Embodiment 1

[0030] Such as figure 1 As shown, this kind of sewing machine waste storage device is composed of two parts: storage bag 1 and base 2.

[0031] Wherein, the base 2 is cylindrical, the inner side wall of the upper end of the base 2 is inclined outward to form a tapered guide surface 2a, and the guide surface 2a extends to the upper end surface of the base 2 to prevent waste materials from entering the base 2 Play a guiding role, so that the waste material enters the base 2 more smoothly and stably.

[0032] The outer side of the upper end of the base 2 is provided with a positioning structure for clamping the edge of the sewing machine table. In this embodiment, the positioning structure includes protrusions 2b on the outer side wall of the upper end of the base 2, wherein there are two protrusions 2b and they are arranged up and down. A clamping opening 2c is formed between the two protrusions 2b. During installation, the edge of the sewing machine table is inserted into the c...

Embodiment 2

[0037] The structure and principle of the second embodiment are basically the same as those of the first embodiment. The difference is that the connecting structure includes a male snap fixedly connected to the outer side wall of the lower end of the base 2 and a female fixedly connected to the inner side wall of the connecting portion 1b. Snaps, male and female snaps are connected together. The connecting portion 1b is fastened and connected together by a male snap button and a female snap button, and has the advantages of simple structure and firm connection, thereby further improving the reliability of the connection between the storage bag 1 and the base 2.

Abstract

The invention provides a waste storage device of a sewing machine. The device belongs to the technical field of machinery. The invention solves the problem that a storage bag of an existing sewing machine waste storage device is not connected stably. The waste storage device of the sewing machine comprises a storage bag and a cylindrical base, wherein a positioning structure used to clamp machine table edges of the sewing machine is disposed on the outer side of the upper end of the base; the inner side wall of the upper end of the base inclines outwards to form a conical guide face which extends to the end face of the upper end of the base; the storage bag comprises a storage part and a cylindrical connecting part; the connecting part sleeves the lower end of the base; a connecting structure which forms a detachable connection of the connecting part and the lower end of the base is disposed between the connecting part and the lower end of the base; and a coaxially disposed clamping spring is clamped on the outer side wall of the connecting part. The waste storage device of the sewing machine has the advantage of firm connection of the storage bag.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a sewing machine, in particular to a sewing machine waste storage device. Background technique [0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material to interweave or sew one or more layers of sewing material. [0003] The existing sewing machine waste storage device, such as a sewing machine waste storage device disclosed in China Patent Library [Application No.: 201310741826.9; Authorized Notice No.: CN103696175A], has a base, and the base is provided with an inlet and an outlet that communicate with each other. A protrusion for installing the storage bag is provided on the edge of the bottom, a clamp is provided on one side of the top, a fastening pin is provided on the clamp, and the bottom surface of the inlet is inclined. [0004] When the above-mentioned sewing machine waste storage device is install...
