Description

Adjustable Force-saving walking stick

Technical field:

The utility model relates to a kind of medical health apparatus, more particularly be about lower limb disability or oldaged physically weak person etc. be used for power-assisted, rely on, with the adjustable Force-saving walking stick in step.

Background technology:

Common known crutch majority is walking stick, tuck in folder formula crutch, it all is the power-assisted instrument that uses for residual patient, but use height that all can not the regulated at will crutch when being to use, can not be according to using needs to elongate or shorten its length or height, bring inconvenience to the user, simultaneously also be not easy to carry and deposit, therefore do not satisfy people's user demand.

Summary of the invention:

The purpose of this utility model is to provide a kind of can eliminate above-mentioned shortcoming, have rational in infrastructure, regulate laborsaving, convenient use, the adjustable Force-saving walking stick of advantages such as scalable length height, especially select the roll adjustment box structure of this convenient power-saving for use, make movable tooth thick stick on the cane bar, rise freely or decline, length and the high low action of regulating crutch have been played, be of value to the posture that the user has regulated easily or squatted down, be the isolated plant that desirable power-assisted, body-building is provided in user especially extremity disabled persons life or the work, has relied on.

Technical scheme is a kind of adjustable Force-saving walking stick, be by the cane holder, cane bar and roll adjustment case constitute, movable tooth thick stick and roll adjustment case are installed on the cane bar, wherein movable tooth thick stick is installed in the ladder-type trough on the cane bar, roll adjustment case one side has a sleeve pipe, casing pipe sleeve is contained on the cane bar, a pair of speed changing transmission gear is housed in case, its driven gear and movable tooth thick stick are connected with a joggle, the axle of driving gear leans out the outer part of case and links to each other with rocking handle; the rocking handle other end is equipped with handle; the back side of movable tooth thick stick is ladder type pin shape, is installed in the dovetail groove of cane bar handle; adopt hinge element to be connected respectively between rocking handle and the driving gear shaft; can change the height of crutch by the rotation of rocking handle, satisfy the Operations Requirements that the user has gone up and squatted down.

Another advantage of this device is: if patient body takes a turn for the better, only need general walking need power-assisted, do not regulate the crutch height in case of necessity, only need the roll adjustment case is pulled down, not only avoided the roll adjustment case wearing and tearing but also can light use and portable.

The adjustable Force-saving walking stick of the utility model is selected the roll adjustment box structure of convenient power-saving for use, make movable tooth thick stick on the cane bar, freely rise or descend, played the length of regulating crutch, high low action, be of value to that the user has regulated easily or the decline posture, be user the provide convenience action and the assurance of taking exercises, it is non-adjustable to have solved all kinds of for a long time crutch height, carry inconvenience, use problems such as effort, have rational in infrastructure, regulate laborsaving, easy to use, retractable length, just, characteristics such as safe in utilization are desirable power-assisteds during people live or work, body-building, the isolated plant of relying on.
