Abstract
The invention relates to a sports appliance, in particular to a billiard visual aiming training instrument with a meridian and parallel shape and a three-dimensional sight bead structure. External surfaces of a substitute target ball and a spherical meridian and parallel bracket are tangent to each other, and the spherical meridian and parallel bracket forms a framework by three pairwise vertical circular rings. The three pairwise vertical circular rings form the spherical meridian and parallel bracket to sketch out a spherical contour, which facilitates a practitioner to image cue balls in instant collision; and the intersection point of three slender rods is a spherical centre as well as a target aiming point of the practitioner. Under the condition of not adding topspin and backspin or sidespin, the pointed direction of the slender rod III of the training instrument is the motion direction of the collided cue balls, which can help an enthusiast master the moving orientation of the collided cue balls through visual training.
Description
Technical field
The present invention relates to a kind of sports movement apparatus, appearance 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 ofs sphere place straight-line pass target sack; 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 object of the present invention is to provide a kind of billiard ball range estimation to aiming drill appearance, simulate a virtual mother bulb, practise pointless defective thereby solve the beginner with graticule moulding and three-dimensional foresight structure.
To achieve these goals, the present invention adopts following technical scheme: 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 through 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 each other 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 present invention 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, on common ball table, just can practise, and 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 let the practitioner mother bulb of impact moment 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 invention.
The specific embodiment
1 couple of the present invention makes further detailed description below in conjunction with accompanying drawing: appearance 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, and per two intersection points 4 through spherical tentering of weft 2 diameters connect with thin bar I 5, thin bar II 6, thin bar III 7 respectively, and thin bar I 5, thin bar II 6, thin bar III 7 are vertical each other 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.
