Description

A new type of splicing building blocks Technical Field

[0001] The present invention relates to the technical field of toys, in particular to a novel splicing building block. Background Art

[0002] Building blocks are typically cubic wooden or plastic toys that can be arranged in various ways for various building activities. They come in a variety of styles, can develop children's intelligence, and can be assembled into houses, for example. However, existing building blocks are typically rigid and inelastic, typically joined by inserting protrusions into grooves. This results in high production requirements and requires strict control over the dimensions of the protrusions and grooves. If the protrusions are too large, they will not fit into the grooves. If the protrusions are too small, the connection will be loose and unstable, making it difficult to meet practical usage requirements.

[0003] Summary of the Invention

[0004] The object of the present invention is to provide a new type of splicing building blocks, in which the outer diameter of the frustum of the new type of splicing building blocks gradually increases from top to bottom. When the building blocks are spliced, the frustum of the lower building block is tightly embedded in the gap between the four cylinders of the upper building block from bottom to top and is tightly clamped by the four cylinders. Moreover, since the building block base, frustum and cylinders are all made of a compressible and resilient soft elastic body such as EVA, the size requirements are relatively low, the connection is tight, it is not easy to loosen, and the stability is good.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] A novel splicing building block comprises a building block base, at least one frustum and at least four cylinders; the frustum is fixed to the upper end of the building block base, and the outer diameter of the frustum gradually increases from top to bottom; the rectangular array of cylinders is fixed to the lower end of the building block base; the building block base, frustum and cylinders are all made of soft elastic bodies, and the frustum of the lower layer of building blocks is tightly embedded in the gap between the four cylinders of the upper layer of building blocks from bottom to top; the frustum and cylinders are interference fit, and the building blocks of adjacent layers are spliced ​​together through the frustum and cylinders.

[0007] Furthermore, a tapered hole is provided in the middle of the cone; the upper opening of the tapered hole is larger than the lower opening of the tapered hole.

[0008] Furthermore, the upper end of the cylinder and the corresponding building block base are hollowed out to form a pit.

[0009] Furthermore, a frame is fixed to the outer edge of the upper end of the building block base; the upper end of the frame abuts against the lower end surface of the upper building block base.

[0010] Furthermore, a reinforcing rib is fixed on the upper end of the building block base; the reinforcing rib is located in the gap between the upper cylinders, one end of the reinforcing rib is fixedly connected to the outer wall of the truncated cone, and the other end of the reinforcing rib is fixedly connected to the adjacent outer wall of the truncated cone or the inner wall of the frame.

[0011] Furthermore, an edge is fixed on the inner wall of the upper end of the frame, and the outer wall of the upper cylinder is squeezed by the edge.

[0012] Furthermore, the building block base, frustum, cylinder, frame, reinforcement ribs and edges are an integrally formed structure.

[0013] Furthermore, the materials of the building block base, frustum, cylinder, frame, reinforcement ribs and edges are all EVA.

[0014] Furthermore, there are multiple frustums, which are arranged in a rectangular array.

[0015] After adopting the above technical solution, the present invention has the following beneficial effects:

[0016] 1. The present invention provides a novel splicing building block, wherein the outer diameter of the frustum gradually increases from top to bottom. When the building blocks are spliced ​​together, the frustum of the lower building block is tightly embedded in the gap between the four cylinders of the upper building block from bottom to top and is tightly clamped by the four cylinders. Moreover, since the building block base, frustum and cylinders are all made of a compressible and resilient soft elastic body such as EVA, the size requirement is relatively low, the connection is tight, it is not easy to loosen, and the stability is good.

[0017] 2. The present invention provides a novel splicing building block, in which a tapered hole is provided in the middle of the truncated cone, so that the truncated cone can be deformed inward when squeezed by a cylinder. The upper end of the cylinder and the corresponding building block base are hollowed out to form a pit, so that the cylinder can be deformed inward when squeezed by the truncated cone. The tapered hole provided in the middle of the truncated cone can make the wall thickness of the truncated cone thinner at the top and thicker at the bottom, which not only promotes the installation of the truncated cones and cylinders of adjacent layers together, but also improves the tightness of the installation of the truncated cones and cylinders of adjacent layers, and has a good use effect.

[0018] 3. The present invention provides a new type of splicing building block. The upper end of the building block base is fixed with a frame and reinforcing ribs, which can effectively limit the lateral deviation of the truncated table and improve the stability of the building block splicing.

[0019] 4. The present invention provides a new type of splicing building block, wherein the number of frustums is multiple, and the multiple frustums are arranged in a rectangular array, which can increase the splicing sites of adjacent layers of building blocks. BRIEF DESCRIPTION OF THE DRAWINGS
