Abstract
Description
Technical Field
[0001] This utility model relates to the field of container technology, and in particular to a novel container top cover locking mechanism. Background Technology
[0002] An open-top container is a special type of container whose top can be opened to facilitate the loading of large, heavy, or irregularly shaped goods.
[0003] The top of an open-top container typically consists of an openable roof panel that can be opened and closed via chains or a hydraulic system. When closed, the roof panel, like the rest of the container, ensures the sealing and safety of the cargo. Because the top can be opened, open-top containers are particularly suitable for loading oversized, overheight, or overweight cargo, such as large machinery, steel, and timber. These cargoes are difficult to load through the door of a regular container, but open-top containers allow for direct lifting of cargo from the top by a crane. This is especially convenient for loading and unloading heavy cargo.
[0004] However, in existing container transportation technologies, the locking mechanism of the container top cover is usually manually operated, requiring operators to manually flip and open or close the top cover. This is not only time-consuming but also labor-intensive, especially when the top cover needs to be opened and closed frequently. Furthermore, since traditional locking mechanisms are usually exposed to the outside, criminals can attempt to damage the locking mechanism by hitting or prying it, thereby illegally entering the container. In view of this, a new type of container top cover locking mechanism is provided to overcome the above-mentioned defects. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a novel container top cover locking mechanism.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a novel container top cover locking mechanism, comprising a container body, a top cover body rotatably connected to the rear top of the container body, a fixed shaft fixedly connected to the rear inner side of the container body, a hydraulic rod rotatably connected to the outer front end of the fixed shaft, a sliding piece rotatably connected to the output end of the hydraulic rod, a limit shell slidably connected to the outer side of the sliding piece, a fixed seat fixedly connected to the top of the front front face of the container body, a first locking piece rotatably connected to the top front side of the fixed seat, a second locking piece fixedly connected to the top of the first locking piece, a first locking body fixedly connected to the top front side of the top cover body, and a second locking body fixedly connected to the front top of the top cover body.
[0007] As a further description of the above technical solution: the top of the limiting shell is fixedly connected to the lower end face of the top cover body, the inner side of the first locking plate engages with the outer side of the first lock body, and the inner side of the second locking plate engages with the outer side of the second lock body, which can restrict the top cover body. The opening method is changed from manual flipping to remote control opening. The hydraulic rod is set inside the box body, making it difficult for criminals to damage the hydraulic rod by hitting or prying, thus improving the overall security of the box body to a certain extent.
[0008] As a further description of the above technical solution: there are two hydraulic rods and two limiting shells. The hydraulic rods are distributed on the left and right sides above the rear end of the box body, and the limiting shells are distributed on the left and right sides at the bottom of the top cover body. The hydraulic rods and the limiting shells are parallel to each other. The opening and closing of the top cover body is achieved by extending and retracting the hydraulic rods.
[0009] As a further description of the above technical solution: a groove is provided on the inner side of the limiting shell from front to back, and the longitudinal cross-sectional shape of the groove on the inner side of the limiting shell matches the longitudinal cross-sectional shape of the sliding piece, so that the sliding piece at the top of the front side of the hydraulic rod can slide inside the limiting shell.
[0010] As a further description of the above technical solution: the bottom of the limiting shell is provided with a sliding groove from front to back, and the width of the sliding groove matches the cross-sectional diameter of the hydraulic rod output end. The groove opened on the inner side of the limiting shell is interconnected with the sliding groove opened on the bottom of the limiting shell, and the sliding plate inside the limiting shell can be driven to move by the hydraulic rod on the outer side of the bottom of the limiting shell.
[0011] As a further description of the above technical solution: the longitudinal cross-section of the first lock body is convex, and a first lock groove is provided in the middle rear of the first lock plate. The length and width of the cross-section of the top of the first lock body correspond to the first lock groove provided in the middle rear of the first lock plate. The first lock plate can rotate 90° from top to back with the front top of the fixed seat as the base point. This can restrict the top cover body when the box is transported, and prevent the hydraulic rod connecting the box and the top cover body from loosening due to vibration during the transportation of the box.
[0012] As a further description of the above technical solution: a second locking groove is provided in the middle of the second locking plate, and the length and width of the cross section of the top of the second lock body correspond to the second locking groove provided in the middle of the second locking plate, which has the same function as the first locking plate and the first lock body, and improves the service life of the hydraulic rod to a certain extent.
[0013] This utility model has the following beneficial effects:
[0014] This utility model introduces a novel container top cover locking mechanism. Through the design and cooperation of a hydraulic rod and a sliding plate, the device can restrict the top cover body, changing the opening method from manual flipping to remote control. The hydraulic rod is located inside the container, making it difficult for criminals to damage it through striking or prying, thus improving the overall security of the container. A first lock body and a second lock body are located at the top front of the top cover body, corresponding to the first and second lock plates on the front of the container. The first lock plate is locked outside the first lock body, and the second lock plate is locked outside the second lock body. This restricts the top cover body during container transportation, preventing the hydraulic rod connecting the container and the top cover body from loosening due to vibration during transport, thus extending the service life of the hydraulic rod.

[0021] Reference Figures 1 to 4This utility model provides a novel container top cover locking mechanism, comprising a container body 1, a top cover body 2 connected to the rear of the top of the container body 1 via a hinge, a fixed shaft 3 disposed on the rear inner side of the container body 1, a hydraulic rod 4 disposed on the outer side of the front end of the fixed shaft 3, a rotatable sliding piece 6 disposed at the output end of the hydraulic rod 4, the outer side of the sliding piece 6 being inserted into the interior of the limiting shell 5 and sliding, a fixed seat 7 welded to the top of the front face of the container body 1, a rotatable first locking piece 8 disposed on the top front side of the fixed seat 7, a second locking piece 9 welded to the top of the first locking piece 8, and a second locking piece 9 welded to the top front side of the top cover body 2. The first lock body 10 and the second lock body 11 are welded to the front top of the top cover body 2. The top of the limiting shell 5 is fixedly connected to the lower end face of the top cover body 2. The inner side of the first lock plate 8 engages with the outer side of the first lock body 10, and the inner side of the second lock plate 9 engages with the outer side of the second lock body 11. This can restrict the top cover body 2. The opening method is changed from manual flipping to remote control opening. The hydraulic rod 4 is set inside the box 1. It is difficult for criminals to damage the hydraulic rod 4 by hitting or prying, which improves the overall security of the box 1 to a certain extent.
[0022] As a further implementation of the above technical solution: there are two hydraulic rods 4 and two limiting shells 5. The hydraulic rods 4 are distributed on the left and right sides above the rear end of the inner side of the box body 1, and the limiting shells 5 are distributed on the left and right sides at the bottom of the top cover body 2. The hydraulic rods 4 and the limiting shells 5 are parallel to each other. The opening and closing of the top cover body 2 is achieved by extending and retracting the hydraulic rods 4.
[0023] As a further implementation of the above technical solution: a groove is provided on the inner side of the limiting shell 5 from front to back, and the longitudinal cross-sectional shape of the groove on the inner side of the limiting shell 5 matches the longitudinal cross-sectional shape of the sliding piece 6, so that the sliding piece 6 at the front top of the hydraulic rod 4 can slide inside the limiting shell 5.
[0024] As a further implementation of the above technical solution: a sliding groove is provided at the bottom of the limiting shell 5 from front to back, and the width of the sliding groove matches the cross-sectional diameter of the output end of the hydraulic rod 4. The groove opened on the inner side of the limiting shell 5 is interconnected with the sliding groove opened at the bottom of the limiting shell 5, and the sliding piece 6 inside the limiting shell 5 can be driven to move by the hydraulic rod 4 on the outer side of the bottom of the limiting shell 5.
[0025] As a further implementation of the above technical solution: the longitudinal cross-section of the first lock body 10 is convex, and the first lock plate 8 has a first lock groove in the middle rear. The length and width of the cross-section of the top of the first lock body 10 correspond to the first lock groove in the middle rear of the first lock plate 8. The first lock plate 8 can rotate 90° from top to back with the front top of the fixed seat 7 as the base point. When the box 1 is transported, it can restrict the top cover body 2 and prevent the hydraulic rod 4 connecting the box 1 and the top cover body 2 from loosening due to vibration during the transportation of the box 1.
[0026] As a further implementation of the above technical solution: a second locking groove is provided in the middle of the second locking plate 9, and the length and width of the cross section of the top of the second lock body 11 correspond to the second locking groove provided in the middle of the second locking plate 9. The function is the same as that of the first locking plate 8 and the first lock body 10, which improves the service life of the hydraulic rod 4 to a certain extent.
[0027] Working principle:
[0028] When using this utility model, the goods are placed into the box 1 from the top. After placement, the top cover body 2 is closed. The hydraulic rod 4 located inside the rear of the box 1 is activated. The hydraulic rod 4 drives the sliding piece 6 at the output end to retract. At this time, the sliding piece 6 slides from front to back inside the limiting shell 5. The bottom of the hydraulic rod 4 also changes angle under the restriction of the fixed shaft 3 until the top cover body 2 and the top of the box 1 are closed. Then the hydraulic rod 4 is closed. The operator moves the first locking piece 8 and the second locking piece 9 backward. The first locking piece 8 and the second locking piece 9 rotate backward with the front top of the fixed seat 7 as the base point until the first locking piece 8 is fitted on the outside of the first lock body 10 and the second locking piece 9 is fitted on the outside of the second lock body 11. Both sets are in contact and locked. When the box 1 is being transported, the top cover body 2 can be restricted, and the connection of the hydraulic rod 4 between the box 1 and the top cover body 2 can be prevented from becoming loose due to vibration during the transportation of the box 1. This improves the service life of the hydraulic rod 4 to a certain extent.
[0029] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
