[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Figure 1-6As shown, this utility model provides a smart lock body linkage structure, including a housing 1, a cover plate 2 installed on the back of the housing 1 by screws, a touch screen 3 fixedly installed on the housing 1, a battery installed inside the housing 1 to power the touch screen 3 and motor 18, an unlocking password can be entered on the touch screen 3, the touch screen 3 is equipped with a fingerprint one-button lock switch, a sliding rod 10 is slidably installed inside the housing 1, a first latch 6 is fixedly installed at one end of the sliding rod 10, a slider 19 is slidably installed inside the housing 1, a second latch 7 is fixedly installed at one end of the slider 19, one side of the first latch 6 is set with an angle, the device can be installed on the entrance door, when installing the door lock, the angled side of the first latch 6 faces the inside, the entrance door closes from the outside to the inside, the inside of the housing 1 is fixedly installed A sleeve 11 is fixedly installed, and one end of a sliding rod 10 is slidably inserted into the sleeve 11. A spring 25 is fixedly installed inside the sleeve 11, and one end of the spring 25 is fixedly connected to one end of the sliding rod 10. A sliding plate 12 is slidably installed inside the housing 1, and the sliding rod 10 is inserted through the sliding plate 12. A first threaded rod 13 and a second threaded rod 14 are rotatably installed inside the housing 1, and the first threaded rod 13 and the second threaded rod 14 are respectively threaded into the bottom end of the sliding plate 12 and the top end of the slider 19. A first gear 15 and a second gear 16 are fixedly installed at one end of the first threaded rod 13 and the second threaded rod 14, respectively. A motor 18 is fixedly installed inside the housing 1, and a half gear 17 is fixedly installed at the output end of the motor 18. 7 engages with the first gear 15 and the second gear 16. When the owner enters the unlock password or unlocks by touching the fingerprint button, the motor 18 drives the half gear 17 to rotate (the half gear 17 cannot simultaneously engage with the first gear 15 and the second gear 16). The half gear 17 first drives the second gear 16 to rotate (the teeth on the half gear 17 can drive the first gear 15 and the second gear 16 to rotate, which is just enough to drive the first latch 6 and the second latch 7 to fully retract into the housing 1 or fully extend). The second gear 16 drives the second threaded rod 14 to rotate, and the second threaded rod 14 drives the slider 19 to slide. The slider 19 drives the second latch 7 to slide and retract into the housing 1. At this time, the half gear 17 disengages from the second gear 16, and then the motor 18 continues... The motor 18 drives the half-gear 17 to rotate, causing it to mesh with the first gear 15. The first gear 15 then drives the first threaded rod 13 to rotate, which in turn drives the sliding plate 12 to slide. The sliding plate 12 pushes the sliding rod 10 into the sleeve 11 and compresses the spring 25. The sliding rod 10 then causes the first latch 6 to retract into the housing 1, completing the unlocking process. (When locking from the outside, the homeowner can lock the door by touching the fingerprint button; the locking process is the reverse of the above steps.) This allows the entrance door to open. After opening, the motor 18 drives the half-gear 17 to reverse, which in turn drives the first gear 15 to reverse. The first gear 15 then drives the first threaded rod 13 to reverse, and the first threaded rod 13 resets the sliding plate 12. The spring 25 then returns to its original position.The sliding rod 10 pushes the first latch 6 out of the housing 1 and resets it. At this time, the motor 18 and the half-gear 17 stop working. Then, the entrance door is closed from the outside to the inside. Since the side of the first latch 6 facing the inside is set at an angle, when the first latch 6 touches the door frame, it is subjected to external force and retracts into the housing 1. The sliding rod 10 compresses the spring 25. When the entrance door is closed, the sliding rod 10 receives the rebound force of the spring 25, pushing the first latch 6 out and inserting it into the corresponding lock groove on the door frame, thereby closing the entrance door.

[0021] A key plug 4 is rotatably mounted on the housing 1. A third bevel gear 29 is fixedly mounted on one end of the key plug 4. A knob 9 is rotatably mounted inside the housing 1. A second bevel gear 28 is fixedly mounted on one end of the knob 9. A first bevel gear 27 is fixedly mounted on one end of the shaft of the half-gear 17, and the first bevel gear 27 meshes with the second bevel gear 28 and the third bevel gear 29. When the touch screen 3 is malfunctioning but still usable, a mechanical key can be inserted into the key plug 4 to drive the key plug 4 to rotate the third bevel gear 29, which in turn drives the first bevel gear 29. When the first bevel gear 27 rotates, it drives the half gear 17 to rotate (the motor 18 does not have a self-locking function, that is, it can still be driven to rotate by external force when it is stopped). In conjunction with other transmission components, it realizes unlocking and locking. After the door is closed inside, the knob 9 can be rotated. The knob 9 drives the second bevel gear 28 to rotate, the second bevel gear 28 drives the first bevel gear 27 to rotate, and the first bevel gear 27 drives the half gear 17 to rotate. In conjunction with other transmission components, it drives the second lock tongue 7 to extend out from the housing 1 and insert into the corresponding lock groove on the door frame to realize anti-locking.

[0022] A toothed groove 26 is provided in the cavity of the sliding rod 10. A toothed rod 20 is rotatably installed inside the housing 1, and the toothed rod 20 meshes with the toothed groove 26 in the sliding rod 10. An internal hexagonal plug 21 is fixedly installed at one end of the toothed rod 20. A second handle 8 is rotatably installed on the cover plate 2. A large gear 22 is fixedly installed at one end of the second handle 8. A small gear 23 is rotatably installed on the cover plate 2, and the small gear 23 meshes with the large gear 22. An internal hexagonal socket 24 is fixedly installed on the small gear 23, and the internal hexagonal socket 24 can be fitted onto the internal hexagonal plug 21. By removing the cover plate 2, it is convenient to maintain and replace the parts inside the housing 1. After the cover plate 2 is installed, the internal hexagonal socket 24 on the small gear 23 can be fitted onto the internal hexagonal socket 21 on the toothed rod 20. On plug 21, when the second latch 7 is not extended, the second handle 8 can drive the large gear 22 to rotate indoors (by setting the large gear 22 and the small gear 23, the second handle 8 can rotate within a range of about 90 degrees, which is just enough to drive the first latch 6 to fully retract into the housing 1 or fully extend). The large gear 22 drives the small gear 23 to rotate, and the small gear 23 drives the rack 20 to rotate. The rack 20 engages with the tooth groove 26 in the sliding rod 10, causing the sliding rod 10 to insert into the sleeve 11 and compress the spring 25. The sliding rod 10 drives the first latch 6 to retract into the housing 1. When the second handle 8 is released, the spring force of the spring 25 is used to reset the first latch 6 and insert it into the corresponding lock groove on the door frame, thereby realizing the locking and unlocking.

[0023] A first handle 5 is fixedly installed on the housing 1, which can be used to push and pull the door from the outside.

[0024] Working Principle: When this utility model is in use, after the owner enters the unlock password or unlocks by touching the fingerprint button, the motor 18 drives the half gear 17 to rotate. The half gear 17 first drives the second gear 16 to rotate, the second gear 16 drives the second threaded rod 14 to rotate, and the second threaded rod 14 drives the slider 19 to slide. The slider 19 drives the second locking tongue 7 to slide and retract into the housing 1. At this time, the half gear 17 disengages from the second gear 16. Then, the motor 18 continues to drive the half gear 17 to rotate, so that the half gear 17 meshes with the first gear 15. The first gear 15 drives the first threaded rod 13 to rotate, and the first threaded rod 13 drives the sliding plate 12 to slide. The sliding plate 12 pushes the sliding rod 10 into the sleeve 11 and compresses the spring 25. The sliding rod 10 drives the first latch 6 to retract into the housing 1, completing the unlocking (when locking from the outside, the owner can lock by touching the fingerprint button with their finger; the locking steps are the reverse of the above). This allows the entrance door to be opened. After the door is opened, the motor 18 drives the half gear 17 to reverse, the half gear 17 drives the first gear 15 to reverse, the first gear 15 drives the first threaded rod 13 to reverse, and the first threaded rod 13 drives the sliding plate 12 to reset. Using the rebound force of the spring 25, the sliding rod 10 pushes the first latch 6 out of the housing 1 to reset. At this time, the motor 18 and the half gear 17 stop working. Then, the entrance door is closed from the outside to the inside. Since the side of the first latch 6 facing the inside is set at an angle, when the first latch 6 touches the door frame... When the first latch 6 is subjected to external force, it will retract into the housing 1 and compress the spring 25 through the sliding rod 10. When the entrance door is closed, the sliding rod 10 receives the rebound force of the spring 25, pushing the first latch 6 out and inserting it into the corresponding lock groove on the door frame, thereby closing the entrance door.

[0025] When the touch screen 3 is malfunctioning but still usable, a mechanical key can be inserted into the key plug 4, which drives the key plug 4 to rotate the third bevel gear 29, which in turn drives the first bevel gear 27, which in turn drives the half gear 17. This, along with other transmission components, enables locking and unlocking. After closing the door from the inside, the knob 9 can be rotated, which drives the second bevel gear 28, which in turn drives the first bevel gear 27, which in turn drives the half gear 17. This, along with other transmission components, causes the second lock tongue 7 to extend from the housing 1 and insert into the corresponding lock slot on the door frame to achieve reverse locking.

[0026] When the second latch 7 is not extended, the large gear 22 can be rotated indoors via the second handle 8. The large gear 22 rotates the small gear 23, which in turn rotates the rack 20. The rack 20 engages with the tooth groove 26 in the sliding rod 10, causing the sliding rod 10 to insert into the sleeve 11 and compress the spring 25. The sliding rod 10 causes the first latch 6 to retract into the housing 1. When the second handle 8 is released, the spring 25's rebound force causes the first latch 6 to reset and insert into the corresponding lock groove on the door frame, thus achieving locking and unlocking.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
