Example Embodiment

[0029] Example 1

[0030] Such as figure 1 As shown, this embodiment provides a high-strength aerospace shock-proof and seismic shielding case, which includes two parallel side panels 1 and a rectangular frame 2, the rectangular frame 2 being installed in parallel between the side panels 1; the rectangular frame 2 includes a closed cross beam 3 and a reinforced vertical beam 4, the closed cross beam 3 and the reinforced vertical beam 4 are connected by a riveting block 5 to form a rectangular frame 2; a box body includes two groups of rectangular frames 2, and each group of rectangular frames 2 includes two closed frames Cross beam 3 and two reinforced vertical beams 4.

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

Example Embodiment

[0033] Example 2

[0034] This embodiment has made the following optimizations on the basis of Embodiment 1: The two ends of the beam main body 31 of this embodiment are provided with a stop positioning groove 35 for shielding electromagnetic interference, and the stop positioning groove 35 is divided into a convex stop and a concave stop. The mouth is used in the form of canine 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 aviation aircraft needs to shield this unnecessary interference during the flight, and the end of the traditional beam needs to be connected to a large number of The grounded copper wire can effectively seal the electromagnetic interference inside the box. When the aircraft vibrates, the grounded copper bars will follow the vibration, which is easy to loosen and cause electromagnet...

Example Embodiment

[0036] Example 3

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

[0038] The working principle of this embodiment is as follows: the nut bar 6 is a commonly used connector for aviation shielding cabinets, and various components are installed in the aviation shielding cabinet through the nut bar 6; the box body installs the nut bar 6 on the profile inside the beam main body 31 In the hole 34, when the components need to be connected, 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 body 31 is not easy to cont...

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...
