Embodiment Construction

[0160] Figure 1 to Figure 3 Shown is an embodiment of an automatic door lock shown with a lockout control mechanism housed in a lock housing 1 provided with a panel 2 on which is provided a locking bolt mechanism 500 protrudes and retracts into the deadbolt hole of the lock housing 1. The locking out control mechanism includes a fixed strip 510, a moving strip 520, a lock actuating part and a stopper. A deadbolt mechanism biasing member 501 is provided between the deadbolt mechanism 500 and the lock case 1, one end of the deadbolt mechanism biasing member 501 is fixed on the lock case 1, and the other end is fixed on the deadbolt mechanism 500 , a biasing force is applied to the lock tongue mechanism 500 to make the lock tongue mechanism 500 extend out of the lock housing 1 in a direction perpendicular to the panel 22 . One end of the fixed strip 510 is fixed on the bolt mechanism 500, and a side edge of the fixed strip 510 parallel to the extending direction of the bolt me...

Abstract

The invention provides an automatic door lock, comprising a lock shell having a dead bolt hole molded with dead lock hole; a lock assembly installed on the lock shell panel and the lock shell bottom panel corresponding to a molded lock installation hole; a bolt mechanism installed in the lock shell capable of moving along the direction perpendicular to the lock shell panel; a locking control mechanism for controlling the bolt in the bolt mechanism extruding from and retracting into the panel; and a bolt locking mechanism matched with the door handle operating mechanism. The automatic door lock implements engagement and disengagement of the stop member with a fixed stripe and a movable stripe by coupling of the fixed and the movable stripe, the stop member is capable of engaging with the fixed and the movable stripe at different positions, incomplete unlocking operation due to extrusion of a bolt partially retracted into the shell is prevented.

Description

technical field [0001] The present invention relates to an automatic door lock. Specifically, the automatic door lock of the present invention mainly manipulates or controls the opening and closing process of the lock bolt through mechanical transmission. Background technique [0002] Chinese patent document CN2849063Y discloses a kind of automatic door lock, and this automatic door lock comprises a lockout control mechanism that is installed in the lock housing and controls the timing of deadbolt protruding. The lock out control mechanism includes a lock trigger assembly and a lock piece, the lock piece is removably arranged on the lock tongue member, and has a A locking block that cooperates with the parts and a limit cam controlled by the lock trigger assembly, when the control force of the lock trigger assembly on the limit cam is withdrawn, the lock block and The fixing part on the lock housing engages and prevents the protruding movement of the lock bolt member; The ...
