Description

Technical Field

[0001] This utility model belongs to the field of building block structure technology, and more specifically relates to an elastic building block structure. Background Technology

[0002] Currently, all building blocks are designed to be interconnected. Most interconnected building blocks are made of hard plastic or wood, which allows the blocks to interlock and remain firmly connected until manually pulled apart. However, building blocks made of hard plastic or wood have hard edges and corners, which pose certain dangers to younger children when playing with them, such as accidentally stepping on them, twisting their ankles, falling, bumping into things, or being hit by falling blocks.

[0003] Therefore, some flexible building blocks have appeared on the market, which can effectively avoid the above-mentioned dangers. However, the elasticity makes it impossible for the concave and convex parts of the building blocks to fit together effectively, which affects the playability of building block assembly. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a flexible building block structure that reduces the danger during assembly and disassembly, and is easy to assemble.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an elastic building block structure, including an elastic shell, a cavity inside the elastic shell, at least one protrusion and at least one groove on the elastic shell, the protrusion being hollow inside, a slanted buckle being provided on the outer side of the end of the protrusion, a ventilation groove being provided on the slanted buckle extending from the top of the slanted buckle along the surface of the slanted buckle to the bottom of the slanted buckle, and the maximum diameter of the slanted buckle being larger than that of the groove.

[0006] Furthermore, the elastic shell includes a main body and a base plate, the protrusion is located on the main body, the groove is located on the base plate, the edge of the main body is provided with a mounting groove, and the base plate is provided with a mounting strip corresponding to the mounting groove, the mounting strip being bonded to the mounting groove.

[0007] Furthermore, the elastic outer shell has recessed support grooves on its four sides.

[0008] Furthermore, when there are multiple bumps and grooves, the number of bumps and grooves may be the same or different.

[0009] Furthermore, the cavity is filled with a filler material.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: the two elastic building blocks are connected by splicing the protrusions and grooves on them. The inclined fasteners on the protrusions ensure the stability after splicing and prevent the building blocks from separating. Furthermore, since the building blocks are elastic, the danger during splicing and disassembly is reduced. The air pressure difference inside and outside the groove during splicing or disassembly is balanced by the air grooves on the surface of the inclined fasteners, preventing the protrusions from being unable to be removed or squeezed in. At the same time, the gaps formed by the air grooves and the hollow protrusions allow the inclined fasteners to deform well during splicing or disassembly, thus facilitating splicing.

[0015] Reference Figure 1 and Figure 2 The present invention will be further described below.

[0016] A flexible building block structure includes an elastic outer shell 1, with a cavity 2 inside the elastic outer shell 1. The elastic outer shell 1 has at least one protrusion 3 and at least one groove 4. The protrusion 3 is hollow inside. A beveled fastener 5 is provided on the outer surface of the end of the protrusion 3. A venting groove 6 is provided on the beveled fastener 5, extending from its top end along its surface to its bottom end. The maximum diameter of the beveled fastener 5 is larger than that of the groove 4. Figure 1 and Figure 2 As shown, different building blocks have different shapes, and their surfaces are provided with different protrusions 3 and grooves 4. Two building blocks can be joined together by connecting the protrusions 3 and grooves 4. Due to its elasticity, the protrusions 3 and the angled interlocking blocks 5 can be well pressed into the cavity 2 from the grooves 4. During pressing, the air pressure difference inside and outside the cavity 2 can be maintained through the ventilation grooves 6, preventing the protrusions 3 from being unable to be removed or squeezed in. Figure 2 As shown, building blocks can have many different shapes, including cylindrical, spherical, triangular, and other geometric shapes not shown in the attached diagram. Figure 1 As shown, in this preferred embodiment, the elastic outer shell 1 includes a main body 8 and a base plate 9. The protrusion 3 is located on the main body 8, and the groove 4 is located on the base plate 9. The edge of the main body 8 is provided with a mounting groove 10, and the base plate 9 is provided with a mounting strip 11 corresponding to the mounting groove 10. The mounting strip 11 is bonded to the mounting groove 10. Specifically, separating the production of the main body 8 and the base plate 9 makes production more convenient, improves quality, and facilitates bonding with silicone during filling and splicing within the cavity 2. Figure 1 As shown, in this preferred embodiment, the elastic shell 1 has concave support grooves 7 on its four sides. These support grooves 7 increase the force driving the elastic shell 1 to undergo elastic deformation, making the elastic shell 1 less prone to deformation. In this preferred embodiment, when there are multiple protrusions 3 and grooves 4, the number of protrusions 3 and grooves 4 can be the same or different. For example, there may be three protrusions 3 and only one, two, three, or more grooves 4. Similarly, the number of grooves 4 can be determined accordingly. In this preferred embodiment, the cavity 2 can be filled with several elastic balls. The elastic balls can be solid or hollow, completely filling the cavity 2. Alternatively, smaller hard beads can be used. To facilitate the elastic deformation of the building blocks, a small portion of the cavity 2 needs to be left empty. Flexible materials such as sponge can also be used.

[0017] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
