Description

Lottery machine

The utility model relates to a kind of lottery wheel.

Existing lot cast device has two kinds of mechanical type and full electronics.Full electronic lot cast device is to produce one group of random digit with electronic circuit, and shows that by video screen it is display digit fast, but intuitive and recreational relatively poor; Mechanical type lot cast device intuitive is strong, but exist the slow and use of lot cast speed to owe shortcoming flexibly, such as, the butterfly valve type lottery wheel that Chinese patent application proposes for No. 87211045, this machine comprises a plurality of big hollow balls, place the bead of ten band numerals in each hollow ball, and hollow ball also will be installed special butterfly valve, one-piece construction is very complicated, uses also very dumb.

The purpose of this utility model is that a kind of lottery wheel with lot cast speed faster and simple structure will be provided.

For achieving the above object, the lottery wheel that the utility model proposes comprises electric driver part and stores mechanical component two parts that dish is formed by big hollow ball, digital bead, bead driving lever, bead guide rail and the bead of band, concrete structure is such: on a flat box-like base two vertical support frames are arranged, be equipped with between this support can be on two stands the big hollow ball that rotates of the formed axle of tie point, respectively there is a through hole both sides (holder orientation) of big hollow ball, one of them is the bead hand-hole, and tiltable bead transfer dish also is housed outside this hole; Another portals for bead, the bead position-limiting tube is arranged outside this hole, the bead that a plurality of cups of word order are placed in the position-limiting tube below stores dish, be fixed with the pipe that extends internally on this hole, the bead driving lever is equipped with in the inner of pipe, the cross section is the bead release key of semicircular arc-shaped guide rail and guide rail bottom, the bead driving lever is L shaped, it is dialled bead near the guide rail external port, bead rolls until guide rail the inner from outside to inside along guide rail when rotated, the inner groove that forms with the pipe intersection of guide rail cooperates with the bead release key, make and open release key when only remaining a bead, thereby each only portalling from bead sent a bead, above-mentioned rotation is finished by electric driver part, and electric driver part comprises motor, the frictionally of installing on the motor shaft drives the rubber wheel that big hollow ball rotates, supply unit and just, reverser.During the forward switch connection, big hollow ball just changes, and whenever circles and can send a bead, and when reverser was connected, bead was mixed but do not send in big hollow ball.

From above-mentioned explanation as can be seen, lottery wheel of the present utility model has been concentrated the advantage of existing electronic type and mechanical type lottery wheel, and is not only simple in structure, intuitive is strong, and lot cast speed is fast.

Below in conjunction with embodiment and accompanying drawing thereof the utility model is described further.

Fig. 1 is the skeleton view according to the lottery wheel that the utility model proposes; Fig. 2 is the cut-open view along the C-C line of lottery wheel shown in Figure 1.

As depicted in figs. 1 and 2, this lottery wheel comprises flat box-like base 1, two vertical support frames 2 and 3 about having on the base, big hollow ball 4 is installed between these two supports, and can serve as that (direction shown in the arrow A is a forward among Fig. 1, in the big hollow ball left and right sides (bracket side) through hole 5 and 6 is arranged respectively in the axle rotation with the line of support place on two stands.In the present embodiment, radially install one section pipe additional on the through hole of big hollow ball, the hole on the support is passed in the pipe outer end, thereby realizes the support of big hollow ball and make it to rotate around the strong point.Be provided with bead transfer dish 7 in the outside of through hole 5, it is articulated on the left side brackets 2, so that dress is with digital bead 8 in big hollow ball; Be provided with the bead position-limiting tube 9 of vertical direction in through hole 6 outsides,, store dish 10 and can move (manual), so that bead falls into different cups along the arrow B direction by the user so that bead accurately falls into the cup 11 that bead stores word order on the dish 10.The pipe 12 inside horizontal-extendings of installing on the right side through hole 6 are than the slightly little distance of big hollow ball radius, (from inside to outside) is equipped with bead driving lever 15 successively, the cross section is semicircular guide rail 14 and bead release key 13 in pipe 12 the inners, and they and pipe 12 rotate (when the electric driver part of being described later when big hollow ball drives) with big hollow ball together.Driving lever 15 has four, and each is L-shaped, and wherein the part with radially basic quadrature tilts, so that push bead near guide rail 14 external port and bead is effectively mixed.Guide rail 14 is curved, it is between two driving levers, when big hollow ball when arrow A direction (forward) is rotated, indivedual beads are stirred and are rolled on the semicircle guide rail by driving lever, and be rolled into its inner (this process is followed the rotation of big hollow ball and taken place) gradually from the guide rail outer end, when bead moves on to the junctional area of guide rail 14 and pipe 12, bead can not directly enter in the pipe, because bead release key 13 is not also opened, the bead release key is the foil in the slit that is hinged on the pipe 12, when guide rail 14 the inners roughly are horizontal, release key 13 is owing to action of gravity is opened, and can only have this moment a bead, the unnecessary bead guide rail that all slipped away to fall into big hollow ball bottom on guide rail, that is to say that release key 13 plays a part to stop unnecessary bead to enter pipe 12.The rotation of big hollow ball is driven by electric driver part, this driver part comprises the rubber wheel 21 installed on motor 20, the motor shaft, to electric battery 22, forward switch 23 and the reverser 24 of motor power supply, during the forward switch connection, big hollow ball rotates along arrow A, and the bead of output that whenever circles, when reverser was connected, big hollow ball rotated along the direction opposite with arrow A, do not have bead output this moment, only work the effect that mixes bead.Rubber wheel 21 contacts with big hollow ball bottom, utilizes friction force to order about its rotation.In the present embodiment, big hollow ball 4, pipe 12, position-limiting tube 9, transfer dish 7, cup 11 are made by transparent plastic, make the whole process of bead motion to see too clearly from the outside.
