Summary:The utility model relates to a lock for bicycles, comprising a lock bridge, a lock bolt, a lock core, a front sleeve, a back sleeve and a lock head which is fixed in the front sleeve. One end of the lock bridge is hinged with a pin which is fixedly connected with the front sleeve. The mandrel of the lock core is connected with the lock bolt by a connecting shaft. The lock core is provided with a guide pin, and the lock head is provided with a guide shaft matched with the guide pin. The lock head is provided with a radial groove of a built-in hollow positioning nail, and a spring is built in the hollow positioning nail. The connecting shaft is provided with a guide groove matched with the hollow positioning nail. A main spring is built in a cavity between the lock head and the connecting shaft. The lock bolt and the lock bridge of the lock for bicycles are conjoined structures; thus the operation is convenient, and the lock is not easy to lose. With the lock core outside the lock bolt, the manufacturing procedures are few.
