Description

Technical Field

[0001] This utility model relates to the field of sports training auxiliary equipment technology, specifically to a ball return device for basketball training, and more specifically, to a basketball ball return auxiliary device with adjustable return direction, suitable for ball collection and guidance during basketball shooting training. Background Technology

[0002] In basketball training, repeated shooting practice is a key element in improving shooting stability and accuracy. Standing shooting (shooting from a fixed position) is one of the fundamental skills. Because the basketball needs to be retrieved after each shot, it places a significant burden on trainees, usually requiring dedicated personnel for retrieving and passing the ball, which increases training costs and difficulty. To address this issue, various automated ball return devices have emerged on the market to return the basketball to the athlete. However, existing automated ball return devices are typically complex in structure, inconvenient to install, and lack flexibility in adjusting the return angle, making accurate ball return difficult. To address these problems, existing technology CN210009601U discloses a "360-degree shooting fixed-point return training device." This device includes a suspension frame, multiple hanging ears, hanging ropes and hooks, and multiple sliding connectors (including left and right connectors) slidably connected to the suspension frame. The left connector has an I-shaped locking block at its lower end, and the lower ends of multiple sliding connectors are each connected to four return plates. These return plates interlock with each other and are arranged in a grid pattern. After the device is assembled, when a basketball is thrown into the basket, it will move along the return plates to the trainee's position, achieving a 360° return.

[0003] While existing ball return devices have addressed ball return issues during training to some extent, they still have shortcomings, including but not limited to:

[0004] First, the return path control is not stable and precise enough. Existing devices generally rely on a fixed-shape return surface for ball return, making the control of the return path relatively simple. In actual use, the ball may deviate from the predetermined direction due to impact angle, speed, or device vibration, making it difficult to maintain a precise and stable return path. The return path structure is a splicing and snap-fit ​​type, with the return path of this device consisting of four independent return plates that are interlocked. This segmented structure is prone to component detachment or misalignment during use. Once the return plates detach or are misaligned, it will cause discontinuity in the return path, thereby affecting the return efficiency and training continuity.

[0005] Secondly, the lack of multi-dimensional adjustment capabilities prevents it from fully adapting to diverse training needs. The existing adjustment mechanism is limited to sliding the return plate; the current return device can only adjust the return direction by moving the return plate up and down via left-right sliding connectors. This limited adjustment dimension makes it difficult to make targeted adjustments for different shooting angles, shooting distances, or specific training scenarios (such as free throws and three-point shots). Furthermore, the lack of a multi-axis linkage adjustment mechanism prevents flexible changes to the return direction and tilt angle. Trainees cannot finely adjust the return angle according to actual needs, limiting the diversity and relevance of training.

[0006] Third, it mainly relies on hook-type suspension. Existing devices use ropes and hooks to suspend the ball return device on the basket. This hook-type structure is dependent on the size and structure of the basket, has poor adaptability, and is not compatible with different models of baskets. At the same time, the single suspension method makes the device unstable after installation, and it is prone to shaking due to vibration during training, thus affecting the safety of use.

[0007] Fourth, the existing device has a non-closed ball return path design. Because the ball return device is assembled by snap-fit ​​parts, it does not form a closed ball return channel and lacks a continuous guide track and anti-drop protection. Once the basketball encounters gaps in the splicing or external interference during the return process, it is easy to deviate from the predetermined trajectory or leave the return path, which cannot guarantee the reliability and safety of the ball return. Utility Model Content

[0008] To address the aforementioned problems, this utility model provides a ball return device for basketball training, comprising:

[0009] A detachable fixing mechanism is used to adapt and install the device on basketball hoops of different sizes or their auxiliary support structures, and provides multi-dimensional adjustment functions;

[0010] A ball-guiding component is located below the basketball hoop and is configured to receive the basketball after a shot and concentrate its trajectory through a convergent structure.

[0011] The dynamic return component, connected to the ball-collecting guide component, includes at least one continuous streamlined path guiding structure, which guides the basketball to automatically return to the user area in a preset direction by gravity or inertia.

[0012] A direction control component, integrated into the dynamic feedback component, is used to dynamically adjust the spatial orientation and feedback angle of the path guidance structure according to training requirements.

[0013] The streamlined structure of the path guidance structure, combined with the multi-axis synergistic effect of the direction control component, enables the basketball to maintain continuous movement without jamming during the return pass. The detachable fixing mechanism is compatible with various basketball hoop structures through quick locking and height adaptation mechanisms.

[0014] Preferably, the detachable fixing mechanism includes a rotary locking assembly, which comprises a U-shaped clamp and a swivel support. The inner end of the U-shaped clamp has a groove that fits onto the basketball hoop. Both ends of the U-shaped clamp have clearance holes, and the swivel support passes through these clearance holes. The swivel support is a locking screw. This rotary locking connection mechanism allows for quick positioning and locking of components simply by rotating them into place. Compared to traditional bolt connections or sliding buckles, the rotary locking structure is simple to operate, provides a secure lock, and effectively prevents loosening and detachment during use, thereby improving the overall reliability and installation efficiency of the device.

[0015] Preferably, the ball-collecting guide component is a tapered flow-guiding cavity structure, including multiple angle-adjusting rods. The angle-adjusting rods are located on one side of the U-shaped clamp, and each rod has a threaded limiting groove at its top. The swivel support passes through a clearance hole and extends into the threaded limiting groove, thereby locking the detachable fixing mechanism onto the basketball hoop. The lower end of the angle-adjusting rod is fixedly positioned within the groove of the U-shaped sliding piece. The U-shaped sliding piece fits against the side end of the swivel positioning piece. Another locking screw passes through the limiting groove on both the U-shaped sliding piece and the swivel positioning piece, thus fixing the U-shaped sliding piece and the swivel positioning piece. A swivel ring is fixedly connected to the lower end of the swivel positioning piece. The tapered flow-guiding cavity, with its gradually converging design, effectively guides the basketball's smooth movement; simultaneously, the angle adjustment rods allow for adjustment of the flow-guiding cavity's tilt angle as needed. This combined structure can control the basketball's rolling speed and change the direction of return, achieving more precise ball return control; regardless of the shooting force, it can provide a suitable cushioning effect, thereby improving the controllability and stability of the return process.

[0016] Preferably, the path guiding structure includes a set of symmetrically arranged arc-shaped tracks, one end of which is fixedly connected to a guide track to form a closed track. A path guiding groove is formed between the arc-shaped tracks and the guide tracks. By combining the arc-shaped rotary tracks and the straight guide tracks, a completely closed return path is constructed. This closed path ensures that the basketball will not derail or fall during the return process, making the return process continuous and reliable. Compared to the open or discontinuous paths in the prior art, the closed return path structure of this invention significantly enhances the safety and stability of the return process.

[0017] Preferably, the direction control component includes a support connecting unit fixedly mounted on the side end of the rotating ring, the other end of which is connected to an anti-detachment guard structure. The anti-detachment guard structure is located at the center of the lower end of the rotating ring, with both ends abutting against the arc-shaped track. This direction control component serves both guiding and supporting functions. The support connecting unit provides robust support for the return track, while the anti-detachment guard structure effectively prevents the basketball from accidentally leaving the track during high-speed sliding. The combination of these components makes the basketball's return direction more controllable and its trajectory more stable, significantly improving the predictability of the return and overall safety.

[0018] Preferably, the support connection unit has a bent structure, including a limiting block fixedly disposed on the side end of the rotating ring. A support block is fixedly connected to the lower end of the limiting block, and a bent bearing block is fixedly connected to the end of the support block away from the limiting block. A locking frame is fixedly connected to the end of the bent bearing block away from the support block. By designing a bent support connection structure for the corner of the return track, additional support and buffering are provided at the bend. This structure smooths the transition at track corners, reduces the impact and friction of the basketball at the turning point, and enhances the structural strength of the curved section, effectively improving the durability of the device during use.

[0019] Preferably, the anti-detachment baffle structure includes a positioning connecting block, which is disposed on and fixedly connected to the upper end of the locking frame. Both ends of the positioning connecting block are fixedly connected to a direction-adjustable anti-detachment baffle. Each direction-adjustable anti-detachment baffle includes a longitudinally arranged triangular stop section, with a diagonally extending square stop section fixedly disposed at the upper end of the triangular stop section. By setting the anti-detachment baffle at the end of the return track and tightly integrating it with the end structure of the track, a protective tail end is formed. This design prevents the basketball from flying out of the track due to inertia at the return end point, ensuring that the basketball is completely recovered and returns to the starting position. Compared to the potential ball escape situation in existing technologies, the anti-detachment baffle structure of this invention significantly improves the reliability of the equipment.

[0020] Preferably, a slotted clamp is fixedly provided on the side of the triangular stop section away from the positioning connecting block. The slotted clamp is clamped onto the arc-shaped track, and the slotted clamp structure is used to fix the return assembly. The clamp fits tightly with the track and the bracket. A rigid connection between the components is achieved through adjustable slots and bolt fastening, preventing loosening or displacement after installation. Compared with ordinary connectors, the slotted clamp structure ensures the overall stability and accuracy of the device connection and extends its service life.

[0021] Preferably, both the triangular and square retaining sections have an anti-rebound coating on their inner walls, preferably a silicone PU coating. This anti-rebound material, applied to the return track surface, effectively absorbs the rebound energy generated when the basketball contacts the track. This coating makes the basketball roll more smoothly and the return trajectory more controllable, suppressing random deviations and significantly improving the accuracy and consistency of the return, meeting the quality requirements of high-intensity training.

[0022] Compared with the prior art, the present invention achieves the following beneficial technical effects:

[0023] This invention, through a closed return track and a smooth guiding structure, enables the basketball to glide continuously and smoothly along a preset path. Compared with the open or uneven return channels in existing technologies, it achieves stable and continuous closed control of the return path. The basketball is always guided by the closed channel during the return process and will not deviate or fall off due to splicing of sections, which greatly improves the continuity and reliability of the return process. In addition, it reduces basketball deviation and jamming, effectively avoiding deviation and jamming of the basketball during the return process due to discontinuous path, ensuring the continuity and stability of the return, and thus significantly improving the continuity and safety of the training process.

[0024] This invention introduces a feature into the ball return mechanism that allows for flexible adjustment of the return direction and tilt angle along multiple axes. Trainees can simultaneously change the horizontal direction and vertical tilt angle of the return ball according to their needs, achieving precise returns from multiple angles and directions. This significantly improves the flexibility and diversity of training, meeting the needs of different training objectives.

[0025] This invention features a multi-degree-of-freedom linkage adjustment mechanism, including an adjustable angle adjustment rod and a rotating connector, allowing for flexible adjustment of the ball trajectory angle and direction in multiple degrees of freedom. This enables rapid changes in the return ball angle for shooting practice at different distances and directions. Trainees can simultaneously adjust the horizontal direction and vertical tilt angle of the return ball as needed. Compared to existing technologies, this invention significantly improves the diversity and adaptability of training, meeting the needs of different training scenarios. It achieves multi-dimensional adjustment capabilities for the return ball angle and direction, satisfying diverse training situations.

[0026] This invention improves the connection method between the device and the basketball hoop, providing a more compatible and stable fixing solution. The device can adopt a detachable fixing mechanism compatible with different basketball hoop sizes, allowing the ball return device to be firmly fixed to various basketball hoops, maintaining high stability during installation and use. The detachable fixing mechanism prevents shaking and loosening during training, improving the overall installation reliability and the device's applicability.

[0027] This invention forms a closed, continuous ball-guiding channel and incorporates an anti-drop structure on the direction control component to ensure the basketball moves along a predetermined trajectory without deviating throughout the entire return process. The basketball is constrained and guided throughout the return process, effectively preventing drop or deviation caused by path interruptions, thereby improving the safety and efficiency of the training process.

Detailed Implementation

[0033] The present invention will be further explained below with reference to the accompanying drawings and embodiments.

[0034] Reference Figures 1-4 As shown, this utility model provides a ball return device for basketball training, comprising:

[0035] A detachable fixing mechanism 1 is used to adapt and install the device on basketball hoops of different sizes or their auxiliary support structures, and provides multi-dimensional adjustment functions;

[0036] The ball-collecting guide component 2 is located below the basketball hoop and is configured to receive the basketball falling after the shot and concentrate the basketball's trajectory through a convergent structure.

[0037] The dynamic return component 3 is connected to the ball collecting and guiding component 2 and includes at least one continuous streamlined path guiding structure 31, which guides the basketball to automatically return to the user area in a preset direction by gravity or inertia.

[0038] The orientation control component 4 is integrated into the dynamic feedback component 3 and is used to dynamically adjust the spatial orientation and feedback angle of the path guidance structure 31 according to training requirements.

[0039] The streamlined structure of the path guidance structure 31, combined with the multi-axis collaborative action of the direction control component 4, enables the basketball to maintain continuous movement without jamming during the return pass. The detachable fixing mechanism 1 is compatible with various basketball hoop structures through a quick locking and height adaptation mechanism.

[0040] The detachable fixing mechanism 1 includes a rotary locking assembly 10, which includes a U-shaped clamp 101 and a swivel support 102. The clamping groove 103 at the inner end of the U-shaped clamp 101 is fitted onto the basketball hoop. Both ends of the U-shaped clamp 101 have clearance holes 104, and the swivel support 102 passes through the clearance holes 104. The swivel support 102 is a locking screw. The rotary locking assembly 10 is used for quick fixing of the device. The clamping groove 103 of the U-shaped clamp 101 is aligned with the edge of the basketball hoop and inserted, so that the basketball hoop is embedded in the clamping groove 103. The locking screw of the swivel support 102 passes through the clearance holes 104 at both ends of the U-shaped clamp 101 and is screwed into the threaded limiting groove 202 at the top of the angle adjusting rod 201. The swivel support 102 is rotated clockwise until locked. At this point, the U-shaped clamp 101 is tightly fitted to the basketball hoop, completing the initial fixing of the device.

[0041] The ball-collecting guide component 2 is a tapered flow-guiding cavity structure, including multiple angle adjustment rods 201. The angle adjustment rods 201 are located on one side of the U-shaped clamp 101. The top of the angle adjustment rods 201 is provided with a threaded limiting groove 202. The swivel support 102 passes through the clearance hole 104 and extends into the threaded limiting groove 202 to lock the detachable fixing mechanism 1 onto the basketball hoop. The lower end of the angle adjustment rods 201 is fixedly located in the slot of the U-shaped sliding piece 203. The U-shaped sliding piece 203 is attached to the side end of the swivel positioning piece 204. Another locking screw passes through the limiting groove on the U-shaped sliding piece 203 and the swivel positioning piece 204 to fix the U-shaped sliding piece 203 and the swivel positioning piece 204. The lower end of the swivel positioning piece 204 is fixedly connected to a swivel ring 205.

[0042] The tapered flow channel structure guides the basketball to fall in a concentrated manner. The lower end of the angle adjustment rod 201 is inserted into the slot of the U-shaped sliding plate 203, and is fixed by another locking screw passing through the limiting groove of the U-shaped sliding plate 203 and the rotating positioning plate 204. Loosen the locking screw of the U-shaped sliding plate 203; slide the U-shaped sliding plate 203 along the rotating positioning plate 204 to change the tilt angle of the angle adjustment rod 201; tighten the screw to fix the tilt angle of the flow channel to adapt to different shooting forces and landing positions. The rotating ring 205 at the lower end of the rotating positioning plate 204 connects to the dynamic return component 3, forming a transition channel for the basketball from collection to return.

[0043] The path guiding structure 31 includes a set of symmetrically arranged arc-shaped tracks 310. Each arc-shaped track 310 has a guide track 311 fixedly connected to one end, forming a closed track. A path guiding groove 312 is formed between the arc-shaped tracks 310 and the guide tracks 311. After the basketball falls into the path guiding groove 312 via the ball-collecting guide component 2, it slides smoothly along the streamlined track under gravity, avoiding jamming or derailment. By combining the arc-shaped rotary track and the straight guide track, a completely closed return path is constructed. This closed path ensures that the basketball will not derail or fall during the return process, making the return process continuous and reliable. Compared to the open or discontinuous paths in the prior art, the closed return path structure of this invention significantly enhances the safety and stability of the return process.

[0044] The direction control component 4 includes a support connection unit 40 fixedly mounted on the side of the rotating ring 205. The support connection unit 40 provides structural stability, and its other end is connected to the anti-detachment side guard structure 41. The anti-detachment side guard structure 41 ensures the safety of the return ball's endpoint. The anti-detachment side guard structure 41 is located at the center of the lower end of the rotating ring 205, and its two ends abut against the arc-shaped track 310. The direction control component 4 is provided, serving both guiding and supporting functions. The support connection unit provides robust support for the return track, while the anti-detachment side guard structure effectively prevents the basketball from accidentally leaving the track during high-speed sliding. The cooperation of this component makes the basketball's return direction more controllable and the trajectory more stable, significantly improving the predictability of the return ball and overall safety.

[0045] The support connection unit 40 has a bent structure, including a limiting block 401, which is fixedly mounted on the side of the hanging ring 205. A support block 402 is fixedly connected to the lower end of the limiting block 401. A bent bearing block 403 is fixedly connected to the end of the support block 402 away from the limiting block 401, and a locking frame 404 is fixedly connected to the end of the bent bearing block 403 away from the support block 402. By designing a bent support connection structure for the corner of the return track, additional support and cushioning are provided at the bend. This structure smooths the transition at track corners, reduces the impact and friction of the basketball at the turn, and enhances the structural strength of the curved section, effectively improving the durability of the device during use.

[0046] The anti-detachment baffle structure 41 includes a positioning connecting block 410, which is disposed on and fixedly connected to the upper end of the locking frame 404. Both ends of the positioning connecting block 410 are fixedly connected to direction-adjustable anti-detachment baffles 411. Each direction-adjustable anti-detachment baffle 411 includes a longitudinally arranged triangular stop section 412, and an obliquely extending square stop section 413 is fixedly disposed at the upper end of the triangular stop section 412. By setting the anti-detachment baffle at the end of the return guide rail and tightly integrating it with the end structure of the guide rail, a protective tail end is formed. This design prevents the basketball from flying out of the track or leaving the track due to inertia at the return end point, ensuring that the basketball is completely recovered and returns to the starting position. Compared with the possibility of the ball escaping during return in existing technologies, the anti-detachment baffle structure of this utility model significantly improves the reliability of the equipment.

[0047] A slotted clamping plate 414 is fixedly installed on the side of the triangular stop section 412 away from the positioning connecting block 410. The slotted clamping plate 414 is clamped onto the arc-shaped track 310. The slotted clamping plate structure is used to fix the return assembly, and the clamping plate fits tightly with the track and the bracket. A rigid connection between the components is achieved through adjustable slots and bolt fastening, preventing loosening or displacement after installation. Compared with ordinary connecting parts, the slotted clamping plate structure ensures the overall stability and accuracy of the device connection and extends its service life.

[0048] Both the triangular stop section 412 and the square stop section 413 have an anti-rebound coating 415 on their inner walls, preferably a silicone PU coating. This anti-rebound material, applied to the return track surface, effectively absorbs the rebound energy generated when the basketball contacts the track. This coating makes the basketball roll more smoothly and the return trajectory more controllable, suppressing random deviations and significantly improving the accuracy and consistency of the return, meeting the quality requirements of high-intensity training.

[0049] To facilitate understanding of the above technical solutions of this utility model, the following detailed description of the above technical solutions of this utility model is provided through specific usage methods.

[0050] The specific working process is as follows: During shooting training, after the basketball hits the hoop, it falls through the hoop and enters the top opening of the ball-collecting guide component 2 of this device. Under the action of gravity, the basketball slides downward along the tapered cavity formed by the angle adjustment rod 201 of the ball-collecting guide component 2. After the basketball slides down from the hanging ring 205 at the bottom of the ball-collecting guide component 2, it hits the silicon PU coated baffle of the anti-detachment baffle structure 41 of the direction control component 4. The energy is absorbed, preventing significant rebound. Under the action of the ramp, the basketball rolls obliquely downward along the path guide groove formed by the arc track 310 and the guide track 311 of the path guide structure 31, rolling out from under the device in a controlled manner and returning to the trainee's original position or designated position. The entire return process is smooth and reliable, and the ball will not jump out or roll to an unwanted position. After training, the fixing mechanism 1 can be undone to quickly disassemble the device for easy storage and transportation.
