One side wall of the sliding section 2a is a detachable movable wall, and a maintenance window 2b penetrating through is formed on the sliding section 2a after removing the movable wall.

[0032] During installation, components such as the large plate driving component and the mahjong machine control panel driving component are all arranged in the machine cavity 3. A maintenance window 2b is provided on the sliding section 2a, and the maintenance window 2b is covered by the movable wall. On the premise of not affecting the normal sliding of mahjong tiles, the large plate 2 can be rotated to move the maintenance window 2b to the maintenance position, and maintenance personnel can lean over to repair the electrical components in the machine cavity 3 through the maintenance window 2b, which has the advantages of convenient and easy maintenance.

[0033] Further explanation, the maintenance window 2b is in a fan-shaped structure and is coaxially arranged with the large plate 2, and the upper side and the lower side of the maintenance window 2b are respectively close to the top and the bottom of the sliding section 2a to effectively expand the area of the maintenance window 2b for more convenient maintenance. In the actual product, the area of the maintenance window 2b is close to 1 / 4 of the side wall area of the sliding section 2a.

[0034] Among them,

[0035] The bottom wall of the iron plate 1 is stretched downward to form the above-mentioned concave cavity 1a, so as to reduce the assembly process and facilitate assembly.

[0036] As Figures 3 to 6 shown, the movable wall structure is as follows: The sliding section 2a is composed of a sector plate 2d and a conical main body 2c. Among them, the sector plate 2d is the above-mentioned movable wall. A sector groove 2e matching the sector plate 2d is formed through the side wall of the main body 2c. A sector retaining ring 2f is formed on the inner wall of the sector groove 2e, and the inner hole of the sector retaining ring 2f is the above-mentioned inspection window 2b. The sector plate 2d is detachably fixed in the sector groove 2e, and the sector plate 2d presses on the retaining ring 2f to cover the above-mentioned inspection window 2b. With the above design, it is convenient for the formation of the inspection window 2b and the disassembly and assembly of the movable wall. Further explanation, a sector guide ring 2d1 matching the inspection window 2b is formed on the inner side of the sector plate 2d, and the guide ring 2d1 is inserted into the inspection window 2b. The cooperation between the guide ring 2d1 and the inspection window 2b is used for the installation guidance of the sector plate 2d, which is convenient for the disassembly and assembly of the sector plate 2d, and thus further facilitates the inspection.

[0037] The installation method of the sector plate 2d is as follows: A circle of stepped holes is vertically penetrated on the sector plate 2d, and threaded holes with the same number as the stepped holes are correspondingly formed on the retaining ring 2f. A screw 4 is arranged in each stepped hole, the rod part of the screw 4 is screwed into the corresponding threaded hole, and the head of the screw 4 is located in the corresponding stepped hole. The screw 4 is vertically arranged with the head facing upward, which further facilitates the disassembly and assembly of the sector plate 2d.

[0038] As Figures 1 to 3 shown, the installation method of the large plate 2 is as follows: An annular bearing seat 2c1 is formed on the inner side of the top of the main body 2c, and the bearing seat 2c1 is coaxially arranged with the main body 2c. During installation, a column is vertically fixed on the bottom wall of the concave cavity 1a, and the large plate 2 is rotationally arranged on the iron plate 1 through the bearing seat 2c1 and the bearing, which has the advantages of convenient installation and stable operation. Preferably, the axial section of the bearing seat 2c1 is L-shaped, which is convenient for bearing installation. Further explanation, a circle of rollers is also arranged between the outer edge of the bottom wall of the large plate 2 and the iron plate 1, and the two sides of the outer peripheral surface of the roller are respectively pressed against the large plate 2 and the iron plate 1.

[0039] As Figure 4 shown, an internal gear ring coaxial with the large plate 2 is formed on the inner wall of the sliding section 2a, and the internal gear ring is surrounded by an arc section one 2c2 formed on the inner wall of the main body 2c and an arc section two 2d2 formed on the sector plate 2d. The arc section two 2d2 can not only be used to form the internal gear ring, but also form a function similar to that of a reinforcing rib to effectively strengthen the strength of the sector plate 2d and ensure the stable operation of the large plate 2.

[0040] In the actual product, heat dissipation holes, horn holes and slots for installing power sockets are formed on the bottom wall of the concave cavity 1a. Embodiment Two

[0041] The structure and principle of the second embodiment are basically the same as those of the first embodiment. The difference lies in that the sector plate 2d is clamped in the sector groove 2e, and the detachable installation of the sector plate 2d can also be realized.
