Abstract
The utility model discloses an improved latch needle. The improved latch needle comprises a needle head, a needle neck, a needle body and a needle tail, wherein the needle head comprises a needle hook and a needle tongue, a small hole is formed in the needle neck on an a face of the latch needle in a direction towards the needle head, a tiny end of a first leaf spring is inserted in the small hole, the other end of the first leaf spring is fixedly arranged on the needle body, a stripped groove is arranged in the middle part of the needle body on a b face of the latch needle, a second leaf spring is arranged in the groove, one end of the second leaf spring towards the needle tail is inserted in the groove, and the other end of the second leaf spring is fixedly arranged in the groove. According to the improved latch needle, the contact area between the second leaf spring and the needle groove is increased, and stable operation of the latch needle in the needle groove is ensured through the tension of the leaf springs, so that weaving accuracy is ensured, durability of the leaf springs is improved, and the needle tail of the latch needle does not need to form into an arc shape.
Description
Technical field
The utility model relates to the flat machine technical field, particularly relates to a kind of improved latch needles.
Background technology
At present; The backshank of tradition latch needles is processed as arc-shaped bend, leans on backshank a bit to contact with the one side (inserted sheet) of loom needle tray, and purpose is for fear of the effect of inertia of latch needles in needle tray; But such latch needles is stable at work unsatisfactory, and the braiding precision can not guarantee; The spring leaf of tradition latch needles adopts punching press riveted way and needle body to be processed in together; For the ease of the punching press of spring leaf, the points hardness of needle body decreases, simultaneously; In the traditional handicraft, the punching press of spring leaf is the link firmness of control spring sheet and needle body effectively.
Summary of the invention
The problem that the utility model need solve is, at work stable undesirable of traditional latch needles, and the braiding precision can not guarantee that the link firmness of spring leaf and needle body is strong inadequately.
In order to address the above problem, the utility model provides a kind of improved latch needles, and it comprises syringe needle, pin neck, the needle body and the backshank that sets gradually; Syringe needle comprises pinhock and needle latch, and at a of latch needles face, the pin neck is having an aperture on the direction of syringe needle; The end that first spring leaf is tiny is plugged in this aperture, and the other end is fixedly installed on the needle body, at the b of latch needles face; The middle part of the needle body is milled with a strip shape groove; Be placed with second spring leaf in the groove, second spring leaf is plugged in the groove towards an end of backshank, and the other end is fixedly installed in the groove.
The further improvement of the utility model is: first spring leaf is fixedly installed on the end that an end and second spring leaf on the needle body be fixedly installed in the groove and all is arranged on the needle body through welding.
The mid portion projection of first spring leaf 3 is higher than the horizontal plane of the latch needles a face needle body, and the mid portion projection of second spring leaf 5 is higher than the horizontal plane of the latch needles b face needle body.
Backshank is straight.
When latch needles is worked in lathe, be embedded in the middle of two inserted sheets, the gap between two inserted sheets is slightly larger than the thickness of the latch needles needle body; Because latch needles in the braiding process, receives the external force effect of lathe triangle, the reciprocal knitting campaign of in inserted sheet, going up and down;, in needle tray, be free to slide, therefore owing to its own inertial for fear of knitting needle; In the needle body groove milling of latch needles, and install a spring leaf additional.Therefore, because the tension force of spring leaf has avoided latch needles in inserted slot, to be free to slide, improved the stability of latch needles, the elongated slot that on needle body, mills has also strengthened the elasticity of needle body, can effectively reduce latch needles impact injury to pinhock and needle latch in the braiding process.Latch needles after the improvement, the contact-making surface of spring leaf and needle tray is big, utilizes the tension force of spring leaf better to make latch needles steady operation in needle tray, has guaranteed the braiding precision, has improved the durability of spring leaf, and the backshank of latch needles also needn't be processed as arc.

Wherein, 1-pinhock, 2-needle latch, 3-first spring leaf, 4-groove, 5-second spring leaf.
The specific embodiment
The utility model discloses a kind of improved latch needles, it comprises syringe needle, pin neck, the needle body and backshank, and syringe needle comprises pinhock 1 and needle latch 2; At a of latch needles face, the pin neck is having an aperture on the direction of syringe needle, and first spring leaf, 3 tiny ends are plugged in this aperture; The other end is fixedly installed on the needle body; At the b of latch needles face, the middle part of the needle body is milled with a strip shape groove 4, is placed with second spring leaf 5 in the groove 4; Second spring leaf 5 is plugged in the groove 4 towards an end of backshank, and the other end is fixedly installed in the groove 4.
An end and second spring leaf 5 that first spring leaf 3 is fixedly installed on the needle body are fixedly installed on the end in the groove, all are arranged on the needle body through welding.
The equal projection of mid portion of first spring leaf 3 and second spring leaf 5 all is higher than the horizontal breadth of the needle body.
Backshank is straight.
Latch needles after the improvement adopts welding procedure that first spring leaf and needle body are linked together, and has strengthened the degree of being connected firmly of first spring leaf and needle body greatly; Need not reduce simultaneously the hardness of needle body again; On the needle body of latch needles, install second spring leaf additional, make the contact-making surface of spring leaf and needle tray big, avoided latch needles in inserted slot, to be free to slide; Utilize the tension force of spring leaf better to make latch needles steady operation in needle tray; Guaranteed the braiding precision, improved the durability of spring leaf, the strip shape groove that on needle body, mills has also strengthened the elasticity of needle body; Reduced latch needles in the braiding process to the impact injury of pinhock and needle latch, the backshank of latch needles also needn't be processed as arc.
