When rotating, the four center drive gears 214 rotate outward synchronously, and when the center drive gear 214 in the upper right corner rotates inward, the four center drive gears 214 rotate inward synchronously, and the distal arm body of the second auxiliary arm 218 on the center drive gear 214 is hinged with the distal arm body of the first auxiliary arm 216 on the displacement plate gear 213, and the center drive shaft 215 is rotatably set on the seat shell 201, and the toggle handle 222 is set on the outside of the seat shell 201. The reset gear 219, the center drive gear 214 and the ratchet 223 are set inside the seat shell 201, and the reset tooth arm 220 is set below the reset gear 219 and meshes with the reset gear 219. The reset spring 221 pushes the reset tooth arm 220. In the initial state,The central driving gear 214 on the central driving shaft 215 is in the inner extension rotation structure. At this time, the four central driving gears 214 inside the seat shell 201 are synchronously in the inner extension rotation structure. The toggle support rod 226 slides in the arc-shaped slide groove 209. The pawl 224 is rotatably arranged on the inner wall of the seat shell 201. The toggle block 227 is arranged on the outer side of the seat shell 201. Through the resistance of the resistance spring 225 to the bottom of the pawl 224, the top of the pawl 224 and the ratchet 223 form a one-way limited rotation structure of the ratchet pawl.

[0031] The working principle of the present invention is as follows: when treating and transferring a patient with limb trauma in the wild, the patient is allowed to lie flat on the transport sheet 109, and then the two transport single arms 101 are lifted. During the lifting process, the patient's own weight exerts a vertical downward pulling force on the central ball head 104 through the transport sheet 109 and the suspension arm 106. Since the central ball head 104 rotates in the inner ball groove table 103, the inner ball groove table 103 rotates in the outer ball groove table 102, and the first shaft rod 110 and the second shaft rod 111 are in a vertical distribution structure on the same horizontal plane, that is, the central ball head 104 and the inner ball groove table 103 are in a vertical distribution structure. 03 A vertical rotating structure is formed in the outer ball groove table 102, and the patient's own weight exerts a downward pulling force on the central ball head 104. When the patient is transferred and transported by the transport arm 101, when the transport arm 101 shakes or tilts, through the cooperation of the above structure, the transport sheet 109 under the suspension arm 106 is always in a vertical downward arrangement structure. In this way, an anti-shaking patient lying flat transfer and transportation structure is formed on the transfer and transportation frame assembly 100, that is, the anti-shaking transfer and transportation of the patient's body can be achieved through the patient's own weight and the above vertical rotating structure.

[0032] On the basis of the above, the limb rescue guard plate assembly 200 of the present invention is arranged on the top of the center ball head 104. When the anti-sway transfer and transportation structure is formed at the bottom of the center ball head 104, the limb rescue guard plate assembly 200 on the top of the center ball head 104 also forms an anti-sway structure. Since the limb rescue guard plate assembly 200 is used to tow and prevent the patient's limbs, the patient's injured limb forms an anti-sway towing and placement structure on the top of the center ball head 104. Through the cooperation of the above structures, that is, through the patient's own weight and the above-mentioned vertical rotation structure, the anti-sway transfer and transportation of the patient's body is formed below the center ball head 104, and the anti-sway towing structure of the patient's limbs is formed above the center ball head 104. In this way, the safety of the patient's transfer and transportation is guaranteed to the greatest extent, and secondary injuries are avoided.

[0033] On the basis of the above, the patient's limb of the present invention is placed on the limb rescue guard assembly 200. When the patient's limb is dragged and fixed by the limb rescue guard assembly 200, the center drive shaft 215 is driven to rotate clockwise by the toggle handle 222. At this time, the reset gear 219, the center drive gear 214 and the ratchet 223 on the center drive shaft 215 rotate clockwise synchronously. During the clockwise rotation, the four adjacent meshing center drive gears 214 are synchronously extended. At this time, the second auxiliary arm 218 on the center drive gear 214 drives the first auxiliary arm 216 on the displacement plate gear 213 to extend. The two adjacent displacement plate gears 213 are meshed. At this time, when the second auxiliary arm 218 and the first auxiliary arm 216 are synchronously abducted, the distance between the first guard plate 206 and the second guard plate 205 is reduced, that is, a clamping splint structure is formed. In this way, the clamping splint fixation of the limb is achieved. Through the splint fixation, the limb fracture can be limited to avoid subsequent secondary injuries. At the same time, the inner sides of the first guard plate 206 and the second guard plate 205 are provided with trauma treatment cotton 207 with medicine solution or powder. When the limb is clamped and fixed with a splint, the medicine solution or powder on the trauma treatment cotton 207 is used to treat and relieve the limb injury.

[0034] On the basis of the above, when the center drive shaft 215 rotates clockwise to achieve the contact and closeness between the first guard plate 206 and the second guard plate 205, a ratchet 223 is arranged on the center drive shaft 215 of the present invention, and at the same time, the pawl 224 of the present invention is rotatably arranged on the inner wall of the seat shell 201, and the contact spring 225 contacts the bottom of the pawl 224, and the top of the pawl 224 and the ratchet 223 form a one-way limiting rotation structure of the ratchet pawl, that is, when adjusting the clamping distance between the first guard plate 206 and the second guard plate 205 for the limb, it is only necessary to rotate the toggle handle 222 clockwise. Through the above-mentioned one-way limiting rotation structure, in combination with the reset meshing force of the reset spring 221 on the reset gear 219 through the reset tooth arm 220, the real-time fixation of the limb clamping distance can be achieved.

[0035] On the basis of the above, the first guard plate 206 and the second guard plate 205 of the present invention are respectively rotatably arranged on the second displacement plate 212 and the first displacement plate 217 through the guard plate shaft 210, and cooperate with the tension on both sides of the tension spring 211. Through this rotation structure, the first guard plate 206 and the second guard plate 205 can clamp and fit themselves according to the characteristics of one end of the limb being thick and the other end when splinting the limb, thereby effectively ensuring that the first guard plate 206 and the second guard plate 205 effectively fit and splint the limb. At the same time, the T-shaped slider 203 at the bottom of the limb rescue guard plate assembly 200 of the present invention slides in the slide arm 105 at the top of the center ball head 104. By tightening the tightening screw 204, the limb rescue guard plate assembly 200 is fixed on the arm body of the slide arm 105. In this way, the lateral position of the limb rescue guard plate assembly 200 on the transfer and transport frame assembly 100 can be conveniently adjusted to facilitate the use of patients.

[0036] In another embodiment of the present invention, the position of the outer ball groove table 102 of the present invention can be arranged on the outside of the transport arm 101 in a height-adjustable manner. In this way, the relative height adjustment of the limb rescue guard plate assembly 200 during actual use can be achieved.

[0037] In another embodiment of the present invention, the connection method of the auxiliary elastic belt 108 of the present invention between the transport single arm 101 and the cross arm 107 is conventional technology and can be fixed by hook type, so it is not repeated. The connection method of the transport sheet 109 of the present invention between the two cross arms 107 is conventional technology and can be fixed by hook type, so it is not repeated.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
