Abstract

In the door latch structure that the utility model discloses a kind of for monitoring door state function, when signal projector works, the first touch switch and magnetic switch are closed, and the first touch switch is closed, and indicate that lock tongue is still in retracted position.Magnetic switch is closed, then it represents that electromagnet powers off, i.e. the second touch switch disconnects, and lock core does not rotate；Alternatively, door is not closed correctly, electromagnet and the position of magnetic switch be not corresponding.So signal projector is by the cooperation of the first touch switch and magnetic switch, can effective monitoring door and door lock state, for abnormality and alarm, to the risk that avoids theft.

Description

A kind of door latch structure for monitoring door state function

Technical field

The utility model is related to door lock monitoring technology field more particularly to a kind of door lock knots for monitoring door state function Structure.

Background technology

With social development, people increasingly pay attention to safety.And basic tool of the door lock as Domestic anti-theft, hair Exhibition is taken seriously always.

Utility model content

Technical problems based on background technology, the utility model proposes a kind of doors for monitoring door state function Lock construction.

The utility model proposes it is a kind of for monitoring the door latch structure of door state function, including signal projector, signal The magnetic switch that transmitter is sequentially connected in series the first touch switch disconnected under button switch, normality and is closed under normality；

Resilient contact is installed, installation site and the elasticity of the first touch switch are touched in the lock tongue slot on doorframe Point corresponds to；Lock tongue is inserted into the state of lock tongue slot, and resilient contact squeezes the first touch switch and is closed；

Electromagnet is installed, in the state that door is closed, the position of electromagnet is corresponding with magnetic switch, on electromagnet on lock body Under electricity condition, magnetic switch disconnects；Electromagnet is in series with the second touch switch, and contact block, the second touch switch are equipped on lock core In the rotary motion trace of contact block；Second touch switch is closed in the state that lock tongue stretches out.

Preferably, the button of button switch is mounted on the outside of doorframe.

Preferably, signal projector is wirelessly connected preset communicating terminal.

Preferably, communicating terminal uses mobile phone.

Preferably, signal projector is connected with one or more communicating terminal.

The utility model proposes it is a kind of for monitoring in the door latch structure of door state function, when signal projector works, First touch switch and magnetic switch are closed, and the first touch switch is closed, and indicate that lock tongue is still in retracted position.Magnetic control is opened It closes and closes, then it represents that electromagnet powers off, i.e. the second touch switch disconnects, and lock core does not rotate；Alternatively, door is not closed correctly, electromagnetism Iron and the position of magnetic switch be not corresponding.So signal projector can have by the cooperation of the first touch switch and magnetic switch The state of effect monitoring door and door lock, for abnormality and alarm, to the risk that avoids theft.

Fig. 2 be the utility model proposes it is a kind of for monitor door state function door latch structure lock body schematic diagram.

Specific implementation mode

Referring to Fig.1, the utility model proposes it is a kind of for monitoring the door latch structure of door state function, including signal transmitting Device 1, signal projector 1 are sequentially connected in series the first touch switch K2 disconnected under button switch K 1, normality and are closed under normality Magnetic switch K3.When button switch K 1, the first touch switch K2 and magnetic switch K3 are closed, then signal projector 1 sends letter Number.In present embodiment, signal projector is wirelessly connected preset communicating terminal.The mobile phone of kinsfolk can be used in communicating terminal Deng.In this way, when signal projector emits signal, then kinsfolk can be known to judge door lock state in time.

In present embodiment, the button of button switch K 1 is mounted on the outside of doorframe.Button is pressed, then button switch K 1 is closed It closes.In present embodiment, mark that button switch K 1 is monitored as opening door lock.

Resilient contact, installation site and the elasticity of the first touch switch K2 are installed in the lock tongue slot on doorframe Contact corresponds to.Lock tongue is inserted into the state of lock tongue slot, and resilient contact squeezes the first touch switch K2 and is closed.Under normal circumstances, In the case that only door is closed and locked, lock tongue can just be inserted into lock tongue slot, i.e. the first touch switch K2 only door close and on It is closed in the case of lock.

With reference to Fig. 2, electromagnet 2 is installed on lock body, in the state that door is closed, position and the magnetic switch K3 of electromagnet 2 Corresponding, under 2 power-up state of electromagnet, magnetic switch K3 is disconnected.Electromagnet 2 is in series with the second touch switch K4, is installed on lock core There are contact block 3, the second touch switch K4 to be mounted in the rotary motion trace of contact block 3.Contact block 3 is rotated as lock core rotates, when lock core 4 When turning to the position of lock tongue stretching, contact block 3 is against the second touch switch K4, to which the second touch switch K4 is stretched out in lock tongue In the state of be closed, electromagnet 2 it is electric.That is, in the state that door is closed and lock tongue stretches out, magnetic switch K3 is disconnected.

In this way, present embodiment is when it is implemented, press button switch when user goes out, door is closed at this time, and first touches It controls switch K2 to be closed, magnetic switch K3 is disconnected, and sender unit does not work；When magnetic switch closure, then where signal projector 1 Current branch conductive emits signal, door lock abnormality is sent to default object to which signal projector works.

When signal projector works, the first touch switch K2 and magnetic switch K3 are closed, and the first touch switch K2 is closed, Indicate that lock tongue is still in retracted position.Magnetic switch is closed, then it represents that and electromagnet powers off, i.e., the second touch switch K4 is disconnected, Lock core does not rotate；Alternatively, door is not closed correctly, electromagnet 2 and the position of magnetic switch K3 be not corresponding.So signal projector By the cooperation of the first touch switch K2 and magnetic switch K3, can effective monitoring door and door lock state, for abnormality and Alarm, to the risk that avoids theft.

In present embodiment, communicating terminal uses mobile phone, and, signal projector is connected with one or more communication eventually End, is monitored in order to be locked on the door by multiple kinsfolks.

The preferable specific implementation mode of the above, only the utility model, but the scope of protection of the utility model is not Be confined to this, any one skilled in the art within the technical scope disclosed by the utility model, according to this practicality Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model Within enclosing.
