Abstract
The invention relates to a stitch length knob assembly for sewing machines, which is used for adjusting the stitch length of the sewing needle. The stitch length knob assembly comprises a stitch length knob, an adjusting mechanism and a zero setting mechanism, wherein the adjusting mechanism of the invention comprises positioning columns and a stitch length knob seat, and the positioning columns are evenly distributed between the side wall of the outer cover and the counterboring connecting part on the stitch length knob and extend out of the end surface of the outer cover; the stitch length knob seat at least comprises a positioning ring, one inner side surface of which is provided with vertical teeth; the outer side of the end part of each positioning column on the stitch length knob is provided with a bulge which forms an elastic compression fit with the positioning ring, and the end surface of the outer cover of the stitch length knob is arranged corresponding to the end surface of the positioning ring; and the zero setting mechanism comprises a spacing column arranged outside the counterboring connecting part and a bumping post fixedly arranged. Since the direction of the stitch length knob changes under the action of the friction force of the stop pin, as the stitch length becomes larger, the invention has the advantages of fewer changes of torque, low assembly difficulty and lowered cost.

The specific embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
The present invention includes stitch length knob and stitch length knob seat two parts.
Referring to Fig. 1 and Fig. 2, said stitch length knob comprises enclosing cover 8 and hole countersunk connecting portion 6, is evenly equipped with several and stretches out reference column 4 outside enclosing cover 8 end faces between the sidewall of enclosing cover 8 and hole countersunk connecting portion 6, and the end arranged outside of reference column 4 has projection 13; The limited post 7 of hole countersunk connecting portion 6 arranged outside; Evenly be furnished with reinforcement 3 between said reference column 4 and the hole countersunk connecting portion 6.The upper surface of stitch length knob is provided with scale value.
Referring to Fig. 3 and Fig. 4, the lid shape that said stitch length knob seat 1 is porose for the middle part is provided with, its outer ring is the centring ring 5 that a medial surface is provided with vertical tooth, and bumping post 10 is arranged on the inside bottom of stitch length knob seat 1, and the lateral surface on the centring ring 5 of stitch length knob seat 1 is provided with mark.
Referring to Fig. 5, for needs are installed, the casing installation portion 2 of Sewing machines is provided with embedded groove 11, and the stitch length knob seat embeds and be fixing.
Stitch length knob seat and casing installation portion 2 be combined with a lot of modes, bonding or screw is connected in casing installation portion 2 and also can.Be not limited to aforesaid way.
Referring to Fig. 6, adjust screw rod and be arranged in the casing installation portion 2, adjust screw rod and fixedly connected with the hole countersunk connecting portion.The corresponding setting of end face of end face and the centring ring 5 of enclosing cover 8 is provided with spring 9 between the bottom of enclosing cover 8 and the stitch length knob seat 1 in this moment stitch length knob, and the end bosses 13 of reference column 4 and centring ring 5 sides formation elastic pressure are press-fitted structure.
In this structure, reference column 4 on the stitch length knob on the enclosing cover 8 and the centring ring of stitch length knob seat 5 form guiding mechanism.The stitch length knob rotation, the end bosses 13 of reference column 4 cooperates with the vertical tooth spiral commentaries on classics of centring ring 5 medial surfaces and locatees, and stitch length knob drives adjusts screw action.
In this structure, limited post 7 and the bumping post on the stitch length knob seat 1 10 on the stitch length knob constitute zero detent mechanism, and when stitch length knob rotated to zero-bit, limited post 7 was blocked by bumping post 10.
