Description

Technical Field

[0001] This invention belongs to the field of container technology, and particularly relates to container hinges and containers. Background Technology

[0002] A collapsible container is a type of rack-mounted container that includes a cargo-carrying frame and collapsible end walls at both ends of the frame. Typically, collapsible containers are used with the end frames upright for loading. When returning empty, the end frames are folded down to reduce height. Multiple collapsible containers can be linked together for transport as a single container, reducing return transport costs.

[0003] When the end wall of the folding box moves from the folded state to the vertical position, it is usually locked by a pin. After the pin is in place, it needs to be limited again to prevent the pin from shifting. Currently, there are many structural components, a large amount of assembly, and many operation steps. Summary of the Invention

[0004] To solve the above problems, the present invention adopts the following technical solution:

[0005] The first aspect of the present invention relates to A hinge assembly includes an inner hinge and an outer hinge that are hinged to each other. The outer hinge is connected to the inner hinge hinge portion at its lower part. The inner hinge has a waist-shaped hole, and the outer hinge has a limiting hole corresponding to the waist-shaped hole. The waist-shaped hole and the limiting hole can simultaneously accommodate the same limiting member.

[0006] The limiting hole includes an arc-shaped hole portion and a limiting hole portion, as well as a switching hole connecting the arc-shaped hole portion and the limiting hole portion. When the limiting member passes through the arc-shaped hole portion and the waist-shaped hole simultaneously, the inner hinge can rotate relative to the outer hinge. When the limiting member passes through the limiting hole portion and the waist-shaped hole simultaneously, the inner hinge is limited relative to the outer hinge.

[0007] It should be noted that: 1) The inner hinge is limited relative to the outer hinge, meaning that the two cannot rotate relative to each other in this state; 2) The waist-shaped hole is a general term for hole type, which is not circular, and in some cases it can be a non-through hole; 3) The limiting hole can be in the form of a through hole and a non-through hole, and its main function is to guide and limit the movement of the limiting component.

[0008] In some embodiments, the outer hinge joint is connected to the inner arc side of the arc-shaped hole, and the limiting hole is located below one end of the arc-shaped hole; the waist-shaped hole is arranged along the longitudinal direction of the inner hinge. The longitudinal direction refers to the longitudinal direction of the inner hinge in its vertical state, to ensure that the length direction of the waist-shaped hole matches the vertical direction when the inner hinge is vertical.

[0009] In some embodiments, when the inner hinge rotates to a vertical position, the waist-shaped hole coincides with the limiting hole and the switching hole, and the limiting member can move up and down simultaneously in the waist-shaped hole and the limiting hole.

[0010] In some embodiments, when the inner hinge rotates to a vertical position, the switching hole coincides with the upper part of the waist-shaped hole, and the limiting hole coincides with the lower part of the waist-shaped hole.

[0011] In some embodiments, the limiting hole is vertically disposed in the outer hinge; the arc-shaped hole is horizontally disposed in the outer hinge.

[0012] In some embodiments, the arc-shaped hole is centered on the outer hinge joint; the outer hinge joint is located below the arc-shaped hole.

[0013] In some configurations, the inner hinge is used to connect to the end wall; the outer hinge is used to connect to the base plate.

[0014] The second aspect of the present invention relates to A container hinge, including any of the hinge components described above; wherein the same limiting member is provided in the waist-shaped hole and the limiting hole, and when the limiting member reaches the switching hole, the limiting member has a tendency to move toward the limiting hole portion.

[0015] In some examples, the limiting component is set as a limiting post, and this limiting post has a certain self-weight, thereby ensuring that the limiting post can fall from the switching hole into the limiting hole by gravity when the inner hinge is vertical. In order to make the limiting post move more stably, and the limiting post is perpendicular to the inner hinge and the outer hinge, both ends of the limiting post can move smoothly.

[0016] The third aspect of the present invention relates to A shipping container includes any of the hinge assemblies described above; wherein the lower part of the outer hinge is connected to the bottom plate, and the upper part of the inner hinge is connected to the folding end wall of the container; the folding end wall is hinged to the container bottom plate by the hinge assembly. The folding end wall mentioned in this section may include container side panels and end posts, etc., and the hinge assembly may be connected to any of the container floor, bottom plate beams, or bottom plate corner fittings.

[0017] The fourth aspect of the present invention relates to Internal hinge, including

[0018] The flip end is used to connect to the folding end wall, but it does not limit the folding end wall to be fixedly connected to this part. It only means that this part faces the folding end wall and flips with the folding end wall.

[0019] The hinge end has an outer hinge hinge part on one side of its end for hinged with the outer hinge.

[0020] A limiting portion, located between the flip end and the hinge end, is used to accommodate a limiting member from the outer hinge. The limiting portion is an oblong hole, and the length of the oblong hole is aligned with the longitudinal direction of the inner hinge. In some cases, the flip end, hinge end, and limiting portion form a triangular shape.

[0021] The beneficial effects of this invention are:

[0022] The inner hinge drives the end wall to rotate around the inner hinge rotation axis. At the same time, the inner hinge locking pin rotates synchronously along the track notch on the outer hinge. When the end wall rotates from the folded position to the vertical position, the inner hinge locking pin falls to the bottom along the waist hole on the inner hinge to achieve the locking effect. The locking structure is simplified, the assembly amount is reduced, and the cost is reduced. Attached Figure Description

[0029] The invention will now be further described with reference to the accompanying drawings.

[0030] Hinge components, such as Figures 1-2 As shown, the hinge assembly includes an inner hinge 100 and an outer hinge 200 that are hinged to each other. The inner hinge 100 is connected to the outer hinge 110 via a lower inner hinge hinge joint. The inner hinge 100 has a waist-shaped hole 120, and the outer hinge 200 has a limiting hole 210 corresponding to the waist-shaped hole 120. The waist-shaped hole 120 and the limiting hole 210 can simultaneously accommodate the same limiting member 121. This hinge assembly does not include the limiting member 121, but the corresponding functional positions all provide space for the limiting member 121. In addition, the waist-shaped hole 120 can be a through hole or a waist-shaped groove on one side of the inner hinge 100. The limiting hole 210 of the outer hinge 200 can also be a through hole or a groove, but it is still necessary to ensure that the same limiting member 121 can be installed between the two.

[0031] The limiting hole 210 includes an arc-shaped hole portion 211 and a limiting hole portion 212, as well as a switching hole 213 connecting the arc-shaped hole portion 211 and the limiting hole portion 212. When the limiting member 121 passes through the arc-shaped hole portion 211 and the waist-shaped hole 120 at the same time, the inner hinge 100 can rotate relative to the outer hinge 200. When the limiting member 121 passes through the limiting hole portion 212 and the waist-shaped hole 120 at the same time, the inner hinge 100 is limited relative to the outer hinge 200.

[0032] The outer hinge 200 can be in the form of two outer hinge plates, with the inner hinge 100 positioned between the two outer hinge plates. In this case, a limiting hole 210 is provided on at least one outer hinge plate. When both outer hinge plates are provided with limiting holes 210, one limiting hole 210 can be a through hole and the other limiting hole 210 can be a limiting groove. To facilitate unlocking, allowing the limiting member 121 to move upward from the limiting hole 212 into the switching hole 213, a through hole can be provided on at least one outer hinge plate to allow the limiting member to extend and form an adjustment handle. Of course, when the limiting member 121 is not extended, other means can be used to adjust the vertical position of the limiting member 121, such as using magnetic traction.

[0033] Regarding the waist-shaped hole 120, it can be as follows: Figure 3 The shape shown can also be an elongated structure. It provides space for the limiting member 121 to move in one specific direction, but restricts the movement of the limiting member 121 in another direction.

[0034] During implementation, the widths of the waist-shaped hole 120, the arc-shaped hole 211, the limiting hole 212, and the switching hole 213 can be set to be similar and matched with the outer diameter of the limiting member 121.

[0035] like Figure 4 As shown, the outer hinge joint is located on the inner arc side of the arc-shaped hole 211, and the limiting hole 212 is located below one end of the arc-shaped hole 211; the waist-shaped hole 120 is arranged along the longitudinal direction of the inner hinge 100. When the inner hinge 100 rotates relative to the outer hinge 200, the waist-shaped hole 120 always partially coincides with the arc-shaped hole 211. In specific applications, the outer hinge joint can be located at the arc center of the arc-shaped hole 211, or more specifically, the arc-shaped hole 211 can be centered on the outer hinge joint; the outer hinge joint is located below the arc-shaped hole 211. The outer hinge joint can also be less strictly positioned at the arc center; when the position of the outer hinge joint shifts, the presence of the waist-shaped hole 120 still ensures that the inner hinge 100 can rotate relative to the outer hinge 200 with the outer hinge joint as the axis.

[0036] like Figure 5As shown, when the inner hinge 100 rotates to a vertical position, the waist-shaped hole 120 coincides with the limiting hole portion 212 and the switching hole 213, and the limiting member 121 can move up and down simultaneously in the waist-shaped hole 120 and the limiting hole portion 212. Under the action of gravity, the limiting member 121 tends to maintain the bottom of the limiting hole portion 212, so when an external force acts on the inner hinge 100, the limiting member 121 plays a resisting role in the limiting hole portion 212, preventing the inner hinge 100 from rotating relative to the outer hinge.

[0037] When the inner hinge 100 rotates to the vertical position, the switching hole 213 coincides with the upper part of the waist-shaped hole 120, and the limiting hole 212 coincides with the lower part of the waist-shaped hole 120.

[0038] In practical applications, the limiting hole 212 is vertically arranged in the outer hinge 200, which makes it easier for the gravity of the limiting member 121 to take effect; the arc-shaped hole 211 is horizontally arranged in the outer hinge 200, so that the arc-shaped hole 211 and the limiting hole 212 form an angle, which also prevents the limiting member 121 from sliding freely from the limiting hole 212 into the arc-shaped hole 211.

[0039] The inner hinge 100 is used to connect the end wall; the outer hinge 200 is used to connect the base plate.

[0040] A container hinge, including the aforementioned hinge assembly, wherein the same limiting member 121 passes through the waist-shaped hole 120 and the limiting hole 210, and when the limiting member 121 reaches the switching hole 213, the limiting member 121 tends to move towards the limiting hole portion 212. In this container hinge, the limiting member 121 is pre-installed in the hinge assembly, and the limiting member 121 moves accordingly as the inner hinge rotates. The aforementioned hinge assembly has space for installing the limiting member 121, but it is not strictly required that the limiting member 121 be pre-installed, because the limiting member 121 can be inserted when needed, for example, when the inner hinge 100 is vertical, the limiting member 121 can be inserted from one end of the limiting hole portion 212 and simultaneously inserted into the waist-shaped hole 120. The tendency of the limiting member 121 to move towards the limiting hole 212 is mainly due to the gravity of the limiting member 121. In some cases, the force that allows the limiting member 121 to move towards the limiting hole 212 can also be provided by an actuating component. In this case, if the limiting member 121 enters the arc-shaped hole 211, the limiting effect of the arc-shaped hole 211 will counteract the force exerted by the actuating component on the limiting member 121, preventing it from moving accordingly. The two outer hinge plates can be arranged symmetrically, and both have the same structure.

[0041] The limiting member 121 is a limiting post, and the limiting post is perpendicular to the inner hinge 100 and the outer hinge 200.

[0042] The container includes the aforementioned hinge assembly; wherein the lower part of the outer hinge 200 is connected to the bottom plate, and the upper part of the inner hinge 100 is connected to the folding end wall of the container; the folding end wall is hinged to the container bottom plate by the hinge assembly. For the specific installation method of this hinge assembly on the container body, refer to existing technology.

[0043] Those skilled in the art will appreciate that various modifications to the above embodiments can be made without departing from the overall spirit and concept of the present invention. All such modifications fall within the protection scope of the present invention. The protection scheme of the present invention is defined by the appended claims.
