Technical Field
[0001] The utility model relates to the technical field of chessboards, in particular to a lifting and folding chessboard. Background Art
[0002] Xiangqi (English name: Xiangqi) is a traditional Chinese chess variety and also an internationally recognized chess variety, belonging to a two-player adversarial chess game. Xiangqi uses a square grid-shaped chessboard and round chess pieces. The chess box and the chess pieces are two independent objects. The chess box is generally made of wood, cannot be folded, and has a large volume. At the same time, the chess pieces also need to be stored and placed in a special chess box, which is easy to lose and forget to carry. Content of the Utility Model
[0003] Objective of the utility model: In order to overcome the defects of the prior art, the utility model provides a lifting and folding chessboard. When the chessboard is folded, the two chessboard pages can sink to vacate a space for accommodating the chess pieces.
[0004] Technical solution of the utility model: A lifting and folding chessboard includes a first box part, a second box part, and a middle plate located between the two box parts. The two box parts are rotatably connected to the middle plate so that the two box parts can be folded or unfolded. Each box part has an outer frame and a chessboard placed inside the outer frame. When the two box parts are rotated and folded, the two chessboard pages will sink inside the corresponding outer frame to vacate a space for accommodating the chess pieces. When the two box parts are rotated and unfolded, the two chessboard pages will rise inside the corresponding outer frame and be combined with the middle plate to form a chessboard plate.
[0005] By adopting the above technical solution, when the chessboard is folded, the two chessboard pages can sink to vacate a space for accommodating the chess pieces, making the chess pieces not easy to lose, and the volume of the two box parts becomes smaller and more convenient to carry after being rotated and folded. When the chessboard is unfolded, the two chessboard pages rise to be flush with the middle plate to form a chessboard plate, and can also be flush with the upper surface of the outer end to obtain a larger operation plane. The chessboard can be used for playing chess immediately when it is unfolded, which is very convenient and fast, and has good practicability.
[0006] Preferably, the opposite ends of the two chessboard pages are respectively hinged to the middle plate, and there are protrusions and inclined grooves between the side walls of the two chessboard pages and the corresponding outer frames. The chessboard realizes lifting inside the outer frame through the cooperation of the protrusions and the inclined grooves.
[0007] Preferably, the chessboard and the middle plate are connected by a hinge, and there is also a groove area on the inner side wall of the outer frame for the hinge to move.
[0008] When folded, the outer frame drives the chessboard to rotate around the middle board. The middle board will pull the two chessboards. The protrusions of the chessboards slide down in the inclined grooves, realizing that the two chessboards automatically sink in the corresponding outer frames to vacate a space for accommodating the chess pieces. When unfolded, the protrusions of the chessboards slide up in the inclined grooves, gradually unfolding the chessboards. When fully unfolded, the travel of the protrusions in the inclined grooves just ends, and the chessboards are fully unfolded to form a plane flush with the middle board. When playing chess, since the chessboards only receive a vertically downward force, the convex columns will not slide down by themselves. Instead, they will form a fulcrum relying on the edge of the inclined groove to support the chessboards.
[0009] Preferably, a guiding inclined surface is provided on the inner end wall of the outer frame. By the opposite ends of the two chessboards respectively abutting against the guiding inclined surfaces of the corresponding outer frames, the guiding of the chessboards to incline and sink is realized.
[0010] Preferably, the opposite ends of the two outer frames are respectively hinged to the middle board, and are also driven by a gear set therebetween. The gear set is provided with a transmission gear on each of the corresponding two outer frames. The transmission gears are mounted on the outer frames via mounting shafts, and the two transmission gears are directly or indirectly meshed. The gear set transmission can drive the two outer frames to rotate synchronously, and the two chessboards can be lifted and lowered simultaneously, having good consistency and eliminating the need for the user to wait. And the structure is simple and the operation is convenient.
[0011] Preferably, a spacer sleeve is further provided between the transmission gear and the mounting shaft, and both ends of the spacer sleeve in the radial direction protrude outside the transmission gear. By both ends of the spacer sleeve in the radial direction protruding outside the transmission gear, extrusion of the end face of the transmission gear by other parts is avoided, enabling the transmission gear to rotate freely.
[0012] Preferably, the gear set further includes a gasket one sleeved on the two mounting shafts and pressing between one end of the spacer sleeve and the outer frame, and a gasket two sleeved on the two mounting shafts and pressing between the other end of the spacer sleeve and the shaft head of the mounting shaft.
[0013] Preferably, the mounting shaft penetrates between the outer frame and the middle board, and can realize the rotational connection between the two.
[0014] Preferably, the opposite ends of the two chessboards are both arc concave surfaces, the middle board has an arc convex surface adapted to the arc concave surface, and the outer frame is also in a "U" shape. Through the cooperation of the arc concave surface and the convex surface, the rotation of the two chessboards is facilitated.
[0015] Preferably, table legs are detachably mounted on the outer frame. The table legs can be installed when needed to support the height of the chessboard. Description of the Drawings

Specific implementation mode
[0031] The technical solution in this embodiment will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without any creative work belong to the scope of protection of the present utility model.
[0032] As Figure 1-14 shown, a lifting and folding chessboard of the present utility model includes a first box part A, a second box part B, and a middle plate C located between the two box parts. The two box parts are rotatably connected to the middle plate C so that the two box parts can be folded or unfolded; each box part has an outer frame 1 and a chessboard 2 placed inside the outer frame 1. When the two box parts are rotated and folded, the two chessboards 2 will sink inside the corresponding outer frames 1 to vacate a space for accommodating chess pieces; when the two box parts are rotated and unfolded, the two chessboards 2 will rise inside the corresponding outer frames 1 and be combined with the middle plate C to form a chessboard plate. The chessboard plate composed of the middle plate and the two chessboards, and the box frame composed of the two outer frames, the chessboard plate is located inside the box frame.
[0033] Specifically, the opposite ends of the two chessboards 2 are respectively hinged to the middle plate C. There are protrusions 31 and inclined grooves 32 between the side walls of the two chessboards 2 and the corresponding outer frames. The chessboard 2 realizes lifting inside the outer frame 1 through the cooperation of the protrusions 31 and the inclined grooves 32. The inclined grooves 32 are located on the inner side walls of the outer frames. The protrusions 31 are cams or sliding rods and are located on the chessboard 2. The chessboard 2 and the middle plate C are connected by a hinge 4. There is also a groove area 11 on the inner side wall of the outer frame 1 for the hinge 4 to move. There is a guiding inclined surface 12 on the inner end wall of the outer frame 1. By the opposite ends of the two chessboards 2 respectively abutting against the guiding inclined surfaces 12 of the corresponding outer frames 1, the guiding of the chessboard 2 to tilt and sink is realized. The opposite ends of the two outer frames 1 are respectively hinged to the middle plate C and are also driven by a gear set 5 therebetween.
[0034] Certainly, when the chessboard is unfolded, the chessboard 2 can also be lifted by a top wheel or a spring mechanism. When the chessboard is folded, the top wheel or the spring mechanism is accommodated inside the outer frame.
[0035] Specifically, the gear set 5 is provided with a transmission gear 51 corresponding to each of the two outer frames 1. The transmission gear 51 is mounted on the outer frame 1 via a mounting shaft 52, and the two transmission gears 51 are directly or indirectly engaged. A spacer sleeve 53 is further provided between the transmission gear 51 and the mounting shaft 52, and both ends of the spacer sleeve 53 in the radial direction protrude outside the transmission gear 51. The gear set 5 further includes gaskets. The first gasket 54 is sleeved on the two mounting shafts 52 and abuts between one end of the spacer sleeve 53 and the outer frame 1. The second gasket 55 is sleeved on the two mounting shafts 52 and abuts between the other end of the spacer sleeve 53 and the shaft head 521 of the mounting shaft 52. The mounting shaft 52 passes through the outer frame 1 and the middle plate C, and can realize the rotational connection between the two. The mounting shaft 52 is a screw and has a rod portion and a head. The rod portion passes through the second gasket, the spacer sleeve, the first gasket, and the outer frame, and the head is the shaft head 521 which abuts on the second gasket; the mounting shaft 52 is a screw rod and a nut screwed on the screw rod, and the nut is the shaft head 521 which abuts on the second gasket.
[0036] Specifically, the opposite ends of the two chessboards 2 are both arc concave surfaces 21, the middle plate C has an arc convex surface C1 adapted to the arc concave surface 21, and the outer frame is also in a "U" shape.
[0037] Specifically, table legs are also detachably mounted on the outer frame 1.
[0038] When the chessboard of the present utility model is folded, the outer frame 1 drives the chessboard 2 to rotate around the middle plate C, and the middle plate C will pull the two chessboards 2. The protrusions 31 of the chessboard 2 slide down in the inclined grooves 32, and the hinge 4 moves in the groove area 11, so that the two chessboards 2 automatically sink in the corresponding outer frames 1 to vacate a space for accommodating the chess pieces, making it difficult for the chess pieces to be lost. Moreover, after the two box parts are rotationally folded, the volume can be reduced and it is convenient to carry;
[0039] When the chessboard is unfolded, the protrusions 31 of the chessboard 2 slide up in the inclined grooves 32 to gradually unfold the chessboard 2. When it is fully unfolded, the stroke of the protrusions 31 in the inclined grooves 32 just ends, and the chessboard 2 is fully unfolded to form a plane flush with the middle plate C. When playing chess, since the chessboard 2 only receives a vertically downward force, the convex columns 31 will not slide down by themselves, but will form a fulcrum relying on the edge of the inclined grooves 32 to support the chessboard 2. The game can start immediately when the chessboard is unfolded, which is very convenient and fast and has good practicability.
[0040] The transmission of the gear set 5 can drive the two outer frames 1 to rotate synchronously, and the two chessboards 2 can be lifted and lowered simultaneously, having good consistency; by both ends of the spacer sleeve 53 protruding outside the transmission gear 51 in the radial direction, extrusion of other parts on the end face of the transmission gear 51 is avoided, enabling the transmission gear 51 to rotate freely.
