Abstract

The invention relates to a semicircular shaft locking-type foldable saddle pipe, which comprises an upper foldable piece, a lower foldable piece, a counter-locking bolt, a semicircular locking shaft, a safety pin, a torsion spring, an upper pipe fitting and a lower pipe fitting. The upper foldable piece is a component with one side which is hook-shaped and the other side which is provided with rings at two ends. The lower foldable piece is a groove-shaped component. The two ends of the lower foldable piece are provided with two pairs of through circular holes. The middle part of the lower foldable piece is provided with a pair of through rectangular holes. The ring holes of the torsion spring are put in the two rings of the upper foldable piece, the cylinder of the counter-locking bolt penetrates through one pair of through circular holes of the lower foldable piece and then penetrates through the ring hole of the upper foldable piece and the ring holes of the torsion spring, the bolt and the cylinder are counter-screwed for locking, the semicircular locking shaft is installed into the other pair of through circular holes of the lower foldable piece, the semicircular locking shaft is turned to lock the hook-shaped side of the upper component, the safety pin is installed into the pair of the through rectangular holes of the lower foldable piece, the spring is assembled, the safety pin is matched with the locking handle of the semicircular locking shaft, the semicircular locking shaft can be positioned, the upper pipe fitting is connected with the upper foldable piece and the lower pipe fitting is connected with the lower foldable piece.

Description

Technical field [0001] The invention relates to a folding saddle tube, in particular to a semicircular shaft locking type folding saddle tube. technical background [0002] Although there are several types of folding saddle tubes currently equipped on bicycle saddles, there is no way to find a simple and effective semicircular shaft locking folding saddle tube. Summary of the invention [0003] The purpose of the present invention is to provide a semicircular shaft locking type folding saddle with a simple and effective structure and quick and convenient use. The purpose of the present invention is achieved in this way; the semicircular shaft locking folding saddle tube includes an upper folding leaf, a lower folding leaf, a pair of locking bolts, a semicircular locking shaft, a safety pin, a torsion spring, an upper tube and a lower tube, which are characterized by : The upper folding leaf is a part with a shape on one side and a ring on the other side and a cut-off shape in t...
