Abstract

The utility model discloses a box body, comprising: the buffer piece comprises a body, a first connecting piece and a second connecting piece, wherein the body is provided with a first side wall and a second side wall corresponding to the first side wall; and the second side wall is provided with a fitting piece matched with the connecting piece. When the two box bodies are spliced, the screw on one box body is in threaded connection with the mounting hole on the other box body, and the two box bodies are tensioned. The two boxes compress the buffer sheet between them. The buffer sheet can be compressed to provide certain elasticity and friction force. By means of elasticity and friction force of the buffer sheet, the situation that a seam exists between the two boxes can be avoided, the positions of the boxes can be finely adjusted, and the boxes are aligned.

Description

Box and LED display screen

Technical Field

The utility model relates to the technical field of LEDs, in particular to a box body and an LED display screen.

Background

The LED small-spacing spliced screen has the characteristics of clear display, high contrast, high brushing, low brightness, high gray and the like. The gray point of the LCD screen is far lower than that of the traditional LCD screen, the gray level can be captured (displayed) by monitoring the light and shade difference of a little point below the LCD screen, and seamless splicing can be realized. And can be spliced infinitely theoretically without size limitation. Therefore, the method is widely applied to security monitoring, municipal administration, dispatching rooms, command rooms and the like, and has a huge market prospect.

The basic unit for forming the LED small distance is a box body, the box body is a minimum screen body for forming the LED small distance, all the small distance screens are formed by the box body of the minimum unit, and the small distance LED display screens are formed by splicing a plurality of same minimum box bodies. Therefore, the boxes are spliced into components with increasingly important small spacing between screens.

The existing box bodies are generally connected by metal (die-cast aluminum) and are rigid bodies. After the micro-deformation, the two adjacent sides of the box body are not perpendicular, so that the two spliced sides of the two box bodies cannot be completely overlapped, the splicing of the two box bodies is influenced, the next adjacent box body is influenced, and the splicing of the whole screen is influenced.

The two boxes are rigid objects, if the boxes are distorted and deformed during processing, the planes of the boxes are dislocated and have a fault difference after the two boxes are locked, and the screen body is spliced.

When two boxes splice, the screw is taut back, causes horizontal plane and vertical dislocation easily, because two boxes are the metal covering hard contact, does not have the buffering area fine setting, and the screw is the steel screw, and the pulling force far exceeds die-casting aluminium ADC 12's bearing capacity, if the screw is not taut, does not play the fixed action of two screens bodies, if slightly draws excessively, causes the screen body to warp very easily.

SUMMERY OF THE UTILITY MODEL

In order to solve at least one technical problem in the background art, the utility model provides a box body and an LED display screen.

The utility model provides a box body, which comprises:

the buffer piece comprises a body, a first connecting piece and a second connecting piece, wherein the body is provided with a first side wall and a second side wall corresponding to the first side wall; and the second side wall is provided with a fitting piece matched with the connecting piece.

Preferably, the body has a third sidewall and a fourth sidewall corresponding to the third sidewall, and the third sidewall is provided with the buffer sheet and the connecting member; the fourth side wall is provided with the matching piece.

Preferably, the four side walls of the body are respectively provided with the buffer sheet, the connecting piece and the matching piece; wherein any of the connectors is engaged with the mating member opposite thereto.

Preferably, the buffer sheet is bonded to the body through a back adhesive.

Preferably, the connecting piece is a screw; the fitting piece is a mounting hole.

The utility model provides a box concatenation form that LED display screen, this LED display screen the box.

The beneficial effects brought by one aspect of the utility model are as follows:

when the two box bodies are spliced, the screw on one box body is in threaded connection with the mounting hole on the other box body, and the two box bodies are tensioned. The two boxes compress the buffer sheet between them. The buffer sheet can be compressed to provide certain elasticity and friction force. By means of elasticity and friction force of the buffer sheet, the situation that a seam exists between the two boxes can be avoided, the positions of the boxes can be finely adjusted, and the boxes are aligned.

Detailed Description

It should be noted that, in the case of no conflict, the embodiments and features in the embodiments in the present application may be combined with each other; the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left" and "right", etc., indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the positions or elements referred to must have specific orientations, be constructed in specific orientations, and be operated, and thus are not to be construed as limitations of the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

Referring to fig. 1 and 2, the present invention provides a box body, including:

the body 2 is provided with a first side wall and a second side wall corresponding to the first side wall, the body 2 is provided with a third side wall and a fourth side wall corresponding to the third side wall, and the first side wall is provided with a buffer sheet 1 and a connecting piece 3; and the second side wall is provided with a fitting part 4 matched with the connecting part 3. The second side wall is provided with a buffer sheet 1 and a connecting piece 3; and a fitting part 4 matched with the connecting part 3 is arranged on the first side wall.

The third side wall is provided with the buffer sheet 1 and the connecting piece 3; the fitting piece 4 is arranged on the fourth side wall.

The fourth side wall is provided with a buffer sheet 1 and a connecting piece 3; and a fitting part 4 matched with the connecting part 3 is arranged on the third side wall.
