[0025] Example

[0026] Reference Figs. 1-3 As an embodiment of the present utility model, a combined pulp molding packaging component is provided, comprising: a packaging unit 100 and a combination unit 200;

[0027] The packaging unit 100 includes a pulp board 101, a packaging cover 102 is fixedly connected to the bottom of the pulp board 101, and four evenly distributed support covers 103 are fixedly connected to the bottom of the pulp board 101. The tops of the packaging cover 102 and the four support covers 103 all penetrate the pulp board 101.

[0028] The assembly unit 200 includes multiple limiting holes 201 opened on the top of the pulp board 101. Rectangular grooves 202 are opened on the four side walls of the pulp board 101. Multiple rotating columns 203 are rotatably connected to the top of the pulp board 101. The bottom end of each rotating column 203 passes through the corresponding rectangular groove 202. A connecting plate 204 is fixedly connected to the bottom end of each rotating column 203. A circular opening is opened on the top of each connecting plate 204. A limiting plate 205 is fixedly connected to the top of each rotating column 203. A T-shaped rod 206 slides through the top of each limiting plate 205. A rubber stopper 207 is fixedly connected to the bottom end of each T-shaped rod 206.

[0029] The packaging cover 102 is used to store objects. Four support covers 103 are located near the four opposite corners of the bottom of the pulp board 101 to support the pulp board 101. The diameter of the bottom end of the T-shaped rod 206 is the same as the diameter of the limiting hole 201. The rubber plug 207 is hemispherical in shape and its diameter is larger than that of the limiting hole 201. The limiting hole 201 is connected to the rectangular groove 202. The rectangular groove 202 is used to connect the plate 204. When it is necessary to connect at least two pulp boards 101, the connecting plate 204 is rotated by the rotating column 203 so that the connecting plate 204 is located outside the rectangular groove 202 and perpendicular to the pulp board 101. At this time, the rubber plug 207 is located at the circular opening of the connecting plate 204. Then, the two connecting plates 204 are inserted into the rectangular groove 202 of each other so that the side walls of the two pulp boards 101 are in complete contact.

[0030] Then, the limiting plate 205 is deflected so that its T-shaped rod 206 aligns with the limiting hole 201 of the other side. Next, the T-shaped rod 206 is squeezed so that both the rubber plug 207 and the T-shaped rod 206 pass through the limiting hole 201 of the other side. At this time, the upper surface of the rubber plug 207 abuts against the bottom of the inner cavity of the rectangular groove 202, ensuring that the bottom end of the T-shaped rod 206 remains in the limiting hole 201. When both T-shaped rods 206 are inserted into the limiting hole 201 of the other side, the two pulp boards 101 are assembled and connected. The connecting plate 204 prevents the two pulp boards 101 from rotating up and down. The limiting plate 205 and the T-bar 206 prevent the two pulp boards 101 from separating or shifting, so that the combined pulp board 101 maintains good stability. The four sides of the pulp board 101 can be freely combined to meet the packaging needs of a large number of items. By forcefully lifting the T-bar 206, the rubber stopper 207 is pulled out from the limiting hole 201, thereby separating the combined pulp board 101.

[0031] In addition, a plurality of iron rings 208 corresponding to the positions of the limiting holes 201 are fixedly connected to the top of the pulp board 101, and the inner diameter of the iron rings 208 is the same as the inner diameter of the limiting holes 201.

[0032] A gap is left between the top of the connecting plate 204 and the pulp board 101 for the T-shaped rod 206 to slide up and down, so that the rubber plug 207 can pass through the iron ring 208 and the limiting hole 201. The iron ring 208 is used to improve the strength of the limiting hole 201, so that the limiting hole 201 can remain relatively intact during the repeated insertion and removal of the rubber plug 207, thereby ensuring the service life of the pulp board 101.

[0033] Specifically, stickers 209 are affixed to the four side walls of the pulp board 101, and each sticker 209 has a protrusion at the bottom. Limiting posts 210 are fixedly connected to the four side walls of the pulp board 101, and limiting grooves 211 that fit the limiting posts 210 are opened on the four side walls of the pulp board 101.

[0034] After the connecting plate 204 is rotated into the rectangular groove 202, the sticker 209 is pasted onto the rectangular groove 202 of the pulp board 101 to seal the opening of the rectangular groove 202 and prevent the connecting plate 204 from deflecting out of the rectangular groove 202 during transportation. When the connecting plate 204 is used, the sticker 209 is removed. The protrusion is used to completely remove the sticker 209 from the pulp board 101 to reduce residue. When the two pulp boards 101 are combined, the limiting posts 210 on the opposite sides of the two pulp boards 101 will insert into the limiting groove 211 of the other to improve the stability when the two pulp boards 101 are combined.

[0035] Furthermore, both the packaging cover 102 and the multiple support covers 103 are tapered, and the side walls of both the packaging cover 102 and the multiple support covers 103 are provided with multiple ventilation openings 104.

[0036] The conical design allows two pulp boards 101 to be stacked on top of each other, meaning that the packaging cover 102 and support cover 103 of one pulp board 101 can be inserted into the packaging cover 102 and support cover 103 of the other pulp board 101. The ventilation opening 104 allows air to circulate inside the packaging cover 102 and support cover 103. When the two pulp boards 101 are stacked, the ventilation opening 104 prevents the two pulp boards 101 from sticking together tightly due to negative pressure, thus ensuring that the stacked pulp boards 101 can be separated quickly.

[0037] Furthermore, the inner wall of the packaging cover 102 is fixedly connected with a plurality of anti-slip plates 105 arranged in a ring array, and the plurality of anti-slip plates 105 are staggered from the ventilation openings 104 of the packaging cover 102.

[0038] When an item is placed inside the packaging cover 102, the anti-slip sheet 105 increases the friction of the packaging cover 102 to prevent the item from deflecting inside the packaging cover 102.

[0039] During use, when connecting at least two pulp boards 101, the corresponding stickers 209 are peeled off from the pulp boards 101. Then, the rotating posts 203 on the two pulp boards 101 are rotated in sequence so that the connecting plate 204 is located outside the rectangular groove 202 and perpendicular to the pulp board 101. Next, the two connecting plates 204 are inserted into the rectangular groove 202 of the other, and the limiting posts 210 on the opposite side of the two pulp boards 101 are also inserted into the limiting groove 211 of the other, so that the side walls of the two pulp boards 101 are in complete contact. Then, the limiting plates 205 on the two pulp boards 101 are deflected so that the two T-shaped rods 206 are aligned with the limiting holes 201 of the other.

[0040] Next, the T-bar 206 is squeezed so that both the rubber plug 207 and the T-bar 206 pass through the iron ring 208 and the limiting hole 201 of the other. When both T-bars 206 are inserted into the limiting hole 201 of the other, the two pulp boards 101 are assembled and connected. By forcefully lifting the T-bar 206, the rubber plug 207 is pulled out from the limiting hole 201, and the assembled pulp boards 101 can be separated.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
