DETAILED DESCRIPTION

[0053] The present subject matter pertains to improved approaches for a screw-free, integrated hinge structure for adjacent plastic boards. Embodiments of the present subject matter are discussed below with reference to FIGS. 1-23.

[0054] In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the present subject matter. It will be apparent, however, to one skilled in the art that the present subject matter may be practiced without some of these specific details. In addition, the following description provides examples, and the accompanying drawings show various examples for the purposes of illustration. Moreover, these examples should not be construed in a limiting sense as they are merely intended to provide examples of embodiments of the subject matter rather than to provide an exhaustive list of all possible implementations. In other instances, well-known structures and devices are shown in block diagram form in order to avoid obscuring the details of the disclosed features of various described embodiments.

[0055] As shown in FIGS. 1 to 5, along the direction indicated by arrow D in FIG. 1, the storage box of this embodiment is a square box, including a bottom board 1, a front board 2, a rear board 3, and a left board 4, a right board 5 and cover board 6. According to some embodiments, the front board 2, the rear board 3, the left board 4, the right board 5 and the cover board 6 can be blow-molded boards that are integrally formed in one-piece, and the bottom board 1 can be an injection-molded board that is integrally formed in one-piece.

[0056] According to some embodiments, the bottom board 1, the front board 2, the rear board 3, the left board 4 and the right board 5 can adopt screw-free, plug-in coupling structures with their respective adjacent boards, which is convenient for installation and disassembly. The screw-free, plug-in coupling structure can adopt strip-shaped ribs and strip-shaped grooves that can be interlocked with each other.

[0057] The cover board 6 can be pivotably or rotatably connected to the rear board 3. A spring 9 connected to the cover board 6 can be installed on both the left board 4 and the right board 5. Spring 9 can enable the cover board 6 to open and close more easily.

[0058] According to some embodiments, a transverse support rod 73 can be installed on the front edge of the cover board 6. A lock 64 can be installed on the transverse support rod 73. The transverse support rod 73 can strengthen the cover board 6 and prevent it from bending. A lock hole 21 can be installed at the corresponding position of the front board 2. When the storage box is closed, the lock catch 64 can pass through the lock hole 21.

[0059] According to some embodiments, a vertical partition board 7 can be arranged inside the storage box. The vertical partition board 7 can divide the storage box into two storage areas. The bottom of the vertical partition board 7 can be fixed on the bottom board 1. The front and rear sides of the vertical partition board 7 can be respectively mated with the front board 2 and the rear board 3. In particular, the vertical partition board 7 can have pins that can be inserted into corresponding sockets provided the front board 2 and the rear board 3. As such, connection structures, e.g., pins and sockets, are conventional, without additional descriptions needed.

[0060] According to some embodiments, the inner bottom surface of the bottom board 1 can have protruding limiting ribs 11 that are distributed in the left and right directions. The bottom of the vertical partition board 7 can have one or more limiting grooves 71 to couple with the limiting ribs 11. The inner side of the cover board 6 can have strip-shaped ribs 613 corresponding to the vertical partition board 7. When the cover board 6 is closed, the strip-shaped ribs 613 can abut against the vertical partition board 7. As such, the vertical partition board 7 can support the cover board 6 to increase the load-bearing capacity of the cover board 6 and to enhance the stability of the storage box.

[0061] According to some embodiments, the vertical partition board 7 can comprise two small partition boards that can be assembled together. According to some embodiments, multiple vertical partition boards 7 can be used not only to strengthen the storage box but also to provide more organized storage space.

[0062] According to some embodiments, as shown in FIGS. 4 and 21, one or more fixation hole 12 can be presented in the bottom board 1. The storage box can be fastened to the ground by screws via fixation hole 12.

[0063] According to some embodiments, the storage box can have waterproof features. The cover board 6 can have an arched structure with an uneven top. For example, cover board 6 can have a high rear portion and a low front portion or a high central portion and a low side portion. When the cover board 6 is closed, the uneven top can allow water to flow away from the box and not flow into the box.

[0064] As shown in FIGS. 6 to 11, according to some embodiments, an embedded groove hinge 63 can be formed in the inner side of the cover board 6. The embedded groove hinge 63 can have two openings respectively located on opposite sides of the cover board 6, thus dividing the cover board 6 into rotatable upper folding portion 61 and lower folding portion 62. The lower turning portion 62 can be detachably connected to the rear board 3 to form a full rear board of the plastic storage box.

[0065] Furthermore, the full rear board is composed of an upper part and a lower part, whereas the upper part is the lower turning portion 62 and the lower part is the rear panel 3. The rear board construction is novel and unique. According to some embodiments, the two-part panel can be adopted by the cover board, instead of the rear board. Accordingly, an embedded groove hinge on the rear board can divide it into two turning portions as described herein.

[0066] When the cover board 6 is coupled to the rear board 3, the lower folding portion 62 is mated with the rear board 3 so that the upper folding portion 61 is pivotable or rotatable in relation to the full rear board by the embedded groove hinge 63. The embedded groove hinge 63 can eliminate the need for a traditional hinge. It has a simple structure that is easy to assemble. Without any metal components, the integrated hinge structure has a relatively low manufacturing cost.

[0067] As shown in FIGS. 12 and 13, the lower turning portion 62 of the cover board 6 and the rear board 3 can adopt a plug-in coupling to form a detachable connection. The specific structure can be: first pins 621 and second sockets 622 disposed on the lower side of the lower turning portion 62, and first sockets 31 and second pins 32 disposed on the upper side of the rear board 3. The first pins 621 can be inserted into the corresponding first sockets 31, and the second pins 32 can be inserted into the corresponding second sockets 622.

[0068] According to some embodiments, the first sockets 31 and/or the second sockets 622 can further comprise ribs 625. The first pins 621 and/or the second pins 32 can further comprise grooves 33. The ribs 625 can be snapped into the corresponding grooves 33 when the lower turning portion 62 is connected to the rear board 3 to form the full rear board.

[0069] According to some embodiments, the inner side of the upper turning portion 61 can have an upper inclined surface 611 connected with one side of the embedded groove hinge 63. The inner side of the lower turning portion 62 can have a lower inclined surface 623 connected with the other side of the embedded groove hinge 63.

[0070] According to some embodiments, the upper inclined surface 611 can abut against the lower inclined surface 623 to prevent the upper turning portion 61 and the lower turning portion 62 from collapsing into each other when the upper turning portion 61 and the lower turning portion 62 are perpendicular to each other.

[0071] According to some embodiments, the inner surface of the upper turning portion 61 can further comprise inwardly extending stopper stripes 612. The inner surface of the lower turning portion 62 can further comprise stopper bars 624.

[0072] According to some embodiments, the inwardly extending stopper stripes 612 can abut against the stopper bars 624 to prevent the upper turning portion 61 and the lower turning portion 62 from collapsing into each other when the upper turning portion 61 and the lower turning portion 62 are perpendicular to each other.

[0073] As shown in FIGS. 14-19, when the storage box is in the packaged state, the lower turning portion 62 of the cover board 6 can be installed on the rear side of the bottom board 1, and the upper turning portion 61 of the cover board 6 can be folded to the top of the bottom board 1. The package structure comprises an installation cavity 10 formed between the upper turning portion 61, the lower turning portion 62, the bottom board 1, and the front side board 2. The rear board 3, the left board 4, and the right board 5 can be stacked in the installation cavity 10 in the storage box packaging state.

[0074] As shown in FIGS. 20 and 21, limiting ribs 11 can be provided between the vertical partition board 7 and the bottom board 1. The limiting ribs 11 can be distributed at intervals from front to back. As shown in FIG. 5, second limiting slot 72 can be formed on the side of the vertical partition board 7. During the storage box packaging state, the limiting ribs 11 can be locked into the second limiting slot 72, thereby locking the vertical partition board 7 on the bottom board 1. It can prevent the vertical partition board 7 from moving forward and backward during transportation.

[0075] As shown in FIG. 21, a limit element can be provided between the lower turning portion 62 of the cover board 6 and the bottom board 1. It can be sockets 13 located on the bottom board 1, and first pins 621 located on the lower turning portion 62 of the cover board 6. As shown in FIG. 12, the first pins 621 can insert into the corresponding sockets 13 during the storage packaging state.

[0076] As shown in FIG. 22, a limiting element can be provided for the left board 4, the right board 5, the lower turning portion 62 of the cover board 6. It can be lateral limiting grooves 626 provided on the inner side wall of the lower turning portion 62 and water resisting stripes 8 provided on the left board 4 and right board 5. As shown in FIG. 3, when the storage box is packed, the water resisting stripes 8 are embedded in the corresponding lateral limiting grooves 626. the left board 4 and the right board 5 can be placed horizontally.

[0077] As shown in FIGS. 15 and 16, the front board 2 can be arranged horizontally. As shown in FIG. 3, the top of the front board 2 can have a water-retaining strip 8 that can abut the lock 64 on the transverse support rod 73, meaning the abutted parts would limit the rotation of the upper turning portion 61. Furthermore, in the package state, referring to FIGS. 9 and 10, the upper inclined surface 611 can abut against the lower inclined surface 623, the inwardly extending stopper stripes (612) can abut against the stopper bars 624. This would prevent the upper turning portion 61 of the cover board 6 from further inward turning.

[0078] As shown in FIG. 23, the front board 2, the rear board 3, the left board 4, the right board 5 and the cover board 6 of the storage box can be blow-molded panels with touchpoints on the inner surface. Such touchpoints can enhance the structural strength of the storage box.
