Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in detail.
Consult Fig. 2, the embodiment that the utility model can reduce the badminton frame of windage comprises a connecting rod 3, being connected to one end of this lever 2 for the lever 2, gripped and is formed with through wires hole 41 and is connected to the framework 4 of the other end of this connecting rod 3, and multiple pit 5 being arranged at intervals at this framework 4.
Consult Fig. 3 and Fig. 4, this framework 4 comprises an inner ring surface 42, outer ring surface 43, two and connects lower frame 45, two that this inner ring surface 42 and the joint face 44, of these outer ring surface 43 both sides be connected to this connecting rod 3 is connected to this two side frames portion 46 upper frame 47 from the side frame portion 46 that this lower frame 45 upwards extends and one.The imaginary line being noted that in Fig. 3, Fig. 4 is the boundary line for distinguishing each frame portion.
Consult Fig. 5 and coordinate Fig. 3, this inner ring surface 42 has the interior central area 421 that is formed with aforesaid through wires hole 41, and two border areas, inner side 422 connecting this interior central area 421 and this two joint face 44 respectively.Consult Fig. 6 and coordinate Fig. 3, this outer ring surface 43 have one to should in the outer central area 431 of central area 421, and two are formed at this outer central area 431 both sides and connect the border area, outside 432 of this two joint face 44.As shown in Figures 4 to 6, this this of border area 422 and this outer ring surface 43 outside two on border area 432 inside two that described pit 5 is arranged at intervals at this inner ring surface 42, and do not extend to this two joint face 44.
Consult Fig. 3, for convenience of explanation, in the following description, this inner ring surface 42 is distinguished with 42a, 42b at different frame portions section, and this outer ring surface 43 is distinguished with 43a, 43b at different frame portions section.Consult Fig. 4, in the present embodiment, described pit 5 is only arranged at this two side frames portion 46 and this upper frame 47 of this framework 4, furthermore, described pit 5 is arranged at the inner ring surface 42a in this side frame portion 46, the outer ring surface 43a in this side frame portion 46, and the inner ring surface 42b of this upper frame 47.Wherein, as shown in Figures 5 and 6, each pit 5 corresponds to the position between two adjacent through wires holes 41, and be positioned at this inside two the pit 5 in border area 422 be symmetrical arranged mutually, and be positioned at this outside two the pit 5 in border area 432 be also be symmetrical arranged mutually.
Consult Fig. 3, when installing multiple netting twine 6, outer ring surface 43b due to the upper frame 47 of this framework 4 is recessed to form a groove 471, therefore the netting twine 6 being arranged in the outer ring surface 43b of this upper frame 47 can locally be placed in this groove 471, user can be reduced and drag for ball or this framework 4 when collide with other article, the probability of described netting twine 6 fracture.
Consult Fig. 7 and Fig. 8, time swinging the bat in direction according to arrow B, a turbulent wake zone 17 can be formed at leeward side 16 equally by the air-flow of the windward side 15 of this framework 4, and due to the flow direction that can change air-flow that arranges of described pit 5, the scope of this turbulent wake zone 17 can be reduced, therefore effectively can reduce windage, promote speed of swing.
In sum, the badminton frame that the utility model can reduce windage, by the configuration design of described pit 5 on this framework 4, when user swings the bat, can reduce the impact of windage on this framework 4, promote the speed of swinging the bat.
