Abstract
The utility model provides a kind of billiard ball and aimings drill articles for use, trainer is helped to grasp the straight line of two described in background technology, in order to realize above-mentioned technical purpose, the utility model provides following technical scheme, it comprises object ball main body, and with the ruler that object ball main body is fixedly connected with, the width of described ruler equals the radius of object ball main body, ruler ascender line through the centre of sphere of object ball, ruler lower along the line with object ball plane tangent.
Description
Technical field
The invention belongs to a kind of billiard training articles for use, belong to a kind of billiard ball especially and aiming drill articles for use.
Background technology
When billiard training, coach, in order to improve the accuracy of player, requires that player grasps two straight lines usually, and Article 1 is through the straight line that the object ball centre of sphere points to sack, another is through the contact point of object ball with table top, point to the straight line of sack, in order to more visual in image, coach can guide student with a vivid metaphor, require that student imagines a rimmer knife exactly, pierce through the Lower Half of ball, and point to sack, also there is no corresponding teaching and training apparatus at present.
Summary of the invention
The invention provides a kind of billiard ball and aiming drill articles for use, trainer is helped to grasp the straight line of two described in background technology, in order to realize above-mentioned technical purpose, the invention provides following technical scheme, it comprises object ball main body, and with the ruler that object ball main body is fixedly connected with, the width of described ruler equals the radius of object ball main body, ruler ascender line through the centre of sphere of object ball, ruler lower along the line with object ball plane tangent.
Accompanying drawing explanation
Fig. 1 is organigram of the present invention,
Fig. 2 is the schematic diagram of the embodiment of the present invention one,
Fig. 3 is the organigram of the embodiment of the present invention two,
Beneficial effect of the present invention
The present invention can help trainer to grasp the important straight line of in billiard training two, and Article 1 is through the straight line that the object ball centre of sphere points to sack, and another is through the contact point of object ball with table top, points to the straight line of sack,
Detailed description of the invention
Embodiment one
By reference to the accompanying drawings 2, in this embodiment, a triangular is fixedly connected with in the other side of ruler 2, the thickness of thin slice is ignored, vertex of a triangle corresponding to thin slice is respectively A, B, C, angle A is 45 °, and on the extended line on base AC edge under ruler (2), summit B is on the extended line on the upper edge of ruler (2).
C point is also the contact point of same Billiards table.
When training, this device can help trainer to grasp the geometry rule of ABP sight alignment, and skilled finds an A that scores.
Embodiment two
3 in the other side of ruler (2) by reference to the accompanying drawings, be fixedly connected with a rectangular sheet, the thickness of thin slice is ignored, corresponding rectangle is EOGH, on the extended line on rectangle base HG edge under ruler (2), on the extended line on top EO edge on ruler, O is the position of the centre of sphere, G is the contact point of table top, and the exposed radius asking the part EF length of outside to equal ball in rectangle top, rectangular height equals the radius of billiard ball.
When training, this device can help trainer to grasp to score point to equal the geometry rule of the radius of ball from the distance of sphere, and E, H are goal points.
