Consult Fig. 1-Fig. 5, the utility model golf practice device includes: a bracing frame 1, one bearing holder (housing, cover) 2, one connecting rods, 3, one golf 4 and a display 5.

This bracing frame 1 can be the L type, comprise: a level frame 11, one vertical rack 12 is orthogonal to this level frame 11, but a base 13 is positioned at bottom mat screw (bolt, the 14) lock of vertical rack 12 to be connected on the base wad 10, and a jointed shaft 15 is derived to connect a horizontal bearing (16 from level frame 11, as ball bearing etc.), bearing 16 mats are inserted quiet 17 and are installed on the hinge 15, and most prominent pearl or prominent ring 18 be based on level frame 11 end walls, to touch this bearing holder (housing, cover) 2 rotatably.

This bearing holder (housing, cover) 2 comprises: a universal drive shaft pod 21, with 3 li on the connecting rod of spinning universally (on) the spherical axle core 31 of end, (encircle between the prominent pearl of universal drive shaft pod 21 and level frame 11 end walls with a trunnion axis pod 22,18) between, to screw the horizontal bearing 16 on this level frame 11, this bearing holder (housing, cover) 2 is rotated along trunnion axis X.This bearing holder (housing, cover) 2 can be covered with bearing holder (housing, cover) end wall 23 in next-door neighbour's level frame end, and its central authorities offer axis hole with the jointed shaft 15 that spins.

Certainly, as Fig. 2, shown in Figure 3, this bearing holder (housing, cover) 2 can be by upper half shell 2u and lower half shell 2d mat screw (bolt, 20) be combined in addition; Upper half shell 2u contains the contained bottom half-bearing nest 21d of first spindle socket 21u and lower half shell 2d this spherical axle core 31 of universal hinging in the lump, makes this pitman shaft core 31 can universal hinging rotation in this universal drive shaft pod 21u, 21d; Second alcove 22d that the contiguous level frame 11 of upper half shell 2u still is concaved with first alcove 22u and lower half shell 2d constitutes this trunnion axis pod 22u, 22d in the lump, with hinged this horizontal bearing 16.

A bar hole 21w is offered in these bearing holder (housing, cover) 2 belows, and its width (or diameter) is less than the diameter of this core 31, and the bar peritreme can put rubber ring 21p, to receive the anti-effect that hits on-slip.

Relevant horizontal bearing 16 has one at least, but also can be provided with a plurality of.The prominent pearl of bearing holder (housing, cover) 2 and level frame end face or prominent ring 18 makes point-like or ring-type touches, the circle that helps bearing holder (housing, cover) 2 is clockwise moving, and increases bearing holder (housing, cover) 2 hinges and be loaded on stability on the level frame 11.

As shown in Figure 7, this bearing holder (housing, cover) 2 has been modified to spherical bearing holder (housing, cover) 2, makes its quality lighter, and windage loading is littler.But shape, the structure of each element of the utility model do not add restriction.

This connecting rod 3 is by shown in Figure 4, though can increase progressively its bar footpath one by one from spherical axle core 31, the thickest person who holds until down (outer), but the utility model does not limit the bar footpath diameter variation of its gradient type (degradational), the shape on bar surface, moulding or tip hole (number 351 as Fig. 4,352,353) structure is not limited yet, and in addition suitably changes in modification is used.

This connecting rod 3 comprises: one spherical core 31 is to make hollow 311, manifesting relatively is centrifugal force when being connected in golf 4 rotation of connecting rod outer end, one li (on) bar portion 32 these cores 31 of connection, bar portion 32 in one king-rod portion, 33 diameters are a bit larger tham, one 34 outer this king-rod portions 33 that connect of prominent rib bar portion, its cross section has most prominent ribs 341 and trench 342, so that mat convex-concave structure increases the shock-absorbing and the reinforcing effect (for example can resist or cushion beginner's club head mistake and hit this connecting rod position) of connecting rod, and adjustable outer (descending) bar portion 35, offer most tips hole 352 on it, so that mat pin 44, packing ring 43 is installed in this outer bar portion 35 with golf 4.

Bar portion

32,33,34,35 and axle core 31 can one-body moldedly be made.

When golf 4 is to be connected on the connecting rod 3, after batting, if directly advance (straight) formula, then ball 4 rotates around horizontal axis X with connecting rod 3; The ball if take back (hook) then connecting rod 3 will be the track H shown in the right-hand dotted line of Fig. 1; The ball if take over (slice) then is the track S shown in Fig. 1 left dotted line, and (lining) end axle core 31 of going up of connecting rod is can universal rotation in bearing holder (housing, cover) 2, when it runs into bar hole 21w hole wall, one by one and connect (connection) moving this bearing holder (housing, cover) 2 and rotate around axle X, but the bar axle center Y of connecting rod 3 then can be orthogonal to horizontal axis X or be deflection angle (as H or the S of Fig. 1) with it, and present the deflection curve then can " judgement ", detect the directionality of hitter's batting, increase the interest of practising a ball game increasingly, and promote the efficient of practising a ball game, the progress that helps playing skill is with consummate, and this also is to be the utility model excellence, progressive in the place of traditional golf practice device.

About consolidating of golf 4 and connecting rod 3 is that mode can be consulted Fig. 4, shown in Figure 5.Adjustable outer bar portion 35 is made by outer (descending) bar portion 35 of this fortune bar, being horizontally set with most tips hole 351 and limit groove 352 on it is arranged with on the bar wall, so that the straight taper of modern folder formula pin 44 441 inserts tip hole 351, and the limit that makes folder formula pin 44 presss from both sides 442 chucks in the limit of bar wall groove 352, by packing ring 43 golf 4 is lain in the outer bar portion 35 of connecting rod admittedly.

This golf 4 contains: a bar hole 41, so that wear outer bar portion 35, the one hollow alcoves 42 of connecting rod, be arranged with in golf 4, and be that golf 4 is on connecting rod 3, especially as shown in Figure 5 admittedly so that be inserted in packing ring 43 mat pins 44.Can vertically dash forward in the outer bar of this connecting rod 3 portion 35 and establish a protruded stigma 351, make golf clubs hole 41 indents, one pothole 411, and make packing ring bar hole 431 indents, one recess 432, so that the protruded stigma 351 of the outer bar that coincide, after plugging in folder, solid system, can prevent turning round partially of golf 4 by pin 44; Also be after golf 4 is hit, can deflection, axle core 31 bands that directly are passed to the bar inner end after stressed change connecting rods 3, can the capable track of " verily " reflection batting back ball.

As shown in Figure 6, these 35 vertical indents of connecting rod 3 outer bar portions are pothole 351a, the bar hole 41 that makes golf accordingly is to the radially inside exsule protruded stigma 411a in center, bar hole, make packing ring bar hole 431 also inwardly stretch a lug 432a in the footpath, pothole 351a with the outer bar portion of this connecting rod of coincideing, owing to be concavo-convex engaging, after lock is pin 44, can firm, golf 4 be installed on the connecting rod 3 with turning round partially.

The utility model still can be on bracing frame 1, in the end opposite of golf 4, connecting rod 3, be connected with a display (5, display) to show the rotating speed of square stance, or being scaled the data such as strength of batting, this can be designed, be used it by the personnel that are skillful in this technology.And also can be equipped with scale or mark on level frame 11 and bearing holder (housing, cover) 2 region of interest, with the rotating speed after the counting batting, because of it belongs to conventional art, so do not give unnecessary details.
