Description

Technical Field

[0001] This utility model relates to the field of sports training equipment technology, and in particular to a tennis ball collector for tennis training. Background Technology

[0002] With the popularization of sports and the improvement of competitive levels, tennis, as a sport that combines strength, skill, and endurance, has received widespread attention. To improve training efficiency and reduce the time and energy spent retrieving balls during training, tennis ball collectors are widely used as auxiliary training equipment. These devices are typically used to quickly collect tennis balls scattered on the court, facilitating centralized management and reuse, and are widely used in various tennis training venues and educational institutions.

[0003] Existing tennis ball collectors generally employ a rolling disc or roller structure, with its outer wall composed of elastic strips. As the collector rolls on the ground, the balls are compressed by external force and pass through the gaps in the elastic strips into the collection chamber. The interior is usually a sealed or semi-sealed structure to store the collected balls. Some devices also include retaining devices after collection to prevent the balls from falling out. The structural design is relatively simple and suitable for use in scenarios with a large number of tennis balls.

[0004] However, the existing tennis ball collectors have a closed outer wall structure of the rolling disc and no convenient ball retrieval opening. This means that users have to flip the entire device or remove the balls one by one when emptying the collection chamber. This operation is cumbersome and inefficient, which seriously affects the user experience, especially in high-frequency training scenarios. Furthermore, repeated flipping may cause wear and loosening of the device structure, affecting its long-term stability and durability. Utility Model Content

[0024] Reference Figures 1-5An extension rod 6 is fixedly connected to the outer wall of the fixed plate 5. An extension rod 6 has a fixing hole 18 inside, located on the inner wall of the extension rod 6, for inserting a fixing block 22 to lock the handle height. An extension rod 7 is slidably connected to the outer wall of the extension rod 6. A sliding sleeve 8 is rotatably connected to the outer wall of the extension rod 7, fitted onto the outside of the extension rod 7. The sliding sleeve 8 adjusts the handle length by sliding within the sliding groove 19, while simultaneously accommodating and controlling the movement of the elastic plate 21 and the fixing block 22. The sliding sleeve 8 has a sliding groove inside. The inner wall of the groove 19 and the sliding sleeve 8 is rotatably connected to a fixed shaft 20. An elastic plate 21 is fixedly connected to the outer wall of the fixed shaft 20.

The outer wall of the elastic plate 21 is fixedly connected to the second fixed block 22, and the outer wall of the first rolling disc 1 is fixedly connected to a round rod 3. One end of the round rod 3 is fixedly connected to a round rod 3. The round rod 3 is an elastic component evenly distributed between the first rolling disc 1 and the second rolling disc 2. During rolling, it springs... The squeezing action pushes the tennis balls on the ground into the collection chamber. Fixed block 15 is slidably connected to the inner wall of baffle 9. The outer wall of rolling disc 11 has a ball outlet 10, which is used to collect and empty the tennis balls from the collection chamber, improving emptying efficiency. The outer wall of rotating shaft 27 is rotatably connected to the inner wall of connecting box 12. The outer wall of baffle 9 is rotatably connected to the outer wall of rolling disc 11. Fixed block 22 is slidably connected to the inner wall of extension rod 6. Elastic sheet 21 is disposed inside sliding sleeve 8. Both ends of round rod 3 are positioned between rolling disc 11 and rolling disc 22. One of the main rolling structures of the rolling disk 1 device is in contact with the ground and drives the round rod 3 to rotate, thereby realizing the function of grabbing tennis balls on the ground and guiding them into the collection cavity. At the same time, its outer wall is provided with a ball outlet 10 for discharging tennis balls. The connecting plate 2 14 is slidably connected to the inner wall of the connecting box 12.

[0025] Working principle: When a tennis ball collector for tennis training is needed, the operator holds the device and rolls it towards the ground. Rolling disc 1 and rolling disc 2 contact the ground and rotate. The elastic rod 3 on the outer ring grabs the scattered tennis balls during rolling and pushes them into the collection chamber. When it is necessary to empty the tennis balls from the collector, the operator presses the push plate 13 on the outer wall of rolling disc 1. The push plate 13 causes the connecting plate 2 14 to slide along the inner wall of the connecting box 12, thereby compressing the spring 16 and causing the fixing block 15 to disengage from the baffle 9. At this time, the baffle 9 can rotate around the rotating shaft 11, thereby opening the ball outlet 10 on the outer wall of rolling disc 1, achieving rapid ball release. After ball release, the push plate 13 is released, the spring 16 returns to its original position, pushing the connecting plate 2 14 and the fixing block 15 back to their original positions. The baffle 9, in cooperation with the rotating shaft 11 and rolling disc 1... The ball outlet 10 is closed again by rotating it to complete the closing operation. This structure effectively improves the inconvenience of the existing rolling disc not having a convenient opening on its outer wall, which requires the entire disc to be flipped or removed one by one to empty the collected balls. It improves the ball discharge efficiency and reduces the burden of use. In addition, to accommodate users of different heights or to adjust the operating posture, the handle structure adopts a telescopic design. The operator can rotate the sliding sleeve 8 to make the sliding sleeve 8 slide up and down along the extension rod 2 7, so that the fixing block 2 22 slides out from the fixing hole 18 inside the extension rod 1 6, thereby driving the extension rod 2 7 to extend and retract up and down along the extension rod 1 6. After adjustment, the sliding sleeve 8 is rotated back to its original position, and the elastic piece 21 set inside the sliding sleeve 8 elastically resets, driving the fixing block 2 22 to insert into the fixing hole 18 on the inner wall of the extension rod 1 6, realizing the locking and stabilization of the handle position. This structure improves the ergonomic adaptability of the collector and meets the usage needs of different users. The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
