Abstract

The utility model discloses a kind of knitting needle, comprise shank, pinhock and the needle latch for closing pinhock, described pinhock comprises the first pinhock and the second pinhock, described first pinhock and the second pinhock junction are provided with transition arc, yarn can be made to move to the second pinhock from the first pinhock by rotating needle latch.Use the first pinhock to be pierced into by yarn when entrying, then needle latch is rotated further, make the projection of needle latch that yarn is moved to the second pinhock stably, because the opening of the second pinhock is smaller, so when coil breaks off relations more easily and can not coil be widened; Transition arc can be made up of materials such as silica gel, can not damage coil like this when unhook, makes the effect of unhook better.

Description

A kind of knitting needle

Technical field

The utility model relates to a kind of knitting needle, especially a kind of knitting needle comprising two pinhocks.

Background technology

Knitting needle is the main loop-forming element of one on knitting machine, by steel wire or steel band is machined makes, for yarn being woven into coil and making coil string cover connect into knitted fabric.The structure of knitting needle and shape affect knitting knitting cycle, the productivity ratio of knitting machine and the quality of product, are the important evidence of knitting machine design.

For the improvement of the knitting needle of knitting machine, face two conflicting technical requirements at present: on the one hand in order to make the yarn that must insert in pinhock be hooked by pinhock more securely, pinhock should be large as far as possible.On the other hand in order to make the easy knocking over when pinhock is closed of the coil of formation, pinhock should be little as much as possible, because large pinhock can cause coil seriously to be widened.

In prior art, one compromise is carried out to these two kinds of requirements, but it not best for the knocking over of entrying with coil.

Utility model content

The utility model aims to provide a kind of knitting needle for knitting machine, and it can either ensure reliably to entry and can ensure stitches better effects if.

For achieving the above object, the technical solution of the utility model is: a kind of knitting needle, comprise shank, pinhock and the needle latch for closing pinhock, described pinhock comprises the first pinhock and the second pinhock, described first pinhock and the second pinhock junction are provided with transition arc, yarn can be made to move to the second pinhock from the first pinhock by rotating needle latch.

Further, the A/F of described first pinhock is greater than the A/F of the second pinhock, and the radian of described transition arc is 90 °-200 °

In order to better can by yarn movement to the second pinhock when rotating needle latch, described needle latch be extended with projection near end to pinhock, and described projection is inclination round slip surface.

Described transition arc is preferably made up of silica gel or metal.

The beneficial effect of the utility model method is: use the first pinhock to be pierced into by yarn when entrying, then needle latch is rotated further, make the projection of needle latch that yarn is moved to the second pinhock stably, because the opening of the second pinhock is smaller, so when coil breaks off relations more easily and can not coil be widened; Transition arc can be made up of materials such as silica gel, can not damage coil like this when unhook, makes the effect of unhook better.

Accompanying drawing explanation

Fig. 2 is the structural representation of the second embodiment of the utility model knitting needle.

Detailed description of the invention

For making the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with detailed description of the invention also with reference to accompanying drawing, the utility model is further described.Should be appreciated that, these describe just exemplary, and do not really want to limit scope of the present utility model.In addition, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily obscuring concept of the present utility model.

As shown in Figure 1, a kind of knitting needle of the present embodiment, comprise shank 1, pinhock 2 and the needle latch 3 for closing pinhock, needle latch 3 is arranged on the link of shank 1 and pinhock 2, described pinhock 2 comprises the first pinhock 22 and the second pinhock 21, described first pinhock 22 and the second pinhock 21 junction are provided with transition arc 23, yarn can be made to move to the second pinhock 21 from the first pinhock 22 reposefully through transition arc 23 by rotating needle latch 3, entry and coil unhook to better solve, the A/F of the first pinhock 22 is greater than the A/F of the second pinhock 21.The circular arc of the first pinhock 22 is preferably close to semi arch, and the circular arc outermost end points of the first pinhock 22 is inside the circular arc outermost end points of the second pinhock 21, and the radian of described transition arc 23 is 90 °-200 °, is preferably 180 °.Transition arc is made of metal.

In order to reach better effect, improve further knitting needle, as shown in Figure 2, in order to better can by yarn movement to the second pinhock 21 when rotating needle latch 3, described needle latch 3 be extended with protruding 31, described protruding 31 for inclination round slip surface near end to pinhock.

The damage of breaking off relations to make coil drops to minimum, and described transition arc upper end 230 is preferably made up of silica gel, and easier when coil breaks off relations like this, effect is also better.

Should be understood that, above-mentioned detailed description of the invention of the present utility model only for exemplary illustration or explain principle of the present utility model, and is not formed restriction of the present utility model.Therefore, any amendment made when not departing from spirit and scope of the present utility model, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.In addition, the utility model claims be intended to contain fall into claims scope and border or this scope and border equivalents in whole change and modification.
