Abstract

The utility model provides a low-speed golf exercising ball, which relates to the golf sport field. By arranging a radial annular speed reducing device which takes the axis as the symmetrical shaft of the weight and the distance on the ball body, the fly speed of the low-speed golf exercising ball of the utility model can be greatly reduced, and then exercising powerful hitting golf in room and other narrow spaces become possible, and the popularization and development of the golf sport are facilitated.

Description

Low speed Golfing practice ball

Technical field:

The utility model relates to the golf sports field, the particularly a kind of low speed Golfing practice ball that can practise hard hit in indoor actual combat.

Background technology:

Regular golf generally is made by the synthetic rubber and the outer field band pit rigid plastics of coating of inside, about quality 45 grams, the general 42.6-42.8 millimeter of diameter, has good resiliency characteristics, can fly to nearly 300 meters distance when impacting energetically, this specific character has determined to use regular golf can't practise hard hit under battle conditions at small spaces such as rooms at all.In order to address this problem, hollow light plastic golf and light weight and soft PU foaming golf become a kind of selection of exercise in the inlet chamber, though both can not fly farly after impacting energetically as regular golf, but because the spheroid lower resistance characteristic of above-mentioned golf, make that the ball speed after impacting is still very fast, bounce is bigger after running into barrier, the higher risk of hurting sb.'s feelings is still arranged, therefore these two kinds of golf are general only uses as the exercise chipping, and because the rolling characteristic of spheroid, can fly to such an extent that be everywhere after the bounce-back, in the such complex environment in room, be difficult to seek.In sum, be to be implemented in the small space such as room the hope that exercise under battle conditions impacts golf energetically by the single method that alleviates the golf quality.

Summary of the invention:

The purpose of this utility model provides a kind of low speed Golfing practice ball, overcome that regular golf elastic force is big, quality is big, the spheroid form resistance is little, can't practise impacting energetically the disadvantage of golf at small spaces such as rooms under battle conditions, thereby make and in little space such as room, just can enjoy the enjoyment that exercise under battle conditions impacts golf energetically, have security preferably simultaneously again.

For achieving the above object, the technical scheme that the utility model adopted is: a kind of low speed Golfing practice ball, and it comprises spheroid and deceleration device; Spheroid is constituted by more than one low density materials; Deceleration device is the radiation endless belt, and this endless belt becomes less than 90 ° angle with central shaft and with respect to central shaft quality and distance symmetry, its small-caliber end diameter is less than sphere diameter; The small-caliber end of deceleration device embeds spheroid.

Spheroid comprises PU skin, cork, foaming PU, and foaming PU is an internal layer, and cork is the intermediate layer, and the PU outer cortex is glued between three layers, and three layers of sphere diameter of being formed are smaller or equal to regular golf diameter.

The outer surface of cork has the distinctive pit of regular golf, and the PU suitcase is wrapped up in the outer surface that is glued at cork and had and the same pit in cork surface.

Spheroid is in the part that deceleration device surrounds, and can be arcwall face or is the plane.

Deceleration device can be made of skeleton and covering of the fan; On some skeletons of covering of the fan attached to arrangement at certain intervals, and connect and compose the radiation endless belt; The deceleration device of skeleton and covering of the fan formation becomes the angle less than 90 ° with its central shaft, and becomes quality and distance symmetry with its central shaft.

Deceleration device can be the uniform radiation endless belt of integral thickness.

Deceleration device can be made of the skeleton and the covering of the fan of heavy caliber end certain-length; Skeleton and covering of the fan are to the angle of central axis direction fillet bending greater than 90 °, and skeleton after the bending and covering of the fan and its central shaft quality and distance are symmetrical.

Deceleration device can comprise that feather, jag and sphere protect head; Jag is fixed on the position of pen feather, and its feather overlaps arrangement successively; The quantity of jag is more than or equal to 1; Tip, feather upper end gummed has sphere to protect head.

The small-caliber end of the deceleration device that is made of skeleton and covering of the fan is embedded in the embedded hole of spheroid, embedded hole with the quantity of skeleton, at interval, angle and the degree of depth be consistent.

The small-caliber end of the uniform radiation endless belt of integral thickness formula deceleration device embeds in the annular recess of spheroid.

The small-caliber end of deceleration device and spheroid can be shaped to one.

The low speed Golfing practice ball that the utility model provides is compared with existing golf, has following beneficial effect:

The utility model provides people in the indoor new way that waits small space to practise impacting energetically golf under battle conditions, and its sphere structure is compared with light and soft foaming PU Golfing practice ball with the hollow plastics Golfing practice ball of existing lighter weight has following advantage:

1, the spheroid resistance is big, speed is low, is suitable for indoor actual combat exercise hard hit.This is owing to additionally increased the deceleration device of a radiation endless belt formula on the spheroid, has changed sphere structure; Particularly conventionally deceleration device becomes 40 ° angle with central shaft, and the diameter of its heavy caliber end is greater than sphere diameter, and the flight resistance of spheroid is greatly improved, and can realize that therefore people practise the hope of hard hit under battle conditions on indoor security ground.

2, impact back flight circuit and stablize, guaranteed that the practitioner can judge the correctness of posture according to the spheroid drop point after impacting.Because therefore the deceleration device that increases has kept the stable aerodynamic feature of golf ball flight with its central shaft quality and distance symmetry.

3, spheroid bounce-back number of times reduces, and it is easy to pick up ball.Conventional spheroid can repeatedly rebound and rotating direction without limits, the difficulty of picking up ball is also very big; And the deceleration device that increases has destroyed the rolling characteristic of conventional spheroid, and is very fast static after spheroid is run into obstacle or bounce-back and landed, and makes to pick up ball and become easy.

4, light weight and sound are melodious.The combination of multiple materials such as foaming PU, cork and PU skin reduces spheroid weight, elastic force size and sound property can take into account consideration, and when spheroid contacted fast with the sweet spot of club, sound was very clear and melodious, had improved the interest of exercise to a certain extent.
