New description: [New technical field] [0001] The present invention relates to a bicycle pedal mandrel structure, in particular to a mandrel structure with an auxiliary pedal rotating force, whereby the mandrel is provided Auxiliary rotation of Palin to achieve the above effects and increase the life of the mandrel. [Previous technology] [0002] According to the fact that oil prices have soared in the past two years, Taiwan’s big environment seems to be driving the bicycle trend, driving a new wave of ideas for environmental protection, energy conservation, health and Lohas. Bicycles for all ages and men and women. Leisure activities have become a prominent school; recently, on the streets, there have been more "cyclists", and Taiwan’s well-known bicycle companies have also actively promoted bicycles and challenges with the counties and municipalities. In the race, bicycle leisure sports have blossomed everywhere, and it has become a national sport in Taiwan. Whether the bicycle is used for leisure or transportation or competition, the bicycle industry is constantly improving the various components of the bicycle so that the bicycle can get better and better. Performance is the mission of the bicycle industry. [0003] The development of bicycles has been a hundred years old, and the structure has changed little, but the development of materials has not been consistent with the previous design, and the materials must be suitable. Generally, the pedal of the bicycle is connected to the crankshaft power rod through the mandrel, and the pedal is used to drive the bicycle traveler. The design of the traditional mandrel is roughly divided into the following types, as follows: [0004] As shown in the sixth figure, the mandrel (7) corresponds to the center hole (8 1 ) embedded in the pedal (8 Form No. A0101, page 3 / page 17 M381585), and Palin is provided at the front end (7) 1), for the pedal (8) to be rotated by the gravity of the foot, however, the front end Palin (7 1 ) lubricates, and the central part produces a dead angle friction phenomenon of the foot force, causing the mandrel (7) to be subjected to Loss and reduce life. Or a plastic ring (7 2) is placed on the central part of the mandrel (7) to produce the lubrication effect with the mandrel (7), but the plastic material has poor lubricity and cannot withstand too much external force, and is easily broken. Missing. [0005] As shown in the seventh figure, it is locked to a sleeve (82) at the center hole groove (8 1 ) of the pedal (8), and the mandrel (7) as described above is also assembled in the sleeve (82). Therefore, there are also the above-mentioned deletions. [0006] The reason is that the present creator has many disadvantages in the related field, in view of the fact that the existing bicycle heart shaft and the pedal are assembled and assembled with a dead angle of gravity applied by gravity, and the pedal rotation is not smooth, resulting in handling and the like. With the help of manufacturing and design experience and knowledge, and through many ingenuity, the R&D improvement of the mandrel and pedal combination is used to achieve higher practical efficiency. [New Content] [0007] The main purpose of the bicycle pedal mandrel structure of this creation is to make the pedal rotate smoothly and unimpeded, thereby increasing the service life of the mandrel; thereby providing the auxiliary rotation of the Palin on the mandrel to achieve The auxiliary pedal rotates the force of the mandrel structure. The purpose and function of the bicycle pedal mandrel structure of the present invention is achieved by the following techniques: Form No. A0101 Page 4 of 17 [0008] M381585 [0009] The mandrel is embedded in the pedal, embedded in the mandrel There is a main Palin for pedaling to generate a rotation, and the other end of the mandrel is correspondingly connected with the gear drive, wherein one or more auxiliary bottles are arranged on the shaft of the mandrel; In this way, the design of the auxiliary Palin makes the rotation of the pedal smoother, and the wear angle without the pressure of the foot force can greatly increase the service life of the mandrel. [0010] The bicycle pedal spindle structure of the present invention is further provided with a dustproof washer on the mandrel rod body, and the dustproof washer is correspondingly embedded in the slot of the center hole of the pedal, and mainly prevents impurities such as dust, soil and moisture from penetrating into the mandrel. In order to achieve good dustproof effect.
