Description

Technical Field

[0001] This invention belongs to the field of storage cabinet technology, specifically a foldable steel cabinet that can be quickly assembled and disassembled. Background Technology

[0002] Traditional steel cabinets are typically connected by welding or bolts, resulting in a sturdy overall structure but a bulky size that is inconvenient to handle and transport. In applications such as logistics warehousing, temporary offices, and outdoor operations, users often need a cabinet that can be quickly unfolded for use and folded away for storage after use, in order to save transportation space and warehousing costs.

[0003] Existing technologies include some foldable cabinet designs, such as those using hinged side panels for folding. However, these folding mechanisms are typically complex and cumbersome to operate, and their unfolded structure lacks rigidity and stability. Furthermore, existing foldable cabinets have limited height adjustment capabilities, making it difficult to adapt to the different height requirements of stored items. Summary of the Invention

[0004] To address the above problems, the present invention provides the following technical solution: A folding steel cabinet that allows for quick assembly and disassembly, comprising: The base plate, top plate, scissor lift frame, upper panel, lower panel, and end folding door panel; The bottom plate and the top plate are arranged parallel to each other and opposite to each other, and the upper surface of the bottom plate and the lower surface of the top plate are respectively provided with slide rails along their length direction; The scissor lift includes two support arms that are hinged together in the middle. Each support arm has a slider hinged to its end. The slider is slidably embedded in the slide rail. The scissor lift is used to adjust the vertical distance between the bottom plate and the top plate by changing its unfolding angle. The top plate is hinged to the upper surrounding plate on both sides along its length. The bottom plate is hinged to the lower enclosure plate on both sides along its length. A detachable fixing structure is provided between the free end of the lower enclosure plate and the free end of the upper enclosure plate, which is used to fix the upper enclosure plate and the lower enclosure plate in the unfolded state to form the main side wall of the cabinet. The end folding door panel is hinged to both sides of the cabinet in the width direction, including an upper door panel and a lower door panel that are hinged to each other. The end folding door panel is used to close the side wall of the cabinet in the width direction and bends inward to store when the cabinet is folded.

[0005] As a further improvement to the above technical solution: The slide rail is recessed and has a ball groove, and the slider is fitted with balls that roll in cooperation with the ball groove.

[0006] Furthermore, an angle lock is provided at the middle hinge point of the scissor lift frame. The angle lock is connected to the hinge shafts of the two support arms by a threaded connection and is used to lock the unfolding angle of the scissor lift frame by tightening when the cabinet is unfolded to a predetermined height.

[0007] Furthermore, the detachable fixing structure is a magnetic hook and loop assembly, which includes a first magnetic block embedded in the free end of the upper panel and a second magnetic block embedded in the free end of the lower panel. The upper panel and the lower panel are fixedly connected in the unfolded state by the magnetic attraction of the first magnetic block and the second magnetic block.

[0008] Furthermore, a linear locking mechanism is provided on the outer side of the middle hinge position of the end folding door panel. The linear locking mechanism is used to lock the relative rotation between the upper door panel and the lower door panel when the end folding door panel is unfolded to a flat state.

[0009] Furthermore, the linear locking mechanism includes a locking slide plate and a guide slide groove, the guide slide groove being fixedly disposed on the outer edge of the lower door panel, and the locking slide plate being slidably disposed on the outer edge of the upper door panel; When the end folding door panel is in the unfolded state, the locking slide plate slides downward and inserts into the guide groove to restrict the upper door panel and the lower door panel from rotating relative to each other about their hinge axis.

[0010] Furthermore, the hinge axis of the upper panel is parallel to the length direction of the top plate, the hinge axis of the lower panel is parallel to the length direction of the bottom plate, and the upper panel and the lower panel are respectively attached to the upper surface of the top plate and the lower surface of the bottom plate in the folded state.

[0011] Furthermore, the top plate, the bottom plate, the upper enclosure plate, the lower enclosure plate, and the end folding door panel are all steel sheet metal parts.

[0012] Furthermore, there are two slide rails, which are symmetrically arranged on both sides of the width direction of the bottom plate and the top plate, and the scissor lifts are arranged in two sets, respectively located on both sides of the width direction of the cabinet.

[0013] Furthermore, the upper door panel of the end folding door panel is hinged to the width-direction side edge of the top plate, and the lower door panel is hinged to the width-direction side edge of the bottom plate, and is kept upright by the linear locking mechanism in the unfolded state.

[0014] Compared with the prior art, the beneficial effects of the present invention are: The cabinet height is infinitely adjustable and can be quickly raised and lowered using a scissor lift mechanism and sliding rails. An angle locker ensures that the cabinet remains locked at the predetermined height, flexibly adapting to the storage needs of items of different heights. The upper and lower panels are quickly joined using magnetic snap-fit ​​components, and the end folding doors are flattened and locked using a linear locking mechanism. The entire unfolding and folding process requires no tools and can be completed by a single person in seconds, greatly improving ease of use. Furthermore, in the folded state, each panel fits against the outer surface of the top and bottom panels, and the end folding doors fold inwards and are stored between the top and bottom panels, resulting in a flat overall shape that significantly reduces space occupation, facilitates stacking and long-distance transportation, and effectively reduces warehousing and logistics costs. Moreover, the use of steel sheet metal parts in conjunction with the scissor lift structure ensures the unfolded cabinet has excellent structural rigidity and load-bearing capacity. The panels do not interfere with each other and experience minimal wear during repeated folding and unfolding, guaranteeing the product's lifespan and reliability. Attached Figure Description

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention. Example

[0018] like Figure 1-4 As shown, the foldable steel cabinet of this embodiment, which can be quickly assembled and disassembled, includes: a base plate 1, a top plate 2, a scissor lift frame 3, an upper panel 4, a lower panel 5, and an end folding door panel 6. The bottom plate 1 and the top plate 2 are arranged parallel to each other and opposite to each other. The upper surface of the bottom plate 1 and the lower surface of the top plate 2 are respectively provided with slide rails 7 along their length. The scissor lift frame 3 includes two support arms 301 that are hinged together in the middle. Each support arm 301 has a slider 302 hinged to its end. The slider 302 is slidably embedded in the slide rail 7. The top plate 2 is hinged to the upper surrounding plate 4 on both sides along its length. The bottom plate 1 is hinged to the two sides along its length direction with a lower enclosure plate 5, and a detachable fixing structure 8 is provided between the free end of the lower enclosure plate 5 and the free end of the upper enclosure plate 4. The end folding door panel 6 is hinged to both sides of the cabinet in the width direction, including the upper door panel 601 and the lower door panel 602 that are hinged to each other. The end folding door panel 6 is used to close the side wall of the cabinet in the width direction.

[0019] The slide rail 7 has a recessed ball groove 701, and the slider 302 is fitted with balls 303 that roll in cooperation with the ball groove 701.

[0020] An angle locker 9 is provided at the middle hinge point of the scissor lift frame 3. The angle locker 9 is connected to the hinge shaft of the two support arms 301 by threaded connection. It is used to lock the unfolding angle of the scissor lift frame 3 by tightening when the cabinet is unfolded to the predetermined height.

[0021] The detachable fixing structure 8 is a magnetic hook and loop assembly. The magnetic hook and loop assembly includes a first magnetic block 801 embedded in the free end of the upper panel 4 and a second magnetic block 802 embedded in the free end of the lower panel 5. The upper panel 4 and the lower panel 5 are fixedly connected by magnetic attraction between the first magnetic block 801 and the second magnetic block 802 when the upper panel 4 and the lower panel 5 are unfolded.

[0022] A linear locking mechanism 10 is provided on the outer side of the middle hinge position of the end folding door panel 6. The linear locking mechanism 10 is used to lock the relative rotation between the upper door panel 601 and the lower door panel 602 when the end folding door panel 6 is unfolded to the plane state.

[0023] The linear locking mechanism 10 includes a locking slide plate 1001 and a guide slide groove 1002. The guide slide groove 1002 is fixedly disposed on the outer edge of the lower door panel 602, and the locking slide plate 1001 is slidably disposed on the outer edge of the upper door panel 601. When the end folding door panel 6 is in the unfolded state, the locking slide plate 1001 slides down and inserts into the guide slide groove 1002 to restrict the upper door panel 601 and the lower door panel 602 from rotating relative to each other around their hinge axis.

[0024] The hinge axis of the upper panel 4 is parallel to the length direction of the top panel 2, and the hinge axis of the lower panel 5 is parallel to the length direction of the bottom panel 1. In the folded state, the upper panel 4 and the lower panel 5 are respectively attached to the upper surface of the top panel 2 and the lower surface of the bottom panel 1.

[0025] The top panel 2, bottom panel 1, upper panel 4, lower panel 5, and end folding door panel 6 are all steel sheet metal parts.

[0026] There are two slide rails 7, which are symmetrically arranged on both sides of the width direction of the bottom plate 1 and the top plate 2, respectively. The scissor lift frame 3 is set in two sets, located on both sides of the width direction of the cabinet.

[0027] The upper door panel 601 of the end folding door panel 6 is hinged to the width-direction side edge of the top panel 2, and the lower door panel 602 is hinged to the width-direction side edge of the bottom panel 1. In the unfolded state, it is kept upright by the linear locking mechanism 10.

[0028] The usage process of the folding steel cabinet in this embodiment is as follows: Unfolding Operation: The initial state is the folded storage state. First, lift the top panel 2 upwards. The scissor lift 3 unfolds under the action of gravity and external force. The slider 302 slides inwards along the slide rail 7, and the top panel 2 gradually rises to the desired height. Then, tighten the angle lock 9 to lock the height. Next, flip the upper panel 4 downwards and the lower panel 5 upwards, so that the first magnetic block 801 and the second magnetic block 802 adhere to each other to form the main side wall. Then, unfold the end folding door panels 6 on both sides in the width direction outwards, so that the upper door panel 601 and the lower door panel 602 are flattened. Then, push the locking slide plate 1001 downwards into the guide groove 1002 to lock the end folding door panels 6. At this point, the cabinet is fully unfolded and ready for use.

[0029] Folding Operation: First, pull the locking slide plate 1001 upward from the guide groove 1002 to release the lock of the end folding door panel 6, and fold the upper door panel 601 and lower door panel 602 inward along the hinge axis. Then, overcome the magnetic attraction to separate the upper panel 4 and lower panel 5, and flip them outward to remove them from the vertical position. Finally, release the angle lock 9, press down the top plate 2, the scissor lift frame 3 retracts, the slider 302 slides outward along the slide rail 7, the top plate 2 descends to the lowest position, and the panels are stacked together to complete the folding and storage. Example

[0030] The difference between this embodiment and Embodiment 1 lies in the hinge method of the end folding door panel 6.

[0031] In this embodiment, the end folding door panel 6 is hinged only to the width-direction side edge of the top plate 2 via the top of its upper door panel 601, while the lower door panel 602 is a free end, meaning it is not directly hinged to the bottom plate 1. In the unfolded state, the upper door panel 601 and the lower door panel 602 are flattened and kept upright by the linear locking mechanism 10. At this time, the bottom end of the lower door panel 602 naturally abuts against or is slightly higher than the surface of the bottom plate 1, and the bending moment is borne by the linear locking mechanism 10, keeping the end folding door panel 6 upright overall.

[0032] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
