The first tooth plate and the second tooth plate are connected by the middle gear to form a closed transmission chain. When the handle is operated, the force is transmitted to the first tooth plate through the first dustproof box, thereby driving the gear to rotate.

The two first tooth plates and the second tooth plate surfaces are slidably connected to the limit plate surfaces through the sliding groove, realizing smooth and controlled movement of the tooth plate. The sliding groove ensures the straightness and accuracy of the tooth plate during sliding, while limiting unnecessary lateral movement, thereby improving the tightness and reliability of the entire transmission system. The limit plate plays a dual role here: on the one hand, it serves as a support point for the rotation of the gear, and on the other hand, it serves as a guide rail for the sliding of the tooth plate.

One side surface of the connecting block is in direct contact with the gear surface, which not only increases the direct support between the transmission components and provides additional stability for the rotational movement of the gear, but also helps to reduce shaking and noise during the operation of the gear, and improves the mechanical stability and service life of the entire door lock system. The positioning grooves provided on both side surfaces of the connection between the first dustproof box and the second dustproof box are in contact with the surface of the connecting block, which avoids mechanical jamming caused by misalignment and improves the smoothness of operation and the consistency of the dustproof effect.

During the operation of the door lock, as the dustproof box slides up and down, not only can the necessary lock body parts be exposed for easy operation, but also the closed state can be quickly restored when not in use, effectively preventing external pollutants such as dust and moisture from entering the interior of the door lock, protecting the components of the lock from damage, and extending the service life.

[0013] In order to improve the dustproof performance, preferably, the upper surface of the first dustproof box is in contact with the lower surface of the second dustproof box. Through the direct contact between the upper surface of the first dustproof box and the lower surface of the second dustproof box, the integrity of the dustproof structure is further consolidated, and the core mechanical components of the smart door lock are tightly wrapped and protected. It not only ensures that during the operation of the door lock, the two dustproof boxes can work together to form a continuous and closed dustproof barrier, effectively isolating dust, moisture and other tiny particles in the external environment from entering the interior of the door lock, but also reduces the existence of gaps through direct contact, thereby improving the efficiency of the dustproof effect.

[0023] The structure of the present utility model is described in detail below with reference to the accompanying drawings.

[0024] like Figures 1 to 5As shown, an embodiment of the present invention provides an intelligent door lock with a dustproof function, comprising a door lock 4, a mounting plate 5, a fixed box 6 and a movable groove 7. The movable groove 7 is through-opened on the surface of the fixed box 6, the front end surface of the fixed box 6 is fixedly connected to the rear surface of the door lock 4, the rear end surface of the fixed box 6 is fixedly connected to the front surface of the mounting plate 5, and two dustproof devices 1 are provided on the inner walls at the upper and lower ends of the movable groove 7. A fixing component 3 is provided on one side of the two dustproof devices 1. The dustproof device 1 is used to protect the door lock 4, and the fixing component 3 is used to adjust the operating state. The two dustproof devices 1 include a first tooth plate 101, a second tooth plate 102, a gear 103, a first dustproof box 104, a second dustproof box 105 and a handle 106. The surfaces of the two first tooth plates 101 are connected to the inner wall surfaces of the movable groove 7. The surfaces of the two first tooth plates 101 are meshed with the surfaces of the two gears 103, and the surfaces of the two gears 103 are meshed with the surfaces of the two second tooth plates 102. The surfaces of the two first tooth plates 101 are fixedly connected to the inner walls of the first dust-proof box 104 on both sides through a connecting rod. The surfaces of the two second tooth plates 102 are fixedly connected to the inner walls of the second dust-proof box 105 on both sides. The surface of the first dust-proof box 104 is fixedly connected to the surface of the handle 106. The surface of the second tooth plate 102 is slidably connected to the inner wall of the movable groove 7. The two first tooth plates 101 are slidably connected to the inner wall of the movable groove 7 to achieve a low-friction motion mechanism, and their meshing with the special gear 103 ensures the stability and efficiency of the transmission, so that the tooth plate can effectively prevent external dust from entering the key when moving. The transmission components improve the durability of the door lock 4 system. The first tooth plate 101 and the second tooth plate 102 are connected through the middle gear 103 to form a closed transmission chain. When the handle 106 is operated, the force is transmitted to the first tooth plate 101 through the first dustproof box 104, and then drives the gear 103 to rotate. This indirect transmission method not only reduces direct wear, but also effectively utilizes space to achieve the dual functions of dustproof and transmission. The first dustproof box 104 is fixedly connected to the handle 106, and the second dustproof box 105 is bound to the second tooth plate 102. The two are cleverly coordinated by moving up and down to form a dynamic dustproof barrier during the operation of the door lock 4. When the handle 106 is pulled down, the first dustproof box 104 drives the first tooth plate 101 and the transmission system to work. At the same time, the second dustproof box 105 slides upward, effectively isolating the dust and impurities in the external environment. Two limit plates 2 are provided on both sides of the inner wall of the movable groove 7. The surface of the limit plate 2 is rotatably connected to the surface of the gear 103 through a rotating shaft. The surfaces of the two first tooth plates 101 and the second tooth plate 102 are slidably connected to the surfaces of the two limit plates 2 through a sliding groove. The limit plates 2 added on both sides of the inner wall of the movable groove 7 are rotatably connected to the surface of the gear 103 through the rotating shaft. It not only provides a guiding effect for the rotation of the gear 103, but also increases the stability of the system. Ensure that the gear 103 remains stable and accurately positioned during the rotation process, avoiding unnecessary wear and noise. The surfaces of the two first tooth plates 101 and the second tooth plate 102 are slidably connected to the surface of the limit plate 2 through the sliding groove.The smoothness and control of the tooth plate movement are achieved, the slide groove ensures the straightness and accuracy of the tooth plate during the sliding process, while limiting unnecessary lateral movement, improving the tightness and reliability of the entire transmission system, and the limit plate 2 plays a dual role here: on the one hand, it serves as a support point for the rotation of the gear 103, and on the other hand, it serves as a guide rail for the sliding of the tooth plate. This integrated design effectively improves the smoothness of the operation of the door lock 4 and further strengthens the dust-proof effect, because the tighter component fit reduces the space for dust to invade. The fixed component 3 includes a limit groove 301, a fixed rod 302 and a connecting block 303. The limit groove 301 is evenly penetrated and opened on the surface of the gear 103 and the limit plate 2. The inner wall of the limit groove 301 is slidably connected to the surface of the four fixed rods 302. The front ends of the four fixing rods 302 are fixedly connected to the surface of the connecting block 303, and the limiting grooves 301 are evenly penetrated through the surfaces of the gear 103 and the limiting plate 2. The limiting grooves 301 position the key components, effectively suppressing unnecessary movement and improving the stability of the overall system. The four fixing rods 302 are connected to the inner walls of the limiting grooves 301 by sliding, and their front ends are firmly combined with the connecting block 303 to form a solid support system. When operating the door lock 4, by pushing the connecting block 303, the fixing rods 302 can be quickly and accurately embedded in the limiting grooves 301, thereby achieving the purpose of quickly fixing the gear 103 and the limiting plate 2, ensuring the absolute stability of the tooth plate position, avoiding displacement caused by vibration or external force, and improving the safety and reliability of the door lock 4. , and effectively prevents the first dustproof box 104 and the second dustproof box 105 from merging unexpectedly, maintains the internal cleanliness of the door lock 4, reduces the erosion of dust and foreign matter on the components, extends the service life of the door lock 4 and reduces the maintenance requirements, and significantly improves the dustproof isolation ability of the door lock 4. The surface of one side of the connecting block 303 is in contact with the surface of the gear 103. Positioning grooves 8 are provided on both sides of the connection between the first dustproof box 104 and the second dustproof box 105. The inner wall of the positioning groove 8 is in contact with the surface of the connecting block 303. The surface of one side of the connecting block 303 is in direct contact with the surface of the gear 103, which not only increases the direct support between the transmission components and provides additional stability for the rotational movement of the gear 103, which helps to reduce the gear 103 during operation. The shaking and noise in the door lock 4 are improved, and the mechanical stability and service life of the entire door lock 4 system are improved. The positioning grooves 8 on the two side surfaces of the connection between the first dustproof box 104 and the second dustproof box 105 are in contact with the surface of the connecting block 303, avoiding mechanical jamming caused by misalignment, and improving the smoothness of operation and the consistency of dustproof effect. The outer surface of the door lock 4 is slidably connected to the inner wall of the first dustproof box 104 and the second dustproof box 105. The rear end surfaces of the first dustproof box 104 and the second dustproof box 105 are slidably connected to the rear side surface of the fixed box 6. The sliding connection design of the outer surface of the door lock 4 and the inner wall of the first dustproof box 104 and the second dustproof box 105 ensures the smoothness of the door lock 4 panel when moving, reduces the operating resistance, and makes the external operation of the door lock 4 more natural.This improves user interaction satisfaction. The rear end surfaces of the first dustproof box 104 and the second dustproof box 105 are both slidably connected to the rear surface of the fixed box 6, forming a dynamic closed system. During the operation of the door lock 4, as the dustproof box slides up and down, it not only exposes the necessary lock body parts for easy operation, but also quickly returns to a closed state when not in use, effectively preventing external pollutants such as dust and moisture from entering the interior of the door lock 4, protecting the lock components from damage and extending the service life. The upper surface of the first dustproof box 104 is in contact with the lower surface of the second dustproof box 105. The direct contact between the upper surface of the first dustproof box 104 and the lower surface of the second dustproof box 105 further consolidates the integrity of the dustproof structure and achieves a tight wrapping and protection of the core mechanical components of the smart door lock 4. Not only does it ensure that during the operation of the door lock 4, the two dustproof boxes can work together to form a continuous and closed dustproof barrier, effectively isolating dust, moisture and other small particles in the external environment from entering the interior of the door lock 4, but also the direct contact reduces the presence of gaps, thereby improving the efficiency of the dustproof effect.

[0025] The working principle of this utility model:

[0026] When in use, by pulling the handle 106 downwards, the handle 106 is fixed to the surface of the first dust box 104. When the handle 106 is pulled down, the first dust box 104 will be driven to move downwards. At this time, the connecting rods on both sides of the inner wall of the first dust box 104 will pull the first tooth plate 101 for synchronous displacement. During the movement, the tooth surface of the first tooth plate 101 will mesh with the gear 103, and then through the meshing action, the second tooth plate 102 will move upwards. The second tooth plate 102 is also fixed to the connecting rod and connected to the second dust box 105. Therefore, when the first dust box 104 is pulled downwards, the second dust box 105 will move upwards. In this way, the door lock 4 will be fully exposed, making it convenient to unlock the door. When the door lock 4 needs to be operated, the connecting blocks 303 on both sides can be pushed inward. In this way, the fixing rods 302 on the surface of the connecting blocks 303 will be inserted into the limit grooves 301. The limit grooves 301 are a device that can limit the movement of objects. By inserting the fixing rods 302 into the limit grooves 301, the gear 103 can be fixed to the limit plate 2. This can ensure that the position of the tooth plate is fixed and prevent the first dustproof box 104 from merging with the second dustproof box 105. Therefore, when operating the door lock 4, the operation can be performed more stably to avoid misoperation or accidents.
