Abstract
The utility model provides a kind of billiard training articles for use, trainer can be helped to grasp introduce in background technology three straight lines, in order to realize appealing technical purpose, the utility model takes following technical scheme: it comprises the billiard ball main body with fixed underpan, the straight thin bar in upper strata connected with billiard ball top, the straight thin bar in middle level through the billiard ball centre of sphere and the straight thin bar of lower floor through fixed underpan center, the straight thin bar in described upper strata, the straight thin bar in middle level, the straight thin bar of lower floor are parallel to each other in same plane, keep vertical relation with same axis.
Description
Technical field
The present invention relates to a kind of billiard training articles for use, particularly relate to a kind of billiard training articles for use.
Background technology
In network virtual billiard movement, the visual angle of player is vertically bowing and see from top to bottom, what see is also a plane picture, and in entity billiard movement, sporter it is seen that a 3 D stereo picture, score point determination, to usually can not determine simply by some plane geometry, but will by the geometric element of some solids, such as following three straight lines: straight line one, is parallel to the straight line of desktop through object ball summit; Straight line two, is parallel to the straight line of desktop through the object ball centre of sphere; Straight line three, through the contact point of object ball with desktop, is close to the straight line of desktop.
Above-mentioned three straight lines are parallel to each other, and same perpendicular in the plane of desktop, do not have a training articles for use to help practitioner to grasp above-mentioned three straight lines at present.
Summary of the invention
The invention provides a kind of billiard training articles for use, trainer can be helped to grasp introduce in background technology three straight lines.
In order to realize appealing technical purpose, the present invention takes following technical scheme:
It comprises the billiard ball main body with fixed underpan, the straight thin bar in upper strata connected with billiard ball top, the straight thin bar in middle level through the billiard ball centre of sphere and the straight thin bar of lower floor through fixed underpan center, the straight thin bar in described upper strata, the straight thin bar in middle level, the straight thin bar of lower floor are parallel to each other, and in same plane, keep vertical relation with same axis.
Beneficial effect of the present invention
The present invention contributes to the stereo space sense cultivating trainer, trainer is allowed to hold some important geometric elements of object ball, thus hold goal point accurately, specifically, trainer by this device can grasp accurately perpendicular to desktop, billiard ball are cut in half risers, in this risers the summit of billiard ball, two balls are correct in this risers the point of impingement, trainer imagines that in this risers straight line is from summit, through the point of impingement, extend to desktop and just can draw goal point.
Accompanying drawing explanation
Fig. 1 is organigram of the present invention.
Fig. 2 is the schematic diagram of the embodiment of the present invention 1.
Fig. 3 is the schematic diagram of the embodiment of the present invention 2.
Embodiment of the present invention
Embodiment 1: by reference to the accompanying drawings 2, the present embodiment at the middle and upper levels straight thin bar (2) with the summit P of ball for boundary spot printing dyes two kinds of different colors, so that trainer is identified by a point bound pair separation P for color, during training, this device is placed on the position that billiard table is specified, trainer can observe summit P intuitively, and the straight thin bar in middle level (2) is with the joining Q on billiard ball surface, and imagine the extended line of P, Q line, extend to the straight thin bar of lower floor (3), its joining R scores a little exactly.
Embodiment 2: by reference to the accompanying drawings 3, in the present embodiment, the straight thin bar in upper strata (2), the straight thin bar in middle level (3), between the straight thin bar of lower floor (4), be connected with longitudinal straight thin bar m by longitudinal straight thin bar l, longitudinally straight thin bar l and longitudinal straight thin bar m is all parallel to each other with the longitudinal axis n of billiard ball, longitudinally straight thin bar m is close to billiard ball surface, longitudinally the spacing of straight thin bar l and longitudinal straight thin bar m is the radius of billiard ball, during training, practitioner is familiar with upper strata straight line pole (2), middle level straight line pole (3), lower floor's straight line pole (4), longitudinal axis n, the longitudinally spatial relationship of straight thin bar m and longitudinal axis n totally six straight lines, wherein all on longitudinal axis l points are all goal points.
Claims (1)
