Description

Chinese style is pitched---the billiard ball hack lever of collapsible multistage adjustable double lower support leg height

Technical field:

The utility model belongs to billiard ball hack lever manufacturing technology field, is specifically related to a kind of Chinese style fork---the billiard ball hack lever of collapsible multistage adjustable double lower support leg height.

Background technology:

Known to me, billiard ball are one of sports of extensively existing of the whole world, the Western countries America and Europe is prevailing, the numerous teenagers of present China and have deep love for billiard ball personage get more and more, be that the sportsman of representative is in the world to occupy prostatitis by it with Ding Junhui, driven the more masses of China to participate in, there are billiards lovers and billiard table in even each rural area, does not more say in city.The game rule of billiard ball is that sportsman impacts Archon with various support for fulcrum club, hits colour ball, and making colour ball enter Bian Ge hole, storehouse is score.First, whose colour ball of throwing into of second sportsman is many, long-pending mark many who be victor, usual sportsman take finger as fulcrum, Archon is impacted with club, but numerous colour ball is Protean position on ball table, often have the position that colour ball blocks fortune bar, want fortune bar position best just needs to be used as fulcrum by specific purpose tool, conventional hack lever is divided into three kinds, low hack lever, middle hack lever, high hack lever, and their pattern is just many, as fancy fork, English fork, American fork, spider, deer horn is pitched, trunk is pitched, butterfly is pitched, bat fork etc., no matter which kind of fork is namely fixing low, in, the height of high three sizes, people want more precisely a bit, want still do not have at present with the hack lever of the 4th kind of height, arbitrfary point such as from low bar to high bar cannot realize, also cannot realize higher than high bar, the undesirable part of Here it is these three kinds of hack levers current, provides the hack lever of handy collapsible multistage adjustable double lower support leg height with regard to the hack lever needing us to create exploitation multiple spot height more accurately for sportsman.

Summary of the invention:

The utility model is exactly the deficiency in order to solve the above, a kind of Chinese style fork---the billiard ball hack lever of collapsible multistage adjustable double lower support leg height provided, and it comprises: pitch on 1, 2 crossbeams, 3 fixation forks, 4 movable forks, 5 handles, 6 collision beads, 7 springs, 8 shallow round pools, 9 back cover dells, 10 spring shims, 11 sunk head rivet holes, 12 sunk head rivets, 13 twist handle screw hole, 14 via holes putting on fork, 15 via holes fastening fixed fork, 16 pin hole compositions, it is characterized in that: the upper end of upper fork 1 is the half of spider, middle part is disc, there is multiple shallow circular hole 8 bottom surface of disk, it is down a cylinder at the center of disk, individual pin hole 16 is arranged at cylindrical top, as shown in Figure 4, the upper fork 1 of the utility model design on crossbeam 2, can be beneficial to the arbitrary rotation of sportsman by rotating 360 degrees, reach the angle being applicable to fortune bar, shallow circular hole 8 on upper fork 1 coordinates the collision bead 6 on crossbeam 2 and spring 7 can reach stable upper fork 1 in the tight object of certain angle, the cylinder of upper fork 1 is pierced into by assembling the via hole 14 putting on fork on crossbeam 2 during fork 1, after loading onto spring shim 10, pass the pin hole 16 on cylinder with pin and pin, to reach the object of stable upper fork.

Described crossbeam 2 is strip, the circular via hole 14 putting on fork is provided with in the middle of vertical direction, back cover dell 9 is provided with on via hole 14 side of putting on fork, this hole is not beaten, spring 7 is put into back cover dell 9, spring 7 is put collision bead 6, a via hole 15 fastening fixed fork is respectively established at vertical direction two ends, a step is provided with in the middle of horizontal direction, stubborn handle screw hole 13 is provided with in the middle of step, as shown in Figure 5, spring 7 in back cover dell 9 on crossbeam 2, collision bead 6, shallow round pool 8 in cooperation on fork 1 plays the effect of stable upper fork 1 when fork can be made to be parked in the position of certain angle.

Described fixation fork 3 upper end is a cylinder, pin hole 16 is provided with in cylinder termination, middle part is a step cutting pattern, bottom is flat strip, strip be designed with circular sunk head rivet hole 11 bottom, side, sunk head rivet hole 11 is designed with back cover dell 9, loads onto spring 7 and collision bead 6 in this dell, and the shallow round pool 8 of cooperation activity fork 4 can make movable fork 4 after launching or folding, have the stability of stronger vertical direction.

Described activity fork 4 its shapes are flat elongate strip, one end is designed with sunk head rivet hole 11, shallow round pool 8 is respectively designed with in the both sides in sunk head rivet hole 11, the other end is also designed with sunk head rivet hole 11, back cover dell 9 is designed with on this rivet hole side, spring 7 and collision bead 6 is loaded onto in this dell, coordinate the shallow round pool 8 of next block activity fork 4, do not loosen with the vertical direction stablizing next block activity fork 4, in-line two legs connecting into symmetry of movable fork 4 are set, handle 5 is screwed on stubborn handle screw hole 13, by the cylinder of upper fork 1 through to be through in pin hole 16 with pin after the upper spring shim 10 of pad in the interstitial hole of crossbeam 2 and to pin, by the cylinder of fixation fork 3 through in the via hole 15 fastening fixed fork at crossbeam 2 two ends, pad uses pin hole 16 finger lock after spring shim 10, it is the same that the two ends of crossbeam 4 are installed, as shown in Figure 1.

Action principle of the present utility model is such, the Chinese style assembled is pitched---the billiard ball hack lever of collapsible multistage adjustable double lower support leg height is placed on billiard table, considered according to the position of each ball in scene by sportsman, because only have the bar head of club the closer to Archon, just there is the possibility impacting Archon cambered surface the most accurately, ability score, namely hack lever from Archon more close to better, otherwise hack lever from Archon more away from, the precision that the bar head of club hits the arc sphere of accurate Archon is poorer, the order of accuarcy that the movement locus of rear shock colour ball is opened in Archon motion is poor, open goal is just few.When needing the height reducing upper fork, activity fork is folded up successively, lower support leg will be shortened, upper fork will reduce, if think the position of higher upper fork again, decontrols several activity fork and just equals to increase lower support leg, until after all relieving activity is pitched, the position of upper fork has been exactly the extreme higher position of this Chinese style fork, and the upper fork of the utility model design extreme higher position is much taller compared with the high pin fork used on the market now, and enough sportsmen employ.

The utility model Chinese style is pitched---and the advantage of the billiard ball hack lever of collapsible multistage adjustable double lower support leg height is:

1 equals present low hack lever by when all having folded movable fork.

2 by during whole relieving activities fork higher than present high hack lever.

3 boundaries, between low hack lever and high hack lever, provide the position of the multistage applicable fortune bar height that can adjust, in order to winning victory to sportsman.

4 it be pioneering adjustable hack lever, functionally a bar can push up present three bars with even more, offers convenience, can improve the popularity of this product in the world, win honors for the motherland to user.

5 its upper forks can 360 degree rotations, and adaptation sportsman transports bar, more accurately in order to winning victory.

6 its design are ingenious, and structure is simple, and make easily, cost is low, and use market vast, the whole nation and even the whole world can use, economical and practical.
