[0015] 1. The utility model provides a foldable first aid stretcher for emergency department rescue. By pulling the pull rod, the pull rod drives the ratchet teeth to move synchronously, the ratchet teeth drive the first spring to contract, and at the same time, the ratchet teeth drive the guide rod to slide on the inner wall of the fixed plate. The guide rod guides the ratchet teeth so that the ratchet teeth will not shift when moving. Thus, the outer wall of the ratchet teeth is no longer engaged with the outer wall of the gear. Subsequently, the support frame can be rotated downward, and the inner wall of the support frame squeezes the outer wall of the limit rod, causing the limit rod to slide and driving the pull plate to move synchronously. The pull plate drives the second spring to stretch. Thus, the outer wall of the limit rod is no longer inserted into the inner wall of the support frame. When the support frame rotates by a certain degree, the rotation can be stopped. At this time, the pull rod is released, and under the action of the elastic force of the first spring, the ratchet teeth are engaged with the outer wall of the gear again, thereby limiting the gear and making the gear and the rotating shaft unable to rotate. Thus, the support frame cannot rotate, increasing the stability of the device and achieving the effect of increasing stability.

[0016] 2. The utility model provides a foldable first aid stretcher for emergency department rescue. By pulling the clamping plate, the clamping plate no longer blocks the guardrail. Subsequently, the guardrail is rotated. When the guardrail rotates half a circle, the clamping plate is released at this time. Under the action of the elastic force of the third spring, the outer wall of the clamping plate is inserted into the inner wall of the guardrail. Thus, the guardrail is limited to prevent the guardrail from rotating. Thus, the guardrail protects the patient and prevents the patient from slipping off the stretcher body, achieving the effect of protection. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] As Figures 1 - 5 shown, a folding first aid stretcher for emergency department rescue includes a stretcher body 1. A support plate 11 is fixedly connected to the right part of the bottom end of the stretcher body 1. A support wheel 12 is fixedly connected to the left part of the bottom end of the stretcher body 1. Folding mechanisms 2 are rotatably connected to both the left and right parts of the stretcher body 1. Limiting mechanisms 3 are fixedly connected to both the front and rear ends of the stretcher body 1. A protective mechanism 4 is rotatably connected to the top of the stretcher body 1. The folding mechanism 2 includes two rotating shafts 21. The outer wall of the rotating shaft 21 is rotatably connected to the inner wall of the stretcher body 1. The limiting mechanism 3 includes a second spring 33. One end of the second spring 33 is fixedly connected to the outer wall of the stretcher body 1. The protective mechanism 4 includes a guardrail 41. The bottom of the guardrail 41 is rotatably connected to the top of the stretcher body 1.

[0025] The device can be folded up or unfolded through the folding mechanism 2, which increases the practicability of the device. During use, the patient can be protected by the protective mechanism 4 to prevent the patient from falling off the stretcher body. During folding, the support frame 22 in the folding mechanism 2 can be limited and supported by the limiting mechanism 3 to make the folding more stable.

[0026] As Figure 2 、 Figure 3 shown, a support frame 22 is fixedly connected to the outer wall of the rotating shaft 21. A wheel 23 is rotatably connected to the bottom of the support frame 22. A gear 24 is fixedly connected to the front part of the rotating shaft 21. A toothed block 25 is clamped on the outer wall of the gear 24. A pull rod 26 is fixedly connected to one end of the toothed block 25. A fixing plate 28 is slidably connected to the outer wall of the pull rod 26. The outer wall of the fixing plate 28 is fixedly connected to the outer wall of the stretcher body 1. A first spring 27 is movably sleeved on the outer wall of the pull rod 26. One end of the first spring 27 is fixedly connected to one end of the toothed block 25. One end of the first spring 27 is fixedly connected to one end of the fixing plate 28. A guide rod 29 is slidably connected to the inner wall of the fixing plate 28. One end of the guide rod 29 is fixedly connected to one end of the toothed block 25.

[0027] By pulling the pull rod 26, the pull rod 26 drives the tooth 25 to move synchronously. The tooth 25 drives the first spring 27 to contract. At the same time, the tooth 25 drives the guide rod 29 to slide on the inner wall of the fixed plate 28. The guide rod 29 guides the tooth 25 so that the tooth 25 will not shift during movement. Thus, the outer wall of the tooth 25 is no longer engaged with the outer wall of the gear 24. Subsequently, the support frame 22 can be rotated downward, so that the inner wall of the support frame 22 squeezes the outer wall of the limit rod 32, causing the limit rod 32 to slide and driving the pull plate 31 to move synchronously. The pull plate 31 drives the second spring 33 to stretch. Thus, the outer wall of the limit rod 32 is no longer inserted into the inner wall of the support frame 22. When the support frame 22 rotates 90 degrees, the rotation can be stopped. At this time, the pull rod 26 is released. Under the action of the elastic force of the first spring 27, the tooth 25 is engaged with the outer wall of the gear 24 again, thereby limiting the gear 24 and making the gear 24 and the rotating shaft 21 unable to rotate. Thus, the support frame 22 cannot rotate, increasing the stability of the device and achieving the effect of increasing stability.

[0028] As Figure 2 , Figure 4 shown, one end of the second spring 33 is fixedly connected to a pull plate 31. One end of the pull plate 31 is fixedly connected to a limit rod 32. The outer wall of the limit rod 32 is movably sleeved with the inner wall of the second spring 33. The outer wall of the limit rod 32 is slidably connected to the inner wall of the stretcher body 1. The outer wall of the limit rod 32 is inserted into the inner wall of the support frame 22.

[0029] When folding, the outer wall of the support frame 22 is inserted into the inner wall of the stretcher body 1. During the insertion process, the outer wall of the support frame 22 contacts the outer wall of the limit rod 32. Due to the special shape of the limit rod 32, when the outer wall of the support frame 22 contacts the outer wall of the limit rod 32, the limit rod 32 drives the pull plate 31 to move synchronously, stretching the second spring 33. When the outer wall of the support frame 22 is completely inserted into the inner wall of the stretcher body 1, at this time, under the action of the elastic force of the second spring 33, the outer wall of the limit rod 32 is inserted into the inner wall of the support frame 22, thereby limiting and supporting the support frame 22 and making its folding more stable.

[0030] As Figure 2 , Figure 5 shown, a rubber block 42 is fixedly connected to the outer wall of the guardrail 41. The shape of the rubber block 42 is hemispherical. A clamping plate 43 is inserted at the bottom of the guardrail 41. A guide block 44 is fixedly connected to the bottom end of the clamping plate 43. The outer wall of the guide block 44 is slidably connected to the inner wall of the stretcher body 1. A third spring 45 is fixedly connected to the top of the clamping plate 43. One end of the third spring 45 is fixedly connected to a connecting plate 46. The bottom end of the connecting plate 46 is fixedly connected to the top end of the stretcher body 1. The bottom of the connecting plate 46 is slidably connected to the outer wall of the clamping plate 43.

[0031] By pulling the clamping plate 43, the third spring 45 is driven to stretch. At the same time, the clamping plate 43 drives the guiding block 44 to slide on the inner wall of the stretcher body 1. The guiding block 44 limits and guides the clamping plate 43, making the movement of the clamping plate 43 smoother. Thus, the clamping plate 43 no longer blocks the guardrail 41. Subsequently, the guardrail 41 is rotated, causing the guardrail 41 to drive the rubber block 42 to move synchronously, so that the outer wall of the rubber block 42 is no longer clamped with the inner wall of the stretcher body 1. After the guardrail 41 rotates half a circle, the clamping plate 43 is released at this time. Under the action of the elastic force of the third spring 45, the outer wall of the clamping plate 43 is inserted into the inner wall of the guardrail 41, thereby limiting the guardrail 41 to prevent it from rotating. Thus, the guardrail 41 protects the patient and prevents the patient from slipping off the stretcher body 1, achieving a protective effect.

[0032] Working principle of the utility model: When in use, place the stretcher body 1 on the ground so that the bottom ends of the support plate 11 and the support wheels 12 are in contact with the ground. Then place the patient on the stretcher body 1. After that, pull the clamping plate 43 to drive the third spring 45 to stretch. At the same time, the clamping plate 43 drives the guide block 44 to slide on the inner wall of the stretcher body 1. The guide block 44 limits and guides the clamping plate 43, making the movement of the clamping plate 43 more stable. Thus, the clamping plate 43 no longer blocks the guardrail 41. Then rotate the guardrail 41, so that the guardrail 41 drives the rubber block 42 to move synchronously, and the outer wall of the rubber block 42 is no longer clamped with the inner wall of the stretcher body 1. When the guardrail 41 rotates half a circle, at this time release the clamping plate 43. Under the action of the elastic force of the third spring 45, the outer wall of the clamping plate 43 is inserted into the inner wall of the guardrail 41. Thus, the guardrail 41 is limited to prevent the guardrail 41 from rotating. Thus, the guardrail 41 protects the patient and prevents the patient from slipping off the stretcher body 1, achieving a protective effect. After that, lift the stretcher body 1. According to the need, choose whether to extend the support frame 22 and the wheels 23. When extension is needed, pull the pull rod 26, so that the pull rod 26 drives the gear teeth 25 to move synchronously. The gear teeth 25 drive the first spring 27 to contract. At the same time, the gear teeth 25 drive the guide rod 29 to slide on the inner wall of the fixed plate 28. The guide rod 29 guides the gear teeth 25, so that the gear teeth 25 will not deviate when moving. Thus, the outer wall of the gear teeth 25 is no longer clamped with the outer wall of the gear 24. Then the support frame 22 can be rotated downward, so that the inner wall of the support frame 22 squeezes the outer wall of the limit rod 32, making the limit rod 32 slide and driving the pull plate 31 to move synchronously. The pull plate 31 drives the second spring 33 to stretch. Thus, the outer wall of the limit rod 32 is no longer inserted into the inner wall of the support frame 22. When the support frame 22 rotates 90 degrees, the rotation can be stopped. At this time, release the pull rod 26. Under the action of the elastic force of the first spring 27, the gear teeth 25 are clamped with the outer wall of the gear 24 again. Thus, the gear 24 is limited, and the gear 24 and the rotating shaft 21 cannot rotate. Thus, the support frame 22 cannot rotate, increasing the stability of the device and achieving the effect of increasing stability. When the use is over, the support frame 22, the wheels 23 and the guardrail 41 of the device can all be folded to reduce the space occupied by the device. Thus, the use experience is greatly improved.
