Abstract
The invention relates to a thread tensioning device with a scale for a sewing machine. The thread tensioning device comprises a screw rod and a matched nut; two compacting sheets parallel to the nut are sleeved on the screw rod; and a spring is also sleeved between the two compacting sheets and the nut. The thread tensioning device is characterized in that the scale perpendicular to the axial line direction of the screw rod is arranged on a rod body of the screw rod. The regulating scale is additionally arranged on the thread tensioning device for the sewing machine, which is provided by the invention, so that the same regulating variable can be repeatedly acquired quite conveniently in a manner corresponding to the scale for a product with the same sewing requirement; and the same tension of an upper thread for the sewing machine is obtained, so as to improve regulation efficiency and the quality and the stability of the sewed pattern of the product.
Description
Technical field
The present invention relates to a kind of thread tensioner for sewing machine, relate in particular to a kind of adjusting sewing machine surface thread tension force, and have the turnbuckle of scale.
Background technology
Usually, Sewing machines cooperates through the eedle of needle plate top and the rotating shuttle of needle plate below, and upper thread and bottom line are combined, and on lining, forms the seam mark.During Sewing machines work, need to regulate the tension force of upper thread and bottom line, to guarantee the smooth, attractive in appearance of seam mark.At present, the tension force of sewing machine surface thread mainly is through realizing regulating with the turnbuckle of nut and spring cooperating.But; Owing to be not with scale, the bad control of regulating quantity, poor reproducibility on the common turnbuckle; So that each time before the sewing all repeatedly the degree of tightness adjusting knob seek and obtain optimum tension, it is stable with the sewing that requires product equally to be an impediment to the further raising of sewing efficiency.
Summary of the invention
The present invention has overcome the deficiency of prior art, provides a kind of simple in structure, sets up the adjusting scale, and the regulating quantity favorable reproducibility is regulated efficient and improved, the thread tensioner for sewing machine that sewing stability is good.
For achieving the above object; The technical scheme that the present invention adopts is: a kind of thread tensioner for sewing machine with scale; Comprise screw rod and supporting nut; Be with two clamping pieces that are parallel to nut on the said screw rod, also be arranged with spring between two clamping pieces and nut, it is characterized in that: said screw rod shaft is provided with the scale perpendicular to the screw axis direction.
In preferred embodiment of the present invention, comprise that further the side of said nut is provided with the graduation mark that is parallel to the nut axis.
In preferred embodiment of the present invention, further comprise said nut in the position on the screw rod shaft between spring and screw rod scale.
In preferred embodiment of the present invention, comprise further on the said screw rod that along the same direction of screw axis, the distance between adjacent two scales is corresponding successively with the pitch between adjacent two screw threads.
In preferred embodiment of the present invention, comprise that further said screw rod shaft is provided with the graticule corresponding to said nut scale.
The invention solves the defective that exists in the background technology; Thread tensioner for sewing machine of the present invention is set up the adjusting scale; The feasible product that requires for same sewing; Can repeat very easily to obtain same regulating quantity by corresponding scale, obtain same sewing machine surface thread tension force, thereby improve the quality and the stability of regulating efficient and product sewing style.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is the structural representations of the preferred embodiments of the present invention when spring is in the nature elongation state;
Fig. 2 is the structural representations of the preferred embodiments of the present invention when spring is in compressive state;
Among the figure: 2, screw rod, 21, the screw rod scale, 22, screw flight, 23, the screw rod graticule, 4, nut, 41, the nut scale, 42, nut end face, 6, two clamping pieces, 61, decide clamping piece, 62, moving clamping piece, 8, spring.
The specific embodiment
Combine accompanying drawing and embodiment that the present invention is done further detailed explanation now, these accompanying drawings are the sketch map of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
As shown in Figure 1; A kind of thread tensioner for sewing machine of the present invention with scale; Comprise screw rod 2 and supporting nut 4; Be with two clamping piece 6, two clamping pieces 6 and 4 on nuts that are parallel to nut 4 on the said screw rod 2 and also be arranged with spring 8, said screw rod 2 shafts are provided with the scale 21 perpendicular to screw rod 2 axis directions.Said nut 4 through with screw rod 2 shafts on the supporting internal thread of external screw thread 22, be screwed in the shaft periphery.In described two clamping pieces 6, one of which is fixed in screw rod 2 shafts for to decide clamping piece 61; Another is independent of screw rod 2 and links to each other with spring 8 for moving clamping piece 62.Said spring 8 is located between moving clamping piece 62 and the nut 4.Said nut 4 in the position on screw rod 2 shafts between spring 8 and screw rod scale 21.Screw thread 22 uniform pitchs on the said screw rod 2, and along the same direction of screw rod 2 axis, the distance that adjacent two screw rods scale is 21 equates with the pitch of 22 on any adjacent two screw threads.The side of said nut 4 is provided with the graduation mark 41 that is parallel to nut 4 axis, and said nut graduation mark 41 evenly distributes along nut 4 side circumference.Said screw rod 2 shafts are provided with the graticule 23 corresponding to said nut scale 41.
During use, turnbuckle of the present invention is installed on the Sewing machines fuselage by conventional method, nut 4 outwardly.Sewing machine surface thread is walked around the screw portion between two clamping pieces, and turn nut 4 drives the moving clamping piece 62 of spring 8 compressions, makes clamping piece 62 to deciding clamping piece 61 near, the upper thread that clamping mediates.Therefore,, can regulate the distance of 6 of two clamping pieces through turn nut 4, thus the adjusting range line tension.When to clamping piece 6 direction turn nuts 4, move corresponding to screw rod scale 21 in nut 4 cross sections, when one of nut 4 during from the just corresponding screw rod scale 21 of clamping piece 6 end face far away 42, is an adjusting position that can accurately reappear.Again because nut 4 rotates a circle; Along the axis pitch of advancing; Therefore the scale 41 of nut is replenishing and precision as screw rod scale 21; When between the above-mentioned nut end face 42 corresponding two adjacent screw rod scales 21, the angle orientation that can turn over by nut 4, promptly on the nut 4 corresponding to the scale position of screw rod graticule 23.Being arranged so that of scale, more accurately stable chain of command line tension to the high product of sewing quality requirement.
Above foundation desirable embodiment of the present invention is enlightenment, and through above-mentioned description, the related personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the specification, must confirm technical scope according to the claim scope.
