Description

[Technical Field]

[0001] The present invention relates to the field of ball launching machines, and more particularly to ball launching machines. [Background technology]

[0002] In the field of sports training, ball launchers are common assistive devices used by athletes to practice batting and catching. Conventional ball launchers typically can only launch a single type of ball and have limited adjustability, resulting in a lack of training flexibility. The main limitations of current technology are as follows: 1. Adaptability to a single type of ball: Conventional ball-launching machines are designed for a specific type of ball, such as a machine for tennis or a machine for baseball, and cannot accommodate balls of different sizes or weights. This means that users have to purchase multiple machines, which is costly and takes up a lot of space. 2. Inconvenient angle adjustment: Most ball launchers only support a fixed elevation angle or horizontal rotation, and adjusting the angle requires removing screws with a tool, making operation cumbersome. This makes it difficult to reproduce a variety of ball trajectories similar to those seen in actual matches, such as balls with high arcs or side spin. 3. Insufficient stability of ball supply: The gap between the ball launcher and the ball launcher roller is fixed, which makes the balls easily clogged and causes uneven friction, resulting in deviations in launch speed and direction, which not only reduces training efficiency but also may damage the device and balls. Summary of the Invention

[0003] The present invention aims to solve the above problems and provides a ball launching machine.

[0008] The present invention will be described in detail below with reference to the accompanying drawings. As shown in Figure 1, the ball launching machine comprises a ball launching device and a support frame, with the ball launching device mounted on top of the support frame. The ball launching device includes a ball launching tube 1 and a driver 2. A roller housing 3 is mounted on the bottom side of the ball launching tube 1, and a ball launching roller 4 is attached to the output end of the driver 2. The ball launching roller 4 is rotatably disposed within the roller housing 3, and its upper portion extends into the ball launching tube 1. Inside the ball launching tube 1, a conversion plate 5 is mounted above the ball launching roller 4, which can be adjusted according to the size of the ball. In a preferred embodiment of this embodiment, the ball-launching tube 1 includes a pair of symmetrically arranged side members 101, and the roller housing 3 includes a pair of symmetrical side covers 301. Each side member 101 is integral with the corresponding side cover 301, which stabilizes the connection between the ball-launching tube and the roller housing and improves structural strength. In a preferred embodiment of this embodiment, as shown in FIG. 6, an arc-shaped guide tube 6 is provided at the entrance of the ball-launching tube 1, and an elevation angle adjustment handle 7 is provided at the bottom of the arc-shaped guide tube 6. At the entrance of the ball-launching tube 1, a locking groove 8 is provided on the inside of each side member 101, and a locking block 9 that engages with the locking groove 8 is provided at the exit of the arc-shaped guide tube 6. A locking member 10 is provided below the arc-shaped guide tube 6 between the two locking grooves 8, and includes a bolt 15 and a pentagonal nut 16. The angle of the arc-shaped guide tube 6 can be adjusted by loosening the pentagonal nut 16, and the angle is fixed by tightening the pentagonal nut 16 after adjustment. To ensure a locking effect, the inner wall of the locking groove and the outer surface of the locking block are formed with meshable teeth, as shown in FIG. 6.

[0009] In a preferred embodiment of this embodiment, as shown in Figure 2, ball guide ribs 11 are provided on the inner wall of the ball launching tube 1, i.e., on both sides, above, and in front of the ball launching roller 4. The ball guide ribs 11 help balls to be launched smoothly from the ball launching tube 1. The upper part of the outlet of the ball launching tube 1 is inclined upward to form an inclined surface 12. When the ball launching tube 1 is raised upward, the inclined surface 12 forms an expanded portion at the tube opening, reducing the resistance to the ball launch, preventing ball jamming, and facilitating smooth launching. In a preferred embodiment of this embodiment, a coupler is provided between the launching device and the support frame, as shown in Figure 2. The coupler includes a first connecting block 13 that is detachably connected to the support frame, and a second connecting block 14 that is detachably connected to the elevation angle adjustment handle 7. The elevation angle adjustment handle 7 is provided with a bolt 15 that passes through the elevation angle adjustment handle 7 and the second connecting block 14, and a pentagonal nut 16 is threaded onto the bolt 15. As shown in Figure 3, a toothed plate 17, coaxial with the bolt 15, is fixed to the side of the elevation adjustment handle 7 closest to the second connecting block 14. A toothed plate 17, coaxial with the bolt 15, is also provided on the ball launching device side of the second connecting block 14. An annular arrangement of interlocking teeth 18 is provided on the opposing sides of both toothed plates 17. The angle between the ball launching device and the second connecting block 14 can be adjusted by loosening the pentagonal nut 16, and the adjustment can be completed by tightening the nut. The design of the interlocking teeth 18 ensures stability after fixation.

[0010] 1 and 5, in a preferred embodiment of this embodiment, the support frame includes a C-frame 19, a vertical support 20, and a tripod stand 21. A sleeve 22 is provided at both the lower end of the C-frame 19 and the upper end of the tripod stand 21. The sleeve 22 at the lower end of the C-frame 19 fits onto the upper end of the vertical support 20, and the sleeve 22 at the upper end of the tripod stand 21 fits onto the lower end of the vertical support 20. A fastening bolt 23 is provided between the sleeve 22 at the lower end of the C-frame 19 and the vertical support 20, and between the sleeve 22 at the upper end of the tripod stand 21 and the vertical support 20. As a result, the tripod stand 21 is connected to the lower part of the vertical support 20 via the sleeve 22 and the fastening bolt 23, and the lower end of the C-frame 19 is connected to the upper end of the vertical support 20 via the sleeve 22 and the fastening bolt 23. When adjusting the horizontal angle, the tightening bolt 23 provided on the sleeve 22 of the C-shaped frame 19 is loosened, and after adjusting the angle, it can be fixed by tightening it. As shown in Figure 4, a toothed plate 17 is fixed to the upper end of the C-shaped frame 19 via a locking device 24. A toothed plate 17 is also provided on the C-shaped frame 19 side of the first connecting block 13, and annularly arranged meshing teeth 18 are provided on opposing sides of both toothed plates 17. The upper end of the C-shaped frame 19, both toothed plates 17, and the first connecting block 13 are connected by bolts 15 and pentagonal nuts 16. The angle between the first connecting block 13 and the support frame can be adjusted by loosening the pentagonal nuts 16, and after adjustment, the first connecting block 13 can be fixed by tightening them. The design of the meshing teeth 18 ensures stability after fixing. The conversion plate 5 of the present invention can be replaced with a suitable conversion plate when launching different types of balls, allowing the launch tube to adapt to balls of different diameters, such as baseballs, tennis balls, etc. This solves the problem that conventional ball launchers are limited to a single type of ball. The bulb tube 1 of this invention is constructed integrally with a pair of symmetrically arranged side members and the corresponding side covers of the roller housing, which makes the structure stable and easy to maintain. The array of ball guide ribs 11 of the present invention is provided around the periphery of the launch roller to guide the ball precisely into the friction area of ​​the launch roller, thereby improving the consistency of the launch trajectory. The quick-release support rack of this invention uses a sleeve-type connection, where the C-frame 19 and tripod stand 21 are fitted to the vertical support 20 via a sleeve 22, and then fixed together with a fastening bolt 23. A locking device 24 locks the corresponding toothed plate 17 onto the C-frame 19, which is then secured with a bolt 15 and a pentagonal nut 16. This allows for quick assembly, disassembly, and storage of the support rack. This device is applicable to sports training facilities, schools, and home environments, and can meet the needs of different age groups and training intensities, especially for comprehensive training scenarios that require switching between different types of balls.
