Description

Technical Field

[0001] This application relates to the field of container hinge technology, and more specifically, to a combination container hinge with locking function. Background Technology

[0002] A container is a modular tool that can carry packaged or unpackaged goods for transport and is easy to load and unload using mechanical equipment. Containers play a very important role in the transportation of goods. They enable the standardization of a massive object weighing tens of tons, and on this basis, a multimodal transport system integrating ships, ports, shipping routes, highways, transit stations, bridges, and tunnels can be gradually realized on a global scale. This allows the establishment of a standardized, systematic, and large-scale transportation system. When in use, a container is usually composed of a container body and container doors, and the container body and container doors are mostly connected by hinge plates. The container hinge plates are an important part of the overall container.

[0003] Existing container hinges, due to their inherent flexibility, can cause the container door to swing during loading and unloading, affecting the loading and unloading process and making it inconvenient to lock the door to the container during loading and unloading.

[0004] To address the aforementioned issues, this application provides a combined container hinge with a locking function. Utility Model Content

[0005] The technical solution for a combined container hinge with locking function provided in this application is as follows:

[0006] A modular container hinge with locking function includes a first hinge plate, a second hinge plate on one side of the first hinge plate, an engaging assembly between the first and second hinge plates, a first positioning hole evenly distributed through one side of the first hinge plate, a limit block fixedly connected to the inner side of the first hinge plate, a first slot formed at the upper end of the first hinge plate, an L-shaped plate fixedly connected to the upper end of the first hinge plate, a second positioning hole evenly distributed through one side of the second hinge plate, a second slot formed at the upper end of the second hinge plate, an extension block fixedly connected to the inner side of the second hinge plate, and the engaging assembly includes a vertical rod passing through the upper end of the L-shaped plate, a baffle plate fixedly connected to the upper end of the vertical rod, a locking block fixedly connected to the lower end of the vertical rod, and a through groove formed at the upper end of one side of the locking block.

[0007] Furthermore, the upper end of the limiting block is provided with a rotating groove, and the upper end of the L-shaped plate is provided with a through moving groove.

[0008] Through the above technical solution, the rotating groove is used to place the rotating rod and to limit the rotating rod to prevent it from leaving the rotating groove, that is, to restrict the extension block between the limiting blocks.

[0009] Furthermore, a circular groove is formed on the inner wall of the bottom side of the first slot, the circular groove is connected to the through groove, and a locking rod is connected to the outside of the circular groove.

[0010] With the above technical solution, the first slot is used to place the card block, and the existence of the circular groove and the through groove facilitates the passage of the external card rod. The external card rod is used to limit the card block on the first slot and prevent the card block from moving accidentally on the first slot.

[0011] Furthermore, a third slot is provided on the inner wall of the other side of the bottom of the first slot, and the third slot is connected to the second slot.

[0012] The above technical solution enables the third card slot to be connected to the second card slot, and allows the third card slot and the second card slot to be connected as a whole to hold the card block.

[0013] Furthermore, both ends of the extension block are fixedly connected to rotating rods, which are rotatably connected to rotating grooves. The vertical rod passes through the interior of the movable groove. The baffle is located above the L-shaped plate. The locking block is slidably engaged with the first locking groove. The locking block is also slidably engaged with the combination groove of the third locking groove and the second locking groove.

[0014] With the above technical solution, the baffle is used to restrict the vertical rod in the moving groove, and the vertical rod moves along the moving groove to drive the locking block to move along the first locking groove.

[0015] In summary, this application includes the following beneficial technical effects:

[0016] This application can lock the first hinge plate and the second hinge plate to prevent the container door from swinging when the container is opened for loading and unloading. The external locking rod places the locking block in the first locking slot to prevent the locking block from affecting the normal opening and closing operation of the first hinge plate and the second hinge plate when it is not needed. By placing the locking block in the combination slot of the third locking slot and the second locking slot, the first hinge plate and the second hinge plate are limited to form a lock.

[0026] Example:

[0027] This application discloses a combined container hinge with a locking function. Please refer to [link / reference]. Figures 1-4The assembly includes a first hinge plate 1, a second hinge plate 2 on one side of the first hinge plate 1, a locking assembly 3 between the first hinge plate 1 and the second hinge plate 2, a first positioning hole 11 evenly extending through one side of the first hinge plate 1, a limit block 12 fixedly connected to the inner side of the first hinge plate 1, a first slot 13 at the upper end of the first hinge plate 1, an L-shaped plate 14 fixedly connected to the upper end of the first hinge plate 1, a second positioning hole 21 evenly extending through one side of the second hinge plate 2, a second slot 22 at the upper end of the second hinge plate 2, an extension block 23 fixedly connected to the inner side of the second hinge plate 2, and a vertical rod 31 extending through the upper end of the L-shaped plate 14. A baffle 32 is fixedly connected to the upper end of the vertical rod 31, and a locking block 33 is fixedly connected to the lower end of the vertical rod 31. A through groove 34 is extending through the upper end of one side of the locking block 33.

[0028] The upper end of the limiting block 12 is provided with a rotating groove 121, and the upper end of the L-shaped plate 14 is provided with a moving groove 141.

[0029] The slot 121 is used to place the rotating rod 231 and to limit the rotating rod 231 to prevent it from falling out of the slot 121, that is, to restrict the extension block 23 between the limiting blocks 12.

[0030] A circular groove 131 is provided on the inner wall of the bottom side of the first slot 13. The circular groove 131 is connected to the through groove 34, and a locking rod is connected to the outside of the circular groove 131.

[0031] The first slot 13 is used to place the card block 33. The existence of the circular groove 131 and the through groove 34 facilitates the passage of the external card rod. The external card rod is used to limit the card block 33 on the first slot 13 to prevent the card block 33 from moving accidentally on the first slot 13.

[0032] A third slot 132 is provided on the inner wall of the other side of the bottom of the first slot 13, and the third slot 132 is connected to the second slot 22.

[0033] The third card slot 132 is connected to the second card slot 22, so that the third card slot 132 and the second card slot 22 can be connected into a whole to place the card block 33.

[0034] Both ends of the extension block 23 are fixedly connected to rotating rods 231, which are rotatably connected to rotating grooves 121. The vertical rod 31 passes through the interior of the moving groove 141. The baffle 32 is located above the L-shaped plate 14. The locking block 33 is slidably engaged with the first locking groove 13. The locking block 33 is also slidably engaged with the combination groove of the third locking groove 132 and the second locking groove 22.

[0035] The baffle 32 is used to restrict the vertical rod 31 in the moving groove 141. The vertical rod 31 moves along the moving groove 141 to drive the locking block 33 to move along the first locking groove 13.

[0036] The implementation principle of this embodiment is as follows: When it is necessary to lock the opened first hinge plate 1 and second hinge plate 2, that is, after the first hinge plate 1 and second hinge plate 2 are opened to a flush position, the operator first removes the external locking rod from the inside of the circular groove 131 and the through groove 34. Then, the moving baffle 32 drives the vertical rod 31 to move along the moving groove 141. At this time, the vertical rod 31 will drive the locking block 33 to move along the first locking groove 13. After the vertical rod 31 is moved to the inner edge of the moving groove 141, the locking block 33 and... When the first slot 13 is separated, the baffle 32 can be pushed down to push the locking block 33 along the combination groove of the third slot 132 and the second slot 22 via the vertical rod 31 until the bottom of the locking block 33 is in contact with the combination groove of the third slot 132 and the second slot 22. At this time, the locking block 33 can prevent the first hinge plate 1 and the second hinge plate 2 from rotating again, that is, it effectively locks the first hinge plate 1 and the second hinge plate 2, thereby preventing the container door from swinging when the container is opened for loading and unloading.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
