When unlocking, the first connecting rod 4 is not limited, and the first connecting rod 4 rotates under the spring force of the first spring 5 . The first inclined block pushes the second inclined block, so that the second connecting rod 6 is retracted, the second spring 7 is compressed, and the first end of the second connecting rod 6 exits the limiting groove.

Preferably, the combination lock assembly includes several combination disk assemblies. The cipher disk assembly all comprises cipher disk 8, cipher disk limit block 9, cipher disk limit block spring 10. The code disk 8 is arranged on the code disk limit block 9, and the code disk 8 and the code disk limit block 9 rotate coaxially. A card slot is provided on the side wall of each code disc limit block 9 . The first end of the code disk limit block spring 10 is connected with the code disk limit block 9, and the second end of the code disk limit block spring 10 is connected with the ring-shaped locking portion accommodating cavity. The first connecting rod 4 is provided with a plurality of limit rods relative to each code disc limit block 9 . Each limit rod is provided with a block corresponding to the slot. Each cipher disk 8 is provided with a protrusion on the face connected to the cipher disk limit block 9, and each cipher disk limit block 9 is provided with some grooves corresponding to the protrusion, each groove Corresponding to the numbers on the combination disk 8 respectively, the combination disk 8 locks the relative position through the grooves on the combination disk limit block 9 through the protrusions.

Further, the combination lock assembly also includes a combination reset link 11 . The password reset connecting rod 11 is sleeved on each password disc limit block 9 for password reset. To reset the password, the operation needs to be performed under the state that the password is correct. When the code is correct, the notch on each code disk 8 corresponds to the protrusion of the reset code connecting rod, and the reset code connecting rod is pulled to make the code disk limit block 9 break away from the small axis, and the code is reset under the action of the spring. The disk limiter 9 pops up, and the groove of the code disk limit block 9 is separated from the protrusion of the code disk 8. At this time, turn the code disk 8 to the desired position, and then dial back to reset the code connecting rod. At this time, the code disk The limit block 9 is pressed down so that the code disk limit block 9 and the code disk 8 are locked, and the password correction is completed.

Preferably, a customs lock 12 and a customs lock connecting rod 13 are also included. The customs lock connecting rod 13 is an arc-shaped connecting rod, and the customs lock connecting rod 13 is arranged in the accommodating cavity of the annular locking part. The customs lock 12 is arranged in the accommodating cavity of the annular locking part, and the output end of the customs lock 12 is connected with the first end of the customs lock connecting rod 13 . The second end of the customs lock connecting rod 13 is provided with a third slanting block, and the third slanting block is connected with the second slanting block.

Further, the top shell 2 is provided with a display port for displaying the password disc 8 . The user who opens the display port can understand the characters shown in the password disk 8 more clearly.

The working principle of the circular lock is further elaborated as follows:

When the password is correct, the position of the combination disc limit block 9 is correct, and the draw-in groove on each combination disc limit block 9 is corresponding to the block on the first connecting rod 4, and the first connecting rod 4 is positioned on the first spring 5. The active force is retracted state, the first slanting block at the first end of the first connecting rod 4 presses the second slanting block of the second connecting rod 6, and drives the second connecting rod 6 to move, so that the first slanting block of the second connecting rod 6 One end withdraws from the limit groove on the rotating ring 3, so that the rotating ring 3 is in an unlocked state, and the rotating ring 3 is rotated so that the locking rod on it withdraws from the locking hole, and the lock to the locking hook 14 is released.

When the combination disk 8 is moved, any slot of the combination disk 8 does not correspond to the block on the first connecting rod 4, so that the first connecting rod 4 slides out, the first oblique block no longer presses the second oblique block, and the second oblique block no longer presses the second oblique block. The two connecting rods 6 are released under the action of the second spring 7. When the user closes the lock, the rotating ring 3 is rotated so that the locking rod is inserted into the locking hole of the lock hook 14. When inserted, the limit groove on the rotating ring 3 rotates to At the position corresponding to the second connecting rod 6, the second connecting rod 6 enters the limiting groove, and the lock takes effect.

When the customs needs to unlock, the lockset is in a locked state, and the password is not known, so the first connecting rod 4 cannot return to its original position. Turn the 12 cores of the customs lock, the 12 cores of the customs lock drive the rotation of the customs lock connecting rod 13, and the third inclined block at the other end of the customs lock connecting rod 13 pushes the second connecting rod 6 to retract by pressing the second inclined block, that is, the locked state is released. When the customs officer finishes checking, turn back the customs lock 12 cores, the customs lock connecting rod 13 returns, the second connecting rod 6 pops up, and then locks, the password does not change and can be unlocked by the customs lock 12 cores.

Embodiment two
