Description

Technical Field

[0001] This utility model belongs to the field of packaging structure technology, specifically relating to a cushioning and bottom-supporting packaging structure. Background Technology

[0002] Many products require packaging structures after production to protect and cushion them during transport. Common packaging structures include pulp product outer packaging and plastic product outer packaging. Pulp product outer packaging is molded from pulp and has grooves that match the shape and size of the product. The product is then inserted into these grooves, and the product and pulp product outer packaging are placed together in an outer box.

[0003] Many existing products have varying structural shapes, resulting in different groove widths. Therefore, some designs incorporate linings within the grooves of the pulp product packaging, using different linings to accommodate different product shapes and sizes. This approach allows pulp product packaging produced with a single mold to be used for packaging multiple products.

[0004] In the above solution, the outer packaging and inner lining of pulp products are manufactured separately, and then the two are connected and combined by means of bonding to form a complete product containment packaging. However, the stability of the bonding method is poor, and they are prone to separation due to pulling or other means (the surface of many pulp product outer packaging is prone to separation when pulled, resulting in the failure of the bonding between the pulp product outer packaging and the inner lining), or the connection strength is affected by external factors such as rising temperature. Utility Model Content

[0005] The present invention aims to provide a cushioning and bottom-supporting packaging structure to solve the problem of poor connection stability of various parts of the existing packaging structure mentioned above.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cushioning and bottom-supporting packaging structure, comprising... The bottom plate has symmetrical limit blocks on both sides of the top, and the limit blocks have a first limit groove and a second limit groove on their opposite side walls. The packaging plate has two pieces, each corresponding to a limit block. The packaging plate has a protective part and a connecting part. The protective part is located inside the two limit blocks and abuts against the limit blocks. A connecting plate is fixed to the side wall of the protective part. The connecting plate is adapted to the first limit groove. The connecting part is fixed to the end of the protective part and abuts against the side wall of the limit block and is inserted into the second limit groove. The limit rod has two rods, and the limit block, connecting plate and connecting part on the same side are connected by the same limit rod.

[0007] The principle and effects of this technical solution: 1. By separating the packaging board from the base plate and the limiting block into two parts, the base plate and the limiting block are made into a whole, and the packaging board is made into a whole. Thus, each part can be manufactured and formed separately, thereby reducing the manufacturing difficulty. Through the adaptation of the connecting plate with the first limiting groove and the adaptation of the connecting part with the second limiting groove, the limiting block can play a certain locking and limiting effect on the packaging board. Furthermore, through the insertion of the limiting rod into the limiting block and the packaging board, the packaging board cannot be separated from the limiting block, ensuring the connection stability between the packaging board and the limiting block. At the same time, the protective part can provide cushioning protection for the product.

[0008] 2. The connecting plate is inserted into the first limiting plate to restrict the left and right movement of the protective part. The connecting part restricts the forward and backward movement of the protective side by abutting against the limiting block and inserting around to the second limiting groove, thereby achieving horizontal limiting. The insertion of the limiting rod with the limiting block, the connecting plate and the connecting part restricts the vertical movement of the connecting plate and the connecting part relative to the limiting block. At the same time, it restricts the connecting plate and the connecting part from disengaging from the first limiting groove and the second limiting groove, respectively, ensuring the stability of the connection of the structure.

[0009] The present invention is further configured such that: the side wall of the limiting block has a clearance notch, the clearance notch is adjacent to the second limiting groove, and the connecting part abuts against the clearance notch.

[0010] The principle and effect of this technical solution: By setting the clearance notch, the thickness of the connecting part can be accommodated, so that the connecting part will not further occupy external space on the back of the limiting block, thereby improving the overall consistency and aesthetics of the structure.

[0011] The present invention is further configured such that: the protective part has a first protective edge, a second protective edge and a transition edge, the first protective edge and the second protective edge are arranged alternately and connected by the transition edge, the second protective edge abuts against the limiting block, the connecting plate is fixed to the side wall of the second protective edge, and there is a gap between the first protective edge and the limiting block.

[0012] The principle and effect of this technical solution: By setting the first and second protective edges, the overall protective part is similar to the zigzag structure of a corrugated board. Through the zigzag setting, it has a certain degree of extensibility and strength, thus providing support for the product that is snapped into the inner side of the two protective parts and providing cushioning through deformation.

[0013] The present invention is further configured such that: the base plate has a plurality of spaced support platforms, the positions of which correspond to the positions of the second protective edges, and the support platforms are located between the second protective edges on both sides.

[0014] The principle and effect of this technical solution: The support platform can act as a reinforcing rib, making the base plate stronger. At the same time, the support platform can support the product and lift it away from the base plate, creating a certain gap between the product and the base plate. This gap facilitates the user to detach the product from the packaging structure.

[0015] The present invention is further configured such that the base plate, the limiting block and the support platform are all hollowed-out structures at the bottom.

[0016] The principle and effect of this technical solution: The hollow design can reduce the cost of the product and enable one-piece molding.

[0017] The present invention is further configured such that the limiting block has multiple recesses arranged alternately.

[0018] The principle and effect of this technical solution: By making the surface structure of the limiting block more complex through multiple recesses, the strength of the limiting block can be enhanced.

[0019] The present invention is further configured such that the height of the limiting block is between one-third and two-thirds of the height of the protective part.

[0020] The principle and effect of this technical solution: By limiting the height of the limiting block relative to the protective part, the limiting block can play a stabilizing side support role, while also saving costs to a certain extent. Attached Figure Description

Base plate; 120. Limiting block; 121. First limiting groove; 122. Second limiting groove; 123. Clearance notch; 124. Recessed part; 130. Support platform; 210. Protective part; 211. First protective edge; 212. Second protective edge; 213. Transition edge; 220. Connecting part; 230. Connecting plate; 310. Limit rod.

[0023] Example 1: As attached Figure 1-5 As shown, this utility model discloses a cushioning and bottom-supporting packaging structure, including a base plate 110, a limiting block 120, and a packaging plate. The limiting blocks 120 are symmetrically arranged on the front and rear sides of the top of the base plate 110. The limiting blocks 120 are respectively provided with a first limiting groove 121 and a second limiting groove 122 on the opposite side walls of the limiting blocks 120. The first limiting groove 121 is located on the opposite side of the limiting blocks 120, and the second limiting groove 122 is opened on the opposite side of the limiting blocks 120. The two ends of the opposite side of the limiting blocks 120 are provided with clearance notches 123 adjacent to the second limiting groove 122. The limiting blocks 120 have a plurality of alternating recesses 124.

[0024] The packaging plate has two pieces, each corresponding to one of the two limiting blocks 120. Each packaging plate has a protective portion 210 and a connecting portion 220. The protective portion 210 is located inside the two limiting blocks 120 and has a first protective edge 211, a second protective edge 212, and a transition edge 213. The first protective edge 211 and the second protective edge 212 are arranged alternately and connected by the transition edge 213. The second protective edge 212 abuts against the limiting block 120. The connecting plate 230 is fixed to the side wall of the second protective edge 212. The first protective edge 211 and the limiting block 120... There is a gap between the 0 and the connecting plate 230 is adapted to the first limiting groove 121. The connecting part 220 is fixed to the end of the protective part 210 (if the first protective edge 211 is located at the end, the first protective edge 211 is connected to the connecting part 220; if the second protective edge 212 is located at the end, the second protective edge 212 is connected to the connecting part 220). The connecting part 220 abuts against the side wall of the limiting block 120 and is inserted into the second limiting groove 122. The connecting part 220 abuts against the clearance notch 123. After the connecting part 220 and the clearance notch 123 are adapted, the back of the limiting block 120 is a plane.

[0025] Two limit rods 310 are provided. The limit block 120, connecting plate 230 and connecting part 220 on the same side are connected by the same limit rod 310.

[0026] The base plate 110 has multiple spaced support platforms 130, the positions of which correspond to the positions of the second protective edges 212, and the support platforms 130 are located between the second protective edges 212 on both sides. The base plate 110, the limiting block 120 and the support platforms 130 are integrally formed and all have a hollow bottom structure. The height of the limiting block 120 is between one-third and two-thirds of the height of the protective part 210.

[0027] The base plate 110, the limiting block 120, and the support platform 130 can be integrally injection molded for plastic products. The packaging plate is a plastic product (manufactured and processed by injection mold). This method simplifies the mold structure by molding the packaging plate and the base plate 110 separately. At the same time, the size of the packaging plate can be adjusted relative to the base plate 110 by replacing the packaging plate. The production speed is fast and there are fewer post-processing steps. Specifically, it can be used to fit the two packaging plates of this structure on the side of computers, monitors, etc., so as to achieve the effect of edge protection and bottom support. Or, for some smaller parts, it can be placed on the inside of the two packaging plates for snap-fit ​​and limiting. This is only an example and is not a limitation on the application scenarios of this packaging structure. Furthermore, by changing the model of the packaging plate, packaging plates of different shapes and sizes can be replaced, thus making the packaging structure highly reusable and detachable.

[0028] Example 2, as Figure 6 As shown, the difference from Embodiment 1 is that the packaging board is a pulp molding product (specifically, corrugated cardboard), which is cheaper to purchase directly. The corrugated cardboard is then processed by pleating the edges and opening the center, and the opening is bent into a connecting plate 230. This method is low-cost, does not require multiple sets of molds, and is suitable for small-batch production. Furthermore, the height of the connecting plate 230 is lower than the height of the limiting block 120 to ensure that the packaging board and the limiting block 120 abut against each other.

[0029] The parts of the device not covered herein are the same as or can be implemented using existing technologies.

[0030] Among them, insert and sliding insert are mating bodies with holes, the cross section of the shaft or rod matches the hole, and the shaft or rod can slide relative to the hole. Threaded insert is a hole with threads, the shaft or rod is threaded, and the shaft or rod is connected to the mating body by screwing. Detachable installation can be by bolt thread connection or bolt and nut connection, etc., depending on what can be actually achieved.
