Description

Technical Field

[0001] This utility model relates to the field of container technology, specifically to a container lashing twist lock. Background Technology

[0002] A container lashing twist lock is a device used to secure containers, primarily for connecting and locking containers on different decks or between the bottom container and its base. This prevents containers from tipping over or sliding during transport. The twist lock typically has a mushroom-shaped end. To use it, it is first inserted into the bottom hole of the container corner fitting, and then rotated 90 degrees using a handle or automatic device to lock it in place. The twist lock design must meet the following safety requirements: it must be able to lock automatically and have simple front and back markings; it must not separate from the corner fitting even with slight surface rubbing; the locked and unlocked states should be easily identifiable, and it should not automatically relock due to vibration. Twist locks are crucial safety equipment in container transport, and their proper use effectively ensures the stability of goods during transit.

[0003] Extensive research revealed problems with existing container lashing twist locks. During nighttime operations, insufficient lighting may prevent operators from clearly seeing if the twist lock is fully inserted into the corner fittings or from rotating it correctly to the locking position. For example, some twist locks require a 90-degree rotation to lock, but the operator may only rotate it 45 degrees, resulting in insufficient locking force and posing a risk of container collapse, thus affecting operator use. Therefore, based on the aforementioned research and existing technologies, a new container lashing twist lock is proposed to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a container lashing twist lock to solve the problems mentioned in the background art.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] In one typical implementation of this application, please refer to Figures 1-4 A container lashing twist lock includes a twist lock body 1, which includes a lock body 2, a handle 3, a mounting shaft 4, and a locking tongue 5. The mounting shaft 4 is rotatably connected inside the lock body 2, and the locking tongue 5 for locking the container is fixedly installed on the top surface of the mounting shaft 4. The handle 3 for unlocking is rotatably connected to one side of the lock body 2, and a locking structure 6 is provided on both sides of the lock body 2 for locking the locking tongue 5.

[0022] The latch 5 includes two support frames 9, both of which are fixedly installed on both sides of the lock body 2. A support cylinder 20 is fixedly installed on the inner bottom surface of each support frame 9. A locking pin 19 is slidably connected inside the support cylinder 20. The upper end of the locking pin 19 passes through the support frame 9 and extends to the outside of the support frame 9. Fixing blocks 7 are fixedly installed on both sides of the latch 5. A fixing hole 8 is opened on the top surface of the fixing block 7. The outer circular wall surface of the locking pin 19 is movably engaged with the inner circular wall surface of the fixing hole 8. A connecting rod 23 is fixedly installed on the bottom surface of the locking pin 19, and the connecting rod 23 passes through the support... The support cylinder 20 extends to the outside of the support cylinder 20. A spring 24 is sleeved on the outer circular wall of the connecting rod 23. The spring 24 provides the force required for the reset of the locking post 19. One end of the spring 24 is fixedly connected to the bottom surface of the locking post 19, and the other end of the spring 24 is fixedly connected to the inner bottom surface of the support cylinder 20. A rope 14 is fixedly installed on the bottom surface of the connecting rod 23. A connecting plate 10 is fixedly installed on one end of the two ropes 14. A handle 11 is fixedly installed on one side of the connecting plate 10. Reversing components for changing the direction of the ropes 14 are provided on both sides of the lock body 2.

[0023] When locking the container using the twist lock body 1, turning the handle 3 causes the locking tongue 5 to rotate 90 degrees, which in turn causes the fixing block 7 to rotate 90 degrees. The rotation of the locking tongue 5 90 degrees will press the locking pin 19, which causes the locking pin 19 to move downward with the cooperation of the connecting rod 23 and the spring 24. When the fixing block 7 on the side of the locking tongue 5 rotates to above the locking pin 19, the force of the spring 24 causes the locking pin 19 to engage with the fixing block 7, further locking the locking tongue 5 and preventing the twist lock body 1 from not being locked.

[0024] Preferably, when locking stacked containers using the twist lock body 1, the operator turns the handle 3 to rotate the locking tongue 5 and the fixing block 7 by 90 degrees. The rotation of the fixing block 7 will squeeze the locking post 19, which will cause the locking post 19 to move the connecting rod 23 downward on the support cylinder 20 and compress the spring 24. When the fixing block 7 rotates to the top of the locking post 19, the force of the spring 24 will cause the locking post 19 to move upward and enter the fixing hole 8 on the fixing block 7, thereby locking the locking tongue 5 and preventing the locking tongue 5 from not locking due to improper operation.

[0025] On the other hand, during the unlocking process of the twist lock body 1, the operator moves the connecting plate 10 outward. The outward movement of the connecting plate 10 drives the rope 14 outward. Under the action of the reversing component, the rope 14 drives the connecting rod 23 downward. The downward movement of the connecting rod 23 inside the support cylinder 20 compresses the spring 24. The downward movement of the connecting rod 23 drives the locking pin 19 downward to the outside of the fixing hole 8 on the fixing block 7. At this time, the locking tongue 5 can be rotated and unlocked by turning the handle 3, thus preventing the twist lock body 1 from being accidentally unlocked due to vibration. Compared with the existing technology, this method not only ensures that the twist lock body 1 is locked in place but also prevents the twist lock body 1 from being accidentally unlocked, achieving a locking effect on the twist lock body 1. It is highly safe and helps to lock containers using the twist lock body 1.

[0026] The reversing component includes two support rods 15, which are fixedly installed on both sides of the lock body 2. The outer circular wall of the support rod 15 is rotatably connected to a roller 16 through a bearing. The roller 16 can change the direction of movement of the rope 14.

[0027] Preferably, the rope 14 is provided, and the outward movement of the rope 14 drives the roller 16 to rotate around the support rod 15, which changes the direction of movement of the rope 14 from outward to downward, thus achieving the effect of changing the direction of the rope 14.

[0028] Two limiting holes 21 are provided on the outer circular wall of the support cylinder 20. Two limiting blocks 22 are fixedly installed on the outer circular wall of the snap-fit ​​post 19. The limiting blocks 22 are slidably connected to the limiting holes 21. The movement of the snap-fit ​​post 19 can be limited by the cooperation of the limiting blocks 22 and the limiting holes 21.

[0029] Preferably, the locking post 19 is provided. When the locking post 19 moves inside the support cylinder 20, it will cause the limiting block 22 to move inside the limiting hole 21 on the support cylinder 20. The limiting block 22 and the limiting hole 21 cooperate to limit the movement of the locking post 19, thereby achieving the limiting effect of locking post 19.

[0030] Support blocks 17 are fixedly installed on both sides of the lock body 2. A support ring 18 is fixedly installed on one side of the support block 17. The outer circular wall of the rope 14 is slidably connected to the inner circular wall of the support ring 18. The rope 14 can be guided by the cooperation of the support blocks 17 and the support ring 18.

[0031] Preferably, the second support block 17 can support the support ring 18. When the rope 14 moves outward, it will move inside the support ring 18. The support ring 18 can guide the movement of the rope 14, thus achieving the guiding effect of the rope 14.

[0032] Two slide rails 13 are fixedly installed on one side of the lock body 2, and two support blocks 12 are fixedly installed on the top surface of the connecting plate 10. The support blocks 12 are slidably connected to the slide rails 13. The movement of the connecting plate 10 can be restricted by the cooperation of the support blocks 12 and the slide rails 13.

[0033] Preferably, the connecting plate 10 moves outward, causing the support block 12 to move along the slide rail 13. The support block 12 and the slide rail 13 cooperate to restrict the movement of the connecting plate 10 and improve the stability of the movement of the connecting plate 10.

[0034] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
