Hollow plastic ball

This creative hollow plastic ball is mainly applied to the hollow plastic ball technology which can maintain the balance of flight and increase the structural strength.

According to the present, there is a ball-and-shoulder movement of parent-child music, which is a sports toy made of hard plastic plastic. The sports toy includes a hollow plastic ball (commonly known as a hole ball) having a plurality of holes on its surface.

The above-mentioned hole ball is manufactured by providing a ring of combined ribs on the inner circumference of two symmetrical semi-spherical shells, and melting the joint portion when combined, and then joining the two semi-spherical shells into one body, the melting part Together, after cooling and setting, the combination of the two semi-spherical shells is firmly bonded.

However, after the above-mentioned hole ball is completed, a ring of ribs will be left on the inner circumference of the hole ball. Since the hole ball will rotate during the flight, the ring will affect the hole ball. The weight is out of balance, which in turn causes the hole ball to float freely due to the shift of the center of gravity. It cannot ensure a stable parabolic trajectory when the hole ball is flying, and increases the difficulty in throwing the hole ball. At the same time, the inside of the hole ball Since only this circle is combined with the ribs, the structural strength of the hole ball is not uniform, and it is easy to be deformed by impact or trampling, which is a problem and a deficiency that have yet to be solved.

The creator is currently engaged in the manufacture and design of related products, accumulated many years of practical experience and experience, and has actively invested in the spirit of innovation and improvement in response to the existing problems and shortcomings of traditionally used holes, and completed the hollow plastic ball.

The new technical solution to solve the problem and the effect against the prior art is that the hollow plastic ball is integrally joined by two semi-spherical shells having a plurality of holes on the surface of the semi-spherical shell. The inner circumferential surface of the casing is provided with vertical ribs arranged vertically in a half circle. When combined, the two semi-spherical spherical shells are integrated into one body, and when the inner circumferential surface of the hollow plastic ball is combined, it is formed by excess plastic. The horizontal ribs and the vertical ribs arranged in a cross-arc shape, in addition to maintaining the balance of weight during flight, avoiding the emptying of the plastic ball due to the shift of the center of gravity, ensuring a stable parabolic trajectory throw when the hollow plastic ball is flying. In addition to the easy connection, at the same time, when the inner circumferential surface of the hollow plastic ball is combined, the 360° surrounding horizontal rib formed by the excess plastic and the vertical rib arranged in a cross-arc shape increase the structural strength of the hollow plastic ball. It can avoid the deformation of the hollow plastic ball due to impact or trampling, and has an improvement in efficiency, reaching its main purpose.

In order to make it easier for those who are familiar with this skill to understand the construction content of the creation and the functional benefits that can be achieved, a specific embodiment will be listed, and the detailed description will be given as follows: a hollow plastic ball, respect Please refer to the first and second figures: a partial cross-section and a three-dimensional exploded view of the three-dimensional combination of the creation. As shown in the third figure, it is a three-dimensional schematic diagram of the semi-spherical shell of the present invention. And the fourth and fifth figures are shown: the cross-section combination of the creation and the D-D cross-section of the fourth figure. The hollow plastic ball is mainly composed of two mutually symmetric semi-spherical spherical shells 10, wherein: the surface of the semi-spherical spherical shell 10 has a plurality of holes 11 at the inner circumferential surface of the semi-spherical spherical shell 10 There are vertical ribs 13 arranged perpendicularly to the horizontal ribs 12 formed by the combination of the horizontal ribs 12, the horizontal ribs 12 are 360°, and the vertical slats 13 are 180°; when combined, the two semi-spherical shells are first combined The horizontal rib 12 portion of the 10 is welded, and then the two semi-spherical shells 10 are vertically pressed and pressed by a press mold, so that the molten horizontal ribs 12 are heated and joined together, and the two semi-spherical balls are cooled and shaped. The casing 10 is formed into a hollow plastic ball, and when the inner circumferential surface of the hollow plastic ball is combined, the 360° surrounding horizontal rib 12 formed by excess plastic and a cross-arc arrangement and vertical rib 13 are formed.

In the above-mentioned hollow plastic ball, the two semi-spherical spherical shells 10 can be integrally formed by means of ultrasonic welding or by means of an ultrasonic bonding method.

By combining the above-mentioned various component structures, the present invention provides a kind of Hollow plastic ball, in practical application: When the hollow plastic ball is thrown, due to the inner circumferential surface of the hollow plastic ball, the 360° surrounding horizontal rib 12 and the cross-arc configuration are formed by the excess plastic. The vertical ribs 13, so that the hollow plastic ball can maintain the balance of weight during flight, can avoid the hollow plastic ball floating freely because of the shift of the center of gravity, ensuring a stable parabolic trajectory when the plastic ball is flying. At the same time, when the inner circumferential surface of the hollow plastic ball is combined, the 360° surrounding horizontal rib 12 formed by the excess plastic and the vertical rib 13 arranged in a cross-arc shape can increase the structural strength of the hollow plastic ball. It can avoid the deformation of the hollow plastic ball due to impact or stepping.

Based on the above findings, the creative department is providing a hollow plastic ball. After the actual production of the creator and the repeated operation test, it is confirmed that the functional benefits expected by the creation can be achieved, and at the same time, it is still unknown. First of all, it has the value of industrial use. It is true that it has met the requirements of the practicability and progress of the new patent, and has applied for a new type of patent to the bureau in accordance with the provisions of the Patent Law.
