Description

The patient's wheelchair that can go upstairs

Technical field

This utility model relates to a kind of medical apparatus and instruments, particularly a kind of patient's wheelchair that can go upstairs.

Background technology

Traditional patient's wheelchair is generally made up of four wheels, can only adapt to walk on level ground, can not upstairs, can wheelchair upstairs although have, and is generally all DYN dynamic, its structure is very complicated, and cost is very high, can not popularize to common patient.

Summary of the invention

Can not upstairs in order to overcome traditional push chairs, and electrodynamic type Wheelchair structure is complicated, the defect that cost is higher, this utility model provides a kind of patient's wheelchair that can go upstairs,

The technical scheme in the invention for solving the technical problem is: a kind of patient's wheelchair that can go upstairs, it comprises: chair lower limb, handrail, it is characterized in that: in each chair lower limb, a universal drive shaft is vertically set respectively, two bearings are set respectively between each universal drive shaft and chair lower limb, U-shaped fork is set the lower end of each universal drive shaft is oblique respectively, the lower end pitched at each U-shaped is horizontally disposed with a main shaft, each main shaft vertically arranges two corresponding triangle forks respectively, the end pitched at each triangle is horizontally disposed with a countershaft respectively, each countershaft arranges a roller respectively, and the activity of chair two handrail upper levels arrange one can extract out after handle, a hollow bushing is horizontally disposed with respectively in chair two handrail bottoms, in each hollow bushing, level of activation arranges a front handlebar that can extract out respectively.

The aforesaid patient's wheelchair that can go upstairs, it is characterized in that: hollow bushing front opening, two front handlebars are movably set in hollow bushing respectively, two front handlebars can be extracted out.

The aforesaid patient's wheelchair that can go upstairs, is characterized in that: after two, handle is arranged at the rear portion of chair.

The aforesaid patient's wheelchair that can go upstairs, is characterized in that: after two, the position of handle is higher than the position of two front handlebars.

The aforesaid patient's wheelchair that can go upstairs, is characterized in that: after two, handle can be extracted out from handrail rear portion.

When front handlebar, rear handle are used for going upstairs, patient is carried on stair; Chair lower limb is hollow bushing, and universal drive shaft, bearing, U-shaped fork can 360 degree of rotations in chair lower limb, for auto-steering.

The beneficial effects of the utility model are: both can walk on a horizontal ground, can go upstairs again, and structure is simple, easy to use.
