Abstract
Description
Technical Field
[0001] This utility model relates to the field of lock technology, and in particular to a lock with multiple unlocking methods and a trash can. Background Technology
[0002] In existing technologies, locks, as a key component of security, have evolved from traditional mechanical locks to electronic locks. Traditional mechanical locks, such as key locks, rely on the matching of physical keys to ensure security, but they are subject to the risk of lost or copied keys, and their operation is relatively inconvenient. With the development of technology, electronic locks, such as fingerprint locks and password locks, have gradually become more widespread. They improve security and convenience through electronic authentication systems, such as remote authorization and timed locking, greatly enriching the application scenarios of locks.
[0003] However, existing locks still face a series of technical problems. First, the dependence on a single mode is significant. Electronic locks are highly dependent on power supply; once the power is cut off or the circuit fails, they will completely fail and cannot provide security. While traditional mechanical locks are not affected by power, the risks of key management cannot be ignored. Second, there is a trade-off between security and convenience. Improving security often requires adding operational steps, thus sacrificing convenience. In addition, the single lock cylinder structure is easily exploited by technical unlocking or forced entry, reducing the overall security of the lock. In emergency escape scenarios, some electronic locks cannot respond quickly due to structural design issues and cannot meet the emergency mechanical opening requirements of fire regulations. Finally, traditional multi-lock parallel solutions require independent installation of electronic and mechanical locks, resulting in a bloated structure, complex maintenance, low system integration, and increased difficulty in troubleshooting.
[0004] Therefore, existing locks still need improvement in terms of reliability, security level, and adaptability to different scenarios. Utility Model Content
[0005] To address the problems existing in the prior art, this utility model provides a lock with multiple unlocking methods, comprising:
[0006] The lock body has an electromagnetic lock inside and a manual pin that passes through the lock body, and the electromagnetic lock and the manual pin are connected by a transmission.
[0007] The latch is located below the lock body and has a lock hole corresponding to the position of the manual latch.
[0008] Preferably, a conductive baffle is installed on the manual latch, and the electromagnetic lock is connected to the manual latch through the conductive baffle.
[0009] Preferably, the manual latch includes:
[0010] A handle that extends from top to bottom through the lock body;
[0011] A T-shaped head is located at the end of the handle.
[0012] Preferably, the T-shaped head is adapted to the shape of the keyhole.
[0013] Preferably, the handle is L-shaped.
[0014] Preferably, when the lock body and the latch are in the locked state, the T-shaped head is perpendicular to the length direction of the keyhole, and the handle is parallel to the length direction of the keyhole.
[0015] This utility model also provides a trash can, on which a lock as described above is installed;
[0016] The trash can is equipped with a latch of the lock on its body, and the trash can lid is equipped with a lock body of the lock.
[0017] Preferably, the bottom of the lock body is also provided with a limiting stud, which corresponds to the position of the limiting hole opened on the barrel body.
[0018] The above technical solution has the following advantages or beneficial effects:
[0019] 1. Dual protection enhances lock reliability: This lock combines the intelligent control of an electromagnetic lock with the mechanical backup of a manual bolt, achieving redundant backup for both electric drive and mechanical operation. This design avoids the problem of dependence on a single mode, ensuring that the lock provides security protection under any circumstances (such as power failure or electronic malfunction), greatly improving the reliability of the lock.
[0020] 2. Balancing Security and Convenience: The intelligent control function of the electromagnetic lock enhances its convenience, allowing users to easily unlock it in multiple ways. Meanwhile, the direct physical operation of the manual bolt provides a means of rapid intervention in emergencies, meeting the needs of high-level access management and emergency escape requirements, thus achieving a perfect balance between security and convenience.
[0021] 3. Optimized structure and reduced maintenance costs: This lock features an integrated transmission structure design that tightly combines the electromagnetic lock and manual bolt, reducing its size and complexity, making it suitable for installation in confined spaces. This design not only improves the lock's aesthetics but also reduces the difficulty of troubleshooting faults caused by the independent operation of multiple systems, thus lowering maintenance costs.

[0026] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. The present invention is not limited to this embodiment; other embodiments that conform to the spirit of the present invention may also fall within its scope.
[0027] In a preferred embodiment of this utility model, based on the above-mentioned problems existing in the prior art, a lock with multiple unlocking methods is now provided, such as... Figures 1-2 As shown, it includes:
[0028] Lock body 1, the lock body 1 is equipped with an electromagnetic lock 11 and a manual pin 12 that passes through the lock body 1, and the electromagnetic lock 11 and the manual pin 12 are connected by transmission.
[0029] The latch 2 is located below the lock body 1 and has a lock hole 21 corresponding to the position of the manual bolt 12.
[0030] Specifically, the lock of this invention incorporates both an electromagnetic lock 11 and a manual bolt 12. The electromagnetic lock 11 can be electrically unlocked using various methods such as QR code, Bluetooth, and NFC (Near Field Communication). It can also be manually opened by rotating the manual bolt 12. This design achieves both intelligent control of the electromagnetic lock 11 and retains the mechanical unlocking method of the manual bolt 12, providing redundancy between electric drive and mechanical operation. This design avoids dependence on a single mode, ensuring the lock provides security protection under any circumstances (such as power outages or electronic malfunctions), greatly improving the lock's reliability.
[0031] In a preferred embodiment of the present invention, a conductive baffle 13 is installed on the manual latch 12, and the electromagnetic lock 11 is connected to the manual latch 12 through the conductive baffle 13.
[0032] Specifically, in this embodiment, a conductive baffle 13 is provided. In the event of a malfunction of the electromagnetic lock 11, the manual latch 12 can be rotated to activate the latch. Figure 1 The manual latch 12 rotates 90 degrees clockwise (X) to becomeFigure 2 The state in, Figure 1 The middle position indicates that the lock is in the locked state. Figure 2 (In the unlocked state), the conductive baffle 13 pushes the bolt of the electromagnetic lock 11 in the Y direction ( Figure 3 As described above, the retraction enables manual unlocking, constructing a dual redundancy structure of "electric control priority + mechanical emergency". When the electromagnetic lock control system fails (such as power failure or circuit failure), emergency unlocking can still be completed through the mechanical transmission path, significantly improving system availability.
[0033] Electromagnetic lock 11 can be electrically unlocked using various methods such as QR code, Bluetooth, and NFC (Near Field Communication). During unlocking, the bolt can move in the Y direction (…). Figure 3 If it slides freely on the surface (as described in the text), then the conductive baffle 13 can rotate freely.
[0034] When the electromagnetic lock 11 is locked, the bolt extends outward toward the transmission baffle 13, pushing the transmission baffle 13 to rotate counterclockwise, thereby driving... Figure 2 The manual latch 12 rotates 90 degrees counterclockwise (the opposite of clockwise X) to become Figure 1 The state in, Figure 1 The middle position indicates that the lock is in the locked state. Figure 2 The lock is in the unlocked state, and the bolt is locked and cannot be slid, thus completing the locking process.
[0035] This lock features an integrated transmission structure design that tightly combines the electromagnetic lock and the manual bolt, reducing the lock's size and complexity and making it suitable for installation in confined spaces.
[0036] In a preferred embodiment of this utility model, such as Figure 2 As shown, the manual latch 12 includes:
[0037] Handle 121, which runs from top to bottom through lock body 1;
[0038] T-shaped head 122 is located at the end of handle 121.
[0039] In a preferred embodiment of the present invention, the T-shaped head 122 is adapted to the shape of the keyhole 21.
[0040] In a preferred embodiment of this utility model, the handle 121 is L-shaped.
[0041] Specifically, as shown in the figure, the handle 121 of the manual latch is L-shaped, and the bending angle has been optimized through simulation (for example, bending radius R = 8mm, bending angle 115°), which conforms to the human hand grip curve and can significantly reduce the effort required when manually unlocking.
[0042] The T-head 122 provides locking in two directions and forms a unique matching relationship with the keyhole 21. Topology optimization eliminates the possibility of reverse insertion and reduces the error rate.
[0043] In a preferred embodiment of the present invention, when the lock body 1 and the latch 2 are in a locked state, the T-shaped head 122 is perpendicular to the length direction of the lock hole 21, and the handle 121 is parallel to the length direction of the lock hole 21.
[0044] Specifically, in the locked state, the handle 121 is arranged parallel to the lock hole 21 (and also parallel to the edge of the barrel) to form visual-tactile consistency, and the operator can confirm the current locking state by the orientation of the handle.
[0045] This utility model also provides a trash can, such as Figures 3-4 As shown, the trash can is equipped with the locks described above;
[0046] The trash can body 100 is equipped with a lock buckle 2, and the trash can lid 200 is equipped with a lock body 1.
[0047] In a preferred embodiment of the present invention, the bottom of the lock body 1 is further provided with a limiting stud 14, which corresponds to the position of the limiting hole opened on the barrel body.
[0048] Specifically, in this embodiment, the lock body is installed on the body 100 of the trash can by means of the limiting stud 14 to ensure the stability of the installation.
[0049] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made using the content of this specification and illustrations should be included within the protection scope of the present utility model.
