Description

Prop stand for bicycle treadle turnover device

Technical field:

The utility model relates to technical field of bicycles, but the folding foot-driven lever in particularly a kind of Folding Bicycle.

Background technology

The foot-operated of bicycle protruded to both sides, accounts for than large space when parking, though some Folding pedals are arranged at present, folding rear treadle still exceeds several centimetres in the crank outside.The foot-driven lever of now existing a kind of turnover, for example " prop stand for bicycle treadle folding " (Chinese patent bulletin: the mechanism that is showed CN 2647737Y), the turnover whole foot-operated folding in back of this mechanism has solved the foot-operated problem of protruding to both sides effectively in crank.But this mechanism is too complicated, the cost height, and this mechanism can not be used to have the pin axis to connect, and can not be used for left crank, so the existing market sales volume is few.

Summary of the invention

The prop stand for bicycle treadle turnover device that the utility model provides, it can solve existing same device complex structure, the problem that cost is high.

In order to address the above problem, prop stand for bicycle treadle turnover device of the present utility model, it includes the axis and the foot-driven lever of bicycle, on described axis, be fixedly connected with the treadle seat, described foot-driven lever is connected on this treadle seat by hinge axis, on described foot-driven lever, finger is housed, on described treadle seat, is provided with the bayonet socket that finger is pegged graft.

Hinge axis connecting bore on the above-mentioned treadle seat can be provided with the axis connecting bore and be communicated with, under this structure, one side of described hinge axis is provided with the inclined-plane that is provided with its axis tilt, and described axis is that the inclined-plane crimping by pin joint plane on it and described hinge axis is fixed on the described treadle seat; The bayonet socket that the described finger that is located on the treadle seat is pegged graft has two, and they are located at the both sides of described pan outside symmetrically.Hinge axis connecting bore on the above-mentioned treadle seat also can be arranged to and the disconnected structure of axis connecting bore, and under this structure, the hinge axis connecting bore on the described treadle seat is located at a side of axis connecting bore; The bayonet socket that the described finger that is located on the treadle seat is pegged graft has two, and they are located at the both sides of described pan outside symmetrically.Between above-mentioned foot-driven lever and the described finger spring can be housed; Described finger can be contained in outlet one end of the blind hole of described foot-driven lever, and described spring then is contained in the bottom of this blind hole; Can also be connected with the driving lever that an end stretches out described foot-driven lever side slotted hole in described finger side.

The bayonet socket that the alleged finger of the utility model is pegged graft is the spacing bayonet socket of the foot-driven lever both sides that are positioned at the treadle seat, and it can be the blind hole shape, also can pit, shape such as groove.

Owing to adopted such scheme, the utility model compared with prior art has following beneficial effect:

1, easy to manufacture, cost is low.It does not need directly to be connected with chain drum and direct connection on bicycle middle shaft, can exempt and chain drum bonded assembly labyrinth, so structure is simple relatively, manufacturing has relatively easily reduced manufacturing cost.

2, adaptation is wide.Because therefore this turnover foot-driven lever can not only can be used to be contained in the axis of bicycle chain drum one side by treadle seat direct connection on bicycle middle shaft, also can be applicable to be contained on the axis of the opposite side relative with the bicycle chain drum.

3, because this device can be contained in the two ends of axis, hinge axis is arranged on a side of axis, and the bayonet socket that is located at the finger grafting on the treadle seat can be provided with two, therefore, foot-driven lever is forwarded on the position that is positioned at treadle seat both sides, as long as stretcher in the conversion of foot-driven lever both sides, can be obtained pedaling of different length and steps on power arm, have the function of displacement foot-driven lever therefrom.

The specific embodiment

The utility model is described in further detail below in conjunction with the accompanying drawing example:

Fig. 1, in Fig. 2 and the example shown in Figure 3, this prop stand for bicycle treadle turnover device, it has and the axis 3 that has the bicycle same structure now, treadle seat 1 is equipped with in the outside that is positioned at chain drum 6 one sides at axis 3, the hinge axis connecting bore 1.2 that treadle seat 1 is provided with is connected perforation with axis connecting bore 1.1, one side of hinge axis 2 is provided with the inclined-plane that is provided with its axis tilt, axis 3 is by the pin joint plane on it and the inclined-plane crimping of hinge axis 2, the nut of having tightened the hinge axis 2 of pin effect can be captiveed joint treadle seat 1 with axis 3, the step of lining 9 withstands on the side of treadle seat 1, lining 9 also has the centering effect, and foot-driven lever 4 can rotate around lining 9 outer walls; Foot-driven lever 4 is connected on the treadle seat 1 by hinge axis 2, and finger 7 is housed on foot-driven lever 4, is provided with the bayonet socket 1.3,1.4 that two fingers are pegged graft on treadle seat 1, and they are located at the both sides of pan 1.2 outsides symmetrically.Finger 7 and spring 8 are to be contained in the blind hole of foot-driven lever 4, and finger 4 is contained in outlet one end of the blind hole of foot-driven

lever

4, and 8 bottoms that are contained in this blind hole of spring also are connected with the driving lever 5 that an end stretches out foot-driven lever 4 side slotted holes in the side of finger 7.

In the example shown in Figure 4, in the treadle seat 10 of this prop stand for bicycle treadle turnover device, the connecting bore of hinge axis 11 is disconnected structure with the connecting bore of axis 13 also, the axle body of hinge axis 11 is a column construction, the cross-sectional plane of the coupling end of axis 13 is square, before be plugged in the square hole of treadle seat 10, other structure is identical with the example shown in Fig. 1 to 3.
