[0029] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.
[0030] Example 1
[0031] Please see Figure 1 , 2 As shown in Figure 4, this embodiment provides a multi-form changeable 3D party card, including:
[0032] The main card 1 and the sub-card 2 are connected to the sub-card 2 by folding on one side, so that the two can form a three-dimensional structure together. On the inner side of the main card 1 and the sub-card 2, four foldable support corners 3 are fixedly set in a trapezoidal shape. The top of these four support corners 3 is fixedly set with the same foldable house-shaped origami 4. The top of the house-shaped origami 4 is symmetrically folded with two windows 6. At the same time, on the top of the house-shaped origami 4, below the windows 6, there are also two doors symmetrically folded.
[0033] To enable flexible opening and closing of window 6 and door 5, a pull-out mechanism is provided. This mechanism includes through slots respectively opened at the top and bottom of the main card 1 and the sub-card 2. A first pull rod 7 is inserted into the top through slot of both the main card 1 and the sub-card 2, while a second pull rod 8 is inserted into the bottom through slot. One end of the first pull rod 7 is fixedly connected to the back side of window 6, and one end of the second pull rod 8 is fixedly connected to the back side of door 5. In this way, the user can open window 6 and door 5 respectively by pulling the first pull rod 7 and the second pull rod 8.
[0034] The other ends of the two No. 1 pull bars 7 and the two No. 2 pull bars 8 are all provided with folded edges for easy pulling. These folded edges not only increase the ease of use of the pull mechanism, but also make it more convenient and comfortable for users to pull the bars.
[0035] Example 2
[0036] Improvements based on Example 1: See Appendix Figure 2 and 3 In order to maintain the stability of the main card 1 and the sub-card 2 in the closed state, a strap 12 is fixedly installed on one side of the main card 1. A first magnet 13 is fixedly installed on the inside of the strap 12, while a second magnet 14 is embedded on one side of the sub-card 2. When the main card 1 and the sub-card 2 are closed, the first magnet 13 and the second magnet 14 will attract each other, thereby ensuring a tight fit between the two.
[0037] To enhance the party atmosphere and interactivity, an electronic chip 9 is attached to the inside of the main card 1, and a trigger piece 11 is attached to the inside of the sub-card 2. One end of the trigger piece 11 is fixedly connected to the switch of the electronic chip 9. When the main card 1 and the sub-card 2 are unfolded, the trigger piece 11 will activate the switch of the electronic chip 9, energizing it. At this time, two LED lights 10 electrically connected to the electronic chip 9 (model: S7zANxFD) will be lit, adding more brilliance and fun to the party. These two LED lights 10 are respectively attached to the inside of the main card 1 and the sub-card 2, located at the bottom of the house-shaped origami 4.
[0038] Example 3
[0039] Improvements based on Embodiments 1 and 2: See Appendix Figure 1 To make it easier for users to add personalized decorations and greetings to party cards, a pattern adhesive area 101 is set on the outside of the main card 1. Users can paste or draw patterns or decorations that match the party theme in this area to make the card more beautiful and unique. In addition, a message area 102 is set below the pattern adhesive area 101 for users to write down their blessings or related information for the party.
[0040] The usage process and working principle of this utility model technical solution are as follows:
[0041] When you start using it, first take the party card out of the packaging and observe it to make sure that the main card 1 and the sub-card 2 and all the folds on them are intact. Then write a message or party information in the message area 102 on the outside of the main card 1 to add a personalized element. Then paste or draw a pattern or decoration that matches the party theme in the pattern adhesive area 101 to make the card more beautiful.
[0042] Then, move the strap 12 to disengage magnet 13 from magnet 14. Then, open the main card 1 and the sub-card 2 and unfold them along the connection. After the main card 1 and the sub-card 2 are unfolded, pull the inner support folds 3 to lift them up. When the four support folds 3 are lifted up, the house-shaped origami 4 at the top is lifted up. When the main card 1 and the sub-card 2 are folded to 180 degrees, the house-shaped origami 4 is fully lifted up to form a complete house.
[0043] During the unfolding of the main card 1 and the sub-card 2, the sub-card 2 will pull the trigger piece 11. As the trigger piece 11 is pulled, it will cause the switch on the electronic chip 9 to slide, so that the electronic chip 9 is powered on, thereby lighting up the two LED lights 10 and adding atmosphere to the overall card.
[0044] When you need to open the window 6 of the origami house 4, first pinch the folded edge of the first pull bar 7 and pull it gently. As the first pull bar 7 is pulled, it causes the window 6, which is fixedly connected to one end, to rotate inward in a fan shape on the origami house 4, so that the window 6 opens. The window 6 on the other side also opens according to the same principle, thereby increasing the interactivity and fun of the party.
[0045] When you need to open the door 5 of the origami house 4, first pinch the folded edge of the second pull bar 8 and pull it gently. As the second pull bar 8 is pulled, it causes the door 5, which is fixedly connected to one end, to rotate inward in a fan shape on the origami house 4, so that the door 5 opens. The other door 5 also opens according to the same principle, thereby increasing the interactivity and fun of the party.
[0046] When you need to store them, fold the cards back to their original state in reverse order for easy viewing next time. Store the cards in a dry, cool place, away from direct sunlight and moisture, to keep them intact and beautiful.
