2. Description of the Background Art Generally, a conventional assembling type block toy set is formed of cubic unit blocks each having a corresponding matching surface with a force fit convex-concave structure in a male and female structure corresponding to opposite both sides.
Therefore, the unit blocks are matched with their matching sides and are pressurized in an engaging direction, so that a matching side concave-convex structure of one side unit block is force-fit to a matching side concave-convex
structure of another unit block. Therefore, a plurality of unit blocks are sequentially assembled in the above manner for thereby forming a certain shape like a robot, etc.
However, in the conventional assembling type block toy set, since the matching side convex-concave structure of each unit block is designed to be force- fit by a certain pressurizing force so that the unit blocks are assembled and then are not easily disassembled, a large pressurizing force is required for assembling the unit blocks. Therefore, in the conventional art, it is not easy to assemble and disassemble. Therefore, it is very difficult for children or baby who have a small grasping force to assemble and disassemble the unit blocks, so that it is impossible to. make a certain shape using the unit blocks.
SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide an assembling type block toy which overcomes the problems encountered in the conventional art.
It is another object of the present invention to provide an assembling type block toy which is capable of easily assembling and disassembling unit blocks in such a manner that each unit block is matched and engaged based on a convex-
concave structure of a simple insertion structure and a magnetic force of a magnet, and it is possible to make various shapes by providing a block wheel which may express a rotating member like a wheel except for a simple polygonal unit block and a block link which may express a joint or link.
To achieve the above objects, there is provided an assembling type block toy which includes a plurality of unit blocks which each have a concave-convex structure corresponding to each other and a matching side with a magnet of an opposite polarity and which is assembled and disassembled based on the concave-convex structure and a magnetic force of an opposite polarity magnet in such a manner that the corresponding matching sides are matched one another, a plurality of block links which are implemented in such a manner that two link blocks having the matching sides with a concave-convex structure and magnet corresponding to each matching side of the unit block at a front end are relatively rotatable to each other, and a block wheel which includes an engaging member having a matching side with a concave-convex structure and magnet corresponding to the matching side of each block in one side, and a rotating member which is engaged to a surrounding portion of the engaging member for thereby being rotatable along a circumference of the engaging member.
At this time, in a state that each magnet is mounted in a mounting groove
formed in each matching side, the magnet is force-fit in the mounting groove by a cap.
In a preferred embodiment of the present invention, the unit block is hexahedron, and each unit block includes a matching side corresponding to at least two sides opposite to each other.
In addition, the horizontal and vertical sizes and height of each unit block have a fixed number of magnification, and the unit blocks are formed of the unit blocks of a plurality of groups in which at least one of the horizontal and vertical sizes and height is increased at a fixed number magnification by the unit of group.
In addition, at least one link block of the block link is engaged to another link block to be rotatable with respect to a center shaft of the same.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The construction and operation of an assembling type block toy according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings.
As shown in Figures 1 and 2, the assembling type block toy according to an embodiment of the present invention includes a cubic unit block 1 which is used for forming a basic structure, a block wheel 2 which is adapted to form a certain rotating member like a wheel, etc. and a block link 3 which is adapted to express a joint or link of a robot.
At this time, the unit block 1 is a basic element of an assembling type block toy according to the present invention and is formed in a cubic shape as shown in Figure 3. The length, namely, horizontal size, vertical size and height of the same has a fixed number magnification to each other.
The unit block 1 is provided in multiple groups each formed in a few number or tens number which has the same horizontal and vertical sizes and height. As shown in Figures 3 and 6, the unit blocks have the fixed number
magnification in at least one of their horizontal and vertical sizes and heights.
In each unit block 1, the matching sides 1a and 1b are installed in such a manner that the upper and lower sides or left and right sides are formed in pair and are matched with the corresponding matching sides of another unit block based on at least two corresponding structures.
The matching sides 1a and 1b which are formed in pair have a convex- concave structure which is a corresponding shape. A magnet 13 is embedded in the interior of each matching side to have the opposite polarity. In the case of the assembling type block toy according to the present invention, as shown in Figures 4A and 4B, the magnets 13 are installed in the mounting grooves 10 and 11 formed in. each matching side 1a and 1b, and the magnets 13 are contacted with the matching sides 1a and 1b by a cap 12 which is force-fit to the mounting grooves 10 and 11.
The unit blocks 1 are matched with their corresponding matching sides 1 a and 1 b and are assembled in a convex-concave structure of the matching sides 1a and 1b and by a magnetic force of each magnet 13 as shown in figure 4B for thereby forming a certain structure as shown in Figures 1 and 2.
In the assembling type block toy according to the present invention, the sizes and shapes of the unit blocks 1 may be cuboid as shown in Figure 3 or cubic
