[Prior Art] A table is a must-have for living and working, and can be found in a home or office or in general public places. However, the conventional table is assembled on a tripod, which is composed of a table top, and the shape of the table top is ιυ, which cannot be changed. Some tables can be rounded by the rounded edges, such as the table used in the restaurant. However, the rounded edge under the fold will occupy the space for the legs after the user sits down, and sometimes hinder the movement of the kick legs. 'It is not convenient to use, and it needs to be improved. [New content] In view of the problems of the prior art, the present invention provides a flip type circular square table, which comprises: a tripod having at least four vertical legs, so that a middle connecting portion stands smoothly; a square substrate, connected Above the connecting portion, a triangular groove is formed from the four edges to the center thereof; the four hinges each have a fixing piece and a rotating base M427853 which is relatively pivotable, and the fixing piece is fixedly connected to Below the four edges of the square substrate; four triangular plates are received in each of the triangular grooves of the square substrate and are fixedly connected to the rotating piece of the hinge above the bottom edge; and four sector plates are respectively fixedly connected to the hinge plate Above each of the four triangular plates, and each arc edge protrudes from the bottom edge of the fixed connection; the four sector plates form a circular table top; but each of the triangular plates can be connected to the hinge pivot of the rotating piece Flip 180 degrees to the same level as the square substrate, so that the four-piece three-check and the slab-axis enlarged square table, and the four-sector slabs are folded over the triangular plate and the square Shape under the substrate side. The rotary round square table provided by the present invention can convert the round table into a square table with an increased area, which can be changed according to the needs of the use site, and is convenient to use. In particular, after the round table is deformed into a square table, the sector plate is folded under the square table formed by the triangular plate and the square substrate, and the space for the reduction of the person's money is placed. & The present invention provides a _ rounded square table, wherein (4) the center of the connecting portion is provided with a sleeve, and the bottom surface of the square substrate is provided with a convex shaft at the center downward, and the protruding shaft extends into the sleeve to make the table top Rotate relative to the stand. The flip-type circular square table provided by the present invention, wherein the surface of the triangular plate is coated with the same color as the surface of the square substrate, and the fan-shaped plate is another color, so that the round table is turned into a square table, and a tone conversion effect is produced. The following description of the structure of the present invention will be described in detail with reference to the embodiments shown in the drawings. [Embodiment] Please refer to the first to third figures. The present invention provides a flip type 100' mainly consists of - a tripod ^ a square substrate ^ four money keys ' 2, four triangular plates 13, four pieces The sector plate 14 is formed. The stand 10 of the present invention has four vertical legs 10 1 so that the intermediate-distal portion 10 2 stands smoothly. The center of the connecting portion 1 〇 2 is provided with a sleeve. The top ends of the four straight legs 1〇1 are respectively provided with a horizontal rod i 〇 3 to the connecting portion 10 2 . Four horizontal rods 1G 3 are provided between two adjacent two horizontal rods 1 〇 3 - connecting reinforcing ribs 104, and the two connecting reinforcing ribs 1 〇 4 shown in the first figure are oppositely disposed. The square substrate 11 is connected above the connecting portion 1〇2, and is formed with a triangular groove 11 1 from its four edges toward the T center. The center of the bottom surface of the square substrate 11 is downwardly η and has a convex axis 112' which projects into the sleeve so that the table top can rotate relative to the stand 10. The four hinges 12 each have a fixing piece 121 and a rotating piece 123 rotatable relative to a pivot 12 2 which is fixedly coupled below the four edges of the square substrate 11. The four triangular plates 13 are housed in each of the triangular grooves 11 1 ' of the square substrate 11 and are fixedly connected to the rotating piece 1 2 3 of the money chain 12 above the bottom side 131. The i% connection state of the chain 1 2 and the triangular plate 13 and the square substrate 1 1 can be seen in the sixth figure. Four sector plates 14 are fixedly coupled to each of the four triangular plates 13 and the arc edges 141 of each of the four sector plates 14 protrude from the bottom edge 131 of the fixedly connected gusset plate 13. Referring to the second and third figures, the four sector segments 14 of the present invention form a circular table top. Further, as shown in the fourth figure, the triangular plate 3 can be inverted with respect to the hinge 12 pivot 12 2 of the connecting rotary cutter 2, as indicated by the arrow in the figure, and the triangular plate 13 can be flipped over the 18G-degree square substrate 1 1 The same-horizontal height, as shown in the fifth figure, does not form the four-sided gusset 13 and the square substrate 11 - the square table top of the enlarged area _ the sector sector plate i 4 is stacked on the triangular plate i 3 and the square substrate 1 Below the square table. After the three-touch i 3 turn, the connection state of the shop 2 to the triangular plate 13 and the square substrate 11 can be seen in the seventh figure. From the above description, we can see that the round table i Q 提供 provided by this new bribe can change the round table __ the enlarged square table, and the financial system can be changed. It is quite convenient to use. In particular, after the round table is deformed into a square table, the sector plate 14 is folded under the square table formed by the triangular plate 13 and the square substrate 11, and there is no need to reduce the space for placing the legs after the user is seated, which is highly progressive. Incoming, this new model can be a triangle! The surface on the surface of the surface is squared and the surface of the square plate is the same color, and the sector plate 14 is in another color, so that the round table is turned into a square table, and the color tone is transformed. To sum up, the flip-type round square table provided by the new model fully complies with the novelty and progressive requirements of the patent M427853 » r, and applies in accordance with the law.
