Description

Technical Field

[0001] This application relates to the field of folding storage boxes, and more particularly to a folding box. Background Technology

[0002] A folding case is a portable storage tool suitable for in-car storage and outdoor picnics. It features foldable storage, waterproof and easy cleaning, and the ability to neatly store small items. When unfolded, it can hold picnic tableware, snacks and other items. When folded, it can be easily stored in the trunk gap, combining practicality and portability.

[0003] In related technologies, Chinese Patent Publication No. CN219044486U discloses a folding box, which includes an upper cover, a lower cover, and side panels. The upper cover, lower cover, and side panels enclose a storage cavity for placing objects. The side panels include two opposing first side panels and two opposing second side panels. The first side panels are rotatably connected to the upper cover, and the two ends of the second side panels are rotatably connected to the upper cover and the lower cover, respectively. Force-applying holes are provided on the side walls of the first side panels. When a user needs to move the folding box, they can easily apply force through these holes to facilitate movement.

[0004] Regarding the aforementioned technologies, the inventors believe that when it is inconvenient for users to carry the folding box with both hands, force can only be applied to the folding box through the force application hole on the side wall of one of the first side panels. At this time, the folding box is in a tilted state, and the items stacked inside the folding box may slide or tip over, or even fall out of the folding box from the force application hole on the other side. There is still room for improvement. Utility Model Content

[0005] To address the issue that when a user carries the aforementioned folding box with one hand, the box is tilted, and the items inside may slide or tip over, or even fall out of the box through the force application hole on the other side, this application provides a folding box.

[0006] The folding case provided in this application adopts the following technical solution:

[0007] A folding case includes a case body and a cover plate mounted on the case body. The cover plate is provided with a first locking component for fixing the cover plate to the case body. The cover plate is also provided with a handle for a user to apply force with one hand.

[0008] By adopting the above technical solution, when users need to carry the folding box with one hand, they can apply force through the handle. Compared with applying force through the force hole, the handle can keep the folding box in a more stable state during the carrying process, effectively reducing the risk of items inside the box sliding, tipping over, or even falling out of the force hole, and improving the convenience of users carrying the folding box with one hand.

[0009] Optionally, the main body of the box includes a bottom plate, a locking frame, and four side plates rotatably connected to the bottom plate. The four side plates and the bottom plate work together to form a storage cavity for stacking items. The side of each of the four side plates away from the bottom plate is embedded in the locking frame.

[0010] By adopting the above technical solution, the combination structure of the bottom plate, locking frame and side plate makes the assembly and disassembly of the main body of the box more convenient. When storage is required, the side plate can be rotated and folded around the bottom plate to reduce the space occupied. When unfolded, the side plate and the bottom plate cooperate to form a storage cavity, which is convenient for stacking items. The locking frame can play a certain role in limiting and reinforcing the side plate, enhancing the structural stability of the main body of the box.

[0011] Optionally, the first locking component includes sliding blocks that correspond one-to-one with the four side plates. The cover plate is provided with a first mounting groove for mounting the sliding blocks. The locking frame is provided with a clearance hole. The side plate is integrally provided with a side edge. When the sliding block slides to the side closer to the side plate, the sliding block passes through the clearance hole and abuts against the side edge near the bottom plate.

[0012] By adopting the above technical solution, when the sliding block slides to the side closer to the side plate, it can pass through the clearance hole and abut against the side edge, thereby fixing the side plate and the cover plate together, preventing the cover plate from opening accidentally, and ensuring the safety of the items in the storage cavity.

[0013] Optionally, the first locking component further includes an elastic block integrally disposed on the sliding block, and a locking block integrally disposed on the groove wall of the first mounting groove to lock the sliding block in cooperation with the elastic block.

[0014] By adopting the above technical solution, when the sliding block slides to the appropriate position, the elastic block can abut against the side of the locking block near the side plate, preventing the sliding block from moving away from the side plate, and further enhancing the stability of the locking cover plate and the main body of the box of the first locking component.

[0015] Optionally, the sliding block is integrally provided with a limiting block extending outside the first mounting groove.

[0016] By adopting the above technical solution, the limiting block can prevent the sliding block from sliding into the storage cavity from the side away from the side plate of the first mounting groove, thus improving the convenience of the sliding block being embedded in the first mounting groove; on the other hand, the user can push or pull the sliding block by directly contacting the limiting block, thus improving the convenience of operation.

[0017] Optionally, at least one of the side panels is provided with a retrieval opening and a retrieval door rotatably connected to the side wall of the retrieval opening.

[0018] By adopting the above technical solution, the design of the retrieval opening and retrieval door allows users to directly retrieve or place items from the side without opening the cover, increasing the convenience of use.

[0019] Optionally, the side plate is provided with a groove that communicates with the retrieval port.

[0020] By adopting the above technical solution, the groove is set on the side plate and connected to the retrieval port, providing a force point for the user. The user can hook the groove with their fingers to open the retrieval door more easily, improving the convenience of using the retrieval door.

[0021] Optionally, a second mounting groove is provided on the side wall of the retrieval opening, and a mounting post is integrally provided on the groove wall of the second mounting groove. An embedding block is integrally provided on the retrieval door and embedded in the second mounting groove. The embedding block is provided with mounting holes adapted to the mounting post.

[0022] By adopting the above technical solution, when the embedding block is embedded in the second mounting groove, the installation position of the retrieval door can be initially positioned to avoid displacement during installation; and the mounting post is inserted into the matching mounting hole, which not only stably connects the retrieval door to the side wall of the retrieval opening, ensuring that the retrieval door can rotate smoothly around the mounting post to realize the opening and closing function, but also reduces the radial shaking during the rotation of the retrieval door and enhances the overall connection firmness.

[0023] Optionally, the end of the mounting post away from the groove wall of the second mounting groove is provided with a guide surface.

[0024] By adopting the above technical solution, when the mounting column is close to the mounting hole, the guide surface can reduce the frictional resistance between the mounting column and the embedded block through the inclined surface, guide the mounting column to quickly align and slide into the mounting hole, and improve the convenience of installing the retrieval door.

[0025] Optionally, the base plate is provided with reinforcing ribs.

[0026] By adopting the above technical solutions, the reinforcing ribs can enhance the strength and load-bearing capacity of the base plate. When placing heavy items, the base plate is less likely to deform, extending the service life of the folding box and better ensuring the structural stability of the main body of the box.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. When users need to carry the folding box with one hand, they can apply force through the handle to keep the folding box in a relatively stable state during the carrying process, which improves the convenience of users carrying the folding box with one hand;

[0029] 2. The sliding block slides towards the side panel and abuts against the side edge to achieve a fixed connection between the side panel and the cover, effectively preventing the cover from opening accidentally and ensuring the safety of items in the storage cavity;

[0030] 3. The elastic block abuts against the side of the locking block near the side plate to prevent the sliding block from moving away from the side plate, further enhancing the stability of the locking cover plate and the main body of the box of the first locking assembly.

[0041] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0042] This application discloses a folding box.

[0043] Reference Figure 1 The folding case includes a main body 1, a cover 2, and a first locking assembly 3. The cover 2 is installed on the main body 1 to seal the main body 1. The first locking assembly 3 is installed on the cover 2 to lock the cover 2.

[0044] Reference Figure 2 and Figure 3 The main body 1 of the container includes a base plate 11, four side plates 12, and a locking frame 13. The base plate 11 includes a base plate body 111 and four mounting portions 112 arranged circumferentially along the base plate body 111. The mounting portions 112 are integrally connected to the base plate body 111 for mounting the side plates 12. The four side plates 12 are hinged to the four mounting portions 112 one-to-one, and the base plate 11 and the four side plates 12 cooperate to form a storage cavity for stacking items. The locking frame 13 has locking grooves 131 for locking the four side plates 12 in their enclosed state, and the side of each side plate 12 away from the base plate 11 is embedded in the locking groove 131. To enhance the strength and load-bearing capacity of the base plate 11, reinforcing ribs 14 are fixedly connected to the base plate 11.

[0045] Reference Figure 4 and Figure 5The first locking component 3 includes sliding blocks 31 and elastic blocks 32 corresponding to the four side plates 12. The cover plate 2 has a first mounting groove 21 for mounting the sliding blocks 31. The groove walls of the first mounting groove 21, both near and away from the corresponding side plate 12, have first through holes 211. The sliding blocks 31 are embedded in the first mounting groove 21, with both ends of the sliding blocks 31 passing through the two first through holes 211 respectively. The elastic blocks 32 are integrally connected to the sliding blocks 31, and a locking block 212, which cooperates with the elastic blocks 32 to lock the sliding blocks 31, is integrally connected to the groove wall of the first mounting groove 21. Side flanges 121 are integrally connected to the side plates 12, and the locking frame 13 also has clearance holes 132. When the sliding block 31 is pushed to slide towards the side plate 12, the sliding block 31 passes through the clearance hole 132 and abuts against the side edge 121 to prevent the cover plate 2 from detaching from the side plate 12 and the locking frame 13. At this time, the elastic block 32 abuts against the locking block 212 on the side plate 12 to prevent the sliding block 31 from sliding away from the side plate 12 due to collision or shaking. In order to prevent the sliding block 31 from sliding into the storage cavity from the first through hole 211 away from the side plate 12, a limiting block 311 extending out of the first mounting groove 21 is also integrally connected to the sliding block 31.

[0046] Reference Figure 6 and Figure 7 At least one side plate 12 has a retrieval opening 122 and a retrieval door 123. In this embodiment, the example is described with one retrieval opening 122 and one retrieval door 123. The side wall of the retrieval opening 122 has several second mounting grooves 1221, which penetrate the side plate 12 along its thickness direction. Mounting posts 1222 are integrally connected to both sides of the second mounting groove 1221, and the end of the mounting post 1222 away from the groove wall of the second mounting groove 1221 also has a guide surface 1223. An embedded block 1231 corresponding to the second mounting groove 1221 is integrally connected to one side wall of the retrieval door 123. Each embedded block 1231 has a mounting hole 1232 adapted to the mounting post 1222. The embedding block 1231 is embedded in the second mounting groove 1221. When the mounting post 1222 approaches the mounting hole 1232, the guide surface 1223 can guide the mounting post 1222 to align and slide into the mounting hole 1232 through its inclined surface, so that the retrieval door 123 can be rotatably connected to the side wall of the retrieval opening 122. The side plate 12 also has a groove 124 communicating with the retrieval opening 122, so that the user can pull open the retrieval door 123 through the groove 124.

[0047] Reference Figure 8 and Figure 9To prevent items from falling out of the retrieval opening 122 due to accidental opening of the retrieval door 123, a second locking component 1233 is installed on the retrieval door 123. The second locking component 1233 includes two pins 12331. The retrieval door 123 has two third mounting slots 1234, each with a second through hole 1235 on its sidewall. The two pins 12331 are correspondingly fitted into the two third mounting slots 1234, with one end of each pin passing through the second through hole 1235. The sidewall of the retrieval opening 122 has a lock hole 1224 that matches the pins 12331. When the pins 12331 are pushed into the lock hole 1224, the retrieval door 123 is locked. The side of the pin 12331 away from the lock hole 1224 is also integrally connected with a pull ring 12332, so that the user can pull the pin 12331 out of the lock hole 1224.

[0048] Reference Figure 1 To facilitate user handling, a handle 22 is fixedly connected to the cover plate 2.

[0049] The implementation principle of a folding box according to an embodiment of this application is as follows: when the four side plates 12 are rotated to be perpendicular to the bottom plate 11, the locking frame 13 is fitted onto the four side plates 12, at which time the side plates 12 and the bottom plate 11 enclose a storage cavity; then the cover plate 2 is placed on the main body 1 of the box, and the sliding block 31 is pushed through the clearance hole 132 to abut against the side edge 121. At this time, the user can carry the folding box by the handle 22; when it is inconvenient to open the cover plate 2 of the folding box, the user can open the retrieval door 123 by pulling the latch 12331 to unlock it and take out the items from the retrieval opening 122.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
