Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0029] References to "one embodiment," "some embodiments," or "an embodiment" in this specification mean that a particular feature, structure, or characteristic described in conjunction with that embodiment is included in one or more embodiments of the present invention. Thus, phrases such as "in one embodiment," "in some embodiments," "in other embodiments," and "in other embodiments" appearing in various places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. Furthermore, in one or more embodiments, particular features, structures, or characteristics may be combined in any suitable manner.

[0030] When packing, large plate-shaped goods such as glass are placed in a vertical position against the inner wall of the container. Due to the large size and thinness of the goods, the goods loaded into the container are easy to fall over.

[0031] In the prior art, after cargo is pushed into a container, workers enter and use angled wooden bars to support the sides of the cargo to prevent it from tipping over. However, these angled wooden bars occupy a significant amount of space between the cargo and the container's inner walls. Because container loading and unloading operations are confined spaces, the working space within the container gradually decreases as cargo is gradually loaded. This smaller space makes it difficult to place these angled wooden bars, and unsupported cargo easily tips over.

[0032] In view of the above problems, an embodiment of the present application provides a supporting device, which is intended to support goods in a container and solve the technical problem that a smaller space is not conducive to placing inclined solid wood strips.

[0033] In order to illustrate the technical solution of the present application, the following description is given with reference to specific drawings and embodiments.

[0034] Please refer to Figure 1 and Figure 2, an embodiment of the present application provides a supporting device, including a main supporting frame 1, a container supporting frame 3 and a cargo supporting frame 2.

[0035] The main support frame 1 is used to be set on the bottom plate of the container; the container support frame 3 is connected to the main support frame 1, and the container support frame 3 protrudes from the main support frame 1, and the container support frame 3 is used to support the inner wall of the container; the cargo support frame 2 is connected to the main support frame 1, and the cargo support frame 2 protrudes from the main support frame 1 in a direction opposite to the protruding direction of the container support frame 3, and the cargo support frame 2 is used to support the cargo in the container.

[0036] Since the main support frame 1 is used to be set on the bottom plate of the container, the container abutment frame 3 protrudes from the main support frame 1, and the container abutment frame 3 is used to abut the inner wall of the container, the cargo support frame 2 protrudes from the main support frame 1 in a direction opposite to the protruding direction of the container abutment frame 3, and the cargo support frame 2 is used to support the cargo in the container, so when the supporting device is set in the container, the supporting device is located between two opposite inner walls of the container, the container abutment frame 3 abuts against one of the inner walls of the container, and clamps the cargo between the cargo support frame 2 and the inner wall of the container to prevent the cargo placed in the container from tipping over; at the same time, since the distance that the cargo support frame 2 protrudes from the main support frame 1 is adjustable, when the working space in the container gradually decreases, the distance that the cargo support frame 2 protrudes from the main support frame 1 can be adjusted, so that the supporting device is suitable for smaller spaces.

[0037] When using the support device of the embodiment of the present application to assist in packing, first use a forklift to place the goods into the container against the inner wall of the container, then place the support device into the container, and finally adjust the distance that the cargo support frame 2 protrudes from the main support frame 1 so that the cargo support frame 2 contacts and supports the goods.

[0038] It should be noted that when the supporting device of the embodiment of the present application is used, the supporting device is located in the horizontal direction of the container (with Figure 2 Between two opposite inner walls (parallel to each other in the X direction in the drawing), the container support frame 3 protrudes from one side of the main support frame 1 in the horizontal direction (one side in the X direction or the side opposite to the X direction), and the cargo support frame 2 protrudes from the opposite side of the main support frame 1 in the horizontal direction.

[0039] Please refer to Figure 2 and Figure 3 In some embodiments, the cargo support rack 2 includes a cargo support assembly 21, the cargo support assembly 21 includes a first support rod 211 and an adjustment rod 212, the first support rod 211 is rotatably connected to the main support frame 1, the adjustment rod 212 is rotatably connected to the first support rod 211, the adjustment rod 212 is connected to the main support frame 1, and the distance from the connection between the adjustment rod 212 and the main support frame 1 to the first support rod 211 is adjustable.

[0040] In the above embodiment, by changing the connection between the adjusting rod 212 and the support frame and the distance from the adjusting rod 212 to the first support rod 211, the first support rod 211 can be rotated relative to the main support frame 1 to change the inclination angle of the first support rod 211 relative to the main support frame 1, thereby changing the distance that the first support rod 211 protrudes from the main support frame 1.

[0041] Please refer to Figure 2 and Figure 3 In some embodiments, a plurality of first clamping structures 2121 are provided on the adjusting rod 212, and the plurality of first clamping structures 2121 are arranged at intervals. A second clamping structure 11 is provided on the main support frame 1, and the first clamping structure 2121 is detachably connected to the second clamping structure 11.

[0042] In the above embodiment, by connecting different first clamping structures 2121 with the second clamping structure 11, the connection between the adjusting rod 212 and the support frame and the distance from the adjusting rod 212 to the first support rod 211 can be changed, so that the first support rod 211 can be rotated relative to the main support frame 1, thereby changing the distance that the first support rod 211 protrudes from the main support frame 1.

[0043] Please refer to Figure 2 and Figure 3 In some embodiments, the first clamping structure 2121 is a clamping groove, and the second clamping structure 11 is a clamping column.

[0044] By adopting the above technical solution, the clamping column can enter or exit the clamping slot through the notch of the clamping slot, which facilitates the connection between the first clamping structure 2121 and the second clamping structure 11, and also facilitates the connection and separation of the first clamping structure 2121 and the second clamping structure 11.

[0045] Please refer to Figure 2 The notch of the clamping groove faces downward. When the first clamping structure 2121 is connected to the second clamping structure 11, the clamping column can support the clamping groove to prevent the adjustment rod 212 from rotating relative to the first support rod 211 under the action of its own gravity, thereby preventing the first clamping structure 2121 and the second clamping structure 11 from detaching from each other.

[0046] In some embodiments, the clamping column includes a clamping portion and a stop portion, the clamping portion passes through the clamping slot, and the stop portion is located on the side of the adjustment rod 212 away from the main support frame 1.

[0047] By adopting the above technical solution, the stop portion can limit the position of the adjustment rod 212 to prevent the adjustment rod 212 from being separated from the clamping column.

[0048] Please refer to Figure 4In some embodiments, the first support rod 211 includes a first telescopic sub-rod 2111, a second telescopic sub-rod 2112 and a first fastener 2113. The first telescopic sub-rod 2111 is provided with a first limiting cavity (not shown in the figure) extending in the axial direction of the first telescopic sub-rod 2111. The second telescopic sub-rod 2112 is slidably disposed in the first limiting cavity. The first fastener 2113 is detachably passed through the first telescopic sub-rod 2111 and the second telescopic sub-rod 2112; the first telescopic sub-rod 2111 or the second telescopic sub-rod 2112 is rotatably connected to the main support frame 1.

[0049] By adopting the above technical solution, the length of the first support rod 211 is adjustable, which can increase the adjustment range of the distance that the cargo support frame 2 protrudes from the main support frame 1, thereby increasing the versatility of the support device of the embodiment of the present application.

[0050] Please refer to Figure 4 Optionally, in the above embodiment, a first fastening hole 21111 is provided on the first telescopic sub-rod 2111, and a plurality of second fastening holes 21121 are provided on the second telescopic sub-rod 2112 and are spaced apart in the axial direction of the second telescopic sub-rod 2112, and the first fastener 2113 is detachably inserted into the first fastening hole 21111 and the second fastening hole 21121.

[0051] Optionally, in the above embodiment, the first telescopic sub-rod 2111 is provided with a plurality of first fastening holes 21111 distributed at intervals in the axial direction of the first telescopic sub-rod 2111, and the second telescopic sub-rod 2112 is provided with a second fastening hole 21121, and the first fastener 2113 is detachably inserted into the first fastening hole 21111 and the second fastening hole 21121.

[0052] Optionally, in the above embodiment, the first telescopic sub-rod 2111 is provided with a plurality of first fastening holes 21111 distributed at intervals in the axial direction of the first telescopic sub-rod 2111, and the second telescopic sub-rod 2112 is provided with a plurality of second fastening holes 21121 distributed at intervals in the axial direction of the second telescopic sub-rod 2112, and the first fastener 2113 is detachably inserted into the first fastening hole 21111 and the second fastening hole 21121.

[0053] Please refer to Figure 1 、 Figure 2 and Figure 5 In some embodiments, the container support frame 3 includes a second support rod 31 and a fixing member 32. The second support rod 31 is rotatably connected to the main support frame 1. The second support rod 31 is provided with a first plug hole 311, and the main support frame 1 is provided with a second plug hole 12. The fixing member 32 is detachably plugged into the first plug hole 311 and the second plug hole 12.

[0054] By adopting the above technical solution, the second support rod 31 can be rotatably connected to the main support frame 1, so that the second support rod 31 can be movable; when the fixing member 32 is inserted into the first plug hole 311 and the second plug hole 12, the position of the second support rod 31 will be fixed, and the second support rod 31 can protrude from the main support frame 1; when the fixing member 32 is removed from the first plug hole 311 and the second plug hole 12, the second support rod 31 can be moved relative to the main support frame 1 to be accommodated in the main support frame 1 or accommodated on one side of the main support frame 1, so as to facilitate the storage of the support device.

[0055] Please refer to Figure 2 In some embodiments, two groups of first plug holes 311 are provided, and the two groups of first plug holes 311 are located on both sides of the rotation axis of the second support rod 31; two groups of cargo support components 21 are provided, and the two groups of cargo support components 21 protrude from the main support frame 1 in two opposite directions respectively.

[0056] In the above embodiment, when the fixing member 32 is inserted into the second plugging hole 12 and the first plugging hole 311 located on one side of the rotation axis of the second support rod 31 (for example, on the side located in the X direction), the position of the second support rod 31 will be fixed, and the second support rod 31 will protrude from the main support frame 1 in a certain direction (for example, in the X direction); when the fixing member 32 is inserted into the second plugging hole 12 and the first plugging hole 311 located on the other side of the rotation axis of the second support rod 31 (for example, on the side located in the opposite direction of the X direction), the position of the second support rod 31 will be fixed, and the second support rod 31 will protrude from the main support frame 1 in the direction opposite to the above direction (for example, in the direction opposite to the X direction); so the protruding direction of the second support rod 31 can be changed by simply rotating the second support rod 31 and inserting the fixing member 32 into the first plugging hole 311 at different positions. Furthermore, since there are two groups of cargo support assemblies 21, the two groups of cargo support assemblies 21 protrude from the main support frame 1 in two opposite directions (for example, opposite in the X direction), so no matter in which direction the second support rod 31 protrudes from the main support frame 1, there is a first support rod 211 protruding from the main support frame 1 in a direction opposite to the protruding direction of the second support rod 31.

[0057] By adopting the above technical solution, when the goods are located in different directions of the supporting device, it is only necessary to rotate the second support rod 31 and insert the fixing member 32 into the first plug hole 311 at different positions without changing the orientation of the supporting device, which saves time and effort and can improve the packing efficiency of the goods.

[0058] Please refer to Figure 1 In some embodiments, the container support frame 3 further includes a connecting line 33 , one end of the connecting line 33 is connected to the fixing member 32 , and the other end of the connecting line 33 is connected to the second support rod 31 or the main support frame 1 .
