Abstract
The utility model relates to a hand wheel for a wheelchair, which comprises road wheels arranged at both sides of the wheelchair. Hand wheels are arranged outside the road wheels, wherein skidproof convex-concave grains are arranged outside the hand wheels. The convex-concave grains and the hand wheels are formed in one step into a whole structure. Connecting rods connected with the inner rings of the road wheels are arranged inside the hand wheels; the connecting rods are fixed on the inner rings of the road wheels through bolts. The utility model has the advantages of simple structure and convenient use, and efficiently performs the function of skid prevention.
Description
Technical field
This utility model relates to wheelchair technical field for disabled persons, the handwheel of the concrete driving wheelchair walking that relates to a kind of used on wheelchair.
Background technology
Wheelchair is the auxiliary facilities that disabled often use, and general wheelchair all has two road wheels, and these two road wheels are arranged on the both sides of wheelchair, is used to support wheelchair and drives the wheelchair walking.
In the existing wheelchair, generally adopt its walking of driven in two modes.A kind of is to adopt the hand handwheel that horizontally rotates, and drives wheel turns by bevel gear, thereby drives the wheelchair walking; The handwheel of this wheelchair occupies very large space, so the volume of wheelchair is very big, is not suitable for folding, and perhaps folding back occupation space is also very big.Another is, in the both sides of wheel two handwheels is set again, directly rotates handwheel with hands, and handwheel can drive wheel turns, thereby drives wheelchair walking (as shown in Figure 1).But the hands contact surface smoother of this kind handwheel 01 when making user satiny on hand, is held handwheel and is slided easily, makes to drive comparatively difficulty of motions such as wheelchair advances, falls back.
The utility model content
Technical problem to be solved in the utility model is, overcomes problems of the prior art, and a kind of wheelchair handwheel is provided, and this handwheel outer surface is provided with anti-skidding tongue and groove, can prevent effectively that like this staff from skidding on handwheel.
In order to address the above problem the technical solution of the utility model is such:
A kind of wheelchair handwheel comprises the road wheel that is arranged on the wheelchair both sides, and the arranged outside of road wheel has handwheel, and wherein, the arranged outside of handwheel has anti-skidding convex-concave lines.
Described convex-concave lines and handwheel are one-time formed integrative-structure.
Described handwheel inboard is provided with the connecting rod that is connected with the road wheel inner ring, and described connecting rod is by on the inner ring that is bolted to road wheel.
Beneficial effect, handwheel described in the utility model is simple in structure easy to use, in use, can effectively play skidproof effect and feel is better.
Description of drawings
Describe this utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is the handwheel sketch map of wheelchair in the prior art;
Fig. 2 is a handwheel structural representation described in the utility model.
The specific embodiment
For technological means, creation characteristic that this utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth this utility model.
Referring to Fig. 2, a kind of wheelchair handwheel, this handwheel are arranged on the wheelchair that can fold, be provided with the wheel 1 that is used to walk in the both sides of wheelchair, the arranged outside of wheel 1 has handwheel 2, and user firmly rotates handwheel 2, handwheel 2 promptly can rotate by driven wheel 1, thereby drives the motion of wheelchair.
In order to prevent that handwheel 2 from contacting with ground, the diameter of handwheel 2 is less than the diameter of wheel 1, and handwheel 2 is coaxial fixing with wheel 1.The inboard of handwheel 2 is provided with the connecting rod 21 that is connected with wheel 1, and connecting rod 21 is four or six, be evenly distributed in the circumference of handwheel 2, and connecting rod 21 is connected with the wheel hub of wheel 1 inner ring by bolt 22.
Skid when preventing that user from holding handwheel 2, be provided with anti-skidding convex-concave lines 23 on the surface of handwheel 2, each lines width of convex-concave lines 23 conforms to adult's finger beam, and the adult holds handwheel 2 with frontier defense.And convex-concave lines 23 is one-time formed integrative-structure with handwheel 2, promptly is about to 23 one-shot formings of convex-concave lines when handwheel is made.
Compared with prior art, handwheel described in the utility model is simple in structure easy to use, in use, can effectively play skidproof effect.
More than show and described ultimate principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; this utility model is not restricted to the described embodiments; that describes in the foregoing description and the description just illustrates principle of the present utility model; this utility model also has various changes and modifications under the prerequisite that does not break away from this utility model spirit and scope, and these changes and improvements all fall in claimed this utility model scope.The claimed scope of this utility model is defined by appending claims and equivalent thereof.
