Problems solved by technology

[0002] Due to the limitation of the pedaling position of the existing ordinary bicycles, the length of the single-arm lever used to connect with the pedals on the chain plate is relatively short, which is not very labor-saving.
Chinese patent ZL200620158888.2 discloses a labor-saving transmission rod for bicycles. Because the connection between the transmission rod and the first crossbar in the "Z"-shaped connecting rod is a rotational connection, the length of the transmission arm cannot be increased, so labor-saving cannot be achieved.

Embodiment 1

[0024] like figure 1 , Image 6 As shown, the bicycle labor-saving device of the present invention includes a transmission rod 1, a pedal or handle device connection 2, and a "Z"-shaped connecting rod 3. One end of the transmission rod is connected to the pedal or handle device 2, and the other end is connected to the "Z" shape. The connecting rod 3 is connected by a flywheel structure; the "Z" shaped connecting rod 3 includes a pair of parallel cross bars 31, 32 and a vertical rod 33 fixed between the two cross bars, wherein the first cross bar 31 and the transmission rod 1 It is connected by a flywheel structure (it belongs to the principle of the ratchet mechanism, when the pedal device or the handle device drives the transmission rod to rotate forward, it can drive the first cross bar 31 to rotate forward, if the pedal device or the handle device reverses, it cannot drive the first cross bar 31). The cross bar 31 rotates, that is, the transmission rod is idling), and the ...

Embodiment 2

[0032] like figure 2 As shown, the difference between embodiment 2 and embodiment 1 is: the pedal or handle device 2 is rotationally connected with the transmission rod 1 through the connecting rod 4, and the pedal or handle device 2 includes a connection rod connected to one end of the connecting rod 4 pedal or handle 22, a guide rod 23 vertically fixedly connected with the other end of the connecting rod 4, one end of the guide rod 23 is fixedly connected with the shaft 7 of the bicycle central shaft 6; the axle sleeve and the shaft of the bicycle central shaft 6 7 are rotationally connected, and their axes are parallel to the axis of the connecting rod 4.

[0033] The shaft rod 7 of the bicycle center shaft 6 is connected to the guide wheel 8 in rotation.

[0034]In order to make it easier for people to step on and drive by alternating left and right feet like using an existing ordinary bicycle, the other end 71 of the shaft rod 7 of the bicycle central axis 6 is fixedly ...

Embodiment 3

[0036] like image 3 As shown, the difference between embodiment 3 and embodiment 2 is: the pedal or handle 22 is fixedly connected to one end of the connecting rod 4 through the swing arm 21, and the pedal or handle 22 can perform circular motion around the axis of the connecting rod 4 . In this way, the transmission arm from the pedal or the handle to the axis of the power shaft is extended by the swing arm 21, which saves more effort in use.

Abstract

The invention relates to a bicycle labor-saving device and in particular relates to a bicycle labor-saving device which comprises a transmission rod, a Z-shaped connecting rod, a pedal or handle device. One end of the transmission rod is connected with the pedal or handle device, the other end of the transmission rod is connected with a first cross rod in the Z-shaped connecting rod through a flywheel structure, the Z-shaped connecting rod comprises a pair of parallel cross rods and a vertical rod fixedly connected between the two cross rods, the first cross rod is connected with the transmission rod through the flywheel structure, a second cross rod is used for rotatably connecting with a bicycle frame, and a keyboard is also fixedly connected to the connecting end of the vertical rod and the second cross rod of the Z-shaped connecting rod for driving a bicycle flywheel or driving the bicycle flywheel by a guide wheel. With the adoption of the bicycle labor-saving device, the length of a transmission force arm can be increased, so that the purpose of labor saving is achieved.

Description

technical field [0001] The invention belongs to the technical field of non-motor vehicles, namely bicycles, tricycles and other vehicles, and more specifically relates to a labor-saving device for bicycles. Background technique [0002] Due to the limitation of the pedaling position of the existing common bicycle, the length of the single-arm lever used to be connected with the pedal on the chain plate is relatively short, which is not too labor-saving. Chinese patent ZL200620158888.2 discloses a labor-saving transmission rod for bicycles. Because the connection between the transmission rod and the first crossbar in the "Z"-shaped connecting rod is a rotational connection, the length of the transmission arm cannot be increased, so labor-saving cannot be achieved. Effect. Contents of the invention [0003] In order to solve the above problems, the present invention provides a bicycle labor-saving device, which can increase the length of the transmission arm, thereby achiev...
