DETAILED DESCRIPTION
[0035] The following is a specific embodiment of the utility model and further describes the technical method of the utility model in combination with the drawings, but the utility model is not limited to these embodiments.
[0036] As Figures 1-4 shown, the utility model provides a transfer device suitable for air pressurized oxygen cabin, comprising:
[0037] The seat 100 has a main driving wheel 110 and a climbing wheel 120, the main driving wheel 110 is installed at the rear wheel position of the seat 100, and the climbing wheel 120 is installed at the front wheel position of the seat 100.
[0038] The climbing wheel 120 comprises a connecting plate 121 and a plurality of secondary driving wheels 122, the connecting plate 121 is rotatably installed at the front wheel position of the seat 100 through a rotating shaft, and each secondary driving wheel 122 is equidistantly distributed on the connecting plate 121.
[0039] The number of the secondary driving wheels 122 is at least three, when the seat 100 runs on a flat road, at least two secondary driving wheels 122 are in contact with the ground and rotate by themselves, providing smooth running.
[0040] When the seat 100 needs to cross the threshold, each secondary driving wheel 122 revolves around the rotating shaft of the connecting plate 121 and crosses the threshold.
[0041] It should be noted that the 10cm high threshold of the current GY2200 medical air pressure oxygen cabin causes inconvenience for patients to enter and exit, especially for patients who cannot move independently. The traditional method requires medical staff to manually lift the patient in and out of the oxygen cabin, which not only increases the discomfort of the patient, but also may cause accidental falling due to improper operation.
[0042] To solve the above problems, the transfer device provided in the embodiment designs the structure of the climbing wheel 120, which integrates the functions of flat road running and threshold crossing, and only needs the medical staff to push the seat 100 forward to automatically realize the switching between flat road running and threshold crossing, without the need for additional design of a specific function switching structure, which is more convenient to apply.
[0043] In addition, the setting of the transfer device no longer requires medical staff to manually lift the patient in and out of the oxygen cabin, which is more labor-saving and also avoids the risk of accidental falling of the patient due to the height limitation of the cabin door when manually lifting the patient, ensuring the safety of the patient.
[0044] Preferably, the bottom of the seat 100 is provided with a front support 130 and a rear support 140, the main driving wheel 110 is arranged at the end of the rear support 140, and the climbing wheel 120 is arranged at the end of the front support 130.
[0045] Further, the end of the front support 130 away from the climbing wheel 120 is rotatably connected to the bottom of the seat 100, so that when crossing the threshold, not only can each secondary running wheel 122 revolve around the rotation shaft of the connecting plate 121, but the connecting plate 121 can also move with the up-and-down rotation of the front support 130;
[0046] This means that when encountering a threshold, the front support 130 can automatically adjust its inclination angle according to the height of the obstacle, so that the climbing wheel 120 can more flexibly adapt to thresholds of different heights. This double rotation mechanism (the revolution of the secondary running wheel 122 and the overall rotation of the connecting plate 121 with the front support 130) ensures that the climbing wheel 120 can more smoothly cross the obstacle, thereby improving the overall device's passing ability in complex environments.
[0047] Preferably, it further comprises a connecting shell 123, and the climbing wheel 120 is connected to the front support 130 through the connecting shell 123, and the center position of the connecting plate 121 is connected to the front support 130 through a rotation shaft.
[0048] Further, in order to improve the stability and comfort when crossing the threshold, a buffer structure is provided between the connecting shell 123 and the front support 130, and the buffer structure comprises:
[0049] A connecting block 124 is hingedly connected to the end of the front support 130 to allow for some angle adjustment;
[0050] A damper 125 and a spring 126 are connected between the connecting block 124 and the connecting shell 123 through the damper 125, which provides resistance to smooth the vibration and impact during movement, while the spring 126 is sleeved outside the damper 125 and the two ends of the spring 126 are respectively abutted with the connecting block 124 and the connecting shell 123, which plays a role in shock absorption and rebound, thereby ensuring that the entire transfer device can more smoothly transition when encountering obstacles, reducing the jolt and reducing the patient's discomfort.
[0051] Preferably, the seat 100 has a backrest 150, and the top end of the backrest 150 is provided with an armrest 160, which facilitates medical staff to grasp and push the seat 100, thereby enhancing the safety and convenience during use and saving labor.
[0052] Preferably, the backrest 150 is provided with an angle adjustment mechanism, and the angle adjustment mechanism comprises a rotation shaft 170 connected to the backrest 150, which drives the backrest 150 to rotate to adjust its angle through the rotation of the rotation shaft 170, so that the patient can adjust to the most comfortable body posture, thereby improving the comfort of the patient.
[0053] Specifically, the angle adjustment mechanism further comprises:
[0054] A sliding plate 180 movably arranged on the slide groove 190 formed on the side of the seat 100, and a rack 181 arranged on the sliding plate 180;
[0055] A first gear 200 engaged with the rack 181 and a second gear 210 engaged with the first gear 200, and the second gear 210 connected with the rotating shaft 170;
[0056] That is, when the sliding plate 180 moves linearly along the slide groove 190 formed on the side of the seat 100, the rack 181 arranged on the sliding plate 180 moves linearly synchronously, and the movement of the rack 181 drives the first gear 200 and the second gear 210 to rotate in sequence, and the rotating shaft 170 connected with the second gear 210 rotates to adjust the angle of the backrest 150.
[0057] The gear transmission system ensures the stability of the entire adjustment process, avoids the possible problems of slipping or position deviation, and ensures the accuracy of the angle adjustment of the backrest 150.
[0058] In addition, the angle adjustment mechanism further comprises a locking structure. Specifically, a limiting block 220 is arranged at the bottom of the sliding plate 180, the limiting block 220 is provided with a insertion hole 221, and the side surface of the slide groove 190 is provided with a plurality of limiting holes 191 arranged in a straight line. When the insertion hole 221 is aligned with a certain limiting hole 191, the bolt 222 is inserted into the insertion hole 221 and the limiting hole 191 to limit the movement of the sliding plate 180, thereby locking the sliding plate 180, and vice versa.
[0059] The specific adjustment method of the backrest 150 is as follows:
[0060] 1. Remove the limiting of the sliding plate 180: pull out the bolt 222 from the insertion hole 221 and the limiting hole 191, and after pulling out the insertion, the sliding plate 180 is in a movable state in the slide groove 190, and the sliding plate 180 is moved along the slide groove 190 by manually pushing or pulling the sliding plate 180;
[0061] 2. Gear and rack 181 transmission: as the sliding plate 180 moves along the slide groove 190, the rack 181 on the surface of the sliding plate 180 drives the first gear 200 to rotate, and the first gear 200 drives the second gear 210 to rotate, and at this time the rotation of the second gear 210 drives the rotating shaft 170 to rotate, thereby adjusting the angle of the backrest 150;
[0062] 3. Locking of the backrest 150: after the backrest 150 is adjusted to the appropriate angle, the bolt 222 is inserted into the corresponding insertion hole 221 and limiting hole 191, thereby locking the sliding plate 180 and further locking the backrest 150.
