Abstract

A bicycle labor-saving device comprises two long glue tapes or two long springs, hanger supports and tackles. The hanger supports are arranged on the bicycle coat hanger or compression springs below the saddle; top ends of the two long glue tapes or the two long springs are respectively tied inside the rings at both sides of the hanger supports and inside the rings at the upper part of the tackles; open rings at the lower part of the tackles are respectively linked to the internal journal of the left and the right pedals. The utility model can launch manpower, which is accumulated in easily available areas, into areas that manpower cannot reach, so as to push forward the rear wheel and save labor force. Since the overall structure is characterized in small friction area and low energy loss, considerable effects on saving labor force can be fulfilled.

Description

Bicycle power-saving devices

Technical field

The utility model relates to a kind of bicycle power-saving devices.

Background technology

A kind of work-saving device is arranged at present, and it mainly is made up of lever and chain.The lever middle part is installed in right handle one side of handle-bar, and chain is hingedly mounted on the lever lower end.During driving, with the upper end that the right hand is moved lever, the chain of its lower end just drives the front-wheel rotation that sprocket wheel and ratchet are housed.Because this device can only drag front-wheel in the compartment of terrain, thereby its labor-saving effect is relatively poor, and only also be absolutely unsafe with left hand grasp handlebar.

Summary of the invention

Poor for overcoming above-mentioned labor-saving effect, unsafe problem of driving a vehicle, the utility model provides a kind of simple and easy laborsaving and safe device.Shown in Fig. 1-2, the utility model mainly comprises hanger, long adhesive tape or long spring and suspension hook.Wherein, A is long-pending merit zone, and B is for putting the merit zone.

Hanger is made up of hook and two legs that weld or be connected the hook middle part.There is annulus the hook both sides, after the leg centre twists into the shape of clip, are welded in the hook middle part.When hanger was assembled on the clothes hanger, the flexible bayonet socket in leg top was connected with hook by screw, and the also flexible bayonet socket in bottom is connected by screw, nut and clothes hanger.Different with vehicle and purposes, the sectional dimension and the length dimension of long adhesive tape or long spring slightly change.Suspension hook one side is an annulus, and opposite side is the opening annulus.

This device is made up of two long adhesive tape or two long springs, hanger and suspension hooks.Hanger be installed on the carrying rack of bicycle or the seat stool below compression spring on, two long adhesive tape or two long spring upper ends tie up to respectively in the annulus of hanger both sides, the lower end ties up to respectively in the annulus of suspension hook, and the opening annulus of suspension hook lower end is hooked in respectively on the inboard axle journal of left and right sides pedal.

Laborsaving principle of the present utility model is: the merit of the regional inner product that human body is easily exerted oneself is emitted in the zone that can not exert oneself, and the powerful trailing wheel that promotes advances, and reaches laborsaving purpose.

The beneficial effects of the utility model are: simple in structure, easy to manufacture, the labor-saving effect is remarkable.

The specific embodiment

The specific embodiment of the present utility model is illustrated in conjunction with the accompanying drawings.

Sign flag in the above-mentioned accompanying drawing is: the 1-hanger; The 1A-hook; The 1B-leg; The 1C-annulus; The 1D-leg; The 1D1-screw; The 1D2-screw; The 1D3-nut; 1D4-elasticity draw-in groove; 1D5-elasticity draw-in groove; The long adhesive tape of 2-; The long spring of 3-; The 4-suspension hook; The 4A-annulus; 4B-opening annulus; 5-seat stool; The 6-compression spring; The 7-stretcher; The 8-clothes hanger; The 9-iron wire.

Shown in Fig. 3-6, hanger (1) is made up of at two legs (1B or 1D) at hook (1A) middle part with welding (or connection) hook (1A), hook (1A) is made by iron wire, there is annulus (1C) at the iron wire two ends, leg (1B) is also made by iron wire, is welded in hook (1A) middle part respectively twist into the shape of clip in the centre after.When hanger is installed on the clothes hanger (8), leg (1D) can be made by metal or non-metal, and the flexible draw-in groove in top (1D4) is connected with hook (1A) by screw (1D1), the also flexible draw-in groove in bottom (1D5) is connected with clothes hanger (8) with nut (1D3) by screw (1D2).

Long adhesive tape (2) is made by the good rubber of elasticity, tightens with iron wire (9) after the bending two ends.Different with vehicle and purposes, the sectional dimension and the length dimension of long adhesive tape (2) or long spring (3) slightly change, and its cross sectional shape can be circle, ellipse or rectangle.

Suspension hook (4) is that the iron wire of circular, ellipse or rectangle is made by cross sectional shape.Suspension hook (4) top is annulus (4A), and the bottom is opening annulus (4B).

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 5, hanger (1) is installed on following two compression springs (6) of present stool (5) or on the clothes hanger (8), long adhesive tape (2) or long spring (3) upper end tie up to respectively on the annulus (1C) of hanger (1) both sides, the lower end ties up on suspension hook (4) the top annulus (4A), and the opening annulus (4B) of suspension hook (4) bottom is hooked in respectively on the inboard axle journal of left and right sides stretcher (7).

During push down on the pedal (7), long adhesive tape (2) or long spring (3) are elongated and long-pending merit.After pedal (7) turned over the dead point, long adhesive tape (2) or long spring (3) all discharged the merit of being amassed because of resilience, promoted trailing wheel forcefully and continued rotation.Whenever step on a pedal (7) and just finish a long-pending merits and demerits journey of putting, axis rotates a circle and then finishes two long-pending merits and demerits journeys of putting.Because of the total friction face is very little, degradation of energy is also very little, so can produce significant labor-saving effect.

The beneficial effects of the utility model are: simple in structure, easy to manufacture, the labor-saving effect is remarkable.
