Abstract
The utility model relates to a needle for a sewing machine. A positioning protecting notch is respectively arranged on a needle bar and a taper shank along the axis direction, and is relative to the position of a long line slot. Thus the notch is higher than a needle hole, and relative stress is concentrated. The position fracture can be realized, and the defect that a plus material is damaged because the needle is broken from the pin hole of the prior art can be overcome.
Description
The utility model relates in a kind of field of textiles, sewing, embroidery eedle.
The eedle that uses in industrial sewing and the machine embroidery industry is made up of three parts usually at present, and it is followed successively by needle handle, taper shank and shank from top to bottom, and wherein the lower end of shank is a needle point, and the upper end of needle point is a pin hole, and the pin hole both sides of shank are provided with long wire casing and stub.The eedle of this structure, in use, if when misoperation or used line material have the quality flaw, rupture easily, and the position of fracture is at the pin hole place " broken hole " that causes broken needle on lining, to stay thus can't remedying, make and bring certain economic loss by goods degree of work.
The purpose of this utility model is to overcome above-mentioned defective, provides a kind of eedle fracture that prevents to contact with lining, thus the eedle of avoiding " broken hole " to occur.
The utility model improves realization on the prior art basis, along axis direction, and be provided with to locate with respect to long wire casing position and protect otch in shank middle and upper part and needle handle transition awl district.
Protection otch in location is curved, and its corresponding arc radius is that the circular arc degree of depth is no more than 1/3rd of shank diameter between 23 to 25 times of shank diameter, and its width is no more than half of shank diameter.
Location protection otch is positioned at the top of needle handle transition awl district and shank.
Location protection otch also can be positioned at the middle and upper part of shank.
After adopting the utility model; owing to be provided with the location protection otch that stress is concentrated, and this incision site is higher than pin hole, when operation is obstructed or is subjected to excessive external force radially tractive makes pin produce moment of flexure to baffle; eedle ruptures from location protection incision, and can not injure lining.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a cut-away view of the present utility model;
Fig. 2 is the utility model A-A cut-away view.
Referring to Fig. 1, it is made up of three parts, and it is followed successively by needle handle 1, taper shank 2 and shank 3 from top to bottom, and wherein the lower end of shank 3 is a needle point 4, and the upper end of needle point 4 is a pin hole 5, and pin hole 5 both sides of shank 3 are provided with long wire casing 6 and stub 7; Referring to Fig. 2, along axis direction and with respect to long wire casing 6 positions protection otch 8 in location is set on the top of shank 3 and taper shank 2 places in needle handle transition awl district; Location protection otch 8 is curved; its corresponding arc radius R is between 23 to 25 times of shank 3 diameters; the circular arc degree of depth is no more than 1/3rd of shank 3 diameters, and the circular arc bosom is positioned at the junction of taper shank 2 and shank 3, and the width of location protection otch 8 is no more than half of shank 3 diameters.
The utility model; the cross section bilateral symmetry; axially loaded is evenly distributed; when normal operation; enough mechanical strengths and good axial stability are arranged, can be because of the performance that influence eedle that is provided with of location protection otch, when operation is obstructed or is subjected to excessive external force radially tractive baffles pin generation moment of flexure; eedle ruptures from location protection incision, thereby can not injure lining.
