Description
Technical field
The present invention relates to the anti-jump needle device in sewing machine technique field, particularly a kind of Sewing machines.
Background technology
Sewing machines is in the sewing process, sewing-machine foot is a very important components, it plays a part two aspects, one is feeding, being about to cloth send forward, with convenient sewing, be cloth to be flattened compress on the other hand, so that eedle is sewed to cloth, because presser feet for feeding, therefore has certain length, just be that this length of feeding that makes things convenient for has made obstacle for its another function, flatten when compressing cloth at presser feet, because some cloth is to be uneven, or the very strong cloth of elasticity, depends merely on presser feet and come cloth flattened that to compress be to be difficult to accomplish, so the bouncing pilotage phenomenon takes place, speed and the quality of considerable influence sewing clothes in the time of will appearing at sewing.
Summary of the invention
Be existing defective and problem in the Sewing machines in the solution prior art, a kind of anti-jump needle device of Sewing machines is provided.
The technical scheme that the present invention adopts for its technical problem of solution is: the anti-jump needle device of a kind of Sewing machines of the present invention comprises presser feet, eedle and eedle fixed bar, the eedle fixed bar is provided with the eedle hold-down nut, eedle is fixed on the eedle fixed bar by the eedle hold-down nut, it is characterized in that, retainer plate on described eedle cover one, last retainer plate lower end connects a spring, and the spring lower end hangs a cloth retainer plate, and described eedle passes retainer plate, spring and cloth retainer plate.
Be provided with one at described eedle and connect salient point, on described, be provided with a J font link slot in the retainer plate, described connection salient point cooperates with J font link slot, and eedle packs into J font link slot by connecting salient point, thereby will go up retainer plate and eedle is fixed together.
Be provided with a line hole at described cloth retainer plate.
Be provided with a circular hole at described presser feet, described circular hole cooperates with the cloth retainer plate, and the cloth retainer plate passes circular hole and moves up and down under moving up and down of eedle drives.
The invention has the beneficial effects as follows: compared with prior art, the anti-jump needle device of Sewing machines of the present invention is with the cloth retainer plate of a band spring at eedle, pass circular hole on the presser feet by the cloth retainer plate, cloth in the space, presser feet below flattened compress, simultaneously eedle passes the cloth retainer plate to the sewing of threading a needle of the cloth of presser feet below, adopt this structure can prevent effectively that the bouncing pilotage situation from taking place, improve speed and the quality of garment production greatly, had advantages such as simple in structure, that result of use is obvious.
Description of drawings
Be described further below in conjunction with the anti-jump needle device of the drawings and specific embodiments to a kind of Sewing machines of the present invention.
Fig. 1 is the perspective view of Sewing machines of the present invention;
Fig. 2 is the STRUCTURE DECOMPOSITION schematic diagram of the anti-jump needle device of Sewing machines of the present invention.
The specific embodiment
As depicted in figs. 1 and 2, the anti-jump needle device of a kind of Sewing machines 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 the 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, be with retainer plate 21 at eedle 20.Be provided with one at eedle 20 and connect salient point 22, in last retainer plate 21, be provided with a J font link slot 23, on connection salient point 22 on the eedle 20 and the last retainer plate 21 and J font link slot 23 cooperate, eedle 20 by connect salient point 22 pack into J font link slot 23 rotate then namely fixing, thereby will go up retainer plate 21 and eedle 20 is fixed together.Last retainer plate 21 lower ends connect a spring 24, and spring 24 lower ends hang a cloth retainer plate 25, and cloth retainer plate 25 matches with circular hole 11 on the presser feet 10, and cloth retainer plate 25 is provided with line hole 26.Last retainer plate 21, spring 24 and cloth retainer plate 25 all are hollow states, and eedle 20 passes retainer plate 21, spring 24 and cloth retainer plate 25.
As depicted in figs. 1 and 2, in use, to go up retainer plate 21, spring 24 and cloth retainer plate 25 and pack into eedle 20 by J font link slot 23, and be fixed on the eedle 20, eedle 20 passes retainer plate 21, spring 24 and cloth retainer plate 25, simultaneously sewing thread is passed line hole 26 on the cloth retainer plate 25 and the line hole on the eedle 20.When Sewing machines is worked, run into up and down two superimposed or scraggly the time, because presser feet has the slit 10 times, therefore eedle 20 is in moving downward, the circular hole 11 that drive cloth retainer plate 25 passes on the presser feet 10 moves downward, the cloth of cloth retainer plate 25 below downward pressing presser feet 10 under the pressure of last retainer plate 21 and spring 24, to make things convenient for eedle 20 to connect up, in the process that behind eedle 20 sutures, moves upward, because the effect of spring 24, cloth retainer plate 25 is with again, by cloth retainer plate 25 moving up and down at circular hole 11, thereby cloth under the presser feet 10 can be driven plain to be compressed, make things convenient for eedle 20 to connect up, thoroughly solved owing to cloth up and down two superimposed or the bouncing pilotage phenomenon that is uneven and causes, eliminated the hidden danger that causes clothes to produce because of bouncing pilotage, had simple in structure, advantages such as result of use is obvious.
, but should be understood that under the situation that does not break away from relevant protection domain defined by the claims that those skilled in the art can make change and/or revise according to embodiments of the invention describing the present invention property and nonrestrictive description.
