[0028] Please see Figures 1-5 This utility model provides a technical solution: an adjustable smart door lock adapted to old doors, including a smart door lock body 1. A first panel 2 is provided on one side of the smart door lock body 1, and a second panel 3 is provided on the other side. Slots 4 are provided around one side of the first panel 2 and around one side of the second panel 3. A first decorative plate 5 is engaged with the outer side of one slot 4, and a second decorative plate 6 is engaged with the outer side of the other slot 4. A sleeve post 9 is installed at the top of the smart door lock body 1. A height-adjusting post 10 is slidably connected to the inner side of the sleeve post 9. A stop plate 11 is installed at the top of the height-adjusting post 10. A height-adjusting mechanism 13 for adjusting the height of the height-adjusting post 10 is provided inside the sleeve post 9. 1. Provides core intelligent unlocking functions to meet the needs of upgrading old doors to intelligent security; the first panel 2 and the second panel 3 cover both sides of the door body respectively, protecting the internal structure of the door lock and improving the integrity of the appearance; the slots 4 around the panel engage with the first decorative panel 5 and the second decorative panel 6, which can cover the gaps or scratches left after the old door body is installed, improving the aesthetic compatibility between the door lock and the door body; the sleeve 9 at the top of the intelligent door lock body 1 slides and engages with the height-increasing column 10 to adjust the height of the abutment plate 11, so that the abutment plate 11 can adapt to the top of old door bodies of different thicknesses or deformations, preventing the door lock from becoming loose after installation; the height adjustment mechanism 13 precisely controls the height of the height-increasing column 10 to ensure that the abutment plate 11 fits tightly against the door body, enhancing the stability of the door lock installation.

[0029] The height adjustment mechanism 13 includes a threaded rod 1301. The bottom end of the height-increasing column 10 has a threaded hole 1001. The inner side of the threaded hole 1001 and the outer side of the threaded rod 1301 engage. By engaging the threaded rod 1301 in the height adjustment mechanism 13 with the threaded hole 1001 at the bottom end of the height-increasing column 10, the rotation of the threaded rod 1301 can drive the height-increasing column 10 to move up and down along the inner side of the sleeve column 9, thereby achieving fine adjustment of the height of the support plate 11.

[0030] The outer bottom end of the threaded rod 1301 is rotatably connected to a retainer 1302. The two ends of the retainer 1302 are fixedly connected to the inner sides of the sleeve 9. The outer bottom end of the threaded rod 1301 is fixed by the retainer 1302, which restricts the threaded rod 1301 to rotate only along its own axis, so as to avoid it from deviating or tilting when rotating.

[0031] The inner side of the sleeve 9 is rotatably connected to an adjusting rod 1303. The bottom end of the threaded rod 1301 and the outer side of the adjusting rod 1303 are both fitted with bevel gears 1304. The adjusting rod 1303 and the threaded rod 1301 are engaged by the bevel gears 1304. By engaging the adjusting rod 1303 on the inner side of the sleeve 9 with the bevel gears 1304 on the outer side of the threaded rod 1301, the horizontal rotational power of the adjusting rod 1303 is converted into the vertical rotational power of the threaded rod 1301, changing the direction of power transmission. This allows the adjusting knob 1305 to be installed on the outer side of the panel, making it convenient for operators to adjust the height of the stop plate 11 from the surface of the door.

[0032] The second panel 3 has an adjustment knob 1305 on the side away from the first panel 2. One end of the adjustment knob 1305 is connected to one end of the adjustment rod 1303. The adjustment rod 1303 is connected to the adjustment knob 1305 on the outside of the second panel 3, providing the operator with a convenient point of force application. The adjustment rod 1303 can be manually rotated without removing the door lock, thereby adjusting the height of the backing plate 11.

[0033] The first decorative panel 5 has four threaded seats 7 installed on the side close to the second decorative panel 6, and the second decorative panel 6 has four locking bolts 8 installed on the side away from the first decorative panel 5. One end of the locking bolt 8 engages with the inner side of the threaded seat 7. By engaging the threaded seat 7 on the side of the first decorative panel 5 with the locking bolt 8 on the outer side of the second decorative panel 6, the first decorative panel 5, the door body and the second decorative panel 6 are tightly fixed, enhancing the connection strength between the door lock and the door body.

[0034] The top of the abutment plate 11 is equipped with several anti-slip blocks 12. The anti-slip blocks 12 at the top of the abutment plate 11 increase the friction between the abutment plate 11 and the top of the door, preventing the abutment plate 11 from sliding relative to the door due to vibration of the door opening and closing after the door lock is installed, and further enhancing the overall stability of the door lock.

[0035] Specifically, the working principle of this adjustable smart door lock adapted to old doors is as follows: During use, the smart lock body 1 provides the core smart unlocking function, meeting the needs of upgrading old doors to smart security; the first panel 2 and the second panel 3 cover both sides of the door, protecting the internal structure of the lock and improving its appearance; the slots 4 around the panels engage with the first decorative panel 5 and the second decorative panel 6, concealing any gaps or scratches left after installation on the old door, improving the aesthetic compatibility of the lock with the door; the sliding engagement of the sleeve post 9 at the top of the smart lock body 1 with the heightening post 10 adjusts the height of the stop plate 11, allowing... The abutment plate 11 can adapt to the top of old doors of different thicknesses or deformations, preventing the door lock from becoming loose after installation. The height of the lifter post 10 is precisely controlled by the height adjustment mechanism 13, ensuring that the abutment plate 11 fits tightly against the door body and enhancing the stability of the door lock installation. The threaded rod 1301 in the height adjustment mechanism 13 engages with the threaded hole 1001 at the bottom of the lifter post 10. The rotation of the threaded rod 1301 drives the lifter post 10 to move up and down along the inner side of the sleeve post 9, achieving fine adjustment of the height of the abutment plate 11. The outer bottom end of the threaded rod 1301 is fixed by the retainer 1302, restricting the threaded rod 1301 to rotate only along its own axis, preventing it from rotating. The offset or tilt is achieved by the engagement of the adjusting rod 1303 on the inner side of the sleeve 9 with the bevel gear 1304 on the outer side of the threaded rod 1301. This converts the horizontal rotational power of the adjusting rod 1303 into the vertical rotational power of the threaded rod 1301, changing the direction of power transmission. This allows the adjusting knob 1305 to be installed on the outer side of the panel, facilitating the operator to adjust the height of the stop plate 11 from the door surface. The adjusting knob 1305 on the outer side of the second panel 3 connects to the adjusting rod 1303, providing a convenient point of force application for the operator. The adjusting rod 1303 can be manually rotated without disassembling the door lock, thereby adjusting the height of the stop plate 11. This is achieved through the first decorative plate 5. The threaded seat 7 on one side engages with the locking bolt 8 on the outer side of the second decorative plate 6, tightly fixing the first decorative plate 5, the door body, and the second decorative plate 6, thereby enhancing the overall connection strength between the door lock and the door body. Through several anti-slip blocks 12 at the top of the abutment plate 11, the friction between the abutment plate 11 and the top of the door body is increased, preventing the abutment plate 11 from sliding relative to the door body due to vibrations from opening and closing the door body after the door lock is installed, further enhancing the overall stability of the door lock. This utility model can effectively realize the size adaptation, appearance modification, and stable installation of smart door locks for old door bodies without the need for large-scale renovation of old door bodies, reducing upgrade costs and having high practical value.
