Description

Technical Field

[0001] This invention relates to the field of locker technology, and more particularly to a rotatable multi-layer steel locker. Background Technology

[0002] Storage refers to the act of storing items in an orderly manner for easy management and retrieval, and is widely used in homes, offices, warehouses, and other places. Effective storage solutions can improve space utilization and maintain a tidy environment.

[0003] Storage cabinets offer diverse storage options, and as one type of storage container, they are corrosion-resistant, waterproof, and suitable for various environments. The specifications and styles of storage cabinets can be customized to meet specific needs, featuring a simple design and environmentally friendly electrostatic spraying for durability. They typically open outwards for easy access to items.

[0004] When lockers are used for storage, they are designed with multiple drawers to categorize and store items. However, in practical applications, the drawers are often arranged in a matrix, which is quite dense. This can lead to situations where multiple people are obstructing the operation of the lockers when retrieving or storing items. While a rotating locker (publication number CN114043442B) can move the storage box containing the item to a specific retrieval location from a fixed position, making the structure more compact, it still highlights the aforementioned technical problems to some extent.

[0005] Therefore, how to provide a rotatable multi-layer steel locker is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] One objective of this invention is to provide a rotatable multi-layer steel locker to solve the problem that in practical applications of existing lockers, the number of drawers is arranged in a matrix and is relatively dense, which causes multiple people to be obstructed and have their operations severely affected when multiple people are retrieving or storing items.

The outer part of the second support shaft is pinned to a limit bushing. Guide grooves are provided on the bottom and top inner walls of the second storage slot away from the first storage slot. The limit bushing is slidably connected inside the guide groove. The side rotating drawer rotates around the second support shaft and extends out from the inside of the side window.

[0013] Preferably, two strong magnets are embedded in one corner of the back of the side pull-out drawer near the second storage slot, and one end of the two limiting arc strips corresponds to the two strong magnets and attracts each other.

[0014] Preferably, a handle storage groove is provided on the surface of the side rotating drawer away from the first storage groove. A movable handle is provided inside the handle storage groove. A first support shaft is inserted into the end of the movable handle near the front of the side rotating drawer. An installation slot is provided inside the end of the movable handle near the front of the side rotating drawer. A torsion spring is provided inside the installation slot. The torsion spring is sleeved to the outside of the first support shaft. Both ends of the first support shaft are inserted into the interior of the storage cabinet body through the second storage groove.

[0015] Preferably, a pad is welded to the side wall of the handle storage slot, and the movable handle is controlled by a torsion spring in the mounting slot to rotate around the first support shaft and abut against the surface of the pad, so that the movable handle is stored inside the handle storage slot.

[0016] Preferably, the two main storage cabinets are used together and are provided with the same top support. A back panel is assembled and connected to the bottom of the back of the top support. A storage cabinet support facing the front is assembled at the bottom of the back panel. A linkage control component is provided between the bottoms of the two main storage cabinets.

[0017] Preferably, the linkage control component includes a U-shaped motor bracket, a geared motor is mounted on the top inner wall of the motor bracket, one end of the geared motor passes through the interior of the motor bracket from bottom to top and is mounted on a drive gear, and two opposing driven racks are meshed on the outer side of the drive gear; a motor storage slot is provided at the bottom corner of the junction of the two main storage cabinets, the interior of the motor storage slot is connected to the interior of the recessed groove, and the motor bracket, geared motor and drive gear are stored inside the motor storage slot.

[0018] Preferably, the tops of both driven racks are fitted with rack brackets, and the bottom of the main body of the storage cabinet has a recessed groove; one end of the rack bracket is fitted to the inner wall of the top of the recessed groove on one main body of the storage cabinet through a strip-shaped gasket, while the other end of the rack bracket extends to the inner side of the recessed groove on the other main body of the storage cabinet.

[0019] Preferably, the top of the storage cabinet support is provided with a recessed groove, and the bottom of the storage cabinet body is provided with a rib groove located on the front of the recessed groove and connected thereto. A limiting rib is welded to the front of the top of the storage cabinet support; the storage cabinet body is slidably connected to the outside of the limiting rib through the rib groove.

[0020] Preferably, multiple rollers are assembled and connected to the two long sides of the bottom of the main body of the locker. The multiple rollers are arranged in a straight line and roll on the bottom inner wall of the recessed groove.

[0021] The beneficial effects of this invention are:

[0022] I. This invention combines a side drawer with a first arc-shaped upright plate and a side rotating drawer with a second arc-shaped upright plate to form a side drawer structure. The first and second arc-shaped upright plates are connected by two limiting arc strips machined to the outer surface of the second arc-shaped upright plate and two limiting arc grooves opened inside the first arc-shaped upright plate. When a person places their finger inside the handle storage groove, they can control the movable handle to rotate around the first support shaft, tightening the torsion spring. This allows the side rotating drawer to rotate around the second support shaft, causing the side rotating drawer and the second arc-shaped upright plate to extend from the side window. This facilitates independent storage and retrieval of items from both sides and the front of the main body of the locker, expanding the operable range of the device, accommodating multiple people to store and retrieve items, improving the efficiency of item storage and retrieval, and greatly reducing the problem of multiple people being hindered from operating due to their body position.

[0023] Second, the present invention enables the movable handle to rotate around the first support shaft under the control of the torsion spring in the mounting slot. When the movable handle is against the surface of the pad, and when the movable handle is stored in the handle storage slot, it can support the side pull-out drawer and the side rotating drawer to exit normally in front in the second storage slot, without the movable handle blocking the movement of the side pull-out drawer and the side rotating drawer.

[0024] Third, this invention controls the rotation of the drive gear by a reduction motor, which drives two driven racks to move in opposite directions. This causes the main body of the storage cabinet, which is respectively assembled and fixed to the two rack supports, to move away from each other with the support of multiple rollers and the cooperation of limiting ribs and rib grooves, rollers and recessed grooves. This releases the space in the contact area between the two adjacent storage cabinet bodies, ensuring that the two storage cabinet bodies in the combined use state will not reduce the standing position and operating space of the personnel due to the contact area.

[0042] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0043] Example 1:

[0044] The technical solution in this application embodiment addresses the problem that, in practical applications of the aforementioned lockers, the drawers are arranged in a matrix, which is quite dense. This causes significant operational difficulties when multiple people are accessing or storing items, as their positions obstruct the flow of traffic. The overall approach is as follows:

[0045] To address the problems existing in the prior art, the present invention provides a schematic diagram of a rotatable multi-layer steel storage cabinet, as shown below. Figures 1 to 7 As shown, the main body of the storage cabinet 2, multiple central drawers 9 and multiple side drawer structures 3 are provided. The interior of the main body of the storage cabinet 2 is provided with multiple first storage slots 14, multiple second storage slots 15 and multiple side windows 4. The multiple second storage slots 15 are arranged in two rows and are located on both sides of the multiple first storage slots 14 arranged in one row. The multiple side windows 4 are all located on the side of the second storage slots 15 away from the first storage slots 14 and are connected to the interior of the multiple second storage slots 15.

[0046] The side drawer structure 3 includes a side pull-out drawer 301 and a side rotating drawer 302. The back of the side pull-out drawer 301 is integrally formed with a first arc-shaped upright plate 303, and the front of the side rotating drawer 302 is integrally formed with a second arc-shaped upright plate 304. The outer surface of the second arc-shaped upright plate 304 is integrally formed with two limiting arc strips 306, and the inner surface of the first arc-shaped upright plate 303 is provided with two limiting arc grooves 18.

[0047] Among them, multiple central drawers 9 are neatly arranged in the vertical direction and located at the center of the main body 2 of the storage cabinet, while multiple side drawer structures 3 are arranged in two rows and symmetrically on both sides of the central drawers 9, that is, located at the edge of the main body 2 of the storage cabinet.

[0048] Secondly, by making the height of the back of the side pull-out drawer 301 the same as the height of the side rotating drawer 302, the side drawer structure 3 can maintain the shape of a regular drawer. The height of the first arc-shaped upright plate 303 and the second arc-shaped upright plate 304 is the same and less than the height of the side rotating drawer 302. This allows the items stored inside the side drawer structure 3 to be stored in sections between the side rotating drawer 302 and the side pull-out drawer 301, and the two sections contain the same type of item.

[0049] Meanwhile, multiple central drawers 9 are slidably connected to the interior of multiple first storage slots 14, and side pull-out drawers 301 carrying side rotating drawers 302 are slidably connected to the interior of second storage slots 15. By making the curvature of the first arc-shaped upright plate 303 the same as that of the second arc-shaped upright plate 304, and by making the two limiting arc strips 306 slidably connected to the interior of the two limiting arc grooves 18, when the side rotating drawer 302 is rotated under the guidance of the limiting arc strips 306 and the limiting arc grooves 18 and is movably connected to the interior of the side window 4, items stored inside the side rotating drawer 302 can be removed from the interior of the side window 4, which is convenient for multiple people to access items from both sides of the main body 2 of the locker. When the side drawer structure 3 is not pulled out from the front of the second storage slot 15, it can support multiple people to access items from the front of the central drawers 9 in the same row. Therefore, it greatly increases the position available for operation, improves the efficiency of accessing items, and greatly reduces the problem of multiple people being affected by their body position.

[0050] like Figures 2 to 6 As shown, drawer slide assemblies 13 are assembled and connected between the two sides of the central drawer 9 and the inner walls of the two sides of the first storage slot 14, and between one side of the side pull-out drawer 301 and the inner wall of the second storage slot 15 near the first storage slot 14. The top and bottom of the back of the side rotating drawer 302 away from the first storage slot 14 are integrally formed with a second support shaft 12. The outer pin of the second support shaft 12 is connected to a limit bushing 11. The bottom and top inner walls of the second storage slot 15 away from the first storage slot 14 are provided with guide grooves 10.

[0051] In this way, by sliding the limiting bushing 11 inside the guide bar groove 10, the side pull-out drawer 301 and the side rotating drawer 302 can be supported as a whole to be pulled out from inside the second storage groove 15 to the front, so as to ensure that it has the same push-pull function as the central drawer 9.

[0052] Meanwhile, by rotating the side-side rotating drawer 302 around the second support shaft 12, support can be provided for the side-side rotating drawer 302 to rotate inside the second storage slot 15. Under the guidance of the limiting arc strip 306 and the limiting arc groove 18, it extends out from the inside of the side window 4, providing convenience for people to store and retrieve items.

[0053] Secondly, to ensure the stability of the side pull-out drawer 301 and the side rotating drawer 302 when connected together and combined into a structure similar to the central drawer 9, such as Figure 6 and Figure 7 As shown, two strong magnets 310 are embedded in one corner of the back of the side pull-out drawer 301 near the second storage slot 15. By making one end of the two limiting arc strips 306 correspond to the two strong magnets 310 and attract each other, when the side rotating drawer 302 is not controlled to rotate around the second support shaft 12, the side pull-out drawer 301 and the side rotating drawer 302 can form a rectangle by means of the attraction between one end of the limiting arc strips 306 and the strong magnets 310, thus maintaining the shape of a regular drawer.

[0054] Furthermore, to facilitate control of the side rotating drawer 302 rotating around the second support shaft 12, it extends from inside the side window 4, such as... Figure 4 and Figure 5 As shown, a handle storage groove 16 is provided on the side surface of the side rotating drawer 302 away from the first storage groove 14. A movable handle 305 is provided inside the handle storage groove 16. The first support shaft 307 is inserted into the end of the movable handle 305 near the front of the side rotating drawer 302. An installation slot 17 is provided inside the end of the movable handle 305 near the front of the side rotating drawer 302. A torsion spring 308 is provided inside the installation slot 17. The torsion spring 308 is sleeved to the outside of the first support shaft 307. The two ends of the first support shaft 307 are inserted into the interior of the main body 2 of the storage cabinet through the second storage slot 15. When the movable handle 305 is controlled by the torsion spring 308 in the mounting slot 17 and rotates around the first support shaft 307 and is stored in the handle storage slot 16, it can support the side pull-out drawer 301 and the side rotating drawer 302 to exit to the front inside the second storage slot 15. The movable handle 305 will not protrude from the surface of the side rotating drawer 302 and block the movement of the side pull-out drawer 301 and the side rotating drawer 302.

[0055] At the same time, by controlling the movable handle 305 to rotate around the first support shaft 307 to tighten the torsion spring 308, a control point can be provided for the personnel to control the side rotating drawer 302 to rotate around the second support shaft 12 and exit from the inside of the side window 4.

[0056] Furthermore, to facilitate placing fingers inside the handle storage slot 16, the end of the control handle 305 away from the first support shaft 307 is retracted from the handle storage slot 16 and rotates around the first support shaft 307, as shown below. Figure 5As shown, a pad 309 is welded to the side wall of the handle storage groove 16. The movable handle 305 is controlled by the torsion spring 308 in the mounting slot 17 and rotates around the first support shaft 307 to abut against the surface of the pad 309, so that the movable handle 305 is stored inside the handle storage groove 16. A gap can be made between the movable handle 305 and the side wall of the handle storage groove 16, which provides convenience for fingers to be placed inside the handle storage groove 16 to control the movable handle 305.

[0057] In this embodiment, a side drawer structure 3 is formed by combining a side pull-out drawer 301 with a first arc-shaped upright plate 303 and a side rotating drawer 302 with a second arc-shaped upright plate 304. The first arc-shaped upright plate 303 and the second arc-shaped upright plate 304 are connected by two limiting arc strips 306 machined to the outer surface of the second arc-shaped upright plate 304 and two limiting arc grooves 18 opened inside the first arc-shaped upright plate 303. When a person places their finger inside the handle storage groove 16, they can control the movable handle 305 to rotate around the first support shaft 307, tighten the torsion spring 308, and control the side rotating drawer 302 to rotate around the second support shaft 12, so that the side rotating drawer 302 and the second arc-shaped upright plate 304 extend out from the side window 4, which is conducive to independently storing and retrieving items on both sides and the front of the main body of the locker 2 as needed.

[0058] Meanwhile, when the side rotating drawer 302 and the side pull-out drawer 301 are combined into a rectangular state, they maintain the same shape as the central drawer 9. With the help of the drawer slide assembly 13 to guide the side pull-out drawer 301, and the limiting bushing 11 outside the second support shaft 12 sliding inside the guide groove 10, the side drawer structure 3 can be pulled forward, so that the side pull-out drawer 301 and the side rotating drawer 302 can be pulled out from the inside of the second storage groove 15 to the front, which helps to maintain its normal function.

[0059] Therefore, when multiple central drawers 9 are pulled out from inside the first storage slot 14 to the front, and the side rotating drawer 302 rotates around the second support shaft 12 and extends out from inside the side window 4, the operable range of the device can be expanded, which is conducive to accommodating multiple people to store and retrieve items, greatly increasing the operable position of the personnel, improving the efficiency of storing and retrieving items, and greatly reducing the problem of multiple people being affected by their body position.

[0060] It is worth noting that the central drawer 9 or the side drawer structure 3 in the vertical direction must maintain sufficient gaps to ensure that when two adjacent central drawers 9 or two side drawer structures 3 are pulled out, items can be stored and retrieved inside the two central drawers 9 or two side drawer structures 3 at the same time.

[0061] Example 2:

[0062] Based on Example 1, this application's embodiment expands the storage space of the device without affecting multiple people's access to items. The overall concept is as follows:

[0063] like Figure 1 , Figure 3 , Figures 8 to 12 As shown, two storage cabinet bodies 2 are used together and are provided with the same top support 1. A back panel 22 is assembled and connected to the bottom of the back of the top support 1. A storage cabinet support 8 facing the front is assembled at the bottom of the back panel 22. A linkage control component is provided between the bottoms of the two storage cabinet bodies 2.

[0064] The linkage control component includes a U-shaped motor bracket 25. A geared motor 26 is assembled and connected to the top inner wall of the motor bracket 25. One end of the geared motor 26 passes through the interior of the motor bracket 25 from bottom to top and is assembled and connected to a drive gear 27. Two opposing driven racks 24 are meshed and connected to the outside of the drive gear 27. Motor storage slots 19 are provided at the bottom corners where the two storage cabinet bodies 2 meet. The interior of the motor storage slots 19 is connected to the interior of the recessed grooves 6. The motor bracket 25, the geared motor 26 and the drive gear 27 are stored inside the motor storage slots 19.

[0065] Each of the two driven racks 24 is fitted with a rack bracket 23 at the top. The bottom of the storage cabinet body 2 is provided with a recessed groove 6. One end of the rack bracket 23 is fitted to the inner wall of the top of the recessed groove 6 on one storage cabinet body 2 through a strip-shaped gasket, while the other end of the rack bracket 23 extends to the inner side of the recessed groove 6 on the other storage cabinet body 2. When the reduction motor 26 controls the drive gear 27 to rotate, it drives the two driven racks 24 to move in opposite directions. Since the rack brackets 23 on the two driven racks 24 are respectively fitted and fixed to the two storage cabinet bodies 2, the two storage cabinet bodies 2 can be moved away from each other, exposing the area between the two adjacent storage cabinet bodies 2 to the outside. This does not affect the side rotating drawer 302 in the adjacent area of ​​the two storage cabinet bodies 2 from the inside of the side window 4, thus ensuring the operable space of the two storage cabinet bodies 2 in the combined state.

[0066] Secondly, to prevent the main body 2 of the locker from detaching from the top of the locker support 8 and to ensure that the two main bodies 2 are aligned, and to ensure that the driven rack 24 and the driving gear 27 are stably engaged, such as... Figures 9 to 12As shown, the top of the storage cabinet support 8 is provided with a recessed groove 5, and the bottom of the storage cabinet body 2 is provided with a rib groove 20 located on the front of the recessed groove 6 and connected to it. The front of the top of the storage cabinet support 8 is welded to a limiting rib 7. Multiple rollers 21 are assembled and connected to the two long sides of the bottom of the storage cabinet body 2. By arranging the multiple rollers 21 in a line and rolling them on the bottom inner wall of the recessed groove 5, the storage cabinet body 2 is slidably connected to the outside of the limiting rib 7 through the rib groove 20. By using the limiting rib 7 and the recessed groove 5 that is recessed to the bottom and the rollers 21, the front and back movement of the storage cabinet body 2 on the top of the storage cabinet support 8 can be restricted.

[0067] Meanwhile, to facilitate the control of the drive gear 27 by the geared motor 26, which drives the two driven racks 24 to move in opposite directions, the two storage cabinet bodies 2 are moved away from or closer to each other, such as... Figure 11 and Figure 12 As shown, multiple rollers 21 are assembled and connected to the two long sides of the bottom of the main body 2 of the locker. By arranging the multiple rollers 21 in a straight line and rolling them on the bottom inner wall of the recessed groove 5, the resistance of the main body 2 of the locker when moving on the top of the locker support 8 can be reduced.

[0068] In this embodiment, the drive gear 27 is rotated by the reduction motor 26, which drives the two driven racks 24 to move in opposite directions. This causes the storage cabinet bodies 2, which are respectively assembled and fixed with the two rack supports 23, to move away from each other under the support of multiple rollers 21 and the cooperation of the limiting ribs 7 and rib grooves 20, rollers 21 and recessed grooves 5. This releases the space in the contact area between the two adjacent storage cabinet bodies 2, and does not affect the side rotating drawers 302 in the adjacent area of ​​the two storage cabinet bodies 2 from the inside of the side window 4. This ensures that the two storage cabinet bodies 2 in the combined state have operable space, which is not affected by the two storage cabinet bodies 2 in the combined use state.

[0069] Specifically, when using this device to perform operations:

[0070] First, the reduction motor 26 is started, which drives the drive gear 27 to rotate. This causes the two driven racks 24 meshing with the drive gear 27 to move away from each other through the rack bracket 23. The two storage cabinet bodies 2 move under the support of multiple rollers 21 rolling on the inner wall of the bottom of the recessed groove 5. The movement of the storage cabinet bodies 2 is restricted by the cooperation of the limiting rib 7 and the rib slide 20, the rollers 21 and the recessed groove 5, and the front and back movement of the storage cabinet bodies 2 on the top of the storage cabinet support 8. This exposes the area where the two storage cabinet bodies 2 meet to the outside, providing sufficient space for people to enter between the two storage cabinet bodies 2.

[0071] Then, guided by the two drawer slide assemblies 13, the center drawer 9 is pulled out from the inside of the first storage slot 14, exposing the space inside the center drawer 9 to the outside. On the other hand, guided by the sliding of the limiting bushing 11 outside the drawer slide assembly 13 and the second support shaft 12 inside the guide bar groove 10, the side drawer structure 3 is pulled out from the inside of the second storage slot 15 (in this state, the movable handle 305 is controlled by the torsion spring 308 in the mounting slot 17. When it rotates around the first support shaft 307 and is stored inside the handle storage slot 16, the support side pull-out drawer 301 and the side rotating drawer 302 are pulled out to the front inside the second storage slot 15). This allows the space inside the side drawer structure 3 to be exposed to the front of the cabinet body 2, so as to maintain the normal state of the device.

[0072] Meanwhile, when the side drawer structure 3 is inside the second storage slot 15, placing a finger inside the handle storage slot 16 controls the movable handle 305 to rotate around the first support shaft 307, tightening the torsion spring 308, and controlling the side rotating drawer 302 to rotate around the second support shaft 12, causing the side rotating drawer 302 and the second arc-shaped upright plate 304 to extend from the side window 4, allowing items to be stored and retrieved on both sides of the main body 2 of the locker. This provides more people with standing positions and operating space for storing and retrieving items, improving the efficiency of storing and retrieving items and greatly reducing the problem of multiple people being hindered from operating due to their body position.

[0073] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
