[0034] The stretcher outer frame 1 serves as the basis of the transport device, and the transport switching mechanism 2 can be used to adjust the overall height of the transport device, so that the device can be changed from a pushing state to a hand-lift stretcher state, which is convenient for use in different states. At the same time, the stretcher seat switching mechanism 3 can be used to transform the transport device in a lying state into a seat structure, thereby improving the use effect of the transport device.

[0035] See also Figure 4-5 In the embodiment of the present invention, the transport switching mechanism 2 is composed of a main leg 21, a universal wheel 22, a sleeve 23, a cross arm 24, a sleeve 25, an auxiliary leg 26, an auxiliary leg 27, a locking piece 28, a square plate 29, and a universal wheel 210, wherein the main leg 21 includes four, which are respectively hinged to the bottom two sides of the stretcher outer frame 1. The transport device is mainly supported by the four main legs 21 under normal conditions. Since the length of the main legs 21 is longer than the auxiliary legs, the transport device maintains the highest structure under normal conditions. The universal wheel 22 is fixedly connected to the bottom outer wall of the main leg 21 by screws, and is used to adjust the moving direction of the transport device. The universal wheel 22 will fit the ground for sliding under normal conditions. The sleeve 23 is fixedly connected to the outer walls of the four main legs 21, and a cross arm 24 is inserted between the two sleeves 23 on the left and right sides. The cross arm 24 is disposed between the two main legs 21 , ensuring that the distance between the two main legs 21 always remains fixed, thereby helping to improve the overall stability of the device.

[0036] The sleeve 25 is fixedly connected to the outer wall of the four main legs 21, and the sleeve 25 is located at the top of the sleeve 1 23. The auxiliary legs 1 26 and the auxiliary legs 27 are respectively inserted into the inner wall of the sleeve 25 on the left and right sides. The auxiliary legs 1 26 and the auxiliary legs 2 27 are used as auxiliary support members, and can support the entire conveying device through the four auxiliary legs after the main legs 21 are rotated. The locking member 28 is installed between the auxiliary legs 1 26 and the auxiliary legs 2 27 to fix the main legs 21 to prevent them from shaking. The locking member 28 plays the role of connecting the auxiliary legs 1 26 and the auxiliary legs 2 27 when they are combined. After the locking member 28 is separated, the auxiliary legs 1 26 and the auxiliary legs 2 27 can be rotated at will to lower the height of the conveying device. Universal wheel 210 is fixedly connected to the outer wall of one end of auxiliary leg 1 26 and auxiliary leg 2 27 by screws. When main leg 21 and auxiliary leg 1 26 and auxiliary leg 2 27 are flipped at the same time, universal wheel 210 can be rotated to the ground to adjust the moving direction of the conveying device.

[0037] In the transport switching mechanism 2, the locking member 28 can be used to fix the main leg 21 to prevent it from shaking, so that the entire transport device can be kept in a high position, which is convenient for medical staff to push. When the locking member 28 is unfolded to separate the main leg 21, the main leg 21 can be rotated to drive the universal wheel 210 to flip to fit the ground. While lowering the transport device to lift it, the universal wheel 210 can also be used to slide on the ground to save physical energy.

[0038] See also Figure 6 In the embodiment of the present invention, the stretcher seat switching mechanism 3 includes a folding member 31 arranged inside the stretcher outer frame 1, wherein the folding member 31 is divided into two groups, symmetrically distributed front and back, and a pad member 32 for the patient to lie down, and the pad member 32 is fixedly connected to the inner wall of the folding member 31, a connecting rod member 33 installed at the bottom of the folding member 31, and a driving member 34 arranged on one side of the stretcher outer frame 1 for adjusting the inclination angle of the folding member 31 and the pad member 32.

[0039] In the stretcher seat switching mechanism 3, under the action of the driving member 34, by selecting the rotating handle 1 343 or the rotating handle 2 344 to rotate the worm 342, the worm wheel 341 can be controlled to rotate, and then the cushion 321 can be controlled to rotate along the axis of the worm wheel 341 as the center of the circle. On this basis, the driving rod 332 and the passive rod 333 will move a distance along the inner wall of the track 331, thereby driving the leg pad 323 to tilt, and the patient can change from a lying state to a sitting state, which helps the patient to adjust the sitting posture to improve the comfort during transportation when it is impossible to lie down or it is inconvenient to lie down.

[0040] See also Figure 7-10In the embodiment of the present invention, the locking member 28 is composed of a semi-cylinder 1 281, a semi-cylinder 282, a fixing sleeve 283, a ball column 284, a spring 285, an arc groove 286, and a limiting hole 287, wherein the semi-cylinder 1 281 and the semi-cylinder 2 282 are respectively fixedly connected to the outer wall of one end of the auxiliary leg 1 26 and the auxiliary leg 2 27, and the semi-cylinder 1 281 and the semi-cylinder 2 282 form a cylindrical structure embedded together.

A limiting hole 287 is provided on the plane side of the semi-cylinder 282, and the ball column 284 is tightly attached to the inner wall of the limiting hole 287. When the auxiliary support leg 1 26 and the auxiliary support leg 2 27 approach each other, the ball column 284 and the arc block on the semi-cylinder 1 281 will slide along the inner wall of the arc groove 286 of the semi-cylinder 282. At this time, the spring 285 is in a compressed state. Since a limiting hole 287 is opened in one of the arc grooves 286, when the ball column 284 approaches the limiting hole 287, the spring 285 is reset and the ball column 284 will move into the limiting hole 287. At this time, the semi-cylinder 1 281 and the semi-cylinder 2 282 will be combined together. In the absence of a large external force, the semi-cylinder 1 281 and the semi-cylinder 2 282 will not be able to be separated.

When the patient is unable to lie down or it is inconvenient to lie down, the patient turns the rotating handle 1 343 or the rotating handle 2 344 to drive the worm 342 to rotate, thereby controlling the rotation of the worm gear 341, and then controlling the rotation of the back cushion 321. The head connecting rod 311 can rotate along the axis of one end connection of the leg connecting rod 313 as the center of the circle, and the leg connecting rod 313 can rotate along the axis of the other end connection of the leg connecting rod 313 as the center of the circle. When the driving rod 332 changes its position, the back cushion 321 will also change its folding angle accordingly. Since the passive rod 333 is connected to the driving rod 332, the passive rod 333 will also change its position along the inner wall of the track 331, and the leg pad 323 will also change its folding angle accordingly. The above process transforms the transport device in a lying state into a seat structure.
