ANTI-PICKING LOCK SET

      
Application Number 18899749

Abstract

An anti-picking lock set is provided and includes a lock sleeve, a lock core inserted in the lock sleeve, a plurality of elastic members accommodated in a plurality of upper slots of the lock sleeve, a plurality of lower pins accommodated in a plurality of lower slots of the lock core, and a plurality of upper pins disposed between the elastic members and the lower pins. When the lock set is unlocked by picking pins, a twisting force is first exerted on the lock core, and then the upper pins are pushed toward the upper slots. During the pushing process, since a ring groove of the upper pin moves to and is engaged with a side of a ring protrusion of the lock sleeve, an illusion of the upper pin being completely pushed into the upper slot is generated, which makes it difficult to complete the unlocking.

Abstract

An electronic door lock with up-pushed locking is provided and includes a housing, a fixed latch assembly assembled in the housing, a linkage member and a first driving member. The first driving member is linked with an outer handle located outside a door. When a user lifts the outer handle, the first driving member is pulled to drive the linkage member, so that the linkage member abuts against a protruding rod located at a rear end of the fixed latch assembly, thereby pushing the fixed latch assembly to actuate, so that a fixed latch head of the fixed latch assembly protrudes out of the housing and the electronic door lock is locked. Accordingly, the problem that the user must use a key to lock the electronic door lock when the user is outside the door can be solved.

Abstract

An electronic door lock is provided and includes a housing, a movable latch assembly, a telescopic rod, a driving member, an elastic member and a driving assembly. The telescopic rod is arranged in the movable latch assembly, and the elastic member is connected to the movable latch assembly and the driving assembly. The elastic member is driven by the driving assembly to drive the movable latch assembly, so that the telescopic rod located in the movable latch assembly can be controlled to retract or protrude from the movable latch assembly and the movable latch assembly is in a locked mode or an unlocked mode. In the unlocked mode, the driving member can push the telescopic rod to drive the movable latch assembly to move. Therefore, the problem that the driving assembly must accurately calculate the operating time can be solved and damage to the driving assembly can be prevented.

Abstract

A transmission structure includes: a turn button; a driven wheel including a wheel body and connecting parts having free ends or pushing blocks; and an actuating member including abutting parts corresponding to the free ends or the pushing blocks. When the driven wheel rotates, each of the free ends or each of the pushing blocks abuts against a corresponding one of the abutting parts. Also, the actuating member moves with a rotating shaft, and a latch connected to the rotating shaft displaces between a locked position and an unlocked position. When the driven wheel rotates, the latch does not displace and the actuating member cannot rotate. Also, each of the free ends or pushing blocks is still abutted by the corresponding one of the abutting parts and is curved elastically or deformed until the free end or the pushing block spans across the corresponding one of the abutting parts.

In a handle-returning device of a cylinder lock assembly, a support base has an inner annular flange and an axial spring-retaining lug. A rotation driver has an inner tubular wall extending into the inner annular flange of the support base, and a spring driving element. A torsion spring is disposed around the inner annular flange and between the support base and the rotation driver, and has a spring leg abutting the spring-retaining lug and the spring driving element. A rotary plate abuts the support base opposite to the rotation driver, and has an engaging part engaging a tongue projecting from the rotation driver. A reinforced structure is thus provided to oppose high torsional stresses produced upon rotation of a lever handle.

Abstract

A door lock assembly includes a transverse retaining plate disposed inside a spindle tube and having a stabilizing part and a retaining tongue projecting into a retention slot in a handle. A support structure is disposed within the handle oppositely of the retention slot and has a support part extending radially into the spindle tube. When the door lock assembly is in a locking state and when the retaining tongue in the retention slot is pressed externally, one of two diametrically opposite edges of a tailpiece of a key plug abuts against the support part, and the other one of the edges abuts against the stabilizing part of the retaining plate to restrict the retaining tongue from moving away from the retention slot, thereby preventing undesirable removal of the handle from the door lock assembly.
