Latch bolt mechanism and door lock with same
The invention discloses a latch bolt mechanism and a door lock with the latch bolt mechanism. The latch bolt mechanism comprises a mounting frame and a latch bolt, the latch bolt assembly comprises a first latch bolt and a second latch bolt which can be pivoted on the mounting frame in a manner of rotating between a locking position and an unlocking position around an axis extending parallel to the side edge of the fan body; the limiting assembly is arranged between the mounting frame and the latch bolt assembly, and a first limiting state that the first latch bolt is released and the second latch bolt is locked or a second limiting state that the first latch bolt is locked and the second latch bolt is released can be achieved through adjustment; the acting end of the latch bolt in the release state can rotate under the action of a door frame lock hole wall; the acting end of the latch bolt in the locking state is locked at the locking position, and the acting end of the latch bolt and the lock hole wall on the door opening side of the door frame are in a self-locking relation. When reversing is needed, the limiting assembly is adjusted to be in the first limiting state or the second limiting state, the latch bolt mechanism does not need to be rotated by 180 degrees in the lock body, it is avoided that a large hollow hole is formed in the lock body, and the leakproofness and strength of the lock body can be improved.
本发明公开了一种斜舌机构及具有其的门锁，斜舌机构包括：安装架；斜舌组件包括可绕平行于扇体侧缘延伸的轴线在上锁位置与解锁位置之间转动地枢接在安装架上的第一斜舌和第二斜舌；限位组件，设置在安装架与斜舌组件之间，通过调节可达到释放第一斜舌并锁定第二斜舌的第一限位状态或锁定第一斜舌并释放第二斜舌的第二限位状态；处于释放状态下的斜舌其作用端可在门框锁孔壁的作用下转动；处于锁定状态下的斜舌的作用端被锁定在上锁位置，其与门框上开门侧的锁孔壁之间为自锁关系。本发明在需要换向时将限位组件调整到第一限位状态或第二限位状态，无需将斜舌机构在锁体内旋转180°，避免在锁体内开设较大镂空孔，可提高锁体的密闭性和强度。
