The invention discloses a bicycle anti-theft device. The bicycle anti-theft device comprises a group of ratchet mechanisms which are arranged on center shafts of pedals of a bicycle frame and oppositeto pedal large fly wheels, each of the ratchet mechanisms comprises a ratchet, a ratchet seat, two ratchet paws, a lock body, a lock cylinder shifting block and a ratchet seat cover. Each ratchet seat is fixed to the bicycle frame and is of a hollow structure, the two ratchet paws are symmetrically arranged in each ratchet seat, one ends of the ratchet paws are connected with each ratchet seat toswing freely, and the other ends of the ratchet paws are provided with more than one ratchet tooth and a reset spring to be connected to the interior of each ratchet seat. Each ratchet seat cover fixedly covers the corresponding ratchet seat, each lock body is arranged on the corresponding ratchet seat cover, and each lock cylinder shifting block is arranged between the two ratchet paws. Each ratchet is fixedly connected to the left end of the center shaft of the corresponding pedal in a sleeving mode and cannot move. The ratchet seats are coaxially arranged on the peripheries of the ratchets. The bicycle anti-theft device and a bicycle are of an integrated structure, the whole bicycle anti-theft device can be hidden, extra space is not occupied, and the bicycle anti-theft device can be used with an existing externally-arranged lockset in a matched mode to achieve a better anti-theft effect.
Description
technical field [0001] The invention relates to the technical field of anti-theft bicycles, in particular to an anti-theft device for bicycles. Background technique [0002] The bicycle has no noise, no pollution, light weight, simple structure, high quality and low price, convenient use and maintenance, and can be used as a tool for walking and carrying goods, and can be used for physical exercise. my country is a country with a large number of bicycles, and the incident of stealing bicycles occurs from time to time, so bicycle theft prevention has always been a very big problem. At present, the vast majority of bicycles use external lock devices such as chains and U-shaped locks to prevent theft. Most of these locks belong to the external type, which are very easy to be opened or damaged by thieves, and the anti-theft performance is not strong. Contents of the invention [0003] In order to solve the above-mentioned problems in the prior art, the present invention adds...
