Abstract

The invention discloses a locking device of a bicycle seat tube. The locking device is composed of a base, calipers and tooth grooves; the base and a frame beam are connected into a whole; the calipers are arranged on the base, and a calipers shaft of the calipers is fixed on the base; a tooth protruding inward is arranged on each jaw of the calipers, the tooth grooves are formed in the two sides of the seat tube of a bicycle, and each tooth groove is matched with the corresponding tooth; when the calipers are in a closed state, each tooth of the calipers is capable of being connected with the corresponding tooth groove into a whole in a meshed mode, thereby the seat tube is locked and cannot slide downward or swing leftward or rightward; when the bicycle seat height needs to be adjusted, a calipers handle is pinched by a hand so that the teeth can leave the tooth grooves of the seat tube, the seat tube is drawn and inserted in the vertical direction, when the required height is reached, the calipers handle is loosened, the teeth are made to be meshed with the tooth grooves once again, and a bicycle seat can be located.

Description

technical field [0001] A locking device for a 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; 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 locking device for bicycle seat tubes, so as to eliminate the above-mentioned defects; the device is composed of a base, a caliper and a tooth groove; the base is a tubular body that can be sleeved on the upper end of the vehicle frame The shape of the base is T-shaped; the width of the upper opening of the base is not less than 3 mm, so as to support the calipers set on it; the base and the frame beam are fixedly connected into one; [0004] Ther...
