Abstract
Description
Technical Field
[0001] This utility model relates to the field of door lock technology, specifically to a multi-door lock mechanism for a grain warehouse. Background Technology
[0002] Grain warehouses are vital facilities for storing grain, and ensuring the quality and safety of this grain is crucial. In grain warehouse design, the door locking mechanism, as an important component of security, plays a vital role in preventing theft.
[0003] However, traditional grain warehouse door lock mechanisms are relatively simple in design, with only one lock. While this can prevent unauthorized unlocking to some extent, the lack of additional security measures makes them vulnerable to being broken through by force or tools. Furthermore, if the grain warehouse is breached, staff will not be able to detect it in time. These risks not only affect the security of the grain warehouse but also create difficulties for its management. Utility Model Content

[0039] Example
[0040] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment provides a multi-door lock mechanism for a grain warehouse, including a warehouse door 1, a first door lock unit 2, a second door lock unit 3, a touch detector 321, and a wireless communication module 322. The touch detector 321 can be an infrared sensor or a touch switch. The first door lock unit 2 includes a locking mechanism 21 disposed on the door panel 11 of the warehouse door 1 and a lock groove 22 for locking or unlocking with the locking mechanism 21. The lock groove 22 is disposed on the door frame 12 of the warehouse door 1. The second door lock unit 3 includes a cover 31, a mounting bracket 32 disposed on the door panel 11, and multiple lock heads 33 for connecting and locking the cover 31 to the door panel 11. The cover 31 is disposed on the mounting bracket 32 to cover or expose the locking mechanism 21. The touch detector 321 is disposed on the mounting bracket 32, and the monitoring end of the touch detector 321 is abutted against the cover 31. The wireless communication module 322 is electrically connected to the touch detector 321.
[0041] Specifically, the warehouse door 1 is equipped with a dual protection mechanism consisting of a first door lock unit 2 and a second door lock unit 3 to ensure the safety of the grain warehouse. The cover 31 of the second door lock unit 3 covers the locking mechanism 21. To open the warehouse door 1, the lock cylinder 33 must be unlocked first, allowing the cover 31 to be removed, exposing the first door lock unit 2, and then the locking mechanism 21 to be unlocked, thus opening the warehouse door 1. By implementing a dual door lock system, illegal intrusion can be effectively prevented, enhancing the anti-theft performance of the door lock mechanism.
[0042] Furthermore, when the cover 31 moves to expose the locking mechanism 21, the trigger detector 321 immediately triggers a signal, and the wireless communication module 322 transmits the signal to the control room, achieving real-time monitoring of the lock status of the warehouse door 1. This ensures that management personnel can promptly grasp the security status of the grain warehouse and effectively prevent potential risks. In the event of an abnormal intrusion, only the second door lock unit 3 is opened, while the first door lock unit 2 still provides secondary protection. Upon receiving the signal that the second door lock unit 3 has been opened, the control room can promptly activate the emergency plan, issue an alarm, and notify security personnel to quickly rush to the scene to ensure the safety of the grain warehouse.
[0043] like Figure 2 and Figure 4 As shown, in this embodiment, the mounting bracket 32 is provided with a slide rail 323, and the cover 31 is provided with a slider 313 that slides and engages with the slide rail 323; the cover 31 is provided with a plurality of first locking holes 311, and the mounting bracket 32 is provided with second locking holes 324 corresponding to the first locking holes 311.
[0044] Specifically, the cover 31 is slidably mounted on the mounting bracket 32. When the cover 31 slides upward, the locking mechanism 21 is exposed, thereby unlocking the first door lock unit 2 and opening the warehouse door 1. Since grain warehouses typically require two people to inspect them and single-person entry is not permitted, in a preferred embodiment, the cover 31 is provided with two first lock holes 311, and the mounting bracket 32 is provided with two corresponding second lock holes 324. Thus, the protection mechanism for the grain warehouse can adopt a two-person inspection mechanism, that is, two inspectors need to each hold the key to the corresponding lock hole and operate simultaneously to unlock the cover 31. By setting up a double-lock mechanism, it is convenient for each person to manage one lock, eliminating the risk of single-person entry and further enhancing the security and management rigor of the grain warehouse.
[0045] like Figure 1 and Figure 4 As shown, in this embodiment, a magnetic attractor 111 is provided on the door panel 11 of the warehouse door 1, and a magnetic block 312 that attracts the magnetic attractor 111 is provided at the end of the cover 31. When the cover 31 slides upward to expose the locking mechanism 21, the magnetic attractor 111 and the magnetic block 312 automatically attract each other, so that the cover 31 is stably positioned and prevents the cover 31 from sliding down after being released, so as to facilitate personnel to lock or unlock the first door lock unit 2.
[0046] In another alternative embodiment, the mounting frame 32 is provided with a rotating shaft (not shown in the figure), one end of the cover 31 is mounted on the rotating shaft, and the other end of the cover 31 is provided with a locking hole (not shown in the figure) for the lock head 33 to engage. That is, the cover 31 can be rotated around the rotating shaft to cover or expose the locking mechanism 21. Similarly, multiple locking holes are provided between the cover 31 and the mounting frame 32. Multiple inspection personnel are required to work together to ensure a rigorous unlocking process, further strengthening the security of the grain warehouse and improving management efficiency.
[0047] like Figure 3As shown, in this embodiment, the locking mechanism 21 includes a latch 211 and a drive shaft 212 that drives the latch 211 to move back and forth. A limiting groove 112 for the latch 211 to move is provided inside the door panel 11. One end of the drive shaft 212 passes through the door panel 11, forming an operating end for locking or unlocking the first door lock unit 2. A worm gear shaft section 2112 is provided on the rod of the latch 211, and a worm wheel 2121 that cooperates with the worm gear shaft section 2112 is provided at the other end of the drive shaft 212. A manual crank 4 is provided at one end of the drive shaft 212 for installation or removal.
[0048] When opening the compartment door 1, connect the manual crank handle 4 to the operating end of the drive shaft 212. Rotating the manual crank handle 4 drives the worm shaft section 2112 to rotate. The worm shaft section 2112 meshes with the worm wheel 2121, driving the latch 211 to move until it disengages from the lock groove 22 on the door frame 12, thus unlocking the compartment door 1. Conversely, rotating the manual crank handle 4 in the opposite direction moves the latch 211 to engage with the lock groove 22 on the door frame 12, thus locking the compartment door 1.
[0049] In addition, a linear bearing 2111 is provided between the latch 211 and the limiting groove 112, and a bearing 2122 is provided between the middle of the drive shaft 212 and the door panel 11. By providing linear bearings 2111 and 2122, friction and wear of various components are reduced, service life is extended, and operational smoothness is improved. The linear bearing 2111 ensures that the latch 211 moves smoothly in a straight line along the limiting groove 112, ensuring that the latch 211 and the locking groove 22 are precisely aligned and locked.
[0050] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
