The application provides a lock interlock system's working process as follows:

the door lock interlocking system is applied to the armor cash carrier, the armor cash carrier is provided with five doors, namely a first door A, a second door B, a third door C, a right rear door D and a right rear door E, wherein the first door A is a side door of a person on the armor cash carrier, the second door B is a door entering a cab from a carriage, and the third door C is a door entering a cash box chamber from the carriage. The second door B and the third door C are both disposed in the vehicle and can only be accessed through the first door A. The first door A, the right rear door D and the right rear door E are hinged with the door seat, and the first door A and the second door B are sliding doors.

1. Opening the first door A: one of the workers swipes a card on the card reading device 1113 at the first door a through the magnetic card 1112, so that the time delay closing switch J1 is closed, the first electromagnetic switch YA1 is powered on to adsorb the tongue fastener 1115, so that the tongue fastener 1115 leaves the groove 1114 on the lock tongue 1111, and then another person inserts a key into a lock hole of the first lock 11 to open the first door a. Because the time of delay closing is set by the delay closing switch J1, the time is temporarily set to be 30 seconds, if the delay closing switch J1 is switched on within 30 seconds, the first vehicle door A is not checked, the delay closing switch J1 is automatically switched off, the first electromagnetic switch YA1 is reset, and the latch 1115 is clamped in the groove 1114. After the first vehicle door a is opened, because the first lock rod 12 and the second lock rod 13 lose the blocking force of the first vehicle door a, under the action of the spring, the first lock rod 12 and the second lock rod 13 spring into the lock holes leftwards, so as to drive the first rotating arm 4 and the second rotating arm 5 to rotate, spring the second lock catch 21 and the third lock catch 31 into the corresponding lock holes, and further lock the second vehicle door B and the third vehicle door C to prevent the second vehicle door B and the third vehicle door C from sliding. After the cash-deposit person enters the carriage, the first door ejects the first lock rod 12 and the second lock rod 13 into the lock holes, so as to drive the second lock catch 21 and the third lock catch 31 to eject the corresponding lock holes, and further the second door B or the third door C can be opened. The latch lock 16 is pressed down, the first vehicle door A is locked again through the fifth lock rod 17 and the sixth lock rod 18, the fifth lock rod 17 drives the first lock catch 14 and the fourth lock catch 15 to move leftwards, and drives the third lock rod 23 and the fourth lock rod 32 to pop out corresponding lock holes, so that a person pressing money can only open the latch lock 16 firstly when getting off, and then presses down the second unlocking switch through a person in a cab to enable the electromagnetic switch and the mechanical switch of the first lock 11 to be opened.

2. Opening the second door B: after the first door a is closed, the second lock 21 is in an unlocked state, and at this time, if the second lock 22 is unlocked, the latch lock 16 is locked, and the third lock rod 23 is ejected out of the lock hole and then the second door B can be opened by a key. After the second door B is opened, the third lock rod 23 loses the blocking force, and is ejected under the action of the spring to drive the third rotating arm 6 to rotate, so as to drive the first lock catch 14 to eject to lock the first door a. Therefore, to open the first door a, the second door B must be in a closed state.

3. Opening the third door C: when the third door C is opened, the first door a and the second door B are both in the locked state, and someone must be in the cockpit, because the third lock 33 on the third door C is an electronic and mechanical integrated lock as the first lock 11, one person presses the first unlocking switch J2 in the cockpit, and the third electromagnetic switch YA3 of the third lock 33 is turned on, so that the tongue 1115 of the third lock 33 leaves the groove 1114, and then the other person opens the banknote door by using the key of the third lock 33. After the third door C is opened, the fourth lock lever 32 on the third door C loses the blocking force and pops up, so as to drive the fourth rotating arm 7 to rotate, and further to pop up the fourth lock catch 15 to lock the first door a. Therefore, to open the first door a, the third door C must be in a closed state.

4. Opening a right rear door D and a right rear door E: since the lock hole of the fourth lock 91 of the right rear door D is installed inside the vehicle, the right and left doors can be opened only after the right rear door E is opened and enters the cash box compartment. The fifth lock 101 on the right rear door E is the same as the first lock 11 on the first door a, and the second electromagnetic switch YA2 on the fifth lock 101 is connected in parallel with the first electromagnetic switch YA1, and both are turned on after the card is read by the card reading device 1113 on the first door a, and then the right rear door E can be unlocked by the key of the fifth lock 101.

When the securicar is powered off due to a accident, the first lock 11 can mechanically make the tongue 1115 leave the groove 1114 through the toggle pin mechanism 8 outside the vehicle, and then the first door a is unlocked through the key of the first lock 11, and under the condition of power off, only the first door a and the second door B can be opened, and the third lock 33 of the third door C and the fifth lock 101 of the right back door E cannot be opened under the condition of power off, and only after power is supplied again, the first door a and the second door B can be opened.

When the securicar needs to be overhauled, the first door A, the second door B and the third door C need to be opened simultaneously for the convenience of entering and exiting. The second door B can be opened by first opening the first door A and pushing the first lock lever 12 against it with a suitable tool. Then, the first unlock switch J2 in the cabin is pressed, and the second lock lever 13 is pressed against by a suitable tool, and then the third door C is opened by a key.

The automobile enters a carriage initially, a key is used for entering the automobile after card swiping, and the key can be used for entering a cockpit after the automobile is closed; and opening the third door, wherein two persons must operate simultaneously, a person in the cockpit presses an unlocking switch button for a long time, and meanwhile, a person in the transportation cabin adopts a key to open and transport the third door, and at the moment, the first door must be in a closed state.

The armor cash carrier provided by the application can prevent the situation of guarding against self-theft after independently opening all doors of the armor cash carrier, and the armor cash carrier provided by the application must at least need two personnel to open the third door, so that the safety of the armor cash carrier is further improved.

The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
