Abstract
The invention relates to the technical field of sewing machines and particularly relates to an auxiliary device of the sewing machine. Compared with the prior art, the auxiliary device of the sewing machine comprises a pressing pin, a needle and a needle fixed rod, wherein a needle fixed nut is arranged on the needle fixed rod; the needle is fixed on the needle fixed rod through the needle fixed nut; an upper fixed ring sleeves the needle; the lower end of the upper fixed ring is connected with a spring; a cloth fixed ring is hung at the lower end of the spring; the needle penetrates through the fixed ring, the spring and the cloth fixed ring and passes through the cloth fixed ring to penetrate through a round hole in the pressing pin, and cloth in a gap under the pressing pin is tightly pressed; meanwhile, the needle penetrates through the cloth fixed ring to sew the cloth under the pressing pin; with the adoption of the structure, a stitch skipping condition can be effectively prevented, and the speed and quality of producing clothes are greatly improved; and the auxiliary device of the sewing machine has the advantages of simple structure, obvious use effect and the like.
Description
Technical field
The present invention relates to sewing machine technique field, particularly a kind of sewing machine auxiliary device.
Background technology
Sewing machines is in sewing process, sewing-machine foot is very important parts, it plays a part two aspects, one is feeding, send forward by cloth, to facilitate sewing, carry out pressing to cloth to compress on the other hand, so that eedle is sewed to cloth, because presser feet is in order to feeding, therefore there is certain length, just that this length of feeding that facilitates has manufactured obstacle to its another function, when presser feet carries out pressing compression cloth, because some cloth is uneven, or the cloth that elasticity is very strong, depending merely on presser feet, to carry out pressing compression to cloth be difficult to accomplish, so there is bouncing pilotage phenomenon when just appearing in sewing, the speed of considerable influence sewing clothes and quality.
Summary of the invention
For solving defect existing in Sewing machines in prior art and problem, provide a kind of sewing machine auxiliary device.
The technical scheme that the present invention adopts for its technical problem of solution is: a kind of sewing machine auxiliary device of the present invention comprises presser feet, eedle and eedle fixed bar, eedle fixed bar is provided with eedle hold-down nut, eedle is fixed on eedle fixed bar by eedle hold-down nut, it is characterized in that, described eedle overlaps retainer plate on, upper retainer plate lower end connects a spring, and lower spring end hangs a cloth retainer plate, and described eedle is through upper retainer plate, spring and cloth retainer plate.
Described eedle is provided with a connecting salient points, a J-shaped link slot is provided with in described upper retainer plate, described connecting salient points coordinates with J-shaped link slot, and eedle packs into J-shaped link slot by connecting salient points, thus upper retainer plate and eedle is fixed together.
Described cloth retainer plate is provided with a string holes.
Described presser feet is provided with a circular hole, and described circular hole coordinates with cloth retainer plate, and cloth retainer plate moves up and down through circular hole under the drive that moves up and down of eedle.
The invention has the beneficial effects as follows: compared with prior art, sewing machine auxiliary device of the present invention has a cloth retainer plate being with spring at eedle cover, by cloth retainer plate through the circular hole on presser feet, carry out pressing to the cloth in presser feet gaps underneath to compress, simultaneously eedle to be threaded a needle sewing to the cloth below presser feet through cloth retainer plate, this structure is adopted can effectively to prevent bouncing pilotage situation from occurring, substantially increase speed and the quality of garment production, there is the advantages such as structure is simple, result of use is obvious.

Fig. 2 is the STRUCTURE DECOMPOSITION schematic diagram of sewing machine auxiliary device of the present invention.
Detailed description of the invention
As depicted in figs. 1 and 2, a kind of sewing machine auxiliary device of the present invention comprises presser feet 10, eedle 20 and eedle fixed bar 30.Eedle fixed bar 30 is provided with eedle hold-down nut 31, and eedle 20 is fixed on eedle fixed bar 30 by eedle hold-down nut 31, and presser feet 10 is provided with a circular hole 11.
As depicted in figs. 1 and 2, on eedle 20, cover has retainer plate 21 on.Eedle 20 is provided with a connecting salient points 22, a J-shaped link slot 23 is provided with in upper retainer plate 21, connecting salient points 22 on eedle 20 coordinates with J-shaped link slot 23 with on upper retainer plate 21, eedle 20 packs into J-shaped link slot 23 by connecting salient points 22 and then rotates and namely fix, thus is fixed together with eedle 20 by upper retainer plate 21.Upper retainer plate 21 lower end connects a spring 24, and spring 24 lower end hangs a cloth retainer plate 25, and cloth retainer plate 25 matches with the circular hole 11 on presser feet 10, and cloth retainer plate 25 is provided with string holes 26.Upper retainer plate 21, spring 24 and cloth retainer plate 25 are all hollow states, and eedle 20 is through upper retainer plate 21, spring 24 and cloth retainer plate 25.
As depicted in figs. 1 and 2, in use, upper retainer plate 21, spring 24 and cloth retainer plate 25 are packed into eedle 20 by J-shaped link slot 23, and be fixed on eedle 20, sewing thread, through upper retainer plate 21, spring 24 and cloth retainer plate 25, is passed the string holes 26 on cloth retainer plate 25 and the string holes on eedle 20 by eedle 20 simultaneously.When Sewing machines works, run into upper and lower two superimposed or scraggly time, because presser feet has gap 10 times, therefore eedle 20 is in moving downward, cloth retainer plate 25 is driven to move downward through the circular hole 11 on presser feet 10, cloth retainer plate 25 flattens the cloth below presser feet 10 downwards under the pressure of upper retainer plate 21 and spring 24, connect up to facilitate eedle 20, after eedle 20 suture in motion process, due to the effect of spring 24, cloth retainer plate 25 is brought again, by cloth retainer plate 25 moving up and down at circular hole 11, thus enable the cloth under presser feet 10 be driven plain compression, eedle 20 is facilitated to connect up.
