[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 This utility model provides a technical solution: a stretcher cart that is easy to transfer, including a mobile frame 1, a support frame 2 and two sets of railings 3. The support frame 2 is fixedly installed on the top of the mobile frame 1, and the two sets of railings 3 are symmetrically arranged on the top of the support frame 2. The mobile frame 1 serves as the basic support structure and is equipped with casters for easy movement. The support frame 2 is fixedly connected to the top of the mobile frame 1 by bolts to form a stable support platform. The two sets of railings 3 are symmetrically installed on both sides of the support frame 2 to form a safety protection structure.

[0025] Two sets of fixed seats 4 are fixedly installed at the bottom of the support frame 2. Each set of fixed seats 4 has an adjustment component 5 inside. The adjustment component 5 can be used to lower and store the fence 3, which facilitates the transfer of patients. The fixed seats 4 are equipped with an adjustment mechanism, which can realize the lifting and lowering function of the fence 3, thus solving the problem of obstacles in the transfer of patients by traditional stretcher carts.

[0026] The adjustment assembly 5 includes a first threaded rod 51, a movable plate 52, a handwheel 53, and a first through hole 54. The first threaded rod 51 is rotatably installed inside the fixed base 4, and the bottom end of the first threaded rod 51 passes through the fixed base 4 and is fixedly connected to the top of the handwheel 53. The movable plate 52 is threaded to the outside of the first threaded rod 51. By rotating the handwheel 53, the first threaded rod 51 can be rotated, thereby raising and lowering the movable plate 52. The top of the fixed base 4 has multiple sets of first through holes 54 for the sliding of the fence 3.

[0027] The manual adjustment function of the fence 3 height is realized by setting the first threaded rod 51, the movable plate 52, the handwheel 53 and the first through hole 54, which solves the technical problem that the traditional fixed fence 3 cannot be adjusted. The first threaded rod 51 is installed inside the fixed seat 4 through the bearing to ensure smooth rotation. Its bottom end extends out of the fixed seat 4 and is rigidly connected to the handwheel 53 to form a manual operation interface, which makes it convenient for the staff to adjust the fence 3 by raising and lowering. The movable plate 52 cooperates with the first threaded rod 51 through the thread to convert the rotational motion into linear motion. The multiple sets of first through holes 54 opened on the top of the fixed seat 4 provide a precise sliding track for the fence 3 to ensure the stability of the raising and lowering process.

[0028] In a further preferred embodiment, the adjustment component 5 also includes a slider 55 and a groove 56; sliders 55 are fixedly installed on both sides of the movable plate 52, and grooves 56 are installed on both sides inside the fixed base 4. The sliders 55 slide in the grooves 56 to limit the axial movement of the movable plate 52. The sliders 55 and the grooves 56 are set to achieve precise guidance of the movement of the movable plate 52, solve the problem of shaking and offset that may occur during the adjustment process, and ensure the stability and safety of the raising and lowering of the fence 3.

[0029] The support frame 2 has multiple sets of second through holes 6 at its bottom. The fence 3 is slidably installed in the second through holes 6. Through the cooperation between the second through holes 6 at the bottom of the support frame 2 and the fence 3, the fence 3 can slide smoothly, which solves the problem of frictional resistance during the movement of the fence 3 and ensures that the operation is easy and effortless.

[0030] Preferably, the top of the support frame 2 is provided with two sets of grooves 7 for receiving the lowered fence 3. The grooves 7 are designed to completely receive the fence 3. After receiving the fence 3, the top surface of the fence 3 is flush with the plane of the support frame 2, forming a continuous support surface without protrusions. This solves the problem of obstruction caused by the traditional fence 3 when transferring patients, allowing medical staff to move the patient to the bed or operating table more smoothly without having to lift the patient. This significantly reduces the difficulty of operation and the need for manpower. At the same time, it also avoids the risk of the patient slipping due to the lifting action.

[0031] Specifically, the bottom of the fixed base 4 is provided with a limiting component 8, which can limit and fix the handwheel 53. By setting the limiting component 8, the position of the handwheel 53 is reliably fixed, ensuring that the fence 3 will not move accidentally during use, thus protecting the patient's safety and solving the safety hazard problem that the fence 3 may move accidentally during use.

[0032] In a further preferred embodiment, the limiting component 8 includes a threaded cylinder 81, a second threaded rod 82, a limiting rod 83, and a limiting hole 84. The threaded cylinder 81 is fixedly installed at the bottom of the fixed base 4, the second threaded rod 82 is threadedly installed inside the threaded cylinder 81, and the limiting rod 83 is fixedly installed on the side of the second threaded rod 82 near the handwheel 53. A limiting hole 84 is opened on the outer side of the handwheel 53 for the insertion of the limiting rod 83. Through the structural cooperation of the threaded cylinder 81, the second threaded rod 82, the limiting rod 83, and the limiting hole 84, the threaded cylinder 81 is welded and fixed to the bottom of the fixed base 4, and the second threaded rod 82 cooperates with it to form a helical drive. The limiting rod 83 achieves telescopic movement through thread adjustment and forms an insertion lock with the limiting hole 84 on the handwheel 53. The threaded cylinder 81 and the second threaded rod 82 have a self-locking characteristic to ensure that they will not automatically loosen under vibration or other conditions, thereby ensuring the stability of the fence 3 position.

[0033] The mobile frame 1 has a storage basket 9 inside. Two sets of U-shaped locking blocks 10 are fixedly installed on the top of the storage basket 9. The symmetrically arranged U-shaped locking blocks 10 can quickly engage the storage basket 9. By providing a detachable storage basket 9 inside the mobile frame 1, the mobile frame 1 realizes the convenient storage and retrieval function of auxiliary medical supplies, solves the problem of inconvenient storage of medical supplies, and improves work efficiency. The two U-shaped locking blocks 10 enable convenient assembly and disassembly of the storage basket 9. At the same time, the symmetrically arranged U-shaped locking blocks 10 ensure that the storage basket 9 is installed firmly.

[0034] Working principle: When using this utility model, firstly, the second threaded rod 82 is rotated, and the second threaded rod 82 moves inside the threaded cylinder 81, causing the limiting rod 83 to exit the limiting hole 84, thereby releasing the restriction on the handwheel 53. Then, by rotating the handwheel 53, the first threaded rod 51 is rotated, causing the threaded moving plate 52 to descend smoothly along the slide groove 56. The moving plate 52 drives the fence 3 to move downward through the second through hole 6. When the moving plate 52 reaches the lowest position, the top of the fence 3 is completely retracted into the groove 7 on the support frame 2. After retraction, the top surface of the fence 3 is flush with the plane of the support frame 2, forming a continuous support surface without protrusions. This solves the obstruction of the traditional fixed fence 3, allowing medical staff to more smoothly move patients to the hospital bed or operating table.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
