Abstract
The utility model belongs to the field of sewing machines and particularly relates to a thread take-up lever for a sewing machine. The thread take-up lever comprises a thread through hole boss, a linkage, a cylindrical connector and a sliding rod. The sliding rod is fixedly connected with the cylindrical connector, an oil injection port is formed in the upper end of the cylindrical connector, one end of the linkage is fixedly connected with the cylindrical connector, and the other end of the linkage is fixedly connected with the thread through hole boss. A first thread through hole and a second thread through hole are formed in the thread through hole boss, and the central connection line of the first thread through hole and the second thread through hole is parallel to the sliding rod. According to the thread take-up lever, the thread take-up stroke is large, and by means of the large-stroke take-up lever structure, the attractiveness of stitches during sewing and sewing thread taking up can be improved, bad stitches are decreased, and the work efficiency is improved.
Description
Technical field
The utility model belongs to sewing machine field, is specifically related to a kind of use in sewing machine thread take-up tension lever.
Background technology
On Sewing machines, the effect of thread take-up tension lever is in each work period of stitching forming process, controls thread take-up tension lever supply and reclaims appropriate upper thread, and the stitching that upper thread and bottom line are formed tightens up, and extracts a needed line amount of using of stitching out from spool.Current multiplex slide bar type thread take-up tension lever on Sewing machines, when this thread take-up tension lever is made take-up, stitching fraction defective is high, directly affects sewing performance, and machine rotational speed can not be too fast while making.
Therefore, in order to solve above technical problem, designed a kind of use in sewing machine thread take-up tension lever, this thread take-up tension lever take-up stroke is large.Utilize this large stroke thread take-up lever structure, can improve the stitching of Sewing machines when making and make take-up attractive in appearance, reduce stitching bad phenomenon, increase work efficiency.
Utility model content
In order to overcome the defect existing in background technology, the utility model solves the technical scheme that its technical problem adopts: a kind of use in sewing machine wire jumper bar, comprise cable-through hole boss, connecting rod, cylinder-shaped link and slide bar, described slide bar is fixedly connected on cylinder-shaped link, the upper end of described cylinder-shaped link is provided with pouring orifice, one end of described connecting rod is fixedly connected on cylinder-shaped link, the other end of described connecting rod is fixedly connected with cable-through hole boss, described cable-through hole boss is provided with cable-through hole one and cable-through hole two, the line of centres of described cable-through hole one and cable-through hole two is parallel with slide bar, described connecting rod is the thickness attenuation gradually to the one end being fixedly connected with cable-through hole boss by the one end being fixedly connected with cylinder-shaped link, the thickness of described cable-through hole boss is greater than the thickness that is fixedly connected with end link with it.
A kind of use in sewing machine thread take-up tension lever that the utility model is related, this thread take-up tension lever take-up stroke is large.Utilize this large stroke thread take-up lever structure, can improve the stitching of Sewing machines when making and make take-up attractive in appearance, reduce stitching bad phenomenon, increase work efficiency.
