Locking device for snap ring bicycle seatpost

Abstract

The invention relates to a clamp ring type locking device of a bicycle seat tube. The clamp ring type locking device of the bicycle seat tube is composed of clamp rings, clamp grooves and bottom grooves. The clamp rings, the clamp grooves and the bottom grooves are matched with one another. Sections of the clamp grooves are formed at the sides of the bicycle seat tube symmetrically, and the clamp grooves are in a sunken inward shape. The elastic clamp rings are clamped to the clamp grooves. Handles and buttons are arranged on the clamp rings, pinching the buttons by a hand can enable the clamp rings to open outward and leave the clamp grooves, the bottom grooves are formed in the upper ends, corresponding to a bicycle tube, of the clamp rings, the clamp grooves entering the clamp grooves can exactly fall into the bottom grooves, and thereby the purpose of fixing the seat tube is achieved.

Description

technical field [0001] A locking device for a snap ring type bicycle seat tube belongs to the field of bicycle accessories. Background technique [0002] Many cities are now equipped with public bicycles to achieve the purpose of low-carbon travel; however, most of the existing devices use an omega-shaped clamp structure, and there is a possibility that the lock is not tight, and the seat slides down during riding. And the swing defect of left and right rotation, and after a period of use, the Ω-shaped clamp will scratch and damage the skin of the seat tube seriously, and the rust is very ugly, so it needs to be improved to overcome. SUMMARY OF THE INVENTION [0003] The purpose of this application is to provide a snap ring type bicycle seat tube locking device, so as to eliminate the above-mentioned defects; the device is composed of a snap ring, a snap groove and a bottom groove; symmetrically arranged on both sides of the bicycle seat tube A section of card slot (sever...
