Abstract
A labor-saving bicycle solves the problem that the traditional bicycle can go forward by pedaling one lap to drive the sprocket wheel at the centre shaft, and need to take great effort. A ratchet-and-pawl mechanism is arranged at the two ends of the centre shaft, the pawl mechanism is fixed on the centre shaft, and the pedal lever is sleeved on the ratchet. A bracket with an idler wheel is arranged at the middle part of the frame. Bearings are arranged at the ends of the two pedal levers. A wire cable is sheathed on the idler wheel. The two ends of the wire cable are connected with the joint of the bearing sheath arranged on the two pedal levers respectively. A pedal lever retainer is arranged under the the frame. The utility model has the advantage of being timesaving and laborsaving as the length of the pedal lever gets prolonged, a bigger chain-wheel is used, and the chain-wheel can be driven by pedaling up and down.
Description
Technical field
The utility model is a kind of labour-saving bicycle.
Background technology
Traditional bicycle, the size of pedal rod is short, and people scrunch 360 ° of sprocket wheels that promptly drive the axis place week of pedal, and bicycle is walked forward.Relatively require great effort.Running into upward slope have to push away sometimes and walking.
Summary of the invention
The purpose of this utility model is, solves above-mentioned existing existing problem, and a kind of labour-saving bicycle is provided.
The utility model is achieved in that at the axis both ends installs ratchet and pawl arrangement, and detent mechanism is fixed on the axis, and two pedal rods are fixed on the ratchet by the pin suit, the pedal rod lengthening.Roller is installed rolling wheel support by bearing pin, and rolling wheel support is installed at the vehicle frame middle part; Bearing is installed in end at two pedal axostylus axostyles, and steel wire loop is on roller, and the end of steel rope is connected with the bearings mounted overcoat point of connection in end of two pedal axostylus axostyles respectively; The pedal rod position-limited rack is installed in the vehicle frame bottom.
Advantage of the present utility model is, owing to increase the length of pedal rod, adopts big trochal disc, upper and lowerly scrunches the pedal swing and can drive wheel disc and rotate, and saves time, laborsaving.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of improved drive part;
Fig. 3 is the structural representation of ratchet and pawl arrangement;
The specific embodiment
Describe in detail below in conjunction with accompanying drawing: as shown in the figure, at axis 10 both ends ratchet and pawl arrangement is installed, detent mechanism 9 is fixed on the axis 10, and two pedal rods 5 are fixed on the ratchet 11 by the pin suit, pedal rod 5 lengthenings.Roller 3 is installed rolling wheel support 2 by bearing pin, and rolling wheel support 2 is installed at vehicle frame 1 middle part; In the end of two pedal axostylus axostyles bearing 8 is installed, steel rope 4 is enclosed within on the roller 3, and the end of steel rope 4 is connected with the overcoat point of connection that bearing 8 is installed in the end of two pedal axostylus axostyles respectively; Pedal rod position-limited rack 7 is installed in vehicle frame 1 bottom.
