Detailed Description

The construction and principles of the present invention will be readily apparent to those skilled in the art from the following description taken in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.

Referring to fig. 1, 3 and 4, the present invention is a modular bicycle frame with a detachable module, comprising a handling module, a support module, a power module, a cross member assembly and disassembly assembly, and a center tube assembly.

The middle pipe disassembly and assembly component consists of a seat vertical pipe, a decoration piece, an upper end quick disassembly, a middle pipe front section, a middle pipe rear section and a lower end quick disassembly. The upper end of the support module is quickly disassembled and fixed on the front section of the middle pipe by using screws, the front section of the middle pipe is a semicircular special-shaped section bar, and the support module is connected with the support module by adopting a welding mode; the lower end is quickly disassembled and fixed on the rear section of the middle pipe by using a screw, the rear section of the middle pipe is the same as the front section of the middle pipe and is a semicircular special-shaped section bar, and the lower end is connected with the power module in a welding mode; the front section of the middle pipe and the rear section of the middle pipe are assembled up and down; after the decorating part is sleeved into the seat stand pipe, the seat stand pipe is inserted into a round hole in the middle of the front section of the middle pipe and the rear section of the middle pipe, so that the whole mechanism is in a semi-locking state, and finally, after the height of the seat stand pipe is adjusted, the assembly can be completed by quickly disassembling and locking the upper end and the lower end.

Referring to fig. 2, the cross beam assembly and disassembly assembly is composed of a knob, a screw, a pressing plate, a spring, a front module, a jackscrew and a rear module. The knob is formed by injection molding of plastic materials, has smooth appearance and no edges and corners, and can be internally provided with internal threads for assembling the external threads of the end A of the screw rod; the B end of the screw rod passes through the middle circular hole of the pressing plate after the screw rod is assembled with the knob, the spring is sleeved on the B end of the screw rod, and finally the B end of the screw rod is installed in the circular hole of the front module, the front module is connected with the control module in a welding mode, and the groove at the top end of the screw rod is propped against the groove through the jackscrew, so that the screw rod is fixed in the front module. And finally, assembling and matching the front module and the rear module, rotating the knob to discharge the gap so as to completely close the gap, and connecting the rear module with the support module in a welding mode.
