[0050] Preferably, the transfer device further comprises the handrail 7, which is arranged at the two sides of the stretcher 2 and is fixedly connected with the main beam 1 at the two ends, for being gripped by the patient and the user.

[0051] Referring to Figure 4 , 5 , 6:

[0052] Preferably, the pressing rotary lock 5 comprises the lock seat and the lock core 501 fixedly connected with the support arm 3;

[0053] The main beam 1 is fixedly connected with the lock seat 504a at the first working position of the support arm 3 and is fixedly connected with the lock seat 504b at the second working position, the lock core 501 is internally provided with the limiting pin 502 capable of being extended and retracted, the lock handle 503 is arranged at the top end of the lock core 501, the lock handle 503 is connected with the limiting pin 502, and in use, the lock handle 503 is pressed and rotated to drive the limiting pin 502 to be locked or separated from the lock hole 505 on the lock seat 504;

[0060] In the above technical solution, the present invention provides a low-profile, liftable transfer device, the method of use of which is as follows:

[0061] The operator pushes the entire device into the ward using the stretcher 2 and handrail 7. Upon reaching the bedside, the operator presses and rotates the locking mechanism 5 clockwise to unlock it, while simultaneously changing the support arm 3 from the first working position to the second working position (e.g., Figure 2 As shown), rotate the press lock 5 counterclockwise and release it to lock the support arm 3, thus locking the lifting leg 4. Then, through the controller connected to the control system, the lifting leg 4 is raised to a height that can cross the hospital bed. The operator moves the stretcher 2 to a position directly above the patient using the handrail 7. The operator controls the latch 6 to unlock the two stretchers 2 and pulls the stretchers 2 to both sides through the slide rail 201. The lifting leg 4 is lowered to the level of the patient's back using the controller. The patient is placed on the stretcher 2, the two stretchers 2 are pushed back, and the latch 6 is used for self-locking. The lifting leg 4 is raised using the controller, and the device is pulled out above the hospital bed, thus realizing the transfer process.

[0062] Working principle of press-lock 5:

[0063] See Figure 4 , 5As shown in Figure 6, the support arm 3 is fixed to the main crossbeam 1 via the central shaft 301. By pressing and rotating the lock handle 503 of the press lock 5 clockwise, the limiting pin 502 of the lock cylinder 501 inside the press lock 5 is disengaged from the lock hole 505 in the lock seat 504a. Pressing the lock 5 unlocks the support arm 3, which can cause the support arm 3 to drive the lifting leg 4 to rotate around the central shaft 301. When the support arm 3 is aligned with the lock seat 504b, pressing and rotating the lock handle 503 counterclockwise causes the internal limiting pin 502 to engage in the lock hole 505 of the lock seat 504b, thereby achieving self-locking and locking the support arm 3.

[0064] Working principle of the 6-pump lock:

[0065] See Figure 2 , 7 As shown in Figure 8, since the slide rail 201, stretcher 2, latch 6, and locking post 606 are symmetrically arranged, taking the adjustment of one stretcher 2 as an example, when the stretcher 2 is pushed, the stretcher 2 always remains in contact with the switch 603 of the latch 6. When the slide rail 201 retracts and the stretcher 2 is closed, the switch 603 disengages from the stretcher 2 and resets. At this time, the locking post 606 is engaged in the limiting groove 604 of the latch 6, and the limiting groove 604 locks the stretcher 2. When the two stretchers 2 are separated, the handle 605 on the switch 603 of the latch 6 is moved, causing the locking post 606 of the stretcher 2 to pop out of the limiting groove 604 of the latch 6, and the stretcher 2 is unlocked.

[0066] Beneficial effects: This low-profile, liftable transfer device is suitable for transfer in various scenarios. It has a compact structure, occupies little space, and is easy to operate. In addition, many functional points have mechanical self-locking structures, which improves the overall safety of the transfer device.
