Description

Technical Field

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

[0002] The most common design of existing toy building block structures is as follows: one building block has a protrusion, and another building block has a corresponding concave part. Various building block shapes can be assembled by fitting the protrusions and concave parts together. For example, CN213965164U discloses a novel interlocking building block component and structure, including several building block components of different shapes and sizes. These components include, but are not limited to, a first component, a second component, a third component, a fourth component, a sixth component, an eighth component, and a tenth component. The first component is an arc-shaped column with at least one partition inside. A first cross is located at each end of the first component. The second component is an arc-shaped racetrack that matches the side of the first component. Several protrusions are located on the side of the second component, and the partition is inserted between these protrusions. The third component is a cube-like structure with six sides. The sixth component has a second cross-shaped joint. One side of the sixth component has a first groove containing four first insertion slots. One side of the eighth component has four first insertion posts, and the other side of the eighth component has a second groove containing four second insertion slots. One side of the tenth component has four square insertion slots, and the other side of the tenth component has a cross-shaped groove. The first and second cross-shaped joints can be inserted into and matched with the cross-shaped grooves. The gaps between the four first insertion slots and the four second insertion slots are defined. The four first insertion posts are matched one-to-one with the four square insertion slots. However, this method of splicing grooves and protrusions is prone to separation, resulting in relatively poor stability. It cannot meet the requirements for shapes with high assembly requirements, such as arch bridges. Utility Model Content

[0003] The present invention aims to provide a building block assembly structure to solve the technical problems existing in the prior art.

[0004] The technical solution of this utility model is as follows:

[0005] A modular assembly structure includes a convex shell and a concave shell fixed to a housing, both of which are cylindrical. The outer wall of the convex shell has a locking groove, formed by raised steps on both sides and an abutment at the front end, with the raised steps protruding from the outer wall of the convex shell. The inner wall of the concave shell has a locking block corresponding to the locking groove, protruding from the inner wall of the concave shell. The locking block has a certain elastic deformation space in the radial direction of the concave shell. When two building blocks are assembled together using the convex and concave shells, the locking block engages within the locking groove, and the end of the locking block abuts against the abutment, preventing the locking block from axially disengaging from the locking groove, thereby achieving a stable assembly between the two building blocks.

[0009] The concave shell has an opening, and the snap-fit ​​block is located inside the opening. The end of the snap-fit ​​block that abuts against the abutting part is a free end, and the free end protrudes from the inner sidewall of the concave shell to achieve abutment and snap-fit ​​with the snap-fit ​​groove.

[0010] The side of the snap-fit ​​block opposite the snap-fit ​​groove is sloping, and the snap-fit ​​block has a wedge-shaped design that gets thicker and thicker from the fixed end to the free end.

[0011] The housing includes a first housing and a second housing, which are fixed together by fasteners.

[0036] Example 1

[0037] like Figures 1-4 As shown, a building block assembly structure includes:

[0038] (1) Housing: The housing is formed by fixing the first housing 101 and the second housing 102 together with the fastener 104. The housing is provided with a mounting window 103 and a mounting groove is provided around the mounting window 103. The fastener 104 can be fastened by screws or by fixing sleeve stamping fastening.

[0039] (2) Convex shell 202: The convex shell 202 is cylindrical; the outer wall of the convex shell 202 is provided with a snap-fit ​​groove 204, which is formed by the raised steps 205 on both sides and the abutment part 203 at the front end. The raised steps 205 protrude from the outer wall of the convex shell 202; the side of the raised steps 205 near the snap-fit ​​groove 204 is designed as a vertical surface, or the bottom of the side is designed as a vertical surface and the top is designed as an arc transition surface, so that the snap-fit ​​block 303 is not easy to detach from the snap-fit ​​groove 204; the side of the raised steps 205 away from the snap-fit ​​groove 204 is designed as an arc transition surface, so that when the snap-fit ​​block 303 is misaligned with the snap-fit ​​groove 204, rotating the block can make the snap-fit ​​block 303 easily pass over the raised steps 205 and snap into the snap-fit ​​groove 204.

[0040] (3) Concave shell 302: The concave shell 302 is also cylindrical and is adapted to the convex shell 202. The concave shell 302 is provided with an opening 304. The inner side wall of the concave shell 302 is provided with a snap-fit ​​block 303 corresponding to the snap-fit ​​groove 204. The snap-fit ​​block 303 is located in the opening 304. The end of the snap-fit ​​block 303 that abuts against the abutting part 203 is a free end, so that the snap-fit ​​block 303 has a certain elastic deformation space in the radial direction of the concave shell 302. The free end protrudes from the inner side wall of the concave shell 302. The side of the snap-fit ​​block 303 opposite to the snap-fit ​​groove 204 is sloping. The snap-fit ​​block 303 has a wedge-shaped design that gets thicker and thicker from the fixed end to the free end, so that the snap-fit ​​block 303 can easily pass over the abutting part 203 of the snap-fit ​​groove 204 and be snapped with the abutting part 203.

[0041] (4) First mounting plate 201 and second mounting plate 301: The first mounting plate 201 and the second mounting plate 301 are fixed to the convex shell 202 and the concave shell 302 respectively, and the first mounting plate 201 and the second mounting plate 301 are provided with positioning skirts. The first mounting plate 201 and the second mounting plate 301 are fixed to the mounting window 103 by the positioning skirts and the mounting groove.

[0042] When two building blocks are assembled together via the convex shell 202 and the concave shell 302, the locking block 303 engages within the locking groove 204, and the end of the locking block 303 abuts against the abutment part 203. The abutment part 203 prevents the locking block 303 from axially disengaging from the locking groove 204, thus achieving a stable assembly between the two building blocks. When it is necessary to disassemble the assembly, simply rotate the two building blocks slightly to unscrew the locking block 303 from the locking groove 204. The raised step 205 is designed to protrude from the outer wall of the convex shell 202 so that when the convex shell 202 and the concave shell 302 are assembled, the outer wall of the convex shell 202 and the inner wall of the concave shell 302 are not in a tightly fitted state, thus facilitating rotation and separation.
