Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of cabinets, especially relates to a folding storage cabinet and combined cabinet. BACKGROUND

[0002] The storage box is a kind of container for arranging and storing scattered articles, and the folding storage box has two states in function: in the unfolded state to accommodate articles when in use, and in the folded state when storing or transporting, thereby significantly reducing the space occupied.

[0003] For example, Chinese patent application No. 202322105064.5 discloses an assembled storage box, which includes a box body and a door body. The box body is composed of a bottom plate, a top plate, a back plate and two side plates. A door frame is detachably installed on the front side. The upper and lower ends of the door body are hingedly connected to the upper and lower sides of the door frame. During transportation, the top plate and the door frame can be removed from the box body, and then the back plate and the side plates can be folded to reduce the overall volume of the storage box.

[0004] However, the existing technology has the following problems: the door frame needs to be disassembled every time it is transported, and needs to be reassembled when in use, which is cumbersome and reduces the efficiency. In addition, some combined cabinets in the prior art attempt to fold the door frame by rotating the door frame with the bottom plate, but this method requires a larger size of the base and a shorter door frame, otherwise it cannot meet the folding requirement. Especially for a combined cabinet with a high height, since the height of the door frame is much greater than the length or width of the base, the folding of the door frame is difficult to achieve. UTILITY MODEL CONTENTS

[0005] To solve the problems in the prior art, a folding storage cabinet is provided, which does not need to disassemble the door frame when folding.

[0006] The utility model adopts the following technical scheme to achieve: a folding storage cabinet, comprising a base, a back plate, a door frame, a top plate and two oppositely arranged side plates, the top plate is detachably arranged, the four periphery of the base extends upwardly with a hinge wall, the lower end of the back plate, the door frame and the two side plates are hingedly connected with the hinge wall of the base, and there is a height difference between the hinge positions of the four and the base, at least the back plate and the door frame have a self-foldable structure, the hinge position of the side plate and the base is higher than the hinge position of the door frame and the back plate and the base, the door frame comprises a door panel hingedly connected with the door frame, a first fixing structure and a second fixing structure for opening or closing the door panel are arranged between the door panel and the door frame, the door panel also has a self-foldable structure, and the folding pivot axis of the door panel is coaxially arranged with the folding pivot axis of the door frame.

[0007] When the storage cabinet is folded, the door panel is folded together with the door frame and stacked on the base with the back plate and the side plates.

[0008] When the storage cabinet needs to be folded, the top plate is first removed from above the entire storage cabinet, then the back plate and the door frame are folded and stacked on the base in turn, and then the two side plates are flipped or folded (if the side plates also have a folding structure) and stacked on the door frame or the back plate. At this time, the folding of the entire storage cabinet is completed.

[0009] The detachable setting of the top plate can be detachable with the side plates, or detachable with the back plate or the door frame. The detachable setting mode can adopt any existing detachable structure of the top plate of the existing folding storage cabinet.

[0010] The folding structure of the back plate and the door frame is the same as the folding structure of the existing folding storage cabinet, such as the back plate having an upper back plate and a lower back plate, and the upper back plate and the lower back plate being hingedly connected to realize the folding of the back plate itself.

[0011] The first fixing structure and the second fixing structure of the door plate can be fixed on the door frame in any existing structure, such as buckle fixing, magnet fixing, and pin fixing. When the storage cabinet is in use, the fixing of the door plate and the door frame can also prevent the door plate from folding independently compared to the door frame.

[0012] The hinged position of the side plate and the base is higher than the hinged position of the door frame and the back plate, because the door frame and the back plate are usually avoided when folding, and the height of the side plate is shorter, which is convenient for folding. Even if the side plate does not have a folding structure, the base still has enough length to match the folding of the side plate.

[0013] The door frame and the door plate in the scheme both have a folding structure, and the folding shaft lines of the two are coaxially arranged, so that the door frame and the door plate can be folded together, and the door frame and the door plate do not need to be removed when the storage cabinet is folded. Whether in transportation or assembly process, it can be convenient for the user to operate and save time. Moreover, the hinged position of the door frame and the base is lower than the hinged position of the side plate and the base, so that the door frame can be made larger, and the lower end of the door plate can be closer to the base. When the user opens the door plate, he can better get the items located below the storage cabinet.

[0014] As a preferred, the door plate includes an upper door plate and a lower door plate that can be folded with each other, the lower end of the lower door plate is hingedly connected with the lower end of the door frame, the upper end of the upper door plate is provided with the first fixing structure between the upper end of the door frame, and the second fixing structure for limiting the rotation of the lower door plate is arranged between the lower door plate and the door frame; when only the lower door plate and the door frame are fixed by the second fixing structure, the upper door plate can be opened alone.

[0015] The design incorporates a second fixing structure that allows the lower door panel to be individually fixed. Since the upper and lower door panels are hinged, the upper door panel can rotate independently when not fixed, enabling it to open and close independently. This increases the door panel's freedom of movement and expands its usability. Furthermore, because the storage cabinet is quite tall, the door panels also need to be tall. However, a taller door panel reduces stability. This design strengthens the lower door panel's stability by placing the second fixing structure at the lower door panel, resulting in better overall stability and preventing the door panels from folding over during use.

[0016] Preferably, the first fixing structure is located between the upper end of the upper door panel and the door frame, and the second fixing structure is located between the side end of the lower door panel and the door frame. Both the first fixing structure and the second fixing structure include several sliding grooves, sliding members, and insertion holes. The sliding grooves are provided on the upper door panel and the lower door panel, the sliding members are slidably fitted into the sliding grooves, and the insertion holes are provided on the door frame. The insertion holes correspond one-to-one with the sliding grooves and allow the sliding members to be inserted.

[0017] The upper and lower door panels are fixed to the door frame by inserting the sliding parts into the groove. This fixing method is faster and simpler.

[0018] Preferably, the slider has contraction portions extending along its length on both sides. One end of the contraction portion is fixed to the slider, while the other end is not fixed to the slider and there is a gap between the contraction portion and the slider. The outer side of the contraction portion has a laterally extending protrusion, and the groove wall of the slide groove has a protruding abutment portion. When the slider is inserted into or pulled out of the insertion hole, the abutment portion will abut against the protrusion, and the contraction portion will elastically contract so that the protrusion can pass over the abutment portion.

[0019] By providing a protrusion on the slider and the abutment of the protrusion, the movement of the slider is restricted, making it difficult to pull out the slider after it is inserted into the socket, or difficult to insert the slider when it is not inserted into the socket.

[0020] Preferably, the side panel is provided with a plurality of inserts extending toward the door frame and back panel, and the sides of the door frame and back panel are provided with slots for inserting into the inserts. When the inserts and slots are inserted, the door frame and back panel cannot fold on their own.

[0021] The insertion of blocks and slots restricts the folding of the door frame and back panel, ensuring the stability of the storage cabinet.

[0022] Preferably, the insert block is also provided with a buckle, and the slot wall is provided with a buckle groove for engaging with the buckle.

[0023] The insert block is secured after being inserted into the slot by setting a latch and a latch slot.

[0024] Preferably, the two side plates are a first side plate and a second side plate, with the hinge position of the first side plate to the base being higher than the hinge position of the second side plate to the base; at least the outer wall of the second side plate is provided with a clearance groove for avoiding the insertion block.

[0025] The first and second side panels are stacked vertically when folded. When folding, the first side panel is placed on the second side panel. Since the first and second side panels have inserts, a clearance groove is provided on the second side panel to avoid the inserts, which can ensure that the first side panel is horizontal when folded.

[0026] Preferably, the clearance groove is formed by an inward recess in the wall of the side plate.

[0027] Because the side plate is relatively thin, the clearance groove is formed by the wall recessing inward.

[0028] Preferably, the upper end of the side plate is provided with a hook that can slide in the front-back direction, and the lower end of the top plate is provided with a hook groove that cooperates with the hook; a connector is provided between the upper ends of the top plate and the back plate, the upper end of the connector is fixed to the top plate, the lower end of the connector is provided with a rotating shaft, and the back plate is provided with a rotating slot that can be detachably cooperated with the rotating shaft.

[0029] A combination cabinet with the above-mentioned folding storage cabinet includes a low cabinet located above the folding storage cabinet, and the lower end of the low cabinet is connected to the upper end of the folding storage cabinet by a stop joint; the difference between the low cabinet and the folding storage cabinet is that the door frame and door panel of the low cabinet do not have their own folding structure.

[0030] The combination cabinet is a combination of a storage cabinet and a low cabinet. Items can also be placed in the low cabinet. The structure of the low cabinet is roughly the same as that of the storage cabinet. The height of the low cabinet is smaller than that of the storage cabinet, so the height of the door frame of the low cabinet is shorter. The size of the base of the low cabinet is large enough to match the folded door frame, so the door frame and door panel do not need to have their own folding structure.

[0031] Compared with the prior art, this utility model has the advantage that the door frame does not need to be removed when the storage cabinet is folded, thus facilitating the transportation and assembly of the storage cabinet. Attached Figure Description

[0046] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0047] like Figures 1 to 5As shown, this embodiment discloses a combination cabinet with a folding storage cabinet. The combination cabinet 1 includes a folding storage cabinet 11 (hereinafter referred to as the storage cabinet) and a low cabinet 12 located on the storage cabinet 11. Both the low cabinet 12 and the storage cabinet 11 include a base 2, a first side panel 41, a second side panel 42, a door frame 3, a door panel 31, and a back panel 6. The first side panel 41 and the second side panel 42 are located on the left and right sides above the base 2, the door frame 3 is located on the front side above the base 2, and the back panel 6 is located on the rear side above the base 2. The low cabinet 12 also includes a top panel 5. Since the low cabinet 12 is located above the storage cabinet 11, the top panel 5 may not be provided on the top of the storage cabinet 11, and the base of the low cabinet 12 can be used for sealing. In some other embodiments, the storage cabinet 11 may also have a top panel 5, or when the storage cabinet 11 does not need to form the combination cabinet 1, the storage cabinet 11 is a separate cabinet, and the top of the storage cabinet 11 is equipped with a top panel 5. The base 2 of the storage cabinet 11 is also equipped with four wheels 13 at the bottom.

[0048] like Figures 1 to 5 As shown, the low cabinet 12 and the storage cabinet 11 have similar structures. The low cabinet 12 and the storage cabinet 11 have the same length and width, but their heights differ. The base 2 of the low cabinet 12 is fitted with the back panel 6, the first side panel 41 and the second side panel 42 of the storage cabinet 11 through a stop joint. The top of the back panel 6, the first side panel 41 and the second side panel 42 are provided with stepped surfaces (not shown in the figure), which abut against the bottom edge of the base 2 of the low cabinet 12.

[0049] A connector 51 is provided between the upper ends of the back panel 6 of the low cabinet 12. The upper end of the connector 51 is fixed to the top panel 5, and the lower end of the connector 51 is provided with a rotating shaft 511. The back panel 6 is provided with a rotating slot 61 that can be detachably engaged with the rotating shaft 511. After the top panel 5 is flipped upward, the rotating shaft 511 can be pulled out from the rotating slot 61 by pulling the top panel 5.

[0050] The upper ends of the first side plate 41 and the second side plate 42 are provided with hooks 43 that can slide in the front-back direction. The lower ends of the top plate 5 are provided with hook grooves (not shown in the figure) that cooperate with the hooks 43. When the hooks 43 slide and hook into the hook grooves, the top plate 5 is fixed together with the first side plate 41 and the second side plate 42 and cannot be flipped. When the hooks 43 slide out of the hook grooves, the top plate 5 separates from the first side plate 41 and the second side plate 42, so that the top plate 5 can be flipped.

[0051] Hinged walls 21 extend upwards around the base 2. The lower ends of the back panel 6, door frame 3, first side panel 41, and second side panel 42 are all hinged to the hinged walls 21 of the base. The hinge between the first side panel 41 and the base 2 is higher than the hinge between the second side panel 42 and the base 2. The hinge between the second side panel 42 and the base 2 is higher than the hinge between the door frame 3 and the base 2. The hinge between the door frame 3 and the base 2 is higher than the hinge between the back panel 6 and the base 2. A door panel 31 is provided on the door frame 3, and the lower end of the door panel 31 is hinged to the door frame 3.

[0052] The first side panel 41, the second side panel 42, and the back panel 6 of the storage cabinet 11 are also provided with the hooks 43 and rotating slots 61 that are present in the first side panel 41, the second side panel 42, and the back panel 6 of the low cabinet 12, so that the top panel 5 can also be configured at the top of the storage cabinet 11.

[0053] like Figures 8 to 10 As shown, both the first side panel 41 and the second side panel 42 are provided with several inserts 65 extending towards the door frame 3 and the back panel 6, and some inserts 65 are also provided with latches 64. The sides of the door frame 3 and the back panel 6 are provided with slots 62 for inserting into the inserts 65. When the inserts 65 and the slots 62 are inserted, the door frame 3 and the back panel 6 cannot fold themselves. Furthermore, some slots 62 are also provided with latching grooves 63 for engaging with the latches 64.

[0054] like Figures 5 to 7 As shown, the difference between the low cabinet 12 and the storage cabinet 11 is that the door frame 3 and door panel 31 of the low cabinet 12 do not have a self-folding structure, while the door frame 3 and door panel 31 of the storage cabinet 11 do have a self-folding structure. The door frame 3 of the storage cabinet 11 includes an upper door frame 32 and a lower door frame 33 of similar size, which are hinged together to allow the door frame 3 to fold itself. The door panel 31 includes an upper door panel 311 and a lower door panel 312 of similar size, which are hinged together to allow the door panel 31 to fold itself. The folding axis of the door panel 31 is coaxial with the folding axis of the door frame 3, allowing the door panel 31 and the door frame 3 to fold together.

[0055] Three first fixing structures 3111 are provided between the upper end of the upper door panel 311 and the upper end of the upper door frame 32, and two second fixing structures 3121 are provided between the left and right sides of the lower door panel 312 and the left and right inner sides of the lower door frame 33.

[0056] Both the first fixing structure 3111 and the second fixing structure 3121 include a sliding groove 7, a sliding member 71, and an insertion hole 34. The sliding groove 7 is provided on the upper door panel 311 and the lower door panel 312, and the sliding member 71 is slidably fitted in the sliding groove 7; the insertion hole 34 is provided on the upper door frame 32 and the lower door frame 33, and the insertion hole 34 corresponds one-to-one with the sliding groove 7 and allows the sliding member 71 to be inserted. The slider 71 has constriction portions 72 extending along its length on both sides. One end of the constriction portion 72 is fixed to the slider 71, while the other end is not fixed and there is a gap between the constriction portion 72 and the slider 71. A laterally extending protrusion 73 is provided on the outer side of the constriction portion 72, and an abutment portion 74 protrudes from the groove wall of the slide groove 7. When the slider 71 is inserted into or pulled out of the insertion hole 34, the abutment portion 74 abuts against the protrusion 73, and the constriction portion 72 elastically contracts so that the protrusion 73 can pass over the abutment portion 74. The slide groove 7 of the first fixing structure 3111 extends vertically, and the slide groove 7 of the second fixing structure 3121 extends horizontally. When the slider 71 slides into the socket 34, it will fix the door panel 31 and the door frame 3, and the door panel 31 is in the closed state. If the lower door panel 312 is fixed to the lower door frame 33, and the upper door panel 311 is not fixed to the upper door frame 32, the upper door panel 311 can be opened independently.

[0057] like Figure 10 and Figure 11 As shown, the outer walls at both ends of the first side plate 41 and the second side plate 42 are recessed inward to provide clearance grooves 44 for avoiding the insertion block 65. When the first side plate 41 and the second side plate 42 are folded, the insertion block 65 of the first side plate 41 will be placed in the clearance groove 44 to ensure that the first side plate 41 is horizontal.

[0058] like Figure 11 and Figure 13 As shown, when the combination cabinet 1 needs to be folded, first remove the top panel 5 from the low cabinet 12, and then remove the low cabinet 12 from the storage cabinet 11 to separate the two. Then, begin folding the low cabinet 12 and the storage cabinet 11. When folding the storage cabinet 11, first fold the back panel 6 and flip it onto the base 2. Then, fold the door frame 3 and the door panel 31 simultaneously and flip them onto the base 2, where they will overlap. Next, flip the second side panel 42 and the first side panel 41 in sequence, so that the first side panel 41 overlaps the second side panel 42. This completes the folding of the storage cabinet 11. The folding of the low cabinet 12 is roughly the same as that of the storage cabinet 11, except that the door frame 3 of the low cabinet 12 does not need to be folded; it can simply be flipped onto the base 2.
