Abstract

The utility model discloses an LED display screen which is formed by assembling a plurality of separate unit display screens; every unit display screen comprises a display screen box body, a back door, a display module, and connecting devices; the display screen box body, the back door, and the display module are connected respectively through connecting devices; the display screen box body is a permeable cuboid frame structure with single side or multiple sides, which are formed by assembling at least twelve hollow shaped materials vertical to each other; L-shaped or strip-shaped connecting pieces are arranged on the inner wall of the shaped material vertical to the end opening of the shaped material or on the outside connection position; the connecting piece is fixed with the shaped material through bolts, rivets, or pins. The display screen of the utility model is formed by assembling the shaped materials, and the connecting pieces and fasteners are used for enhancing the frame intensity, so that the whole frame is prone to stable; since every unit box body uses the permeable modes with single side or multiple sides, a good ventilation and heat emission environment is provided; since the section size of the shaped material is ensured as demoulding, the shaped material is just required to be processed on a common milling machine to reduce the requirement for the equipments.

Description

A kind of LED display
Technical field
The utility model relates to a kind of display screen, is meant a kind of indoor large display screen specifically.
Background technology
At present, the indoor large display screen that sell in existing city, its body structure adopt the structure of outdoor display screen mostly, and promptly by being spliced after the sheet material bending, though this structure is firm reliable, operation is various, the accuracy requirement height of processing, and labour intensity is big, the cost height.Simultaneously and since large display screen by several independently the small display casing constitute, each tank surface is provided with the independent protection layer, causes the result of ventilating heat dissipation in the whole large display screen poor.Also once had the report of this architecture advances, the patent that is called " electronic display structure with assembled lightweight steel framework " as No. 01239017.8 name of Chinese patent, this display screen structure framework adopts cold-forming shapes as support, connect by assembled between rack material, its rigidity intensity is increased greatly, provide good ventilating heat dissipating environment, but it is too complicated to study carefully its structure, is blemish in an otherwise perfect thing really.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, economical and practical indoor large display screen.
The utility model can be achieved through the following technical solutions:
A kind of LED display, independently the unit display screen is assembled by several, each unit display screen comprises display screen box body, back door, display module and coupling arrangement, display screen box body, back door and display module connect by coupling arrangement separately, described display screen box body combines single face or the penetrating space frame structure of multiaspect by at least 12 orthogonal frame members, frame member and frame member port inner vertical walls or outside joint are provided with the web member of L-shaped or bar shaped, are fixed by fastener bolt, rivet or bearing pin between web member and frame member.
Described frame member is a hollow material.
When described web member was built-in, section bar port joint had the window that web member is installed.
The utility model has following advantage than prior art:
The utility model display screen is spliced by section bar, comes reinforced frame intensity by web member, securing member, and whole framework is tended towards stability.Because each unit box adopts single face or the penetrating mode of multiaspect, therefore provide good ventilating heat dissipating environment.Simultaneously and since the sectional dimension of section bar when going out mould also through well being guaranteed, only need to get final product in common milling machine processing, reduced requirement to equipment.
Description of drawings
Fig. 1 is the utility model display screen box body schematic perspective view.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
With reference to accompanying drawing, independently the unit display screen is assembled by several for the utility model, each unit display screen comprises display screen box body, back door, display module and coupling arrangement, display screen box body, back door and display module connect by coupling arrangement separately, described display screen box body combines the penetrating rectangular parallelepiped framed structure of multiaspect by 16 orthogonal frame members 1, frame member and frame member port inner vertical walls or outside joint are provided with the web member 2 of L-shaped or bar shaped, are fixed by fastener bolt, rivet or bearing pin between web member and frame member.
Described frame member is a hollow material.
When described web member was built-in, section bar port joint had the window that web member is installed.
The utility model can decide the quantity of unit box according to the size of indoor display screen.
Each unit box is spliced by the hollow material frame member, adopt a sign indicating number son to fix between frame member or can on the sign indicating number son, attack internal thread, by being threaded each several part is stitched together, framework one side is used for fixing display module, opposite side is used for fixing the annex that is placed on back door and the door, web member, securing member are used for the intensity of reinforced frame, and the general frame structure is tended towards stability.
Add man-hour, only need process section bar and a sign indicating number son and get final product, significantly reduced requirement equipment with common milling machine, during assembling, only need fix, can reduce the number of times of welding effectively, guarantee the size of display screen box body itself better with screw and nut.Owing to adopt the section bar splicing, can guarantee to reduce the weight of self to greatest extent on the solid and reliable basis of framework.Simultaneously, because each unit box adopts single face or the penetrating mode of multiaspect, therefore provide good ventilating heat dissipating environment for entire display screen inside.

Claims (5)
