Embodiment

[0022] Please refer to Figure 1 - Figure 3 , an emergency stretcher trolley, including a stretcher board 1 and connecting blocks 2 fixedly installed at the four corners of the lower end of the stretcher board 1. Support legs 3 are rotatably installed in the connecting blocks 2. Universal wheels 31 are fixedly installed at the lower ends of the support legs 3. Limit components 21 are installed on both sides of the connecting blocks 2. The limit component 21 includes a housing 211 fixedly installed on the side wall of the connecting block 2. Slide grooves 212 are respectively opened inside the housing 211. Slide blocks 213 are slidably connected in the slide grooves 212. A spring 214 is fixedly installed between the inner wall of the slide block 213 and the inner wall of the slide groove 212.

[0023] When using this stretcher trolley, first turn the four support legs 3 at the lower end from the inner side of the stretcher board 1 to a direction perpendicular to the stretcher board 1. When the support legs 3 rotate, they will contact the limit component 21 on the side of the connecting block 2. At this time, the side wall of the support leg 3 contacts the slide block 213. When the support leg 3 continues to rotate, the two slide blocks 213 on both sides are squeezed by the side wall of the support leg 3 and slide into the inside of the slide groove 212. At this time, the support leg 3 can be freely rotated. When the support leg 3 is rotated to be perpendicular to the upper stretcher board 1, at this time, under the action of the spring 214, the slide block 213 can be automatically pushed outwards. At this time, the two slide blocks 213 are located on the side of the support leg 3. Without the action of a large external force, the movement of the support leg 3 can be restricted to make it at an angle perpendicular to the stretcher board 1. When storage is required, rotate the support leg 3 to an angle parallel to the stretcher board 1. When this emergency stretcher trolley needs to be used, the stretcher can be unfolded by rotating the support legs 3 and put into use. When it is not needed, each support leg 3 can be folded to facilitate the storage of this device and save space. Embodiment

[0024] Please refer toFigure 2 - Figure 5 For both of the four adjacent sides of the two sliders 213 that are close to each other, they are arc-shaped surfaces. Grooves 201 are formed on the side surfaces of the connecting block 2. The support legs 3 are rotatably connected in the grooves 201. With the cooperation among the slider 213, the connecting block 2, the groove 201 and the support legs 3, when the support legs 3 come into contact with the slider 213, a relatively large external force can be used to push the slider 213 to slide.

[0025] Grooves 11 are formed on both sides of the stretcher board 1. An activity baffle component 4 is jointly installed between the two side walls of the groove 11. The activity baffle component 4 includes a fixing rod 41 fixedly installed between the two side walls of the groove 11. With the cooperation among the stretcher board 1, the groove 11 and the fixing rod 41, fixing rods 41 are installed on both sides of the stretcher board 1.

[0026] A connecting rod 42 is rotatably installed on the fixing rod 41. A connecting plate 43 is fixedly installed on the side wall of the connecting rod 42. With the cooperation among the fixing rod 41, the connecting rod 42 and the connecting plate 43, the connecting plate 43 can rotate on the fixing rod 41.

[0027] One end of the connecting plate 43 is slidably connected with a baffle 44. Slots 12 are formed on both sides of the groove 11. The baffle 44 can be slidably connected in the slots 12. With the cooperation among the connecting plate 43, the baffle 44, the groove 11 and the slots 12, the baffle 44 can be fixed through the slots 12.

[0028] Receiving grooves 13 are formed on both sides of the lower end of the stretcher board 1. The baffle 44 can be rotatably connected in the receiving grooves 13. With the cooperation among the stretcher board 1, the receiving grooves 13 and the baffle 44, the baffle 44 can be folded and received through the receiving grooves 13.

[0029] When using this device, first rotate the four support legs 3 on the side so that they are all at an angle perpendicular to the stretcher board 1. At this time, the activity baffle component 4 received in the receiving grooves 13 at the lower end is in a movable state. Rotate the baffle 44 outward along the groove 11 to an angle perpendicular to the stretcher board 1. When the baffle 44 moves, it drives the connecting plate 43 and the connecting rod 42 to rotate along the fixing rod 42. When the baffle 44 is rotated to be opposite to the slot 12 at the upper end of the stretcher board 1, the baffle 44 can be pushed into the slot 12. At this time, the baffle 44 slides downward along the connecting rod 43 and slides into the slot 12. Just slide both side baffles 44 into the slots 12. At this time, under the action of the slots 12, the baffle 44 is in a non-movable state. Then the patient can be placed inside the stretcher board 1 between the baffles 44. After the support legs 3 are unfolded, this device can rotate and unfold the activity baffle component 4 and fix both side baffles 44 on both sides of the stretcher board 1, which can prevent the wounded from sliding and causing secondary injuries from slipping off the side during the transportation of the wounded.
