principle of unlocking

1. Electronic unlocking: the method comprises the steps that a confirmation key 4 on a lock key is lightly pressed, a communication module of the lock uploads a request to be unlocked to a cloud end upper computer of a data center at a PC (personal computer) end of a control platform, after the data center distinguishes information of the lock, an unlocking password is issued to a terminal mobile phone or handheld equipment of an unlocking person on site, the unlocking person inputs a correct password on the key 4, a lock main control circuit board 10 issues an unlocking instruction to a micro-motor, a cam 20 is arranged to rotate by 90 degrees, a double-arm lock pin transmission mechanism 23 is shifted to shift the double-arm lock pin transmission mechanism 23 to slide downwards to be separated from a clamping groove position of a handle head 18, a lock handle 1 is pressed by a 90-degree stainless steel lock bolt 27 to achieve the unlocking purpose along with the lock handle 1, and the double-arm lock pin transmission mechanism 23 presses a micro-stroke limit switch A15 and triggers an unlocking success instruction, so that unlocking information is reported to a storage chip and uploaded to the data center.

2. Unlocking by a mechanical key: when the control electric box is in abnormal power failure or the lock cannot be opened through electronic unlocking, an unlocking person needs to buckle the mechanical keyhole silica gel waterproof cover 12 out, the mechanical key 13 is taken out and is aligned with a lock hole to be inserted into the lock hole to rotate 90 degrees clockwise, the limiting rod on the lock core 17 stirs the double-arm lock pin transmission mechanism 23 to slide downwards to be separated from the clamping groove position of the handle head 18, the lock handle 1 automatically slides downwards 90 degrees, the stainless steel lock tongue 27 downwards follows the lock handle 1 to achieve the unlocking purpose, and the double-arm lock pin transmission mechanism 23 presses the micro-motion limit switch A15 and triggers an unlocking success instruction, so that unlocking information is reported to the storage chip and is uploaded to the data center.

And (3) locking principle:

1. electronic lock closing: after the lockset is successfully unlocked, in a set time, a locking instruction is sent by the lockset main control circuit board 10, the micromotor drives the cam 20 to rotate forward by 90 degrees, the double-spring propulsion device 22 releases thrust to slide the double-arm lock pin transmission mechanism 23 upwards to prop against the excircle of the handle head 18, when the lock handle 1 is lifted upwards by 90 degrees, the double-arm lock pin transmission mechanism 23 automatically slides into the clamping groove position of the handle head 18 to achieve the locking purpose, and the locking information is reported to the storage chip and is uploaded to the data center as the motor cam 20 presses the micro-stroke limit switch B21 and triggers the locking success instruction.

2. Closing the lock by a mechanical key; after the mechanical key 13 is successfully unlocked, the mechanical key 13 is rotated 90 degrees anticlockwise to be pulled out of the mechanical key 13, the two spring supports 19 in the double-spring propelling device 22 release thrust, the double-arm lock pin transmission mechanism 23 slides upwards to prop against the excircle of the handle head 18, when the lock handle 1 is lifted 90 degrees upwards, the double-arm lock pin transmission mechanism 23 automatically slides into the clamping groove position of the handle head 18 to achieve the purpose of locking, and due to the fact that the micro travel limit switch A15 leaves the position of the double-arm lock pin transmission mechanism 23 and triggers a command of successful locking, locking information is reported to the storage chip and is uploaded to the data center.
