Embodiment
A kind of servicing unit suitable for common wheelchair motorized, as shown in figure 1, including wheelchair 4, single wheel mechanism of car 3 and
Bindiny mechanism 2, the fixed mechanism 1 are fixed in the frame of wheelchair 4, that is, two frame vertical bars of wheelchair front end
On 401, the bindiny mechanism 2 is used for be connected mechanism 1 and single wheel mechanism of car 3.
Shown in the structure of fixed mechanism 1 such as Fig. 2 (a), Fig. 2 (b) and Fig. 3 (a), Fig. 3 (b), ratchet 105 is arranged on left outside shell
102 inner chamber, its one end are fixed by the shaft shoulder, and the other end is fixed by end cap 106, and the end cap 106 is existed by screw lock
On left outside shell 102, ratchet shaft 103 realizes axially position by screw lock on end cap 106, and the rotation of ratchet shaft 103 passes through
General flat key 107 passes to ratchet 105.Installation handle 104 uses screw lock after putting square toes holding screw 108, installs hand
Handle 104, which rotates, drives square toes holding screw 108 to rotate, so as to lock the connecting rod 201 of bindiny mechanism.The one end of square toes long spiro nail 110
It is connected through a screw thread with wedge 112, the other end uses screw lock after putting reversing handle 109, is needed before installing wedge 112
Spring 111 is arranged in the rectangular channel between wedge 112 and left outside shell 102, reversing handle 109 controls wedge
Position and then the unidirectional or Double-directional rotary for controlling ratchet.
Bindiny mechanism 2 is as shown in figure 4, the bindiny mechanism 2 includes connecting rod 201, gripping block 203, dovetails 202 and dovetail
Groove 204, connecting rod 201 is arranged in the circular hole of dovetails 202, through square toes holding screw 108 after width adjusting to suitable position
Fixed, the gripping block 203 has two pieces, and two pieces of left and right fits together, and is fixed on the pole of single wheel mechanism of car 3, one end leads to
Cross and fixed through bolt and nut component, the other end can be fixed on dovetail groove 204 by bolt and nut component, realize bindiny mechanism
2 with the handling of single wheel mechanism of car 3.
The connecting rod 201 is U-shaped bar, and middle transverse rod passes through the circular hole of dovetails 202, and two frame vertical bars 401 are with consolidating
Determine the ratchet shaft of mechanism 1 through hole suitably adjust longitudinal separation after, screw connecting rod 201 by installing handle 104 and be fixed on
In the through hole of ratchet shaft 103.After connecting rod 201 is fixed, reversing handle 109 is set to be in Fig. 2 (a) position, now wedge 112 exists
The effect of spring 111 is lower with the surface engagement of ratchet 105, and ratchet 105 is limited by wedge 112 and one-directional rotation and can only realized certainly
Lock, promoting the handle of single wheel mechanism of car can be such that connecting rod 201 is rotated under the effect of ratchet 105, adjust the angle of wheelchair, make wheelchair
Wheelie certain distance from the ground.And left outside shell is placed on, it is necessary to up lift 90 ° of rotatable handle when unloading bindiny mechanism 2
On 102 boss, wedge 112 is moved upwards with handle, departs from the surface of ratchet 105, and ratchet 105 can be taken turns with Double-directional rotary
Front-wheel recovers to contact with ground chair under gravity, after rotation installation handle 104 unclamps holding screw, the company of bindiny mechanism 2
Bar 201 can unload from the through hole of ratchet shaft 103.
Bindiny mechanism 2 and single wheel mechanism of car 3 and connection it is as shown in Figure 6.Two gripping blocks 203 are fixed on single wheel mechanism of car
Pole 301 on, one end is locked using bolt and nut component, and the other end is connected simultaneously using bolt and nut component with dovetail groove 204
Locking, dovetail block assembly 202 realize the company of bindiny mechanism 2 and single wheel mechanism of car 3 by being connected with dovetail groove 204
Connect.
As shown in Figures 5 and 6, when being applied to the servicing unit of common wheelchair motorized using the present invention, first dovetail
Groove 204 is by gripping block 203, bolt and nut component and is fixed on the pole 301 of single wheel mechanism of car 3, then fixed mechanism 1 is led to
Cross right casing 101, left outside shell 102 and trip bolt to be fixed in wheelchair frame vertical bar 401, finally dovetails 202 are installed
To dovetail groove 204, connecting rod 201 is installed to the through hole of ratchet shaft 103, and square toes holding screw 108 is screwed using installation handle 104
Fixed connecting rod 201, that is, complete installation of the present invention.After installation, wheelchair 4 is under the dynamic action that single wheel mechanism of car 3 provides
Straight line and curvilinear motion can be realized, is provided convenience for disabled person's trip, is reduced wheelchair and realize electronic cost.Wheelchair makes
After, it is only necessary to unload lower link 201 from fixed mechanism 1, dovetails 202 are unloaded from dovetail groove 204, you can wheelchair 4, even
Connection mechanism 2, single wheel mechanism of car 3 separate, and are easy to the storage of wheelchair when not in use, can also recover wheelchair 4 function of itself.
The present invention is the servicing unit installed additional on the basis of common wheelchair, installation and removal it is convenient and swift, simple in construction,
Stable connection applicability is wide, by the present invention single wheel mechanism of car can be made to be connected with wheelchair, drives wheelchair to carry out straight line and curve fortune
Dynamic, the crowd for trip inconvenience provides convenience, and reduces wheelchair and realizes electronic cost.
Above-described embodiment is the preferable embodiment of the present invention, but embodiments of the present invention are not by the embodiment
