Abstract
The invention provides a length-adjustable pedal device, which comprises a middle shaft, a crank arm and a pedal, wherein one end of the crank arm is connected with the middle shaft; the other end of the crank arm is connected with the pedal; and the crank arm is of a telescopic structure. The telescopic structure comprises a fixed sleeve and a telescopic sleeve; the fixed sleeve is connected with the middle shaft; the telescopic sleeve is fixedly connected with the pedal; more than one first through hole is formed in the fixed sleeve; more than one second through hole is formed in the telescopic sleeve; the diameter of the telescopic sleeve is smaller than the diameter of the fixed sleeve; and the telescopic sleeve is inserted into the fixed sleeve and is fixed by passing screw bolts through the first through hole and the second through hole.
Description
Technical field
The present invention relates to electric automobiles, the foot pedal apparatus of a kind of adjustable length.
Background technology
At present, although the most of electric bicycle on market is provided power by storage battery, but still with foot-operated and chain,
In the case of storage battery does not has electricity, stepped on row by manpower, but due in the most of the time, electric bicycle by driven by power, and
And when riding, pedal rotates sometimes, in order to avoid having influence on the people that rides, so the crank arm at general pedal is shorter,
In the case of storage battery does not has electricity, ride the most painstaking.
Summary of the invention
Goal of the invention: the technical problem to be solved is for the deficiencies in the prior art, it is provided that a kind of scalable
The foot pedal apparatus of length.
In order to solve above-mentioned technical problem, the invention provides the foot pedal apparatus of a kind of adjustable length, including axis, song
Shaft arm and pedal, described crank arm one end connects axis, and the other end connects pedal, and described crank arm is Collapsible structure.
In the present invention, described Collapsible structure includes fixing sleeve and extension sleeve, and fixing sleeve is fixing connects axis, stretches
Contracting sleeve is fixing connects pedal, and described fixing sleeve is provided with more than one first through hole, and described extension sleeve is provided with
More than one second through hole, the diameter of described extension sleeve inserts solid less than the diameter of fixing sleeve, described extension sleeve
Determine sleeve and fixed through the first through hole and the second through hole by bolt.
In the present invention, described Collapsible structure includes fixing sleeve and extension sleeve, and fixing sleeve is fixing connects axis, stretches
Contracting sleeve is fixing connects pedal, and described fixing sleeve deviates from the port, one end of axis and is provided with groove, described groove port
Outer ring is provided with inc iron hoop, and described iron hoop includes the first port and the second port, described first port and the second port
On be equipped with through hole, the first port and the second port are bolted, and it is tight by iron hoop that extension sleeve inserts fixing sleeve
Gu.
Beneficial effect: 1, the present invention is provided with the crank arm of adjustable length, it is simple to adapt to the bicyclist of different lower limb length.
2, the invention provides the crank arm of a kind of adjustable length, in the case of electric bicycle does not has electricity, increase crank arm
Length, increases power arm, saves muscle power, conveniently rides.
Accompanying drawing explanation
With detailed description of the invention the present invention done below in conjunction with the accompanying drawings and further illustrates, the present invention above-mentioned or its
Advantage in terms of him will become apparent.
Fig. 1 is the structural representation of embodiment 1；
Fig. 2 is the structural representation of embodiment 2.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is elaborated.
Embodiment 1:
Such as Fig. 1, including axis 1, crank arm 2, pedal 3, fix sleeve the 4, first through hole 4a, extension sleeve 5
With the second through hole 5a, wherein crank arm 2 one end connects axis 1, and the other end connects pedal 3, and crank arm 2 includes fixing
Sleeve 4 and extension sleeve 5, the fixing axis 1 that connects of fixing sleeve 4, the fixing pedal 3 that connects of extension sleeve 5, described
Fixing sleeve 4 is provided with more than one first through hole 4a, and this embodiment the first through hole 4a is three, described telescopic
Cylinder 5 is provided with more than one second through hole 5a, and this embodiment the second through hole 5a is two, described extension sleeve 5
Diameter is less than the diameter of fixing sleeve 4, and described extension sleeve 5 inserts fixing sleeve 4 and by bolt through the first through hole
4a and the second through hole 5a fixes, and bolt can regulate extension sleeve 5 through different through holes and insert the deep of fixing sleeve 4
Degree.
Embodiment 2:
Such as Fig. 2, including axis 1, crank arm 2, pedal 3, fix sleeve 4, extension sleeve 5, groove 6, first
Port 7a, the second port 7b and through hole 8, crank arm 2 one end connects axis 1, and the other end connects pedal 3, crank arm
2 include fixing sleeve 4 and extension sleeve 5, and fixing sleeve 4 is fixing connects axis 1, and extension sleeve 5 fixes connecting pin
Pedaling 3, the port, one end that described fixing sleeve 4 deviates from axis 1 is provided with groove 6, and at described groove 6, port outer ring sets
