The working process of the utility model comprises the following steps:

initial state:

referring to fig. 1 to 4, when the door hook is inserted to turn the latch hook 2, the latch hook stopper 6 needs to be pushed to the right against the force of the fourth spring 70. The fourth spring 70 applies a force to the switch fixing bracket 7, and transmits the force to the limiting block switch 4 through the switch fixing bracket 7, the force to the locking hook limiting block 6 through the limiting block switch 4, and the force to the locking hook 2 through the locking hook limiting block 6. The step 41 of the stopper switch 4 is overlapped with the step groove 62 of the lock hook stopper 6. The tail part of the switcher driving rod 3 is provided with a first spring 30, so that the switcher driving rod 3 can move to the right, and the switcher driving rod 3 has a reset function.

Door closing state:

referring to fig. 6, when the door hook is inserted along the arrow position, the latch hook 2 is driven to rotate anticlockwise to drive the switch driving rod 3 to move leftwards, and the positioning needle 5 on the limiting block switch 4 moves from the a position to the b position, as shown in fig. 15. After the door hook stops being inserted, the latch hook 2 rotates clockwise under the action of the reset torsion spring 20 until the latch hook stops rotating after being blocked by the locking inclined surface 61 of the latch hook limiting block 6. At this time, the driving projection 21 of the latch hook 2 is separated from the driving groove 31 of the switch driving lever 3, the switch driving lever 3 moves rightward under the action of the first spring 30, the positioning needle 5 moves from b to c, and the closing operation is completed. In the process from a to b, the positioning needle 5 drives the limiting block switcher 4 to rotate for a certain angle. However, the stopper switch 4 and the latch stopper 6 still maintain the overlapping state. The force of the fourth spring 70 still acts on the latch hook, preventing the latch hook 2 from continuing to flip.

Pushing and flicking door opening state:

in the door closing state, the door is closed again, so that the door hook is continuously inserted inwards, the lock hook 2 is driven to rotate anticlockwise, and the lock hook 2 drives the switcher driving rod 3 to continuously move leftwards. The positioning needle 5 moves from c to d, the positioning needle 5 drives the limiting block switcher 4 to continue rotating by a certain angle, at this time, the step 41 of the limiting block switcher 4 is separated from the step groove 62 of the locking hook limiting block 6, the overlapping parts of the step 41 and the step groove are separated, the locking inclined surface 61 of the locking hook limiting block 6 does not apply resistance to the locking hook 2 any more, the fourth spring 70 does not act on the locking hook limiting block 6 any more (the process is that the component directly acted by the acting force of the fourth spring 70 is the switcher fixing bracket 7 and is transmitted to the limiting block switcher 4 through the switcher fixing bracket 7), the locking hook 2 is reset under the action of the reset torsion spring 20 after the closing action of the limiting block switcher 4 and the locking hook limiting block 6 is eliminated again, and the door is opened.

The above embodiments are illustrative of the present utility model, and not limiting, and any simple modifications of the present utility model fall within the scope of the present utility model.
