Embodiment Construction

[0015] The present invention will be further elaborated below in conjunction with accompanying drawing:

[0016] Such as Figure 1 to Figure 3 The lifting device shown includes a housing 1, which is used to support and position each component on the one hand, and to protect each component from being oxidized too quickly when exposed to the air. , to extend the service life of the whole device, the side wall of the housing 1 is provided with a rack 7 that slides up and down, the rack 7 and the housing 1 are connected through a dovetail groove, and the rack and the housing are connected by The combination of the dovetail groove ensures the smoothness of the sliding between the two, prevents the jamming state during sliding, and improves the stability of the entire lifting device. One end of the rack is equipped with a lifting rope, which is connected with manual force. device connection, the other end of the rack 7 is provided with an elastic reset device 8 connected to the hou...

Abstract

The invention belongs to the field of accessories of bicycles and particularly relates to a lifting device for braking a bicycle through a relatively small clamping force. The lifting device is characterized by comprising a shell, wherein a rack which slides up and down is arranged on the sidewall of the shell; a pulling rope is arranged at one end of the rack; the lifting device further comprises a gear transmission device connected to the rack; the gear transmission device comprises a big gear connected to the rack and a small gear engaged with the big gear; both the big gear and the small gear are connected to the shell through connecting shafts; the connecting shaft of the small gear is connected to a connecting block through a connecting cable; and the connecting block is provided with a pair of connecting rope. Through a gear transmission mechanism, the lifting device, disclosed by the invention, has the advantages of obtaining a relatively big braking stroke for a running bicycle by manually applying a relatively small stroke, overcoming the disadvantage that the conventional synchronous braking device needs to apply a relatively big stroke manually, guaranteeing reliability of synchronous braking and being convenient to popularize synchronous parking devices.

Description

technical field [0001] The invention belongs to the field of bicycle accessories, in particular to a lifting device for braking a bicycle through less clamping force. Background technique [0002] my country is a big country of bicycles. Bicycles are a common means of transportation for people to travel short distances in daily life. Some bicycle companies in my country have also improved various parts of bicycles. First, there is a lifting device that can brake the front and rear wheels at the same time. , it drives a connecting block to slide through the manual brake, and the connecting block drives the front and rear brake wires to brake. At the same time, the front wheel brake also uses a spring to realize a delayed braking function, but this will increase the manual braking stroke. , People often need a lot of power to brake the car, so the present invention makes improvements to the deficiencies in the prior art. Contents of the invention [0003] Aiming at the defici...
