As one of optimal way of the present invention, described Left-Hand Panel is concordant with front panel with the end of the crossbeam of the front end of right panel.
As one of optimal way of the present invention, described front panel is provided with handle.
As one of optimal way of the present invention, described front panel is provided with the hold-down screw connecting rack.
As one of optimal way of the present invention, described hold-down screw is captive screw.
As one of optimal way of the present invention, described reinforcing center is stainless steel metal frame.
As one of optimal way of the present invention, between described metallic shield net and crossbeam, be provided with metallic shield bar.
As one of optimal way of the present invention, the cross section of described metallic shield bar is band bow-shaped structural jaggy.
As one of optimal way of the present invention, described arched metallic shield bar comprises in order to the support cambered surface of supporting traverse and the supporting plane in order to support metal gauze screen, and described breach is positioned at the junction of described support cambered surface and supporting plane.
The utility model has the following advantages compared to existing technology: the utility model is not when changing current Universal machine cabinet general structure, by using metal reinforcing center, structural strengthening is carried out to cabinet, by using metallic shield bar to improve cabinet capability of electromagnetic shielding, and the potential risk that design eliminates scuffing personnel is optimized to front beam.There is the advantages such as compact, shock resistance extruding firm in structure, anti-electromagnetic shielding.

Embodiment
Below embodiment of the present utility model is elaborated; the present embodiment is implemented under premised on technical solutions of the utility model; give detailed execution mode and concrete operating process, but protection range of the present utility model is not limited to following embodiment.
As shown in figs. 1 to 6, the present embodiment comprises machine case body, reinforce center 4 and multiple metallic shield net 8, the machine case body of the present embodiment comprises Left-Hand Panel 1, right panel 5, two front panels 2 and four crossbeams 3, Left-Hand Panel 1 is connected for frame structure with right panel 5 respectively by crossbeam 3, two crossbeams 3 at Left-Hand Panel 1 and right panel 5 top corresponding with it form upper shed structure, two crossbeams 3 of Left-Hand Panel 1 and right panel 5 bottom corresponding with it form under shed structure, metallic shield net 8 is separately positioned in upper shed structure and under shed structure, reinforce center 4 successively by attachment screw and Left-Hand Panel 1, be positioned at the metallic shield net 8 of upper shed structure, right panel 5, the metallic shield net 8 being positioned under shed structure connects, front panel 2 is arranged at the front end of Left-Hand Panel 1 and right panel 5 respectively by attachment screw.
Left-Hand Panel 1 is concordant with front panel 2 with the end of the crossbeam 3 of the front end of right panel 5.The potential risk that the front beam 3 couples of operating personnel eliminating current general extension case may scratch.
Conveniently extracted out from rack by cabinet, front panel 2 is provided with handle 6.
Front panel 2 is provided with the hold-down screw 7 connecting rack.Hold-down screw 7 is captive screw.
The reinforcing center 4 of the present embodiment is stainless steel metal frame.Reinforce the middle part that center 4 can be arranged at machine case body, also can be arranged at the more position of printed circuit board.Can the overall shock resistance extrusion performance improving cabinet after cabinet installs additional, particularly effectively can prevent distortion and the damage of the printing backboard be easily hit.Make casing structure firmer, ensure under long-distance transport and the motor-driven situation of equipment indeformable, and have the anti-extrusion performance of certain shock resistance.
