Example 1:
referring to fig. 1, 2, 3 and 4, the labor-saving pedal device of the present invention includes a bracket 1 and a labor-saving device, wherein the labor-saving device is disposed at one side of the bracket 1, and the labor-saving device includes a support 11, a driving wheel 2, a limiting rail 21, an extension device 3, a driving arm 4 and a supporting rod 5.
The support 11 is arranged on the support 1, the extension device 3 is fixedly connected with the support 11, and the driving wheel 2 is sleeved on the support 11 and rotates relative to the support 11. The driving wheel 2 is provided with a limit rail 21, the supporting rod 5 moves along the limit rail 21, one end of the supporting rod 5 is hinged with the driving arm 4, and the other end of the driving arm 4 is hinged with the extension device 3. Preferably, the strut 5 is a telescopic rod. The length of the supporting rod extending out of the limit rail 21 can be effectively reduced by adopting the telescopic rod. Preferably, the length of the actuator arm 4 is greater than the length of the extension means 3.
Preferably, the extension means 3 are arranged between the transmission arm 4 and the transmission wheel 2. In this way the actuator arm can be rotated unobstructed outside the extension unit. Wherein, the articulated end of branch 5 and arm 4 is provided with running-board installation position 6, through the running-board of installing at running-board installation position 6, makes things convenient for the pedal.
Preferably, the limit rail 21 is a sleeve and/or a linear bearing. The relative sliding of the supporting rod and the limiting rail is conveniently realized. The invention is realized by adopting a mode of matching the sleeve with the linear bearing, namely the linear bearing is arranged in the sleeve, and the supporting rod moves along the linear bearing. Wherein, after the linear bearing damages, can conveniently change, and need not whole change spacing track.
Preferably, the two sides of the bracket 1 are respectively provided with a first labor-saving device and a second labor-saving device, and the first labor-saving device and the second labor-saving device are labor-saving devices. The first labor-saving device and the second labor-saving device which are positioned on the two sides of the bracket are respectively utilized to conveniently realize alternate labor-saving riding of the two feet. When one foot is forced, the other foot is not forced, and the riding mode of the bicycle in the prior art is the same as that of the bicycle in the prior art. Preferably, the first labor saving means and the second labor saving means share the stay 11. Preferably, the extension means 3 of the first and second labour saving means are at an angle of 180 °. The effect that one pedal is in front and the other pedal is in back is conveniently achieved.
