Title: Building block

Description:
TECHNICAL FIELD 
     The present disclosure relates to a field of toy technology, and in particular to a building block. 
     BACKGROUND 
     Building blocks are usually cubic toys made of wood or plastic. Generally, decorative letters or pictures are coated on surface of each of the building blocks. Children are able to arrange or structure the building blocks into different styles. For example, the children are able to structure the building blocks into different houses, animals, etc. Structuring the building blocks can develop children&#39;s intelligence. 
     Conventional building blocks only comprise splicing structures arranged on two ends of each of the building blocks. An overall structural strength of the conventional building blocks is fragile, so the conventional building blocks are easy to break, have a short service life, are difficult to structure into a stable polygon structure, and unable to meet requirements of building blocks for an unmanned aerial vehicle (UAV) obstacle. Therefore, it is necessary to raise a solution to solve above problems. 
     SUMMARY 
     In view of defects in the prior art, the present disclosure provides a building block, which effectively solves problems that the conventional building blocks have structural strength, are easy to break, have short service life, and difficult to structure into a stable polygon structure. 
     In order to realize above purposes, the present disclosure provides a building block. The building block comprises a block body. The block body is of an integrated structure. The block body comprises a main body, first splicing portions, second splicing portions, a first raised portion, and two second raised portions. The main body is elongated. The main body horizontally extends from left to right. The first splicing portions horizontally extend outwards from one end of the main body. The second splicing portions obliquely extend upwards from a middle position of an upper surface of the main body. The first raised portion extends upwards from a right end of the main body. An outer side surface of the first raised portion is an inclined surface. The outer side surface of the first raised portion recesses to form first splicing grooves. The first splicing grooves are configured to tightly dock with and fix with first splicing portions or second splicing portions of another building block. The two second raised portions are arranged on the upper surface of the main body. An upper surface of each of the second raised portions is an inclined surface. The upper surface of each of the second raised portions recesses to form second splicing grooves configured to dock with and fix with the first splicing portions of another building block.

     DETAILED DESCRIPTION 
     Please refer to  FIGS.  1 - 4   , which show a specific structure of a building block according to one optional embodiment of the present disclosure. The building block comprises a block body  10 . 
     The block body  10  is of an integrated structure. The block body  10  comprises a main body  11 , first splicing portions  12 , second splicing portions  13 , a first raised portion  14 , and two second raised portions  15 . In the embodiment, the block body  10  is made of plastic, which is simple and easy to make with low cost. 
     The main body  11  is elongated. The main body  11  horizontally extends from left to right. First hollow grooves  101  run through the block body  10  from an upper surface of the main body  11  to a lower surface of the main body  11 . The first hollow grooves  101  have different shapes and sizes, which reduces the material used, reduces weight, and ensures a structural strength, while being aesthetically pleasing and durable. 
     The first splicing portions  12  horizontally extend outwards from a left end of the main body  11 . In the embodiment, two first splicing portions are provided. The two first splicing portions  11  are arranged in a row from front to back of the main body  11 . Each of the first splicing portions  12  is a square block structure. Further, a lower surface of each of the first splicing portions  12  recesses to form a second hollow groove  102 . By such arrangements, a weight of the building block is reduced by using less material on a premise of ensuring a structural strength of the building block. 
     The second splicing portions  13  obliquely extend upwards from a middle position of an upper surface of the main body  11 . In the embodiment, two second splicing portions  13  are provided. The two second splicing portions  13  are arranged in a row from left to right of the main body  11 . Each of the second splicing portions  13  is a right-angle trapezoidal block structure. A third hollow groove  103  is provided on each of the second splicing portions  13 . Each third hollow groove  103  is defined on a backside of each of the second splicing portions  13 . By such arrangements, the weight of the building block is reduced by using less material on the premise of ensuring the structural strength of the building block. 
     The first raised portion  14  extends upward from a right end of the main body. An outer side surface of the first raised portion  14  is an inclined surface. The outer side surface of the first raised portion  14  recesses to form first splicing grooves  104 . The first splicing grooves  104  are configured to tightly dock with and fix with first splicing portions or second splicing portions of another building block. In the embodiment, two first splicing grooves  104  are provided. The two first splicing grooves  104  are arranged in a row from front to back of the main body. The two first splicing grooves  104  run through the first raised portion. 
     The two second raised portions  15  are arranged on the upper surface of the main body  11 . An upper surface of each of the second raised portions  15  is an inclined surface. The upper surface of each of the second raised portions recesses to form second splicing grooves  105  configured to dock with and fix with the first splicing portions of another building block. In the embodiment, two second splicing grooves  105  are provided. The two second splicing grooves  105  are arranged in a row from front to back of the main body. 
     When in use, a plurality of building blocks of the present disclosure are provided. The first splicing portions of one of the plurality of building blocks are docked with and fixed with the first splicing grooves of another building block of the plurality of building blocks. The plurality of building blocks are connected in this way to form a polygonal structure. As shown in  FIG.  4   , the plurality of building blocks are built into an octagonal structure. It is understood that a hexagonal structure, a heptagonal structure, a nine-sided structure, a decagonal structure, an eleven-sided structure and a dodecagonal structure, etc., are built by different numbers of the building blocks, which are not limited thereto. A user can also take four building blocks of the present disclosure and build the four building block into an inverted T-shaped bracket to support the polygonal structure. 
     By arrangements of the first splicing portions, the second splicing portions, the first raised portion, and the two second raised portions, an overall structural strength of the building block of the present disclosure is effective improved; so the building block is not easy to break, service life of the building block is greatly increased, and the plurality of the building blocks of the present disclosure are capable of building into the stable polygon structure, which meets requirements of building blocks for an unmanned aerial vehicle (UAV) obstacle. With a premise of ensuring fun, a structure of the building block is reinforced, so that the building block is able to be used for a long time.
