Abstract
The utility model relates to the technical field of bicycle components, in particular to a bicycle rotary lengthening power-assisted pedal rod and a pedal rod body; one end of the pedal rod body is a right-angle corner and is provided with a hole body, and a turntable mounting shaft is rotatably arranged in the hole body at the right-angle corner of the pedal rod body; the other end of the pedal rod body is provided with a hole body, and a pedal mounting shaft is rotatably arranged in the hole body at the other end of the pedal rod body. According to the utility model, the pedal can shift the ankle under the action of the pedal force, friction can not occur to the ankle joint when the pedal is operated, and the force generated by the pedal force can be larger than that of a traditional straight rod or an arc rod, so that the blind spot can be naturally crossed, and the labor-saving effect can be achieved. The pedal rod body is more labor-saving when riding because the bearing force of the pedal rod body is increased in the direction away from the center shaft of the bicycle turntable and the force arm of the increased pedal force is also increased, and meanwhile, the corner shape of the pedal rod body is a right angle, so that the cost is lower when in production.
Description
Technical Field
The utility model relates to the technical field of bicycle components, in particular to a bicycle rotary lengthening power-assisted pedal rod.
Background
The bicycle pedal crank is one of key parts of bicycle power system, the existing crank is straight shank of "straight" shape, in the straight shank while running, the crank pedal shaft has two blind spots of highest point and lowest point in the course of moving from highest point to lowest point, the moment is from blind spot of highest point to increase downwards sequentially, the direction of foot pedal of the person is perpendicular to direction of the crank body of rod while reaching the horizontal position, the moment is largest, then progressively smaller, then to another moment blind spot of lowest point, in this course, the change of moment is relatively great, because of existence of two blind spots, more laborious while riding bicycle, especially it is more laborious to pedal straight shank while climbing or riding against wind
Accordingly, one skilled in the art would be able to provide a bicycle swivel extension booster pedal lever that solves the above-mentioned problems associated with the prior art.
Disclosure of Invention
In order to solve the technical problems, the utility model provides:
a bicycle rotary lengthening booster pedal rod and a pedal rod body; one end of the pedal rod body is a right-angle corner and is provided with a hole body, and a turntable mounting shaft is rotatably arranged in the hole body at the right-angle corner of the pedal rod body; the other end of the pedal rod body is provided with a hole body, and a pedal mounting shaft is rotatably arranged in the hole body at the other end of the pedal rod body.
Preferably: the pedal rod body is fixedly assembled at the circle center of the bicycle turntable through the turntable mounting shaft.
Preferably: the pedal shaft is rotatably arranged on the inner side of the pedal mounting shaft of the pedal rod body.
Preferably: the pedal shaft is rotatably provided with a pedal body outside, and the pedal body is rotatably arranged on the pedal rod body through the pedal shaft.
Preferably: the shape of the upper rotary disc mounting shaft of the pedal rod body is provided with two corners, and the corners are 90 degrees.
The utility model has the technical effects and advantages that:
according to the utility model, the pedal can shift the ankle under the action of the pedal force, friction can not occur to the ankle joint when the pedal is operated, and the force generated by the pedal force can be larger than that of a traditional straight rod or an arc rod, so that the blind spot can be naturally crossed, and the labor-saving effect can be achieved. The pedal rod body is more labor-saving when riding because the bearing force of the pedal rod body is increased in the direction away from the center shaft of the bicycle turntable and the force arm of the increased pedal force is also increased, and meanwhile, the corner shape of the pedal rod body is a right angle, so that the cost is lower when in production.

Detailed Description
The utility model will be described in further detail with reference to the drawings and the detailed description. The embodiments of the utility model have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the utility model in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments were chosen and described in order to best explain the principles of the utility model and the practical application, and to enable others of ordinary skill in the art to understand the utility model for various embodiments with various modifications as are suited to the particular use contemplated.
Examples:
referring to fig. 1 to 3, in this embodiment, a bicycle swing lengthening power assisting pedal lever and a pedal lever body 1 are provided; one end of the pedal rod body 1 is a right-angle corner and is provided with a hole body, and a turntable mounting shaft 2 is rotatably arranged in the hole body at the right-angle corner of the pedal rod body 1; the other end of the pedal rod body 1 is provided with a hole body, and a pedal mounting shaft 3 is rotatably arranged in the hole body at the other end of the pedal rod body 1; the pedal rod body 1 is fixedly assembled at the circle center of a turntable of the bicycle through a turntable mounting shaft 2; a pedal shaft 4 is rotatably arranged on the inner side of the pedal mounting shaft 3 of the pedal rod body 1; the pedal shaft 4 is externally rotatably provided with a pedal body 5, and the pedal body 5 is rotatably arranged on the pedal rod body 1 through the pedal shaft 4; the shape of the pedal rod body 1 at the position of the turntable mounting shaft 2 is provided with two corners, and the corners are 90 degrees;
the pedal body 1 and the turntable mounting shaft 2 are arranged at two right angles, the right angles are arranged at the two right angles, when the pedal reaches the moment change busy point in the running process of the bicycle, the pedal can shift the ankle under the action of the pedal force, the ankle joint can not generate friction when the pedal is operated, the force generated by the pedal force can be larger than that of a traditional straight rod or an arc rod, and the blind point is naturally crossed, so that the labor-saving effect is achieved. The pedal rod body 1 is stressed to be increased in the direction away from the center shaft of the bicycle turntable, and the force arm of the increased pedal force is more labor-saving during riding;
