Locking control mechanism of automatic door lock

Abstract

The invention relates to a locking control mechanism of an automatic door lock. The locking control mechanism comprises a lock tongue, a trigger component arranged in an accommodation space (2) in a lock case or the lock tongue (2) and a locking component which is acted between the lock case and the lock tongue component and used for locking, wherein the trigger component comprises a touch rod (3) and a touch rod bias mechanism used for applying bias pressure to the touch rod (3); one end of the touch rod (3) is protruded out of a front panel of the lock case to form an actuating head (5), and the other end of the touch rod (3) is a trigger part (8); the actuating head (5) is moved to an effective trigger position or an invalid trigger position under the acting force on a door frame, which is opposite to a door opening direction or a door closing direction, so as to ensure that the locking to the lock tongue component of the locking component is relieved, and the lock tongue is automatically popped up to lock the door or keep a locking state to the lock tongue component.

Description

technical field [0001] The invention relates to a locking out control mechanism of an automatic door lock, in particular to an improvement on a touch lever type locking out control mechanism. Background technique [0002] At present, the unlocking action of the anti-theft lock in the prior art is usually achieved by rotating the key or manually rotating the lock handle to make the deadbolt stretch out. The door can only be closed after the tongue is retracted, and the key is also required to lock the door during the closing process, and the locking action cannot be automatically realized. This kind of anti-theft lock cannot automatically extend the lock tongue, so when the user forgets to turn the key or When the lock handle is used, the door using this lock loses the anti-theft effect. In addition, even if the key or the lock handle is not forgotten, the time for locking the door will be prolonged due to the need to rotate the key or the lock handle. [0003] In order to s...

Problems solved by technology

[0006] In order to solve the problem of mechanical automatic locks in the prior art, when the lock-out control mechanism encounters the door frame after the lock is unlocked, the deadbolt member will automatically pop up, and a key is required to retract the deadbolt member before closing the door, resulting in To solve the problem of inconvenient door closing, the present invention provides an automatic door lock in which the deadbolt member does not pop out automatically after the door is opened, and the deadbolt member can automatically extend out to lock the door after the door is closed. exit control agency
