convenient for maintaining.
background technology:
LED display has become the requisite instrument of propaganda of each industry, when traditional LED display is keeped in repair, bonnet need to be disassembled, again circuit board is taken out, in this process, bring a lot of inconvenience to maintenance, in order to solve appeal technical matters, spy provides a kind of new technique scheme.
utility model content:
The purpose of this utility model is the weak point existing in order to overcome above-mentioned prior art, and a kind of LED display of convenient for maintaining is provided, and it is easy to use, simple to operate, be easy to large-scale promotion application.
The technical solution adopted in the utility model is: a kind of LED display of convenient for maintaining, comprise circuit board, casing and heat sink, casing is the rectangular parallelepiped of hollow, casing front portion is provided with LED display, switch is positioned at the right side of LED display, casing rear portion is provided with heat sink, heat sink and casing are fixed with pin, the lateral wall of casing is provided with USB socket, the madial wall of casing is provided with slideway, and circuit board is positioned on slideway, and circuit board top is provided with the lockhole of two symmetries, under lockhole, be provided with dead bolt, circuit board central upper portion position is provided with handle.
The beneficial effects of the utility model are: in the time that LED display is damaged, open the lockhole that is located at circuit board top with key, then by handle, circuit board is pulled out from the slideway of box house, thereby carry out the maintenance of circuit board, avoid the dismounting layer by layer of circuit board, make to keep in repair simple and fast more, can increase work efficiency greatly.
brief description of the drawings:
