Description

Splicing three-section outdoor ball

Technical Field

The invention belongs to the technical field of cultural and sports articles, and particularly relates to a three-section type outdoor ball in splicing.

Background

The traditional badminton is characterized in that a plurality of pieces of feathers are inserted into a badminton head, then two coils are wound, and then glue is added for reinforcement. The feather is natural feather of goose and duck. In order to reduce the manufacturing cost, artificial feathers are also used. However, no matter what kind of mode is adopted, the existing badminton is mostly suitable for indoor use, which is determined by the structure of the badminton. Because the traditional badminton has larger blades and more support rods (generally 16 feathers are adopted), the wind shielding area of the side surface is larger. If the badminton shuttlecock is used outdoors, even if breeze exists, the flight route of the badminton shuttlecock can deviate, and the use feeling is seriously influenced.

The utility model patent No. 201520751206.8 discloses an outdoor badminton, adopts uncovered design in the middle of its bulb, reduces the influence of wind to ball route. Meanwhile, the tail wing (equivalent to feather) is of a non-coherent design, and an air flow channel is further increased. Although the wind resistance is reduced, the design of the existing badminton is completely changed, and the use feeling is not ideal.

The utility model with patent number 201120294210.8 discloses a windproof badminton, which comprises an elastic ball and feathers, wherein the elastic ball and the feathers are connected by a wire. The feather of this badminton does not adopt the circumference to enclose the mode of closing, has reduced the area of keeping out the wind greatly, has nevertheless changed the structure of badminton completely, and the use is felt not good, and the flight is also unstable.

The existing outdoor ball has a big defect only in the two-section structure of the integrally formed ball body and the ball head: the gravity center of the outdoor ball is excessively concentrated on the surface of the ball head and the ball champion, the waist parts of the outdoor ball and the ball champion are light in weight, the shearing effect of force is mainly concentrated on the waist part of the ball after being hit, the waist part of the outdoor ball with the two-section structure is thin and weak, and the mass of the waist part is excessively small, so that the gravity center of the outdoor ball is unstable, and the flying stability is poor.

Furthermore, the heights of the two curved surfaces of the two adjacent parts are different at the two sides close to the common support rib. The difference in height is in order to improve the windage dynamics of two adjacent curved surfaces to make the ball produce bigger rotation degree, the ball is faster at the rotation of flight in-process, and the ball is more stable, and is dynamic more sufficient.

Furthermore, two adjacent plug-in connection rods are connected through reinforcing ribs, and reinforcing ribs are arranged between two adjacent curved surface support ribs on the curved surface part of the spherical crown. The reinforcing ribs and the reinforcing ribs are arranged to reinforce the strength of the spherical crown and reduce the deformation of the spherical crown in the flying process of the ball.

Furthermore, the cross section of the supporting rod is V-shaped, Y-shaped, U-shaped, E-shaped, T-shaped or cross-shaped. The weight of the ball is reduced on the premise of ensuring the supporting strength.

Furthermore, two adjacent support bars are connected through the connecting rib. The function of the connecting rib is to prevent the support rod from shaking in flight.

Furthermore, the ball head is a segment body with the segment height larger than the radius of the ball, and the mounting groove and the segment body are the same central shaft. The ball cup is adopted, so that the contact area between a ball and the bat is increased, and the hitting angle is enlarged.

Further, the mounting part is cylindrical with a circular or regular polygon cross section; correspondingly, the mounting groove be with the ring channel of installation department shape and size matching, or the column groove of inner wall and installation department outer wall shape and size matching. The cylindrical mounting part is firmly inserted and connected, and the weight of the ball is reduced.

The novel badminton disclosed by the invention changes the structure that 16 pieces of feathers of the traditional badminton enclose the spherical cap, adopts the integrally formed spherical cap in the shape of the horn-shaped curved surface and is provided with 4-8 supporting rods, improves the inlet and outlet of air flow on the premise of ensuring the stable flight, is small in wind resistance and is suitable for outdoor use. The spherical crown and the bracket are integrally formed, so that the manufacturing cost is low, and the consistency and the stability are good.

The invention adopts a three-section structure, and the three parts are assembled in a splicing mode, so that the method is simple, convenient, rapid and efficient.

According to the invention, the spherical crown is independently opened, so that the consistency of the spherical crown is ensured, and the demolding difficulty is reduced. The invention adopts a support form, and ensures the integral strength of the ball. Especially, the reinforcing ribs between the inserting rods and the connecting ribs between the supporting rods ensure that the inserting rods and the supporting rods are more stable and cannot be easily deformed when being impacted, thereby ensuring the flying stability of the ball. The three-section structure of the invention strengthens the waist of the outdoor ball, strengthens the gram weight and the strength and stabilizes the flying of the outdoor ball.
