[0024] To enable those skilled in the art to better understand this utility model, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0025] The terminology used in this invention refers to those general terms currently widely used in the art in consideration of the functionality of this invention; however, these terms may vary according to the intent, precedent, or new technology of those skilled in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of this invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of this invention.

[0026] Example 1, referring to Figures 1-5 This embodiment provides a basketball training defensive device, including an angle adjustment mechanism 1, a device base 11, a first drive component 12 disposed on the device base 11, a rotating component 13 disposed on the device base 11 and the first drive component 12, a limiting component 14 disposed on the device base 11 and the rotating component 13, and a connecting rod 15 disposed on the device base 11.

[0027] The height adjustment mechanism 2 includes a second drive assembly 21 disposed on the connecting rod 15, a steering assembly 22 disposed on the second drive assembly 21, a lifting assembly 23 disposed on the connecting rod 15 and the steering assembly 22, and a defense dummy 24 disposed on the lifting assembly 23.

[0028] The first drive assembly 12 drives the rotating assembly 13 to run, the limiting assembly 14 is used to limit the movement of the rotating assembly 13, the second drive assembly 21 drives the steering assembly 22 to run, and the steering assembly 22 drives the lifting assembly 23 to run.

[0029] The first drive assembly 12 is fixed to the outside of the device base 11 and its output end is connected to the rotating assembly 13. The rotating assembly 13 and the limiting assembly 14 are arranged in the internal accommodating space of the device base 11. The connecting rod 15 is rotatably connected to the top of the device base 11 and passes through the top shell of the device base 11 to connect to the rotating assembly 13. The second drive assembly 21 is fixed to the outside of the connecting rod 15 and its output end is connected to the steering assembly 22. The steering assembly 22 and the lifting assembly 23 are engaged. The lifting assembly 23 is arranged inside the connecting rod 15 and its top extends out of the connecting rod 15 and is connected to the defense dummy 24.

[0030] In use, the rotating component 13 inside the base 11 of the first drive component 12 rotates. The rotating component 13 is fixedly connected to the connecting rod 15, so the defensive dummy 24 on the connecting rod 15 can be rotated, thereby flexibly adjusting the angle of the training defensive device. At the same time, the second drive component 21 drives the steering component 22 to rotate, and the steering component 22 drives the lifting component 23, so that the lifting component 23 can drive the defensive dummy 24 to rise and fall, thereby adjusting the training height of the training defensive device. It can be adapted to different training needs, effectively improving the practicality and versatility of the training device.

[0031] Furthermore, the connection form of the second threaded rod 231 is optimized by setting the steering component 22. Compared with the traditional single-end drive, where one end is connected to the motor and the other end is simply rotated to connect the connecting rod 15, this solution greatly increases stability. The steering component 22 allows the two ends of the second threaded rod 231 to be rotatably connected within the connecting rod 15, so that it can be evenly stressed when rotating, avoiding problems such as loosening and eccentricity caused by single-end stress, and can rotate accurately and stably even under high-intensity working conditions.

[0032] Example 2, refer to Figure 3 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a first drive component 12 including a first servo motor 121 disposed on the device base 11; wherein, the first servo motor 121 is fixed on the outside of the device base 11, and its output end is connected to a first threaded rod 131 inside the device base 11.

[0033] Furthermore, the rotating assembly 13 includes a first threaded rod 131 disposed within the device base 11, a first threaded slider 132 disposed on the first threaded rod 131, a connecting shaft 133 disposed within the device base 11, a rotating rod 134 disposed on the connecting shaft 133, and a rotation conversion groove 135 disposed on the first threaded slider 132 and the rotating rod 134; wherein, the first threaded rod 131 is horizontally rotatably connected to the inside of the device base 11, the first threaded slider 132 is threadedly connected to the first threaded rod 131, the device base 11 is vertically rotatably connected to the connecting shaft 133, the connecting shaft 133 is connected to the connecting rod 15 at the top of the device base 11 through a preset through hole, the rotating rod 134 is fixed along the shaft of the connecting shaft 133, the rotating rod 134 is provided with a vertical strip-shaped rotation conversion groove 135, and the support rod at the top of the first threaded slider 132 is slidably connected to the rotation conversion groove 135.

[0034] Furthermore, the limiting component 14 includes a slider limiting groove 141 disposed on the device base 11 and the rotating component 13; wherein, the slider limiting groove 141 is disposed on the side of the internal accommodating space of the device base 11 away from the rotation conversion groove 135 and parallel to the first threaded rod 131, and the end of the slider limiting groove 141 away from the rotation conversion groove 135 is slidably connected in the slider limiting groove 141.

[0035] In use, the first servo motor 121 drives the first threaded rod 131 to rotate, which in turn drives the threaded slider 132 to rotate. Since the first threaded slider 132 is restricted by the slider limiting groove 141, its rotational motion is converted into left-right translation on the first threaded rod 131. Simultaneously, the support rod at the top of the first threaded slider 132 can slide within the elongated rotation conversion groove 135, while the rotating rod 134 is mounted along the axis on the connecting shaft 133, which is vertically rotatably connected to the device base 11. Therefore, when the first threaded rod 131 rotates, it drives the connecting shaft 133 and its top-connected connecting rod 15 to rotate, ultimately achieving the rotational adjustment of the training angle of the defense dummy 24.

[0036] Example 3, referring to Figures 4-5 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a second drive assembly 21 including a second servo motor 211 disposed on the connecting rod 15; wherein, the second servo motor 211 is fixed on the outside of the connecting rod 15 and its output end is connected to the drive shaft 221.

[0037] Furthermore, the steering assembly 22 includes a drive shaft 221 disposed on the connecting rod 15 and the second servo motor 211, a first helical gear 222 disposed on the drive shaft 221, and a second helical gear 223 disposed on the lifting assembly 23; wherein, the drive shaft 221 is rotatably connected to the inner wall of the connecting rod 15, and the first helical gear 222 is provided at the end away from the second servo motor 211, the first helical gear 222 and the second helical gear 223 are meshed and connected, and the second helical gear 223 is mounted on the second threaded rod 231.

[0038] Furthermore, the lifting assembly 23 includes a second threaded rod 231 disposed within the connecting rod 15, a second threaded slider 232 disposed on the second threaded rod 231, and a lifting rod 233 disposed on the second threaded slider 232; wherein, the second threaded rod 231 is rotatably connected inside the connecting rod 15, the second threaded slider 232 is threadedly connected to the second threaded rod 231, the second threaded slider 232, and the lifting rod 233 is connected to the top of the second threaded slider 232.

[0039] Furthermore, two lifting rods 233 are provided and are located on both sides of the second threaded slider 232. The two lifting rods 233 are vertically arranged and slidably connected to the top housing of the connecting rod 15. A limiting through hole is pre-set at the junction of the lifting rod 233 and the connecting rod 15. Each lifting rod 233 is slidably connected in the limiting through hole and connected to the top defense dummy 24 through the limiting through hole. The size of the limiting through hole is equal to or slightly larger than the outer diameter of the connecting rod 15.

[0040] Furthermore, a limiting block 25 is provided inside the connecting rod 15 near the second helical gear 223; wherein, the limiting block 25 is fixed on the inner wall of the connecting rod 15, and the limiting block 25 is close to the second helical gear 223, and the position of the limiting block 25 is offset from that of the second threaded rod 231.

[0041] Furthermore, defensive manipulators 24 are rotatably connected to both sides of the defensive dummy 24; in particular, defensive manipulators 24 are rotatably connected to both shoulders of the defensive dummy 24.

[0042] In use, the second servo motor 211 drives the drive shaft 221 to rotate. The drive shaft 221 is equipped with a first helical gear 222, and the second threaded rod 231 is equipped with a second helical gear 223. Therefore, the rotation of the drive shaft 221 can drive the rotation of the second threaded rod 231. At the same time, the second threaded rod 231 is threadedly connected to the second threaded slider 232. The top of the second threaded slider 232 is equipped with two lifting rods 233, and both lifting rods 233 are slidably connected to the limiting through hole at the top of the connecting rod 15. Under the guiding and limiting effect of the limiting through hole, the stability and accuracy of the lifting process are ensured. Therefore, the rotation of the second threaded rod 231 can drive the second threaded slider 232 to move up and down smoothly, thereby driving the defensive dummy 24 above the connecting rod 15 to move up and down, and thus adjusting the training height of the training defense device.

[0043] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of this utility model.
