Description
Technical field
The utility model relates to a kind of amusement equipment, more particularly, relates to a kind of automatic mahjong machine desktop and plays a card and raise one-directional rotation controller in the mechanism.
Background technology
The mahjong entertainment is with a long history in China, is subjected to liking of the masses deeply, thereby the automatic mahjong machine of convenient this amusement more and more is widely used at present.Its four side of existing automatic mahjong machine is equipped with desktop and raises the mechanism that plays a card, and during work, the desktop of four direction raises the mechanism that plays a card and should work asynchronously.As asynchronous, or the mechanism of some directions breaks down, and automatic mahjong machine is with regard to cisco unity malfunction.
The rotation direction that desktop raises motor output shaft in the mechanism that plays a card keeps normal operating conditions to cause closing important to automatic mahjong machine, in case counter-rotating appears in motor, the mutual movement relation that mechanism Central Plains is set is destroyed, the relative position relation of parts changes, will produce movement interference, some parts are damaged.For example: the motor counter-rotating, spring 14 cards that touch on the travel switch are pressed in this breach 19 of travel switch locating wheel 18, see Fig. 2, cause the trip switch to damage; Motor counter-rotating also can rise on the hook that the board small rocker withstands on lifting support one side, might its support is disconnected; In addition, motor counter-rotating makes two pairs of bevel gears raising in the mechanism that plays a card can not the normal engaged transmission, causes bevel gear to damage.
And at present desktop raises that motor in the mechanism that plays a card adopts substantially is the reversible synchronous motor of deceleration permanent magnetism, have 8 rotors to (S, N) utmost point ferrite permanent-magnet materials, this rotor is subject to factor affecting such as environment temperature, work temperature rise, capacitance variation, input voltage variation and demagnetization takes place, 8 extreme difference occurs to (S, N) interpolar, causing that electric motor starting turns to instability, output torque to reduce or is subjected to working resistance counter-rotating will occur, cause above-mentioned damage of components, influence the operate as normal of automatic mahjong machine.
Summary of the invention
The purpose of this utility model is exactly at above-mentioned the deficiencies in the prior art, designs a kind of automatic mahjong machine desktop that prevents that motor from rotating and plays a card and raise one-directional rotation controller in the mechanism, and it is realized by following technical scheme:
Be installed on the motor output shaft of described mechanism, comprising shell, interior lining ring, unidirectional rotating disk and rolling element, lining ring is connected the shell inboard in described, unidirectional rotating disk is connected on the described motor output shaft and places in the interior lining ring, can relative in lining ring and shell rotate, rolling element places the groove of unidirectional rotating disk week side.
All sides of described unidirectional rotating disk are provided with some groove depths along a groove that circumferentially shrinks gradually.
Described shell inboard is provided with circumferential retention tab; Lining ring is provided with corresponding circumferential locking groove in described, and described circumferential retention tab interlocking makes shell not rotate relative to having with interior lining ring in described circumferential locking groove.
Described rolling element is roller or ball.
The beneficial effects of the utility model are: 1) can prevent motor counter-rotating effectively, thus the movement interference of stopping to cause thus and make the phenomenon of part sustain damage in the mechanism; 2) structure dexterity can be installed on the output shaft of motor easily, does not influence the overall structure of mechanism; 3) simple in structure, component part is few, and is easy to make, and cost is low.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment.
Fig. 2 is that prior art medium power output shaft counter-rotating travel switch locating wheel and travel switch touch the schematic diagram that spring moves interference
Among the figure, the 1st, shell, the 2nd, unidirectional rotating disk, the 3rd, interior lining ring, the 4th, roller, the 6th, groove, the 7th, the hole, the 14th, touch spring, the 18th, travel switch locating wheel, the 19th, the breach on the travel switch locating wheel.
The specific embodiment
Below in conjunction with drawings and Examples the utility model and advantage thereof are described further.
Please contrast Fig. 1, the one-directional rotation controller that the automatic mahjong machine desktop of present embodiment raises in the mechanism that plays a card is made up of shell 1, interior lining ring 3, unidirectional rotating disk 2 and roller 4.Interior lining ring 3 is connected in shell 1 corresponding inboard aperture, and all sides of the inboard aperture of shell 11 and interior lining ring 3 are provided with corresponding projection 9 and groove 8, and by the cooperation of this projection and groove, lining ring 3 is located in the inboard aperture of shell 11 in making, and rotates relative to not having.In the lining ring 3, it circumferentially had certain interval with interior lining ring 3 in unidirectional rotating disk placed, and it is 0.35 millimeter that present embodiment is set this gap, make it can relative in lining ring 3 and shell 11 rotate.The center of unidirectional rotating disk 2 is provided with the hole 7 that is connected with motor output shaft in the mechanism that plays a card, and is connected with motor output shaft and rotation thereupon by this hole.All sides at it are evenly equipped with the groove 6 that four groove depths are shunk gradually along a circumferential direction, are equipped with a roller 4 in each groove 6.The depth capacity of groove 6 is slightly larger than the diameter of roller 4.The depth capacity of groove 6 is Duoed 0.15 millimeter than the diameter of roller 4 in the present embodiment.In the present embodiment, its shell 11 adopts transparent material, makes this steering controller outward appearance more elegant in appearance.
Motor forward (counterclockwise) rotates during work, unidirectional rotating disk 2 rotates (solid arrow indication rotation direction among Fig. 1) thereupon in the same way, roller 4 is made circular motion under the effect of interior lining ring 3, and tangentially increases the direction motion to groove 6 degree of depth, and it is against on the cell wall of groove 6 the widest part.Because the width of cell wall is greater than the diameter of roller 4, so when unidirectional rotating disk 2 rotated, the roller 4 between interior lining ring 3 and unidirectional rotating disk 2 can not block the motion that unidirectional rotating disk 2 influences unidirectional rotating disk 2.Be subjected to working resistance and counter-rotating can occur when electric motor starting instability or output torque reduce, the same reason, roller 4 is made circular motion under the effect of interior lining ring 3, and tangentially reduce direction motion (dotted arrow indication rotation direction among Fig. 1) to groove 6 degree of depth, when roller 4 moves to its diameter greater than this place groove depth, between lining ring 3 and the unidirectional rotating disk 2, unidirectional rotating disk 2 can not be rotated in roller 4 will be stuck in, raise that motor can only be to the control action of direction rotation in the mechanism that plays a card thereby play to make.
This one-directional rotation control structure can be simply effectively and control the backward rotation of motor output shaft in time, thereby stop the damage of components phenomenon that causes by movement interference.The simple volume of this controller architecture is little simultaneously, can be installed in desktop easily and raise in the mechanism that plays a card, and does not influence the overall structure of mechanism.
