Presser foot lifter lever and fixed mount, presser foot lifter lever are articulated on overedger fuselage, and fixed mount is fixed on overedger fuselage, fixed
Be further opened with being plugged with through hole, through hole on frame can around itself axial rotation rotating shaft, foot lifting mechanism also includes conversion thick stick
Bar and chain hook, the inner of shifter lever are fixed at the inner of rotating shaft, the lower end of chain hook and the outer end phase clasp joint of shifter lever, chain
The upper end clasp joint of hook can drive the knee control of the axis of rotation to lean on presser foot lifter lever, being additionally provided with one at the outer end of rotating shaft
A back cushion touched for operator's knee is fixed with bar, knee control rod.Back cushion is touched with knee by operator, knee control is leaned on
Bar is swung, and drives rotating shaft to rotate, and the shifter lever at rotating shaft the inner is rotated, and presser foot lifter thick stick is driven by chain hook
Bar realizes presser foot lifter function to lower swing.The foot lifting mechanism is entirely mechanical structure so that sewing machine it is automatic
Change degree is not high enough, it is impossible to meets the demand of integrated form electromechanical integration sewing machine, and is all from back cushion to final presser feet
Cause the parts of whole foot lifting mechanism more by mechanically operated mode, transmission process is complicated.
In summary, existing knee exists to improve by sensor and required, its function can very easily be realized by being badly in need of one kind
The knee of exterior appearance is not influenceed to lean on sensor again.
Utility model content
The purpose of this utility model is the defect existed for prior art, it is proposed that a kind of automaticity is higher,
More intelligent knee leans on sensor.
To achieve these goals, the technical solution of the utility model is as follows：
It includes knee and leans on disk, connecting rod, fixed seat, oscillating bar assembly and sensor cluster；The knee by disk by connecting rod with
Fixed seat is connected, and the knee is adjustable by position height of the disk on connecting rod；The fixed seat is connected by screw and oscillating bar assembly
Connect, the fixed seat setting angle can adjust；The sensor cluster includes shell, support, and enclosure is provided with group of magnets
Part, PCB, housing exterior are provided with spring, and spring one end is fixed on oscillating bar assembly, and the other end is fixed on shell,
The spring force is adjustable；The oscillating bar assembly is connected through shell with magnet assemblies；Limited location shelves are set on the shell,
Oscillating bar assembly angle is limited, makes oscillating bar assembly stress more reasonable, ensures that correlated parts are without damage, the knee is pressed by lift
Pin Sensor output linearity is high, accuracy is good, simple in construction；Realize height, dynamics, adjustable angle.
The knee leans on sensor, and sewing machine table bottom is fixed on by support, will according to the knee height of producers
Knee arrives correct position by disk regulation.During work, producers' knee touches knee by disk, and oscillating bar assembly is swung, with swing rod group
The connected magnet assemblies of part produce displacement relative to Hall sensor, the electric signal of Hall sensor is changed, the change
The controller of sewing machine is transferred to, controller lifts presser feet according to the signal control motor of change.Solve tradition and lean on manpower
The heavy labor that lifting sewing-machine foot is a large amount of, repeat, realize presser feet can be segmented, accurate, light control.
A kind of handwheel of the present utility model has the following advantages that：
(1) knee leans on sensor, and knee is connected by disk by connecting rod with fixed seat, and the knee leans on position of the disk on connecting rod
It is Height Adjustable.
(2) knee leans on sensor, and fixed seat is connected by screw with oscillating bar assembly, and the fixed seat setting angle is adjustable
Section.
(3) knee leans on sensor, and being provided with three gears on oscillating bar assembly puts, adjustable springs elastic force
(4) knee, which is leaned on sensor, shell, sets limited location shelves, and oscillating bar assembly angle is limited, makes swing rod group
Part stress is more reasonable, ensures that correlated parts are without damage
(5) knee leans on sensor, lifts presser feet by the change controlled motor of Hall electric signal, solves tradition and lean on
The heavy labor that manpower lifting sewing-machine foot is a large amount of, repeat, realize presser feet can be segmented, accurate, light control.
The characteristics of the utility model, see the detailed description of this case schema and following preferable embodiment and obtain clear
Ground understands.
