In summary, existing display screen obviously exists inconvenience and defective on reality is used, so be necessary to be improved.
The utility model content
At above-mentioned defective, the purpose of this utility model is to provide a kind of display screen, and it can directly take off lamp plate from the front of display screen and safeguard, has reduced maintenance cost, and is convenient to produce and install.
To achieve these goals, the utility model provides a kind of display screen, and the casing that comprises lamp plate and be used for fixing described lamp plate is installed with magnetic on the described lamp plate, and the magnetic force of described lamp plate by described magnetic is fixed on the described casing.
According to display screen of the present utility model, welding is provided with reference column on the described lamp plate.
According to display screen of the present utility model, described casing is provided with the pilot hole that matches with described reference column, and described reference column embeds described pilot hole.
According to display screen of the present utility model, described reference column is fixed in described lamp plate by the mode of welding.
According to display screen of the present utility model, described magnetic is a flat thin magnet.
According to display screen of the present utility model, described flat thin magnet is fixed in described lamp plate by the mode of welding.
According to display screen of the present utility model, the thickness sum of described lamp plate and described magnetic is not more than 7mm.
According to display screen of the present utility model, described lamp plate is a pcb board.
According to display screen of the present utility model, described display screen is a LED display.
The utility model is by setting firmly a magnetic on lamp plate, magnetic force by magnetic is fixed together lamp plate and casing, when safeguarding, only needs use in the front of display screen greater than the power of magnetic force lamp plate to be taken off to get final product, improve work efficiency, reduced maintenance cost; When lamp plate is installed, only need lamp plate then can be fixed automatically near casing, more more convenient than conventional mounting program.Whereby, the utility model can directly take off lamp plate from the front of display screen and safeguard, has reduced maintenance cost, and is convenient to produce and install.
Preferably, welding is provided with reference column on the lamp plate, and casing is provided with the pilot hole that matches with reference column.By cooperating of reference column and pilot hole, lamp plate just can be installed to preposition on the casing, has improved installation accuracy.And the thickness sum of lamp plate and magnetic is not more than 7mm, helps the ultrathin design of display screen.
