Description

Technical Field

[0001] This utility model relates to the field of building block toy flower technology, and more specifically, to a building block flower structure. Background Technology

[0002] In the current building block toy market, building block flowers, as a creative and fun type of toy, are loved by a wide range of consumers, especially children and building block enthusiasts. However, existing building block flowers have many shortcomings in terms of design and function, which limit their further development and the improvement of user experience.

[0003] Most existing building block flowers are static structures, connecting petals and calyxes through simple interlocking. The connection between petals and calyxes is not stable enough, and petals are prone to falling off during play. Furthermore, the petals cannot open or close, lacking the fun of dynamic changes.

[0004] Even though some building block flowers have petal opening and closing functions, the operation is often not flexible or convenient enough to meet the diverse play needs of users. While some building block flowers do have petal opening and closing functions, these require manually prying open each petal individually. This operation is cumbersome, inflexible, and inconvenient, making it difficult for children to operate. Furthermore, existing petal opening and closing structures are not very stable; petals are prone to loosening, falling off, or being damaged during repeated opening and closing, affecting the normal use of the toy, reducing the enjoyment of play, and posing a risk of lost parts and accidental ingestion by children. Therefore, they fail to meet users' needs for convenient and safe play.

[0005] In view of this, given the numerous problems existing in the petal opening and closing, fixing methods, and assembly structures of existing building block flowers, developing a new type of building block toy flower with a petal structure that allows for convenient opening and closing is of great practical significance. It can effectively solve the problems of existing products, improve user experience, and expand the market space for building block toys. Utility Model Content

[0048] First embodiment:

[0049] During installation, align the combination positioning post 14 of the inner layer connecting component 1 with the combination positioning hole 25 of the outer layer connecting component 2 and insert it into the combination positioning hole 25. This allows the combination hook 15 of the inner layer connecting component 1 to slide along the inner wall of the outer layer connecting component 2 and engage with the combination buckle at the upper end of the outer layer opening and closing groove 23.

Then, clamp the opening and closing rotation groove 41 onto the outer layer combination ring 21 and complete the limiting by the outer layer limiting protrusions 22 on both sides. The installation of the opening and closing petal part 4 is also completed.

[0050] During the flowering operation, hold the multi-layer flower core connecting part and rotate the flower stem part 5 to drive the opening and closing core rod 3 to rotate. The opening and closing core rod 3 rises upward with the cooperation of the opening and closing lifting external thread 33 and the opening and closing internal thread 24. The inner layer linkage protrusion ring 31 and the outer layer linkage protrusion ring 32 of the opening and closing core rod 3 push the opening and closing linkage groove 42 upward to make the opening and closing rotation groove 41 of the opening and closing petal part 4 flip outward along the inner layer combination ring 11 and the outer layer combination ring 21.

The inner layer linkage protrusion ring 31 and the outer layer linkage protrusion ring 32 of the opening and closing core rod 3 pull down and push the opening and closing linkage slot 42 to make the opening and closing rotation groove 41 of the opening and closing petal part 4 rotate inward along the inner layer combination ring 11 and the outer layer combination ring 21. At the same time, the flower bud component 6 at the top of the opening and closing core rod 3 descends and is covered by the opening and closing petal part 4, realizing the closure of the opening and closing petal part 4.

Three inner petal components are installed on the inner layer combination ring 11, and six outer petal components are installed on the outer layer combination ring 21. The outer petal components include a first outer petal component and a second outer petal component installed at intervals on the outer layer combination ring 21. The second outer petal component is located outside the first outer petal component.

[0054] During the multi-layer flowering operation, hold the multi-layer flower core connecting part and rotate the flower stem part 5 to drive the opening and closing core rod 3 to rotate. The opening and closing core rod 3 rises upward under the cooperation of the opening and closing lifting external thread 33 and the opening and closing internal thread 24. The inner layer linkage protrusion ring 31 and the outer layer linkage protrusion ring 32 of the opening and closing core rod 3 push the opening and closing linkage slot 42 upward. The outer layer linkage protrusion ring 32 combines with the opening and closing rotation slot 41 of the opening and closing petal part 4 to make the first outer petal component and the second outer petal component flip outward along the outer layer combination ring 21. The inner layer linkage protrusion ring 31 combines with the opening and closing rotation slot 41 of the opening and closing petal part 4 to make the inner petal component flip outward along the inner layer combination ring 11. The inner petal component, the first outer petal component and the second outer petal component gradually open in sequence. At the same time, the flower bud component 6 at the top of the opening and closing core rod 3 rises and is displayed. After the rising limit protrusion ring 36 abuts against the lower end of the opening and closing internal thread 24, the rising of the opening and closing core rod 3 is restricted, thus completing the multi-layer flowering operation.

[0055] Third embodiment:

[0056] This embodiment is similar to the first embodiment, except that the bud component 6 and the opening / closing core rod 3 are detachable and replaceable. The flower stem portion 5 has a flower and leaf combination hole 52 in the middle, and a flower and leaf connecting component 53 is installed inside the flower and leaf combination hole 52. Both ends of the flower and leaf connecting component 53 have flower and leaf combination protrusions 54. The flower and leaf combination protrusions 54 can be combined with combination holes of different styles of flowers and leaves to install different styles of flowers and leaves. Users can remove the bud component 6 and replace it with other bud components 6 of different specifications and styles according to different assembly ideas. Simultaneously, they can remove the flowers and leaves from the flower and leaf connecting component 53, replace and install other flowers and leaves of different specifications and styles on the flower and leaf combination protrusions 54, and adjust the direction of the flowers and leaves to form various flower structures.
