Abstract

The utility model relates to a plastic hand wheel connecting piece of a wheel chair, comprising traveling wheels and hand wheels, wherein the traveling wheels and hand wheels are injection molding pieces; the inner side of each hand wheel is injection-molded with the hand wheel into an integrated connecting buckle; the extending end of the connecting buckle is in a multi-valve shape with a blind hole and an opening; the inner ring of each traveling wheel is also provided with a connecting column matched with the extending end of the connecting buckle and provided with a through hole; and the connecting column is internally provided with an expansion plug matched with the extending end of the connecting buckle. The hand wheel does not need tools and is directly inserted in the connecting column on the traveling wheel by the connecting buckle thereon, thus saving time and labor, and also omitting fastening pieces; and the traveling wheels and hand wheels are plastic pieces, thus not only reducing the weight, but also reducing the production cost as well as labor intensity of the disabled or a patient. In addition, the plastic hand wheel connecting piece has fresher and more attractive appearance, leads the connection of the two wheels to be firmer and have safer use due to addition of the expansion plugs.

Description

Wheelchair plastics handwheel connector

Technical field

This utility model relates to the strength member on a kind of wheelchair handwheel, and particularly a kind of people with disability or patient use the wheelchair plastics handwheel connector on the wheelchair.

Background technology

The wheelchair that now general people with disability or patient use all has two road wheels, this two road wheel is arranged on the both sides of wheelchair, be used to support wheelchair and drive the wheelchair walking, control for making things convenient for user, both sides at road wheel also are provided with two handwheels again, handwheel is coaxial fixing with road wheel, available hands directly rotates handwheel control wheelchair, drive the road wheel rotation that connects into integral body with handwheel by handwheel, thereby drive advancing or retreating of wheelchair walking and control wheelchair, the inboard of handwheel is provided with and the uniform connecting rod that is connected of road wheel, and connecting rod is to be connected by the wheel hub of securing member with the road wheel inner ring, and trouble is installed.

The patent No. 200820157026.7 " a kind of wheelchair handwheel " only provides a kind of outer surface at handwheel to be provided with anti-skidding convex-concave lines, and with the handwheel one-shot forming, its described handwheel inboard is provided with the connecting rod that is connected with the road wheel inner ring, but described connecting rod is still by on the inner ring that is bolted to road wheel, and still trouble is installed.

Summary of the invention

Technical problem to be solved in the utility model is: a kind of wheelchair plastics handwheel connector is provided, simple in structure, do not need instrument directly handwheel to be fixed on the road wheel by connector, install save time, laborsaving, it is firm to connect, appearance is neat and artistic.

The technical scheme in the invention for solving the above technical problem is: wheelchair plastics handwheel connector, comprise road wheel, handwheel, described road wheel, handwheel all are moulding, the inboard of described handwheel has and handwheel injection moulding all-in-one-piece junction button, the external part of described junction button is the shape of distinguishing of band blind hole and opening more, have on the inner ring of described road wheel with junction button to cooperate the joint pin of being with through hole, the plug that rises that cooperates with junction button also is installed in the joint pin.

Compared with prior art, advantage of the present utility model is: this wheelchair plastics handwheel connector is directly inboard uniform being injection molded into of handwheel, not needing instrument just can directly stretch in the joint pin on the road wheel installs, save time, laborsaving, two road wheels, handwheel all are moulding, also save securing member, alleviated weight, reduced production cost.The rustless class of fastener-free simultaneously, appearance is more neat and artistic, has also adorned the plug that rises in the through hole of joint pin, makes wheel, road wheel connection more firm, uses safer.

The specific embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is further described.

8 uniform junction button 2-1 are arranged on handwheel 2 inner peripheral, be injection molded into handwheel 2 one-shot formings, the external part of junction button is distinguished shape 2-2 for two of band blind hole and opening.

Road wheel 1 also is a moulding, the joint pin 1-1 that 8 band through holes of uniform corresponding junction button 2-1 are arranged on its inner ring wheel hub, the junction button 2-1 that elder generation passes through handwheel 2 on it, insert each the joint pin 1-1 internal fixation on the road wheel respectively, also with the retroserrate plug 3 that rises of front end, tightly embed junction button 2-1 by through hole on the joint pin and upward be with two of blind hole to distinguish in the shape 2-2 then, distinguish the outside spreading of shape 2-2 two, the through hole of being close on the road wheel is fixed, and handwheel 2 and road wheel 1 is fastened whole.

Only with hand rotates handwheel 2, just drive with handwheel 2 fixedly all-in-one-piece road wheel 1 rotate and drive wheelchair and walk, because of handwheel, the road wheel of wheelchair is that plastics two-wheeled deal is light, use laborsavingly, alleviated people with disability or patient's labor intensity.The two-wheeled junction is except that the tensioner that junction button is arranged connects, and the tensioner fixation of the plug that rises in addition makes the two-wheeled connection more firm, uses safer.
