Abstract
A sewing needle comprises a petiole for holding, a rod extending forward from the petiole and a tip on the front-end of the rod. The petiole, rod and tip form a joint structure with a center line. A needle eye is arranged at the connection of the rod and tip, an incoming line groove extending from the needle eye to the petiole is arranged on the one side of the rod, an outgoing line groove is arranged at the tip and on the opposite side of the incoming line groove. The model is characterized in that the incoming line groove and outgoing line groove are deepened to their bottom and extended to the needle eye so as to form a gap at the section direction. Therefore the model avoids the bent appearance caused by the wire passing through the needle eye and any other defects, which is applicable for middle-rough wire particularly.
Description
Technical field
The utility model relates to a kind of sewing machine needle, this eedle have the buckling phenomenon that forms when bigger advantage is used for containing the tailor-tacking line and avoids suture to pass pinprick and the sewing process that causes by buckling phenomenon in some other defectives.
Background technology
Patent documentation CN1499005A (application number: 200310104333.0) disclose a kind of " sewing machine needle ", its specification has been made classification to existing sewing machine and has been pointed out the characteristics and the defective of dissimilar Sewing machiness respectively, and a kind of sewing machine needle 5 is provided, this sewing machine needle is no matter high speed and multi-functional Sewing machines and various employed material can both prevent to jump the yarn breakage of circle and textiles.
Patent documentation CN1386149A (application number: 01801964.1) disclose a kind of " Sewing needles ", it is the design from wire casing, when the wire casing profile that helps fine rule guiding is provided, and Sewing needles that more can impedance flecition power.
Also have many other documents to put down in writing technological improvement from different angles respectively, but do not disclose technological deficiency and relevant solution that existing eedle that the application hereinafter mentions exists sewing machine needle.
Development along with technology, Social Culture is improving equally, single from dress ornament, aforesaid eedle structure has been difficult to satisfy the requirement of sewing fashion dress ornament: when interspersing suture as making on dress ornament, then the eedle because of aforementioned structure is applicable to middle finedraw line (401-20/3 is following) more, if be used for tailor-tacking line (2000D/3 and knitting wool), then following defective can take place: (1) eedle is difficult to effectively contain suture; Form the serpentine radian when (2) suture passes pinprick; Resistance when (3) suture and eedle pass sewing is bigger; (4) easily sewing is caused damage; (5) cause the broken string phenomenon; (6) working long hours afterwards, eedle easily generates heat.And the influence that causes by above-mentioned reason to final products (as dress ornament) quality.
The utility model content
The technical problem that the utility model will be separated and the technical assignment of proposition are to overcome the defective that existing eedle is not suitable for middle tailor-tacking line, a kind of sewing machine needle is provided, so as to have the buckling phenomenon that forms when bigger advantage is used for containing the tailor-tacking line and avoids suture to pass pinprick and the sewing process that causes by buckling phenomenon in some other defectives.For this reason, the utility model is taked following technical proposals:
A kind of sewing machine needle, comprise the shank that is used for clamping, from bar portion that shank extends forward and the point that is positioned at bar portion front end, described shank, bar portion and point form the integrative-structure with center line (O-O), joint portion at described bar portion and point offers pinprick, side in described bar portion offers the inlet wire groove that extends to shank from described pinprick, on described point, offer out wire casing, it is characterized in that described inlet wire groove with the opposing side of inlet wire groove, going out wire casing deepens to extend to described pinprick to the bottom land of the two and is in and forms the gap on the cross-wise direction.
Described inlet wire groove, the bottom land that goes out wire casing and described center line form angle respectively.
The described cross section that goes out wire casing is
Shape.
The bottom surface of described inlet wire groove is the plane.
The cross section of described inlet wire groove is
Shape.
Described inlet wire groove closes on the width D and depth H coincidence formula: the 1.5H≤D≤4H at pinprick place.
Described bar portion has the concave section in the inlet wire groove one side position of closing on pinprick dorsad.、
Described pinprick be of a size of 1.5～3 times of its lateral dimension at centerline direction.
The utility model by with the inlet wire groove, go out wire casing and deepen to extend to pinprick and be in and form the gap on the cross-wise direction to the bottom land of the two, thereby some other defectives in buckling phenomenon that forms when effectively avoiding suture to pass pinprick and the sewing process that causes by buckling phenomenon, tailor-tacking line in being particularly useful for.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
