Description
Technical Field
[0001] The invention relates to the field of mahjong machines, and in particular to an anti-cheating dice keyboard and a mahjong machine thereof. Background Art
[0002] At present, mahjong tables are basically automatic mahjong machines, but electronic mahjong machines are easily manipulated by some illegal elements, that is, cheating. There are roughly two types of dice keyboards on the market. One is a mechanical dice tray. There is a cavity in the dice keyboard. A turntable driven by a motor is installed at the bottom of the cavity. The dice are placed on the turntable. The turntable rotates to drive the dice to roll. At present, some people will implant magnets in the dice, and then install electromagnetic coils around the cavity that can drive the dice to flip, so as to control the number of dice points; the other is an electronic dice tray, with dice printed on the top cover of the tray, and LED lights installed under the dice. The printed dice are illuminated by LED lights, but this structure is also easy to be manipulated passively, that is, the number of dice points can be easily controlled by modifying the LED lighting order. There is also a new dice keyboard that combines the above two dice rolling methods, such as a touch-type mahjong machine control panel with application number: 201820796754.6. No matter how the two dice rolling methods are combined, they are easy to be controlled manually. Summary of the invention
[0003] Aiming at the shortcoming that the points of dice rolling in the prior art are easily controlled artificially, the present invention provides an anti-cheating dice keyboard and a mahjong machine thereof.
[0004] In order to solve the above technical problems, the present invention is solved by the following technical solutions:
[0005] The invention discloses an anti-cheating dice keyboard, comprising a tray and a keyboard, wherein the keyboard is mounted on the tray, a circuit board and a motor are arranged in an inner cavity of the tray, a turntable is mounted on an output shaft of the motor, a circular array on an end surface of the circuit board is provided with at least 6×y lamps, y is an integer, and y≥2, a light guide hole for guiding light to the lamp is arranged on the keyboard, and the number of the light guide holes is the same as the number of the lamps, the turntable is arranged above the light guide hole, and the area where each light guide hole is directly projected onto the turntable is a light guide area, and the number of dice points is arranged in the light guide area, a first positioning member is fixed on the turntable, and a second positioning member is fixed on the keyboard, the first positioning member is magnetically connected to the second positioning member and positions the light guide area of the turntable on the light guide hole of the keyboard.
[0006] Traditional electronic dice trays print the dice numbers on the control panel of the tray, such as the glass touch screen of patent 201820796754.6, and the dice points are fixed. This dice keyboard prints the dice numbers on the turntable, the motor drives the turntable to rotate, and the lights are randomly lit by the program. Because the turntable rotates, people cannot know which number the lights will light up. It is multi-random and has a good anti-cheating effect.
[0007] Preferably, at least one of the first positioning member and the second positioning member is a magnetic positioning member, and positioning grooves are provided on the turntable and the keyboard. The first positioning member is installed in the positioning groove of the turntable, and the second positioning member is installed in the positioning groove of the keyboard.
[0008] The first positioning member and the second positioning member are mainly used to make the dice points face the light when the turntable stops, so as to ensure the effectiveness of dice rolling and prevent the dice numbers on the turntable from falling between the two lights. The first positioning member and the second positioning member are installed in a limited position through the positioning groove, so that the first positioning member and the second positioning member are fixed firmly.
[0009] Preferably, the first positioning member and the second positioning member are both gear-shaped positioning pieces, the positioning groove is a gear-shaped first positioning groove, the positioning piece is an integrated positioning piece, the positioning piece includes a positioning ring and a positioning head, the number of the positioning heads is the same as the number of the light guide holes, all the positioning heads are circularly arrayed on the side wall of the positioning ring, and when the turntable stops rotating, the positioning heads on the turntable are aligned one by one with the positioning heads on the keyboard.
[0010] Since the positioning piece is an integrated gear-shaped positioning piece, the positioning piece is easy to disassemble and assemble, and the positioning is highly accurate through the mutual attraction of two opposing positioning pieces. In order to allow the turntable to be randomly positioned on the keyboard and to allow the dice points to fall just above the lamp, the number of positioning heads on the first positioning piece and the number of positioning heads on the second positioning piece are the same. When the turntable stops, the positioning heads on the first positioning piece can correspond one-to-one with the positioning heads on the second positioning piece, so that the light guide area on the turntable is aligned one-to-one with the light guide hole on the keyboard.
[0011] Preferably, the first positioning member and the second positioning member are both cylindrical positioning blocks, the positioning grooves are cylindrical second positioning grooves, the number of second positioning grooves on the turntable and the keyboard is the same as the number of light guide holes, and a positioning block is installed in each second positioning groove. When the turntable stops rotating, the positioning blocks on the turntable are aligned one by one with the positioning blocks on the keyboard.
[0012] Since both the turntable and the keyboard are provided with the same number of positioning blocks as the second positioning grooves, the cylindrical positioning blocks are easy to process and have high production efficiency. The positioning is highly accurate by attracting each other through the two sets of positioning blocks facing each other. In order to allow the turntable to be randomly positioned on the keyboard and to allow the dice points to fall just above the lamp, the number of positioning blocks on the first positioning member is the same as that on the second positioning member. When the turntable stops, the positioning blocks on the first positioning member can correspond one-to-one with the positioning blocks on the second positioning member, so that the light guide area on the turntable is aligned one-to-one with the light guide hole on the keyboard.
[0013] Preferably, one of the first positioning member and the second positioning member is a gear-shaped positioning piece, and the other is a column-shaped positioning block. One of the positioning grooves on the turntable and the keyboard is a gear-shaped first positioning groove, and the other is a column-shaped second positioning groove. The number of the second positioning groove is at least one. The positioning piece is installed in the first positioning groove, and the positioning block is installed in the second positioning groove. The positioning piece is an integrated positioning piece. The positioning piece includes a positioning ring and a positioning head. The number of the positioning heads is the same as the number of the light guide holes. All the positioning heads are circularly arrayed on the side wall of the positioning ring. When the turntable stops rotating, the positioning block is aligned with the positioning head.
[0014] The positioning piece is an integrated gear-shaped positioning piece, which is easy to disassemble and assemble; the cylindrical positioning block is easy to process and has high production efficiency. The cylindrical positioning block can be randomly positioned with the positioning head on the positioning piece, so that the light guide area on the turntable is aligned with the light guide hole on the keyboard one by one, with high positioning accuracy.

[0016] The light guide seat is used to gather light and prevent light from leaking into other light guide areas, ensuring that the randomly selected light guide area on the turntable is fully illuminated.
[0017] Preferably, it also includes a motor seat for mounting the motor, the motor seat is detachably connected to the light guide seat, a wire hole is provided on the motor seat, and the motor wire on the motor is connected to the circuit board through the wire hole.
[0018] The motor is mounted on the light guide seat through the motor seat, and the motor installation stability is high, so that the turntable rotation stability is high. The wire hole is convenient for people to connect the motor to the circuit board.
[0019] Preferably, the keyboard further comprises a panel, which covers the disk body and is a plastic panel, a glass panel or a metal panel.
[0020] Preferably, a second through hole is provided at the center of the panel, the turntable extends into the second through hole, and the upper end surface of the turntable is flush with the upper end surface of the panel.
[0021] After the motor drives the turntable to rotate for a period of time, the motor stops outputting power. Since there are no dice on the turntable and due to inertia, the turntable can still rotate for a short period of time. In order to increase randomness, people can manually stop the turntable through the second through hole, which has a better anti-cheating effect.
[0022] A mahjong machine comprises a dice keyboard.
[0023] The present invention has significant technical effects due to the adoption of the above technical solution:
