The locking tongue 200 is provided with a blocking part 210 for blocking the locking block 300, the sliding fit between the locking tongue 200 and the main body 100 is opened and closed by the matching of the blocking part 210 and the locking block 300, and the locking block 300 and the blocking part 210 are positioned on the same horizontal plane in a locking state, so that the locking tongue 200 cannot reciprocate.

The quantity of fender portion 210 is two and arranges in the both sides of lock core subassembly 500, and latch hook 700 and tapered end 230 cooperate and carry out the locking to case and bag, and the quantity of fender portion 210 is preferred to be 2 and has guaranteed the reciprocating motion of spring bolt 200 and the stability of locking piece 300 complex when considering the volume.

The lock cylinder assembly 500 includes a pick 510 for forcing the lock block 300 to disengage from the blocking portion 210, the pick 510 is rotatably connected to the main body 100, and the locking step and the second unlocking step are switched by the relative rotation of the pick 510 and the main body 100.

The shifting piece 510 is provided with a guide surface 511 for facilitating the conversion from the locking gear to the second unlocking gear, the locking block 300 is provided with a guide block 310 matched with the guide surface 511, and the guide surface 511 can be designed into an inclined surface for lifting the locking block 300.

The main part 100 is provided with a limiting column 110 for assembling the lock cylinder assembly 500, the limiting column 110 is used for assembling the lock cylinder assembly 500, the lock cylinder assembly 500 is a mature technology in the market, and the key can be used for rotating the poking piece 510 without repeated description.

The limiting column 110 is provided with a limiting block 111 for limiting the rotation of the pick 510, and the limiting block 111 is used for preventing the pick 510 from excessively rotating.

The main body 100 is provided with a groove 120 for limiting the reciprocating motion of the latch bolt 200, and the groove 120 is used for assembling the latch bolt 200 and limiting the same.

The locking tongue 200 is provided with a first elastic mechanism 220 for forcing the locking tongue 200 to be far away from the locking block 300, and the first elastic mechanism 220 is used for resetting the locking tongue 200 and preventing unlocking.

The second elastic mechanism 320 for forcing the locking block 300 to switch from the locking position to the first unlocking position is arranged on the locking block 300, the first elastic mechanism 220 and the second elastic mechanism 320 can adopt spring mechanisms, the cost is low, the assembly is convenient, and the second elastic mechanism 320 forces the locking block 300 to abut against the code wheel 410.

And (3) locking state:

due to the password error of the password assembly 400, the password wheel 410 lifts up one end of the lock block 300 along the edge to support the blocking part 210 of the bolt 200, and at this time, the end of the lock block 300 is in the same horizontal plane with the blocking part 210 of the bolt 200, so the bolt 200 cannot be unlocked by moving towards the lock block 300;

in a locked state, when a password needs to be entered for unlocking, and the password is correct, the groove 411 on the password wheel 410 corresponds to the protrusion 330 of the lock block 300, and in addition, the second elastic mechanism 320 is matched, one end of the lock block 300 sinks and leaves the blocking surface of the blocking and connecting part 210, which means that the lock block 300 avoids the blocking and connecting part 210 downwards, and the lock tongue 200 can reciprocate so that the lock head 230 leaves the lock hook 700 for unlocking;

in a locked state, when a key is required to unlock, the key is inserted and rotated, since the pick 510 is linked with the cylinder assembly 500, the pick 510 rotates along with the key, the rotated pick 510 lifts the lock block 300 upwards by utilizing the matching of the guide surface 511 and the guide block 310, the lock block 300 leaves the blocking surface of the blocking part 210, that is, the lock block 300 avoids the blocking part 210 upwards, and the lock tongue 200 can reciprocate so that the lock head 230 leaves the lock hook 700 to unlock.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only illustrative of the principles of the present invention, and that simple modifications and substitutions by those skilled in the art are within the scope of the present invention without departing from the spirit and scope of the present invention.
