[0001] The invention relates to the technical field of key cabinets, and in particular to a direct-insert-and-drop key storage cabinet and an access control method thereof. Background Art

[0002] In various places in modern society, the safe storage and efficient management of keys has always been an important issue. Existing ordinary key cabinets usually use simple mechanical lock structures, which can only provide the most basic locking function. In addition, when storing keys, you need to open the hinged lock cover first, and then put the key into the cabinet cavity. When taking out the key, you also need to open the hinged lock cover and then take the key out of the key cabinet cavity. The operation process is not only cumbersome, but also the hinged lock cover takes up more space when opened outward, and the small cabinet cavity is small in size, which will affect the human posture of key storage and retrieval.

[0003] In summary, how to further simplify the key storage and access operations and reduce the impact of the key storage cabinet on human posture when accessing keys has become a problem that needs to be solved. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a direct insertion and drop-in key storage cabinet and an access control method thereof, thereby further simplifying the key access operation and reducing the influence of the key storage cabinet on human posture when accessing the key.

[0005] The present invention is achieved through the following technical solutions:

[0006] A straight-insert drop-in key storage cabinet comprises a cabinet body, wherein a plurality of parallel storage rings are built in the cabinet body, a group of ring side baffles are arranged on the outer periphery of the storage ring side, and a plurality of groups of first guide cylinders and second guide cylinders are arranged on the bottom side of the cabinet body, a group of first guide cylinders and second guide cylinders are independently arranged under each storage ring, and a driving rod for driving the storage ring to rotate is driven and connected between the first guide cylinders and the second guide cylinders in the same group.

[0007] The storage ring includes an outer ring, an inner plug-in box installed on the inner periphery of the outer ring, and an end cover installed on the side end of the outer ring. A bearing ring is arranged between the end covers of adjacent storage rings. A storage and access wide opening is provided on the top of the outer ring, a toothed section is provided on the outer ring, and an insertion slot aligned with the storage and access wide opening is provided on the inner plug-in box. A first detection hole is provided through the outer ring, and a second detection hole is provided in the inner plug-in box, which is vertically connected to the insertion slot. The first detection hole and the second detection hole are aligned. A group of ring side baffles form an upper opening located above the storage and access wide opening at the upper end, and a photoelectric detection module whose detection direction is aligned with the first detection hole and the second detection hole is embedded in one of the ring side baffles. The driving rod includes a rod body, a permanent magnet located at one end of the rod body, and a guide located at the other end of the rod body. A toothed section meshing with the toothed section is provided on the ring side of the rod body. An electromagnetic mechanism magnetically matched with the permanent magnet is provided in the first guide cylinder, and a spring connected with the guide is provided in the second guide cylinder.

[0008] The cabinet is also equipped with a main controller and multiple electric switches. The main controller is equipped with a touch screen with fingerprint recognition. Each electric switch is independently electrically connected to an electromagnetic mechanism. The electric switch is also equipped with an indicator light.

[0009] As a preferred technical solution for the key storage cabinet of the present invention: the outer ring member is provided with a group of longitudinal mounting holes, the inner plug-in box is provided with a group of vertical screw holes aligned with the longitudinal mounting holes, and bolt members are fixed at the positions of the longitudinal mounting holes and the vertical screw holes.

[0010] As a preferred technical solution for the key storage cabinet of the present invention: the end cover is provided with a plurality of axial mounting holes, the side end of the outer ring is provided with a plurality of axial screw holes aligned with the axial mounting holes, and bolts are fixed at the positions of the axial mounting holes and the axial screw holes.

[0011] As a preferred technical solution of the key storage cabinet of the present invention: the inner wall of the insertion slot of the inner insertion box is provided with a group of limiting spring pieces for clamping the key.

[0012] As a preferred technical solution of the key storage cabinet of the present invention: the width dimension of the upper opening is larger than the opening dimension of the access opening.

[0013] As a preferred technical solution of the key storage cabinet of the present invention: when the electromagnetic mechanism is powered off and demagnetized, the access opening of the outer ring member is directly opposite to the upper opening.

[0014] As a preferred technical solution of the key storage cabinet of the present invention: the horizontal height of the second detection hole is higher than the horizontal height of the bottom surface of the insertion slot.

[0015] A method for controlling access to a direct insertion key storage cabinet includes the following contents:

[0016] S1. When storing the key, click the touch screen and press the fingerprint of your finger directly on the fingerprint area. After the touch screen prompts success, the indicator light corresponding to the position where the key is not inserted begins to flash, and the photoelectric detection module at this position is started.

[0017] S2. Insert the key directly into the storage ring with the flashing indicator light, and insert the key down along the access opening and insertion slot to the bottom.

[0018] S3. The photoelectric detection module detects the photoelectric blocking signal toward the first detection hole and the second detection hole. When a blocking signal is detected in the insertion slot, the electromagnetic mechanism electromagnetically attracts the permanent magnet and locks it. The tooth section of the rod body drives the tooth section of the outer ring to move, and the outer ring rotates. The access opening of the outer ring is separated from the upper opening and hidden inside the cabinet.

[0019] S4. When taking out the key, click the touch screen and press the fingerprint of your finger directly on the fingerprint area. After the touch screen prompts success, the indicator light corresponding to the position where the key is not inserted begins to flash, and the photoelectric detection module at this position is started. At the same time, the electromagnetic mechanism is powered off and demagnetized, and the spring part drives the rod body to move. The tooth section of the rod body drives the tooth section of the outer ring part to move, and the outer ring part rotates in the opposite direction, and the access opening of the outer ring part is reset to align with the upper opening.

[0020] S5. Pull out the key from the access port, the photoelectric detection module detects that the blocking signal disappears, the indicator light stops flashing, and the main controller's built-in program marks the current storage location as an empty area where no key is inserted. That is, when there is a need to store new keys in the future, the empty area can be used as a key storage area.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The storage ring of the present invention is equipped with an outer ring member and an inner plug-in box. A wide storage and access opening is provided on the outer ring member, and an insertion slot is provided on the inner plug-in box. The wide storage and access opening can be hidden inside the cabinet under the action of an electromagnetic mechanism and a driving rod member, without occupying additional space, making the overall structure of the key cabinet more compact, improving the human operating space when storing and retrieving keys, and accurately detecting whether the key is inserted and the position status of the storage ring through a photoelectric detection module, ensuring that the storage process is accurate and making key storage more convenient.

[0023] 2. The present invention uses touch screen and fingerprint recognition technology. The user only needs to click the touch screen and press the fingerprint. The indicator light corresponding to the position where the key is not inserted will flash to prompt that the key can be stored or taken out. There is no need for complicated lock cover opening operation, which simplifies the key storage and access operation and improves the operating efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0033] Embodiment 1. The present invention designs a direct insertion and drop-in key storage cabinet, which mainly includes a storage ring 2, a ring side baffle 3, a photoelectric detection module 4, a first guide cylinder 5, a second guide cylinder 6, a driving rod 7, an electromagnetic mechanism 8, a spring member 9, an electric control switch 10, a main controller 12 and other components. The specific structural configuration is as follows:

[0034] ㈠Cabinet 1:

[0035] like Figure 1 , Figure 3 , Figure 6, serving as the outer shell of the entire key storage cabinet, is used to accommodate and protect the various internal components. It is made of sturdy materials, has a certain strength and stability, and can prevent external impact and damage. The interior of the cabinet 1 is designed to accommodate multiple parallel storage rings 2, and its spatial layout is reasonable to ensure that the storage rings 2 can be installed and rotated smoothly. On the bottom side of the cabinet 1, multiple groups of first guide cylinders 5 and second guide cylinders 6 are configured. The positions of these guide cylinders correspond one-to-one to the storage rings 2, providing a guiding function for the installation and movement of the drive rod 7, ensuring that the rotation process of the storage ring 2 is stable and accurate.

[0036] (ii) Storage Ring 2:

[0037] like Figure 1 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Outer ring 201: A wide access opening 2012 is provided at the top to facilitate the insertion and removal of the key. The outer ring 201 is provided with a toothed portion 2013, which is used to mesh with the toothed portion 702 of the driving rod 7 to achieve power transmission, thereby driving the storage ring 2 to rotate. The outer ring 201 is provided with a first detection hole 2011, which is aligned with the second detection hole 2023 of the inner plug-in box 202 to provide a channel for the photoelectric detection module 4 to detect whether the key is inserted. In addition, the outer ring 201 is provided with a group of longitudinal mounting holes 2014, which are aligned with the vertical screw holes 2022 of the inner plug-in box 202 and fixed with bolts to ensure the stability of the installation of the inner plug-in box 202. At the same time, a plurality of axial screw holes 2015 are provided on the side end of the outer ring 201, which are matched with the axial mounting holes 2031 of the end cover 203 to install bolts, so that the end cover 203 is tightly connected to the outer ring 201.

[0038] like Figure 2 , Figure 6 , Figure 7 , Insert box 202: Installed inside the outer ring 201, with an insertion slot 2021 that is aligned with the access opening 2012, the key is inserted into the storage ring 2 along the access opening 2012 and the insertion slot 2021. The inner wall of the insertion slot 2021 of the insert box 202 is configured with a group of limit springs 2024 for clamping the key. When the key falls into the insertion slot 2021, the limit springs 2024 form an elastic limit for the key, making the position of the key more stable, and preventing the key from shaking or falling during the rotation of the storage ring 2. The insert box 202 is provided with a group of vertical screw holes 2022 that are aligned with the longitudinal mounting holes 2014 of the outer ring 201, and a second detection hole 2023 that is vertically connected to the insertion slot 2021 and has a horizontal height higher than the bottom surface of the insertion slot 2021.

[0039] like Figure 4 , Figure 5 , Figure 6 , End cover 203: Installed on the side of the outer ring 201, with multiple axial mounting holes 2031, and equipped with bolts in cooperation with the axial screw holes 2015 on the side of the outer ring 201 to ensure the tightness of the connection between the end cover 203 and the outer ring 201. A bearing ring 204 is arranged between the end covers 203 of adjacent storage rings 2. The bearing ring 204 not only connects and supports the adjacent storage rings 2, but also reduces the friction between the storage rings 2, making the rotation of the storage rings 2 smoother.

[0040] (iii) Ring side baffle 3:

[0041] like Figure 1 , Figure 6 , which is arranged on the outer side of the storage ring 2 to protect and isolate the storage ring 2. A set of ring side baffles 3 have an upper opening 301 formed on the upper end thereof, which is located above the access opening 2012. The width of the upper opening 301 is larger than the opening size of the access opening 2012, which is convenient for key insertion. One of the ring side baffles 3 is embedded with a photoelectric detection module 4 whose detection direction is aligned with the first detection hole 2011 and the second detection hole 2023. The photoelectric detection module 4 can detect the photoelectric blocking signal through the first detection hole 2011 and the second detection hole 2023, thereby determining whether a key is inserted into the insertion slot 2021, and providing a basis for the subsequent rotation control of the storage ring 2.

[0042] (iv) Driving rod 7:

[0043] like Figure 1 , Figure 3 , Figure 6 , rod body 701: a tooth section 702 meshing with the tooth portion 2013 is provided on its ring side. When the rod body 701 is moved by an external force, the tooth section 702 can drive the tooth portion 2013 of the outer ring 201 to move, thereby realizing the rotation of the storage ring 2.

[0044] like Figure 1 , Figure 3 , Figure 4 , Figure 6 , Permanent magnet 703: located at one side end of the rod body 701, and magnetically cooperates with the electromagnetic mechanism 8 in the first guide cylinder 5. When the electromagnetic mechanism 8 is powered on, a magnetic field is generated to attract the permanent magnet 703, so that the driving rod 7 is kept in a specific position, thereby locking the position of the storage ring 2. When the electromagnetic mechanism 8 is powered off and loses magnetism, the permanent magnet 703 and the electromagnetic mechanism 8 are separated from the magnetic attraction.

[0045] like Figure 1 , Figure 3 , Figure 6, Guide member 704: located at the other end of the rod body 701, connected to the spring member 9 in the second guide cylinder 6. The spring member 9 provides elastic force for the driving rod member 7 to reset. When the electromagnetic mechanism 8 is powered off and demagnetized, the spring member 9 drives the rod body 701 to move, so that the storage ring 2 rotates in the opposite direction to reset.

[0046] ㈤Electromagnetic mechanism 8:

[0047] like Figure 1 , Figure 3 , Figure 4 , Figure 6 , installed in the first guide cylinder 5, and magnetically cooperates with the permanent magnet 703. When storing the key, when the photoelectric detection module 4 detects that a key is inserted into the insertion slot 2021, the electromagnetic mechanism 8 electromagnetically attracts the permanent magnet 703 and locks it, so that the storage ring 2 remains in the position where the key has been stored; when taking out the key, the electromagnetic mechanism 8 is powered off and demagnetized, and the permanent magnet 703 is released, so that the storage ring 2 can be reset under the action of the spring member 9.

[0048] (vi) Spring member 9:

[0049] like Figure 1 , Figure 3 , Figure 6 , disposed in the second guide cylinder 6, and connected to the guide member 704 of the driving rod 7. When the electromagnetic mechanism 8 is powered off and loses its magnetism, the spring member 9 uses its own elastic force to drive the rod body 701 to move, so that the storage ring 2 rotates in the opposite direction, so that the access opening 2012 is reset to align with the upper opening 301, making it convenient to take out the key.

[0050] ㈦Electric switch 10:

[0051] like Figure 1 , Figure 3 , Figure 6 Each electric control switch 10 is independently electrically connected to an electromagnetic mechanism 8 to control the power-on and power-off states of the electromagnetic mechanism 8. Through the operation instructions of the touch screen 13, the electric control switch 10 can accurately control the operation of the corresponding electromagnetic mechanism 8 to achieve precise control of the rotation of the storage ring 2.

[0052] In addition, the indicator light 11 is provided in conjunction with the electric control switch 10 to indicate the position where the user can store or take out the key. When the touch screen 13 is clicked and the fingerprint is recognized, the indicator light 11 corresponding to the position where the key is not inserted begins to flash, guiding the user to insert the key into the correct storage ring 2 position.

[0053] (VIII) Main controller 12:

[0054] like Figure 1 , Figure 4 , Figure 6, as the control core of the entire key storage cabinet, is responsible for coordinating the work of various components. The main controller 12 is equipped with a touch screen 13 with fingerprint recognition. The user inputs operation instructions through the touch screen 13, such as fingerprint recognition verification, storage ring 2 position selection and other operations. The main controller 12 controls the on and off of the electric control switch 10 according to the instructions of the touch screen 13 and the detection signal of the photoelectric detection module 4, thereby realizing precise control of the rotation of the storage ring 2 and the key access process. At the same time, the built-in program of the main controller 12 can mark the current storage position as an unloaded area where no key is inserted, so as to facilitate subsequent management and use.

[0055] In addition, the main controller 12 is also equipped with a touch screen 13 with a fingerprint recognition function. When the user stores or takes out the key, he first clicks the touch screen 13, and then presses the fingerprint of the finger in the fingerprint area for identity verification. After successful verification, the touch screen 13 will prompt the user to operate, and control the corresponding indicator light 11 to flash, guiding the user to complete the key storage and access operation. At the same time, the touch screen 13 can also display the working status of the key storage cabinet, the use of the storage ring 2 and other information, which is convenient for users to understand and manage.

[0056] Embodiment 2: The present invention designs an access control method for a direct insertion key storage cabinet, and the specific principle is as follows:

[0057] Operation 1: When storing the key:

[0058] First, click the touch screen 13 and directly press the fingerprint of the finger in the fingerprint area, and the touch screen 13 will identify and verify the fingerprint. If the verification is successful, the indicator light 11 corresponding to the position where the key is not inserted begins to flash, and the photoelectric detection module 4 at this position is started to prepare to detect the key insertion.

[0059] Then, the user directly inserts the key into the storage ring 2 with the indicator light 11 flashing, and inserts it downward along the access opening 2012 and the insertion slot 2021 to the bottom, ensuring that the key is completely inserted into the inner box 202.

[0060] The photoelectric detection module 4 detects the photoelectric blocking signal toward the first detection hole 2011 and the second detection hole 2023. When the blocking signal is detected in the insertion slot 2021, it indicates that the key has been successfully inserted. At this time, the electromagnetic mechanism 8 electromagnetically attracts the permanent magnet 703 and locks it. The toothed section 702 of the rod body 701 of the driving rod 7 drives the toothed section 2013 of the outer ring 201 to move, so that the outer ring 201 rotates, and the access opening 2012 of the outer ring 201 is separated from the upper opening 301 and hidden inside the cabinet 1, completing the key storage operation.

[0061] Operation 2: When taking out the key:

[0062] First, click the touch screen 13 and press the fingerprint of the finger directly in the fingerprint area. After the touch screen 13 successfully verifies the fingerprint, the indicator light 11 corresponding to the position where the key is not inserted begins to flash, the photoelectric detection module 4 at this position is started, and the electromagnetic mechanism 8 is powered off and demagnetized.

[0063] The spring member 9 drives the rod body 701 of the driving rod member 7 to move, and the toothed section 702 of the rod body 701 drives the toothed portion 2013 of the outer ring member 201 to move, and the outer ring member 201 rotates in the opposite direction, and the access opening 2012 of the outer ring member 201 is reset to align with the upper opening 301.

[0064] Then, the user pulls out the key from the access opening 2012, the photoelectric detection module 4 detects that the blocking signal disappears, the indicator light 11 stops flashing, and the main controller 12 has a built-in program to mark the current storage position as an empty area where no key is inserted, so as to facilitate the identification of available positions when storing the key later.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
