Abstract:
A lock assembly includes a fixing plate fixed to an inner side of a door. An inside rose liner is fixed to the fixing plate. A shaft is rotatably mounted in an axial hole of the fixing plate and coupled with a tail piece of an auxiliary lock body. An inside handle includes an inside spindle rotatably mounted in another axial hole of the fixing plate. A control mechanism includes a sliding plate slidably mounted in the inside rose liner, a driving wheel mounted on the inside spindle to turn therewith, and a driven wheel mounted on the shaft to turn therewith. Each of the driving wheel and the driven wheel includes at least one pressing section on an outer periphery thereof for pressing against an associated pressing portion of the sliding plate. The auxiliary lock is simultaneously unlatched when the inside handle is turned.
Abstract:
An unlocking device for the lever handle door lock includes an inner lever, an outer lever, an inner mounting plate, an outer mounting plate, a spindle, an inner actuating rod and an outer actuating rod. The inner mounting plate and the outer mounting plate mount the inner lever and the outer lever. Each of the inner lever and the outer lever has an assembling hole so that the inner lever and the outer lever are correspondingly connected to the inner actuating rod and the outer actuating rod for separately operating a latch bolt unit. The inner actuating rod has an end capable of disengaging from that of the outer actuating rod so as to avoid driving the inner actuating rod.
Abstract:
An electrical connector assembly including a first connector and a second connector to be mated with each other is provided. The first connector includes a first body, and at least one first terminal and multiple second terminals disposed therein. The second terminals are symmetrically arranged at opposite sides of the first terminal. The second connector includes a second body, at least one third terminal movably disposed in the second body, multiple fourth terminals disposed in the second body and symmetrically arranged at opposite sides of the third terminal, and a driving module electrically connected to at least one of the fourth terminals and structurally connected to the third terminal. In the mating process of the first and second connector, the second terminals and the fourth terminals are electrically connected firstly, to trigger the driving module to move the third terminal to be structurally and electrically connected to the first terminal.
