Description

Technical Field

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

[0002] Tennis training equipment is a set of devices used for regular tennis practice. It typically includes a screen, a ball machine, and a ball collection box. The ball machine is located inside the collection box, and the screen is positioned above it. To use it, a tennis ball is placed in the ball machine, which launches it. The player uses a tennis racket to hit the ball against the screen. The flexible screen absorbs the force of the ball, causing it to fall into the open collection box. The training process is simply a repetition of this process.

[0003] However, due to differences in the angle and force of the shot, not all tennis balls will land in the ball collection box. Some balls will always fall to the ground outside the box, requiring manual collection before being put back into the ball machine. This process is tedious and inefficient. Furthermore, the ball collection box only holds the fallen balls; they still need to be manually placed into the ball machine, making it inconvenient to use. Summary of the Invention

[0004] In order to solve the problems existing in the background art, this utility model proposes a ball receiving structure for tennis training equipment.

[0005] A ball-collecting structure for tennis training equipment includes a ball-collecting box and a ball-serving machine disposed within the ball-collecting box. The structure includes an automatic ball-collecting mechanism, a guide plate, and a guide channel. The automatic ball-collecting mechanism includes a drive motor, a driving gear, a first driven gear, a second driven gear, a lifting tube, a chain, and ball-gathering plates all disposed on one side of the chain. The drive motor is disposed on the lower part of one side of the ball-collecting box and drives the driving gear. The first driven gear is rotatably disposed on the upper part of one side of the ball-collecting box and is positioned corresponding to one end of the guide channel. The second driven gear is located at the lower part of the other side inside the ball receiving box. The chain is wound around the driving gear, the first driven gear, and the second driven gear respectively. The lifting tube is sleeved on the chain and ball collecting plate between the driving gear and the first driven gear. The other end of the guide groove is located corresponding to the ball launching machine, and one end of the guide groove is higher than the other end of the guide groove. The guide plate is inclinedly located at the bottom of the ball receiving box as the bottom plate, and one end of the guide plate is inclined downward toward the chain between the second driven gear and the driving gear.

[0006] Based on the above, the other end of the guide plate is provided with a slope, and the front side of the ball receiving box is provided with a flexible cloth curtain.

[0007] Based on the above, an auxiliary rod is provided on the lower rear side of the ball receiving box corresponding to the chain. An L-shaped first stop bar is provided on the upper part of the auxiliary rod facing the chain, and an L-shaped second stop bar is provided on the lower part of the auxiliary rod facing the chain. The chain runs in the gap between the first and second stop bars. A ball-gathering gap is provided between the second stop bar and one end of the guide plate. The width of the ball-gathering gap is smaller than the diameter of the tennis ball. The ball-gathering plate on the chain between the second driven gear and the driving gear runs in the ball-gathering gap.

[0008] Based on the above, the lower part of the lifting tube is provided with a ball inlet and the upper part is provided with a ball outlet. The lower part of the ball inlet is provided with an arc-shaped lifting part corresponding to the ball gathering gap. An observation groove is opened on the side of the lifting tube facing the chain. The width of the lifting tube is adapted to the diameter of the tennis ball.

[0009] Based on the above, the ball-gathering plate is inclinedly disposed on one side of the chain, and the angle between the ball-gathering plate and the conveying direction of the chain is an obtuse angle.

[0010] Based on the above, one end of the guide channel is located below the ball outlet, and the bottom of one end of the guide channel is provided with a running slot corresponding to the ball collecting plate.

[0011] A tennis training device includes a ball machine, a ball collection box, and a screen. The ball machine is installed inside the ball collection box, the screen is installed above the ball collection box, and a ball collection structure is installed inside the ball collection box. The ball collection structure uses the ball collection structure of any of the tennis training devices described above.

[0012] This utility model has substantial features and advancements compared to the prior art, specifically:

[0013] 1. This utility model automatically guides the tennis balls falling into the ball collection box to the ball gathering plates on the automatic ball collection mechanism conveyor chain by setting an inclined guide plate at the bottom of the ball collection box. The ball gathering plates, driven by the chain, transport the tennis balls through the lifting pipe to the guide trough. After the tennis balls pass through the inclined guide trough, they automatically roll down to the ball serving machine, thereby realizing automatic ball collection. There is no need to manually add balls to the ball serving machine, which greatly improves the convenience of use.

[0014] 2. By setting a flexible curtain at the front of the ball collection box and setting a slope at the other end of the guide plate, tennis balls that fall outside the ball collection box can be directly gathered at the front of the ball collection box using a tool with wooden strips or scrapers. Then, the tennis balls can be pushed into the ball collection box from under the flexible curtain through the slope, avoiding the need to pick up the tennis balls one by one and further improving the efficiency of use.

[0021] 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.

[0022] A ball-collecting structure for tennis training equipment, such as Figures 1-4As shown, the tennis training equipment includes a ball collection box 1 and a ball serving machine 2. The ball serving machine 2 is located inside the ball collection box 1, and a ball serving port is provided on the front side of the ball collection box 1 corresponding to the ball serving machine 2. The ball collection structure includes an automatic ball collection mechanism, a guide plate 3, and a guide channel 9. The bottom plate of the ball collection box 1 is the guide plate 3, which is inclined and slopes downwards towards the chain 4 of the automatic ball collection mechanism (in this embodiment, chain and gear transmission is preferred; in other embodiments, a transmission belt and transmission wheel can also be used for transmission), so that the tennis balls falling into the ball collection box 1 roll along the inclined guide plate 3 under their own gravity to the ball gathering plates 8. The automatic ball-collecting mechanism includes a drive motor 15, a drive gear 16, a first driven gear 12, a second driven gear 5, a lifting tube 7, a chain 4, and multiple ball-collecting plates 8. The ball-collecting plates 8 are evenly spaced on the side of the chain 4 near the guide plate 3. The drive gear 16 and the drive motor 15 are respectively located in the lower part of one side of the ball-collecting box 1, and the drive motor 15 drives and connects to the drive gear 16. The first driven gear 12 is rotatably located in the upper part of one side of the ball-collecting box 1, above the drive motor 15, and corresponding to one end of the guide trough 9. The other end of the guide trough 9 corresponds to the ball-serving machine 2. The guide trough 9 is inclined as a whole, and the end of the guide trough 9 near the ball-serving machine 2 is lower in height. Therefore, tennis balls entering the guide trough 9 can automatically roll down the guide trough 9 to the ball-serving machine 2 under their own gravity. The second driven gear 5 is located in the lower part of the other side of the ball receiving box 1. The chain 4 is respectively wound around the driving gear 16, the first driven gear 12 and the second driven gear 5. After the drive motor 15 is connected to the mains power through the wire and plug, the drive motor 15 works and drives the chain 4 through the driving gear 16. The tennis balls that fall into the ball receiving box 1 roll down between the ball gathering plate 8 between the second driven gear 5 and the driving gear 16 under the action of the guide plate 3. Under the drive of the chain 4, the ball gathering plate 8 drives the tennis balls to move towards the lifting section of the chain 4. The chain 4 and ball-gathering plate 8 between the driving gear 16 and the first driven gear 12 form the lifting section. The lifting tube 7 is sleeved outside the chain 4 and ball-gathering plate 8 between the driving gear 16 and the first driven gear 12. After the ball-gathering plate 8 brings the tennis ball into the lifting tube 7, under the joint support of the ball-gathering plate 8 and the lifting tube 7, the tennis ball moves upward with the chain 4 and the ball-gathering plate 8 to the ball outlet 18 of the lifting tube 7. Due to the change in the movement direction of the chain 4 and the ball-gathering plate 8, the ball-gathering plate 8 pushes the tennis ball from the ball outlet 18 to the guide groove 9. The tennis ball that enters the guide groove 9 automatically rolls down along the guide groove 9 to the ball-serving machine 2, completing the automatic collection of the tennis ball that falls into the ball collection box 1.

[0023] In this embodiment, to prevent the tennis ball from rolling around after falling into the ball collection box 1 and affecting the transmission of the chain 4, an auxiliary rod 10 is provided on the lower rear side of the ball collection box 1 corresponding to the chain 4, such as... Figure 5As shown, an L-shaped first stop bar 20 is provided on the upper part of the auxiliary rod 10 facing the chain 4, and an L-shaped second stop bar 19 is provided on the lower part of the auxiliary rod 10 facing the chain 4. A gap is formed between the first stop bar 20 and the second stop bar 19. The chain 4 runs within the gap between the first stop bar 20 and the second stop bar 19. The first stop bar 20 can protect the chain 4 and prevent the tennis ball from rolling directly onto the chain 4. A ball-gathering gap is provided between the second stop bar 19 and one end of the guide plate 3. The width of the ball-gathering gap is smaller than the diameter of the tennis ball. The ball-gathering plate 8 on the chain 4 between the second driven gear 5 and the driving gear 16 runs within the ball-gathering gap. The tennis ball that falls into the ball collection box 1 will roll into the ball-gathering gap between the ball-gathering plates 8. Since the width of the ball-gathering gap is smaller than the diameter of the tennis ball, the tennis ball cannot fall into the ball-gathering gap. Under the drive of the ball-gathering plate 8, the tennis ball moves along the ball-gathering gap towards the lifting tube 7.

[0024] The lower part of the lifting tube 7 is provided with a ball inlet, and the upper part is provided with a ball outlet 18. In order to facilitate the change of the tennis ball's movement direction from horizontal to vertical, an arc-shaped lifting part 17 is provided at the lower part of the ball inlet corresponding to the ball gathering gap. The width of the lifting tube 7 is adapted to the diameter of the tennis ball to prevent the tennis ball from falling into the lifting tube 7. An observation groove 13 is opened on the side of the lifting tube 7 facing the chain 4 to facilitate the observation of the tennis ball in the lifting tube 7 in case of malfunctions or other problems.

[0025] In this embodiment, the ball-gathering plate 8 is set at an angle on one side of the chain 4, and the angle between the ball-gathering plate 8 and the conveying direction of the chain 4 is an obtuse angle. This allows the tennis ball inside the lifting tube 7 to be lifted and protected by the support of the side wall of the lifting tube 7 and the bottom support of the ball-gathering plate 8, thus preventing the tennis ball from being stuck between the ball-gathering plate 8 and the side wall of the lifting tube 7 during the lifting process.

[0026] In this embodiment, one end of the guide groove 9 is located below the ball outlet 18, and the bottom of one end of the guide groove 9 is provided with a running slot 11 corresponding to the ball gathering plate 8. Since there are a total of three driving gears 16 and driven gears, the chain 4 is approximately triangular in shape. After passing the first driven gear 12, the chain 4 and the ball gathering plate 8 will directly change from an upward movement direction to a downward movement direction. At this time, the ball gathering plate 8, which changes its movement direction, pushes the tennis ball from the ball outlet 18 of the lifting tube 7 to the guide groove 9. Since the end of the guide groove 9 is located below the ball outlet 18, the ball gathering plate 8 moves downward through the running slot 11 to avoid motion interference with the guide groove 9.

[0027] Preferably, for tennis balls that fall outside the ball collection box 1, the other end of the guide plate 3 is provided with a slope 14. In this embodiment, the front side panel of the ball collection box 1 can be entirely made of a flexible curtain 21. Only the upper end of the curtain 21 is fixed. Since the bottom of the ball collection box is an inclined slope, tennis balls that fall into the bottom of the ball collection box will bounce away from the curtain 21 due to the slope. Therefore, they will not pass through the curtain 21 and fall outside the ball collection box. For tennis balls that fall directly from the curtain onto the curtain 21, some will fall to the bottom of the ball collection box and roll away from the curtain, while others may pass through the curtain 21 and fall outside the ball collection box. Since the flexible curtain dissipates the force of the tennis balls, most of the tennis balls that fall from the curtain will fall directly to the bottom of the ball collection box. Only a few balls will occasionally hit the curtain 21. Therefore, using the curtain 21 will not affect the ball dropping effect, but it will be more convenient to push the ball from the outside into the box. On-site staff can use tools with strip scrapers to collect the tennis balls that have fallen to the ground in large quantities and bring them to the front and back of the ball collection box 1. They can then push the balls into the ball collection box 1 via the slope 14, thus avoiding the need to pick up the tennis balls one by one and improving the convenience and efficiency of ball collection.

[0028] A tennis training device includes a ball machine 2, a ball collection box 1, and a screen 6. The ball machine 2 is installed inside the ball collection box 1, and the screen 6 is installed above the ball collection box 1. The ball collection box 1 is provided with a ball collection structure, which uses the ball collection structure of any of the tennis training devices described above.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
