Internal-locking wire-control folding system

Abstract

The invention discloses a bicycle component, and aims to provide a simple internal-locking wire-control folding system which can simultaneously control two internal-locking folders to realize the function of safe locking and unlocking. The internal-locking wire-control folding system comprises a lifting lever assembly, a deconcentrator and two folder assemblies, wherein the deconcentrator is connected with the lifting lever assembly through a first wire tube; the two folder assemblies are connected with the deconcentrator respectively through a second wire tube and a third wire tube; each folder assembly comprises a lower joint and an upper joint, and the lower joints and the upper joints of the two folder assemblies can respectively hinged together and cooperatively locked with each other; the side of the upper joint is provided with a locking pin; the inner side of the upper end of the locking pin is provided with an upper locking conical slope and a lower locking conical surface; and the lower joint is provided with a joint opening conical surface locking groove which cooperates with the locking block slope and the locking block conical surface. The invention breaks through the traditional control mode, can simultaneously control the functions of unlocking and locking of two folders, is different from the traditional control mode for folders, and does not need to install a handle on the folders, thereby enhancing the aesthetic property and practicality of the folders.

Description

technical field [0001] The invention relates to a bicycle component, in particular to an inner-locking wire-controlled folding system used on a folding bicycle. Background technique [0002] Because bicycles have many advantages such as low price and convenient walking, they soon become an indispensable means of transportation in daily life in China. With the continuous improvement of people's living standards, people's requirements for bicycles are also getting higher and higher. Because of its novel and compact structure, it is easy to carry and take up little space after being folded, and is more and more loved by people. At present, the known internal locking folder for folding bicycles uses the operating handle installed on the outside of the folder to control the locking part installed inside the folder to achieve the locking function. The operation process is: each folding bicycle has The frame and standpipe are connected by two folders, and each handle and safety de...

AI Technical Summary

Problems solved by technology

At present, the known internal locking folder for folding bicycles uses the operating handle installed on the outside of the folder to control the locking part installed inside the folder to achieve the locking function. The operation process is: each folding bicycle has The frame and standpipe are connected by two folders, and each handle and safety device attached to the folder on the frame and standpipe must be operated one by one to achieve the locking or opening effect. During the operation It needs complicated movements such as bending over and turning sideways to complete, and each folder needs to add an operating handle to operate the folder. There are many actions during the operation process, and it does not really achieve the simplicity and speed pursued by the folding bike. , a function for easy operation

Moreover, the traditional internal lock folder has a complex shape and too many protrusions, which will affect the overall appearance of the bicycle, which is simple and beautiful. The operating handle and exposed parts will also interfere with other bicycle parts during the use of the product. It will even cause harm to people during operation and riding
