Bicycle pedal

The invention relates to a bicycle component, and more particularly to a bicycle pedal.

For example, refer to the Republic of China Patent No. M471419, which discloses a bicycle pedal for locking on a bicycle crank. The bicycle pedal includes a pedal body, a shaft, a self-lubricating sleeve, a bearing unit, and a a limiting unit, wherein the pedal body comprises a shaft hole disposed through the shaft, the inner end of the shaft is assembled on the crank, and the outer end portion is formed in the shaft hole, and the self-lubricating sleeve and the bearing unit are clamped The limiting unit is disposed between the shaft and the pedal body, and the limiting unit is disposed at an outer end of the shaft; thereby, the limiting unit prevents the pedal body from being disengaged from the shaft when the pedal body and the shaft move relative to each other in the axial direction.

However, in the bicycle pedal of the above-mentioned conventional bicycle, the shaft is tapered in order to be able to be assembled and stabilized, and is tapered away from the crank. However, such a tapered design often causes a problem that the center strength of the pedal body is insufficient, and Excessive components inside the pedal body also result in higher cost of the overall bicycle pedal.

In addition, when the bicycle pedal is to be assembled on the crank, or the part needs to be removed from the crank for replacement, it must be assembled and disassembled by a tool at the inner end of the crank, and the operation process is inconvenient, so Conventional bicycle pedals also have problems in assembly and disassembly.

To this end, how to provide an improved bicycle pedal to overcome the disadvantages of the conventional pedal described above is a problem that the relevant industry must solve at present.

In order to solve the above problems, the present invention provides a bicycle pedal having a straight cylindrical shape to enhance the strength of the pedal body, and the pedal body can be easily assembled and disassembled on the crank of the bicycle.

To achieve the above object, the bicycle pedal of the present invention is rotatably mounted to a crank of a bicycle, the bicycle pedal system comprising: a pedal body having a shaft hole transversely extending through the two ends of the pedal body; and an axial center a straight cylindrical shape, inserted in the shaft hole, and having a first end and a second end, wherein the first end is screwed to the crank, and the second end has a stop portion against the outer edge of the pedal body, and The pedal body is rotatable relative to the axis, and the second end has a tool drive portion.

Wherein, the inner edge of the shaft hole has an elastic member, and the elastic member has a through hole for the shaft to be inserted.

Wherein, the elastic element can be a spring, and the shaft is in contact with the elastic element in multiple points.

The utility model further comprises an anti-wear sheet disposed on the first end for preventing the pedal body from rubbing against the crank.

Among them, the tool drive part is a hexagonal hole for a hex wrench to drive.

By the above, one of the efficacies of the present invention is achieved by a straight cylindrical shape of the axis which enhances the strength of the overall pedal body.

According to the above, the second aspect of the invention can be achieved by driving the tool drive portion of the second end of the shaft by a hex wrench, so that the first end of the shaft can be fastened to the crank or detached from the crank. Therefore, the bicycle pedal of the present invention has the advantages of convenient assembly and disassembly, and is convenient for the user to operate.

According to the above, the third aspect of the invention can be achieved. The invention has a wear-proof sheet sleeved on the first end of the shaft center, thereby preventing the wear-resistant sheet from being located between the pedal body and the crank, thereby preventing the pedal body from being Friction with the crank to reduce the problem of wear damage.

According to the above, the fourth aspect of the invention can achieve the effect that the inner edge of the shaft hole of the pedal body has an elastic element for the shaft to be inserted, thereby enabling the rider to shock and increase when riding the bicycle pedal. The effect of the cushioning force.

According to the above, the fifth aspect of the invention can be achieved by the arrangement of the elastic elements, the axial center and the elastic element can be in multiple contact, so that the elastic element can replace the traditional bearing, so that the components of the bicycle pedal of the invention can be compared. Knowing less, and thus reducing overall costs, is more economical.
