Description

Badminton with replaceable feathers

The present invention relates to badminton, badminton or similar balls for feathers with feathers, and more particularly to badminton with replaceable wings.

Say

Background technique

At present, most of the badminton used on the market does not have the replacement function, that is, as long as one feather is damaged, the whole badminton can not be used normally, so the waste is huge and environmental pollution is caused. Although the relevant information also has the information of the badminton exchangeable, In the specific use, it is easy to cause damage to the ball head, and the fixing frame is easily damaged. Summary of the invention

SUMMARY OF THE INVENTION It is an object of the present invention to provide an improved badminton shuttlecock that can be replaced with feathers to improve the durability of the shuttlecock of the replaceable feather during use, particularly the durability of the ball portion.

The technical solution adopted by the present invention is as follows: It comprises a ball carrier, a fixing seat, a feather frame and a feather wing which are sequentially connected to the base, and a cushion pad is arranged between the ball holder and the fixing seat, and the bottom of the feather frame is opened. Pressure relief hole.

As a modification of the present invention, the number of the pressure reduction holes is three or more.

As a modification of the present invention, the material of the cushion is fiber or rubber. In order to make the badminton in the damage of the feather wing, it can be replaced by the single tube, and the replaced wing fin is more firm and repurposed. According to another modification of the present invention, the feather frame is formed by the upper fixing ring being connected to the support bar, the reinforcing ring and the lower fixing ring, and the upper fixing ring is provided with a socket.

In addition, the upper fixing ring can also be provided with a plurality of flanges, and the insertion holes are located on the flange. As a preferred solution of the above solution, the upper flange and the center of the upper fixing ring are convex. The angle of the edge is 45 - 1 35 degrees.

As a preferred solution of the above solution, the angle between the central axes of any two of the jacks symmetrical according to the center axis of the badminton on the upper fixing ring is 45 to 1 35 degrees.

As a preferred embodiment of the above aspect, the number of the flanges is 16.

As a preferred solution of the above solution, the lower fixing ring has a lower insertion hole and a feather frame external thread, the fixing seat on the fixing seat has an internal thread, and the external thread of the feather frame is connected with the internal thread of the fixing seat on the fixing seat. .

As a preferred solution of the above solution, a fixing seat internal thread, a fixing seat positioning bolt and a feather wing positioning hole are formed on the fixing base; and the fixing seat positioning bolt is connected with the ball holder positioning hole on the ball holder; the feather wing positioning hole and the feather The bottoms of the fins are connected at the bottom.

As a preferred solution of the above scheme, a burr is formed at the bottom of the pin of the feather wing, and the burr is located at any position from the bottom of the plunger at 0 to 1.5 cm.

As a further preferred embodiment of the above aspect, burrs are formed at the bottom of the feathered fins at 0 to 1.5 cm.

5毫米。 The length of the burr is 0. 7-1.5 mm. The invention has the following advantages: 1. The invention has a pressure reducing hole on the bottom of the feather frame, and the function is to adjust the instantaneous high pressure generated by the badminton during the hitting process through the pressure reducing hole to avoid continuous high pressure and high temperature. The situation that the ball holder and the fixed seat are separated can meet the requirement of prolonging the service life of the badminton; 2. The invention is provided with a cushion between the ball holder and the fixed seat, and the function thereof is to enhance the fastening of the whole ball head, so that the badminton is The support force of the ball holder during the striking process can be buffered by the cushion pad, the tightness of the overall ball head is strengthened, and the instantaneous impulse is buffered to avoid the technical problem that the ball holder is too thin and brittle.

The beneficial effects of the technical improvement of the ball rack of the present invention are as follows: 1. The invention designs the badminton into a detachable assembly manner, so that the single feather wing can be replaced in the field when it is damaged, which is beneficial to the repeated use of the product and saves the cost; 2. According to the invention, since the badminton wings are inserted, the feather thorns left in the insertion portion of the feathers serve as a barbed locking function for filling the jacks and reinforcing the feathers, so that the feathers are more firmly fixed at the feathers. On the feather stand; 3. The invention adopts the flange locking technology, and the positioning of the feather is stabilized by the self-elastic tension of the flange material, so that the flight performance of the badminton is more stable; 4. The flange of the invention is independent. The individual design makes the badminton less affected by the wind resistance during flight, making it indistinguishable from the traditional badminton flight. 5. The feather frame part of the invention adopts an upright design to improve the resistance to hitting while reducing the wind resistance. The utility model has almost no difference between the practical hand feeling and the flying performance of the badminton. 6. The invention adopts the feather fixing method with a fixed angle, so that the technical requirements of the badminton production are greatly reduced, and the qualified rate of the finished product is improved; 7. The invention Thanks to the precise machining process and assembly process, a large number of skilled workers are saved, which effectively saves production costs. DRAWINGS
