Bicycle automatic lock

Abstract

The invention discloses a mechanical device which can automatically lock a bicycle through a movement of kicking down a stand. The mechanism is formed by the assembling of parts and components including a blocking block a (5), a blocking block b (6), a sliding block (4), a bicycle locking rod (7), a guide rail (1) and the like in a cuboid metal housing, and the parts and components are mutually restrained and fitted; a steel wire (12) is additionally arranged at a bicycle lock movement part, and one end of the steel wire (12) is connected with the sliding block (4), and the other end of the steel wire (12) is connected with the stand. When a person kicks the stand down, the steel wire fixed to the stand pulls the sliding block to move in the guide rail, and drives the composite unit of the bicycle locking rod (7) to rotate for 90 degrees and stand up to block wheel spokes, so that the purpose of locking is achieved, and adding a lock for anti-theft is become more convenient and swift; and when unlocking the bicycle, a key is twisted, and the stand is retracted, the bicycle locking rod composite unit is retracted under the effect of return springs, and the bicycle is unlocked.
