The invention discloses a lock with a four-way bolt, the lock comprises a main lock tongue, a rear lock tongue, an upper lock tongue and a lower lock tongue, and a lock core, and a drive gear is coaxially connected with the door handle on the lock body The lock body is horizontally mounted with a control gear perpendicular to the main lock tongue. The main lock tongue is provided with strip teeth that mesh with the drive gear and strip teeth that mesh with the control gear, the rear lock tongue, the upper lock tongue and A bar-shaped tooth that meshes with the control gear is disposed on the lower locking tongue. The invention realizes the use of the gear transmission form instead of the tension spring transmission in the traditional lock structure by providing the driving gear and the control gear in the lock body and the corresponding strip teeth on the four-way bolt, which not only ensures the effective function of the bolt. The transmission also breaks through the length limit of the bolt caused by the tension spring structure, which is beneficial to improve the safety performance of the whole lock. At the same time, the mechanical performance of the gear transmission structure is better than that of the tension spring transmission structure, which greatly improves the service life of the lock.
