Description

Technical Field

[0001] This utility model relates to the field of game toy technology, and in particular to a mortise and tenon building block. Background Technology

[0002] Building blocks are a common educational toy for children, typically composed of cubic wooden or plastic blocks. Their surfaces can be decorated with letters, pictures, and other elements, and they are used to develop children's intelligence through building activities. Current building blocks mainly employ the following assembly methods: 1. Directly stacking regular blocks without actual connections between them; 2. Using magnetic attraction to allow blocks to adhere to each other; 3. Using a mortise and tenon structure to design regular blocks, with a fixed distribution of the mortise and tenon surfaces (e.g., one side is a tenon and the rest are mortises, or opposite sides have separate mortise and tenon surfaces).

[0003] In existing technologies, building blocks using various splicing methods generally suffer from structural instability after assembly, easily falling apart under external forces; while structurally robust building blocks are often complex in design and difficult to disassemble. The limited splicing methods of existing building blocks restrict functional expandability, failing to meet users' needs for a combination of diversity and practicality. Due to structural design limitations, these building blocks are difficult to apply to broader fields such as education and creative displays, and lack modular and reusable design concepts. For example, with mortise and tenon joints, once multiple blocks are connected by tenons, adjacent blocks cannot be connected. The mortise and tenon structure on the building blocks is fixed during production and cannot be adjusted during use, lacking expandability and flexibility. Furthermore, idle building blocks, lacking practical value, mostly occupy household space or are discarded, leading to resource waste and environmental pollution. These problems not only reduce the use value of building blocks but also restrict user experience and product lifecycle. Utility Model Content

[0004] The purpose of this utility model is to provide a mortise and tenon building block to address the shortcomings of the existing technology.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A mortise and tenon building block includes a main body, characterized in that: a first mortise and a second mortise are provided on the main body, and a first tenon and a second tenon respectively cooperate with the first mortise and the second mortise. The first tenon includes a tenon body and an annular mortise. The annular mortise is symmetrically arranged on both ends of the tenon body. The shape of the tenon body cooperates with the shape of the first mortise. The shape of the second tenon cooperates with the shape of the second mortise and the annular mortise. When the first tenon is inserted into the first mortise, the second tenon is inserted from the second mortise, so that the inner end of the second tenon can abut against and engage in the annular mortise.

[0007] Furthermore, the first tenon also includes an annular tenon, which is located at the center of the side of the tenon body. The first tenon has an symmetrical structure with the annular tenon as the axis. A first countersunk hole is provided at the edge of the first mortise. The shape of the annular tenon matches the shape of the first countersunk hole. When the first tenon is inserted into the first mortise, the annular tenon abuts and engages with the first countersunk hole, thus limiting the position of the first tenon.

[0008] Furthermore, the thickness of the annular tenon is twice the depth of the first countersunk hole.

[0009] Furthermore, the length of the second tenon is equal to the distance from the bottom of the annular mortise to the surface of the block body. When the inner end of the second tenon abuts against the annular mortise, the outer end face of the second tenon is flush with the outer surface of the block body. A second countersunk hole is provided at the edge of the second mortise for removing the second tenon.

[0010] Furthermore, the second countersunk hole is elliptical in shape.

[0011] Furthermore, the tenon body of the first tenon is a cylindrical structure, and the first mortise is a circular mortise.

[0012] Furthermore, both the second mortise and the second tenon are square structures.

[0013] Furthermore, a square through hole is provided on the tenon body.

[0014] Furthermore, the shapes of the building blocks include cubes, cuboids, cylinders, spheres, and irregular shapes.

[0015] Furthermore, the main body of the building block adopts a hollow structure made of plastic.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. The traditional tenon structure of building blocks is separated from the main body, and all surfaces of the main body are designed with mortises. Simultaneously, the tenons are designed as independent, symmetrical cylindrical structures with annular mortises at both ends. The two ends of these independent tenons are used to connect two main body blocks, allowing any surface of each main body block to establish a tenon-and-mortise connection with the surfaces of other main body blocks. By increasing the number of connection points, the final assembled structure is more robust.

[0018] 2. The connection point between the main body of the building blocks and the tenon joint is exceptionally strong and cannot be torn apart without violent force. The main bodies of the building blocks can still rotate relative to each other while connected, making them impossible to disassemble and allowing for flexible angle adjustments. Through the mutual rotation and orientation changes of the main bodies of the building blocks, a wider variety of splicing shapes can be created.

[0019] Other features and advantages of this invention will be set forth in the following description or may be learned by practicing this invention. Attached Figure Description

[0027] To enhance understanding of this utility model, we will now describe it in further detail with reference to the accompanying drawings. This embodiment is only used to explain this utility model and does not constitute a limitation on the scope of protection of this utility model.

[0028] In the description of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0030] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," "fixing," and "setting," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] like Figure 1-4 The diagram illustrates a specific embodiment of a mortise and tenon building block. It includes a main block body 1, a first tenon 2, and a second tenon 3.

[0032] like Figure 1 As shown, the main body 1 of the building block has a first mortise 11 and a second mortise 12. The first mortise 11 and the second mortise 12 are used to mate with the first tenon 2 and the second tenon 3, respectively. The shape of the main body 1 of the building block can be various, such as a cube, cuboid, cylinder, sphere, or irregular shape. Here, we take the cube, which is currently the most common shape for building block bodies, as an example. The side length of the main body 1 is 3 centimeters, and it is made of plastic.

[0033] When manufacturing the main body 1 of the building block, it is made into a hollow structure through injection molding. Five sides are molded in one go, and then the remaining side is injection molded. The two sides are then welded together using an ultrasonic welding machine to form a hollow cube structure. This manufacturing method saves materials and ensures a smooth, beautiful, and deformation-free product appearance. It also solves the problem that plastic products often deform significantly due to excessive material thickness and inconsistent thermal shrinkage caused by short injection molding times.

[0034] All six sides of the building block body 1 have the same structure, with a first mortise 11 extending through the center of each of the six sides. The diameter of the first mortise 11 is one-third of the side length of the building block body 1. Four second mortise 12s are provided on each side of the building block body 1, surrounding the first mortise 11s. The second mortise 12s are through square mortise 12s, and the distance from the edge of the second mortise 12 is equal to the thickness of a single side of the building block body 1. For example, if the thickness of a single side of the building block body 1 is 3 mm, then the distance from the second mortise 12 to the nearest edge is also 3 mm.

[0035] Preferably, a first countersunk hole 13 is provided on the edge of the first mortise 11. The first countersunk hole 13 is circular and is used to limit the positioning of the first tenon 2. A second countersunk hole 14 is provided on the edge of the second mortise 12. The second countersunk hole 14 is elliptical and is used to help to pick up the second tenon 3.

[0036] like Figure 2 As shown, the first tenon 2 includes a tenon body 21 and an annular mortise 22. The tenon body 21 is a cylindrical structure. The annular mortise 22 is symmetrically arranged on both sides of the tenon body 21. The cross-sectional dimensions of the tenon body 21 are the same as the dimensions of the first mortise hole 11. The length of the tenon body 21 is 2 / 3 of the side length of the block body 1.

[0037] Preferably, an annular tenon 23 is provided at the center of the side of the tenon body 21. The diameter of the annular tenon 23 is the same as the diameter of the first countersunk hole 13, and the thickness of the annular tenon 23 is twice the depth of the first countersunk hole 13. Thus, when the first tenon 2 is half-inserted into the first mortise 11, half of the protruding annular tenon 23 abuts and engages with the first countersunk hole 13, restricting further insertion of the first tenon 2. The other half of the first tenon 2 is connected to the other block body 1 in the same way, with the other half of the annular tenon 23 also restricting further insertion of the first tenon 2. In this way, when the two block bodies 1 are connected, their surfaces can fit tightly together.

[0038] Preferably, a square through hole 24 is provided on the tenon body 21. This can save materials and reduce the thickness of the product, thus avoiding deformation that could affect the appearance of the building blocks.

[0039] like Figure 3 As shown, the second tenon 3 is a cuboid structure, and its shape and size match the second mortise 12. The width of the annular mortise 22 is the same as the thickness of the second tenon 3. When the first tenon 2 is inserted into the first mortise 11, the second tenon 3 is inserted from the second mortise 12, so that the inner end of the second tenon 3 can abut against and be engaged in the annular mortise 22.

[0040] Preferably, the length of the second tenon 3 is equal to the distance from the bottom of the annular mortise 22 to the surface of the block body 1. When the inner end of the second tenon 3 abuts against the annular mortise 22, the outer end face of the second tenon 3 is flush with the outer surface of the block body 1. A second countersunk hole 14 is provided at the edge of the second mortise 12, and a height difference is formed between the second countersunk hole 14 and the second tenon 3 to facilitate the removal of the second tenon 3.

[0041] like Figure 4As shown, when the block body 1 is connected to the first tenon 2, half of the first tenon 2 is inserted into any of the first mortises 11 of the block body 1 until the protruding annular tenon 23 is engaged with the first countersunk hole 13. Then, a second tenon 3 is fully inserted into the second mortise 12 in the opening direction of the annular mortise 22 until the inner end of the second tenon 3 abuts against the bottom of the annular mortise 22 and the outer section of the second tenon 3 is flush with the surface of the block body 1. This not only secures the first tenon 2 to prevent it from coming out, but also ensures that it is not pushed outward under the influence of external force when the second tenon 3 is rotated or pulled, thus preventing the assembled blocks from falling apart.

[0042] like Figure 5 As shown, the other half of the first tenon 2 is connected to other building block bodies 1 in the same way. Because the first tenon 2 is round, there are no gaps between the building block bodies 1, and they can rotate and pull on each other without any parts falling out and causing the assembled blocks to disintegrate. Each face of a building block body 1 can be connected to other building block bodies 1 using the first tenon 2 and the second tenon 3, forming a structure like... Figure 6 The structure shown.

[0043] These building blocks not only allow children to play with them as stacking blocks, but also as quick-connect blocks. Their mortise and tenon structure simplifies assembly, increases the number of joints, and allows for more diverse shapes. The structure is robust and easy to disassemble. The simple assembly method, coupled with its functional expandability, modular and reusable design, enriches the user experience and extends the product lifecycle. Most importantly, the robust structure meets users' needs for a combination of versatility and practicality. Specifically, the independent tenon design allows for free connection of all surfaces of the building blocks, greatly improving the flexibility and complexity of spatial combinations. Its unique "robust yet rotatable" connection characteristic ensures the structural strength against separation while providing the possibility of dynamic angle adjustment, significantly enhancing interactive fun and structural expressiveness. Furthermore, the relative rotation and orientation conversion capabilities between the building blocks break through the limitations of traditional single-stacking building blocks, easily constructing various curved surfaces, hinged joints, and deformable structures, greatly expanding the creative space for design. This allows the building block system to meet the simple stacking needs of young children as well as the complex creative constructions of more advanced players, effectively extending the product's applicable age range and usage depth. Furthermore, when not in use, the blocks can be assembled into a sturdy box, picture frame, stool, pen holder, small bookshelf, chest, and other practical household items.

However, the above content does not limit the protection scope of this utility model. Any equivalent changes or modifications made in accordance with the spirit and essence of this utility model shall fall within the protection scope of this utility model.
