Description

Technical Field

[0001] This utility model belongs to the field of mahjong machines and relates to a leveling device for the tile lifting plate of a mahjong machine. Background Technology

[0002] The existing methods for leveling the tile-lifting plate and the mahjong machine panel mainly involve placing some open shims under the tile-lifting plate or some self-adhesive film under the panel to adjust their flatness. During the leveling process, the panel and tile-lifting plate must be repeatedly removed, and the screws loosened and tightened again. The leveling process is cumbersome and time-consuming. Summary of the Invention

[0003] In order to overcome the shortcomings of the existing leveling method for the tile lifting plate and the mahjong machine panel, which is cumbersome and time-consuming, this utility model provides a mahjong machine tile lifting plate leveling device that is more convenient and faster to adjust.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A leveling device for a mahjong machine's tile-lifting plate includes a tile-lifting plate and a pushing assembly. The upper moving end of the pushing assembly is connected to the tile-lifting plate, and the lower part of the pushing assembly is mounted on the mahjong machine's base plate. The leveling device also includes internal and external threaded bolts. Two height adjustment holes are provided on both the left and right sides of the mahjong machine's base plate. The internal and external threaded bolts are screwed into the height adjustment holes and connected to damping blocks that restrict their rotation. The damping blocks are connected to the bottom surface of the mahjong machine's base plate. The upper surface of the internal and external threaded bolts is a large flange that supports the height adjustment feet of the pushing assembly. A recessed hole is provided on the top surface of the internal and external threaded bolts, and the recessed hole has an operating part for a tool to rotate the internal and external threaded bolts. The height adjustment feet have through holes. The through holes and the height adjustment holes are concentrically arranged, and a fastening bolt passes through the through hole and is threaded to the inner wall of the internal and external threaded bolts.

[0006] Furthermore, the mahjong machine base plate is provided with a fixing hole on each of its left and right sides. The two height adjustment holes are symmetrically arranged on the inner and outer sides of the fixing holes. The pre-tightening bolt passes through the fixing foot of the lifting assembly and is installed in the fixing hole to fix the lifting assembly and the mahjong machine base plate.

[0007] Furthermore, the operating part of the recessed hole is a wrench hole, preferably an internal hex wrench hole.

[0008] The main advantages of this utility model are that adjustments are more convenient and quicker. Attached Figure Description

[0013] The present invention will now be further described with reference to the accompanying drawings.

[0014] Reference Figures 1-4 A leveling device for a mahjong machine's tile-lifting plate includes a tile-lifting plate 1 and a lifting assembly 2. The upper actuating end of the lifting assembly 2 is connected to the tile-lifting plate 1, and the lower part of the lifting assembly 2 is mounted on a large base plate 3 of the mahjong machine. The leveling device also includes internal and external threaded bolts 4. The large base plate 3 of the mahjong machine has two height adjustment holes 31 on both its left and right sides. The internal and external threaded bolts 4 are screwed into the height adjustment holes 31, and the internal and external threaded bolts 4 pass through the height adjustment holes 31 and are connected to a damping block 3 used to limit the rotation of the internal and external threaded bolts. 2. The damping block 32 is connected to the bottom surface of the mahjong machine base plate 3; the upper surface of the internal and external threaded bolt 4 is a large flange 41, the large flange 41 supports the height adjustment foot 21 of the lifting assembly 2, the top surface of the internal and external threaded bolt 41 is provided with a recessed hole, the recessed hole is provided with an operating part 42 for tools to rotate the internal and external threaded bolt, the height adjustment foot 21 is provided with a through hole, the through hole and the height adjustment hole 31 are concentrically arranged, and the fastening bolt 5 passes through the through hole and is threaded to the inner wall of the internal and external threaded bolt 4.

[0015] Furthermore, a fixing hole 33 is provided on each of the left and right sides of the mahjong machine base plate 3. The two height adjustment holes 31 are symmetrically arranged on the inner and outer sides of the fixing hole 33. The pre-tightening bolt 6 passes through the fixing foot 22 of the lifting assembly 2 and is installed in the fixing hole 33 to fix the lifting assembly 2 and the mahjong machine base plate 3.

[0016] Furthermore, the operating part 42 of the recessed hole is a wrench hole, preferably an internal hex wrench hole.

[0017] The working process of this embodiment is as follows: The lifting assembly 2 is placed above the mahjong machine's base plate 3. The mahjong machine's base plate 3 is provided with height adjustment holes 31. An internal or external threaded bolt 4 is screwed into each height adjustment hole 31. A damping block 32 is also provided directly below the height adjustment hole 31. The internal or external threaded bolt 4 is also screwed into the damping block 32 at the same time. The function of the damping block 32 is to prevent the internal or external threaded bolt from rotating when the bolt is tightened. The upper surface of the internal or external threaded bolt 4 is a large flange 41. The function of the large flange 41 is to support the height adjustment foot 21 of the lifting assembly 2. When the internal or external threaded bolt 4 is screwed upward, the height adjustment foot 21 on this side will be pushed upward. When the internal or external threaded bolt 4 is screwed downward, the height adjustment foot 21 on this side will be lowered. As the height of the height adjustment foot of the lifting assembly changes, the height of the tile-lifting plate on this side is also adjusted, so that the tile-lifting plate is flush with the mahjong machine panel, achieving the leveling function. Finally, using a three-piece preload bolt 6 with elastic washers, pass through the mounting holes of the fixing feet 22 and screw it into the fixing holes 33 of the mahjong machine base plate 3 to elastically fix the lifting assembly 2 onto the mahjong machine base plate 3.

[0018] The embodiments described in this specification are merely examples of implementations of the inventive concept and are for illustrative purposes only. The scope of protection of this utility model should not be considered limited to the specific forms described in these embodiments; rather, it extends to equivalent technical means that can be conceived by those skilled in the art based on the inventive concept.
