Description

Technical Field

[0001] The utility model relates to containing equipment, in particular to a container and a side plate thereof. Background Art

[0002] In existing foldable containers, the maximum height of the side panels generally does not exceed the length of the base minus the thickness of the side panels, otherwise it will affect the folding of the side panels (cannot be folded and flattened). When the length and width of the base are limited, the maximum height of the side panels is also limited accordingly. If you want to increase the volume of the container, you generally need to keep the bottom surface of the base unchanged and increase the height of the base to increase the height of the container to achieve the purpose of increasing the volume of the container.

[0003] However, as the height of the base increases, the total height of the foldable container after folding also increases. During the recycling and transportation process, such foldable containers are generally transported by containers, vans, etc., and the total height of the foldable container after folding determines the number of boxes packed in the container or van. The higher the total height of the foldable container after folding, the smaller the corresponding number of recycled boxes, which greatly increases the recycling and transportation costs. At the same time, in warehouse management, the total height of the foldable container after folding determines the number of stacking in the warehouse. The higher the total height of the foldable container after folding, the smaller the corresponding number of stacking in the warehouse, which not only increases the storage costs, but also indirectly increases the turnover cost of the container.

[0004] In addition, increasing the height of the side panels can also increase the volume of the container, but the increased height of the side panels will exceed the length and width of the base after folding, so the side panels must be folded in half before folding. This method not only increases the number of operation steps and increases the difficulty of operation, but also increases the height of the base as the thickness of the side panels increases after folding, which increases the total height of the container after folding, greatly reducing the recycling rate. Utility Model Content

[0005] The utility model aims to provide a container and a side plate thereof, so that the high end of the side plate can be adjusted without increasing the thickness of the side plate.

[0058] Embodiments of the present invention are described below with reference to the accompanying drawings.

[0059] An embodiment of the present invention relates to a side plate 101 of a container 100. Figure 1 , Figure 4 As shown, the container 100 is a foldable container 100, comprising: a base 6, a pair of first side panels arranged oppositely, and a pair of second side panels 102 arranged oppositely, wherein the first side panel 101 and the second side panel 102 form a receiving space around the base 6, and the first side panel 101 and the second side panel 102 are foldably connected to the base 6. The first side panel 101 may be the side panel 101 in this embodiment, so that when folded onto the base 6, the height of the first side panel 101 may be reduced, making it easier to fold. In other embodiments, the second side panel 102 of the container 100 may also be the side panel 101 in this example.

[0060] like Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5 As shown, the side plate 101 of the container 100 includes: a first plate body 2, a second plate body 3 and a third plate body 4. The first plate body 2 has a first limiting surface 20. The second plate body 3 is arranged with the first plate body 2 along the height direction of the side plate 101. The second plate body 3 has a main plate 31, and an extension plate 32 located on the side of the main plate 31 facing the first plate body 2, and the extension plate 32 is slidably connected to the first plate body 2 along the height direction of the side plate 101. The third plate body 4 is hingedly connected to the second plate body 3 by a hinge shaft 5, and the hinge shaft 5 extends along the horizontal length direction of the side plate 101. Among them, as Figure 4 and Figure 5 In the embodiment, the extension plate 32 slides along the first plate body 2 to the first position, at which time the side plate 101 is a short plate, the height of the side plate 101 is reduced, the third plate body 4 is turned over to abut against the first plate body 2, the third plate body 4 is attached to the outer surface of the first plate body 2, and the first plate body 2 and the third plate body 4 are positioned; Figure 1 and Figure 2The middle extension plate 32 slides along the first plate body 2 to the second position, the height of the side plate 101 increases, the third plate body 4 is flipped and abuts against the first limit surface 20, the first plate body 2 and the third plate body 4 are fixed, and the third plate body 4 is close to the extension plate 32. Specifically, when the side plate 101 is a short plate, the third plate body 4 is attached to the outer surface of the first plate body 2, the first plate body 2 and the third plate body 4 are abutted, the extension plate 32 will not slide down, the third plate body 4, the first plate body 2 and the second plate body 3 form an integral plate, and the third plate body 4 will not protrude outside. When the side panel 101 is a high panel, the first panel 2 is pulled upward, the extension panel 32 slides out a portion of the first panel 2, and the third panel 4 is flipped over so that the third panel 4 is abutted against the first limiting surface 20. At this time, one end of the third panel 4 is positioned by the extension panel 32 in the height direction, and the other end is positioned by the first limiting surface 20, that is, the third panel 4 is positioned, and the extension panel 32 will not slide down anymore, so that the side panel 101 is a stable high panel, and the third panel 4 will not protrude out.

[0061] It is not difficult to find from the above contents that, since the extension plate 32 can slide along the first plate body 2, when the side plate 101 needs to be a short plate, the extension plate 32 is allowed to slide down to shorten the distance between the main plate 31 and the first plate body 2, and then the third plate body 4 is turned over to be in contact with the outer surface of the first plate body 2. At this time, the third plate body 4 is close to the first plate body 2, and the second plate body 3 located above the first plate body 2 forms a short plate. When a high plate is needed, the second plate body 3 can be pulled to allow the extension plate 32 to slide up to the second position, and then the third plate body 4 is turned over to be against the first limiting surface 20. At this time, the third plate body 4 plays a limiting role and is supported between the main plate 31 and the first plate body 2. The extension plate 32 cannot slide down again, thereby forming a high plate. When the side plate 101 forms two types of plates, a high plate and a short plate, the side plate 101 does not need to be folded in half, and the thickness of the side plate 101 is not increased.

[0062] Furthermore, if Figure 2 and Figure 3 As shown, the first plate body 2 has a first plate portion 21 and a second plate portion 22 arranged opposite to each other in the thickness direction of the side plate 101, and the first plate portion 21 and the second plate portion 22 are separated to form a channel 23. The extension plate 32 has an insertion portion 321 inserted into the channel 23, and the third plate body 4 is arranged on the side of the insertion portion 321 facing the first plate body. With the channel 23, in order to ensure the strength of the side plate 101, the insertion portion 321 can have a plurality of portions arranged in the thickness direction of the side plate 101.

[0063] In addition, if Figure 2 and Figure 3 As shown, the extension plate 32 also has a back plate portion 322 separated from the insertion portion 321 along the thickness direction of the side plate 101, and the second layer plate portion 22 is inserted between the insertion portion 321 and the back plate portion 322. Thus, the strength and stability of the side plate 101 are ensured.

[0064] Furthermore, if Figure 2 As shown, the first limiting surface 20 is located on the top surface of the first layer plate portion 21. Therefore, when the extension plate 32 slides along the first plate body 2 to the second position, that is, when the side plate 101 is a high plate, the third plate body 4 abuts against the top surface of the first layer plate portion 21, so that the extension plate 32 can no longer slide downward, forming a stable high plate. The third plate body 4 is turned over so that it does not abut against the top surface of the first layer plate portion 21, and the extension plate 32 slides downward to the first position, and the side plate is a low plate. In order to form a high plate, the second plate body can be manually pulled upward to allow the extension plate 32 to slide upward to the second position.

[0065] Specifically, Figure 5 and Figure 6 As shown, the first layer plate portion 21 has an upper plate 211 arranged along the height direction of the side plate 101 and a lower plate 212 connected to the upper plate 211. The outer surface of the upper plate 211 facing away from the second layer plate portion 22 is offset toward the channel 23 relative to the outer surface of the upper plate 211 facing away from the second layer plate portion 22 to form a recessed portion 213, and the third plate body 4 can be flipped around the hinge shaft 5 to the recessed portion 213, and the outer surface of the second layer plate portion 22 is facing the side inside the container 100. Therefore, when the extension plate 32 slides to the first position along the first plate body 2, that is, when the side plate 101 forms a short plate, the third side plate 101 is flipped to the recessed portion 213, the overall thickness of the side plate 101 in the short plate state can be guaranteed, and the third plate body 4 will not protrude outside. In addition, the extension plate 32 slides to the first position along the first plate body 2, and the upper plate and the third plate body 4 are against each other.

[0066] Furthermore, if Figure 5 and Figure 6 As shown, the bottom surface of the recessed portion 213 is the second limiting surface 214 , the extension plate 32 slides along the first plate body 2 to the first position, and the third plate body 4 flips over until the recessed portion 213 abuts against the second limiting surface 214 .

[0067] In addition, if Figure 5 and Figure 6 As shown, the sum of the thickness of the third plate body 4 and the thickness of the upper plate is less than or equal to the thickness of the lower plate.

[0068] In addition, if Figure 2 and Figure 3As shown, along the thickness direction of the side plate 101, the extension surface of the outer surface of the second plate body 3 in the height direction protrudes outside the insertion portion 321. That is to say, the outer surface of the second plate body 3 is the surface facing the outside of the container 100, and the extension surface of the surface in the height direction protrudes outside the insertion portion 321. When the third plate body 4 is flipped to extend along the height direction of the side plate 101, the outer surface of the third plate body 4 and the outer surface of the second plate body 3 can be close to the same plane, and the sum of the thickness of the third plate body 4 and the extension plate 32 along the sliding part of the first plate body 2 is equal to or approximately equal to the thickness of the second plate body 3. Therefore, when the side plate 101 is a high plate, the overall sense of the side plate 101 is stronger, and the thickness difference between the upper and lower sides of the side plate 101 will not be large due to the existence of the flippable third plate body 4, which also ensures the strength of the side plate 101 and better stability in use.

[0069] Furthermore, if Figure 5 and Figure 6 As shown, the extension surface of the outer surface of the second plate body 3 in the height direction is located in the same plane as the outer surface of the lower plate 212 .

[0070] In addition, if Figure 5 and Figure 6 As shown, the outer surface of the extension plate 32 is recessed inward to form a recessed position 323 for installing the hinge shaft 5, and the top end of the third plate body 4 is sleeved on the hinge shaft 5 and is located in the recessed position 323. The recessed position 323 is located in the area near the top of the extension plate 32, that is, the hinge shaft 5 is located in the area near the top of the extension plate 32, and the top end of the extension plate 32 extends outward from the container 100 to cover the hinge shaft 5 to support the second plate body 3, and the third side plate 101 is turned downward to abut against the first limiting surface 20 to achieve positioning. Therefore, the outer surface of the side plate 101 has a better overall sense, there will not be too many protruding areas, and the side plate 101 is more solid as a whole and has better stability.

[0071] Further, the extension plate 32 and the main plate 31 are two independent parts, and the two independent parts are fixedly connected together to form the second plate body 3, and can be connected together by gluing or inserting. In other embodiments, the extension plate 32 and the main plate 31 can be an integral part.

[0072] In this example, the outer surfaces of the first layer plate portion 21, the first plate body 2 and the second plate body 3 may be surfaces located outside the container 100. Of course, when the side plate 101 is installed on the base 6, the third plate body 4 may be placed on the side facing the inside of the container 100 as required.

[0073] In the embodiment of the other side panel, the structure of the side panel is substantially the same as that of the above embodiment, with the main difference being that the third plate body 4 in the side panel involved in the above embodiment is hinged to the second plate body 3, and when the first side panel forms a high panel, the third plate body 4 is flipped downward to counteract the first plate body 2, while the third plate body 4 in the other side panel may also be hinged to the first plate body 2 through a hinge axis, and when the side panel forms a high panel, the third plate body 4 is flipped upward to be positioned with the second plate body 3.

[0074] The third plate 4 and the second plate 3 are positioned, and the third plate 4 and the second plate 3 can be clamped together by protrusions and depressions, or by adding a fixing buckle, or a second limiting surface can be set on the second plate 3, so that the top surface of the third plate 3 after flipping upwards is against the second limiting surface, and the third plate 4 is pressed down by the gravity of the second plate 3 to achieve the positioning of the third plate 4 and the second plate 3. Specifically, the second limiting surface can be set on the bottom surface of the main plate 31, that is, the bottom surface of the part of the main plate 31 protruding outside the extension plate 32, so that the third plate 4 and the second plate 3 can be positioned. Figure 6 For example, the top surface of the recessed position 323. A protrusion can be provided on the side of the third plate body 4 away from the hinged connection with the first plate body (i.e., the top surface of the third plate body after being flipped upward), and a notch can be provided on the second limiting surface, so that the protrusion can be inserted into the notch, and the third plate body 4 and the second plate body 3 are further positioned. When the side plate forms a short plate, the third plate body 4 can be flipped downward to the outer surface of the first plate body (similar to Figure 5 The middle area, only the third plate body 4 is hinged to the top of the first plate body 2), and the extension plate 32 slides down to the first position. In this side plate, the first plate body 2 includes a first layer plate portion 21 and a second layer plate portion 22, the first layer plate portion 21 has an upper plate 211 and a lower plate 212 connected to the upper plate 211, and the structure of the recessed portion 213 is the same as the side plate structure in the above embodiment, which will not be described in detail here. The matching structure of the extension plate and the first plate body in sliding connection is the same as the side plate structure in the above embodiment, which will not be described in detail here.

[0075] Furthermore, the sum of the thickness of the third plate body 4 and the thickness of the upper plate 211 is less than or equal to the thickness of the lower plate 212 .

[0076] Since the extension plate can slide along the first plate body, when the side plate needs to be a short plate, the extension plate is allowed to slide down to shorten the distance between the main plate and the first plate body, and then the third plate body is flipped over to be in contact with the outer surface of the first plate body. At this time, the third plate body is close to the first plate body, and the second plate body located above the first plate body forms a short plate. When a high plate is needed, the second plate body can be pulled to allow the extension plate to slide up to the second position, and then the third plate body is flipped over to be positioned with the second plate body. At this time, the third plate body plays a limiting role and is supported between the main plate and the first plate body. The extension plate cannot slide down any further, thereby forming a high plate. When the side plate forms two types of plate bodies, the high plate and the short plate, the side plate does not need to be folded in half, and the thickness of the side plate is not increased.

[0077] Another embodiment of the utility model also relates to a container.
