Description

Technical Field

[0001] The utility model relates to the field of mahjong machines, in particular to a rotary card-returning door structure. Background Art

[0002] As an entertainment and gaming device that is deeply loved by the general public, the automatic mahjong machine uses magnetic mahjong tiles to provide users with a more comfortable playing experience. Existing automatic mahjong machines usually use two sets of magnetic mahjong tiles, and basically adopt the traditional way of stacking all mahjong tiles in front of the user. This determines that this type of automatic mahjong machine requires four sets of lifting mechanisms, which not only makes the structure of the movement of the automatic mahjong table (i.e., the mahjong host) itself more complicated, but also the space and weight of the mahjong host cannot be reduced, making it difficult to achieve lightweight and portable mahjong machines.

[0003] Therefore, the applicant designed a single-port machine, an automatic mahjong machine with the announcement number CN107376336B. Only one card outlet and a card lifting mechanism are needed, and only one deck of mahjong tiles can meet the normal use of the user, which greatly reduces the volume and weight of the mahjong machine. Since the card outlet of the single-port machine occupies the middle area, and the traditional mahjong machine has a lifting opening in the middle for pushing mahjong tiles to return the tiles, a new opening structure is needed for returning the tiles. Utility Model Content

[0004] In view of the above problems, the utility model aims to provide a rotating card return door structure.

When it is necessary to return cards, the driving mechanism can drive the revolving door disc to rotate so that the inner fan ring notches and the outer fan ring notches correspond to form through holes. When it is necessary to put cards on, the driving mechanism can drive the revolving door disc to rotate so that the inner fan ring notches and the outer fan ring notches are staggered to form a closed structure.

[0006] Preferably, a transmission tooth is provided on the outer side of the swing door disc, and the driving mechanism is driven and meshed with the transmission tooth on the swing door disc through the driving gear thereon.

DETAILED DESCRIPTION

[0017] The utility model of the present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. In order to clearly and completely describe the technical solution, the following embodiments are selected for illustration; based on the contents recorded in this application, other embodiments obtained without creative work are all within the scope of protection of this utility model.

[0018] In the following embodiments, it should be noted that the terms "upper", "lower", "left", "right", "inside", "outside", "top / bottom" and other orientations or positional relationships are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of clearly describing the present embodiment, rather than indicating or implying that the device or element referred to must have a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0019] like Figure 1-4 As shown, the specific embodiment described in the utility model is a rotating card return door structure to ensure that the mahjong machine can smoothly perform card return and card loading operations. The rotating card return door structure mainly includes a disc shell 1 and a driving mechanism 2 arranged in the middle of the mahjong machine. The disc shell 1 is provided with more than two outer fan ring notches 101, and a revolving door disk 3 is arranged in the disc shell 1. The driving mechanism 2 is drivingly connected to the revolving door disk 3, and the revolving door disk 3 is also correspondingly provided with more than two inner fan ring notches 301. When it is necessary to return cards, the driving mechanism 2 can drive the revolving door disk 3 to rotate so that the inner fan ring notches 301 and the outer fan ring notches 101 correspond to form a through hole. When it is necessary to load cards, the driving mechanism 2 can drive the revolving door disk 3 to rotate so that the inner fan ring notches 105 and the outer fan ring notches 101 are staggered to form a closed structure. The disc shell 1 is the main external frame of the mahjong machine's card return door structure, providing a fixed space so that the internal revolving door disc 3 can rotate within this space. The revolving door disc 3 rotates through the driving mechanism 2, and can accurately control the alignment or stagger of the inner fan-shaped notch 301 and the outer fan-shaped notch 101, thereby realizing the functions of returning and loading cards.

[0020] The drive mechanism 2 is composed of a motor, a drive gear 201 and other components to provide stable rotational force and precise control. The drive mechanism 2 is connected to the control system and receives instructions from the control system to perform corresponding operations. Specifically, a transmission tooth 302 is provided on the outer side of the swing door disc 3, and the drive mechanism 2 is driven and meshed with the transmission tooth 302 on the swing door disc 3 through the drive gear 201 thereon.

[0021] A circle of circular plate 102 corresponding to the control panel of the mahjong machine is arranged in the middle of the circular plate 102, and a central card outlet 103 corresponding to the card lifting mechanism is arranged in the middle of the circular plate 102. The circular plate 102 is located in the middle of the circular plate 1, which corresponds to the control panel and provides a central card outlet 103 at a central position. The card outlet is a channel for the mahjong cards to be lifted out from the inside and displayed to the user. The card lifting mechanism is a mechanism in the mahjong machine for lifting the mahjong cards from the internal card library to the central card outlet 103. The control panel is the operating interface of the mahjong machine. The user inputs instructions by touching or pressing buttons to control various functions of the mahjong machine.

[0022] A circle of skirt plate 104 is arranged on the outside of the disc housing 1, and a notch 105 is arranged on the skirt plate 104, through which the driving gear 201 can pass to engage with the inner swing door disc 3; the main function of the skirt plate 104 is to provide the notch 105 for the driving gear 201 to pass through, so that the driving gear 201 can engage with the inner swing door disc 3, thereby driving the rotation of the swing door disc 3. The disc housing 1 is provided with fixing protrusions 106 around it, and the fixing protrusions 106 are provided with fixing holes 107. The design of the fixing holes 107 is mainly used to fix the disc housing 1 on other structures or bases, thereby ensuring the stability of the entire mahjong machine.

[0023] A positioning hole is provided on one side of the inner ring notch 301 of the swing door plate 3, and an infrared sensor is provided below the positioning hole. The infrared sensor is mainly used to detect and identify the state of foreign matter and transmit this information to the control system. The control system performs corresponding calculations and controls based on this information to ensure the smooth progress of the mahjong game.

[0024] A concave annular groove is provided in the middle of the revolving door disc 3, so that the revolving door disc 3 can be movably mounted on the annular plate 4 of the bracket in the middle of the mahjong machine through the concave annular groove, ensuring the stable rotation and positioning of the revolving door disc 3. This design not only ensures the stability of the revolving door disc 3, but also ensures that it can rotate flexibly to perform the tasks of returning and placing cards. The revolving door disc 3 and the annular plate 4 are both polyoxymethylene resin structures with self-lubricating functions. The polyoxymethylene resin structure has high hardness, high wear resistance, low friction coefficient and good fatigue resistance. Using this material to make the revolving door disc 3 and the annular plate 4 can ensure that they can maintain low friction resistance and reduce wear when performing frequent rotational movements, thereby extending the service life.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any minor modifications, equivalent substitutions and improvements made to the above embodiments based on the technical essence of the present invention should be included in the protection scope of the technical solution of the present invention.
