A kind of middle core apparatus without electronic box mahjong machine
Technical field
The present invention relates to a kind of mahjong machine accessory, in particular a kind of middle core apparatus without electronic box mahjong machine.
Background technology
Existing automatic mahjong machine dice disk center elevating mechanism, adopt thinner center fall way and dice dish to be fixed together, lower end drives center fall way to rise or decline along external guide rail by rocking arm, it is more complicated that this structure also exists structure, adjustable height is restricted, the distance that dice dish rises is short, it is less that desktop throws board opening, especially use during larger mah-jong pieces and affect throwing board, and can shake be produced, the problems such as stuck phenomenon, and an electronic box must be set in addition below automatic mahjong machine iron plate to protect this mechanism, cause and protrude an electronic box below automatic mahjong machine, purchase cost is caused to increase, assembling recruitment increases, exterior and interior packing, cost of warehousing transportation increases.External guide rail rocker-arm central elevating mechanism, center lifting distance limits by rocking arm length, dice dish rises that to throw board opening apart from short, desktop less, especially using during larger mah-jong pieces affects toward mahjong machine inside throwing board, lifting distance is difficult to regulate, and rocking arm is that the center of circle rotates with axle, from low side to high-end; crank centerline does not reach consistent with center fall way center line all the time, so there will be center fall way and dice dish to shake phenomenons such as even blocking.
The usual structure of elevating mechanism of other some mahjong machine dice dishes is comparatively complicated, and cost is also higher.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of middle core apparatus without electronic box mahjong machine, realize steady transmission.
The present invention is achieved by the following technical solutions, the present invention includes driving mechanism, elevating mechanism, position-limit mechanism and dice base; Described elevating mechanism comprises elevator, described elevator is provided with the tubular structure for holding dice base, the tubular structure of described elevator offers lifting apertures along top to bottom, described position-limit mechanism is fixed on the sidewall of dice base, described position-limit mechanism is offered the limiting section for limiting elevator moving direction, described driving mechanism drives elevating mechanism.
The both sides of described lifting apertures are helical form along the top-to-bottom of elevator.Spiral helicine lifting apertures can realize the steady of transmission.
The top of described elevator is horizontal structure.The top of horizontal structure, can realize can effective location in the highest order of lifting.
Described middle core apparatus also comprises Flexible Connector, and connecting hole is offered in the bottom of described elevator, and one end of described Flexible Connector is connected to dice base, and the other end passes the bottom connecting hole of elevator and is fixed in the frame of mahjong machine.Flexible Connector when drive motors drives whole elevator to rotate, can ensure there are enough tractions to dice base.
As one of preferred embodiment of the present invention, described Flexible Connector is elastoplast rope, the built-in connection electric wire of described elastoplast rope.Connect electric wire to power to the dice on dice base.
Described position-limit mechanism comprises the first connector, the second connector and connecting rod, described first connector is fixed on the sidewall of dice base, one end of connecting rod connects the first connector, the other end connects the second connector, and described first connector, the second connector and connecting rod are configured for the I-shaped structure limiting elevator movement.
Described driving mechanism comprises drive motors and driven wheel, and the bottom of described elevator is fixed on described driven wheel, and the output shaft of described drive motors is meshed with described driven wheel by travelling gear.
The present invention has the following advantages compared to existing technology: structure of the present invention is simply easy to use, can realize driving the lifting of dice base by spiral helicine elevator, more efficientlyly can simplify space, guarantee the stability of transmission.

Detailed description of the invention
Elaborate to embodiments of the invention below, the present embodiment is implemented under premised on technical solution of the present invention, give detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
As shown in FIG. 1 to 3, the middle core apparatus of the present embodiment comprises driving mechanism 1, elevating mechanism 2, position-limit mechanism 3, dice base 4, Flexible Connector 5; Described elevating mechanism 2 comprises elevator 21, described elevator 21 is provided with the tubular structure for holding dice base 4, the tubular structure of described elevator 21 offers lifting apertures 22 along top to bottom, described position-limit mechanism 3 is fixed on the sidewall of dice base 4, described position-limit mechanism 3 is offered the limiting section for limiting elevator 21 moving direction, described driving mechanism 1 drives elevating mechanism 2.Connecting hole is offered in the bottom of described elevator 21, and one end of described Flexible Connector 5 is connected to dice base 4, and the other end passes the bottom connecting hole of elevator 21 and is fixed in the frame of mahjong machine.Flexible Connector 5 when drive motors drives whole elevator 21 to rotate, can ensure there are enough tractions to dice base 4.
The both sides of described lifting apertures 22 are helical form along the top-to-bottom of elevator 21.Spiral helicine lifting apertures 22 can realize the steady of transmission.
The top of described elevator 21 is horizontal structure.The top of horizontal structure, can realize can effective location in the highest order of lifting.
The Flexible Connector 5 of the present embodiment is elastoplast rope.Also the connecting line of similar telephone and receiver can be selected in other embodiments as Flexible Connector 5.
As shown in Figure 4, described position-limit mechanism 3 comprises the first connector 31, second connector 32 and connecting rod 33, described first connector 31 is fixed on the sidewall of dice base 4, one end of connecting rod 33 connects the first connector 31, the other end connects the second connector 32, and described first connector 31, second connector 32 and connecting rod 33 are configured for the I-shaped structure limiting elevator 21 movement.
Described driving mechanism 1 comprises drive motors (not shown) and driven wheel 11, and the bottom of described elevator 21 is fixed on described driven wheel 11, and the output shaft of described drive motors is meshed with described driven wheel 11 by travelling gear.
During the present embodiment work, as shown in Figure 1, dice base 4 declines and is fastened in elevator 21 completely, drive motors drives driven wheel 11 to rotate, elevator 21 rotates, by on the lifting apertures 22 from elevator 21 side, prop up position-limit mechanism 3, thus drive dice base 4 centrally line rising, and when on the top water flat structure that position-limit mechanism 3 is positioned at elevator 21, dice base 4 is located, after throwing dice, drive motors continues to drive, driven wheel 11 is made to continue to rotate, thus drive elevator 21 to rotate, position-limit mechanism 3 slides to the lifting apertures 22 of elevator 21 opposite side by the horizontal structure at elevator 21 top, and slide to the bottom of elevator 21, drive dice base 4 to enter in the tubular structure of elevator 21 simultaneously, realize the landing of dice base 4.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
