Description

a door lock

technical field

The utility model relates to a door lock, in particular to an automatically unlockable door lock.

Background technique

As we all know, dormitories in public places such as factories and campuses are generally shared by multiple people. When someone forgets to bring the key or a friend comes to the dormitory, they often need to run to open the door again and again, especially at night when the weather is cold or everyone is already in bed. During the break, if someone knocks on the door, people are often reluctant to go down and open the door.

In response to this problem, people have begun to solve it. For example, the Chinese patent application number CN201420714542.0 discloses an automatic opening device for student dormitory door locks. Automatic opening of the door lock. Another example is the Chinese patent whose application number is CN201420714569.X, which discloses a device for automatically opening the door lock of a student dormitory, which realizes the automatic opening of the door lock through the mutual transmission of the rotating shaft, support rod, wire drawing, etc. However, the above-mentioned disclosed technical solutions have complex structures and many mechanical parts, and over time, the operational reliability will be reduced, and the subsequent maintenance costs will be relatively high.

Contents of the invention

The purpose of the utility model is to provide a simple and convenient structure, which can realize the automatic opening of the door lock remotely, and can be widely used in public dormitory fields such as schools and factories.

In order to achieve the above object, the utility model adopts the following scheme.

A door lock, including a lock body and an unlocking assembly fixedly installed on the door leaf, and a buckle seat fixedly installed on the door frame, the unlocking assembly includes a Bluetooth signal receiving device installed on the outside of the door leaf, installed on the door leaf The inner handle, the controller installed in the lock body, the lock core, the lock shaft, the lock core drive motor, and the lock end connected to the lock core by a spring; the main shaft of the lock core drive motor is connected to the The lock cylinder is keyed, and the main shaft of the lock cylinder drive motor is also connected with the lock shaft through a coupling, and the lock shaft is also connected with the handle.

The lock core is provided with grooves along its circumferential direction.

A block is arranged inside the lock body, which is a limiting device for the rotation stroke of the lock cylinder.

A battery is installed in the Bluetooth signal receiving device to provide power output for the Bluetooth signal receiving device and the lock cylinder driving motor.

The door lock can only be unlocked through Bluetooth signal identification on the outside, and can also be unlocked on the inside by rotating the door handle.

Through the above technical scheme, the utility model has the following advantages compared with the prior art: the utility model can send a signal to the Bluetooth information number receiving device of the corresponding door lock through electronic equipment such as a mobile phone, and the controller controls the lock cylinder to drive the motor to work to realize the door lock. The lock can be opened automatically; the structure is simple and convenient, and has great application prospects in public dormitory fields such as schools and factories.

detailed description

Further illustrate the utility model below in conjunction with accompanying drawing.

As shown in Figures 1, 2, 3, and 4: a door lock includes a lock body 2 fixedly installed on the door leaf and an unlocking assembly, and a buckle seat 5 fixedly installed on the door frame. The bluetooth signal receiving device 6 on the outside of the door leaf, the handle 11 installed on the inside of the door leaf, the controller 7 installed in the lock body, the lock cylinder 9, the lock shaft 1, the lock cylinder drive motor 8, and the spring 3 The lock head 4 that is connected with the lock core 9; the main shaft of the lock core drive motor 8 is keyed to the lock core 9, and the main shaft of the lock core drive motor 8 is also connected to the lock shaft 1 through a coupling connected, the lock shaft 1 is also connected with the handle 11 .

The lock cylinder 9 is provided with a groove 9-1 along its circumferential direction.

A block 10 is arranged inside the lock body 2, which is a limiting device for the rotation stroke of the lock cylinder 9.

A battery is installed in the Bluetooth signal receiving device 6 to provide power output for the Bluetooth signal receiving device 6 and the lock cylinder driving motor 8 .

The door lock can only be unlocked by Bluetooth signal identification on the outside, and can also be unlocked by rotating the door handle 11 on the inside.

When unlocking outside the door, first turn on the bluetooth switch of electronic equipment such as mobile phones, connect with the described bluetooth signal receiving device 6 according to the password set in advance, after completing the connection, send the unlocking instruction, and the described bluetooth signal receiving device 6 receives the signal , and control the lock cylinder driving motor 8 to rotate counterclockwise through the controller 7, the main shaft of the lock cylinder driving motor 8 drives the lock cylinder 9 to rotate counterclockwise through the key until it stops contacting the stopper 10, and in the process, the spring 3 Drive the lock head 4 to move to the inside of the lock body 2 to realize unlocking.

When unlocking indoors, in addition to using the above scheme to unlock, the handle 11 can also be rotated directly clockwise. The lock shaft 1 drives the main shaft of the lock cylinder driving motor 8 to rotate through the coupling, and the main shaft of the lock cylinder driving motor 8 drives the lock cylinder 9 to rotate. Clockwise rotation, during this process, the spring 3 drives the lock head 4 to move to the inside of the lock body 2 to realize unlocking.

When locking the door, after sending the lock command, the internal device performs the corresponding inverse operation according to the above principle, and then the door can be automatically locked.

The above description is only proposed as a technical solution that can be implemented in the utility model, and not as a single restriction on the technical solution itself. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the utility model are valid Should be included in the scope of protection of the present utility model.
