Abstract
The invention provides a light emitting diode (LED) display screen unit box consisting of contained sections. The LED display screen unit box is characterized by comprising a spliced box framework, wherein a rear cover component is mounted on the rear side surface of the box framework; and an LED circuit component is fixed on the front side surface of the box framework. The invention has the advantages that: the size precision and the angle precision are high and the appearance precision and uniformity of the unit box are guaranteed; welding is not needed, so that defects of unsmooth welding seams and deformed box caused by heating are prevented; sides of the box are concave and convex with each other, and the left side and the right side can be matched, so that the screen surface of the spliced LED display screen is smooth; a plurality of working procedures such as punching, blanking, folding, molding, welding and the like are avoided, so the processing error and deformation are prevented; the box is convenient to manufacture; the efficiency and the yield are improved; the screen surface of the spliced LED display screen is smooth; an array of LED lamps is orderly; and the gap between the boxes is small, and the improvement effect is remarkable.
Description
Technical field
The present invention relates to a kind of LED display structure casing.
Background technology
The structure housing of a lot of large LED display screens is spliced by the unit box that the led circuit assembly is housed, and this form accuracy and coherence request to unit box is very high.Usually the framework of unit box adopts sheet metal, after punching and blanking, the flanging moulding, four angle seam cracks is welded; Leading flank fixedly mounts the led circuit assembly then, and trailing flank is loaded onto rear case component.This structure makes box shape size discreteness big easily, case corner degree is difficult for meeting at right angles, plate sheet welding processing request height, efficient is low, the weld seam out-of-flatness makes the casing temperature distortion, causes between uneven straight, the casing of the out-of-flatness of the mutual spliced LED display panel of unit box, LED lamp array defectives such as the slit is big, and the screen body is big more, and defective more very.The structure housing of LED display presses for a kind of overall dimension consistency height, right angle, case limit precision height, unit box easy to process.
Summary of the invention
The purpose of this invention is to provide a kind of overall dimension consistency height, right angle, case limit precision height, unit box easy to process.
In order to achieve the above object, technical scheme of the present invention has provided a kind of by comprising the LED display unit box that section bar constitutes, it is characterized in that: comprise the box frame that is spliced, trailing flank at box frame is equipped with rear case component, and the led circuit assembly is fixed on the leading flank of box frame.
Further, described box frame is spliced by the upper cover plate, the lower cover that are positioned at two ends up and down and the front panel that is positioned at left side post, the right side post of the left and right sides and is positioned at the front side.
Be provided with at least one center pillar between described left side post and described right side post, the two ends up and down of center pillar link to each other with described upper cover plate and described lower cover respectively.
The two ends up and down of described left side post, right side post and center pillar link to each other with described upper cover plate and described lower cover by screw respectively.
Described left side post, right side post and center pillar are section bar, are provided with at least one open loop hole on the section bar cross section, in the inside fire attack of open loop hole screw thread are arranged.
Outwardly side has groove when described left side post is installed, outwardly side is provided with rib when described right side post is installed, or outwardly side is provided with rib when described left side post is installed, and outwardly side has groove when described right side post is installed, and agrees with mutually between rib and the groove.
The invention has the beneficial effects as follows: size, angle precision height guarantee unit box form accuracy and consistency to some extent; Need not weld, exempt the shortcoming of weld seam out-of-flatness, casing temperature distortion; The casing side is concavo-convex each other, about can agree with mutually, make its mutual spliced LED display panel smooth; Exempted multiple working procedures such as punching and blanking, flanging moulding, welding, avoided mismachining tolerance and distortion, casing is easy to make, has improved efficient and output; Spliced LED display panel is smooth, LED lamp array is neat straight, the slit is little between casing, and improvement effect is remarkable.
Description of drawings
Fig. 1 is for provided by the invention a kind of by the structural representation that comprises the LED display unit box that section bar constitutes;
Fig. 2 is a kind of schematic cross-section of middle column section;
Fig. 3 is a kind of schematic cross-section of lateral column section bar.
Embodiment
Specify the present invention below in conjunction with accompanying drawing.
As shown in Figure 1, for provided by the invention a kind of by comprising the LED display unit box that section bar constitutes, this casing is made up of led circuit assembly 1, upper cover plate 2, lower cover 3, two center pillars 4, left side post 5, right side post 6, front panel 7 and rear case components 8.Two center pillars 4, left side post 5 and right side post 6 usefulness screws and upper cover plate 2, lower cover 3 and the front panel 7 fixing box frame that forms of fitting.Fixedly mount led circuit assembly 1 in front on the plate 7, trailing flank fixed installation rear case component 8.Two center pillars 4 are section bar, and there are 3 open loop holes 9 in this section bar cross section as shown in Figure 2, section bar after vertically blocking in open loop hole 9 tapping so that install cover plate 2 and lower cover 3 with screw.Left side post 5 and right side post 6 also are section bar, its cross section as shown in Figure 3,2 open loop holes 9 are arranged respectively on left side post 5 and right side post 6, and tapping in open loop hole 9 is so that install cover plate 2 and lower cover 3 with screw, and its side has with the concavo-convex each other groove 10 of rectangle, rib 11 so that agree with.The groove 10 of lateral column, rib 11 are installed on the both sides of box frame outwardly respectively, so that can agree with mutually about the unit box of installation.
Obviously, the embodiment of the invention has been exempted multiple working procedures such as punching and blanking, flanging moulding, welding; Use section bar, unit box form accuracy and consistency are guaranteed to some extent; The casing side is concavo-convex each other, about can agree with mutually, make its mutual spliced LED display panel smooth.Therefore, the present invention has the outstanding advantage that improvement effect is remarkable, easy to make and efficient is high.
