Description

Technical Field

[0001] The utility model belongs to the technical field of sewing machine accessories, in particular to a sewing machine thread rack structure. Background Art

[0002] The thread stand of a sewing machine is used to hold the thread and guide the thread to the clamp or needle of the sewing machine. It is one of the key components to ensure the smooth operation of the sewing machine. It supports the thread stand and pulls the thread upward, guiding the top layer of thread to the sewing machine. The thread stand structure is equipped with thread threading holes, which are used to thread the thread. However, the design structure of existing sewing machine thread stands is relatively fixed, and the position of the thread support plate and tray is difficult to adjust, making it difficult to meet different usage requirements.

[0003] Publication number CN220724512U is a Chinese utility model patent, which discloses a sewing machine thread stand. By turning the adjustment knob and driving the screw to rotate three times, the use position of the thread guide sleeve can be adjusted. By turning the control wheel and driving the screw to rotate once, the limit block slides out of the limit slot to cancel the fixed restriction of the adjustment sleeve, and the tray on the adjustment sleeve can be moved. Reverse rotation of the control ring plate can drive the limit block to reset and insert it into the corresponding limit slot to fix the position of the tray. However, this device still has some other problems. For example, the device cannot fix the tower wire spool well. It is easy to shake when the tower wire is rotating or drawing out, causing the tower wire to be tangled and broken, affecting the normal drawing out and thus affecting the sewing work efficiency.
