Technical Field

[0001] This utility model relates to the field of packaging boxes, specifically a hinged plywood packaging box. Background Technology

[0002] Hinged plywood crates are reusable transport containers made primarily of plywood, with the lid and body connected by metal hinges. They are widely used in the logistics and transportation of industrial equipment, precision instruments, and automotive parts.

[0003] According to Chinese Patent No. CN218464128U, a reusable packaging box is disclosed. This utility model can assemble the side panels, top panel and bottom panel into a cubic packaging box by means of multiple sets of hinges. Finally, the top panel and side panels are fixedly connected by multiple sets of fixing screws to ensure the stability of the packaging box after assembly. Since the packaging box is detachable and assembleable, it is convenient for staff to store it when it is not in use, and it does not occupy a large storage space, thus meeting people's usage needs.

[0004] Regarding the aforementioned patent content, multiple sets of hinges are provided to assemble the side panels, top panel, and bottom panel into a packaging box. However, since the hinges are located outside the assembled packaging box, external objects are very likely to collide with the hinges during the handling or transportation of the packaging box. If the hinges are subjected to external impact for a long time, they are prone to breakage and damage, which in turn affects the stability of the packaging box and reduces the protective effect on the hinges. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a hinged plywood packaging box to solve the technical problem of poor protection of the hinge.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hinged plywood packaging box, comprising a bottom plate, two side plates and two front panels respectively mounted on the top of the bottom plate via a first hinge, fixing seats fixed on both sides of the back of one front panel and both sides of the outer surface of the other front panel, and the top of the fixing seats respectively having a first slot and a second slot, a first reinforcing plate inserted between every two first slots, and a second reinforcing plate inserted between every two second slots, a locking bolt extending into the first reinforcing plate being threadedly connected to one side of each of the two side plates, a sliding groove being provided on the upper side of one side plate and both sides of the bottom plate, a sliding seat being provided inside the sliding groove, a protective cover being installed between two sliding seats, and a protective plate being installed on one side of the other sliding seat.

[0007] By adopting the above technical solution, when the locking bolt is screwed into the first reinforcing plate, the first reinforcing plate can be locked and limited to prevent it from moving, thereby improving the stability of the first reinforcing plate.

[0008] Furthermore, four threaded holes are provided on one side of the inner side of the slide, and a fastening bolt extending into one of the threaded holes is threadedly connected to one side of the slide block.

[0009] By adopting the above technical solution, when the fastening bolt is screwed into the corresponding threaded hole, the slide can be locked and limited, thereby fixing the slide.

[0010] Furthermore, a buffer pad is installed on one side of both the protective cover and the protective plate, and multiple anti-collision strips are installed on one side of the side plate. Both the anti-collision strips and the buffer pads are made of rubber material.

[0011] By adopting the above technical solutions, the setting of buffer pads can improve the protective performance of protective covers and protective plates, while the setting of anti-collision strips can improve the anti-collision performance of packaging boxes.

[0012] Furthermore, a top plate is mounted on the top of one of the side plates via a second hinge, and a first sealing gasket is mounted on the bottom of the top plate.

[0013] By adopting the above technical solution, the setting of the first sealing gasket can improve the sealing performance between the top plate and the front and side plates.

[0014] Furthermore, the bottom of the panel and the side panel are each equipped with a second sealing gasket, and the bottom of the four second sealing gaskets is in contact with the top of the base plate, and the four second sealing gaskets are in contact with the sides of the side panel.

[0015] By adopting the above technical solution, the installation of the second sealing gasket can improve the sealing performance between the panel and side plate and the bottom plate.

[0016] Furthermore, one side of the fixing seat and one side of the first reinforcing plate are both attached to the side plate, and the second reinforcing plate is attached to the panel.

[0017] By adopting the above technical solution, the first reinforcing plate and the second reinforcing plate can strengthen the assembled packaging box and improve its stability.

[0018] Furthermore, the top of the second reinforcing plate contacts the first reinforcing plate, and the two first reinforcing plates and the two second reinforcing plates form a square structure.

[0019] By adopting the above technical solution, the first reinforcing plate can limit the second reinforcing plate and prevent the second reinforcing plate from moving upward at will.

[0020] Furthermore, both the protective cover and the protective plate are slidably connected to the slide groove via a slide block.

[0021] By adopting the above technical solution, when the protective cover and protective plate move, the slide block can be driven to slide inside the slide groove, thereby improving the stability of the protective cover and protective plate when they move.

[0022] Furthermore, the first hinge is located inside the protective cover, and the second hinge is located inside the protective plate.

[0023] By adopting the above technical solution, the protective cover can shield and protect the first hinge, while the protective plate can shield and protect the second hinge.

[0024] Furthermore, both the first reinforcing plate and the second reinforcing plate are detachably connected to the fixed base.

[0025] By adopting the above technical solution, it is convenient to install or disassemble the first reinforcing plate and the second reinforcing plate.

[0026] In summary, the present invention has the following main advantages:

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0039] The embodiments of this utility model will be described below based on its overall structure.

[0040] Example 1:

[0041] A hinged plywood packing box, such as Figures 1-8As shown, the system includes a base plate 1. Two side plates 3 and two front panels 22 are mounted on the top of the base plate 1 via a first hinge 2. The base plate 1, side plates 3, front panels 22, and top plate 5 are all made of plywood. Fixing seats 9 are fixed to both sides of the back of one front panel 22 and both sides of the outer surface of the other front panel 22. The top of each fixing seat 9 has a first slot 10 and a second slot 13. A first reinforcing plate 11 is inserted between every two first slots 10, and a second reinforcing plate 14 is inserted between every two second slots 13. Locking bolts 12 extending into the first reinforcing plate 11 are threaded onto one side of each of the two side plates 3. The fixing seats 9 contain… Both the first reinforcing plate 11 and the first reinforcing plate 11 are provided with screw holes. The locking bolt 12 is threadedly connected to the first reinforcing plate 11. The upper side of one side plate 3 and both sides of the bottom plate 1 are provided with sliding grooves 15. The sliding groove 15 is provided with a sliding seat 16. A protective cover 17 is installed between the two sliding seats 16. A protective plate 21 is installed on one side of the other sliding seat 16. When the locking bolt 12 is screwed into the first reinforcing plate 11, the first reinforcing plate 11 can be locked and limited to prevent the first reinforcing plate 11 from moving, thereby improving the stability of the first reinforcing plate 11. The outer surface and back of the first reinforcing plate 11 are in contact with the two panels 22 respectively.

[0042] See Figures 1-6 The slide groove 15 has four threaded holes 19 on one side. The slide block 16 is threadedly connected to one of the threaded holes 19 with a fastening bolt 18. When the fastening bolt 18 is screwed into the corresponding threaded hole 19, the slide block 16 can be locked and limited, thus fixing the slide block 16. The top of the second reinforcing plate 14 contacts the first reinforcing plate 11. The two first reinforcing plates 11 and the two second reinforcing plates 14 form a square structure. The first reinforcing plate 11 can limit the second reinforcing plate 14 to prevent the second reinforcing plate 14 from moving upward at will. The two sides of the second reinforcing plate 14 contact the two side plates 3 respectively. The protective cover 17 and the protective plate 21 are slidably connected to the slide groove 15 through the slide block 16. When the protective cover 17 and the protective plate 21 move, they can drive the slide block 16 to slide inside the slide groove 15, thereby improving the stability of the protective cover 17 and the protective plate 21 when they move. The top of one side plate 3 is mounted with a top plate 5 through a second hinge 4.

[0043] Specifically, the first hinge 2 is located inside the protective cover 17, and the second hinge 4 is located inside the protective plate 21. The protective cover 17 can shield and protect the first hinge 2, while the protective plate 21 can shield and protect the second hinge 4. The first reinforcing plate 11 and the second reinforcing plate 14 are both detachably connected to the fixing base 9, which facilitates the installation or removal of the first reinforcing plate 11 and the second reinforcing plate 14. A buffer pad 20 is installed on one side of the protective cover 17 and the protective plate 21, and multiple anti-collision strips 8 are installed on one side of the side plate 3. Both the anti-collision strips 8 and the buffer pads 20 are made of rubber material. The buffer pads 20 can improve the protective performance of the protective cover 17 and the protective plate 21, while the anti-collision strips 8 can improve the anti-collision performance of the packaging box. One side of the fixing base 9 and one side of the first reinforcing plate 11 are attached to the side plate 3, and the second reinforcing plate 14 is attached to the panel 22. The first reinforcing plate 11 and the second reinforcing plate 14 can reinforce the assembled packaging box and improve its stability.

[0044] Example 2:

[0045] Based on the above embodiment one, the following structure will be set to improve the sealing performance of the packaging box after assembly.

[0046] See Figure 2 and Figure 5 A first sealing gasket 6 is installed at the bottom of the top plate 5. The outer wall of the first sealing gasket 6 is in contact with the panel 22 and the side plate 3. The setting of the first sealing gasket 6 can improve the sealing between the top plate 5 and the panel 22 and the side plate 3. Second sealing gaskets 7 are installed at the bottom and both sides of the panel 22 and the side plate 3. The bottom of the four second sealing gaskets 7 is in contact with the top of the bottom plate 1, and the four second sealing gaskets 7 are in contact with the sides of the side plate 3. The setting of the second sealing gaskets 7 can improve the sealing between the panel 22 and the side plate 3 and the bottom plate 1.

[0047] The working principle of this utility model is as follows: First, before the packaging box is assembled, the slide 16 is located inside the lower part of the slide groove 15. When the packaging box needs to be assembled into a box body, the worker can rotate the two panels 22 upward in sequence so that the panels 22 are perpendicular to the bottom plate 1. Then, the two side plates 3 are rotated in sequence so that the side plates 3 are perpendicular to the bottom plate. At this time, one side of the side plate 3 is in contact with the fixing seat 9. Then, the worker first inserts the second reinforcing plate 14 into the second slot 13. After the two second reinforcing plates 14 are inserted, the first reinforcing plate 11 is inserted into the first slot 10. At this time, the top of the second reinforcing plate 14 is in contact with the first reinforcing plate 11. Then, the locking bolt 12 is screwed into the first reinforcing plate 11. This locks and limits the first reinforcing plate 11, preventing the first reinforcing plate 11 and the second reinforcing plate 14 from shifting. The top plate 5 is rotated via the second hinge 4 to reinforce the packaging box. Then, the bottom of the top plate 5 is rotated to fit against the side plate 3 and the front panel 22. Next, the protective cover 17 is pushed upward to slide the two slide blocks 16 to the inside of the slide groove 15. At this time, the protective cover 17 blocks the first hinge 2. Then, the fastening bolt 18 is screwed into the corresponding threaded hole 19 to lock and limit the protective cover 17. Next, the protective plate 21 is pushed upward to block the second hinge 4. Then, another fastening bolt 18 is screwed into the corresponding threaded hole 19 to limit the protective plate 21. At this time, the protective cover 17 can protect the first hinge 2, and the protective plate 21 can protect the second hinge 4, preventing external objects from directly colliding with the first hinge 2 or the second hinge 4 and causing damage to the hinges.
