Description

Technical Field

[0001] The utility model relates to the technical field of building blocks, in particular to a mortise and tenon structure connecting tenon piece used in building blocks. Background Art

[0002] Building blocks are usually cubic solid toys of wood or plastic, usually decorated with letters or pictures on each surface, allowing different arrangements or construction activities. Building blocks come in various styles, can develop children's intelligence, and can be assembled into houses, various animals, etc.

[0003] Given that existing building block components on the market use traditional uniaxial joints, building blocks can only be assembled sequentially from one dimension, limiting the degree of assembly freedom. Furthermore, due to stress concentration, uniaxial joints make it difficult to evenly distribute external loads, making the assembled structure more susceptible to deformation.

[0004] Therefore, improvements need to be made to this. Utility Model Content

[0005] The technical problem solved by the present invention is to address the defects existing in the above-mentioned prior art and provide a mortise and tenon structure connecting tenon for building blocks to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is as follows: A mortise and tenon structure connecting tenon used for building blocks, comprising: a first connector, the first connector is in the shape of an elongated strip, and the two ends of the first connector can be configured to connect building block units; a second connector, there are more than one, the second connector is fixed on the first connector, the second connector is in the shape of an elongated strip, and the two ends of the second connector can be configured to connect building block units.

[0007] Furthermore, the first connector is a dovetail joint.

[0008] Furthermore, the second connector is a dovetail joint.

[0009] Furthermore, the first connector and the second connector are arranged perpendicular to each other.

[0010] Furthermore, the first connector is provided with a first groove portion that is recessed inward.

[0011] Furthermore, the second connector is provided with a second groove portion that is recessed inwardly.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. Stability of cross structure and stress dispersion mechanism.

[0014] The cross dovetail structure is preferred. Unlike ordinary dovetails, the cross structure is adopted mainly because the cross structure has a good ability to resist shear stress and is more resistant to plastic deformation under such forces than other structures. The unique center connection design makes the moment or torque under the four-end force more evenly distributed compared to ordinary dovetails, and the force curve under different lever arms is also relatively flat, with a stronger ability to disperse force. The cross dovetail structure effectively disperses external forces through the cross structure, avoiding the stress concentration phenomenon of traditional uniaxial connection methods, achieving uniform dispersion of external loads, thereby enhancing the compression, bending, and torsional performance of the building block structure and significantly improving the overall structural strength.

[0015] 2. Multi-axial connection characteristics.

[0016] Unlike other dovetail joints, which can only be assembled from a single direction, the cross dovetail joint structure allows for multi-directional assembly. While ordinary dovetail joints can only be assembled sequentially from one dimension (one axis), the cross joint structure differs in that it adds another dimension (another axis) to the original one, allowing for more combinations and options in terms of the direction and surface of the connection, greatly increasing the flexibility and construction possibilities of the building block units.

[0017] 3. High elasticity, high precision and beautiful integrated design.

[0018] The hollow dovetail design, combined with a precise mortise and groove structure, achieves highly flexible and precise connections between the building blocks. This hollow design reduces the weight of the building blocks while increasing their elasticity, allowing for a tight fit with other components or the inner wall of the groove, increasing the load-bearing surface and effectively preventing loosening and deformation. Furthermore, the unique shape of the dovetail creates an aesthetically pleasing pattern after assembly, enhancing the overall aesthetics of the building blocks. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The present invention will be further described in detail below with reference to the accompanying drawings.

[0024] The embodiments described with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application. In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be construed as limiting the present application. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present application, "several" or "multiple" means two or more, unless otherwise specifically defined. In this application, unless otherwise expressly specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be interpreted broadly. For example, they can refer to fixed, removable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; or internal communication between two components. A person skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances. In this application, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or the first and second features being in contact through another feature between them. Furthermore, "above," "above," and "above" a first feature may include the first feature being directly above or diagonally above the second feature, or simply indicate that the first feature is at a higher level than the second feature. "Below," "below," and "below" a first feature may include the first feature being directly above or diagonally above the second feature, or simply indicate that the first feature is at a lower level than the second feature.

[0025] In view of the technical problems recorded in the background technology, such as Figure 1-2 As shown, a mortise and tenon structure connecting tenon for building blocks is provided, comprising: a first connector 1, the first connector 1 is in the shape of an elongated strip, and the two ends of the first connector 1 can be configured to connect building block units; there are more than one second connectors 2, the second connectors 2 are arranged on the first connector 1, the second connector 2 is in the shape of an elongated strip, and the two ends of the second connector 2 can be configured to connect building block units.

[0026] In specific use, external building block units can be connected to the two ends of the first connector 1 and the second connector 2 to construct the required style structure, realize the splicing of multiple building block units, meet specific building block assembly requirements, enrich the assembly methods, and increase interest.

[0027] Preferably, in implementation, the first connector 1 and the second connector 2 are in a cross structure, which can of course also be a cross structure at other angles, and a cross dovetail structure is adopted. Different from ordinary dovetails, the cross structure is adopted mainly because the cross structure has a good ability to resist shear stress, and its resistance to plastic deformation under such forces is higher than that of other structures. The unique center connection design makes the moment or torque under the four-end force more evenly distributed compared to ordinary dovetails, and the force curves under different force arms are also relatively flat, and the ability to disperse force is stronger. The cross dovetail structure effectively disperses external forces through the cross structure, avoids the stress concentration phenomenon of the traditional uniaxial connection method, and achieves uniform dispersion of external loads, thereby enhancing the compression, bending and torsion resistance of the building block structure and significantly improving the overall structural strength.

[0028] On the other hand, reference Figure 3 As shown, the cross dovetail structure is different from other dovetail joints, which can only be assembled from a single side in the same direction. Instead, it can be assembled in multiple directions. Ordinary dovetail joints can only be assembled in a sequential order from one dimension (one axis), but the cross structure is different in that it adds another dimension (another axis) to the original one, allowing for more combinations and options in the direction and surface of the connection, greatly improving the combination flexibility and construction possibilities of the building block units.

[0029] Specifically, the first connector 1 is a dovetail joint. The second connector 2 is a dovetail joint.

[0030] The external building block unit is correspondingly set to a dovetail groove structure. When connected, the dovetail tenon of the first connector 1 or the dovetail tenon of the second connector 2 is connected to the dovetail groove structure of the building block unit to improve the stability of the assembly. Of course, the first connector 1 and the second connector 2 can be triangular prisms or quadrangular prisms with the same or equivalent assembly structure.

[0031] Specifically, the first connector 1 and the second connector 2 are an integrated structure, which can increase structural strength and facilitate production.

[0032] Preferably, the first connector 1 and the second connector 2 are arranged perpendicular to each other.

[0033] Furthermore, the first connecting body 1 is provided with a first groove portion 3 that is recessed inwards. The second connecting body 2 is provided with a second groove portion 4 that is recessed inwards.

[0034] The hollow dovetail joint design of the first connector 1 and the second connector 2, combined with a precise tongue-and-groove structure, achieves highly flexible and precise connection between the building block units. This hollow design reduces the connector's weight while increasing its elasticity, facilitating a tight fit with other rubber components or the inner wall of the groove, increasing the load-bearing surface and effectively preventing loosening and deformation. Furthermore, the unique shape of the dovetail joint creates an aesthetically pleasing pattern after assembly, enhancing the overall aesthetics of the building block.

[0035] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
