Description

Technical Field

[0001] This utility model belongs to the field of storage cabinet technology, and in particular relates to a prefabricated storage cabinet for subway stations. Background Technology

[0002] Among the temporary storage facilities in subway stations and spare parts storage in subway warehouses, one type of locker includes a cabinet body, each with its own lock and storage space. The cabinet body is mostly made of galvanized steel plate, which is sturdy and corrosion-resistant, and the surface is treated with electrostatic powder coating, making it not easy to rust. The lockers are also equipped with capacitive touch screens, facial recognition cameras, and remote control systems. Their working principle is based on cloud technology and Internet of Things (IoT) technology. The overall system relies on smart terminals and PC servers. Through information sensing devices such as radio frequency identification (RFID), infrared sensors, global positioning systems (GPS), and laser scanners, the system connects items to the Internet according to agreed protocols to achieve intelligent identification, positioning, tracking, monitoring, and management. Users select storage or retrieval operations through the touch screen on the operation panel, and the system generates a corresponding password or barcode.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0028] This utility model provides a prefabricated storage cabinet for subway stations, see reference. Figure 1-5 As shown, it includes a central support frame 1, a storage unit 5, and a magnetic unlocking mechanism.

[0029] The central support frame 1 has multiple connection interfaces 2 on at least one side. The left and right inner walls of each connection interface 2 are symmetrically provided with limiting slots 3, and the rear end face of each connection interface 2 is provided with an electrical plug-in plate 4. The central support frame 1 has a polygonal columnar cross-section, and its inner ring is a wiring channel. The connection interfaces 2 are distributed in a matrix on each side. A base 8 is provided at the lower end of the central support frame 1, and a top plate 9 is provided at the upper end. An operation panel 10 is provided at each corner of the central support frame 1. As the core load-bearing component, the central support frame 1 provides strong support. The polygonal columnar structure and internal wiring channels ensure structural strength while achieving centralized and concealed cable management. The matrix distribution of the connection interfaces 2 and the hexagonal design of the storage units 5 allow for flexible and dense arrangement of the storage units 5 according to actual needs, resulting in high space utilization and a neat, modern appearance.

[0030] At least one storage unit 5 is provided. The storage unit 2 is in the shape of a regular hexagonal prism, and the multiple storage units 2 are arranged in a honeycomb pattern. The storage unit 2 includes a storage shell. The storage shell has a storage door at one end away from the central support frame 1. The left side of the storage door is connected to the storage shell by a hinge, and the right side of the storage door is connected to the storage shell by an electronic lock.

[0031] The storage unit 5 has a multi-functional connector 6 on its back that can be inserted into the connection interface 2. The multi-functional connector 6 includes a plug housing 61, inside which are a mechanical locking module and an electrical connection module 63. The mechanical locking module includes retractable locking components 64 symmetrically arranged on the left and right sides inside the plug housing 61 and a locking component 65 that drives the locking components 64 to extend. The locking component 65 includes a top block 654 disposed inside the plug housing 61, and the left and right sides of the top block 654 are provided with first inclined surfaces. The locking component 64 includes a retractable locking rod 643, the extended end of which cooperates with the limiting locking groove 3, and the other end of the locking rod 643 is provided with a locking push rod 645, the other end of which is provided with a second inclined surface that cooperates with the first inclined surface. When assembling the storage unit 5, pressing the storage unit 5 causes the plug housing 61 to embed into the connection interface 2. The side wall of the connection interface 2 presses against the plug housing 61, causing the two locking rods 643 to move into the plug housing 61. The inclined surface engages with the top block 654, which moves forward. When the locking rods 643 reach the position of the limiting locking groove 3, they lose the side wall pressing force. The top block 654 moves backward and, through the inclined surface engagement, extends and engages with the two locking rods 643 into the limiting locking groove 3, thus assembling the storage unit 5. Alternatively, during assembly, an external strong magnet can be inserted into the storage housing. The strong magnet attracts the magnetic block 656 on the locking slider 652, causing the top block 654 to move forward. The extension of the first return spring 644 causes the two locking rods 643 to move into the plug housing 61, facilitating the insertion of the plug housing 61 into the connection interface 2.

[0032] The snap-fit ​​assembly 64 further includes a snap-fit ​​seat 641 disposed on the inner side wall of the plug housing 61. The snap-fit ​​seat 641 is horizontally arranged along the left-right direction in its length direction. A snap-fit ​​sliding cavity is disposed inside the snap-fit ​​seat 641 along its length direction. A snap-fit ​​slider 642 is adapted to be disposed in the snap-fit ​​sliding cavity. The side of the snap-fit ​​slider 642 near the limiting snap-fit ​​groove 3 is connected to the end of the snap-fit ​​rod 643 away from the limiting snap-fit ​​groove 3. The side of the snap-fit ​​slider 642 away from the limiting snap-fit ​​groove 3 is connected to the end of the snap-fit ​​push rod 645 away from the top block 654. The portion of the snap-fit ​​rod 643 located inside the snap-fit ​​sliding cavity is also sleeved with a first return spring 644. The snap-fit ​​rod 643 and the snap-fit ​​push rod 645 are coaxially arranged, and the length directions of the snap-fit ​​rod 643 and the snap-fit ​​push rod 645 are both horizontally arranged along the left-right direction.

[0033] The end of the latching rod 643 that mates with the limiting latching groove 3 is provided with a rounded transition surface, and the rounded transition surface is located on the side of the latching rod 643 away from the storage unit 5.

[0034] The locking assembly 65 further includes a locking seat 651 located at the center of the front end inside the plug housing 61. The locking seat 651 is horizontally arranged along its length in the front-back direction. A locking slide cavity is provided inside the locking seat 651 along its length, and a locking slider 652 is adapted to fit inside the locking slide cavity. A locking rod 653 is provided on the side of the locking slider 652 away from the storage unit 5, and the other end of the locking rod 653 is connected to the top block 654. A second return spring 655 is provided on the side of the locking slider 652 near the storage unit 5. The locking rod 653 is horizontally arranged along its length in the front-back direction. The elastic force of the second return spring 655 ensures that the top block 654 always has a backward pushing force, thereby restricting the locking push rod 645, preventing the locking rod 643 from disengaging from the limiting locking groove 3, and locking the two locking assemblies 64.

[0035] Each storage unit 5 has two sets of multi-functional connectors 6 on its back. This further improves the stability of the connection between the storage unit 5 and the central support frame 1.

[0036] The electrical connection module 63 includes a plurality of first electrical contact points located at the rear end of the plug housing 61 and a second electrical contact point 41 located on the front end face of the electrical connector plate 4. The first electrical contact points are spring probes, and the second electrical contact points 41 are probe holes adapted to the spring probes. When the mechanical locking module is fully engaged, the first electrical contact points and the second electrical contact points 41 make contact and conduct. The electrical connection module 63 also includes a plurality of data connectors located at the rear end of the plug housing 61 and a data interface located on the front end face of the electrical connector plate 4. When the mechanical locking module is fully engaged, the data connectors and the data interface are connected. When the mechanical locking module is fully engaged, the rear end face of the plug housing 61 contacts the front end face of the electrical connector plate 4, the spring probes can be inserted into the probe holes on the electrical connector plate 4, and the data connectors are successfully connected to the data interface, eliminating the cumbersome separate wiring steps and improving installation efficiency and reliability.

[0037] The magnetic unlocking mechanism includes a magnetic block 656 mounted on the locking slider 652 and an external strong magnet. The magnetic block 656 is located on the end face of the locking slider 652 away from the locking rod 653. When the storage unit 5 needs to be removed for replacement or maintenance, the external strong magnet is inserted into the storage housing. The strong magnet attracts the magnetic block 656 on the locking slider 652, causing the top block 654 to move forward. The extension of the first return spring 644 causes the two locking rods 643 to move into the plug housing 61, allowing the plug housing 61 to be removed from the connection interface 2. If any single storage unit 5 malfunctions, maintenance personnel can disassemble and replace it within seconds using the above magnetic method, and then replace it with a normal unit, shortening the equipment downtime.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
