The specific embodiment

Extremely shown in Figure 5 as Fig. 1, the utility model provides a kind of color change head work latch structure, this color change head can be installed on the tubular knitting machine, and be subjected under promotion track 27a and the control that promotes track 27b and needle selection device 28 on the knitting machine rotation platform, knitting needle is made the hello yarn action of coloured yarn, thereby the pattern that makes the cloth that weaves have different colours presents.

Described work latch structure is arranged on the fixed platform of body color change head 21 tops, being divided into two assemblings places in the corresponding installing hole of fixed platform, yarn-pushing plate 22 tops of the corresponding color change head of one group of work latch structure wherein, the top of other one group of corresponding impeller 23 makes the promotion track make downward pushing action by the work latch structure to the yarn-pushing plate and the impeller of body color change head.Described work latch structure comprises: work pin 6, work pin 7, pivot 20, through hole 17, conflict part 8, conflict part 9, rolling bearing 12, pivot 10, nut 14, meson 11, split ring meson 13, oil-containing guide 4, oil-containing guide 5, sliding space 18, sliding space 19, spring 15, spring 16, promote triangle 1, connecting hole 1a, connecting hole 1b, fixedly pin member 2, fixing pin member 3.This rolling bearing 12 can be rolling members such as roller, this rolling bearing 12 can be located at two upper ends between the work pin rotationally and articulate face 20, article two, the pivot joint face of work pin upper end is respectively equipped with through hole 17,17a, this rolling bearing 12 is arranged in through hole 17,17a on the pivot joint face 20 with a pivot 10, and is locked with nut 14.Connect between face and the rolling bearing in work pin the stingy of 6 upper ends in addition, be respectively equipped with meson and split ring meson between the pivot joint face of rolling bearing and work pin 7 upper ends and between the pivot joint face 20 of these work pin 7 upper ends and this nut.Be provided with split ring meson 13 between the pivot joint face 20 of described work pin 7 upper ends and this nut 14, the effect of this split ring meson 13 can prevent that this nut 14 is loosening.

This conflict part 8,9 is special c type jump ring, is sheathed on respectively above the

work pin

6,7, and described

spring

15,16 is sheathed on

work pin

6,7 outsides respectively, and is resisted against below the conflict part 8,9, and press on above the oil-containing guide for the compression spring.Described oil-containing guide respectively is fixedly arranged on the fixed platform in the corresponding with it installing hole.Acting as when promoting

track

27a, 27b release motive force of described

spring

15,16, its

spring

15,16 can move up pin and reset.Be respectively equipped with sliding space in the described oiliness bearing, and the work pin can be sheathed on slidably in this sliding space, makes the upper and lower slip of work pin more smooth and easy, and can reduce friction.

Described promotion triangle 1 is plate body, is respectively equipped with the connecting hole 1a, the 1b that connect two work pins in this impeller, and with two fixedly pin member two work pins be fixed on promote on triangle two connecting hole 1a, 1b.

From the above, two work pins top and followingly all have spare part to connect together respectively, so also can play the check and correction that is parallel to each other, the phase mutual designation moves, and not yielding.

Comprehensive as can be known above-mentioned, the work latch structure of utility model color change head, can make the upper and lower slip of its work pin more smooth and easy, not yielding, prevent the wearing and tearing that produce between the spare part, the pin of will working simultaneously, pivot, the life-span that reaches oiliness bearing is enhanced about more than once than work on hand latch structure.

The above only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model is to any simple modification that above embodiment did, equivalent variations and modification all still belong in the scope of technical solutions of the utility model.
