[0030] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technical personnel in this field without creative work are within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the present invention can be combined interactively without conflicting with each other.

[0031] Reference Figures 1 to 7 This embodiment provides a rotatable chessboard, comprising a base plate 1, a cover plate 2, and a gear 3. The cover plate 2 is connected to the base plate 1 to form a mounting cavity, and the gear 3 is arranged in the mounting cavity.

[0032] Specifically, the bottom plate 1 is provided with a plurality of connection holes 10 , and the cover plate 2 is provided with a plurality of connection posts 20 , and the connection posts 20 are adapted to the connection holes 10 .

[0033] Specifically, the gear 3 includes a driving gear 30 and a plurality of first driven gears 31. The plurality of first driven gears 31 are arranged around the driving gear 30 and mesh with the driving gear 30. The upper surface of the cover plate 2 is provided with a plurality of first placement areas 21 and a plurality of openings 22. The driving gear 30 and the first driven gears 31 extend through the openings 22. A second placement area 311 is provided on the upper surface of the first driven gear 31. The first and second placement areas 21 and 311 form the chessboard.

[0034] It is understood that the first placement area 21 and the second placement area 311 constitute a chessboard, and the user places chess pieces on the first and second placement areas 21 and 311 to form a chess game and play the game. When a game is over, the user can rotate the driving gear 30, which drives the plurality of first driven gears 31 to rotate, causing the relative positions of the plurality of second placement areas 311 and the first placement area 21 to change. The positions of the chess pieces placed by the user in the second placement areas 311 also change, thereby changing the chess game situation. The user can then play the game again on the changed chess game.

[0035] Compared to existing chessboards, the user only needs to rotate the driving gear 30 once to drive the multiple first driven gears 31 to rotate simultaneously, causing the positions of the multiple second placement areas 311 to change simultaneously. This saves time and effort and allows for quick and easy disruption of the chess game. Furthermore, the chessboard provided by this embodiment helps cultivate the user's thinking ability. The user is required to consider not only the chess game before the board changes, but also the chess game after the multiple second placement areas 311 have rotated, thereby increasing the difficulty and fun of the game.

[0036] Furthermore, the chessboard also includes a plurality of second driven gears 32 and a plurality of third driven gears 33. Four first driven gears 31 surround the driving gear 30 and mesh with the driving gear 30. Each first driven gear 31 is meshed with a second driven gear 32, and each second driven gear 32 is meshed with a third driven gear 33 on opposite sides. A fourth placement area 331 is provided on the upper surface of the third driven gear 33. The fourth placement area 331, the first placement area 21, and the second placement area 311 form the chessboard. The plurality of second driven gears 32 are located below the first placement area 21.

[0037] In this embodiment, the third driven gear 33 has the same structure as the second driven gear 32 .

[0038] Furthermore, a third dropping area 23 is provided on the cover plate 2, and is located at the intersection of the first dropping area 21, the second dropping area 311, and the fourth dropping area 331. When the second dropping area 311 and the fourth dropping area 331 rotate, the arrangement of the third dropping area 23, the second dropping area 311, and the fourth dropping area 331 will change.

[0039] It is understood that the driving gear 30, the first driven gear 31, the second driven gear 32, and the third driven gear 33 form a linkage relationship. The driving gear 30 is used to drive the first driven gear 31 to rotate, the first driven gear 31 is used to drive the second driven gear 32 to rotate, and the second driven gear 32 is used to drive the third driven gear 33, which is farther away from the driving gear 30, to rotate. Similarly, the chessboard of this embodiment can be equipped with several more sets of meshing gears 3 to provide a larger chessboard surface. The user can still adjust the chessboard position by simply turning the driving gear 30 once.

[0040] In this embodiment, a first recess 11, a second recess 12, a third recess 13 and a fourth recess are provided on the base plate 1. The driving gear 30 is provided in the first recess 11, the first driven gear 31 is provided in the second recess 12, the second driven gear 32 is provided in the third recess 13, and the third driven gear 33 is provided in the fourth recess.

[0041] Specifically, a cylindrical first limiting structure 111 is provided in the first recess 11, and a cylindrical second limiting structure 301 is provided at the bottom of the driving gear 30. The outer contour of the second limiting structure 301 matches the inner contour of the first limiting structure 111, and the second limiting structure 301 is inserted into the inner circumference of the first limiting structure 111. The first limiting structure 111 is used to confine the driving gear 30 in the first recess 11 to prevent it from deflecting during rotation.

[0042] Furthermore, a plurality of positioning grooves 112 are evenly distributed around the periphery of the first recess 11, and a positioning post 302 is provided at the bottom of the driving gear 30, and the positioning post 302 is inserted into the positioning groove 112. When the user rotates the driving gear 30, the positioning post 302 can be inserted into different positioning grooves 112.

[0043] In this embodiment, there are eight positioning slots 112 and eight positioning posts 302. This indicates that the angle between each two adjacent positioning slots 112 is 45 degrees. When the user rotates the driving gear 30 45 degrees, the positioning post 302 can move into the adjacent positioning slot 112. The user can hear the sound of the positioning post 302 plugging into the positioning slot 112, thereby determining whether the driving gear 30 has rotated into place. During a chess game, the two players can agree on the rotation angle. For example, one player rotates the driving gear 30 45 degrees, causing the second and fourth placement areas 311 and 331 to rotate. After the rotation is completed, the other player has the right to place a move.

[0044] In this embodiment, the driving gear 30 is provided with a raised gripping portion 303 on its surface, and a plurality of anti-slip strips 304 are evenly distributed around the periphery of the gripping portion 303. The provision of the anti-slip strips 304 can increase the friction between the user's hand and the gripping portion 303, making the grip more stable and less prone to hand slippage. In addition, it can also help the user more accurately control the force and direction of the rotation of the driving gear 30.

[0045] In actual applications, different numbers of the positioning slots 112 and the positioning posts 302 can be customized according to user needs.

[0046] Since the first driven gear 31 and the third driven gear 33 have the same structure, the second recess 12 and the fourth recess also have the same structure.

[0047] Specifically, in this embodiment, a cylindrical third limiting structure 121 is provided in the second recess 12, and a cylindrical fourth limiting structure 312 is provided at the bottom of the first driven gear 31. The inner circumference of the third limiting structure 121 matches the outer circumference of the fourth limiting structure 312, and the third limiting structure 121 is sleeved on the outer circumference of the fourth limiting structure 312. The third limiting structure 121 is used to confine the first driven gear 31 in the second recess 12 to prevent it from deflecting during rotation.

[0048] Furthermore, a rotating shaft 131 is provided in the third recess 13, and a limiting hole 321 is provided in the middle of the second driven gear 32. The rotating shaft 131 is inserted into the limiting hole 321, and the second driven gear 32 can rotate relative to the rotating shaft 131. The present utility model provides a rotatable chessboard. By providing meshing driving gears 30 and driven gears 3, the user can rotate multiple rotating plates at once to change the position of the chessboard's placement area, thereby quickly adjusting the chessboard situation and improving the user experience.

[0049] It is understandable that those skilled in the art can, under the guidance of the above embodiments, combine various implementation methods in the above embodiments to obtain technical solutions of multiple implementation methods.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
