[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] Reference Figure 1-7 As an embodiment of this utility model, a large-capacity injection-molded storage box that is easy to assemble is disclosed. Specifically, the storage box includes a bottom plate 1, two side plates 2 and two front panels 3.

[0032] The two side panels 2 are connected between the two panels 3 and together form a rectangular frame. A box cover 4 is rotatably connected above one of the panels 3, and the box cover 4 can cover the rectangular frame.

[0033] The side panel 2 and the front panel 3 are both connected to the base plate 1 through the first fastening structure 5, and the side panel 2 and the front panel 3 are connected through the second fastening structure 6.

[0034] It should be noted that in this embodiment, the base plate 1, side plate 2, front panel 3, and box cover 4 are all made of blow-molded parts, which can improve the ease of use by taking advantage of their good low weight.

[0035] In some embodiments, the first fastening structure 5 of the present invention includes a first slot 51 formed at the bottom of the side plate 2 and the panel 3, and a plurality of first locking blocks 52 formed around the base plate 1, wherein the first locking blocks 52 and the first slot 51 are inserted into each other.

[0036] Furthermore, the bottom of the side plate 2 and the panel 3 are provided with a plurality of first slots 53 that communicate with the first slot 51, and the bottom of the first card block 52 is formed with a first card protrusion 54, which engages with the first slot 53.

[0037] like Figure 4 , Figure 5 As shown, in this embodiment, when it is necessary to assemble the side panel 2 and the front panel 3, as follows: Figure 4 As shown, first place the two side plates 2 on both sides of the base plate 1, and then push them into the base plate 1 in the direction of the arrow in the figure. Align the first slot 51 on the side plate 2 with the first locking block 52 on the side of the base plate 1 and insert it. When the first locking block 52 is inserted into the inside of the first slot 51, the first locking protrusion 54 will be deformed until it pops out at the first locking groove 53 and engages with the first locking groove 53. In this way, the installation of the side plate 2 can be completed.

[0038] Similarly, Figure 5 As shown, assemble the two panels 3 from both sides and the base plate 1. Push the panels 3 onto the base plate 1 in the direction of the arrow in the figure. During this process, the panels 3 and the side panels 2 are combined through the second fastening structure 6 to complete the connection and assembly of the panels 3. After that, assemble the lid 4 to complete the assembly of the entire storage box. The operation is simple and convenient.

[0039] In some embodiments, the second fastening structure 6 of the present invention includes a second slot 61 formed on the inner end face of the panel 3, and a plurality of second locking blocks 62 are formed on both sides of the side plate 2, and the second locking blocks 62 and the second slot 61 are inserted into each other.

[0040] In addition, in this embodiment, the outer side of the panel 3 is provided with a plurality of second slots 63 that communicate with the second slot 61, and the end face of the second card block 62 is formed with a second card protrusion 64, which engages with the second slot 63.

[0041] Similarly, in this embodiment, the connection between panel 3 and side panel 2 is also a plug-in connection. As described above, when panel 3 is pushed to one side of bottom plate 1 for plugging, when the first slot 51 and the first locking block 52 are plugged in, the second slot 61 and the second locking block 62 between panel 3 and side panel 2 will also be locked in at the same time.

[0042] Similarly, when the first protrusion 54 and the first slot 53 engage, the second protrusion 64 will also engage and fix with the second slot 63. That is, when the panel 3 completes the insertion and assembly with the base plate 1, it will also complete the insertion and connection with the side plate 2 to achieve the purpose of convenient assembly.

[0043] It should be noted that in this embodiment, the first slot 51 has a plurality of first positioning pieces 55 distributed at intervals inside. The first card block 52 is inserted between two adjacent first positioning pieces 55. That is, in this embodiment, the first positioning pieces 55 are used to insert and position the first card block 52 and to provide lateral stops, which can effectively improve the assembly positioning accuracy between the side plate 2 and the bottom plate 1 and the stability after assembly.

[0044] Of course, in order to improve the assembly stability of panel 3, in this embodiment, the second slot 61 is provided with a number of second positioning pieces 65 at intervals, and the second locking block 62 is inserted between two adjacent second positioning pieces 65. Similarly, the cooperation of the second positioning pieces 65 and the second locking block 62 is used to achieve the positioning accuracy and assembly stability of panel 3 and base plate 1.

[0045] It should be noted that in this embodiment, a reinforcing groove 9 is provided at the upper end of the first card block 52 and the second card block 62. The reinforcing groove 9 is located above the first card protrusion 54 and the second card protrusion 64. The reinforcing groove 9 is used to reduce the strength of each card block at the corresponding card protrusion, so as to ensure that the card protrusion can smoothly generate extrusion deformation during the carding process.

[0046] In some embodiments, the box cover 4 of the present invention is rotatably connected to one of the panels 3 by a rotating member 7. The rotating member 7 can be configured as a hinge or as a rotating seat. The rotating seat is fixed on the panel 3 and rotatably connected to the box cover 4. A support assembly 8 is also provided between the box cover 4 and the side plate 2.

[0047] Based on the above embodiments, the support component 8 in this embodiment includes a lower fixing frame 81 fixed to the inner end of the side plate 2 and an upper fixing frame 82 fixed to the lower end of the box cover 4.

[0048] The end of the lower fixing frame 81 and the end of the upper fixing frame 82 are pinned together, wherein a pneumatic support rod 83 is pinned to the middle of the upper fixing frame 82, and the telescopic end of the pneumatic support rod 83 is pinned to the end of the lower fixing frame 81.

[0049] Specifically, in this embodiment, the lower fixing frame 81 can be fixed to the side plate 2 with bolts, and similarly, the upper fixing frame 82 can also be fixed to the box cover 4 with bolts. In addition, in order to ensure the stability of the support, there are two support components 8 in this embodiment, which are respectively connected between the two side plates 2 and the two sides of the box cover 4.

[0050] The design of the pneumatic support rod 83 enables convenient opening and support of the box cover 4, thereby improving the ease of operation of the box cover 4. Of course, the specific structure and principle of the pneumatic support rod 83 are common knowledge to those skilled in the art, and will not be elaborated here.

[0051] Of course, in order to ensure the storage and clearance of the pneumatic support rod 83 after the lid 4 is closed, the lower fixing frame 81 in this embodiment has a bending clearance position 84 in the middle to accommodate the pneumatic support rod 83.

[0052] In summary, the large-capacity injection-molded storage box of this utility model cleverly utilizes the snap-fit ​​structure between injection-molded parts, making the assembly process simple and quick. At the same time, with the telescopic function of the pneumatic support rod 83, the lid 4 can be easily opened and closed, greatly improving the convenience of operation. Furthermore, this storage box not only meets consumers' demand for large-capacity storage space, but also has good low-weight performance.

[0053] In addition, once the entire storage box is assembled, it can also be used as a stool to meet the multi-functionality of use. This effectively improves the convenience and practicality of the injection-molded storage box, making it adaptable to various different usage scenarios.

[0054] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
