Description

Technical Field

[0001] This utility model relates to the field of splicing board mold technology based on Velcro connection, specifically a splicing board mold assembly based on Velcro connection. Background Technology

[0002] As is well known, in the field of children's toys, building toys are a type of educational toy that uses building blocks and molds to create structures. The building block mold is the core component used to position the building blocks and connect them. Its structural design directly affects the ease of assembly and the stability of the assembled structure.

[0003] In existing technologies, the design of assembly toy molds mostly focuses on conventional shapes such as straight lines and arcs, with insufficient development of targeted triangular assembly molds. Related technologies often rely on traditional plug-in or snap-fit ​​structures for connecting triangular assembly plates. Plug-in molds require protrusions on the edges of the assembly plates and corresponding grooves in the mold, with the protrusions inserting into the grooves to achieve connection. Snap-fit ​​molds require the design of elastic snaps and slots, with the snaps engaging the slots for fixation. However, this leads to poor adaptability and inaccurate positioning, resulting in inconsistencies in the angles and side length ratios of equilateral and isosceles triangular assembly plates. The example is unique in that the existing mold's groove size has low matching accuracy with the triangular splicing plate, and there is no dedicated positioning structure designed for the triangular shape. This causes the splicing plate to easily shift and wobble after being embedded in the mold, increasing the difficulty of subsequent splicing. On the other hand, the complex operation affects the user experience. The plug-in and snap-fit ​​connections require extremely high splicing alignment accuracy. Children need to repeatedly adjust the angle and position of the splicing plate to complete the connection when building, which is difficult to operate. In addition, the snap-fit ​​structure requires a large amount of pressing force, which is difficult for young children to operate independently. They are likely to lose interest in the game due to repeated failures. Summary of the Invention

[0004] To overcome the problems of poor adaptability leading to inaccurate positioning and complex operation affecting the user experience of existing splicing panel mold components based on Velcro connections, this utility model provides a splicing panel mold component based on Velcro connections that has good adaptability, accurate positioning, and simple operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a splicing panel mold assembly based on Velcro connection, comprising: An equilateral triangle splicing mold, wherein the mold has an equilateral triangle fitting groove that adapts to the shape of the equilateral triangle splicing plate, and the splicing surface of the mold has an equilateral triangle hook and loop fastener mounting cavity. The cavity wall of the mounting cavity has equilateral triangle positioning posts arranged in an equilateral triangle pattern for inserting into the positioning holes of the equilateral triangle hook and loop fasteners to achieve positioning. An isosceles triangle splicing mold is provided, wherein the isosceles triangle splicing mold is provided with an isosceles triangle fitting groove that is adapted to the shape of the isosceles triangle splicing plate, and the splicing surface of the isosceles triangle splicing mold is provided with an isosceles triangle hook and loop fastener mounting cavity. The cavity wall of the isosceles triangle hook and loop fastener mounting cavity is provided with isosceles triangle positioning posts arranged along the symmetry axis and the two legs of the isosceles triangle, which are used to insert into the positioning holes of the isosceles triangle hook and loop fastener to achieve positioning.

[0006] Preferably, the equilateral triangular adapter groove is an equilateral triangle structure, the side length of which is adapted to the side length of the equilateral triangular splicing plate, and the groove depth is adapted to the thickness of the equilateral triangular splicing plate.

[0007] Furthermore, the isosceles triangular adapter groove is an isosceles triangular structure, with the lengths of its two sides and the length of its base respectively matching the corresponding side lengths of the isosceles triangular splicing plate.

[0008] Furthermore, the equilateral triangular hook and loop fastener mounting cavity is shaped like an equilateral triangle, and its dimensions are adapted to the shape of the equilateral triangular hook and loop fastener.

[0009] In a further embodiment, the isosceles triangular hook and loop fastener mounting cavity is shaped like an isosceles triangle, and its dimensions are adapted to the shape of the isosceles triangular hook and loop fastener.

[0010] Based on the aforementioned scheme, the rough and hook surfaces of the equilateral triangle hook and loop fasteners and the isosceles triangle hook and loop fasteners are arranged in an intersecting manner, so that the equilateral triangle splicing mold and the isosceles triangle splicing mold can be joined by hook and loop fasteners. Beneficial effects

[0011] This Velcro-connected splicing board mold assembly, through the precise dimensional design of equilateral and isosceles triangular adapter slots, allows the splicing board to be quickly embedded into the mold for positioning, eliminating the need for complex alignment operations. The adhesive connection of the Velcro replaces the forceful operation of traditional plugging and snapping, allowing children to complete the splicing with just a light press and separate with a light pull, significantly reducing the difficulty of triangular splicing operations and enabling even young children to build independently. The equilateral triangular positioning posts are distributed in equilateral triangles, and the isosceles triangular positioning posts are distributed along the axis of symmetry and the two sides, ensuring accurate installation of the Velcro and uniform distribution of adhesive force during splicing. Compared with traditional connection methods, the splicing structure of this invention has a significantly reduced probability of loosening under normal impact from children's normal play (such as patting or light dropping), solving the problem of traditional triangular splicing easily falling apart. The equilateral and isosceles triangular splicing molds can be used alone to build pure triangular structures, or they can be used together to form composite irregular structures, covering various scenarios such as equilateral triangular three-dimensional shapes, isosceles triangular symmetrical shapes, and triangular composite shapes, meeting the diverse creative building needs of children.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] See Figures 1-11 A splicing panel mold assembly based on Velcro connection: The fitting and splicing between equilateral triangular splicing molds 1 The equilateral triangle splicing mold 1 has an equilateral triangle adapter groove 2 with an equilateral triangle structure, a side length of 8cm, and a groove depth of 0.4cm. It is precisely adapted to the shape of the equilateral triangle splicing plate with a side length of 8cm and a thickness of 0.5cm. The inner wall of the equilateral triangle adapter groove 2 is provided with fine stripes for anti-slip texture, which enhances the friction with the equilateral triangle splicing plate and prevents the splicing plate from sliding after being embedded.

[0016] The splicing surface of the equilateral triangular splicing mold 1 is provided with an equilateral triangular hook and loop fastener mounting cavity 3. The cavity is shaped like an equilateral triangle with a side length of 4cm and a depth of 0.3cm (slightly less than the thickness of the equilateral triangular hook and loop fastener, which is 0.4cm). Three equilateral triangular positioning posts 4 are distributed on the cavity wall, with a diameter of 0.3cm and a height of 0.2cm. They are evenly arranged in an equilateral triangle (spaced 2cm apart) and correspond one-to-one with the three positioning holes of the equilateral triangular hook and loop fastener (rough side). The hook and loop fastener is securely installed by inserting the positioning posts into the positioning holes. After installation, 0.1cm of the hook and loop fastener is exposed for pasting.

[0017] During assembly, the equilateral triangular splicing plate is embedded into the equilateral triangular fitting groove 2 of the equilateral triangular splicing mold 1, so that the edge of the splicing plate is tightly fitted with the groove wall. Since the equilateral triangular hook and loop fasteners are all set with a rough surface, an auxiliary equilateral triangular splicing mold 1 (with its hook and loop fasteners set with a hook surface) is required. Align the splicing surface of the rough surface mold with the three splicing surfaces of the hook surface mold respectively, and press gently. The rough surface of the hook and loop fasteners are tightly attached to the hook surface, forming a closed equilateral triangular three-dimensional structure (such as the base of a triangular tower).

[0018] With the precise positioning and anti-slip texture of the equilateral triangular adapter groove 2, the splicing board does not wobble. The equilateral triangular positioning post 4 ensures the accurate installation position of the Velcro and the uniform force on the Velcro. The impact resistance of the spliced ​​structure is improved. The probability of loosening when children pat or lightly drop it is less than 10%, which solves the problem of traditional triangular splicing being easy to fall apart. Moreover, the splicing operation does not require force to insert, and a 4-year-old child can complete it independently.

[0019] The fitting and splicing of the isosceles triangle splicing molds 5 The isosceles triangular adapter groove 6 of the isosceles triangular splicing mold 5 is an isosceles triangular structure with two sides of 6cm, a base of 5cm, and a groove depth of 0.4cm. It is adapted to an isosceles triangular splicing plate with two sides of 6cm, a base of 5cm, and a thickness of 0.5cm. The inner wall of the isosceles triangular adapter groove 6 is also provided with anti-slip texture to enhance the stability of the splicing plate.

[0020] The splicing surface of the isosceles triangle splicing mold 5 is provided with an isosceles triangle hook and loop fastener mounting cavity 7, which is shaped like an isosceles triangle (two sides are 4cm long and the base is 3cm long). The cavity wall is distributed with 3 isosceles triangle positioning posts 8: one post is located at the midpoint of the axis of symmetry of the isosceles triangle, and the other two posts are located at the midpoints of the two sides respectively. The diameter is 0.3cm, which is adapted to the positioning holes of the isosceles triangle hook and loop fastener (hook side). After the hook and loop fastener is installed, 0.1cm is exposed.

[0021] During assembly, take the isosceles triangle splicing mold 5 (with hook-and-loop fasteners) and the auxiliary isosceles triangle splicing mold 5 (with rough-textured fasteners). Insert the isosceles triangle splicing plate into the isosceles triangle fitting groove 6 of the hook-and-loop mold, and insert the splicing plate into the fitting groove of the rough-textured mold, so that the splicing surface (waist edge) of the hook-and-loop mold is aligned with the two splicing surfaces (waist edges) of the rough-textured mold. After pressing, the hook-and-loop fasteners are attached to form a symmetrical isosceles triangle structure (such as the slopes on both sides of a roof).

[0022] The 8 isosceles triangle positioning posts are distributed along the axis of symmetry and the two sides, which can adapt to the asymmetry of the isosceles triangle splicing board. The splicing position is precise, and the cross-set Velcro ensures a firm adhesion. The structure will not slide when placed at an angle after splicing. It solves the problems of complicated operation and inaccurate positioning of traditional isosceles triangle splicing. Children can easily build symmetrical shapes.

[0023] The assembly of equilateral triangle splicing mold 1 and isosceles triangle splicing mold 5 The equilateral triangle splicing mold 1 (with a rough surface for the Velcro) from Example 1 and the isosceles triangle splicing mold 5 (with a hook surface for the Velcro) from Example 2 are selected. The side length of the equilateral triangle splicing board is 8cm, and the two sides of the isosceles triangle splicing board are 6cm long and the base is 5cm long.

[0024] During assembly, the equilateral triangle splicing plate is inserted into the equilateral triangle splicing mold 1, and the isosceles triangle splicing plate is inserted into the isosceles triangle splicing mold 5, so that one splicing edge (side length 8cm) of the equilateral triangle splicing mold 1 is aligned with the bottom edge (length 5cm) of the isosceles triangle splicing mold 5. At this time, the equilateral triangle hook and loop fastener (rough side) and the isosceles triangle hook and loop fastener (hook side) come into contact. After pressing, the fastener is completed, forming a composite structure of "equilateral triangle + isosceles triangle" (such as the combination of the bottom of a tower and the side slope).

[0025] The two types of molds have cross-laid hook and loop fasteners (rough and hook sides) to enable cross-type splicing. The adapter slots restrict the displacement of the two splicing boards respectively, and the positioning posts ensure the accurate positioning of the hook and loop fasteners. The composite structure after splicing has good stability and can withstand external force pulling from multiple angles, expanding the possibilities of children's creative building and solving the problem of traditional irregular molds being difficult to match.

[0026] The equilateral triangle splicing mold 1 and the isosceles triangle splicing mold 5, through the precise positioning of the splicing plate by the adapter groove, the fixing of the position of the Velcro by the positioning post, and the cross-attachment of the Velcro, realize the convenient and stable connection of the triangle splicing plate, effectively solve the problems of inconvenient operation and unstable connection of existing triangle splicing, and improve the game experience and hands-on ability of children's splicing toys.

[0027] See Figures 1-11 A splicing panel mold assembly based on Velcro connection: The system includes a straight splicing mold 9 and an arc splicing mold 10. The straight splicing mold 9 is provided with a straight fitting groove 11, which fits the edge of the straight splicing plate. The splicing surface of the straight splicing mold 9 is provided with a straight hook and loop fastener mounting cavity 12. The opening of the straight hook and loop fastener mounting cavity 12 faces the splicing direction. Straight positioning posts 13 are distributed on the cavity wall for positioning by inserting the positioning holes of the straight hook and loop fastener. The straight splicing plate is installed through the straight fitting groove 11. The straight hook and loop fasteners fixed by the straight hook and loop fastener mounting cavity 12 and the straight positioning posts 13 connect the straight splicing plates by hook and loop fastener, solving the problems of inconvenient operation and poor stability of straight splicing plate connection.

[0028] The rough and hook surfaces of straight hook and loop fasteners, curved hook and loop fasteners, equilateral triangular hook and loop fasteners, and isosceles triangular hook and loop fasteners are arranged in an interlaced manner to ensure that the hook and loop fasteners can be glued together when any two molds are spliced.

[0029] The arc splicing mold 10 is provided with an arc-shaped adapter groove 14 to fit the arc splicing plate. The splicing surface of the arc splicing mold 10 is provided with an arc-shaped hook and loop fastener mounting cavity 15. The arc-shaped positioning post 16 on the cavity wall is used to fix the arc-shaped hook and loop fastener. After the arc splicing plate is embedded in the arc-shaped adapter groove 14, the arc splicing is achieved through the arc-shaped hook and loop fastener in the arc-shaped hook and loop fastener mounting cavity 15.

[0030] The mating and splicing between the straight-line splicing molds 9 The straight-line splicing mold 9 has a long strip-shaped fitting groove 11 with a length of 10cm, a width of 4cm, and a depth of 0.4cm. It precisely matches the edge of the straight splicing plate with a length of 10cm, a width of 4cm, and a thickness of 0.5cm. The splicing surface of the straight-line splicing mold 9 has a straight-line hook and loop fastener mounting cavity 12, which is rectangular in shape (length 8cm, width 2cm) and 0.3cm deep (slightly less than the thickness of the straight hook and loop fastener of 0.4cm). Three straight positioning posts 13 are evenly distributed along the length of the cavity wall, with a diameter of 0.3cm, a height of 0.2cm, and a spacing of 3cm. They correspond one-to-one with the three positioning holes of the straight hook and loop fastener (rough surface). The hook and loop fastener is securely installed by inserting the positioning posts into the positioning holes. After installation, 0.1cm of the hook and loop fastener is exposed for pasting.

[0031] During splicing, the straight splicing panel is embedded into the straight fitting groove 11 of the straight splicing mold 9, so that the edge of the splicing panel is tightly attached to the groove wall. Since the straight hook and loop fasteners are arranged in a cross pattern (one is a rough surface and the other is a hook surface), the splicing surfaces of the two molds are aligned along the length direction and gently pressed. The rough surface and hook surface of the hook and loop fasteners are tightly attached to form a straight extension structure (such as a castle wall).

[0032] With the precise positioning and anti-slip texture of the straight-line adapter groove 11, the splicing board does not wobble laterally. The straight-line positioning post 13 ensures the accurate installation position of the Velcro. The adhesive force is evenly distributed along the length direction, and the tensile strength of the structure after splicing is improved. There is no loosening at the connection when children pull the two ends. The technical features of "adapter groove positioning + positioning post fixing Velcro + Velcro pasting" solve the problems of traditional straight splicing requiring precise alignment and insertion and easy detachment.

[0033] The fitting and splicing between the arc-shaped splicing molds 10 The arc-shaped fitting groove 14 of the arc-shaped splicing mold 10 is designed according to the curvature of the arc splicing plate (curvature radius 15cm). The groove is 12cm long and 0.4cm deep, and it fits the arc splicing plate with a curvature radius of 15cm, a length of 12cm, and a thickness of 0.5cm. The inner wall of the arc-shaped fitting groove 14 is provided with anti-slip texture along the arc trajectory to enhance the fit with the arc splicing plate and prevent the splicing plate from sliding along the arc direction after being embedded.

[0034] The splicing surface of the arc-shaped splicing mold 10 is provided with an arc-shaped hook and loop fastener mounting cavity 15, which is distributed along the arc trajectory (length 10cm, width 2cm). The cavity wall is evenly distributed with arc-shaped positioning posts 16, with a diameter of 0.3cm and a height of 0.2cm, which are adapted to the positioning holes of the arc-shaped hook and loop fastener (hook side). After the hook and loop fastener is installed, 0.1cm is exposed for pasting.

[0035] During assembly, take the arc-shaped splicing mold 10 and embed the arc-shaped splicing plates into the arc-shaped adapter grooves 14 respectively. Since the arc-shaped hook and loop fasteners are arranged in a cross pattern, align the splicing surfaces of adjacent molds in turn (the rough surface and the hook surface alternately contact each other), and gently press to stick the hook and loop fasteners together, finally forming a closed arc-shaped structure.

[0036] The curved adapter groove 14 fits the curve of the splicing panel, and the anti-slip texture ensures stable installation of the curved splicing panel. The curved positioning posts 16 are distributed along the trajectory to ensure that the Velcro fits precisely with the curved splicing surface. After splicing, the curved structure is round and without misalignment. The shape adaptability of the curved adapter groove 14 and the precise positioning of the positioning posts solve the problem of unstable connection caused by angle deviation in traditional curved splicing.

[0037] The joint assembly of straight-line splicing mold 9 and curved splicing mold 10 The straight splicing mold 9 (with a rough surface for the Velcro) from Example 1 and the arc splicing mold 10 (with a hook surface for the Velcro) from Example 2 are selected. The length of the straight splicing board is 10cm and the radius of curvature of the arc splicing board is 15cm.

[0038] During assembly, the straight splicing panel is embedded into the straight splicing mold 9, and the curved splicing panel is embedded into the curved splicing mold 10, so that the splicing surface (end) of the straight splicing mold 9 is aligned with the splicing surface (end) of the curved splicing mold 10. At this time, the straight hook and loop fastener (rough side) contacts the curved hook and loop fastener (hook side), and after pressing, the pasting is completed, forming a smooth transition between the straight structure and the curved structure (such as the connection between the wall and the arch).

[0039] The Velcro on the two molds is arranged in a cross pattern of "rough side - hook side" to achieve cross-type splicing compatibility. The straight adapter groove 11 and the arc adapter groove 14 respectively restrict the displacement of the two splicing plates. The positioning post ensures that the Velcro is accurately attached. After splicing, the transition structure has no obvious gaps and has good resistance to external impact. This effect is achieved through the synergistic effect of the technical features of different molds, which expands the diversity of splicing shapes.

[0040] The fitting and splicing of equilateral triangular splicing mold 1 and straight-line splicing mold 9 The equilateral triangular splicing mold 1 (with hook and loop fastener) and the straight splicing mold 9 (with rough hook and loop fastener) from Example 1 are selected. The side length of the equilateral triangular splicing board is 8cm and the length of the straight splicing board is 10cm.

[0041] During assembly, the equilateral triangular splicing plate is embedded into the equilateral triangular fitting groove 2 of the equilateral triangular splicing mold 1, and the straight splicing plate is embedded into the straight fitting groove 11 of the straight splicing mold 9, so that one splicing edge of the equilateral triangular splicing mold 1 is aligned with the splicing surface of the straight splicing mold 9. The equilateral triangular hook and loop fasteners (hook surface) and the straight hook and loop fasteners (rough surface) come into contact and are pressed and pasted to form a combination structure of triangular roof and straight wall.

[0042] The equilateral triangular adapter slot 2 and the straight line adapter slot 11 respectively position the two types of splicing plates. The cross-set Velcro allows for stable adhesion. After splicing, the composite structure is subjected to uniform stress, which solves the problem of traditional triangular and straight line splicing requiring special connectors and reflects the synergistic value of different mold technology features.

[0043] The matching and splicing of isosceles triangular splicing mold 5 and arc-shaped splicing mold 10 The isosceles triangular adapter groove 6 of the isosceles triangular splicing mold 5 is an isosceles triangular structure with two sides of length 6cm, a base length of 5cm, and a groove depth of 0.4cm. It is adapted to the isosceles triangular splicing plate of the corresponding size. The isosceles triangular positioning posts 8 of the isosceles triangular hook and loop fastener mounting cavity 7 are distributed along the axis of symmetry and the two sides to fix the isosceles triangular hook and loop fastener (hook side).

[0044] Using the arc-shaped splicing mold 10 (with a rough surface for the Velcro) from Example 2, the arc-shaped splicing board has a radius of curvature of 15cm. During splicing, the isosceles triangular splicing board is embedded into the isosceles triangular fitting groove 6 of the isosceles triangular splicing mold 5, and the arc-shaped splicing board is embedded into the arc-shaped fitting groove 14 of the arc-shaped splicing mold 10, so that the bottom splicing surface of the isosceles triangular splicing mold 5 is aligned with the end splicing surface of the arc-shaped splicing mold 10. The isosceles triangular Velcro (hook surface) contacts and presses the arc-shaped Velcro (rough surface). After the pasting is completed, a combination structure of isosceles triangular decoration and arc-shaped arch is formed (such as castle entrance decoration).

[0045] The isosceles triangular adapter groove 6 restricts the displacement of the splicing plate through anti-slip texture, the arc-shaped adapter groove 14 ensures the stability of the arc-shaped splicing plate, and the positioning post ensures the accurate installation position of the Velcro. The cross-attachment of the Velcro of the two molds achieves a stable connection, which solves the problem of the complexity of traditional irregular splicing operations. This effect is derived from the technical features of "adapter groove positioning + positioning post fixing + Velcro cooperation".

[0046] The fitting and splicing of isosceles triangle splicing mold 5 and equilateral triangle splicing mold 1. Use equilateral triangle splicing mold 1 (with hook and loop fasteners on the rough side) and isosceles triangle splicing mold 5 (with hook and loop fasteners on the hook side). The side length of the equilateral triangle splicing board is 8cm, and the two sides of the isosceles triangle splicing board are 6cm long.

[0047] During assembly, the splicing panels are embedded into the corresponding mold's fitting slots, aligning the waist-side splicing surface of the isosceles triangular splicing mold 5 with the side-side splicing surface of the equilateral triangular splicing mold 1. The Velcro surface is then pressed and pasted onto the hook side to form an asymmetrical triangular combination structure (such as the connection between the side of a tower and the top of a triangle).

[0048] The two types of triangular molds have matching slots that precisely position the splicing plates, and the positioning posts ensure the accurate placement of the Velcro. The cross-attached Velcro securely connects different triangular structures, expanding the creative possibilities for splicing irregular triangular shapes.

[0049] The joint assembly of the arc-shaped splicing mold 10, the equilateral triangle splicing mold 1, and the straight-line splicing mold 9. Align the two bottom sides of the trapezoidal splicing plate and embed it into the equilateral triangle adapter groove 2 of the equilateral triangle splicing mold 1. The anti-slip texture of the groove wall closely fits the edge of the trapezoidal plate to prevent lateral sliding. Align the two top sides of the trapezoidal splicing plate and embed it into the isosceles triangle adapter groove 6 of the isosceles triangle splicing mold 5. Through the precise size matching between the groove and the edge of the trapezoidal plate, offset-free positioning is achieved.

[0050] Will Figure 7The side of the rectangular assembly panel to be assembled (with hook-and-loop fasteners) is aligned with the corresponding side of the trapezoidal assembly panel (with rough-surface hook-and-loop fasteners). The positioning holes and positioning posts on the edges of the assembly panels work together to ensure that the rough-surface hook-and-loop fasteners of the trapezoidal assembly panel completely cover the hook-and-loop fasteners of the rectangular assembly panel, ensuring no misalignment. Gently press the joint surfaces of the trapezoidal and rectangular assembly panels to make the rough-surface hook-and-loop fasteners fit tightly together. The connection between the two assembly panels is achieved solely through the adhesive force of the hook-and-loop fasteners, without the need for plugs, clips, or other connecting structures. No force is required during operation, making it easy for young children to complete.
