Embodiment 1

[0028] Embodiment 1: as figure 1 , 2 As shown, a pedal mechanism for a bicycle for the disabled includes a central axis 18, a crank 14, a sprocket 15, a pedal body 1 connected to the end of a crank, and a main shaft tube 2 fixedly connected to the end of the crank. The main shaft tube 2 It is rotatably connected with the pedal body 1. The end of the other crank is connected with counterweight 16, and the weight of counterweight is greater than pedal body. The sprocket wheel 15 outer side is provided with sprocket cover 17, is fixed with first magnet 19 on the sprocket cover, and first magnet 19 is positioned at crank sprocket top and is close to the side of front wheel, is provided with on the crank that links to each other with pedal body and The first magnet magnetically attracts the second magnet 20 . The position symmetrical with the center of the first magnet is provided with a third magnet 21, and the crank connected to the counterweight is provided with a fourth magn...

Embodiment 2

[0030] Embodiment 2: The structure of this embodiment is basically the same as that of Embodiment 1, the difference is that, as Figure 8 As shown, the outer surface of the main shaft tube is covered with a sleeve body 13, and the outer surface of the main shaft tube and the sleeve body are connected by bearings. There are two pedal bodies, and both sides of the sleeve body are provided with pedal bodies. The bodies are connected by a rotating shaft 9, the rotating shaft is arranged vertically to the axis of the main shaft tube, the pedal body is rotationally connected with the sleeve body through the rotating shaft, and the upper and lower edges of the sleeve body near one end of the telescopic portion are provided with arc surfaces. Fixing holes 11 are arranged on the upper and lower ends of the casing, and the diameter of the fixing holes 11 is greater than or equal to the outer diameter of the fixing rod. Such as Figure 7 As shown, a positioning hole 10 is coaxially arra...

Abstract

The invention relates to a pedal, in particular to a pedal mechanism for a bike of a disabled person. The pedal mechanism for the bike of the disabled person comprises a center shaft, a crank sprocket, pedal bodies connected with the end part of one crank and a main shaft tube fixedly connected with the end part of the crank, wherein the main shaft tube is rotationally connected with the pedal bodies; the end part of another crank is connected with a balancing weight; the weight of the balancing weight is larger than that of the pedal bodies; the outside of the crank sprocket is sleeved with a sprocket cover; a first magnet is arranged on the sprocket cover and located on one side, close to a front wheel, of the upper part of the crank sprocket; a second magnet magnetically attracted with the first magnet is arranged on the crank connected with the pedal bodies; an included angle of the connection line between the first magnet and the center shaft axis and a horizontal line is 45-85 degrees. The pedal mechanism for the bike of the disabled person has the benefits that assistance can be provided for the disabled user, circling of pedals is facilitated and the like.

Description

technical field [0001] The invention relates to a pedal, in particular to a pedal mechanism for a disabled bicycle. Background technique [0002] Existing bicycles or spare pedals adopt integral design, are fixed on the crank connecting rod through the main shaft, pedals are used at both ends, and the weight of the two pedals is the same. When people with disabilities in legs or feet use this type of bicycle, they can only step on the pedals on one side. When the pedals go around half a circle near the rear wheel side, it is difficult for the pedals to rotate to the highest point. It is inconvenient for the disabled to pedal. When the pedals are at the highest point for pedaling, the pedaling pressure runs through the crank and faces the axis of the central axis, which is not convenient for the disabled to apply pedaling force. [0003] For example, the Chinese patent publication number is: CN101743160A, a bicycle pedal disclosed on June 16, 2010, which is composed of a wh...
