Description

Technical Field

[0001] This utility model relates to the field of marine tool technology, and in particular to a marine container locking structure. Background Technology

[0002] Marine container locking systems are systems used to securely fasten containers to ships, ensuring that containers do not shift or fall during transport, especially in rough seas. Marine container locking systems generally include: fixed lashing devices, movable lashing devices, and other locking structures. Among these, twist locks play a crucial role in the connection and locking between containers, effectively preventing lateral tilting and horizontal slippage, thus avoiding the inconvenience caused by horizontal slippage between containers.

[0003] Currently, the twist lock locking structure of existing marine containers on the market has a relatively poor embedding effect, which easily leads to a gap thickness between containers, which is not conducive to the stacking and stress of containers, and thus not conducive to ensuring the service life of the containers. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a marine container locking structure that solves the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A marine container locking structure includes a transverse platform section. The transverse platform section has arc-shaped grooves on its front and rear sides. A through slot runs longitudinally through the middle of the transverse platform section. A longitudinal platform section is integrally fixed to the middle of the through slot. A locking corner lug is integrally fixed to the top surface of the transverse platform section. The locking corner lug and the top of the longitudinal platform section are fixedly and integrally provided with protruding locking lugs. A bottom locking arm is integrally connected to the bottom surface of the transverse platform section. The bottom locking arm has a locking groove running through it, and the bottom end of the bottom locking arm is integrally fixed to the bottom end of the longitudinal platform section.

[0007] Preferably, the through slot is a rectangular through slot structure, and the bottom end of the locking corner lug is located at the corner of the through slot. There are two locking corner lugs, and the two locking corner lugs are located on the top surface of the horizontal platform piece near the diagonal opposite side of the through slot.

[0008] Preferably, there are two protruding locking ears, and the two protruding locking ears are fixed and integrally connected to two locking support corner posts, and the protruding directions of the two protruding locking ears are opposite to each other.

[0009] Preferably, there are two bottom locking inclined arms, and the two bottom locking inclined arms are located on the bottom surface of the horizontal platform piece near the middle of the two sides of the through slot.

[0010] Preferably, the bottom ends of the two bottom locking inclined arms are fixedly connected to the bottom of the two sides of the longitudinal platform plate, and both the bottom of the bottom locking inclined arms and the bottom of the longitudinal platform plate are conical.

[0011] Preferably, the outwardly protruding portion of the externally protruding locking ear is a convex angle structure with an arc edge.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This type of marine container locking structure is composed of a cross-shaped sheet structure (transverse platform section and longitudinal platform section) that is positioned at the corner of the container stack. The two outwardly protruding locking lugs lock the frame corners of the containers on both sides, making it easy for the bottom locking arm and longitudinal platform section to fit into the corner of the container stack. The locking structure is also relatively thin, avoiding an increase in the gap thickness between containers, which greatly benefits the stress on the stacked containers and ensures the effective service life of the containers.

[0018] 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.

[0019] Reference Figure 1-3A marine container locking structure includes a horizontal platform section 1, with arc-shaped grooves 2 on both the front and rear sides of the horizontal platform section 1. A through slot 3 is longitudinally opened through the middle of the horizontal platform section 1. A longitudinal platform section 4 is integrally fixed in the middle of the through slot 3 of the horizontal platform section 1. A locking corner truss 5 is integrally fixed on the top surface of the horizontal platform section 1. The locking corner truss 5 and the top of the longitudinal platform section 4 are fixed and integrally provided with an outwardly protruding locking lug 6. A bottom locking inclined arm 7 is integrally connected to the bottom surface of the horizontal platform section 1. A locking groove 8 is opened through the bottom locking inclined arm 7, and the bottom end of the bottom locking inclined arm 7 is integrally fixed to the bottom end of the longitudinal platform section 4.

[0020] In this utility model, the through slot 3 is a rectangular through slot structure, and the bottom end of the locking corner lug 5 is located at the corner of the through slot 3. There are two locking corner lugs 5, and the two locking corner lugs 5 are located on the top surface of the horizontal platform piece 1 near the diagonal opposite side of the through slot 3.

[0021] More specifically, by setting a through-hole 3 in a rectangular through-hole, the entire structure becomes lighter, reducing its weight and material costs.

[0022] In this utility model, there are two protruding locking ears 6, and the two protruding locking ears 6 are respectively fixed and integrally connected to two locking support corner ear posts 5, and the protruding directions of the two protruding locking ears 6 are set opposite to each other.

[0023] More specifically, by setting two outwardly protruding locking ears 6 to be fixed and integrally connected with two locking support corner ear posts 5 respectively, the overall stability is better and the deformation resistance is better.

[0024] In this utility model, there are two bottom locking inclined arms 7, and the two bottom locking inclined arms 7 are located on the bottom surface of the horizontal platform plate 1 near the middle of the two sides of the through slot 3.

[0025] More specifically, by setting two bottom locking inclined arms 7 located on the bottom surface of the horizontal platform piece 1 near the middle of the two sides of the through slot 3, respectively, the stability of the entire structure is further increased.

[0026] In this utility model, the bottom ends of the two bottom locking inclined arms 7 are fixedly connected to the bottom of the two sides of the longitudinal platform plate 4, and the bottom of both the bottom locking inclined arms 7 and the bottom of the longitudinal platform plate 4 are conical.

[0027] More specifically, by setting the bottom of both the bottom locking inclined arm 7 and the bottom of the longitudinal platform piece 4 to be conical, it is easier to embed the bottom into the corner of the container stack.

[0028] In this utility model, the outward protrusion of the outer locking ear 6 is a convex corner structure with an arc edge;

[0029] More specifically, by setting a convex corner structure with an arc edge as an outwardly protruding locking lug 6, it is very convenient to slide and fasten during the fastening process.

[0030] In summary, by setting the entire twist-locking structure to consist of a cross-shaped sheet structure (horizontal platform piece 1 and longitudinal platform piece 4), the entire structure is positioned at the corner of the container stack. This allows the two outwardly protruding locking lugs 6 to lock the corners of the container frames on both sides, making it easy for the bottom locking arm 7 and the longitudinal platform piece 4 to fit into the corner of the container stack. Furthermore, the locking structure has a relatively small thickness, avoiding an increase in the thickness of the gap between containers. This greatly benefits the stress distribution of the stacked containers and ensures the effective service life of the containers. It also solves the problem of the locking structure increasing the thickness of the gap between containers.
