Description
Technical field
The utility model relates to a kind of racket threader, relate in particular to a kind of make racket string can dogging to the bottom of turntable, make two racket fixtures move the improved racket threader of adjusting distance simultaneously.
Background technology
As shown in Figure 6, be a kind of existing racket threader, it mainly is to be provided with a rotatable rotary platform 71 on a pedestal 7, this pedestal 7 is provided with an anchoring 72 in order to control racket string degree of tightness in a side of this turntable 71, this turntable 71 is provided with two support arms 81, the top of each support arm 81 is respectively equipped with a racket fixture 8, for fixing a racquet frame.
Because this racquet frame has the branch of size, for example the racquet frame of tennis racket and racket varies in size, so this support arm 81 must move on turntable 71, to adjust the distance of 8 of two racket fixtures, with the racquet frame that are applicable to that difference is big or small.Aforementioned existing racket threader, as shown in Figure 7, it is to be provided with two chutes 711 on this turntable 71, establish this support arm 81 for sliding respectively, the bottom of this support arm 81 has a screw 82, and a bolt 83 is upwards stretched through by the bottom of this turntable 71 and is locked in the screw 82 of this support arm 8 behind this chute 711, and the cross bar 84 that stretches through in the bottom of this nut 83, rotate these nuts 83 to push against by this cross bar 84 in the bottom of turntable 71, and fix this support arm 81, or unscrew this bolt 83, make this support arm 8 removable, to adjust the distance of 8 of two racket fixtures.
Yet this two support arm 81 is to adjust separately respectively to move, as shown in Figure 8, therefore in the distance of adjusting 81 of two support arms, when making this racket fixture 8 fix this racquet frame 9, this racquet frame 9 is difficult for being fixed in the center 712 of these turntable 71 rotations, especially when the racquet frame 9 of different sizes is replaced, because 81 displacements of two support arms are longer, make the racquet frame 9 more difficult pivots 712 that are fixed on this turntable 71, even can be offset from a side of this turntable 71, thus, when turntable 71 in rotation during threading, when this turntable 71 rotated to major axis or minor axis location, this racquet frame 9 to the distance of this anchoring 72 can constantly change, the backguy distance of anchoring 72 is constantly changed, and cause the poundage inequality of each racket string stay bolt of this racquet frame 9.
Moreover, though this cross bar 84 is positioned at the bottom of turntable 71, but this turntable 71 rotates on pedestal 7, therefore when turntable 71 rotates threading, the cross bar 84 of these turntable 71 bottoms can outer expose outside, make the rotation frequently of the racket string that is not through at as yet on the racquet frame, and be hooked to this cross bar 84, cause difficulty and inconvenience at threading because of turntable 71.

The specific embodiment
See also Fig. 1 to Fig. 3. shown in, the improved racket threader of the utility model, be on a pedestal 1, to be provided with a rotatable rotary platform 2, this pedestal 1 is provided with an anchoring 3 in order to control racket string degree of tightness in a side of turntable 2, this turntable 2 in the present embodiment, be to be the disk body 21 of sealing shaped as frame by three long rectangles and minor axis cross section, admittedly form with the side of its major axis spiral shell connected with each other, the end face of disk body 21 is offered two chutes 22 respectively at the two ends of its major axis in the middle of this turntable 2, for a upwardly extending support arm 41 is set respectively, each support arm 41 be by a mobile device 5 drive simultaneously along each chute 22 direction relative near with away from moving, and the top of each support arm 41 is respectively equipped with a racket fixture 4, supplies fixedly racquet frame.
This mobile device 5 is located at the bottom of this turntable 2, in the present embodiment, this mobile device 5 is located at the inside of the disk body 21 in the middle of this turntable 2, this mobile device 5 has a driving member 51 and two moving members 52, this driving member 51 has the thread segment 511 of the two different hands of spiral, in the present embodiment, this driving member 51 is one to have the screw rod of two sections different hands of spiral, and each thread segment 511 is established for these moving member 52 spiral shells respectively.Drive by the rotation of this driving member 51, make this moving member 52 can be in the inside of the disk body 21 in the middle of this turntable 2 relative near with away from moving, and the two ends of this driving member 51 are located in the two ends of the disk body 21 of these turntable 2 centres respectively.The two ends of this driving member 51 extend to disk body 21 outsides respectively and are provided with a knob 512, for this driving member 51 of turn, the end face of each moving member 52 protrudes out a protruding rail 521 respectively to each chute 22 that should disk body 21, for stretching out this chute 22 and being fixed at the bottom of the support arm 41 of this racket fixture 4.
Be provided with guide member between the bottom of this moving member 52 and turntable 2, move for this moving member 52 of guiding, in the present embodiment, this guide member is the guide groove 522 that is respectively equipped with several tool taperings in the end face of this moving member 52 and bottom surface, top, the bottom surface of corresponding each guide groove 522 are respectively equipped with the guide rail 211 that matches with this guide groove 522 taperings in this disk body 21, move in disk body 21 for this moving member 52 of guiding.
Whereby, adjust the distance of 5 of two support arms, 41 top racket fixtures, when fixing this racquet frame, as shown in Figure 4, it is to rotate this knob 512 to drive this driving member 51 rotations, because two thread segments 511 of this driving member 51 have the screw thread of different directions respectively, therefore, each moving member 52 is moved to the centre simultaneously, and then make each support arm 41 drive this racket fixture 4 simultaneously to move, to fix this racquet frame to the centre.
Because two thread segments 511 of this driving member 51 have the screw thread of different directions respectively, make that each moving member 52 can be simultaneously close to the centre, and racquet frame 6 is fixed in the pivot of this turntable 2, as shown in Figure 5, no matter and the size of racquet frame 6 all is fixed in the pivot of this turntable 2, no matter and when making racquet frame 6 turntables 2 rotate to major axis or minor axis location, it is all identical with backguy distance between this anchoring, and make the stay bolt poundage of the racket string that racquet frame 6 worn all identical.
Moreover, because this moving member 52 and the guide rail 211 that the contact-making surface of this disk body 21 is respectively equipped with several guide grooves 522 and matches can be guided moving of this moving member 52, make moving of this moving member 52 more smooth and easy.And this guide groove 522 has the tapering that matches with this guide rail 211, because when threading, the support arm 41 of this racket fixture 4 is subjected to the strength of backguy and contracts closely to the centre, the movable block 52 that makes these support arm 41 bottoms relatively away from an end perk, when threading was finished the disappearance of tension strength, this moving member 52 made the position of moving member 52 correctings in this disk body 21 because of the tapering that guide groove 522 and this guide rail 211 match, and can not hold disk body 21, two moving members 52 can smooth and easyly be moved.
In addition, this mobile device 5 is disk body 21 inside of being located in the middle of this turntable 2, and can not expose to the bottom of this turntable 2, so this turntable 2 is when the rotation threading, racket string can dogging to the bottom of turntable 2, and can not influence the action of threading.
