Description

Technical Field

[0001] This utility model relates to the field of security door lock technology, specifically a security door lock for an energy efficiency control cabinet. Background Technology

[0002] Energy efficiency control cabinets play a vital role in industrial environments and some special locations. To ensure the safe and stable operation of the equipment inside the control cabinet and to prevent unauthorized personnel from operating it, safety door locks have become an essential protective device. With the development of technology, fingerprint recognition safety door locks have been widely used in the field of energy efficiency control cabinets due to their convenience and security. However, in humid environments, moisture becomes a key factor affecting the performance of fingerprint recognition security locks. On the one hand, moisture easily condenses on the surface of the fingerprint recognition module, leading to a decrease in recognition accuracy. Users often need to try multiple times to unlock successfully, which seriously affects the user experience. On the other hand, being in a humid environment for a long time will accelerate the aging of the fingerprint recognition module and related electronic components, greatly shortening the service life of the security lock. Existing technologies typically involve installing a movable cover in front of the security door lock to protect the fingerprint recognition module and reduce the impact of moisture. However, this approach has significant drawbacks. In humid environments, external factors (such as humid air and splashing water droplets) can easily cause water droplets to adhere to the cover surface when the user pushes it. When the user touches the fingerprint recognition module with wet fingers, it still significantly affects the recognition accuracy, failing to fundamentally solve the problem caused by humid environments. Therefore, a security door lock for an energy efficiency control cabinet is proposed to address the above issues. Utility Model Content

[0016] Please see Figure 1-6 This utility model provides a technical solution: A safety door lock for an energy efficiency control cabinet includes a fixing plate 1. A moisture-proof lock body assembly 2 is fixedly connected to the front end of the fixing plate 1. The moisture-proof lock body assembly 2 includes a lock body 21. A connecting groove 22 is provided in the middle of the front end of the lock body 21. An installation rod 23 is fixedly connected to the center of the inner side of the connecting groove 22. A spring 24 is sleeved on the outer side of the installation rod 23. A protective plate mechanism 25 is installed on the outer side of the spring 24. The protective plate mechanism 25 is rotatably connected to the lock body 21. An airbag cleaning mechanism 26 is installed on one side of the front end face of the lock body 21. An installation cavity 28 is provided at the bottom of the front end face of the lock body 21. The airbag cleaning mechanism 26 includes a first airbag 261. A second airbag 262 is fixedly connected to both sides of the first airbag 261. A first scraper 263 is fixedly connected to the middle of the front end of the first airbag 261. A second scraper 264 is fixedly connected to the middle of the front end of each of the second airbags 262.

[0017] As a further implementation of this solution, the protective plate mechanism 25 includes a circular protective plate 251. There is a gap between the back of the circular protective plate 251 and the front end face of the lock body 21. A sealing element 3 is fixedly connected to the side of the front end face of the lock body 21. An indicator groove 4 is provided on the side of the front end face of the circular protective plate 251 near the finger movement groove 252. A finger movement groove 252 is provided on the top of the circular protective plate 251. A connecting pipe 253 is fixedly connected to the center of the back of the circular protective plate 251. The outer side of the connecting pipe 253 is rotatably connected to the inner side of the connecting groove 22. The inner side of 53 is fixedly connected to the front end of the spring 24. The connecting tube 253 and the finger movement groove 252 are located on the same central axis. The bottom of the circular protective plate 251 is fixedly connected to the slotted placement seat 254. The slotted placement seat 254 and the finger movement groove 252 are arranged symmetrically about the connecting tube 253. The inner side of the slotted placement seat 254 is fixedly connected to the activated carbon block 255. The activated carbon block 255 can absorb moisture in the surrounding environment, reduce the humidity around the fingerprint recognition module 29 inside the lock body 21, and prevent the electronic components from short-circuiting or being damaged due to moisture. As a further implementation of this solution, positioning seats 256 are fixedly connected to both sides of the slotted placement seat 254. The two positioning seats 256 are arranged symmetrically from left to right. A support spring 257 is fixedly connected to the inner side of the positioning seat 256. A positioning rod 258 is fixedly connected to the front end of the support spring 257. The front end of the positioning rod 258 has an arc-shaped structure. The outer side of the positioning rod 258 is slidably connected to the inner side of the positioning seat 256. When the circular protective plate 251 is in its natural state, it plays a role in precise positioning, ensuring that the finger movement slot 252 is always directly above, which is convenient for user operation. At the same time, it also ensures that the circular protective plate 251 accurately protects the fingerprint recognition module 29. As a further implementation of this solution, a mounting groove 27 is provided at the front end of the lock body 21 near the first airbag 261. The vertical cross-section of the mounting groove 27 is fan-shaped. The axis of the mounting groove 27 is adapted to the axis of the mounting rod 23. The rear end face of the first airbag 261 is fixedly connected to the inner wall of the mounting groove 27. The number of first airbags 261 is set to several, and the several first airbags 261 are equidistantly arranged in an arc shape. The several first airbags 261 are connected by an air supply pipe 265, which allows the air pressure in each first airbag 261 to be balanced and transmitted to each other, thereby ensuring that the first scraper 263 has uniform force when scraping water off the fingers and improving the cleaning effect. As a further implementation of this solution, the inner side of the second airbag 262 is connected to the inner side of the first airbag 261. The second airbag 262 is shaped like a flat-topped cone, and the outer side of the second scraper 264 is shaped like an inclined structure, which can more effectively remove water from the fingerprint groove on the side of the finger. The second scraper 264 and the first scraper 263 work together to thoroughly clean the water on the finger and improve the success rate of fingerprint recognition. As a further implementation of this solution, a mounting cavity 28 is provided at the bottom of the front face of the lock body 21. The mounting cavity 28 and the mounting rod 23 are located on the same central axis. The slotted placement seat 254 is located in front of the mounting cavity 28. There is a gap between the outer side of the positioning seat 256 and the inner wall of the mounting cavity 28. The fingerprint recognition module 29 is fixedly connected to the bottom of the inner side of the mounting cavity 28. This arrangement can provide good protection, and when the circular protective plate 251 is rotated open, it can also facilitate the user to perform fingerprint recognition operation.

[0018] Workflow: The outer side of the lock body 21 has a circular structure. Since the mounting rod 23 is connected to the connecting tube 253 via a spring 24, and the connecting tube 253 is rotatably positioned inside the connecting groove 22, the finger movement groove 252 is naturally positioned directly above the mounting rod 23. At this time, the finger movement groove 252 is in its initial position. In humid environments, the circular protective plate 251 effectively protects the fingerprint recognition module 29 at the bottom of the lock body 21. Simultaneously, a slotted placement seat 254 is provided at the bottom of the back of the circular protective plate 251. The position of the slotted placement seat 254 corresponds to the position of the mounting cavity 28. The slotted placement seat 254 utilizes the inner side of its... The activated carbon block 255 absorbs moisture from the inside of the mounting cavity 28, further protecting the fingerprint recognition module 29. The positioning rod 258, elastically connected to the front end of the positioning seat 256, has arc-shaped structures at its front ends that abut against the sides of the mounting cavity 28, effectively positioning the circular protective plate 251. With the cooperation of the spring 24, the finger movement groove 252 remains directly above the user's finger when in its natural state. When the user is ready to unlock, they insert their finger into the finger movement groove 252 on the circular protective plate 251 and rotate the circular protective plate 251 clockwise through the finger movement groove 252. At this time, the positioning rod... 258 is affected by the rotational thrust of the circular protective plate 251, and retracts to the inside of the positioning seat 256. The circular protective plate 251 rotates around the connecting pipe 253 as the axis, and the spring 24 contracts to store elastic potential energy. The arrow end of the seal 3 points in the direction of rotation of the circular protective plate 251. During the rotation of the circular protective plate 251, the finger will fully contact the airbag cleaning mechanism 26 set on one side of the lock body 21. During this process, the first airbag 261 uses internal air pressure to make the first scraper 263 fully fit with the middle of the finger. The second airbag 262, which is set with flat-topped cones on both sides, allows the second scraper 264 to better fit the hand. The curved sides allow for the removal of water adhering to the fingerprint groove by several first scrapers 263 and several second scrapers 264 during rotation, thus cleaning the damp fingers. When the protective plate rotates to 180° and moves to the mounting cavity 28 area, the fingerprint recognition module 29 is fully exposed. The cleaned finger is pressed on the fingerprint recognition module 29 for recognition. If the fingerprint recognition is successful, the security door lock is unlocked, and the user can open the energy efficiency control cabinet. After successful unlocking, the finger is withdrawn, and the circular protective plate 251 automatically resets under the action of the spring 24, covering the fingerprint recognition module 29 again, waiting for the next unlocking operation.
