Further, the top of the lower frame is provided with a mounting hole, and the lower end of the support pipe is inserted into the mounting hole of the lower frame and connected by screws.

Further, the upper frame is provided with slots on both sides of the installation hole, and the slots communicate with the installation hole to increase the installation space of the support tube.

Further, the upper frame is provided with perforations on both sides of the slot, and after the support tube passes through the installation hole, screws are passed through the perforations of the upper frame to securely fix the support tube on the upper frame.

Further, the handle is installed on the free end of the upper frame through a quick release structure.

The beneficial effect of the utility model is that the joints of the parts are connected by screws and the quick release structure, and after the screws are removed and the quick release structure is rotated, the bicycle is divided into a drive module, a support tube, an upper frame, a seat cushion module and handle, effectively reducing packaging and shipping costs.

Detailed ways

In order to make the technical solution of the utility model can be expressed more clearly, the utility model will be further described below in conjunction with the accompanying drawings.

Please refer to Figures 1 to 3, a bicycle with a convenient disassembly structure of the present invention includes a drive module 10, a support tube 20 connected to the drive module 10, respectively connected to the drive module 10 and the support The upper frame 30 of the tube 20 , the cushion module 40 installed on the support tube 20 and the upper frame 30 , and the handle 50 installed at the free end of the upper frame 30 .

The driving module 10 includes a lower frame 11, a driving wheel 13 and two driven wheels 14 respectively connected to two ends of the lower frame 11, a pedal 15 installed in the middle of the lower frame 11, and a pedal 15 installed inside the lower frame 11 to connect the feet. Step 15 and the connecting device of drive wheel 13. The lower frame 11 is designed in an arc shape, and is formed by combining left and right symmetrical shells. Two mounting plates 110 extend from one end of the lower frame 11 close to the driving wheel 13 , and each mounting plate 110 is correspondingly provided with two spaced through holes 112 . A mounting hole 116 is defined at a top middle portion of the lower frame 11 for receiving a lower end of the support tube 20 . The lower frame 11 defines two through holes 117 corresponding to the lower side of the mounting hole 116 . Both the mounting holes 116 and the through holes 117 are disposed above the corresponding mounting positions of the pedals 15 .

The support tube 20 is arranged in a hollow straight tube shape. The lower end of the support tube 20 defines a through hole 27 corresponding to the installation hole 116 of the lower frame 11 . The top of the support tube 20 is provided with a perforation 28 and an axis opening slot 29 , and the opening slot 29 is used to facilitate the installation and insertion of the seat cushion module 40 .

The upper frame 30 is arranged in an S shape, and a perforation 31 is formed at the bottom thereof to correspond to the perforation 112 of the lower frame 11 . A mounting hole 34 and slots 36 defined on both sides of the mounting hole 34 are defined in the middle of the upper frame 30 . The slot 36 communicates with the through hole 34 so that there is a certain reserved space when inserting the support tube 20 . The upper frame 30 is provided with a plurality of perforations 38 on the sides of the through hole 34 and the slot 36 , and the support tube 20 and the cushion module 40 are fixed by screws 80 .

The cushion module 40 includes a cushion 41 and a positioning tube 42 fixed to the bottom of the cushion 41 . The outer diameter of the positioning tube 42 is slightly smaller than the inner diameter of the support tube 20 to facilitate installation and embedding in the support tube 20 .

The handle 50 is fixed on the front end of the upper frame 30 through a quick release structure 60 . The handle 50 is arranged in a U-shaped bend, and its middle part is detachably fixed on the quick release structure 60 .
