[0019] (III) Beneficial effects

[0020] Compared with the prior art, the present invention provides a mechanical password emergency lock cylinder intelligent password box, which has the following beneficial effects:

[0021] The mechanical password emergency lock cylinder intelligent password box has a bearing assembly as the main frame part of the password box. The bearing cavity of the middle frame body provides a stable placement space for the internal components and stored items. The design with an opening on the front is convenient for putting in and taking out items. The middle frame sealing ring set in the bearing cavity plays a key waterproof role. The storage slot on the front of the lower part is used to place items. The sealing ring effectively isolates the storage area from the outside to prevent liquid from entering from the outside and causing damage to the stored items. Even if the password box is placed outdoors and may be exposed to rain, water stains, etc., the safety of the internal items can be guaranteed, solving the problem of the lack of waterproofing in the storage area of ​​traditional password boxes;

[0022] The unlocking component provides an emergency unlocking method for the password box, and also has good anti-theft and anti-misoperation characteristics. When encountering special situations such as electronic failure (such as battery failure, electronic component damage, etc.) or forgetting the regular password, the password box can be opened by operating the unlocking component.

[0023] The password lock body is arranged on one side of the upper cover body, and the password lock core inside it cooperates with the retaining ring, the plug rod and other components to form a unique unlocking transmission structure. The password lock core passes through the password lock body and is plugged into the retaining ring. One end of the plug rod passes through the retaining ring and is connected to the inclined block in the lock body cavity. When the correct mechanical password is entered on the password lock core, the password lock core will produce a corresponding displacement (for example, the internal structure is linked by rotation and other actions). Since a conical surface is provided on the end close to the baffle, it is adapted to the conical groove on the retaining ring, which will push the retaining ring and the plug rod to move. The plug rod drives the inclined block to overcome the elastic force of the reset spring and move in the lock body cavity. The inclined block cooperates with the notch on the main tongue body to retract the main tongue body, thereby realizing emergency unlocking. This emergency unlocking method of mechanical password does not require carrying an additional key, which solves the problem that the spare unlocking port of the traditional mechanical lock needs to carry a key at all times and has poor anti-theft performance, and improves the convenience and safety of use.

[0024] The combination lock body and the insertion rod are arranged in the groove enclosed by the flange, and a friction groove adapted to the driving end of the combination lock body is arranged on the side of the sealing gasket close to the inner side of the groove. On the one hand, the groove plays a certain hiding and protection role for the combination lock body and other components. On the other hand, the friction groove can increase the friction between the finger and the driving end of the combination lock body, which makes it convenient to operate the combination lock body for password input while preventing others from accidentally driving the combination wheel of the combination lock body, further enhancing the anti-theft performance and accuracy of use of the combination box.

[0036] The bearing cavity of the middle frame body 1 is the supporting space for the internal structure of the entire password box and the storage space for items. Its front opening is convenient for users to put items in or take out items from the storage slot. The middle frame sealing ring 2 in the bearing cavity is a key structure to ensure the waterproofness of the storage area. Through its own elasticity and sealing characteristics, it separates the storage slot from the external environment. Whether the password box is outdoors and encounters rain or other liquid environments, it is difficult for liquid to break through the sealing ring and enter the storage slot, thereby ensuring that the internal items are not corroded by water, effectively solving the problem of the lack of waterproofness in the storage area of ​​traditional password boxes;

[0037] The auxiliary groove on the back of the middle frame sealing ring 2 is used to store the lock hook control component, making its layout more reasonable and compact. The lock hook body 3 is U-shaped, and the two free ends pass through the middle frame body 1 and are connected to the lock hook control component. The lock hook body 3 can be hung on other equipment through the lock hook control component;

[0038] The hinge seat 4 below the middle frame body 1 provides a rotation fulcrum for the opening and closing of the upper cover assembly, so that the upper cover can rotate smoothly around it. The rainproof cover 33 set on the middle frame body 1 is adapted to the lock hook body 3. When the password box is in an environment where it may be exposed to rain, such as outdoors, the rainproof cover 33 can prevent rain from entering the password box along the lock hook body 3, further enhancing the overall waterproof effect. The conical blocks 34 and the card slot structure at the two free ends of the lock hook body 3 help it to accurately connect and reliably transmit with the lock hook control assembly, ensure accurate and stable movement of the lock hook, and enhance the locking effect when closed;

[0039] The closing assembly includes an upper cover body 5, a power supply assembly, a main board 6, a controller 7 and a lock body assembly. The lower part of the upper cover body 5 is hinged to the hinge seat 4. The back side of the upper cover body 5 is adapted to the bearing cavity. The back side of the upper cover body 5 is provided with a mounting cavity. The back side of the upper cover body 5 is provided with a power supply assembly that closes the mounting cavity. The main board 6 is also provided in the mounting cavity. The upper cover body 5 is embedded with a controller 7 that is electrically connected to the main board 6. The main board 6 is provided between the controller 7 and the power supply assembly.

[0040] The upper cover body 5 is hinged to the hinge seat 4 of the bearing assembly at the bottom to achieve opening and closing movement around the hinge point, which is convenient for users to operate the password box to store or take out items. The installation cavity on the back of the upper cover body 5 is used to place the motherboard 6, and the L-shaped power supply assembly is used to close the installation cavity, which not only protects the internal electronic components from external dust, collisions, etc., but also makes the appearance neater;

[0041] The controller 7 embedded in the upper cover body 5 and electrically connected to the main board 6 is the interface for the user to perform regular unlocking operations. The user enters the password and other information in a preset manner on the controller 7, and the controller 7 transmits the relevant instructions to the main board 6. The main board 6 is the core control component, located between the controller 7 and the power supply component. After receiving the signal from the controller 7, it adjusts the power supply of the power supply component according to the built-in control logic, and sends control instructions to the drive motor 10 and other components in the lock body component to coordinate the work of various electronic components to achieve normal unlocking, locking and other functional operations of the password box;

[0042] The flanges 24 on the left and right sides of the upper cover body 5 cooperate with the corresponding notches on the middle frame body 1. When the password box is closed, the flanges 24 are embedded in the notches, increasing the contact area between the two, improving the overall sealing, preventing external liquids and dust from entering the password box from the side gaps, and jointly ensuring the stability of the internal environment with the middle frame sealing ring 2;

[0043] In this embodiment, the power supply component is L-shaped, and a lock body component connected to the main board 6 is also provided on the front of the upper part of the power supply component. The lock body component includes a lock body upper cover 8, a lock body lower cover 9, a drive motor 10, a main tongue body 11, a lock core shaft 12, a main tongue spring 13, a secondary tongue body 14 and a secondary tongue spring 15. The back side of the lock body upper cover 8 is connected to the power supply component, the lock body lower cover 9 and the lock body upper cover 8 are plugged together to form a lock body cavity, the upper and lower ends of the main tongue spring 13 are respectively connected to the bottom wall of the lock body cavity and the main tongue body 11, and a drive motor 10 connected to the main tongue body 11 is also provided above the lock body cavity.

[0044] The drive motor 10 serves as a power source, and the lock core shaft 12 with an eccentric shaft at its output end plays a key unlocking driving role. When the user enters the correct password through the controller 7 and performs conventional unlocking operations, the main board 6 receives the correct signal and sends a command to the drive motor 10, and the drive motor 10 starts to operate, driving the lock core shaft 12 to rotate. The lock core shaft 12 contacts and cooperates with the driving groove at one end of the main tongue body 11. As it rotates, it applies an external force to the main tongue body 11, causing the main tongue body 11 to overcome the elastic force of the main tongue spring 13 and retract downward, thus disengaging from the clamping state with the clamping block 16.

[0045] At the same time, the upper and lower ends of the auxiliary tongue spring 15 are respectively connected to the auxiliary tongue body 14 and the housing of the driving motor 10. The auxiliary tongue body 14 also passes through the through hole and is engaged with the clamping block 16, and together with the main tongue body 11, a double locking mechanism is formed. The auxiliary tongue body 14 is provided with a chamfer. When the main tongue body 11 shrinks, the upper cover body 5 is subjected to an external force, and the chamfer of the auxiliary tongue body 14 can squeeze the auxiliary tongue spring 15 under the pressure of the clamping block 16.
