The utility model discloses the tooth frame motion is assisted, makes tooth frame motion steady, avoids tooth frame to cause the work feed inhomogeneous, the work feed phenomenon such as not smooth.
Description
Technical field
The utility model belongs to lock-type chain stitch flat seam machine technical field, relates to a kind of crank of three-needle lock stitch seam plaining machine.
Background technology
Sewing machine for covering chain stitch mainly is with a sewing thread, on sewing, forms a kind of stitching, the machine that makes one or more layers sewing interweave or unite by a seam; Usually make thin material and thick material and make purposes for two kinds, sewing machine for covering chain stitch can make post such as cotton, fiber crops, silk, hair, artificial fibre or make, goods such as leather, plastics, paper; The shuttle that bottom line is housed in flat seam machine wears among formed line one ring of eedle line, has formed lock-type chain stitch.
In recent years; The flat seam machine that a kind of single needle or crosspointer lock-type chain stitch on the existing market, occur; It is connected the strip shape body that retainer in the flat seam machine is generally arc; This retainer is located at a side of single rotating shuttle or between two rotating shuttles, but because the develop rapidly of clothes industry, and the trivial formula flat seam machine of two pins has not reached market for the increasingly high designing requirement of ornamental seam.
To above-mentioned this situation, a kind of flat seam machine of three pin lock-type chain stitchs has appearred on the existing market, and the retainer of this flat seam machine will carry out from new design in the flat seam machine retainer of traditional single needle or crosspointer; The structure of the flat seam machine through three pin lock-type chain stitchs shows it is that a side between left-handed shuttle and dextrorotation shuttle is set up rotating shuttle in, its retainer to give middle rotating shuttle one let bit space, the retainer of the flat seam machine of existing three pin lock-type chain stitchs generally be around in a side of rotating shuttle; Its requirements of installation space is higher; Also have retainer when motion, motion is unstable, can cause the retainer work feed inhomogeneous; Phenomenons such as work feed is not smooth have a strong impact on the Sewing machines performance.
Summary of the invention
The purpose of the utility model is to existing deficiency, and a kind of crank that makes the more steady three-needle lock stitch seam plaining machine of retainer swing is provided.
The purpose of the utility model can realize through following technical proposal: a kind of crank of three-needle lock stitch seam plaining machine; The block crank body of bar shaped that comprises integrative-structure; It is characterized in that offer one at an end of crank body and can be connected the hinge hole on the retainer through jointed shaft, the center line that is parallel to hinge hole at the middle part of crank body is offered a connecting hole; Described connecting hole is formed with an armful arm two by embracing arm one; This armful arm one forms a prong with armful arm two, offers fixing hole two at armful arm one with embracing on the arm two, and this fixing hole two passes an armful arm one and an armful arm two successively.
The crank of this three-needle lock stitch seam plaining machine is offered a hinge hole and a connecting hole; Being provided with a jointed shaft at hinge hole can be connected crank on the retainer; Can be provided with a connecting axle at connecting hole crank is connected with frame, this crank is assisted retainer motion work, makes the retainer centre of motion stable; Prevent that retainer from rocking, and promotes the effect of making of flat seam machine when motion.
In the crank of above-mentioned three-needle lock stitch seam plaining machine, be horizontally disposed with above-mentioned hinge hole at crank body, this hinge hole runs through the and arranged on left and right sides wall of crank body.This hinge hole is a through hole.
In the crank of above-mentioned three-needle lock stitch seam plaining machine, on crank body, be provided with the fixing hole one that is connected with hinge hole.This fixing hole one is vertical each other with hinge hole.
In the crank of above-mentioned three-needle lock stitch seam plaining machine, described armful of arm one is symmetrically distributed with armful arm two.
In the crank of above-mentioned three-needle lock stitch seam plaining machine, described fixing hole two is perpendicular to the center line of connecting hole.This fixing hole two runs through to be embraced arm one and embraces arm two, and is positioned at the middle part of embracing arm one and embracing arm two.
Compared with prior art; One end of the crank of this three-needle lock stitch seam plaining machine offers one can be connected the hinge hole on the retainer through jointed shaft; The center line that is parallel to hinge hole at the middle part of crank body is offered a connecting hole, and this crank aids in the retainer motion, makes the retainer motion steadily; Avoid retainer to cause work feed inhomogeneous, phenomenon such as work feed is not smooth.
