Description
Technical field
The utility model relates to a kind of rack of sheet metal structural, and especially a kind of architecture advances of sheet metal structural communication cabinet belongs to the radio communication technology field.
Background technology
Understand according to the applicant, the rack that is used for the electronic communication series products in the market mostly is the frame-type splicing structure, and its shortcoming is:
1, rigidity and intensity are relatively poor, and the weight that can carry is little, can not be used for large-scale communication system, and resonance frequency is low, do not possess enough opposing thump abilities.
2, because the splicing slit is many, cause various electromagnetic leakages easily, make Electro Magnetic Compatibility descend greatly, therefore can not be with the rack that is made in working equipment under the complex electromagnetic environment.
3, head tree mostly is the drawing aluminium section bar, and case hardness is low, and is fragile, brings difficulty for the processing of rack, the scrappage height, and aluminium section bar price height makes the rack cost increase in addition.
Summary of the invention
The purpose of this utility model is: at existing like product rigidity and intensity difference, the bad shortcoming of Electro Magnetic Compatibility, design a kind of anti-anti-impact of shaking, the well behaved sheet metal structural communication cabinet of electromagnetic protection.
In order to reach above purpose, sheet metal structural communication cabinet of the present utility model mainly is made of side plate and the upper and lower crossbeam that sheet metal is made.Described side plate two vertical edges are 180 ° of flanging structures of " L " shape, and the upper and lower end of two vertical edges has interspersed mouthful that inserts the crossbeam termination.Described crossbeam forms with the sheet metal bending, and two ends have the embedding notch that inserts 180 ° of flangings of side plate, two side plates with fixedly connected after four upper and lower crossbeams are interspersed, chimeric mutually.
Above design of the present utility model makes the front end face of 180 ° of flanging side plates form the cabinet front column, and the embedding notch design of upper and lower crossbeam makes that the side plate location is very easy.When side plate and upper and lower crossbeam intert mutually, chimeric after, only need short seam part to freeze, just can form rack main body with firm frame structure, thereby the problem on deformation of having avoided slit to freeze and bring.Meanwhile, design of the present utility model also makes rack become continuous electric conductor, has therefore both improved Electro Magnetic Compatibility, has also improved the rack resonance point, and is highly beneficial to improving resistance to shock.
On above basis, the utility model further improves and is, the outer rim of side plate two vertical edges is bent into long radius bending angle, makes the outer facade edge of rack arc transition like this, and the lines flow smoothly, not only handsome in appearance, also increased the fail safe of using.

Embodiment
Embodiment
The flush type sheet metal structural communication cabinet of present embodiment as shown in Figure 1 and Figure 2, the integral body of this rack is the sheet metal structural of sheet metal bending and forming, its main member is left and right side plate 1,2 and the upper and lower crossbeam 3,4 that steel plate is made.The structure of its latus inframedium as shown in Figure 3, two vertical edges are 180 ° of flanging structures of " L " shape, outer rim is bent into long radius bending angle, its front end face has formed the column of cabinet front.The upper and lower end of side plate two vertical edges has interspersed mouthful that inserts upper and lower crossbeam 3,4 terminations.Because front end face adopted the design at long radius bending angle, thereby make the outer facade edge of rack arc transition, not only the lines flow smoothly, handsome in appearance, also increased the fail safe of using.
Upper and lower crossbeam 3,4 all forms with the steel plate bending, and integral body is that " [" shape, two ends are made the interspersed head of bending, and have the embedding notch a (referring to Fig. 4) that inserts 180 ° of flangings of side plate.1,2 and four upper and lower crossbeams 3,4 of two side plates all select for use the thick steel plate of 1~1.5mm to make, after interspersed, chimeric mutually, be connected by local piece welding, make it to become the very high rigid body framework of intensity, mix again after top cover 7, bottom 10, bonnet 8 and the reinforcement 9, promptly constituted the rack main body.
Above structural design has improved the resonance frequency of rack, has strengthened the ability of anti-vibrating and impact greatly, has avoided the ubiquitous seam of available frame formula structure to form the defective that gap leakage causes electromagnet shield effect to descend too much, easily.
In addition, present embodiment also has following design feature:
1, in order to make rack have bigger bearing capacity, present embodiment also designs four inner columns 5 that steel plate bends, and its cross section is the notch channel steel shape of flanging (referring to Fig. 5) in the same way.During assembling, four inner columns 5 are inserted in respectively in four jiaos of left and right side plate 1,2, to play booster action.On inner column 5, have many group standard installation holes, thereby different accessories can be installed as required, as walk line bracket, part cartridge, unit blower fan etc.
2, in order to guarantee that this rack becomes the standard universal rack in large scale system, can push the height dimension system arbitrarily is the international standard extension unit of U=44.45mm, present embodiment is installed column 6 before also having designed " " shape that is connected with inner column 5, have many groups standard U series installing hole on it, and be furnished with unsteady swivel nut, in order to the extension unit panel screw to be installed.Therefore extension unit can combination in any, exchange, install very convenient.
3, convenient for the rack lifting that makes the big load of carrying, present embodiment is provided with the reinforcement cushion block on eight drift angles of rack, fixing lifting bolt on the reinforcement cushion block at top.In addition, the vibration isolator of can packing in the bottom as required.
4, for guarantee rack can be big in difference variation, work under the high maritime condition of high humidity, salt fog concentration, during design selecting for use with the process for protecting of material surface of construction material done careful consideration, the member surfaces externally and internally all adopts special galvanized passivation process, the compound enamelled coating of outer surface spraying " three is anti-" (damp proof, mildew-resistant, anti-salt fog) better performances.
The rack rigidity height, the intensity that experiment showed, present embodiment are good, have the shock-resistant ability of higher antivibration; By the design that helps electromagnetic protection, improved the electromagnet shield effect of rack; Take effectively " three is anti-" technological measure, improved the corrosion resistance of rack, guaranteed the reliable and stable of long-term use.This rack is by various environmental tests, reliability test etc.Wherein, the high impact shock test index is that general rack is unapproachable.In addition, this rack has also that parts are few, versatility is high, processing technology is good, low cost of manufacture, outstanding advantage such as is convenient to install, safe in utilization.
In addition to the implementation, the utility model can also have other execution modes.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection range of the utility model requirement.
