Description

Technical Field

[0001] This utility model belongs to the technical field of sports training equipment, specifically a badminton serve training device. Background Technology

[0002] When training students, badminton coaches need to take a shuttlecock and serve it to a predetermined location with a racket. Then, they need to take another shuttlecock and serve it to the same predetermined location. To increase the serving frequency, there is a shuttlecock serving device in the existing technology, such as the published technical document "CN 108499078 A, Badminton Shuttlecock Serving Tube". According to the description, the method of use is as follows: when the serving tube is carried diagonally behind the back, the shuttlecocks will fall down due to gravity. However, because the diameter of the tube outlet is smaller than the diameter of the tail of the shuttlecock, the tail of the first shuttlecock is blocked by the tube outlet, and the front of the shuttlecock is exposed. The coach can then take the shuttlecock out by hand.

[0003] However, the serving tube is cylindrical, which causes significant movement during the serve, making the tube wobble and altering the outlet position, making it difficult to retrieve the ball. Additionally, its large overall size requires considerable space when not in use. Utility Model Content

[0004] The purpose of this invention is to provide a badminton serve training device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A badminton serving trainer includes a cylinder with a channel for moving a badminton shuttlecock inside. A fixing part is provided on the outside of the cylinder. The upper and lower ends of the cylinder are respectively provided with an inlet and an outlet, and the outlet diameter is smaller than the inlet diameter.

[0007] The cylindrical body is foldable and can be stored in an arc shape, so that the outer wall of the cylinder is close to the back of the human body, the inlet is close to the shoulder, and the outlet is close to the waist.

[0008] In a further technical solution, the aperture of the channel gradually decreases from the inlet to the outlet.

[0009] In a further technical solution, an end cap is provided at the entrance.

[0010] In a further technical solution, the cylinder includes at least two curved cylinders, namely cylinder one and cylinder two, which are sleeved on the outer periphery of cylinder two, and the outer diameter of cylinder two is larger than the diameter of the opening at the lower end of cylinder one.

[0011] In a further technical solution, the number of cylinders is four that are sequentially interlocked.

[0012] In a further technical solution, the outlet contracts inward along the circumference direction to form a limiting part.

[0013] In a further technical solution, the length of the cylinder is 60cm-80cm, and the bending angle of the cylinder is 30°-60°.

[0014] The beneficial effects of this utility model are:

[0015] Users can hold the racket with one hand and use the other hand to grab the end of the shuttlecock near their waist. With a little force, the shuttlecock can be pulled out. The next shuttlecock will automatically slide down to the exit under gravity and wait to be retrieved, improving serving efficiency. The curved design of the tube is more in line with the human back and requires less force to pull out the shuttlecock. This prevents the tube from shifting and keeps it in the initial position for a long time, reducing the number of times the tube needs to be adjusted, making it more efficient for users. In addition, when not in use, the whole unit can be folded up for storage, saving space.

[0016] Other features and advantages of this invention will be described in detail in the following detailed description section. Attached Figure Description

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please refer to Figure 1-4 ;

[0024] The badminton serving trainer described in this utility model has a storage function and is easy to carry. Specifically, it includes a cylinder 1, a channel 2 for moving badminton shuttlecocks is provided inside the cylinder 1, a fixing part 3 is provided on the outside of the cylinder 1, and an inlet 4 and an outlet 5 are respectively provided at the upper and lower ends of the cylinder 1. The diameter of the outlet 5 is smaller than the diameter of the inlet 4.

[0025] Before use, several shuttlecocks are placed into channel 2 in sequence. Although the inner diameter of channel 2 gradually decreases from inlet 4 to outlet 5, the width of channel 2 must at least ensure that the shuttlecocks can fall unimpeded to outlet 5. The diameter of the outlet 5 is smaller than the largest diameter of the shuttlecock. Therefore, after the shuttlecock falls to outlet 5, its end will protrude from outlet 5, and the feather support part will be stuck at outlet 5. The fixing part 3 in this embodiment can take many forms, including two hanging holes used in conjunction with a hanging rope, or a hook that can be hung on the user's shoulder. Therefore, the mechanism of fixing part 3 is not limited. The fixing part 3 allows the user to carry the shuttlecock vertically or at an angle. In this case, the outlet 5 end is located at the bottom. The inlet 4 is located at the top. In this embodiment, the cylinder 1 is curved in an arc, so that the outer wall of the cylinder 1 is close to the back of the human body. The inlet 4 is located near the shoulder of the human body, and the outlet 5 is located near the waist. At this time, the user can hold the racket with one hand and only need to hold the end of the shuttlecock with the other hand near the waist. With a little force, the shuttlecock can be pulled out. The next shuttlecock will automatically slide down to the outlet under the action of gravity and wait to be taken out, which improves the serving efficiency. The arc design of the cylinder 1 is more in line with the design of the human back, and the shuttlecock can be pulled out without too much force. It can prevent the cylinder 1 from shifting and keep it in the initial position for a long time, reducing the number of times the position of the cylinder 1 needs to be adjusted, making it more efficient for the user.

[0026] In addition, the cylinder 1 adopts a retractable design. One storage method is listed here. For example, the two ends of the cylinder 1 are respectively equipped with fixing rings, and the middle part adopts the design of "CN216469155U, a foldable storage plastic bucket" or "CN202657545U, a foldable storage bucket". Of course, the inner wall of the cylinder 1 is smooth, and the whole can be compressed and stored when not in use, without taking up space.

[0027] In this embodiment, the diameter of the channel 2 gradually decreases from the inlet 4 to the outlet 5, which allows the shuttlecock to gradually return to the center of gravity during its fall, maintaining a stacked state and preventing it from getting stuck. In addition, the length of the cylinder 1 is 60cm-80cm, and the bending angle of the cylinder 1 is 30°-60°.

[0028] Another embodiment of the folding method of the cylindrical body 1 of this utility model specifically includes at least two curved cylindrical bodies 1, namely cylindrical body 1a and cylindrical body 2a. Cylindrical body 1a is fitted around the outer periphery of cylindrical body 2a. The outer diameter of cylindrical body 2a is larger than the diameter of the opening at the lower end of cylindrical body 1a. However, when it needs to be unfolded, it is only necessary to place it vertically downwards. Under the action of gravity, cylindrical body 2a will naturally fall. When cylindrical body 2a reaches the lower opening of cylindrical body 1a, it will be stuck and cannot fall further downwards. At this time, the unfolding is completed. When it needs to be stored, it is only necessary to push cylindrical body 2a into cylindrical body 1a. It should be noted that the overall inner diameter width of cylindrical body 1a is larger than the outer diameter width of cylindrical body 2a.

[0029] Preferably, there are four cylinders, namely cylinder one 1a, cylinder two 2a, cylinder three 3a and cylinder four 4a, which are sequentially connected by the difference in aperture. The specific unfolding and storage method can refer to the above implementation process. In addition, regarding the gradual narrowing of the formed channel 2, it can be achieved by gradually narrowing the inner diameter of each section of the cylinder. In addition, the outlet 5 narrows inward along the circumference to form a limiting part 6, which can better hold the badminton shuttlecock. In addition, an end cap 7 is provided at the inlet 4. When several cylinders are in the storage state, the inlet 4 is closed by the end cap 7 to prevent other smaller cylinders from falling out of the inlet 4.

[0030] The cylinder used in this embodiment is made of plastic, which is very convenient for both assembly and production.

[0031] 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.

[0032] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
