The specific embodiment
For let above-mentioned purpose of the present invention, feature and advantage can be more obviously understandable, elaborate below in conjunction with the accompanying drawing specific embodiments of the invention.Need to prove that at first the present invention is not limited to the following specific embodiment, those skilled in the art should understand the present invention from the spirit that following embodiment embodied, and each technical term can be done the most wide in range understanding based on spirit of the present invention.Same or analogous member uses the same reference numerals to represent among the figure.
Consult Fig. 3, Fig. 4 and Fig. 5; The bat in the replaceable strike district of a preferred embodiment of the present invention comprises one and hits 2, cervicals part of esophagus of section 3, one and go up handle section 4, lower handle section 5, socket unit 6, a locking unit 7 and an enhanced tube 8.
This strike section 2 is along an axis X extension and form strike district 21 (see figure 6)s that several are positioned at outer peripheral face.
This cervical part of esophagus 3 is extended along this axis X direction external diameter by these strike section 2 one ends degressively.
Should go up handle section 4 and extend along this axis X direction, and comprise a bottom 41 that outline is rounded by these cervical part of esophagus 3 ends.
In the present embodiment, this hits section 2, this cervical part of esophagus 3 and should go up the member that handle section 4 is extended for one, and material can be selected common wood or aluminium alloy for use.
This lower handle section 5 is another individual member; Material can select for use plastic cement to strengthen chemical fibre dimension (FRP); Handle section 4 is oppositely arranged along this axis X direction this lower handle section 5 with being somebody's turn to do upward; And comprise an outline be equal to the top ends 51 of this bottom 41, one in contrast to the bottom of this top ends 51 52, holding section portion with this top ends 51 53, a handle head 54 with this bottom 52, and one with this axis X crossing extended surface 9 that tilts.
In 10.16 to 17.78 centimetres of length circle of this holding section portion 53 (4 to 7 inch) are fit to being hold by one hand of general adult, and the cross section ovalize (see figure 7) of an end of contiguous this handle head 54.
This handle head 54 is provided with along this extended surface 9; And have a top surface of ring 541 that is positioned at these extended surface 9 one sides and connects these holding section portion 53 outer peripheral faces, a ring bottom surface 542 that is positioned at these extended surface 9 opposite sides, and ring neck face 543 that connects this top surface of ring 541 and this ring bottom surface 542.It is planar that this top surface of ring 541 and this ring bottom surface 542 are convex arc respectively, and it is planar that this ring neck face 543 is concave arc.
Cooperate and to consult Fig. 7, in the present embodiment, these extended surface 9 ovalizes, and have the vertical minor axis 92 of a major axis 91 and and this major axis 91, this major axis 91 is to tilt crossing with this axis X.This holding section portion 53 corresponding to the size of these major axis 91 directions greater than the size of this holding section portion 53 corresponding to these minor axis 92 directions.
This socket unit 6 comprises a bottom 41 by handle section 4 on this along the linearly extended connecting rod 61 of this axis X direction, and one by the top ends 51 of this lower handle section 5 towards these bottom 52 extensions and shape corresponding to this connecting rod 61 and supply the ccontaining sleeve joint hole 62 of this connecting rod 61.
This connecting rod 61 has one and is connected in handle section 4 and the rounded straight-bar portion 611 of cross section on this, and a location division 612 that connects this straight-bar portion 611.
Cooperate and consult Fig. 6; The shape of cross section of this location division 612 has at least two straightways 613 and with respect to this axis X symmetry, in the present embodiment, these location division 612 cross sections are square; Purpose is this strike section 2 to be subdivided into four hit district 21; Can certainly this location division 612 be varied to regular hexagon or octagon and hit district 21, likewise, also can reduce and hit district 21 to increase.
This sleeve joint hole 62 has a straight hole portion 621 that supplies this straight-bar portion 611 to wear, and reaches this straight hole portion 621 of connection and the shape of cross section spacing hole portion 622 corresponding to these location division 612 shape of cross sections.
This locking unit 7 comprises that one is communicated with the locking hole 71 of this sleeve joint hole 62, stop surface that is positioned at these locking hole 71 outsides 72, a locking part 73 along this axis X direction, and a nut 74 that is embedded in this location division 612.
This locking part 73 has a bar portion 731 that is extended through this locking hole 71 and is fixed in this connecting rod 61, and a head 732 that is resisted against this stop surface 72, and in the present embodiment, this locking part 73 is that a screw lock is in the bolt of this nut 74.
This enhanced tube 8 is hollow tubular; And extend and be embedded in handle section 4 this on, this cervical part of esophagus 3 and this strike sections 2 along this axis X direction; This connecting rod 61 is hollow tubular, and in the present embodiment, this enhanced tube 8 is to process so that the carbon fiber material is one-body molded with this connecting rod 61.
Consult Fig. 5 and Fig. 6; One of them of hitting section 2 when this is when to hit district 21 because of long-term bump impaired; Can earlier this locking part 73 be separated the nut 74 that is positioned at this connecting rod 61, again this location division 612 pulled away this spacing hole portion 622 and rotates this lower handle section 5, the strike district 21 that makes another desire use is corresponding to after these major axis 91 directions; Again this location division 612 is plugged in this spacing hole portion 622, and this locking part 73 is locked in this nut 74 just accomplishes replacing.
Generally speaking; The present invention is square by the cross section of the location division 612 of this connecting rod 61, and cooperates this spacing hole portion 622 to be fixedly arranged in this lower handle section 5 with this locking unit 7, not only can change said strike district 21 according to demand; Also can not increase the gripping external diameter of this lower handle section 5 and conveniently grip the application of force; Moreover, utilize this enhanced tube 8 and this connecting rod 61 to process so that the carbon fiber material is one-body molded, and extend be embedded in this strikes sections 2, this cervical part of esophagus 3, on this in handle section 4 and this lower handle section 5; Making the present invention also have increases the effect of hitting intensity and durability, so can reach the object of the invention really.
What deserves to be mentioned is, though in the present embodiment, this lower handle section 5 has the shape that is asymmetric with this axis X; But, still can be applicable to the present invention, in addition if adopt the shape that is symmetrical in this axis X fully; This connecting rod 61 also can not be provided with this straight-bar portion 611, and all length is this location division 612, and 62 of this sleeve joint holes cooperate this connecting rod 61 that this straight hole portion 621 is not set; All the degree of depth is this spacing hole portion 622, also can reach the object of the invention.
Should be understood that after having read above-mentioned teachings of the present invention, those skilled in the art can do various changes or modification to the present invention, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
