Novel machine needle for sewing machine

Abstract

The invention relates to a novel machine needle for a sewing machine. The needle comprises a connection column, one end of which is fixedly welded with a transfer sleeve. A thread cavity is dug out ofthe interior of the transfer sleeve. One end in the interior of the thread cavity is fixedly equipped with a first buffer pad. One side of the first buffer pad is horizontally and fixedly connected with a limit spring column. One end, away from the first buffer pad, of the limit spring column is fixedly connected with a second buffer pad. Two ends of a threaded rod are symmetrically equipped witha machine needle body such that the machine needle for the sewing machine can be used at both ends. Accordingly, service lifetime of the machine needle for the sewing machine is prolonged. By arranging the limit spring column, the machine needle body is limited in order to prevent the machine needle body from contracting into the interior of the thread cavity. By arranging an elliptical groove, the elliptical groove exerts guide effect in order to greatly save threading time. By arranging a fixing bolt, the thread rod can be secondarily positioned in order to prevent the thread rod from shaking. By arranging a marking line, an observation window and a scale line, the position of the machine needle body can be precisely adjusted.

[0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material to interweave or sew one or more layers of sewing materials. The sewing machine can sew cotton, hemp, silk, wool , artificial fiber and other fabrics and leather, plastic, paper and other products, the stitches are neat and beautiful, smooth and firm, the sewing speed is fast, and it is easy to use. Different sewing effects can be achieved by selecting different specifications of machine needles. The existing sewing machine When installing the machine needle, it is usually directly inserted into the installation groove, and then fastened with a positioning piece. The sewing thread is passed through the lead hole of the machine needle, and different needles are selected according to the thickness of the thread, but the needle used for thin thread The lead hole of the machine is too small, which makes threading quite difficult. At the same time, it is inconvenient to adjust the existing machine needle after it is installed on the sewing machine. If you want to replace or adjust it, you must remove the needle chuck of the sewing machine, and the steps are cumbersome.
