Abstract

The invention provides a manufacturing method of a locking device of a bicycle seat tube. The locking device is composed of a base, a caliper and tooth grooves; the base and a bicycle frame beam are connected into a whole, the caliper is mounted on the base, the upper portion of a caliper opening of the caliper is connected with a section of teeth inwards extending out; the two sides of the bicycle seat tube are connected with the tooth grooves, and the tooth grooves are matched with the teeth; and when the caliper is in a closed state, the teeth of the caliper can be connection with the toothgrooves into a whole in an engaged mode, and thus the seat tube is locked and cannot slide downwards and swing leftwards and rightwards. During using, a caliper handle is pinched by a hand, so that the teeth leaves the tooth grooves of the seat tube, the seat tube is drawn and inserted up and down, after the seat tube reaches the required height, the caliper handle is loosened, and the teeth andthe tooth grooves are re-engaged so that a bicycle seat can be positioned.

Description

technical field [0001] The invention discloses a method for manufacturing a locking device of a bicycle seat tube, which 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; The swing defect of left and right rotation, and after using for a period of time, the U-shaped clip seriously damages the skin of the seat tube, and the rust is very ugly, so it needs to be improved and overcome. Contents of the invention [0003] The purpose of this application is to provide a method of manufacturing a locking device for a bicycle seat tube, so as to eliminate the above-mentioned defects; the device consists of a base, a caliper and a tooth groove; the shape of the base is a T-shape with a large top and a small bottom; Support the calipers set on it; the base is made of a section of steel pipe that can be set on the upper end of the frame beam (the place where the U-s...
