[0043] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. The following embodiments and features in the embodiments can be combined with each other without conflict. On the basis of the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0044] See also Figure 1 and Figure 2 An embodiment of the present application provides a cabinet lock, which includes a shell 10, a rotating member 11, a clutch member 12 and a first driving member 13. A cavity is provided in the shell 10, and the rotating member 11, the clutch member 12 and the first driving member 13 are all provided in the cavity.

[0045] In a specific implementation, the material of the housing 10 may be plastic or metal, and the shape of the housing 10 includes but is not limited to a rectangle or a square. Figure 1 As shown, in an optional embodiment of the present application, the edge portions around the shell 10 may have a certain slope 102. By setting the slope 102, there is no fulcrum when prying or destroying, thereby increasing the difficulty of destroying the cabinet lock and making it difficult to be destroyed.

[0046] See also Figure 2 The housing 10 is provided with a first opening 101, and the rotating member 11 is arranged corresponding to the first opening 101. Specifically, a groove adapted to the rotating member 11 may be provided in the housing 10, so that the rotating member 11 is placed in the groove.

[0047] See also Figure 2 and Figure 3 The rotating member 11 is provided with a clutch opening 111 , and the clutch member 12 is connected to the first driving member 13 . The first driving member 13 can drive the clutch member 12 to be embedded in or out of the clutch opening 111 .

[0048] The first driving member 13 may be a motor driving system. The first driving member 13 communicates with the control system in a wireless or wired manner. The control system sends an unlocking instruction or a locking instruction to the first driving member 13 according to actual needs. Fig. 9 , the control system includes a remote control system and a Bluetooth communication module, the remote control system and the Bluetooth communication module are connected, and the remote control system can send an unlocking instruction or a locking instruction to the first drive member 13 by controlling the Bluetooth communication module. When the remote control system fails, the Bluetooth communication module can also receive instructions sent by the mobile phone user through the mobile phone software network to send an unlocking instruction or a locking instruction to the first drive member 13. That is to say, the Bluetooth communication module can parse the encrypted authority to the first drive member 13 to drive the clutch member 12 to unlock, and can also control the first drive member 13 to unlock through the instructions issued by the remote control system. In this example, compared with the control system in the prior art, it is possible to implement functions such as authority issuance and deletion on the mobile phone Bluetooth platform, and not only rely on the remote control system to control the first drive member 13.

[0049] Furthermore, the control system has the function of automatically retaining the unlocking record of the mobile phone Bluetooth platform, which can promptly detect abnormal unlocking of the mobile phone Bluetooth platform and revoke the authority.

[0050] When receiving the unlocking instruction, the first driving member 13 drives the clutch member 12 to disengage from the clutch opening 111 , so that the rotating member 11 is in a rotatable state. At this time, the rotating member 11 can be rotated through the first opening 101 to unlock the cabinet.

[0051] When the first driving member 13 receives the locking instruction, it drives the clutch member 12 to engage in the clutch opening 111, so that the rotating member 11 is in a non-rotatable state. At this time, the rotating member 11 cannot be rotated through the first opening 101, and the cabinet lock cannot be opened.

[0052] The rotating member 11, the clutch member 12 and the first driving member 13 are equivalent to a mechanical lock core and are all placed in the cavity. The housing 10 protects the rotating member 11, the clutch member 12 and the first driving member 13, making them difficult to be damaged.

[0053] In addition, the first driving member 13 is controlled by the control system. When the first driving member 13 receives a lock command, it drives the clutch member 12 to embed into the clutch opening 111, and the entire shell 10 is only provided with the first opening 101. At this time, it is difficult to open the cabinet lock technically.

[0054] In summary, in the embodiment of the present application, the cabinet lock includes a shell, a rotating member, a clutch member and a first driving member, and a cavity is provided in the shell, and the rotating member, the clutch member and the first driving member are all arranged in the cavity. The shell is provided with a first opening, and the rotating member is arranged corresponding to the first opening; the rotating member is provided with a clutch port, and the clutch member is connected to the first driving member, and the first driving member can drive the clutch member to be embedded in or out of the clutch port. Wherein, when the first driving member receives an unlocking instruction, it drives the clutch member to be out of the clutch port so that the rotating member is in a rotatable state; when the first driving member receives a locking instruction, it drives the clutch member to be embedded in the clutch port so that the rotating member is in a non-rotatable state. In this way, the rotating member, the clutch member and the first driving member equivalent to the mechanical lock core can be placed in the cavity, and the shell protects the rotating member, the clutch member and the first driving member, making them difficult to be damaged, thereby improving the safety of the cabinet lock.

[0055] In addition, since the first driving member 13 is controlled by the control system, when the first driving member 13 receives the locking command, the clutch member 12 is driven to embed into the clutch opening 111, and the entire shell 10 is only provided with the first opening 101. At this time, it is difficult to open the cabinet lock technically, thereby further improving the safety of the cabinet lock.

[0056] In order to further improve the safety of the cabinet lock and prevent violent unlocking, in an optional embodiment of the present application, see Figure 2 The cabinet lock further includes a vibration sensor 14, which is located in the cavity and is arranged corresponding to the first opening 101. The vibration sensor 14 is connected to the control system in a communication manner. Specifically, the vibration sensor 14 can be connected to the control system in a wired or wireless manner.

[0057] When the cabinet lock is pried or maliciously damaged, the vibration sensor 14 senses the vibration and can promptly send an alarm message to the control system, so that the management personnel can promptly intervene in the malicious damage to the cabinet lock / forced unlocking behavior, thereby effectively stopping the malicious damage to the cabinet lock / forced unlocking behavior.

[0058] The vibration sensor 14 may also be replaced with an infrared sensor or other applicable condition alarms.

[0059] In actual applications, there is a situation where the first drive member 13 fails and cannot be controlled by the control system or loses power (the first drive member 13 loses power), resulting in the first drive member 13 being unable to drive the clutch member 12 to engage in or disengage from the clutch port 111. In this case, whether the cabinet lock can be unlocked is completely out of control. If the cabinet lock needs to be opened or the cabinet lock is in a state where it cannot be opened, it cannot be achieved. The reliability of the cabinet lock is poor.

[0060] To solve the problem of poor reliability of cabinet locks, optionally, see Figure 2 and Figure 4 The cabinet lock further includes a second driving member 15 and a pull plate 16, and the housing 10 is further provided with a second opening 102. The first end of the second driving member 15 is arranged corresponding to the second opening 102, the second end of the second driving member 15 is fixedly connected to the first end of the pull plate 16, and the second end of the pull plate 16 is connected to the clutch member 12.

[0061] The second driving member 15 can be rotated through the second opening 102, and the second driving member 15 can drive the pull plate 16 to move, so as to pull the clutch member 12 to fit into or out of the clutch opening 111. The clutch member 12 is out of the clutch opening 111, so that the rotating member 11 is in a rotatable state, and at this time, the rotating member 11 can be rotated through the first opening 101 to open the cabinet lock; the clutch member 12 is inserted into the clutch opening 111, so that the rotating member 11 is in a non-rotatable state, and at this time, the rotating member 11 cannot be rotated through the first opening 101, and the cabinet lock cannot be opened.

[0062] The second driving member 15 is a mechanical control member, which does not require electrical energy and can be manually rotated through the second opening 102. In this way, even if the first driving member 13 fails or loses power, the cabinet lock can be opened through the second driving member 15 and the pull plate 16, or the cabinet lock can be placed in a state where it cannot be opened, thereby improving the reliability of the cabinet lock.

[0063] In an optional embodiment of the present application, see Figure 2 and Figure 5 The second driving member 15 can be a mechanical lock core system, which is fixedly connected to the pull groove 161 of the pull plate 16, and the pull hook 163 of the pull plate 16 is fixedly connected to the linkage latch 121 of the clutch member 12. Figure 2 and Figure 5 The pull plate 16 is provided with a positioning groove 162 , and the positioning column 17 passes through the positioning groove 162 and is slidably connected to the positioning groove 162 . When the pull plate 16 moves, the pull plate 16 moves along the trajectory restricted by the positioning groove 162 .

[0064] Alternatively, see Figure 1 The cabinet lock further includes a waterproof plate 103 located outside the housing 10, and the waterproof plate 103 is rotatably disposed at the second opening 102. In a specific implementation, the waterproof plate 103 is fixed to the housing 10 by bolts 104. The provision of the waterproof plate 103 can prevent water from entering the cabinet lock, causing the internal components of the cabinet lock to be rusted.

[0065] In order to further improve the safety of the cabinet lock and prevent the vandal from maliciously unlocking the cabinet lock through the second drive member 15, optionally, see Figure 2 and Figure 5 The cabinet lock also includes a limiting piece 18, a locking piece 19 and an electromagnetic locking device 20.

[0066] The limiting plate 18 is provided with a connecting hole 181 and a limiting bayonet 182. The second end of the second driving member 15 includes a connecting column, which passes through the connecting hole 181 and is fixedly connected to the connecting hole 181 and the first end of the pull plate 16 respectively.

[0067] The locking piece 19 is matched with the limiting bayonet 182 , and the locking piece 19 is arranged corresponding to the electromagnetic locking device 20 . Under the control of the electromagnetic locking device 20 , the locking piece 19 can be embedded in or separated from the limiting bayonet 182 .

[0068] Specifically, the electromagnetic locking device 20 is controlled by the control system. When the control system allows the cabinet lock to be in an unlockable state through the second driving member 15, the movable bolt 201 of the electromagnetic locking device 20 does not contact the locking plate 19, and the locking plate 19 is separated from the limiting bayonet 182. At this time, the second driving member 15 can be rotated to make the clutch member 12 separate from the clutch port 111, and the rotating member 11 is in a rotatable state. The cabinet lock can be opened by rotating the rotating member 11 through the first opening 101. When the locking plate 19 is separated from the limiting bayonet 182, the limiting plate 18 moves with the second driving member 15.

[0069] When the control system does not allow the cabinet lock to be in an unlockable state through the second driving member 15, the movable bolt 201 of the electromagnetic locking device 20 pushes the locking plate 19, so that the locking plate 19 is embedded in the limiting bayonet 182, and the movable bolt 201 abuts against the locking plate 19, and the movable bolt 201 is affected by the magnetic field in the electromagnetic locking device 20 and cannot move in a direction away from the locking plate 19. At this time, the limiting plate 18 restricts the rotation of the second driving member 15, and the clutch member 12 cannot be controlled to disengage from the clutch port 111 by rotating the second driving member 15. The rotating member 11 is in a non-rotatable state, and the rotating member 11 cannot be rotated through the first opening 101 to open the cabinet lock.

[0070] In the embodiment of the present application, by providing the limiting piece 18, the locking piece 19 and the electromagnetic locking device 20, the second driving member 15 can be controlled to prevent a vandal from maliciously unlocking the cabinet lock through the second driving member 15, thereby improving the security of the cabinet lock.

[0071] Alternatively, see Figure 2 , the pad column 191 can be fixedly connected to the locking piece 19, so that the locking piece 19 and the limiting piece 18 are just at the same level, so that the locking piece 19 can be just embedded in the limiting bayonet 182. Specifically, the pad column 191 can be fixedly connected to the pad column 191 through the mounting hole 271 provided on the bracket piece 27.

[0072] It should be noted that the second driving member 15 and the electromagnetic locking device 20 can be powered by the same power supply. When the power is lost (the electromagnetic locking device 20 loses power), the movable bolt 201 of the electromagnetic locking device 20 does not contact the locking plate 19, and the locking plate 19 is disengaged from the limit stop 182. At this time, rotating the second driving member 15 can cause the clutch member 12 to disengage from the clutch port 111.

[0073] Further, see Fig. 9 The control system includes a remote control system and a Bluetooth communication module. The remote control system and the Bluetooth communication module are connected. The remote control system can control the Bluetooth communication module to send an unlocking instruction or a locking instruction to the first drive member 13. The first drive member 13 and the electromagnetic locking device 20 are controlled simultaneously. The Bluetooth communication module can be connected to an external power supply to keep it powered on. The Bluetooth communication module achieves unlocking by receiving instructions sent by a mobile phone user. By setting up a Bluetooth communication module, unlocking can be achieved through instructions sent by a mobile phone user when the remote control system fails. The Bluetooth communication module can upload the unlocking record in real time to the intelligent background used to control the Bluetooth communication module, and the intelligent background can also report the unlocking record to the remote control system. In this example, it has the following beneficial effects:

[0074] By controlling the first driving member 13 and the electromagnetic locking device 20 simultaneously, the safety of the cabinet lock can be further improved.

[0075] The external power supply of the Bluetooth communication module can keep it powered on, and the cabinet lock will not be unable to be unlocked or locked due to power outage.

[0076] By setting up a Bluetooth communication module, when a remote control system fails, the lock can be unlocked through the intelligent background authorization used to manage the Bluetooth communication module. The unlocking record can also be uploaded in real time, which improves the intelligence of the cabinet lock.

[0077] Furthermore, if both the remote control system and the Bluetooth communication module lose power or fail, the lock can be unlocked by the second drive member 15, and regardless of whether there is an unlocking command or a locking command, the lock can be unlocked by the second drive member 15 when necessary, thereby improving the reliability of the cabinet lock.

[0078] Alternatively, see Figure 2 The cabinet lock further includes a first magnetic sensor 21 and an alarm 22, and the clutch 12 is provided with a first magnet 122. Specifically, a magnet hole 123 can be opened on the clutch 12, and the first magnet 122 is arranged in the magnet hole 123.

[0079] The first magnetic sensor 21 is connected to the alarm 22. Specifically, the first magnetic sensor 21 can be connected to the alarm 22 in a wired or wireless manner.

[0080] In the case where the clutch 12 is separated from the clutch port 111, the first magnetic sensor 21 can detect the magnetic field signal of the first magnet 122. When the first magnetic sensor 21 detects the magnetic field signal, it sends the first information to the alarm 22 to instruct the alarm 22 to alarm. In this way, when the clutch 12 is separated from the clutch port 111, the alarm 22 can be used to inform the administrator of the cabinet lock that the cabinet lock is in a state where it can be unlocked. If the state is not allowed, the administrator can stop the sending of the state in time, thereby improving the safety of the cabinet lock.

[0081] Alternatively, see Figure 3 The cabinet lock further includes a second magnetic sensor 23, the clutch member 12 is provided with a second magnet, and the second magnetic sensor 23 is connected to the control system for communication. Specifically, the second magnet and the first magnet 122 can be the same magnet or two different magnets.

[0082] When the clutch 12 is embedded in the clutch opening 111, the second magnetic sensor 23 can detect the magnetic field signal of the second magnet. When the second magnetic sensor 23 detects the magnetic field signal, it sends second information to the control system to indicate that the cabinet lock is in a locked state.

[0083] By providing the second magnet and the second magnetic sensor 23, the control system can obtain the state of the cabinet lock, so as to intervene in time when the cabinet lock is in an abnormal state, thereby improving the safety of the cabinet lock.

[0084] Alternatively, see Figure 2 , Figure 3 and Figure 6 The cabinet lock further includes an unlocking shaft 24 located in the cavity, and the rotating member 11 is provided with a rotating opening 112. The first end of the unlocking shaft 24 is fixedly connected to the rotating opening 112, and the second end of the unlocking shaft 24 is located at the first opening 101, and the second end of the unlocking shaft 24 is adapted to the first opening 101.

[0085] In a specific implementation, the first end of the unlocking shaft 24 is provided with a collar groove 242, the collar 241 is embedded in the collar groove 242, and the first end of the unlocking shaft 24 is fixedly connected to the rotating opening 112 through the collar 241 and the collar groove 242. The unlocking shaft 24 can be rotated to drive the rotating member 11 to rotate, so as to open the cabinet lock.

[0086] In order to change the cross-sectional shape of the main lock or the bolt or the knob lock, and improve its structural rigidity without affecting the fluidity of the structure, thereby improving the explosion-proof performance, optionally, see Figure 1 The first opening 101 is in a triangular shape. Accordingly, the longitudinal section of the second end of the unlocking shaft 24 is in a triangular shape, and the longitudinal section of the first end of the unlocking shaft 24 is in a rectangular shape or other suitable shapes.

[0087] Alternatively, see Figure 2 and Figure 3 The cabinet lock further includes a limit pin 25 located in the cavity, the rotating member 11 is provided with a limit opening 113, and the limit pin 25 is slidably connected with the limit opening 113;

[0088] When the rotating member 11 rotates, the rotating member 11 moves along a trajectory limited by the limiting pin 25 .

[0089] In a specific implementation, one end of the limit pin 25 passes through the through hole of the cover plate 26 and is fixedly connected thereto, and the other end of the limit pin 25 is fixedly connected to the through hole on the housing 10. The limit opening 113 may be an arc-shaped opening. When the rotating member 11 rotates, the limit pin 25 is located at the leftmost end or the rightmost end of the limit opening 113, corresponding to the state of opening or closing the cabinet lock, respectively.

[0090] See also Figure 2 A bracket sheet 27 may be provided to fix the second driving member 15 to the housing 10 , and a shield 28 may be provided to protect the internal components of the housing 10 .

[0091] See also Figure 7 At least one of the following structures may be provided in the housing 10 to install and fix the internal components of the housing 10:

[0092] A first mounting groove 29 for mounting the rotating member 11;

[0103] It should be noted that mounting holes, mounting grooves, etc. may be provided according to actual needs to fix and install the components in the housing 10 .

[0104] The positional relationship between the components in the housing 10 (such as the pull plate 16, the cover plate 26, the unlocking shaft 24 and the electromagnetic locking device 20) is as follows: Figure 8 The components inside the housing 10 can be fixed by bolting, welding, or bonding.

[0105] It should be noted that the cabinet lock provided in the embodiment of the present application can use a built-in battery and be equipped with a number of No. 5 batteries. The battery supplies power to the components inside the cabinet lock that require electrical energy, namely the first drive member 13 and the electromagnetic locking device 20.
