Abstract

The electronic handle lock is mainly composed of a front handle assembly 1, a rear handle assembly 2, a latch bolt lock bar 3 and a square rod 4. The electronic dead lock part is mainly composed of a lock cylinder assembly 5, a dead lock electric drive module 6 and a dead bolt lock bar 7, and the front face of the dead lock electric drive module 6 is provided with a rotary knob 6-1 capable of rapidly opening or closing a dead bolt, a battery cover 6-2 and a rotary knob shaft 6-3 which is coaxially and fixedly connected with the rotary knob 6-1 and provided with a cross-shaped notch. The lock cylinder assembly 5 is used for emergency unlocking, and the situation that when an electronic part is damaged and cannot be normally used, emergency unlocking can be achieved through a key is prevented. When the front handle assembly 1 is in a standby working condition, the handle is in a free state, if biological recognition succeeds, one signal sends an instruction to an internal electric control mechanism to convert the handle into a linkage state, and the handle is restored to the free state after set time is up. And the other path of signal is transmitted to the dead lock electric drive module 6 in a wireless communication manner to drive the dead bolt to withdraw, so that the aim of synchronously unlocking the inclined bolt and the dead bolt is fulfilled. If the dead lock needs to be locked, any number key on the front handle only needs to be pressed for about three seconds for a long time, and the dead lock electric drive module 6 receives a transmitted instruction signal to drive the dead bolt to stretch out to complete locking.

Description

Technical Field

[0001] The present invention relates to the field of intelligent locks for doors, and specifically refers to a door lock with an electronic handle lock and a deadlock linkage control for unlocking. Background Art

[0002] Among various door locks with different shapes and functions in appearance, there is a mechanical door lock assembled and used with an inclined tongue lock and a dead tongue lock. The inclined tongue lock and the dead tongue lock are two independent main bodies for separate use. In actual use, the main function of the inclined tongue is to automatically pop out and lock the door after closing, but the inclined tongue lock and the handle are linked and uncontrolled, and the inclined tongue can be retracted by simply pressing down the handle. The deadlock is controlled, and each operation requires a key to drive the lock core to control the opening or closing of the dead tongue. The resulting problem is that the inclined tongue only locks the door when it is closed, and can be retracted by pressing down the handle, while outside the door, whether it is locking or unlocking the deadlock, manual intervention with a key is required to achieve the purpose of locking or unlocking. Summary of the Invention

[0003] In summary, the purpose of the present invention is to provide a door lock with an electronic handle lock and a deadlock linkage control for unlocking, which solves the problems of the conventional mechanical handle lock that the inclined tongue only locks the door when it is closed but is uncontrolled, and that whether it is unlocking or locking the deadlock, manual intervention with a key is required.

[0004] The present invention consists of two main bodies: an electronic handle lock and an electronic deadlock. The electronic handle lock mainly consists of a front handle assembly, a rear handle assembly, an inclined tongue lock, and a square rod.

[0005] The electronic deadlock mainly consists of a lock core assembly, a deadlock electric drive module, and a dead tongue lock. Among them, the lock core assembly is used for emergency unlocking. When the electronic part is damaged and cannot be used normally, a key can be used for emergency unlocking.

[0006] The working principle of the present invention is that when the front handle assembly is in the standby condition, the handle is in a free state, and pressing down the handle cannot control the retraction of the inclined tongue. If biometric identification is successful, one signal is sent to the internal electric control mechanism to rotate forward, and within the set time, the free state of the handle is converted to the linked state. Pressing down the handle can drive the inclined tongue to retract. When the set time is reached, the electric control mechanism rotates in reverse and returns the handle to the free state. Another signal is transmitted to the deadlock electric drive module through wireless communication to drive the dead tongue to retract, thus achieving the purpose of synchronous unlocking of the inclined tongue and the dead tongue.

[0007] If it is necessary to lock the deadlock, just long-press any number key on the front handle for about three seconds. The front handle assembly sends a locking signal instruction to the deadlock electric drive module through wireless communication to drive the dead tongue to extend and complete the locking. Description of the Drawings

[0008] Appendix Figure 1 : Schematic diagram of the structural composition of the electronic handle lock of the present invention.

[0009] Appendix Figure 2 : Schematic diagram of the structural composition of the electronic dead lock of the present invention.

[0010] Appendix Figure 3 : Front view of the dead lock electric drive module of the present invention.

[0011] Appendix Figure 4 : Rear view of the dead lock electric drive module of the present invention. Specific embodiments

[0012] The electronic handle lock part of the present invention mainly consists of a front handle assembly 1, a rear handle assembly 2, an oblique tongue lock 3, and a square rod 4.

[0013] The electronic dead lock part of the present invention mainly consists of a lock core assembly 5, a dead lock electric drive module 6, and a dead tongue lock 7. Among them, on the front of the dead lock electric drive module 6, there are a knob 6-1 and a battery cover 6-2 that can be used to quickly open or close the dead tongue (below the battery cover is a battery compartment for installing batteries), and a knob shaft 6-3 that is fixedly connected coaxially with the knob 6-1 and has a cross slot.

[0014] The installation method of the electronic handle lock of the present invention is the same as the operation method of the traditional mechanical lock structure. The square rod 4 passes through the square hole of the oblique tongue lock 3 and is respectively connected to the front handle assembly 1 and the rear handle assembly 2 (as shown in Appendix Figure 1 ).

[0015] The installation method of the electronic dead lock of the present invention is also similar to that of the traditional mechanical lock structure. The tail ruler of the lock core assembly 5 passes through the dead tongue lock 7 and is inserted into the cross slot of the knob shaft 6-3 of the dead lock electric drive module 6 to form a connection (as shown in Appendix Figure 2 ).

[0016] The tail ruler of the lock core assembly 5 has a free angle of about 120 degrees with the lock cylinder. When the knob 6-1 or the electric drive rotates the knob shaft 6-3 with a cross slot within a certain angle range, there will be no interference or jamming with the lock cylinder. Similarly, when the lock core is used to open the dead tongue, the lock core also needs to be rotated to the designed angle first to control the tail ruler to drive the dead tongue to lock or unlock.
