Fully collapsible invalid's chair includes two sets locking mechanisms: fully collapsible invalid's chair is locked in opening working condition or folding work state
The sliding locking mechanism of slide lock between sliding part 8, foot-driven lever 7, and unlock vehicle frame are locked machine by frame locking mechanism 14
The vehicle frame unlock operating parts of structure 14, the sliding for unlocking sliding locking mechanism unlock operating parts.In the present embodiment: vehicle frame unlock behaviour
Workpiece 11, sliding unlock operating parts are same unlock operating parts-carrying handle 13, that is to say, that: rotation carrying handle 13 unlocks vehicle frame lock
Determine to unlock sliding locking mechanism while mechanism, fully collapsible invalid's chair can be converted from working condition is opened to folding work state.
Back bracket 1 specifically includes pulling handle rod 10, backrest cross bar 11, backrest connector 12.Pulling handle rod 10 is U-shaped, and backrest connects
First 12 are connected to the both ends of pulling handle rod 10, and backrest cross bar 11 is connected between backrest connector 12, and frame locking mechanism 14 is set
It sets on backrest cross bar 11 and is rotatablely connected by turning point c and rear wheel support 3, carrying handle 13.
As is seen in figs 7-10: after frame locking mechanism 14 includes the joint lock 140 being arranged on backrest cross bar 11, is formed in
Tooth cavity 141 on wheel support 3, joint lock 140 can be located at simultaneously, the locking teeth 142 in tooth cavity 141, both ends be against tooth cavity respectively
Elastomeric element 143 between 141 and locking teeth 142, carrying handle 13 pass through joint lock 140 and cooperate with locking teeth 142.Wherein: carrying handle
Setting first cooperates inclined-plane 144 on 13, the second cooperation of setting inclined-plane 1420 on locking teeth 142, the first cooperation inclined-plane of carrying handle 13
144 cooperate inclined-plane 1420 to be slidably matched with the second of locking teeth 142.Elastomeric element 143 uses pressure spring.
For wheelchair when opening working condition or folding work state, due to the effect of elastomeric element 143, locking teeth 142 is same
When be located at joint lock 140, in tooth cavity 141, locked between rear wheel support 3 and back bracket 1.When unlocking frame locking mechanism 14,
Carrying handle 13 is rotated, the first cooperation inclined-plane 144 of carrying handle 13 and the second cooperation inclined-plane 1420 of locking teeth 142 slide relatively, by position
Joint lock 140 is released in the locking teeth 142 in joint lock 140, elastomeric element 143 is pressurized, and rear wheel support 3 and back bracket 1 can
To relatively rotate；When joint lock 140 turns to certain angle, locking teeth 142 is pushed into joint lock 140 by elastomeric element 143,
Frame locking mechanism 14 locks.The specific structure applicant of frame locking mechanism 14 individually carried out patent application, therefore
Herein with regard to no longer being repeated.
As illustrated in figs. 11-14: sliding locking mechanism includes locked component, the solution that is arranged between locked component and carrying handle 13
Lock transmission component.Wherein:
Locked component include the locked groove 150 being provided on footrest pipe 7, the locking piece shaft 151 being fixedly connected in sliding part 8,
The locking piece 152 being rotatably connected in locking piece shaft 151.It is located on front side of locking piece shaft 151 on locking piece 152 and is provided with lock
Tongue 1520 is provided with the second trundle auxiliary section 1521,1521 court of the second trundle auxiliary section on rear side of locking piece shaft 151
It is provided with to 151 side of locking piece shaft (front side) and extends cooperation inclined-plane 1522 along back upper place.Locked component further includes that setting exists
Lock tongue 1520 is driven to be inserted into the elastomeric element 153 in locked groove 150 between sliding part 8 and lock tongue 1520.
Unlock transmission component includes the first transmission component matched with carrying handle 13, second matched with locked component biography
Dynamic component, is connected between the first transmission component, the second transmission component by hauling rope 154.
