In a traditional anti-misoperation management machine key box, the locking tongue structure of the lock is fixed. When facing situations such as box deformation and installation deviation, it is extremely easy to cause jamming, resulting in abnormal switching. Summary of the Invention
[0003] To solve the above technical problems, the present application proposes a lock and an anti-misoperation management machine key box applying the same.
[0004] The technical solution for achieving the purpose of the present application is as follows:
[0005] In a first aspect, the present application provides a lock, which includes:
[0006] A lock core whose length extends along a first direction, connected to a grip that can rotate horizontally to form a linkage structure;
[0007] A locking tongue, including a locking tongue body and a locking tongue force buffering mechanism. The locking tongue body is plate-shaped and the plate length extends along a second direction. The locking tongue force buffering mechanism is arranged on the locking tongue body and connected to the lock core, wherein the second direction is perpendicular to the first direction;
[0008] A locking tongue rotation amplitude regulating component for regulating the rotation amplitude of the locking tongue, including a locking tongue hook part and a driving mechanism connected to the locking tongue hook part and driving the locking tongue hook part to move;
[0009] When the grip rotates horizontally to the lock in the locked state, the locking tongue body is locked and buckled with the frame of the key box by rotating through the lock core. At this time, the locking tongue force buffering mechanism serves as a force transmission and buffering structure for the locking tongue body to contact and receive force with the frame of the key box.
[0010] In some embodiments of the first aspect, the plate body of the locking tongue body has a preparation groove extending along the second direction and configured with the locking tongue force buffering mechanism.
[0011] In some embodiments of the first aspect, the locking tongue force buffering mechanism includes: a positioning thimble and a spring part. Both the positioning thimble and the spring part are arranged in the preparation groove of the locking tongue body and both extend along the second direction, and both the positioning thimble and the spring part are connected to the bottom of the lock core.
[0012] In certain embodiments of the first aspect, the tongue hook portion includes:
[0013] A first horizontal plate portion;
[0014] A second horizontal plate portion having a tooth groove extending along the length on one side wall, the length of the first horizontal plate portion being less than the length of the second horizontal plate portion, and the first horizontal plate portion being located directly below the second horizontal plate portion; and
[0015] A connecting portion connecting the first horizontal plate portion and the second horizontal plate portion;
[0016] The first horizontal plate portion, the second horizontal plate portion, and the connecting portion form a card slot portion adapted to the tongue body, and the tongue body is located between the card slot portion and the driving mechanism.
[0017] In certain embodiments of the first aspect, the driving mechanism includes a driving motor and a gear set connected to the driving motor, and the gear set meshes with the second horizontal plate portion;
[0018] The card slot portion is driven by the driving mechanism to maintain linear motion.
[0019] In a second aspect, the present application proposes an anti-error management machine key box, which includes the lock according to any one of the first aspect. The anti-error management machine key box further includes: a housing, a handle, a battery, a control main board, and an identification part. The handle is horizontally rotatably provided on the front portion of the housing. The lock, the battery, and the control main board are all provided inside the housing. At least one human-computer interaction part of the identification part is provided on the front portion of the housing. The battery, the identification part, and the driving mechanism are all electrically connected to the control main board.

[0022] Compared with the prior art, the significant advantages of the present application are:
[0023] 1. A tongue receiving buffer mechanism is provided on the tongue body of the present application. This tongue receiving buffer mechanism is connected to the lock core. When the tongue body enters or exits the lock catch at the border of the key box, the tongue receiving buffer mechanism undergoes a small-range elastic deformation under the stressed state, playing a role in absorbing the stress of the entire tongue and compensating for displacement. Even in the case where the key box has slight structural deformation or installation position deviation due to manufacturing errors or long-term use, the tongue can still be smoothly inserted into or withdrawn from the lock catch, effectively avoiding problems such as jamming or structural damage, and improving the success rate of locking or unlocking the lock and the usage stability.
[0024] 2. By setting a tongue rotation amplitude regulating component in the present application, the rotation amplitude (angle) during the movement of the tongue is restricted and guided, thereby affecting the opening and closing of the lock.
[0025] 3. When the grip drives the lock core to rotate and the tongue enters the locked state through the tongue body and the tongue receiving buffer mechanism, during the meshing process of the tongue and the lock catch, since the tongue body is stressed first and then gradually transmitted to the lock core through the tongue receiving buffer mechanism, it effectively reduces the bearing force of the lock core bearing, alleviates the stress concentration of the lock core structure, extends the mechanical life of the connecting components of the lock core and the tongue, and maintains the operation smoothness and structural stability during the long-term use of the lock body.
[0026] 4. The grip of the present application is arranged on the front part of the key box and forms a linkage structure with the lock core. The user can complete the insertion and extraction of the tongue by horizontally rotating the grip. Compared with the traditional vertical or knob-type structure, the horizontal rotation method conforms to the ergonomic operation habit, the operation is intuitive and simple, and the force transmission path is smooth. Especially in the key box of the anti-misoperation management machine with limited space, it improves the convenience and accuracy of single-handed operation, reduces the probability of misoperation, and enhances the practical usability of the on-site anti-misoperation system.

Detailed implementation manners
[0030] In one or more embodiments of the present application, a lock is mentioned. This lock can be applied to the key box of the anti-error management machine, solving the problem that the lock tongue structure of the lock in the traditional anti-error management machine key box is fixed, and it is extremely easy to cause jamming and abnormal switching when facing situations such as box deformation and installation deviation.
[0031] As Figure 1 — Figure 2 As shown, the present application proposes a key box for an anti-error management machine, which includes a housing 10, a battery, a control main board 20, an identification part 30, a grip 40 and a lock 50. The grip 40 is horizontally rotatably arranged on the front part of the housing 10. The lock 50, the battery and the control main board 20 are all arranged in the housing 10. The battery (not shown in the figure), the identification part 30 and the lock 50 are all electrically connected to the control main board 20. The control of the associated object by the control main board 20 is all prior art. The control part of the key box for the anti-error management machine more reflects the automation and intelligent integration, making it more convenient for users to use the key box for the anti-error management machine.
[0032] The housing 10 successively includes a battery area 101, an identification area 102 and a grip area 103 from top to bottom.
[0033] Among them, the battery area 101 of the outer shell 10 forms a concave groove as a battery compartment for configuring a battery (not shown in the figure). The battery is electrically connected to the control main board 20. In order to seal the battery on the outer shell 10, prevent dust and moisture from entering, and ensure the normal operation of the battery, a battery compartment cover 120 is configured on the outer shell 10 through a buckle structure, thereby maintaining the stable operation of the anti-misoperation management machine key box.
[0034] In some embodiments, the anti-misoperation management machine key box further includes a power indicator light (not shown in the figure) installed on the outer surface of the outer shell 10, and the power indicator light is electrically connected to the control main board 20.
[0035] The battery-powered method is adopted to provide power support for the entire anti-misoperation management machine key box. A battery fixing groove and electrode contacts are provided inside the battery compartment. The battery is installed in the battery fixing groove, and the electrode is in close contact with the contact to ensure stable power transmission. When the battery power is insufficient, the control main board 20 will send a prompt signal through the power indicator light. The power indicator light is electrically connected to the control main board 20 and the battery. When it is detected that the battery voltage is lower than the set threshold, the control main board 20 controls the power indicator light to flash or change color to remind the user to replace the battery in time. The user opens the battery compartment cover 120, takes out the old battery, and replaces it with a new battery.
[0036] In some embodiments, the back of the battery compartment cover 120 has a loss prevention loop 60, and a position sensor is configured inside the loss prevention loop 60 to prevent the battery compartment cover 120 from being lost.
[0037] In some embodiments, the identification area 102 of the outer shell 10 has a plurality of key holes 1021. The identification part 30 is installed on the outer shell 10. The identification part 30 includes a rubber cap board 301 and an electronic key board 302. A plurality of keyboard rubber caps 303 are installed on the rubber cap board 301, and a plurality of keyboard electronic keys 304 are installed on the electronic key board 302. The rubber cap board 301 is fixedly installed on the top of the electronic key board 302. The rubber cap board 301 is located between the electronic key board 302 and the front part of the outer shell 10 body and the three are parallel to each other. In addition to the area corresponding to the rubber cap board 301, the electronic key board 302 also has an extension part extending to directly below the grip area 103 of the outer shell 10. A through hole 3021 (for the lock core 501 to pass through to the lock tongue 502 area) is provided on the extension part of the electronic key board 302. The number of the keyboard rubber caps 303 is the same as that of the keyboard electronic keys 304 and the positions correspond one by one. The keyboard rubber caps 303 pass through the key holes 1021 of the outer shell 10 and extend to the front part of the outer shell 10, so that at least one human-computer interaction part of the identification part 30 is arranged on the front part of the outer shell 10. The user can directly operate the keyboard rubber caps 303 by hand, thereby triggering the keyboard electronic keys 304. The keyboard electronic keys 304 are electrically connected to the control main board 20.
[0038] In some embodiments, the anti-misoperation management machine key box further includes a speaker 70 installed in the housing 10, and the speaker 70 is electrically connected to the control main board 20.
[0039] When the user enters a password on the keyboard electronic key 304 through the keyboard rubber cap 303, the electrical signal generated by the key is transmitted to the control main board 20. The embedded system built into the control main board 20 compares the input password with the preset password on the management side. If the password is correct, the control main board 20 sends a signal to the driving motor 50321, and the driving motor 50321 drives the gear set 50323. The rotation of the gear set 50323 extends and retracts the lock tongue hook portion 5031, so that when the user rotates the grip 40, the lock tongue 502 can be driven to rotate, thereby smoothly opening the main box cover; if the password is incorrect, the control main board 20 will not send an unlocking instruction, and the grip 40 cannot drive the lock tongue 502 to rotate. At this time, the control main board 20 will also activate the speaker 70 to emit a warning whistle through it to remind the surrounding people to pay attention to abnormal operations. This linkage design of password verification and the lock 50 controls mechanical components with electronic signals, realizing precise control of the opening permission of the anti-misoperation management machine key box. Here, the driving motor 50321 is electrically connected to the control main board 20.
[0040] In some embodiments, the extended portion of the electronic key board 302 can be connected to the housing 10 by screws.
[0041] In some embodiments, the grip area 103 of the housing 10 has a configuration hole 1031, and the grip 40 is installed at the configuration hole 1031 of the grip 40 of the housing 10. The grip 40 includes a first grip plate portion 401 and a second protruding portion 402 protruding downward from the bottom of the first grip plate portion 401. An installation groove 4021 is provided at a corner of the second protruding portion 402. The bottom surface of the first grip plate portion 401 is in contact with the top surface of the grip area 103 of the housing 10, and the second protruding portion 402 extends from the configuration hole 1031 of the housing 10 to the inside of the housing 10.
[0042] In some embodiments, the control main board 20 is installed at the bottom of the electronic key board 302 in the identification part 30; in some embodiments, the control main board 20 uses the STM32F103 model.
[0043] As a bridge connecting the anti-misoperation management machine key box and the management terminal system, the communication interface uses a standard communication protocol (such as TCP / IP protocol) for data transmission. When the management terminal generates a password, the password data is transmitted through the network to the communication interface, which converts the data into an electrical signal suitable for processing by the control main board 20 and transmits it to the control main board 20. After being processed by the control main board 20, the password is stored in the memory and compared when the user enters the password. At the same time, the control main board 20 feeds back data such as the usage record and status information of the anti-misoperation management machine key box to the management terminal system through the communication interface. Components such as the speaker 70 and the power indicator also receive control signals sent by the control main board 20 through electrical connection with the control main board 20 to achieve corresponding functions. For example, the control main board 20 sends different audio signals to the speaker 70 according to the password comparison result to control it to emit different beeping sounds; according to the battery power detection result, it sends control signals such as on, off, and flashing to the power indicator, and each component works together to ensure the normal realization of various functions of the anti-misoperation management machine key box.
[0044] In some embodiments, the anti-misoperation management machine key box further includes: a Bluetooth module 80 communicatively connected to the control main board 20 and an electronic device (such as a mobile phone). The Bluetooth module 80 is installed inside the housing 10, and the electronic device controls the driving mechanism 5032 through information interaction with the control main board 20 via the Bluetooth module 80. The Bluetooth module 80 is the core component for realizing remote control of the lock 50 by the electronic device application. The first Bluetooth antenna contact 90 and the second Bluetooth antenna contact 100 are added inside the anti-misoperation management machine key box to increase the Bluetooth signal. The Bluetooth module 80 follows the Bluetooth communication protocol and can establish a wireless communication connection with the electronic device application. When the user opens the mobile phone application and turns on the Bluetooth function, the electronic device application searches for nearby Bluetooth devices. After identifying the Bluetooth module 80 of the anti-misoperation management machine key box, the user sends a connection request to the Bluetooth module 80 through the electronic device application. After receiving the request, the Bluetooth module 80 performs identity verification and establishes a stable Bluetooth connection after the verification passes. At this time, when the user performs an unlocking operation on the electronic device application, the electronic device application converts the unlocking instruction into a Bluetooth signal and sends it to the Bluetooth module 80. After receiving the signal, the Bluetooth module 80 transmits it to the control main board 20, and the control main board 20 controls the lock tongue rotation amplitude regulating component 503 according to the instruction to regulate the rotation amplitude of the lock tongue 502 to achieve remote unlocking. At the same time, the Bluetooth module 80 can also feedback the status information of the anti-misoperation management machine key box, such as battery power and whether it is locked, to the electronic device application, so that the user can grasp the situation of the anti-misoperation management machine key box in real time.
[0045] In some embodiments, the lock 50 includes a lock core 501, a lock tongue 502, and a lock tongue rotation amplitude regulating component 503.
[0046] The length of the lock core 501 extends along the first direction (height direction). The lock core 501 is connected to the grip 40 and forms a linkage structure. In some embodiments, the lock core 501 includes a first cylinder 5011 and a second cylinder 5012. The first cylinder 5011 is located on the top surface of the second cylinder 5012. The upper end of the first cylinder 5011 is connected in the installation groove 4021 of the second protrusion 402. The lower end of the second cylinder 5012 passes through the through hole 3021 of the electronic keypad 302 and is connected to the tongue force buffering mechanism 5022. Among them, the bottom of the second cylinder 5012 has a groove, and the bottom surface of the second cylinder 5012 is connected to the ejector spring 50222 and the lock core fixing spring 50223.
[0047] The tongue 502 includes a tongue body 5021 and a tongue force buffering mechanism 5022. The tongue body 5021 is plate-shaped and the plate length extends along the second direction (horizontal longitudinal direction). The tongue force buffering mechanism 5022 is arranged on the tongue body 5021 and is connected to the lock core 501. Among them, the second direction is perpendicular to the first direction. When the grip 40 drives the lock core 501 to rotate and the tongue 502 enters the locked state through the tongue body 5021 and the tongue force buffering mechanism 5022, during the meshing process of the tongue 502 and the lock catch, since the tongue body 5021 is stressed first and then gradually transmitted to the lock core 501 through the tongue force buffering mechanism 5022, it effectively reduces the bearing force of the lock core 501, relieves the stress concentration of the lock core 501 structure, prolongs the mechanical life of the lock core 501, and maintains the operation smoothness and structural stability during the long-term use of the lock 50.
[0048] In some embodiments, the plate body of the tongue body 5021 has a preparation groove 50211 that extends along the second direction and is configured with the tongue force buffering mechanism 5022.
[0049] In some embodiments, the lock tongue force buffer mechanism 5022 includes: a positioning pin 50221 and a spring portion, the positioning pin 50221 is located in the configuration groove of the lock tongue body 5021, the left end of the positioning pin 50221 is connected to a groove wall of the configuration groove of the lock tongue body 5021, the right end of the positioning pin 50221 has a radially extending limiting portion, the positioning pin 50221 and the spring portion are both arranged in the configuration groove of the lock tongue body 5021 and the length of both extends along the second direction, and the positioning pin 50221 and the spring portion are both connected to the bottom of the lock core 501. In some embodiments, the spring portion includes an ejector spring 50222 and a lock core fixing spring 50223. The ejector spring 50222 is sleeved on the positioning ejector 50221, and the ejector spring 50222 is stably limited on the positioning ejector 50221 due to the limiting portion. The right end of the lock core fixing spring 50223 is connected to the other groove wall of the configuration groove of the lock tongue body 5021, and the left end of the lock core fixing spring 50223 maintains a distance from the right end of the positioning ejector 50221. When the handle 40 is rotated, the power is transmitted to the lock tongue 502 through the lock core 501, causing it to move toward the lock buckle. If the anti-mistaken management machine key box is deformed due to external force at this time, causing the top of the lock tongue 502 to contact the anti-mistaken management machine key box frame in advance, the lock core fixing spring 50223 will be immediately compressed, and its length will be shortened, converting the pressure into elastic potential energy for storage; at the same time, the ejector spring 50222 will be stretched accordingly, the length will increase, and the elastic potential energy will be released to provide continuous thrust for the lock tongue 502. Under the joint action of the ejector spring 50222, the positioning ejector 50221 and the lock core fixing spring 50223, the lock tongue 502 can achieve flexible expansion and contraction and adjustment. This adaptive characteristic enables the lock tongue 502 to automatically adjust its position and length under adverse conditions such as box deformation and installation deviation, accurately adapt to the lock buckle, effectively avoid the occurrence of jamming, and ensure that the anti-mistaken management machine key box can be opened and closed normally and stably, which significantly improves the reliability and adaptability of the anti-mistaken management machine key box in complex use environments.
[0050] In some embodiments, the lock 50 further includes a lock core pressure sensor 504, a thin film pressure sensor 505 is installed on one side of the lock core pressure sensor, and the thin film pressure sensor 505 is connected to the lock tongue body 5021 through the magnet 110. The lock core pressure sensor 504 is located at the interval between the positioning ejector pin 50221 and the lock core fixing spring 50223 and contacts the two on both sides. The upper end of the lock core 501 pressure sensor is connected to the groove of the second column 5012. The lock core pressure sensor 504 is used to measure the pressure of the lock tongue force buffer mechanism 5022. Both sensors are connected to the electronic device for communication, and the measured pressure data is transmitted to the electronic device.
[0051] The tongue rotation amplitude control component 503 is used to control the rotation amplitude of the tongue 502. The tongue rotation amplitude control component 503 includes a tongue hook portion 5031 and a driving mechanism 5032 connected to the tongue hook portion 5031 and driving the tongue hook portion 5031 to move. By setting the tongue rotation amplitude control component 503, the rotation amplitude (angle) during the movement of the tongue 502 is restricted and guided, thereby affecting the opening and closing of the lock 50.
[0052] In some embodiments, the tongue hook portion 5031 includes: a first horizontal plate portion 50311, a second horizontal plate portion 50312, and a connecting portion 50313.
[0053] One side wall of the second horizontal plate portion 50312 has a tooth groove extending along the length. The length of the first horizontal plate portion 50311 is less than that of the second horizontal plate portion 50312, and the first horizontal plate portion 50311 is located directly below the second horizontal plate portion 50312. The connecting portion 50313 connects the first horizontal plate portion 50311 and the second horizontal plate portion 50312. The first horizontal plate portion 50311, the second horizontal plate portion 50312, and the connecting portion 50313 form a card slot portion adapted to the tongue body 5021, and the tongue body 5021 is located between the card slot portion and the driving mechanism 5032.
[0054] In some embodiments, the driving mechanism 5032 includes a driving motor 50321, a frame 50322, and a gear set 50323 connected to the driving motor 50321. The gear set 50323 meshes with the second horizontal plate portion 50312. The second horizontal plate portion 50312 is slidably disposed on the frame 50322, and the driving motor 50321 is mounted on the frame 50322. The card slot portion maintains linear motion through the drive of the driving mechanism 5032. The driving motor 50321 drives the gear set 50323 to drive the second horizontal plate portion 50312 to linearly slide, thereby driving the card slot portion to linearly move, and finally driving the tongue body 5021 to move by the card slot portion.
[0055] When the grip 40 is horizontally rotated to the locked state of the lock, the tongue body 5021 is locked and latched with the lock latch at the border of the key box by the rotation of the lock core 501. At this time, the tongue force buffering mechanism 5022 serves as a force transmission buffering structure for the tongue body 5021 to contact and receive force at the lock latch at the border of the anti-mismanagement key box.
[0056] The grip 40 is arranged on the front part of the anti-error management machine key box and forms a linkage structure with the lock core 501. The user can complete the insertion and extraction of the lock tongue 502 by horizontally rotating the grip 40. Compared with the traditional vertical or knob-type structure, the horizontal rotation method conforms to the ergonomic operation habit, with intuitive and simple operation and a smooth force transmission path. Especially in the anti-error management machine key box with limited space, it improves the convenience and accuracy of single-handed operation, reduces the probability of misoperation, and enhances the practical usability of the on-site anti-error system.
[0057] The foregoing is only considered to be an illustration of the principles of the present application. In addition, since many modifications and variations will be readily apparent to those skilled in the art, it is not desired to limit the present application to the exact structures and operations shown and described.
