Embodiment 1

[0030] Such as figure 1 As shown, the present embodiment provides a high-strength aviation anti-shock and anti-seismic shielding cabinet, including two side panels 1 and a rectangular frame 2 parallel to each other, and the rectangular frame 2 is installed between the side panels 1 in parallel; the rectangular frame 2 includes closed beams 3 and reinforced vertical beams 4, the closed beams 3 and reinforced vertical beams 4 are connected by riveting blocks 5 to form a rectangular frame 2; a box includes two sets of rectangular frames 2, and each set of rectangular frames 2 includes two closed Crossbeam 3 and two reinforcing vertical beams 4.

[0031] In order to explain the structure of this embodiment more clearly, the closed beam 3 of this embodiment includes a beam main body 31, and the beam main body 31 is provided with a circular bottom hole 32 for installing a wire screw sleeve and a flat hole for installing a riveting block 5 33 , a special-shaped hole 34 for installin...

Embodiment 2

[0034] This embodiment has made the following optimizations on the basis of Embodiment 1: the two ends of the beam main body 31 in this embodiment are provided with notch positioning grooves 35 for shielding electromagnetic interference, and the notch positioning grooves 35 are divided into convex and concave The mouth uses the form of staggered teeth to strengthen the shielding effect of the edge.

[0035] The working principle of this embodiment is as follows: there are many electronic components inside the box, which generate more electromagnetic interference, and the aircraft needs to shield this unnecessary interference during flight, and the end of the traditional beam needs to be connected to a large number of The grounding copper busbars can effectively seal the electromagnetic interference inside the box, and when the aircraft vibrates, the grounding copper busbars will also vibrate along with it, which is easy to loosen and cause electromagnetic interference leakage; ...

Embodiment 3

[0037] In this embodiment, the following optimizations are made on the basis of Embodiment 1: the special-shaped hole 34 in this embodiment includes a rectangular portion 341 and an arc portion 342, the rectangular portion 341 is located inside the beam main body 31, and the rectangular portion 341 to The distance between the inner sides of the beam main body 31 is most preferably 5mm, and can also be any value between 5mm-6mm.

[0038] The working principle of this embodiment is as follows: the nut strip 6 is a commonly used connector for the aviation shielding cabinet, and various components are installed in the aviation shielding cabinet through the nut strip 6; In the hole 34, when it is necessary to connect components, it can be installed by tapping and drilling. When tapping and drilling, the distance between the special-shaped hole 34 and the inner side of the beam main body 31 is not easy to control. If the distance is too large, it is not easy to drill through. , the ...

Abstract

The invention discloses a high-strength aviation impact-resistant anti-vibration shielding cabinet, and relates to the technical field of aviation shielding cabinet equipment. The cabinet comprises two parallel side plates (1) and a rectangular frame (2), and the rectangular frame (2) is installed between the two parallel side plates (1) in a parallel manner. The rectangular frame (2) comprises a sealing cross beam (3) and a reinforcing vertical beam (4), which are connected through a riveting block to form the rectangular frame (2). The sealing cross beam (3) comprises a cross beam main body (31), and the cross beam main body (31) is provided with a circular bottom hole (32) for installing a steel wire thread sleeve, a flat hole (33) for installing a riveting block (5), a irregularly-shaped hole (34) for installing a nut bar (6), wherein the irregularly-shaped hole (34) is located at an inner side of the cross beam main body (31). The cabinet is advantageous in that the cabinet guarantees the overall strength of the cross beam main body (3) and the reinforcing vertical beam, and improves the work stability.

Description

technical field [0001] The invention relates to the technical field of aviation shielding cabinet equipment, and more particularly relates to a high-strength aviation shockproof and shockproof shielding cabinet. Background technique [0002] Airborne electronic equipment is an important part of the aircraft. During use, it is often subjected to vibration and impact forces from the aircraft engine itself, the aerodynamic turbulence outside the aircraft, the flight attitude of the aircraft, and factors such as takeoff, landing, and taxiing. If the anti-vibration ability of the equipment itself is poor, it will fail due to the above-mentioned vibration and impact during use, thereby affecting the performance of the entire aircraft. Usually, there are two main reasons for equipment failure. One is that resonance occurs at a certain frequency point, which makes the amplitude of the equipment larger and larger, and finally exceeds the limit acceleration of the equipment and is des...
