Inside operating device for door lock

Abstract

The invention provides an inner side operation device for a door lock. The door lock is installed in a plunger latch device in a door. The inner side operation device is installed on the inner side face of the door, and comprises a first induction piece and an electric driving device electrically connected with the first induction piece; the inner side operation device further comprises a second induction piece installed in the plunger latch device; and after the first induction piece inducts pressure applied to the outer side of the inner side operation device, the electric driving device isdriven to run, so that a latch head can be moved to the latch unlocking position from the latch locking position, and when the plunger latch device is set in the locking or unlocking state, the secondinduction piece outputs one corresponding signal to a light emitting device of the inner side operation device to generate bright light, so that the locking or unlocking state of the plunger latch device can be indicated.

Description

technical field [0001] The invention relates to an inner operating device for a door lock, in particular to a device installed on the inner side of a door for operating a latch head of a latch device installed in the door to move between the latch position and the unlock position An inside operating device for a door lock. Background technique [0002] A commercially available door lock is often used on an escape door or an access door, and is generally called an escape door lock. This escape door lock usually includes an outer operating device installed on the outer side of the door, installed on the inner side of the door and An inside operating device of a different type from the outside operating device, the escape door lock further includes a latch device installed in the door and can be operated separately by the inside operating device or the outside operating device respectively, the latch device includes a A bolt head displaced between a latched position and an unl...

AI Technical Summary

Problems solved by technology

[0004] Since the escape door lock can be opened with the inner operating device regardless of whether it is set to the locked or unlocked state, so when the user is on the inside of the door, the escape door lock is set to the locked state and cannot be operated by operating the inside The operating device confirms whether the escape door lock is indeed set to the locked state, which makes it inconvenient to use

[0005] Furthermore, the mechanical structure of the inner operating device of this escape door lock is complicated, and the manufacturing cost is also relatively high.
