Detailed Description of the Preferred Embodiments

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0029] As Figure 1-7As shown in the figure, the present utility model provides an embedded packaging structure, including an upper plate 1 and a lower plate 2 corresponding up and down. A buffer pad 3 is provided between the upper plate 1 and the lower plate 2. The bottom of the upper plate 1 is adhesively bonded to the top of the buffer pad 3, and the bottom of the buffer pad 3 is adhesively bonded to the top of the lower plate 2, so that the upper plate 1, the buffer pad 3 and the lower plate 2 form a retractable integrated structure;

[0030] At least one first through hole 11 with corresponding positions is provided in both the upper plate 1 and the buffer pad 3, so that consumers can directly contact the upper surface of the lower plate 2 by passing through the first through hole 11 from above the upper plate 1. Among them, the upper plate 1, the lower plate 2, the buffer pad 3 and the first through hole 11 jointly form a placement position 12 for fixing a product (not shown). That is to say, at this time, the lower plate 2 forms the bottom of the placement position 12, and the upper plate 1 and the buffer pad 3 constitute the side walls of the placement position 12;

[0031] Specifically, in order to solve the problem of folding and storing the packaging pad in the prior art, the buffer pad 3 is a honeycomb structure that can be stretched up and down. When in use, the upper plate 1 and the lower plate 2 are separated up and down to stretch the buffer pad 3 up and down, thereby increasing the vertical height of the side walls of the placement position 12; when folding and storing, only the distance between the upper plate 1 and the lower plate 2 needs to be compressed up and down to contract the buffer pad 3 up and down, thereby reducing the overall vertical height of the packaging structure and facilitating the storage and transportation of the packaging structure;

[0032] Furthermore, in order to fix the stretched state of the buffer pad 3, several first support plates 13 are rotatably connected to the edge of the upper plate 1 at the first through hole 11. The number of the first support plates 13 corresponds to the number of sides of the first through hole 11. That is to say, when the first through hole 11 is quadrilateral, four first support plates 13 corresponding to the four sides of the first through hole 11 are provided on the upper plate 1; the first support plates 13 are rotated and bent towards the lower plate 2, so that one end of the first support plate 13 is connected to the upper plate 1, the other end is connected to the lower plate 2, and its side wall abuts against the side wall of the first through hole 11 in the buffer pad 3, so that the first support plate 13 is located between the buffer pad 3 and the product. The support structure of the first support plate 13 is simple and convenient to install and disassemble, facilitating the quick packaging or folding and transportation by consumers;

[0033] It should be noted that since the buffer pad 3 is formed by adhesively bonding several paper strips up and down, in the stretched state, the buffer pad 3 has a tendency to contract under the action of its elastic force. Through the up and down supporting action of the first support plate 13, the buffer pad 3 is kept in the stretched state. At the same time, the buffer pad 3 and the first support plate 13 can provide support and buffering effects for the fixation of the product;

[0034] Preferably, as Figure 4 shown, Figure 4 it is Figure 1 a sectional view along the middle sectional line L1. The vertical extension direction of the first support plate 13 is perpendicular or nearly perpendicular to the upper plate 1 or the lower plate 2. Through this vertical setting, better supporting force can be obtained between the upper plate 1 and the lower plate 2, making it not easy to fold, and facilitating the embedding and fixing of the product at the placement position 12;

[0035] Preferably, as Figure 5 shown, since the side walls of some products are not vertical structures, the vertical extension direction of the first support plate 13 forms an inclination angle A with the upper plate 1 or the lower plate 2, and the inclination angle A corresponds to the inclination angle of the side wall of the product, so as to achieve a better embedded packaging effect;

[0036] Specifically, the end of the first support plate 13 is provided with a first lug 131, and the lower plate 2 in the placement position 12 is provided with a first slot 132 corresponding to the first lug 131 at the end of the first support plate 13. Through the setting of the first lug 131 and the first slot 132, it is convenient to fix the inclination angle A of the first support plate 13 and improve the supporting effect of the packaging structure;

[0037] Specifically, in daily packaging, some products have a convex part (not shown), which makes the bottom of the planar placement position 12 unable to fix the product, and the entire product cannot be accommodated in the placement position 12 either. Therefore, the first support plate 13 can be provided with a step 14 matching the outer wall structure of the product. Through the stepped support structure of the step 14, the placement position 12 can be more closely attached to the outer wall of the product;

[0038] Meanwhile, as Figure 4-6 shown, where Figure 6 it is Figure 1 a sectional view along the middle sectional line L2. A bottom plate 4 corresponding to the lower plate 2 is further provided below the lower plate 2. A connecting plate 5 is provided between the edge of the bottom plate 4 and the edge of the lower plate 2. One end of the connecting plate 5 is connected to the edge of the bottom plate 4, and the other end is connected to the edge of the lower plate 2, so as to form a cavity 41 between the lower plate 2 and the bottom plate 4; during packaging, the convex part on the product can extend through the lower plate 2 into the cavity 41. Although the convex part extends into the cavity 41, most of the structure of the product is located within the placement position 12 and is fixed, so that the placement position 12 can still stably fix the product and provide a good buffering effect for it;

[0039] Further, a second through hole 15 is provided in the lower plate 2 at the bottom of the placement position 12, and the convex part of the product can extend into the cavity 41 through the second through hole 15;

[0040] Preferably, a second support plate 16 is rotatably connected to the edge of the second through hole 15. The second support plate 16 is rotationally bent towards the bottom plate 4, so that one end of the second support plate 16 is connected to the lower plate 2 and the other end is connected to the bottom plate 4, thereby providing a fixing effect on the vertical distance of the cavity 41;

[0041] More preferably, a second lug 161 is provided at the end of the second support plate 16, and the bottom plate 4 is provided with a second card slot 162 corresponding to the position of the second lug 161. Through the arrangement of the second lug 161 and the second card slot 162, the second support plate 16 can be better fixed, and the support stability of the second support plate 16 is improved;

[0042] Furthermore, a third through hole 42 communicating with the cavity 41 is provided in the bottom plate 4. A third support plate 43 is rotatably connected to the edge of the third through hole 42. The third support plate 43 is rotationally bent towards the lower plate 2, so that one end of the third support plate 43 is connected to the lower plate 2 and the other end is connected to the bottom plate 4, thereby further strengthening the vertical distance of the cavity 41;

[0043] Wherein, a third lug 431 is provided at the end of the third support plate 43, and a third card slot 432 corresponding to the position of the third lug 431 is provided in the lower plate 2, thereby improving the support stability of the third support plate 43;

[0044] Specifically, a plurality of sealing plates 6 are rotatably connected to the edge of the upper plate 1. The number of the sealing plates 6 corresponds to the number of sides of the upper plate 1. That is to say, when the upper plate 1 is quadrilateral, each side of the upper plate 1 is rotatably connected with the sealing plate 6;

[0045] During use, the sealing plate 6 is rotationally bent towards the bottom plate 4, so that the sealing plate 6 shields and closes the buffer pad 3, the lower plate 2, the connecting plate 5 and the bottom plate 4, and the side wall of the sealing plate 6 abuts against the side wall of the connecting plate 5, so that the sealing plate 6 can wrap the upper plate 1, the lower plate 2, the buffer pad 3 and the bottom plate 4, thereby making the embedded packaging structure more integrated and beautiful, and at the same time further strengthening the packaging structure;

[0046] Further, a locking plate 61 is provided at the connection between adjacent sealing plates 6. The locking plate 61 is fixedly connected to adjacent two sealing plates 6 respectively, so that the sealing plate 6 can keep abutting against the connecting plate 5, and at the same time further improve the support stability of the connecting plate 5 and the buffer pad 3;

[0047] Among them, the fixed connection can be an adhesive connection, a snap connection, or a connection using adhesive tape;

[0048] Specifically, the buffer pad 3 is preferably kraft paper, and the upper plate 1, the lower plate 2, the bottom plate 4, the first support plate 13, the second support plate 16, and the third support plate 43 are preferably corrugated cardboard.

[0049] The following is a detailed description of the working principle of the present utility model;

[0050] During use, first unfold the upper plate 1 and the lower plate 2 up and down so that the buffer pad 3 can be stretched, and then bend the first support plate 13 and fix the stretching of the buffer pad 3 through the snap-fit of the first lug 131 and the first card slot 132;

[0051] Next, fix the bottom plate 4 below the lower plate 2 through the connecting plate 5 to form the cavity 41 therebetween, and then further reinforce the cavity 41 up and down by bending the second support plate 16 and the third support plate 43. Subsequently, bend the sealing plate 6 at the edge of the upper plate 1 and abut it against the connecting plate 5 to make the packaging structure more integrated and have better support ability;

[0052] Finally, place the product in the placement position 12 so that the first support plate 13 and the buffer pad 3 provide good fixing and buffering effects for the side wall of the product. At the same time, for some products such as plugs, the plug-in part of the plug can be inserted into the second through hole 15, so as to facilitate the more fitting fixation of the entire plug by the placement position 12.

[0053] The innovation of the present utility model lies in that by providing a vertically telescopic buffer pad between the upper plate and the lower plate and the integrated design of the three, a placement position that matches the product and has a good buffering effect can be presented by separating the upper plate and the lower plate, which is simple and convenient, and consumers do not need to prepare additional buffer materials; at the same time, by reducing the distance between the upper plate and the lower plate, the buffer pad can be compressed, making the overall packaging structure smaller in volume and convenient for storage or transportation.

This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
