Description

The electronic desk-top Sewing machines of double line

The utility model relates to domestic sewing machine.

At present, the desk-top Sewing machines of family expenses has gone on the market and has entered people's family, and hand-rail type, electrodynamic type are arranged, and it is easy to use, be subjected to people's welcome gently, for a short time.When sewing clothes, trousers, often all sew on two lines at the folded-seam place of cloth for strengthening its firmness, people have to sew on a line earlier and sew on another line more like this, make troubles to people.

The purpose of this utility model provides a kind of Sewing machines that can stitch two-wire simultaneously, to increase work efficiency.

Technical solution of the present utility model is the shell at existing desk-top Sewing machines, motor, motor gear, duplicate gear, the vertical shaft bar, pinion, the tooth handwheel, upper shaft lever, guide shaft, shank, top shoe, sliding block, the compress boots, driven gear, following axostylus axostyle, cam, on the basis of compress bar, the utility model is fixed with two mouthfuls of pins side by side separated by a distance at the dress pin position of shank, under the base plate of shell with cam one rotatable contact of lateral edges inner curve on doing, mobile down pinhock is for having with the double hook side by side on the equidistant shank that is fixed in the hook seat with two lancets are corresponding, have one with needle stand on the tooth seat of the rotatable fixing contacted band driving lever of bull stick, the feed dog side by side that has two works separated by a distance to move forward and backward synchronously on the tooth seat.

But crosspointer works asynchronously together during the utility model work, when pin is guided line when planting certain distance into, one carries the line that then plants when pin to last time promptly forms a circle, this moment, pinhock just hooked this circle, plant and mention on the pin behind the position line caused, pinhock then breaks off relations line simultaneously, pin just passes to be inserted under this coil until putting in place, when upwards carrying once more, pin again line is formed second circle, pinhock promptly hooks second circle, and pin is promptly strained the line that first coil makes its coil at this moment and is pulled on the pin, and so for the first time and for the second time the distance between the pin is promptly sewed down.The utility model is when pin, pinhock work, and feed dog also promotes cloth forward synchronously.

But the utility model is also single needle work as required, promptly pulls down a lancet this moment and can carry out the single line sewing.

But the utility model has the advantages that to get final product the also single line sewing of double line sewing, high efficiency, simple in structure, light, little, available alternating current, also available direct current, easy to use, cheap, practical, be easy to promote.

Below in conjunction with accompanying drawing embodiment of the present utility model is described

Fig. 1 organigram of the present utility model.

According to shown in Figure 1, the utility model is at the shell 1 of existing desk-top Sewing machines, motor 2, motor gear 3, duplicate gear 4, vertical shaft bar 5, pinion 6, tooth handwheel 7, upper shaft lever 8, guide shaft 9, shank 10, top shoe 11, sliding block 12, compress boots 14, driven gear 15, following axostylus axostyle 16, cam 17, on the basis of compress bar, particularly the utility model is fixed with two mouthfuls of pins side by side separated by a distance at the dress pin position of shank 10, under the base plate of shell 1 with cam 17 1 rotatable contacts of lateral edges inner curve on doing, mobile down pinhock is for having with the double hook side by side on the equidistant shank that is fixed in the hook seat with two lancets are corresponding, have one with the pinhock seat on the tooth seat of the rotatable fixing contacted band driving lever of bull stick, the feed dog side by side that has two works separated by a distance to move forward and backward synchronously on the tooth seat.There is the hook of one and half inclineds on the top, front of the shank of pinhock, at the back side of shank recessed needle tray is arranged.
