Description

Large bearing pedal structure Technical Field The utility model relates to the field of pedals, in particular to a large-bearing pedal structure. Background The utility model provides a large bearing pedal structure, which is characterized in that a bicycle pedal is auxiliary equipment for people to pedal and provide forward power for the bicycle, bearings adopted on the bicycle pedal at present are small bearings, and in the pedal process, the feet possibly shake sideways or apply force obliquely, and the small bearings cannot effectively buffer the composite force and cannot rotate smoothly. Disclosure of utility model In order to overcome the defects in the prior art, the utility model provides a large bearing pedal structure, which can bear and effectively buffer lateral shaking or oblique force loss generated by a step in the pedal process by arranging the deep groove ball bearing, ensures smooth rotation, has a simple structure and good sealing performance, is suitable for being used as an outside bearing, and is convenient to install and maintain. Technical proposal The utility model provides a big bearing pedal structure, includes pedal body, pedal body's inside is provided with the entry end, the interpolation of entry end has the axle core, the rear end portion of axle core has set firmly deep groove ball bearing, the outside butt of deep groove ball bearing have threaded connection in the lock nut of entry end, lock nut with be provided with dustproof sealing washer between the axle core, dustproof sealing washer keep away from one side of entry end still is provided with and is located flaring spacing end on the axle core. Further, an internal thread is arranged at the port of the inlet end, and the lock nut is in threaded connection with the internal thread. Further, a step part for abutting against the deep groove ball bearing is arranged on the inner side of the internal thread. Further, a metal ring sleeved on the shaft core and in interference fit with the shaft core is further arranged in the inlet end. Further, the depth of the inlet end is also communicated with a shaft hole. Further, one side of the shaft hole, which is far away from the inlet end, is also abutted with a needle bearing which is rotationally connected with the shaft core. Advantageous effects Compared with the prior art, the utility model has the following beneficial effects: the deep groove ball bearing is arranged, lateral shaking or oblique force losing generated by the steps in the treading process can be borne and effectively buffered, the rotation smoothness is guaranteed, meanwhile, the deep groove ball bearing is simple in structure and good in sealing performance, is suitable for being used as an outer bearing, is convenient to install and maintain, the compactness of the needle roller bearing allows the shaft center to be designed to be finer, and the deep groove ball bearing with the large outer side can provide enough structural strength, and is light in weight and durable.
