Screw togather.And loss of weight support block 511 is connected to the top of steel shaft 509, top surface contact wheelchair 700 bottom of loss of weight support block 511
Wheelchair support bar two ends.Loss of weight support block 511 includes two limiting side walls 5111 and between limiting side wall 5111
Support slot 5112.Limiting side wall 5111 can also stop that wheelchair 700 is skidded off in training to the guiding slope 101 of base 100.
Figure 17 is the use schematic diagram of the decline state of the middle weight reducing device of wheelchair training system of the present utility model.Figure 18
For the sectional view of the decline state of the middle weight reducing device of wheelchair training system of the present utility model.As shown in FIG. 17 and 18, when inverse
During hour hands rotary fine adjustment disk 510, T-shaped thread barrel 507, limited block 503 also rotate counterclockwise；Due to clutch shaft bearing 504 and
Two bearings 508, inner cylinder 506 are fixed on fixed cylinder 505, and fixed cylinder 505 is connected to connection nahlock 502, fixed plate 501
On, so during fine setting disk 510, when T-shaped thread barrel 507,503 rotate counterclockwise of limited block, will not move up and down；Due to steel shaft
509 are threadedly coupled with T-shaped thread barrel 507, and when T-shaped 507 rotate counterclockwise of thread barrel, steel shaft 509 is moved down, while steel shaft
509 also drive loss of weight support block 511 to move down.
Figure 19 is the use schematic diagram of the propradation of the middle weight reducing device of wheelchair training system of the present utility model.Figure 20
For the sectional view of the propradation of the middle weight reducing device of wheelchair training system of the present utility model.As shown in Figures 19 and 20, when suitable
During hour hands rotary fine adjustment disk 510, T-shaped thread barrel 507, limited block 503 also turn clockwise；Due to clutch shaft bearing 504 and
Two bearings 508, inner cylinder 506 are fixed on fixed cylinder 505, and fixed cylinder 505 is connected to connection nahlock 502, fixed plate 501
On, so during fine setting disk 510, when T-shaped thread barrel 507, limited block 503 turn clockwise, will not move up and down；Due to steel shaft
509 are threadedly coupled with T-shaped thread barrel 507, and when T-shaped thread barrel 507 turns clockwise, steel shaft 509 is moved up, while steel shaft
509 also drive loss of weight support block 511 to move up.By taking the first backing roll 104 as an example, the present embodiment includes left and right two section
One backing roll 104, this two section of first backing roll 104 each supports two wheels of wheelchair 700, because user may wear vacation
Limb or part of limb is lost, so, two section of first backing roll 104 may not phase to the support force of two wheels of wheelchair 700
Together, this can cause the load of wherein one section first backing roll 104 to lay particular stress on, and in the case of long-term rotation, can destroy two section first
The axiality of backing roll 104, easily affects the life-span of wheelchair training system, can also allow user to think that wheelchair is to wheelchair training
The side of system inclines, and causes unilateral frictional force excessive, so, the weight reducing device in this utility model can be directed to heavier one
Side, rises certain altitude, and a part of load is undertaken by weight reducing device, keeps wheelchair in the horizontal position of wheelchair training system
Put so that two section of first backing roll 104 is identical to the support force of two wheels of wheelchair 700, so as to improve Consumer's Experience,
Extend life of product.
In a variation, when user rolls the wheel of wheelchair 700, the wheel of wheelchair 700 and the first backing roll
104 extruding is less, and frictional force is less, and weight loss effect is more obvious；When the wheel of wheelchair 700 is not contacted with the first backing roll 104
When, preferably, now, the wheel of wheelchair 700 is only contacted the weight loss effect of weight reducing device 500 with the second backing roll 105.
This utility model also includes display device 600, and display device 600 includes：One display screen 601, a keyboard 602 and
Support bar 603.Support bar 603 is arranged on the second end of base 100.Display screen 601 is connected to support bar 603.And keyboard 602
It is connected to support bar 603.
Figure 21 is the schematic diagram of the use state of wheelchair training system of the present utility model.Figure 22 is wheel of the present utility model
Chair training system removes the schematic diagram of the use state after the wall of side.As shown in figs. 21 and 22, wheelchair training system of the present utility model
The use process of system is as follows, and first wheelchair 700 enters base 100 by guiding slope 101, then by lowering or hoisting gear 200
Swingle 201 puts down hoistable platform 206, makes the first support roller 104, the second support roller 105 and weight reducing device 500 support wheelchair
700, the damping that user can change the first support roller 104 by adjustable damping component is strong and weak, in wheelchair training system
Carry out wheelchair uses training.
In summary, gear adjusting device of the present utility model, adjustable damping component and wheelchair training system can be conveniently
Carry out gear regulation, and it is whole in wheelchair training accompany without the need for nurse, safely can may be used completely by user independent operation
Lean on, practicality is high.
The above is only concrete application example of the present utility model, any limit is not constituted to protection domain of the present utility model
System.In addition to the implementation, this utility model can also have other embodiment.All employing equivalents or equivalent transformation are formed
Technical scheme, all fall within this utility model it is claimed within the scope of.
