Detailed description of the invention
As shown in Figure 1 and Figure 2, the head of sewing machine of the built-in foot lifting mechanism of the present invention, comprises head 100, and head 100 forms the uprights 110 that is positioned at left side; Oscillating deck 2 is provided with in uprights 110;
As shown in Figure 3, the middle part of oscillating deck 2 is stiff end, and upper end is promote-side 23, and lower end is for pulling end 22; The stiff end of oscillating deck 2 offers hole, axle position 21, and the stiff end of oscillating deck 2 is fixedly connected with head 100 by axial screw 3; Oscillating deck 2 can swing flexibly around its stiff end;
The end 22 that pulls of oscillating deck 2 connects the head of straight-bar 12, and the afterbody of straight-bar 12 connects linear actuator 1; Linear actuator 1 can drive straight-bar 12 transversely straight reciprocating motion, thus drives the end 22 that pulls of oscillating deck 2 to swing around its stiff end;
Linear actuator 1 is fixedly installed in uprights 110 by fixed mount 11;
The connected mode pulling end 22 and straight-bar 12 of oscillating deck 2, can adopt the connection of gathering sill and pin; Namely the end 22 that pulls of oscillating deck 2 offers gathering sill, and be movably set with pin in gathering sill, pin is fixedly connected with the head of straight-bar 12, and pin can slide along gathering sill;
Also the connection of guide rail and pin can be adopted; Namely the end 22 that pulls of oscillating deck 2 is provided with guide rail, and guide rail is movably set with pin, and pin is fixedly connected with straight-bar 12, and pin can along slide;
Linear actuator 1 can be electromagnet, and the side of straight-bar 12 arranges back-moving spring; During electromagnet energising, drive straight-bar 12 to left movement; During electromagnet power-off, back-moving spring makes straight-bar 12 reset;
