[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] Example 1: As Figures 1-6 As shown, this utility model provides a portable badminton training auxiliary frame, including: a base 1, a hollow tube 3 disposed at the top center of the base 1, an inner rod 8 slidably connected to the inner surface of the hollow tube 3, a top rod 10 fixedly connected to the top of the inner rod 8, a fixing block 11 fixedly connected to the top of the top rod 10, an installation rod 12 fixedly connected to the outer surface of the fixing block 11, a second installation block 14 rotatably connected to the outer surface of the installation rod 12, a support rod 15 fixedly connected to the inner surface of the second installation block 14, and a fixing ring 16 fixedly connected to the outer surface of the support rod 15; a counterweight assembly 2, disposed on the outer surface of the hollow tube 3, the counterweight assembly 2 including an annular water tank 201, a water injection pipe 202 fixedly connected to the top of the annular water tank 201, and a screw thread on the outer surface of the water injection pipe 202. A sealing cap 203 is rotatably connected to the hollow tube 3. A first mounting block 6 is fixedly connected to the outer surface of the hollow tube 3 near the top. A second threaded rod 17 is rotatably connected to the inner surface of the first mounting block 6. The outer surface of the second threaded rod 17 rotatably penetrates the outer surface of the hollow tube 3 and extends inward. A throttle 7 is fixedly connected to the outer surface of the second threaded rod 17 away from the hollow tube 3. Multiple adjustment holes 9 are equidistantly opened on the outer surface of the inner rod 8. The multiple adjustment holes 9 are matched with the position of the second threaded rod 17. A wing nut 13 is rotatably connected to the outer surface of the mounting rod 12. The wing nut 13 is matched with the second mounting block 14. A first threaded rod 4 is fixedly connected to the bottom center of the hollow tube 3. The outer surface of the first threaded rod 4 is rotatably connected to the inner surface of the base 1.

[0027] The overall effect of Embodiment 1 is as follows: During badminton training, by placing the annular water tank 201 in the top circular groove of the base 1 and inserting the hollow tube 3 from top to bottom into the center hole of the annular water tank 201, the first threaded rod 4 is screwed into the base 1, which serves to fix it. The sealing cover 203 is opened, and water is injected into the annular water tank 201 through the water injection pipe 202. When the annular water tank 201 is full of water, the overall center of gravity of the training auxiliary frame will shift downward, ensuring stability during training. A badminton shuttlecock or training cloth is tied to the fixing ring 16 with a rope to fix and suspend the training target. Depending on the training height, the rear surface of the support rod 15 can be held to move the second mounting block 14 on the mounting rod 12. After the outer surface of the support rod 15 is rotated at a certain angle, the front end of the support rod 15 tilts upward, increasing the distance between the suspended target and the ground. Tighten the wing nut 13 so that when it is threaded with the mounting rod 12, it will clamp and fix the second mounting block 14 on the outer surface of the mounting rod 12. Rotate the handle 7 to move the second threaded rod 17 outward, so that the personnel can pull the inner rod 8 outward to adjust the height. This causes the inner rod 8 to pull the top rod 10 and the fixing block 11 fixed at the top to increase the distance from the ground. When the handle 7 is rotated in the opposite direction, the second threaded rod 17 is screwed into the inner thread of the first mounting block 6, so that it abuts against the corresponding adjustment hole 9, which plays a role in fixing the inner rod 8 and makes it convenient for personnel to conduct striking training on the suspended target.

[0028] Example 2: Figures 1-6 As shown, a circular groove is provided at the center of the top of the base 1. The outer surface of the annular water tank 201 is in contact with the inner surface of the circular groove near the bottom. A limiting hole 5 is provided at the top of the base 1 near the edge. The limiting hole 5 is matched with the support rod 15.

[0029] The effect achieved by the entire embodiment 2 is that, during use, by setting the annular water tank 201 in the circular groove at the top of the base 1, it plays a limiting role. By opening the limiting hole 5 at the top of the base 1, it is convenient to insert the vertically downward support rod 15 into the limiting hole 5 when the training auxiliary frame is stored, which plays a limiting role and prevents the support rod 15 from swinging and affecting the carrying when it is carried, thus making it highly practical.

[0030] Working principle: During badminton training, the annular water tank 201 is placed in the top circular groove of the base 1, and the hollow tube 3 is inserted from top to bottom into the center hole of the annular water tank 201, so that the first threaded rod 4 is screwed into the base 1, which plays a fixing role. The sealing cover 203 is opened, and water is injected into the annular water tank 201 through the water injection pipe 202. When the annular water tank 201 is full of water, the overall center of gravity of the training auxiliary frame will shift downward, ensuring the stability during training. The badminton shuttlecock or training cloth is tied to the fixing ring 16 with a rope to fix and suspend the training target. Depending on the training height, the rear surface of the support rod 15 can be held to drive the second mounting block 14 to rotate a certain angle on the outer surface of the mounting rod 12. After that, the front end of the support rod 15 tilts upward, increasing the distance between the suspended target and the ground. The wing nut 13 is tightened to make it threaded with the mounting rod 12. When tightened, the second mounting block 14 is clamped and fixed to the outer surface of the mounting rod 12. Rotating the handle 7 causes the second threaded rod 17 to move outward, making it convenient for personnel to pull the inner rod 8 outward to adjust the height. This causes the inner rod 8 to pull the top rod 10 and the fixing block 11 fixed at its top to separate from the ground. When the handle 7 is rotated in the opposite direction, the second threaded rod 17 is screwed into the inner thread of the first mounting block 6, so that it abuts against the corresponding adjustment hole 9, which serves to fix the inner rod 8. This makes it convenient for personnel to conduct striking training on the suspended target. By setting the annular water tank 201 in the circular groove at the top of the base 1, it serves as a limit. The limiting hole 5 opened at the top of the base 1 allows the vertically downward support rod 15 to be inserted into the limiting hole 5 when the training auxiliary frame is stored, which serves as a limit and prevents the support rod 15 from swinging and affecting carrying when carried. This makes it highly practical.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
