Part；5, fixing seat；6, sleeve；7, handle is folded.
Fig. 2 is the utility model structure chart.
Fig. 3 is the utility model locking process schematic diagram.
Specific embodiment
Technical solutions of the utility model are described in detail below by attached drawing, but the protection scope of the utility model
It is not limited to the embodiment.
Embodiment 1: a kind of fully collapsible invalid's chair locking device, as depicted in figs. 1 and 2, the locking device includes sleeve 6, preceding
It takes turns connector 4, fixing seat 5, locking piece 3, folding handle 1 and folds handle 7.The sleeve 6 is sleeved on wheelchair front wheel bracket group
On part, the two sides of sleeve 6 are provided with front wheel members 4, one end port of front wheel members 4 be provided be mutually matched it is rectangular recessed
Slot, the front wheel members 4 positioned at 6 two sides of sleeve pass through sleeve 6 and are fixedly connected by groove.The fixing seat 5 is arranged in wheelchair
The upper end of rear wheel support component, the both ends of fixing seat 5 are respectively installed with locking piece 3, are provided between fixing seat 5 and locking piece 3
Spring 2；The outer surface surrounding of the locking piece 3 is provided with locking teeth, and the lower lumen of front wheel members 4 is provided with and locking teeth
The lock slots to match；The front wheel members 4 are arranged between locking piece 3 and folding handle 1, and one end of folding handle 1 is set
It is equipped with the slide teeth to match with sliding groove, one end of folding handle 1 is connected by the lower rotational of tooth socket and front wheel members 4
It connects, the other end of folding handle 1 is fixedly connected by folding handle 7.
As shown in figure 3, the locking process of the utility model: artificially opening fully collapsible invalid's chair, be fixedly connected in backrest module
Front wheel members 4 and the fixing seat 5 that is fixedly connected on rear wheel support component produce relative rotation, when in front wheel members 4
When the lock slots of chamber and locking piece 3 reach a suitable position, positioned at 5 two sides of fixing seat locking piece 3 spring 2 effect
It is locked under power in the lock slots of front wheel members 4, so that front wheel members 4 and fixing seat 5 reach relatively-stationary state,
I.e. entire wheelchair reaches lock state.
The unlocking process of the utility model: artificially having carried and folded handle 7, drives the component being fixedly connected with folding handle 1
It rotates counterclockwise, the slide teeth of folding handle 1 is slided on the inclined-plane of the sliding groove of corresponding locking piece 3 respectively, to push lock
Determine part 3 and exit the lock slots of front wheel members 4, so that the front wheel members 4 being fixedly connected on front-wheel support component and fixation
Fixing seat 5 on rear wheel support component loses locking and produces relative rotation, thus realize the unlock of locking device, i.e., entire wheel
The folding of chair unlocks.
As described above, although the utility model has been indicated and described referring to specific preferred embodiment, it must not
It is construed to the limitation to the utility model itself.In the spirit and scope for not departing from the utility model that appended claims define
Under the premise of, it can various changes can be made in the form and details to it.
