Description
Technical field
The present invention is relevant for a kind of presser foot of Sewing machines, and espespecially a kind of avoiding produces fold after cloth cover sewing, keeps the presser foot of good suture quality.
Background technology
The presser foot of existing Sewing machines, the pressure of its presser feet compacting cloth cover is mostly necessarily, so while pressing the different cloth cover of thickness or the different elastic woven material of material and grenadine cloth, the press power of its presser feet cannot obtain suitable adjustment.Because presser feet cannot suitably be adjusted press power and located cloth cover, therefore face tension is often excessive or too small, make drawing cloth cover that cloth feeding claw cannot be certain forward, therefore after sewing, cloth cover often produces the phenomenon of out-of-flatness and fold, cause suture quality not good.
In order effectively to adjust the compress strength of cloth pressing foot; develop at present the Sewing machines of a kind of coaxially release wire press mechanism and cloth pressing foot pressure control mechanism; as No. 447534 patent of TaiWan, China; it discloses a kind of sewing machine thread press mechanism and cloth pressing foot pressure control mechanism; this patent is set as and can or discharges the form that thread tension direction moves horizontally along compacting in the Control Shaft of thread tension adjusting apparatus, to reach the object that can discharge or suppress suture pressure simultaneously; And be separately provided with line pressure releasing device in controlling the tip of the axis, and make cloth foot-propelled make simultaneously directly connecting move control axle and thread tension adjusting apparatus, with this, discharge or reply the tension force that presses to each suture.
In above-mentioned patent, with so that whole what control that thread tension mechanism coordinates suture earth pressure release is the structure of a complexity, not only make and be difficult for, and overall architecture cost is high, need to be improved in fact.
Summary of the invention
An object of the present invention, is to provide a kind of presser foot of Sewing machines, and it avoids producing fold after cloth cover sewing, to keep good sewing quality.
Another object of the present invention, be to provide a kind of presser foot of Sewing machines, it presses the different cloth cover of thickness or the different elastic woven material of material and the power that presses of grenadine cloth by elastic pressuring plate adjustment, to maintain suitable pressure, cloth cover is suppressed to location.
Another object of the present invention, is to provide a kind of presser foot of Sewing machines, Sewing machines presser foot simple in structure and make easily, not only can reduce the holistic cost of product, and there is good suture quality.
In order to achieve the above object, the invention provides a kind of presser foot of Sewing machines, comprising:
One presser feet platform, comprises a holder and the main pressing plate that extends forward the bottom surface of this holder certainly; And
One elastic pressuring plate, along this main pressing plate, and extending longitudinally, this elastic pressuring plate has a relative stiff end and a free end, and this stiff end is combined on this presser feet platform, and this free end is arranged on the bottom surface of this main pressing plate and is free state.
Further, wherein this stiff end is combined on this main pressing plate.
Further, wherein the front end of this main pressing plate is extended with a kink, and this stiff end is combined on this kink.
Further, wherein this kink has an outward extending skewback, this skewback is provided with a combined hole, this elastic pressuring plate has the buckling parts extending towards this skewback direction bending, this buckling parts is provided with a perforation, this buckling parts button hangs on this skewback, and this perforation is that correspondence is arranged on this combined hole place.
Further, wherein this stiff end is combined on this holder.
Further, wherein this stiff end is combined in the rear of this holder, and this free end is to extend forward towards this main pressing plate direction.
Further, wherein this presser feet platform also comprises at least one movable pressing board, and this at least one movable pressing board is arranged on the side of this main pressing plate.
Further, wherein this presser feet platform comprises a pair of movable pressing board, and this is symmetricly set on the dual side-edge of this main pressing plate to movable pressing board.
Further, wherein the bottom surface of this movable pressing board lower than the bottom surface of this main pressing plate.
Further, wherein this main pressing plate is provided with a pin hole, and this elastic pressuring plate at least extends to this pin hole position and this pin hole of fitting, and this elastic pressuring plate is to pin hole position that should main pressing plate and offer at least one groove of wearing.
Simple in structure and the cost of the presser foot of Sewing machines of the present invention is low, it is mainly that elastic pressuring plate is combined on presser feet platform, and make to extend longitudinally to the bottom surface of main pressing plate and be free state, when sewing cloth is admitted to main pressing plate bottom surface, elastic pressuring plate presses and is treated sewing cloth, is beneficial to carry out sewing; Due to elastic pressuring plate, can put down to be against and treat on sewing cloth, therefore unlikely, apply too much pressure and treating on sewing cloth, with this sewing, go out the second best in quality thread; Moreover, because elastic pressuring plate can become a plane after being pressed with movable pressing board, with this, on average press power, maintain the location for the treatment of that sewing cloth is good, more increased practicality of the present invention.
