Description

Technical Field

[0001] The utility model relates to the technical field of sewing machine equipment, and more particularly to a protective cover structure for a sewing machine. Background Art

[0002] Sewing machines are widely used in the production of bags, leather goods, furniture, shoes, clothing, and other products. Existing sewing machines can adjust the needle pitch to adjust the density of the stitches; they can also adjust the needle direction, which allows for forward and reverse stitching. When the sewing machine is not in use, it is often necessary to use a protective cover to cover the thread opening where the sewing mechanism on the sewing machine is sewing to prevent debris from falling into the sewing opening and affecting subsequent sewing work. Existing sewing machine protective covers are of a fixed height and can only be used for a single machine model. The height of the protective cover cannot be adjusted according to actual application conditions. To this end, we propose a new protective cover structure for sewing machines. Utility Model Content

[0005] Optionally, a receiving groove compatible with the sewing thread knotting mechanism on a sewing machine is provided on the inner side of the horizontal plate; and a hollow structure is provided on one side of the receiving groove.

[0006] Optionally, the depth of the accommodating groove is 0.1-0.3 cm.

[0007] Optionally, the vertical plate and the horizontal plate are formed integrally.

[0008] Optionally, the thickness of the vertical board is 0.3cm-0.5cm.

[0009] Optionally, the thickness of the connecting plate is 0.5-1 cm.

[0010] In summary, the utility model has the following beneficial effects: it adopts a structural method of split assembly of the connecting plate and the vertical plate, and uses screws to cooperate with the long holes on the vertical plate so that the vertical plate can adjust the assembly height between the vertical plate and the connecting plate according to actual application conditions, so as to adapt to installation of various models and improve the use efficiency of the protective cover.
