Description

Technical Field

[0001] This invention relates to the technical field of locks, and more specifically to a lock with status monitoring to prevent accidental locking. Background Technology

[0002] In existing lock applications, increasingly intelligent designs are emerging. The use of smart keys for unlocking and closing has indeed brought great convenience, eliminating the cumbersome issues of purely mechanical unlocking being susceptible to external interference. However, especially for smart locks on cabinet doors such as electrical control panels, for the security of professional users, they typically still require a combination of mechanical and smart key designs, including corresponding identification codes and mechanical lock cylinders. In reality, with unified management of multiple control panels, there is a greater need for easy identification of the open / closed status of each lock, and even remote monitoring of the opening and closing of multiple control panel doors. However, existing devices only allow user identification and, at most, recording via the corresponding smart key, cannot provide unified, real-time management. Therefore, there is an urgent need to design a lock with real-time monitoring of open / closed status to prevent human errors such as accidental unlocking or failure to lock after use. Summary of the Invention

[0003] To address the problems existing in the prior art, the present invention aims to provide a lock with status monitoring to prevent accidental locking. The lock of the present invention has a reasonable structure, integrates opening and closing status monitoring functions, can perform unified background detection, and is adaptable to installation in various types of cabinets.

[0004] The present invention provides a lock with status monitoring to prevent accidental locking, including a lock body. The rear side of the lock body is mounted on a cabinet via a mounting plate. A gear box is also provided on the mounting plate. A rotating component is rotatably connected to the lock body. The rotating component is linked with the gear box and is used to open and close the cabinet. One side of the rotating component is open and a handle assembly is hinged along the front-back direction. The handle assembly, located away from the rotating part, is provided with a smart code chip, a lock cylinder, and a lock tongue arranged sequentially from top to bottom. The smart code chip is used for code matching and identification with the smart key. The handle assembly also includes a control circuit board and a reed switch. The control circuit board is electrically connected to the smart code chip and the reed switch, respectively. The lock body is provided with a groove that is adapted to the handle assembly, and the groove is provided with a recess corresponding to the position of the bolt, and a magnetic element is also embedded in the groove corresponding to the position of the reed switch.

[0005] In one embodiment, the handle assembly extends downward from the end away from the rotating member and engages with the latch to form a hook shape, and the magnetic element is located between the latch and the reed switch.

[0006] In one embodiment, a fixed button is provided at the end of the lock body away from the rotating member, the fixed button being used to engage with the end of the handle assembly.

[0007] In one embodiment, a column protrudes from one side of the bottom of the lock cylinder, and a groove adapted to the column is provided on the lock tongue. The lock cylinder rotates in the vertical direction, thereby causing the lock tongue to move up and down in a straight line.

[0008] In one embodiment, a dust cover is rotatably connected above the smart chip, and the dust cover is marked.

[0009] In one embodiment, the end of the handle assembly is hinged to the rotating member via a pivot, on which a compression spring is fitted. The compression spring is used to move the handle assembly away from the groove on the lock body in its natural state.

[0010] In one embodiment, the length of the handle assembly is equal to the length of the lock body. .

[0011] In one embodiment, a lever is provided on the rear side of the gearbox, and the lever rotates synchronously when the rotating component is driven to rotate by the handle assembly.

[0012] In one embodiment, the gear box is further provided with a gear that rotates synchronously with the rotating component, and the side of the gear box is provided with a rack that meshes with the gear. The gear box is slidably connected to the mounting plate.

[0013] In one embodiment, a positioning plate and a pressure plate are sequentially provided on the rear side of the lock body corresponding to the position of the lock cylinder.

[0014] Compared with the prior art, the beneficial effects of the technical solution of the present invention are: This invention features a compact structure and reasonable design, improving the durability and stability of the lock. Simultaneously, the lock incorporates an opening / closing status monitoring function. Through the induction relationship between the built-in reed switch and magnetic components, it can collect real-time data on the lock's opening and closing status.

Detailed Implementation

[0018] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0019] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The technical solution of this invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] like Figures 1-6 As shown, the present invention provides a lock with status monitoring to prevent accidental locking, including a lock body 1. The rear side of the lock body 1 is fixed to the cabinet via a mounting plate 2. The mounting plate 2 is also provided with a gear box 3. A rotating component 4 is rotatably connected to the lock body 1. The rotating component 4 is linked with the gear box 3 and is used to open and close the cabinet. One side of the rotating component 4 is open and a handle assembly 5 is hinged along the front-back direction. The handle assembly 5, away from the rotating part 4, is provided with a smart code chip 51, a lock cylinder 52 and a lock tongue 53 in sequence from top to bottom. The smart code chip 51 is used to identify the smart key. The handle assembly 5 is also provided with a control circuit board 54 and a reed switch 55. The control circuit board 54 is electrically connected to the smart code chip 51 and the reed switch 55 respectively. The lock body 1 has a groove that is compatible with the handle assembly 5, and a groove 11 is provided in the groove corresponding to the position of the lock tongue 53. A magnetic element 12 is also embedded in the groove corresponding to the position of the reed switch 55.

[0021] When the smart key is inserted, it is a self-locking key, meaning it cannot be pulled out when turned to the unlocked state. The control circuit board 54 can also be further equipped with a wireless connection module. When the reed switch 55 senses the magnetic element 12, it connects the circuit and feeds back the smart code chip 51 so that the inserted smart key receives the unlocked or locked status. Even if it is in a false locked state, that is, the handle assembly 5 pops up but the bolt 53 has extended and reset, the smart key can display an unlocked state to remind the user. At this time, it can also be connected wirelessly to provide real-time feedback to the management background on the actual status of the lock being unlocked and correctly locked.

[0022] The innovative design of this invention not only features a compact and rational structure with tight connections between components and smooth transmission, significantly improving the durability and stability of the lock; but also incorporates an integrated opening and closing status monitoring function. Through the sensing relationship between the built-in reed switch 55 and the magnetic component 12, it can collect real-time data on the lock's opening and closing status. Combined with the design of the control circuit board 54, it can further utilize wireless connection modules such as Bluetooth on the control circuit board 54 to accurately and in real-time transmit status information to the corresponding smart key or management backend. This enables unified backend monitoring and centralized control of locks in multiple areas and batches. Management personnel can remotely view the real-time status and historical opening and closing records of each lock, promptly detect abnormal opening and closing situations, and respond quickly, greatly enhancing the intelligence and convenience of security management.

[0023] Furthermore, this lock boasts significant advantages in installation adaptability. Its pre-installed positioning plate and other structural features are compatible with various cabinet installation scenarios, such as power cabinets, communication cabinets, and industrial control equipment cabinets, eliminating the need for custom-made adapters and effectively reducing installation and modification costs and time. Overall, this lock combines structural reliability, intelligent monitoring, and installation adaptability, making it highly valuable for market promotion in multiple fields such as industrial security, data center management, and smart warehousing, with broad application prospects and commercial potential.

[0024] In practical applications, mounting plate 2 can be adapted to the installation of two-hole or three-hole locks on various screen cabinets. In particular, a positioning plate 14 and a pressure plate 15 are sequentially provided on the rear side of the lock body 1 corresponding to the lock cylinder 52. The positioning plate 14 is used to adapt to the locking position of the screen cabinet, so that when the rotating part 4 is driven to rotate by the handle assembly 5, the lever 31 provided on the rear side of the gear box 3 rotates synchronously and engages in the corresponding slot, forming the effect of a secondary lock tongue. Furthermore, the pressure plate 15 further reinforces the positioning plate 14. This part can be welded and fixed to the mounting plate 2 according to the needs of the screen cabinet, so that the gear box 3 is also fixedly connected. The rotation of the rotating part 4 only drives the lever 31 to engage in the corresponding slot. The pressure plate 15 can also be slidably connected to the cabinet, cooperating with the sliding connection between the gear box 3 and the mounting plate 2. The gear box 3 is also equipped with a gear 32 that rotates synchronously with the rotating part 4. The side of the gear box 3 is equipped with a rack that meshes with the gear 32. So when the rotating part 4 rotates, in addition to driving the lever 31 to rotate, it will also drive the gear 32 to move up and down, so that the actual movement trajectory of the lever 31 is parabolic, to adapt to different cabinet door lock installation methods.

[0025] Furthermore, regarding the handle assembly 5, one end of the handle assembly 5 is identified by the smart key after insertion, and the smart key is matched with the corresponding smart chip 51. One smart key can correspond to only one area or one lock. Successful identification allows the lock cylinder 52 to rotate, thereby causing the bolt 53 to extend and retract. Figure 2 and Figure 6 As shown, a column protrudes from one side of the bottom of the lock cylinder 52, and a groove on the bolt 53 is adapted to the column. The lock cylinder 52 rotates vertically, thereby moving the bolt 53 up and down in a linear motion. The lock body 1 has a groove 11 inside the slot that adapts to the bolt 53. The overall shape is such that the end of the handle assembly 5 away from the rotating part 4 extends downward and cooperates with the bolt 53 to form a hook shape, which can better lock the position of the handle assembly 5. During this unlocking and locking process, the handle assembly 5 also contains a control circuit board 54 and a reed switch 55. When the magnetic component 12 on the lock body 1, i.e., the magnet, senses the reed switch 55, it indicates that the handle assembly 5 has been embedded in the groove. Combined with the rotation of the smart key, the bolt 53 engages in the groove 11, thus determining that the lock is in the locked state. If only the bolt 53 extends but the reed switch 55 does not sense the magnet, the control circuit board 54 is not activated, allowing remote determination that the lock is not properly locked. Furthermore, the magnetic element 12 corresponding to the reed switch 55 is located between the latch 53 and the reed switch 55. This allows for a further design where, when the latch 53 extends and engages with the groove 11, it forms a slope that pushes the magnetic element 12 upwards. Only then can it sense the reed switch 55 on the handle assembly 5, further preventing malfunctions such as the internal latch 53 not extending from affecting the judgment of the actual locking / unlocking status.

[0026] Furthermore, to ensure that the handle assembly 5 is not easily physically disassembled after engaging with the groove of the lock body 1, a fixing button 13 is provided at the end of the lock body 1 away from the rotating member 4. The fixing button 13 is used to engage with the end of the handle assembly 5. When the handle assembly 5 is pressed into the lock body 1, the fixing button 13 at the end away from the rotating member 4 can slide slightly towards the end of the handle assembly 5, thereby locking the protrusion at the end of the handle assembly 5 to further prevent the handle assembly 5 from automatically springing up. The handle assembly 5 itself is hinged to the rotating member 4 via a pivot, and a compression spring 57 is sleeved on the pivot. The compression spring 57 is used to keep the handle assembly 5 away from the groove on the lock body 1 in its natural state, that is, the handle assembly 5 will spring up after unlocking. At this time, the handle assembly 5 can drive the rotating member 4 to rotate, and the handle assembly 5 will not be blocked by the lock body 1, thereby achieving the purpose of unlocking the lever 31.

[0027] In addition, a dust cover 56 is rotatably connected above the smart chip 51 to prevent dust from affecting the smart chip 51 and the lock cylinder 52. The lower end of the dust cover 56 is a rotating part with markings on its surface indicating the opening method. After rotation, the positions of the smart chip 51 and the lock cylinder 52 are exposed. Overall, the length of the handle assembly 5 is [missing information - likely a percentage] of the length of the lock body 1. This length design ensures that the locking and unlocking movements of the handle assembly 5 are evenly stressed by the fixed lock body 1, making it less likely to be damaged by external forces.
