[0030] A door lock with a keyhole protection mechanism, such as Figure 1-Figure 3As shown, it includes a door lock panel 10 and a door handle 30 installed on the door lock panel 10, and a sliding protective cover 20 is installed on the top of the door lock panel 10; a storage groove 12 matched with the size of the sliding protective cover 20 is opened on the top of the side of the door lock panel 10 close to the door handle 30, and a lock hole 40 is arranged at the center of the surface of the storage groove 12, and parallel adjustment slide grooves 13 are symmetrically arranged on both sides of the lock hole 40; an auxiliary lighting strip 22 is embedded in the center of the bottom surface of the sliding protective cover 20, and an adjustment slide seat 23 is arranged on the side of the sliding protective cover 20 that contacts the storage groove 12, and the cross-sectional size of the adjustment slide seat 23 is matched with that of the adjustment slide groove 13 and both are convex-shaped. By setting the sliding protective cover 20, effective protection of the lock hole 40 can be achieved. When the lock hole is not needed, the sliding protective cover 20 can slide into the storage groove 12, covering the lock hole 40, preventing dust, moisture or other impurities from entering the lock hole, thereby ensuring the normal use of the door lock and extending the service life of the door lock. The auxiliary lighting strip 22 embedded in the center of the bottom surface of the sliding protective cover 20 can provide lighting at night or in a dark environment, which is convenient for users to find the lock hole and unlock it smoothly. The design of the storage groove 12 not only provides storage space for the sliding protective cover 20, but also makes the appearance of the door lock panel 10 more neat and beautiful. The coordinated use of the adjustment slide groove 13 and the adjustment slide seat 23 realizes the smooth sliding of the sliding protective cover 20 in the storage groove 12. This convex cross-sectional design not only ensures the smoothness of sliding, but also increases the stability of sliding, preventing the sliding protective cover from offsetting or shaking during the sliding process.

[0031] Furthermore, the surface pattern of the sliding protection cover 20 is the same in shape and color as the surface pattern of the door lock panel 10, so that the sliding protection cover 20 is perfectly integrated with the door lock panel 10 in the closed state, which is more visually unified and harmonious, and improves the overall aesthetics of the door lock.

[0032] Specifically, a magnetic strip 14 is provided on the bottom surface of the storage slot 12, and the bottom edge of the sliding protective cover 20 is made of a magnet ring. The bottom of the sliding protective cover 20 is magnetically connected to the magnetic strip 14, and the stable closure of the sliding protective cover 20 is achieved by magnetic connection.
