The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0028] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0029] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0030] In order to solve the problems of chaotic lock management and loss in the prior art, the present invention provides a lock management mechanism and a lock management device.

[0031] like Figures 1 to 4 A lock management mechanism shown in the figure includes a shell 10, a locking member 20 and a limit assembly 30, the shell 10 has a accommodating cavity for accommodating the lock; the locking member 20 is movably arranged in the shell 10, and switches between a locked position and an unlocked position. When the locking member 20 is in the locked position, at least a portion of the locking member 20 extends into the accommodating cavity and prevents the lock from exiting the accommodating cavity to lock the lock. When the locking member 20 is in the unlocked position, the locking member 20 exits the accommodating cavity and avoids the lock from exiting the accommodating cavity to unlock the lock; the limit assembly 30 has a movably arranged limit end 31, and the limit end 31 can extend into or exit the movement path of the locking member 20 to lock the locking member 20 in the locked position or unlock it from the locked position.

[0032] In this embodiment, a locking member 20 and a limiting assembly 30 are provided. The locking member 20 locks the lock inserted into the accommodating cavity, and the limiting assembly 30 locks the movement of the locking member 20. The two cooperate with each other to realize reliable locking of the lock. When the lock management mechanism is locked, Figure 1 As shown, the lock is inserted into the accommodating cavity, the locking member 20 moves to the locked position, and a part of the locking member 20 extends into the accommodating cavity, thereby preventing the lock from exiting the accommodating cavity, thereby achieving the effect of locking the lock in the accommodating cavity. At this time, the limiting end 31 of the limiting assembly 30 is located on the movement path of the locking member 20, thereby locking the locking member 20 in the position of extending into the accommodating cavity, and even if the lock is pulled with force, the locking member 20 cannot be squeezed out of the accommodating cavity; when it is necessary to unlock the lock management mechanism, as shown in FIG. Figure 2As shown, the limiting end 31 of the limiting assembly 30 is withdrawn from the movement path of the locking member 20, and the limiting assembly 30 no longer blocks the movement of the locking member 20, and the locking member 20 can move freely. By pulling the lock, the lock will squeeze the locking member 20 so that the locking member 20 withdraws from the accommodating cavity, and the lock is taken out for use. The above-mentioned setting method can realize intelligent centralized management of maintenance isolation locks, which is helpful for the effective management and use of maintenance locks, and ensures that the maintenance process is carried out safely and controllably.

[0033] It should be noted that the lock management mechanism of this embodiment is mainly used to control padlocks. Naturally, the lock is a padlock, and an area is formed between the lock beam and the lock body of the padlock. The locking member 20 extends into the area and contacts and squeezes the lock body of the padlock to achieve locking of the padlock. Of course, the lock management mechanism can also be used to lock and control other types of locks.

[0034] In this embodiment, the movement trajectory of the locking member 20 forms an angle with the direction in which the lock exits the accommodating cavity. Preferably, the movement trajectory of the locking member 20 and the direction in which the lock exits the accommodating cavity are perpendicular to each other, thereby ensuring that the locking member 20 can effectively stop the movement of the lock.

[0035] In this embodiment, the lock management mechanism also includes a reset member 40, which is preferably a spring. The two ends of the reset member 40 are respectively abutted against the locking member 20 and the shell 10, and provide a reset force for the locking member 20 to move to the locked position. When the limit end 31 exits the movement path of the locking member 20, due to the setting of the reset member 40, the locking member 20 will not automatically exit the accommodating cavity, and the maintenance personnel are required to pull the lock with external force. The lock will squeeze the locking member 20 to realize that the locking member 20 exits the accommodating cavity. When the lock exits the accommodating cavity or re-extends into the accommodating cavity into place, the locking member 20 will automatically extend into the accommodating cavity under the action of the reset member 40, thereby realizing automatic locking.

[0036] Optionally, one side of the accommodating cavity is an open side, and preferably only one side is open, such as Figure 3 As shown, the lock extends into or out of the accommodating cavity from the open side, and the depth of the accommodating cavity is slightly smaller than the overall length of the padlock. In this way, when the padlock is extended into the accommodating cavity, the lock body will completely penetrate into the accommodating cavity, and a part of the lock beam will be exposed, thereby facilitating the maintenance personnel to apply force when pulling out the padlock.

[0037] like Figure 1 and Figure 2As shown, the limit assembly 30 includes a solenoid 32, and the solenoid 32 includes two parts: a tube body and an inner core, wherein the tube body is fixedly connected to the housing 10, and the inner core can telescopically move under the magnetic force of the tube body, and the inner core can extend one end of the tube body as a limit end 31, and the solenoid 32 drives the inner core to move, so that the limit end 31 extends into or out of the movement path of the locking member 20, thereby locking or unlocking the locking member 20. In this embodiment, the locking member 20 is locked by the inner core abutting against the end of the locking member 20 away from the accommodating cavity. Of course, a hole groove can also be opened on the side of the locking member 20, and the locking member 20 is locked by extending the limit end 31 into the hole groove.

[0038] Optionally, the limiting assembly 30 also includes a guide member 33, which has a certain thickness along the axial direction of the inner core. The guide member 33 has a guide hole that is penetrated, and the inner core is arranged on the guide hole. The guide hole plays a certain guiding role in the movement of the inner core, so that the inner core moves along the axial direction of the guide hole under the guidance of the guide hole. At the same time, the guide member 33 is also connected to the shell 10, which can play a certain supporting role for the inner core.

[0039] like Figure 3 and Figure 4 As shown, the lock management mechanism also includes an emergency unlocking assembly 50, which includes an emergency unlocking hole 51 and an emergency unlocking pin 52. The emergency unlocking hole 51 is opened on the housing 10 and faces the limit end 31. The size of the emergency unlocking hole 51 is generally small, preferably with a diameter between 1 and 2 mm. The diameter of a part of the emergency unlocking pin 52 is slightly smaller than the diameter of the emergency unlocking hole 51 and the length is greater than the length of the emergency unlocking hole 51. When emergency unlocking is required, the emergency unlocking pin 52 is inserted into the emergency unlocking hole 51 and squeezes the limit end 31 of the limit assembly 30. The limit end 31 withdraws from the movement path of the locking member 20 under the squeezing of the emergency unlocking pin 52, thereby realizing manual unlocking of the locking member 20. By setting the emergency unlocking assembly 50, the lock management mechanism can still be emergency unlocked by manual unlocking when the electric part cannot work normally, thereby ensuring the reliable use of the lock management mechanism.

[0040] like Figure 1 and Figure 2As shown, an inclined surface is provided at one end of the locking member 20 extending into the accommodating cavity, and along the direction in which the locking member 20 extends into the accommodating cavity, the inclined surface is inclined in the direction close to the axis of the locking member 20. Since the movement of the locking member 20 to withdraw from the accommodating cavity is achieved by the extrusion of the lock, an inclined surface is provided at one end of the locking member 20 extending into the accommodating cavity. Preferably, in this embodiment, the end of the locking member 20 extending into the accommodating cavity is set to be hemispherical, and the circumferential surface of the hemispherical shape is used as the inclined surface. When the lock is pulled out of the accommodating cavity or re-extended into the accommodating cavity, the lock extrudes the hemispherical structure and also extrudes the locking member 20 so that the locking member 20 withdraws from the accommodating cavity. Once the lock body no longer extrudes the locking member 20, the locking member 20 can be re-extended into the accommodating cavity under the action of the reset member 40. Of course, the hemispherical structure can also be replaced by other shapes with inclined surfaces.

[0041] The lock management mechanism of this embodiment also includes a control circuit arranged on a circuit board, and the control circuit is electrically connected to the limit assembly 30, so as to control the action of the limit assembly 30. The lock management mechanism also includes an induction circuit for identifying the identity of the lock, and the control circuit is electrically connected to the induction circuit. The induction circuit includes an induction coil 60. When the lock is returned, the induction coil 60 matches the code chip on the lock to ensure that the lock is placed on the correct lock management mechanism. Specifically, when the induction coil 60 reads the lock code value correctly, it indicates that the lock is placed in the correct position, and the control circuit will power the solenoid 32 in the lock management mechanism, and the inner core will extend under the action of the tube body. The limit end 31 extends into the movement path of the locking member 20 to lock the locking member 20, and the locking member 20 locks the lock so that the lock cannot be taken out; when the code value read by the induction coil 60 is incorrect, the solenoid 32 in the lock management mechanism cannot be powered, the inner core will not move, and the limit end 31 will not block the movement of the locking member 20. At the same time, the indicator light on the circuit board flashes and an alarm sounds, prompting the maintenance personnel that the lock is placed in the wrong position, thereby prompting the maintenance personnel to place the lock in the specified position and not to put the lock randomly, thereby managing the lock in an orderly manner.

[0042] This embodiment also provides a lock management device, such as Figure 5As shown, the lock management device includes a cabinet 70, the lock management mechanism and the main control unit 80. There is at least one lock management mechanism and it is arranged in the cabinet 70. In this embodiment, multiple rows and columns of lock management mechanisms are arranged in one lock management device, so as to facilitate the storage and management of a large number of locks. The main control unit 80 is electrically connected to the control circuit of the lock management mechanism and controls the action of the lock management mechanism according to the authorization information. When the main control unit 80 correctly identifies the identity, the main control unit 80 controls the control circuit to power the solenoid 32 to unlock the lock, and the lock management device is unlocked, and at the same time instructs the maintenance personnel to take the corresponding lock. At this time, the lock management device also records the identity information, the time of taking, the lock number, etc. of the person who takes the lock, so as to facilitate subsequent management. The main control unit 80 includes a control host, a display screen and an authorization module, wherein the control host coordinates and controls various parts, the display screen is used to display various parameters of the lock management device, so that the maintenance personnel can judge the status of the lock management device, and the authorization module includes a password input unit, a card recognition unit and / or a biometric recognition unit, which is used to identify and verify the identity of the maintenance personnel. When a biometric identification unit is provided, the biometric identification unit includes a collection terminal for fingerprint recognition, iris recognition and / or face recognition, which is used to collect information of maintenance personnel for data matching and thus verify identity.
