Technical Field
[0001] This invention relates to the technical field of cabinets, shelves, or racks specifically for storing books, documents, forms, etc., and specifically to a multi-layer modular steel filing cabinet. Background Technology
[0002] Multi-layer steel filing cabinets are document storage devices made primarily of cold-rolled steel sheets through precision manufacturing processes. They feature a multi-layer structure and are constructed from high-quality cold-rolled steel sheets, giving them strong resistance to pressure and deformation. They can withstand the weight of large amounts of documents, are not easily damaged, and have a long service life. They are widely used in offices of companies, enterprises, government agencies, schools, and other workplaces.
[0003] Most current filing cabinets have a fixed height. These cabinets have a fixed structure and limited functions, resulting in many limitations. Their spatial layout cannot be flexibly adjusted. If the type of documents changes or storage needs increase, it is difficult to adapt to the new scenario by adding or removing modules, which can easily lead to wasted space or insufficient storage. Furthermore, if the cabinet is damaged or its functions cannot meet the needs in the long run, the entire cabinet must be replaced, which is costly and wasteful of resources. They are difficult to adapt to the diverse needs of modern office environments for storage devices in terms of flexibility, functionality, and sustainability. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention provides a multi-layer modular steel filing cabinet that allows for free combination and assembly of the cabinets as needed. This enables the cabinet height to be increased or decreased according to the usage scenario, improving its applicability and space utilization. Furthermore, it allows for targeted replacement of specific parts of the cabinet, reducing maintenance costs.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a multi-layer combined steel filing cabinet, comprising two cabinets arranged vertically, with four insert rods fixedly connected to the upper side of each cabinet, and the four insert rods on the upper side of each cabinet arranged in a rectangular array. Each of the eight plugs has a limit socket on its left side, and the right side of each of the eight limit sockets extends through the eight plugs respectively. Both cabinets have four rod slots on their lower sides, and the eight rod slots are compatible with eight rods. Both cabinets are equipped with a connecting mechanism, and the upper cabinet can be connected and fixed together with the lower cabinet through the connecting mechanism. The connecting structures of the two connecting structures are the same. The connecting mechanism includes a sliding groove, two connecting grooves, four limiting grooves, two sliding blocks, four connecting blocks, four fixed inserts, a bidirectional screw, a rotating groove, a rotating rod, two control blades, and two limiting rods.
[0006] Preferably, each of the two cabinets has a mounting groove on its left side, and a drawer is slidably connected inside each mounting groove. A handle is fixedly connected to the left side of each of the two drawers.
[0007] Preferably, the sliding groove is formed inside the cabinet and is located on the lower side of the bottom wall of the mounting groove; Both connecting slots are formed on the top wall of the sliding slot, and the two connecting slots are respectively set on the front and rear sides of the mounting slot.
[0008] Preferably, the two connecting slots are respectively connected to the four insertion slots, and the four limiting slots are respectively opened on the left and right sides of the four insertion slots that are far apart from each other; Both sliding blocks are slidably connected inside the sliding groove.
[0009] Preferably, the two sliding blocks are arranged symmetrically from left to right, and four connecting blocks are fixedly connected to the upper side of the two sliding blocks respectively; Four connecting blocks are slidably connected inside the two connecting slots, and four fixed plugs are fixedly connected to the left and right sides of the four connecting blocks, which are far apart from each other.
[0010] Preferably, the four fixing blocks are respectively adapted to the four limiting sockets and the four limiting grooves to form a plug-in fixing; The bidirectional screw is rotatably connected to the right wall of the sliding groove, and the thread at the left end of the bidirectional screw passes through the two sliding blocks.
[0011] Preferably, the rotating groove is located on the left side of the cabinet, the rotating rod is installed inside the rotating groove, and the right end of the rotating rod extends into the sliding groove.
[0012] Preferably, the right end of the rotating rod is fixedly connected to the bidirectional screw, and both control blades are fixedly connected to the front and rear sides of the outer surface of the rotating rod; Both control blades are located inside the rotating groove, and both limit rods are fixedly connected to the right wall of the sliding groove.
[0013] Preferably, the two limiting rods are arranged symmetrically front to back, and the left ends of the two limiting rods slide through the two sliding blocks, and the left ends of the two limiting rods are fixedly connected to the left wall of the sliding groove.
[0014] Compared with the prior art, the present invention provides a multi-layer modular steel filing cabinet, which has the following beneficial effects: (1) The multi-layer modular steel filing cabinet can be freely combined and spliced as needed, so that the height of the filing cabinet can be increased or decreased according to the usage scenario, which improves the applicability of the filing cabinet and also increases the space utilization rate of the filing cabinet in the scenario.
[0015] (2) When the two sliding blocks move, the two limit rods will restrict the movement of the two sliding blocks, thereby preventing the front and rear sides of the two sliding blocks from tilting, thus ensuring the stability of the connection structure.
[0016] (3) The limiting groove of this multi-layer modular steel filing cabinet can strengthen the connection between the fixing block and the rod, making the connection more stable; it can also prevent the rod from shaking in the rod groove, improve the overall stability of the filing cabinet, reduce component wear, extend service life, and ensure the safe and reliable use of the filing cabinet.
[0017] (4) This multi-layer modular steel filing cabinet can be freely combined and assembled, and the height of the cabinet can be adjusted according to the specific scenario. Where the space height allows, increasing the number of cabinet layers can make full use of vertical space and reduce the area occupied on the ground.
[0018] (5) This multi-layer modular steel filing cabinet allows for targeted replacement of the cabinet when a part of it is damaged. Since the filing cabinet is composed of multiple independent cabinets, it does not require the entire cabinet to be replaced as in traditional fixed filing cabinets; only the damaged cabinet needs to be replaced, greatly reducing maintenance costs.

[0025] Please see Figures 1 to 6 This invention provides a new technical solution: a multi-layer modular steel filing cabinet, comprising two cabinet bodies 1 arranged vertically. Each cabinet body 1 has a mounting groove 2 on its left side, and drawers 3 are slidably connected inside each mounting groove 2. Handles 4 are fixedly connected to the left side of each drawer 3. Four insert rods 5 are fixedly connected to the upper side of each cabinet body 1. The four insert rods 5 on the upper side of each cabinet body 1 are arranged in a rectangular array. Limiting sockets 6 are provided on the left side of each of the eight insert rods 5, and the right side of each of the eight limiting sockets 6 extends through the eight insert rods 5. Each cabinet 1 has four insertion slots 7 on its lower side, and the eight insertion slots 7 are compatible with the eight insertion rods 5. Both cabinets 1 are equipped with a connecting mechanism. The upper cabinet 1 can be connected and fixed together with the lower cabinet 1 through the connecting mechanism. The connecting structures of the two connecting structures are the same. The following description focuses on the upper connecting mechanism. The connecting mechanism includes a sliding groove 8, two connecting grooves 9, four limiting grooves 10, two sliding blocks 11, four connecting blocks 12, four fixing blocks 13, a bidirectional screw 14, a rotating groove 15, a rotating rod 16, two control blades 17, and two limiting rods 18.
[0026] Furthermore, the sliding groove 8 is formed inside the cabinet 1, and is located on the lower side of the bottom wall of the mounting groove 2. Two connecting grooves 9 are formed on the top wall of the sliding groove 8, respectively located on the front and rear sides of the mounting groove 2. The two connecting grooves 9 are connected to the four insertion rod grooves 7. Four limiting grooves 10 are formed on the left and right sides of the four insertion rod grooves 7, respectively, at a distance from each other. Two sliding blocks 11 are slidably connected inside the sliding groove 8, and are arranged symmetrically from left to right. Four connecting blocks 12 are fixedly connected to the upper side of the two sliding blocks 11, and are slidably connected inside the two connecting grooves 9. Four fixed insertion blocks 13 are fixedly connected to the left and right sides of the four connecting blocks 12, respectively, at a distance from each other. The four fixed insertion blocks 13 are connected to the four limiting insertion ports 6 and the four limiting... The slots 10 are fitted together to form a plug-in fixed connection. The bidirectional screw 14 is rotatably connected to the right wall of the sliding groove 8. The left end of the bidirectional screw 14 is threaded through the two sliding blocks 11. The rotating groove 15 is opened on the left side of the cabinet 1. The rotating rod 16 is installed inside the rotating groove 15. The right end of the rotating rod 16 extends into the interior of the sliding groove 8. The right end of the rotating rod 16 is fixedly connected to the bidirectional screw 14. The two control blades 17 are fixedly connected to the front and rear sides of the outer surface of the rotating rod 16. The two control blades 17 are both set inside the rotating groove 15. The two limit rods 18 are fixedly connected to the right wall of the sliding groove 8. The two limit rods 18 are symmetrically arranged front and rear. The left ends of the two limit rods 18 slide through the two sliding blocks 11. The left ends of the two limit rods 18 are fixedly connected to the left wall of the sliding groove 8.
[0027] Furthermore, when starting work, if it is necessary to combine the two cabinets 1, firstly, the two control blades 17 drive the rotating rod 16 to rotate. The rotating rod 16 then drives the two threaded sliding blocks 11 to move towards their opposite faces. The two sliding blocks 11 then drive the four connecting blocks 12 to move towards their opposite faces simultaneously. The four connecting blocks 12 then drive the four fixed inserts 13 to move simultaneously. Finally, all four fixed inserts 13 move into the connecting slots 9, allowing the two cabinets 1 to be combined. The upper cabinet 1 is then placed on top of the lower cabinet 1. At this point, the four inserts 5 of the lower cabinet 1 move into the four insert slots 7 of the upper cabinet 1 respectively. Then, the two control blades 17 drive the rotating rod 16 to rotate in the opposite direction. As mentioned above, the four fixed plugs 13 will move into the four plug slots 7 respectively. Then, the four fixed plugs 13 will pass through the four limiting plugs 6. Finally, a part of the four fixed plugs 13 will move into the four limiting slots 10. Then, the four plugs 5 can be limited and fixed inside the four plug slots 7, thus completing the combination of the two cabinets 1. When the two sliding blocks 11 move, the two limiting rods 18 will restrict the movement position of the two sliding blocks 11, thereby preventing the front and rear sides of the two sliding blocks 11 from tilting, thus ensuring the stability of the connection structure plug-in fixation.
[0028] Furthermore, this method allows for the free combination and assembly of filing cabinets as needed, enabling the height of the cabinets to be increased or decreased according to the usage scenario. This improves the applicability of the filing cabinets, increases the space utilization rate of the cabinets in the scenario, and allows for targeted replacement of specific parts of the cabinet, reducing the maintenance costs.
