[0002] Paper models, also known as card models, are three-dimensional art creations carefully crafted with thick paper or cards as the medium. By accurately piecing together pre-cut paper parts, artists and enthusiasts can construct ever-changing three-dimensional forms, which not only beautify living spaces, but also become the preferred activity to inspire children's intelligence and promote parent-child interaction. In particular, three-dimensional paper models are widely praised in the fields of family and education due to their simplicity, safety, and entertaining characteristics.

[0003] The core challenge of building such models is to achieve a stable three-dimensional structure. A common approach is to use cross-docking between paper sheets, such as Figure 1 As shown, the vertical plug-in method is the most typical one, which aims to form a stable cross support system; in this process, the edges of the two paper sheets are cut into nested slots, aiming to achieve the purpose of combination through mutual insertion of the slots; however, the main disadvantage of this method is that the joint is easy to loosen, and the two parts may be easily separated, which requires the introduction of additional fixing elements to reinforce the intersection, which undoubtedly increases the complexity of production and may sacrifice the delicacy and ease of assembly of the work. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] like Figures 2 to 8 As shown, this embodiment shows a card paper mold cross-plugging structure, including a first paper sheet 1 and a sheet-shaped second paper sheet 2, the second paper sheet 2 has at least two layers of structure, namely a second layer structure 22 and a first layer structure 21 with a first plug hole 211, the first layer structure 21 and the second layer structure 22 are fixedly connected by a plug-in component 3, the first paper sheet 1 has a slot 11 extending from one end to the edge of the first paper sheet 1, at least one side of the open end of the slot 11 is fixed with a first ear 12 located in the slot 11, the first ear 12 is inserted into the first plug hole 211 of the first layer structure 21, and the second layer structure 22 acts on the first layer structure 21 to limit the first ear 12 from being separated from the first plug hole 211.

[0034] In this embodiment, the second paper sheet 2 includes a first layered structure 21 and a second layered structure 22. After the second paper sheet 2 is plugged into the second paper sheet 2, the first hanging ear 12 is inserted into the first insertion hole 211 of the first layered structure 21, and the second layered structure 22 is between the first hanging ear 12 and the inner wall of the slot 11. The second layered structure 22 acts on the first layered structure 21, thereby limiting the first hanging ear 12 from being separated from the first insertion hole 211. At this time, the first hanging ear 12 cooperates with the first insertion hole 211 to achieve a stable connection between the first layered structure 21 and the first paper sheet 1. The plug-in component 3 enables the first layered structure 21 and the second layered structure 22 to be fixedly connected, and finally the second paper sheet 2 is stably connected to the first paper sheet 1. In the embodiment, the first paper sheet 1 and the second paper sheet 2 are directly and firmly connected by their own structures, which can save the setting of additional fixing elements, simplify the plugging process of the first paper sheet 1 and the second paper sheet 2, and effectively maintain the original shapes of the first paper sheet 1 and the second paper sheet 2, which helps to improve the overall aesthetics of the paper model; in addition, the plugging and matching of the first hanging ear 12 and the first plug hole 211 can limit the first layered structure 21 from escaping from the slot 11 along the open end of the slot 11, and also limit the circumferential deflection of the first layered structure 21, so that the plugging of the first paper sheet 1 and the second paper sheet 2 is tighter, more stable and reliable, which helps to improve the overall stability of the paper model.

[0035] like Figures 2 to 3 As shown, in this embodiment, the first hanging ear 12 and the third hanging ear 13 are respectively fixed on both sides of the open end of the slot 11, and the first hanging ear 12 and the third hanging ear 13 are both located on the inner side of the slot 11. The second paper sheet 2 includes a first layered structure 21, a second layered structure 22 and a third layered structure 23, wherein the first layered structure 21 is provided with a first plug hole 211 for the first hanging ear 12 to extend into, and the third layered structure 23 is provided with a third plug hole for the third hanging ear 13 to extend into. When the first paper sheet 1 and the second paper sheet 2 are plugged in, the first hanging ear 12 is inserted into the first plug hole 211 to position the first layered structure 21, and the third hanging ear 13 is inserted into the third The third layer structure 23 is then positioned in the insertion hole, the second layer structure 22 is between the first layer structure 21 and the third layer structure 23, and the two sides of the second layer structure 22 act on the first layer structure 21 and the third layer structure 23 respectively, so as to limit the first hanging ear 12 from being separated from the first insertion hole 211 and the third hanging ear 13 from being separated from the third insertion hole. The connector 3 simultaneously penetrates the first layer structure 21, the second layer structure 22 and the third layer structure 23, so that the first layer structure 21, the second layer structure 22 and the third layer structure 23 form a second paper sheet 2 with a stable structure, thereby realizing the stable connection between the first paper sheet 1 and the second paper sheet 2.

[0036] In this embodiment, the plugging process of the first paper sheet 1 and the second paper sheet 2 is as follows:

[0037] First, the first layered structure 21 is inserted into the slot 11 until the first hanging ear 12 is aligned with the first insertion hole 211, and then the first layered structure 21 is gently pressed so that the first hanging ear 12 is inserted into the first insertion hole 211. Similarly, the third layered structure 23 is inserted into the slot 11 until the third hanging ear 13 is aligned with the third insertion hole, and then the third layered structure 23 is gently pressed so that the third hanging ear 13 is inserted into the third insertion hole. At this time, the first layered structure 21 and the third layered structure 23 form a preliminary positioning. Next, the second layered structure 22 is inserted between the first layered structure 21 and the third layered structure 23. The two sides of the second layered structure 22 act on the first layered structure 21 and the third layered structure 23 respectively to limit the first hanging ear 1 2 is separated from the first insertion hole 211 and the third hanging ear 13 is separated from the third insertion hole, thereby improving the connection stability between the first layer structure 21 and the third layer structure 23 and the first paper sheet 1. After the second layer structure 22 is inserted, the through holes 25 among the first layer structure 21, the second layer structure 22 and the third layer structure 23 are aligned with each other, and the plug-in component 3 passes through the three through holes 25 at the same time to realize the fixed connection between the first layer structure 21, the second layer structure 22 and the third layer structure 23, so as to form a second paper sheet 2 with a stable overall structure. At this time, the first paper sheet 1 is respectively plugged into the first insertion hole 211 and the third insertion hole on both sides of the second paper sheet 2 through the first hanging ear 12 and the third hanging ear 13, so as to realize the stable plugging of the first paper sheet 1 and the second paper sheet 2.

[0038] It should be noted that, in other embodiments, the slot 11 may also be provided with only the first ear 12, and the corresponding second paper sheet 2 only includes the first layered structure 21 and the second layered structure 22. After the first paper sheet 1 and the second paper sheet 2 are plugged in, the first ear 12 is inserted into the first insertion hole 211 of the first layered structure 21, and the second layered structure 22 is between the first ear 12 and the side wall of the slot 11. The two sides of the second layered structure 22 are respectively against the first layered structure 21 and the side wall of the slot 11. The second layered structure 22 acts on the first layered structure 21 to limit the first ear 12 from being separated from the first insertion hole 211, thereby realizing the plugging of the first paper sheet 1 and the second paper sheet 2.

[0039] In addition, those skilled in the art should know that after the first hanging ear 12 and / or the third hanging ear 13 are provided in the slot 11, space for inserting the second layered structure 22 should be reserved. Generally speaking, in the width direction of the slot 11, the protruding height of the first hanging ear 12 should be equal to or approximately less than the thickness of the first layered structure 21, and the protruding height of the third hanging ear 13 should be equal to or approximately less than the thickness of the third layered structure 23. The width of the slot 11 minus the protruding height of the first hanging ear 12 and / or the third hanging ear 13 is equal to or approximately greater than the thickness of the second layered structure 22. Based on this principle, those skilled in the art can adjust the thickness of the second layered structure 22, the first layered structure 21 and / or the third layered structure 23 according to the specific situation to optimize the stability of the overall structure.

[0040] like Figure 4 As shown, in this embodiment, the first hanging ear 12 and the third hanging ear 13 are integrally formed with the first paper sheet 1, and additional fixing elements can be omitted to fix the first hanging ear 12 and the third hanging ear 13, so that the overall structure of the first paper sheet 1 is more compact and simple, which helps to reduce the difficulty and cost of making the first paper sheet 1; at the same time, the first hanging ear 12 and the third hanging ear 13 are integrally formed with the first paper sheet 1, which can enhance the overall strength of the first hanging ear 12 and the third hanging ear 13, improve the positioning ability of the first plug hole 211 and the third plug hole, and make the plugging of the first paper sheet 1 and the second paper sheet 2 more firm and reliable. It should be noted that in this embodiment, the first hanging ear 12 and the third hanging ear 13 are symmetrically arranged along the center line of the slot 11, so that the force on the second paper sheet 2 is more balanced, and the plugging stability of the first paper sheet 1 and the second paper sheet 2 can be improved; of course, it can be understood that in other embodiments, the first hanging ear 12 and the third hanging ear 13 can also be asymmetrically arranged; in addition, the position of the first hanging ear 12 and the third hanging ear 13 in the slot 11 can also be on the side wall near the bottom.

[0041] In this embodiment, the first hanging ear 12 passes through the first insertion hole 211 of the first layered structure 21 and abuts against the second layered structure 22. The third hanging ear 13 passes through the third insertion hole of the third layered structure 23 and abuts against the second layered structure 22. The first hanging ear 12 and the third hanging ear 13 respectively abut against the two sides of the second layered structure 22, so that the second layered structure 22 can be stably positioned between the first hanging ear 12 and the third hanging ear 13 of the slot 11, reducing the shaking amplitude of the second layered structure 22, making the positioning of the second layered structure 22 more reliable, and facilitating the plug-in component 3 to connect the first layered structure 21, the second layered structure 22 and the third layered structure 23, which helps to reduce the difficulty of plugging the first layered structure 21, the second layered structure 22 and the third layered structure 23.

[0042] In order to achieve rapid positioning of the second paper sheet 2 and the first paper sheet 1, in this embodiment, the ends of the first layered structure 21, the second layered structure 22 and the third layered structure 23 extending into the slot 11 are all provided with positioning grooves 24, and the positioning grooves 24 are formed inwardly from the edge of the second paper sheet 2. When the second paper sheet 2 is plugged into the first paper sheet 1, the bottom end of the slot 11 extends into the positioning groove 24, and the positioning groove 24 cooperates with the bottom end of the slot 11, so that the user can clearly perceive that the third layered structure 23 has been installed in place, making the alignment of the third hanging ear 13 and the third plug hole simpler and faster, and also can achieve rapid alignment of the third layered structure 23 with the first layered structure 21 and the second layered structure 22, which helps to speed up the plugging speed of the first paper sheet 1 and the second paper sheet 2.

[0043] like Figure 7 and Figure 8 As shown, the connector 3 in this embodiment includes a main body 31, a plug connector 32 and a connecting portion 33 for connecting the plug connector 32 and the main body 31. The first layer structure 21 and the second layer structure 22 are both provided with a through hole 25 for the plug connector 32 to pass through. The plug connector 32 includes a connecting end 321 connected to the connecting portion 33 and a plug end 322 away from the connecting portion 3333. A guide surface 323 is provided between the plug end 322 and the connecting end 321. The width of the connecting end 321 is greater than the width of the through hole 25. A limiting groove 34 matching the inner wall of the through hole 25 is formed between the connecting end 321, the connecting portion 33 and the main body 31. The connector 3 is plugged into and matched with the through hole 25 so that the second layer structure 22 and the third layer structure 23 are simultaneously positioned in the limiting groove 34.

[0044] In addition, the connecting portion 33 of the present embodiment is in the shape of an elongated strip, and the length of the connecting portion 33 is greater than the length of the through hole 25. The connecting portion 33 provides sufficient length support for the plug connector 32 to pass through the through hole 25, so that the plug connector 32 and the main body 31 are respectively located on both sides of the second paper sheet 2; in addition, the two ends of the connecting portion 33 are respectively perpendicular to the connecting end 321 and the main body 31, the overall width of the connecting end 321 is greater than the width of the connecting portion 33, and the connecting end 321 extends to both sides of the connecting portion 33, so that a limiting groove 34 is formed between the connecting end 321, the connecting portion 33 and the main body 31, wherein the connecting end 321 and the main body 31 are partially shaped The side walls of the limiting groove 34 are formed by the connecting portion 33, and the bottom wall of the limiting groove 34 is formed by the connecting portion 33, and the side walls are kept perpendicular to the bottom wall, so that the limiting groove 34 is an overall U-shaped structure, which is more matched with the structure at the inner wall of the through hole 25. After the connector 3 is plugged into the through hole 25, the limiting groove 34 and the second paper piece 2 have a larger contact area, thereby improving the positioning ability of the limiting groove 34 on the second paper piece 2, reducing the shaking amplitude of the second paper piece 2, and improving the plug-in stability of the connector 3 and the second paper piece 2. At the same time, it can also disperse the stress on the head of the connector 3, reduce the possibility of deformation of the connector 32, and significantly extend the service life of the connector 32.

[0045] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes but is not limited to the contents described in the drawings and the above specific implementation.
