Door lock convenient for back locking and inward opening
The door lock comprises a lock body, a spring bolt and a pull-back mechanism, the spring bolt can pop out to be matched with a lock catch box on a door frame, the pull-back mechanism comprises two internally and externally arranged handle shifting forks, and the two internally and externally arranged handle shifting forks are connected with two internally and externally arranged handles respectively. The lock body is provided with a lock cylinder counter locking mechanism, a handle pressing unlocking mechanism and a handle lifting counter locking mechanism. The number of the lock tongues is small, noise is low, resistance is small when the inner handle and the lock cylinder are used for unlocking, a mechanism is not prone to damage, and the service life of a product is long; the spring bolt can be driven to perform counter locking by lifting and rotating the handle without operating the lock cylinder by a key, so that the operation is relatively convenient; the lock tongue can be driven to retract by pressing the inner handle downwards, the rotating angle needed by the inner handle is small during unlocking, and operation is more sensitive.
本发明公开了一种方便反锁和内开的门锁，包括锁体、锁舌和拉回机构，锁舌可以弹出与门框上的锁扣盒配合，拉回机构包括两个内外设置的执手拨叉，两个内外的执手拨叉分别连接两个内外的执手，所述锁体上设有锁芯反锁机构、执手下压解锁机构和执手上提反锁机构。本发明的锁舌数量少，噪音小，用内执手和锁芯进行解锁时阻力比较小，机构不容易损坏，产品使用寿命长；锁舌通过执手上提转动即可驱动进行反锁，无需钥匙操纵锁芯，操作比较便捷；下压内执手就能在带动锁舌缩回，解锁时内执手所需的转动角度小，操作更加灵敏。
