[0037] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0038] As Figures 1 to 5 shown, a self - hanging height compensator can be used between two upper and lower containers 10 that need to be stacked to compensate for the stacking height of these two containers 10. The self - hanging height compensator includes a support seat 1 with a predetermined height. A hook 2 is provided on the top surface of the support seat 1, and a card slot 3 is formed between the hook 2 and the top surface of the support seat 1. As Figure 6 and Figure 7 , during use, after the hook 2 extends into the corner fitting hole of the bottom corner fitting 20 of the container and rotates a certain angle, the card slot 3 can be made to catch the bottom wall of the corner fitting 20, and the support seat 1 is hung below the corner fitting 20.

[0039] A limiting shaft 4 that moves up and down relative to the support seat 1 is provided on one side of the card slot 3. The limiting shaft 4 can extend out of the top surface of the support seat 1 or retract below the top surface of the support seat 1. After the card slot 3 catches the inner wall of the hole of the angle member 20, the limiting shaft 4 extends out of the top surface of the support seat 1 and abuts against the side wall of the hole of the angle member 20. In this way, the hook 2 can no longer rotate, and the angle member 20 and the support seat 1 are reliably connected together, and the rotation of the hook 2 will not be caused by some shaking during the hoisting process of the container 10. When the limiting shaft 4 retracts below the top surface of the support seat 1 as shown in Figure 5 After that, the hook 2 can rotate.

[0040] The support seat 1 is square, and the hook 2 is inclined relative to the support seat 1 in the direction of the diagonal of the support seat 1. The card slot 3 is opened facing the support seat 1. The length of the hook 2 is greater than the width. The angle member 20 hole can be inserted in the width direction first, and then rotated so that the card slot 3 catches the bottom wall of the angle member 20. The card slots 3 are symmetrically opened on both sides of the support seat 1 to ensure stable connection.

[0041] A cavity 11 is formed inside the support seat 1. The setting of the cavity 11 removes some materials of the support seat 1, reduces the weight of the support seat 1, and a limiting hole 12 communicating with the cavity 11 is opened on the top surface of the support seat 1. A first position groove 13 and a second position groove 14 communicating with the cavity 11 are opened on the side wall of the support seat 1 on one side of the limiting hole 12. The first position groove 13 and the second position groove 14 have bottom surfaces with different heights, and the first position groove 13 and the second position groove 14 communicate with each other.

[0042] The bottom of the limiting shaft 4 is arranged inside the cavity, and its top is inserted into the limiting hole 12, and it can extend out of the top surface of the support seat 1 or retract below the top surface of the support seat 1 through the limiting hole 12. The bottom of the limiting shaft 4 is bent towards one side to form an operating shaft 5. The end of the operating shaft 5 can move between the first position groove 13 and the second position groove 14 and rest on the bottom surfaces with different heights. When the operating shaft 5 rests on the bottom surface of the first position groove 13, the limiting shaft 4 extends out of the top surface of the support seat 1 and is in the first position. When the operating shaft 5 rests on the bottom surface of the second position groove 14, the limiting shaft 4 retracts below the bottom surface of the support seat and is in the second position.

[0043] In another embodiment of the present invention, a pin 41 is inserted into the top of the limiting shaft 4. The two ends of the pin 41 extend out of the side wall of the limiting shaft 4 and contact the side wall of the hole of the angle member 20 through the pin 41 to abut against the side wall of the hole of the angle member 20 more tightly.

[0044] Under normal circumstances, when the containers 10 are stacked, two adjacent containers 10 above and below are connected by a safety single seat 30 to prevent the sliding of the containers 10. Then, when using the height compensator, the safety single seat 30 is also required to prevent the sliding between the containers 10. The above content has introduced that the height compensator can be connected to the corner fitting 20 of the container 10 above it through the hook 2 and the limit shaft 4. Then, a safety single seat 30 can be connected to the bottom of the support seat 1, and the safety single seat 30 is then connected to the corner fitting 20 of the container 10 at its bottom. Specifically, as Figure 8 and Figure 9 shown, a bottom hole 15 is opened on the bottom surface of the support seat 1, and the bottom hole 15 communicates with the inner cavity. The upper lock head of the safety single seat 30 can pass through the bottom hole 15 and enter the cavity 11 to clamp the bottom wall of the support seat 1 and connect with the support seat 1.

[0045] The hook 2 is integrally connected with the support seat 1, and the two can be integrally formed by casting during manufacturing. An inclined guiding surface is provided at the top of the hook 2, and the guiding surface facilitates the hook 2 to extend into the corner fitting 20.

[0046] The usage method of the present invention is as follows:

[0047] 1. Ensure that the limit shaft 4 retracts below the top surface of the support seat 1, that is, the self-hanging height compensator provided by the present invention is in the unlocked state, as Figure 10 shown;

[0048] 2. Align the hook 2 with the hole of the corner fitting 20 and then insert it into the hole of the corner fitting 20. Then rotate the hook 2 so that the clamping groove 3 clamps the bottom wall of the corner fitting 20, and the hook 2 is hung on the corner fitting 20, as Figure 11 shown;

[0049] 3. Move the operating shaft 5 to make the limit shaft 4 extend out of the top surface of the support seat 1. The limit shaft 4 clamps the side wall of the hole of the corner fitting 20, and the hook 2 can no longer rotate, that is, the self-hanging height compensator provided by the present invention is in the locked state, as Figure 12 shown.

[0050] 4. The upper lock head of the safety single seat 30 passes through the bottom hole 15 and enters the inner cavity to clamp the bottom wall of the support seat 1 and connect with the support seat 1, as Figure 13 shown.

[0051] 5. All the above operations can be completed by workers at the dock. Then, the container 10 equipped with the self-hanging height compensator and the safety single seat 30 provided by the present invention is transferred from the dock to the cabin. The lower lock head of the safety single seat 30 is aligned with the corner fitting hole of the lower-layer container 10, and the lower lock head of the landing container safety single seat 30 is connected to the corner fitting hole of the lower-layer container 10 to complete the loading, as Figure 14 and Figure 15 shown.

[0052] 6. When disassembly is required, reverse the operations in steps 1 to 5 above.

[0053] In summary, for the self-hanging height compensator provided by the present invention, when in use, it is first hung on the bottom of the corner fitting 20 at the bottom of the container 10 through the hook 2, and the limit shaft 4 on one side of the hook 2 can prevent the hook 2 from rotating further after it extends, making the connection between the present invention and the corner fitting 20 more firm.

[0054] A cavity 11 is formed inside the support seat 1. The bottom hole 15 opened at the bottom of the support seat 1 and communicating with the cavity 11 enables the safety single seat 30 to be connected to the bottom of the support seat 1, and the safety single seat 30 is then connected to the lower container 10. Through the limit holes 12, the first position groove 13, the second position groove 14 and the bottom hole 15 opened around the cavity 11, the cavity 11 cleverly accommodates the locking head of the safety single seat 30, the limit shaft 4 and the operating shaft 5, making the structure of the present invention more compact, and the cavity 11 itself can reduce a part of the weight of the present invention, and the present invention is also more convenient to use.

[0055] Since the support seat 1 has a predetermined height, it can compensate for the height difference when the containers 10 are stacked, so that the top heights of two adjacent stacks of containers 10 are kept consistent, and the two stacks of containers 10 can be connected by a bridge-shaped connector 40.
