Description of the Invention: [Technical Field] The present invention relates to an anti-rotation structure of a bicycle assisted stepping rod, and the bicycle is often fitted with an auxiliary stepping lever on the mandrel of the wheel, and the auxiliary stepping rod It can be used with bicycles for performances (4). This is a research and development designer for the help of the pedals. _ [Previous technology] Bicycles are currently the most suitable means of transportation and short-distance transportation, and the power of bicycles is mainly The pedaling method 'snaps the chain with the interlocking gear on the wheel to make the rear wheel have the power of advancement, and with the rotation of the front wheel, the sisters on both sides of the front and rear wheels of the bicycle will often be equipped with auxiliary The pedals are provided to provide bicycles with different and diverse stunt performances. As shown in Figures 5 and 6, the bicycle frame (10) is provided with a recording (10) number of flowers (2 inches) between the forks (1). The two sides of the knife extend out of a mandrel (2)) both ends of the 'mandrel (2)) and each lock with a nut (3〇), and the outer side continues to provide the screw of the auxiliary step (4〇). The auxiliary stepping rod (40) is usually formed by extrusion of aluminum, and the outer peripheral edge is pressed with a non-slip pattern, and the center of one end of the plane (41) is recessed with a screw hole (42), and the screw hole (42) is Set, so that the auxiliary pedal (4〇) can be locked on the two ends of the hub (2〇) to provide a stunt performance for the bicycle. When the auxiliary pedal (40) is used for performances, it is often the second person stepping on the auxiliary pedal (40) to perform with the performance, or the auxiliary pedal (4〇) will touch the stunt behavior of the 1314116 ground when the bicycle turns. The miscellaneous action will rub to the lion pedal (10)). When the friction is clockwise, it will rotate the auxiliary pedal (10) that has been locked, so that the auxiliary _ (10) is locked too tightly to disassemble, even tight. Part (1) The doubt that the fork of the gold material (11) is deformed, and when the friction of the auxiliary pedal (10) is counterclockwise, the auxiliary pedal (10) will loosen, which may cause the danger of performance, and even record The second person standing on the auxiliary step (10) is at risk of falling.疋 ' ' 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本Point: The self-propelled car assisted stepping rod structure, when the auxiliary lining pole makes the secret performance, the auxiliary pedal rod that has been locked already, and the help of the stepping pole, the detachment will be too tight, and will not be pregnant. When you are loose, you will be more worried about the money-making doubts, and this will cause danger. This is the technical problem to be solved. Technical features to solve the problem: Lin provides a kind of anti-rotation structure for bicycle lion pedals. After the bicycle and auxiliary step # set, the continuation of the nut is set on the mandrel. Among them, 6 1314116 The side of the department is set to #—to match the inclined surface, the male hub of the flower hub is set on the frame and the auxiliary stepping rod is a long hollow tube body. The outer riding pressure is provided with a light grain road, and the inner end portion is provided with a inclined matching inclined surface. The slanting financial center and the vertical _ stepping rod are provided with a perforation, and the outer side of the auxiliary stepping rod is provided with a counterbore, which is penetrated with the perforation, and the l hole is larger than the perforation, and the bicycle Assisting struts are formed by the above structure The anti-rotation structure. Compared with the efficacy of the prior art: This (four) is a hybrid bicycle _ _ _ structure, the more assisted stepping rod is the nut with the __ 're- _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The rod is axially locked to the mandrel, and the rotation direction of the auxiliary stepping rod can be fixed by the use of the two matching inclined surface, so that the _ pedal can only be fixed in the direction of the fork and the structure of the structure is completely worried. The use of the lion's pedal will be tightened or loosened by the lock s, and the safety of use is better. [Embodiment] In order to enable the reviewing committee to have a more in-depth understanding and understanding of the purpose, features and effects of the present invention, the following (10) in conjunction with the [simple system] detailed as follows: First, please first by the first and second As shown in the figure, the bicycle frame (10) is provided with a flower hub (10) between the forks (51), and a mandrel (61) is respectively extended on both sides of the flower hub (10), and an auxiliary pedal is provided on the outer side. After the sleeve is set (10), 1314116 is screwed onto the mandrel (61) by the nut (10). Wherein, the outer side of the fork portion (51) of the frame (50) is provided with a matching inclined surface (52), and the spindle (61) of the flower hub (60) is sleeved on the fork portion (51) of the frame (50). The auxiliary stepper (go) is a hollow long tube body, and the outer circumference is pressed with a non-slip texture, and the inner end portion is provided with a sloped special inclined surface (81) 'the center of the matching slope surface (81) and the vertical auxiliary stepping rod ( Go) is provided with a perforation (82), and the outer side of the auxiliary step (80) is provided with a counterbore (83) which is continuous with the perforation (82) and the counterbore (83) is larger than the perforation ( 82). Repair the combination of the structure, as shown in Figure 3, 'flower hub (60) is erected between the forks (51) of the frame (5〇) and is surrounded by the mandrel (61) from both sides of the fork (51) Extending, the auxiliary stepping lever (8〇) is placed on the opposite ends of the mandrel (61) by the perforation (82), and is matched with the inclined surface of the inclined surface (81) and the frame (50) (52) Flat fit, so that the auxiliary step (8〇) is in line with the mandrel (61), and the mandrel (61) is extended by the counterbore (83) of the auxiliary step (8〇), the nut (70) The mandrel (61) is screwed into the counterbore (83) of the auxiliary step (80) to lock the auxiliary step (80) to the mandrel (61) and to match the bevel (52) (81) They are used in conjunction with each other to assist in the setting of the Lut Teng Cup (8〇) and to provide a stunt show for bicycles. As shown in Figures 3 and 4, the auxiliary pedal (80) is internally locked by a nut (7〇), and when the auxiliary pedal (80) is to be rotated, the auxiliary pedal (8〇) is The mating faces (52) (81) are brought into abutment so that the abutting faces are not in the same vertical direction as the mandrel (61) and thus cannot be rotated. By the above specific structure, the following benefits can be achieved: the auxiliary pedal (80) is internally locked by the nut (10), and the matching inclined surface of the auxiliary step (10) (10) 8 1314116 and the fork (51) The matching inclined surface (52) is abutted, so that the auxiliary stepping rod (80) is axially locked to the mandrel (61), and the rotation of the auxiliary stepping rod (8〇) can be fixed by the use of the two matching inclined surface (52X81). The direction is such that the auxiliary pedal (80) can only be fixed in the direction and the other part (51). The design of the structure is completely worrying about the tighter or looser situation in which the auxiliary pedal will be locked during use. Occurs, the security of use is better.
