New description · [New technical field] This creation is a technical field of the pedal shaft. [Prior Art] According to the conventional pedal structure, please refer to the first figure, which mainly includes a pedal body 1, a shaft rod 2 and a crank 3, wherein the shaft hole 1 of the pedal body 1 is inside. The ball set 1 1 and the shaft rod 2 are arranged, and under the pedal body 1 in which the shaft rod 2 is assembled, a balance iron 18 is arranged to serve as the pedal body 1 when the pedal body 1 is unstressed. The pedal body 1 can be freely rotated according to the shaft rod 2 when the force is stepped on; and the two ends of the shaft rod 2 are divided into the first thread 2 〇 And a second thread 2 1 , and an abutting portion 2 2 is formed on a side of the first thread 20 , and a shaft 2 3 is formed between the abutting portion 2 2 and the second thread 2 1 to cause the crank 3 The threaded portion 30 and the threaded portion 3 5 Q of the tightening screw head 35 can be respectively assembled on the first thread 2 〇 and the first thread 2 1 to reach the pedal body 丨 can be the shaft rod 2 The basis for the rotation of the wheel center; thus, although it can achieve its purpose of creation, but in assembly or use, W will have the following problems: due to the crank and shaft rod The combination is achieved by the screwing of the thread. However, when the pedal is used, the crank and the shaft rod _ the thread is loosened due to the vibration of the pedaling, which is even more severe. [3 Sen, it will cause the crank and the shaft to fall off during normal use, which will cause accidental danger to be a major problem. In view of this, the creator is actively developing research, and in order to improve the lack of the above-mentioned pedal construction, the creator has been developing and designing this creation after long-term research and experiment with the experience of being engaged in the manufacture of such products for many years. The foot pedal shaft structure can benefit all consumers and manufacturers. [New content] The main content of the foot pedal shaft structure of the present invention is to provide a locating portion of the side end surface of the abutment portion of the shaft rod to form a tighter relationship between the crank side surfaces when locked. The card can be used in a snap-to-bit relationship, so that the locking between the crank and the shaft rod can be made more tight and not loose, so as to prevent the separation between the shaft rod and the crank when the pedal is used. The accidental injury occurs, and the safety of the user can be greatly improved as a progressive effect. [Embodiment] The present invention relates to a pedal shaft rod structure, please refer to the second to fourth figures, which includes a body 5 which can be divided into a first thread portion 5 〇, abutting a portion 5 1 , a body 5 2 and a second threaded portion 5 3 , wherein the first threaded portion 50 and the first threaded portion 53 are respectively located at two ends of the body 5 and are at the first threaded portion 5 The abutting portion 5 1 is formed on the side, and the shaft-shaped shaft 5 2 is formed in the abutting portion 5 1 to the second threaded hopper 5 3 j; further, the side end surface (4) of the abutting portion 51 has a plurality of surfaces (4) the positioning portion 5 1 Q, so that the first thread portion 5 〇 and the screw portion 6 of the crank 6 are tightly screwed together, so that the side surface of the crank M315692 6 and the abutting portion 5 1 The positioning portion 5 1 forms a tighter card-biting partner between the turns; and the positioning portion 5 1 is arranged on the side surface of the abutting portion 51 in a meandering manner, and the positioning portion 5 1 0 is used to invert the window. The shape, the bump shape, the convex strip shape, etc. are optimal; when the shaft rod 5 penetrates into the shaft hole 7 踏板 of the pedal 7, it is screwed to the second shaft rod 5 by the tightening nut 8 Threaded part 5 3, and can be rubber shaft The lever 5 is actually assembled on the shaft hole 70 of the pedal 7 as a basis for rotation when the pedal pedal 7 is rotated; at this time, the first thread portion of the shaft rod 5 that has been assembled on the pedal 7 is further 50 is directly screwed onto the threaded portion 60 of the crank 6, and the first threaded portion 50 of the shaft rod 5 can be surely formed into a tight fit with the threaded portion 6 of the crank 6 The side surface of the crank 6 can be engaged by the positioning portion 5 1 柢 of the abutment portion 5 1 of the shaft rod 5 to increase the locking tightness between the crank 6 and the shaft rod 5, so that the crank 6 can be surely The locking between the shaft rods 5 is more tight and there is no looseness. When the pedaling is used, it can ensure that the shaft rod 5 and the crank 6 _ are never separated by the vibration of the pedaling. Accidental injuries occur, and those who greatly improve the safety and life of the user can be achieved. In summary, the foot pedal shaft structure of this creation does have an unprecedented innovative structure. It is not found in any publication, and there is no similar product on the surface. Therefore, its novelty should be Undoubtedly. In addition, the unique characteristics and functions of this creation are far from comparable to those of the old ones, so it is indeed more progressive than the customary ones, which is in line with the requirements of the application for new patents in China's patent law. File a patent application.
