Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed a kind of front lever of presser foot lifter of Sewing machines, and it is simple in structure, easy and simple to handle, can realize the associating lifting of sewing-machine foot and rear tugboat.
The purpose of this utility model can realize by following technical proposal: lever before a kind of presser foot lifter of Sewing machines, described Sewing machines comprises that knee carries presser foot lifter pull bar, rear tugboat, presser feet and for promoting the presser foot lifter cam of presser feet, it is characterized in that, before described presser foot lifter, lever comprises cylindric location axial region, for carrying lever portion that presser foot lifter pull bar is connected and lifting bar portion for being connected with presser foot lifter cam with knee, described lever portion and lifting bar portion are shaft-like and crossing being positioned on perpendicular, described location axial region horizontally set and be vertically connected on lever portion and the cross-shaped portion of lifting bar portion on, on the axial region of described location, be connected with the rear tugboat lifting lever of tugboat lifting after driving.
In the technical program, can carry presser foot lifter pull bar by knee and act in lever portion, make the axial rotation of the front lever of presser foot lifter around location axial region, and make rear tugboat carry out lifting; Also can be by presser foot lifter cam wheel in lifting bar portion, make the axial rotation of the front lever of presser foot lifter around location axial region, and make rear tugboat carry out lifting.
Before the presser foot lifter of above-mentioned Sewing machines, in lever, the sidewall of described location axial region has an output locating surface, and described output locating surface is made as plane, and described rear tugboat lifting lever is sleeved on output locating surface.When lever stress before presser foot lifter can drive output locating surface with equal angular rotation in the time locating the axial rotation of axial region, thus tugboat lifting after driving.
Before the presser foot lifter of above-mentioned Sewing machines in lever, in described lifting bar portion, be connected with one for connecting sewing-machine foot and can driving the pressure foot lifting plate of sewing-machine foot lifting.In the time that lever before presser foot lifter rotates, lifting bar portion is upturned, and can drive pressure foot lifting plate to move up, and sewing-machine foot can upwards rise along with pressure foot lifting plate, and vice versa.
Before the presser foot lifter of above-mentioned Sewing machines, in lever, the angle between described lever portion and lifting bar portion is 60～120 °.
Before the presser foot lifter of above-mentioned Sewing machines, in lever, the angle between described lever portion and lifting bar portion is 90 °.
Compared with prior art, the utility model is simple in structure, the lifting structure of presser feet and rear tugboat is united two into one, thereby the interlock knee of having realized presser feet and rear tugboat is put forward effect, practical, and it only needs the structure of lever before presser foot lifter to change, and do not need original Sewing machines internal structure to transform on a large scale, transformation difficulty is low, and improvement cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation one of the present utility model.
Fig. 2 is structural representation two of the present utility model.
Fig. 3 is the scheme of installation of the utility model and rear tugboat.
In figure, 1, lever portion; 2, lifting bar portion; 3, location axial region; 3a, output locating surface; 4, rear tugboat; 5, rear tugboat lifting lever; 6, pressure foot lifting plate; 7, presser foot lifter lobe plate.
The specific embodiment
Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
With reference to Fig. 1, Fig. 2 and Fig. 3, the present embodiment is the front lever of a kind of presser foot lifter of Sewing machines, can realize the interlock knee of presser feet and rear tugboat and put forward effect, before this presser foot lifter lever comprise cylindric location axial region 3, for carrying lever portion 1 that presser foot lifter pull bar is connected and lifting bar portion 2 for being connected with presser foot lifter cam with knee, in lifting bar portion 2, be connected with one for connecting sewing-machine foot and can driving the pressure foot lifting plate 6 of sewing-machine foot lifting, the below of pressure foot lifting plate 6 is provided with a presser foot lifter lobe plate 7.Lever portion 1 and lifting bar portion 2 are shaft-like and crossing being positioned on perpendicular, location axial region 3 horizontally sets, one end of location axial region 3 is used for being hinged on Sewing machines, the other end is vertically connected on the cross-shaped portion of lever portion 1 and lifting bar portion 2, on the middle part sidewall of location axial region 3, have one for connecting the output locating surface 3a of rear tugboat lifting lever 5, this output locating surface 3a is made as plane, and rear tugboat lifting lever 5 is sleeved on output locating surface 3a above and can rotates and tugboat 4 liftings after driving along with lever before presser foot lifter.
