The specific embodiment

See also Fig. 1 to Fig. 4, the car needle device of quick threading provided by the present invention, mainly include: a needle stand 1, an one car pin 2 and a threading apparatus 3, wherein, this needle stand 1 joins with the connecting rod 9 of sewing machine equipment, this connecting rod 9 axially is concaved with a guide channel 91, so that sewing machine equipment by this this needle stand 1 of connecting rod 9 stoppers along the reciprocal start of vertical direction, this needle stand 1 leading edge indent forms a yarn guide channel 11, and this needle stand 1 trailing edge forms a catching groove 13 and a draw-in groove 15, these draw-in groove 15 corresponding guide channels 91 that are communicated with, this needle stand 1 is established a purl device 12 in the side direction lock in addition, these car pin 2 top axles insert in this needle stand 1, and rely on this purl device 12 side direction to lock, this car pin 2 wears a through wires hole 21 (shown in Fig. 2 A) in place, contiguous bottom, with by this yarn guide channel 11 to these car pin 2 bottom direction guiding wire rods, and make wire rod be connected to this car pin 2 by this through wires hole 21.

This threading apparatus 3 and this needle stand 1 movable pivot joint, this threading apparatus 3 makes for plastics penetrate, nonmetal be processed into or metal metal plate material is processed into, mainly constitute by an erect type fishplate bar 31, a shield 32 and a line hook 33, wherein, this fishplate bar 31 is a long shaped plate axon inserts in a draw-in groove 15 from this needle stand 1 to pivot, and this fishplate bar 31 is adjacent with this car pin 2, and this shield 32 crosses at this fishplate bar 31 bottom leading edges.Shown in Fig. 2 B, these fishplate bar 31 both sides are convexly equipped with that two

auricles

34,35 are adjacent with this shield 32 apical margins, and this shield 32 wears a crossed beam trunking 322, and this crossed beam trunking 322 also extends to form a guide pin slot 324 to these fishplate bar 31 directions.

Shown in Fig. 4 A, this line hook 33 is suspended at these fishplate bar 31 leading edges and is positioned at this place, guide pin slot 324 tops, and this line hook 33 forms open crotch body (this line hook 33 also can form open crotch body in apical margin) in root edge, these car pin 2 hypomeres extend through this crossed beam trunking 322, the leading edge face of these fishplate bar 31 contiguous bottoms is convexly equipped with a locating button 312, this needle stand 1 trailing edge catching groove 13 that caves in is according to making these locating button 312 buckles in this catching groove 13, for this threading apparatus 3 of location.

Shown in Fig. 2 and Fig. 4 B, the rear surface of these fishplate bar 31 adjacent top end is convexly equipped with a protuberance 314, and this needle stand 1 inside forms a flange 14 in these fishplate bar 31 trailing edge adjacents.In view of the above, when this threading apparatus 3 formed the threading mode of operation to bottom offset, 14 pairs of these protuberances of this flange 314 form placed restrictions on, and located this line hook 33 with this and formed relative status with this through wires hole 21,, operate back and forth by these through wires hole 21 hook backguy materials for this line hook 33 with the threading of this car pin 2 that carries out.

As Fig. 5 to the fast auxiliary threader that Figure 8 shows that second embodiment of the invention, this connecting rod 9 is a hollow rod shape, its connecting rod 9 bottom inner edges are provided with a fixed body 93, this fixed body 93 axially is provided with a guiding incline 931, this fixed body 93 more is formed with a circular arc 932 in the top of guiding incline 931, after inserting fixed body 93, connecting rod 9 bottoms of sewing machine equipment can join with needle stand 1 again, this needle stand 1 trailing edge forms a catching groove 13 and a draw-in groove 15, these draw-in groove 15 corresponding spaces 94 that are communicated with connecting rod 9 inner edges and guiding incline 931, when the draw-in groove 15 that inserts in this needle stand 1 when the fishplate bar 31 axial pivots of threading apparatus 3 moves up and down, the guiding incline 931 and the circular arc 932 of this fixed body 93 can provide the effect of guiding fishplate bar 31, according to make sewing machine equipment by this this needle stand 1 of connecting rod 9 stoppers along the reciprocal start of vertical direction, the space 94 of these connecting rod 9 inner edges and guiding incline 932 can limit threading apparatus 3 fishplate bar 31 in case stop bit move.As shown in Figure 9, these connecting rod 9 tops are provided with a stiff end 95, it can collude on the fishplate bar 31 of being located at stiff end 95 and threading apparatus 3 with a spring 96, and this threading apparatus 3 can upwards be passed via this spring 96 it is resetted, and can rely on these spring 96 in good time restriction fishplate bars 31 to rock simultaneously.

When desiring to make wire rod to pass this through wires hole 21 with these car pin 2 cross-under, at first utilize the elastic properties of materials of this fishplate bar 31, these fishplate bar 31 bottoms are partly pulled backward a little, make this locating button 312 break away from this catching groove 13, this threading apparatus 3 can be to bottom offset, form Figure 10, state shown in Figure 11, at this moment, the effect of placing restrictions on (as Figure 11 A) by 14 pairs of these protuberances 314 of this flange, located this threading apparatus 3, avoid these threading apparatus 3 slippages to leave this needle stand 1, and make this line hook 33 and this through wires hole 21 relative (shown in Figure 10 A);

Then, shown in Figure 12 and Figure 12 A, be set in the wire rod 92 of this car pin 2 by these yarn guide channel 11 these car pin 2 bottoms of guiding and this shield 32 directions with desiring, and wire rod 92 is walked around auricle 34 trailing edges of these fishplate bar 31 1 sides by these fishplate bar 31 leading edges, pull out and walk around this car pin 2 leading edges by these auricle 34 root edges, walk around this auricle 35 trailing edges by another auricle 35 root edges again, and forwards draw, this fishplate bar 31 and this car pin 2 are formed by the state of this wire rod 92 around knot by these auricle 35 apical margins;

Then, shown in Figure 13 and Figure 13 A, with this wire rod 92 by these auricle 35 apical margins application of force drawing forward, by the contained effect of this wire rod 92 and the elasticity of this fishplate bar 31, make this fishplate bar 31 bottoms partly to these car pin 2 directions by moving, this car pin 2 is also relative approaching with this fishplate bar 31 by the guiding of this guide pin slot 324, and this line hook 33 then passes this through wires hole 21 and stretches out to the place ahead of this car pin 2, makes this this wire rod 92 of line hook 33 clasp joints;

Then, shown in Figure 14 and Figure 14 A, unclamp the drawing application of force to this wire rod 92, this fishplate bar 31 is satisfied and is relied on itself elasticity and rearward reset, 33 on this line hook is when withdrawing from this through wires hole 21, this wire rod 92 bands are drawn pass this through wires hole 21, at last, as shown in figure 15, this threading apparatus 3 upwards passed it is resetted, this wire rod 92 root edges and 33 unhook of this line hooks by this line hook 33, promptly accuse and finish the operation of car pin threading, then, then with wire rod 92 in yarn guide channel 11 spacing crossed beam trunkings 322 at shield 32, can start sewing machine equipment, make needle stand 1, car pin 2 and threading apparatus 3 can follow connecting rod 9 along the reciprocal start of vertical direction synchronously, begin to carry out follow-up sewing or car embroidery art and do, and spacing wire rod 92 in crossed beam trunking 322 can not swung arbitrarily in the process of sewing or car embroidery, as shown in figure 16.

In view of the above, the present invention can be easily and apace wire rod is arranged in the car pin, and can effectively improve the convenience of threading, and in the process that threading carries out, covers by these shield 32 formation, and the needle point of avoiding pointing by the car pin is stabbed, and threading is safe.

The above description of this invention is illustrative, and nonrestrictive, and those skilled in the art is understood, and can carry out many modifications, variation or equivalence to it within spirit that claim limits and scope, but they will fall within the scope of protection of the present invention all.
