Description

Technical Field

[0001] This utility model relates to the field of rescue stretcher technology, and in particular to a safety protection emergency rescue stretcher. Background Technology

[0002] Rescue stretchers are specialized tools used to transfer the wounded and sick. They can safely transport the injured in scenarios such as disaster sites, medical emergency, battlefield rescue, or mountain search and rescue, and are especially suitable for patients who cannot move on their own or need to maintain a fixed posture.

[0003] In existing technologies, rescue stretchers require rescuers to lower the stretcher height when passing through narrow locations. When passing through narrow locations, rescuers are in a semi-squatting position, which reduces the effectiveness of the rescuers in operating the stretcher and slows down the movement speed of the stretcher in narrow locations. Secondly, since some rescue stretchers need to be used at disaster sites, when patients are lying on the stretcher, debris at the scene is prone to fall and hit the patients, causing secondary injuries. Utility Model Content

[0004] The purpose of this utility model is to provide a safe and protective emergency rescue stretcher to solve the problems mentioned in the background art, such as the rescuer being in a semi-squatting position when passing through narrow places, which reduces the rescuer's ability to operate the stretcher and slows down the stretcher's movement speed in narrow places. Furthermore, when the patient is lying on the stretcher, gravel at the scene is prone to fall and hit the patient, causing secondary injury.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a stretcher mechanism comprising a steel frame, a canvas, handles, a first elastic protective belt, and a second elastic protective belt; a moving mechanism at the bottom of the stretcher mechanism comprising a fixing block, a fixing frame, a storage slot, a toothed plate, an adjusting frame, a moving slot, a moving frame, a spring slot, a connecting spring, a moving plate, a pressing block, a toothed block, and moving wheels; and a protective assembly at the top of the stretcher mechanism comprising a support frame, a Velcro surface, a Velcro hook surface, and a protective cloth.

[0006] In a preferred embodiment, the outer wall of the steel frame is fixedly connected to the inner wall of the canvas, and both ends of the steel frame are fixedly connected to one end of the handle. One side of the canvas is fixedly connected to one side of the first elastic protective belt, and the other side of the canvas is fixedly connected to one side of the second elastic protective belt.

[0007] In a preferred embodiment, the bottom of the steel frame is fixedly connected to the top of the fixing block, and the bottom of the fixing block is fixedly connected to the top of the fixing frame, wherein a storage slot is provided inside the fixing frame.

[0008] In a preferred embodiment, the inner walls of the storage slot are fixedly connected to one side of the toothed plate on both sides, and the inner walls of the storage slot are movably connected to the outer walls of the adjustment frame. The adjustment frame has movable slots on both sides.

[0009] In a preferred embodiment, the bottom of the adjusting frame is fixedly connected to the top of the movable frame, and a spring groove is provided inside the movable frame, with the inner wall of the spring groove fixedly connected to one end of the connecting spring.

[0010] In a preferred embodiment, the other end of the connecting spring is fixedly connected to one side of the movable plate, and the bottom side of the movable plate is fixedly connected to one side of the pressing block, and the top side of the movable plate is fixedly connected to one side of the toothed block.

[0011] In a preferred embodiment, the inner wall of the movable groove is movably connected to the outer wall of the movable plate, and the inner wall of the tooth groove of the toothed plate is movably connected to the outer wall of the toothed block. A movable opening matching the outer wall of the pressing block is provided on one side of the spring groove, and the bottom of the movable frame is fixedly connected to the top of the movable wheel.

[0012] In a preferred embodiment, the top of the steel frame is fixedly connected to the bottom of the support frame, and the top of the support frame is provided with a groove, the inner wall of the groove is fixedly connected to one side of the hook and loop fastener, and the other side of the hook and loop fastener is movably connected to one side of the hook and loop fastener. The top of the hook and loop fastener is fixedly connected to the bottom of the protective cloth.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. This utility model allows for the movement of a pressing block based on the size of the narrow space to be rescued, which in turn moves a moving plate. The moving plate compresses a connecting spring, causing the toothed block to move away from the toothed groove of the toothed plate, thus preventing the moving frame from being locked. Pulling the moving frame then moves the moving wheels, thereby adjusting the height of the moving wheels. When in a narrow space, the rescuer can crouch down, and then the moving wheels will contact the ground, facilitating the use of the stretcher in narrow spaces. By adjusting the height of the moving wheels, the stretcher can be used more conveniently in narrow spaces of different sizes.

[0015] 2. In this invention, when the patient lies on the canvas, the hook side of the Velcro is attached to one side of the loop side, thereby stabilizing the protective cloth above the patient and blocking falling debris. The protective cloth protects the patient and reduces secondary injury from debris. Attached Figure Description

[0026] In one embodiment, the bottom of the steel frame 101 is fixedly connected to the top of the fixing block 201, and the bottom of the fixing block 201 is fixedly connected to the top of the fixing frame 202. The fixing frame 202 has a storage groove 203 inside.

[0027] Specifically: the moving pressing block 211 causes the moving plate 210 to move, and the moving plate 210 compresses the connecting spring 209.

[0028] In one embodiment, the inner walls of the storage groove 203 are fixedly connected to one side of the toothed plate 204 on both sides, and the inner walls of the storage groove 203 are movably connected to the outer walls of the adjustment frame 205. The adjustment frame 205 has movable grooves 206 on both sides.

[0029] Specifically, the storage slot 203 facilitates the movement of the adjustment bracket 205.

[0030] In one embodiment, the bottom of the adjusting frame 205 is fixedly connected to the top of the movable frame 207, and the movable frame 207 has a spring groove 208 inside, with the inner wall of the spring groove 208 fixedly connected to one end of the connecting spring 209.

[0031] Specifically: The height of the moving wheels 213 can be adjusted to make the stretcher more convenient to use in narrow places of different sizes.

[0032] In one embodiment, the other end of the connecting spring 209 is fixedly connected to one side of the movable plate 210, and the bottom side of the movable plate 210 is fixedly connected to one side of the pressing block 211, and the top side of the movable plate 210 is fixedly connected to one side of the toothed block 212.
