Description

Technical Field

[0001] This utility model relates to the technical field of door locks, and specifically discloses a lock assembly with high installation adaptability and a door lock latch box. Background Technology

[0002] Door locks, as a crucial component of building security and home protection, have undergone continuous evolution in function and design with technological advancements. Traditional mechanical locks primarily rely on physical structures to lock and unlock doors, but their functionality is relatively limited and cannot meet the demands of modern intelligent and automated systems. With the development of electronic technology, smart door locks have gradually become the mainstream in the market. Smart door locks not only possess the security of traditional locks but also integrate electronic components to achieve remote control, status monitoring, and other functions, providing users with a more convenient and secure experience. However, in the design of smart door locks, accurately detecting the door's open / closed status and ensuring the reliable operation of the lock remains a critical issue.

[0003] A Hall effect sensor is a magnetic sensor based on the Hall effect, widely used in door lock systems to detect the open / closed state of a door. In door lock design, the Hall effect sensor can be installed between the door frame and the door body, and achieves status monitoring through cooperation with a magnet. When the door is closed, the magnet approaches the Hall effect sensor, the magnetic field strength changes, the Hall effect sensor senses the magnetic field and outputs a corresponding signal, thus confirming that the door is fully closed. This detection method not only prevents the latch from moving when the door is not fully closed, avoiding motor damage or the latch being in an unsafe state, but also provides real-time status feedback for the smart door lock system, improving the system's security and reliability.

[0004] However, the detection effectiveness of Hall elements is highly dependent on the distance between the magnet and the Hall element, as well as the magnetic field strength, which can be affected by various factors in practical applications. During actual installation, the gap between the door leaf and the door frame may change due to manufacturing errors, inaccurate installation, or deformation caused by long-term use. When the gap is too large, the distance between the magnet and the Hall element exceeds the effective sensing range, causing the Hall element to fail to sense the magnetic field properly and thus failing to accurately detect the door's open / closed state. Furthermore, existing technologies lack effective adjustment mechanisms. Once a sensing failure occurs, it is usually necessary to readjust the installation position or replace components, which not only increases installation and maintenance costs but also reduces system reliability and user experience. Therefore, improving the adaptability of lock components under different installation conditions while simplifying the installation and maintenance process has become an urgent technical problem to be solved. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a lock assembly and door lock box with high installation adaptability.

[0006] On the one hand, this utility model discloses a lock assembly with high installation adaptability, which adopts the following technical solution:

[0007] A highly adaptable lock assembly includes a lock body and a snap box that mates with the lock body. The lock body is provided with a circuit board and a Hall element electrically connected thereto. The snap box is provided with a magnet that mates with the Hall element and a telescopic member for adjusting the distance between the magnet and the Hall element.

[0008] Preferably, the telescopic component is a screw, the magnet is mounted on the screw, and the buckle box is provided with an internal thread for the screw to be matched and installed.

[0009] Preferably, the buckle box is provided with a fixing nut, and the internal thread is provided in the fixing nut.

[0010] Preferably, the screw is provided with a clamping nut, and the head of the screw is clamped between the clamping nut and the magnet.

[0011] Preferably, a spring is fitted onto the screw, with one end of the spring abutting against the inner wall of the buckle box and the other end abutting against the clamping nut.

[0012] Preferably, the magnet is ring-shaped, and a connecting hole is provided in the middle of the magnet for the screw tail to pass through, and the screw head is blocked outside the connecting hole.

[0013] Preferably, the connecting hole is a countersunk hole that matches the screw head.

[0014] Preferably, the buckle box is provided with a receiving groove for the magnet to be inserted and moved.

[0015] Preferably, the device further includes a buckle plate disposed outside the buckle box, the buckle plate being provided with a fixing member.

[0016] On the other hand, this utility model discloses a door lock latch box, which is the latch box with magnet and telescopic component mentioned above.

[0017] Compared with the prior art, the present invention has at least the following beneficial effects:

[0018] This invention, by incorporating a magnet and a telescopic component in the latch box, allows for adjustment of the distance between the magnet in the latch box and the Hall element in the lock body during actual installation, even if the gap between the door leaf and the door frame is too large. As the distance between the Hall element and the magnet decreases, the magnetic field strength increases, and the voltage or signal strength output by the Hall element also increases, thus meeting the activation conditions. This enables the detection and judgment of the door's opening and closing status, avoiding the tedious work of remanufacturing or reinstalling the door due to production or installation errors. The adjustment method of this solution is more efficient and convenient. Attached Figure Description

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] This embodiment discloses a lock assembly with high installation adaptability and a door lock strike box, referencing... Figure 1-4 The lock assembly includes a lock body 1 and a snap box 2 that cooperates with the lock body 1. The lock body 1 is installed on the door leaf, and the snap box 2 is installed on the door leaf. The lock body 1 and the snap box 2 cooperate to realize the opening and closing of the door lock. The snap box 2 may be provided with a snap plate 21, and the snap plate 21 is provided with a fixing member 22. The fixing member 22 may be a self-tapping screw, which can be used to fix the snap plate 21 together with the snap box 2 to the door frame. Of course, in other embodiments, the snap box 2 may be directly fixed to the door frame.

[0027] The lock body 1 includes a circuit board and a Hall element 11 electrically connected to it. The latch box 2 includes a magnet 23 that mates with the Hall element 11. The latch box 2 also includes a telescopic component for adjusting the distance between the magnet 23 and the Hall element 11. Specifically, in this embodiment, the telescopic component is a screw 24, with the magnet 23 mounted on the screw 24. The latch box 2 has an internal thread for the screw 24 to be installed. If, after actual installation, it is found that the gap between the door leaf and the door frame is too large, preventing the Hall element 11 from emitting a door leaf position detection signal, or if the detection signal is unstable, the distance between the magnet 23 and the Hall element 11 can be adjusted to a suitable level by screwing the screw 24 on the latch box 2. This adjustment method is convenient and does not require reinstalling the door leaf, making it particularly suitable for whole-house custom installation needs. Of course, in addition to screws, telescopic components such as telescopic slides can also be used. However, screws not only have good versatility and are cheaper to manufacture, but also provide better position fixation after adjustment. Therefore, screws are the preferred option for telescopic components.

[0028] As a preferred embodiment, the snap box 2 has a mounting through hole, and a fixing nut 25 is fixed at the mounting through hole. The aforementioned internal thread is provided in the fixing nut 25, and the screw 24 is connected to the fixing nut 25 through the thread to install it on the snap box 2. By adopting the above design, the snap box 2 does not need to be molded to set the threaded hole during production; only the general-purpose part, the fixing nut 25, needs to be installed, thus reducing production costs.

[0029] As a preferred embodiment, the screw 24 is provided with a clamping nut 26, and the head of the screw 24 is clamped between the clamping nut 26 and the magnet 23, thereby fixing the magnet 23 and the screw 24. The fixing method is simple and easy to assemble. Specifically, in this embodiment, the magnet 23 is annular, and the middle of the magnet 23 is provided with a connecting hole for the tail of the screw 24 to pass through. The head of the screw 24 is blocked outside the connecting hole. By adopting the above design, the user can adjust the screw 24 by turning it from the outside. During the adjustment, the axial projection shape of the magnet 23 remains unchanged, reducing the space occupied in the buckle box 2. In addition, the buckle box 2 is provided with a receiving groove 201 for the magnet to be inserted and moved. When the spacing is appropriate, the magnet 23 can be moved into the receiving groove 201 to be embedded or flush. The connecting hole can be a countersunk hole that matches the head of the screw 24, which can improve the aesthetics.

[0030] As a preferred embodiment, a spring 27 is fitted onto the screw 24. One end of the spring 27 abuts against the inner wall of the receiving groove 201 (i.e., the inner wall of the snap-fit ​​box 2), and the other end abuts against the clamping nut 26. By adopting the above design, when the spring 27 is compressed, it will apply a reverse elastic force to the clamping nut 26, which can press the clamping nut 26 tightly against one side of the head of the screw 24. This preload can prevent the clamping nut 26 from loosening due to vibration or external force during operation, thereby improving the reliability of the connection.

[0031] The technical solution provided by this utility model has been described in detail above. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
