Description

Technical Field

[0001] This utility model belongs to the field of container quick connection technology, and in particular relates to a container quick connection device. Background Technology

[0002] Container quick-connect devices, also known as container twist locks, are devices used to achieve quick and convenient connection of containers. They are mainly used in scenarios such as container stacking, splicing, and fixing during transportation, which can improve operational efficiency and enhance the stability and security of container connections.

[0003] Traditional container twist locks rely on levers to lock and unlock. If the lever is accidentally touched, the twist lock may turn and unlock. In shipping scenarios, such misoperation may cause the container connection to loosen. Especially when encountering wind, waves, or ship pitching, the loose container may shift, tip over, or even fall into the sea, ultimately causing serious consequences such as cargo loss and marine pollution.

[0004] To solve this problem, some container twist locks will add an anti-accidental activation mechanism to the pull rod. These mechanisms mostly use spring force to lock the pull rod: when the twist lock is in the locked state, the spring applies tension to fix the pull rod in a specific position, and an external force is required to overcome the spring force in order to pull the pull rod to unlock it.

[0005] However, this type of anti-accidental contact mechanism still has obvious defects. Because the spring is in use for a long time and is prone to severe wear in the high-salt and high-humidity marine environment, the spring tension will gradually decrease as the wear intensifies. When the tension is insufficient, even with the protection of this mechanism, if the lever is accidentally touched, it may still drive the torsion lock to rotate, causing the original locking state to fail and failing to completely avoid safety risks. In view of this, we propose a quick connection device for containers. Utility Model Content

[0006] The purpose of this invention is to provide a quick connection device for containers to solve the problems mentioned in the background art.

[0007] In view of this, the present invention provides a quick connection device for containers, including a lock body and a lock cylinder, wherein the lock cylinder is disposed in the lock body, and further includes: A pull rod is fixedly connected to the periphery of the lock cylinder. The pull rod has two first sliding grooves that communicate with the inner cavity of the lock body. A first pressing block is slidably connected in each of the two first sliding grooves. The second slide groove is opened inside the pull rod and is connected to the two first slide grooves. A second extrusion block is slidably connected inside the second slide groove, and the upper and lower sides of one end of the second extrusion block are respectively attached to the two first extrusion blocks. A drive assembly, located within the pull rod, is used to move the second extrusion block.

[0008] In this technical solution, it is ensured that the pull rod will not be affected by external factors and will not rotate.

[0009] In the above technical solution, the driving component further includes: A one-way threaded rod, which is threadedly connected inside the second extrusion block; The first rotating groove is formed at one end of the pull rod and communicates with the second sliding groove. A first rotating rod is rotatably connected in the first rotating groove, and one end of the first rotating rod extends into the second sliding groove and is fixedly connected to one end of the one-way threaded rod. The other end of the first rotating rod extends to the outside. A fixing component, located inside the first rotating rod, is used to fix the first rotating rod. An extrusion groove is formed on the inner wall of the first rotating groove.

[0010] In this technical solution, it is ensured that the user can move the second extrusion block along the second slide.

[0011] In the above technical solution, the fixing component further includes: A limiting groove is formed inside the first rotating rod and communicates with the extrusion groove. Two sliders are slidably connected inside the limiting groove, and the two ends of the two sliders extend into the extrusion groove. Two third extrusion blocks are fixedly connected between the two ends of the two sliders, and a bidirectional threaded rod is threaded between the two sliders. The second rotating groove is formed at one end of the first rotating rod and communicates with the limiting groove. A second rotating rod is rotatably connected in the second rotating groove, and one end of the second rotating rod extends into the limiting groove and is fixedly connected to one end of the bidirectional threaded rod.

[0012] In this technical solution, the first rotating rod is ensured to rotate without being affected by external factors, thereby further improving the stability of the overall device.

[0013] In the above technical solution, further, the two third extrusion blocks are located in the extrusion groove and are slidably connected to the extrusion groove, the two ends of the two sliders are slidably connected to the extrusion groove, and one end of the second rotating rod is rotatably connected to the limiting groove.

[0014] In this technical solution, it is ensured that when the two third extrusion blocks slide, the two third extrusion blocks can slide normally in the extrusion groove, and it is also ensured that when the two sliders slide, both ends of the two sliders can slide normally in the extrusion groove. At the same time, it is ensured that when the second rotating rod rotates, one end of the second rotating rod can rotate normally in the limiting groove.

[0015] In the above technical solution, furthermore, the other end of the second rotating rod is provided with anti-slip texture, and the two sections of thread on the bidirectional threaded rod have opposite directions of rotation and the same thread pitch.

[0016] In this technical solution, because the other end of the second rotating rod is provided with anti-slip texture, when the user rotates the other end of the second rotating rod by hand, the anti-slip texture can increase the friction between the user's hand and the other end of the second rotating rod. At the same time, because the two sections of threads on the bidirectional threaded rod have opposite directions of rotation and the same thread pitch, when the bidirectional threaded rod rotates, the two sliders will be affected by the two sections of threads with opposite directions of rotation on the bidirectional threaded rod, and will move closer to each other by the same distance or further away from each other by the same distance along the limiting groove.

[0017] In the above technical solution, one end of the first rotating rod is rotatably connected to the second sliding groove, and the other end of the first rotating rod is provided with anti-slip texture on its periphery. The one-way threaded rod is located in the second sliding groove and is rotatably connected to the second sliding groove.

[0018] In this technical solution, it is ensured that when the first rotating rod rotates, one end of the first rotating rod can rotate normally within the second sliding groove. Furthermore, because the other end of the first rotating rod is provided with anti-slip texture, when the user rotates the other end of the first rotating rod by hand, the anti-slip texture can increase the friction between the user's hand and the other end of the first rotating rod. At the same time, it is ensured that when the one-way threaded rod rotates, the one-way threaded rod can rotate normally within the second sliding groove.

[0019] In the above technical solution, the pull rod is rotatably connected to the lock body, the two first pressing blocks are located in the inner cavity of the lock body, and the upper and lower sides of one end of the second pressing block are inclined.

[0020] In this technical solution, it is ensured that when the user pulls the lever by hand, the lever can rotate normally in the inner cavity of the lock body, and that when the two first pressing blocks move, the two first pressing blocks can enter the inner cavity of the lock body. At the same time, because the upper and lower sides of one end of the second pressing block are inclined, when one end of the second pressing block presses the two first pressing blocks, the two first pressing blocks can move away from each other.

[0021] The beneficial effects of this utility model are: 1. This container quick-connect device, through the setting of a second slide groove, a second pressing block, a one-way threaded rod, a first rotating groove, and a first rotating rod, allows the user to control the second pressing block to move along the second slide groove. Through the setting of the first slide groove and the first pressing block, when the second pressing block moves, the two first pressing blocks can move away from each other, allowing them to press against the inner wall of the lock body, fixing the pull rod and lock cylinder inside the lock body and preventing them from rotating. The design of this structure fundamentally eliminates problems such as abnormal release of the twist lock locking state and functional failure caused by accidental contact of the pull rod, completely eliminating potential safety hazards during the use of the twist lock, further improving the reliability of the product in actual application scenarios, and allowing users to use it with greater peace of mind and confidence without worrying about safety risks caused by misoperation.

[0022] 2. This container quick-connect device, through the setting of a limiting groove, slider, third pressing block, bidirectional threaded rod, second rotating groove, second rotating rod, and pressing groove, allows two third pressing blocks to move away from or close to each other. When the two third pressing blocks move away from each other to a suitable position, they will press against the inner wall of the pressing groove, fixing the first rotating rod in the first rotating groove and preventing it from rotating. The above structure design can stably fix the first rotating rod in the first rotating groove and prevent it from rotating due to external influences, thus preventing the rod from being fixed and further improving the stability of the rod against accidental contact.

[0030] Example 1: Please see Figure 1 - Figure 5 As shown, this embodiment provides a quick-connect device for containers, including a lock body 1 and a lock cylinder 2, wherein the lock cylinder 2 is disposed within the lock body 1, and further includes: Pull rod 3 is fixedly connected to the periphery of lock cylinder 2. Two first sliding grooves 4 are opened in the pull rod 3 and communicate with the inner cavity of lock body 1. A first pressing block 5 is slidably connected in both first sliding grooves 4. The second slide groove 6 is opened inside the pull rod 3 and is connected to the two first slide grooves 4. The second extrusion block 7 is slidably connected inside the second slide groove 6, and the upper and lower sides of one end of the second extrusion block 7 are respectively attached to the two first extrusion blocks 5. The drive assembly is located inside the pull rod 3 and is used to move the second extrusion block 7.

[0031] In operation, the user pulls the lever 3, causing the lock cylinder 2 to rotate within the lock body 1, ensuring the device functions correctly. When the lever 3 rotates to the appropriate position, the user drives the second pressing block 7 along the second slide groove 6 via the drive assembly. This causes one end of the second pressing block 7 to press against the two first pressing blocks 5, resulting in the upper and lower sides of one end of the second pressing block 7 pressing against the two first pressing blocks 5 respectively. This causes the two first pressing blocks 5 to move away from each other along the two first slide grooves 4. When the two first pressing blocks 5 move away from each other, one end of the two first pressing blocks 5 will press against the inner wall of the lock body 1, fixing the lever 3 within the inner cavity of the lock body 1 and preventing it from rotating. This ensures that the lever 3 will not be affected by external factors and will not rotate.

[0032] Example 2: This embodiment provides a container quick connection device, which, in addition to the technical solutions of the above embodiments, also has the following technical features, and the driving component includes: One-way threaded rod 8, the one-way threaded rod 8 is threadedly connected inside the second extrusion block 7; The first rotating groove 9 is opened at one end of the pull rod 3 and is connected to the second sliding groove 6. The first rotating rod 10 is rotatably connected in the first rotating groove 9, and one end of the first rotating rod 10 extends into the second sliding groove 6 and is fixedly connected to one end of the one-way threaded rod 8. The other end of the first rotating rod 10 extends to the outside. A fixing component is located inside the first rotating rod 10 and is used to fix the first rotating rod 10. The extrusion groove 17 is formed on the inner wall of the first rotating groove 9.

[0033] In use, the user manually rotates the first rotating rod 10, causing one end of the first rotating rod 10 to drive the one-way threaded rod 8 to rotate inside the second extrusion block 7. This causes the second extrusion block 7 to move along the second slide groove 6 under the action of the thread of the one-way threaded rod 8, ensuring that the user can drive the second extrusion block 7 to move along the second slide groove 6.

[0034] Example 3: This embodiment provides a container quick connection device, which, in addition to the technical solutions of the above embodiments, also has the following technical features, including a fixing component: The limiting groove 11 is opened in the first rotating rod 10 and is connected to the extrusion groove 17. Two sliders 12 are slidably connected in the limiting groove 11, and the two ends of the two sliders 12 extend into the extrusion groove 17. Two third extrusion blocks 13 are fixedly connected between the two ends of the two sliders 12. A bidirectional threaded rod 14 is threadedly connected between the two sliders 12. The second rotating groove 15 is formed at one end of the first rotating rod 10 and is connected to the limiting groove 11. A second rotating rod 16 is rotatably connected in the second rotating groove 15, and one end of the second rotating rod 16 extends into the limiting groove 11 and is fixedly connected to one end of the bidirectional threaded rod 14.

[0035] In operation, the user manually rotates the second rotating rod 16, causing one end of the second rotating rod 16 to drive the bidirectional threaded rod 14 to rotate within the limiting groove 11. This causes the two sliders 12 to be acted upon by the two sections of oppositely oriented threads on the bidirectional threaded rod 14, moving them closer or further apart along the limiting groove 11. Consequently, the two limiting grooves 11 respectively drive the two third pressing blocks 13 to move closer or further apart within the pressing groove 17. When the two third pressing blocks 13 move further apart to a position where they cannot move, they will be tightly pressed against the inner wall of the pressing groove 17, fixing the first rotating rod 10 within the first rotating groove 9 and preventing it from rotating. This ensures that the first rotating rod 10 will not be affected by external factors and further improves the stability of the overall device.

[0036] Example 4: This embodiment provides a container quick connection device, which, in addition to the technical solution of the above embodiment, also has the following technical features: two third extrusion blocks 13 are located in the extrusion groove 17 and are slidably connected to the extrusion groove 17; the two ends of the two sliders 12 are slidably connected to the extrusion groove 17; and one end of the second rotating rod 16 is rotatably connected to the limiting groove 11.

[0037] Specifically, it is ensured that when the two third extrusion blocks 13 slide, the two third extrusion blocks 13 can slide normally within the extrusion groove 17, and that when the two sliders 12 slide, both ends of the two sliders 12 can slide normally within the extrusion groove 17. At the same time, it is ensured that when the second rotating rod 16 rotates, one end of the second rotating rod 16 can rotate normally within the limiting groove 11.

[0038] Example 5: This embodiment provides a container quick connection device, which, in addition to the technical solution of the above embodiment, also has the following technical features: the other end of the second rotating rod 16 is provided with anti-slip texture, and the two sections of threads on the bidirectional threaded rod 14 have opposite directions of rotation and the same thread pitch.

[0039] Because the other end of the second rotating rod 16 is provided with anti-slip texture, when the user rotates the other end of the second rotating rod 16 by hand, the anti-slip texture can increase the friction between the user's hand and the other end of the second rotating rod 16. At the same time, because the two sections of threads on the bidirectional threaded rod 14 have opposite directions of rotation and the same thread pitch, when the bidirectional threaded rod 14 rotates, the two sliders 12 will be affected by the two sections of threads with opposite directions of rotation on the bidirectional threaded rod 14, and will move closer to each other by the same distance or further away from each other by the same distance along the limiting groove 11.

[0040] Example 6: This embodiment provides a container quick connection device, which, in addition to the technical solution of the above embodiment, also has the following technical features: one end of the first rotating rod 10 is rotatably connected to the second slide groove 6, the other end of the first rotating rod 10 is provided with anti-slip texture on its periphery, and the one-way threaded rod 8 is located in the second slide groove 6 and is rotatably connected to the second slide groove 6.

[0041] Specifically, it is ensured that when the first rotating rod 10 rotates, one end of the first rotating rod 10 can rotate normally within the second sliding groove 6. Furthermore, because the other end of the first rotating rod 10 is provided with anti-slip texture, when the user rotates the other end of the first rotating rod 10 by hand, the anti-slip texture can increase the friction between the user's hand and the other end of the first rotating rod 10. At the same time, it is ensured that when the one-way threaded rod 8 rotates, the one-way threaded rod 8 can rotate normally within the second sliding groove 6.

[0042] Example 7: This embodiment provides a container quick connection device, which, in addition to the technical solution of the above embodiment, also has the following technical features: the pull rod 3 is rotatably connected to the lock body 1, the two first pressing blocks 5 are located in the inner cavity of the lock body 1, and the upper and lower sides of one end of the second pressing block 7 are inclined.

[0043] Specifically, it is ensured that when the user pulls the lever 3 by hand, the lever 3 can rotate normally in the inner cavity of the lock body 1, and that when the two first pressing blocks 5 move, the two first pressing blocks 5 can enter the inner cavity of the lock body 1. At the same time, because the upper and lower sides of one end of the second pressing block 7 are inclined, when one end of the second pressing block 7 presses the two first pressing blocks 5, the two first pressing blocks 5 can move away from each other.

[0044] Working principle: When in use, the user pulls the lever 3 by hand, causing the lever 3 to rotate the lock cylinder 2 inside the lock body 1, ensuring that the whole device can be used normally. When the lever 3 is rotated to the appropriate position, the user rotates the first rotating rod 10 by hand, causing one end of the first rotating rod 10 to drive the one-way threaded rod 8 to rotate inside the second pressing block 7. The second pressing block 7 is moved along the second slide groove 6 by the thread action of the one-way threaded rod 8, causing one end of the second pressing block 7 to press the two first pressing blocks 5. The upper and lower sides of one end of the second pressing block 7 press the two first pressing blocks 5 respectively, causing the two first pressing blocks 5 to move away from each other along the two first slide grooves 4. When the two first pressing blocks 5 move away from each other, one end of the two first pressing blocks 5 will press the inner wall of the lock body 1, fixing the lever 3 in the inner cavity of the lock body 1 and preventing it from rotating, ensuring that the lever 3 will not be affected by external factors and will not rotate. In use, the user manually rotates the second rotating rod 16, causing one end of the second rotating rod 16 to drive the bidirectional threaded rod 14 to rotate within the limiting groove 11. This causes the two sliders 12 to be acted upon by the two sections of oppositely oriented threads on the bidirectional threaded rod 14, moving them closer or further apart along the limiting groove 11. Consequently, the two limiting grooves 11 respectively drive the two third pressing blocks 13 to move further or further apart within the pressing groove 17. When the two third pressing blocks 13 move further apart to a position where they cannot move, they will be tightly pressed against the inner wall of the pressing groove 17, fixing the first rotating rod 10 within the first rotating groove 9 and preventing it from rotating. This ensures that the first rotating rod 10 will not be affected by external factors and further improves the stability of the overall device.

Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
