[0034] An aircraft canopy support rod fastening structure, such as Figure 1 As shown, it includes a load-bearing block 1, a bolt 2, and a nut 3.

[0035] The load-bearing block 1 is hinged at one end of the support rod 4, and can be specifically hinged by a single-ear and double-ear structure with a pin. There is a strip through hole on the load-bearing block 1. The load-bearing block 1 is made of metal with good salt spray resistance, light weight and wear resistance.

[0036] The other end of the support rod 4 is hinged on the cockpit cover, and the cockpit cover is installed on the cockpit load-bearing frame 5. The cockpit load-bearing frame 5 is provided with a strip-shaped installation hole.

[0037] The bolt 2 is provided through the strip-shaped through hole, and the head is rectangular. The top of the bolt 2 has an anti-rotation groove, which is in a straight line shape. The bolt 2 is made of metal with good salt spray resistance, light weight, and wear resistance, such as Figure 2 shown.

[0038] Nut 3 is a butterfly nut, which is screwed onto bolt 2. Nut 3 is made of metal with good salt spray resistance, light weight and wear resistance, such as Figure 3 shown.

[0039] The rectangular head of the adjustment bolt 2 is parallel to the strip mounting hole on the cabin bearing frame 5 and can pass through the strip mounting hole. The rectangular head of the adjustment bolt 2 is perpendicular to the strip mounting hole on the cabin bearing frame 5. Tightening the nut 3 can fasten the bearing block 1 to the cabin bearing frame 5, thereby fastening the support rod 4 and supporting the cockpit cover in the open position, such as Figure 4 shown.

[0040] When tightening the nut 3, a wrench can be inserted into the anti-rotation groove to prevent the bolt 2 from rotating, so that the rectangular head is parallel to the strip mounting hole on the cabin load-bearing frame 5 and then escapes from the strip mounting hole.

[0041] The aircraft cockpit cover support rod fastening structure disclosed in the above embodiment has a simple overall structure, and is small in weight and volume, and can ensure reliable fastening of the support rod 4. Moreover, the fastening of the support rod 4 is achieved only by adjusting the parallelism and verticality of the rectangular head of the bolt 2 and the strip mounting hole on the cockpit load-bearing frame 5, and tightening the nut 3 and other simple operations. The operation is simple and convenient. In addition, when the nut 3 is loose, the clearance between the strip through hole on the load-bearing block 1 and the bolt 2 can be utilized to slide the load-bearing block 1, so as to adjust the fastening state of the support rod 4 and the opening position of the cockpit cover, and the structure has a certain adjustment function.

[0042] A method for fastening a support rod of an aircraft canopy is implemented based on the aircraft canopy support rod fastening structure disclosed in the above embodiment, comprising:

[0043] Adjust the rectangular head of the bolt 2 to be parallel to the strip-shaped mounting hole on the cabin bearing frame 5, and pass the entire rectangular head of the bolt 2 through the strip-shaped mounting hole on the cabin bearing frame 5;

[0044] Adjust the rectangular head of the adjusting bolt 2 to be perpendicular to the strip-shaped mounting hole on the cabin bearing frame 5;

[0045] Insert a wrench into the anti-rotation groove, tighten the nut 3, and fasten the load-bearing block 1 to the cabin load-bearing frame 5.
