Stretch Stress Relief Ball

The present invention provides the technical field of a sports pressure relief device, and in particular, provides a kind of stretch pressure relief ball. The wear-resistant spherical ring and the arc-shaped wear-resistant ring are separated to make the rotation movement smoother. The intermediate connector is The edge of the inner hole is set in an arc to avoid scratches when the elastic cord is stretched. Accordingly, a rope-pulling sports equipment can be formed so that the holding part forms a grip, and the elastic cord acts as a source of resistance for the interactive action of tensioning and relaxing. , effectively achieves various stretching and pressure-relieving movements and increases the service life of elastic ropes.

Click, refer to Figure 9. The inventor applied for a new patent for an early creation of a dynamic stretch pressure relief ball, which was approved by type review No. 101218168. The sales and use of the product have indeed achieved the expected results. However, its common knowledge The shapes of the hollow semi-circular spherical parts 91a and 91b are not the same, so if two sets of molds are needed, the cost will be doubled, which is quite uneconomical. However, the conventional hollow semi-circular spherical parts 91a and 91b only differ in the head end. For small parts, if only the differences are isolated and molded, not only the mold will be small, but also if there are changes, it will be easy to modify, and the cost will be relatively much less. On the other hand, the conventional hollow hemispherical parts 91a, 91b are different from the conventional hollow hemispherical parts 91a and 91b. The hollow semicircular spheres 92a and 92b form a circle The ball, and the conventional rings 93a, 93b and the conventional hollow concave spheres 94a, 94b form a holding part. The ball and the holding part are the places with the largest amount of activity during exercise or pressure relief, and are also places where high friction occurs. When used for a long time, it is easy to wear and cause damage, and the ball and the holding part are generally made of the same material, so it is easier to get stuck when turning, and the rotation is not smooth, and it is also easy to cause movement. The mood cannot be relieved, or the side effect of causing a heavy mood needs improvement. However, when the conventional elastic rope 95 passes through the tubular joint 911 of the conventional hollow semi-spherical spherical member 91a, it will contact the inner hole edge at right angles to the inner hole. 912 is scratched, which can easily cause scratches on the conventional elastic cord 95. When the scratches reach a certain level, there is a possibility of breakage, so there is a need for improvement.

Therefore, in view of the problems existing in the above-mentioned conventional structures, how to develop an innovative structure that is more ideal and practical to meet the ardent expectations of consumers is also the goal and direction that relevant industries must work hard to develop breakthroughs.

In view of this, the inventor has many years of experience in the manufacturing, development and design of related products. After detailed design and careful evaluation based on the above goals, he finally arrived at a truly practical invention.

The main purpose of the present invention is to provide a stretch pressure relief ball. The wear-resistant spherical ring and the arc-shaped wear-resistant ring are separated to make the rotation movement smoother. The inner hole edge of the intermediate connecting member is set in an arc to avoid The elastic rope is scratched when it is stretched. Accordingly, to form a rope-pull sports equipment, the holding part forms a grip, and the elastic rope acts as a source of resistance for the interactive action of stretching and relaxing, effectively achieving Various stretching and pressure-relieving exercises and extending the service life of elastic ropes.

In order to achieve the above object, the present invention provides a stretch pressure relief ball, which includes: two hollow semicircular spherical parts are protrudingly provided with a tubular joint part, and an elastic rope first penetrates an intermediate connecting part, two rings, and two arc-shaped wear-resistant rings. and two hollow semi-circular spheres, fix one of the first and second ends of the elastic cord with the two elastic rope fixing pieces respectively. The two hollow semi-circular spheres and the two hollow semi-circular spheres form two spheres. Each hollow concave sphere is obtained. First, a wear-resistant spherical ring is assembled, and the free ends of the two rings are combined with a hollow concave sphere, so that the two hollow concave spheres and the rings form two holding parts, and the holding part can only be moved along the direction of the round balls. The ball cannot come out of the ball due to directional movement. The ball and the holding part are completely separated by a wear-resistant spherical ring and an arc-shaped wear-resistant ring. The wear-resistant spherical ring and arc-shaped wear-resistant ring can resist wear and assist in sliding. To make the rotation smoother, the independent production of the middle connecting piece greatly reduces the mold and the cost, and makes modifications easier. One end of the middle connecting piece is glued and fixed, and the edge of the inner hole at the other end is arcuate to prevent scratches when the elastic rope is stretched. This makes the elastic rope more durable and has a longer life. The design of the intermediate connector also allows the two sets of balls to be molded in the same set, which saves costs. The whole piece forms a rope-pull sports equipment, so that the holding part can be formed The grip, while the elastic rope acts as a source of resistance to perform interactive actions of tensioning and relaxing, effectively achieving various stretching and pressure-relieving movements and increasing the service life of the elastic rope.

Regarding the technology, means and effects used in the present invention, a preferred embodiment is given and described in detail below with reference to the drawings.
