fourth springs

203d and 203 e.

In summary, when the baffle 202 is to be closed, the baffle 202 is rotated to make the lock head 301 enter the lock box 203 through the lock hole 304, and at this time, the first sliding block 303a is in the initial position, the second sliding block 303b is in the longest position relative to the first sliding block 303a, the second pushing plate 303b-1 is in contact with the first baffle 303c-1, the second baffle 303c-2 is in contact with the support plate 302a, and the claw 303b is in the open state; while the third spring 203d is in a compressed state, pushing the trigger blocks 303a-42 to place the flip card 303a-4 in a non-engaged position.

Note that, the second spring 203b is also in a stressed state at this time, and acts on the first slider 303a together with the third spring 203d to achieve the balance of forces.

After the lock head 301 enters the lock box 203, the lock head 301 is firstly contacted with the first push plate 303b-1 and pushes the first sliding block 303a to move away from the initial position, the second sliding block 303b moves along with the first push plate 303b, and the claw 302b is in an open state, so that the lock head 301 and the first push plate 303b-1 are not influenced to move inwards, and then the lock head 301 and the first push plate 303b-1 move to be contacted with the first baffle 303c-1 and continue to push the push rod 302c to move, and when the push rod 302c is in the second position, the claw 302b is folded.

At this time, the biasing force on the flapper 202 is removed, and the flapper 202 will return under the action of the torsion spring, so that the lock head 301 will move to the position of the lock hole 304, and the first slide block 303a will follow the lock head 301 to return under the action of the second spring 203 b. Since the second sliding block 303b is located at the longest position relative to the first sliding block 303a in this process, and the distance c is greater than the distance a, the second pushing plate 303b-1 does not contact with the first blocking plate 303c-1 in the process of returning the first sliding block 303a, so the pushing rod 302c is still located at the second position, the claws 302b are still folded, and the lock head 301 is clamped by the claws 302b in the process of returning and cannot leave the lock box 203, thereby clamping and closing the blocking plate 202.

When the baffle 202 needs to be opened again, the baffle 202 only needs to be pushed into the inner cavity 105 again, the lock head 301 leaves the claw 302b, the first push plate 303a-1 is continuously pushed to move inwards, the first push plate 303a-1 drives the push rod 302c to act again, after the second push plate 303b-1 contacts the supporting plate 302a, the second sliding block 303c stops moving, the first sliding block 303a moves relative to the second sliding block 303b until the second sliding block 303b is located at the shortest position on the second sliding block 303a, at this time, the first sliding block 303a stops moving, namely, the lock head 301 cannot move forwards any more, and at this time, the push rod 302c is located at the third position; in this process, the fourth spring 203e applies a force to the trigger blocks 303a to 42 to make the flip card 303a to 4 in the engaging position, so that when the second sliding block 303b is located at the shortest position on the second sliding block 303a, the first hooks 303a to 41 engage with the second hooks 303b to 3, so as to make the first pushing plate.

When the force applied to the baffle 202 is removed, the baffle 202 rotates under the action of the torsion spring, the lock head 301 moves towards the lock hole 304, the first sliding block 303a returns to the initial position under the action of the second spring 203b, the push rod 302c is still at the third position, the first push plate 303a-1 is separated from the first baffle 303c-1, the second sliding block 303b and the first sliding block 303a are locked to be at the shortest position, after the first sliding block 303a moves for a distance a, the second push plate 303b-1 starts to contact with the first baffle 303c-1 and drives the push rod 302c to move towards the first position, when the push rod 302c moves to the first position, the second baffle 303c-2 contacts with the support plate 302a and cannot move any more, in the process, the claw 302b is opened from closing to opening, in the process from the second position to the first position, the claw 302b is in the closing state, meanwhile, as the distance b is smaller than the distance a, the distance from the first push plate 303a-1 to the first baffle 303c-1 is smaller than the distance from the end of the claw 302b to the first baffle 303c-1, that is, the lock head 301 in contact with the first push plate 303a-1 is still positioned between the end of the claw 302b and the first baffle 303c-1, the push rod 302c is continuously driven to move, the claw 302b is slowly opened, and the lock head 301 is away from the clamping range of the claw 302b until the push rod 303c is positioned at the first position.

When the push rod 303c is at the first position, the second push plate 303b-1 is limited by the first stop block 303c-1, so that the second slide block 303b stops moving, the fourth spring 203e no longer contacts the trigger block 303a-43, the third spring 203d contacts the trigger block 303a-43 and enables the flip block 303a-4 to be in the non-engagement position, and then the first slide block 303a moves relative to the second slide block 303b under the action of the second spring 203b until the second slide block 303b is at the longest position of the first slide block 303a, and at this time, the first slide block 303a is at the initial position; while the lock cylinder 301 continues to move away from the lock box 303.

In summary, the user only needs to slightly push the baffle 202 to make the lock head 301 enter the lock box 203 for a certain distance, and the lock head 301 is locked when the lock head 301 is released, and the baffle 202 is closed; the flap 202 is pushed once again by the force, and the flap 202 is ejected after being released.
