Description

The LED display modular structure of safeguarding before a kind of being easy to
Technical field
The utility model relates to LED display, more particularly, relates to the LED display modular structure of safeguarding before a kind of being easy to.
Background technology
LED display is that the lattice module or the pixel cell that utilize the LED electroluminescent lamp to constitute are formed on the area display screen, and it has been widely used in various occasions such as indoor outer advertisement, physical culture, traffic, performance, exhibition, lease, rally with good reliability, characteristics that cost performance is high.
And LED display in use, and its maintenance is also become indispensable link.At different LED display, safeguard with the back before maintaining method can be divided into and safeguard two kinds.Some are applied to the LED display of outdoor giant-screen, because of its display screen box body volume, weight all bigger, and the reasons such as complex circuit of LED display lamp plate, the general back maintaining method that adopts, the structure of its display screen also is designed to be easy to the frame mode that safeguard the back; And for some indoor the small screen LED display, maintaining method before adopt more, though whether this maintaining method can accurately and timely be observed the positive surface evenness of LED display qualified, but because some indoor LED display modular structures adopt screw to be installed on the LED casing more at present, when safeguarding before carrying out, need screw is removed one by one, this process is not only loaded down with trivial details, and causes the damage of module parts easily.
The utility model content
Technical problem to be solved in the utility model is to provide the LED display modular structure of safeguarding before a kind of being easy to.
For solving the problems of the technologies described above, the technical solution of the utility model is: the LED display modular structure of safeguarding before a kind of being easy to is provided, be fixedly arranged on the LED display casing, comprise the module backboard that is connected with described LED display casing and be fixedly arranged on the module backboard and be provided with the pcb board of LED lamp, be movably equipped with some magnetic elements that can be connected between described module backboard and the described pcb board with described LED display casing magnetic.
Further, described magnetic element is block magnet.
Further, described module backboard and described pcb board joint face are provided with storage tank, and described block magnet places in the described storage tank, are provided with the insulation glue-line on the described pcb board and with described storage tank corresponding position.
LED display modular structure in the utility model is in working order the time, magnetic absorption by magnetic element and LED display casing is fixed, when before need carry out, safeguarding, only need by the magnetic instrument see through pcb board absorption magnetic element it is overcome and the LED display casing between magnetic force move near pcb board, thereby the LED display modular structure can be taken off from the LED display casing, than the modular structure that needs knockout screw in the prior art, LED display modular structure in the utility model is dismantled simpler when preceding safeguarding, convenient, can not cause damage, guarantee the integrality of modular structure the module parts.

Embodiment
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Please refer to Fig. 1, be the partial schematic sectional view of a preferred embodiment of the present utility model.Described LED display modular structure, be fixedly arranged on the LED display casing 1, comprise the module backboard 2 that is connected with described LED display casing 1 and be fixedly arranged on the module backboard 2 and be provided with the PCB plate 3 of LED lamp (not shown), be movably equipped with some magnetic elements 4 that can be connected between described module backboard 2 and the described pcb board 3 with described LED display casing 1 magnetic.LED display modular structure in the utility model is in working order the time, fix by the magnetic element 4 and the magnetic absorption of LED display casing 1, when before need carry out, safeguarding, only need by the magnetic instrument see through pcb board 3 absorption magnetic elements 4 it is overcome and LED display casing 1 between magnetic force move near pcb board 3, the LED display modular structure can be taken off from LED display casing 1, than the modular structure that needs knockout screw in the prior art, LED display modular structure in the utility model is dismantled simpler when preceding safeguarding, convenient, can not cause damage, guarantee the integrality of modular structure the module parts.
Below each ingredient of present embodiment is further described in detail.
See figures.1.and.2, the magnetic element of being located between described module backboard 2 and the pcb board 34 is block magnet 41.Described module backboard 2 is provided with some storage tanks 21 with pcb board 3 joint faces, and described block magnet 41 places in the described storage tank 21.Among the utility model embodiment, LED display casing 1 is made for iron material, when the LED display modular structure is in running order, thereby block magnet 41 sees through fixedlying connected of module backboard 2 and LED display casing 1 absorption realization LED display modular structure and LED display casing 1, under this state, block magnet 41 is positioned at a side of storage tank 21 and close module backboard 2.Simultaneously, produce the short circuit that magneticaction causes pcb board 3, be provided with insulation glue-line 31 on the described pcb board 3 and with described storage tank 21 corresponding positions in order to prevent block magnet 41 and pcb board 3.
