1. And (3) opening a third door when people get on the vehicle:

when the latch of the third door C is unlocked by a key, the door C is opened, the eleventh pin 42 is ejected, the fourteenth pin 33 is ejected after the fifth rotating arm 62, and the second lock pin 672 in the first lock mechanism matched with the fourteenth pin 33 is ejected after the fourteenth pin 33 is ejected, so that the fourth door D and the fifth door E are locked.

After the third door C is opened, the second latch handle 9 moves anticlockwise, the twenty-first pin 70 and the twenty-second pin 57 retract, the sixth pin 7 pops out, the second rotating arm 55 moves clockwise, the first rotating arm 56 is driven to rotate clockwise, and therefore the first pin 5 pops out to lock the first door A.

When the third door C is opened, the first pull pin K1 is in a down state, and the eighth rotating arm 59 rotates to drive the fourth pin 12 to pop up, so as to lock the second door B. When the third door C is opened, the eleventh pin 42 is popped up, and the third pin 53 is popped up after connecting the sixth pivot arm 61 in parallel at the fifth pivot arm 62, thereby locking the second door B. The second latch handle 9 is moved counterclockwise, the second twelve pins 57 are retracted, the twenty-fourth pins 10 are moved leftward, the third rotating arm 38 is rotated to rotate the third rotating shaft 19 so that the protrusions of the third rotating shaft 19 are inserted into the grooves of the twentieth pins 17, thereby locking the second door B.

When the third door C is opened, the first bent arm 43 drives the shift lever 40 to move, the shift lever 40 pushes the second bent arm 39 to move rightward, the second bent arm 39 drives the second bolt 37 to move upward, and the third rotating arm 38 can be prevented from rotating by the cooperation of the second bolt 37 and the fourth stop 73, so that the twenty-fourth pin 10 can be prevented from being prized after the third door C is opened, and the locking of the second door B can be released.

When the third door C is opened, the first bent arm 43 drives the shift lever 40 to move, the shift lever 40 drives the fourth rotating arm 54 to move clockwise, the first bolt 6 and the fourth bolt 52 are pushed upwards, the first pin 5 and the eighth pin 49 are prevented from popping out, the sixth pin 7, the seventh pin 48 and the eighth pin 49 are prevented from being pried by a tool after the third door C is opened, the first door a is opened, and when the first pull pin K1 is prevented from being pulled, the locking function of the first pull pin K1 on the second door B is prevented from being released after the third door C is opened.

2. People get on the vehicle and enter the cab through the first vehicle door A:

after the cash keeper gets on the vehicle, the third vehicle door C is closed, the second bolt handle 9 is rotated clockwise to be in a locking state, the second rotating arm 55 rotates clockwise, the first rotating arm 56 rotates anticlockwise, the first pin 5 moves downwards to release the locking of the first vehicle door A, and the second rotating arm 55 moves clockwise to drive the eighteenth pin 8 to pop out to further lock the third vehicle door C.

After the first door a is opened by the key, the first door a is moved leftward to be opened, and the first push shaft 1 is moved leftward to eject the tenth pin 51 to lock the first door a. After the first door a moves left, the second push shaft 3 is pushed to eject the ninth pin 50, the ninth pin 50 pushes the corresponding first locking mechanism on the first door a to move to the right, the fifteenth pin 31 is ejected, and therefore the fourth door D and the fifth door E are locked by the rightward movement of the first locking mechanism corresponding to the fifteenth pin 31 on the fifth door E.

When the first door a is opened, the second pull pin K2 is pulled up, and the first pull pin K1 is put down, so that the second door B is latched by ejecting the fourth pin 12.

3. Personnel enter the cash box chamber through a second vehicle door B:

the first latch handle 15 on the second door B is rotated in a dark way to one side of the third door C, the first latch handle 15 is rotated to be in an open state, the latch lock of the second door B is unlocked by a key, the second door B is opened, the fifth pin 20 is popped up, the eleventh rotating arm 66 is rotated, the thirteenth pin 34 is popped up to lock the fifth door E, and then the first locking mechanism matched with the thirteenth pin 34 moves rightwards to lock the fourth door D.

After the second door B is opened, the thirty-first pin 21 pops up, the tenth rotating arm 63 rotates to pop up the thirty-first pin 41, and the thirty-first pin 41 moves to the left to push the first locking mechanism matched with the thirty-first pin 41 to move to the left, so that both sides of the third door C are locked.

When the second door B starts, the first latch handle 15 is in the open state, the twentieth pin 17 is retracted, the thirteenth pin 18 is moved to the left, the third rotating shaft 19 is rotated, the third rotating arm 38 is rotated, and the protrusion on the fourth rotating shaft 11 is inserted into the groove of the twelfth pin 57, so that the third door C is locked. Since the first pulling pin K1 is in a pulled-up state when the second door B is opened, the eighth pin 49 pops up to lock the third door C. The second pull pin K2 is in a down state, and the second rotating shaft 4 is inserted into the second stopper 69 to lock the first vehicle door a. When the second door B is opened, the third bolt 35 is moved downwards by the rotating arm 16, and the fifth stop 36 prevents the fourth pin 12 from popping up when the first pull pin K1 is pulled up, so that the situation that the first pull pin K1 is put down after the third door C is opened is prevented.

4. Opening the fourth door:

when the fourth door is opened, the third pull pin K3 must be lowered to release the twenty-seventh pin 32 and the first locking mechanism matching with the twenty-seventh pin 32, and the second door B must be closed after the deposit clerk enters the cash box room. The third latch handle 23 is turned and then the latch on the fourth door D is unlocked with a key to open the fourth door D. When the fourth door D is opened, the sixteenth pin 25 pops up, the thirteenth rocker arm 64 rotates, and the second pin 13 pops up to lock the second door B. When the fourth door D is opened, the seventeenth pin 26 is popped up, the eighth pivot arm 58 rotates counterclockwise, and the first pivot shaft 2 rotates to lock the first door a. When the fourth door D is opened, the third pull pin K3 is lowered, the seventh pin 48 is popped up, and the first lock mechanism engaged with the seventh pin 48 is popped up to lock the third door C.

5. Opening the fifth vehicle door:

because the third latch handle 23 of the fourth door D is connected to three pins, one of which is connected to the fifth door E for locking the fifth door E, the fifth door E can be opened only by the fourth latch handle 22 after the fourth door D is opened. When closing fourth door D and fifth door E, must close first and just can close fourth door D after closing fifth door E, twenty-eight round pin 24 retractions after fourth door D closes, twenty-nine round pin 14 retractions to the contact is to the locking of second door B, and the indoor personnel of paper money case can open second door B and get back to in the carriage, can prevent to forget the circumstances of locking fourth door D bolt lock like this.

6. During the driving process of the armor cash carrier:

in the driving process of the armor cash carrier, the first door A is closed, the first pull pin K1 is pulled up, and the second pull pin K2 is put down, so that the first door A and the third door C are in a locked state, personnel outside the armor cash carrier cannot enter the armor cash carrier, an armor cash keeper cannot enter a cab, the third pull pin K3 in the cab is in a pulled-up state, and the fourth door and the fifth door are locked.
