Abstract

The utility model relates to an LED display screen which comprises an LED screen display module and a display screen case for fixing the LED screen display module, wherein the LED screen display module comprises a bottom shell, a mask and a PCB lamp panel are fixed on the bottom shell, and the bottom shell and the frame of the display screen case are provided with matched buckling and fixing parts. In the utility model, the fixing of the LED screen display module and the display screen case is realized by the buckling and fixing structure, and the installation and maintenance cost can be greatly increased compared with a screw fixing structure.

Description

A kind of LED display

Technical field

The utility model relates to the LED display field, more particularly, relates to a kind of LED display that mounting box is safeguarded of being convenient to.

Background technology

LED display (LED display) is electronic display again or the word screen that wafts, and is made up of the LED dot matrix, and the light on and off by LED modules with different colors lamp pearl come display text, picture, animation, video etc.LED display has the following advantages: the brightness height, operating voltage is low, power consumption is little, miniaturization, the life-span is long, shock-resistant and stable performance etc.

As shown in Figure 1, LED display is made up of LED screen demonstration module 12 and display screen box body 11 usually, and wherein the LED screen shows that the dot matrix that module 12 is made up of the LED lamp constitutes, and is responsible for luminous demonstration.

In above-mentioned LED display, the LED screen shows that module 12 is fixed to the framework (framework is provided with screw 111) of display screen box body 11 by screw.This mode makes LED display bother very much when I﹠M: just can take off the LED screen after must disassembling screw and show module.And attractive in appearance for LED display, usually LED screen demonstration module 12 need be taken installation apart, promptly earlier the LED screen is shown that the drain pan of module 11 is fixed to the framework of display screen box body 11, and then LED screen shown that the PCB lamp plate and the face shield of module 12 are fixed to drain pan, this makes the installation and maintenance of LED display waste time and energy more.

Summary of the invention

The technical problems to be solved in the utility model is, fixes the defective of the installation and maintenance trouble that causes at existing LED display owing to the LED screen shows module employing screw, and a kind of LED display that mounting box is safeguarded of being convenient to is provided.

The technical scheme that its technical matters that solves the utility model adopts is: a kind of LED display, comprise that the LED screen shows module and is used for fixing the display screen box body that the LED screen shows module, described LED screen shows that module comprises drain pan, be fixed with face shield and PCB lamp plate on the described drain pan, the framework of described drain pan and display screen box body is provided with the snap fit parts that match.

In LED display described in the utility model, described snap fit parts comprise the draw-in groove that is positioned at the grab on the described drain pan and is positioned at the framework of described display screen box body.

In LED display described in the utility model, described grab is positioned at the edge of drain pan.

In LED display described in the utility model, also be provided with support column on the described drain pan, the position that the framework of described display screen box body is corresponding with support column is provided with pilot hole.

In LED display described in the utility model, the hook portion of described grab and the top of support column maintain an equal level.

LED display of the present utility model can reach following beneficial effect: structure fixed by snap has realized that the LED screen shows the fixing of module and display screen box body, can greatly improve the cost of installation and maintenance with respect to the screw fixed sturcture.

Embodiment

Understand for technical characterictic of the present utility model, purpose and effect being had more clearly, now contrast accompanying drawing and describe embodiment of the present utility model in detail.

The utility model is by the grab fixed sturcture between LED screen demonstration module and the display screen box body, realized that the LED screen shows the fixing of module, make the LED screen show that module need not to use screw when mounted, improved production efficiency greatly, made things convenient for the LED screen to show the maintenance of module simultaneously.

Shown in Fig. 2-4, be the structural representation of the utility model LED display embodiment.This LED display 20 comprises that the LED screen shows module 22 and the casing 21 that is used for fixing the LED display module, wherein LED screen shows that module comprises drain pan 221 and is fixed with the PCB lamp plate of face shield (face shield is made of led array), in the side of drain pan 221(towards display screen box body 21) and the framework of display screen box body 21 on be provided with the snap fit parts that match.In the present embodiment, the PCB lamp plate can be fixed to drain pan 221 by modes such as welding, screw, rivet, buckles.

In the present embodiment, snap fit parts between the framework of drain pan 221 and display screen box body 21 comprise the grab 222 that is positioned on the drain pan 221 and are positioned at draw-in groove 211 on display screen box body 21 frameworks that wherein the quantity of grab 222 and draw-in groove 211, position are corresponding one by one.Certainly, in actual applications, also draw-in groove 211 can be located at drain pan 221 and grab 222 be located on the framework of display screen box body; Draw-in groove and grab perhaps are set on drain pan 221 simultaneously, and on the display screen box body framework, draw-in groove are set, grab are set at the draw-in groove correspondence position with drain pan grab correspondence position.

In above-mentioned LED display, in order to guarantee the bond strength between drain pan 221 and the display screen box body 21, can a plurality of grab 222(be set correspondingly at the edge of drain pan 221, at display screen box body 21 framework correspondence positions a plurality of draw-in grooves are set).

In above-mentioned LED display, can on drain pan 221, be provided for against the support column 223 of display screen box body 21 frameworks, the top of the hook portion of grab 222 and support column 223 maintains an equal level, thereby guarantees that drain pan 221 is fixed to display screen box body 21 backs and keeps stable.

In the embodiment of Fig. 2-5, the LED screen shows that the global shape of module 22 is a rectangle, be that drain pan, PCB lamp plate and face shield all are rectangle, the LED screen shows that module also can be other shapes (being that drain pan, PCB lamp plate and face shield all are rectangle) in concrete the application, for example circular (for example traffic indication board), triangle (traffic warning board) etc.

In conjunction with the accompanying drawings embodiment of the present utility model is described above; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment only is schematic; rather than it is restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away under the scope situation that the utility model aim and claim protect, also can make a lot of forms, these all belong within the protection of the present utility model.
