The Middle pressure foot mechanism of the sewing machine has simple structure and low production and maintenance costs.
Description
Technical field
The utility model relates to Sewing machines, specifically a kind of middle presser foot device of Sewing machines.
Background technology
The tradition Sewing machines is easy to eedle when carrying eedle on making material and drives material and carry so easy wire jumper on together.For address this problem increased on traditional Sewing machines a kind of in presser foot device can play anti-wire jumper function.But presser foot device complexity, manufacturing and maintenance cost height are unfavorable for Enterprises'Competitiveness in traditional Sewing machines.
The utility model content
At the defective that exists in the prior art, the purpose of this utility model is to provide a kind of middle presser foot device of Sewing machines, and is simple in structure, and manufacturing and maintenance cost are low.
For reaching above purpose, the technical scheme that the utility model is taked is:
A kind of middle presser foot device of Sewing machines, it is characterized in that: shank 6 one ends are provided with eedle 4, are set with stage clip 3 and pressure head 2 on the eedle 4 successively, and fixed cover 1 is enclosed within on the shank 6 and with stage clip 3 and is placed in its inside, pressure head 2 one ends are stuck in the fixed cover 1, and the other end exposes fixed cover 1.
On the basis of technique scheme, what also be provided with fixedly eedle 4 and fixed cover 1 on the shank 6 tightens screw 5.
On the basis of technique scheme, the syringe needle of eedle 4 is exposed to the outside after passing stage clip 3, pressure head 2 and fixed cover 1.
On the basis of technique scheme, the end that pressure head 2 contacts with stage clip 3 is provided with and increases the boss that contact area is used, and the other end is provided with V-type unwrapping wire groove 7.
The middle presser foot device of Sewing machines described in the utility model is simple in structure, and manufacturing and maintenance cost are low.
Description of drawings
The utility model has following accompanying drawing:
The blast structural representation of the middle presser foot device of Fig. 1 Sewing machines
The structural representation of the middle presser foot device of Fig. 2 Sewing machines
Fig. 3 pressuring head part front view
Fig. 4 pressuring head part side view
Reference numeral:
1 is fixed cover, and 2 is pressure head, and 3 is stage clip, and 4 is eedle, and 5 for tightening screw, and 6 is shank, and 7 is V-type unwrapping wire groove.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is the blast structural representation of the middle presser foot device of Sewing machines described in the utility model, Fig. 2 is the structural representation of the middle presser foot device of the Sewing machines after assembling, shank 6 one ends are provided with eedle 4, be set with stage clip 3 and pressure head 2 on the eedle 4 successively, fixed cover 1 is enclosed within on the shank 6 and with stage clip 3 and is placed in its inside, pressure head 2 one ends are stuck in the fixed cover 1, and the other end exposes fixed cover 1.
On the basis of technique scheme, what also be provided with fixedly eedle 4 and fixed cover 1 on the shank 6 tightens screw 5.
On the basis of technique scheme, the syringe needle of eedle 4 is exposed to the outside after passing stage clip 3, pressure head 2 and fixed cover 1.
On the basis of technique scheme, as shown in Figure 3, Figure 4, the end that pressure head 2 contacts with stage clip 3 is provided with and increases the boss that contact area is used, and the other end is provided with V-type unwrapping wire groove 7.
The operation principle of the middle presser foot device of Sewing machines described in the utility model is as follows: drive fixed cover when shank is descending, pressure head, eedle be descending together, be pressed in when making thing and pressing when pressure head, eedle has entered the thing work of making, this moment, stage clip was energy storage, when the eedle back of finishing the work drives when up at shank, this moment the stage clip release pressure, pressure head is pressed on the material, after eedle rises to certain altitude and hook line and finishes, pressure head just leaves material, can well play anti-wire jumper effect like this.As shown in Figure 3, Figure 4, boss has promptly played the effect that increases pressure head 2 and stage clip 3 contacts area, also has concurrently pressure head 2 one ends are stuck in the effect of avoiding it to drop out in the fixed cover 1.
