Abstract

The invention relates to a vertical pipe folder, which comprises a locking ring, a vertical pipe, and a folding support. The vertical pipe comprises an upper guide element of locking ring; the folding support has a fixing element; the guide element has a positioning hole; the fixing element has a positioning groove; and the positioning hole and the positioning groove are through with sliding rod. The invention has easy installment, while loosening the locking ring, lifting the vertical pipe, its lower plane will leave the upper part of folding support, the device can be folded; if the upper part of folding support is sheathed inside the vertical pipe, the vertical pipe is locked. And the folding support is sheathed inside the pipe without rotating the folding base, the invention can improve safety.

Description

technical field [0001] The invention relates to the application field of folding bicycles, in particular to a standpipe folder suitable for manpower and electric bicycles. Background technique [0002] At present, the standpipe folders in the folding bicycle market are all connected by the folding seat to the upper and lower standpipes, and are locked and opened by the quick lock. The folding seat is the key part of the folder, but the folding seat constituting the standpipe folder is relatively difficult to process. , the process is complicated, and the safety performance of the folder is unstable. [0003] The Chinese utility model patent ZL200420071512.9 "Folder for Folding Bicycles" filed on July 9, 2004 includes a front connecting plate connected to the front main pipe, a rear connecting plate connected to the rear main pipe, and front and rear connecting plates. One end of the plates is hinged together through a shaft, and one end of the shaft is provided with a handl...
