For ordinary skilled in the art, the above-mentioned belongs to the specific meaning in the utility model can be understood according to the specific circumstances.

[0022] Some embodiments of the utility model, including lock rod 1 and two lock hooks 2, each lock hook 2 includes collar 21 and hook piece, two collars 21 are respectively connected with the both ends of lock rod 1 through thread, still include top rod 22 hook piece;3 and two fasteners 4, each fastener 4 includes hanging ring 41 and sleeve 42, the both ends of lock rod 1 are arranged in two hanging rings 41, and the both ends of top rod 22 hook piece;3 are respectively connected with two sleeves 42 through thread.

[0023] Specifically, the container bridge lock mainly includes lock rod 1, two lock hooks 2, top rod 22 hook piece;3 and two fasteners 4. Each lock hook 2 is composed of collar 21 and hook piece, and each fastener 4 is composed of hanging ring 41 and sleeve 42. The lock rod 1 is long strip-shaped, is located in the upper main position of the bridge lock, and the collars 21 of the two lock hooks 2 are located at the both ends of the lock rod 1 and are connected with the lock rod 1 through thread. The hanging rings 41 of the two fasteners 4 are sleeved on the both ends of the lock rod 1, and the top rod 22 hook piece;3 is located below the lock rod 1, and the both ends thereof are connected with the two sleeves 42 through thread. From the spatial layout, the lock hook 2 is used for being connected with the container corner piece 5 and is located at the outer side position of the bridge lock, the fastener 4 is located at the relatively inner side position, and the top rod 22 hook piece;3 is located at the middle lower position, and this layout lays a foundation for realizing the synergistic effect of pulling force and supporting force. The collar 21 is connected with the lock rod 1 through thread, so that the collar 21 can rotate on the lock rod 1 and move along the axial direction, and this connection mode facilitates the adjustment of the position of the lock hook 2. The hanging ring 41 is in penetrating relationship with the lock rod 1, that is, the lock rod 1 penetrates through the hanging ring 41, and the hanging ring 41 can have a certain degree of rotational freedom relative to the lock rod 1. The top rod 22 hook piece;3 is connected with the sleeve 42 through thread, and the sleeve 42 can rotate on the top rod 22 hook piece;3 and move along the axial direction, so as to realize the adjustment of the length of the top rod 22 hook piece;3.

[0024] Working principle: When installing, first screw the collars 21 of the two hooks 2 at appropriate positions on both ends of the lock rod 1, at which time the distance between the hooks 2 can be preliminarily adjusted. Then pass the lock rod 1 through the hanging rings 41 of the two fasteners 4. Next, screw the sleeves 42 at both ends of the top rod 22 hook 3 on the top rod 22 hook 3 at appropriate positions. When connecting the containers, by rotating the collars 21 to move on the lock rod 1, the distance between the two hooks 2 is further adjusted, and the hooks 2 are hooked to the container corner fittings 5 to exert a pulling force. At the same time, when there is a gap between adjacent containers, by rotating the sleeves 42 to move on the top rod 22 hook 3, the effective length of the top rod 22 hook 3 is adjusted, so that the sleeves 42 at both ends of the top rod 22 hook 3 are tightly attached to the container corner fittings 5, thereby providing a supporting force.

[0025] Technical effect: The structure design makes the bridge lock not only provide a pulling force through the hooks 2, but also provide a supporting force through the top rod 22 hook 3, realizing the two-way binding of adjacent containers. It can effectively deal with the large gap between containers, avoid the containers from shaking and shifting during transportation, greatly improve the stability of container connection and the safety of transportation. At the same time, the threaded connection between the parts facilitates installation and disassembly, improving the convenience of operation.

[0026] In some embodiments of the utility model, the distance between the two hooks 2 is greater than the distance between the two fasteners 4.

[0027] Specifically, the installation positions of the two hooks 2 on the lock rod 1 make the distance between them greater than the distance between the two fasteners 4. Specifically, starting from one end, the collar 21 of the hook 2 is installed first, followed by the hanging ring 41 of the fastener 4, and the hook 2 is on the outside and the fastener 4 is on the inside. This layout makes the distance between the hooks 2 greater than the distance between the fasteners 4.

[0028] Because the distance between the two hooks 2 is greater than the distance between the two fasteners 4, when connecting the containers, the hooks 2 can be hooked to the corner fittings 5 of the containers first, at which time the force point of the pulling force is formed. Then by adjusting the positions of the fasteners 4 and the top rod 22 hook 3, the top rod 22 hook 3 can better play a supporting role. For example, when the distance between the containers is large, by adjusting the position of the hook 2 on the lock rod 1 and the length of the top rod 22 hook 3, the pulling force and the supporting force of the bridge lock can work together to tightly connect the two containers and effectively limit the left and right movement of the containers. This layout design can better adapt to the connection of containers with different distances, especially large gaps. By reasonably distributing the force points of the pulling force and the supporting force, the use performance of the bridge lock under different working conditions is improved, the stability and reliability of the connection are further enhanced, and the safety of the containers during transportation is ensured.

[0029] In some embodiments of the utility model, the two sleeves 21 and the two connecting parts are two screwing parts, and the screwing directions of the two screwing parts are opposite.

[0030] Specifically, the part where the two sleeves 21 are connected with the lock rod 1 is a screwing part, and the screwing directions of the two screwing parts are opposite. This means that when the lock rod 1 is rotated, the two sleeves 21 will move in opposite directions on the lock rod 1. For example, if the lock rod 1 is rotated clockwise, one sleeve 21 will move towards one end of the lock rod 1, and the other sleeve 21 will move towards the other end of the lock rod 1.

[0031] Working principle: when adjusting the bridge lock to adapt to the distance between containers, by rotating the lock rod 1 and using the opposite screwing directions of the two screwing parts, the positions of the two hooks 2 can be adjusted simultaneously. When facing a container with a large gap, the operator only needs to rotate the lock rod 1 to make the two hooks 2 move synchronously towards or away from each other, quickly adjust to the appropriate position, and better hook the container corner fittings 5 to apply tension. At the same time, this synchronous adjustment also provides better conditions for the subsequent support of the top rod 22 hook fittings 3, so that the tension and support force can work more coordinately.

[0032] Technical effect: this design simplifies the adjustment operation of the bridge lock, improves the adjustment efficiency, and reduces the workload of the operator. When handling the connection of a container with a large gap, the distance between the two hooks 2 can be adjusted more quickly and accurately, so that the tension can be applied more effectively, and the support force of the top rod 22 hook fittings 3 can be coordinated to realize the two-way binding of the container, greatly enhancing the practicality and adaptability of the bridge lock.

[0033] In some embodiments of the utility model, the two fasteners 4 and the two sleeves 42 connecting parts are two screwing parts, and the screwing directions of the two screwing parts are opposite.

[0034] Specifically, the part where the sleeves 42 of the two fasteners 4 are connected with the top rod 22 hook fittings 3 is a screwing part, and the screwing directions of the two screwing parts are opposite. Similar to the connection of the sleeves 21 and the lock rod 1, when the top rod 22 hook fittings 3 are rotated, the two sleeves 42 will move in opposite directions on the top rod 22 hook fittings 3.

[0035] Working principle: when adjusting the length of the hook piece 3 of the top rod 22, by rotating the hook piece 3 of the top rod 22, the positions of the two sleeves 42 can be adjusted simultaneously by using the opposite thread directions of the two screwing parts, so as to change the effective length of the hook piece 3 of the top rod 22. When facing a large-gap container and when it is necessary to increase the length of the hook piece 3 of the top rod 22 to provide sufficient supporting force, the hook piece 3 of the top rod 22 is rotated, and the two sleeves 42 will move to the two ends of the hook piece 3 of the top rod 22 respectively, so that the hook piece 3 of the top rod 22 is elongated; on the contrary, it is shortened. In this way, the supporting force of the hook piece 3 of the top rod 22 can be quickly and accurately adjusted, and the pulling force of the lock hook 2 is matched to realize the two-way limiting binding of the container.

[0036] Technical effect: this design makes the adjustment of the length of the hook piece 3 of the top rod 22 more convenient and fast, and can quickly adapt to the requirements of containers with different spacings, especially large spacings. By accurately adjusting the supporting force of the hook piece 3 of the top rod 22 and the pulling force of the lock hook 2, the adjusting performance and use convenience of the bridge lock are improved, and the connection stability and reliability of the large-gap container are further enhanced.

[0037] In some embodiments of the utility model, the sleeve ring 21 and the hook piece are fixedly connected.

[0038] Specifically, the sleeve ring 21 and the hook piece are fixedly connected, for example, they can be firmly connected together by welding, riveting and the like. This fixed connection makes the sleeve ring 21 and the hook piece form an integral component and will not relatively displace during use.

[0039] In some embodiments of the utility model, the hanging ring 41 and the sleeve 42 are fixedly connected.

[0040] Specifically, the hanging ring 41 and the sleeve 42 are fixedly connected, which can also be realized by welding, riveting and the like. This fixed connection makes the hanging ring 41 and the sleeve 42 form an integral component and will not relatively displace during use.

[0041] In some embodiments of the utility model, the container bridge lock comprises the above-mentioned container bridge lock, the hook pieces of the two lock hooks 2 are respectively hooked to the two adjacent corner pieces 5, and the sleeves 42 of the two fasteners 4 are respectively tightly attached to the two adjacent corner pieces 5.

[0042] Specifically, in actual use, the hook members of the two hooks 2 are hooked on the corner fittings 5 of the two adjacent containers respectively, and the sleeves 42 of the two fasteners 4 are tightly attached to the corner fittings 5 of the two adjacent containers respectively. From the spatial position, the bridge lock is horizontally arranged between the two containers, and the hooks 2 and the fasteners 4 are tightly matched with the corner fittings 5 of the containers respectively to form a complete connection structure. The hooks 2 of the bridge lock are connected with the holes of the corner fittings 5 of the containers through the hook members to form a transmission path of the pulling force, and the sleeves 42 of the fasteners 4 are tightly attached to the surfaces of the corner fittings 5 of the containers to form a transmission path of the supporting force. At the same time, the connection relationship between the internal components (such as the lock rod 1, the hook member 3, the sleeve 42, etc.) of the bridge lock is as described above, and the components are matched with each other to realize the cooperative action of the pulling force and the supporting force.

[0043] Working principle: when connecting the containers, first place the bridge lock between the two containers, align the hook members of the hooks 2 with the holes of the corner fittings 5 of the containers, then rotate the lock rod 1 or the sleeve 21 to adjust the position of the hooks 2, so that the hook members are hooked on the corner fittings 5 to exert the pulling force. Then, rotate the hook member 3 of the top rod 22 or the sleeve 42 to adjust the length of the hook member 3 of the top rod 22, so that the sleeve 42 of the fastener 4 is tightly attached to the corner fitting 5 of the container to provide the supporting force. During the transportation process, the pulling force and the supporting force of the bridge lock cooperate with each other to effectively limit the left and right movement of the containers, and ensure the stability of the containers during the transportation process.

[0044] Technical effect: the design of the bridge lock set can realize reliable connection of adjacent containers, and through the cooperative work of the components of the bridge lock, the pulling force and the supporting force are provided at the same time, which effectively adapts to the connection requirement of the large-gap containers. Compared with the traditional bridge lock, the safety and stability of the container transportation are greatly improved, the shaking and displacement risk of the containers during the transportation process due to the gap is reduced, and the safety of the cargo transportation is ensured.

[0045] In some embodiments of the utility model, the hook member is inwardly curved and matched with the hole of the corner fitting 5.

[0046] Specifically, the hook member is designed to be inwardly curved, and its shape is matched with the hole of the corner fitting 5 of the container. When the bridge lock connects the containers, the curved part of the hook member can be accurately inserted into the hole of the corner fitting 5 of the container to form a tight hooking connection, so that the pulling force can be stably transmitted to the container. When the hook 2 of the bridge lock is connected with the corner fitting 5 of the container, since the hook member is inwardly curved and matched with the hole of the corner fitting 5, the operator only needs to align the hook member with the hole, and then appropriately adjust the position of the hook 2, so that the hook member can be smoothly inserted into the hole. During the transportation process, this matched hooking connection mode can effectively prevent the hook member from being pulled out of the hole of the corner fitting 5, ensure the continuous and stable transmission of the pulling force, better cooperate with the supporting force of the hook member 3 of the top rod 22, and realize the bidirectional limiting binding of the container.

[0047] The utility model has the advantages of the following beneficial effects:

[0048] The design of the structure makes the bridge lock can provide pulling force through the lock hook 2 and can provide supporting force through the top rod 22 hook piece 3, realizes the two-way binding of the adjacent containers, can effectively deal with the large gap between the containers, avoids the shaking and displacement of the containers in the transportation process, and greatly improves the stability of the container connection and the safety of the transportation.

[0049] The above is only the principle and the preferred embodiment of the utility model. It should be pointed out that, for ordinary skilled person in the art, on the basis of the principle of the utility model, a plurality of other variants can also be made, and should be regarded as the protection scope of the utility model.
