A dust-adhesive cotton 43 is fixedly connected to the lower surface of the partition 42. A bump 44 is fixedly connected to the upper surface of the partition 42. An arc plate 45 for knocking the bump 44 is slidably connected to the inner wall at the front above the slider 41 through an elastic member.

[0034] The side of the arc plate 45 close to the partition 42 is in contact with the surface of the protrusion 44, the rear part of the slider 41 is slidably connected to the inner wall of the lock body 2 through a spring, the two sides of the slider 41 are in contact with the inner wall of the cover plate 3, and the surface of the dust-sticking cotton 43 is in contact with the surface of the fingerprint scanner.

[0035] The inner wall of the lock body 2 is provided with a locking limit device 5 for limiting the handle 6. The locking limit device 5 includes a rotating shaft 51. A T-shaped limit slot 52 is opened on the surface of the rotating shaft 51. The inner wall of the limit slot 52 is slidably connected with a limit rod 53 for locking the rotating shaft 51.

[0036] The side of the limiting rod 53 away from the limiting slot 52 is in contact with the right side of the slider 41, and the inner walls of the two contact surfaces are fixedly connected with magnets, so that the limiting rod 53 and the slider 41 are attracted and fixedly connected by the magnets.

[0038] The front part of the push block 74 contacts the rear part of the fixing rod 71, the side of the fixing rod 71 away from the push block 74 is fixedly connected to the side of the connecting plate 7 close to the lock body 2, the upper surface of the fixing rod 71 contacts the lower surface of the slider 41, and the surfaces of the left contact 72 and the right contact 73 are both connected to the inner wall of the lock body 2 by screws.

[0039] Working principle: when unlocking is required, the cover plate 3 is pushed downward to make the connecting rod on the connecting plate 7 slide in the slide groove 8. When the connecting rod moves to the top of the slide groove 8, the cover plate 3 is rotated to make the rear surface of the cover plate 3 face the front. The buttons and fingerprint scanner are both behind the cover plate 3. Therefore, this arrangement can prevent children from pushing down the cover plate 3 and then using the buttons and scanner, which increases the concealment of the buttons and scanner and has a certain anti-theft effect.

[0040] After unlocking, the cover plate 3 is rotated and slid to reset, and the magnets 1 9 and 2 10 are adsorbed and fixed. At the same time, the slider 41 is extended into the fingerprint scanner under the action of the spring, and the dust on the surface of the fingerprint scanner is adhered by the dust-sticking cotton 43 to prevent the fingerprint scanning from being affected when it is used next time. When the slider 41 is extended into the fingerprint scanner, the movement of the slider 41 drives the limit rod 53 to move together through the magnet, so that the limit rod 53 is inserted into the vertical groove of the limit slot 52, thereby limiting and locking the rotating shaft 51. Therefore, the handle 6 cannot be rotated when the cover plate 3 is closed. When the cover plate 3 is opened and the slider 41 is retracted, the limit rod 52 moves out of the vertical groove of the limit slot 52 and then into the annular groove. At this time, the handle 6 can drive the rotating shaft 51 to rotate;

[0041] When the cover plate 3 is opened and rotated, the front part of the cover plate 3 will contact the arc plate 45 on the slider 41, thereby pushing the arc plate 45 to move, and the arc plate 45 will collide with the protrusion 44, thereby driving the partition plate 42 to vibrate, thereby causing the dust on the sticky cotton 43 to fall off, thereby achieving self-cleaning of the sticky cotton 43;

[0042] When a thief tries to pry the lock, the cover plate 3 and the connecting plate 7 will be pried off, and the falling of the connecting plate 7 will drive the fixing rod 71 to fall together. At this time, the push block 74 will no longer be limited by the fixing rod 71. At this time, the slider 41 will pop out under the action of the spring. At this time, the left contact 72 and the right contact 73 are no longer blocked by the slider 41, and then the alarm device will be energized to sound an alarm, thereby preventing the thief from continuing to commit crimes.

[0043] The present invention provides a security fingerprint password door lock. There are many methods and ways to implement the technical solution. The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention. All components not specified in this embodiment can be implemented by existing technologies.
