Detailed description of the invention
As Fig. 1, ligature molding device of the present invention has a main body bearing 3, connecting rod 31 is provided with in the front center position of this main body bearing 3, one end of regulating arm 6 is connected on connecting rod 31, regulating arm is provided with the several connecting holes 61 distributed along its length, this connecting hole 61 is parallel with connecting rod, wrapping wire post 7 one end is connected in connecting hole, shaping column 4 is connected to the end of connecting rod and parallel relative with wrapping wire post, one end of one upper pressing arm 1 and twice pressure arms 2 is articulated with main body bearing respectively, another free end is respectively equipped with the first groove 111 and the second groove 211 holding shaping column corresponding part.Upper pressing arm and lower pressure arm can rotate about 180 ° around hinged place, when rotating to main body bearing front, free end closes up to shaping column 4, form the slotted eye holding shaping column, refer to Fig. 2, when rotating to main body bearing reverse side, upper pressing arm 1 and twice pressure arms 2 form grip portions, so that the operation before the non-molding of ligature.Flexible member 5 is placed on connecting rod 31, and after the free end of upper pressing arm 1 and lower pressure arm 2 closes up molding to shaping column 4, the elastic force of flexible member 5 struts closing up of free end.
Fig. 2 is the present invention's preferred embodiment, upper pressing arm 1 wherein and lower pressure arm 2 are isometric rod member, and upper pressing arm 1 has vertical bending part 11,21 with the free end corresponding to lower pressure arm 2, and establish 111 and second groove 211 at bending part correspondence first groove be provided with for holding shaping column respectively.The bending part 11 of upper pressing arm 1 is provided with the first groove 111 holding shaping column upper part, and the bending part 21 of lower pressure arm 2 is provided with the second groove 211 holding shaping column lower part.One upper pressing arm 1 and twice pressure arms 2 and the articulated position of main body bearing are distributed on main body bearing center, and to be the center of circle circumferentially same.The connecting rod 31 being arranged on main body bearing 3 front center position is cylindrical bar, connecting rod 31 and the main body bearing 3 of the present embodiment are splits, its one end is connected to (see Fig. 4) on main body bearing 3 by screw 32, the other end is provided with quadrangular 311, one end of regulating arm 6 is provided with the hole suitable with this quadrangular, regulating arm 6 is connected on the quadrangular 311 of connecting rod 31 by this hole, in case regulating arm 6 rotating relative to connecting rod 31, and fixed by holding screw 62, ensure the position location of regulating arm 6.3 substantially equally spaced threaded connection holes 61 are being provided with along the length direction of regulating arm 6, one end of wrapping wire post 7 is provided with corresponding external screw thread, wrapping wire post 7 is spun by the connecting hole 61 on the screw thread of end and diverse location, the parallel distance made it between shaping column changes, form third gear length, to adapt to the length requirement of different ligature.
When ligature 001 is placed on above-mentioned ligature molding device, first upper pressing arm 1 and lower pressure arm 2 is rotated to main body bearing reverse side, form grip portions, convenient operation.Be placed in completely after on shaping column 4 and wrapping wire post 7 at ligature 001, upper pressing arm 1 and lower pressure arm 2 are rotated to main body bearing front, namely 180 ° are rotated, upper pressing arm 1 and lower pressure arm 2 free end is made to press to shaping column, the first groove 111 on free end and the second groove 211 form the slotted eye holding shaping column, be included on ligature, make ligature molding, see Fig. 3.In order to make to be included in upper pressing arm 1 on shaping column and lower pressure arm 2 automatically springs open after to ligature molding, the flexible member 5 of the present embodiment is for being located at the bowl-shape rubber on connecting rod 31, when the free end of upper and lower pressure arm contains shaping column completely, space between upper and lower pressure arm 1,2 and connecting rod 31 is less than radial dimension when this bowl-shape rubber discharges, thus make flexible member 5 produce elastic deformation, complete upper and lower pressure arm compressing to ligature after, upper and lower pressure arm flicks under the effect of flexible member 5.
When upper pressing arm 1 and lower pressure arm 2 free end press to shaping column, twice pressure arm 2 will press to regulating arm 6 simultaneously, is provided with the 3rd groove containing regulating arm corresponding position inside twice pressure arms 2 for this reason, to ensure that the free end motion of upper pressing arm 1 and lower pressure arm 2 puts in place.
The present invention can also carry out alternative formation second embodiment to some structures in above-mentioned embodiment.In the second embodiment, adopt the flexible member 5 be different from the first embodiment scheme, other structures are all identical with the first embodiment, therefore repeat no more.
Flexible member 5 in second embodiment is as Fig. 4, Fig. 5, form primarily of Compress Spring 51 and guide pin bushing 52, Compress Spring 51 is set in corresponding guide pin bushing 52, and one end of a Compress Spring 51 and corresponding guide pin bushing 52 is connected on connecting rod, and corresponds to the radial position of a upper arm 1 or the lower arm of force 2.Guide pin bushing 52 length is less than upper arm 1 or the lower arm of force 2 turns to and connecting rod parallel position time and connecting rod between the radial direction space distance L that formed, and the length of Compress Spring when compression (by) is longer than described space distance L, the end of the Compress Spring be placed in guide pin bushing made is stretched out on the outer and upper arm 1 being compressed on correspondence of guide pin bushing or the lower arm of force 2.When the first groove like this on upper arm 1, the lower arm of force 2 free end or the second groove turn on shaping column, after compressing to ligature 001, Compress Spring does the telescopic variation of radial direction under the guiding of guide pin bushing, by during compression the elastic potential energy of assembling will flick upper and lower pressure arm.
Above-mentioned orthodontic ligature wire shaped device provided by the invention, small and exquisite practicality, and the ligature length of molding can regulate, doctor can select corresponding position to fix wrapping wire post according to the hobby of oneself or different clinical application, be wound in by ligature after on shaping column and wrapping wire post, pressurize upper pressing arm and lower pressure arm molding ligature head simultaneously, takes off wrapping wire post afterwards, ligature afterbody cut off by shears, then can use after taking off ligature.Can an a large amount of ligature of quick Fabrication molding, greatly improve work efficiency.
Described flexible member comprises the guide pin bushing and Compress Spring that are arranged at and connecting rod also correspond to upper pressing arm or lower pressure arm radial position described in one, described guide pin bushing length is less than the distance of the radial direction between described upper pressing arm or lower pressure arm to connecting rod, Compress Spring is set in guide pin bushing, both one end are fixed on connecting rod correspondence position, and the other end of Compress Spring also stretches out outside guide pin bushing.
