Abstract

The utility model discloses a kind of single pin bicycle, include bicycle main body, vehicle frame lower beam in bicycle main body, the crank of pedal connection, and trailing wheel central shaft, steel disc is resetted, and is connected to the anti-down mechanism at trailing wheel central shaft two ends in the crank front lower place, the L-shaped being connected on vehicle frame lower beam characterized in that, also including；The L-shaped resets the branch levels of steel disc one and is hinged on the downside of vehicle frame lower beam, and another branch is upward；The anti-down mechanism includes the fix bar being fixed on trailing wheel central shaft, is fixedly connected on the damping spring of fix bar lower end, is fixedly connected on the bracing diagonal of damping spring lower end, and the auxiliary wheel installed in bracing diagonal lower end；The bracing diagonal, from top to down laterally away from bicycle.This bicycle can single pin ride, be not easy to topple over.

Description

A kind of single pin bicycle

Technical field

The utility model belongs to bicycle art, and in particular to the bicycle that a kind of single pin is ridden.

Background technology

Can only the cycling of pin disabled person or the wounded, a pin stepped on after pedal, and pedal is not easy before returning to Upper position, so can not continuous Pedalling, it is impossible to continue to ride.Ridden again due to a pin, stability is bad, getting on the bus, It is easier to fall down when getting off.For these problems, to being improved on the basis of existing bicycle.

The content of the invention

Technical problem to be solved in the utility model is：In view of the shortcomings of the prior art there is provided a kind of single pin certainly Driving.

To realize the purpose of the utility model, it is achieved using following technical scheme：A kind of single pin bicycle, includes Vehicle frame lower beam in bicycle main body, bicycle main body, the crank of pedal connection, and trailing wheel central shaft, it is characterised in that also Include and reset steel disc in the crank front lower place, the L-shaped being connected on vehicle frame lower beam, and be connected to trailing wheel central shaft The anti-down mechanism at two ends；The L-shaped resets the branch levels of steel disc one and is hinged on the downside of vehicle frame lower beam, and another branch is upward；It is described Anti-down mechanism includes the fix bar being fixed on trailing wheel central shaft, is fixedly connected on the damping spring of fix bar lower end, fixed It is connected to the bracing diagonal of damping spring lower end, and the auxiliary wheel installed in bracing diagonal lower end；The bracing diagonal, from upper Down laterally away from bicycle.

Compared with prior art, the beneficial effects of the utility model are：1st, L-shaped is set to reset steel in crank front lower place Piece, when crank is rotated down forward, gently lifts pin, L-shaped, which resets steel disc, makes crank rotate, even if crank resets, energy Continue pedal forward；2nd, L-shaped resets the branch of steel disc one and vehicle frame lower beam downside and is hinged, can only the people that rides of right crus of diaphragm, just L-shaped Steel disc is resetted to go on the right side of bicycle, can only the people that rides of left foot, L-shaped is just resetted steel disc and gone on the left of bicycle, so may be used With adapt to can only the people that rides of left foot or right crus of diaphragm ride；The 3rd, anti-down mechanism be set, it is therefore prevented that bicycle is toppled over；The 4th, damping is set Spring, radially buffers to left-leaning or Right deviation, increases the comfort level ridden.

Brief description of the drawings

Fig. 1 is the schematic diagram of the utility model stereochemical structure.

Fig. 2 is the schematic diagram of the anti-down mechanism of the utility model.

1st, bicycle main body；11st, vehicle frame lower beam；12nd, L-shaped resets steel disc；13rd, anti-down mechanism；131st, fix bar；132、 Damping spring；133rd, bracing diagonal；134th, auxiliary wheel.

Embodiment

Embodiment of the present utility model is made a detailed explanation below according to accompanying drawing.

According to Fig. 1-2, a kind of single pin bicycle of the present embodiment includes in bicycle main body 1, bicycle main body 1 Vehicle frame lower beam 11, the crank of pedal connection, and trailing wheel central shaft, it is characterised in that also include front lower in the crank Side, the L-shaped being connected on vehicle frame lower beam 11 reset steel disc 12, and are connected to the anti-down mechanism at trailing wheel central shaft two ends 13；The L-shaped resets the branch levels of steel disc 12 1 and is hinged on the downside of vehicle frame lower beam 11, and another branch is upward；The anti-down mechanism 13 include the fix bar 131 being fixed on trailing wheel central shaft, are fixedly connected on the damping spring 132 of the lower end of fix bar 131, Gu Surely the bracing diagonal 133 of the lower end of damping spring 132, and the auxiliary wheel 134 installed in the lower end of bracing diagonal 133 are connected to；Institute Bracing diagonal 133 is stated, from top to down laterally away from bicycle.

Set L-shaped to reset steel disc in crank front lower place, when crank is rotated down forward, gently lift pin, L-shaped resets steel Piece makes crank rotate, even if crank resets, can continue pedal forward；L-shaped is resetted under the branch of steel disc one and vehicle frame lower beam Side is hinged, can only the people that rides of right crus of diaphragm, L-shaped is just resetted steel disc and gone on the right side of bicycle, can only the people that rides of left foot, just L Shape resets steel disc and gone on the left of bicycle, be so adapted to can only the people that rides of left foot or right crus of diaphragm ride；Anti-down mechanism is set, Prevent toppling over for bicycle；Damping spring is set, left-leaning or Right deviation is radially buffered, increases the comfort level ridden.

Claims

1. a kind of single pin bicycle, include the vehicle frame lower beam in bicycle main body, bicycle main body, the crank of pedal connection, And trailing wheel central shaft, it is characterised in that also include in the crank front lower place, the L-shaped being connected on vehicle frame lower beam reset Steel disc, and it is connected to the anti-down mechanism at trailing wheel central shaft two ends；The L-shaped resets the branch levels of steel disc one and is hinged on car On the downside of frame lower beam, another branch is upward；The anti-down mechanism includes the fix bar being fixed on trailing wheel central shaft, is fixedly connected Damping spring in fix bar lower end, is fixedly connected on the bracing diagonal of damping spring lower end, and under bracing diagonal The auxiliary wheel at end；The bracing diagonal, from top to down laterally away from bicycle.
