The item can be connected through the arc-shaped locking rod 20, which facilitates the subsequent locking of the item by the device; then the right end of the locking rod 20 is manually pressed into the lock body shell 1. At the same time, the right end of the locking rod 20 will drive the moving rod 18 to slide between the two sets of limit rods 17. At this time, the moving rod 18 will compress the second spring 19;

[0032] The lock body 1 is provided with a first gear 4 fixedly mounted on the outside of the connecting rod 14 and the first rotating rod 3, and a code wheel body 5 is also fixedly mounted on the outside of the connecting rod 14 and the first rotating rod 3, and three groups of the first gear 4 and the code wheel body 5 are provided, and each group of the first gear 4 is located below the corresponding code wheel body 5; a second fixed rod 8 is fixedly mounted on the inside of the lock body shell 1, and three groups of the second fixed rod 8 are provided, and a second rotating rod 7 is rotatably mounted between the lock body shell 1 and the second fixed rod 8, and a second gear 6 and a limit wheel 9 are fixedly mounted on the outside of the second rotating rod 7; the code wheel body 5 is a regular decagonal structure when viewed in cross-section, and the code wheel body 5 is a structure that penetrates the lock body.

[0033] When the lock rod 20 is fully inserted into the lock body shell 1, the code wheel body 5 can be manually rotated at this time. The rotation of the code wheel body 5 will drive the connecting rod 14 and the first rotating rod 3 to rotate between the lock body shell 1 and the first fixed rod 2. The rotation of the connecting rod 14 and the first rotating rod 3 will drive the first gear 4 to rotate. The rotation of the first gear 4 will drive the second gear 6 to rotate through meshing.

Then manually rotate the lock rod 20 counterclockwise to facilitate the disengagement of the locked object. The lock rod 20 will drive the fourth gear 21 to rotate. The rotation of the fourth gear 21 will drive the rack 16 to move through the meshing connection. The movement of the rack 16 will drive the third gear 15 to rotate through the meshing connection. The rotation of the third gear 15 will drive the connecting rod 14 to rotate. The rotation of the connecting rod 14 will drive a set of code wheel bodies 5 to rotate, thereby allowing the code of a set of code wheel bodies 5 to be self-disrupted, thereby making the security of the device better.

[0037] A through hole for inserting the lock rod 20 is provided at the upper end of the lock body shell 1, and a snap-fit ​​groove corresponding to the slide rod 11 is provided at the right end of the lock body shell 1.

A sealing strip is provided at the connection between the lock body shell 1 and the password wheel body 5, and a sealing strip is also provided at the connection between the lock body shell 1 and the locking rod 20 to prevent leakage of lubricating oil.

[0039] The working principle of this embodiment is as follows: when using the unlocking self-disrupting security code wheel device, when it is necessary to use the device to lock other items, first, pull out the lock rod 20 to facilitate the subsequent locking of the item by the device; then press the right end of the lock rod 20 into the lock body shell 1, and then rotate the code wheel body 5. The code wheel body 5 drives the first gear 4 to rotate through the connecting rod 14 and the first rotating rod 3. The first gear 4 drives the second rotating rod 7 to rotate through the second gear 6. The second rotating rod 7 drives the limiting wheel 9 to make the limiting block 10 disengage from the limiting groove provided thereon, so that the limiting block 10 drives the sliding rod 11 to slide to the right. The rod 11 will be engaged with the locking rod 20 under the action of the first spring 12, so that the position of the locking rod 20 is limited, and then the use of the device is completed;

[0040] When the device needs to be unlocked, the code wheel body 5 is rotated in sequence according to the code set in the device, and the above steps are repeated. When the limit grooves on the three sets of limit wheels 9 are aligned with the limit blocks 10, the limit blocks 10 will be engaged with the limit wheels 9, and at the same time, the slide bar 11 will move to the left, so that its upper end will be separated from the lock bar 20, thereby facilitating the rapid unlocking of the device.

[0041] Pull the right end of the locking rod 20 out of the lock body housing 1, so that the fourth gear 21 is engaged and connected to the rack 16, and then rotate the locking rod 20 counterclockwise. The locking rod 20 drives the rack 16 to move through the fourth gear 21, and the rack 16 drives the connecting rod 14 to rotate through the third gear 15. The connecting rod 14 will drive a group of code wheel bodies 5 to rotate, thereby allowing the code of a group of code wheel bodies 5 to be self-scrambled, thereby making the security of the device better; thus completing a series of tasks.
