[0033] Embodiment 1:

[0034] The embodiment of the present utility model provides a billiard ball placement and clamping device, as Figures 1-7As shown in the figure, it includes: a pendulum ball frame 1, in which a ball pushing plate 2, a ball placing plate 3 and a ball fixing plate 4 are sequentially arranged at intervals from top to bottom. One side of the ball fixing plate 4 is connected to the pendulum ball frame 1. The ball pushing plate 2 is slidably arranged above the ball fixing plate 4. The ball placing plate 3 is arranged between the ball fixing plate 4 and the ball pushing plate 2 and is connected to the ball pushing plate 2. The ball pushing plate 2, the ball placing plate 3 and the ball fixing plate 4 are provided with corresponding holes for placing billiard balls. The ball pushing plate 2 is connected to the ball fixing plate 4 through a sliding mechanism. The upper surface of the ball placing plate 3 is connected to the lower surface of the ball pushing plate 2 through a plurality of connecting rods 5. A plurality of first placing holes 6 are arranged in the ball pushing plate 2, and the plurality of first placing holes 6 form a ball placing area. A plurality of second placing holes 7 are arranged in the ball placing plate 3, and the second placing holes 7 are concentric with the first placing holes 6. A plurality of positioning holes 8 are arranged in the ball fixing plate 4, and a driving mechanism 9 is arranged on the ball fixing plate 4. The output end of the driving mechanism 9 is connected to the side wall of the ball pushing plate 2.

[0035] The working principle and beneficial effects of the above technical solution are as follows: First, place the billiard balls in the ball-pushing plate 2 and the ball-placing plate 3 of the ball-holding frame 1. The ball-pushing plate 2, the ball-placing plate 3, and the ball-positioning plate 4 are provided with corresponding holes. The holes include a first placement hole 6 provided in the ball-pushing plate 2, a second placement hole 7 provided in the ball-placing plate 3, and a positioning hole 8 provided in the ball-positioning plate 4. The first placement hole 6 of the ball-pushing plate 2 and the second placement hole 7 of the ball-placing plate 3 are concentrically arranged. The first placement hole 6 and the second placement hole 7 are used to hold the billiard balls. Both the first placement hole 6 and the second placement hole 7 are set to 15. All the first placement holes 6 form a ball-placement area and are distributed in a triangular shape, which can hold all the billiard balls. Initially, the device is in the ball-holding state. The centers of the first placement hole 6 and the positioning hole 8 are misaligned. Therefore, the billiard balls in the first placement hole 6 will not fall through the positioning hole 8. At this time, the billiard balls can be placed in the ball-placing plate 3 and the ball-pushing plate 2, so that the billiard balls are kept on the ball-positioning plate 4. The ball-positioning plate 4 is arranged at the bottom of the ball-holding frame 1, and the ball-positioning plate 4 can support the billiard balls. When the device is at a predetermined position on the billiard table, pushing the ball-pushing plate 2 to move can drive the billiard balls to roll on the ball-positioning plate 4. Preferably, a driving mechanism 9 is arranged on the ball-positioning plate 4. Starting the driving mechanism 9, the driving mechanism 9 can drive the ball-pushing plate 2 to move. The ball-pushing plate 2 drives the ball-placing plate 3 to move synchronously through the connecting rod 5. The driving mechanism 9 can be selected from existing mechanisms such as a lead screw motor and an electric push rod that can automatically expand and contract. The ball-pushing plate 2 slides above the ball-positioning plate 4 through a sliding mechanism. The ball-pushing plate 2 pushes the billiard balls to roll through the first placement hole 6 until the centers of the corresponding first placement hole 6, second placement hole 7, and positioning hole 8 are on the same straight line. Then, the billiard balls can fall onto the billiard table through the positioning hole 8 under the action of gravity. At this time, the device is in the ball-releasing state. After the ball release is completed, control the driving mechanism 9 to return to its original position, so that the first placement hole 6 and the positioning hole 8 are misaligned again, which is convenient for the next ball-holding. In the present utility model, by arranging the ball-placing plate 3 between the ball-pushing plate 2 and the ball-positioning plate 4, the second placement hole 7 of the ball-placing plate 3 can limit the billiard balls and restrict the lateral rolling of the billiard balls, so that the billiard balls move downward in the cylindrical space formed by the first placement hole 6 and the second placement hole 7, avoiding the billiard balls quickly rolling into the positioning hole 8 of the ball-positioning plate 4, thereby slowing down the falling speed of the billiard balls, preventing the billiard balls from hitting the billiard table quickly, and reducing the noise when the billiard balls are placed. The ball-pushing plate 2, the ball-placing plate 3, and the ball-positioning plate 4 all adopt a thin plate structure, which can reduce the mass of the device and lower the manufacturing cost.

[0036] Embodiment 2

[0037] Based on the above Embodiment 1, as Figure 2 shown, the sliding mechanism includes first guide shafts 10 symmetrically arranged on the left and right sides of the ball-placing plate 3. The two first guide shafts 10 are parallel to each other. Fixed seats 11 are arranged at both ends of the first guide shafts 10. The fixed seats 11 are connected to the upper surface of the ball-positioning plate 4. Sliders 12 are slidably arranged on the first guide shafts 10. The upper surface of the sliders 12 is connected to the lower surface of the ball-pushing plate 2.

[0038] The working principle and beneficial effects of the above technical solution are as follows: When the driving mechanism 9 drives the ball pushing plate 2 to move, the ball pushing plate 2 drives the slider 12 to slide on the first guiding shaft 10. The two parallel guiding shafts can provide guidance for the movement of the ball pushing plate 2, making the movement of the ball pushing plate 2 more stable and reliable, and ensuring that the first placement hole 6 can be aligned with the positioning hole 8.

[0039] Embodiment 3

[0040] Based on Embodiment 1 or 2, as Figure 2 shown, a cover plate 13 is provided above the ball placing area. The lower surface of the cover plate 13 is connected to the upper surface of the ball swinging frame 1. A first through hole 14 is provided inside the cover plate 13, and the cross-sectional area of the first through hole 14 is larger than the cross-sectional area of the ball placing area.

[0041] The working principle and beneficial effects of the above technical solution are as follows: The cover plate 13 is provided on the upper surface of the ball swinging frame 1, which can block the inside of the ball swinging frame 1. A first through hole 14 is provided on the cover plate 13, and the first through hole 14 is triangular in shape. The billiard ball can be placed into the ball pushing plate 2 and the ball placing plate 3 through the first through hole 14.

[0042] Embodiment 4

[0043] Based on any one of Embodiments 1-3, the diameters of the first placement hole 6, the second placement hole 7, and the positioning hole 8 are the same, and the diameters of the first placement hole 6, the second placement hole 7, and the positioning hole 8 are larger than the diameter of the billiard ball.

[0044] The working principle and beneficial effects of the above technical solution are as follows: The diameters of the first placement hole 6, the second placement hole 7, and the positioning hole 8 are the same and are slightly larger than the diameter of the billiard ball, ensuring that the billiard ball can smoothly pass through the first placement hole 6, the second placement hole 7, and the positioning hole 8 and fall onto the billiard table.

[0045] Embodiment 5

[0046] Based on any one of Embodiments 1-4, the distance between the ball pushing plate 2 and the ball fixing plate 4 is less than the diameter of the billiard ball, and the distance between the ball pushing plate 2 and the ball placing plate 3 is less than the radius of the billiard ball.

[0047] The working principle and beneficial effects of the above technical solution are as follows: The distance between the ball pushing plate 2 and the ball fixing plate 4 is less than the diameter of the billiard ball and greater than the radius of the billiard ball, ensuring that during the movement of the ball pushing plate 2, the billiard ball will not roll out above the first placement hole 6. The distance between the ball pushing plate 2 and the ball placing plate 3 is less than the radius of the billiard ball. During the rolling of the billiard ball, the billiard ball can be laterally limited by the second placement hole 7. With the addition of the ball placing plate 3, the lateral rolling distance of the billiard ball can be increased, the falling speed of the billiard ball can be slowed down, the falling height of the billiard ball can be reduced, thereby reducing the noise generated when the billiard ball lands on the billiard table.

[0048] Example 6

[0049] Based on any one of Embodiments 1-5, as Figures 3-5 shown, a tightening plate 15 is arranged below the fixed ball plate 4. A second through hole 16 is arranged in the tightening plate 15. The cross-sectional area of the second through hole 16 is larger than the cross-sectional area of the ball placing area. At the four corners of the upper surface of the tightening plate 15, second guide shafts 17 are arranged. Linear bearings 18 are arranged at the upper ends of the second guide shafts 17. The upper ends of the linear bearings 18 are connected to the inner wall of the upper end of the ball swinging frame 1;

[0050] A plurality of third through holes 19 are arranged in the tightening plate 15;

[0051] The cross-section of the second through hole 16 is triangular. Three adjusting plates 20 are arranged on the upper surface of the tightening plate 15. The three adjusting plates 20 are distributed in an annular array about the center of the second through hole 16. One end of the adjusting plate 20 is connected to the collecting plate, and the other end of the adjusting plate 20 extends above the second through hole 16;

[0052] A chamfer is arranged on the upper surface of the end of the adjusting plate 20 close to the second through hole 16.

[0053] The working principle and beneficial effects of the above technical solution are as follows: The distance between the existing tightening plate 15 and the fixed ball plate 4 is fixed. Therefore, the falling height of the billiard ball is fixed and the falling height is relatively high. The noise generated by the billiard ball hitting the billiard table when it falls is also relatively large. To solve the above problems, in this application, a tightening plate 15 is arranged below the fixed ball plate 4. After the tightening plate 15 contacts the billiard table, as the ball swinging frame 1 moves downward, the second guide shaft 17 slides in the linear bearing 18, and the distance between the tightening plate 15 and the fixed ball plate 4 decreases, and the falling height of the billiard ball also decreases accordingly, so as to achieve the effect of reducing the placement noise; when the billiard ball falls on the billiard table through the fixed ball plate 4, multiple billiard balls are located in the second through hole 16 of the tightening plate 15. Three adjusting plates 20 are arranged on the tightening plate 15. One side of the adjusting plate 20 close to the second through hole 16 extends above the second through hole 16. The three adjusting plates 20 respectively correspond to the three linear hole walls of the second through hole 16, and the end of the adjusting plate 20 is parallel to the corresponding hole wall, and the end of the adjusting plate 20 extends beyond the hole wall. Therefore, when the billiard ball falls into the second through hole 16, through the guiding of the edge billiard ball by the adjusting plate 20, the adjacent billiard balls can be in contact with each other, the billiard balls are in close contact, the gap between the billiard balls is eliminated, and the purpose of tightening the billiard balls is achieved. A chamfer is arranged at the end of the adjusting plate 20 close to the second through hole 16, and the edge billiard ball can roll along the chamfer, further slowing down the falling speed of the billiard ball and achieving the effect of gradually tightening. A plurality of third through holes 19 are arranged on the tightening plate 15, which can reduce the mass of the tightening plate 15.

[0054] Example 7

[0055] Based on any one of Embodiments 1-6, asFigure 6 , Figure 7 As shown in Figure 7 , an equilateral triangle structure is formed among three adjacent second placement holes 7, and a clamping mechanism is arranged at the center of the equilateral triangle structure. The clamping mechanism includes a fixed block 21. The upper end of the fixed block 21 is connected to the lower surface of the ball placing plate 3. Three sliding holes 22 are arranged in the fixed block 21. The three sliding holes 22 correspond to three adjacent second placement holes 7 one by one. A connecting spring 23 is arranged in the sliding hole 22. One end of the connecting spring 23 is connected to the inner wall of the sliding hole 22, and the other end of the connecting spring 23 is connected to one end of a limiting rod 24. The limiting rod 24 is slidably connected to the inner wall of the sliding hole 22. The end of the limiting rod 24 away from the connecting spring 23 extends below the second placement hole 7 and is provided with an anti-slip strip 25.

[0056] The working principle and beneficial effects of the above technical solution are as follows: A clamping mechanism is arranged on the lower surface of the ball placing plate 3, and the clamping mechanism is used to clamp the billiard ball located in the second placement hole 7. Specifically, when the billiard ball is located in the second placement hole 7, under the elastic force of the connecting spring 23, the anti-slip strip 25 contacts the side wall of the billiard ball. The anti-slip strip 25 is made of an elastic anti-slip material, which can increase the friction between the anti-slip strip 25 and the side wall of the billiard ball, and clamp the billiard ball in the second placement hole 7 through the cooperation with the hole wall of the second placement hole 7 and the support of the ball fixing plate 4, improving the stability of the billiard ball placement. When the second placement hole 7 is aligned with the positioning hole 8, the billiard ball moves downward under the action of gravity. The anti-slip strip 25 first drives the limiting rod 24 to slide into the sliding hole 22, and the connecting spring 23 is compressed. When the center height of the billiard ball is lower than the anti-slip strip 25, under the elastic force of the connecting spring 23, the limiting rod 24 slides out of the sliding hole 22. Under the action of the connecting spring 23, the anti-slip strip 25 can always contact the side wall of the billiard ball at different heights until the anti-slip strip 25 is separated from the billiard ball. Through the contact between the anti-slip strip 25 and the side wall of the billiard ball, the falling speed of the billiard ball can be slowed down, and the noise of the billiard ball placement can be further reduced.
