Connecting column is stated equipped with metal gasket, chamfering, the circumference of the connecting column are equipped between the inner wall and end face of the metal gasket
Face is equipped with the sleeving and riveting bulge loop formed by sleeving and riveting, and the inside of the sleeving and riveting bulge loop and the chamfering of metal gasket are pressed into contact with, institute
The outer end for stating connecting column is equipped with the rotation riveting bulge loop formed by rotation riveting, and the outer diameter of the rotation riveting bulge loop is greater than the outer of sleeving and riveting bulge loop
Diameter, one end on the support tube close to rotation riveting bulge loop are equipped with end cap.
After crank shaft is connect with pedal frame, metal gasket is inserted on connecting column, using sleeving and riveting machine be aligned connecting column outer end into
Row sleeving and riveting, then rotation riveting is carried out by end of the riveter to connecting column, to be located at metal gasket chamfering on connecting column surface
Sleeving and riveting bulge loop is formed, rotation riveting bulge loop is formed in connection column end, prevents from pedal frame in this way and crank shaft is detached from, eliminate
The technique that screw thread is processed on connecting column, eliminates nut, reduces manufacture, the assembly cost of pedal；In the long-term use,
Sleeving and riveting bulge loop can have corrosion etc., and metal gasket may be deviate from from sleeving and riveting bulge loop, even if sleeving and riveting bulge loop damages, metal gasket is de-
The limit of rotation riveting bulge loop is also suffered from after out, so as to guarantee foot-operated normal use.
Preferably, the both ends of the crank shaft are additionally provided with support sleeve, it is equipped with and turns between the support sleeve and support tube
Dynamic set.Steel ball in current zanjon ditch ball bearing is prone to wear, and service life is shorter, passes through support tube, support in this structure
Rotation connection between set replaces bearing, improves foot-operated service life.
Preferably, one end on crank shaft close to thread head is additionally provided with washer, the inner ring and crank shaft of the washer it
Between be equipped with inner seal ring, between the outer ring and support tube of the washer be equipped with exterior seal ring.Inner seal ring, external seal on washer
Waterproof and dustproof effect is enclosed, prevents outside moisture, dust from entering inside support tube, improves foot-operated service life.
Preferably, being equipped with nylon spacer, the periphery of the nylon spacer between the sleeving and riveting boss and rotation riveting boss
If being equipped with arterial highway O-ring.Nylon spacer can prevent extraneous solid particulate matter from entering in support tube；O-ring can prevent extraneous
Water, dust enter in support tube, to improve foot-operated service life.
Preferably, the inside of the nylon spacer is equipped with bushing, pressure spring is equipped between the bushing and nylon spacer.
When revolving riveting due to riveter, the distance between rotation riveting bulge loop and sleeving and riveting bulge loop for eventually forming are difficult to control, and pressure spring can be automatic
Distance difference is adapted to, guarantees the stability of nylon spacer, will not shake.
Therefore, the present invention, which has, reduces manufacturing cost, guarantees the more reliable and more stable beneficial effect of pedal frame, pedal axis connection
Fruit.
