Abstract
The utility model relates to a straight speed adjuster of industrial sewing machine, which comprises a notch support, a drawing rod, a screw spring and a magnetic-electric sensor, arranged on the driver frame of sewing machine, wherein the drawing rod is long, which upper is provided with a protruded circumference above which a straight rod is extended, the straight rod is sheathed with a magnetic steel, the lower of the protruded circumference is arranged with a long rod portion of the drawing rod, while the lower end of the drawing rod is arranged with a wire drawing post, the long rod portion is serially connected with a screw spring to be supported in the notch of the notch support, and the straight rod at upper end can be inserted into the coil of the above magnetic-electric sensor and the induction area of magnetic sensitive element. The utility model has the advantages of non contact, long service life, and high practicality, which can be used for straight speed adjustment as electric power assist vehicle.
Description
Technical field
The utility model relates to Sewing machines, is a kind of industrial sewing machine straight line speed adjusting gear.
Background technology
Existing industrial sewing machine is generally all with the ac motor source that is used as power, industrial sewing machine does not in use have speed and adjusts function, have only commentaries on classics, stop two states, and ac motor adopts the friction disk type structure more, very easily damage, in addition, motor also wastes in energising when no duty, noise is very big, and mechanical property is not hard yet during low speed.
Summary of the invention
When the purpose of this utility model provides a kind of industrial sewing machine and is used as power the source with dc motor, a kind of orthoscopic speed adjusting gear of design, it needs user can realize the purpose of speed governing with the pin operation.
The utility model of realizing above-mentioned purpose is to have slot type support, a stretching bar, a helical spring and a magnetoelectric induction device that is located on the Sewing machines driving mechanism frame; The stretching bar is a stock body, has a circle convex circumference at an upper portion thereof, and a straight-bar is extended in the convex circumference top, and the lower end of straight-bar is provided with a cable traction post; Be erected in the notch of slot type support behind tandem arrangement one helical spring on the stock body, and its upper end straight-bar can be stretched insert the coil of the magnetoelectric induction device that is arranged in its top and the induction region that magnetosensitive is answered element.
The utility model as mentioned above, when foot pedals spurs the stretching bar to bottom offset by pull rope, the upper end straight-bar of stretching bar breaks away from the coil and the magneto sensor induction region of magnetic inductor, the electric weight of coil neutralization magneto sensor promptly changes, rotating speed by control circuit control motor reaches the highest, on the other hand, because the stretching bar is when bottom offset, the convex circumference compression helical spring on its top, when pin loosened pedal, helical spring restoring force then promoted to stretch and moves on the bar, and the upper end straight-bar is stretched again and inserted in coil and the magneto sensor induction region, motor speed is returned to zero, by the control circuit braking of can discharging rapidly.
The utility model adopts the magneto-electric inducing method to carry out speed and regulates, and has contactless, long-life, economical and practical advantage, amplifies, can improve after the feedback stability of control system through signal.In addition, the utility model adopts spiral shell to put the formula spring structure, satisfies straight line speed governing instructions for use the utility model that industrial sewing machine tramps with one's feet moving and also is applicable to use occasions such as electric power power assist vehicle.
Description of drawings
Fig. 1 is the schematic perspective view of the utility model broken section.
The specific embodiment
Embodiment of the present utility model as shown in drawings.
Below in conjunction with accompanying drawing the utility model is specified.See by figure, the utlity model has one and be located at the magnetoelectric induction device that slot type support 1 on the sewing machine frame 8, a stretching bar 2, a helical spring 3 and are made of coil 5, magnetosensitive sensing element 7 and magnet steel 6; Stretching bar 2 is a stock body, has a circle convex circumference 4 at an upper portion thereof, and a straight-bar is extended in convex circumference 4 tops, is equipped with magnet steel 6 on this straight-bar, and convex circumference 4 bottoms are the stock part of stretching bar 2, are provided with a cable traction post 9 in its lower end; The stock of stretching bar 2 is erected in the notch of slot type support 1 after partly going up tandem arrangement one helical spring 3, and its upper end straight-bar (that is magnet steel) can be stretched insert the coil 5 and the magneto sensor induction zone of the magnetoelectric induction device that is arranged in its top.
