The spring sheet base of the rotating contact piece sensor is fixed at the position opposite to the bottom of the lifting bolt on the outer periphery of the end of the mechanical emergency lock lock cylinder.

[0027] In the specific implementation of the present application, the emergency lock sleeve 1 is fixedly connected with the door body 101, a conventional lock bolt and a lock bolt linkage assembly are arranged on the door body, the mechanical emergency lock lock cylinder 3 and the intelligent electronic lock 6 are connected with the lock bolt linkage assembly of the door body in a common connection manner, the alarm 5 is a common alarm with sound alarm and radio alarm functions in the market, the stop bolt threaded hole 1-1 is arranged at the upper part of the emergency lock sleeve, and the rotating handle 7 is used to adjust and operate the lifting bolt 1-2. The outer thread of the lifting bolt 1-2 is tightly matched with the inner thread of the stop bolt threaded hole, so that the stop bolt can be rotated only when a large enough torsion is applied by the rotating handle 7. When the lifting bolt is manufactured, the height data of the normal opening required alignment groove and the corresponding stop block height are recorded, and the user can use the above data. Under normal circumstances, the emergency lock protection cover 2 is in a closed state, the lifting bolt 1-2 is in the alignment area 2-5 of the limiting sliding groove 2-3, the height of the lifting bolt 1-2 is adjusted, the alignment groove 1-3 is distributed in a misalignment manner with the stop block 2-4, and the opening and closing contacts 4-2 of the rotating contact sensor are not connected. At this time, the intelligent electronic lock of the safe and the lock bolt linkage assembly of the door body can be normally linked to control the opening of the safe door. In order to mark different lifting bolts, a mark is arranged outside the stop bolt threaded hole 1-1. When an emergency occurs and the intelligent electronic lock cannot be used, the special-shaped end 7-3 of the rotating handle 7 is inserted into the stop bolt threaded hole 1-1, the special-shaped end 7-3 is matched with the handle groove 1-4 of the lifting bolt 1-2, the rotating handle 7 is rotated to drive the lifting bolt 1-2 to rotate, the alignment groove 1-3 of the lifting bolt is consistent with the height of the stop block 2-4 on the two sides of the limiting sliding groove, and the scale and characters on the rotating handle which are aligned with the edge of the cover end cap 2-1 are observed as the basis for determining the height of the lifting bolt. The cover end cap 2-1 is pulled outward to drive the cover inner cylinder 2-2 to move outward synchronously, when the limiting sliding groove 2-3 of the cover inner cylinder 2-2 is separated from the lifting bolt 1-2, the cover end cap 2-1 is further rotated to make the clamping ring notch 2-6 on the clamping ring of the cover end cap 2-1 opposite to the outer cover clamping table 1-7, and the cover end cap 2-1 is further pulled outward, so that the emergency lock protection cover 2 is separated from the emergency lock sleeve 1 as a whole. At this time, the key hole of the mechanical emergency lock lock cylinder 3 in the emergency lock sleeve 1 is exposed, the mechanical emergency key is inserted, the mechanical emergency key is used to drive the lock bolt linkage assembly of the door body, and the safe door is opened. If a thief wants to illegally open the safe door by using the mechanical emergency lock lock cylinder, the emergency lock protection cover 2 needs to be opened first. The emergency lock protection cover can be opened only when the heights of multiple lifting bolts are adjusted to be consistent with the heights of the alignment grooves and the stop blocks.The special-shaped boss of the handle groove and the special-shaped end head of the rotating handle are unique, and have a theft-proof effect; rotation of any one lifting pin 1-2 will make the opening and closing contact 4-2 of the rotating contact sensor communicate, the opening and closing contact 4-2 communicates with the starting switch of the alarm, the opening and closing contact 4-2 communicates to start the alarm, the alarm will emit an alarm sound, and send alarm information to the management personnel at the same time, at this time, the thief has not touched the mechanical emergency lock lock core 3, and the alarm will be started. The application starts the early warning program before the mechanical emergency lock is opened, and provides enough response time for the management personnel. The lifting pin adopts a threaded lifting mode, and the emergency lock protection cover can be opened only when the height of the stop block on both sides of the positioning groove of the lifting pin is consistent; the height of the stop block can be divided into several levels, which is equivalent to tens of passwords; a plurality of lifting pins are combined, so that the difficulty of illegal opening is greatly increased, and the anti-theft and early warning performance of the mechanical emergency lock is improved. Compared with the rotating disc type password emergency lock, the application has a more solid structure and is more difficult to be damaged, and has a higher cracking difficulty. In the event of an emergency, when the intelligent electronic lock is damaged or power failure occurs, the emergency lock anti-theft alarm device of the application can manually open the safe door by using a pure mechanical key, and has high reliability and safety.
