Description

Technical Field

[0001] This utility model relates to the technical field of container tilt-down door structures, and more particularly to a container structure with a tilt-down door. Background Technology

[0002] As a key container enclosure structure, the development of container tilt-down doors revolves around three core requirements: cargo handling efficiency, sealing security, and ease of operation. Traditional container doors mostly adopt a side-opening design, but in specific application scenarios such as bulk cargo handling, forklift operations, or space-constrained yards, side-opening doors have limitations such as large opening space and inconvenient operation. Therefore, tilt-down door structures have emerged. This structure is usually connected to the bottom of the container body with a high-strength steel door panel and hinges, and uses gravity to achieve the natural tilting of the door body to form a temporary loading and unloading ramp or working platform, which significantly simplifies the loading and unloading process.

[0003] The application of side beams and hinge structures in containers mainly enhances the container's load-bearing capacity and facilitates opening and closing. Side beams provide strong support and stability, ensuring the safety and durability of the container during transportation, especially when subjected to heavy loads or external impacts. Hinges allow container doors to open flexibly, facilitating loading and unloading of goods, while ensuring good sealing and protective performance when closed.

[0004] In the existing technology, most flip-down door structures have problems such as unevenness with the floor and excessive gap between the door and the bottom side beam when flipping. The gap between the flipped door and the floor makes it impossible for the door to fall stably, and it cannot achieve the proper sealing or support function. As a result, it can only be used as a door when it is upright, and it cannot fully utilize the flip-down or closing function that it should have in its design. Utility Model Content

[0005] In view of the problem that existing downward-opening door structures can only function as doors, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a container structure with a downward-opening door, which can be used as an auxiliary platform to temporarily carry some goods and equipment when not in transit.

[0007] To solve the above technical problems, this utility model provides the following technical solution: a container structure with a downward-opening door, including a top side beam, container corner posts symmetrically fixed below both ends of the top side beam, a splicing bottom side beam provided below the two container corner posts, a plurality of downward-opening door hinge assemblies provided at equal intervals on one side of the splicing bottom side beam, and a downward-opening door corrugated plate that rotates vertically along the rotation axis of the downward-opening door hinge assembly provided on the opposite inner side of the two container corner posts, and a gap exists between the upper and lower ends of the downward-opening door corrugated plate and the top side beam and the splicing bottom side beam;

[0008] The hinge assembly for the folding door includes a hinge base, which is welded to one side surface of the spliced ​​bottom side beam. A stainless steel hinge pin is provided on the hinge base. A hinge sleeve is fitted inside the hinge base on the surface of the stainless steel hinge pin. A hinge plate reinforcing rib is fixed on the surface of the hinge sleeve. A hinge plate body is fixed inside the hinge plate reinforcing rib. The inner side of the hinge plate body is fixedly connected to the lower part of the folding door corrugated plate.

[0009] As a preferred embodiment of the container structure with a downward-opening door described in this utility model, the rotation angle of the hinge sleeve is 0° to 90°.

[0010] As a preferred embodiment of the container structure with a downward-opening door described in this utility model, sealing strips are fixed at both ends of the corrugated plate of the downward-opening door along the height direction.

[0011] As a preferred embodiment of the container structure with a downward-opening door described in this utility model, the distance between the sealing strip of the corrugated plate of the downward-opening door near the bottom side beam and the bottom side beam is 56mm to 60mm.

[0012] As a preferred embodiment of the container structure with a downward-opening door described in this utility model, the splicing bottom side beam includes an upper wing plate and a lower wing plate of the bottom side beam. An inner web plate of the bottom side beam is fixed on the inner side between the upper wing plate and the lower wing plate of the bottom side beam, and an outer web plate of the bottom side beam is fixed on the outer side between the upper wing plate and the lower wing plate of the bottom side beam.

[0013] As a preferred embodiment of the container structure with a downward-opening door described in this utility model, the top of the upper wing plate of the bottom side beam is fixed with a water-repellent slope, and the slope of the water-repellent slope is arranged opposite to the corrugated plate of the downward-opening door.

[0014] As a preferred embodiment of the container structure with a downward-opening door described in this utility model, when the corrugated plate of the downward-opening door is arranged parallel to the anti-water slope, the top surface of the corrugated plate of the downward-opening door and the top surface of the anti-water slope are always on the same horizontal line.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects:

[0016] 1. This utility model can be used as an auxiliary platform. After the side door is flipped down 90 degrees, its upper surface is flush with the side beam and the floor inside the box. After flipping, the gap between it and the bottom side beam is very small. When used as an auxiliary platform, it greatly reduces the impact of dragging goods. At the same time, the reinforced hinge structure can make the flip-down door have good load-bearing strength when used as a platform, and can temporarily support some goods and equipment when not in transport.

[0017] 2. In this utility model, the bottom side beam adopts a thick plate splicing structure, which effectively solves the problem of insufficient structural strength of the bottom side beam of the side-opening door. The double web structure gives the bottom side beam better torsional strength. The outer web can be flexibly adjusted in positioning size according to the gap between the selected flip-down door and the bottom side beam.

[0018] 3. The anti-water slope structure of this utility model can prevent leaking rainwater from flowing into the box. Attached Figure Description

[0025] 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.

[0026] Example 1

[0027] Reference Figures 1-2 This is the first embodiment of the present invention, which provides a container structure with a flip-down door. The container structure with a flip-down door includes a top side beam 1, container corner posts 2 are symmetrically fixed below both ends of the top side beam 1, a splicing bottom side beam 3 is provided below the two container corner posts 2, a plurality of flip-down door hinge assemblies 4 are provided at equal intervals on one side of the splicing bottom side beam 3, and a flip-down door corrugated plate 5 is provided on the opposite inner side of the two container corner posts 2, which rotates vertically along the rotation axis of the flip-down door hinge assembly 4. There are gaps between the upper and lower ends of the flip-down door corrugated plate 5 and the top side beam 1 and the splicing bottom side beam 3.

[0028] The hinge assembly 4 for the folding door includes a hinge seat 401, which is welded to one side surface of the splicing bottom beam 3. A stainless steel hinge pin 402 is provided on the hinge seat 401. A hinge sleeve 403 is fitted inside the hinge seat 401 on the surface of the stainless steel hinge pin 402. A hinge plate reinforcing rib 404 is fixed on the surface of the hinge sleeve 403. A hinge plate body 405 is fixed inside the hinge plate reinforcing rib 404. The inside of the hinge plate body 405 is fixedly connected to the bottom of the folding door corrugated plate 5.

[0029] The hinge base is directly welded to the bottom side beam, ensuring a firm connection that can withstand the weight of the door panel and the impact of operation.

[0030] The combination of "stainless steel hinge pins" and "hinge sleeves" provides a reliable rotation axis, reduces friction, ensures smoothness during long-term use, and the stainless steel material is corrosion resistant.

[0031] The "hinge plate reinforcing rib" greatly enhances the strength and rigidity of the connection area between the hinge plate body and the door panel, preventing the hinge plate from deforming or tearing due to long-term load or external force, and improving the service life and reliability of the entire hinge system.

[0032] As a component directly connected to the door panel, the hinge plate body effectively transmits the force of the door panel to the hinge pin and base through the reinforcing ribs and sleeves, with a clear and reasonable force flow path.

[0033] The hinge sleeve 403 has a rotation angle of 0° to 90°;

[0034] This prevents the door from opening excessively, avoiding collisions with the cabinet or other components, and also makes it easier for the operator to judge the opening and closing status of the door.

[0035] Sealing strips 6 are fixed at both ends of the corrugated plate 5 of the flip-down door along the height direction;

[0036] When the door is closed, the sealing strip is compressed, which effectively seals the gaps between the door panel and the top and bottom side beams, providing rainproof, dustproof, and moisture-proof protection for the goods inside the box.

[0037] The distance between the sealing strip 6 of the corrugated plate 5 of the flip-down door and the bottom side beam 3 is 56mm to 60mm.

[0038] After flipping, the gap between it and the bottom side beam is very small, which greatly reduces the impact of dragging goods when it is used as an auxiliary platform.

[0039] Example 2

[0040] Reference Figures 1-4This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the splicing bottom side beam 3 includes an upper wing plate 301 and a lower wing plate 304. An inner web plate 302 of the bottom side beam is fixed on the inner side between the upper wing plate 301 and the lower wing plate 304, and an outer web plate 303 of the bottom side beam is fixed on the outer side between the upper wing plate 301 and the lower wing plate 304.

[0041] With extremely high bending and torsional stiffness, it can withstand the pressure from heavy-duty downward-opening doors and the fatigue stress from frequent operation, ensuring the long-term structural stability of the entire lower edge of the door frame; the sturdy bottom side beam provides a very stable base for welding the hinge seat, further enhancing the reliability of the hinge connection.

[0042] The top of the upper flange 301 of the bottom side beam is fixed with a water-repellent slope 7, and the slope of the water-repellent slope 7 is set opposite to the corrugated plate 5 of the flip-down door.

[0043] The slope of the backflow slope can guide water to drain quickly to both sides instead of accumulating in the gaps, reducing the risk of rainwater seeping into the tank.

[0044] When the corrugated plate 5 of the flip-down door is set parallel to the anti-water slope 7, the top surface of the corrugated plate 5 of the flip-down door and the top surface of the anti-water slope 7 are always on the same horizontal line.

[0045] This ensures that the door panel can press the sealing strip with uniform pressure to form an effective sealing surface, so that the closed door panel is flush with the outline of the box, resulting in a neat and beautiful appearance, while also facilitating the loading, unloading and stacking of goods.

[0046] The remaining structure is the same as that in Example 1.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
