Portable child rehabilitation walker
Technical field
The present invention relates to a kind of medical auxiliary apparatus field, be specifically related to a kind of portable child rehabilitation walker.
Background technology
Nowadays the case that child is injured is more and more, when recovering, the walking aid of practicality is also of all kinds, but existing is all walking aid without pulley, child's strength is originally just little, also be just difficult to mention or gruelling, cause not having very large help to recovering, and existing walking aid be mostly fixed, cannot draw in, make to deposit constant.
Summary of the invention
The object of the invention is to overcome the above problem that prior art exists, a kind of portable child rehabilitation walker is provided, the present invention is convenient for carrying and is conducive to trip, and does not take up space, conveniently deposits.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of portable child rehabilitation walker, comprise that two three corner steadies form, between two described three corner steadies, by folding cross bar, be fixedly connected with, described three corner steadies are connected to form by first connecting rod, second connecting rod and third connecting rod circulation, described first connecting rod is provided with and is connected draw-in groove with the junction of described third connecting rod, and be provided with the first pulley, the junction of described second connecting rod and described third connecting rod is provided with the second pulley.
Further, the quantity of described folding cross bar is 2.
The invention has the beneficial effects as follows:
1, be convenient for carrying and be conducive to trip.
2, do not take up room, conveniently deposit.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of description, below with preferred embodiment of the present invention and coordinate accompanying drawing to be described in detail as follows.The specific embodiment of the present invention is provided in detail by following examples and accompanying drawing thereof.
Accompanying drawing explanation
Accompanying drawing described herein is used to provide a further understanding of the present invention, forms the application's a part, and schematic description and description of the present invention is used for explaining the present invention, does not form inappropriate limitation of the present invention.In the accompanying drawings:
Fig. 1 is the structural representation of the present invention while using.
Fig. 2 is the structural representation of the present invention while depositing.
Number in the figure explanation: 1, folding cross bar, 2, three corner steadies, 3, draw-in groove, the 4, second pulley, 5, handrail, 6, third connecting rod, 7,, 8, second connecting rod, the 9, first pulley.
The specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
Shown in Fig. 1, portable child rehabilitation walker, comprise that two three corner steadies 2 form, between two described three corner steadies 2, by folding cross bar 1, be fixedly connected with, described three corner steadies 2 are connected to form by first connecting rod 7, second connecting rod 8 and third connecting rod 6 circulations, described first connecting rod 7 is provided with and is connected draw-in groove 3 with the junction of described third connecting rod 6, and is provided with the first pulley 9, and described second connecting rod 8 is provided with the second pulley 4 with the junction of described third connecting rod 6.
Further, the quantity of described folding cross bar 1 is 2.
Further, between described first connecting rod and second connecting rod for being flexibly connected, between described second connecting rod and third connecting rod also for being flexibly connected.
The operation principle of the present embodiment is as follows:
During use, child uses by handrail 5, by the propelling sheave 4 that travels forward, advances, and described pulley 4 advances only, can not retreat, and prevents back back skating.While depositing, third connecting rod 6 is taken out and drawn in from draw-in groove, folding cross bar 1 bending is drawn in.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
