[0002] At present, for locks with three-way or four-way deadbolts, the opening and closing of the lockset, that is, the displacement of the deadbolt, is mainly achieved by using a tension spring to drive. The lockset with this kind of tension spring structure has the following disadvantages due to its structural characteristics: 1. 1. The transmission structure is relatively complex, its operation stability is poor, it is easy to be damaged, and its service life is short; 2. It is difficult to realize automatic locking with multiple lock tongues, which brings inconvenience to people's use; 3. The transmission principle of the extension spring structure determines The maximum stroke of the bolt is small, which is not conducive to improving the safety performance of the lock

The invention discloses a lock with a four-way bolt. The lock comprises a main bolt, a back bolt, an upper bolt, a lower bolt and a lock core, wherein a drive gear is coaxially connected with a lock body and a door handle; a control gear which is perpendicular to the main bolt is horizontally installed on the lock body; a strip gear which is meshed with the drive gear and a strip gear which is meshed with the control gear are arranged on the main bolt; and strip gears which are meshed with the control gear are arranged on the back bolt, the upper bolt and the lower bolt. By mounting the drive gear and the control gear in the lock body and mounting the corresponding strip gears on the four-way bolt, the invention realizes the aim that a gear drive way replaces tension spring drive in the traditional lock structure, thereby not only ensuring the effective drive of the bolt, but also breaking through the bolt length limit caused by the tension spring structure and being beneficial to improving the safety performance of the whole lock; meanwhile, the mechanical performance of the gear drive structure is better than that of a tension spring drive structure, therefore, the service life of the lock is greatly improved.
Description
technical field [0001] The invention relates to a lock, in particular to a lock with a four-way deadbolt. Background technique [0002] At present, for locks with three-way or four-way deadbolts, the opening and closing of the lockset, that is, the displacement of the deadbolt, is mainly achieved by using a tension spring to drive. The lockset with this kind of tension spring structure has the following disadvantages due to its structural characteristics: 1. 1. The transmission structure is relatively complex, its operation stability is poor, it is easy to be damaged, and its service life is short; 2. It is difficult to realize automatic locking with multiple lock tongues, which brings inconvenience to people's use; 3. The transmission principle of the extension spring structure determines The maximum stroke of the dead bolt is small, which is unfavorable for improving the safety performance of the lockset. Contents of the invention [0003] The technical problem to be so...
