Description

The dial protecting cover structural improvement of sewing machine

Technical field:

The utility model relates to the sewing machine technical field, refers in particular to a kind of dial protecting cover structural improvement of sewing machine.

Background technology:

Sewing machine is one of main mechanical in the knitting industry, and the performance of machine is directly connected to the suture quality of fabric.In the prior art, generally there is a dial protecting cover mid-game upper end of sewing machine, protects mid-game with this, scratch mid-game surface paint when avoiding place tool or article.Current, dial protecting cover and mid-game are by the combination of securing member interlockings such as screw, dismounting inconvenience, and manufacturing technique complexity, cost height.

Summary of the invention:

The purpose of this utility model is to overcome the defective of prior art, provides a kind of simple in structure, the dial protecting cover structural improvement of the sewing machine of easy accessibility.

For achieving the above object, the middle part convexes with a flange down in the lid of the utility model, and the mesopore that coils among the shape of flange, size and the sewing machine is complementary.

Flange is cylindric, and itself and lid are structure as a whole.

The utility model is directly cooperated with the mesopore of mid-game by the flange of lid and is located by connecting, and assembles simply, convenient, fast, need not screw lock, and cost of manufacture is low.

Description of drawings:

Accompanying drawing 1 is a vertical view of the present utility model;

Accompanying drawing 2 is a side view cutaway drawing of the present utility model;

Accompanying drawing 3 uses schematic diagram for the utility model assembling.

The specific embodiment:

See that the utility model includes lid 1 shown in the accompanying drawing 1,2, the middle part convexes with a flange 11 down in the lid 1, and the mesopore 21 of dish 2 is complementary among the shape of flange 11, size and the sewing machine.Flange 11 is cylindric, and itself and lid 1 are structure as a whole.

See that shown in the accompanying drawing 3, lid 1 is combined in the upper end of mid-game 2 during use, the surface of mid-game 2 was both played a protective role, beautify the overall appearance of sewing machine again.The flange 11 of lid 1 inserts in the mesopore 21 of mid-game 2, directly utilizes mesopore 21 location of mid-game 2, realizes being located by connecting, and need not screw lock, easy accessibility.
