The connecting assembly 7 forms a flexible and stable connection structure through the combination of the connecting post 701, the connecting rod 703 and the connecting rod 704. The rotating ball 705 is rotated inside the mounting base 5, so that the connecting assembly 7 can adapt to the needs of different angles.
[0034] Please refer to Figure 4As shown, the transfer assembly 8 is fixed on the mounting sleeve 706. The transfer assembly 8 includes a mounting box 801, the left side of which is fixedly connected to one side of the mounting sleeve 706. Limiting blocks 803 are fixedly connected to both the upper and lower sides inside the mounting box 801. Limiting grooves 804 are formed inside both sets of limiting blocks 803, and the openings of the two sets of limiting grooves 804 face opposite directions.
[0035] Please refer to Figure 4 As shown, both sets of limiting slide grooves 804 are slidably connected to sliding strips 805, and both sets of limiting slide grooves 804 are fixedly connected to limiting rods 811. The two limiting rods 811 are slidably connected to the inside of the two sets of sliding strips 805 respectively. Both sets of sliding strips 805 are fixedly connected to a transfer block 807 on the side away from the mounting box 801. A gear 802 is rotatably connected in the middle of the inside of the mounting box 801.
[0036] Please refer to Figure 4 As shown, racks 806 are fixedly connected to the sides of the two sets of sliding bars 805 that are close to each other. Gear 802 meshes with rack 806. A reducer 810 is fixedly connected to the side of the mounting box 801 that is close to the connecting component 7. The output end of the reducer 810 passes through the side wall of the mounting box 801 and is fixedly connected to the left end of gear 802. The reducer 810 adopts a worm gear type and has a self-locking function.
[0037] Please refer to Figure 4 As shown, support blocks 808 are fixedly connected to both the front and rear sides of the installation box 801. Support rods 809 are slidably connected inside the two sets of support blocks 808. The ends of the two support rods 809 are fixedly connected to the sides of the two sets of transfer blocks 807 respectively. The meshing of gear 802 and rack 806, as well as the drive of reducer 810, enable the transfer blocks 807 to move smoothly and accurately. This design not only improves the automation level of the equipment, but also increases the convenience of use. At the same time, the design of support blocks 808 and support rods 809 enhances the stability of transfer blocks 807 and ensures safety during the process of supporting patients.
[0038] Please refer to Figure 4 As shown, the transfer block 807 is made of polyethylene, polypropylene, polycarbonate, polystyrene, or polyoxymethylene.
[0039] Working principle: First, the device is installed on the side of the wheelchair backrest via the connecting base 101. During transfer, the device is connected to the mains power via the terminal 702. The first locking ring 4 is loosened, the telescopic rod 3 is pulled out from the telescopic sleeve 2, and the transfer assembly 8 is adjusted to a suitable height. Then, the first locking ring 4 is rotated to lock it. Next, the reducer 810 drives the gear 802 to rotate. Through the meshing relationship with the rack 806, the sliding bars 805 on both sides drive the two transfer blocks 807 to move away from each other, thereby adjusting to a distance suitable for the width of the patient's shoulders. Then, the two transfer blocks 807 are placed under the patient's armpits. Then, the medical staff helps the patient up and transfers him to the wheelchair. During the transfer, the rotating ball 705 will rotate inside the mounting base 5 to adapt to the transfer assembly 8 during the transfer process. The rotating column 104 rotates inside the mounting column 103, and the rotating seat 102 rotates above the connecting base 101. The above-mentioned two-axis rotation can also adapt to the different angle changes of the transfer component 8 during the transfer process. When the patient is placed on the wheelchair, since the length of the combination of the telescopic rod 3 and the telescopic sleeve 2 is too long, it is only necessary to slightly loosen the first locking ring 4 so that the telescopic rod 3 and the telescopic sleeve 2 are not locked tightly. As the patient sits on the wheelchair, the telescopic rod 3 gradually retracts into the telescopic sleeve 2. Then the transfer component 8 is pulled out from under the patient's armpit. The reducer 810 drives the gear 802 to rotate in the opposite direction, so that the two transfer blocks 807 return to their original positions. Then the transfer component 8 and the connecting component 7 are folded and stored on the side of the wheelchair.
[0040] In another embodiment, the transfer component 8 is a flat plate fixed to the mounting sleeve 706. During transfer, the flat plate is placed on the hospital bed, and the patient's buttocks rest on the flat plate to support the body. Then, the patient is slowly moved between the wheelchair and the hospital bed to achieve the transfer.
[0041] The above embodiments are not an exhaustive list based on the present invention, and there may be many other embodiments not listed. Any substitutions and improvements made without departing from the concept of the present invention are within the protection scope of the present invention.
