Abstract
The utility model relates to an automatic mahjong table, particularly an automatic mahjong table with low noise, which solves the disadvantage that the noise of the present automatic mahjong table is larger. The automatic mahjong table with low noise comprises a base and an outer frame of the mahjong table; the outer frame of the mahjong table is positioned on the base, the upper surface of the outer frame of the mahjong table is provided with a table surface plate, and a shuffle warehouse the bottom surface of which is provided with a big rotating disk is arranged in the cavity body of the outer frame of the mahjong table. The utility model has the improvement that a square sound absorption and sound insulation plate is added above the shuffle warehouse; the sound absorption and sound insulation plate is a composite plate which has a three layer composite structure, the middle layer is provided with a thin steel plate, and the upper layer and the lower layer are provided with both sound absorption cotton; the thickness of the sound absorption cotton at the lower layer is larger than the thickness of the sound absorption cotton at the upper layer, the thickness of the sound absorption cotton at the lower layer is three to seven mm, and the thickness of the sound absorption cotton at the upper layer is eight to sixteen mm; the middle of the sound absorption and sound insulation plate is provided with a circular hole which is formed by splicing two completely identical parts; the structural parts relevant to the shuffle sounding are all made of polyurethane materials, and the big rotating disk is made of nylon materials. The utility model is used for families or recreation situations, and can reduce noise by six decibels.
Description
Technical field: the utility model relates to a kind of automatic Mah-jongg machine, particularly a kind of low noise automatic Mah-jongg machine.
Background technology: using automatic Mah-jongg machine to carry out amusement has become a kind of leisure fashion, though use automatic Mah-jongg machine to bring to save many benefits such as reason board, make amusement more easily, more comfortable.Chinese patent ZL01253868.x has introduced a kind of " automatic Mah-jongg machine ", though very easy to use, the sound that sends during the resonable board of automatic Mah-jongg machine goes even farther than manual reason board, becomes its unique shortcoming.How reducing the influence of reason board noise on human as far as possible, is the target that we research staff pursues.
Summary of the invention: the utility model technical issues that need to address are: under the overall dimensions that do not influence automatic Mah-jongg machine, function of use, prerequisite easy to maintenance, and the noise that distributes of environment towards periphery when significantly reducing its reason board.The technical solution of the utility model is: a kind of low noise automatic Mah-jongg machine, comprise base, the mahjong table housing, the mahjong table housing is seated on the base, be provided with deck plate at mahjong table housing upper surface, in mahjong table housing cavity, be mounted with the storehouse of shuffling, the bottom surface, storehouse of shuffling is a traffic cycle, its improvement is: increase a foursquare sound-absorbing, resistant panels above the storehouse of shuffling, this sound-absorbing, resistant panels is a composite plate, be 3 layers of composite construction, middle one deck is a sheet metal, and the upper and lower are acoustical cotton, and the thickness of lower floor's acoustical cotton is greater than the thickness of upper strata acoustical cotton, lower floor's acoustical cotton thickness is 3-7mm, upper strata acoustical cotton thickness is 8-16mm, in the middle of the sound-absorbing, resistant panels circular hole is arranged, and is spliced by 2 identical parts.The structural member relevant with the sounding of shuffling all adopts polyurethane material, and traffic cycle adopts nylon material.The beneficial effects of the utility model are: owing to increased sound-absorbing, resistant panels, the sound that sends in the time of can reducing automatic Mah-jongg machine reason board greatly, and because the structural member relevant with the sounding of shuffling all adopts polyurethane material, traffic cycle adopts nylon material, it is lower that polyurethane can satisfy under the prerequisite of rigidity its hardness, and the strike note that itself and mahjong produce is also lower.Nylon then is a kind of absorbing and the good material of sound absorbing capabilities.By adopting above-mentioned three measures, can be so that the noise of automatic Mah-jongg machine descends about 6 decibels.
Description of drawings:
Fig. 1 is the utility model structural representation
Fig. 2 is the sound-absorbing, resistant panels structural representation
Among the figure: 1-base, 2-mahjong table housing, 3-deck plate, the 4-storehouse of shuffling, 5-sound-absorbing, resistant panels, 5-1-upper strata acoustical cotton, 5-2-steel plate, 5-3-lower floor acoustical cotton, 6-traffic cycle.
The specific embodiment: with reference to Fig. 1,2, a kind of low noise automatic Mah-jongg machine, comprise base 1, mahjong table housing 2, mahjong table housing 2 is seated on the base 1, be provided with deck plate 3 at mahjong table housing 2 upper surfaces, in mahjong table housing 2 cavitys, be mounted with the storehouse 4 of shuffling, 4 bottom surfaces, storehouse of shuffling are traffic cycle 6, above the storehouse 4 of shuffling, increase a foursquare sound-absorbing, resistant panels 5, this sound-absorbing, resistant panels 5 is a composite plate, be 3 layers of composite construction, middle one deck is sheet metal 5-2, and the upper and lower are acoustical cotton, the thickness of the acoustical cotton 5-1 of lower floor is 5mm, the thickness of upper strata acoustical cotton 5-3 is 12mm, in the middle of the sound-absorbing, resistant panels 5 circular hole is arranged, and is spliced by 2 identical parts.Structural member relevant with the sounding of shuffling such as mahjong table housing and the storehouse of shuffling all adopt polyurethane material to make, and traffic cycle 6 adopts nylon material to make.
