[0002] With the continuous improvement of people's living standards, safes or safes have entered the lives of the general public. Traditional safes generally have only one door, but for large safes with large storage space, it is very inconvenient to use one door, so double-door safes have emerged.

[0003] After investigation, the existing Chinese patent with patent number CN201110029172.8 discloses a double-door double-compartment safe, which includes a box body and a first box door and a second box door arranged on one side of the box body. The box body is respectively provided with an inner box storage area and an outer box storage area, and the first box door can just lock the inner box storage area, and the second box door can just lock the first box door and the box body at the same time to lock the outer box storage area. When in use, more valuable items can be placed in the inner box storage area, and other items can be placed in the outer box storage area, and then the first box door is locked first, and then the second box door is locked. Since the first box door is locked by the second box door at the same time, that is, the first box door has double lock protection, the safety factor is higher. This structure improves security and privacy, but the operation is more complicated.

A right upper connecting rod rack is formed on the right side of the lower part of the right upper connecting rod 24 to mesh with the right gear 22. The lower end of the right lower connecting rod 25 on the back of the right cabinet door 2 is fixed to the vertical bolt 20a, and a guide hole is vertically opened at the upper end of the right lower connecting rod 25 to cooperate with the right fixed plate guide column 231 on the right side of the right fixed plate 23. A right lower connecting rod rack is formed on the left side of the upper part of the right lower connecting rod 25 to mesh with the right gear 22, see Figure 4 , 5The slide plate 26 is installed below the right gear 22 so as to slide left and right. A transverse guide hole is provided on the slide plate 26 to cooperate with the right fixed plate guide column 231 on the lower side of the right fixed plate 23. A slide plate rack 261 meshing with the right gear 22 is formed at the upper end of the slide plate 26. The cross bolt 9 is installed on the cross bolt fixing rod, and the right end of the slide plate 26 is fixedly connected to the cross bolt fixing rod. In this way, rotating the left handle 10 and the right handle 20 can drive the left gear 12 and the right gear 22 to rotate, and then drive the left upper connecting rod 14 and the left lower connecting rod 15, the right upper connecting rod 24 and the right lower connecting rod 25 to move up and down, so as to realize the extension and retraction of the left vertical bolt 10a and the right vertical bolt 20a; rotating the right handle 20 can also drive the slide plate 26 to move left and right, so as to realize the extension and retraction of the cross bolt 9.

[0020] The bolt sleeve 7 is a hollow structure. The back of the left cabinet door 1 is provided with a U-shaped lock pin mounting plate 60 on the left side of the bolt sleeve 7. The two sides of the lock pin mounting plate 60 are provided with through holes for the lock pin 6 to penetrate and slide left and right. The lock pin 6 is sleeved with a spring 8, so that the lock pin 6 has a tendency to always move rightward and extend into the bolt sleeve 7. The right side of the lower part of the upper left connecting rod 14 is provided with a right-angle flange that is folded outward and abuts against the left end of the lock pin mounting plate 60. The bayonet 141 is provided at the position of the right-angle flange corresponding to the through hole on the lock pin mounting plate 60. In this way, when the horizontal bolt 9 is inserted, the lock pin 6 moves leftward and is inserted into the bayonet 141 to lock the upper left connecting rod 14. The back of the right cabinet door 2 is provided with an electronic lock actuator 4 for locking the slide plate 26 below the slide plate 26. The electronic lock actuator 4 has an electromagnet, and correspondingly, a locking port 262 is provided at the lower part of the slide plate 26, so that the movable pin of the electromagnet can cooperate with the locking port 262 of the slide plate for locking and unlocking. An emergency lock 4a is also provided on the back of the right cabinet door 2, and the lock column of the emergency lock 4a is connected to the electronic lock actuator 4 through a connecting rod. A swing rod a with a spring is also installed on the back of the left cabinet door 1 and the right cabinet door 2, respectively. The swing rod a is rotatably arranged on the back of the cabinet door through a fixing column and a screw. The spring is pulled between the swing rod a and the gear, so that the swing rod a plays a role in assisting the door closing. A password disk 3 is provided on the upper part of the front surface of the right cabinet door 2, and an emergency lock hole is provided on the lower part of the front surface of the right cabinet door 2.

[0021] Here’s how it works: When in use, first close the left cabinet door 1, at this time, the left vertical door bolt 10a of the left cabinet door 1 extends out and is inserted into the guide hole of the door frame, and the lock pin 6 remains in the extended state under the action of the spring 8, that is, the left cabinet door 1 is unlocked. At this time, the left handle 10 can be turned to open the left cabinet door 1; then the right cabinet door 2 is closed, and the right handle 20 is turned to drive the upper right connecting rod 24, the lower right connecting rod 25 and the slide plate 26 to move, and the right vertical door bolt 20a of the right cabinet door 2 extends out and is inserted into the guide hole of the door frame, and the horizontal bolt 9 on the back side of the right cabinet door 2 is inserted into the bolt sleeve 7 on the back side of the left cabinet door 1 to lock the left cabinet door 1, and the lock pin 6 is pushed to the left by the horizontal bolt 9 and is clamped in the bayonet 141, so that the upper left connecting rod 14 cannot move up and down, and the left cabinet door 1 reaches the locked state, and the right cabinet door 2 is also locked.

[0022] When unlocking, the user inputs the correct password, so that the control circuit of the safe cabinet can trigger and drive the electronic lock actuator 4 to move, and the lock of the slide plate 6 is released. The user only needs to rotate the right handle 20, drive the slide plate 26 to move to the right through the right gear, realize the retraction of the horizontal bolt 9, and move the right upper connecting rod 24 and the right lower connecting rod 25 to realize the retraction of the right vertical door bolt 20a, and the right cabinet door 2 can be opened; due to the retraction of the horizontal bolt 9, the lock pin 6 moves to the bolt sleeve 7 side under the action of the spring 8, so that the lock pin 6 moves out of the bayonet 141, and the lock of the left upper connecting rod 14 is released, so that the left handle 10 can be rotated, and the left cabinet door 1 can be easily opened. When the control circuit fails or the power is off, the emergency lock 4a can be used to replace the electromagnet in the electronic lock actuator 4, and the emergency lock can be opened with a key.

[0023] The safe cabinet described in this article refers to a relatively large safe or a relatively small safe.

[0024] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
