To effective reconditioning, more popular at present is four wheel frame walk helpers, feature be it is mobile flexible, easily operated, still
Less stable uses walk helper, it is necessary first to which walk helper is pushed away forward into one, it is necessary to user possesses preferable operational capacity
Step, while body must be kept straight and upright, then in a pedal walking-aid, walk helper is kept when user walks
It is motionless, an other pin is stepped, finally, an other pin is strided forward in walk helper, walk helper remains in that motionless.It is constantly mobile
Walk helper forward, repeats above procedure.Common four-wheel walk helper, which typically all possesses, has hand held to brake or push brake work(
Can, but in use, on the one hand, user's hand strength needs to support whole body, it is difficult to controls hand held to brake
Dynamics, use it is very inconvenient, on the other hand, user's frequent fault be by walk helper put too before, when user will
When slipping, the pressure for being applied to handrail is gradually reduced, press-down type braked must act on it is also extremely limited.
The content of the invention
The invention aims to solve shortcoming present in prior art, and a kind of falling-resistant walk helper proposed.
To achieve these goals, present invention employs following technical scheme：
A kind of falling-resistant walk helper, including walk helper and shoe, the walk helper rear axle is fixed with rear wheel bar, described
The rear wheel bar other end is fixed by handrail and front wheel bar, and the rear wheel bar is consolidated with front wheel bar center section by head rod
Fixed, the front wheel bar bottom is fixed with front-wheel wheel shaft, is fixed between the front wheel bar by second connecting rod on top, and front-wheel
The slip cap that can adjust fixation is installed among bar, fixed between described two slip caps by the 3rd connecting rod, the front-wheel
With being mounted on shoe on rear axle, the shoe is fixed by gear and wheel shaft, and the gear surface passes through
Hinge is provided with swing rod, and the swing rod afterbody is fixed by the first spring with gear, tooth top and the nothing at the top of rack of the gear
Limit close, the rack is fixed by sliding pin and cam, is connected at the top of the cam by second spring with fixed block.
Preferably, the rear wheel bar and front wheel bar are all scalable.
Preferably, the swing rod is eccentric structure, and swing rod barycenter is located remotely from the side of the first spring.
Preferably, curvature becomes larger the sliding pin from top to bottom, when cam is located at sliding pin top, rack and pinion
Engagement, when cam is located at sliding pin bottom, rack and pinion is not interfere with each other.
Preferably, first spring is compression spring, and the second spring is extension spring.
The beneficial effects of the invention are as follows：
1st, the present invention does not need the brake of user's pro-active intervention, and when walk helper position is earlier, user's crank will
When falling down forward, shoe can effectively, promptly locked front and back wheel, fixed walk helper, protect user；
2nd, the present invention is locked in front and back wheel, and user only needs to pull back walk helper once, you can allows shoe to reset, helps
Row device normal use, is not required to complex operations, effectively helps user to carry out rehabilitation training；
3rd, the present invention can regard speed-limiting protective device when user runs into descending section；
4th, front wheel bar of the present invention, rear wheel bar can telescopic adjustment, suitable for the user of different building shape.
Brief description of the drawings
Fig. 1 is a kind of structural representation of falling-resistant walk helper proposed by the present invention；
Fig. 2 is the structural representation under a kind of shoe normal condition of falling-resistant walk helper proposed by the present invention；
Fig. 3 is the structural representation under a kind of shoe locking state of falling-resistant walk helper proposed by the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.
Reference picture 1-3, a kind of falling-resistant walk helper, including walk helper 1 and shoe 2, the wheel shaft of walk helper trailing wheel 3 is with after
Wheel bar 4 is fixed, and the other end of rear wheel bar 4 is fixed by handrail 5 and front wheel bar 6, and rear wheel bar 4 and the center section of front wheel bar 6 pass through the
One connecting rod 7 is fixed, and rear wheel bar 4 and front wheel bar 6 are all scalable, facilitates the user of different building shape, the bottom of front wheel bar 6 is with before
Take turns 8 wheel shafts to fix, fixed between front wheel bar 6 by second connecting rod 9 on top, and be provided among front wheel bar 6 adjustable solid
Fixed slip cap 10, fixed by the 3rd connecting rod 11 between two slip caps 10, front-wheel 8 on the wheel shaft of trailing wheel 3 with being mounted on
