Description

Technical Field

[0001] This utility model belongs to the field of folding cabinet technology, and in particular relates to a sliding folding cabinet and a combination cabinet. Background Technology

[0002] To reduce transportation costs, current containers are mostly transported as individual panels, then reassembled upon arrival at the destination. However, this design, with its numerous components and cumbersome assembly procedures, requires assemblers to rely on detailed instructions, which is not only time-consuming and labor-intensive, but also makes some containers difficult to disassemble once assembled, affecting their reusability. To address this issue, foldable containers have emerged on the market. Their ingenious design involves hinges connecting the side panels to the front and rear panels to form a frame. The foldable feature in the middle of the side panels effectively shortens the distance between the front and rear panels, significantly reducing the container's volume. Nevertheless, these foldable containers still face challenges such as numerous connecting parts and complex structures, requiring further optimization and innovation. Utility Model Content

[0003] To address the shortcomings of existing technologies, a sliding folding cabinet with a simpler structure and easier assembly is provided.

[0004] This utility model is achieved using the following technical solution: A sliding folding cabinet includes a base, four side panels, and a top panel. The lower ends of the four side panels are all hinged to the base. The four side panels include two oppositely arranged sliding side panels and two oppositely arranged flip side panels. The hinge position of the sliding side panels to the base is higher than the hinge position of the flip side panels to the base. The upper end of the sliding side panel is provided with at least one sliding member that slides with the top panel. The sliding member includes an extension section and a convex shaft at the end of the extension section. The bottom center of the top panel is provided with a groove extending along the line connecting the two sliding side panels. The convex shaft is slidably fitted in the groove, and the groove restricts the vertical position of the convex shaft.

[0005] When folding, the user first flips the two rotating side panels inwards, then flips the two sliding side panels inwards. As the sliding side panels flip, their convex shafts slide within the top plate's grooves, causing the top plate to descend. Finally, when both sliding side panels are fully flat, the folded state is complete. To open, the user pulls up the top plate, providing initial support for the side panels. Then, the user applies force from the inside out to the side panels, vertically positioning them to support the top plate. Finally, the user flips up the two rotating side panels one by one, supporting the top plate – a very convenient process.

[0006] The hinge positions of the two flip-up side panels and the base may or may not have a height difference, depending on the relationship between the height of the flip-up side panel and the length or width of the base. If the height of the flip-up side panel is greater than half the length or width of the base, then the hinge positions of the two flip-up side panels and the base need to have a height difference; otherwise, no height difference is required.

[0007] The slider is located at the upper end of the sliding side plate. It can be two or three sliders spaced apart, or it can be a single slider with a relatively long length. In this design, the slider is only located at the upper end of the sliding side plate, excluding the case where the slider is located on both sides of the sliding side plate.

[0008] In the above-mentioned scheme, the middle part of the sliding member has an extension section extending outward to the outside of the sliding side plate, and the extension section is provided with a convex shaft to achieve sliding engagement with the groove of the top plate, thereby realizing the linkage between the top plate and the sliding side plate.

[0009] In this design, all four side panels are hinged to the base and can be directly flipped and stacked on top of the base. A linkage sliding structure is provided between the top panel and the sliding side panels, allowing the sliding side panels to automatically lower the top panel during folding. No additional connecting parts such as screws are required, resulting in a simple structure that facilitates folding and installation for users.

[0010] Preferably, the extension section is disposed at the upper middle part of the sliding side plate, and the extension section extends outward and is inclined.

[0011] The inclined design of the extension section prevents interference between the outer surface of the sliding side panel and the bottom of the top panel during folding, ensuring the sliding side panel remains completely horizontal after folding and making folding smoother for the user. The angle between the extension section and the outer surface of the sliding side panel is obtuse.

[0012] Preferably, when the sliding side plate and the flipping side plate are erected, the side wall of the flipping side plate abuts against the side wall of the sliding side plate to prevent the sliding side plate from flipping inward; both sides of the sliding side plate are provided with baffles extending toward the flipping side plate to prevent the flipping side plate from flipping inward.

[0013] The sliding side plate maintains its upright position by abutting against the flipping side plate, while a baffle restricts the flipping side plate, thus maintaining its upright position. When the flipping side plate flips from an inclined state to an upright state, the baffle undergoes elastic deformation, allowing the flipping side plate to flip over the baffle. Furthermore, this solution simplifies the structure by directly installing the baffle on the sliding side plate, and is also very convenient for users to operate.

[0014] Preferably, the lower end of the top plate is provided with a downwardly extending rim around its perimeter, and the lower end of the top plate is also provided with a number of downwardly extending reinforcing ribs. There is a distance between the reinforcing ribs and the rim to form a limiting groove. When the flip side plate is in an upright state, the upper end of the flip side plate is located in the limiting groove.

[0015] Because the sliding component and the sliding groove are respectively located in the middle of the sliding side plate and the top plate, space is reserved on both sides of the top plate to limit the tilting side plate. By forming a limiting groove between the reinforcing rib and the surrounding edge, the tilting side plate can be further restricted to maintain its upright state. The reinforcing rib can also be used to strengthen the top plate, thus achieving two technical effects.

[0016] Preferably, the portion of the reinforcing rib near the edge is provided with a guide portion, and the lower end of the guide portion is provided with a guide slope to guide the flip side plate when it is flipped outward.

[0017] The guide ramp allows the flip-up side panel to flip outward more effectively and eventually enter the limiting groove. The guide part can be formed by the downward extension of the reinforcing rib near the edge, or the guide ramp can be directly set below the reinforcing rib body.

[0018] Preferably, the top plate is provided with laterally extending handles on both sides corresponding to the sliding side plate. The handles are hollow and communicate with the sliding groove. When the sliding side plate is upright, the sliding member is located inside the handle.

[0019] Because the slider has an inclined extension, the handle can accommodate the extension. Furthermore, the handle extends laterally from the sliding side panel, so its outward protrusion facilitates the user in lifting the top panel when unfolding the folding cabinet.

[0020] Preferably, the base has two parallel long sides and two parallel short sides, the sliding side plate is disposed on the short side, and the height of the sliding side plate is less than half the length of the long side; the flip side plate is disposed on the long side, and there is a height difference between the hinge positions of the two flip side plates and the base.

[0021] The height of the sliding side panel is less than half the length of the long side to prevent the two sliding side panels from colliding when folded. The flip side panel is located on the long side, so its height is mostly more than half the length of the short side. Therefore, the height difference between the two flip side panels and the base at the hinge point allows the flip side panels to be stacked together without interference when flipped.

[0022] Preferably, the slide groove is provided with a stop part, which abuts against the convex shaft when the sliding side plate is placed flat on the base.

[0023] By setting up a stop, the top plate can be prevented from shaking when the sliding side plate is placed flat on the base.

[0024] Preferably, one of the four side panels serves as a door frame, and a door panel is hinged to the door frame.

[0025] The door panel is installed to allow items to be placed and retrieved.

[0026] A combination cabinet with the above-mentioned sliding folding cabinet includes at least two sliding folding cabinets arranged vertically, with the base of the upper sliding folding cabinet serving as the top plate of the lower sliding folding cabinet.

[0027] The base of the upper sliding folding cabinet serves as the top plate of the lower sliding folding cabinet, allowing each folding cabinet in the combination cabinet to be folded, which is very convenient.

[0028] Compared with the existing technology, the present invention has the advantages of simpler structure and easier assembly. Attached Figure Description

[0042] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0043] like Figures 1 to 3 As shown, this embodiment discloses a sliding folding cabinet, including a base 1, which is rectangular in shape. Each side of the base 1 is hinged with a side panel. The four side panels include two sliding side panels 2 arranged opposite each other on the left and right sides, and two flip-up side panels 3 arranged opposite each other front and back. A top plate 4 is provided above the four side panels. The hinge position of the sliding side panels 2 with the base 1 is higher than the hinge position of the flip-up side panels 3 with the base 1. The front and back sides of the base 1 are long sides, and the left and right sides are short sides. The sliding side panels 2 are located on the short sides, and the height of the sliding side panels 2 is less than half the length of the long sides. The hinge positions of the two sliding side panels 2 with the base 1 are at the same height. The flip-up side panels 3 are located on the long sides, and the height of the flip-up side panels 3 is greater than half the length of the short sides. There is a height difference between the hinge positions of the two flip-up side panels 3 with the base 1. The front flip-up side panel 3 serves as the door frame 5, and the door frame 5 is hinged to the door panel 51. The door frame 5 is provided with a socket 52, and the door panel 51 is provided with a pin that is inserted into the socket 52. Alternatively, in some embodiments, the door frame 5 and the door panel 51 can be fixed together by a buckle or a magnet.

[0044] like Figure 3 , Figures 6 to 8As shown, a sliding member 6 is provided at the upper center of the sliding side plate 2. The sliding member 6 extends in the front-to-back direction and includes an extension section 61 extending outward from the sliding side plate 2 and a convex shaft 62 located at the end of the extension section 61. The extension section 61 is inclined and forms an obtuse angle with the outer surface of the sliding side plate 2. A groove 7 extending in the left-to-right direction is provided at the center of the bottom of the top plate 4. The groove 7 consists of two opposing L-shaped plates 72 located below the top plate 4, extending in the left-to-right direction, with their openings forming the groove 7. A stop part 71 is provided in the middle of the groove 7. When the sliding side plate 2 is placed flat on the base 1, the stop part 71 abuts against the convex shaft 62, preventing the top plate 4 from sliding. In this embodiment, the stop part 71 is approximately elliptical. In other embodiments, the stop part 71 can also be a protrusion, a bump, etc. The top plate 4 is provided with laterally extending handles 45 on the left and right sides corresponding to the sliding side plate 2. The handles 45 are hollow and connected to the slide groove 7. When the sliding side plate 2 is upright, the sliding member 6 is located inside the handle 45.

[0045] like Figures 3 to 5 As shown, when the sliding side plate 2 and the flipping side plate 3 are upright, the side wall of the flipping side plate 3 abuts against the inner side wall of the sliding side plate 2 to prevent the sliding side plate 2 from flipping inward. Both sides of the sliding side plate 2 are provided with baffles 21 extending towards the flipping side plate 3. The baffles 21 can elastically deform and are used to prevent the flipping side plate 3 from flipping inward. A downwardly extending rim 41 is provided around the lower end of the top plate 4. The lower end of the top plate 4 is also provided with several downwardly extending reinforcing ribs 42. There is a distance between the reinforcing ribs 42 and the rim 41 to form a limiting groove 44. When the flipping side plate 3 is upright, the upper end of the flipping side plate 3 is located within the limiting groove 44. The portion of the reinforcing rib 42 near the rim 41 has a downwardly extending guide portion 43. The lower end of the guide portion 43 has a guide slope that guides the flipping side plate 3 when it flips outward. The guide portion 43 is part of the reinforcing rib 42 and is integrally formed.

[0046] like Figures 9 to 11 As shown, in actual use, when folding is required, the user can grasp the handle 45 to lift the top plate 4 upwards and push the sliding side plate 2 outwards, while simultaneously applying force inwards to the flip side plate 3, causing the flip side plate 3 to disengage from the baffle 21 and the limiting groove 44, allowing the flip side plate 3 to flip and lie flat on the base 1. After folding both flip side plates 3, the user can apply force inwards to the sliding side plate 2, causing it to fold and lower the top plate 4, thus completing the final folding. When unfolding the folding cabinet, first pull up the top plate 4, causing the sliding side plate 2 to rotate outwards, and apply outward force to the sliding side plate 2, making it upright and supporting the top plate 4. Then, flip the flip side plates 3 one by one, allowing them to be limited by the baffle 21 and the limiting groove 44, thus achieving the final unfolding.

[0047] like Figure 12 As shown, Figure 12 This is a combination cabinet with two sliding folding cabinets arranged vertically, with the base 1 of the upper sliding folding cabinet serving as the top plate of the lower sliding folding cabinet. The folding and unfolding methods are the same as those used for a single folding cabinet.
