DETAILED DESCRIPTION

[0025] In order to make the technical problems, technical solutions and beneficial effects solved by the present application more clearly understood, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application.

[0026] It should be understood that the terms "upper", "lower", "left", "right", "front", "back", "middle" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only used to facilitate the description of the present application and simplify the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0027] As Figures 1 to 7 shown, an embodiment of the present application provides a back-lit non-reinforced structure mahjong machine bottom plate, which comprises a bottom plate body 100 and a reinforcing plate 200; the bottom plate body 100 comprises an avoiding part 110 for arranging an avoiding hole 111, and a supporting part 120 located around the avoiding part 110 and used for mounting the reinforcing plate 200; the reinforcing plate 200 is provided with a stretching groove group 210 recessed to one side of the supporting part 120 and used for improving the structural strength of the reinforcing plate 200; and the reinforcing plate 200 is mounted on the supporting part 120 and used for strengthening the structural strength of the bottom plate body 100.

[0028] It can be understood that the avoiding part 110 can be used to install the center lifting mechanism and the large plate driving mechanism of the mahjong machine. The center lifting mechanism has small lifting stroke and small stress; and the motor in the large plate driving mechanism is in circular motion, and the required strength in the up-down direction is small. Therefore, the reinforcing plate 200 does not need to be arranged on the avoiding part 110. The avoiding hole 111 is used to avoid the interference between the components in the center lifting mechanism and the large plate driving mechanism and the bottom plate body 100 during movement. The supporting part 120 is located in the same plane as the avoiding part 110. The connection mode of the supporting part 120 and the avoiding part 110 includes but is not limited to one or more of the following modes such as one-piece forming, welding or bonding, as long as the supporting part 120 and the avoiding part 110 can be stably connected and located in the same plane. The reinforcing plate 200 is provided with a set of stretching grooves 210 which are recessed to the side of the supporting part 120 and are used to improve the structural strength of the reinforcing plate 200. The set of stretching grooves 210 can abut against the supporting part 120, and after abutting, the reinforcing plate 200 and the supporting part 120 are connected by welding or screwing. The structural strength includes but is not limited to bending deformation resistance and the like. The depth and shape of the set of stretching grooves 210 can be set according to actual conditions, as long as the structural strength of the reinforcing plate 200 can be improved to meet the structural strength requirement of the bottom plate body 100, and the screw holes or wire holes on the bottom plate body 100 are avoided.

[0029] In the anti-lining non-reinforced structure mahjong machine bottom plate, the reinforcing plate 200 is arranged on the supporting part 120 of the bottom plate body 100, and the set of stretching grooves 210 which are recessed to the side of the supporting part 120 and are used to improve the structural strength of the reinforcing plate 200 are arranged on the reinforcing plate 200. The reinforcing plate 200 does not have large gaps, and the bending deformation resistance of the bottom plate body 100 is improved without other materials to fill the gaps, and the appearance of the anti-lining non-reinforced structure mahjong machine bottom plate is improved.

[0030] As Figures 1 to 6As shown in the drawings, in an embodiment, the bottom plate body 100 further comprises a first flange 130 arranged at one end of the support portion 120 away from the avoiding portion 110 and bent towards the side of the reinforcing plate 200; the reinforcing plate 200 abuts on the first flange 130. Understandably, the reinforcing plate 200 abuts on the first flange 130, thereby achieving accurate positioning between the bottom plate body 100 and the reinforcing plate 200. The first flange 130 can be arranged perpendicularly to the support portion 120, or can be arranged at different angles with the support portion 120 according to actual conditions, for example, corresponding to the edge of the reinforcing plate 200, as long as the reinforcing plate 200 can abut on the first flange 130, thereby achieving accurate positioning between the bottom plate body 100 and the reinforcing plate 200. The width of the first flange 130 can be arranged according to actual conditions, for example, less than or equal to the depth of the stretching groove group 210, so that the bottom of the stretching groove group 210 can abut on the support portion 120.

[0031] In the embodiment, by arranging the first flange 130 on the support portion 120, accurate positioning is achieved between the bottom plate body 100 and the reinforcing plate 200.

[0032] As shown in the drawings, Figure 7 As shown in the drawings, in an embodiment, the first flange 130 comprises a first bent portion 131 connected at one end of the support portion 120 away from the avoiding portion 110 and bent towards the reinforcing plate 200, a second bent portion 132 connected at one end of the first bent portion 131 away from the support portion 120 and bent towards the avoiding portion 110, and a third bent portion 133 connected at one end of the second bent portion 132 away from the first bent portion and bent towards the support portion 120; the reinforcing plate 200 abuts on the third bent portion 133. Understandably, the reinforcing plate 200 abuts on the third bent portion 133, and forms a tubular structure together with the first bent portion 131, the second bent portion 132 and the third bent portion 133, thereby strengthening the strength and stability of the structure of the first flange 130. The first bent portion 131 can be arranged perpendicularly to the support portion 120, or can be arranged at different angles with the support portion 120 according to actual conditions; the second bent portion 132 can be arranged perpendicularly to the first bent portion 131, or can be arranged at different angles with the first bent portion 131 according to actual conditions; the third bent portion 133 can be arranged perpendicularly to the second bent portion 132, or can be arranged at different angles with the second bent portion 132 according to actual conditions; as long as the reinforcing plate 200 abuts on the third bent portion 133, and forms a tubular structure together with the first bent portion 131, the second bent portion 132 and the third bent portion 133.

[0033] like Figures 1 to 6 As shown, in one embodiment, the edge of the reinforcing plate 200 is provided with a second flange 220 bent toward the support portion 120; the second flange 220 abuts against the first flange 130. It can be understood that the width of the second flange 220 can be set according to actual conditions, for example, equal to the width of the first flange 130, thereby jointly reinforcing the structural strength of the side with the first flange 130; or less than or equal to the depth of the tension groove group 210, so that the bottom of the tension groove group 210 can abut against the support portion 120.

[0034] like Figures 1 to 4 As shown, in one embodiment, the reinforcing plate 200 includes a plurality of trapezoidal plates 230 uniformly arranged on the support portion 120 and abutting against each other; the tension groove group 210 includes a plurality of first outer peripheral grooves 231 disposed on the outer periphery of the trapezoidal plates 230, and a plurality of first central grooves 232 disposed in the middle of the trapezoidal plates 230. It can be understood that the number of trapezoidal plates 230 can be four, and they are identical in shape. The hypotenuses of the four trapezoidal plates 230 abut against each other, the long sides of the four trapezoidal plates 230 abut against the first flange 130, and the short sides of the four trapezoidal plates 230 surround the clearance portion 110, thereby eliminating large gaps on the reinforcing plate 200. This improves the bending deformation resistance of the base plate body 100 without requiring other materials to fill the gaps, thus enhancing the aesthetics of the unreinforced mahjong machine base plate. The connection method between two adjacent trapezoidal plates 230 includes, but is not limited to, one or more of the following methods: welding, screwing, or snap-fitting, as long as it can ensure a stable connection between the two adjacent trapezoidal plates 230. Chamfers can be provided at the four corners of the trapezoidal plates 230 to prevent weld scars from protruding when multiple trapezoidal plates 230 are connected by welding. The depth and shape of the first central groove 232 and the first outer peripheral groove 231 can be set according to actual conditions, as long as they can improve the structural strength of the trapezoidal plates 230 and thus meet the bending deformation resistance requirements of the base plate body 100.

[0035] like Figures 1 to 4 As shown, in one embodiment, the depth of the first central groove 232 is greater than the depth of the first peripheral groove 231.

[0036] like Figures 1 to 2As shown in the drawings, in an embodiment, the bottom surface of at least one of the first outer circumferential grooves 231 is in the shape of a T; and at least two of the first middle grooves 232 are perpendicular to each other. It can be understood that the first outer circumferential grooves 231 and the first middle grooves 232 can each include multiple grooves, so as to avoid the length or width of a single groove being too large, thereby affecting the anti-twist strength. If at least two of the first middle grooves 232 are perpendicular to each other, one of the first middle grooves 232 can be transversely arranged at the middle of the ladder-shaped plate member 230, and therefore, the bottom surface of the first outer circumferential groove 231 arranged at the long side of the ladder-shaped plate member 230 can be in the shape of a T, so as to avoid interference with the first middle grooves 232.

[0037] As shown in the drawings, Figures 3 to 4 As shown in the drawings, in an embodiment, the bottom surface of at least one of the first outer circumferential grooves 231 is in the shape of a T; and at least two of the first middle grooves 232 are perpendicular to each other. It can be understood that the first outer circumferential grooves 231 and the first middle grooves 232 can each include multiple grooves, so as to avoid the length or width of a single groove being too large, thereby affecting the anti-twist strength. If at least two of the first middle grooves 232 are perpendicular to each other, one of the first middle grooves 232 can be transversely arranged at the middle of the ladder-shaped plate member 230, and therefore, the bottom surface of the first outer circumferential groove 231 arranged at the long side of the ladder-shaped plate member 230 can be in the shape of a T, so as to avoid interference with the first middle grooves 232.

[0038] As shown in the drawings, Figures 5 to 6As shown, in an embodiment, the reinforcing plate 200 comprises a plurality of square plate members 240 evenly arranged on the support portion 120 and abutting each other; the stretching groove set 210 comprises a plurality of second outer circumferential grooves 241 arranged on the outer circumferences of the square plate members 240, and a plurality of second middle grooves 242 arranged in the middle portions of the square plate members 240. It can be understood that the number of the square plate members 240 can be four, and the square plate members 240 are identical in shape. The short sides and the long sides of the four square plate members 240 abut each other, the long sides of the four square plate members 240 abut the first flange 130, and the remaining portions of the long sides of the four square plate members 240 abutting the short sides surround the four sides of the avoiding portion 110, so that there is no large gap on the reinforcing plate 200, and the anti-bending deformation strength of the bottom plate body 100 is improved without the need for other materials to fill the gap, and the appearance of the mahjong machine bottom plate with no reinforcing structure is improved. The connection mode between the two adjacent square plate members 240 includes but is not limited to one or more of welding, screwing, or clamping, as long as the two adjacent square plate members 240 can be stably connected. The square plate members 240 can be chamfered at the corners, so that when the connection mode of the plurality of square plate members 240 is welding, the welding scars will not protrude. The depth and shape of the second middle groove 242 can be set according to actual conditions, and the depth and shape of the second outer circumferential groove 241 can also be set according to actual conditions, as long as the structural strength of the square plate member 240 can be improved, and the anti-bending deformation strength requirement of the bottom plate body 100 can be met.

[0039] As Figures 5 to 6As shown, in an embodiment, the depth of the second middle groove 242 is greater than the depth of the second peripheral groove 241. In an embodiment, the bottom surface of at least one of the second peripheral grooves 241 is in the shape of an I-beam; and at least two of the second middle grooves 242 are parallel to each other. Understandably, the second peripheral grooves 241 and the second middle grooves 242 can each include multiple grooves, so as to avoid the length or width of a single groove being too large, thereby affecting the torsional strength. At least two of the second middle grooves 242 can be arranged in parallel and spaced apart in the length direction of the square plate member 240, and therefore, the two second peripheral grooves 241 arranged opposite to the long side of the square plate member 240 can pass through the square plate member 240 in a direction substantially parallel to the second middle grooves 242, thereby forming an I-beam without interfering with the second middle grooves 242. The shapes of the remaining second middle grooves 242 can be arranged according to actual conditions, as long as the structural strength of the square plate member 240 can be improved, thereby meeting the requirements of the bending deformation resistance of the bottom plate body 100. In this embodiment, through the above arrangement, the bending deformation resistance of the bottom plate body 100 is improved without the need for other materials to fill the gaps, thereby improving the aesthetics of the contrast non-reinforced structure mahjong machine bottom plate.

[0040] The above is only an embodiment of the contrast non-reinforced structure mahjong machine bottom plate of the present application, and is not intended to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principles of the present application shall be included in the protection scope of the present application.
