[0037] The structure, features, and advantages of an exquisite Go board are described in detail below:
[0038] exist Figure 1 As can be seen, the chessboard is bordered with a wavy design made of high-quality hardwood (its cross-sectional shape can be seen in the image). Figure 4 With its antique traditional style, the dotted line in the middle indicates the "well" shaped wooden frame structure, which can evenly support the main body of the chessboard and firmly fix the surrounding frame. There are reinforcing blocks 3 at the four corners on the inside of the four frame strips to make the frame more sturdy.
[0039] from Figure 1 , Figure 3 and Figure 4As can be seen, the ceramic panel has intermittent shallow grooves on all four sides, and the corresponding shallow grooves are also cut on the sides of the steps on the inner four sides of the chessboard-shaped wooden frame. During assembly, the small grooves of both the ceramic panel and the outer wooden frame are filled with strong adhesive, which then tightly binds the two together. After the adhesive solidifies, the two are very firmly bonded.
[0040] from Figure 4 , Figure 5 and Figure 8 It can be seen that: at the joints of the wooden strips around the outer frame of the chessboard, besides... Figure 8 In addition to the mortise and tenon structure, there is a reinforcing wooden block 3 on the inside of the corner, which is held together by four wood screws 5 to tighten the perpendicular frame strips. The base plate 4 of the chessboard is fixed to the inner step of the bottom of the wooden frame with small nails.
[0041] from Figure 5 and Figure 6 It can also be seen that the ends of the "well"-shaped wooden strip structure 9 are fixed to the outer wooden frame of the chessboard with double straight tenons, which can ensure that the wooden frame will not deform. The "well"-shaped wooden strip structure 9 can effectively support the ceramic panel.
[0042] from Figure 7 The double straight tenons at the ends of the "well"-shaped wooden frame facilitate its integration with the outer wooden frame of the chessboard. The two sets of perpendicular wooden strips of the "well"-shaped wooden frame are connected by a "cross" interlocking tenon structure, which secures them together.
[0043] exist Figure 8 In the middle, the male tenon 2′ and the female tenon 2″ are made using a dovetail joint structure, and the mating surfaces 2″′ other than the mortise and tenon are pressed together at a 45° angle.
[0044] In the wooden structure of the chessboard, when the mortise and tenon joints are joined together, adhesive must be applied to the contact surfaces of the two parts before they are tightly fitted together.
[0045] In summary, the advantages of a chessboard are its clean surface, clear lines, beautiful, simple, and elegant frame, and its sturdy wooden structure, which provides players with a very pleasant experience.
