Sewing thread spool

Abstract

The invention discloses a sewing thread spool. The sewing thread spool comprises a cylindrical spool body, baffle plates and a magnetic inner ring, wherein the baffle plates which are integrally formed with the spool body are arranged at the two ends of the spool body, openings in the middle parts of the two baffle plates are communicated with an inner cavity of the spool body, threading holes and grooves are formed in the baffle plates by being close to the edges, blades are arranged in the grooves, and according to the technical key points, thread inlets communicated with the threading holes are formed in the edges of the baffle plates, a partition plate is arranged in the inner cavity of the spool body, the magnetic inner ring is arranged at the opening in the middle of one baffle plate, and a space defined by the inner wall of the spool body which is close to one side of the magnetic inner ring and the partition plate serves as a needle keeping chamber. According to the sewing thread spool disclosed by the invention, a sewing thread can fast and conveniently slide into the threading holes, the spool can rotate and pay off normally on a sewing machine, and the situation that the blades are exposed to cause scratches is avoided, so that the use is safe.

Description

technical field [0001] The invention belongs to a bobbin for winding sewing thread, in particular to a sewing thread bobbin. Background technique [0002] For cutting and sewing in daily life, the bobbin is an indispensable tool, but the existing bobbin only has the basic function of thread winding, and it is necessary for the necessary thread finding, threading, thread breaking, picking up needles, etc. in the cutting and sewing process. Needs such as depositing needles cannot provide necessary help. The patent document with the notification number CN202848774U discloses a convenient spool, which includes an upper baffle and a lower baffle at both ends of the spool. The edge of the upper baffle is provided with a thread hole for threading and a blade for cutting the thread. The spool is a cylindrical tube. , one end of which is closed, and a through hole is provided at the center of the upper baffle corresponding to the opening of the bobbin. To pick up needles, this bobb...

Problems solved by technology

[0002] For cutting and sewing in daily life, the bobbin is an indispensable tool, but the existing bobbin only has the basic function of thread winding, and it is necessary for the necessary thread finding, threading, thread breaking, picking up needles, etc. in the cutting and sewing process. Unable to provide necessary help for needle deposits and other needs

The patent document with the notification number CN202848774U discloses a convenient spool, which includes an upper baffle and a lower baffle at both ends of the spool. The edge of the upper baffle is provided with a thread hole for threading and a blade for cutting the thread. The spool is a cylindrical tube. , one end of which is closed, and a through hole is provided at the center of the upper baffle corresponding to the opening of the bobbin. To pick up needles, this bobbin achieves the functions of thread finding, threading, thread breaking, picking up and storing needles. More cumbersome to operate

In addition, in today's society, sewing machines are mostly used to sew clothes, and the sewing machines are mostly made of metal materials, and the upper surface is provided with a fixed rod for fixing the bobbin. When the spool is set on the fixed rod of the sewing machine, the spool will be in close contact with the fixed rod due to the magnetic force of the ring magnet, so that the spool cannot rotate with the movement of the sewing machine, so the spool cannot be unwound, and the sewing work of the sewing machine cannot be carried out. , and it is easy to break the wire
