[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-5 , a suitable password padlock cam, including a lower cover 1, an upper cover 2, a lock beam 3 and an adjustment component, the lower cover 1 and the upper cover 2 are enclosed to form a shell, an adjustment cavity for carrying the adjustment component is provided in the shell, the lock beam 3 is U-shaped with one end long and the other end short, the longer free end of the lock beam 3 is provided with several groups of protrusions 4 located on the same horizontal line, the adjustment component is provided in the adjustment cavity, the adjustment component includes a password wheel 5, a cam 6, a guide block 7, a spring 8 and a gasket 9, several groups of password wheels 5 are rotatably provided on the shell, the shell A through hole is provided on the top that is adapted to the password wheel 5. The cam 6 is provided in each group of the password wheels 5. The inner side of the cam 6 is provided with a slide groove that is adapted to the protrusion 4. The password wheel 5 is also provided with several groups of card slots. The outer side of the cam 6 is also provided with a card block 10 that is adapted to the card slot. A spring 8 is provided in the adjustment cavity. The two ends of the spring 8 are respectively connected to the bottom wall of the adjustment cavity and the gasket 9. A group of the cams 6 is in contact with the gasket 9. The housing is also provided with a lock hole that is adapted to the shorter free end of the lock beam 3;

[0024] The lower cover 1 and the upper cover 2 are closed to cover the adjustment component, and the end of the lock beam 3 with the protrusion 4 is inserted into the adjustment cavity. Initially, the spring 8 is in an extended state, and the card blocks 10 of several groups of cams 6 are inserted into the card slots of the corresponding password wheels 5. The password wheel 5 is rotated, and the password wheel 5 drives the cam 6 to rotate, so that the slide groove of the cam 6 is misaligned with the protrusion 4 of the lock beam 3, thereby achieving the locking function. When all the password wheels 5 are rotated to the correct password set, the slide grooves of all the cams 6 are aligned with the protrusion 4 of the lock beam 3. Pull the lock beam 3, and the lock beam 3 can be pulled upward out of the lock shell, thereby achieving the unlocking function. When the lock beam 3 is unlocked, rotate The lock beam 3 is moved to the 90° lock shell notch position, the lock beam 3 is pressed down, and rotated to the 180° position, and then the password wheel 5 is rotated. At this time, the cam 6 does not rotate with the password wheel 5, so that the password wheel 5 is moved to the password position to be set to realize the password change. When the lock beam 3 is no longer pressed down, the card block 10 is provided with a chamfer 11 at one end away from the spring 8, and the spring 8 pushes the gasket 9, and then the card blocks 10 of several groups of cams 6 are inserted into the corresponding card slots of the password wheel 5 under the action of the chamfer 11, which can play a guiding role, greatly reducing the probability of the password wheel 5 not being able to rotate and garbled codes due to code change, thereby improving the quality of the product.

[0025] During actual use, it is necessary to prevent the password wheel 5 from rotating without external force. To this end, the password wheel 5 is further provided with several groups of limit grooves, and the bottom wall of the adjustment cavity is further provided with a guide column 12. The adjustment cavity is further provided with a limit member that is engaged with the limit groove. The limit member includes a base plate 13 and a fin 14. The base plate 13 is provided with a guide hole that is adapted to the guide column 12. The base plate 13 is further provided with several groups of fins 14 that fit with the corresponding limit grooves. The limit member is elastic, and the limit groove is arc-shaped. When the limit groove is aligned with the corresponding fin 14, the elastic fin 14 presses against the limit groove to prevent the password wheel 5 from rotating at will. The fin 14 is connected to the base plate 13, and the base plate 13 is plugged into the guide column 12, so as to ensure the stability and convenience of equipment assembly.
