Abstract

The utility model relates to billiard goal assisting devices, in particular to a top-shaped laser collimator for billiard goal. The top-shaped laser collimator comprises a positioning device and a displaying device, wherein the positioning device comprises a shell, a 'minus'-shaped laser transmitter, of which the head extends out of the top end of the shell, is placed in the shell, a turning rod, of which the tail end extends out of the tail end of the shell, is fixedly arranged at the tail of the 'minus'-shaped laser transmitter, and a turning knob is further arranged at the tail end of the turning rod; the displaying device comprises a base, an upright first telescopic rod is fixedly arranged on the base, a horizontal second telescopic rod is fixedly arranged at the top of the first telescopic rod, a circular laser transmitter, of which the head faces downwards, is fixedly arranged at the end part of the second telescopic rod, a supporting plate, of which a plate face is provided with an opening, is fixedly arranged in the shell of the positioning device, and a rod body of the turning rod penetrates through the opening of the supporting plate. The top-shaped laser collimator for the billiard goal, provided by the utility model, has the advantages that people can be helped to quickly and accurately find the aiming point of a target ball, the goal rate of the target ball is increased, and the problem that the positioning of the aiming point is inaccurate when the target ball is hit by people is solved.

Description

Billiard goal top shape laser aiming instrument

Technical field

The utility model relates to the servicing unit of billiard goal, is specially billiard goal top shape laser aiming instrument.

Background technology

How billiard movement, from its origin, makes the object ball being impacted accurately enter bag, becomes a difficult point of this motion, certainly also becomes the place that can produce so large interest of this motion.The aiming point that most of billiards lovers enters bag to object ball can not accurately be located, cause square stance to have deviation, object ball enters bag often by fortune, although and the numerous elite of billiard ball circle are continuous, the carrying out of always enjoying it a large amount of research, work out in theory radius and aimed at method, this method can help people to find aiming point, but this method all rests on some in theory, in calculating and in hypothesis, practical application is not strong, also be difficult to accurately navigate to aiming point, so up to the present, most of billiardist exists blindly and batters, take a chance and impact into bag, become the biggest obstacle that this motion is carried out, simultaneously, when even billiard ball specialty player plays billiard ball and training usually, utilize this method of sight also more difficult, make sports level be difficult to quick raising.

Summary of the invention

The utility model is located inaccurate problem in order to solve people's aiming point when impacting object ball, and billiard goal top shape laser aiming instrument is provided.

The utility model is to adopt following technical scheme to realize: billiard goal top shape laser aiming instrument, comprise positioner and display unit, positioner comprises housing, in housing, be placed with the in-line generating laser that head stretches out housing front end, the afterbody of in-line generating laser is fixed with the dwang that tail end stretches out housing tail end, is also provided with knob on the tail end of dwang; Display unit comprises base, is fixed with the first vertical expansion link on base, and the second expansion link of the level that is fixed with is rotated at the top of the first expansion link, and the end of the second expansion link is fixed with head circular generating laser down.

During use, the length of the first vertical expansion link in adjustment display unit and the second expansion link of level, and rotate the position of the second expansion link, make the head of circular generating laser launch the centre point position of circular laser circle over against the top of object ball, making the diameter that is presented on the circular laser circle on billiards table face that circular generating laser sends is 114mm or 104mm(Chinese style eight balls, the diameter of English nine balls and Kai Lun ball is 57mm, Snooker is 52mm with the diameter of ball), then the in-line laser rays line sending with the in-line generating laser on knob rotary positioning apparatus, the Goal line of in-line laser rays and object ball is overlapped, the intersection point that is presented on the circular laser circle on billiards table face that in-line laser and circular generating laser send is the aiming point of object ball, like this, utilize this laser aiming instrument to navigate to easily and effectively the aiming point of object ball, object ball can accurately be impacted into bag.

Radius aiming method is on the extended line of the Goal line of object ball, to find the method for the point that the distance with object ball is radius, the distance of this distance objective ball is that the point of radius is aiming point, the diameter that is presented on the circular laser circle on billiards table face that circular generating laser sends is 114mm or 104mm, the radius that the beeline of the projection on record of the point on this circle laser circle and object ball is object ball, therefore, first in-line laser rays is adjusted to the Goal line of object ball and overlapped, the intersection point that is presented on the circular laser circle on billiards table face that in-line laser rays now and circular generating laser send is the aiming point of object ball, circular generating laser is existing structure, the diameter of circular laser circle that it sends and the head of circular generating laser are launched the distance dependent of the centre point position of circular laser circle and the plane at circular laser circle place, therefore as long as adjust the length of the first expansion link, just can on billiards table face, present the circular laser circle that diameter is 114mm or 104mm.

Above-mentioned billiard goal top shape laser aiming instrument, is fixed with the gripper shoe of perforate on plate face in the housing of positioner, the body of rod of dwang is through the perforate in gripper shoe, and gripper shoe has supporting role to dwang, has increased the stability of positioner.

Above-mentioned billiard goal top shape laser aiming instrument, the top of the first expansion link is fixed with bearing, is inserted with vertical dwang in bearing, and the second expansion link is fixed on dwang, realize so easily the rotation of the second expansion link, facilitated the object ball on circular generating laser aligning case face.

Above-mentioned billiard goal top shape laser aiming instrument, the housing of described positioner is fixed on A-frame, has facilitated putting of positioner.

The billiard goal top shape pointing instrumentation that the utility model provides can help people to find the aiming point of object ball fast and accurately, has improved the rate of goals of object ball, has solved people's aiming point when impacting object ball and has located inaccurate problem.
