[0004] In view of the problems existing in the prior art, the present invention provides an easy-to-install smart door lock that can overcome the above problems or at least partially solve the above problems.

[0005] The utility model is realized as follows: an intelligent door lock that is easy to install comprises a main body, a door lock, a fixing plate and a mounting groove, wherein the mounting groove is provided on the surface of the main body, the surface of the fixing plate is fixedly connected to the rear end surface of the door lock, the surface of the fixing plate is slidably connected to the inner wall of the mounting groove, four fixing devices are provided inside the main body, and an auxiliary mechanism is provided on the surface of the main body;

[0006] The fixing device is used to install and fix the door lock;

[0007] The auxiliary mechanism is used to enhance the fixing effect.

[0008] In order to improve the reliability of long-term use, preferably, the fixing device includes a spring, a first tooth plate, a gear, a second tooth plate, a clamping plate and a limiting slot, and the four limiting slots are evenly arranged around the mounting slot, and the lower sides of the inner walls of the four limiting slots are slidably connected to the four first tooth plate surfaces through sliding slots, the four first tooth plate surfaces are meshed with the four gear surfaces, the four gear surfaces are meshed with the four second tooth plate surfaces, the front ends of the four second tooth plates are fixedly connected to the two clamping plate surfaces, and the rear ends of the four second tooth plates are fixedly connected to the four spring surfaces. Through the four limiting slots evenly distributed around the mounting slot, not only the position accuracy of the door lock during installation is ensured, but also a stable guide is provided for the sliding of the entire lock body through the sliding connection with the first tooth plate, effectively avoiding The spring mechanism inside the door lock works in conjunction with the tooth plate system to achieve automatic adjustment and initial tightening during installation. When the door lock is pushed in, the interaction between the bevel block and the positioning groove causes the first tooth plate to slide along the limit groove, and then drives the second tooth plate forward through the gear transmission, thereby achieving initial stability through the friction between the clamping plate and the surface of the fixed plate. The initial fixation can be completed without additional tools, which improves the convenience and safety of installation. Through the meshing between the gear and the tooth plate, and the elastic support of the spring, the door lock can maintain good stability and durability when subjected to tension and pressure changes in daily use. Such a mechanical transmission system effectively disperses external forces, reduces wear, and extends the service life of the product.

[0009] In order to improve the service life, preferably, the auxiliary mechanism includes a fixing block, a limiting block, a positioning plate and a fixing slot, the four fixing slots are opened on the four surfaces around the lower side of the fixing plate, the four inner walls of the fixing slots are slidably connected with the four surfaces of the positioning plates, the upper end surface of the front side of the main body is rotatably connected with the surface of the fixing block through a rotating shaft, the surface of the limiting block is slidably connected with the lower end surface of the front side of the main body, and the four fixing slots are arranged around the lower side of the fixing plate to achieve sliding cooperation with the positioning plate, so that the positioning plate can be quickly and accurately aligned with the position during the insertion into the fixing slot, which greatly simplifies the installation steps, ensures that the door lock body can be quickly and accurately positioned, reduces assembly time and errors, and improves user experience. By setting a rotating shaft connection between the upper end of the front side of the main body and the fixed block, the user can easily rotate the fixed block after the installation is completed, so that it fits tightly with the upper end of the door lock and is firmly fixed. This rotating locking mechanism is not only easy to operate, but also can be fine-tuned according to actual needs to ensure the fastening effect of the upper part, thereby enhancing the overall stability of the door lock. It is connected to the lower end of the front side of the main body through a sliding connection through the limit block. After the installation is completed, the limit block is pushed upward to make it contact with the lower end of the door lock, forming a two-way support structure up and down. This mechanism effectively prevents any potential shaking of the door lock during use, and ensures that the door lock is stable and does not fall off even in the face of external force impact or long-term use, significantly improving safety performance.

[0010] The two side surfaces of the four gears are rotatably connected to the inner walls of the four limit grooves through bearings, and the four spring surfaces are rotatably connected to the upper inner walls of the four limit grooves. The two clamping plate surfaces are slidably connected to the inner walls of the limit grooves, and the two clamping plate surfaces are in contact with the surface of the fixed plate. By sliding the four second tooth plate surfaces to the corresponding four limit groove inner walls through the sliding grooves, the second tooth plate can move smoothly in the limit groove, which not only simplifies the alignment operation during installation, but also can be flexibly adjusted when the door lock is subjected to force, ensuring the consistent movement between the tooth plate and related components, and enhancing the overall dynamic stability. The two side surfaces of the four gears are rotatably connected to the inner walls of the limit grooves through bearings, reducing The reduction in friction improves transmission efficiency, while also ensuring the smoothness and precision of the gears during rotation, allowing the gear set to transmit power more effectively and drive the door lock to open and close more smoothly. The surfaces of the four springs are slidably connected to the upper inner wall of the limit groove, ensuring that the springs can freely expand and contract with the movement of the door lock while providing the necessary rebound force, maintaining the necessary tension to keep the door lock stable without affecting its service life or response speed due to excessive restraint. The surfaces of the two clamping plates not only form sliding contact with the inner wall of the limit groove, but also fit closely with the surface of the fixed plate directly, which not only simplifies the adjustment of the clamping plate position during installation, but also uses direct contact with the fixed plate to further enhance the stability of the door lock after installation by using friction, ensuring that even when the door body is subjected to external force, the door lock will not easily loosen or displace.

[0011] In order to improve practicality, preferably, an elastic block is provided at the lower end of the limit block, and the surface of the elastic block is slidably connected to the lower side surface of the front end of the main body. The introduction of the elastic block enables the limit block to provide a certain buffering effect when it slides in contact with the lower side surface of the front end of the main body. When the door body vibrates slightly during the opening and closing process or is impacted by external forces, the elastic block can absorb and disperse these forces, reduce the impact force directly transmitted to the door lock structure, protect the door lock from damage, and extend its service life. The elastic characteristics of the elastic block allow it to automatically adjust its position within a certain range to adapt to the tiny gap between the door body and the door frame. This adaptive ability ensures that the door lock can maintain good sealing and stability even when the door body expands or contracts due to temperature changes in different seasons, reducing the loosening problem caused by gap changes. The sliding connection design between the elastic block and the lower surface of the front end of the main body simplifies the installation and debugging process of the door lock. During installation, the flexibility of the elastic block can help to quickly align and fit the door body. Even if the first installation is not fully in place, it can be perfectly fitted through slight adjustments without the need for complex tools or professional knowledge. Similarly, during later maintenance or adjustments, the easy operation of the elastic block also greatly reduces the maintenance burden.

[0012] In order to improve the stability of installation, preferably, the front ends of the four second tooth plates are fixedly connected to the rear side surfaces of the four positioning plates, the surface of the fixing block is slidably connected to the upper end surface of the door lock, and the surface of the limit block is slidably connected to the lower end surface of the door lock. The front ends of the four second tooth plates are fixedly connected to the rear side surfaces of the corresponding four positioning plates, ensuring that during the installation of the door lock, the second tooth plates can be accurately entered into the fixing grooves through the guidance of the positioning plates to achieve fast and accurate positioning. This rigid connection not only simplifies the installation steps, but also enhances the overall rigidity between the door lock components, improves the anti-deformation ability and service life of the door lock, and the sliding of the fixing block surface and the upper end surface of the door lock The connection provides a flexible adjustment mechanism for the final fixation of the door lock. According to actual installation requirements, the upper part can be firmly locked by simply sliding the fixing block to a position that fits tightly with the upper end of the door lock. No complicated tools or tedious operating steps are required, which greatly improves the convenience and efficiency of installation. The sliding connection between the surface of the limit block and the lower surface of the door lock, assisted by the design of the fixing block, together constitutes a double safety guarantee for the upper and lower ends of the door lock. By pushing the limit block upward until it is in close contact with the lower end of the door lock, the door lock can be effectively prevented from sagging or shaking during use, ensuring that the door lock always remains level and stable, thereby improving safety and reliability during use.

[0013] In order to improve the durability of the device, preferably, the front ends of the four first tooth plates are provided with oblique blocks, and the lower surface of the fixed plate is provided with four positioning grooves, the four positioning groove surfaces are slidingly connected to the four oblique block surfaces, and the lower surfaces of the four oblique blocks are slidingly connected to the inner walls of the installation grooves. The oblique block design at the front ends of the four first tooth plates slides with the four positioning grooves preset on the lower surface of the fixed plate, ensuring that the door lock can quickly and accurately find the predetermined position during installation, and the sliding of the oblique block along the positioning groove simplifies the alignment process, and the sliding connection between the lower surface of the oblique block and the inner wall of the installation groove constitutes a stable structure, which effectively prevents the door lock from being displaced or loosened due to external force during use, and utilizes the natural bite principle of the inclined surface. Even when the door is frequently opened and closed or subjected to accidental impact, the door lock can remain stable, thereby enhancing the overall safety.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] The utility model is provided with a fixing device, an auxiliary mechanism, a spring, a first tooth plate, a gear, a second tooth plate, a clamping plate, a limiting groove, a fixing block, a limiting block, a positioning plate and a fixing groove. The fixing device is used to install and fix the door lock, and the auxiliary mechanism is used to strengthen the fixing effect. Through four limiting grooves evenly distributed around the installation groove, it not only ensures the position accuracy of the door lock during installation, but also provides a stable guide for the sliding of the entire lock body through the sliding connection with the first tooth plate, effectively avoiding the deviation or jamming that may occur during the installation process, and enhancing the smoothness and accuracy of the installation. The spring mechanism inside the door lock and the tooth plate system work together to realize automatic adjustment and preliminary tightening during installation. When the door lock is pushed in, the inclined block and the fixing plate are in a stable position. The interaction of the positioning grooves causes the first tooth plate to slide along the limiting groove, and then drives the second tooth plate to move forward through the gear transmission, so that the initial stability is achieved through the friction between the clamping plate and the surface of the fixing plate. The initial fixation can be completed without additional tools, which improves the convenience and safety of installation.

The spring 101 mechanism and the tooth plate system inside the door lock 7 The coordinated work of the two realizes automatic adjustment and preliminary tightening during installation. When the door lock 7 is pushed in, the interaction between the inclined block 4 and the positioning groove 5 causes the first tooth plate 102 to slide along the limit groove 106, and then drives the second tooth plate 104 to move forward through the gear 103, thereby achieving preliminary stability through the friction between the clamping plate 105 and the surface of the fixing plate 8. The preliminary fixation can be completed without additional tools, which improves the convenience and safety of installation. Through the engagement between the gear 103 and the tooth plate, and the elastic support of the spring 101, the door lock 7 can maintain good stability and durability when it withstands the tension and pressure changes in daily use. Such a mechanical transmission system effectively disperses external forces, reduces wear, and extends the service life of the product, assisting The mechanism 2 includes a fixing block 201, a limiting block 202, a positioning plate 203 and a fixing slot 204. The four fixing slots 204 are provided on the four surrounding surfaces of the lower side of the fixing plate 8. The inner walls of the four fixing slots 204 are slidably connected to the surfaces of the four positioning plates 203. The upper end surface of the front side of the main body 6 is rotatably connected to the surface of the fixing block 201 through a rotating shaft. The surface of the limiting block 202 is slidably connected to the lower end surface of the front side of the main body 6. The four fixing slots 204 are arranged around the lower side of the fixing plate 8 to achieve sliding cooperation with the positioning plate 203. The positioning plate 203 can be quickly and accurately aligned in the process of being inserted into the fixing slot 204, which greatly simplifies the installation steps, ensures that the main body 6 of the door lock 7 can be quickly and accurately positioned, reduces assembly time and errors, and improves user experience.By arranging a rotating shaft connection between the upper end of the front side of the main body 6 and the fixing block 201, the user can easily rotate the fixing block 201 after the installation is completed, so that it is tightly fitted with the upper end of the door lock 7 and firmly fixed. This rotating locking mechanism is not only easy to operate, but also can be fine-tuned according to actual needs to ensure the fastening effect of the upper part, thereby enhancing the overall stability of the door lock 7. The limit block 202 is connected to the lower end of the front side of the main body 6 through a sliding connection. After the installation is completed, the limit block 202 is pushed upward to make it contact with the lower end of the door lock 7, forming a two-way support structure in an upper and lower direction. This mechanism effectively prevents any potential shaking of the door lock 7 during use, and ensures that the door lock 7 is stable and does not fall off even in the face of external impact or long-term use, thereby significantly improving safety performance. The surfaces of the four second tooth plates 104 are slidably connected to the inner walls of the four limit grooves 106 through sliding grooves, the two side surfaces of the four gears 103 are rotatably connected to the inner walls of the four limit grooves 106 through bearings, the surfaces of the four springs 101 are slidably connected to the upper inner walls of the four limit grooves 106, the surfaces of the two clamping plates 105 are slidably connected to the inner walls of the limit grooves 106, and the surfaces of the two clamping plates 105 are in contact with the surface of the fixed plate 8.

In terms of quality, the two side surfaces of the four gears 103 are rotationally connected with the inner wall of the limiting groove 106 through bearings, which reduces friction and improves transmission efficiency. At the same time, it also ensures the stability and accuracy of the gear 103 during rotation, so that the gear 103 group can transmit power more effectively and drive the door lock 7 to open and close more smoothly. The surfaces of the four springs 101 are slidingly connected with the upper inner wall of the limiting groove 106, ensuring that the spring 101 can freely expand and contract with the movement of the door lock 7 while providing the necessary rebound force, maintaining the necessary tension to keep the door lock 7 stable without affecting its service life or response speed due to excessive constraint. The surfaces of the two clamping plates 105 not only form sliding contact with the inner wall of the limiting groove 106, but also directly contact the surface of the fixed plate 8 The close fit between the surfaces not only simplifies the adjustment of the clamping plate 105 position during installation, but also further enhances the stability of the door lock 7 after installation by directly contacting the fixing plate 8 and utilizing friction, ensuring that even when the door body is subjected to external force, the door lock 7 will not easily loosen or shift. An elastic block 3 is provided at the lower end of the limit block 202, and the surface of the elastic block 3 is slidably connected to the lower side surface of the front end of the main body 6.

When the door body generates slight vibrations or is impacted by external forces during the opening and closing process, the elastic block 3 can absorb and disperse these forces, thereby reducing the impact force directly transmitted to the door lock 7 structure, protecting the door lock 7 from damage, and extending its service life.Moreover, the elastic property of the elastic block 3 allows it to automatically adjust its position within a certain range to adapt to the slight gap changes between the door body and the door frame. This adaptive ability ensures that the door lock 7 can maintain good sealing and stability even when the door body expands or contracts due to temperature changes in different seasons, reducing the loosening problem caused by gap changes. The sliding connection design between the elastic block 3 and the lower surface of the front end of the main body 6 simplifies the installation and debugging process of the door lock 7. During installation, the flexibility of the elastic block 3 can help to quickly align and fit the door body. Even if the first installation is not fully in place, a perfect fit can be achieved through slight adjustments without the need for complex tools or professional knowledge. Similarly, during later maintenance or adjustments, the easy operation of the elastic block 3 also greatly reduces the maintenance burden. The front ends of the four second tooth plates 104 are fixedly connected to the rear side surfaces of the four positioning plates 203, the surface of the fixing block 201 is slidably connected to the upper end surface of the door lock 7, and the surface of the limit block 202 is slidably connected to the lower end surface of the door lock 7. The front ends of the four second tooth plates 104 are fixedly connected to the rear side surfaces of the corresponding four positioning plates 203, ensuring that during the installation of the door lock 7, the second tooth plates 104 can be accurately entered into the fixing grooves 204 through the guidance of the positioning plates 203, achieving fast and accurate positioning. This rigid connection not only simplifies the installation steps, but also enhances the overall rigidity between the components of the door lock 7, improves the anti-deformation ability and service life of the door lock 7, and the sliding connection between the surface of the fixing block 201 and the upper end surface of the door lock 7 provides flexibility for the final fixation of the door lock 7. The adjustment mechanism can be adjusted according to actual installation needs by simply sliding the fixing block 201 to a position that is tightly fitted with the upper end of the door lock 7, thereby achieving a firm locking of the upper portion without the need for complicated tools or tedious operating steps, which greatly improves the convenience and efficiency of installation. The sliding connection between the surface of the limit block 202 and the lower end surface of the door lock 7, together with the design of the fixing block 201, constitutes a double safety guarantee at the upper and lower ends of the door lock 7. By pushing the limit block 202 upward until it is in close contact with the lower end of the door lock 7, the door lock 7 can be effectively prevented from sagging or shaking during use, ensuring that the door lock 7 always remains in a horizontal and stable state, thereby improving the safety and reliability of use. The front ends of the four first tooth plates 102 are provided with an inclined block 4, and the lower end of the fixing plate 8 is provided with an inclined block 4. Four positioning grooves 5 are provided on the surface. The surfaces of the four positioning grooves 5 are slidably connected to the surfaces of the four inclined blocks 4. The lower surfaces of the four inclined blocks 4 are slidably connected to the inner walls of the installation grooves 9. The inclined blocks 4 at the front ends of the four first tooth plates 102 are designed to slide and dock with the four positioning grooves 5 preset on the lower surface of the fixing plate 8, ensuring that the door lock 7 can quickly and accurately find the predetermined position during installation. The sliding of the inclined blocks 4 along the positioning grooves 5 simplifies the alignment process. The sliding connection between the lower surface of the inclined blocks 4 and the inner walls of the installation grooves 9 forms a stable structure, effectively preventing the door lock 7 from being displaced or loosened due to external forces during use. The natural engagement principle of the inclined surfaces is utilized to maintain the stability of the door lock 7 even in the case of frequent door opening and closing or accidental impact, thereby enhancing overall safety.

[0024] The working principle of this utility model:

[0025] When in use, first, it is necessary to push the door lock 7 into the installation groove 9 pre-opened on the main body 6, and then fix the rear side surface of the door lock 7 to the surface of the fixing plate 8. At this time, by pushing the door lock 7 inward, the positioning groove 5 at the bottom of the fixing plate 8 will come into contact with the four inclined blocks 4 at the bottom of the installation groove 9. The inclined blocks 4 push the first tooth plate 102 to slide into the limiting groove 106 along the slope on the positioning groove 5. In the process of the first tooth plate 102 moving along the inner wall of the limiting groove 106, it engages with the gear 103, thereby driving the second tooth plate 104 to move toward the surface of the fixing plate 8, and the clamp fixed at the front end of the second tooth plate 104 The holding plate 105 contacts the surfaces on both sides of the fixing plate 8 and realizes the initial fixation of the door lock 7 through relative friction with its surface. At this time, the positioning plate 203 at the front end of the second tooth plate 104 will be simultaneously inserted into the fixing groove 204 opened around the fixing plate 8, thereby further strengthening the fixation of the door lock 7. After the door lock 7 is installed, it is necessary to rotate the fixing block 201 to make it contact with the upper end of the door lock 7 and fix it. At the same time, push the limit block 202 upward to make it contact with the lower end of the door lock 7. This can prevent the door lock 7 from shaking after installation, thereby preventing the door lock 7 from falling.
