Through the linkage between the limiting unit 6 and the snap-fit ​​block 7, the fixed part 3 and the supporting part 10 are limited and fixed, ensuring the stability of the fixed part 3 and the supporting part 10 during operation.

[0031] In this embodiment, as Figure 2 and 3As shown, the limiting unit 6 comprises a mounting seat 61, a limiting block 62 is rotatably mounted in the mounting seat 61, a reset spring 64 is fixedly connected to the side of the limiting block 62 close to the clamping block 7, the other end of the reset spring 64 is fixedly connected with the vehicle frame 1, and the side of the limiting block 62 away from the clamping block 7 is fixedly connected with an adjusting plate 63. In use, the limiting block 62 is driven to rotate around the central axis of the mounting seat 61 by pulling the adjusting plate 63, so as to adjust the position of the limiting block 62. After the adjusting plate 63 is released, the limiting block 62 returns to the original position under the action of the reset spring 64.

[0032] In this embodiment, as shown in Figure 2 and 3 , the vertical section of the limiting block 62 is L-shaped, the vertical section of the clamping block 7 is T-shaped, and the limiting block 62 is matched with the clamping block 7. In use, the limiting block 62 can be clamped together with the clamping block 7, that is, the clamping block 7 can be limited and fixed by the limiting block 62.

[0033] In this embodiment, as shown in Figure 1 and 2 , the rear end of the supporting part 10 is provided with a rotating groove 11, and the rotating groove 11 is rotatably connected with a blocking plate 12. The upper surface of the bearing plate 4 is provided with a binding rope 5 on one side of the limiting unit 6. In use, the binding rope 5 is used to bind and fix the aircraft cabin cover placed on the transfer trailer, which is convenient for transportation. The rear end of the aircraft cabin cover is blocked by the blocking plate 12 to prevent the aircraft cabin cover from sliding off the transfer trailer during transfer.

[0034] In this embodiment, as shown in Figure 1 and 4 , the vehicle frame 1 is slidably connected with a pulling rod 17 through a sliding hole 16, the front end of the pulling rod 17 is fixedly connected with a pull ring 18, the outer surface of the pull ring 18 is wrapped with a non-slip rubber sleeve, the rear end of the pulling rod 17 is rotatably connected with a rotating rod 19, the rear end of the rotating rod 19 is fixedly connected with an anti -fall block 20, the inner wall of the vehicle frame 1 is provided with a rectangular groove 21 on one side of the sliding hole 16, and the inner diameter of the rectangular groove 21 is matched with the outer shape of the anti -fall block 20. In use, the pulling rod 17, the rotating rod 19, the anti -fall block 20, the pull ring 18 and the vehicle frame 1 are matched to facilitate the movement of the transfer trailer by the staff.

[0035] In this embodiment, as shown in Figure 2As shown, casters 13 are fixedly installed on the lower surfaces of both bearing plate 1 4 and bearing plate 2 8. There are four casters 13, which are evenly distributed in a linear array below the frame 1.

[0038] Working principle: When using the aircraft canopy transfer trailer of this application, by setting rotating seat 1 2 and rotating seat 2 9, the frame 1 is rotatably connected to the fixed part 3 and the supporting part 10 respectively. When not in use, the fixed part 3 and the supporting part 10 can be folded and stored in the frame 1, thereby saving space, facilitating storage and long-distance transportation, and reducing the cost of relocation transportation. When the fixed part 3 and the supporting part 10 need to be used, the adjusting plate 63 is moved to drive the limiting block 62 to rotate around the central axis of the mounting base 61, so as to adjust the position of the limiting block 62. After the fixed part 3 and the supporting part 10 are rotated to the designated working position, the adjusting plate 63 is released, and the limiting block 62 returns to its original position under the action of the return spring 64, thereby limiting and fixing the snap-fit ​​block 7, so as to limit and fix the fixed part 3 and the supporting part 10, ensuring the stability of the fixed part 3 and the supporting part 10 during operation.
