Description
Technical field
The present invention relates to a kind of Computerized flat knitting machine knitting needle, especially relate to a kind of two segments combined Computerized flat knitting machine knitting needle, be mainly used in the Computerized flat knitting machine.
Background technology
Computerized flat knitting machine knitting needle commonly used at present mostly is integral structure, in the use of Computerized flat knitting machine knitting needle, the phenomenon of damaging has appearred as if any one position on the Computerized flat knitting machine knitting needle, just need to change whole Computerized flat knitting machine knitting needle, thereby increased production cost, cause resource to be difficult to obtain reasonable use, be unfavorable for energy-saving and emission-reduction.What is more important, in order better to control and use knitting needle, generally believe the structure of pin bell on the knitting needle must be provided with very firm in the art, can be convenient to control like this and use knitting needle, in case the striker phenomenon occurs, the pin bell on the knitting needle will damage bottom plate triangular, thereby influences the precision of bottom plate triangular, even situations such as head distortion, the fracture of needle plate triangle, the service life of reducing Computerized flat knitting machine greatly also can appear.
The Computerized flat knitting machine knitting needle that fabricated structure is also arranged at present, as open day was on November 04th, 2009, publication number is in the Chinese patent of CN101570914, a kind of knitting needle combination that is applicable to electromagnetic needle selection is disclosed, this knitting needle combination that is applicable to electromagnetic needle selection is made up of needle jack and latch needles, the rear end downside or the front end upside of needle jack matrix are provided with electromagnetism adhesive face, be provided with interlocking portion and elastic rod at its matrix downside, needle jack is combined into one by interlocking portion and latch needles interlocking on it, and wherein the upside of needle jack is provided with one and accepts the pin heel that knitting cam pushes against.The needle jack of this knitting needle has only a pin bell, though corresponding cam mechanism only need push against control to this pin bell, no longer need to consider the correspondence position relation when two pin bells are controlled respectively during the corresponding control of design triangle, but, the applicable surface of this kind knitting needle is narrower, versatility is relatively poor, be difficult to obtain sufficient promotion and application, and using when Computerized flat knitting machine in the process of this kind knitting needle, in case the striker phenomenon occurs, the pin bell on the needle jack will damage bottom plate triangular, thereby influences the precision of bottom plate triangular, even head distortion also can appear, situations such as needle plate triangle fracture, the service life of reducing Computerized flat knitting machine greatly.
For another example, open day is on 01 20th, 2010, publication number is in the Chinese patent of CN101629355, a kind of knitting needle combination is disclosed, this knitting needle combination is made up of needle jack and latch needles, the matrix downside of needle jack is provided with elastic rod, and the front end of matrix downside is provided with interlocking portion, and the rear end is provided with electromagnetism adhesive face; Latch needles places the needle jack front end, and its needle body is provided with scarfing slot; Needle jack and latch needles link into an integrated entity by the chimeric of interlocking portion and scarfing slot on it, and wherein the latch needles needle body is provided with and is used for the preceding pin heel that pushed against by knitting cam, and needle jack matrix upside is provided with at least one and is used for pin heel of being pushed against by knitting cam.This knitting needle combination with former be arranged on the needle jack before, back pin heel is separately positioned on knitting needle and the needle jack, when knitting cam is done the time spent to the preceding pin heel on the knitting needle, only latch needles is moved up and down along needle tray, needle jack is rotated, back pin heel is not rotated the anxiety that falls into needle tray because of needle jack, but, using when Computerized flat knitting machine in the process of this kind knitting needle, in case the striker phenomenon occurs, the pin bell will damage bottom plate triangular, thereby influence the precision of bottom plate triangular, even head distortion also can appear, situations such as needle plate triangle fracture in the service life of reducing Computerized flat knitting machine greatly, this shows, the security performance of such knitting needle combination is not high, is difficult to promote the overall performance of Computerized flat knitting machine.
In sum, also do not have a kind of reasonable in design at present, easy to use, production cost is low, and the security performance height can be made rational use of resources and can effectively be promoted the knitting needle of Computerized flat knitting machine overall performance.
Summary of the invention
