Abstract
The utility model relates to a sports exerciser, specifically relates to a billiards eyeballing aiming training instrument with a meridian and parallel mould and a tri-dimensional foresight structure. The utility model is characterized in that a substitute object ball is tangent with the outer surface of a meridian and parallel rack which is a frame formed by three circular rings, each two of which are mutually perpendicular. The utility model is advantageous in that the meridian and parallel rack is in a shape of ball, facilitating learners to imagine the cue ball at the bumping moment; the intersection point of three thin rods is a ball core, and is also a target point for learners to aim at; under the situation of not heightening or contracting the rod or not rotating, the pointing direction of a thin rod III is the moving direction of the cue ball after being bumped, thereby learners can develop how to control the moving direction of the cue ball after being bumped through eyeballing training.
Description
Technical field
The utility model relates to a kind of sports movement apparatus, and instrument is aiminged drill in particularly a kind of billiard ball range estimation with graticule moulding and three-dimensional foresight structure.
Background technology
In the billiard movement, if the moment of mother bulb and object ball collision, two ball centre of sphere place straight-line pass target sacks, then object ball necessarily advances bag, and the trend of collision back mother bulb is perpendicular to above-mentioned straight line, if can be before rod, according to the collision of two balls, mother bulb should the loca position, accurately imagines a virtual mother bulb, with mother bulb this virtual mother bulb of directive accurately, object ball must advance bag then.
Summary of the invention
The purpose of this utility model is to provide a kind of billiard ball range estimation with graticule moulding and three-dimensional foresight structure to aiming drill instrument, simulates a virtual mother bulb, practises pointless defective thereby solve the beginner.
To achieve these goals, the utility model by the following technical solutions: it comprises and substitutes object ball, spherical tentering of weft, substitutes that outer surface is tangent between object ball and the spherical tentering of weft is connected, and spherical tentering of weft constitutes framework by three orthogonal in twos annulus.
Three orthogonal in twos annulus have 6 intersection points, and per two intersection points by spherical tentering of weft diameter connect with thin bar I, thin bar II, thin bar III respectively, and thin bar I, thin bar II, thin bar III are vertical mutually in twos.
Thin bar I is perpendicular to desktop, and its length equals circle diameter.One end of thin bar II passes the centre of sphere that substitutes object ball and passes from the other end that substitutes object ball, and the other end of thin bar II passes from spherical tentering of weft.The two ends of thin bar III pass from spherical tentering of weft.Substitute the object ball below and be lined with the ball holder.
The utility model compared with prior art has following advantage:
1, simple structure, effect is obvious, and it is convenient to implement, and does not need to establish in addition the training court, just can practise on common ball table, does not damage and pollutes Billiards table.
2, this device can help the fan to pass through the range estimation training, accurately grasps sack, object ball, mother bulb three space and position relation, can turn out walking of mother bulb and object ball, thereby improve precision.
3, three orthogonal in twos annulus constitute a spherical tentering of weft, sketch the contours of the profile of a ball, are convenient to allow the practitioner mother bulb of impact moment be imagined the joint of three thin bars is exactly the centre of sphere, also are the impact points that the practitioner aims at.
4, contract under the situation of bar or rotation not increasing bar, the thin bar III direction of this device is exactly the direction of motion of collision back mother bulb, can help the fan to pass through the range estimation training, turns out walking of collision stepmother ball held.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing 1: instrument is aiminged drill in a kind of billiard ball range estimation with graticule moulding and three-dimensional foresight structure, it comprises and substitutes object ball, spherical tentering of weft, substitute that outer surface is tangent between object ball 1 and the spherical tentering of weft 2 is connected, spherical tentering of weft 2 constitutes framework by three orthogonal in twos annulus 3, three orthogonal in twos annulus 3 have 6 intersection points 4, per two intersection points 4 by spherical tentering of weft 2 diameters are used thin bar I 5 respectively, thin bar II 6, thin bar III 7 connects, thin bar I 5, thin bar II 6, thin bar III 7 is vertical mutually in twos.
Thin bar I 5 is perpendicular to desktop, and its length equals annulus 3 diameters.One end of thin bar II 6 passes the centre of sphere that substitutes object ball 1 and passes from the other end that substitutes object ball 1, and the other end of thin bar II 6 passes from spherical tentering of weft 2.The two ends of thin bar III 7 pass from spherical tentering of weft 2.Substitute object ball 1 below and be lined with ball holder 8.
