Referring to Fig. 4, a kind of oblique tongue driving square tongue ejection mechanism provided by the present invention includes a square tongue hook-shaped lever 41 installed on the bottom shell of the lock body through a pivot 42, and a square tongue hook-shaped lever 41 arranged on the square tongue assembly. The hooked cylinder 29 and the protruding post 17 arranged on the latch tongue assembly, wherein the cylinder 29 is arranged on the square tongue plate 24, the protruding post 17 is arranged on one side of the latch rod 12, and the pivot 42 is installed with Torsion spring 43, torsion spring 43 can make square tongue hook shape lever 41 reset. When the square tongue of the mortise lock is retracted, the square tongue hook-shaped lever is hooked on the cylinder, so that the square tongue assembly cannot be ejected and locked; when the oblique tongue assembly moves, the protruding post can press the square tongue hook-shaped lever And make it rotate, thereby make the square tongue hook-shaped lever disengage from the cylinder on the square tongue assembly, at this moment the square tongue assembly can eject outward automatically.

The working principle of the present invention is as follows: when the mortise lock is in the normal open state, the protrusion presses against one side of the square tongue plate, and at the same time, the square tongue hook-shaped lever is hooked on the cylinder of the square tongue assembly. When the button is pressed, the button drives the push rod to move, and at the same time the push rod drives the anti-bullet lever which is movably connected with it to rotate, so that the bump moves away from one side of the square tongue plate, so as to release the restriction of the bump on the other tongue assembly. The lever is still hooked on the cylinder of the square tongue assembly, so the square tongue assembly cannot be automatically ejected outward at this time; when the door is closed, the oblique tongue assembly retracts inward under the action of the lock plate on the door frame. The protruding post on the middle latch rod presses the square tongue hook lever and makes it rotate, so that the square tongue hook lever is disengaged from the cylinder on the square tongue assembly. At this time, the square tongue assembly is under the action of the torsion spring It pops up automatically to achieve the purpose of automatic locking. At the same time, the square tongue lever rotates under the drive of the square tongue assembly, so that the square tongue lever is separated from the clutch lever. The clutch lever is engaged with the thumb wrench lever under the action of the torsion spring. At this time The thumb wrench lever cannot be rotated by the effect of the clutch lever, so the lock cannot be opened by the thumb wrench lever.

When the key is used to unlock the lock (purely mechanical function), the key drives the dial of the lock cylinder to rotate, the dial of the lock cylinder drives the dial lever to rotate, and the pin shaft on the dial rod drives the tongue plate to move into the bottom shell of the lock body. The square tongue assembly is opened, and the inward movement of the square tongue plate rotates the square tongue lever. The square tongue lever engages with the clutch lever and pushes the clutch lever, so that the clutch lever is separated from the thumb wrench lever. At this time, the thumb wrench lever can rotate. Pull the thumb wrench installed on the upper side of the door handle, the thumb wrench presses the thumb wrench lever, and the thumb wrench lever rotates, thereby driving the latch bolt assembly to retract inwardly, so as to realize the purpose of opening the latch bolt assembly.

When the lock is unlocked electronically, after the correct identification code is input, the electronic clutch assembly will act, and the clutch assembly will drive the clutch lever to rotate, so that the clutch lever is separated from the thumb wrench lever. At this time, the thumb wrench lever can rotate. The thumb wrench on the side, the thumb wrench presses the thumb wrench lever, and the thumb wrench lever rotates, thereby driving the oblique tongue assembly to retract inwardly, and at the same time, the oblique tongue presses the square tongue lever, so that the square tongue lever drives the square tongue assembly to retract, thereby The purpose of retracting the oblique tongue and the square tongue together is realized.
