[0001] This utility model belongs to the field of ball-pinning devices, specifically relating to a portable automatic ball-pinning device. Background Technology

[0002] A portable automatic ball dropper is a device that can be easily carried outdoors or indoors and automatically drops balls. It is suitable for sports training such as golf and tennis, as well as animal training. Its design usually emphasizes compactness, no power supply required, easy portability, and the ability to provide an efficient training experience in different environments.

[0003] Existing pinball machines all adopt an active structure design with built-in batteries and are controlled by remote control signals. However, the structure design with a power supply has problems such as: the need for regular maintenance of electronic equipment, the communication signal being affected by environmental factors affecting the remote control signal, battery electronic components aging, and insufficient power to use the equipment in emergency situations. In addition, pinball machines with a power supply are not only larger and heavier, making them inconvenient to carry, but also have difficulty catching balls that have fallen on the ground.

[0004] Therefore, in response to the problems of existing automatic pinball machines being prone to malfunction, inconvenient to carry, and having limited functionality, a portable automatic pinball machine is developed. By adding a bolt-action mechanism, a lightweight and convenient structure, and a movable gripping mechanism to the automatic pinball machine, it can operate without a power source. The purely mechanical ejection mechanism can reduce the failure rate of the device during use, making it easy to use and carry. It can also prevent the ball from falling out and make it easy for the user to store the ball inside the pinball machine. Utility Model Content

Furthermore, the main body of the pinball machine, consisting of a ball cup 1, a hand handle 2, and a base 3, is lighter and more portable, and can be placed in a pocket for easy use and carrying. The two sets of fixed claws 8, together with the two sets of movable claws 23 driven by the elastic rope 24 driven by the hand button 5, can close or open the upper end of the ball cup 1 to limit and hold the ball stored in the ball cup 1, preventing the ball from falling out of the ball cup 1. The movable claws 23 also make it easy for the user to grab the ball that has fallen to the ground and place it on the inner wall of the ball cup 1, so that the user does not need to directly touch the ball that has fallen to the ground.

[0031] Please see Figures 3-7 In this embodiment, the inner wall of the handheld lever 2 is provided with four sets of limiting grooves 16 evenly distributed around the circumference of the handheld lever 2. The outer wall of the metal firing pin 4 is fixedly provided with four sets of limiting blocks 19 evenly distributed around the circumference of the metal firing pin 4. The limiting blocks 19 are adapted to the limiting grooves 16. In use, the limiting blocks 19 cooperate with the limiting grooves 16 to improve the stability of the metal firing pin 4 when it moves along the spring groove 15 when the first spring 6 pushes the metal firing pin 4 to pop the ball outward. The front end of the handheld lever 2 is fixedly provided with a protective frame 10. The lower end of the inner wall of the first groove 12 is fixedly provided with an extension frame 11. The tail end of the second spring 27 is fixedly provided with the extension frame 11. The tail end of the first spring 6 is fixed to the lower inner wall of the spring groove 15. In use, the first spring 6 can assist the metal firing pin 4 to pop the ball outward, while the second spring 27 can support and fix the interlocking first locking block 20 and second locking block 28. The lower end of the base 3 is provided with a third groove 14, and the lower end of the third groove 14 is provided with a second groove 13. The upper end of the base 3 is provided with a through hole 9 that communicates with the second groove 13. The elastic rope 24 passes through the through hole 9. In use, the elastic rope 24 can be kept taut when not in use so that the two sets of movable claws 23 rotatably mounted on the hinge frame 7 remain in a closed position.

[0032] Please see Figures 6-8 In this embodiment, a first sliding groove 17 is provided through the inner wall of the right end of the spring groove 15, and a second sliding groove 18 is provided on the inner wall of the front end of the spring groove 15. The outer wall of the handle 22 is in contact with the inner wall of the first sliding groove 17, and the outer wall of the first locking block 20 is in contact with the inner wall of the second sliding groove 18. In use, the first sliding groove 17 can provide a limiting assistance to the handle 22 to improve the stability of the user when pulling the handle 22. The second sliding groove 18 can provide a limiting assistance to the first locking block 20 to improve the stability of the interlocking of the first locking block 20 and the second locking block 28.

[0033] Please see Figures 3-10 In this embodiment, the first locking block 20 and the second locking block 28 are adapted to each other. The limiting plate 25 is movably disposed in the second groove 13. The inner wall of the third groove 14 is in contact with the outer wall of the hand button 5. In use, the third groove 14 can provide limiting assistance to the hand button 5 to improve its stability during use. The second groove 13, together with the limiting plate 25, can prevent the limiting plate 25 and the hand button 5 from falling off the base 3. The first groove 12 and the second sliding groove 18 are interconnected. The firing block 26 is located on the inner wall of the protective frame 10. The fixed claw 8 and the movable claw 23 are both arc-shaped. In use, the firing block 26 located in the protective frame 10 can prevent the user from accidentally touching the interlocking first locking block 20 and the second locking block 28 to prevent the first spring 6 under compression from accidentally pushing out the metal firing pin 4.

[0034] In use, by pulling the hand button 5, the limiting plate 25 is moved up and down along the inner wall of the second groove 13, which drives the two elastic ropes 24 to rotate and open the two sets of movable claws 23. Then, the user aligns the ball cup 1 with the ball on the ground and squeezes the ball into the ball cup 1. Then, as described above, the two sets of movable claws 23 cooperate with the two sets of fixed claws 8 to close the upper end of the ball cup 1, so as to limit and clamp the ball stored in the ball cup 1, thereby preventing the ball from falling out of the ball cup 1.

[0035] Next, the user pulls the handle 22 along the inner wall of the first slide groove 17 to drive the metal striker 4 and the limiting block 19 to compress the first spring 6 downward along the inner wall of the spring groove 15 and the inner wall of the limiting groove 16. The metal striker 4 drives the first locking block 20 to engage with the second locking block 28 along the inner wall of the second slide groove 18. The second spring 27 supports and fixes the engaging first locking block 20 and the second locking block 28 to limit and fix the first spring 6 in the compressed state.

[0036] When the ball needs to be ejected, the user moves the firing block 26 to release the second locking block 28 from the first locking block 20, so that the compressed second spring 27 pushes the metal firing pin 4 to eject the ball stored in the ball cup 1. The fixed claw 8 and the movable claw 23, which are hinged to the hinge frame 7, will rotate as the ball is ejected to avoid blocking the ball from being ejected.

[0037] Through the above steps, the bolt structure consisting of the pull handle 22, the metal firing pin 4, the first spring 6, and the first locking block 20, combined with the firing structure consisting of the first locking block 20, the firing block 26, and the second spring 27, can operate without power. The purely mechanical ejection structure can also reduce the failure rate of the device during use. Furthermore, the main body of the ball-pinning device, consisting of the ball cup 1, the hand handle 2, and the base 3, is lighter and more portable, making it easier to use and carry. The two sets of fixed claws 8, together with the two sets of movable claws 23 driven by the elastic rope 24 driven by the hand button 5, can close or open the upper end of the ball cup 1 to limit and clamp the ball stored in the ball cup 1, preventing the ball from falling out of the ball cup 1. It also allows the user to easily grab the ball onto the inner wall of the ball cup 1 without contact. This solves the problems of existing automatic ball-pinning devices, which are not only prone to failure during use but also inconvenient to carry and have relatively limited functions.

[0038] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
