Description

Technical Field

[0001] The invention relates to a building block combination toy with built-in connecting columns, and relates to the field of building blocks. Background Art

[0002] Building blocks are a common educational toy. They use various shapes as basic elements, each with its own clever logical relationship. These elements can be combined in unique ways to create new shapes. By combining different building blocks, children's imagination, creativity, hands-on skills, coordination, calculation, and spatial thinking abilities can be developed.

[0003] The existing building blocks are mostly built directly by stacking building blocks, or by connecting connecting blocks and connecting slots on the building blocks. The directly stacked traditional building blocks are convenient to build but lack stability and are prone to collapse. The plug-in building blocks can build more different shapes by connecting the connecting blocks and connecting slots, and the connection stability is high. However, in order to achieve a better building effect, the traditional plug-in building blocks need to be provided with different numbers of connecting posts on the building blocks to match the connecting slots, so as to realize the connection of different positions of the building blocks and extend the shape. However, the connecting parts of the existing building blocks are mostly extended structures on the outer shell, and most of them are hollow structures, which are easily damaged when a collision occurs. In addition, the building blocks with connecting blocks lack connecting slots and can only be used as specific connecting parts. When building different shapes, they are limited by the number of building block types. When there are no building blocks with connecting blocks or connecting slots, some shapes cannot be built or the shapes that fully meet the requirements cannot be built. Summary of the Invention

DETAILED DESCRIPTION

[0027] See Figures 1-11As shown, the technical solution adopted in this specific embodiment is: it includes a first building block 1, a second building block 2, and a third building block 3. The first building block 1 is provided with a movable through groove 1-1, and the movable through groove 1-1 is provided with a movable connecting column 5. The three first building blocks 1 are connected in parallel, the middle first building block 1 is connected to the first building blocks 1 on both sides through the movable connecting column 5, the bottoms of the first building blocks 1 on the left and right sides are connected to the second building blocks 2, the side of the first building block 1 on the left is also connected to a second building block 2, the top of the first building block 1 on the right is connected to the third building block 3, the third building block 3 is connected to the fourth first building block 1, and the fourth first building block 1 is provided with a fourth building block 4. In this embodiment, only one combination connection method is listed. All first building blocks 1 are cubes. Four movable connecting columns 5 are set in the first building blocks 1. They can be set to other shapes as needed. Among them, the movable connecting column 5 of the middle first building block 1 is placed horizontally, and the movable connecting columns 5 of the first building blocks 1 on the left and right sides are placed vertically to the movable connecting columns 5 of the middle first building block 1. The two movable connecting columns 5 in the diagonal position of the movable connecting columns 5 of the middle first building block 1 are pushed out in opposite directions respectively and connected to the first building blocks 1 on the left and right sides. The movable connecting columns 5 can be in two directions The four movable connecting columns 5 can be used in a variety of ways. When one connecting column is pushed out for use, the building blocks can be rotated and connected. The two connecting columns on the same side can be pushed out and connected to another building block without displacement. The two connecting columns opposite to each other can be pushed out to achieve complete alignment and connection of the two building blocks. The use of different connecting columns can produce different effects, and different shapes can be built, bringing higher building freedom. The built-in connecting columns will not cause any obstacles when not in use, and any shape can be built with only one building block, which can better give play to children's imagination and creativity.

[0028] Furthermore, the movable connecting column 5 comprises a square connecting column 5-1 and cylindrical connecting ends 5-2. The outer diameter of the cylindrical connecting ends 5-2 is equal to the side length of the square connecting column 5-1, and the cylindrical connecting ends 5-2 are arranged at both ends of the square connecting column 5-1. The cylindrical connecting ends 5-2 are used to connect and fix the building blocks together, and the square connecting column 5-1 can limit the movable connecting column 5 to prevent it from rotating during use.

[0029] Furthermore, a limiting ball spring 7 is provided on the square connecting column 5-1, and there are four limiting ball springs 7 in total, two of which are symmetrically arranged on the square connecting column 5-1 in a group, and a magnet 6 is provided on the cylindrical connecting end 5-2. The movable through groove 1-1 is a square hole through groove, and its shape and size match the square connecting column 5-1. The first positioning hole 1-4, the second positioning hole 1-5, the third positioning hole 1-6, the fourth positioning hole 1-7, the fifth positioning hole 1-8, and the sixth positioning hole 1-9 are provided on both sides of the inner wall of the movable through groove 1-1. The above-mentioned positioning holes match the limiting ball spring 7, and the spacing between the first positioning hole 1-4 and the second positioning hole 1-5 is equal to the spacing between the two limiting ball springs 7, the spacing between the third positioning hole 1-6 and the fourth positioning hole 1-7 is equal to the spacing between the two limiting ball springs 7, and the spacing between the fifth positioning hole 1-8 and the sixth positioning hole 1-9 is equal to the spacing between the two limiting ball springs 7. The cooperation of multiple positioning holes and the limiting ball spring 7 realizes the position fixing of the movable connecting column 5 in the building block body and the position fixing after being pushed out for use. The first positioning hole 1-4 and the second positioning hole 1-5 are used for position fixing when not in use, the third positioning hole 1-6 and the fourth positioning hole 1-7 are used for position fixing after one side is pushed out, and the fifth positioning hole 1-8 and the sixth positioning hole 1-9 are used for position fixing after the other side is pushed out. The movable through groove 1-1 is a square hole through groove, and its shape and size match the square connecting column 5-1, which can effectively prevent the rotation of the movable connecting column 5 and cause the misalignment of the limiting ball spring 7 and the positioning hole, thereby ensuring the positioning effect.

[0030] Furthermore, the first building block 1 is provided with detachable covers 1-10 at both ends. The covers 1-10 are located in the travel direction of the movable connecting column 5. The covers 1-10 are provided with connection limit holes 1-3, which match the cylindrical connecting end 5-2. The four sides of the first building block 1 are provided with connection grooves 1-2, which match the cylindrical connecting end 5-2. The covers 1-10 are snap-fitted to the first building block 1. The covers 1-10 are provided with connection limit holes 1-3 for limiting the movable connecting column 5. The shape of the connection limit holes 1-3 matches the cylindrical connecting end 5-2. When the movable connecting column 5 is over-extended, the square connecting column 5-1 will be limited by the connection limit holes 1-3, making it difficult for the movable connecting column 5 to be pushed out. When the building block needs to be extended and shaped, the covers 1-10 can be removed and the movable connecting column 5 can be taken out to achieve extended connection of the building block, making the shape more varied.

[0031] Furthermore, the bottom of the connecting groove 1-2 is also provided with a magnet 6. The connecting groove 1-2 is also provided with a magnet 6 and the magnet 6 on the movable connecting column 5 is attracted to each other to strengthen the connection between the building blocks and increase the stability of the shape.

[0032] Furthermore, the second building block 2 includes a first cone 2-1 and a second cone 2-2. A connector 2-1-1 is provided on the top of the first cone 2-1, and the connector 2-1-1 matches the connecting groove 1-2. The lower parts of the first cone 2-1 and the second cone 2-2 have the same structure. The lower part of the first cone 2-1 is provided with a tightening connector 2-1-2, and the tightening connector 2-1-2 is composed of a number of arc-shaped plates 2-1-3. A connecting cavity 2-2-1 is provided on the upper part of the second cone 2-2. The inner diameter of the opening of the connecting cavity 2-2-1 matches the outer diameter of the connecting head 2-1-1. The shape and size of the connecting cavity 2-2-1 match the tightening connector 2-1-2. An anti-slip strip 2-2-2 is provided on the inner wall of the connecting cavity 2-2-1. The second building block 2 is used as a shape-changing modeling piece, which consists of a first cone 2-1 and a second cone 2-2. The first cone 2-1 is connected to the connecting cavity 2-2-1 on the second cone 2-2 through a tightening connector 2-1-2. When the tightening connector 2-1-2 is inserted into the connecting cavity 2-2-1, the arc plate 2-1-3 will be tightened first. After being inserted into the connecting cavity 2-2-1, the arc plate 2-1-3 will relax and connect with the anti-slip strip 2-2-2, so that the second cone 2-2 can be rotated and positioned on the first cone 2-1 to form various curved or straight shapes.

[0033] Furthermore, the third building block 3 includes a first connecting post 3-1 and a second connecting post 3-2. The outer diameters of the first connecting post 3-1 and the second connecting post 3-2 match the inner diameter of the connecting slot 1-2. The first connecting post 3-1 and the second connecting post 3-2 are each provided with a connecting plate 3-1-1. The connecting plate 3-1-1 of the first connecting post 3-1 is provided with a connecting slot 3-1-2. The connecting plate 3-1-1 of the second connecting post 3-2 is provided with a rotating connecting post 3-2-1, which matches the connecting slot 3-1-2. The third building block 3 functions as a bending connector, and can be bent at different angles by connecting the rotating connecting post 3-2-1 with the connecting slot 3-1-2. At the same time, the outer diameters of the first connecting post 3-1 and the second connecting post 3-2 match the inner diameter of the connecting slot 1-2, making it easier to connect to the building block. The edges of the third building block 3 are provided with curved corners to reduce the risk of injury to children.

[0034] Working principle of the present invention: In this embodiment, only one combination connection method is listed. All the first building blocks 1 are cubes. Four movable connecting columns 5 are set in the first building block 1, which can be set to other shapes as needed. Among them, the movable connecting column 5 of the middle first building block 1 is placed horizontally, and the movable connecting columns 5 of the first building blocks 1 on the left and right sides are placed vertically to the movable connecting columns 5 of the middle first building block 1. The two movable connecting columns 5 in the diagonal position of the movable connecting columns 5 of the middle first building block 1 are pushed out in opposite directions respectively and connected with the connecting grooves 1-2 on the first building blocks 1 on the left and right sides. When the two movable connecting columns 5 on the right side are pushed out to the third positioning hole 1-6 position, the upper limiting ball spring 7 is stuck in the third positioning hole 1-6, the lower limiting ball spring 7 is stuck in the fourth positioning hole 1-7, and the two movable connecting columns 5 on the left side are pushed out to the sixth positioning hole 1-9 When the movable connecting column 5 is in the unlocked position, the upper limiting ball spring 7 is inserted into the sixth positioning hole 1-9, and the lower limiting ball spring 7 is inserted into the fifth positioning hole 1-8. When the movable connecting column 5 is not pushed, the upper and lower limiting ball springs 7 are inserted into the first positioning hole 1-4 and the second positioning hole 1-5 to fix the movable connecting column 5.
