Abstract
Description
Technical Field
[0001] This utility model relates to the field of 3D greeting card technology, and in particular to a double Velcro positioning pop-up 3D greeting card structure. Background Technology
[0002] Pop-up pop-up greeting cards currently on the market have a relatively simple structure. The existing pop-up pop-up greeting card technology has an internal structure of X-shape, and the forming method is that the bottom paper sheet lifts up, the greeting card pops up, and the base stands on the table for display.
[0003] The shortcomings and problems of existing technologies:
[0004] The existing technical structure has an internal support uniformly X-shaped after being unfolded. The product display angle is limited by this shape, which has certain design limitations. There are many assembly parts, and the bonding positions require high precision. The error tolerance is small, and misalignment may cause the function to be unrealizable. This structure is quite sensitive to the height of the product. If it exceeds a certain height, it will cause the center of gravity to be unstable.
[0005] The preceding description is intended to provide general background information and does not necessarily constitute prior art. Utility Model Content
[0006] The purpose of this utility model is to provide a double Velcro positioning pop-up three-dimensional greeting card structure, which solves the problem of fixed structural shape, has a rich variety of design styles and designs, and is extremely widely used.
[0007] This utility model provides a double Velcro positioning pop-up three-dimensional greeting card structure, including a front piece, a back piece, and an outer perimeter. Both the front and back pieces have serrated cross-sections and multiple slots spaced apart on each. The slots on the front and back pieces are sequentially inserted to form multiple small and large rhombuses, which are adjacent to each other. A first front adhesive position and a second front adhesive position are integrally formed at both ends of the front piece, and a first and a second back adhesive position are integrally formed at both ends of the back piece. The first front adhesive position and the first back adhesive position are bonded together, and the second front adhesive position and the second back adhesive position are bonded together. The outer perimeter is fitted onto the front and back pieces, with one end of the outer perimeter bonded to the first front adhesive position and the first back adhesive position, and the other end of the outer perimeter bonded to the second front adhesive position and the second back adhesive position.
[0008] Using the above technical solution, starting from the adhesive positions of the first front piece and the first rear piece, the structure is opened and stood upright on both sides. Through the mutual adhesion between the two pairs of hook and loop fasteners, the structure is automatically formed and fixed, achieving the purpose of use and display. During the forming process, the hook and loop fasteners balance the structure's own elasticity through mutual adhesive force, solving the problem of fixing the structure's shape. Furthermore, using the outer center fold line as a reference line, the structure can be flattened towards the center to 0 degrees for transportation or storage. This utility model structure can be repeatedly opened and flattened for use as needed.
[0009] Furthermore, the double Velcro positioning pop-up three-dimensional greeting card structure also includes Velcro, with Velcro connected to the middle of both the front and rear pieces; the Velcro on the front and rear pieces is connected to a side close to the inner wall of the periphery, and two other Velcros that cooperate with the Velcro on the front and rear pieces are connected to the inner wall of the periphery.
[0010] Furthermore, a central broken line is provided in the middle of both the front and rear parts of the periphery.
[0011] This utility model discloses a double-hook and loop fastener positioning pop-up three-dimensional greeting card structure. Starting from the adhesive positions of the first front and rear pieces, it unfolds to both sides and stands upright. Through the mutual adhesion between the two pairs of hook and loop fasteners, the structure is automatically formed and fixed, achieving its purpose of use and display. During the forming process, the hook and loop fasteners balance the structure's own elasticity through mutual adhesion, solving the problem of shape fixation. Furthermore, by using the outer center fold line as a reference line, it can be flattened towards the center of the structure to 0 degrees for transportation or storage. This utility model structure can be repeatedly unfolded and flattened for use as needed. Based on this structure, there is a rich variety of design styles and designs, and its application scenarios are extremely wide. This utility model discloses a double-hook and loop fastener positioning pop-up three-dimensional greeting card structure. Unlike existing upward pop-up designs, this invention uses serrated front and back pieces that interlock one-to-one through slots to form a spring-loaded left-right push-pull structure with multiple small and large rhombus-shaped grids. The innovative design incorporates two pairs of Velcro fasteners for precise positioning, allowing the user to easily unfold and stand upright without conscious thought. The internal double-serrated design, with interlocking slots, can split into multiple smaller pieces, creating a more layered and angular display. The two pairs of Velcro fasteners for positioning are cost-effective, easy to assemble, and cleverly balance the structure's elasticity while solving the positioning problem. The precisely calculated fold angle allows it to be flattened to 0 degrees, and when standing, it fully supports itself within the outer frame. This invention offers relatively high flexibility in terms of design size, style, and design. Attached Figure Description

[0034] Further reference Figure 1 , Figure 2The double Velcro positioning pop-up three-dimensional greeting card structure of this utility model also includes Velcro 900, which is connected to the middle of the front piece 100 and the rear piece 200; the Velcro 900 on the front piece 100 and the rear piece 200 are all connected to one side near the inner wall of the outer perimeter 300, and two other Velcro 900 that cooperate with the Velcro 900 on the front piece 100 and the rear piece 200 are connected to the inner wall of the outer perimeter 300.
[0035] Further reference Figure 1 , Figure 2 The present invention provides a central fold line 310 in the middle of the front and the middle of the rear of the outer periphery 300.
[0036] like Figure 1 As shown, it should be noted that the double Velcro positioning pop-up three-dimensional greeting card structure of this utility model starts from the first front adhesive position 110 and the first rear adhesive position 210, and stands up on both sides.
