Novel household sewing machine panel tension device

Abstract

The invention discloses a novel household sewing machine panel tension device. The device comprises a connecting rod, six-line threads are uniformly arranged on the surface of the connecting rod, oneend of the connecting rod is in threaded connection with a threaded hole formed in the middle of a rotary button, the other end of the connecting rod is in insertion connection with through holes formed in the middles of two thread clamping plates, and a first spring sleeves the surface of the connecting rod. According to the novel household sewing machine panel tension device, by means of the six-line threads formed in the surface of the connecting rod, the pressure of the first spring can be controlled through the rotary button, and a gap between the two thread clamping plates can be adjusted conveniently. Limiting columns which are in insertion connection with grooves formed in the two sides of the a connecting block are inserted into through holes of a sewing machine shell, assemblingand disassembling of the tension device are facilitated, the tension device can be replaced conveniently, the phenomenon that the tension device is damaged is avoided, and normal work of a sewing machine is affected; by means of a second spring installed at one end of the connecting block, when the tension device is disassembled, the tension device is ejected conveniently.

Description

technical field [0001] The invention relates to a thread clamp, in particular to a novel household sewing machine panel thread clamp. Background technique [0002] A device used on some knitting machines to clamp the yarn on the "feeder" that is about to exit weaving, so that it does not come out of the feeder so that it can be re-entered for work. [0003] The existing thread tensioner is inefficient and inconvenient to operate when adjusting the tension between the two tensioning discs. At the same time, the thread tensioner is not easy to install and disassemble. When the thread tensioner is damaged, it is difficult to replace, which affects the sewing machine usage efficiency. Contents of the invention [0004] The object of the present invention is to provide a novel household sewing machine panel thread tensioner, to solve the problem that the existing thread tensioner proposed in the above background technology is inefficient when adjusting the tension force betwee...
