[0002] In current logistics transportation and warehousing management, transit containers, as a common loading and transfer device, are widely used for the temporary storage and turnover of various goods. Traditional transit containers mostly adopt a fixed structure with immovable doors, and the container body is often made of ordinary metal or plastic. Although they have a certain load-bearing capacity, they are significantly lacking in space utilization and ease of movement. These containers still occupy a large space when empty or in storage, increasing warehousing and transportation costs. In addition, most traditional transit containers are not equipped with moving devices and rely on forklifts or other external equipment for handling, which is inconvenient to operate and inefficient.

[0003] In existing technologies, fixed transfer boxes made of ordinary aluminum have welded or bolted doors that cannot be folded or rotated, resulting in a bulky box when not in use, occupying a large amount of storage and transportation space. Furthermore, these boxes lack casters, requiring forklifts or manual hydraulic trolleys for movement, thus limiting their flexibility. While the box material is mostly ordinary aluminum alloy, which is lighter than steel, its overall structural strength and load-bearing capacity are limited, making it prone to deformation under heavy loads or frequent use, affecting its service life and safety.

[0004] Therefore, there is an urgent need for a transfer device with a reasonable structure, easy folding and storage, convenient movement, and high strength and load-bearing capacity to solve the problems of large size, inconvenient movement, and insufficient material strength in the existing technology, so as to meet the needs of modern logistics for high efficiency, energy saving and space saving.

[0021] The present invention will be further described below with reference to specific embodiments, and the advantages and features of the present invention will become clearer as a result of the description. However, these embodiments are merely exemplary and do not constitute any limitation on the scope of the present invention. Those skilled in the art should understand that modifications or substitutions can be made to the details and form of the technical solution of the present invention without departing from the spirit and scope of the present invention, but all such modifications and substitutions fall within the protection scope of the present invention.

[0022] See Figures 1 to 8This utility model relates to a novel foldable transfer device, including a box body 1, a top cover 2, a door panel 3, casters 4 and a locking mechanism. The box body 1 is made of aviation aluminum profile. A bottom plate 11 is provided at the bottom of the box body 1, and at least two lifting rings 5 ​​are fixedly installed on the top. The top cover 2 is located on top of the housing 1, and has a lifting eye hole for the lifting ring 5 to pass through. Several door panels 3 are provided, each with its upper or lower side hinged to the housing 1 via a door panel pivot 31. When the door panel is in a vertical position, it supports the top cover 2. Casters 4 are provided at the bottom of the housing 1, each caster 4 being rotatably mounted to the bottom of the housing 1 via a caster pivot 41. The locking mechanism includes a top cover lock 61 on the top cover 2 for locking the housing 1 to the top cover 2, a side lock 62 on the housing 1 for locking adjacent door panels, and a rotary lock 63 on the top cover 2 or housing 1 that engages with the positioning hole 51 of the lifting ring 5. A lifting pin lock is also provided on the bottom plate 11.

[0023] Based on the above structural design, the following advantages are achieved: With its compact structure and foldable design, it saves a significant amount of space. The door panels are hinged via a pivot, allowing it to be folded flat, greatly reducing its volume when empty, making it easy to store and transport.

[0024] Easy to move and adaptable to various usage scenarios. The casters are retractable via a pivot, allowing for flexible movement and easy stacking, reducing reliance on external equipment such as forklifts.

[0025] The locking mechanism is comprehensive, safe, and reliable. The top cover lock, side lock, and rotary lock work together to achieve multi-point locking of the top cover, door panel, and lifting rings, effectively preventing shock and detachment, and ensuring stability during transportation.

[0026] The overall structure is lightweight yet robust. It uses aerospace-grade aluminum profiles, which reduces weight while ensuring high strength and excellent load-bearing capacity, making it especially suitable for frequent transfers and stacking.

[0027] It boasts high functional integration and strong practicality. The lifting ring combines lifting and stacking positioning functions, working in conjunction with the rotary lock to improve operational efficiency and the overall versatility of the equipment.

[0028] Four uprights 12 are arranged along the circumference of the box body 1. The four uprights 12 are hollow tubes integrally extruded from aerospace aluminum. This structure uses hollow tubes integrally extruded from aerospace aluminum as uprights, which significantly reduces the overall weight while greatly enhancing the structural strength, rigidity and load-bearing stability of the box body.

[0029] The bottom plate 11 of the housing 1 is also provided with a forklift slot 7 for accommodating forklift channel steel.

[0030] It also includes a caster locking pin 42 that is linked to the caster shaft 41, and the bottom plate of the housing 1 is provided with a pin hole 43 that mates with the caster locking pin 42. Through the cooperation of the caster locking pin and the pin hole, the rotational position of the caster can be mechanically locked, ensuring that the caster remains stable in the unfolded or retracted state, effectively preventing accidental movement or return to its original position during transportation or stacking, and enhancing the safety and reliability of the equipment.

[0031] There are four lifting rings, which are evenly arranged along the circumference of the box.

[0032] The rotary lock 63 includes a rotatable control lever and a locking lever linked to the control lever. The axis of the locking lever coincides with the axis of the positioning hole on the lifting ring. Through the linkage design of the control lever and the locking lever, and by aligning the axis of the locking lever with the axis of the positioning hole on the lifting ring, the rotary lock and the lifting ring can be quickly and accurately aligned and locked. The operation is labor-saving and the connection is reliable, effectively avoiding misalignment and jamming during the locking process.

[0033] The aerospace aluminum profile is made of 7-series aluminum alloy.

[0034] The working principle and process of the novel foldable transfer device described in this utility model are as follows: First, when unfolded for use, the operator rotates the folded door panel 3 upwards to a vertical position via the door panel pivot 31, making it stand up and support the top cover 2. Then, by operating the side lock 62 on the housing 1, the adjacent door panels 3 are locked together, forming a stable housing enclosure structure. The top cover 2 is fitted onto the lifting ring 5 on the top of the housing via its lifting ring hole and is locked and secured to the housing 1 by the top cover lock 61, ensuring that the top cover will not accidentally shift.

[0035] For the mobility function, the operator can rotate the stowed caster 4 90 degrees to the lowered position via the caster pivot 41, and then insert the caster locking pin 42 to engage with the pin hole 43 on the base plate, mechanically locking the caster in the working position. At this time, the transfer device can move freely with the help of the casters. If forklift transportation is required, the forklift forks can be inserted into the specially designed forklift slot 7 on the base plate 11 for operation.

[0036] When hoisting or stacking is required, the four evenly distributed lifting rings 5 ​​on the top of the container can be used to insert into the hoisting equipment or to engage with the lifting pins at the bottom of the upper container. By rotating the control lever of the rotary lock 63, the locking rod is driven to rotate and precisely insert into the positioning hole 51 of the lifting ring 5, thereby achieving fast and reliable locking and ensuring stability and safety during stacking or hoisting.

[0037] When folding and storing is required, operate in the reverse order: first open each locking mechanism, rotate the casters 90 degrees through the pivot and retract them and fix them with the locking pin, then lay the door panel 3 outward around the door panel pivot 31, which can significantly reduce the volume of the entire device and facilitate storage and transportation.

[0038] The entire housing and the one-piece extruded aerospace aluminum column provide lightweight and high-strength structural characteristics, ensuring smooth and stable operation and protecting the structural integrity of the device under heavy loads.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
