Description

Technical Field

[0001] This utility model relates to the technical field of tag-locking devices, specifically a centralized automatic tag-locking device. Background Technology

[0002] Tagging and locking are standardized safety control measures used in the field of industrial safety to prevent equipment from starting unexpectedly or releasing energy accidentally during equipment inspection, maintenance, or troubleshooting. The core of this method is to forcibly cut off the equipment's energy source and clearly indicate the warning status through a combination of "physical locking" and "warning tagging". This covers all potential energy sources of the equipment, including electrical energy, mechanical energy, hydraulic energy, pneumatic energy, thermal energy, and chemical energy, to avoid risks caused by the omission of a single energy source.

[0003] In the process of using electrical energy, when locking and tagging, the control switch is usually turned off and then locked. After locking, a tag is hung in the corresponding position (such as "Equipment under maintenance" or "Operation prohibited") to serve as a visual warning. However, in daily use, the tagging and locking device usually needs to be carried manually. During operation, there may be omissions such as "locking without tagging" or "tagging without locking". Also, the key is easy to lose after locking. Therefore, it is necessary to design a centralized automatic tagging and locking device with strong practicality. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0016] Please see Figure 1-4 The present invention provides a technical solution: a centralized automatic tagging and locking device, including a protective box 1, a control box 2 fixedly connected to the inner wall of the protective box 1, a control switch 3 provided on one side of the control box 2, the control box 2 can be connected to the power supply, and the control switch 3 can cut off the current; a locking box 4 fixedly connected to one side of the inner wall of the protective box 1, a drive motor 5 fixedly connected to the lower side of the inner wall of the locking box 4, and a drive screw 6 fixedly connected to the output end of the drive motor 5; A push plate 7 is threaded onto the drive screw 6. A locking block 8 is fixedly connected to one side of the push plate 7. An LED tag 9 is fixedly connected to one side of the locking block 8. An identification component 10 is provided on one side of the control box 2. A warning mechanism 11 is provided on one side of the protective box 1. A closed door 12 that cooperates with the warning mechanism 11 is rotatably connected to one side of the protective box 1.

[0017] Please see Figure 1 and Figure 3The identification component 10 includes a mounting port 101 on one side of the control box 2, a fingerprint reader 102 fixedly connected to the inner wall of the mounting port 101, a processor 103 disposed between the fingerprint reader 102 and the drive motor 5, and an electrical connection between the processor 103 and the LED tag 9. The processor 103 can be an existing technology of the STM32F103 series. The processor 103 is an industrial-grade microcontroller with a built-in storage unit for storing the engineer's fingerprint template, name, and contact number. The processor 103 is electrically connected to the fingerprint reader 102, the LED tag 9, and the drive motor 5 to realize fingerprint verification, information matching, and device drive control. After the fingerprint reader 102 inside the side mounting port 101 collects the operator's fingerprint information, it transmits it to the STM32F103 series industrial-grade microcontroller (processor 103) between the fingerprint reader 102 and the drive motor 5. The processor 103 retrieves the pre-stored engineer's fingerprint template, name, and contact number through its built-in storage unit to perform fingerprint verification and information matching. After successful verification, the processor 103, through its electrical cooperation with the drive motor 5 and the LED tag 9, respectively realizes the automatic locking action driven by the drive motor 5 and the synchronous display of warning information such as the engineer's name and contact number on the LED tag 9, thus completing the integrated control of fingerprint authorization, automatic locking, and information visualization.

[0018] Please see Figure 2 The warning mechanism 11 includes a hollow block 111 fixedly connected to one side of the protective box 1, a push-button switch 112 fixedly connected to one side of the inner wall of the hollow block 111, a spring piece 113 fixedly connected to the other side of the inner wall of the hollow block 111, a pressure block 114 fixedly connected to the spring piece 113 and slidably fitted to the inner wall of the hollow block 111, and a limiting plate 115 fixedly connected to one side of the pressure block 114 and cooperating with the closed door 12. The hollow block 111 on one side of the protective box 1 serves as the mounting carrier, and the spring piece 113 on the other side of its inner wall is connected to the pressure block 114, with the pressure block 114 slidably fitted. A limiting plate 115 is fixed to one end of the inner wall of the hollow block 111 to cooperate with the closed door 12. When the closed door 12 is closed, it squeezes the limiting plate 115, which drives the pressure block 114 to compress the spring piece 113. The reaction force of the spring piece 113 limits and fixes the closed door 12 through the pressure block 114 and the limiting plate 115 to prevent accidental opening. When the closed door 12 is opened, the squeezing force disappears, the spring piece 113 elastically resets and pushes the pressure block 114 to move to one side of the inner wall of the hollow block 111, thereby triggering the push switch 112 on the inner wall to realize the linkage control between the door state change and the switch trigger.

[0019] Please see Figure 1The upper side of the locking box 4 has a linkage port 18 that cooperates with the locking block 8. A dustproof cotton 13 is fixedly connected to one side of the inner wall of the linkage port 18. The dustproof cotton 13 fits against one side of the LED tag 9. The linkage port 18 on the upper side of the locking box 4 provides a telescopic channel for the locking block 8. When the drive mechanism drives the locking block 8 to perform locking / unlocking actions, the locking block 8 can smoothly extend or retract along the linkage port 18. At the same time, the dustproof cotton 13 fixed to one side of the inner wall of the linkage port 18 fits tightly against the LED tag 9 on one side of the locking block 8. Without affecting the synchronous movement of the LED tag 9 with the locking block 8, it effectively prevents external dust from entering the interior of the locking box 4, avoids dust from adhering to core components such as the drive motor 5 and the drive screw 6, and ensures the long-term stable operation of the drive mechanism inside the locking box 4.

[0020] Please see Figure 1 Two control components 14 are fixedly connected to one side of the locking box 4. The two control components 14 are electrically connected to the processor 103. When the fingerprint reader 102 recognizes the fingerprint, it can control the control components 14 to send corresponding signals to the processor 103, so that the processor 103 can control the drive motor 5 to unlock or lock.

[0021] Please see Figure 2 A signal generator 15 is fixedly connected to the upper side of the push switch 112. The signal generator 15 can be connected to the local area network. The signal generator 15 fixed to the upper side of the push switch 112 uses the trigger state of the push switch 112 as the signal source. When the closed door 12 is opened and the pressure block 114 squeezes the push switch 112, the push switch 112 triggers the signal generator 15 to start. The signal generator 15 transmits the door status change (opening) and maintenance start related signals of the device to the relevant terminals in the local area network (such as power supply control unit, field management platform) in real time through the local area network connection function, so as to realize remote synchronous notification of maintenance status.

[0022] Please see Figure 3 Two guide rods 16 are fixedly connected to the lower side of the inner wall of the locking box 4. The push plate 7 has a guide opening 17 that slides with the guide rods 16. The two guide rods 16 fixed to the lower side of the inner wall of the locking box 4 form a sliding fit structure with the guide opening 17 on the push plate 7. When the drive motor 5 drives the drive screw 6 to rotate, the guide rods 16 can accurately limit the rotational freedom of the push plate 7, converting the rotational motion of the drive screw 6 into a smooth linear motion of the push plate 7 along the direction of the guide rods 16, thereby driving the locking block 8 to extend and retract precisely, ensuring the stability and positioning accuracy of the locking action.

[0023] The implementation principle of this application is as follows: When in use, the operator authenticates the identity through the fingerprint reader 102 in the mounting port 101 on the control box 2. The fingerprint reader 102 transmits the verification signal to the built-in processor 103. The processor 103 simultaneously receives the status feedback of the two control components 14 (ensuring that the device circuit and mechanical structure are in a ready state). After the verification is successful and the control component 14 provides normal feedback, the device is triggered to perform a locking action. The processor 103 sends a drive signal to the drive motor 5. After the drive motor 5 starts, it drives the drive screw 6 at the output end to rotate. Since the push plate 7 is threadedly engaged with the drive screw 6, and the push plate 7 is sleeved on the two guide rods 16 on the lower side of the inner wall of the locking box 4 through the guide port 17, the guide rods 16 restrict the rotational freedom of the push plate 7, making it move smoothly in a straight line along the guide rods 16. The push plate 7 drives the locking block 8 on one side to move synchronously. The locking block 8 extends through the linkage port 18 on the upper side of the locking box 4, completing the physical locking of the target equipment control switch 3 and realizing the physical locking of the target equipment energy isolation switch. At the same time, the processor 103 sends a power signal to the LED tag 9. The LED tag 9 lights up and displays warning content (such as "Equipment under maintenance + Engineer + Mobile Number" "Operation prohibited + Equipment under maintenance + Engineer + Mobile Number"), realizing the synchronous linkage of "locking and tagging". The dustproof cotton 13 on the inner wall of the linkage port 18 is attached to one side of the LED tag 9, which can prevent dust from entering the interior of the locking box 4 and ensure the operational stability of the drive components. During routine maintenance, when the closed door 12 is closed, it presses against the limiting plate 115, causing the pressure block 114 to compress the spring 113. The reaction force of the spring 113 causes the pressure block 114 to restrict the closed door 12 through the limiting plate 115, preventing the closed door 12 from opening. During routine maintenance, once the closed door 12 is opened, it is no longer restricted by the limiting plate 115 and the pressure block 114. The spring 113 resets and pushes the pressure block 114 to press the push switch 112. The push switch 112 sends a signal feedback to the corresponding unit (such as the power supply section, which can remind personnel using power to know that maintenance is needed). Thus, opening the closed door 12 will automatically notify, avoiding situations where personnel forget to notify during maintenance, resulting in sudden power outages and data loss.
