Abstract

The utility model relates to the technical field of LED display screen, especially to a novel LED display screen cabinet section bar structure which comprises a surface shield, an LED lamp sheet and a bottom casing, and is characterized in that a power supply system box electrically connected with the LED lamp sheet is arranged on the center of the bottom casing, heat radiation areas for the system to radiate heat are arranged at both sides of the power supply system box, and locking bar insertion holes for splicing the cabinet and locking bar connecting pins matching and connecting with the locking bar insertion holes are arranged on side surfaces of the four corners of the bottom casing. With large radiating areas, the system is excellent in heat radiation performance. With the cooperative connection between the locking bar connecting pins and locking bar insertion holes, the splicing of cabinet is simpler and more convenient. The assembly accuracy is improved greatly. The bottom casing has bound edge section bars and reinforcement angle aluminums, which makes the splicing of the cabinet and the cabinet itself more solid. Furthermore, positioning pin and positioning structure further improve the assembly accuracy, and effectively shorten installation time. The novel LED display screen cabinet section bar structure is highly practical.

Description

A kind of Novel LED display screen box profile structure

Technical field

The utility model relates to the LED display technical field, especially a kind of Novel LED display screen box profile structure.

Technical background

Known, the range of application of LED display technology is more and more wider; General LED display all is the iron casing, adopts the panel beating bending to be welded, and its processed complex, precision are not high, casing is firm not, very loaded down with trivial details, to be improved when module and assembly unit are installed.

The utility model content

The purpose of this utility model provides firmly Novel LED display screen box profile structure of a kind of easy and simple to handle, compact conformation.

To achieve these goals, the utility model adopts following technical scheme:

A kind of Novel LED display screen box profile structure, it comprises face shield, LED lamp sheet and drain pan, and described face shield is fixedly connected on the front of drain pan, and described LED lamp sheet is positioned in the middle of face shield and the drain pan, and the back side of described drain pan is provided with:

The power-supply system box that is positioned at drain pan central authorities, is electrically connected with LED lamp sheet;

Be symmetrically distributed in the radiating area of power-supply system box both sides;

Be opened in the locking bar pin hole on the side, four corners of drain pan;

And the locking bar connecting pin that is connected with the locking bar pin hole.

Preferably, four of described drain pan edges also are provided with the reinforcement aluminum corner brace.

Preferably, the side all around of described drain pan is Edge-protecting section bar.

Preferably, the top side face of described drain pan is provided with register pin.

Preferably, the top of described face shield and drain pan junction is provided with the positioning convex structure, the bottom is provided with the detent structure.

Owing to adopted such scheme, the utility model provides good radiating condition by the large tracts of land radiating area that arranges for system, and the compounding practice by locking bar pin hole and locking bar connecting pin is so that the splicing of casing is more simple and convenient, splicing accuracy significantly improves; Simultaneously, utilize the drain pan of Edge-protecting section bar and reinforcement aluminum corner brace so that box body splicing and casing itself is more firm; In addition, also further improve splicing accuracy by register pin and the location structure that arranges, effectively shortened the set-up time, had very strong practicality.

Embodiment

As illustrated in fig. 1 and 2, a kind of Novel LED display screen box profile structure of present embodiment, it comprises face shield 1, LED lamp sheet 2 and drain pan 3, and face shield 1 is fixedly connected on the front of drain pan 3, and LED lamp sheet 2 is positioned in the middle of face shield 1 and the drain pan 3, and the back side of drain pan 3 is provided with:

Power-supply system box 4: be positioned at the central authorities of drain pan 3, be electrically connected with LED lamp sheet 2, be the control center of whole LED display;

Radiating area 5: be symmetrically distributed in the both sides of power-supply system box 4, for whole LED display provides good radiating condition;

Locking bar pin hole 6: be opened on the side, four corners of drain pan 3, for guaranteeing the casing splicing effect, on drain pan 3, offered altogether 8;

Locking bar connecting pin 7: be connected with locking bar pin hole 7, for avoiding each casing the redundancy of locking bar connecting pin 7 to occur when the assembly unit, thereby cause waste of material, be provided with altogether 4 on each drain pan, just can guarantee to greatest extent when a plurality of box body splicing the total docking of locking bar pin hole 6 with this.

Shown in Fig. 3 and 4, firm for the intensity of strengthening casing self and each box body splicing, four edges of drain pan 3 are provided with strengthens aluminum corner brace 8, Edge-protecting section bar 9 is adopted in the side around the drain pan 3, the integral body of wherein strengthening aluminum corner brace 8 is subtriangular, adopts the M10 tapping, and the degree of depth is 30 ± 1.0mm.

Simultaneously, for improving the precision of assembly unit, top side face at drain pan 3 is provided with register pin 10, top in face shield 1 and drain pan 3 junctions is provided with positioning convex structure 11, the bottom is provided with detent structure 12, thus, when box body splicing, just can be according to the contraposition of positioning convex structure 11 and detent structure 12, realize fast the location, reduce assembling duration, improved work efficiency.

In addition, for ease of carrying, dismounting or casing is installed, be provided with handle 13 at the middle part of the left and right side of power-supply system box 4.

The above only is preferred embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model instructions and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
