Description

Dust-proof cover of sewing machine

The utility model relates to a kind of dust cap of Sewing machines.

Early stage domestic sewing machine is made up of frame and rack-mounted head of sewing machine, when Sewing machines does not use, for preventing that dust in air from descending slowly and lightly or, on head, all be covered with one usually and make the dust cover that forms by cloth or Polypropylence Sheet attached on the head.In recent years, along with domestic sewing machine develops to miniaturization, portable direction,, generally also all be that Sewing machines is equipped with a dust cap of being made by rigid plastics for making things convenient for using and collecting of Sewing machines, when Sewing machines does not use, prevent dust being used in the outside that just this dust cap is located at Sewing machines.

From the action and function of above-mentioned Sewing machines dust cover or dust cap, we can find: no matter be early stage dust cover or present dust cap, they all only possess single dust reduction capability, and do not have other function.But, development trend from present Sewing machines volume and style, because the miniaturization of Sewing machines forward, portable direction develop, this Sewing machines is compared with early stage domestic sewing machine, and its work top certainly will be narrower, makes object when people use it, during especially than big article, object is difficult for being evened up whole on the sewing machine table face, therefore, can have a strong impact on user's easy to operate and sewing quality; And, even this Sewing machines is placed use on the table,, therefore, still can not fundamentally solve above deficiency because the work top of Sewing machines exceeds desktop.

The purpose of this utility model is: a kind of Dust-proof cover of sewing machine is provided, and this dust cap not only has the dustproof function, but also has the effect of extending the work top that enlarges Sewing machines, thereby is that people provide convenience when using the stitching sewing machine object.

For realizing the purpose of this utility model, a kind of Dust-proof cover of sewing machine, the top of lid offers a perforation that can supply the Sewing machines carrying handle to pass, described dust cap is made up of two corresponding mutually first lid and second lids, perforation is opened in the top of first lid, offer the mating groove of an indent in a side of second lid, the shape of mating groove is corresponding with Sewing machines work platform, also is provided with the inferior lid that shape is corresponding with mating groove and can be dismantled by activity at the mating groove place.

The utility model has the advantages that: by ingenious design the Sewing machines dustproof cover structure, not only kept its original dust reduction capability, but also increased its extension and enlarged the function of sewing machine table face, promptly when this dust cap and Sewing machines are used, convenient making than big article, and help guaranteeing the sewing quality of object, simultaneously, this lid is compared with traditional dust cap can not be increased volume or occupy bigger space.

Below in conjunction with accompanying drawing the utility model is described in further detail.
