Description

Technical Field

[0001] The utility model relates to the technical field of sewing machines, in particular to a sewing machine casing component which is easy to disassemble. Background Art

[0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material, so that one or more layers of sewing materials are interwoven or sewn together. Sewing machines can sew fabrics such as cotton, linen, silk, wool, and artificial fibers, as well as products such as leather, plastic, and paper. The stitches are neat, beautiful, flat, and firm, and the sewing speed is fast and easy to use. Art forms such as hand-push embroidery and computer embroidery have been derived from them. According to the purpose of the sewing machine, it can be divided into household sewing machines, industrial sewing machines, and sewing machines for service industries between the two; according to the driving mode, it can be divided into hand-cranked, foot-operated, and electric sewing machines; according to the stitches, it can be divided into imitation hand-sewn stitches, lock stitches, single-thread chain stitches, double-thread or multi-thread chain stitches, single-thread or multi-thread hemming chain stitches, and multi-thread covered chain stitch sewing machines.

[0003] After searching, a utility model patent with Chinese patent publication number CN210621145U discloses a sewing machine casing, which belongs to the technical field of sewing machines, including a shell and a base, a handle is fixed on the top of the shell, a power switch is installed above the outer surface of the shell, and heat dissipation holes and a first slide groove are respectively opened below the outer surface of the shell; a first slide groove, a slider, a connecting rod, and a dustproof plate are provided. When the sewing machine is not needed, the user pulls the dustproof plate along the direction of the heat dissipation hole, and the movement of the dustproof plate causes the connecting rod to move, and at the same time drives the slider to slide in the first slide groove. When the dustproof plate moves to completely block the heat dissipation hole, the user no longer pulls the dustproof plate to prevent a large amount of dust from entering the interior through the heat dissipation hole when the sewing machine is idle, thereby reducing the amount of dust accumulated inside the sewing machine, and at the same time improving the service life of the internal components of the sewing machine, and avoiding excessive dust accumulation affecting the working efficiency of the internal components.
