Description

Automatic collapsible type mahjong machine

Technical field

The utility model relates to the mahjong machine, particularly a kind of automatic collapsible type mahjong machine.Mainly be applicable to family, chess and card room etc.

Background technology

Mahjong machine in the market, great majority are not collapsible, even if the mahjong machine that has minority to fold all is manually to finish.As the patent No. is that 200420022723.3 Chinese utility model patent discloses a kind of " folding mahjong machine ", these mahjong facility have main frame, power supply box, footing, universal wheel, power supply box is positioned at the bottom of main frame, four universal wheels are contained in the bottom of footing, its design feature is that main frame is rotating the connection with footing, one side on main frame bottom and footing top is equipped with rotating pin, and opposite side is provided with spring holder.The advantage of this mahjong machine is little, convenient carrying of volume after folding and storage, is specially adapted to less family of area and chess and card room.But the deficiency that exists is must armrest moving folding, because mahjong machine fuselage is heavier, and artificial folding have certain degree of difficulty and danger.

The utility model content

Problem to be solved in the utility model is: provide a kind of easy to operate, security good, convenient carrying and the automatic collapsible type mahjong machine that stores.

The technical solution adopted in the utility model: automatic collapsible type mahjong machine, have main frame and the electric cabinet that is connected with main frame, the footing upper end of supporting as the mahjong machine is connected with main frame, the footing lower end is connected with pedestal, base bottom is equipped with and is used to the universal wheel that supports and move, it is characterized in that the inclined to one side side place of main frame bottom centre is connected by bearing pin is rotating with a side of footing upper end, folding driving mechanism is equipped with in footing inside, and the output of this driving mechanism is connected with main frame bottom centre inclined to one side opposite side place.

Described folding driving mechanism comprises the support that fuses, but the motor that rotating is housed bottom of support, on the output shaft of motor pinion is housed, pinion is meshed with the gear wheel on both sides, and the axle center of gear wheel is fastenedly connected screw mandrel, threaded engagement slide block on the screw mandrel, a fastening pull bar above the slide block, the upper end of pull bar connects the draw back plate of U-shaped and the bearing on both sides by axle A, and this bearing is limited in the slide rail of support inboard slidably, and described draw back plate draws button by axle B connection; Upper and lower side corresponding to screw mandrel is installed limit switch and lower position switch on described support.

The beneficial effects of the utility model are: because these mahjong facility have auto-folder function, the user only needs to push the button and just can finish jackknife action, so operation is very easy, also is difficult for taking place security incident, mahjong body after folding is long-pending to be dwindled, and can carry easily and store.

The specific embodiment

As Fig. 1, Fig. 2, shown in Figure 3, present embodiment has main frame 1 and the electric cabinet 2 of fixedlying connected with main frame, vertical footing 4 upper ends of supporting as the mahjong machine are connected with main frame, the bottom of this footing is a foursquare pedestal, on four angles of pedestal universal wheel 5 is housed all, these routine characteristics are: in a side of the inclined to one side side place of main frame 1 bottom centre and footing 4 upper ends by 3 rotating connections of bearing pin, folding driving mechanism is equipped with in footing 4 inside, and the output of this mechanism is connected with main frame bottom centre inclined to one side opposite side place.

Described folding driving mechanism comprises the support 9 that fuses with screw, but the motor that rotating is housed bottom 8 of support, pinion 10 is housed on the output shaft of motor, pinion is meshed with the gear wheel 11 on both sides, the axle center of gear wheel is fastenedly connected screw mandrel 13, threaded engagement slide block 12 on the screw mandrel, a fastening pull bar 14 above the slide block, the upper end of pull bar flexibly connects the draw back plate 7 of U-shaped and the bearing 15 on both sides by axle A (6), this bearing is limited in the slide rail 17 of support inboard slidably, be that bearing 15 can slide along slide rail 17, described draw back plate 7 flexibly connects by axle B (18) and draws button 19.Upper and lower side corresponding to screw mandrel 13 is installed limit switch 20-1 and lower position switch 20-2 on described support 9.On the end face that draws button 19, can be connected with main frame 1 by bolt, or the welding of the bottom of direct and main frame.

Operation principle of the present utility model is: when the needs main frame is folding, press the folding button that is installed on the main frame 1, control by circuit board, motor 8 forward rotation, driving gear wheel 11 by pinion 10 rotates, gear wheel drives screw mandrel 13 and rotates, screw mandrel drives slide block 12 and moves up, slide block drives pull bar 14 and moves up, the bearing that is contained in the axle A drive both sides of its upper end on pull bar in the process of moving scrolls up along slide rail 17, and the draw back plate 7 that at this moment is enclosed within equally on the bearing A also rotates thereupon, and rotate to the oblique upper of opening to main frame the upper end of draw back plate, because draw back plate 7 is connected with drawing button 19 hinging manners, and draw button to fixedly connected with the main frame bottom, thus finally make main frame folding to a side, when slide block is met limit switch 20-1, motor stops operating, and Host Status as shown in Figure 2.

When the needs main frame launches, press the expansion button that is installed on the main frame, by the control of circuit board, motor 8 backward rotation are by parts such as screw mandrels, the backward rotation of motor 8 is converted to moving downward of slide block 12, by the interlock of pull bar 14 with draw back plate 7, the pulling main frame rotates around axle 3 again, when slide block 12 was met limit switch 20-2 downwards, Host Status as shown in Figure 1.

When main frame folded into any one angle, if outage suddenly, Host Status remained unchanged, because the self-locking performance by screw mandrel, had guaranteed that main frame can be stabilized in any angle in folding.Because of the fuselage heaviness, fold or generally be controlled between 10 seconds to 40 seconds resetting time.
