Multiple dustproof brushes 203 are distributed at one end of the protective frame 201. A sealing gasket 204 is installed on the outside of the adjustable combination dials 205, and the sealing gasket 204 is disposed on the mechanical combination lock body 101.

[0025] In this embodiment, the sealing gasket 204 is placed on the outside of the adjustable keypad 205 to provide a sealing effect and prevent dust from directly entering the interior of the adjustable keypad 205. The protective frame 201 provides protection for the adjustable keypad 205. The movable protective frame 201 moves inside the slide groove 202, making it easy to move the protective frame 201 to one side when unlocking. The dust brush 203 is distributed on one side of the protective frame 201, which helps to reduce the entry of dust and other particles into the interior of the adjustable keypad 205, reducing the impact of dust on the internal mechanical parts of the adjustable keypad 205, thereby reducing maintenance and repair costs, extending the service life of the adjustable keypad 205, and reducing the occurrence of jamming and other phenomena in the adjustable keypad 205, improving the smoothness of unlocking and adjusting the keypad.

[0026] Example 2: As Figures 1-6 As shown, the anti-peeping component 3 includes a mounting frame 301, which is sleeved on the outside of the adjustable combination dial 205 and connected to the mechanical combination lock body 101. A rotating shaft 302 is symmetrically mounted on the inner side of the mounting frame 301, and an anti-peeping baffle 303 is connected to the outer side of the rotating shaft 302. A torsion spring shaft 304 is connected to the bottom of the anti-peeping baffle 303, and both ends of the torsion spring shaft 304 are connected to the mounting frame 301. A handle 102 is mounted on the side of the mechanical combination lock body 101, and a lock tongue 103 is mounted on the side of the mechanical combination lock body 101.

[0027] In this embodiment, when unlocking, the movable protective frame 201 moves in the slide groove 202 and rotates using the rotating shaft 302. This, in conjunction with the torsion spring shaft 304, pushes the anti-peeping baffle 303, causing it to flip upwards. This provides a shielding and anti-peeping function for the adjustable combination lock 205, effectively protecting password privacy and preventing password leakage. This ensures the security and reliability of the mechanical combination lock assembly 1. After unlocking, when the movable protective frame 201 protects the adjustable combination lock 205, the anti-peeping baffle 303 is manually pushed inwards, causing it to flip downwards. Simultaneously, the movable protective frame 201 moves and blocks the outside of the anti-peeping baffle 303, facilitating its storage.
