DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] See also Figure 1-Figure 3 The utility model provides a technical solution: an automatic mahjong machine that is easy to adjust the height, including a rectangular hollow cylinder 2, a limit frame 16 and a connecting block 13. The limit frame 16 is installed at the lower end of the interior of the rectangular hollow cylinder 2. The first straight rack plate 11 and the second straight rack plate 12 are respectively slidably provided on the left and right sides of the interior of the rectangular hollow cylinder 2. A driving gear 9 is installed on the left side of the middle of the rectangular hollow cylinder 2 through a first metal shaft. A driven gear 10 is installed on the right side of the middle of the rectangular hollow cylinder 2 through a second metal shaft. A small brake motor 6 and a lifting switch 8 are installed at the front end of the rectangular hollow cylinder 2. An electromagnetic brake 7 is installed on the right side of the rectangular hollow cylinder 2. The connecting block 13 is slidably located in the rectangular hollow cylinder 2. On the upper side of the interior of the hollow cylinder 2, the lower ends of the connecting blocks 13 are fixed to the first straight rack plate 11 and the second straight rack plate 12. A connecting plate 14 is horizontally welded to the upper end of the connecting block 13. The upper end of the connecting plate 14 is fixed with an automatic mahjong machine body 15 by bolts. Bar-shaped through grooves 3 are provided on the left and right ends of the rectangular hollow cylinder 2. The first straight rack plate 11 and the second straight rack plate 12 are fixed with movable prompt blocks 4 at the lower ends relative to the outside. The two movable prompt blocks 4 are respectively slidably located in the two bar-shaped through grooves 3. This design solves the problem that most of the original mahjong machines have fixed structures and their height cannot be adjusted according to people's actual needs and usage habits, which brings inconvenience to use and affects people's experience.

[0019] As the first embodiment of the present invention: an anti-falling base 1 is installed at the lower end of the rectangular hollow tube 2, and prompt scales 5 are set at the left and right ends of the rectangular hollow tube 2. The added prompt scales 5 can be used to know the rising distance of the moving prompt block 4.

[0020] The driving gear 9 and the driven gear 10 are meshed with each other, and the added driving gear 9 can drive the driven gear 10 to mesh and rotate.

[0021] The left end of the driving gear 9 is engaged with the first spur rack plate 11 for transmission, and the right end of the driven gear 10 is engaged with the second spur rack plate 12 for transmission. When the added driving gear 9 rotates clockwise, the first spur rack plate 11 can be driven to move upward, and the driven gear 10 can also be driven to engage and rotate counterclockwise, and the counterclockwise rotation of the driven gear 10 can drive the second spur rack plate 12 to move upward.

[0022] The shaft end of the small brake motor 6 is in transmission connection with the first metal shaft and the driving gear 9. The added small brake motor 6 can drive the driving gear 9 to rotate through the first metal shaft.

[0023] The left and right ends of the limit frame 16 slide against the first straight rack plate 11 and the second straight rack plate 12 respectively. The added limit frame 16 can limit the first straight rack plate 11 and the second straight rack plate 12, so that the first straight rack plate 11 and the second straight rack plate 12 move up and down more smoothly.

[0024] As a second embodiment of the present invention: when the height of the automatic mahjong machine body 15 needs to be increased, the lifting switch 8 is clicked to start the small brake motor 6 and the electromagnetic brake 7 (Note: the circuits and electronic components involved in the present invention are all prior art and can be fully implemented by those skilled in the art without further explanation). The small brake motor 6 drives the driving gear 9 to rotate clockwise via the first metal shaft. When the driving gear 9 rotates clockwise, it can drive the first spur rack plate 11 to move upward and also drive the driven gear 10 to engage and rotate counterclockwise. The counterclockwise rotation of the driven gear 10 can drive the second spur rack plate 12 to move upward. The first and second spur rack plates 11 and 12 that move upward can drive the automatic mahjong machine body 15 to move upward through the connecting block 13 and the connecting plate 14, thereby achieving the height adjustment of the automatic mahjong machine body 15. In this process, the two moving prompt blocks 4 follow and move upward within the two bar-shaped through slots 3. By observing the moving prompt block 4 and the prompt scale 5, the height of the device can be known.

[0025] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, it is intended that all changes that fall within the meaning and range of equivalents of the claims are included in the present invention. Any reference signs in the claims should not be construed as limiting the claim to which they relate.
