Detailed Description

The utility model will be further explained with reference to the embodiments of the drawings.

The lifting wheelchair for nursing shown in fig. 1 to 5 comprises a moving trolley, wherein one end of a U-shaped frame body 12 of the moving trolley is provided with a universal wheel 14, the other end of the U-shaped frame body is provided with a small wheel 11, and two sides of the U-shaped frame body 12 positioned at one side of the universal wheel 14 are symmetrically hinged with overturning pedals 13; the middle part of the U-shaped frame body 12 at one side of the small-sized wheel 11 is provided with a lifting device 9. The lifting device 9 of the embodiment comprises an inner vertical pipe 21 and an outer vertical pipe 24 sleeved outside the inner vertical pipe 21; one end of the inner vertical pipe 21 is fixed on the U-shaped frame 12, and a reinforcing rib 28 is arranged between the inner vertical pipe 21 and the U-shaped frame 12 to ensure the strength and stability of the inner vertical pipe 21. The inner vertical pipe 21 is internally provided with a nut 23 at the upper end, a screw 22 with a big bevel gear 26 is arranged on the nut 23, a thrust bearing 25 is arranged between the big bevel gear 26 and the nut 23, the big bevel gear 26 is meshed with a small bevel gear 27 arranged in the outer vertical pipe 24, and a lifting crank 6 is arranged on the leading-out shaft of the small bevel gear 27. When the lifting handle 6 is rotated forward and backward, the bevel pinion 27 is engaged with the bevel pinion 26, and the control screw 22 is rotated and lifted relative to the nut 23. A curved carrier 8 is fixed to the outer vertical tube 24, and a swivel mechanism 1 is provided on the carrier 8. The rotating mechanism 1 of the embodiment comprises a disk body 17 with a sunk groove on a bracket 8, an annular groove 19 arranged on the disk body, and a ball frame 18 arranged in the annular groove 19, wherein a seat 2 is arranged on the ball frame 18, a rotating body is formed by a disk 16 on a reinforcing belt 15 at the bottom of the seat 2 and the ball frame 18, a split semi-annular pressing ring 20 is arranged at the periphery of the disk body 17 of the bracket 8 to position the seat 2, and the disk at the bottom of the seat 2 can rotate relative to the bracket 8 to form the rotating seat. In this embodiment, to avoid free movement of the seat 2, a positioning structure 5 is provided. The positioning mechanism 5 comprises a chair back of the chair 2, wherein an arc rib plate 3 is arranged on the chair back of the chair 2, a groove-shaped socket 34 is arranged in the middle of the arc rib plate 3, a plug board 31 and a handle 35 arranged on the plug board are arranged in the groove-shaped socket 34, a strip-shaped hole 32 is formed in the plug board 31, the plug board 31 is matched with a positioning pin 33 on the groove-shaped socket 34 through the strip-shaped hole 32 and can move up and down along the positioning pin 33, and the plug board 31 is inserted into a positioning mechanism formed by matching with a plug bush 7 on a lifting device.
