The specific embodiment
The present invention will be further described below in conjunction with drawings and Examples.
As shown in Figure 3, needle aid for sewing machine of the present invention, comprise a rigidity or elasticity fabric pressing frame 7, be respectively equipped with tensioning mechanism a and the tensioning mechanism b that is symmetric about two at 7 liang of abutting ends of fabric pressing frame, tensioning mechanism a links to each other by power transmission shaft 4 with tensioning mechanism b; Power transmission shaft 4 is provided with action bars 10, and action bars 10 is connected on the power transmission shaft 4 by steady pin 11; Tensioning mechanism a and tensioning mechanism b run through respectively two earholes 18 and connect a convex connecting base plate 3 that matches with Sewing machines top board projection 17; 7 liang of abutting ends of fabric pressing frame are respectively along fabric pressing frame 7 S-type distributions.Convex connecting base plate 3 structures and sewing machine table top board projection 17 structures are complementary, and connecting base plate 3 links to each other with sewing machine table top board projection 17 by attachment screw 12.
Such as Fig. 4 in conjunction with shown in Figure 5, tensioning mechanism a(tensioning mechanism b structure is with tensioning mechanism a, be oppositely arranged) comprise that the driving member 6 that links to each other with the S type termination of fabric pressing frame 7, driving member 6 are that an end is established indent, the other end and established the metalwork that pin-and-hole, stage casing are established spring steady pin 8; It is coupled that the rigidity of the S type termination of fabric pressing frame 7 or elasticity are compressed into driving member 6 indents, power transmission shaft 4 runs through in the pin-and-hole of driving member 6 and is connected with it, driving member 6 stage casing spring steady pins 8 articulate a back-moving spring 9, back-moving spring 9 other ends are fixed by a pin on the connecting base plate 3, and have certain tightening force, can guarantee trade mark 16 is compressed (as shown in Figure 4) and fabric pressing frame 7 pull-ups (as shown in Figure 6).Power transmission shaft 4 is fixed on the connecting base plate 3 by earhole 18.
Driving member 6 is fixed on the power transmission shaft 4 by steady pin 5, power transmission shaft 4 be empty set in two earholes of connecting base plate 3, allow to rotate with driving member 6, can not move.Two driving members 6 are simultaneously with power transmission shaft about 4 location.
Further specify operation principle of the present invention below by Fig. 7-Fig. 9.
Fabric pressing frame 7 usefulness of the present invention have certain rigidity and elasticity bronze wire or guiding principle silk to bend, and shape is fixed with the trade mark shape size, can be square also can circular, polygon, take not overslaugh sewing as principle.Is clamped in the indent of driving member 6 the tooled joint object 16(trade mark of threading in the framework of fabric pressing frame 7 location in the middle of its two ends S type shape).
As shown in Figure 7, make sewing object 16(trade mark at needs) time, the connecting base plate 3 of convex structure is connected with top board projection 17 contrapositions of sewing machine table by attachment screw 12.Then pull action bars 10, the fabric pressing frame 7 of power transmission shaft 4 anglecs of rotation being adjusted driving member 6 connections lifts, the object 16(trade mark of will sewing) places to sew cloth and need the position of location, adjust power transmission shafts 4 by action bars 10 again and drive the fabric pressing frame 7 that driving members 6 connect and place horizontal impaction state; Fabric pressing frame 7 levels are pressed in sewing object 16(trade mark) on, spring steady pin 8 back-moving springs 9 in driving member 6 stage casings, driving member 6 is positioned at top board 13 top board projection 17 both sides groove in, guaranteed that driving member 6 can freely rotate with respect to power transmission shaft 4, below and back-moving spring 9 that spring steady pin 8 is in turning cylinder 4 place downward-sloping position, as shown in Figure 8.Back-moving spring 9 pulling force make driving member 6 that counter-clockwise rotation trend be arranged below turning cylinder 4, drive the fabric pressing frame 7 object 16(trade mark of will sewing) be pressed on and sew on sewing cloth.
When making sewing object 16(trade mark) make after, Fig. 9 is the diagram with the fabric pressing frame pull-up, pull action bars 10, the fabric pressing frame 7 of power transmission shaft 4 anglecs of rotation being adjusted driving member 6 connections is raised up to the upright position, the spring steady pin 8 in driving member 6 stage casings forwards power transmission shaft 4 tops to and back-moving spring 9 becomes the position that is inclined upwardly, the back-moving spring pulling force makes driving member 6 clockwise rotate trend, driving member 6 is pulled up supreme skewed, until control stick 10 contacts with connecting base plate 3, so far, take out sewn object, finish course of work of the present invention.
The present invention is making sewing object 16(trade mark) time, need according to being sewn sewing object 16(trade mark) thin degree that one sewing machine table backing plate 2(is set between top board 13 and connecting base plate of the present invention 3 is shown in Figure 8).When sewing object 16(trade mark) when thinner, need not pad and establish sewing machine table backing plate 2; When sewing object 16(trade mark) when thicker, need to be according to sewing object 16(trade mark) the thin and thick pad establish the sewing machine table backing plate 2 of different model (this model is set as required by the present invention) so that fabric pressing frame 7 just in time is pressed in sewing object 16(trade mark) on.
Further, the driving member 6 of the present invention or design different length model is produced the servicing unit of the present invention of different model, just can be for thinner sewing object 16(trade mark) take the driving member 6 of the longer model of length; For thicker large sewing object 16(trade mark) take the driving member 6 of the shorter model of length and larger fabric pressing frame 7 to be installed on the power transmission shaft 4.As long as by changing the present invention of different model, just can realize the sewing of different thin and thick trade marks.
