Description

Technical Field

[0001] The present invention relates to the field of magic block board splicing, in particular to a single magic block board structure. Background Art

[0002] Magic blocks are generally made of plastic or wood, or metal. They can be used as children's educational toys and can be pieced together into many three-dimensional toys. At present, there are various magic block toys on the market. For example, Lego blocks are a kind of plastic building blocks invented by Olli Kirk Christiansen of Denmark. They have convex particles on one side and grooves on the other side for embedding the convex particles. There are more than 1,300 shapes, and each shape has 12 different colors, mainly red, yellow, blue, white and black. It relies on children's own brains and hands to piece together endless shapes, which makes people love it and is called "magic plastic building blocks". However, the shape of each Lego board is different. Therefore, there is very little research on the effective piecemeal connection between single magic blocks (that is, the shapes of each board are exactly the same). Single magic blocks have the characteristics of small number of molds (the structure of each board is exactly the same) and simple and easy piecemeal connection (few piecemeal directions).

[0003] At the same time, many people use it to piece together various furniture such as wardrobes, tables, beds, etc. Because the magic board can be reused, it can also be used as a recyclable express packaging box to place precious paintings, cigarettes, alcohol, and treasures.

[0004] For example, the Chinese utility patent, patent number 201320625214.9, is about a corrugated compressed cardboard that can be easily assembled and disassembled. If it is assembled into a table, although the protrusions on the buckles are used to limit the grooves in the card body for positioning, the force points of this splicing method are all at the buckles, which are actually unable to withstand large forces, and after splicing, there are gaps between each board.

[0005] Another example is the Chinese utility model patent with the patent number of 201720821508.7. The patent name is a single magic block board structure that is tightly connected using corner fasteners. This structure can completely seal the gaps and cracks between each board, but the actual object is easy to fall apart. For example, when assembled into a large cube, although there is friction between each board, the friction between the corner fasteners is limited. Because the function of the corner fastener is to seal the corners, due to its small size and small contact surface, the friction is small, and the actual object is very easy to fall apart.

[0006] For example, the Chinese utility patent, patent number 201220482335.8, patent name is sheet assembly component with symmetrically distributed slots; and the US patent, announcement number US2005287906 A1, patent name is multifunctional embedded template system, using buckle tongue to plug into the buckle tongue slot of another board, or buckle tongue to buckle tongue, and then for rigid sheets that cannot be bent, the connection structure can be placed on the outside, compared with general bendable sheets, which can be bent along the edge, and the interlaced structure is placed on the inside of the three-dimensional shape, but for magic block boards that are all made of wood or plastic, it is definitely impossible to bend. The connection structure is placed on the outside. On the one hand, the structural strength is low, and on the other hand, it is ugly and easy to hurt people. For materials that can be bent, the connection structure is placed on the inside of the sheet. On the one hand, it is assembled into a three-dimensional object that cannot be disassembled or is difficult to disassemble, because the force points for disassembly are all on the inside of the three-dimensional object. On the other hand, even if it is disassembled and reused, the repeated bending along the edge will easily break the bend.

[0007] There is another problem. In any of the above solutions, each board cannot be detachably connected to each other. Summary of the invention

[0008] The purpose of the present invention is to address the shortcomings of the prior art, at least to a certain extent, solve the technical problems in the related technology, and provide a single magic block board structure to achieve the purpose of improving the structural strength of the magic block boards after splicing and not easy to fall apart and high stability.

[0009] In order to solve the above technical problems, the technical solution of the present invention is: a single magic block board structure, including a plurality of magic block boards, one of the opposite sides of the magic block board is provided with a splicing foot, and the other opposite side is provided with a splicing foot corresponding to the above splicing foot, each magic block board is spliced ​​with another magic block board through the splicing foot staggered splicing, and also includes a plurality of live buckles, the live buckle includes a buckle body, one side or both sides of the buckle body are provided with a protrusion, and the buckle body is provided with a barb strip or the buckle body is provided with two barb strips arranged oppositely;

[0010] The magic block plate is provided with a hidden fastening structure for hiding the buckle and making the two magic blocks and the buckle mutually buckle, press and pull each other.

[0011] Furthermore, each magic block board is horizontally connected to another magic block board through the staggered pins, and the magic block board is provided with a first hidden fastening structure for hiding the buckle and making the two magic blocks and the buckle mutually buckle, squeeze and pull each other.

[0012] Furthermore, each magic block board is vertically connected to another magic block board through the staggered pins, and the magic block board is provided with a second hidden buckle structure for hiding the buckle and making the two magic blocks and the buckle mutually buckle, squeeze and pull each other.

[0013] Furthermore, the first hidden fastening structure includes a barb groove which is provided on one of the opposite sides of the magic block board and whose opening portion is adapted to the buckle body and adapted to the barb strip, and a groove which is provided on two opposite sides of the magic block board and corresponding to the staggered position of the magic block board and adapted to the protrusion.

[0014] Furthermore, the second hidden buckle structure includes a barb groove which is provided on one of the opposite sides of the magic block board and whose opening part is adapted to the buckle body and adapted to the barb strip, and a limit groove which is provided on two opposite sides of the magic block board and whose two feet are misaligned with the magic block board and adapted to the protrusion.

[0015] Furthermore, the movable buckle is provided with a limiting slider and a limiting sliding groove adapted to the limiting slider, and each movable buckle is slidably engaged with another movable buckle through the limiting slider and the limiting sliding groove.

[0017] Furthermore, one of the opposite sides of the magic block board is provided with two pins, and the other opposite side is provided with three pins corresponding to the two pins.

[0018] Furthermore, the magic block board is a square board, and the sum of the lengths of all the stitching feet on any one of the opposite sides of the magic block board plus the sum of the lengths of all the stitching feet on any one of the other opposite sides is equal to the length of the magic block board.

[0019] Furthermore, sealing blocks are provided at the four corners of the magic block plate.

[0020] The technical effects of the present invention are mainly reflected in the following aspects: 1: The design of the present invention increases the contact surface between each magic block board and the lock, thereby increasing the friction, the pulling force between each other and the extrusion force between each other, so that the assembled three-dimensional object is not easy to fall apart, and the structural strength is greater; 2: The lock and the two magic blocks are locked with each other, and the lock can hide the connection points of each magic block board (including vertical connection points, horizontal connection points, and stacked connection points) to prevent people from being stabbed, which is more beautiful and the assembled object has a higher flatness; 3: Each magic block board can be stacked and effectively fastened; 4: The present invention can be assembled into a table The invention can be used for chairs, benches, toys, cabinets, boxes, shelves, packaging boxes, decorations, and can be combined with lights to form decorations or background decorative walls, etc., and can be reused after disassembly; 5: The ingenuity of the present invention lies in: when connected horizontally, the structure of the snap button is adapted to the open part, the barb groove, and the groove; when connected vertically, the structure of the snap button is adapted to the open part, the barb groove, and the limit groove adapted to the snap button; when connected in a stacked manner, the limit slide groove of the snap button is adapted to the limit slide block of another snap button and the snap button is adapted to the open part and the barb groove.

[0048] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention so that the technical solution of the present invention is easier to understand and grasp, but should not be understood as a limitation to the present invention.

[0049] Example 1

[0050] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Fig.13 and Fig.14 As shown: a single magic block board structure, including multiple magic block boards 1, one of the opposite sides of the magic block board 1 is provided with two splicing feet 11, and the other opposite side is provided with three splicing feet 11 corresponding to the above two splicing feet 11, the magic block board 1 is a square board, the sum of the lengths of the two splicing feet 11 on any one side of one opposite side of the magic block board 1 plus the sum of the lengths of the three splicing feet 11 on any one side of the other opposite side is equal to the length of the magic block board 1, each magic block board 1 is spliced ​​with another magic block board 1 through the splicing feet 11, and also includes a plurality of buckles 2, the buckle 2 includes a buckle body 21, both sides of the buckle body 21 are provided with protrusions 22, the buckle body 21 is provided with two oppositely arranged barb strips 23, and the cross section of the barb strip 23 is "L" shaped;

[0051] The magic block plate 1 is provided with a hidden fastening structure for hiding the buckle 2 and making the two magic blocks 1 and the buckle 2 mutually buckle, press and pull each other.

[0052] like Figure 8 As shown: each magic block board 1 is horizontally connected to another magic block board 1 through the misaligned joint foot 11, and the magic block board 1 is provided with a first hidden fastening structure for hiding the buckle 2 and making the two magic blocks 1 and the buckle 2 mutually buckle, squeeze and pull each other, and the first hidden fastening structure includes an opening 12 provided on an opposite side of the magic block board 1 and adapted to the buckle body 21 and the barb groove 13 adapted to the barb strip 23, and a groove 14 provided on the other opposite side of the magic block board 1 and on the two joint feet 11 corresponding to the misalignment of the joint foot 11 and adapted to the protrusion 22.

[0053] In this embodiment, the opening portion 12 and the barb groove 13 are arranged on the middle pin 11 of the three pins 11 on the opposite side of the magic block board 1, and the groove 14 is arranged on the pin 11 with two pins 11 on the opposite side of the magic block board 1, so that the buckle body 21 is hidden between the two horizontally connected magic blocks 1, the barb strip 23 is slidably inserted into the barb groove 13, and the protrusion 22 is slidably inserted into the groove 14. Therefore, the shape of the buckle 2 is equivalent to the hollow space formed by the combination of the two grooves 14, the opening portion 12 and the barb groove 13 between the two magic blocks 1. Through the design of the buckle, the contact surface of each connecting member is increased, thereby increasing the friction of each connection when connected. , the effect of mutual interlocking, mutual squeezing and mutual pulling between the two magic blocks 1 and the live buckle 2 can be achieved. In the actual production process, the adaptation mentioned above can also be that the size of the live buckle 2 in one direction or multiple directions is slightly larger than the hollow space, and slightly larger by 0.01 mm-0.1 mm is optimal, or small convex points or small convex pieces 02 of 0.01 mm-0.1 mm are set on several faces or one face of the live block to increase the friction and increase the mutual squeezing force of each connecting part. After plugging, an effect similar to metal interference fit is achieved, which can maximize the effect of mutual interlocking, mutual squeezing and mutual pulling between the two magic blocks 1 and the live buckle 2.

[0054] like Fig. 9 , Fig.11 and Fig.12 As shown: each magic block board 1 is vertically connected to another magic block board 1 through the misaligned joint feet 11, and the magic block board 1 is provided with a second hidden buckle structure for hiding the buckle 2 and making the two magic blocks and the buckle 2 mutually buckle, squeeze and pull each other, and the second hidden buckle structure includes an open part 12 adapted to the buckle body 21 and the barb groove 13 adapted to the barb strip 23, which is arranged on the joint feet 11 on one opposite side of the magic block board 1 and is adapted to the barb groove 13 of the barb groove 23, and a limiting groove 15 is arranged on the other opposite side of the magic block board 1 and on the two joint feet 11 corresponding to the misalignment of the joint feet 11 and is adapted to the protrusion 22, and the front and back sides of the two joint feet corresponding to the misalignment of the joint feet 11 are provided with two limiting grooves 15.

[0055] In this embodiment, the opening portion 12 and the barb groove 13 are arranged on the middle pin 11 of the three pins 11 on the opposite side of the magic block board 1, and the limiting groove 15 is arranged on the pin 11 of the two pins 11 on the opposite side of the magic block board 1. The center line of the limiting groove 15 is vertical to the center line of the groove 14 in space. The purpose is to hide the buckle body 21 between the two pins 11 on the opposite side of the magic block board 1, so that the barb strip 23 is slidably inserted into the barb groove 13, and the protrusion 22 is slidably inserted into the limiting groove 15. When connecting, the buckle is inserted into the opening portion and the barb groove (such as Fig.11 As shown: a thick solid line-shaped slot is formed), and then another magic block board ( Fig.12The projection of the thick solid line in the middle) is vertically inserted into the above-mentioned slot, which will achieve the effect of mutual engagement, mutual extrusion and mutual pulling between the two magic blocks 1 and the buckle 2. The order of the above-mentioned assembly can be changed. In the actual production process, the size of the buckle 2 in one direction or multiple directions is slightly larger than the limit groove, the opening part and the barb groove. It is best to be slightly larger by 0.01 mm-0.1 mm. After plugging, an effect similar to metal interference fit is achieved, which can maximize the effect of mutual engagement, mutual extrusion and mutual pulling between the two magic blocks 1 and the buckle 2. When disassembling, squeeze the buckle hard to make it fall off, so as to achieve the purpose of convenient disassembly.

[0056] like Figure 7a , Figure 7b , Figure 7c and Fig.10 As shown: the movable buckle 2 is provided with a limit slider 27 and a limit slot 28 adapted to the limit slider 27, each movable buckle 2 is slidably engaged with another movable buckle 2 through the limit slider 27 and the limit slot 28, the limit slider 27 is in a "T" shape, each magic block plate 1 is superimposed and connected with another magic block plate 1, each movable buckle 2 is engaged with another movable buckle 2, and the movable buckle 2 is engaged with the open portion 12 and the barb groove 13 of the magic block plate 1. Through the above design, the movable buckle 2 is engaged with the middle of the opposite side of the magic block plate 1 with three pins 11, and each movable buckle 2 is engaged with the movable buckle 2, which plays a role in tightening the connection during the actual stacking process. When connecting, the magic block plates are stacked in order to form a strip-shaped barb groove, and then the movable buckles are mutually clamped and stacked into a straight line, and then a row of movable buckles that are mutually clamped and stacked into a straight line are clamped into the above-mentioned strip-shaped barb groove.

[0057] like Figure 8 and Fig. 9 As shown: the magic block board 1 is a square board, the sum of the lengths of the two pins 11 on any one of the opposite sides of the magic block board 1 plus the sum of the lengths of the three pins 11 on any one of the other opposite sides is equal to the length of the magic block board 1. Through the above design, the magic block board 1 is seamlessly connected with the magic block board.

[0058] like Figure 8 and Fig. 9 As shown: sealing blocks 01 are provided at the four corners of the magic block board 1, and the function of the sealing blocks 01 is to achieve seamless connection of the corners between the magic block boards 1 and the magic block boards 1.
