FIG. 1 is a structural schematic diagram of a door lock for monitoring the door status proposed by the present invention.

detailed description

With reference to Fig. 1, a kind of door lock structure that the present invention is used for monitoring the door state function, comprises signal transmitter 1, and signal transmitter 1 is connected in series with button switch K1, the first touch switch K2 that disconnects under normal state and Normally closed magnetic switch K3. When the button switch K1 , the first touch switch K2 and the magnetic switch K3 are all closed, the signal transmitter 1 sends a signal. In this embodiment, the signal transmitter is wirelessly connected to a preset communication terminal. The communication terminal can be a mobile phone of a family member or the like. In this way, when the signal transmitter emits a signal, the family members can know in time to judge the state of the door lock.

In this embodiment, the button of the button switch K1 is installed outside the door frame. When the button is pressed, the button switch K1 is closed. In this embodiment, the button switch K1 is used as a sign for opening the door lock monitoring.

An elastic contact is installed in the deadbolt slot installed on the door frame, and the installation position of the first touch switch K2 corresponds to the elastic contact. When the deadbolt is inserted into the deadbolt slot, the elastic contact presses the first touch switch K2 to close. Normally, only when the door is closed and locked, the deadbolt will be inserted into the deadbolt slot, that is, the first touch switch K2 is closed only when the door is closed and locked.

An electromagnet 2 is installed on the lock body. When the door is closed, the position of the electromagnet 2 corresponds to the magnetic control switch K3. When the electromagnet 2 is powered on, the magnetic control switch K3 is disconnected. The electromagnet 2 is connected in series with a second touch switch K4, the lock cylinder is provided with a contact block 3, and the second touch switch K4 is installed on the rotation track of the contact block 3. The contact block 3 rotates with the rotation of the lock cylinder. When the lock cylinder 4 rotates to the position where the lock tongue protrudes, the contact block 3 abuts against the second touch switch K4, so that the second touch switch K4 is pushed out when the lock tongue protrudes. Closed in the state, the electromagnet 2 is energized. That is, in the state where the door is closed and the dead bolt is extended, the magnetic control switch K3 is turned off.

In this way, during the specific implementation of this embodiment, when the user presses the button switch when going out, the door is closed at this time, the first touch switch K2 is closed, the magnetic control switch K3 is disconnected, and the signal transmitter does not work; when the magnetic control switch is closed, Then the current branch where the signal transmitter 1 is located is turned on, so that the signal transmitter works, transmits a signal, and sends the abnormal state of the door lock to the preset object.

When the signal transmitter is working, both the first touch switch K2 and the magnetic control switch K3 are closed, and the first touch switch K2 is closed, indicating that the deadbolt is still in the retractable state. When the magnetic control switch is closed, it means that the electromagnet is powered off, that is, the second touch switch K4 is disconnected, and the lock cylinder does not rotate; or, the door is not closed correctly, and the positions of the electromagnet 2 and the magnetic control switch K3 are not corresponding. Therefore, through the cooperation of the first touch switch K2 and the magnetic control switch K3, the signal transmitter can effectively monitor the status of the door and the door lock, and timely alarm for abnormal status, thereby preventing the risk of theft.

In this embodiment, the communication terminal is a mobile phone, and the signal transmitter is connected with one or more communication terminals, so that multiple family members can monitor the door lock.

The above is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto, any person familiar with the technical field within the technical scope disclosed in the present invention, according to the technical solution of the present invention Any equivalent replacement or change of the inventive concepts thereof shall fall within the protection scope of the present invention.
