Abstract
The invention belongs to the technical field of accessories of sewing machines, in particular to an eccentric pin for a take-up lever. The eccentric pin comprises a lever body I and a lever body II, wherein one end of the lever body I is connected with one end of the lever body II; the axis of the lever body I is eccentric to that of the lever body II; and more than two positioning planar slots which are arranged at intervals are formed in the outer surface of the lever body II. According to the eccentric pin disclosed by the invention, the axis of the lever body is eccentric to that of the lever body; requirements of various fabrics with different thicknesses can be met by more than two planar slots formed in the lever body II, so that the generality is enhanced and the simplicity and the convenience in operation are improved. The eccentric pin is suitable for various lockstitch sewing machines.
Description
Technical field:
The invention belongs to Sewing machines accessory technical field, refer in particular to a kind of thread take-up tension lever cam pin.
Background technology:
The effect of thread take-up tension lever assembly is in each work period of stitching forming process, controls the thread take-up tension lever supply and reclaims appropriate upper thread, and the stitching that upper thread and bottom line are formed tightens up, and extracts the needed line amount of using of stitching out from spool.To regulate the stroke of thread take-up tension lever by the offset of change thread take-up crank in prior art.When making the fabric of different-thickness, the stroke of thread take-up tension lever is also different, just needs to regulate to realize by changing thread take-up crank, and it is very inconvenient to operate.
Summary of the invention:
The purpose of this invention is to provide a kind of highly versatile, applicable to the thread take-up tension lever cam pin of different-thickness fabric.
The present invention is achieved in that
A kind of thread take-up tension lever cam pin includes the body of rod one and the body of rod two, and an end of the body of rod one is connected with an end of the body of rod two, and the eccentric axis setting of the axis of the body of rod one and the body of rod two is provided with at the outer surface of the body of rod two the plane of orientation groove that two above intervals arrange.
Above-mentioned plural plane of orientation groove arranges along the face of cylinder spiral of the body of rod two.
The other end of the above-mentioned body of rod one is provided with the convex edge.
The advantage that the present invention gives prominence to compared to existing technology is:
The body of rod one of the present invention is set for the eccentric with the axis of the body of rod two, can satisfy the fabric of various different-thickness by the plural planar slot that arranges on the body of rod two, has strengthened versatility, has improved the simplicity of operation, is applicable on various flat seam machine.
Description of drawings:
Fig. 1 is one of schematic diagram of the present invention;
Fig. 2 is two of schematic diagram of the present invention.
The specific embodiment:
The invention will be further described with specific embodiment for the below, referring to Fig. 1-2:
A kind of line-choosing connecting rod cam pin, include the body of rod 1 and the body of rod 2 20, one end of the body of rod 1 is connected with an end of the body of rod 2 20, and the eccentric axis setting of the axis of the body of rod 1 and the body of rod 2 20 is provided with at the outer surface of the body of rod 2 20 planar slot 30 that two above intervals arrange.
Above-mentioned plural planar slot 30 arranges along the face of cylinder spiral of the body of rod 2 10.Angle between the setting of planar slot 30 and planar slot 30 can be regulated and make the required thread take up lever stroke of various fabrics.Form anchor point on planar slot 30.During use, on sewing machine case corresponding to the plane between air line distance be provided with adjustment screw one to one, when selecting different thread take up lever stroke, realize on corresponding planar slot 30 by screw-driving.
The other end of the above-mentioned body of rod 1 is provided with convex edge 40.Convex edge 40 and the body of rod one 10 axis conllinear.
Above-described embodiment is only one of preferred embodiment of the present invention, is not to limit practical range of the present invention with this, therefore: all equivalences of doing according to shape of the present invention, structure, principle change, within all should being covered by protection scope of the present invention.
