Description
Technical field
The present invention relates to a kind of bicycle assembly parts, particularly relate to a kind of reflexibie bicycle pedal.
Background technology
At present, after bicycle assembling, pedal is connected with crank, and the outer end of pedal is relatively wide, the most unfavorable to reducing packing measurement(s).To this end, some bicycle pedals use folding mode.Chinese patent " foldable bicycle pedal " (application number: 02261933.X) discloses a kind of folding pedal, and its principle is: pedal is made up of upper and lower two panels, upper and lower pedal
Middle part is articulated with on axostylus axostyle, the pin parallel with axostylus axostyle is had in axle sleeve the inner, in a state of use, pedal inside end is against on pin up and down, is hinged with the connecting rod being hinged, has spring between upper and lower two panels pedal and connecting rod between upper and lower two panels pedal, spring makes upper and lower pedal can maintain folding or open mode, there is lever between pedal and connecting rod, promote lever to the left and right, can enter
Row folds or opens.After the pedal of this patent folds, effect is obvious not, and pedal still occupies certain width, lacks practicality, and structure design is more complicated, and connector used is more, and manufacturing cost is higher.
Summary of the invention
Instant invention overcomes the deficiencies in the prior art, it is provided that a kind of simple in construction, can by pedal folding turn 90 degrees, can be by the pedal of turning back of the reduced width of pedal to minimum state.
For reaching above-mentioned purpose, the technical solution used in the present invention is: a kind of reflexibie bicycle pedal, it includes pedal main body, the vertical outside crank connecting described pedal main body and the crank of the described outside crank of connection, described crank is removably attached on the axis of bicycle, it is characterised in that: described outer crankshaft is to being rotatably connected on described crank.
In a preferred embodiment of the present invention, farther include described crank and include orthogonal connecting portion and fixed part, described fixed part is removably attached on the axis of described bicycle, the free end top of described connecting portion offers blind hole, and the free end of described outside crank is rotatably arranged in described blind hole.
In a preferred embodiment of the present invention, farther including to be circumferentially with stopper slot along it on the free end outer wall of described outside crank, described crank is provided with spacing hole, is provided with resilient key in described spacing hole, and the top of described resilient key is pressed in described stopper slot.
In a preferred embodiment of the present invention, farther include described stopper slot a length of described outside crank girth 1/4th.
In a preferred embodiment of the present invention, farther include described outside crank outer wall and be radially provided with fixing hole, being provided with stage clip in described fixing hole, described stage clip one end connects alignment pin, and on described crank, corresponding described fixed hole position installs and is equipped with hole, a location.
In a preferred embodiment of the present invention, farther include the described alignment pin diameter near one end of described stage clip the diameter more than its other end.
The present invention solves defect present in background technology, the pedal of the present invention can 90 degree turn back, packing measurement(s) can be reduced by the reduced width of pedal to minimum state, reduce manufacture and cost of transportation, convenient and practical.

Detailed description of the invention
Presently in connection with drawings and Examples, the present invention is further detailed explanation, and these accompanying drawings are the schematic diagram of simplification, and the basic structure of the present invention is described the most in a schematic way, and therefore it only shows the composition relevant with the present invention.
As shown in Figure 1, a kind of reflexibie bicycle pedal, it includes pedal main body 4, vertical connecting legs is pedaled the outside crank 3 of main body 4 and connects the crank 1 of outside crank 3, crank 1 is removably attached on the axis 2 of bicycle, crank 1 with in structure and this area of that one end that axis connects commonly the structure of crank identical；Outside crank 3 is axially rotatably connected to
On crank 1.
As the preferred embodiment of the present invention, crank 1 includes orthogonal connecting portion 11 and fixed part 12, and the structure of the structure of fixed part 12 crank common with this area is identical, and fixed part 12 is removably attached on the axis 2 of bicycle；The free end top of connecting portion 11 offers blind hole 111, and the free end of outside crank 3 is rotatably arranged in blind hole 111.
Further, as shown in Figures 2 and 3, along its circumferentially disposed stopper slot 31 on the free end outer wall of outside crank 3, crank 1 is provided with spacing hole (not shown), arranging resilient key 5 in spacing hole, resilient key 5 is standard component customary in the art, and the top of resilient key 5 compresses in stopper slot 31.
Preferably, 1/4th of a length of outside crank 3 girth of stopper slot 31, i.e. outside crank 3 can make 90 degree of rotations on crank 1, and resilient key 5 can limit outside crank 3 and not be pulled out, and prevents pedal from loosening in use.
As the preferred embodiment of the present invention, can radially arrange fixing hole (not shown) on the outer wall of outside crank, arrange stage clip 7 in fixing hole, stage clip 7 one end connects alignment pin 6, and on crank 1, the position of corresponding fixing hole arranges hole 8, a location.Further, the alignment pin 6 diameter near one end of stage clip 7 is more than the diameter of its other end, outside alignment pin 6
The hole, location 8 that end (that one end that i.e. diameter is little) is pushed down on crank 1 in the effect of stage clip 7, thus pedal main body 4 is fixed on above operating position, prevent pedal from loosening in use further.
The pedal of the present invention is compared with pedal conventional in the art, it is improved by, the crank connecting pedal is set to two parts, i.e. crank 1 and outside crank 3, crank 1 is square, and one end of crank 1 is connected on bicycle middle shaft, and outside crank 3 then inserts the other end of crank 1, make outside crank 3 can rotate 90 degree in crank 1, use keeper location.Owing to pedal is attached on outside crank 3, pedal rotates 90 degree also with outside crank 3, thus by the reduced width of pedal to minimum state.
The pedal of the present invention can 90 degree turn back, can by the reduced width of pedal to minimum state, bicycle vanning time, as shown in Fig. 4, pedal is inwardly rolled over and turn 90 degrees loading；During use, as shown in Fig. 5, pedal is outwards rolled over and turn 90 degrees.
The pedal structure of the present invention is simple, and easy for installation, low cost of manufacture, the size after folding is less, reduces the size of vanning, reduces cost of transportation simultaneously.
Desirable embodiment according to the present invention is enlightenment above, and by above-mentioned description, related personnel can carry out various change and amendment completely in the range of without departing from this invention technological thought.The content that the technical scope of this invention is not limited on specification, it is necessary to determine technical scope according to right.
