[0022] It can be understood that the panel fixing piece 210 is used to connect the mahjong machine panel, and the stand column 100 is used to support the mahjong machine panel after the mahjong machine panel is connected with the panel fixing piece 210, so that the mahjong machine panel can rotate relative to the stand column 100, and then the opening and closing of the mahjong machine panel are realized. In an embodiment, the thickness of the panel fixing piece 210 is 2.3 mm; the thickness of the first connecting piece 110 is 1.65 mm; so as to ensure the stable support of the mahjong machine panel. The first abutting groove 221 and the second abutting groove 222 are located on the opposite sides of the second connecting part 223 respectively. When the panel fixing piece 210 is in the closed state, the first abutting groove 221 abuts against the limiting part 112; when the panel fixing piece 210 is in the open state, the second abutting groove 222 abuts against the limiting part 112, the third abutting groove 224 provided on the second connecting piece 220 is a screw hole opening gap in a specific angle, the mahjong machine panel can be directly taken out from the machine at the specific angle, which is convenient for the detection and maintenance of the third party, and the mahjong machine panel can also be installed according to the specific angle, which saves the installation time and improves the efficiency. The hook 225 provided on the second connecting part 223 is shortened in length, which is convenient for taking out the mahjong machine panel from the mahjong machine. The preset angle is the angle of the panel fixing piece 210 when the panel fixing piece 210 rotates from the position where the first abutting groove 221 abuts against the limiting part 112 to the position where the second abutting groove 222 abuts against the limiting part 112. The limiting part 112 is located on the side of the first connecting piece 110 close to the second connecting piece 220, so that the limiting part 112 can abut against the first abutting groove 221 and the second abutting groove 222. The limiting part 112 can be provided with a protruding structure such as a sheet, a column or a point, as long as it can be used to abut against the first abutting groove 221 and the second abutting groove 222, so as to limit the angle of rotation of the panel fixing piece 200.

[0023] It can be understood that the connecting piece 300 includes but is not limited to a bolt and nut, a pin or a buckle, etc., as long as it can be provided in the first through hole and the second through hole to make the first connecting part 111 and the second connecting part 223 rotatably connected. In an embodiment, the connecting piece 300 includes a connecting bolt and a connecting nut matched with the connecting bolt; the connecting bolt is provided in the first through hole and the second through hole, and is screwed with the connecting nut, so as to make the first connecting part 111 and the second connecting part 223 rotatably connected. It can be understood that the stand column 100 and the panel fixing piece 200 are connected through the connecting bolt and the connecting nut, which has simple structure, convenient operation and low cost.

[0024] Further, the connecting bolt has a diameter of 4 mm, and the connecting nut is an anti-skid nut, so that the gap between the first connecting plate 110 and the second connecting plate 220 can be controlled as needed, avoiding the first connecting plate and the second connecting plate 220 from rotating jammed due to being connected too tightly or from shaking due to being connected too loosely.

[0025] It can be understood that the column 100 is used to support the mahjong machine panel after the mahjong machine panel is connected with the panel fixing plate 210, and therefore, in order to avoid the column 100 from being bent and deformed during the supporting process, the column 100 is composed of the first connecting plate 110 and the structural plate 120, and the structural plate 120 is arranged perpendicularly to the first connecting plate 110, so as to ensure the supporting strength of the column 100 on the mahjong machine panel. After the structural plate 120 is connected perpendicularly to the first connecting plate 110, an installation space for installing elements such as a mahjong blocking plate seat rear cover, a panel and a reinforcing rib is formed. The structural plate 120 is located at one end of the first connecting part 111 close to the limiting part 112, that is, the first connecting part 111 is located on the side of the vertical plane where the structural plate 120 is located away from the limiting part 112, and the first connecting part 111 is located outside the installation space, so as to avoid the connecting piece 300 installed on the first connecting part 111 from interfering with the elements such as the blocking plate seat rear cover, the panel and the reinforcing rib in the installation space.

[0026] In an embodiment, the preset angle is 90 degrees, the limiting part 112 is provided with a third through hole, a limiting piece 400 is arranged in the third through hole and protrudes from one end of the limiting part 112 towards the second connecting part 223, the column type hinge structure further comprises a damping piece arranged between the first connecting part 111 and the second connecting part 223, and the first connecting plate 110 is further provided with an installation part 113 for connecting a mahjong machine bottom plate. The installation part 113 is located at one end of the first connecting plate 110 away from the first connecting part 111, and the panel fixing plate 210 is arranged perpendicularly to the second connecting plate 220.

[0027] It can be understood that the preset angle is 90 degrees, and generally the mahjong machine is horizontally placed on the ground. After the limiting part 112 abuts against the first abutting groove 221, the panel fixing piece 210 is in a closed state, that is, the relative angle between the panel fixing piece 210 and the mahjong machine bottom plate is 0 degrees. After the limiting part 112 abuts against the second abutting groove 222, the panel fixing piece 210 is in an open state, and at this time, the relative angle between the panel fixing piece 210 and the mahjong machine plate is greater than 90 degrees, so that the mahjong machine panel installed on the panel fixing piece 210 can be kept in an open state without being closed under the action of gravity. The relative angle between the panel fixing piece 210 and the mahjong machine bottom plate is less than or equal to 100 degrees, which can avoid increasing the fatigue degree of the panel fixing piece 210 in the open state, avoid the panel fixing piece 210 from being broken, and thus prolong the service life of the panel fixing piece 210.

[0028] Further, the preset angle is 100 degrees, that is, after the limiting part 112 abuts against the second abutting groove 222, the relative angle between the panel fixing piece 210 and the mahjong machine bottom plate is 100 degrees, so as to keep the mahjong machine panel slightly outwardly inclined, which not only improves the stability of the mahjong machine panel in the open state, but also avoids damaging the mahjong machine panel due to too large opening angle.

[0029] It can be understood that the stand-type hinge structure further comprises a damping member (not shown in the figure), which is arranged between the first connecting part 111 and the second connecting part 223. It can be understood that the damping member includes but is not limited to one or more of a damping ring (friction damping) or a circlip (elastic damping), as long as the mahjong machine panel connected with the panel fixing block can be easily lifted when being lifted and slowly falls down when falling. In an embodiment, the damping member is a damping ring, and the first connecting part 111 is provided with a containing groove around the first through hole, and the damping member is installed in the containing groove, so as to facilitate the assembly of the damping member and improve the assembly efficiency. Further, the depth of the containing groove is 0.3 mm, and the damping member is a nylon damping ring with an outer diameter of 10 mm, an inner diameter of 6 mm and a thickness of 1.5 mm. In another embodiment, the damping member can also be a circlip. The elastic force provided by the circlip is in the direction in which the panel fixing piece 210 is opened, and the elastic force is smaller than the gravity of the mahjong machine panel, so that the mahjong machine panel can slowly fall down to a position parallel to the mahjong machine bottom plate when falling down, and the damping member can provide elastic force in the opening direction when being lifted, so as to easily lift the mahjong machine panel.

[0030] It can be understood that the mounting portion 113 is located on the first connecting sheet 110 away from the first connecting portion 111, that is, away from the panel fixing sheet 210, so that the upright column 100 can support the mahjong machine panel installed on the panel fixing sheet 210 on the mahjong machine bottom plate. The connection mode of the mounting portion 113 and the mahjong machine bottom plate includes but is not limited to one or more of bolt connection, buckle connection, pin connection, etc.

[0031] In the mahjong machine, the first abutting groove 221 and the second abutting groove 222 are respectively abutted with the limiting portion 112 arranged on the first connecting sheet 110 of the upright column 100, so as to limit the included angle of the rotation of the panel fixing sheet 210 of the panel fixing member 200 along the rotation shaft of the first connecting portion 111 and the second connecting portion 223 to be a preset angle, and then the opening state of the mahjong machine panel connected with the panel fixing sheet 210 is maintained, the mahjong machine panel can be taken out along a specific angle through the third abutting groove 224, the third party detection and maintenance of the mahjong machine are very convenient, the disassembly time is saved, the efficiency is improved, and the installation is also convenient.

[0032] The above is only a preferred specific embodiment of the mahjong machine, but the protection scope of the mahjong machine is not limited to this, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the utility model concept of the mahjong machine within the technical range disclosed by the mahjong machine, which should be covered in the protection scope of the mahjong machine.
