Abstract
Description
Technical Field
[0001] This utility model relates to the field of electric lock technology, and more specifically, to an anti-pry type lock tongue linkage alarm device for electric locks. Background Technology
[0002] With the development of technology, electronic locks have been widely used in office buildings, residential communities, banks, warehouses and other places. Compared with traditional mechanical locks, electronic locks have brought great convenience to people's lives and work due to their convenient remote control and diverse unlocking methods. However, electronic locks still have many hidden dangers in terms of security.
[0003] Currently, many criminals use force to open electronic locks to commit theft or illegal intrusion. Existing electronic locks have significant deficiencies in anti-pry functionality. On the one hand, most electronic locks rely solely on the mechanical structure of the lock body to resist prying. When subjected to specialized tools or significant external force, the lock tongue can be easily pried open, failing to provide effective protection. On the other hand, even if the lock body is damaged, many electronic locks cannot promptly send alarm signals, causing security personnel to fail to detect intrusion in a timely manner, delaying response and posing a serious threat to the lives and property of users.
[0004] Furthermore, some existing alarm devices have poor linkage with electronic locks, failing to accurately detect changes in the bolt's state, resulting in alarm delays or false alarms, thus reducing system reliability. Therefore, we propose an anti-pry bolt linkage alarm device for electronic locks. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figures 1-4 This utility model provides a technical solution: an anti-pry type latch linkage alarm device for an electronically controlled lock, including a lock body 1 and a lock shell 10 disposed on the lock body 1. A vibration sensor 11 is disposed inside the lock shell 10, enabling the device to monitor the vibration of the lock body 1 caused by external prying in real time. A latch 12 is also slidably connected inside the lock shell 10. A latch 2 is disposed on the front side of the latch 12. An annular groove 121 is disposed inside the front side of the lock body 1. An optical displacement sensor 3 is disposed on the lock body 1. The optical displacement sensor 3 includes a receiver 30 and a light source 31 disposed in the annular groove 121. The optical displacement sensor 3 also includes a reflector 33 fixedly installed on the rear side wall of the latch 2. The receiver 30 and the reflector 33 are directly opposite each other. A control host 16 is disposed on the lock body 1. An alarm 162 is disposed on the control host 16, which can accurately measure the displacement of the latch 12. The combination of the two provides multi-dimensional data to the control host 16, enabling it to accurately determine whether the lock body 1 has been pryed, greatly improving the comprehensiveness and accuracy of the anti-pry monitoring of the device.
[0029] In this embodiment, a mounting base 32 is fixedly installed at the rear end of the receiver 30 and the light source 31. The mounting base 32 is fixedly installed on the rear side wall of the annular groove 121, making the installation of the key components of the optical displacement sensor 3 more stable.
[0030] Specifically, a through hole 13 is provided at the center of the rear side wall of the annular groove 121, along the length of the latch 12. The rear end of the through hole 13 is connected to the outside. A cylindrical rod 4 is provided inside the through hole 13, and a straight wire 41 is provided inside the through hole 13. One end of the straight wire 41 is fixedly installed on the fixing base 32, and the other end of the straight wire 41 is fixedly installed with a spiral wire 42. The spiral wire 42 is wrapped around the cylindrical rod 4. Even if the latch 12 pulls on the line during the sliding process, the spiral wire 42 can effectively buffer the line through its own expansion and contraction, ensuring the stable connection of the line and maintaining the continuous normal operation of the optical displacement sensor 3.
[0031] Furthermore, a fixing plate 40 is fixedly installed at the rear end of the cylindrical rod 4. The fixing plate 40 is fixedly installed inside the lock housing 10, which serves to support the normal use.
[0032] In addition, a rectangular frame 20 is fixedly installed on the latch 2. The rectangular frame 20 is fixedly installed on the external door frame by multiple fastening screws for normal installation operation.
[0033] It is worth noting that a display screen 161 is provided on the front side of the control host 16, which allows the operator to intuitively see the real-time status of the lock body 1, including the position of the bolt 12 and whether there are any abnormal alarms. The lock body 1 is also provided with a handle bar 14, and a handle 15 is fixedly installed at the end of the handle bar 14, which greatly facilitates the user's daily unlocking and locking operations, improving the security of the access control system while taking into account the ease of use.
[0034] It is worth noting that the vibration sensor 11 monitors the vibration of the lock body 1 in real time, and the optical displacement sensor 3 accurately measures the displacement change of the bolt 12. When the bolt 12 is subjected to abnormal external force or the displacement exceeds the normal range, the vibration sensor 11 and the optical displacement sensor 3 will immediately collect relevant data and transmit it to the control host 16. Once the control host 16 receives the abnormal signal from the vibration sensor 11 and the optical displacement sensor 3 monitoring the status of the bolt 12, it will quickly issue a command to activate the alarm 162 and emit a high-decibel alarm sound to deter criminals. The control host 16 adopts a high-performance microprocessor with built-in intelligent algorithms, which can analyze and process the data transmitted from the bolt 12 status monitoring in real time. By setting a reasonable threshold, it can accurately determine whether the bolt has been pried, and issue a corresponding command to the alarm 162 based on the judgment result. The entire device is powered by the power supply built into the lock body 1.
[0035] Finally, it should be noted that the vibration sensor 11, optical displacement sensor 3, control host 16, alarm 162, and display screen 161 involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. In the spare parts of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection methods should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.
[0036] When using the electric lock anti-pry type lock tongue linkage alarm device of this utility model, first fix the rectangular frame 20 on the lock buckle 2 to the door frame with fastening screws, assemble the lock body 1 in place, and ensure that the vibration sensor 11, optical displacement sensor 3 and other components are in normal condition.
[0037] In daily use, when criminals attempt to pick the lock, the lock body 1 vibrates abnormally and the bolt 12 moves beyond the normal range. The vibration sensor 11 and the optical displacement sensor 3 quickly collect data and transmit it to the control host 16. The control host 16 analyzes and processes this abnormal data. Once it is determined to be a lock picking attempt, it immediately sends a command to the alarm 162. The alarm 162 then emits a high-decibel alarm to deter criminals.
[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
