Description

Technical Field

[0001] This utility model relates to the field of entertainment facilities technology, and in particular to an automatic ball dispenser box for lottery machines. Background Technology

[0002] A lottery machine is a device used to randomly select balls or numbers, and is widely used in scenarios such as drawing lots, queuing, and lotteries. Existing roller-type lottery machines typically include a support frame, a rotatable roller, a disturbance mechanism for agitating the balls, and a ball outlet structure. The balls are thoroughly mixed after being rotated and disturbed inside the roller, and then output through an opening or channel on the outside of the roller to complete the lottery process.

[0003] However, existing roller-type lottery machines still have certain shortcomings in ball dispensing control. On the one hand, many machines still require manual removal of balls from the dispensing port, which is inconvenient and inefficient. On the other hand, although some lottery machines are equipped with a bowl-shaped ball dispensing structure, due to insufficient control precision, multiple balls may slip out or leak out during rotation, affecting the accuracy and fairness of the lottery. Utility Model Content

[0004] This invention proposes an automatic ball dispenser for a lottery machine to solve the problems mentioned in the background art, such as the need for manual ball retrieval in existing lottery machines or the simultaneous slippage of multiple balls during rotation.

[0005] The technical solution of this utility model is implemented as follows:

[0006] The automatic ball dispensing box of the lottery machine includes a box body with one end open, and a ball outlet is provided on the side wall of the box body for the ball to enter from the opening end of the box body and exit from the ball outlet.

[0007] A movable baffle is rotatably installed inside the box and between the box opening and the ball outlet. When the movable baffle is rotated to the first extreme position, it can at least partially block the ball outlet to prevent the ball entering from the box opening from falling directly out of the ball outlet. When the movable baffle is rotated to the second extreme position, a ball storage compartment is formed between the movable baffle and the root of the box to accommodate the ball and prevent the ball from being discharged outward.

[0008] Preferably, the fixed end of the movable baffle is located near the inner wall of the box where the ball outlet is located.

[0009] Preferably, when the movable baffle is rotated to the second extreme position, its movable end abuts against the inner wall of the box opposite to the ball outlet.

[0010] Preferably, the inner cavity of the box has a recessed groove on the side wall near the root, and the groove is located on the side wall of the box opposite to the ball outlet.

[0011] Preferably, the groove forms a stepped portion in the direction close to the opening of the box body.

[0012] Preferably, a limiting hole is formed inside the groove.

[0013] Preferably, the inner wall surface between the opening of the box and the step is an inclined surface.

[0014] Preferably, the width of the inner cavity of the box gradually increases from the root of the inner cavity to the opening.

[0015] Preferably, the box body has outwardly extending collection plates on both sides of the opening.

[0016] By adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0017] This invention utilizes the opening and closing of a movable baffle in conjunction with the angle changes during the rotation of the ball dispenser box to achieve precise control over the number and timing of ball dispensing.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] like Figure 1-3 As shown, the automatic ball dispensing box of the lottery machine includes a box body 1 with one end open. The box body 1 is made of acrylic sheet, plastic sheet or metal sheet. When in use, it is installed inside the roller 3 of the lottery machine. The side wall of the box body 1 is provided with a ball outlet 105 for the ball to enter from the opening end of the box body 1 and exit from the ball outlet 105.

[0033] A movable baffle 101 is rotatably installed inside the box 1 and between the opening of the box 1 and the ball outlet 105. When the box 1 rotates together with the roller 3, the movable baffle 101 can rotate to a first limit position and a second limit position under its own gravity. In the first limit position, the movable baffle 101 is horizontal relative to the inner wall of the box 1, and the ball can enter the box 1 from the opening. When the movable baffle 101 rotates to the first limit position, it can at least partially block the ball outlet 105 to prevent the ball entering from the opening of the box 1 from falling directly out of the ball outlet 105. When the movable baffle 101 rotates to the second limit position, the movable baffle 101 is in an inclined state inside the box 1, and a ball storage chamber is formed between the movable baffle 101 and the root of the box 1 to accommodate the ball and prevent the ball from being discharged outward.

[0034] Furthermore, when the movable baffle 101 is in the second extreme position, only a single ball is allowed to be contained in the ball storage compartment formed by the box 1 and the movable baffle 101.

[0035] Specifically, the fixed end 102 of the movable baffle 101 is located near the inner wall of the box 1 where the ball outlet 105 is located, so that when the movable baffle 101 is in the first extreme position, it can remain flush with the inner wall of the box 1, preventing the fixed end 102 from causing the ball to be unable to enter the box 1. In this example, the movable baffle 101 is installed in the box 1 by a pin.

[0036] Specifically, when the movable baffle 101 rotates to the second limit position, its movable end 103 abuts against the inner wall of the box 1 opposite to the ball outlet 105. That is, the inner wall of the box 1 limits the movable end 103 of the movable baffle 101 to prevent the movable baffle 101 from rotating further. In addition, it can be understood that when the movable baffle 101 rotates to the second limit position, the movable end 103 does not need to contact the inner wall of the box 1. The movable baffle 101 can also be limited by setting a protrusion on the side wall of the box 1.

[0037] Specifically, the inner cavity of the box 1 has a recessed groove 107 on the side wall near the root. The groove 107 is located on the side wall of the box 1 opposite to the ball outlet 105. This is designed so that the ball that first enters the inner cavity of the box 1 falls into the groove 107, preventing the ball from easily detaching from the inner cavity of the box 1. More specifically, the groove 107 forms a stepped portion 108 in the direction near the opening of the box 1. The stepped portion 108 can further limit the ball and achieve the effect of preventing it from detaching.

[0038] Specifically, a limiting hole 104 is provided inside the groove 107. The diameter of the limiting hole 104 is smaller than the diameter of the sphere, so that a part of the sphere can be placed inside the limiting hole 104. The limiting hole 104 can further limit the sphere.

[0039] Specifically, the inner wall surface of the box body 1 between the opening and the step portion 108 is an inclined surface 109, such as... Figure 3 As shown, the inclined surface 109 causes the internal height of the box 1 to gradually decrease from the opening end inward, so that when the ball is placed in the area where the groove 107 is located, the other balls can be exported from the ball box more quickly.

[0040] Specifically, the width of the inner cavity of the box 1 gradually increases from the root of the inner cavity to the opening, which can be used to more quickly guide the ball into the inside of the box 1.

[0041] Specifically, the box body 1 has outwardly extending collection plates 106 on both sides of the opening. The collection plates 106 extend obliquely to both sides of the box body 1, which can quickly concentrate the balls in the opening area of ​​the box body 1 during the forward rotation, and can also disturb the balls in the roller 3 during the reverse rotation.

[0042] When using this type of lottery machine with an automatic ball dispenser box, such as Figure 4-5 As shown, it is installed inside the roller 3 of the lottery machine. Specifically, in this example, a base 2 is installed below the roller 3, and the base 2 is connected to the roller 3 through a rotating shaft. A rocker arm 4 for driving the roller 3 to rotate is installed at the rotating shaft position. The ball outlet box 1 is installed in the circumferential direction of the roller 3. In this example, the ball outlet box and the cover plate on the roller 3 for sealing are integrally formed. In other embodiments, the ball outlet box is directly installed on the inner wall of the roller 3.

[0043] The work process is as follows Figure 6-10 As shown, the ball enters the box 1 and, during the rotation of the roller 3, is finally exited from the ball outlet 105. Specifically... Figure 6 As shown, roller 3 rotates clockwise. During this rotation, the opening of box 1 faces forward. When box 1 is near its bottom position, the ball enters the interior of box 1 through the opening. As roller 3 continues to rotate, as... Figure 7 As shown, the first ball to enter the inner cavity of box 1 is placed in the ball storage compartment and within the limiting hole 104 at the root of groove 107, achieving a limiting effect. At this time, the movable baffle 101 opens inside box 1 under the action of gravity, separating the ball in the ball storage compartment from the external ball. As the roller 3 continues to rotate, as... Figure 8 As shown, the movable baffle 101 abuts against the inner wall of the box 1, allowing balls outside the ball storage compartment to fall into the roller 3, while balls inside the ball storage compartment are blocked by the movable baffle 101. The roller 3 continues to rotate as shown. Figure 9 As shown, the balls inside the ball storage compartment gradually approach the ball outlet 105 on the side of the box 1, waiting to fall. Figure 10 As shown, with the continued rotation of the roller 3, the ball is discharged from the ball storage chamber through the ball outlet 105 and falls into the collection chamber 201 on the base 2, thus completing the process from ball collection to discharge. This cycle continues until all the required balls are discharged.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
