Description

A kind of reaction sphere

Technical field

The utility model relates to a kind of physical training apparatus fields, more specifically, it is related to a kind of reaction sphere.

Background technique

Reaction sphere is made into rubber, so the fairly good of elastic force makes it dish out since the surface of reaction sphere is provided with cambered surface Or falls to generate at hard ground and be difficult to expect rebound direction, and need to collect and neutralize fast reaction and can just catch up with and grab To ball, relatively be suitble to athletes training response ability, eye hand coordination ability, can allow in this way you obtain one it is more interesting and Dynamic exercise.The speed that resilience performance determines landing rebound is freely landed, it is better freely land resilience performance, lands and rebounds Speed it is faster.Therefore the key index sprung back as evaluation response ball superiority and inferiority is freely landed.Reaction sphere is experienced in the world The essential product of reaction speed is practised, tennis, shuttlecock, the sportsmen such as table tennis are suitable for.

A kind of reaction sphere is fixedly arranged on multiple raised the 2 of 1 surface of sphere referring to Fig. 1, including sphere 1, adjacent protrusion 2 it Between form the groove 3 of multiple quadrangles or triangle, the surface of protrusion 1 offers cambered surface 21, sphere 1 is thrown away on the ground, groove 3 Contact area between the cambered surface 21 being capable of increasing in groove 3 surrounding protrusion and ground, so that the height for making sphere 1 rebound is higher And rebound direction more to.

But for the sportsman for having wound to body, when using reaction sphere, to the multidirectional of the reflection direction of reaction sphere Property require it is less high, so that reaction sphere be made not to be suitable for the sportsman that body has wound.

Utility model content

In view of the deficienciess of the prior art, being set in groove the purpose of this utility model is to provide a kind of reaction sphere It is equipped with grafting block, reduces the cambered surface of protrusion and the contact area on ground, reduces reaction sphere and ground face contact back reflection direction Diversity.

To achieve the above object, the utility model provides following technical solution:

A kind of reaction sphere, including sphere are installed with protrusion on sphere, multiple quadrangles or three are constituted between adjacent protrusion Angular groove is removably connected with grafting block corresponding with groove shapes in the groove.

By using above scheme, grafting block is plugged in groove, it can be according to different people to reaction sphere reflection direction Grafting block is installed in the requirement of polytropism, selection in groove, and grafting block reduces the cambered surface of protrusion and the contact area on ground, from And reduce the polytropism of reaction sphere and ground face contact back reflection direction, so that reaction sphere be made to be adaptable to the telemechanical of body in spite of wound Member.

Preferably, being connected with connecting column in the groove, the bottom of grafting block offers the connecting hole for connecting column grafting, Connecting column is installed with grafting ring close to the end of grafting block, and the accommodating chamber of clamping grafting ring is offered in grafting block.

By using above scheme, when grafting block is sheathed on connecting column, make grafting ring on connecting column from connecting hole In pass through, be finally connected in accommodating chamber, grafting block can be plugged in groove.

Preferably, the grafting ring circumferentially offers the second inclined-plane close to the end of grafting block.

By using above scheme, the second inclined-plane can facilitate the grafting ring on connecting column to be plugged in connecting hole.

Preferably, the connecting column is to be detachably connected with groove.

It by using above scheme, is detachably connected between connecting column and groove, facilitates and remove connecting column from groove, Connecting column is replaced.

Preferably, offering the circular hole for connecting column grafting in the groove, connecting column is installed with close to one end of circular hole Stop collar, one end in groove far from circular hole offer the cavity of clamping stop collar.

By using above scheme, connecting column is plugged in circular hole, passes through the stop collar on connecting column from circular hole, It is finally connected in cavity, connecting column can be plugged on groove.

Preferably, the one end of the stop collar far from grafting ring circumferentially offers the first inclined-plane.

By using above scheme, the first inclined-plane can facilitate the stop collar on connecting column to be plugged in circular hole.

Preferably, offering the second fillet at the top edge of the grafting block.

By using above scheme, when sphere is flung at ground, the second fillet can be reduced between grafting block and ground Abrasion.

Preferably, offering the first fillet at the seamed edge of the convex top.

By using above scheme, when sphere is flung at ground, the first fillet can reduce the mill between protrusion and ground Damage.

In conclusion the utility model has the advantages that compared with the prior art

1. being equipped with grafting block in groove, grafting block can reduce the contact area between cambered surface and ground in protrusion, To reduce the polytropism of reaction sphere and ground face contact back reflection direction, so that reaction sphere be made to be adaptable to body in spite of wound remote It mobilizes；

2. being removably connected with connecting column in groove, grafting between connecting column and groove, grafting block interleaves with connecting column It connects, facilitates the installation and removal of grafting block, also facilitate the installation and removal of connecting column.
