Embodiment 1

[0019] A front-moving rear-maintenance LED display described in Embodiment 1, as shown in the figure, includes a frame 1, a support plate 2 fixedly connected to the left and right sides of the frame at both ends, and an LED display fixedly installed on the front of the frame. Module 3, a power supply box 4 that provides power to the LED display module, and a cavity 5 for accommodating the power supply box. The LED display module includes 4 fixing plates 6 that are perpendicular to the support plate and fixedly connected with the frame, and fixed installation The LED display unit 7 on the fixing plate.

[0020] In this embodiment, the cross section of the fixing plate is "ㄇ" shape, and the LED display unit is fixed and mounted on the convex surface of the fixing plate by screws. Using screws to fix the LED display unit can ensure the stable installation of the LED display unit, and the screws are cheap and easy to purchase, easy to assemble and replace, and can reduce the produ...

Embodiment 2

[0024] The front-moving and rear-maintenance LED display provided in Embodiment 2 is modified on the basis of Embodiment 1; the main difference is that LED displays are installed on the front and back of the frame 8 Module 9 has a double-sided display function; and embodiment 1 is equipped with an LED display module on the front side of the frame, which has a single-sided display function. details as follows:

[0025] In this embodiment 2, the LED display module includes four fixed plates 11 perpendicular to the support plate 10 and fixedly connected to the frame, and an LED display unit 12 fixedly mounted on the fixed plate. The fixed plates are mirror-symmetrically arranged on the support plate. On both sides of the same side, the fixed plates on the same side are equally spaced apart. At this time, the LED display is a double-sided LED display. The support plate and the fixing plates on both sides cooperate with the frame to form a closed cavity 13, and the power supply b...

Abstract

The invention discloses a front movement and back maintenance type LED display screen. The front movement and back maintenance type LED display screen comprises a frame, a bearing plate with the two ends fixedly connected to the left and right side edges of the frame, an LED display module fixedly installed on the front side and / or back side of the frame, a power supply box providing power for the LED display module, and a cavity containing the power supply box. The LED display module comprises a plurality of fixing plates which are perpendicular to the bearing plate and are fixedly connected with the frame, and LED display units fixedly installed on the fixing plates. Through structural transformation, the structure of an existing front movement and back maintenance type LED display screen is simplified, and the overall weight of the LED display screen is reduced; the LED display screen is simple in structure, easy to produce, low in manufacturing cost and flexible in design, the LED display screen can be switched between single-side display and double-side display according to use needs, and the application range is wide.

Description

technical field [0001] The invention relates to the technical field of LED displays, in particular to a front-moving rear-maintenance LED display screen. Background technique [0002] LED display (LED display) is a flat-panel display, which is generally used to display various information such as text, images, videos, and video signals. Due to the fact that the area of ​​the LED display can be extended arbitrarily, and seamless splicing can be realized, coupled with its many advantages such as high brightness, low working voltage, low power consumption, large size, long life, impact resistance and stable performance, it is now available It is widely used in outdoor advertising. [0003] The existing front-moving and rear-maintaining LED displays are generally composed of an installation box, an LED display module installed in the installation box, and a rear cover that fixes the LED display module in the installation box. The structure of this LED display Complex, overall ...
