Handle device capable of preventing unlocking from cat eye and door lock

Abstract

The invention discloses a handle device capable of preventing unlocking from a cat eye and a door lock. The handle device comprises a handle provided with a pressure sensor for detecting a pressing force, a handle linkage member connected to the handle and acting along with movement of the handle, and a clutch mechanism, wherein a clutch end of the clutch mechanism is in clutch limiting fit with the handle linkage member, and a drive controller of the clutch mechanism is connected to the pressure sensor. When the pressure sensor detects the pressing force on the handle, the drive controller receives a pressure signals transmitted by the pressure sensor, and controls the clutch mechanism to act, so that the clutch end and the handle linkage member are deviated from limiting fit, and the handle is allowed to perform an unlocking motion; and after the handle is reset to a locked position, the drive controller controls the clutch end to reset to a position in limiting fit with the handle linkage member. The handle device can perform an unlocking action only needing to be held in a hand; and after the hand releases, the action of the handle is automatically limited, so that the safety is improved, and meanwhile, unlocking is convenient and fast.

Description

Technical field [0001] The present invention relates to the technical field of locks, in particular to a handle device for preventing cat-eye unlocking. The invention also relates to a door lock including the handle device. Background technique [0002] In the door lock market, whether it is a smart door lock or an ordinary door lock, in order to prevent criminals from using tools to open the door lock from the door after passing through the peephole, the door lock’s rear panel is usually equipped with an anti-peephole unlocking structure. Increase the security level of the door lock. [0003] The existing peephole-proof unlocking structure is mainly a mechanical fool-proof button structure, and the mechanical fool-proof button structure usually has three forms: a button toggle type, a button pressing type, and a button rotation type. These mechanical fool-proof button structures have the following problems: When using, the user needs to lock the button of the anti-cat's eye unlo...

AI Technical Summary

Problems solved by technology

These mechanical fool-proof button structures have the following problems: when in use, the user needs to lock the button of the anti-peephole unlocking structure in the door, and the user will check whether the anti-peephole button is locked every time. If the button is locked, the anti-peephole unlocking structure cannot be activated; when opening the door lock from the inside, the user needs to unlock the button from the inside of the door before opening the door, which makes the action cumbersome and not convenient to use; when no one is inside the door, Because the button cannot be locked, the anti-peephole lock structure cannot be activated

[0004] In summary, how to solve the problem of inconvenient use and low safety of the anti-cat-eye structure has become a problem to be solved urgently by those skilled in the art
