Description

Technical Field

[0001] The utility model relates to aircraft lifesaving, in particular to a flexible transfer assembly for realizing the rapid connection and separation of a slide and a cabin door. Background Art

[0002] The emergency evacuation slide is an important life-saving facility on civil aircraft. It is mainly used to help passengers and crew members evacuate quickly and safely from the aircraft in an emergency. When in use, the emergency evacuation slide is either installed at the aircraft door or at the wing. For the emergency evacuation slide installed at the aircraft door, the emergency evacuation slide and the aircraft door are indirectly connected using an adapter. One end of the adapter is completely fixed to the emergency evacuation slide, and the other end is placed on the cross brace of the aircraft door. An external limit assembly is added to prevent movement along the cross brace. The current adapter has the following problems: 1) When performing regular inspection and maintenance on the emergency evacuation slide, the external limit assembly must be removed first before the adapter can be pulled out, and then the emergency evacuation slide can be removed for inspection. After inspection, the above process must be reversed to complete the reset and installation. , which is very troublesome; 2) When inspecting the emergency evacuation slide, the adapter is completely fixed to the emergency evacuation slide and cannot be separated from the emergency evacuation slide. There will be some areas of the emergency evacuation slide that are blocked and cannot be inspected, which poses a risk; 3) When the aircraft is forced to land on the water, after the emergency evacuation slide is deployed and the aircraft is in danger of sinking, it is necessary to operate on the emergency evacuation slide (not at the aircraft door) to separate the emergency evacuation slide from the aircraft. Since the adapter is completely fixed to the emergency evacuation slide, it can only be separated by cutting, and the emergency evacuation slide cannot be quickly separated. Utility Model Content

Figure 1 The end of the slide separation handle 19 is provided with a front separation latch 17 and a back separation latch 18. The front separation latch 17 cooperates with the front connecting lace 15 during installation to lock the front connecting lace 15 with the corresponding front connecting hole 21. After the front connecting lace 15 is withdrawn, it returns to a free state. The back separation latch 18 cooperates with the back connecting lace 13 during installation to lock the back connecting lace 13 with the corresponding back connecting hole. After the back connecting lace 13 is withdrawn, it returns to a free state. Figure 1 The matching mode of each pin and the corresponding lace is determined according to the specific threading and winding mode of the corresponding lace. The pin can be passed through each corresponding lace in sequence, or the corresponding laces can be connected to each other in sequence, and then the pin can be passed through the last lace.
