Pedal bearing structure

The novel creation is related to the bicycle pedaling component, and particularly refers to a pedal bearing structure which has the characteristics of simple assembly and low production cost.

The running power of the bicycle relies on the rider's feet to push the force and drive the wheel set forward through the transmission system. It can provide short-distance travel without additional power components. The bicycle is quite popular among students and short-distance commuters. Favor. Moreover, riding a bicycle can not only enjoy the natural scenery along the way, but also properly experience the local culture and folk customs. In recent years, it has become a popular choice for leisure and entertainment.

Since the pedals of bicycles need to withstand the constant force exerted by the riders, the development of the pedal-related development has continuously designed a variety of new forms of pedals, such as increasing the strength of the pedaling, lightweight structure or easy assembly. A wide variety of demand groups on the market. For example, the improved structure of the bicycle pedal spindle of the Republic of China Patent No. M436634 is such that the pedal is provided with a spindle that can rotate relative to the pedal, and one end of the spindle is a connecting end, and an external thread is provided on the peripheral side surface of the connecting end to be screwed. In the crank of the bicycle, the other end of the mandrel is end and provided with an internally threaded hole, and the bolt is screwed to the internally threaded hole, so that the pedal is restricted by the bolt head, and the pedal is prevented from coming out toward the outside of the end of the mandrel.

The above-mentioned manner of restricting the positioning of the pedal to the mandrel is quite common. However, in actual use, the end of the mandrel needs to be additionally machined with an internally threaded hole, and two processes such as opening and threading are required, and the mounting bolt is used to limit the positioning pedal. Work on the mandrel, in mass production Excessive processing and assembly operations are missing from increasing the cost of the operator and wasting too much assembly time. In addition, the mandrel is subjected to the force that the rider is constantly stepping on, so the manufacturer also heat-treats the mandrel so as to increase the strength of the mandrel.

In addition, there is a general method of using the positioning pedal on the mandrel, which mainly applies an external force at the end of the mandrel through the pedal, and causes the head end to produce an enlarged outer diameter type. The method can only be applied to mandrels that have not been heat treated, so such pedal mandrels are quite limited in durability.

In view of this, the new creator of this case can use the heat-treated mandrel for the development and design of the pedal related to the above-mentioned missing, and the pedal can be stably fixed on the mandrel without the screw-locking related components. The assembly process of the pedal and the mandrel can be completed by too many processing processes, so that the assembly is simple and the production cost is low, and the utility model becomes a practical and excellent new creation.

The main purpose of this creation is to provide a pedal bearing structure with simple assembly and low production cost.
