[0043] The frame bottom plate 103 , the frame back plate 104 and the frame top curved plate 105 together form a frame structure. A fine-tuning component 108 is assembled in the frame structure, and the strip-shaped gap 111 extends from the top of the fine-tuning component 108 .

[0044] The flexibility and stability of hatch door processing are improved through the coordinated design of the support base, hydraulic telescopic rod, frame structure and fine-tuning components.

[0045] like Figures 1 to 8 As shown, in this embodiment, the inner wall surface of the frame back plate 104 is respectively provided with an arc-shaped fixed block 106, an arc-shaped movable block 107 and an arc-shaped baffle 109 from top to bottom. The arc-shaped fixed block 106 is provided with a first groove 112, and the arc-shaped movable block 107 is provided with a second groove 113;

[0046] A guide groove 116 is formed on the side wall of the frame back plate 104. At least two sliders are provided at the bottom of the arc-shaped movable block 107. A limit block 118 is provided at the bottom of the slider. The slider is located in the guide groove 116. The limit block 118 is slidably attached to the outer wall of the frame back plate 104.

[0047] The arc-shaped fixed block 106 and the arc-shaped movable block 107 fit together to form a common contact surface, and the first groove 112 cooperates with the common contact surface to form a first assembly groove; when the first groove 112 is connected to the second groove 113, the second groove 113 cooperates with the common contact surface to form a second assembly groove;

[0048] The fine-tuning assembly 108 includes a limit block 118, a suction cup 119, a pull rod 120, a fixed seat 121, a movable guide block 122 and a hollow tube 124. The movable guide block 122 can be sleeved in the first assembly groove or the second assembly groove. A fixed seat 121 is provided on the top of the movable guide block 122. A threaded channel is opened on the fixed seat 121. The central axis of the threaded channel is perpendicular to the arc surface of the arc panel 105 at the top of the frame. A hollow tube 124 is threadedly connected in the threaded channel. The hollow tube 124 is a through hollow structure. A suction cup 119 is provided on the top of the hollow tube 124, and a conducting hole connected to the hollow structure is opened at the center position of the suction cup 119, a limiting block 118 is provided on the bottom outer wall surface of the hollow tube 124, and a leather pad is provided on the sliding sleeve inside the hollow structure of the hollow tube 124. The bottom of the leather pad is fixedly connected to a connecting rod, and the connecting rod extends out of the bottom of the hollow structure and is fixedly connected to a pull rod 120; wherein, the strip gap 111 extends from the top of the hollow tube 124, and the suction cup 119 is located above the arc panel 105 at the top of the frame.

[0049] Through the coordinated design of the first assembly groove, the second assembly groove and the fine-tuning component, the adjustment of the fine-tuning component is made more flexible, thereby improving the flexibility of hatch processing.

[0050] like Figure 1 、 Figure 2 and Figure 8 As shown, in this embodiment, the distance between the left and right side walls of the movable guide block 122 (the left and right sides of the movable guide block 122 refer to the left and right sides of the frame back plate 104) is greater than the distance between the upper and lower side walls of the movable guide block 122 (the upper and lower sides of the movable guide block 122 refer to the upper and lower sides of the frame back plate 104).

[0051] By designing that the distance between the left and right side walls of the movable guide block 122 is greater than the distance between the upper and lower side walls of the movable guide block 122, it is ensured that the movable guide block 122 can slide and switch more stably between the first assembly groove and the second assembly groove, thereby allowing the fine-tuning component to slide and switch between the first assembly groove and the second assembly groove.

[0052] like Figure 3 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown, in this embodiment, the top edges of the first groove 112 and the second groove 113 are both provided with a limiting fold 117, and a stepped edge 123 is provided between the fixed seat 121 and the movable guide block 122, and the limiting fold 117 and the stepped edge 123 match each other.

[0053] The matching design of the limiting fold 117 and the stepped edge 123 restricts the movable guide block 122 from sliding out of the first assembly groove or the second assembly groove.

[0054] like Figure 1 and Figure 2 As shown, in this embodiment, the upper surface of the arc baffle 109 is in an arc shape, and an arc magnet 110 is provided on the upper surface of the arc baffle 109 , and a magnet sheet that cooperates with the arc magnet 110 is provided at the bottom of the pull rod 120 .

[0055] The arc-shaped magnet 110 is designed to cooperate with the magnet sheet to temporarily fix the pull rod 120, thereby ensuring that the suction cup 119 of the aviation cabin door is in a negative pressure state.

[0056] like Figures 1 to 7 As shown, in this embodiment, the outer side walls of the frame back plate 104 on the left and right sides are respectively provided with a first elastic latch 114 and a second elastic latch 115, and the first elastic latch 114 and the second elastic latch 115 are both located below the guide groove 116;

[0057] When the arc-shaped fixed block 106 and the arc-shaped movable block 107 are in a vertically aligned state to form a first assembly groove, the first elastic latch 114 is inserted into the locking hole provided on the left limit block 118;

[0058] When the arc-shaped fixed block 106 and the arc-shaped movable block 107 are in a vertically dislocated state to form a second assembly groove, the second elastic latch 115 is inserted into the locking hole provided on the right limiting block 118 .

[0059] The state between the arc-shaped fixed block 106 and the arc-shaped movable block 107 corresponds to the switching between the first elastic latch 114 and the second elastic latch 115 , thereby ensuring that the arc-shaped fixed block 106 and the arc-shaped movable block 107 are fixed after sliding relative to each other.

[0060] Working principle:

[0061] First, an arc-shaped surface is provided at the top of the arc panel 105 at the top of the frame, and a soft rubber strip is provided at the top of the arc-shaped surface, which can match the shape of the aircraft cabin door and facilitate the processing of the aircraft cabin door. After the aircraft cabin door is stably placed, the pull rods 120 are pulled one by one, so that the magnet sheet on the pull rod 120 is magnetically attached to the arc magnet 110 on the arc baffle 109 to form a temporary fixation, thereby generating an outward suction force inside the hollow tube 124, thereby ensuring that the suction cup 119 is deformed and tightly attached to and fixed to the outer wall of the cabin door, and the inside of the hollow tube 124 is in a negative pressure state, which can better ensure the limiting support of the aircraft cabin door and will not cause major damage to the surface of the aircraft cabin door.

[0062] When the position of the fine-tuning component 108 on the aircraft cabin door needs to be adjusted, the first elastic latch 114 is opened (the suction cup 119 in this state is not attached to and fixed to the aircraft cabin door), so that the arc-shaped movable block 107 moves in the guide groove 116 until the first groove 112 is connected to the second groove 113. At this time, the second elastic latch 115 locks the limit block 118 on the corresponding side, and the movable guide block 122 moves downward, so that the movable guide block 122 enters the second assembly groove formed by the second groove 113 and the common contact surface. The need to adjust the position on the aircraft cabin door causes the movable guide block 122 to slide in the second assembly groove, thereby changing the contact position of the suction cup 119 with the aircraft cabin door, thereby adjusting the position of the fine-tuning component 108 on the aircraft cabin door. After the position adjustment is completed, the pull rod 120 is pulled so that the magnet sheet on the pull rod 120 is magnetically attached to the arc-shaped magnet 110 on the arc-shaped baffle 109 to form a temporary fixation, thereby generating an outward suction force inside the hollow tube 124, causing the suction cup 119 to deform and fit tightly and be fixed to the outer wall of the cabin door.

[0063] The steps of adjusting the fine-tuning component 108 are to rotate the limit block 118 so that the threaded connection between the fixing seat 121 and the hollow tube 124 is activated, so that the suction cup 119 and the hollow tube 124 are close to the aircraft cabin door, and the suction cup 119 is attached to the aircraft cabin door. Stop rotating the limit block 118, and then pull the pull rod 120 so that the suction cup 119 is not only attached to the aircraft cabin door, but also in a state of being sucked and fixed to each other. Although the distance between the pull rod 120 and the arc magnet 110 is different, it can be compensated by the connecting rod connected to the pull rod 120, that is, when the distance between the pull rod 120 and the arc magnet 110 is longer, a part of the connecting rod is pulled out more, and when the distance between the pull rod 120 and the arc magnet 110 is shorter, a part of the connecting rod is pulled out less. The length of the connecting rod is ensured by making the negative pressure generated at the suction cup 119 different. The negative pressure generated at the suction cup 119 can ensure that the suction cup 119 is in contact with the aircraft cabin door and is in a sucked and fixed state.

[0064] Of course, the arc baffle 109 and the arc magnet 110 can also be divided into multiple parts (each part includes a section of arc baffle 109 and a section of arc magnet 110, and the length of each section is determined according to actual conditions), each part corresponds to a fine-tuning component 108, and each arc baffle 109 can also be slidably connected and locked with the frame back plate 104 (the sliding connection and locking method can adopt existing mature technology), so as to ensure that the distance between the pull rod 120 and the arc magnet 110 is moderate by adjusting the distance between the arc baffle 109 and the pull rod 120.

[0065] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
