[0017] KEY

[0018] The building block 1 has a connecting hole, the building block connecting piece 2 has a connecting joint, the through hole 3, the blind hole 4, the end of the connecting hole 5, the through hole 6 with the same inner diameter, the through hole 7 with the protrusion, the protrusion 8 of the inner wall of the through hole, the end of the connecting joint 9, the building block connecting piece 10 without the ring-shaped protrusion, the cylindrical building block connecting piece 11, the arc-shaped building block connecting piece 12, and the ring-shaped protrusion 13. DETAILED DESCRIPTION

[0019] The present application will be described in detail below in combination with the drawings and embodiments, and the content of the present application is not limited to the following embodiments.

[0020] A modular connection structure, such as Figure 1 As shown, the system includes at least a block 1 with a connecting hole and a block connector 2 with a connecting joint. The dimensions of the connecting hole and the connecting joint are matched. The connecting hole is either a non-through blind hole 4 or a through hole 3. The end 5 of the connecting hole located on the outer surface of the block is funnel-shaped. When the connecting hole is a non-through blind hole, the outer diameter of the connecting joint is smaller than the inner diameter of the blind hole. When the connecting hole is a through hole, both ends of the connecting hole are funnel-shaped, and the inner diameter of the through hole can be consistent. The through hole 6 with consistent inner diameter allows the connecting joint to pass through completely for connection. A protrusion can also be provided in the middle of the inner wall of the through hole. The outer diameter of the connecting joint is smaller than the inner diameter of the through hole, and the outer diameter of the connecting joint is larger than the inner diameter of the protrusion 8 on the inner wall of the through hole. The connecting joint cannot pass completely through the through hole 7 with the protrusion, thus limiting the insertion depth of the connecting joint into the connecting hole. The connecting joint includes at least an end that can be inserted into the connecting hole, and the end 9 of the connecting joint is frustum-shaped.

[0021] Furthermore, the building block has one or more connecting holes, and the building block connector has one or more connecting joints.

[0022] The structure of the building block connector is as follows Figure 2 As shown, Figure 2 From left to right, the three types of building block connectors are: a block connector 10 without annular protrusions, a cylindrical block connector 11 with annular protrusions, and an arc-shaped block connector 12 with annular protrusions. The annular protrusions 13 can be positioned near the end of the connecting joint of the building block connector. The annular protrusions are formed by two funnel-shaped convex rings fitting together, and their dimensions match the end dimensions of the funnel-shaped connecting hole. The building block connectors are generally cylindrical or arc-shaped. The cylindrical block connector 11 is cylindrical in shape, with connecting joints at both ends that can be inserted into the connecting hole, and the annular protrusion is located in the middle of the block connector. The arc-shaped block connector 12 is arc-shaped, with connecting joints at both ends that can be inserted into the connecting hole, and the block connector has two independent annular protrusions, each near the end of a connecting joint. Figure 3 The diagram shows several possible examples of modular connection structures.

[0023] Compared with existing technologies, the beneficial effects of this technical solution are as follows:

[0024] 1. Because the cross-sectional dimensions of the connector and the connecting hole are matched, the end of the connecting hole located on the outer surface of the block is funnel-shaped, and the end of the connector is frustum-shaped. These two structures make the cross-sectional dimensions of the connecting hole end larger than the cross-sectional dimensions of the connector, making it easier for children to align and insert the connector into the end of the connecting hole during assembly, significantly increasing the success rate of assembly alignment.

[0025] 2、When the connecting hole is a through hole, a protrusion can be arranged in the middle of the inner wall of the through hole, the outer diameter of the connecting joint is larger than the inner diameter of the protrusion of the inner wall of the connecting piece, which can limit the depth of the connecting joint inserted into the connecting hole. At the same time, the connecting joint is provided with a ring-shaped protrusion matching the size of the end of the funnel-shaped connecting hole, which can also limit the depth of the connecting joint inserted into the connecting hole.

[0026] 3、When the connecting hole is a blind hole, it can also limit the depth of the connecting joint inserted into the connecting hole.

[0027] 4、When the building block connecting piece is in a cylindrical shape, the ring-shaped protrusion is arranged in the middle of the building block connecting piece. When the building block connecting piece is in an arc shape, the building block connecting piece has two independent ring-shaped protrusions, respectively close to the end of the two connecting joints. Each building block connecting piece can be connected to the connecting hole from at least two directions, achieving the effect of multi-directional splicing.
