Description
Technical field
The present invention relates to it is a kind of can stair activity manual wheelchair, belong to manual wheelchair technical field.
Background technology
It is existing can the wheelchair of stair activity be mostly electric drive, electrically driven (operated) wheelchair stair activity is although laborsaving, but wheel
Chair is heavier in itself, again concern charging, using cumbersome.And it is existing can the crawler belt groove that uses of wheelchair of stair activity do not show
Write, be only suitable in level land or hillside fields walking, general stair are all relatively steeper, during stair activity, especially go downstairs, due to crawler belt
Groove does not cause that wheelchair is easily out of control, is generally required for the personnel of unsoundness to accompany significantly, to avoid causing taking wheelchair person's
Personal injury.
The content of the invention
The invention aims to solve the problem of above-mentioned prior art is present, so provide it is a kind of can stair activity
Manual wheelchair.
The purpose of the present invention is achieved through the following technical solutions：
It is a kind of can stair activity manual wheelchair, including：Handwheel, wheel, vehicle frame, gesture stability bar, sheath, front gear,
Chain, forward pass moving gear, driven gear, final drive gear, rubber strip, support bar, backgear, driving gear, driving gear shaft
And main shaft, the main shaft is fixed on the lower end at vehicle frame rear portion, and driving gear shaft is fixed on the vehicle frame on main shaft top, handwheel, car
Wheel and driving gear are coaxially mounted on driving gear shaft, and driven gear is arranged on main shaft, and driven gear and driving gear are nibbled
Close, front gear, forward pass moving gear, driven gear, final drive gear and backgear are sequentially arranged on support bar, driven gear point
Do not engaged with forward pass moving gear and final drive gear, forward pass moving gear is engaged with front gear, and final drive gear is engaged with backgear,
Connected between front gear and backgear by chain drive, chain is provided with rubber strip, sheath is fixed on the top of vehicle frame, posture control
The lower end of bar processed is connected with the gear shaft of front gear, and the upper end of gesture stability bar is arranged in sheath.
The cross section of the rubber strip is rectangle, and the spacing distance of two rubber strips is the width of a rubber strip.
The power of the present invention comes from the people oneself for taking wheelchair, usually, and the people for taking wheelchair rotates handwheel, handwheel with hand
Vehicle wheel rotation is driven to realize the walking on level land, now handwheel also drives driving gear to rotate, driving gear drives passive tooth rotation
Dynamic, driven gear drives forward pass moving gear and final drive gear to rotate, and driving front gear drives front gear to rotate, final drive gear
Drive backgear to rotate, front gear and backgear drive chain to rotate, above-mentioned all rotations be all it is synchronous, equidirectional,
Simply dally, crawler belt is now that horizontality is micro- from the ground, wheelchair is walked if road injustice crawler belt can also land.It is upper to go downstairs
When terraced, gesture stability bar only need to be manipulated, makes crawler belt updip or has a down dip, because the cross section of rubber strip is rectangle, two rubber
The spacing distance of band is on the width of rubber strip, the angle that can be stuck in each step of stair so that stair activity is steadily pacified
Entirely.
