Description

Technical Field

[0001] The utility model relates to the technical field of hinges, in particular to a hinge for military containers. Background Art

[0002] In the military field, containers are widely used. As a key component connecting various parts of the container, the container hinge cannot be ignored. Military containers usually need to operate in various harsh environments, so there are extremely high requirements for the quality and performance of the hinges. Military container hinges must be strong and durable to withstand vibrations, impacts, and heavy loads during transportation. In addition, military container hinges should also have anti-corrosion and anti-wear characteristics to adapt to various complex usage environments. To meet these requirements, military container hinges are usually made of high-strength materials and undergo strict quality inspections and tests. In terms of design, military container hinges need to consider the structural characteristics and usage requirements of the container to ensure convenient installation and flexible operation.

[0003] However, during the installation of existing military container hinges, one end of the hinge needs to be connected to the container door first, and then the container door is lifted to align the installation hole at the other end of the hinge with the hinge installation hole on the military container. Subsequently, bolts are inserted into the installation holes for installation. This installation method of the hinge also requires at least one person other than the installer to support the container door during installation. It is difficult for a single person to smoothly install the container door onto the container through the hinge, which is somewhat inconvenient to use. At the same time, during use, when the ground is inclined, under the action of the gravity of the container door, the hinge will be driven to rotate, resulting in the rotation of the opening angle of the door. To maintain the opening angle of the military container door, another object needs to be found to block the container door, which is somewhat inconvenient to use. Summary of the Utility Model

[0004] The utility model provides a hinge for military containers to solve the problems raised in the above background art.

[0005] To solve the above technical problems, the technical solution adopted by the utility model is:

[0008] A further improvement of the technical solution of the present utility model lies in that: on the side of the first fixing plate away from the military container, there is a fixedly connected mounting plate. Inside the mounting plate, there is a rotatable connecting rotating shaft. On the surface of the rotating shaft, there is a fixedly connected first fixed tooth. At the top of the rotating shaft, there is a socket slot opened.

[0009] A further improvement of the technical solution of the present utility model lies in that: on one side of the first fixing plate, there is a fixedly connected guiding rod. On the surface of the guiding rod, there is a lapped pressing plate. On one side of the pressing plate, there is a fixedly connected spring. The end of the spring away from the pressing plate is fixedly connected to the side of the first fixing plate close to the guiding rod.

[0010] A further improvement of the technical solution of the present utility model lies in that: on the side of the pressing plate away from the spring, there is a fixedly connected second fixed tooth. The surface of the second fixed tooth meshes with the surface of the first fixed tooth. At the bottom of the rotating shaft, there is a threadedly connected fixing screw.

[0011] A further improvement of the technical solution of the present utility model lies in that: the hinge socket part includes a second fixing plate. One side of the second fixing plate lapps with one side of the container door. Inside the second fixing plate, there is a socketed second bolt. One end of the second bolt is threadedly connected to the inside of the container door.

Detailed implementation manners

[0022] The following further describes the present utility model in detail with reference to embodiments: Embodiment 1

[0023] As Figures 1-5 shown, the present utility model provides a hinge for a military container, including a military container 1. A hinge fixing part 2 is fixedly connected to the surface of the military container 1. A hinge insertion part 3 is inserted into the inside of the hinge fixing part 2. A container door 4 is fixedly connected to one side of the hinge insertion part 3.

[0024] In this embodiment, during use, by rotating the container door 4, the rotating arm 33 drives the insertion rod 35 to rotate, and the rotating shaft 24 rotates, thereby completing the opening and closing of the bottom container door 4. Embodiment 2

[0025] As Figures 1-5As shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, the hinge fixing part 2 includes a first fixing plate 21. One side of the first fixing plate 21 is fixedly connected to one end of the military container 1. A first bolt 22 is inserted into the first fixing plate 21. One end of the first bolt 22 is threadedly connected to the inside of the military container 1. A mounting plate 23 is fixedly connected to the side of the first fixing plate 21 away from the military container 1. A rotating shaft 24 is rotatably connected to the inside of the mounting plate 23. A first fixing tooth 25 is fixedly connected to the surface of the rotating shaft 24. A plugging groove 26 is formed at the top of the rotating shaft 24. A guide rod 27 is fixedly connected to one side of the first fixing plate 21. A pressing plate 28 is lapped on the surface of the guide rod 27. A spring 29 is fixedly connected to one side of the pressing plate 28. One end of the spring 29 away from the pressing plate 28 is fixedly connected to the side of the first fixing plate 21 close to the guide rod 27. A second fixing tooth 210 is fixedly connected to the side of the pressing plate 28 away from the spring 29. The surface of the second fixing tooth 210 meshes with the surface of the first fixing tooth 25. A fixing screw 211 is threadedly connected to the bottom of the rotating shaft 24.

[0026] In this embodiment, during the rotation process, the first fixing tooth 25 on the surface of the rotating shaft 24 pushes the second fixing tooth 210 to move. As a result, while the pressing plate 28 slides along the guide rod 27, the spring 29 is compressed. The rotation of the rotating shaft 24 needs to overcome the pressure of the spring 29 pushing the pressing plate 28 to rotate smoothly. Only relying on the self-weight of the container door 4, the rotating shaft 24 cannot rotate, enabling the container door 4 to maintain an opening angle on an inclined ground, making it more convenient to use. Embodiment 3

[0027] As Figures 1-5 As shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, the hinge plugging part 3 includes a second fixing plate 31. One side of the second fixing plate 31 is lapped with one side of the container door 4. A second bolt 32 is inserted into the second fixing plate 31. One end of the second bolt 32 is threadedly connected to the inside of the container door 4. A rotating arm 33 is fixedly connected to the side of the second fixing plate 31 away from the container door 4. A fixing block 34 is fixedly connected to the bottom of the end of the rotating arm 33 away from the second fixing plate 31. A plugging rod 35 is fixedly connected to the bottom of the fixing block 34. The surface of the plugging rod 35 meshes with the inner wall of the plugging groove 26. The upper end of the fixing screw 211 is threadedly connected to the inside of the end of the plugging rod 35 away from the fixing block 34.

[0028] In this embodiment, the first fixing plate 21 is fixed on the surface of the military container 1 through the first bolt 22. Subsequently, after the second fixing plate 31 is fixed on the surface of the container door 4 through the second bolt 32, the container door 4 is lifted to insert the insertion rod 35 into the insertion slot 26, so that the container door 4 can be preliminarily installed on the military container 1 without manual support by other personnel. Subsequently, the fixing screw 211 is rotated so that the upper end of the fixing screw 211 is threadedly connected to the bottom of the insertion rod 35, and the installation of the hinge can be completed, making its installation more convenient.

[0029] Next, the working principle of the hinge of the military container will be specifically described.

[0030] As Figures 1-5 shown, during installation, first, the first fixing plate 21 is fixed on the surface of the military container 1 through the first bolt 22. Subsequently, after the second fixing plate 31 is fixed on the surface of the container door 4 through the second bolt 32, the container door 4 is lifted to insert the insertion rod 35 into the insertion slot 26, so that the container door 4 can be preliminarily installed on the military container 1 without manual support by other personnel. Subsequently, the fixing screw 211 is rotated so that the upper end of the fixing screw 211 is threadedly connected to the bottom of the insertion rod 35, and the installation of the hinge can be completed, making its installation more convenient. During use, the container door 4 is rotated, and then the rotating arm 33 drives the insertion rod 35 to rotate, causing the rotating shaft 24 to rotate, thereby completing the opening and closing of the bottom container door 4. At the same time, during the rotation process, the first fixed tooth 25 on the surface of the rotating shaft 24 pushes the second fixed tooth 210 to move. Then, while the pressing plate 28 slides along the guide rod 27, the spring 29 is compressed, so that the rotation of the rotating shaft 24 needs to overcome the pressure of the spring 29 pushing the pressing plate 28 to rotate smoothly. Without the gravity of the container door 4 alone, the rotating shaft 24 cannot rotate, enabling the container door 4 to maintain the opening angle on the inclined ground and making it more convenient to use.

[0031] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, any modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
