DETAILED DESCRIPTION

[0019] 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.

[0020] See also Figure 1-3 , the utility model provides a technical solution:

[0021] In this technical solution, a dustproof panel of a handle lock includes a panel body 1 and a handle 2. The handle 2 is inserted into the side wall of the panel body 1 and can rotate on the panel body 1. A recess 3 is provided on the side wall of the handle 2. A fingerprint sensor 4 is installed in the recess 3. The fingerprint sensor 4 is electrically connected to the external smart lock core.

[0022] The inner wall of the give way groove 3 is provided with a slide groove 5, and a shielding plate 6 is slidably installed in the slide groove 5. The shielding plate 6 can shield the fingerprint sensor 4. The side wall of the handle 2 is provided with a mounting groove 7, and a clamping block 8 is slidably installed in the mounting groove 7. One end of a connecting rope 9 is installed on the inner wall of the mounting groove 7, and the other end of the connecting rope 9 passes through the side wall of the slide groove 5 and is connected to the side wall of the shielding plate 6. One end of a spring 10 is installed on the side wall of the shielding plate 6, and the other end of the spring 10 is in contact with the inner wall of the slide groove 5;

[0023] In this technical solution, the panel body 1 is installed in the lock slot on the outer door panel by fasteners such as screws. When unlocking the door lock, the clamping block 8 in the installation slot 7 can be pressed inward to suppress the connecting rope 9, thereby driving the shielding plate 6 to retract into the sliding slot 5 through the connecting rope 9, so that the fingerprint sensor 4 is exposed. At this time, people can press their fingers on the fingerprint sensor 4 to unlock the lock with their fingerprints.

[0024] After unlocking, the person's hand leaves the handle 2. At this time, under the action of the spring 10, the shielding plate 6 will slide to the outside of the slide groove 5, thereby blocking the clearance groove 3 and shielding the fingerprint sensor 4 to prevent the fingerprint sensor 4 from being contaminated by external dust. This process is completed automatically under the action of the spring 10, so the shielding plate 6 will not be forgotten and not reset.

[0025] The fingerprint sensor 4 and smart lock core proposed in this article are both existing technologies, so the specific structure and working principle of these components will not be described in detail.

[0026] In some technical solutions, a card slot 11 is provided on the side wall of the clamping block 8, and a card block 12 is installed on the inner wall of the mounting groove 7. The card block 12 can engage with the card slot 11. A through hole 13 is provided on the side wall of the mounting groove 7, and the other end of the through hole 13 passes through the side wall of the slide groove 5. The connecting rope 9 is inserted into the slide groove 5 through the through hole 13.

[0027] In this technical solution, the engagement of the card block 12 with the card slot 11 can increase the length of the connecting rope 9, enabling it to move the shielding plate 6 a longer distance, thereby fully exposing the fingerprint sensor 4 and avoiding affecting the fingerprint sensor 4's fingerprint collection.

[0028] Herein, the side walls of the clamping slot 11 and the clamping slot 12 are both arc-shaped to avoid damage to the connecting rope 9 and affecting the pulling of the shielding plate 6.

[0029] In some technical solutions, positioning sleeves 14 are installed on the inner walls of the baffle 6 and the slide 5, the spring 10 is sleeved on the outside of the positioning sleeve 14, and the connecting rope 9 is inserted into the positioning sleeve 14 and connected to the side wall of the baffle 6.

[0030] In this technical solution, the positioning sleeve 14 is provided to prevent the spring 10 from being displaced, thereby preventing the shielding plate 6 from being reset.

[0031] In some technical solutions, a rubber plate 15 is mounted on the side wall of the shielding plate 6 . The cross section of the rubber plate 15 is arc-shaped, and the rubber plate 15 can fit the inner wall of the clearance groove 3 .

[0032] In this technical solution, the provision of the rubber plate 15 can improve the sealing performance between the shielding plate 6 and the clearance groove 3 when the shielding plate 6 is closed.

[0033] In some technical solutions, a touch panel 16 is installed on the side wall of the panel body 1, and the touch panel 16 is electrically connected to the external smart lock core.

[0034] In this technical solution, the touch panel 16 is a prior art digital touch keyboard, which allows the smart lock cylinder to be unlocked by entering a password.

[0035] In some technical solutions, a sealing ring 17 is sleeved on the outer wall of the handle 2 , and the sealing ring 17 can fit with the side wall of the panel body 1 .

[0036] In this technical solution, the sealing ring 17 can seal the gap between the handle 2 and the panel body 1 to prevent the entry of external dust and other impurities, thereby preventing the rotation of the handle 2 from being affected.

[0037] Working Principle: The panel body 1 is installed in the lock slot on the outer door panel using screws and other fasteners. To unlock the door lock, the clamping block 8 in the installation slot 7 is pressed inward to suppress the connecting rope 9, which in turn drives the shielding plate 6 to retract into the slide slot 5 through the connecting rope 9, exposing the fingerprint sensor 4. At this time, people can press their finger on the fingerprint sensor 4 to unlock the lock with their fingerprint.

[0038] After unlocking, the person's hand leaves the handle 2. At this time, under the action of the spring 10, the shielding plate 6 will slide to the outside of the slide groove 5, thereby blocking the clearance groove 3, so that it blocks the fingerprint sensor 4 and prevents the fingerprint sensor 4 from being contaminated by external dust.
