[0002] In the locks currently on the market that have an electromechanical interlocking function (a function in which the lock can be unlocked by a key only when the electronic actuator fails), the design of the electromechanical interlocking device is unreasonable, which is not conducive to the modular design of the electromechanical interlocking device. The electromechanical interlocking device is directly assembled on the lock housing with parts, which makes the assembly and production of the lock inconvenient; and it brings inconvenience to the installation and application of the electromechanical interlocking device on different types of electronic locks. Summary of the invention

[0003] The purpose of the utility model invention is to overcome the defects of the prior art and provide a kind of object interlocking lock with reasonable structural design and modular design.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A physical lock, comprising a lock shell, a handle pivotally mounted on the lock shell, and a handle lock device for locking / unlocking the handle, wherein the handle is provided with a locking portion corresponding to the handle lock device, the handle lock device comprising a mechanical lock core mechanism and an electric locking mechanism, the electric locking mechanism comprising an electromagnet, a lock tongue, a reset tongue, and a reset spring for driving the reset tongue to reset, the lock tongue is driven to slide by the iron core of the electromagnet, the reset tongue is linked to the lock tongue to push, the mechanical lock core mechanism comprises a lock core and a lock core push rod component driven by the lock core, the lock core push rod component has an unlocking portion for pushing the reset tongue to drive the lock tongue to unlock the handle and a secondary locking protrusion for temporarily locking the handle, the lock core push rod component has a one-time unlocking action The invention relates to a lock mechanism for locking the lock core and a secondary unlocking stroke. During the first unlocking stroke, the secondary locking protrusion locks the handle and the unlocking part pushes the lock tongue to disengage the locking part through the reset tongue, and the lock core push rod component is reset after the secondary unlocking stroke. The invention is characterized in that: the handle lock device also includes an electric module skeleton and a lock core module skeleton, the electric locking mechanism is assembled on the electric module skeleton to form an electric module, the mechanical lock core mechanism is integrated and assembled on the lock core module skeleton to form a lock core module, the electric module and the lock core module are installed on the lock housing and are arranged relatively on both sides of the locking part, the unlocking part and the secondary locking protrusion protrude toward the direction of the electric module, and a lock core locking part cooperating with the secondary locking protrusion for locking / unlocking is provided on the handle.

[0006] By adopting the above technical solution, when the lock core is unlocked, the lock core drives the lock core push rod component to move. During one unlocking stroke, the secondary locking protrusion on the lock core push rod is locked with the lock core locking part, the handle is locked, the unlocking part of the lock core push rod pushes the reset tongue, the reset tongue pushes the lock tongue, the lock tongue disengages from the locking part, and the lock tongue releases the lock of the handle.

The lock core is continuously rotated to unlock, the lock core push rod enters the secondary unlocking stroke and is finally reset, that is, the secondary locking protrusion on the lock core push rod component is locked with the lock core. When the electric locking mechanism and the mechanical lock core mechanism are unlocked, the unlocking part releases the pressure on the reset tongue, and the reset tongue is reset under the drive of the reset spring. If the electromagnet is still effective, the electromagnet will drive the lock tongue to re-lock the handle. When the electromagnet fails or the mechanical unlocking command is given, the electromagnet will remain in the unlocked state, thereby completing the lock core unlocking action; the electric locking mechanism and the mechanical lock core mechanism adopt independent skeleton assembly to achieve modular design, which facilitates the assembly and maintenance of the lock and improves the production and assembly efficiency; the modular design of the electric locking mechanism and the mechanical lock core mechanism can adapt to the design requirements of different lock products.
