Abstract

The utility model relates to an LED display screen assembly, which adopts the technical scheme that the LED display screen assembly comprises a bottom housing and face guards; and a PCB substrate matched with the assembly is mounted in the assembly. The assembly further comprises a mesh frame which is mounted on the PCB substrate in the bottom housing, the PCB substrate is fixed between the mesh frame and the bottom housing, and the face guards are fixed on the mesh frame through buckles. The LED display screen assembly provided by the utility model has the advantages that the face guards have small areas and the bottom housing can be matched with the plurality of the face guards, solving the problems of inconsistent ink color and poor flatness of the display screen, and ensuring that the assembled display screen is flat and consistent in color; the face guards and the mesh frame are in direct buckle fixation, so that the operation is simple; and movable sexangular copper pillars are arranged on the bottom housing, so that the assembly can be movably connected forwards and backwards, so as to facilitate maintenance.

Description

A kind of LED display external member

Technical field

The utility model relates to a kind of LED display external member.

Background technology

LED display has become the sign of urban information modernization construction as a kind of important means of information propagation.Along with socioeconomic continuous progress, and the LED display technique is constantly perfect, and people will more and more go deep into the understanding of LED display, and its application will be more and more wider.In the existing LED dot matrix screen, great majority are that shell, framework, pcb board are wholely set, the three does not separate, in maintenance, very inconvenient when installing, and it is bad at LED dot matrix screen waterproof effect and shaded effect, be very easy to short circuit or damage, in the process of using the LED dot matrix, brought inconvenience for the user.And all the producing of these problems because of the LED display external member.

The utility model content

The purpose of this utility model is exactly the shortcoming that will overcome above-mentioned prior art, and the LED display external member that small mask is installed on a kind of drain pan is provided.

The technical solution of the utility model is: a kind of LED display external member, comprise drain pan and face shield, the PCB substrate that matches can be installed in the external member, described external member also includes rack, this rack is installed on the interior PCB substrate of drain pan, the PCB substrate is fixed in the middle of rack and the drain pan, and face shield utilizes snap fit on rack.

The described face shield back side is provided with buckle, and face shield is fixed by snap on rack.

Described drain pan is provided with hexagonal copper post, and described hexagonal copper post is movably arranged on drain pan.

Described face shield is made up of a plurality of small masks, and described facet is covered with six.

Described drain pan periphery has the convex-concave point that breaks away between the external member of preventing.

Described face shield periphery is provided with the convex-concave point identical shaped with drain pan.

The beneficial effects of the utility model are: the first, the LED display external member that provides of the utility model, and the design of face shield small size, a drain pan is joined a plurality of face shields; Solved the problem of the inconsistent and flatness injustice of mass colour in the display screen, made after the display screen assembling not only smooth but also solid colour.

The second, the LED display external member that provides of the utility model, face shield is fixing not to be screwed, and directly and the rack snap fit, both saves time, and screw is can't see on the face shield surface again, and is attractive in appearance again.

Three, the LED display external member that provides of the utility model, rack is imbedded in the casting glue of water proof ring, accounts for certain volume, saves the casting glue use amount, saves cost.

Four, drain pan design activity hexagonal copper post can make the external member front and back flexibly connect, with convenient for maintaining.
