Abstract
Description
Technical Field
[0001] This utility model relates to the field of storage technology, and more specifically, to a stackable storage box. Background Technology
[0002] Traditional storage boxes are mostly made of one-piece molded plastic, and for ease of demolding during manufacturing, they are typically trapezoidal in shape, wider at the top and narrower at the bottom, with rigid handles on opposite sides. When not in use, several boxes can be stacked to create a compact volume for easy storage. However, when items are inside and stacking is attempted to save space, the lack of a stable support structure between the bottom of one box and the top of another often results in instability, with the boxes easily jamming together under gravity, making them difficult to move. Another existing storage box method uses covers on the box body for stacking, but this is inconvenient and wastes too much material. Utility Model Content
[0003] To address at least one of the aforementioned problems, this utility model first provides a stackable storage box, comprising a box body and handles rotatably connected to both sides of the box body. Each handle has a mounting portion, and both sides of the box body have mounting openings. The mounting portion and the mounting openings are detachably connected, and the mounting portion has a supporting surface. When the handle is rotated to a folded state, the mounting portion connects to the mounting opening, and the supporting surface is located at the upper end of the mounting portion and is parallel or nearly parallel to the bottom surface of the box body, allowing another box body to be stacked on the supporting surface.
[0004] Optionally, the lower edge or side edge of the mounting portion is provided with a first buckle, which is adapted to engage with the inner sidewall edge of the mounting opening.
[0005] Optionally, the first buckle is provided with a guide slope, and the guide slope is slidably connected to the side wall of the mounting port so as to facilitate an interference fit between the mounting part and the mounting port.
[0006] Optionally, the mounting part is provided with a limiting part, and the bottom of the box is provided with a support leg. When the handle is in a folded state and another box is stacked, the support leg of the upper box is limited between the limiting parts on both sides of the lower box.
[0007] Optionally, the rotation angle between the outer wall of the handle and the upper surface of the box body is in the range of 0-95 degrees.
[0008] Optionally, the mounting part is provided with an opening for inserting a finger to move the box body through the handle.
[0009] Optionally, the upper end of the handle is provided with a second buckle, the vertical cross-section of the second buckle being an inverted L-shape; when the handle is rotated to the unfolded state, the second buckle engages with the upper end of the side wall of the box body to provide support force when pulling the handle, preventing the rotation axis of the handle from being subjected to excessive force and breaking.
[0010] Optionally, the handle is provided with a support wall; when the handle is in the folded state, the support wall and the outer wall of the box are spaced apart so that fingers can be inserted into the gap to open the handle; when both handles are in the unfolded state, the support walls on both sides cooperate to support the external water tank so that the box can be accommodated in the water tank for use.
[0011] Optionally, the box body is a trapezoidal shape that is wider at the top and narrower at the bottom, and a support column is provided on the inner wall of the box body; when the handle is folded out, another box body can be stacked on the support column.
[0012] Optionally, the upper end of the outer wall of the box is inclined outward to form a clearance portion. When another box is stacked on the support column, a clearance cavity is formed between the outer wall of the other box and the clearance portion. The clearance cavity is used to avoid the second buckle so that the handle below can be rotated to the unfolded state.
[0013] Compared to existing technologies, the stackable storage box of this utility model features a rotatable handle that allows for detachable connection between the mounting part on the handle and the mounting port on the box body. This enables the support surface of the handle to support the stacking of another box when the handle is folded, preventing the upper box from pressing down on the items inside the lower box. The stacking is also more stable, easier to access, simple in structure, convenient to operate, and low in cost. It allows multiple boxes to be stacked sequentially, thereby reducing the space occupied. Attached Figure Description

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0027] The accompanying drawings of the embodiments of this utility model provide a coordinate system XYZ, where the positive direction of the X-axis represents the left and the negative direction of the X-axis represents the right, the positive direction of the Y-axis represents the front and the negative direction of the Y-axis represents the back, the positive direction of the Z-axis represents the top and the negative direction of the Z-axis represents the bottom.
[0028] This utility model embodiment provides a stackable storage box, combined with Figures 1 to 10 As shown, the device includes a box body 1 and handles 2 rotatably connected to both sides of the box body 1. The handles 2 are provided with mounting parts 21, and the box body 1 is provided with mounting openings 11 on both sides. The mounting parts 21 and the mounting openings 11 are detachably connected. The mounting parts 21 are provided with support surfaces 211. When the handles 2 are rotated to the folded state, the mounting parts 21 are connected to the mounting openings 11. The support surfaces 211 are located at the upper end of the mounting parts 21 and are parallel or nearly parallel to the bottom surface of the box body 1, so that another box body 1 can be stacked on the support surfaces 211.
[0029] like Figures 1 to 3As shown, the projections of the support surface 211 and the bottom of the box 1 on the horizontal plane intersect. The stackable storage box of this utility model, by setting a rotatable handle 2, allows the mounting part 21 on the handle 2 and the mounting port 11 on the box 1 to be detachably engaged, so that when the handle 2 is in the folded state, the support surface 211 can support another box 1 to be stacked. The upper box 1 will not press on the items in the lower box 1, and the stacking is more stable, easy to pick up and put away, with a simple structure, convenient operation, low cost, and multiple boxes 1 can be stacked in sequence to reduce the space occupied.
[0030] Optionally, the lower edge or side edge of the mounting portion 21 is provided with a first buckle 212, which is adapted to engage with the inner side wall edge of the mounting opening 11.
[0031] like Figure 3 As shown, in this embodiment, the first latch 212 is located at the lower edge of the mounting portion 21. When the handle 2 is in a folded state and another box 1 is stacked, the upper box 1 transmits downward pressure to the mounting portion 21. Then, under the action of the rotation axis of the handle 2, the downward pressure is converted into downward and outward forces. The first latch 212 cooperates with the inner wall of the mounting opening 11 to stabilize the support structure. The inner edge of the mounting opening 11 is slightly raised to cooperate with the first latch 212, making the latching structure more stable.
[0032] like Figure 3 and 6 As shown, optionally, the first buckle 212 is provided with a guide slope 213, which is inclined outward from top to bottom. The guide slope 213 is slidably connected to the side wall of the mounting port 11 so as to facilitate the interference fit between the mounting part 21 and the mounting port 11.
[0033] Optionally, the mounting part 21 is provided with a limiting part 214, and the bottom of the box body 1 is provided with a support leg 12. When the handle 2 is in a folded state and another box body 1 is stacked, the support leg 12 of the upper box body 1 is limited between the limiting parts 214 on both sides of the lower box body 1.
[0034] like Figure 3 As shown, in this embodiment, the limiting part 214 is perpendicular or nearly perpendicular to the bottom of the box body 1. The limiting part 214 is adapted to limit the contact with the side wall of the support leg 12. The limiting parts 214 on both sides of the handle 2 cooperate to restrict the position of the stacked box body 1, prevent the box body 1 from swaying left and right, and make the stacking effect more stable. When the box body 1 is used alone, the support leg 12 can be supported on the ground, which can play a role in preventing dust and moisture at the bottom of the box body 1.
[0035] like Figure 3 and 10As shown, optionally, the rotation angle range between the outer wall of the handle 2 and the upper surface of the box 1 is 0-95 degrees. Specifically, the two rotation limit positions of the handle 2 are the positions in the unfolded state and the folded state; when the handle 2 is rotated upward to the unfolded state, the outer wall of the handle 2 is parallel or nearly parallel to the horizontal plane; when the handle 2 is rotated downward to the folded state, the outer wall of the handle 2 is parallel to the vertical plane, or the outer wall of the handle 2 is inclined towards the side wall of the box 1, with an inclination angle of less than or equal to 5 degrees.
[0036] like Figure 3 and 7 As shown, optionally, the mounting part 21 is provided with an opening 215, which is used to insert a finger and move the box body 1 through the handle 2. The two handles 2 are respectively hinged to the left and right sides of the box body 1. Both the mounting port 11 and the opening 215 are oblong. The user can grasp the handle 2 through the opening 215 and rotate the handle 2 to change the usage state; or by grasping the handle 2, push / pull / lift the box body 1.
[0037] like Figure 10 As shown, optionally, the upper end of the handle 2 is provided with a second buckle 22, the vertical cross-section of which is an inverted L-shape. When the handle 2 is rotated to the unfolded state, the second buckle 22 engages with the upper end of the side wall of the box body 1 to provide support when pulling the handle 2, preventing the rotation axis of the handle 2 from being subjected to excessive force and breaking when the user pushes / pulls / lifts the box body 1 with the handle 1 in the unfolded state. At the same time, the upper end wall of the second buckle 22 restricts the rotation angle of the handle 2, so that the handle 2 is nearly parallel to the horizontal plane when in the unfolded state.
[0038] Optionally, the handle 2 is provided with a support wall 23; when the handle 2 is in the folded state, the support wall 23 and the outer wall of the box 1 are spaced apart so that the fingers can be inserted into the gap to open the handle 2; when both handles 2 are in the unfolded state, the support walls 23 on both sides cooperate to support the external water tank so that the box 1 can be accommodated in the water tank for use.
[0039] like Figure 8 As shown in the figure, the support wall 23 is longer, making it easier to support on the sink. Furthermore, when the stacked storage box is used in the kitchen, several drainage holes can be opened at the bottom of the box body 1 for washing vegetables or placing dishwashing tools, etc.
[0040] like Figure 6 As shown, optionally, the box body 1 is a trapezoidal body that is wider at the top and narrower at the bottom, and the inner wall of the box body 1 is provided with a support column 13; when the handle 2 is unfolded, another box body 1 can be stacked on the support column 13.
[0041] In this embodiment, there are four support columns 13 distributed at the four corners of the box 1, which provides support when stacked without affecting the storage effect. Furthermore, the cross-section of the support column 13 is semi-circular, which reduces the space occupied while maintaining the support effect.
[0042] like Figure 6 and 10 As shown, optionally, the upper end of the outer wall of the box 1 is inclined outward to form a clearance portion 14. When another box 1 is stacked on the support column 13, a clearance cavity 141 is formed between the outer wall of the other box 1 and the clearance portion 14. The clearance cavity 141 is used to avoid the second buckle 22, so that the handle 2 at the bottom can be rotated to the unfolded state. The user can unfold the bottom handle 2 and lift the stacked box 1 together by lifting the handle 2.
[0043] Working principle: The stackable storage box of this utility model has two stacking usage methods. The first method is to rotate the handles 2 on both sides of the box body 1 to the folded state, so that the first buckle 212 is engaged with the inner side wall of the mounting port 22. At this time, another box body 1 can be stacked on the support surface 211. Because the handles 2 are rotated and connected to the upper end of the side wall of the box body 1, the two stacked box bodies 1 are spaced far apart in the vertical direction, providing a large storage space, which is convenient for storing items. Moreover, stacking multiple box bodies 1 reduces the space occupied.
[0044] The second method involves unfolding the handles 2 on both sides of the box 1. Specifically, this can be done in an unfolded state or somewhere between a folded and unfolded state. Because the shape of the box 1 is a trapezoid that is wider at the top and narrower at the bottom, a stacking effect can be achieved using the support pillars 13. The upper box 1 will be partially inserted into the lower box 1, reducing the space occupied in the vertical direction, facilitating transportation and storage of the box 1. The support pillars 13 not only stabilize the stacking effect but also make it easy to remove the box 1 after stacking, preventing it from getting stuck.
[0045] Furthermore, regardless of whether it is the first or the second stacking state, the handle can be used to move the box.
[0046] The above embodiments are merely illustrative of several implementation methods of this disclosure, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept of this disclosure, and these modifications and improvements all fall within the protection scope of this disclosure.
