Description

Billiard stick

Technical field

The utility model relates to a kind of billiard stick, and it is suitable to relate in particular to a kind of weight that makes billiard stick and unidimensional traditional solid rod, and makes billiard stick weight moderate, makes the average billiard stick of transmission of strength.

Background technology

Fig. 1 shows first kind of traditional billiard stick 70, and it has a prosthomere 71 and a deutomerite 72, and this prosthomere 71 is provided with a screw 711, and this deutomerite 72 is provided with a spiro tooth part 721, and both can sealed this prosthomere 71 become a stock with this deutomerite 72.Because this prosthomere 71 is natural timber with this deutomerite 72 and makes, there are many wood grain fibers and slit (not shown) in its inside, when bringing into use new billiard stick 70, be constantly with billiard stick 70 bump billiards, make the slit of the many natural timbers in the billiard stick 70 be compressed gradually, after continuing to use a period of time, will make the slit of most natural timber be compressed into a limit, and can't be compressed again.At this moment, use billiard stick 70 to have a kind of sturdy sense, suppose that user's hand applies the strength of 100 units, the transmission of process billiard stick 70 may only be absorbed 1-2 unit, very near desired desirable output strength, so control become very stable in the strength of integral body.Yet, by brand-new billiard stick 70 use always to the time with sturdy sense (being commonly called as " forming the time ") may between a few weeks longer to several month (because of the people, because of timber different).But, if buying new billiard stick 70, the user to just reach state through the so long time with sturdy sense, the time is oversize, significantly reduces user's purchase intention.

In order to shorten the above-mentioned time, there is the dealer to develop second kind of traditional type billiard stick 80, as shown in Figure 2, it comprises: a prosthomere 81 and a deutomerite 82; This prosthomere 81 has a front end 811, a solid part 812 (having one first length L 1), a hollow part 813 (having one second length L 2) and a junction 814; Have a deep hole 815 in this hollow part 813,, form an inner space 84 in it in order to hold the hard force transfer element 83 of a hollow tubular.When the user applies one when exerting oneself F, this F that exerts oneself can be passed to this hard force transfer element 83 (shown in the first component F1 among Fig. 2) and this hollow part 813 (shown in the second component F2 among Fig. 2), passes through this solid part 812 again, at last to this front end 811; Yet it still has following shortcoming:

[1] moves after the center of gravity of billiard stick.Though the transmission that this hard force transfer element makes strength is more direct and more accurate really, but, because this hard force transfer element still has an inner space, cause the weight of this prosthomere to lighten, move after the center of gravity of billiard stick integral body, allow user's batting hold a change, severe patient can produce that rod has some setbacks or strength control problem accurately not.

[2] billiard stick lightens.It in the inner space of this hard force transfer element air, make the gross weight of billiard stick lighten, the user the batting exert oneself the time cause the inertia force of billiard stick also to diminish, the related kinetic energy that moves that influences billiards, severe patient may cause travel path to shorten (to suppose to be moved to second place P2 by the primary importance P1 of Fig. 3, in fact but only advance to the 3rd position P3), or the kinetic energy of rotation reduces and then travel path is departed from and (deviates to dotted line direction V1 as shown in Figure 3, V2), the change that these are slight all may allow the user control ball shakiness and loses in play.

[3] transmission of strength is unequal.Because the existence of inner space makes strength transmission (or reaction force passback) transmit by inner space other hollow part and hard force transfer element, the transmission of strength is unequal.

Therefore, be necessary to research and develop new product, to solve above-mentioned shortcoming and problem.
