(5) specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Embodiment one
With reference to Fig. 1,2,3, a kind of thickness changing sewing needle rod wire selecting mechanism comprises installation panel 1, is fixed in inserting 2, be hinged on the swing hook 3 on the described installation panel 1 on the described installation panel 1, and swing hook 3 is positioned at described 2 the below of inserting.Insert and 2 have recessed locked groove 4, Open Side Down for this locked groove 4, the head of described swing hook 3 has the latch hook 5 with the adaptive bending of described locked groove 4, and the top of described latch hook 5 offers the first threading aperture, is respectively equipped with first Overline ring 6 and second Overline ring 7 on the installation panel 1 of these latch hook 5 both sides.
The head of a described swing hook 3 and a centering block 8 is hinged, described centering block 8 and described 2 both sides that are positioned at described swing hook 3 of inserting, the afterbody of described centering block 8 offers the second threading aperture 9, the 3rd Overline ring 10 that one side of described centering block 8 is distributed with up and down and the 4th Overline ring 11, described first Overline ring, 6-the first threading aperture-second Overline ring, 7-the three Overline ring, 10-the second threading aperture, 9-the four Overline ring 11 constitutes the threading path.
The rear of described centering block 8 also has first extension spring 12 and second extension spring 13, described first extension spring 12 and second extension spring 13 are positioned at the both sides of described swing hook 3, described second extension spring 13 and described the 3rd Overline ring 10, the 4th Overline ring 11 are positioned at the both sides of described centering block 8, the two ends of described first extension spring 12 are affixed with described installation panel 1 and described swing hook 3 respectively, and the two ends of described second extension spring 13 are affixed with described swing hook 3 and described centering block 8 respectively;
Described installation panel 1 is provided with the centering block locating piece 14 that is used to locate described centering block 8, the swing hook locating piece 15 that is used for described swing hook 3 is positioned described locked groove mouth, described centering block locating piece 14 is positioned at the rear of described centering block 8 afterbodys, and the head of described centering block locating piece 14 is provided with positioning step.Described swing hook locating piece 15 and described 2 the same sides that are positioned at described swing hook 3 of inserting are hinged with the one way stop 16 of stirring described swing hook 3 afterbodys when being used for back stitching on the frame, offer the cavity that rotates counterclockwise for described one way stop 16 on the described frame.Promptly move downward when touching one way stop 16 when swing hook 3, one way stop 16 does not stop the motion of swing hook 3, when swing hook 3 moves upward when touching one way stop 16, stirs swing hook 3 thereby one way stop 16 stops the motion of swing hook 3.
During sewing, this sewing needle rod wire selecting mechanism is installed on the shank and moves in company with shank.Down during pricker, swing hook locating piece 15 is positioned at the locked groove mouth with the latch hook 5 of swing hook head and does not enter in 2 the locked groove 4 inserted, and centering block 8 afterbodys are by centering block locating piece 14 location, and can thrust needlework smoothly in the footwear base this moment.During back stitching, block 16 is stirred the afterbody of described swing hook 3, and the latch hook 5 of swing hook head is locked in the locked groove 4, and centering block 8 afterbodys are by the step location of centering block locating piece 14, and the frictional force between latch hook 5 and the locked groove 4 is locked with line at this moment.Line is by after locked, and line and pin hole do not have relative motion, so pin is in backhaul, and just that last pin is unnecessary naturally line amount is regained.When line is all regained, be in tensioning state, when the tension force of line enough spurs centering block 8, and first extension spring 12 is shunk when overcoming frictional force between latch hook 5 and the locked groove 4, latch hook 5 disengaging locked grooves 4, thus enter the line sending state once more.
