Description

With the mother bulb that central point is corrected

Technical field

The utility model relates to a kind of billiard training equipment, is specifically related to a kind of mother bulb corrected with central point.

Background technology

Want to accomplish fluently billiard ball, you must possess two technical ability: (1), accuracy; (2), walk.

Wherein accuracy is basis, and it is advanced for walking.That is, even if your to be next bar ball walked excellent attack point, but your a upper ball is beaten and is lost, and that is not also used.

For accuracy, want to improve it, we can with reference to content below:

Two key elements of high accuracy:

<1>, rod are straight: namely fall from sportsman, front stop aiming at start, experienced by 5 steps: frontly stop aiming->.Stop after fortune bar-> to confirm-> pumping rod-> rod.In this five steps, what you must ensure is, and your club moves all the time on same straight line (this line specialty is called as ball releasing line, as long as namely mother bulb finally runs along this line, just can switch to the correct thickness of object ball and make it enter bag), can not have the skew on any direction, upper and lower, left and right, the point of the final leather point impact of such guarantee on mother bulb is the point wanting in you aim to impact.

<2> aims true, and is divided into 2 points:

A (), object ball aim true: namely in the face of different lower ball angles (this angle is the angle of mother bulb, imaginary ball, sack three formation), you know clearly the position of ball releasing line (i.e. the line of the centre of sphere of the mother bulb centre of sphere and imaginary ball) very much, then fall, club is placed on the extended line of this line, as long as make it the position along this ball releasing line linear running to imaginary ball after final impact mother bulb, just object ball can be cut in bag.And for this ability according to ball angle determination ball releasing line under difference, be then that the continuous accumulation by practising at ordinary times is slowly formed.

B (), mother bulb aim true:

We first explain several definition:

Mother bulb central point: the i.e. centre of sphere position of mother bulb, or with the mother bulb centre of sphere for the centre of sphere, one that makes for radius with leather cue tip radius little spheroid, is below referred to as mother bulb central point;

Extreme position: in order to prevent the phenomenon occurring slide bar (be commonly called as and give a tongue-lashing bar) when impacting, the position of leather point impact mother bulb obviously can not at the spheroid outward flange of mother bulb, it must be the position of outward flange inside at least half leather point again, and any position inside from some position A just can ensure not slide bar when impacting, this position A, is below referred to as extreme position;

Mother bulb center line: comprise mother bulb central point, extend upwardly to the extreme position of mother bulb the top from mother bulb central point along the direction of vertical ground till comprise region, extend downward the extreme position of mother bulb bottom from mother bulb central point along the direction of vertical ground till the region that comprises, be below referred to as mother bulb center line;

Plug or rotation: the position of leather point impact mother bulb is the optional position of non-mother bulb central point;

Pure high bar: impact position is the upper extreme position of mother bulb center line, is below referred to as pure high bar;

Pure low bar: impact position is the lower limit position of mother bulb center line, is below referred to as pure low bar;

King-rod: impact position is mother bulb central point, is below referred to as king-rod;

Middle high bar: along mother bulb center line direction, more than king-rod, below pure high bar, the region comprised, is below referred to as middle high bar;

In low bar: along mother bulb center line direction, below king-rod, more than pure low bar, the region comprised, low bar in being below referred to as;

High bar or top plug: comprise pure high bar, middle high bar, be below referred to as high bar;

Low bar or lower plug: comprise pure low bar, in low bar, be below referred to as low bar;

Zuo Sai: the region that impact position comprises left for mother bulb center line to each limit on the left position, generally includes the left plug of high bar, the left plug of king-rod, the left plug of low bar, is below referred to as left plug;

Right plug: the region that impact position comprises to the right for mother bulb center line to each limit on the right-right-hand limit position, generally includes the right plug of high bar, the right plug of king-rod, the right plug of low bar, is below referred to as right plug;

Jump a queue: for top plug above-mentioned and lower plug, generally we express with high bar and low bar, therefore we are that left plug or right plug are defined as and jump a queue the position of impact mother bulb here, this also meets the custom of most people;

If the impact position of mother bulb is left plug or right plug, the extended line of club when then the travel line of mother bulb can depart from rod, and larger, plug larger (namely impact point more departs from mother bulb center line in other words more close to each extreme position) of having an effect, offset more obvious, and what there will be that mother bulb walks is the phenomenon of camber line, concrete travel line is comparatively complicated, does not repeat them here.

And usually we are subjective do not want to add the impact of left and right plug in, what we aimed at must be just that mother bulb center line impacts.A lot of people scorns to take even a glance to this, think that impact mother bulb center line has been again simple thing only, actually this is not so, I will tell you, and a lot of people is when body of falling aims at, although you do not want to play ball of jumping a queue, but the position that leather point is aimed at not is mother bulb center line, but you but do not find, that is leather cue tip does not aim at the point on mother bulb that your mind will aim at, then is exactly that you think that you do not jump a queue but in fact you have jumped a queue in simple terms.Here we are introduced mainly for situation about taking aim at a little on mother bulb center line, because if this bar ball, you will beat at subjective will jumping a queue, and so no one knows that you want which the point aimed at is on earth at heart.If but your this bar is not jump a queue to beat, the people so standing in your dead astern just can tell you by the point whether aimed on mother bulb center line by the leather cue tip observing you, you take aim at a little have no problem, certainly this also has error, but the yourself comparing action of lying prone sees, he can see more clearly.Teacher Pang Weiguo also said in teaching, normal conditions, if necessity that this bar ball is not jumped a queue, or need not eat storehouse (hitting storehouse) and went to walk, and so in order to ensure goal success rate, did not just jump a queue easily.In fact, under normal circumstances, the ball that we beat, that does not jump a queue is more much more than the situation of jumping a queue.

We are with regard to by king-rod, and as you know, king-rod, lain prone in action aims at sportsman, leather point should be aim at mother bulb central point, and the problem that so I will say has been come.That is exactly that a lot of people can not find mother bulb central point on earth at which, or so says, allow you that a mother bulb is taken and see, you perhaps can find, but allows you action of having lain prone go leather cue tip to aim at mother bulb central point, and you are with regard to genuine misalignment.You also do not believe, I looks down upon you, and you may play ball so for many years, genuine misalignment mother bulb central point.Because of before me contacted much from little just play ball, want to be the little sportsmen of the such great master of Ding Junhui, they are usually in order to this problem is in arguement.And using billiard ball as you of hobby, perhaps they are so diligent so not careful, if but you really have deep love for billiard ball, want it to accomplish fluently, may well ask that you can not find by mother bulb central point, think progressive, may? give an example to you, in the venue that I practises a ball game in the later stage, have two students, they are when practising a ball game one day, because something arguement has been got up.I and coach one ask in the past, just know the problem at arguement mother bulb central point.A say B subjective do not want to jump a queue aim in, be but be with left plug in fact, and B say impossible.At this moment, coach allows B lie prone again, wait him to lie prone after posture, and we stand in his dead astern and to see time, and everybody unanimously thinks that he is natural left plug (namely wouldn't like to jump a queue, always with left plug when can take aim at once falling) really, and himself is not known.B does not still believe, once take a picture to him so we allow him lie prone again, he has write in reply this.Then just see that A is continuously happy.So coach allow A also lie prone, result you how guess, natural right plug.At this moment B is taken turns to proud.I allows coach have a look mine, and he says a little right plug, is not very serious.Then we make trouble and allow coach lie prone.Result at a glance, really very just.Start everybody all sound, but after a while, the people that has surrounded and watched says sentence: " I feels as a little left plug." B says: " I feels very positive! " I starts to feel to seem a little left plug with A, but can not determine, just feel to have differentiated not out because naked eyes look at.Coach bows out, so performed a superpower pure high bar, a superpower pure low bar to us, also has a long table fixed pole.Us are asked after having beaten, you see, and does mother bulb have sidespin? not our not having unanimously.At this moment I stupidly stupidly has asked sentence: " coach, can or can not turn right by your rod, just natural left plug when aiming at is counteracted? " coach is said happy.After this part thing, we because the problem of mother bulb central point still has argued many times.Finally, for those fine distinctions, coach also starts can't say that who is wrong to whom on earth sometimes.

I says this example, is think in fact, and finding mother bulb central point accurately barre head aims at mother bulb central point is in other words not a thing easily.The defect of natural left plug is slowly being changed afterwards as B, also only much better when he takes aim at king-rod, when he take aim at middle high bar, pure high bar, in low bar, pure low bar time, still the defect of natural left plug is had, the point that namely leather point is aimed at still departs from mother bulb center line, always on the left side of mother bulb center line little by little.He says us, has a hunch and oneself takes aim at very positive, not askew.Coach allows his first aim at mother bulb central point at every turn, little by little vertically up moves or moves down again afterwards, until used this method, he is just genuine slowly much better.

Just imagine, you do not want to jump a queue originally, and time trainable, you have but been with natural left and right plug, and so your rod is straight also not all right again, and mother bulb can not be advanced according to the straight route of anticipation, and accuracy can be greatly affected.I constantly thought deeply the reason causing this phenomenon afterwards, found it may is that these two reasons cause:

A the problem of (), dominant eye, this is the problem that veteran Davis said.Somebody is that left eye master looks, and somebody is that right eye master looks, and somebody is then that eyes master looks.For the people that eyes master looks, club just should be placed on below the center of chin, but not eyes master depending on people then should be placed on immediately below dominant eye.For this problem of dominant eye, the people be ignorant of can be using Baidu.com.But have a problem, that be exactly you at every moment can not to determine that club touch the position of chin right on earth.

(b), due to different stances, the inclined degree of health is different, this can cause the distance of your eyes and mother bulb can be different, causes visual error.Also there is a problem, unless you are through permanent vocational training, the posture of oneself is really fixed up, as long as not so you often return and stand different, so often go back to your visual angle all in change.

How in billiard training, to provide simple and reliable supplementary means for mother bulb aims at, become technical problem urgently to be resolved hurrily.
