[0001] This utility model relates to the field of early childhood education tools technology, specifically a detachable early childhood building construction teaching tool. Background Technology

[0002] In early childhood education, construction building aids play a vital role in promoting children's cognitive, hands-on, and spatial reasoning abilities. Currently, a wide variety of early childhood construction building aids are available on the market.

[0003] Many existing preschool building materials have relatively simple structures, mostly consisting of simple stacking of blocks. The connection methods are often fixed; for example, traditional blocks are simply stacked together by gravity, making them prone to collapse and unable to meet children's needs for building complex structures. In actual use, children often encounter problems such as weak connections between blocks and unsatisfactory building results. This not only reduces children's enthusiasm for building activities but also limits their exploration of various structural and spatial relationships during the building process. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a detachable teaching aid for children's building construction.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0026] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0027] Example

[0028] like Figure 1 As shown, a detachable preschool building construction tool mainly consists of several building blocks 1 forming a block strip. The building block 1 has a square structure, with strip-shaped locking blocks 2 and circular locking blocks 3 on any two opposite surfaces. The strip-shaped locking blocks 2 engage with a groove 11 on the building block 1 via a slider 24, with the slider 24 fitted onto a guide rod 12 within the groove 11, allowing the strip-shaped locking blocks 2 to slide on the building block 1. The circular locking blocks 3 are rotatably connected to the building block 1 via an upper annular rotating frame 34, enabling rotatable installation.

[0029] Figure 1 , Figure 2 These represent the two bar-shaped cards in their open and closed states, respectively.

[0030] When building with blocks, the pressing block 16 of the upper block 1, as the upper and lower blocks 1 are attached, comes into contact with the second contact surface 22 of the strip-shaped locking block 2 of the lower block 1 through the first contact surface 17. This compresses the strip-shaped locking block 2 of the lower block 1 towards the circular locking block 3 of the upper block 1, until the strip-shaped locking block 2 and the circular locking block 3 are locked together. In addition, the side of the strip-shaped locking block 2 facing away from the second contact surface 22 has an arc-shaped groove 21. During locking, the circular locking block 3 can gradually fit into the lower arc-shaped groove 21, so that the locking block 23 on the groove wall matches the locking groove 31 on the circumference of the circular locking block 3, achieving a locking state to ensure the stability of the structure after the blocks are assembled.

[0031] Two sets of strip-shaped blocks 2 are symmetrically arranged. The cooperation between the lower slider 24 and the guide rod 12 ensures the stability and smoothness of the strip-shaped blocks 2 during the sliding process.

[0032] like Figure 4 As shown, the circular locking block 3 has an annular groove 32 in the middle. The locking pin 33 on the inner wall of the annular groove 32 engages with the spiral guide groove 42 at the bottom of the push rod 4. The push rod 4 is set in the through groove 13 of the block 1. The limiting groove 43 on the push rod 4 engages with the limiting rod 19 in the through groove 13. A return spring 44 is provided between the limiting rod 19 and the limiting groove 43. A pressing plate 41 is provided on the top of the push rod 4. When it is necessary to disassemble the block, press down on the pressing plate 41, the push rod 4 moves downward, the locking pin 33 moves in the guide groove 42, so that the circular locking block 3 can rotate, thereby rotating the locking groove 31, which can push the locking block 23 out of the locking groove 31, thereby releasing the locking state with the strip locking block 2. When the pressing plate 41 is released, the push rod 4 returns to its original position under the action of the return spring 44.

[0033] The two sides of the snap-fit ​​block 23 are symmetrically inclined surfaces. When this inclined surface is in contact with the slot 31, it can be easily squeezed to the side by the rotation of the slot 31.

[0034] like Figure 3 As shown, the block 1 has a receiving groove 15 on one side with a circular locking block 3. The circular locking block 3 and the pressing block 16 are both located in the receiving groove 15. The receiving groove 15 can cover and store the overlapping parts when the blocks are assembled. This design is not only beautiful, but also protects the internal structure and prevents collision damage.

[0035] The four corners of the block 1 with the strip-shaped card block 2 are provided with right-angled auxiliary blocks 14. The rubber pressing blocks 18 at the corners of the receiving groove 15 abut against the sides of the auxiliary blocks 14 of the lower block 1 when the block 1 is assembled, which further enhances the stability of the block assembly structure and prevents the blocks from shifting during the assembly process.

[0036] like Figure 5 As shown, the building blocks 1, composed of several building blocks, can be combined into different building structures during the building process. By continuously combining the building blocks, various shapes of building structures can be built. This achieves the design goal of novel structure, convenient and firm connection, easy assembly and disassembly, and can meet the diverse building needs of children, providing them with a better building experience.

[0037] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
