Description

Technical Field

[0001] This utility model relates to the field of safe manufacturing technology, specifically to an emergency clutch opening structure for a safe. Background Technology

[0002] Safes are generally used to store valuables such as cash, gold, and jewelry. Traditional safes mostly use mechanical locks, but with the development of electronic locks (fingerprint locks, combination locks, etc.), some safes on the market now use electronic locks for unlocking.

[0003] These safes with electronic locks are mainly divided into two categories. One type combines electromagnetic locks and mechanical locks. The electromagnetic lock restricts the movement of the locking rod assembly, and fingerprints or passwords are used to unlock the electromagnetic lock, thereby eliminating the restriction on the movement of the locking rod assembly. The handle then drives the locking rod assembly to unlock the safe. In essence, the mechanical lock is still used to lock the safe. In the event of a power outage, the electromagnetic lock of this type of safe can be easily opened, and once the electromagnetic lock is opened, the safe door can be opened, resulting in poor security. Another type uses an electronic lock to control a motor, which in turn drives the movement of a locking rod assembly to unlock the safe. These safes typically include an emergency unlocking mechanism for special situations (battery replacement, maintenance, etc.). For example, patent application CN120625988A, entitled "A High-Reliability Safe Locking Component and Safe," discloses a safe structure including a drive motor and a bolt assembly; it also includes a mechanical lock assembly for providing emergency unlocking functionality. The mechanical lock assembly includes an emergency lock body, a transmission rod assembly, and a motor mounting plate. One end of the transmission rod assembly is connected to the motor mounting plate, and when the emergency lock body is in motion, it transmits power to the motor mounting plate, causing the motor mounting plate to move laterally. However, this emergency unlocking structure lacks protective measures; the emergency lock can be opened using a master key, mechanical unlocking, etc., thereby opening the safe door and affecting its security. Therefore, its structure needs further improvement. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned deficiencies and to disclose to the public a safe emergency clutch opening structure with reasonable structure and strong security.

[0005] The technical solution of this utility model is implemented as follows: An emergency clutch opening structure for a safe includes a door, a horizontally movable main lock rod mounting plate on the door, an electromagnetic lock assembly on the door, a latch on the electromagnetic lock assembly, a protrusion on the main lock rod mounting plate that engages with the latch, and an electromagnetic lock hole on the door corresponding to the electromagnetic lock assembly. An emergency mechanical lock is mounted on the main lock rod mounting plate, the emergency mechanical lock including a lock body with a limiting block hinged to it, the limiting block engaging with the main lock rod mounting plate, an emergency lock hole on the door corresponding to the limiting block, and a lever that engages with the main lock rod mounting plate. The lever has a non-circular cross-section connector positioned opposite the emergency lock hole.

[0006] Further optimization measures for this technical solution are as follows: As an improvement, the electromagnetic lock assembly includes a lock cylinder and a lock head that are linked together. The lock tongue is disposed on the lock head, a lock cylinder rod is disposed inside the lock cylinder, and a lock head rod is disposed on the lock head. A linkage rod is disposed between the lock cylinder rod and the lock head rod, and the end of the lock head rod away from the linkage rod is connected to the lock tongue. The electromagnetic lock assembly adopts a separate structure for the lock cylinder and the lock head, which makes the structure more stable, reliable, and lower in cost.

[0007] As an improvement, a blocking component is connected to the end of the lock cylinder rod away from the linkage rod. The upper part of the blocking component blocks the emergency lock hole when the electromagnetic lock assembly is locked. When the blocking component blocks the emergency lock hole, the emergency key cannot be inserted into the emergency lock hole, further ensuring that the emergency mechanical lock can only be opened after the electromagnetic lock assembly is opened.

[0008] As an improvement, the cabinet door is equipped with a motor that is signal-connected to the unlocking device. The motor drives the main locking rod mounting plate. A screw is connected to the motor. A screw seat is mounted on the main locking rod mounting plate. The screw is screwed to the screw seat. The limiting block abuts against the screw seat. A sliding groove is provided on the main locking rod mounting plate at the position corresponding to the screw seat.

[0009] As an improvement, a guide groove is provided horizontally on the main lock rod mounting plate, and a guide post is provided on the cabinet door, with the guide post placed in the corresponding guide groove.

[0010] As an improvement, a limit switch is provided on the cabinet door, and a protrusion that cooperates with the limit switch is provided on the main locking rod mounting plate. The cooperation between the limit switch and the protrusion limits the travel of the main locking rod mounting plate.

[0011] As an improvement, the electromagnetic lock assembly is provided with a first outer cover, and the main lock rod mounting plate is provided with a second outer cover. The outer cover can protect the internal parts and also block some dust, which helps to extend the service life.

[0012] As an improvement, the unlocking device can be a fingerprint device or a password device.

[0013] As an improvement, the motor is a stepper motor.

[0014] The advantages of this utility model compared with the prior art are: This utility model discloses an emergency clutch opening structure for a safe. The structure is rationally designed and includes an electromagnetic lock assembly and an emergency mechanical lock. For emergency unlocking, the electromagnetic lock must first be opened, causing the latch to retract and release its obstruction of the main lock rod mounting plate. Then, the emergency mechanical lock is opened in two steps. After the emergency key is inserted into the emergency lock hole, it pushes the limiting block inward, releasing the obstruction between the limiting block and the main lock rod mounting plate. Only then can the lever be rotated, causing the main lock rod mounting plate to move and unlock the safe. This structure significantly improves the safe's resistance to technical opening, further enhancing its security. Attached Figure Description

[0020] like Figures 1 to 7As shown, an emergency clutch opening structure for a safe includes a door 1, a horizontally movable main lock rod mounting plate 4 on the door 1, an electromagnetic lock assembly 5 on the door 1, a latch 5a on the electromagnetic lock assembly 5, a protrusion 41 on the main lock rod mounting plate 4 that cooperates with the latch 5a, and an electromagnetic lock hole 1a on the door 1 at a position corresponding to the electromagnetic lock assembly 5. An emergency mechanical lock 6 is also provided on the main lock rod mounting plate 4, the emergency mechanical lock 6 including a lock body 61, a limiting block 62 hinged to the lock body 61, the limiting block 62 engaging with the main lock rod mounting plate 4, an emergency lock hole 1b on the door 1 at a position corresponding to the limiting block 62, and a lever 63 cooperating with the main lock rod mounting plate 4. A non-circular cross-section connector 64 is provided on the lever 63 facing the emergency lock hole 1b.

[0021] In this embodiment, the inner cross-section of the connector 64 is hexagonal, allowing a hexagonal wrench to be used as an emergency key for easy operation by maintenance workers. Main locking rods 44 are spaced apart on the main locking rod mounting plate 4.

[0022] The electromagnetic lock assembly 5 includes a lock cylinder 51 and a lock head 52 that are linked together. The lock tongue 5a is disposed on the lock head 52. The lock cylinder 51 is provided with a lock cylinder rod 51a. The lock head 52 is provided with a lock head rod 52a. A linkage rod 53 is provided between the lock cylinder rod 51a and the lock head rod 52a. The end of the lock head rod 52a away from the linkage rod 53 is connected to the lock tongue 5a.

[0023] The lock cylinder rod 51a has a blocking member 54 connected to the end away from the linkage rod 53. The upper part of the blocking member 54 blocks the emergency lock hole 1b when the electromagnetic lock assembly 5 is locked. When the blocking member 54 blocks the emergency lock hole 1b, the emergency key cannot be inserted into the emergency lock hole 1b, further ensuring that the emergency key can only be inserted into the emergency lock hole 1b and open the emergency mechanical lock after the electromagnetic lock assembly 5 is opened.

[0024] The cabinet door 1 is equipped with a motor 3 that is signal-connected to the unlocking device 2. The motor 3 drives the main locking rod mounting plate 4. A screw 31 is connected to the motor 3. A screw seat 42 is mounted on the main locking rod mounting plate 4. The screw 31 is screwed into the screw seat 42. The limiting block 62 abuts against the screw seat 42. A sliding groove 4a is provided on the main locking rod mounting plate 4 at the position corresponding to the screw seat 42. By using the protruding screw seat 42 to cooperate with the limiting block 62, the screw seat 42 can perform two functions, making the structure simpler and more compact.

[0025] The main locking rod mounting plate 4 is provided with a guide groove 4b in the horizontal direction, and the cabinet door 1 is provided with a guide post 11, which is placed in the corresponding guide groove 4b. The cooperation between the guide groove 4b and the guide post 11 allows the main locking rod mounting plate 4 to move in a set horizontal direction.

[0026] The cabinet door 1 is equipped with a limit switch 12, and the main locking rod mounting plate 4 is equipped with a protrusion 43 that cooperates with the limit switch 12. The limit switch 12 is located on both sides of the protrusion 43. Through the cooperation between the limit switch 12 and the protrusion 43, the travel of the main locking rod mounting plate 4 is limited. When the protrusion 43 touches the limit switch 12, a control signal is sent to stop the motor 3 from working.

[0027] The electromagnetic lock assembly 5 is provided with a first outer cover 71, and the main lock rod mounting plate 4 is provided with a second outer cover 72. The outer covers enclose the electromagnetic lock assembly 5, which can protect the internal components and block some dust, thus improving its service life.

[0028] In this embodiment, the unlocking device 2 is a fingerprint device, but it can also be a password device. As an extension, Internet of Things (IoT) technology can be used, employing a mobile app as the unlocking device 2.

[0029] The motor 3 is preferably a stepper motor. Using a stepper motor as the power source results in more stable operation and more precise control.

[0030] Working principle: This utility model discloses an emergency clutch opening structure for a safe, which includes an electromagnetic lock assembly 5 and an emergency mechanical lock 6. In an emergency, the electromagnetic lock must be opened first, and then the emergency mechanical lock 6 can be opened.

[0031] The specific unlocking method is as follows: First, insert the electromagnetic lock key (the mechanical key used in emergency situations) into the electromagnetic lock hole 1a. Turn the electromagnetic lock key, causing the lock cylinder rod 51a of the lock cylinder 51 to move downwards. The lock cylinder rod 51a, through the linkage rod 53, causes the lock head rod 52a of the lock head 52 to move downwards, thereby retracting the bolt 5a and eliminating the obstruction of the bolt 5a to the protrusion 41 on the main lock rod mounting plate 4. As the lock cylinder rod 51a moves downwards, it also causes the blocking member 54 to move downwards. At this point, the emergency key can be inserted into the emergency lock hole 1b.

[0032] The emergency mechanical lock 6 operates in two steps. First, as the emergency key is inserted into the emergency lock hole 1b, the key pushes the limiting block 62 inward, disengaging it from the screw seat 42 and releasing its obstruction. Then, the emergency key is turned, causing the lever 63 to rotate. The lever 63 then moves the main lock rod mounting plate 4 (the screw seat 42 moves relative to the main lock rod mounting plate 4 within the slide groove 4a), thus completing manual unlocking to meet emergency unlocking needs. This safe uses a handle-less structure, requiring an emergency key for unlocking, further improving its ease of installation.

[0033] 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 based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
