Description

Technical Field

[0001] This utility model relates to the field of storage box technology, specifically to a folding box that is easy to store and assemble. Background Technology

[0002] Folding crates are tools designed for warehousing and logistics, featuring a foldable design for easy storage and transport. They are typically made of durable plastic. Key characteristics of folding crates include lightweight, small footprint, and easy assembly. When not in use, folding crates can be folded into a smaller volume, saving storage and transportation space. This design allows folding crates to significantly reduce warehousing costs when empty.

[0003] The authorization announcement number CN221915076U discloses a side-opening folding storage box with a handle. According to its instruction manual and drawings, the design allows the support part and part of the connecting part of the handle to slide outside the front and rear side panels, making it easier for the user to hold the support part and move the entire box. When there are no items in the box, the user first puts their hand into the first actuation hole and rotates the bottom plate to fit against the front side panel. Then, the left and right side panels are folded so that the protrusions engage with the positioning holes, thus completing the folding of the box. However, with this structure, the handle is located inside the box and needs to be pulled out each time it is used, which occupies some area inside the box and affects the box's capacity. Furthermore, after folding with this structure, there is still room for optimization of the overall thickness of the box. Summary of the Invention

[0004] This utility model mainly addresses the problems existing in the use of storage boxes, and invents a folding box that is easy to store and assemble. Since the height of the first mounting plates on the left and right sides is greater than the height of the second mounting plates on the front and rear sides, the front and rear second side plates are folded towards the surface of the supporting base plate, and then the left and right first side plates are folded towards the surface of the supporting base plate. After the second side plates and the first side plates are folded, they will not squeeze each other or interfere excessively. The outside of the first side plate is provided with a handle support protrusion, and the box handle can be rotatably connected to the handle support protrusion. The box handle can be used for leverage, and this design does not take up space inside the box.

[0005] The purpose of this invention is achieved through the following technical solution: a folding box that is easy to store and assemble, including a supporting base plate, the surface of the supporting base plate is provided with box side plates, each of the box side plates can be folded relative to the supporting base plate, at least two box side plates are provided with box handles on their side walls, the surface of the box side plates is detachably connected with a locking plate for restricting the folding of the box side plates, and the surface of the locking plate is provided with a first box cover.

[0006] Preferably, the surface of the supporting base plate is provided with a plurality of first mounting plates and second mounting plates of different heights, and each of the box side plates is rotatably connected to the surface of the first mounting plates and second mounting plates.

[0007] Preferably, the side panel of the housing includes several first side panels and second side panels of different heights. Each first side panel and second side panel has a pivot support boss at its bottom. Each pivot support boss has a pivot groove inside. Each first side panel and second side panel can be rotatably connected to a first mounting plate and a second mounting plate through the pivot groove.

[0008] Preferably, at least one of the second side panels has a box material receiving port on its surface, and a box door panel is rotatably connected inside the box material receiving port. The box material receiving port is provided with a plurality of first limiting buckles, and the end of each box door panel is detachably connected to the first limiting buckle.

[0009] Preferably, the first mounting plate and the second mounting plate are provided with a plurality of mounting plate grooves, each mounting plate groove is provided with a first rotating shaft inside, and each rotating shaft groove is rotatably connected to the first rotating shaft.

[0010] Preferably, the top of the first side plate and the second side plate are provided with a number of side plate protrusions, and the inside of the locking plate is provided with a number of locking grooves adapted to the side plate protrusions. Each side plate protrusion can be detachably locked inside the locking groove. This arrangement is to achieve the limiting and locking of the locking plate on the first side plate and the second side plate.

[0011] Preferably, the inside of the first lid is provided with a lid groove that is adapted to the locking plate. The lid groove can be detachably locked onto the surface of the locking plate. This arrangement uses the first lid to prevent items inside the box from falling out.

[0012] Preferably, the first side plate and the second side plate are staggered and connected to the surface of the supporting base plate. Each first side plate is provided with a handle support boss on its exterior. Each of the box handles is rotatably connected to the handle support boss. This arrangement is to reduce the space occupied by the box handles inside the box.

[0013] Preferably, the bottom of the supporting base plate is detachably connected to several box rollers. This arrangement is for the purpose of sliding transport when moving the entire box, which saves effort.

[0014] Compared with the prior art, this utility model has the following beneficial effects: 1. Since the height of the first mounting plates on the left and right sides is greater than the height of the second mounting plates on the front and rear sides, the second side plates at the front and rear are folded towards the surface of the supporting base plate, and then the first side plates on the left and right sides are folded towards the surface of the supporting base plate. Finally, the second side plates and the first side plates will not squeeze or interfere with each other too much after folding, which facilitates the subsequent storage of the box; 2. Since frequent opening of the first box lid will not only affect the tightness between the first box lid and the locking plate, but will also have a certain probability of affecting the locking plate's limiting and locking of the first and second side plates, under normal circumstances, one or two box doors can be opened for taking out and putting in, which increases the convenience of using the entire folding box; 3. The outside of the first side plate is provided with a handle support protrusion, and the box handle can be rotatably connected to the handle support protrusion; when the user moves the entire box, they can use the box handle for leverage, and this design will not occupy the volume inside the box, making it convenient for the user to stack items inside the box.

[0022] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0023] like Figures 1 to 6As shown, a folding case that is easy to store and assemble includes a supporting base plate 1, with several case wheels 7 detachably connected to the bottom of the supporting base plate 1. The surface of the supporting base plate 1 is provided with case side plates 2, each of which can be folded relative to the supporting base plate 1. Specifically, the surface of the supporting base plate 1 is provided with several first mounting plates 11 and second mounting plates 12 of different heights, and each case side plate 2 is rotatably connected to the surfaces of the first mounting plates 11 and second mounting plates 12. Each case side plate 2 includes several first side plates 21 and second side plates 22 of different heights. The bottom of each first side plate 21 and second side plate 22 is provided with a pivot support boss 23, and the interior of each pivot support boss 23 is provided with a pivot groove 231. Each first side plate 21 and second side plate 22 is rotatably connected to the first mounting plate 11 and the second mounting plate 12 respectively through the pivot groove 231. It should be noted that the first side plates 21 and second side plates 22 are alternately connected to the surface of the supporting base plate 1. To limit the rotation angle of the first side plate 21 and the second side plate 22, the first mounting plate 11 and the second mounting plate 12 are also provided with a number of plate grooves 13. Each plate groove 13 is provided with a first rotating shaft 14 inside. Each rotating shaft groove 231 is rotatably connected to the first rotating shaft 14. With this arrangement, since the height of the first mounting plate 11 on the left and right sides is greater than the height of the second mounting plate 12 on the front and rear sides, the front and rear second side plates 22 can be folded towards the surface of the supporting base plate 1 first, and then the left and right first side plates 21 can be folded towards the surface of the supporting base plate 1. Finally, the second side plates 22 and the first side plates 21 will not squeeze or interfere with each other too much after folding, which facilitates the subsequent storage of the box.

[0024] In this embodiment, at least two side panels 2 of the box are provided with box handles 3 on their side walls. Specifically, each of the first side panels 21 has a handle support protrusion 15 on its exterior, and each box handle 3 is rotatably connected to the handle support protrusion 15. With this arrangement, when the user moves the entire box, they can use the box handles 3 for leverage, and this design does not occupy the volume inside the box, making it convenient for the user to stack items inside the box. The surface of the box side panel 2 is detachably connected to a locking plate 4 for restricting the folding of the box side panel 2, and the surface of the locking plate 4 is provided with a first box cover 5. Both the locking plate 4 and the first box cover 5 are made of deformable plastic material. Specifically, the top of the first side panel 21 and the second side panel 22 are provided with several side panel protrusions 24, and the inside of the locking plate 4 is provided with several locking grooves 41 adapted to the side panel protrusions 24, and each side panel protrusion 24 is detachably locked inside the locking groove 41. This detachable design is achieved through the deformability and interference fit between the locking groove 41 and the side plate protrusion 24. The interior of the first lid 5 has a lid groove 51 adapted to the locking plate 4. The lid groove 51 can be detachably engaged with the surface of the locking plate 4. This detachable design is achieved through the deformability and interference fit between the lid groove 51 and the locking plate 4. The locking groove 41 on the locking plate 4 engages each side plate protrusion 24, thus limiting the position of the first side plate 21 and the second side plate 22 and preventing changes in their angles. The detachable connection between the lid groove 51 inside the first lid 5 and the locking plate 4 allows for the retrieval and placement of items within the entire box.

[0025] In this embodiment, at least one of the second side panels 22 has a box opening 221 on its surface. A box door panel 6 is rotatably connected inside the box opening 221. The box opening 221 contains several first limiting buckles 222. The end of each box door panel 6 is detachably connected to a first limiting buckle 222. This detachable design is achieved through the deformability of the groove inside the box door panel 6 and the first limiting buckle 222, combined with an interference fit. Since frequent opening of the first box cover 5 not only affects the locking tightness between the first box cover 5 and the locking plate 4, but also has a certain probability of affecting the locking plate 4's limiting and locking of the first side panel 21 and the second side panel 22, under normal circumstances, one or two box door panels 6 can be opened for retrieval and loading / unloading, increasing the overall convenience of using the folding box.

[0026] Working principle and usage of this utility model:

[0027] When folding: First, push the first lid 5 upwards until the lid groove 51 inside the first lid 5 disengages from the locking plate 4. Then, push the locking plate 4 upwards until the locking groove 41 on the locking plate 4 disengages from each side plate protrusion 24. At this time, the locking plate 4 loses its limiting and locking of the first side plate 21 and the second side plate 22. Next, fold the front and rear second side plates 22 toward the surface of the supporting base plate 1. Then, fold the left and right first side plates 21 toward the surface of the supporting base plate 1. Finally, the second side plates 22 and the first side plates 21 will not squeeze or interfere with each other too much after folding, which facilitates the subsequent storage of the box.

[0028] When unfolding: First, fold the two first side panels 21 to the side, then fold the front and rear second side panels 22 upward. During the folding process, the pivot groove 231 rotates relative to the first pivot 14, and the pivot groove 231 limits the maximum angle of the first side panels 21 and the second side panels 22 after unfolding to 90 degrees. After folding, the locking groove 41 on the locking plate 4 locks each side panel protrusion 24 to limit the first side panel 21 and the second side panel 22. Then, the box cover groove 51 inside the first box cover 5 cooperates with the locking plate 4 to complete the unfolding of the entire folding box.
