Anti-locking method of a door lock

Abstract

The invention discloses a back locking method of a door lock. A first sensor is arranged in a lock body of the door lock and is used for detecting stretching or contracting motion of a locking component in the door lock and also used for generating a first feedback signal, a second sensor is arranged in the lock body of the door lock and is used for detecting rotating motion of a handle outside a door and generating a second feedback signal; a control module receives the first feedback signal and the second feedback signal; when a handle in the door is rotated to drive a main transmission mechanism to drive the locking component to stretch out, the first feedback signal is sent to the control module by the first sensor, and it is affirmed by the control module that the motion is back locking motion; afterwards, when the locking component is driven by the handle outside the door to rotate in the contracting direction, the first feedback signal is sent to the control module by the first sensor, the control module controls a clutch to be in disengagement state, the locking component is static at the moment, and it is affirmed by the control module that the motion is motion preventing back locking releasing. By means of the back locking method, back locking and back locking releasing can be easily, quickly and conveniently achieved.

Description

technical field [0001] The invention relates to a control method of a door lock, in particular to an anti-locking method of a door lock. Background technique [0002] In order to improve its ease of use and safety, door locks generally use smart locks. In daily use, the door is generally locked or unlocked by turning the handle. Locking and unlocking is achieved by turning the inside handle and outside handle. accomplish. Turning the inner handle of the door can drive the main bolt to expand and contract through the main transmission mechanism under any conditions. The inner handle of the door is directly connected with the main transmission mechanism, while the outer handle of the door is connected with the main transmission mechanism through a clutch. The handle can drive the main dead bolt to expand and contract. When the clutch is opened, turning the handle outside the door will idle in the clutch, and the main dead bolt will not move. Among them, the clutch closing me...

Problems solved by technology

[0005] Therefore, the user in the door is to perform anti-locking again safely and securely after locking, at first need to turn the handle in the door to drive the main bolt to lock, and then turn the knob to drive the safety bolt to lock, which is extremely inconvenient, and the user often Forget to turn the knob and cause the embarrassment of being disturbed by outsiders breaking into the room after it is not locked

When the user in the door needs to unlock the back lock, he needs to operate the above actions in reverse. It can be seen that the existing door locks are still relatively easy to use. Assembly rate
