Abstract
The utility model relates to a position restorating device, composed of a tension spring and a connecting rod. The utility model is characterized in that one end of the tension spring (2) is fixed on the rear axis (1) of a vehicle. The other end is connected with the connecting rod (3). One end of a rotary rod (4) is movably connected with the connecting rod (3). The other end is fixed on a middle axis (5). The utility model has the advantages of simple structure, easy making, low cost, etc. The utility model is convenient for riding bicycles and tricycles for persons with handicapped lower limb and single limb. The utility model is suitable for riding bicycles and tricycles for persons with handicapped lower limb and single limb.
Description
The utility model belongs to a kind of reset attachment.
At present, two pedals about its structure of bicycle and three-wheel vehicle comprises need people to step on two pedals with both feet when advancing, concerning the people of lower limb, single limb deformity, just make troubles during by bike with three-wheel vehicle.
Goal of the invention of the present utility model is a kind of reset attachment of design, is convenient to lower limb, the handicapped people of single limb by bike and three-wheel vehicle.
The purpose of this utility model is achieved in that it is made up of extension spring and connecting rod, it is characterized in that an end of extension spring is fixed on the rear axle of car, and the other end is connected with connecting rod, and connecting rod and dwang are to flexibly connect, and dwang is fixed on the axis.
When aforesaid dwang was fixed in axis, extension spring was positioned at minimum force, and the pedal of opposite side is positioned at vertex.
When people use, step on pedal downwards with pin, drive dwang by axis and rotate, dwang is strained extension spring by connecting rod like this, when pedal is positioned at nadir, and the power maximum of extension spring, at this moment extension spring just can rotate dwang by connecting rod, and dwang makes pedal get back to vertex by axis again.Go round and begin again, but normally move with regard to bicycle or three-wheel vehicle.
Advantage of the present utility model is as follows:
1. simple in structure, easily manufacture;
2. cost is low;
3. be convenient to lower limb, the handicapped people of single limb by bike and three-wheel vehicle.
Embodiment accompanying drawings of the present utility model is as follows.
Fig. 1 is the structural representation of extension spring power minimum of the present utility model.
Fig. 2 is the structural representation of extension spring drawing-off of the present utility model.
Fig. 3 is the structural representation of extension spring power maximum of the present utility model.
Fig. 4 is the structural representation that extension spring of the present utility model resets.
As shown in the figure: the 1st, rear axle, 2 is that an end is fixed in rear axle 1, the other end is in connecting rod 3 bonded assembly extension springs, 4 is that an end is captiveed joint with axis 5, the dwang that the other end and connecting rod 3 flexibly connect, the 6th, the pedal of opposite side, when pedal 6 is positioned at vertex, extension spring 2 power minimums.
When people use, step on pedal 6 downwards with pin, driving dwang 4 by axis 5 rotates, dwang 4 is strained extension spring 2 by connecting rod like this, when pedal 6 is positioned at nadir, the power maximum of extension spring 2, extension spring at this moment 2 just can rotate dwang 4 by connecting rod 3, and dwang 4 makes pedal 6 get back to vertex by axis 5 again.Go round and begin again, bicycle or three-wheel vehicle are normally moved.
Claims (2)
