Description
Technical Field
The invention relates to the technical field of door locks, in particular to a closeable lock cylinder, a digital door lock and a closing method thereof.
Background
In general, for security and security, doors for home or business and stores are provided with door locks, in recent years, mechanical door locks have been replaced with digital door locks.
In order to activate these digital door locks, a method of touching an electronic key to a touch portion of the electronic key, a method of pressing a key pad using a mechanical switch such as a tact switch or a membrane switch to input a password, and a method of using a fingerprint have been conventionally employed.
Existing digital door locks generally include: a panel and a lock cylinder disposed in the door; the lock cylinder includes a cam and a motor that drives the cam to rotate. When the user inputs the correct key, the motor drives the cam to rotate, and finally the lock bolt of the door lock is unlocked. However, all door locks have the problem of higher dependence on a power supply, and once the power supply is disconnected from a motor, the door lock cannot be opened, so that the reliability is low.
In the prior art, a mechanical key core is additionally arranged on the basis of a digital door lock, the key core is in a bullet type or blade type, and a user can insert a physical key to unlock the door lock besides normally inputting a secret key to unlock the door lock. In the prior art, the two unlocking modes are available at the same time, and the existence of the physical key core provides conditions for technical unlocking and leaves security holes for the digital door locks.
Disclosure of Invention
In view of this, the present invention provides a lock cylinder that can be closed.
The aim of the invention is achieved by the following technical scheme: a closeable lock cylinder includes a cam for actuating a lock cylinder, a key cylinder disposed at one end of the cam, the cam including a sleeve and an engagement portion extending radially from the sleeve; the key core is coaxial with the sleeve, the tail end of the key core is in transmission connection with the sleeve through a first clutch device extending into the sleeve, and the key core further comprises a clutch locking assembly, wherein the clutch locking assembly comprises a top block which can be slidably arranged in the sleeve, and a limiting assembly for locking the position of the top block.
The cam, the key core and the first clutch device can be realized by the prior art. After the key is inserted into the key core, the key core can be pushed to move towards the sleeve, and finally the first clutch device is pushed into the sleeve to realize transmission connection with the sleeve. At this time, the key core is rotated to drive the engagement portion to rotate, so that the lock bolt of the door lock is finally moved. The above are all in accordance with the prior art. The invention is especially provided with the clutch locking component, the limiting component can lock the ejector block in the sleeve, prevent the first clutch device from entering the sleeve, and realize the aim of sealing the lock cylinder. After the lock core is closed, the door lock cannot be unlocked by rotating the key core, so that the aim of improving the safety of the mechanical door lock is fulfilled. When the key core is used for unlocking, the limit assembly is unlocked to the top block, and the first clutch device can push the top block open to enter the sleeve to realize transmission connection.
Further, the front end of the top block extends into the sleeve from the other end of the cam; the tail end of the top block is also connected with a reset mechanism; the limiting assembly comprises at least one limiting groove which is opened on the side face of the top block and is arranged along the radial direction of the top block, a limiting bolt which is arranged on the outer side of the top block and is matched with the limiting groove, and a first driving mechanism which drives the limiting bolt to insert into/withdraw from the limiting groove.
After the unlocking action is finished and the pushing force applied to the key core is eliminated, the reset mechanism can push the top block into the sleeve again, release the connection state of the first clutch device and the sleeve, and improve the safety of the lock core. And meanwhile, the locking of the limiting assembly to the top block is convenient to start at any time. Particularly preferably, the invention selects the limit groove and the limit bolt as the limit components, and the limit bolt can be inserted into or withdrawn from the limit groove under the drive of the first driving mechanism. After the limiting bolt is inserted into the limiting groove, the limiting bolt and the limiting groove are mutually meshed to enable the top block to be unable to move, and the purpose of locking the top block in the sleeve is achieved. After the limit bolt exits the limit groove, the locking of the top block is released, and the first clutch device can push the top block out of the sleeve to be meshed and connected with the sleeve. The first driving mechanism can be realized by any one of the prior art, such as an electromagnetic valve, an air cylinder, a motor and the like. The limiting groove and the limiting bolt are adopted as limiting components, so that the limiting device is simple in structure, high in reliability, easy to realize and beneficial to popularization and application.

When the lock core is applied to the digital door lock, the mechanical lock core operated by the key core can be closed when the digital door lock works normally, so that technical unlocking is avoided, and the safety of the digital door lock is improved. Once the digital door lock has faults such as power failure, the lock cylinder can be closed, and a user can unlock the door lock by inserting a physical key. In addition, the mechanical lock cylinder can be in a normally open state, and when abnormal operation such as technical unlocking is detected, the lock cylinder is closed, so that the safety of the door lock is improved. The digital door lock also comprises necessary data processing structures, key input structures, door lock driving structures and other necessary structures, and the digital door lock is not improved by the invention, so that the digital door lock is not described in detail and can be realized by any prior art.
Further, the device also comprises a control unit and a detector, wherein the detector is in communication connection with the control unit, and the control unit is in communication connection with the first driving mechanism.
The detector is used for detecting the working state of the digital door lock, and when the digital door lock is abnormal (the power supply cannot normally supply power, abnormal operation occurs, and the like), the control unit can judge and send out an instruction for closing and opening the lock cylinder, so that the first driving mechanism drives the limit bolt to be inserted into/withdrawn from the limit groove. The type and number of detectors and their configuration can be set according to the state to be detected. For example, if the power supply condition is required to be detected, a current and voltage detector is arranged in the related circuit to detect the current and voltage values in the system, and the current and voltage values are used for judging the power supply condition. The control unit can be any prior art, such as a singlechip.
