Description

Technical Field

[0001] This utility model relates to the field of plastic frame technology, specifically providing a base for a folding basket and a folding basket. Background Technology

[0002] Plastic crates are common storage devices, used in factories to store spare parts or in markets to store vegetables. When not in use, plastic crates are bulky and inconvenient to store. Therefore, foldable plastic crates, also known as folding baskets, exist in the current technology. Folding baskets reduce their volume by folding, making them easier to store and transport. A folding basket typically consists of a base plate and four side plates, with the side plates hinged to the base plate. When folding is needed, the side plates fold inwards, eventually overlapping the base plate, reducing the height of the folding basket and thus its size. Folding baskets usually have a base plate and four side plates, arranged in pairs opposite each other. The base plate typically has hinge holes. Figure 6 As shown, the bottom of the side plate typically has a connecting part and a hinge shaft. The hinge shaft is connected to the side plate through the connecting part, and the connecting part creates a gap between the side plate and the hinge shaft, allowing the hinge shaft to connect with a hinge hole. The connecting part is usually a plate-like or block-like structure. The hinge between the side plate and the bottom plate allows the side plate to rotate relative to the bottom plate, enabling the side plate to rotate to a state where it overlaps with the bottom plate.

[0003] However, since the side panels in opposite positions are all made using the same mold, it's easier to control the cost of the folding basket. Therefore, the side panels in opposite positions have the same dimensions, and the hinge height is also the same after the side panels are connected to the bottom plate. When the side panels in opposite positions rotate to overlap with the bottom plate, one side panel will always flip onto the top of the other. At this point, the bottom of the upper side panel rests against the other side panel, preventing it from rotating to a horizontal position. This makes it difficult to stack the folding basket after it's been folded. Utility Model Content

[0004] This utility model provides a base and a folding basket for use in solving the problem that the side panels of existing folding baskets cannot all be rotated to a horizontal state after folding, making it inconvenient to stack the folding baskets.

[0005] The technical solution of this utility model is as follows:

[0006] A base for a folding basket includes a mounting portion for connection to a side panel and a bottom plate. The mounting portion includes a hinge cavity and a sliding opening. The hinge cavity is arranged vertically to accommodate a hinge shaft and allows the hinge shaft to move up and down. The sliding opening is located on the side of the hinge cavity and extends through the side. The sliding opening allows the connecting portion at the bottom of the side panel to move up and down.

[0007] In this design, when the side panels of the folding basket are connected to the base, the hinge shaft and other structures of the side panels are connected to the mounting part on the base. The mounting part includes a hinge cavity, within which the hinge shaft can move up and down. For example, a rectangular tube structure can be provided on the upper side of the base plate. The inner hole of the rectangular tube serves as the hinge cavity, while the opening on the side of the rectangular tube serves as a sliding opening. The top of the rectangular tube is closed to prevent the hinge shaft and other structures from detaching from the top. The part between the side panel and the hinge shaft and other structures is the connecting part. When the hinge shaft is lower in the hinge cavity, the connecting part is located at a lower position within the sliding opening; conversely, when the hinge shaft is higher in the hinge cavity, the connecting part is located at a higher position within the sliding opening. Therefore, because the hinge shaft can move up and down within the hinge cavity, it can be at different heights after the side panels are folded towards the base. These different hinge shaft heights allow both opposing side panels to rotate to a horizontal position, ensuring that the top of the folding basket remains horizontal after folding, thus enabling the folding basket to be stacked stably after folding. Furthermore, the large contact area between the side panels in the horizontal state allows the force to be distributed to various locations when subjected to stress, thereby improving the load-bearing capacity of the folding basket in the folded state and preventing the side panels from bending and being damaged due to excessive load.

[0008] To address the issue of the hinge shaft and other structures of the side plate sliding upwards out of the hinge cavity, a positioning element is provided in the hinge cavity, which is located at the top of the side of the hinge cavity.

[0009] In this solution, the positioning element can prevent the hinge shaft and other structures from moving upward, thereby preventing the hinge shaft from detaching from the hinge cavity from the top.

[0010] To address the inconvenience of installing the hinge shaft, the sliding opening includes a first opening and a second opening. The first opening communicates with the second opening, the width of the first opening is greater than the width of the second opening, and the first opening is located above the second opening.

[0011] In this design, the hinge shaft can enter the hinge cavity through the first opening, while the width of the second opening is smaller than that of the first opening, which can prevent the hinge shaft from leaving the hinge cavity through the second opening.

[0012] Preferably, the mounting plate includes at least two mounting portions.

[0013] In this design, at least two mounting points are provided, which increases the connection points between the base and the side plate and improves the stability of the connection.

[0014] Preferably, the mounting plate has a positioning groove on its top.

[0015] In this design, the positioning groove can be used in conjunction with the side plate. If the side plate is fitted with a positioning boss that fits the positioning groove, and the positioning boss is engaged in the positioning groove, the engagement between the positioning boss and the positioning groove can prevent the side plate from moving in the left and right directions along the plate surface.

[0016] To address the issue of unbalanced forces exerted on the hinge shaft by the positioning elements, the hinge cavity is provided with two positioning elements, which are respectively located on two opposite sides of the hinge cavity.

[0017] In this design, positioning elements are provided on two opposite sides of the hinge cavity. The two positioning elements can act on both sides of the hinge shaft respectively, so that the hinge shaft is subjected to balanced force and the stability of the connection between the side plate and the base is improved.

[0018] To address the issue of two positioning elements obstructing the installation of the hinge shaft, a gap is placed between the two positioning elements.

[0019] In this design, the spacing between the two positioning members allows the connecting part of the side plate to pass between the two positioning members, enabling the connecting part of the side plate to smoothly enter the mounting part.

[0020] Preferably, the hinge cavity extends vertically through the mounting plate.

[0021] In this design, the hinge cavity extends through the mounting plate from top to bottom, facilitating machining and forming.

[0022] Preferably, the base includes at least two mounting plates, which are disposed on opposite sides of the base plate.

[0023] In this design, the base is provided with at least two opposing mounting plates, each with a mounting part. The side plates connected to the two mounting plates can be folded to different heights, thus allowing the side plates to be folded to a horizontal state and improving load-bearing capacity.

[0024] This utility model also provides a folding basket, including the aforementioned base.

[0025] The beneficial effects of this utility model are:

[0026] The base of this invention is provided with a mounting part including a hinge cavity and a sliding opening. The side panels can connect to the hinge cavity, and the portion of the side panel connected to the hinge cavity can move up and down within the hinge cavity. Therefore, when the side panels are folded, the portion of the side panel connected to the mounting part can be at different heights, allowing the side panels to rotate to a horizontal position, facilitating the stacking of the folded frames. The mounting part of the base allows both side panels to be folded to a horizontal position, thus improving the load-bearing capacity of the assembled folding basket. Attached Figure Description

[0036] The technical solution of this utility model will be clearly and completely described in conjunction with the accompanying drawings and through specific embodiments.

[0037] Example 1:

[0038] like Figure 1 and Figure 2 As shown, this embodiment provides a base for a folding basket. The base includes a base plate 1 and a mounting plate 2 for mounting side panels. The mounting plate 2 is connected to the side of the base plate 1. A mounting portion 4 for connecting to the side panels is provided on the mounting plate 2. The mounting portion 4 includes a vertically arranged hinge cavity 43 and a sliding opening on the side of the hinge cavity 43. The sliding opening penetrates the side wall of the hinge cavity 43, connecting the hinge cavity 43 to the external environment.

[0039] The side plate is usually connected to the hinge cavity 43 via a hinge shaft. The top of the hinge cavity 43 passes through the mounting part 4. The hinge shaft can enter the hinge cavity 43 from the top of the hinge cavity 43 and can move up and down within the hinge cavity 43, so that the hinge shaft can be at different heights.

[0040] A positioning element 44 is provided at the top of the hinge cavity 43. The positioning element 44 is located inside the hinge cavity 43. If the hinge axis of the side plate is located inside the hinge cavity 43 and moves upward, in order to prevent the hinge axis from disengaging from the top of the hinge cavity 43, a positioning block can be inserted between the hinge axis and the positioning element 44. The positioning block will abut against the bottom of the positioning element 44, thereby preventing the hinge axis from continuously moving upward and disengaging from the hinge cavity 43. When the side plate is in a vertical state, the bottom surface of the side plate abuts against the top surface of the mounting plate 2, and the positioning block abuts against the positioning element 44. When the side plate is subjected to an upward force, the force will be transmitted to the positioning element 44 through the positioning block, and the positioning element 44 will transmit the force to the entire base.

[0041] The positioning block can be fixed to the connecting part. The positioning block can also be a separate block structure or a rod structure.

[0042] like Figure 2 and Figure 5 As shown, two symmetrically arranged positioning members 44 are provided in the hinge cavity 43. The symmetrically arranged positioning members 44 can make the force on both sides of the hinge cavity 43 uniform and improve the stability of the positioning members 44.

[0043] Since the positioning element 44 can bear the force from the positioning block, the hinge cavity 43 can be directly inserted through the mounting plate 2 from the top and bottom to facilitate processing. There is no need to design the vertical depth of the hinge cavity 43 separately, which reduces the processing difficulty.

[0044] like Figure 3 As shown, the positioning element 44 can be in the shape of a cuboid or a cylinder, and the positioning element 44 is located on one side near the middle of the base plate 1.

[0045] The sliding opening is also located on one side near the middle of the base plate 1. When the hinge shaft is subjected to a force toward the middle of the base plate 1, the positioning member 44 is located diagonally above the hinge shaft. The positioning member 44 will give the hinge shaft a reaction force toward the outside of the base plate 1, preventing the hinge shaft from sliding toward the middle of the base plate 1.

[0046] When the width of the positioning block is greater than the width of the connecting part, the sliding opening includes a first opening 41 and a second opening 42, wherein the first opening 41 and the second opening 42 are interconnected, and the first opening 41 is located above the second opening 42. The function of the first opening 41 is to allow the positioning block to be engaged, and the hinge shaft needs to be inserted into the hinge cavity 43 through the first opening 41. The width of the second opening 42 is greater than the width of the connecting part, allowing the connecting part to move up and down along the second opening 42. The width of the second opening 42 is less than the length of the hinge shaft, preventing the hinge shaft from leaving the hinge cavity 43 through the second opening 42, thus preventing the side plate from detaching from the mounting plate 2.

[0047] The height of the positioning member 44 corresponds to the top position of the first opening 41, which can provide a downward reaction force to the hinge shaft. There is a gap between the two positioning members 44. The width of the gap is greater than the width of the connecting part and less than the length of the hinge shaft, so that the connecting part can pass between the two positioning members 44, allowing the side plate to rotate to a vertical position, and preventing the positioning members 44 from blocking the connecting part and causing the side plate to be unable to rotate to a vertical position.

[0048] The base plate 1 is rectangular or square in shape. It can have a mounting plate 2 on one side and fixed hinge holes on the other three sides. Only one side plate needs to be adjustable in height after rotation, allowing it to rise or fall when horizontal, thus placing it at different heights from the opposite side plate and making them parallel. For example, if one side plate is 5mm thick, the side plate connected to the fixed hinge hole maintains its height after rotation, while the side plate connected to the mounting part 4 moves 5mm up or down after rotation, allowing it to rotate to a horizontal position and overlap the other side plate.

[0049] Similarly, two, three, or four mounting plates 2 can also be installed on the base plate 1.

[0050] In a preferred embodiment, two mounting plates 2 are provided on the base plate 1, positioned opposite each other and located along the long edge of the base plate 1. The longer side plates are mounted along the long edge of the base plate 1, while the shorter side plates are mounted along the short edge. Since the side plates are typically of the same height, when folding towards the center, the two shorter side plates do not need to overlap, while the two longer side plates usually need to overlap; hence, mounting plates 2 are provided along the long edge of the base plate 1. Using two mounting plates 2 avoids the problem of side plates failing to rotate to a horizontal position due to assembly errors or other reasons.

[0051] A positioning groove 3 can be provided on the top of the mounting plate 2. The positioning groove 3 is used to cooperate with the side plate. A positioning boss is provided at the corresponding position on the bottom of the side plate, and the positioning boss is engaged in the positioning groove 3. When the side plate is subjected to a force along the axis of the hinge shaft, the cooperation between the positioning boss and the positioning groove 3 can prevent the side plate from moving. At this time, the hinge shaft will not bear axial force and will not be damaged.

[0052] In one embodiment, a rectangular tube structure is provided on the upper side of the base plate. The inner hole of the rectangular tube serves as the hinge cavity 43, while the opening on the side of the rectangular tube serves as a sliding opening. The top of the rectangular tube is closed to prevent the hinge shaft and other structures from detaching from the top. This embodiment does not require a mounting plate; the mounting part forms a separate protruding structure on the top of the base plate. In this case, a corresponding protruding plate needs to be provided at the bottom of the side plate to fill the gap between the rectangular tubes.

[0053] Example 2:

[0054] This second embodiment provides a folding basket, which includes the base described in the first embodiment and also includes a side panel.

[0055] At least one mounting plate 2 is provided on the base.

[0056] The side plate has a connecting part at its bottom, and a hinge shaft is provided at the bottom end of the connecting part. The side plate is connected to the mounting plate 2 on the base via the hinge shaft.

[0057] During folding, the side panels connected to mounting plate 2 can change their height in the horizontal state, thus keeping them level. In other words, when folding the side panels, regardless of which side panel folds towards the base first, both opposing side panels can rotate to a horizontal position, ensuring the top of the folded crate remains horizontal, facilitating rapid stacking of multiple crates. When all side panels are horizontal, the force on the side panels can be evenly transmitted downwards to the base plate 1. This even force distribution improves the load-bearing capacity of the side panels, thereby increasing the overall load-bearing capacity of the folded crate in the folded state.

[0058] When the side panels are folded, whichever side panel folds towards the base first will allow the two opposing side panels to rotate to a horizontal position, keeping the top of the turnover basket horizontal after folding, which facilitates the rapid stacking and palletizing of multiple turnover baskets.

[0059] like Figure 6 As shown, load-bearing parts 8 are also provided on both sides of the connecting part 6 at the bottom of the side plate 5. The load-bearing parts 8 are located between the hinge shaft 7 and the body of the side plate 5. When the side plate 5 is rotated to the vertical position, the top of the load-bearing part 8 can be locked under the positioning part 44. At this time, the side plate 5 can only rotate and cannot move up and down. When the side plate 5 is lifted upward, the base and the side plate 5 will not move relative to each other.
