Description

Technical Field

[0001] This utility model relates to the field of logistics equipment technology, and more specifically, to a foldable logistics turnover box. Background Technology

[0002] Logistics turnover boxes, also known simply as logistics boxes or turnover boxes, are widely used in industries such as machinery, automobiles, home appliances, light industry, and electronics. They are acid and alkali resistant, oil resistant, non-toxic, and odorless, suitable for storing food, easy to clean, and facilitate convenient parts turnover, neat stacking, and easy management. They are suitable for transportation, distribution, storage, and processing in factory logistics. They are resistant to bending and aging, have high load-bearing strength, and withstand tensile, compression, tearing, and high-temperature resistance. They are available in a variety of colors and can be molded into turnover box molds. Packaging box-type turnover boxes can be used for both turnover and finished product packaging; they are lightweight, durable, and stackable. However, existing foldable logistics turnover boxes have complex folding methods and steps, requiring users to spend considerable time and effort to operate them. Furthermore, existing folding boxes generally unlock by lifting the operating mechanism, which often leads to accidental operation by users. Accidental unlocking while in use is dangerous and provides a poor user experience. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a foldable logistics turnover box to solve the problems of complex structure and cumbersome operation steps in the existing logistics turnover boxes.

[0004] The present invention adopts the following solution: This application provides a foldable logistics turnover box, including a square base. The sides of the square base are respectively rotatably provided with two oppositely arranged first side plates and two oppositely arranged second side plates. The first side plates and the second side plates are adapted to rotate and switch between a flattened state and an upright state. The side of each first side plate is connected to the side of the adjacent second side plate so that when the upright state is reached, it together with the square base forms a cavity for accommodating goods.

[0005] Each of the two sides of the first side plate is provided with an elastic block. The movable end of the elastic block is adapted to press against the inner side of the adjacent second side plate when the second side plate is in the upright state, so as to limit the second side plate to the upright state. When the second side plate is in the upright state, its two sides are adapted to press against the inner side of the first side plate to restrict the first side plate from rotating inward.

[0006] A release assembly is provided on the first side plate. The release assembly is adapted to include an operating part that can move up and down and release rods connected to both sides of the operating part. The release rods are adapted to abut against the movable end of the elastic block, and the operating part is adapted to drive the release rods to push the elastic block out of the inner side of the second side plate when moving downward, so as to release the rotation restriction on the first side plate.

[0007] Furthermore, the operating member is movably disposed on the outside of the second side plate. The operating member has two elastic arms symmetrically arranged. The elastic arms are adapted to be connected to a fixed block disposed on the outside of the second side plate. The operating member is adapted to press the elastic arms against the fixed block when moving downward and generate a reverse elastic restoring force.

[0008] Furthermore, one end of the release rod is hinged to both sides of the operating member, and when the operating member moves downward, it is adapted to drive the other end of the release rod to move in the opposite direction to drive the elastic block to disengage from the second side plate.

[0009] Furthermore, the movable end of the elastic block includes a baffle surface, a first inclined surface, and a second inclined surface. The first inclined surface is adapted to slide in contact with the second side plate during the process of switching the second side plate from a folded state to an upright state. The second inclined surface is configured to be inclined upward along the direction of the first side plate toward the second side plate and is adapted to slide in connection with the end of the release rod so as to be able to move away from the second side plate under the sliding drive of the release rod. The baffle surface is adapted to press against the inner side surface of the second side plate when the second side plate is in the upright state to restrict the second side plate from rotating inward.

[0010] Furthermore, the end of the release rod is provided with a third inclined surface adapted to fit the second inclined surface.

[0011] Furthermore, the square base has baffles on its two opposite sides, and the baffle for mounting the first side plate is higher than the baffle for mounting the second side plate.

[0012] Furthermore, each sidewall has a T-shaped groove on its inner sidewall, and the bottom of the first side plate and the second side plate are provided with T-shaped blocks suitable for moving in the T-shaped groove.

[0013] Furthermore, an arc-shaped portion is provided at the connection between adjacent side panels to facilitate the switching of the first side panel from a folded-down state to an upright state.

[0014] Furthermore, the first side plate has protective edges parallel to the second side plate on both sides, and the protective edges are provided with guide holes. The outer edge of the second side plate is provided with a guide cone suitable for insertion into the guide hole.

[0015] Furthermore, a card holder is provided on the outer side of the first side plate or the second side plate.

[0016] Beneficial effects:

[0017] This invention features elastic blocks and a release mechanism on the first and second side plates, respectively. The elastic blocks restrict the movement of the second side plate, while simultaneously restricting the movement of the first side plate when the second side plate is upright, ensuring stable upright operation of both. The release mechanism allows the user to push the elastic blocks out of their limiting positions when forcefully moving the operating component downwards, enabling the second side plate to rotate and fall down. Similarly, the first side plate can be folded down after the second side plate is folded down, switching to the folded state. The downward driving mechanism effectively prevents the user's hand from pressing on the operating component when placing it on the second side plate, thus preventing the operating component from driving the release mechanism and pushing out the elastic blocks. This design is simple in structure, convenient to operate, and uses all plastic parts, effectively preventing the problems of easy damage and material contamination associated with using springs or other elastic components.

Detailed Implementation

[0031] Combination Figures 1 to 12 As shown, this embodiment provides a foldable logistics turnover box, including a square base 1. The sides of the square base 1 are respectively rotatably provided with two opposing first side plates 2 and two opposing second side plates 3. The first side plates 2 and the second side plates 3 are adapted to rotate and switch between a folded state and an upright state. The side of each first side plate 2 is connected to the side of the adjacent second side plate 3 so that when in the upright state, it together with the square base 1 forms a receiving cavity for accommodating goods.

[0032] Each of the two sides of the first side plate 2 is provided with an elastic block 23. The movable end 23 of the elastic block is adapted to press against the inner side of the second side plate 3 adjacent to it when the second side plate 3 is in the upright state, so as to limit the second side plate 3 in the upright state. When the second side plate 3 is in the upright state, its two sides are adapted to press against the inner side of the first side plate 2 to restrict the first side plate 2 from rotating inward.

[0033] A release assembly 4 is provided on the first side plate 2. The release assembly 4 is adapted to include an operating member 41 that can move up and down and a release rod 42 connected to both sides of the operating member 41. The release rod 42 is adapted to abut against the movable end of the elastic block 23. When the operating member 41 moves downward, it is adapted to drive the release rod 42 to push the elastic block 23 out of the inner side of the second side plate 3 so that the second side plate 3 is adapted to switch to a folded state.

[0034] Combination Figures 1 to 12 As shown in this embodiment, the "erected state" refers to the first side plate 2 and the second side plate 3 being perpendicular to the square base 1 and in a usable state. In the erected state, the first side plate 2 and the second side plate 3 restrict each other so that neither the first side plate 2 nor the second side plate 3 can be rotated or folded. The "folded state" refers to the first side plate 2 and the second side plate 3 being folded onto the square base 1 and laid flat on the plane of the square base 1, i.e., the folded state. The square base 1 has upward-facing guard edges 11 around its perimeter for mounting the first side plate 2 and the second side plate 3, and the guard edge 11 for mounting the first side plate 2 is higher than the guard edge for mounting the second side plate 3. The corresponding guard edges 11 are at the same height. A T-shaped groove 111 is provided on the inner wall of each guard edge 11, connecting to the top of the guard edge 11, allowing the first side plate 2 or the second side plate 3 to be inserted into the T-shaped groove 111 from the top. The bottom of both the first side plate 2 and the second side plate 3 is provided with a T-shaped block 21 adapted to move within the T-shaped groove 111. The T-shaped block 21 is adapted to be inserted from the top of the guard edge, and the T-shaped block 21 is interference-fitted with the narrowest part of the T-shaped groove 111, thus preventing the T-shaped block 21 from detaching from the T-shaped groove 111. However, the T-shaped block 21 can be detached from the T-shaped groove 111 under force, facilitating the disassembly and replacement of the side plate. By setting guard edges 11 at different heights, when the side plate is folded down, the second side plate 3 is positioned below the first side plate 2, preventing interference after folding. In addition, an arc-shaped portion is provided at the connection between adjacent side plates 11 to facilitate the switching of the first side plate 2 from a folded state to an upright state. Here, the first side plate 2 can rotate upward along the arc-shaped portion, improving the smoothness of rotation.

[0035] Combination Figure 2 , Figure 3 as well as Figures 7 to 12As shown, each of the two side plates of the first side plate 2 is provided with an elastic block 23. When the second side plate 3 is in the upright state, the inner side surface of the second side plate 3 is limited by the movable end 232 of the elastic block 23, so that the second side plate 3 cannot be switched to the folded state. Here, the elastic block 23 can be parallel to the plane where the first side plate 2 is located. The elastic block 23 includes an elastic strip 231 and a movable end 232. The movable end 232 is located at the end of the elastic strip 231. The movable end 232 is provided with a baffle surface 2323, a first inclined surface 2321 and a second inclined surface 2322. The first inclined surface 2321 is adapted to slide in contact with the second side plate 3 during the process of the second side plate 3 switching from the folded state to the upright state. The second inclined surface 2322 is set to be inclined upward along the direction from the first side plate 2 toward the second side plate 3, and is adapted to slide in connection with the end of the release rod 42, so as to move away from the second side plate 3 under the sliding drive of the release rod 42. That is, the first inclined surface 2321 faces the receiving cavity. When the second side plate 3 rotates from the inside to the outside, the edge of the second side plate 3 slides into contact with the first inclined surface 2321. During the rotation of the second side plate 3, the elastic strip 231 can be driven to deform outward. When the second side plate 3 is about to rotate to the vertical state, the elastic strip 231 reaches the maximum deformation. When the second side plate 3 rotates to the vertical state, the movable end 232 is located inside the second side plate 3, and the elastic strip 231 returns to its original shape. The baffle surface 2323 of the movable end 232 moves to the inside of the edge of the second side plate 3 to limit the second side plate 3 and prevent the second side plate 3 from rotating inward.

[0036] The end of the release rod 42 is connected below the movable end 232 of the elastic block 23 and slides in contact with the second inclined surface 2322. When the second inclined surface 2322 is subjected to an upward force, the elastic strip 231 will swing outward and the movable end 232 will gradually move away from the second side plate 3 towards the outside of the first side plate 2. When the baffle surface 2323 of the movable end 232 disengages from the second side plate 3, the baffle surface 2323 will no longer limit the second side plate 3. At this time, the second side plate 3 can be folded, and the first side plate 2 can also be folded inward because it is not blocked by the second side plate 3.

[0037] Combination Figure 2 , Figure 3 , Figure 5 as well as Figures 10 to 12As shown, the release assembly 4 is disposed on the outer side of the second side plate 3, specifically including an operating member 41 and a release rod 42. The operating member 41 is movably disposed on the outer side of the second side plate 3, and two elastic arms 411 are symmetrically arranged on the inner side of the operating member 41. The elastic arms 411 are adapted to connect to a fixing block 33 disposed on the outer side of the second side plate 3. When the operating member 41 moves downward under external force, the elastic arms 411 press against the fixing block 33, generating an upward elastic restoring force. Thus, when the user releases the force, the elastic arms 411 allow the operating member 41 to return to its original position. One end of the release rod 42 is hinged to both sides of the operating member 41. When the operating member 41 moves downward, it is adapted to drive the other end of the release rod 42 to lift upward and act on the second inclined surface 2322 of the elastic block 23, moving upward along the second inclined surface 2322. During the lifting process, it drives the movable end of the elastic block 23 away from the second side plate 3 to remove the rotation restriction on the second side plate 3. Specifically, a limit post 32 is also provided on the outer side of the second side plate 3. The limit post 32 is located below the middle part of the release rod 42 to form a lever fulcrum, so that when the operating member 41 moves downward, the other end of the release rod 42 can rotate along the lever fulcrum to lift upward. In one embodiment, a third inclined surface 421 adapted to fit the second inclined surface 2322 is provided at the end of the release rod 42.

[0038] Limiting surfaces 34 are provided on both sides of the second side plate 3, the limiting surfaces 34 facing the receiving cavity, and the end of the release rod 42 is located inside the limiting surface 34. When the second side plate 3 is in the upright state, the baffle surface 2323 of the movable end 232 is exactly pressed against the limiting surface 34.

[0039] Combination Figure 2 , Figure 3 as well as Figure 7 As shown, in one embodiment, the first side plate 2 has protective edges 22 parallel to the second side plate 3 on both sides. The protective edges 22 have guide holes 221, and the outer edge of the second side plate 3 has a guide cone 31 suitable for insertion into the guide hole 221. The protective edges 22 limit the second side plate 3 from flipping backward, improving its stability in the upright state. The guide cone 31 and the guide hole 221 enhance the stability of the connection between the second side plate 3 and the first side plate 2.

[0040] Combination Figure 1 , Figure 2 As shown, in another embodiment, a card holder 5 is provided on the outer side of the first side plate 2 or the second side plate 3, so that the user can conveniently place the card on the card holder 5 for identification.

[0041] Combination Figure 1 , Figure 4 As shown, in one embodiment, an upper cover 6 is also included. The upper cover 6 is adapted to cover the top of the first side plate 2 and the second side plate 3, thereby closing the upper opening of the receiving cavity. It can also be placed directly on the baffle 11 when the first side plate 2 and the second side plate 3 are in the folded-down state.

[0042] It should be noted that in this embodiment, all components can be made of plastic, making the logistics turnover box suitable for more occasions and more corrosion resistant.

[0043] This embodiment of the invention features elastic blocks 23 and release components 4 on the first side plate 2 and the second side plate 3, respectively. The elastic blocks 23 restrict the second side plate 3 from switching from an upright to a folded state, while the second side plate 3, when upright, also restricts the movement of the first side plate 2, ensuring stability for both sides. The release components 4 allow the user to push the movable end of the elastic blocks 23 out of its limit position when forcefully moving the operating element 41 downwards, allowing the second side plate 3 to rotate and fold down. Similarly, when the second side plate 3 is folded down, the first side plate 2 can also be folded down, switching to the folded state. The downward driving mechanism effectively prevents the user from accidentally pressing on the operating element 41 during movement, which could cause the operating element 41 to drive the release rod 42 and push out the elastic blocks 23. This design is simple in structure, convenient to operate, and uses only plastic parts, effectively preventing damage caused by springs or other elastic components, as well as damage from material contamination.

[0044] It should be understood that the above are only preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. All technical solutions that fall within the scope of the present utility model are protected by the present utility model.
