A turning plate is softly pushed by means of acting the turnover cam via the rollers on the rocker arm without causing vibration in a progressive manner, the mahjong pieces are fine in stability, simultaneously, the mahjong pieces can be turned without forward and reverse rotation relative to the corresponding rotating shafts, a motor is simple in control and low in cost, a rotating part on the motor is not easy to be loosened, and working reliability is higher.

Description

A kind of switching mechanism

Technical field

The utility model relates to the mahjong machine in the amusement equipment, and the switching mechanism that relates in particular in the mahjong machine push lifting device is a kind of.

Background technology

200920042089.2), and authorized applicant of the present utility model is called a kind of patent application with switching mechanism of automatic dealing function mahjong machine (patent No.: having proposed name before.The structure of this switching mechanism such as Figure 13, shown in Figure 14, it is made up of turnover panel 141 and clutch unit.One side of turnover panel 141 is connected through the hinge on the license bearing groove face of card storage groove 110, and turnover panel can rotate around hinged side.Clutch unit is made up of push rod 142, rotor plate 143 and driving lever 144.Push rod 142 be bending and bending place and rotor plate 143 with rotating shaft be hinged on the bearing 145 of turnover panel downside, the width L1 of rotor plate 143 is greater than the width L2 of push rod 142, a bending end of push rod 142 is against the downside of turnover panel 141.One end of driving lever 144 is connected in the rotating shaft 38 that transmission mahjong machine card bearing board 120 moves up and down, and the other end can touch the part that rotor plate 143 is wider than push rod 142, promotes rotor plate 143 when touching and rotates.When rotor plate 143 when rotating near push rod 142 directions, drive push rod 142 and rotate, turnover panel 141 is pushed thereupon and rotates, and sees also Figure 15, makes the mah-jong pieces that place on the turnover panel 141 produce upset.When rotating shaft 138 moved up and down by rocking arm 137a drive card bearing board, rotor plate 143 backward rotation were promptly when rotating away from push rod 142 directions, when push rod 142 can not be moved up and down by drive card bearing board 120, remain on the origin-location and do not rotate, turnover panel 141 does not also rotate, and sees also Figure 16.

Above-mentioned switching mechanism utilizes push rod 142 to push effect, promotes turnover panel 141, and this to push action be explosion type when initial, has impact, and the vibration that causes thus can make the board of setting topple over, and the stability of board is affected.In addition, because rotary movement is to utilize the backward rotation that raises motor to promote, so will carry out rotating control to motor, control cost and improve relatively, owing to motor rotating repeatedly, the securing member on it is loosening easily simultaneously, thereby the functional reliability of mechanism is reduced.

Summary of the invention

The purpose of this utility model is to overcome the defective of above-mentioned switching mechanism, and a kind of soft switching mechanism that moves is provided, and above-mentioned purpose is achieved by following technical proposals:

Described switching mechanism, place mahjong machine push lifting device, comprise that one is installed in rotation on the plate reservoir board in the card storage groove, place the turning cylinder of card storage groove downside, comprise that also upset cam and end are equipped with the rocking arm of roller; rocking arm is installed on the described turning cylinder and with turning cylinder and rotated; the upset cam is fixed on described plate reservoir board downside; when rocking arm turns to a corresponding position with turning cylinder; the roller of rocking arm end touches the cam surface on the upset cam; and move along this cam surface, promote upwards rotation of plate reservoir board by the upset cam, the board of plate reservoir board is flipped an angle.

The cam surface of described upset cam is distributed on the end face of curved surface circular arc cylinder, and described end face is the salient point of this cam with its symmetrical centre.

Described cam surface is to the center of curvature direction tilt alpha angle of described curved surface circular arc cylinder.

One other end face of the curved surface cylinder of described upset cam is provided with installed surface, and the upset cam is fixedly connected on the downside of plate reservoir board by this installed surface.

Described installed surface is arranged on negative camber one side of the curved surface cylinder of upset cam.

The medial surface of the curved surface cylinder of described upset cam is provided with triangle and circular arc reinforcement, and the vertical mutually handing-over of these two kinds of reinforcements.

Switching mechanism of the present utility model utilizes the cam surface effect of rocking arm upper roller to the upset cam, promote turnover panel, because being the low side by cam surface, roller enters, and roll to the high-end position of cam surface gradually, impetus is gradual, so showdown action is very soft, not vibration, what the board on the card bearing board can hold mode is stable.Simultaneously, rotary movement of the present utility model does not need the corresponding forward and reverse rotation of turning cylinder, has only the rotation of a direction, and the control of motor is simple, and cost is low.Because motor does not have the rotation of both forward and reverse directions repeatedly, tumbler is difficult for becoming flexible on it, and functional reliability is higher relatively.
