Description

Technical Field

[0001] This utility model belongs to the field of amusement facility technology, and in particular relates to an outdoor building block system. Background Technology

[0002] With increasing emphasis on outdoor educational activities for children, outdoor building blocks, as products that combine entertainment and education, are experiencing continuous market demand growth. A Chinese patent application (CN202221378639.X) discloses an outdoor building block system comprising several blocks and several connectors. Each block has connecting holes on its side. Each connector includes two insertion parts and at least one limiting part. One end of each insertion part is connected to the other, and the other end connects to the connecting holes of two adjacent blocks. The limiting part is positioned on the insertion part and abuts against the block to prevent the insertion part from penetrating further into the connecting hole. By using the insertion parts at both ends of the connector to connect with the connecting holes of adjacent blocks, several blocks can be assembled together.

[0003] However, this technical solution still has many shortcomings and cannot fully meet the increasingly diverse needs of users. For example: 1. Regarding the flexibility of block connections, the connection method is relatively fixed, relying on connectors of specific shapes (cylindrical insertion parts and cylindrical connection holes) to match the block connection holes. 2. From the perspective of functional expansion, although the existing solution includes decorative parts and connecting tubes, the limitations of its connection method and block interface design make it difficult to effectively combine with other functional components. For example, it is not easy to add components with movement and rotation functions, making it difficult to achieve the transformation from static building to dynamic application. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an outdoor building block system to meet the needs of users.

[0005] To achieve the above objectives, this utility model provides an outdoor building block system, comprising a plurality of building block components, each building block component including at least one of a boss structure and a connecting structure;

[0006] The boss structure includes a reference plane and a boss that protrudes vertically from the reference plane to ensure the uniqueness of the insertion direction and avoid misalignment. The boss is provided with an insertion hole.

[0007] The connection structure includes a mating plane, which is adapted to fit the reference plane;

[0008] The connection structure can be selected from any of the following configurations:

[0009] First configuration: The connecting structure includes a cavity or opening disposed on the mating plane, the cavity and opening being adapted to engage with the boss;

[0010] Second configuration: The connection structure includes a pin disposed on the mating plane, the pin being adapted to be inserted and removed from the socket;

[0011] Third configuration: The connection structure includes both the opening disposed on the mating plane and the pin surrounding the opening.

[0012] Preferably, the cavity is recessed inward in a direction perpendicular to the reference plane; the opening is through-hole in a direction perpendicular to the reference plane.

[0013] Preferably, the building block component includes a block-shaped component, which comprises a set of parallel horizontal surfaces and a plurality of circumferential surfaces vertically supported between the horizontal surfaces, wherein:

[0014] One of the horizontal surfaces includes the boss structure, and the other horizontal surface includes the connecting structure; each of the circumferential surfaces includes the connecting structure.

[0015] It is understood that the two block components can be stacked vertically by the cooperation of the horizontal plane, and the two block components can also be connected laterally or longitudinally by the cooperation of the horizontal plane and the circumferential plane.

[0016] Preferably, the connecting structure in the block component is the third configuration, wherein: the pins are T-shaped, the sockets are cross-shaped, and a single socket can accommodate two pins simultaneously. The unique shape of the T-shaped pins allows them to form effective restraint in both the horizontal and vertical directions when mated with the cross-shaped socket. The ability to accommodate two T-shaped pins simultaneously in a single cross-shaped socket significantly increases the contact area and friction, further enhancing the connection strength.

[0017] Preferably, the block-shaped component includes:

[0018] Type A block-shaped component, which has a cubic structure;

[0019] Type B block components are rectangular in shape and are formed by connecting several Type A block components in parallel. The Type B block components have several independent or interconnected openings.

[0020] The block-shaped component supports, but is not limited to, the following combinations:

[0030] As a preferred option: n=2.

[0031] Preferably, the semi-cylindrical component further includes two columnar grooves that extend through it along its axial direction.

[0032] Preferably, the outdoor building block system further includes columnar connecting members and columnar traveling members, wherein the columnar connecting members include connecting columns disposed at both ends thereon, and the columnar traveling members include connecting columns and rollers that can rotate omnidirectionally about their axes.

[0033] A columnar groove is provided at the corner of the mating plane and / or at the corner of the bottom of the cavity, and the columnar groove is inserted and pulled into the connecting post.

[0034] As a preferred embodiment, a columnar groove or an insertion hole is provided at the center of the bottom of the concave cavity. The above design adds a support point in the vertical direction, thereby improving the anti-tipping ability of the tall structure.

[0035] Preferably, when the insertion hole is cross-shaped, the central area of ​​the insertion hole can be used to insert the columnar connecting member or the columnar walking member. The central part of the cross-shaped insertion hole is reused (for inserting columnar members), which improves the space utilization of the building block components.

[0048] The beneficial effects of this utility model are:

[0049] 1. By directly setting at least one of the boss structure and connection structure on the building block components, the number of connectors is reduced, the assembly steps are simplified, and a tighter and more direct fit between the building block components is achieved. Furthermore, by setting the boss structure as the standard male end and simultaneously setting three configurations of connection structure as selectable female ends to adapt to the standard male end, the boss structure can be reused, forming a variety of plug-in connection methods.

[0050] 2. Diverse building block components (block components, wide plate components, right triangle components, hemispherical components, semi-cylindrical components, etc.) provide a wealth of basic elements for building, greatly enriching the possibilities of construction. Block components, as basic units, are designed with different specifications such as Type A and Type B, and are equipped with dual interfaces, supporting multiple combination methods, breaking through the traditional unidirectional stacking limitations, and realizing free expansion in three-dimensional space.

[0051] 3. By setting columnar grooves as standard female ends, the connection methods and combination types can be expanded through columnar connectors. For example, the connection between two connection structures can be realized through columnar connectors. Static block components can also be quickly converted into mobile units through columnar walking units, expanding outdoor game scenarios. Attached Figure Description
