Description

Technical Field

[0001] This utility model relates to the technical field of hinge plate connection structure, specifically to a door hinge plate connection mechanism for shipping containers. Background Technology

[0002] Shipping containers are box structures used for loading cargo during shipping. They are usually rectangular in shape and equipped with double doors. The doors are connected to the container body by hinges, which facilitate the opening and closing of the doors and ensure the storage of goods inside the container as well as theft prevention.

[0003] Current hinges are mostly exposed, and the main turning point is outside the container. This means that the door panel can be disassembled simply by cutting off the turning point, which reduces the safety of the container. Therefore, a door hinge panel connection mechanism for shipping containers is proposed. Utility Model Content

[0004] The technical solution adopted by this utility model to solve the technical problem is: a door hinge plate connection mechanism for shipping containers, including a box body, three inner slots are provided on the opposite side walls of the box body, an inner connecting plate is inserted into each inner slot, a hinge plate is rotatably connected to one end of the inner connecting plate, and an outer connecting plate is rotatably connected to the end of the hinge plate away from the inner connecting plate. A door panel is provided on one side of the box body, and a connecting plate is fixedly connected to the side wall of the door panel. The outer connecting plate is inserted into the connecting plate, and the internal structure of the connecting plate is the same as that of the inner slots.

[0005] As a preferred technical solution of this utility model, both the inner plate and the outer plate are T-shaped structures. The inner plate is inserted into the inner slot, and the outer plate is inserted into the connecting plate. Studs are evenly provided on the inner slot and the connecting plate, and screw holes are provided on the sidewalls of the inner slot and the connecting plate opposite to the studs.

[0006] As a preferred technical solution of this utility model, the inner slot and the outer plate are provided with a through hole at the position opposite to the insertion hole, and a stud is inserted into the insertion hole, with one end of the stud threaded into the corresponding screw hole.

[0007] As a preferred embodiment of this utility model, one side of the hinge plate has a U-shaped structure, and both ends are fixedly connected to docking posts. A fixing post is fixedly connected between the opposite sidewalls of the two docking posts, and one end of the inner plate is rotatably connected to the fixing post.

[0008] As a preferred embodiment of this utility model, the hinge plate is rotatably connected to a rotating shaft via a torsion spring on one side of its side away from the docking post. A driven plate is fixedly connected to one side of the rotating shaft. A rotating post is rotatably connected to the lower edge of the driven plate away from the rotating shaft. The outer plate is rotatably connected to the rotating post through one end of its side.

[0009] This utility model has the following advantages: An inner slot is opened in the cabinet, and a connecting plate is fixed on the door panel. The inner connecting plate is then inserted into the inner slot and tightened with a stud. The outer connecting plate is then inserted into the connecting plate and tightened with a stud as well, thus completing the connection between the cabinet and the door panel. Since the stud is located inside the cabinet, it cannot be disassembled from the outside, improving safety. When the door panel is closed, the outer connecting plate will first rotate along the rotating column. When the cabinet is closed to a certain angle, the rotating shaft will drive the driven plate to rotate, which will bring the door panel closer to the opening of the cabinet. This minimizes the distance between the door panel and the opening of the cabinet, preventing the hinge plate itself from being damaged and causing the cabinet to be disassembled, thus reducing the safety of the cabinet. If necessary, rubber gaskets can be connected to the cabinet and the door panel to further improve the sealing performance. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] Please refer to the following: Figure 1-3 This utility model discloses a door hinge plate connection mechanism for shipping containers, including a container body 1. Three inner slots 7 are provided on the opposite side walls of the container body 1. An inner connecting plate 2 is inserted into each inner slot 7. A hinge plate 3 is rotatably connected to one end of the inner connecting plate 2. An outer connecting plate 6 is rotatably connected to the end of the hinge plate 3 away from the inner connecting plate 2. A door panel 4 is provided on one side of the container body 1. A connecting plate 5 is fixedly connected to the side wall of the door panel 4. The outer connecting plate 6 is inserted into the connecting plate 5. The internal structure of the connecting plate 5 is the same as that of the inner slots 7.

[0016] Both the inner plate 2 and the outer plate 6 are T-shaped structures. The inner plate 2 is inserted into the inner slot 7, and the outer plate 6 is inserted into the connecting plate 5. Studs 9 are evenly distributed on the inner slot 7 and the connecting plate 5. Screw holes are formed on the side walls of the inner slot 7 and the connecting plate 5 opposite to the studs 9. Insertion holes 8 are formed on the inner slot 7 and the outer plate 6 at positions opposite to the insertion holes 8. Studs 9 are inserted into the insertion holes 8, and one end of the studs 9 is threaded into the corresponding screw holes.

[0017] The technical advantages of this solution are as follows: Because the inner slot 7 and the connecting plate 5 are located inside the container body 1 and the door panel 4, all the connecting parts are inside when the door panel 4 is closed. This prevents the connecting parts from being affected by the outer wall, thereby improving the safety of the container. Furthermore, by inserting the inner connecting plate 2 into the inner slot 7, then inserting the outer connecting plate 6 into the connecting plate 5, and finally tightening it with the studs 9, the door panel 4 can be connected to the container body 1 more conveniently. It also facilitates disassembly and maintenance, improving the ease of use. In addition, because it is a double-door structure, even if the studs 9 on the outer connecting plate 6 are damaged for a short time, it will not affect the stability of the door panel 4, because the connecting plate 5 needs to be detached from the outer connecting plate 6 by sliding. The opening direction of the connecting plate 5 and the double-door structure will also limit each other after they are closed.

[0018] One side of the hinge plate 3 has a U-shaped structure, and both ends are fixedly connected to the docking post 10. A fixed post 11 is fixedly connected between the opposite side walls of the two docking posts 10. One end of the inner plate 2 is rotatably connected to the fixed post 11. The side edge of the hinge plate 3 away from the docking post 10 is rotatably connected to the rotating shaft 12 through a torsion spring. A driven plate 13 is fixedly connected to one side of the rotating shaft 12. A rotating post 14 is rotatably connected to the lower edge of the driven plate 13 away from the rotating shaft 12. The outer plate 6 is rotatably connected to the rotating post 14 through one end of the outer plate 6.

[0019] The technical effect of this solution is as follows: when the door panel 4 rotates to close, it will first drive the outer plate 6 to rotate along the rotating column 14. When the door panel 4 is closed to a certain angle, the torsion spring will be activated to drive the rotating shaft 12 to rotate. As the rotating shaft 12 rotates, it will also drive the driven plate 13 to rotate. As the driven plate 13 rotates, it will pull the door panel 4 to move, thereby bringing the door panel 4 closer to the opening of the container 1. This will minimize the gap between the door panel 4 and the opening of the container 1, thereby shielding and protecting the hinge plate 3 and various connection nodes, thus improving the overall safety of the container.

[0020] Specifically, during installation, the inner plate 2 is first inserted into the inner slot 7, and then the studs 9 are tightened. Next, the outer plate 6 is inserted into the connecting plate 5, and the studs 9 are tightened simultaneously. This completes the connection between the door panel 4 and the container body 1. Because all the connection points are internal, when the door panel 4 is closed, all connection points and the hinge plate 3 itself can be hidden inside the container, thus protecting them and preventing external influences, thereby improving the overall safety of the container. Furthermore, as the door panel 4 closes, the outer plate 6 will rotate accordingly. When column 14 rotates, the torsion spring will activate after the door panel 4 rotates to a certain angle. The torsion spring drives the rotating shaft 12 to rotate, which in turn drives the driven plate 13 to move. This causes the door panel 4 to move closer to the opening of the box 1, thereby reducing the distance between the door panel 4 and the opening of the box 1. This allows the hinge plate 3 and the connecting nodes to be covered and hidden. Because the distance is reduced, external influences on the hinge plate 3 can be prevented, improving safety. If necessary, sealing gaskets can be connected to the door panel 4 and the box 1 to further improve the sealing between the box 1 and the door panel 4.

[0021] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0022] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
