In the present embodiment, four hanging basket stretcher lock buckles 4 are provided on both the upper stretcher platform and the lower stretcher platform. Among the four hanging basket stretcher lock buckles 4 on the lower stretcher platform, two hanging basket stretcher lock buckles 4 are respectively installed at the left and right ends of the front beam 72 at the bottom of the front leg frame, and the other two hanging basket stretcher lock buckles 4 are respectively installed at the left and right ends of the rear beam 82 at the bottom of the rear leg frame; the four hanging basket stretcher lock buckles 4 of the upper stretcher platform are respectively correspondingly installed on the four rotating seats 2, that is, each rotating seat 2 is respectively installed with a hanging basket stretcher lock buckle 4; When the stretcher is placed on the stretcher platform, the four hanging basket stretcher lock buckles 4 on the stretcher platform can automatically lock the four support rod ends of the stretcher 3 respectively, so as to automatically lock and fix the stretcher on the corresponding stretcher platform; In this embodiment, if Figure 8 , Fig. 9 , Fig.10 , Fig.11As shown, the structure of the hanging basket stretcher lock 4 includes: a mounting seat 41, a positioning rod 42, a guide member 43, and two locking members 44 arranged on the left and right. The mounting seat 41 is used for fixed installation on the corresponding stretcher platform 5. The positioning rod 42 is vertically fixed to the corresponding stretcher platform 5 and is located directly below the mounting seat 41. A guide hole 431 for inserting the positioning rod is provided at the bottom of the guide member 43. The guide hole 431 of the guide member 43 is aligned with and inserted into the positioning rod 42, so that the guide member 43 is slidably sleeved on the outside of the positioning rod 42. An elastic mechanism is provided between the positioning rod 42 and the guide member 43. The elastic mechanism enables the guide member 43 to always have a tendency to move upward along the positioning rod 42. In this embodiment, the structure of the elastic mechanism includes : A circle of positioning boss 45 is fixed on the outer wall of the guide member 43, and a spring 46 is sleeved on the outside of the positioning rod 42. The upper end of the spring 46 presses upward against the positioning boss 45 of the guide member 43, and the lower end of the spring 46 presses downward against the corresponding stretcher platform 5. Under the elastic force of the spring 46, the guide member 43 always has a tendency to move upward along the positioning rod 42; the lower ends of the two locking members 44 are hinged to the upper end of the guide member 43 through a coaxial hinge shaft 47, and each locking member 44 has a hook-shaped clamping portion 441. The two locking members 44 are arranged relative to each other with a clamping portion arc opening 442 so that the clamping portions 441 of the two locking members 44 together constitute a clamping opening 443, and a waist-shaped long hole is respectively provided on the clamping portions 441 of the two locking members 44 444, two guide pins 48 symmetrically distributed on the left and right sides of the guide member 43 are fixed on the mounting seat 41, each locking member 44 corresponds to the guide pin 48 on the same side, and each guide pin 48 is inserted into the waist-shaped long hole 444 of the corresponding locking member clamping portion 441 on the same side; when no external force is applied downward to the guide member 43, the guide member 43 will move upward relative to the positioning rod 42 under the upward elastic force of the spring 46, and the guide member 43 will synchronously drive the two locking members 44 to move upward when moving upward. In the process of the two locking members moving upward, the clamping portions 441 of the two locking members 44 will automatically open to each other through the respective waist-shaped long holes 444 and the guiding cooperation of the corresponding guide pins 48. At this time, the clamping portions 441 of the two locking members 44 are together The clamping opening 443 can accommodate the support rod of the stretcher 3; when the support rod of the stretcher 3 is placed in the clamping opening, under the gravity of the stretcher 3 and the injured person lying on the stretcher 3, the support rod of the stretcher 3 will press the guide member 43 downward, so that the guide member 43 overcomes the upward elastic force of the spring 46 and moves downward along the positioning rod 42. When the guide member 43 moves downward, it will simultaneously drive the two locking members 44 to move downward. During the downward movement of the two locking members 44, the clamping parts 441 of the two locking members 44 will automatically close to each other through the respective waist-shaped long holes 444 and the corresponding guide pin shafts 48, so that the clamping parts 441 of the two locking members 44 are opposite to each other and clamp the support rod of the stretcher 3, so that the stretcher 3 is automatically locked and fixed on the corresponding stretcher platform;When the stretcher 3 needs to be taken out, it is only necessary to lift the stretcher 3 so that the support rod of the stretcher 3 no longer presses down the guide member 43. At this time, the guide member 43 will automatically move upward relative to the positioning rod 42 under the upward elastic force of the spring 46. When the guide member 43 moves upward, it will synchronously drive the two locking members 44 to move upward again. During the upward movement of the two locking members 44, the clamping portions 441 of the two locking members 44 will automatically open to each other again under the guidance of their respective waist-shaped long holes 444 and the corresponding guide pin shafts 48 to loosen the support rods of the stretcher 3. At this time, the support rods of the stretcher 3 can be lifted upward to separate from the hanging basket stretcher lock 4, thereby lifting the stretcher 3 off the corresponding stretcher platform. When the support rod is inserted downward into the hanging basket stretcher lock buckle 4, the hanging basket stretcher lock buckle 4 will automatically lock the stretcher 3 support rod to lock and fix the stretcher 3 on the corresponding stretcher platform 5. During the entire stretcher placement process, there is no need for any manual operation of the hanging basket stretcher lock buckle, and the entire stretcher placement process saves time and effort, thereby improving the rescue efficiency; and in the process of taking the stretcher out of the corresponding stretcher platform 5, when the stretcher 3 is lifted up, the hanging basket stretcher lock buckle 4 will automatically loosen the stretcher support rod, thereby facilitating the removal of the stretcher 3. During the entire stretcher removal process, there is no need for any manual operation of the hanging basket stretcher lock buckle, and the entire stretcher removal process saves time and effort, thereby improving the rescue efficiency; In addition, since the locking of the stretcher support rod by the hanging basket stretcher lock 4 is due to the fact that the guide member 43 is subjected to the deadweight of the stretcher 3, and the gravity of the stretcher 3 is applied downward to the guide member 43, the guide member will overcome the upward elastic force of the spring 46 and move downward along the positioning rod 42, and then the two locking members 44 will be synchronously driven to move downward, and the clamping parts 441 of the two locking members 44 will automatically close to each other under the guidance of the respective waist-shaped long holes 444 and the corresponding guide pin shafts 48, so that the clamping parts 441 of the two locking members 44 The support rods of the stretcher are clamped in a left-right relative shape, so that the stretcher 3 is automatically locked and fixed on the corresponding stretcher platform 5; in this way, when the stretcher 3 is fixed to the stretcher platform 5 by the hanging basket stretcher lock 4, the injured person is placed on the stretcher 3. Since the gravity of the injured person will also be applied downward to the guide member 43 of the hanging basket stretcher lock 4, the hanging basket stretcher lock 4 will only clamp the stretcher support rods tighter and tighter, thereby further stably fixing the stretcher 3 on the stretcher platform 5 to prevent the stretcher from loosening, and the use stability and safety are high.

[0030] When in use, first unfold the multi-casualty rescue hanging basket to the use state. The specific operation process is as follows: First, unfold the front frame 600, each tube joint 65 and the rear frame 601 of the upper frame into a straight line, and then move each sliding sleeve 68 along the corresponding set of front long rods 62, tube joints 65 and rear long rods 64 until the positioning hole at the front end of the sliding sleeve 68 just corresponds to the mounting hole of the rear section of the front long rod 62, and the positioning hole at the rear end of the sliding sleeve 68 just corresponds to the mounting hole at the front end of the rear long rod 64. At this time, the ball head of the first spring ball head plunger 610 in the mounting hole corresponding to the positioning hole at the front end of the sliding sleeve 68 will be inserted into the positioning hole, and at the same time, the ball head of the first spring ball head plunger 610 in the mounting hole corresponding to the positioning hole at the rear end of the sliding sleeve 68 will be inserted into the positioning hole, thereby positioning and fixing the sliding sleeve 68. At this time, the sliding sleeve 68 just covers the corresponding hinges of the front long rod 62 and the tube joint 65, and the hinges of the rear long rod 64 and the tube joint 65, so that the front frame and the rear frame cannot be turned around the tube joint, so that the upper frame remains flat; Then the front leg frame 700 is rotated around the first hinge axis relative to the upper frame front body 600 to be in an upright position. At this time, the second positioning pin holes 75 of each front leg 71 of the front leg frame just correspond to the first positioning pin holes 6111 of the corresponding front ear plates 611 in the upper frame front body 600. Then, a first locking pin 74 is inserted into each pair of corresponding first positioning pin holes 6111 and second positioning pin holes 75, so that the front leg frame 700 remains in an upright position relative to the upper frame front body 600. Then, the rear leg frame 800 is rotated around the second hinge axis relative to the upper frame rear body 601 to be in an upright position. At this time, the fourth positioning pin holes 85 of each rear leg 81 of the rear leg frame just correspond to the third positioning pin holes 6121 of each corresponding rear ear plate 612 in the upper frame rear body 601. Then, a second locking pin 84 is inserted into each pair of corresponding third positioning pin holes 6121 and fourth positioning pin holes 85, so that the rear leg frame 800 remains in an upright position relative to the upper frame rear body 601. Through the above operations, the expansion of the hanging basket frame is completed; Then, the safety fence 10 is wrapped around the four sides and the bottom of the hanging basket frame, and each anti-collision pad 11 is detachably bound to the hanging basket frame 100 through a net rope with Velcro; at this time, the multi-injured rescue hanging basket is in an unfolded use state.

[0031] When in use, when the stretcher 3 needs to be placed on the lower stretcher platform, the rotating seats 2 of the upper stretcher platform are first rotated outward to the corresponding stretcher placement area, and then the ends of the four support rods of the stretcher 3 are aligned and placed in the clamping openings 443 of the four hanging basket stretcher buckles 4 of the lower stretcher platform. After the ends of the support rods of the stretcher 3 are clamped into the hanging basket stretcher buckles 4, under the action of the gravity of the stretcher 3 and the injured person lying on the stretcher 3, the support rods of the stretcher 3 will press down the guide pieces 43 of the hanging basket stretcher buckles 4, so that the guide pieces 43 of the hanging basket stretcher buckles 4 can be moved downward. The guide member 43 overcomes the upward elastic force of the spring 46 and moves downward along the positioning rod 42. When the guide member 43 moves downward, it will simultaneously drive the two locking members 44 to move downward. During the downward movement of the two locking members 44, the clamping parts 441 of the two locking members 44 will automatically close to each other through the cooperation of their respective waist-shaped long holes 444 and the corresponding guide pin shafts 48, so that the clamping parts 441 of the two locking members 44 are opposite to each other and clamp the support rod of the stretcher 3, so that the stretcher 3 is automatically locked and fixed on the corresponding stretcher platform; When the stretcher 3 is to be placed on the upper stretcher platform during use, each rotating seat 2 of the upper stretcher platform is first rotated inwards and positioned in the corresponding stretcher placement area 1, that is, the rotating seat 2 corresponding to the front leg 71 is rotated inwards around the corresponding front leg 71 on the corresponding first horizontal support plate 91 until the first locking hole faces the second spring ball plunger 92, and the ball head of the second spring ball plunger 92 is inserted into the corresponding first locking hole, so that the rotating seat 2 corresponding to the front leg 71 is rotated inwards into the corresponding stretcher placement area 1 and positioned at a position that can form the upper stretcher platform together with each rotating seat; at the same time, the rotating seat 2 corresponding to the rear leg 81 is rotated inwards around the corresponding rear leg 81 on the corresponding second horizontal support plate 93 until the second locking hole faces the third Spring ball head plunger 94, at this time, the ball head of the third spring ball head plunger 94 will be inserted into the corresponding second locking hole, so that the rotating seat 2 is rotated inwardly into the corresponding stretcher placement area 1 and positioned at a position that can form an upper stretcher platform together with each rotating seat; by positioning each rotating seat 2, the hanging basket stretcher lock buckle 4 of each rotating seat 2 can be positioned at the same time, so that the four hanging basket stretcher lock buckles 4 that constitute the upper stretcher platform just correspond to the four support rod ends of the stretcher 3; then the four support rod ends of the stretcher 3 are aligned and placed in the clamping openings 443 of the four hanging basket stretcher lock buckles 4 of the upper stretcher platform, so that the four hanging basket stretcher lock buckles 4 automatically clamp the four support rod ends of the stretcher 3, thereby automatically locking and fixing the stretcher 3 on the upper stretcher platform.

[0032] After the rescue aircraft transfers the multi-injured rescue basket containing multiple lying injured persons to the designated area through the lifting rope, it is only necessary to lift the stretcher placed on the upper stretcher platform, so that the stretcher can be removed from the upper stretcher platform and the basket can be taken out; when it is necessary to take out the stretcher placed on the lower stretcher platform, 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, so that the stretcher 3 can be removed from the lower stretcher platform and the basket can be taken out.

[0033] When the multi-injured rescue hanging basket is idle, it can be folded and stored to reduce the storage space. The specific operation process is: first remove the anti-collision pad 11 and the safety fence 10, and then pull out each first locking pin 74 out of the first locating pin hole 6111 of the corresponding front ear plate 611. At this time, the front leg frame 700 can be flipped and folded around the first hinge axis and gathered in the upper frame front frame 600 again, and then the front leg frame 700 can be flipped and folded around the first hinge axis and gathered in the upper frame front frame 600 again; then pull out each second locking pin 84 out of the first locating pin hole 6121 of the corresponding rear ear plate 612. At this time, the rear leg frame 800 can be flipped and folded around the second hinge axis and gathered in the upper frame rear frame 601 again, and then the rear leg frame 800 can be flipped and folded around the second hinge axis and gathered in the upper frame rear frame 601 again; then press each sliding sleeve 68 corresponding The ball heads of the first spring ball head plungers 610 are disengaged from the corresponding sliding sleeve positioning holes 69, and the sliding sleeve 68 can move along the front long rod and the rear long rod. Then, the sliding sleeve 68 is moved along the corresponding front long rod 62 and the rear long rod 64 until it does not cover the hinged joints between the front long rod 62 and the pipe joint 65, and the hinged joints between the rear long rod 64 and the pipe joint 65. At this time, the front frame 600 and the rear frame 601 are It can be flipped around the tube joint 65 again, and then the front frame 600 and the rear frame 601 are flipped around the tube joint 65, so that the front frame 600 and the rear frame 601 are folded and gathered to complete the folding and gathering of the upper frame; and at this time, the front leg frame 700 and the rear leg frame 800 are also just located in the leg frame storage space formed after the upper frame is folded and gathered, thereby completing the folding and storage of the multi-injured rescue hanging basket, and the storage space of the multi-injured rescue hanging basket after folding and storage is small.
