Description

Technical Field

[0001] The utility model belongs to the technical field of marine containers, and particularly relates to a self-locking structure for container ships that prevents loosening. Background Art

[0002] Containers for ships, also known as marine containers, are standardized large loading containers designed and manufactured specifically for maritime transportation. Such containers play a crucial role in logistics, transportation, and international trade, providing an efficient, safe, and standardized way to transport various goods.

[0003] A Chinese patent with the publication number "CN219383614U" discloses a container with a self-locking device, which includes: a container body with a hollow interior; a cover plate mechanism fixedly installed on the outer surface of one end of the container body; a self-locking mechanism fixedly installed on one side of the outer surface of the cover plate mechanism; a self-locking box body fixedly installed on the outer surface of one side of the first cover plate, and a locking rod fixedly connected inside the self-locking box body; a connecting mechanism fixedly installed on the outer surface of one side of the container body. This new type of container with a self-locking device prevents the phenomenon that when the container is transporting goods and encounters bumpy roads midway, the connection of the door lock shakes and automatically opens. Through the self-locking mechanism, the stability of the door lock connection of the container is facilitated, and thus the objects in the container are prevented from falling out and injuring the staff.

[0004] Although the above device is convenient to operate and use during operation, it uses an electric motor-assisted driving method to open and close the container door. In its specific application process, during the overall use, the driving motor needs an external power supply to drive the self-locking structure. When the container is used on a ship, it needs to be stacked and stacked. Obviously, the external power supply is extremely cumbersome and inconvenient. And even if an external power supply can be connected, during the hoisting and transfer process, the power supply wires and other structures need to be cut off. It can be seen that the method of using an electric motor lock is extremely cumbersome and inconvenient. If the electric motor fails or it is not convenient to connect the power supply, there is also a situation where the door cannot be opened. It can be seen that its overall use is extremely cumbersome and inconvenient, and it needs to be improved. Summary of the Utility Model

[0005] Aiming at the problems mentioned in the background art, the purpose of the present utility model is to provide a self-locking structure for container ships that prevents loosening to solve the problems raised in the background art.

[0006] The above technical purpose of the present utility model is achieved through the following technical solutions:

[0007] A self-locking structure for a container ship to prevent loosening, including a box body. A box door is hinged at the front end of the box body. At the upper and lower ends of one side of the box door away from the hinged part with the box body, clamping rings are fixedly installed. A clamping device is fixedly installed on the front side of the box body near the clamping rings. The front end of the clamping device penetrates through the clamping rings, and the box door is connected to the front opening of the box body through the clamping device.

[0010] As a preferred technical solution, the limiting component includes a sliding frame, which is fixedly connected to the front end of the first spring. The sliding frame is slidably connected inside the movable rail. A second spring is fixedly installed inside the sliding frame. A clamping frame is fixedly installed at the end of the second spring. The inner end of the clamping frame is inserted into the outer end of the clamping mechanism.

[0011] As a preferred technical solution, a vertical shaft is fixedly connected to the outer end of the clamping frame, and a pull ring is fixedly installed at the outer end of the vertical shaft through the sliding frame.

[0012] As a preferred technical solution, the clamping mechanism includes a sliding rod, which is fixedly installed at the front side of the sliding frame.

[0024] Embodiment

[0025] Refer to Figures 1 to 5, A self-locking structure for a container ship to prevent loosening in this embodiment includes a box body 1. A box door 2 is hinged to the front end of the box body 1. At the upper and lower ends of one side of the box door 2 far from the hinged part with the box body 1, clamping rings 4 are fixedly installed. On the front side of the box body 1 close to the clamping rings 4, a clamping device 3 is fixedly installed. The front end of the clamping device 3 penetrates through the clamping ring 4, and the box door 2 is connected to the front-end opening of the box body 1 through the clamping device 3;

[0026] The clamping device 3 includes a movable rail 31. The movable rail 31 is fixedly installed on the front side of the box body 1 close to the clamping ring 4. An elastic mechanism 32 is fixedly installed inside the movable rail 31. The end of the elastic mechanism 32 is fixedly installed with a clamping mechanism 33. The clamping mechanism 33 penetrates through the clamping ring 4 and is clamped to the lower end of the elastic mechanism 32. The front end of the clamping device 3 can penetrate through the clamping ring 4, so that the box door 2 can be tightly connected to the front-end opening of the box body 1 through the clamping device 3. The core part of the clamping device 3 includes a movable rail 31, an elastic mechanism 32 and a clamping mechanism 33. The movable rail 31 is fixed on the front side of the box body 1 close to the clamping ring 4, and an elastic mechanism 32 is installed inside. The end of the elastic mechanism 32 is connected to the clamping mechanism 33. This mechanism can penetrate through the clamping ring 4 and be tightly clamped to the lower end of the clamping ring 4 under the action of the elastic mechanism 32. This design ensures that the box door 2 can be firmly locked on the box body 1 when closed, effectively preventing the box door 2 from loosening during transportation.

[0027] Reference Figures 3 - 5 , The elastic mechanism 32 includes a first spring 321. The first spring 321 is fixedly installed at the rear end inside the movable rail 31. The front end of the first spring 321 is fixedly installed with a limit component 322. The limit component 322 is clamped to the outer end of the clamping mechanism 33, and the front side of the limit component 322 is fixedly connected to the rear end of the clamping mechanism 33. By using the first spring 321 as the elastic mechanism 32, it can provide stable elastic force to ensure that when the box door 2 is closed, the clamping mechanism 33 can be firmly inserted into and clamped to the clamping ring 4. This design not only improves the connection tightness between the box door 2 and the box body 1, but also effectively prevents the box door 2 from loosening due to vibration or other external forces during transportation. Secondly, the setting of the limit component 322 further enhances the stability of the self-locking structure. The limit component 322 is clamped to the outer end of the clamping mechanism 33, and at the same time its front side is fixedly connected to the rear end of the clamping mechanism 33, forming a stable overall structure. This design enables the clamping mechanism 33 to be inserted into the clamping ring 4 more stably when the box door 2 is closed, and through the locking effect of the limit component 322, it prevents the clamping mechanism 33 from accidentally sliding or loosening during transportation.

[0028] Reference Figures 3 - 5, the limiting component 322 includes a sliding frame 3221. The sliding frame 3221 is fixedly connected to the front end of the first spring 321. The sliding frame 3221 is slidably connected to the inside of the movable rail 31. A second spring 3222 is fixedly installed inside the sliding frame 3221. The end of the second spring 3222 is fixedly installed with a clamping frame 3223. The inner end of the clamping frame 3223 is inserted into the outer end of the clamping mechanism 33. The sliding frame 3221 is fixedly connected to the front end of the first spring 321 and slides inside the movable rail 31, ensuring that under the elastic force of the spring, the sliding frame 3221 can move smoothly back and forth. The second spring 3222 is installed inside the sliding frame 3221, and its end is fixed with a clamping frame 3223. When the first spring 321 pushes the sliding frame 3221 forward, the second spring 3222 is compressed accordingly, providing additional elastic force for the clamping frame 3223. When the clamping mechanism 33 passes through the clamping ring 4, the clamping frame 3223 can move inward and be inserted into the outer end of the clamping mechanism 33, realizing stable locking of the clamping mechanism 33. This design not only enhances the reliability of the self-locking structure but also ensures the stability of the box door 2 in the closed state, effectively avoiding the loosening of the box door 2 caused by vibration or other external forces, and further improving the safety of the container.

[0029] Reference Figures 3 - 5 , the outer end of the clamping frame 3223 is fixedly connected with a vertical shaft 3224. The outer end of the vertical shaft 3224 penetrates through the sliding frame 3221 and is fixedly installed with a pull ring 3225. The design of the clamping frame 3223 and the pull ring 3225 further enhances the operation convenience and practicality of the self-locking structure for container ships. The outer end of the clamping frame 3223 is fixedly connected with a vertical shaft 3224. The vertical shaft 3224 passes through the sliding frame 3221 and is fixedly installed with a pull ring 3225. This structure allows the operator to manually control the position of the clamping frame 3223 by pulling the pull ring 3225. When it is necessary to open the box door 2, the operator only needs to gently pull the pull ring 3225, and the clamping frame 3223 can be driven to move outward by the vertical shaft 3224, thus releasing the locking of the clamping frame 3223 on the clamping mechanism 33. This design not only simplifies the operation process, improves work efficiency, but also ensures the accuracy and safety of the operation. In addition, the setting of the pull ring 3225 enables the operator to more intuitively perceive the position and state of the clamping frame 3223, further enhancing the reliability and usability of the self-locking structure.

[0030] Reference Figures 3 - 5The clamping mechanism 33 includes a sliding rod 331, which is fixedly installed on the front side of the sliding frame 3221. The outer end of the sliding rod 331 is hinged with a connecting rod 332, and the outer end of the connecting rod 332 is hinged with a limiting rod 333. The outer end of the limiting rod 333 is provided with a slot 334, and the inner end of the bracket 3223 is inserted into the inside of the slot 334. The end of the sliding rod 331 passes through the clamping ring 4. The clamping mechanism 33 is composed of the sliding rod 331, the connecting rod 332 and the limiting rod 333, which are connected by a hinged manner so that the whole mechanism can move flexibly. The sliding rod 331 is fixedly installed on the front side of the sliding frame 3221. When the sliding frame 3221 moves under the action of the elastic mechanism 32, the sliding rod 331 also moves accordingly, thereby driving the connecting rod 332 and the limiting rod 333 to flip over. The outer end of the limiting rod 333 is provided with a slot 334 When the door 2 is opened, the operator can pull the pull ring 3225 and move the bracket 3223 outward to release the locking cam 333, thereby releasing the locking cam 333 and allowing the door 2 to be opened smoothly.

[0031] refer to Figures 3 - 5 The rear end of the sliding frame 3221 is fixedly installed with a connecting shaft 34, and the inner side of the rear end of the connecting shaft 34 is fixedly connected with an adjusting armrest 35. The adjusting armrest 35 is fixed to the rear end of the sliding frame 3221 through the connecting shaft 34. The user can conveniently operate the movement of the sliding frame 3221 by holding the adjusting armrest 35, and then control the locking and unlocking of the clamping mechanism 33. This design not only simplifies the operation process and reduces the difficulty of operation, but also makes the operation more intuitive and easy to understand. At the same time, the fixed connection method of the adjusting armrest 35 ensures its stability and reliability during operation. As a key component connecting the adjustable armrest 35 and the sliding frame 3221, its solid structure and stable connection mode ensure that the adjustable armrest 35 will not loosen or deflect when subjected to force, thereby ensuring the stability and safety of the entire self-locking structure. In addition, the setting of the adjustable armrest 35 also enables the operator to more flexibly control the locking and unlocking process of the door 2. By operating the adjustable armrest 35, the operator can control the movement of the sliding frame 3221 and the locking state of the clamping mechanism 33 at any time as needed, thereby realizing fast, convenient and reliable locking and unlocking of the door 2.

[0032] refer to Figures 1 - 2A bridge armrest 5 is fixedly connected to the front side of the box door 2 near the clamping ring 4, and the outer surfaces of the bridge armrest 5 and the adjustable armrest 35 are fixedly connected with anti-slip armrest covers. The design of the bridge armrest 5 not only provides a convenient gripping point for the operator, but also enables the operator to maintain a stable posture and balance during operation. This design not only improves the safety and reliability of operation, but also reduces the risk of accidents caused by improper operation. Secondly, the addition of the anti-slip armrest cover further enhances the friction of the armrest surface, preventing the operator from slipping due to sweating or slippery hands during operation, which not only improves the stability and reliability of operation, but also ensures the personal safety of the operator. In addition, the material and design of the anti-slip armrest cover also take into account the comfort of the operator's hands. The soft and breathable material can reduce the discomfort of the operator's hands when holding the armrest for a long time, thereby improving the operator's work efficiency and work experience.

[0033] Principle and advantages of use: By setting the clamping device 3, after the container body 1 is loaded, the first spring 321 inside the movable rail 31 is pulled and contracted by pulling the adjusting handrail 35 and pulling the connecting shaft 34. The first spring 321 contracts and drives the slide bar 331 to move toward the rear side. At this time, the door 2 is closed again. At this time, the first spring 321 is reset and drives the slide bar 331 to slide toward the front side. The slide bar 331 moves forward to prompt the connecting rod 332 and the limit rod 333 to be inserted into the inner side of the clamp ring 4. The box door 2 can be installed on the front side of the box body 1 by means of the limit clamping connection of the limit rod 332 and the limit rod 333. When the box door 2 needs to be opened, the connecting shaft 34 can be pulled out by pulling the adjusting armrest 35 to drive the sliding rod 331 to move backward. When the sliding rod 331 moves backward, the connecting rod 332 and the limit rod 333 can be pulled out from the inside of the clamp ring 4. At this time, the clamp ring 4 loses its limit and the box body 1 can be opened. In the specific application process of the device, the box door 2 can be quickly disassembled and assembled without the need for the electric control structure to be locked and fixed, which can improve the convenience of the overall use of the device.

[0034] By setting the card-loading mechanism 33 to cooperate with the limit component 322, during the use of the device, when the connecting rod 332 and the limit tube are inserted into the inside of the snap ring 4, since the connecting rod 332 and the limit rod 333 are hinged to each other, and the connecting rod 332 and the slide rod 331 are hinged, at this time, it can assist in adjusting the flipping and rotation of the connecting rod 332 and the limit rod 333. When the limit rod 333 and the connecting rod 332 flip and rotate, they can be wrapped around the inner side of the snap ring 4. And a slot 334 is opened at the end of the limit rod 333. During this period, the second spring 3222 resets to drive the card holder 3223 to move inwards. When the card holder 3223 moves inwards, it can be inserted into the inside of the slot 334. The mutual limitation between the card holder 3223 and the slot 334 can lock and fix the limit rod 333, and can limit the limit rod 333. At this time, the limit rod 333, the connecting rod 332 and the snap ring 4 are wrapped and limited, which can further lock and fix the box door 2, so that the whole device can have a stable connection after being locked and fixed, and the phenomenon that the pull ring 3225 loosens can be avoided. It can make the box door 2 have a self-locking performance when closed, and the whole has strong stability.
