A plurality of first magnet bodies 24 are installed on both the code changing wheel 22 and the magnet fixing wheel 23. A bearing 25 is also installed in the rotating wheel 21, and the bearing 25 is sleeved on the end of the magnet fixing wheel 23 away from the code changing wheel 22. The key chain assembly 3 includes a key chain connector 31, and the key chain connector 31 is clamped on the end of the alloy tail cover 16 away from the alloy outer cover 11. Second magnet bodies 34 are installed in the key chain connector 31 and the alloy tail cover 16, and the two second magnet bodies 34 attract each other. A keychain body 35 is provided at one end of the keychain connector 31 away from the alloy tail cover 16. Two inverted clips 32 are also installed in the keychain connector 31. A clip spring 33 is installed between the two inverted clips 32. Pressing blocks 36 and clips 37 are installed on the opposite backs of the two inverted clips 32.

The two clips 37 both penetrate the surface of the keychain connector 31 and are clipped in the alloy tail cover 16.

[0040] When using the device, firstly, the multiple rotating wheels 21 are rotated in sequence according to the preset password. When the rotating wheel 21 rotates, the code-changing wheel 22 in the rotating wheel 21 is driven to rotate at the same time. The code-changing wheel 22 drives the magnet fixing wheel 23 to rotate at the same time through the first magnet body 24, so that the lock holes of the code-changing wheel 22 and the magnet fixing wheel 23 on the multiple rotating wheels 21 are aligned. After alignment, the key rack 4 is inserted and rotated to unlock the lock;

[0041] Magnetic elements are used to replace traditional plastic sheets. The rotation and locking functions of the password wheel are achieved through magnetic adsorption and rotation. The setting of the magnetic structure can not only provide a smooth operating experience, but also avoid the wear caused by mechanical friction during long-term use. The rebound system is made of metal springs, which can effectively prevent the wear of the password wheel and ensure stable performance during long-term use.

[0042] For example 2, please refer to Figure 1-10 The alloy outer cover 11 and the alloy tail cover 16 are also provided with a protection component 5, which includes two protection sleeves 51, which are respectively installed on the alloy outer cover 11 and the alloy tail cover 16, and an arc-shaped protection cover 52 is installed between the two protection sleeves 51. A sliding cover 53 is also slidably connected between the two protection sleeves 51, and the sliding cover 53 is arranged at the opening of the arc-shaped protection cover 52. A sealing gasket is arranged at the joint of the sliding cover 53 and the arc-shaped protection cover 52. A moving part 55 is installed on one end of the sliding cover 53 close to the alloy outer cover 11, and the moving part 55 is installed on the sliding cover 53. A limiting plug block 56 is installed on the side of the moving member 55 close to the protective sleeve 51. Two limiting holes 54 are provided on the protective sleeve 51 for fixing the limiting plug block 56. A fixing cylinder 57 is also installed on the sliding cover 53. A limiting block 58 is slidably engaged in the fixing cylinder 57. A convex block is slidably arranged on the limiting block 58, and the convex block is slidably engaged on the limiting plug block 56. One end of the limiting block 58 away from the limiting plug block 56 is fixed to the moving member 55. A push rod 59 is also installed on the top of the sliding cover 53. The push rod 59 is slidably arranged in the adjacent protective sleeve 51.

[0043] The protective sleeve 51 and the arc-shaped protective cover 52 can protect the code wheel body 1 and the lock core assembly 2. At the same time, when unlocking is required, the moving member 55 is pulled to drive the limiting block 58 to be pulled out of the fixed tube 57, so that the limiting plug 56 on the moving member 55 is moved out of the limiting hole 54, and the moving member 55 is pushed to drive the sliding cover 53 to slide, so that the sliding cover 53 is separated from the arc-shaped protective cover 52, so that the opening of the arc-shaped protective cover 52 is exposed, so that the rotating wheel 21 is conveniently rotated to unlock;

[0044] When the moving member 55 drives the limiting plug 56 to slide to another limiting hole 54, the moving member 55 is pressed inward to retract the limiting block 58 into the fixed tube 57, so that the limiting plug 56 is engaged in the limiting hole 54, and the sliding cover 53 can be fixed. When the use is finished, the moving member 55 is pulled again to move the limiting block 58 out of the fixed tube 57, so that the limiting plug 56 is moved out of the limiting hole 54, and the moving member 55 drives the sliding cover 53 to move again to close the protective sleeve 51.

[0045] By providing the protective sleeve 51 and the arc-shaped protective cover 52, the code wheel body 1 and the lock core assembly 2 can be protected to enhance the overall durability.

[0046] For example 3, please refer to Figure 1-10 , the protective sleeve 51 in the alloy outer cover 11 is also rotatably connected with an adjusting disk 6, and two sealing plates 7 are slidably arranged in the adjusting disk 6, and the diameter of the two sealing plates 7 is larger than the diameter of the lock hole, and an abutting rod 61 is also installed at the bottom of the adjusting disk 6, and the abutting rod 61 abuts against the push rod 59 on the sliding cover 53, and two inclined grooves 62 are symmetrically provided in the adjusting disk 6, and one end of the two inclined grooves 62 is extended to have a straight groove 63, and two driving racks 64 are also installed in the adjusting disk 6, and the two driving racks 64 are respectively installed on one side of the adjacent straight grooves 63, and the two inclined grooves 62 are slidably connected with sliding shafts 65, and the tops of the two sliding shafts 65 are slidably connected to the inner wall of the top of the protective sleeve 51, and the two sliding shafts 65 are also rotatably connected with synchronous gears 66, wherein, The tops of the two synchronous gears 66 are hinged with connecting rods 67, and the other ends of the two connecting rods 67 respectively penetrate the adjacent sealing plates 7 and extend to the inside of the sealing plates 7. The two sliding shafts 65 are also equipped with connecting plates, and the other ends of the two connecting plates are respectively fixed to the bottoms of the adjacent sealing plates 7. A torsion spring is also sleeved on the outer wall of the adjusting disk 6, and one end of the torsion spring is fixed to the outer wall of the adjusting disk 6, and the other end is fixed to the inner wall of the top of the protective sleeve 51. The extension sections of the two connecting rods 67 are hinged with connecting blocks 68, and the connecting blocks 68 are slidably connected to the sealing plates 7. A rubber sealing strip 69 is also installed on the connecting blocks 68. The facing surfaces of the two sealing plates 7 are provided with connecting grooves 71, and the connecting grooves 71 are connected to the inside of the sealing plates 7. The two rubber sealing strips 69 are respectively slidably connected to the adjacent connecting grooves 71.

[0047] When the sliding cover 53 slides, the push rod 59 arranged on the sliding cover 53 pushes the abutment rod 61 at the same time, so that the abutment rod 61 drives the adjusting disk 6 to rotate. In the initial position, the two sealing plates 7 abut against each other to close the lock hole. The two sliding shafts 65 are located in the adjacent straight grooves 63. When the adjusting disk 6 rotates, the sliding shafts 65 in the adjusting disk 6 rotate along the straight grooves 63 to the inclined grooves 62. When the sliding shafts 65 move, the two sealing plates 7 are pulled open by the connecting plate at the same time to expose the lock hole. When the adjusting disk 6 rotates, the torsion spring on the adjusting disk 6 contracts and stores force.

[0048] When the sliding cover 53 is closed after use, the resilience of the torsion spring on the adjusting disk 6 drives the adjusting disk 6 to reverse and reset. When the adjusting disk 6 rotates, the two sliding shafts 65 slide from the inclined groove 62 toward the direction close to the straight groove 63, so that the two sealing plates 7 close the lock hole again.

[0049] When the sliding shaft 65 rotates to the straight groove 63, the synchronous gear 66 on the sliding shaft 65 meshes with the adjacent driving rack 64, and the driving rack 64 drives the synchronous gear 66 to rotate. When the synchronous gear 66 rotates, the connecting rod 67 on the synchronous gear 66 drives the connecting block 68 to move, so that the connecting block 68 drives the rubber sealing strip 69 to move toward the connecting groove 71. The two connecting grooves 71 are squeezed against each other, so that the connection between the two sealing plates 7 is closed, further enhancing the overall sealing performance;

[0050] By providing the arc-shaped protective cover 52, the sliding cover 53 and the sealing plate 7, the combination wheel body 1 and the lock core assembly 2 can be sealed to prevent the device from being eroded by rainwater when used outdoors, thereby improving the durability of the device. At the same time, the lock hole can be sealed by two sealing plates 7 to prevent foreign objects from clogging the lock hole and affecting normal use.

[0051] When using the device, firstly, the multiple rotating wheels 21 are rotated in sequence according to the preset password. When the rotating wheel 21 rotates, the code-changing wheel 22 in the rotating wheel 21 is driven to rotate at the same time. The code-changing wheel 22 drives the magnet fixing wheel 23 to rotate at the same time through the first magnet body 24, so that the lock holes of the code-changing wheel 22 and the magnet fixing wheel 23 on the multiple rotating wheels 21 are aligned. After alignment, the key rack 4 is inserted and rotated to unlock the lock;

[0052] Magnetic elements are used to replace traditional plastic sheets. The rotation and locking functions of the code wheel are achieved through magnetic adsorption and rotation. The setting of the magnetic structure can not only provide a smooth operating experience, but also avoid wear caused by mechanical friction during long-term use. The rebound system is made of metal springs, which can effectively prevent wear of the code wheel and ensure stable performance during long-term use.

[0053] The protective sleeve 51 and the arc-shaped protective cover 52 can protect the code wheel body 1 and the lock core assembly 2. At the same time, when unlocking is required, the moving member 55 is pulled to move the limiting plug 56 on the moving member 55 out of the limiting hole 54, and the moving member 55 is pushed to drive the sliding cover 53 to slide, so that the sliding cover 53 is separated from the arc-shaped protective cover 52, so that the opening of the arc-shaped protective cover 52 is exposed, and the rotating wheel 21 is conveniently rotated to unlock;

[0054] When the moving member 55 drives the limiting plug 56 to slide to another limiting hole 54, the moving member 55 is pressed inward to retract the limiting block 58 into the fixed tube 57, so that the limiting plug 56 is engaged in the limiting hole 54, and the sliding cover 53 can be fixed. When the use is finished, the moving member 55 is pulled again to move the limiting block 58 out of the fixed tube 57, so that the limiting plug 56 is moved out of the limiting hole 54, and the moving member 55 drives the sliding cover 53 to move again to close the protective sleeve 51.

[0055] When the sliding cover 53 slides, the push rod 59 provided on the sliding cover 53 pushes the abutment rod 61 at the same time, so that the abutment rod 61 drives the adjusting disk 6 to rotate, and the sliding shaft 65 in the adjusting disk 6 rotates along the straight groove 63 to the inclined groove 62. When the sliding shaft 65 moves, the two sealing plates 7 are pulled open by the connecting plate to expose the lock hole. When the adjusting disk 6 rotates, the torsion spring on the adjusting disk 6 contracts and stores force.

[0056] When the sliding cover 53 is closed after use, the resilience of the torsion spring on the adjusting disk 6 drives the adjusting disk 6 to reverse and reset. When the adjusting disk 6 rotates, the two sliding shafts 65 slide from the inclined groove 62 toward the direction close to the straight groove 63, so that the two sealing plates 7 close the lock hole again.

[0057] When the sliding shaft 65 rotates into the straight groove 63, the synchronous gear 66 on the sliding shaft 65 meshes with the adjacent driving rack 64, and the driving rack 64 pushes the synchronous gear 66 to rotate. When the synchronous gear 66 rotates, the connecting rod 67 on the synchronous gear 66 pushes the connecting block 68 to move, so that the connecting block 68 drives the rubber sealing strip 69 to move toward the connecting groove 71. The two connecting grooves 71 are squeezed against each other to close the connection between the two sealing plates 7, thereby further enhancing the overall sealing.

[0058] It should be noted that the various devices in this application are common devices in the market, and can be selected according to specific needs during specific use. The circuit connection relationship of each device belongs to a simple series and parallel connection circuit. There is no innovation in the circuit connection part. Those skilled in the art can implement it relatively easily. It belongs to the existing technology and will not be elaborated on.

[0059] The above are only preferred specific implementations of the present invention, but the protection scope of the present invention is not limited thereto.
