Detailed Description

The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings, it being understood that the preferred embodiments described herein are for illustration and explanation of the present utility model only, and are not intended to limit the present utility model.

Examples: as shown in fig. 1-4, the utility model relates to a wheelchair plastic foot rest lifting mechanism, which comprises a roll-over stand 1, wherein a partition board frame 2 which is obliquely arranged is arranged at the outer end part of the roll-over stand 1, a footrest 3 is arranged on the partition board frame 2, the inner end part of the roll-over stand 1 is hinged with a wheelchair main body frame 13 through a hinge piece 4, a hinge block 5 is arranged on the partition board frame 2, a positioning block 6 is arranged on the wheelchair main body frame 13, a telescopic push rod 7 is arranged between the positioning block 6 and the hinge block 5, and the footrest 3 is made of plastic materials; the lifting height of the baffle frame 2 is controlled by controlling the telescopic push rod 7, and the telescopic degree of the telescopic push rod 7 can be controlled when the wheelchair is up and down, so that the roll-over stand 1 can be turned inwards to be stored without colliding with legs of a human body.

The hinge 4 comprises a positioning block I8 which is welded with a wheelchair main body frame 13 into a whole, a positioning shaft 9 which is transversely arranged on the positioning block I8, a through hole 10 through which the positioning shaft 9 passes is formed in the roll-over stand 1, and the end part of the positioning shaft 9 passes through the through hole 10 and is provided with a limiting block 11, so that the installation is convenient.

The telescopic push rod 7 is an electric telescopic push rod and has the characteristic of easy control.
