Detailed Description

As shown in fig. 1, 2 and 3, the improved bicycle pedal comprises a pedal body 1, wherein the pedal body 1 is U-shaped, through holes are transversely formed in the upper ends of two side plates of the pedal body 1, bearings 2 are respectively arranged in the two through holes, a hollow tube 3 is arranged between the two bearings 2, two ends of the hollow tube 3 are respectively arranged in the bearings 2, a main shaft 4 is arranged in the hollow tube 3, the main shaft 4 penetrates through the bearings 2 and the hollow tube 3, and the main shaft 4 is fixed on the pedal body 1 through a nut, so that the pedal body 1 can rotate along the main shaft 4.

The rear end of the bottom plate of the pedal body 1 is provided with a lock catch plate 5, and the lock catch plate 5 can be movably clamped with a corresponding lock shoe.

The through-hole of 2 outer ends of bearing is provided with the internal thread, the internal thread is used for the cooperation to correspond the rand that has the external screw thread fixed, the rand passes through threaded connection and fixes bearing 2 in the through-hole.

A circular through hole 6 is formed in the middle of the bottom plate of the pedal body 1, and the circular through hole 6 is used for being matched with a circular protrusion of a corresponding lock shoe.

The lock catch plate 5 is hinged to the pedal body 1, a torsion spring 7 is arranged between the hinged shaft and the pedal body 1, and the lock catch plate 5 corresponds to a locking inclined plane at the bottom of the clamping lock shoe under the action of the torsion spring 7.

The end part of the main shaft 4 is provided with a threaded end, and the threaded end penetrates through a nut and then is connected with a crank corresponding to the bicycle.

The present invention will be described in detail with reference to the following examples.

The invention discloses a U-shaped pedal body, two ends of the pedal body are provided with two bearing positions, the outer sides of the two bearing positions of the pedal body are both provided with internal threads, after an outer bearing and an inner bearing are respectively and correspondingly arranged in the two bearing positions of the pedal body, a threaded ring is respectively screwed into the internal threads of the pedal body until the end surface of the threaded ring is contacted with the outer ring of the bearing and locked, a hollow circular tube is placed between the two bearing inner rings, after the installation step is completed, the threaded end of a main shaft passes through the outer bearing inner ring and the hollow circular tube along the axial lead and then penetrates out of the inner bearing inner ring, at the moment, a nut is screwed into the threaded end of the main shaft until the end surface of the nut is contacted with the end surface of the inner bearing inner ring and locked, at the moment, the end surface of the main shaft is contacted with the end surface, thus, the assembly of the axial center portion of the pedal is completed.

And the threaded end of the main shaft is screwed into the internal threaded hole of the crank until the end surface of the nut is contacted with the end surface of the crank to be locked, and the pedal and the crank are installed at the moment, so that the pedal can rotate freely around the main shaft.
