Single-tongue double-position locking door lock
The invention discloses a single-tongue double-position locking door lock which comprises a transmission plate, a shifting piece, a trigger and a spring bolt. The transmission plate is arranged on the transmission plate slide way to slide left and right, and the convex part of the transmission plate corresponds to the first locking arc section or the second locking arc section of the trigger; the trigger is rotationally connected to the trigger rotating shaft; the shifting piece is rotationally arranged on the torsional spring shaft, the first shifting fork corresponds to the groove, and the second shifting fork is arranged on the left side of the push block. The door lock has the advantages that the door lock can be pushed by the frame lock plate to directly and automatically enter a fully-locked state, so that the door lock is prevented from being pried. The handle is used for opening the door to automatically enter a semi-locking state, and use is convenient.
本发明公开一种单舌双位锁紧门锁，包括传动板、拨片、触发器和锁舌；传动板设置在传动板滑道上左右滑动，传动板的凸起部与触发器的第一锁止弧段或第二锁止弧段对应；触发器转接于触发器旋转轴上；拨片旋转设置在扭簧轴上，第一拨叉与凹槽对应，第二拨叉设置在推块的左侧。本发明的优点是：能够利用框锁片的推动，直接将门锁自动进入全锁状态，防止被撬。而利用把手开门自动进入半锁状态，方便使用。
