Description
Technical field
This utility model relates to medical apparatus and instruments and rehabilitation material field, and what be specifically related to is a kind of bank crossed front-wheel of wheelchair.
Background technology
Wheelchair is lower limb disability people's auxiliary walking instrument, wheelchair is simple in structure, convenient and practical aid, but the wheelchair of the especially preceding steamboat of wheelchair runs into bank in advancing usually, it is relatively poor that it crosses the bank ability, need there be the auxiliary wheelchair of people could cross bank, in the actual life, although the facility of a lot of Convenient wheelchair walkings has been arranged, but and imperfection, and the part place is subjected to technical limitations, still has bank as subway platform, road tooth etc., makes user use wheelchair inconvenience.
The utility model content
The purpose of this utility model is to overcome the above problem that prior art exists, and a kind of bank crossed front-wheel of wheelchair is provided, and more convenient effective raising wheelchair is crossed the bank ability.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, this utility model is achieved through the following technical solutions:
A kind of bank crossed front-wheel of wheelchair, comprise the wheelchair cradling piece that connects wheelchair, the lower end of described wheelchair cradling piece is the connecting rod axle sleeve, pitman shaft is rotatable by described connecting rod axle sleeve, described pitman shaft two ends fixedly have universal axle sleeve respectively, described universal drive shaft puts and connects the jockey pulley support, and described jockey pulley support connects jockey pulley by the jockey pulley axle.The universal drive shaft of main wheel support is matched with described universal axle sleeve, be connected with collar on the universal drive shaft on the described universal drive shaft, described main wheel support connects main wheel by main axle, and described universal axle sleeve opposite side fixedly has regulating handle, and fixing handle clip is arranged on the described handle.Manufacture the rotating bar linkage structure of being formed by bolt and link in the middle of the described pitman shaft.
Usually during operation, described main wheel in ground, and with known to take turns the Wheel-chair operation consistent, when meeting bank when advancing, keeping straight on arrives described bank edge, keeps the wheel described main wheel forward of Wheel-chair also a small amount of thrust to be arranged, and opens the handle locating button, and driving handle arrives latched position forward.Described handle drives described universal axle sleeve and rotates forward, described jockey pulley moves downward, described main wheel moves upward, described jockey pulley on the described bank, and described main wheel reaches can cross described bank position, and car can continue to move ahead, described main wheel arrives on the described bank, at this moment, reply described handle, the wheel Wheel-chair can normally be advanced.
To folding wheel chair, as long as manufacture rotating bar linkage structure in the middle of connecting rod, the wheelchair cradling piece is rotatable to get final product.
The beneficial effects of the utility model are:
The bank the crossed front-wheel of wheelchair of the present utility model does not influence essential structure and the use of common wheelchair, makes things convenient for to greatest extent to realize the bank action in the slant range of wheelchair manufacturing standard, has made things convenient for the use of wheelchair, has improved the function that wheelchair uses.This utility model is simple in structure, and technology is simple, and is few with material, few to the weight increase of wheelchair, makes simply, is easy to produce.
