CN201056621Y - Structure for reducing tension force of facial suture - Google Patents

Abstract

The utility model belongs to the technical field of sewing machines and designs a structure capable of reducing the tension of top threads. The utility model comprises a thread-buffering hook support column (1), a thread-passing bearing mount column (2), a thread-passing bearing (3), and an anti-falling thread hook (4). The utility model is characterized in that the embodiment modifies the prior thread-buffering hook (5), designs one end of the thread-passing bearing mount column (2) to be a threaded column and the other end to be a bearing seat, installs the thread-passing bearing (3) onto the bearing seat of the thread-passing bearing mount column (2) and simultaneously arranges the anti-falling thread hook (4) on the top of the thread-passing bearing mount column (2), and then fixes them with the thread-buffering hook support column (1) by threaded connection. The prior surface-contact sliding friction between the thread-buffering hook (5) and suture thread is replaced by the point-contact rolling friction, so as to reduce the tension of top threads.

Description

A kind of structure that reduces upper thread tension force

Technical field:

The utility model belongs to sewing machine technique, particularly a kind of structure that reduces upper thread tension force.

Background technology:

The upper thread of flat seam machine generally need pass through each associated mechanisms, and because the mechanism of upper thread process is too much, often causes the increase of upper thread tension force easily.When upper thread colludes through slow line, being the face contact because upper thread colludes with line particularly, is sliding friction, the easier increase that causes tension force.When the overtension of flat seam machine, make easily cloth shrink, wrinkling, cause the not attractive in appearance of stitching, and break easily when making.

The utility model content:

The purpose of this utility model is a kind of structure that can reduce upper thread tension force of design.

The utility model comprises that slow line colludes that pillar 1, passing spool hold erection column 2, passing spool holds 3, anti-off-line colludes 4, slow line before it is characterized in that present embodiment improved colludes 5 and changes into and colluded by slow line that pillar 1, passing spool hold erection column 2, passing spool holds 3, the 4 slow line apparatus that assemble are colluded in anti-off-line, slow line colludes 5 and contacts sliding friction with the face of suture before replacing with the some touch scrolling friction of bearing and suture, thus the tension force of minimizing upper thread.

The utility model has designed slow line and has colluded that pillar 1, passing spool hold erection column 2, passing spool holds 3, anti-off-line colludes 4, slow line before the present embodiment improvement is colluded 5 be divided into two parts, the one, slow line colludes pillar 1, the 2nd, passing spool is held 3 be installed in passing spool and hold on the erection column 2, at the top that passing spool holds erection column 2 anti-off-line has been installed simultaneously and has colluded 4.By being threaded these two parts are linked together again.

Description of drawings:

Fig. 1 is the part installation diagram of the utility model after implementing, Fig. 2 implements preceding slow line for the utility model and colludes 5 part drawings, Fig. 3 colludes the pillar part drawing for the slow line of the utility model, and Fig. 4 holds the erection column part drawing for the utility model passing spool, and Fig. 5 colludes part drawing for the anti-off-line of the utility model.

The specific embodiment:

With reference to Fig. 1, Fig. 2, slow line before the present embodiment improvement on Fig. 1 is colluded 5 be divided into two parts, by improvement shown in Figure 2, the part after the improvement comprises that slow line colludes that pillar 1, passing spool hold erection column 2, passing spool holds 3, and anti-off-line colludes 4, an end that passing spool is held erection column 2 is designed to a double-screw bolt, the other end is designed to bearing block, passing spool is held 3 be installed on bearing block one end that passing spool holds erection column 2, at the top that passing spool holds erection column 2 anti-off-line is installed simultaneously and colludes 4.By being threaded they and slow line being colluded pillar 1 again is connected.Whole erection was on flat seam machine after connection was finished.

Claims (2)

1. a structure that reduces upper thread tension force comprises that slow line colludes that pillar (1), passing spool hold erection column (2), passing spool holds (3), and (4) are colluded in anti-off-line, it is characterized in that slow line is colluded (5) is designed to two sections;

2. a kind of structure that reduces upper thread tension force according to claim 1 is characterized in that colluding (5) one ends at slow line has installed passing spool and hold (3), and adds that anti-off-line colludes the disengaging that (4) prevent suture.
