Description

Technical Field

[0001] This invention relates to the field of turnover box technology, and specifically to a box. Background Art

[0002] The use of side panel frames in the packaging of auto parts is very common. Since most auto parts have their own standardized packaging, side panel frames primarily serve to protect against rain and dust. These frames are mainly made by bending hollow boards, with side panel thicknesses mostly less than 12mm, resulting in limited load-bearing capacity. The biggest drawback of this type of side panel frame is that, because it is made from a single bent hollow board, any unacceptable damage in one area necessitates the discarding of the entire frame.

[0003] There is currently a foldable collapsible box on the market. Its side panels are made using a blow molding process, with each side panel being a separate part. The box body is formed by connecting and assembling the side panels and then mounting them onto a base. While the standard collapsible box dimensions can be no less than 800mm*600mm*500mm, the blow-molded collapsible box can have side panel thicknesses exceeding 25mm, offering strength far superior to 12mm thick hollow boards. This makes it a better solution for medium-load-bearing requirements (edge ​​sealing becomes difficult with hollow boards exceeding 12mm thickness). The side panels of this collapsible box consist of two pairs of opposing side panels. Each longer side panel is a single, integral structure, while each shorter side panel comprises two roughly symmetrical sidewalls, connected by a hinge structure. The short and long side panels are connected by a structural pivot, allowing each sidewall of the shorter side panel to fold inward relative to the longer side panel, thus achieving a folded-down state and saving storage space when not in use.

[0004] The pivot connecting the long and short side panels of the aforementioned enclosure box is a long cylinder or tube that passes through the shaft holes on the long and short side panels sequentially from top to bottom. This structural design is relatively simple to manufacture and is also used in some injection-molded enclosure frames. However, its drawbacks are also quite obvious: firstly, the pivot is not easy to assemble and disassemble; secondly, the large clearance between the shaft hole and the pivot can lead to hygiene problems, such as rainwater or wastewater entering the interior of the side panels during cleaning. Therefore, a new side panel connection method is needed to solve this problem. Summary of the Invention

[0005] The purpose of this invention is to provide a housing in which adjacent side panels are provided with shafts and shaft holes, which not only facilitates the connection of each side panel, but also facilitates the cleaning of each side panel.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A housing includes a base and a plurality of side panels, wherein the plurality of side panels and the base enclose a rectangular cavity, and the plurality of side panels include a pair of first side panels and a pair of second side panels disposed opposite to each other.

[0008] The end of the first side plate connected to the second side plate is provided with a plurality of protrusions. The plurality of protrusions are spaced apart at the end of the first side plate along the depth direction of the cavity, and the protrusions protrude in a direction perpendicular to the inner wall of the first side plate; the protrusions have holes opened along the depth direction of the cavity.

[0009] The second side plate is provided with a plurality of grooves at the end where it connects to the first side plate, and the plurality of grooves are spaced apart along the depth direction of the cavity at the end of the second side plate; a shaft extending along the depth direction of the cavity is provided in the groove;

[0010] When the first side plate is connected to the second side plate and forms a rectangle with the base, the protruding part is located in the groove and the shaft is located in the hole.

[0011] In one embodiment, the first side plate is further provided with a limiting portion, which extends from one side of the lower end face of the protrusion along the depth direction of the cavity; the second side plate is further provided with a notch, which extends from the outer side of the bottom surface of the groove along the depth direction of the cavity, and when the first side plate and the second side plate are connected and enclosed with the base to form the rectangle, at least a portion of the limiting portion is located in the groove.

[0012] In one embodiment, the length of the notch extending along the depth direction of the cavity is not less than the length of the shaft.

[0013] In one embodiment, the limiting portion and the notch are further configured such that when the angle between the first side plate and the second side plate is not greater than a first preset angle, at least a portion of the limiting portion is located in the groove and abuts against the bottom surface of the groove; when the angle between the first side plate and the second side plate is greater than a second preset angle, the limiting portion is located in the notch.

[0014] In one embodiment, the first preset angle is 85-95 degrees, and the second preset angle is 100-130 degrees.

[0015] In one embodiment, the first preset angle is 90 degrees, and the second preset angle is 105-125 degrees.

[0016] In one embodiment, the limiting portion is a sheet extending along the depth direction of the cavity, and the notch is a wedge-shaped notch that gradually narrows from the end of the second side plate toward the end away from the second side plate.

[0017] In one embodiment, the protrusion is provided with a recessed portion on the opposite side of the limiting portion, the recessed portion being recessed in the direction of the limiting portion, and the depth of the recessed portion gradually decreases from the end near the first side plate to the end away from the first side plate.

[0018] In one embodiment, the end face of the second side plate is provided with an inclined surface, the inclined surface is inclined from the outer wall of the second side plate towards the inner wall, and the distance between the inclined surface and the first side plate gradually decreases from the outer wall of the second side plate towards the inner wall.

[0019] In one embodiment, the first side panel includes two side panel units arranged side by side, and the two side panel units are pivotally connected to each other.

[0020] In one embodiment, the first side plate further includes a connector, the connector being provided with two pivot shafts, the two pivot shafts being pivotally connected to the two side plate units respectively.

[0021] The present invention, employing the above-described technical solution, has the following advantages: the housing provided by the present invention uses shafts and holes on adjacent side plates. At a first preset angle, the shaft is inserted into the shaft hole, allowing the side plates to remain connected. At a second preset angle, the shaft can disengage from the hole, allowing the side plates to be disassembled, facilitating assembly and disassembly of the side plates. Furthermore, the protrusion, limiting portion, groove, shaft, and notch on the first and second side plates can all be integrally formed during blow molding of the first and second side plates. The outer surfaces of each side plate are sealed, preventing external debris from entering the interior of each side plate. Moreover, the protrusion, limiting portion, groove, and notch are all open after disassembly, facilitating cleaning. Attached Figure Description

[0041] This embodiment provides a housing, such as Figure 1 and Figure 2 As shown, the housing includes a base 1 and multiple side panels, which together with the base 1 form a rectangular cavity 10. Each side panel is typically a blow-molded part. The multiple side panels include a pair of first side panels 2 and a pair of second side panels 3 arranged opposite each other. The base 1 is provided with multiple guard edges 11 extending along the depth direction of the cavity 10. Each guard edge 11 is provided corresponding to one of the side panels, and each guard edge is provided with a number of hanging slots 12. The bottom of each side panel is also provided with hooks 4 corresponding to the hanging slots 12. Each side panel cooperates with the corresponding hanging slots 12 through the hooks 4 on its bottom, which restricts the side panels from detaching from the base when the housing is unfolded and used, and also restricts the outward displacement or deformation of each side panel. In one embodiment, the hook 4 is provided with a pivot 41, and the hanging groove 12 is provided with a pivot groove 121 that matches the pivot 41. The pivot 41 of the hook 4 is located in the pivot groove 121 of the corresponding hanging groove 12, so that each side plate can be folded relative to the base 1. The folded side plate can be attached to the base 1 or removed separately.

[0042] In this embodiment, the first side panel 2 is a short side panel with a shorter length, and the second side panel 3 is a long side panel with a longer length. A door 30 can also be provided on the long side panel. The first side panel 2 consists of two side panel units 21 arranged side by side and a connector 22. The connector 22 includes two pivot shafts, which are pivotally connected to the two side panel units 21 respectively, allowing the two side panel units 21 to be folded in half. After the two first side panels 2 are folded in half, the two second side panels 3 can simultaneously move closer together, and the four side panels can achieve the following: Figure 3 The folded state shown indicates that the four side panels can be folded up and laid flat towards the base 1 for easy folding. See also Figure 1 and Figure 2 In this embodiment, the base 1 is a roughly rectangular structure, and the four side plates are also roughly rectangular. The four side plates and the base 1 together form a cuboid box. The dimensions of the box are typically approximately 800mm*600mm*500mm, but can be increased or decreased according to actual needs. The thickness of each side plate is typically not less than 25mm to ensure sufficient strength.

[0043] See Figure 4 The end of the first side plate 2 connected to the second side plate 3 is provided with a plurality of protrusions 23. The plurality of protrusions 23 are spaced apart along the depth direction of the cavity 10 at the end of the first side plate 2, and the protrusions 23 protrude in a direction perpendicular to the inner wall of the first side plate 2. The protrusions 23 have holes 231 opened in the depth direction of the cavity 10.

[0044] See Figure 5 The end of the second side plate 3 connected to the first side plate 2 is provided with a plurality of grooves 31, and the plurality of grooves 31 are spaced apart along the depth direction of the cavity 10 at the end of the second side plate 3; a shaft 32 extending along the depth direction of the cavity 10 is provided in the groove 31.

[0045] See Figure 6 and Figure 7 When the first side plate 2 is connected to the second side plate 3 and forms a rectangle with the base 1, the protrusion 23 is located in the corresponding groove 31 and the shaft 32 is located in the hole 231. By rotating the shaft 32 in the corresponding hole 231, the first side plate 2 can rotate relative to the second side plate 3 at a certain angle, thereby achieving the purpose of folding.

[0046] To facilitate the assembly and disassembly of the first side plate 2 and the second side plate 3, refer to Figures 4-7The first side plate 2 is also provided with a limiting part 24, which extends from one side of the lower end face of the protrusion 23 along the depth direction of the cavity 10. Correspondingly, the second side plate 3 is also provided with a notch 33, which extends from the outer side of the bottom surface of the groove 31 along the depth direction of the cavity 10. When the first side plate 2 and the second side plate 3 are connected and enclosed with the base 1 to form a rectangle, at least a portion of the limiting part 24 is located in the groove 31. The groove 31 restricts the vertical movement of the first side plate 2 relative to the second side plate 3, so that the shaft 32 is always located in the hole 231, so that the first side plate 2 and the second side plate 3 maintain a connected state, allowing each side plate to maintain a rectangular cavity during normal use of the housing.

[0047] When the side panels need to be folded, the notch 33 is set to extend along the depth direction of the cavity 10 for a length not less than the length of the shaft 32. This allows the limiting part 24 and the notch 33 to be further configured such that when the angle between the first side panel 2 and the second side panel 3 is not greater than the first preset angle, at least a portion of the limiting part 24 is located in the groove 31 and abuts against the bottom surface of the groove 31. The groove 31 restricts the up-and-down movement of the first side panel 2 relative to the second side panel 3, and the shaft 32 is always located in the hole 231, so that the first side panel 2 and the second side panel 3 maintain a state of mutual connection, allowing each side panel to maintain a rectangular cavity during normal use of the housing.

[0048] See Figures 8-11 When the included angle between the first side plate 2 and the second side plate 3 is greater than the second preset angle, the limiting part 23 is located in the notch 33, allowing the shaft 32 to be disengaged from the hole 231, thereby allowing the first side plate 2 and the second side plate 3 to be disconnected, and thus the first side plate 2 and the second side plate 3 can be separated.

[0049] Preferably, the first preset angle is 85-95 degrees, and the second preset angle is 100-130 degrees. More preferably, the first preset angle is 90 degrees, and the second preset angle is 105-125 degrees. That is, when the first side plate 2 and the second side plate 3 are approximately perpendicular, each side plate can maintain a rectangular cavity. When the first side plate 2 is flipped outward relative to the second side plate 3 by an angle, the first side plate 2 and the second side plate 3 can be disconnected, allowing them to be separated, thus facilitating the folding of each side plate. Correspondingly, when assembling the first side plate 2 and the second side plate 3, firstly, the limiting parts 23 are all located within the notch 33, then the plate is lifted upward and rotated by a certain angle so that at least a portion of the limiting parts 24 is located within the groove 31 and abuts against the bottom surface of the groove 31, so that the shaft 32 can be inserted into the hole 231, thus maintaining the interconnected state of the first side plate 2 and the second side plate 3. Therefore, the assembly connection between the first side plate 2 and the second side plate 3 not only facilitates the folding of each side plate, but also facilitates the assembly connection between each side plate. In addition, the protrusion 23 and the limiting part 24 of the first side plate 2, the groove 31, the shaft 32 and the notch 33 on the second side plate 3 can be integrally formed with the first side plate 2 and the second side plate 3 during the blow molding process, and the outer surface of each side plate is in a sealed state, so that external debris will not enter the interior of each side plate. Furthermore, the protrusion 23, the limiting part 24, the groove 31 and the notch 33 are all in an open state after disassembly, which facilitates cleaning.

[0050] See Figure 3 The limiting part 24 is a sheet extending along the depth direction of the cavity 10. The notch 33 is a wedge-shaped notch that gradually narrows from the end of the second side plate 3 toward the end away from the second side plate 3. The assembly connection between the first side plate 2 and the second side plate 3 and the rotational folding can be achieved by the cooperation between the sheet and the wedge-shaped notch.

[0051] See Figure 10 and Figure 11 The protruding portion 23 has a recess 232 on the opposite side of the limiting portion 24, which is recessed towards the limiting portion. The depth of the recess 232 gradually decreases from the end near the first side plate 2 to the end away from the first side plate 2. That is, a recess 232 is formed on the outer side of the end where the protruding portion 23 connects to the first side plate 2. Figure 10 , Figure 11 The recess 232 shown can prevent interference when the first side plate 2 is flipped outward relative to the second side plate 3.

[0052] See Figure 10 and Figure 11The end face of the second side plate 3 is provided with an inclined surface 34. The inclined surface 34 is inclined from the outer wall of the second side plate 3 to the inner wall, and the distance between the inclined surface 34 and the first side plate 2 gradually decreases from the outer wall of the second side plate 3 to the inner wall. The inclined surface 34 can also avoid interference when the first side plate 2 flips outward relative to the second side plate 3.

[0053] The preferred embodiments of the present invention have been described in detail above. However, it should be understood that after reading the above teachings, those skilled in the art can make various alterations or modifications to the present invention. These equivalent forms also fall within the scope defined by the appended claims.
