Description

Technical Field

[0001] This utility model relates to the field of frame boxes, specifically a multifunctional folding frame box. Background Technology

[0002] Pulp carriers and bulk carriers are important forms of water transport, often used in the logistics sector to carry heavy or large-volume bulk cargo such as steel coils and tonnes. A single steel coil can weigh several tons and is cylindrical in shape, making it prone to rolling when stacked. Tonsnes, on the other hand, contain large quantities of bulk cargo (such as ore and grain), with each tonne typically weighing from several hundred kilograms to over a ton, and are also quite large in size.

[0003] However, in the actual transportation of these goods in existing cargo holds, the use of conventional collapsible frame containers (with end frames that can only rotate 90 degrees) and the mere presence of a single-layer base platform result in particularly low space utilization. Specifically, to avoid damage to goods during transportation due to shaking or compression—for example, rolling steel coils may cause collision deformation, and excessively high stacking of ton bags may lead to breakage and leakage due to heavy pressure—goods are often placed in a single layer laid flat, or at most, stacked in a low layer. This stacking method results in a severe waste of vertical space within the cargo hold, with a significant amount of usable height remaining unused.

[0004] Taking the cargo hold of a common bulk carrier as an example, its vertical height can usually reach several meters. However, due to the above-mentioned limitations, the actual height used for loading cargo is often only one-third or even less of the total height of the cargo hold, which greatly reduces the cargo capacity of a single transport and increases the transportation cost per unit of cargo.

[0005] If two conventional collapsible frame containers are stacked vertically to avoid wasting upper cargo space, more collapsible frame containers will be needed, increasing material consumption and ship load, while inevitably reducing cargo capacity. Utility Model Content

[0006] The purpose of this utility model is to provide a multifunctional folding frame box with a convenient disassembly of a two-layer standardized platform, which can increase the loading capacity while protecting the cargo at the bottom layer, and is compatible with standard containerized operating procedures.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional folding frame box, comprising a base platform, corner posts, and a hinge device. The base platform is placed horizontally, with platform corner pieces fixed to the lower sides of its ends. The hinge device is hinged to the two ends of the base platform and located above the platform corner pieces. The corner posts are slidably disposed inside the hinge device, and the corner posts rotate with the hinge device, enabling them to be folded or perpendicular to the base platform. The corner posts and the hinge device can selectively form a fixed connection at both ends of the corner posts.

[0008] Preferably, the hinge device has a fixing pin hole, and the two ends of the corner post have positioning pin holes. When the positioning pin hole at either end is opposite to the fixing pin hole, the corner post can be fixed to the hinge device using a pin.

[0009] Preferably, the corner post has multiple sets of positioning pin holes equidistantly spaced along its length.

[0010] Preferably, the hinge device includes two parallel hinge plates, and the end of the base platform includes a hinge seat located between the two hinge plates. The two hinge plates are connected to the hinge seat via the same hinge shaft, which is along the width direction of the base platform.

[0011] Preferably, the hinge device further includes two parallel limiting plates, which are perpendicular to the hinge plates and fixed between the two hinge plates. The limiting plates and the hinge plates form a sliding groove, and the corner post slides in the sliding groove.

[0012] Preferably, both ends of the corner post are fixed with corner pieces, and the outer contour of the corner pieces is larger than the sliding groove hole.

[0013] Preferably, an end beam is fixed between the two hinge devices.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: By changing the connection structure of the corner posts, hinge devices and base platform in a conventional folding frame box, this utility model uses the corner posts as supports for the base platform, which can adjust the height of the base platform from the ground and realize double-layer cargo loading of the frame box.

[0019] This utility model discloses a multifunctional folding frame box, which is an improvement on the conventional folding frame box. By redesigning the connection mechanism at both ends, a function that allows the corner posts to change vertically has been added.

[0020] See Figures 1 to 4 This embodiment includes a base platform 1, corner posts 2, and a hinge device 3. The base platform 1 is placed horizontally, with platform corner pieces 4 fixed to the lower sides of its ends. The hinge device 3 is hinged to the two ends of the base platform 1 and located above the platform corner pieces 4. The corner posts 2 are slidably disposed inside the hinge device 3. The corner posts 2 rotate with the hinge device 3 and can be folded or perpendicular to the base platform 1. The corner posts 2 and the hinge device 3 can selectively form a fixed connection at both ends of the corner posts 2. Specifically:

[0021] An end beam 6 is fixed between two hinge devices 3 located at the same end of the base platform 1. The end beam 6 serves as the main load-bearing and connecting foundation component of the hinge device 3, providing a mounting support for other components and transmitting and bearing external forces. The hinge device 3 includes two parallel hinge plates 31 and two parallel limiting plates 32. The hinge plates 31 are located on one side of the end beam 6 and fixed thereto.

[0022] The end of the base platform 1 includes a hinge seat 11, located directly above the platform corner piece 4. The hinge seat 11 is situated between two hinge plates 31, which are connected to the hinge seat 11 via the same hinge shaft 7, which runs along the width of the base platform 1. A limiting plate 32 is perpendicular to the hinge plates 31 and fixed between them, forming a sliding slot with the hinge plates 31. The corner post 2 slides within this slot. Corner pieces 5 are fixed to both ends of the corner post 2, with the outer contour of each corner piece 5 larger than the sliding slot. Constrained by the corner pieces 5 at both ends, the corner post 2 cannot disengage from the sliding slot. Both the corner pieces 5 and the platform corner piece 4 are standard corner piece structures used in the container industry for contact with external components.

[0023] The hinge plate 31 is an irregularly shaped flat plate with an irregular L-shaped main body. It consists of two mutually perpendicular plate parts and can be considered as a specific contour of the irregular L-shape formed by cutting and rounding corners on a rectangular flat plate. The two mutually perpendicular plate parts are the hinge part 311 and the sliding part 312. The hinge part 311 is connected to the hinge seat 11 through the hinge shaft 7, and the sliding part 312 serves as the sidewall of the sliding groove and fits against the corner post 2.

[0024] The corner post 2 and the end beam 6 together form the frame structure of this embodiment. The hinge plate 31 serves as a rotating connection structure, allowing the frame structure to rotate around the hinge axis 7, thus enabling the frame structure to switch between folding and unfolding actions. Thanks to the special structure of the hinge plate 31, the frame structure can be folded and fitted onto the top of the base platform 1. At this time, the hinge part 311 is located beside the base platform 1, and the sliding part 312 is located above the hinge part 311. (See reference...) Figure 3 Meanwhile, the rotation of the hinge plate 31 is restricted by the platform corner piece 4 at the bottom of the base platform 1. When the hinge part 311 is directly above the platform corner piece 4, the sliding part 312 and the frame structure are perpendicular to the base platform 1. At this time, the frame structure unfolds. (See reference...) Figure 1 and Figure 4 .

[0025] A round pin assembly 8 is provided laterally at the end of the base platform 1. When the corner column 2 is unfolded and needs to be kept in a stable state, the round pin assembly 8 is inserted into the corresponding locking hole of the hinge plate 31 and cooperates with the hinge plate 31 to lock the hinge device 3, restricting the relative rotation of the entire hinge device 3 and the corner column 2, playing a stable locking role, and ensuring that the structure will not be accidentally folded or deformed under load and other working conditions.

[0026] The hinge plate 31 has a fixing pin hole 33, and the corner post 2 has positioning pin holes 21 at both ends. When the positioning pin hole 21 at either end is aligned with the fixing pin hole 33, the corner post 2 can be fixed to the hinge device 3 using a pin. When the corner post 2 is perpendicular to the base platform 1, if the hinge device 3 is fixed to the bottom end of the corner post 2, the folding frame box is used as a conventional folding frame box. (See reference...) Figure 1 If the hinge device 3 is fixed to the top of the corner post 2, the corner post 2 supports the base frame platform 1, and its bottom corner piece 5 contacts the ground. The base frame platform 1 and the ground form a double-layer cargo platform. (See reference...) Figure 4 .

[0027] To enhance the practicality of the frame box, in addition to the positioning pin holes 21 at both ends, multiple sets of positioning pin holes 21 are equidistantly provided along the length of the corner post 2, which are not shown in the figure. Thus, when the corner post 2 is perpendicular to the base platform 1, the corner post 2 and the hinge device 3 can also selectively form a fixed connection at other positions of the corner post 2 to achieve different height positions of the base platform 1 and the corner post 2, so as to adapt to the needs of different loading heights.

[0028] When the entire frame box needs to be folded, the bottom end of the corner post 2 needs to be fixed to the hinge plate 31 with a pin to temporarily position the corner post 2 and enhance the stability during the rotation process, so that after the frame structure is folded, the corner post 2 can be completely above the base platform 1 and will not protrude from the end of the base platform 1.

[0029] In this embodiment, the frame structure is unfolded, keeping the corner posts 2 upright. At this time, it can be used as a regular folding frame box. If it is necessary to further increase the height of the base platform 1, the operation continues: first, release the temporary positioning of the corner posts 2 by the pins, and then use a forklift to lift the base platform 1 upward. During the rise of the base platform 1, the four corner posts 2 will automatically slide downward due to gravity and mechanical structure limitations. When the base platform 1 rises to the highest point, use the pins to fix the base platform 1 to the top of the corner posts 2. At this time, the space below the base platform 1 can be used to store bulk non-stackable goods such as steel coils and pulp, and the base platform 1 can be used as an additional platform to stack other goods, realizing a double-layer cargo carrying function.

[0030] In summary, this utility model adjusts the height of the base platform 1 relative to the ground by using movable corner posts 2, which makes the frame container more capable of loading, more adaptable to different loading environments, and makes efficient use of space. Steel coil ships and pulp ships can achieve double-layer cargo loading, thereby improving the cargo transportation volume and the economic benefits of logistics transportation.
