Description
Technical field
Aviation antidetonation shielding case equipment technical field is the utility model is related to, is used for aviation more particularly to one kind
Protecting against shock vibrates the closing beam structure of shielding case.
Background technology
Air environment is the important component of aircraft, in use often by aircraft engine sheet
Body, the pneumatic flow-disturbing of aircraft exterior, vibration, the percussion of the flight attitude of aircraft and the factor such as take off, land, sliding
Power.If the anti-vibration ability of equipment itself, in use will because of above-mentioned vibration, percussion and produce therefore
Barrier, so as to influence the performance of whole aircraft.Under normal circumstances, equipment, which breaks down, mainly following two situations, one kind be
Resonated on some Frequency point, and make the amplitude of equipment increasing, finally destroyed more than the limit acceleration of equipment.One
Although kind be vibration, impact acceleration not less than the limit acceleration that equipment is born, due to Long-term Vibration, and make equipment because
Fatigue and destroy.Carrier of the cabinet as electronic equipment, it appears it is particularly important, in order to ensure machine generation in the reliable of electronic equipment
Property, cabinet has to carry out anti-vibration protecting against shock design.The vibration environment condition of air environment work is severe, and cabinet is
Its main carriers, it is therefore desirable to reinforced in structure to cabinet, while its anti-vibration is improved using shock insulation buffer system
Ability, so as to improve the reliability of whole air environment and service life.
In the aviation antidetonation shielding case of prior art, its structure type generally use crossbeam, cover plate and side plate etc.
Part frame forms, and this structure type is simple and practical, but stability is relatively poor, the crossbeam especially used at present, uses
Open aluminum alloy plate materials shearing is made.And aviation antidetonation shielding case interior instrument it is more, it is necessary to connection
Position is also relatively more, when needing to connect other components, drills, welds typically directly on crossbeam, easily influences crossbeam
Mechanical property, weaken the impact resistance of whole aviation antidetonation shielding case.
Utility model content
The purpose of this utility model is：In order to solve the aviation antidetonation shielding case beam part connection position of prior art
Shortage is put, it is necessary to connect miscellaneous part using modes such as drillings, easily influences the mechanical property of crossbeam, weakens the anti-of whole cabinet
The problem of impact capacity, the utility model provide a kind of closing beam structure for aviation protecting against shock vibration shielding case.
The utility model specifically uses following technical scheme to achieve these goals：
A kind of closing beam structure for aviation protecting against shock vibration shielding case, including main body of cross-beam, the crossbeam master
Body is provided at both ends with seam locating slot, be further opened with main body of cross-beam for steel-wire screw-socket is installed circular bottom outlet, for pacifying
Drive the rivets and connect the flat hole of block, for installing the irregularly-shaped hole of nut strip, the special-shaped hole site is in the inner side of main body of cross-beam.
Preferably, the irregularly-shaped hole includes rectangular portion and curved portions, the rectangular portion is located at the inner side of main body of cross-beam.
Preferably, the rectangular portion to the distance of the inner side edge of main body of cross-beam be 5mm-6mm.
Preferably, the main body of cross-beam is formed by six line aluminium alloy one extrusion forming processing and fabricatings.
Preferably, the both ends of the circular bottom outlet are also arranged with the nut for coordinating with steel-wire screw-socket.
The beneficial effects of the utility model are as follows：
1. because aviation antidetonation shielding case internals is more, it is necessary to connect a variety of parts in casing, and
The cabinet of prior art be generally all using directly on the crossbeam of sheet perforate miscellaneous part is installed, because crossbeam is as machine
The main bearing member of case, the crossbeam of the sheet of prior art is because slenderness ratio is larger, and in airborne vibration, crossbeam rocks width
Spend larger, perforate is more on crossbeam easily influences its mechanical property, so that cabinet stability reduces, safety is buried for flight
Hidden danger；Closed beam structure of the present utility model, the connector commonly used in cabinet is integrated into inside main body of cross-beam, is ensured horizontal
The continuity on the both sides up and down of beam main body, so as to ensure its integral rigidity, the mechanical property of design is maintained, when needs are in horizontal stroke
When miscellaneous part is connected on beam, installed using reserved various mounting holes, without entering to the main stress area of crossbeam
Row bore operation, the bulk strength of crossbeam is ensured, improved the job stability of aviation antidetonation shielding case.
2. box house electronic component is numerous, its caused electromagnetic interference is more, and space shuttle is in flight course
Need to mask this unnecessary interference, traditional beam-end needs to connect substantial amounts of grounding copper winding displacement, could be effective
By EMI blockage in box house, and vibration can be also followed in aircraft vehicle vibrations, between grounding copper bar, easily released,
Electromagnetic interference is caused to reveal；The utility model devises seam locating slot in beam-end, mutual using male half coupling and concave mouth
Coordinate clamping, without unnecessary connector, the junction of beam-end just can be made more stable, it is not easy to depart from vibration, protect
The continuity of electric current is held, so as to effectively shield electromagnetic interference, grounding copper winding displacement has been saved, has improved the work of aviation antidetonation shielding case
Make stability.
3. nut strip is the conventional connector of aviation shielding case, various components are shielded by nut strip installed in aviation
In cabinet；Nut strip is arranged in the irregularly-shaped hole on the inside of main body of cross-beam by the utility model, when needing to connect component, is passed through
Tapping drilling installation, when tapping drills, irregularly-shaped hole is not easily controlled with the spacing on the inside of main body of cross-beam, and spacing is excessive,
Then it is not easy to drill through, spacing is too small, influences structural strength again；Rectangular portion of the present utility model is to the inner side edge of main body of cross-beam
Distance is 5mm-6mm, and this value range is applied to most of aviation thread-cutting screw, can drilled through easily, and do not influence structure
Intensity, at the same time, when connecting some widgets, without being connected with nut strip, only it need to pass through self-tapping screw in this region
Installation, a kind of two kinds of purposes of structure are realized, make cabinet use more flexible and efficient.
4. main body of cross-beam of the present utility model is formed by six line aluminium alloy one extrusion forming processing and fabricatings, squeezed using one
The molded structure for making main body of cross-beam is more stablized, and mechanical property is more outstanding, improves the impact resistance of equipment.
