[0038] When retracting or releasing, the second hollow column 8 can limit the position of the movable plate 4 inside the first movable groove. At the same time, the coordinated arrangement of the plurality of first springs 6 and the plug column 7 can further limit the position of the movable plate 4 inside the first movable groove, thereby fixing the movable plate 4 at the top inside the first movable groove.

[0039] When the second hollow column 8 is inserted into the inner side of the movable plate 4, the second spring 11 inside the second hollow column 8 can push the sliding rod 10 to move away from the end of the first fixed rod 9, so that the sliding rod 10 can drive the driving plate 12 to move synchronously. The clearance cooperation setting of the card block fixedly connected with the driving plate 12 and the rotating limit plate 14 can drive the card block to move synchronously while the driving plate 12 moves away from the first fixed rod 9, and make the rotating limit plate 14 rotate with the second fixed rod 13 as the center of the circle, so that the two rotating limit plates 14 on both sides of the second hollow column 8 can respectively rotate out of the inner side of the third movable groove, and cooperate with the inner side wall of the movable plate 4 for extrusion and limit, so as to limit the position of the second hollow column 8, so as to avoid the second hollow column 8 from being separated from the inner side of the movable plate 4 when placed or moved, and affecting the normal use of the transfer platform;

[0040] Through the connection setting of the third hollow column 16, while the second hollow column 8 fixes the movable disk 4 to the top of the first movable groove, the rotating disk 17 can also drive the unfolding rod 22 vertically stored with the rotating disk 17 to be inserted into the inner side of the second movable groove. At this time, the end of the unfolding rod 22 away from the rotating disk 17 will have the effect of plugging and limiting with the insertion rod 3 on the inner side of the second movable groove, thereby preventing the unfolding rod 22 from being separated from the limit of the insertion rod 3 and automatically unfolding when placed or moved.

[0041] When in use, by driving the sliding rod 10 toward one end of the first fixed rod 9, the driving plate 12 outside the sliding rod 10 can drive the block of the rotating limit plate 14 to move synchronously, and drive the rotating limit plate 14 to move to the inside of the third movable groove. At this time, by driving the second hollow column 8 to be pulled out of the inside of the movable plate 4, the limiting effect on the movable plate 4 can be cancelled;

[0042] By setting the fixing buckle 2, the device can be hung as a whole on the bottom of the helicopter, so as to facilitate the deployment of the transfer platform;

[0043] When the fixing buckle 2 is suspended, the movable plate 4 will move downward by the gravity of the device fixedly connected to the bottom of the movable plate 4, and at this time, the top of the deployment rod 22 will also break away from the insertion limit effect of the insertion rod 3;

[0044] At the same time, through the arrangement of multiple counterweights 23, multiple deployment rods 22 can be driven to flip inside the rotating groove of the rotating disk 17 by their own gravity, so that the support net 37 is driven to be opened by multiple deployment rods 22. At the same time, through the arrangement of the first pull wire 27, the deployment rods 22 can be supported and pulled, so that it is convenient to carry people and rescue materials on the top of the support net 37.

[0045] When the deployment rod 22 is opened, the second rotating seat 24 close to one end of the rotating disk 17 can drive the second pull wire 28 to move toward the end away from the rotating disk 17. At this time, the other end of the second pull wire 28 will drive the sliding disk 19 to move downward outside the third hollow column 16. At this time, the sliding disk 19 can drive the lock buckle 20 to move downward synchronously. Through the setting of the lock buckle 20, the safety belts of the passengers and the rescue materials can be connected, so as to further connect the passengers and the rescue materials placed on the top of the supporting net 37, so as to prevent the passengers and the rescue materials from falling off the top of the supporting net 37 during the transportation process, thereby improving the safety of the transportation device.

[0046] When it is necessary to store the unfolding rod 22 and the supporting net 37, the motor 34 can be turned on, and the output end of the motor 34 can drive the storing rod 35 to rotate. At this time, the storing rod 35 can wind and store the fourth pull wire 36, and the top of the fourth pull wire 36 drives the movable disk 30 to move downward on the inner side of the third hollow column 16. At this time, through the setting of the fourth rotating seat 31, the end of the fifth rotating seat 32 located on the inner side of the third hollow column 16 can be driven to move downward, so that the end of the fifth rotating seat 32 located on the outer side of the third hollow column 16 can drive the fifth rotating seat 32 to move upward, so that the sliding plate 19 fixedly connected to the fifth rotating seat 32 can be driven to move synchronously upward on the outer side of the third hollow column 16;

[0047] When the sliding disk 19 moves upward, it can drive the first rotating seat 21 at the bottom of the sliding disk 19 to move synchronously. At the same time, through the setting of the second pull wire 28, the second rotating seat 24 close to one end of the rotating disk 17 can be pulled, and the second rotating seat 24 can drive the unfolding rod 22 to flip inside the rotating groove. By synchronously storing the five unfolding rods 22, the supporting net 37 fixedly connected between the multiple unfolding rods 22 can be synchronously stored, so that the supporting net 37 and the unfolding rod 22 can be automatically closed, thereby improving the efficiency of the second rescue by using less time for closing the platform.
