When the rear support frame 300 rotates upright around the second hinge axis relative to the upper frame rear body 101, the rear The fourth positioning pin holes 35 of each rear support rod 31 of the support frame 300 just correspond to the third positioning pin holes 1121 of the corresponding rear ear plates 112 in the rear frame body 101 of the upper frame. At this time, a second locking pin 34 is inserted into each pair of corresponding third positioning pin holes 1121 and fourth positioning pin holes 35, so that the rear support frame 300 remains upright relative to the rear frame body 101 of the upper frame. When it is necessary to unlock the rear support frame 300 so that the rear support frame 300 can be folded and retracted into the rear frame body 101 of the upper frame, it is only necessary to pull out each second locking pin 34 from the first positioning pin hole 6121 of the corresponding rear ear plate 112. At this time, the rear support frame 300 can be flipped and folded around the second hinge axis again to be retracted into the rear frame body 101 of the upper frame.

Then, a second locking pin 34 is inserted into each pair of corresponding third positioning pin holes 1121 and fourth positioning pin holes 35, so that the rear support frame 300 remains upright relative to the upper frame rear body 101.

[0040] Through the above operations, the expansion of the hanging basket frame is completed.

[0041] When the stretcher 3 needs to be placed on the upper stretcher platform, the rotating seats 2 of the upper stretcher platform are first rotated inward and positioned in the corresponding stretcher placement area 1, that is, the rotating seats 2 corresponding to the front support rod 21 are rotated inward around the corresponding front support rod 21 on the corresponding first horizontal support plate 41 until the first locking hole faces the second spring ball plunger 42, and the ball head of the second spring ball plunger 42 is inserted into the corresponding first locking hole, so that the rotating seats 2 corresponding to the front support rod 21 are rotated inward into the corresponding stretcher placement area 1 and Position it in a position where it can form an upper stretcher platform together with each rotating seat; at the same time, the rotating seat 2 corresponding to the rear support rod 31 is rotated inwardly around the corresponding rear support rod 31 on the corresponding second horizontal support plate 43 until the second locking hole faces the third spring ball plunger 44. At this time, the ball head of the third spring ball plunger 44 will be inserted into the corresponding second locking hole, thereby rotating the rotating seat 2 inwardly into the corresponding stretcher placement area 1 and positioning it in a position where it can form an upper stretcher platform together with each rotating seat; then place the stretcher 3 on the upper stretcher platform;

[0042] When the rescue aircraft transfers the multi-patient rescue basket containing multiple lying patients to the designated area through the lifting rope, the stretcher is taken out of the basket frame from the upper stretcher platform; when the stretcher placed on the lower stretcher platform needs to be taken out of the basket frame, the rotating seats 2 constituting the upper stretcher platform are first rotated outwards to disengage the locking holes at the bottom of the rotating seats 2 from the ball heads of the corresponding spring ball head plungers, until the rotating seats 2 are rotated out of the corresponding stretcher placement areas, and then the stretcher 3 placed on the lower stretcher platform is lifted up, and the stretcher 3 can be taken out of the basket frame from the lower stretcher platform.

[0043] When the multi-person rescue hanging basket frame is idle, the multi-person rescue hanging basket frame can be folded and stored to reduce storage space. The specific operation process is: first, pull out each first locking pin 24 from the first positioning pin hole 1111 of the corresponding front ear plate 111. At this time, the front support frame 200 can be flipped and folded around the first hinge axis and retracted to the upper frame front frame 100 again, and then the front support frame 200 can be flipped and folded around the first hinge axis and retracted to the upper frame front frame 100 again; then, pull out each second locking pin 34 from the first positioning pin hole 6121 of the corresponding rear ear plate 112. At this time, the rear support frame 300 can be flipped and folded around the second hinge axis and retracted to the upper frame rear frame 101 again, and then the rear support frame 300 can be flipped and folded around the second hinge axis and retracted to the upper frame rear frame 101 again; then, press each first spring ball head column corresponding to each sliding sleeve 18 When the front and rear frames 100 and 101 are folded and retracted, the front and rear frames 100 and 101 are folded and retracted, respectively.

[0044] The advantages of the present invention are: (1) it can carry only four patients lying on stretchers at a time, and the rescue and transportation efficiency is high; (2) the rotating seats constituting the upper stretcher platform can be rotated. When it is necessary to take out the stretcher placed on the lower stretcher platform, the rotating seats constituting the upper stretcher platform can be rotated outward to the corresponding stretcher placement area, so that the stretcher placed on the lower stretcher platform can be moved upward out of the hanging basket frame; (3) the hanging basket frame can be folded and stored when not in use, which reduces the storage space during storage, and is also very convenient when unfolded for use. In addition, through various locking and tightening mechanisms, the stability and safety of the hanging basket frame when unfolded for use are effectively guaranteed.

[0045] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0046] The above description is only a preferred embodiment of the present invention and does not constitute any other form of limitation to the present invention. Any modification or equivalent change made based on the technical essence of the present invention shall still fall within the scope of protection required by the present invention.
