Therefore, the above terms should not be understood as limiting the present invention.

[0053] Example

[0054] like Figures 2 to 19 As shown, the present embodiment provides a modular mahjong machine host, which adopts a modular design concept and improves the traditional bottom plate into a modular base. At the same time, the modular structure of the conveying assembly module, the head assembly module, the mesh assembly module, and the aluminum bar assembly module are matched, and the modular base is provided with corresponding mounting parts. Each module is installed on the modular base by plugging it into the mounting part. Compared with the traditional assembly method of the mahjong machine host, the assembly accuracy and efficiency are significantly improved.

[0055] A large plate mechanism is arranged in the middle of the modular base, a card-digging bar is arranged above the large plate mechanism, and a driving mechanism for driving the large plate mechanism and the dice box. When the device is running, the large plate rotates and the card-digging bar stirs the mahjong tiles. In this embodiment, the large plate mechanism, the card-digging bar, the dice box and the driving structure all adopt existing mature structures, and no improvement is made to them. For those skilled in the art, these structures are known, so they will not be described in detail here. The program control system and related circuit modules used to control the operation of the mahjong machine host can also adopt existing mature structures, which do not belong to the improvement points of the present invention. For those skilled in the art, the above structures are also known, so they will not be described in detail.

[0056] The modular base is composed of four base modules with the same structure, each base module is provided with installation parts of the conveying assembly module, the head assembly module, the mesh plate assembly module and the aluminum bar assembly module. Correspondingly, there are four conveying assembly modules, head assembly modules, mesh plate assembly modules and aluminum bar assembly modules. The conveying assembly module, head assembly module, mesh plate assembly module and aluminum bar assembly module on one base module constitute a group, totaling four groups, and each group corresponds to one direction.

[0057] The large disk operation area parts of the four base modules are combined to form a complete circle. The circular space is the complete large disk operation area, and a through hole for installing the intermediate mounting plate is formed in the middle of the circular space. According to the structure of the intermediate mounting plate, the through hole structure matches it. In this embodiment, the through hole adopts a square structure. The square through hole is located in the circular middle part of the large disk operation area, and the two are coaxial. The intermediate mounting plate is installed in the through hole surrounded by the four base modules, and the four sides of the intermediate mounting plate are respectively connected to the mounting holes on the base module.

[0058] 1. Introduction to the base module structure

[0059] The base module adopts a modular design concept, which is equivalent to cutting a square base into four identical module structures. The module structure is the base module. The base module is formed by injection molding, and its upper structure is an integrated structure, which has the advantages of low cost and light weight.

[0060] The base module includes a substrate, which is a rectangular structure with a certain thickness. An assembly connection port is provided at the upper left portion of the substrate. The overall shape of the substrate with the assembly connection port is an "L"-shaped structure. The assembly connection port is a rectangular structure, and its length matches the length of the right side of the substrate, so that the right end of another base module can be embedded in the assembly connection port. The width of the assembly connection portion is not particularly limited, so as to facilitate the assembly and connection of adjacent base modules. When two adjacent base modules are assembled, the right end of one base module is embedded in the assembly connection port of the other base module to achieve assembly and assembly.

[0061] In order to ensure the connection firmness of adjacent base modules, a structure for reinforcing the connection should be provided at the connection between the two, for example, accessories for improving the connection firmness. In the present embodiment, an assembly connection mechanism is used to improve the connection firmness between the two. Specifically, the assembly connection mechanism includes an assembly connection protrusion provided on the right side of the substrate, and an assembly connection groove provided on the substrate and located in the assembly connection port; or, the assembly connection mechanism includes an assembly connection groove provided on the right side of the substrate, and an assembly connection protrusion provided on the substrate and located in the assembly connection port; wherein the assembly connection groove and the assembly connection protrusion match, and preferably, the assembly connection groove is a dovetail groove, and the assembly connection protrusion is a dovetail groove. The following description is based on the arrangement of an assembly connection protrusion on the right side of the substrate and an assembly connection groove in the assembly connection port. Specifically, two assembly connection protrusions are arranged at intervals on the right side of the substrate, and one assembly connection protrusion is arranged on the upper side of the substrate, and the assembly connection protrusion on the upper side is close to the right side of the substrate. At the same time, two assembly connection grooves are arranged at intervals on the substrate located at the lower side in the assembly connection port, and one assembly connection groove is arranged on the substrate located at the right side in the assembly connection port. The distance between the assembly connection protrusions arranged at intervals is equal to the distance between the assembly connection grooves arranged at intervals, and the positions of another assembly connection groove and another assembly connection protrusion match. Through the above arrangement, when assembling two adjacent base modules, the right end of one base module is embedded in the assembly connection port of the other base module, and the assembly connection protrusion at its right end is embedded in the assembly connection groove in the assembly connection port, thereby realizing the assembly connection.

[0062] The front end surface of the substrate is integrated with several structures for installing parts. Specifically, a first protrusion is arranged on the left side of the front end surface of the substrate, and a second protrusion is arranged on the right side thereof. The first protrusion and the second protrusion are both protruding from the substrate. The two protrusions are located on the same straight line at the front end position of the substrate. There is a gap between the two protrusions, and a corresponding groove structure is formed on the substrate. The two are set as a mesh assembly installation part for installing the mesh assembly. The mesh assembly is a push-up structure for pushing cards, and it has a lifting motor. Therefore, at the same time, a lifting motor avoidance part is also arranged on the front end of the mesh assembly installation part on the substrate to provide an installation space for the lifting motor. The mesh assembly adopts a modular structure, and direct positioning and plugging can be achieved during installation. In this embodiment, positioning and installation grooves are arranged on the end surfaces opposite to the first protrusion and the second protrusion. The positioning and installation grooves are through grooves that penetrate the upper and lower end surfaces of the first protrusion and the second protrusion. When installing the mesh assembly, the two ends of the mesh assembly are aligned with the positioning and installation grooves and inserted.

[0063] In this embodiment, a supporting column is further provided at the lower left corner of the base plate. The supporting column is a metal structure and is formed together with the base plate by in-mold injection molding. The supporting column has an "L"-shaped folded plate and wraps around the first protrusion.

[0064] Next, a push-up shaft seat with a socket at the end is provided at the rear ends of the first protrusion and the second protrusion; the height of the push-up shaft seat is lower than the first protrusion and the second protrusion, and the socket thereon is used for plugging and installing two connecting shafts of the aluminum bar assembly, and a lifting plate is provided on the aluminum bar assembly.

[0065] Located at the rear end of the push-up shaft seat is a conveying assembly mounting portion for installing the conveying assembly. Specifically, the conveying assembly mounting portion includes an arc-shaped protrusion arranged on the substrate, and a conveying motor avoidance portion located on the left side of the arc-shaped protrusion. An installation positioning hole or an installation positioning member is arranged on the arc-shaped protrusion (the following description is based on the setting of the installation positioning hole). The height of the arc-shaped protrusion is lower than the push-up shaft seat, and its arc protrudes toward the front end of the substrate. The number of installation positioning holes or installation positioning members is not particularly limited, and can be one, two, three, or even more, so as to facilitate positioning when installing the conveying assembly. The conveying motor avoidance portion is a recessed structure on the left side of the arc-shaped protrusion, which is used to provide an installation space for the conveying motor in the conveying assembly.

[0066] A plate holder mounting portion is provided between the left side of the conveying motor avoidance portion and the left end surface of the base plate for mounting the plate holder; the plate holder mounting portion is a raised structure protruding from the base plate, and its height is close to that of the first raised portion.

[0067] A machine head assembly mounting portion is arranged on the right side of the substrate, at the right end of the second protrusion and the arc-shaped protrusion. The machine head assembly mounting portion is a recessed space lower than the second protrusion, and its bottom is a substrate structure. The assembly connection protrusion arranged on the right side of the substrate is adjacent to the machine head assembly mounting portion.

[0068] The arc-shaped recessed position of the arc-shaped protrusion is located between the rear ends of the substrate to form a large disk operation area portion for the operation of the large disk. The large disk operation area portion is a space lower than the arc-shaped protrusion, and its bottom is a part of the substrate; the large disk operation area portion is a part of the actual large disk operation area. When the four base modules are combined into one, the four large disk operation area portions form a complete circle, that is, a complete large disk operation area portion.

[0069] In this embodiment, a plurality of accessory mounting holes are arranged on the substrate corresponding to the large disk operation area, and other small accessories used for the operation of the equipment are installed through the accessory mounting holes. The structure of the accessory mounting holes matches the required installation accessories, and the setting position and quantity also match the required installation accessories, which are not specifically limited here. The accessories include magnets installed in the magnet mounting holes and rollers installed in the roller mounting holes. The substrate of this part is also provided with mounting holes for the middle mounting plate, and the specific positions are as follows: the side of the substrate located on the right side of the assembly connection port is provided with a mounting hole for installing the middle mounting plate. After the four base modules are combined into one, the middle part is a square through hole, which is used to install the middle mounting plate. The middle mounting plate is used to install the lifting device of the mahjong machine, the large disk bearing and other structures.

[0070] The traditional mahjong machine bottom plate is a flat metal plate. After the relevant components are installed on it, the wiring harness is messy. To address this technical problem, the present embodiment is further provided with a concealed wiring mechanism. Specifically, the concealed wiring mechanism includes a wire card arranged on the base plate, a wiring channel portion arranged on the back end surface of the base plate, and a wire harness hole located on the left side of the conveying motor avoidance portion. The wire card is used to constrain and fix the wire harness, such as Figure 4 The dotted line in the figure is the wiring path of the wiring harness.

[0071] Based on the structural design of the above-mentioned base module, in this embodiment, the conveying assembly, head assembly, aluminum bar assembly, mesh assembly, etc. all adopt structured modules to match the corresponding mounting parts on the base module. The structure of each module is introduced below.

The various components in the conveying assembly module adopt the same structure as the existing conveying structure, except that these components are integrated into an integrated structure through the conveying shell module. At the same time, a mounting locator matching the mounting locating hole is set at the lower end of the conveying shell module. The conveying shell module adopts injection molding, and the number and relative position of the mounting locator match the mounting locating hole on the substrate. Generally, the mounting locator and the mounting locating hole are both three and are arranged at intervals or evenly distributed in the transverse direction. When installing, the mounting locator of the conveying assembly module is aligned with the mounting locating hole and inserted to complete the installation, which is very convenient. It should be known that the setting positions of the mounting locator and the mounting locating hole can be exchanged, that is, the mounting locator is set on the substrate, and the mounting locating hole is set on the conveying assembly module, which can also realize the positioning connection between the two, which is an equivalent replacement for those skilled in the art.
