Abstract

The utility model relates to a shuttle carrier for sewing machines, which is composed of a shuttle carrier body, a shuttle carrier ring and two presser feet, wherein, the shuttle carrier is an integral casting component; the shuttle carrier ring is positioned on a ring step at the upper part of the shuttle carrier body and are clamped by the two presser feet; the lower part of the shuttle carrier body is provided with a tubular long shaft which is used for connecting a peculiar drive mechanism of the complete machine of a sewing machine. The utility model is connected with the drive mechanism of the complete machine by the long handle of the shuttle carrier body; the utility model is movable in the sewing machine so that the utility model can simultaneously move with a sewing needle at the horizontal direction. Thus, the sewing machine can process and produce many more patterns.

Description

Rotating shuttle for sewing machine

The utility model relates to a kind of shuttle race of multi-purpose sewing machine.

Multi-purpose sewing machine in the market generally can both be processed the multiple decorative pattern of sewing out, and the style of its decorative pattern changes the scope of the horizontal reciprocating movement that depends on sewing needle: range of movement more greatly, style is also just many more.The shuttle race of older generation's multi-purpose sewing machine is that horizontal positioned or vertical placement are all fixed, and because of the peg or spindle that is positioned at shuttle race pins down, the horizontal reciprocating movement of sewing needle is limited in the small range, so the decorative pattern that can process is also less.So further improving imagination is to make shuttle race and the reciprocating motion of sewing needle level of synchronization, just can increase the style of decorative pattern greatly.

The purpose of this utility model just is to provide a kind of shuttle race that cooperates Sewing machines of new generation, under driving at the special transmission mechanism of complete machine with sewing needle horizontal reciprocating movement synchronously.

Scheme of the present utility model is: shuttle race is made up of shuttle race cap, shuttle race circle and two presser feets, shuttle race cap is a single-casting, the shuttle race circle places on the circle step on shuttle race cap top and by two presser feet fastenings, the bottom of shuttle race cap is a tubulose long handle, in order to be connected with the distinctive transmission mechanism of Sewing machines complete machine.

The utility model no longer maintains static in Sewing machines, and can be synchronized with the movement in the horizontal direction with sewing needle because of being connected with the complete machine transmission mechanism by the long handle of shuttle race cap, more spends more the decorative pattern of sample so Sewing machines processing is sewed out.

Description of drawings.

Fig. 1 is a front view of the present utility model.

Fig. 2 is the left view of Fig. 1.

Fig. 3 is an exploded perspective view of the present utility model.

Fig. 4 is the utility model is connected embodiment with the Sewing machines complete machine a perspective view (part).

Embodiment is further described the utility model below in conjunction with accompanying drawing.

Shown in Fig. 1～3, shuttle race is by shuttle race cap (1), shuttle race circle (2) and two presser feets (3) are formed, shuttle race cap (1) is a single-casting, be divided into two parts up and down, hollow, one circle step (7) is arranged at top, in order to bear shuttle race circle (2), it is the ear shape that respectively there is an outer lug on its bilateral symmetry ground, presser feet (3) is by screw (6), spring (5) is fixed in this place, and can rotate among a small circle around the screw central shaft, and the last plane bilateral symmetry of shuttle race circle (2) respectively has a kick, after shuttle race circle (2) is put into shuttle race cap (1), rotate presser feet (3) make its end push down shuttle race circle (2) even kick shuttle race circle (2) fixing; The bottom of shuttle race cap (1) is the long handle of a tubulose, it can be connected with the distinctive transmission mechanism of Sewing machines, wherein (4) are tank filler sleeve, as shown in Figure 4, the peg or spindle bar (12) that end is connected with peg or spindle passes the shuttle race handle, and can freely rotate relative to the shuttle race handle, the shuttle race handle is connected with connecting rod (11) by anchor ear (13), and connecting rod (11) is the part of the peculiar transmission mechanism of Sewing machines self, can with the synchronously reciprocal translation of level of sewing needle, so also drive the back and forth translation synchronously of whole shuttle race and sewing needle.

Claims

1, a kind of Sewing machines shuttle race, form by shuttle race cap (1), shuttle race circle (2) and two presser feets (3), shuttle race cap (1) is a single-casting, shuttle race circle (2) places the circle step (7) on shuttle race cap (1) top to go up and by two presser feets (3) fastening, the bottom that it is characterized in that shuttle race cap (1) is a tubulose long handle, in order to be connected with the distinctive transmission mechanism of Sewing machines complete machine.

2, Sewing machines shuttle race as claimed in claim 1 is characterized in that the tubulose long handle side of described shuttle race cap bottom has tank filler sleeve (4).
