Description
Technical field
The utility model is related to a kind of novel self-lock pull heads.
Background technology
Referring to Fig.1, a kind of existing self-locked draught part is as shown in Figure 1, the pull head includes slider body 1, pulling-on piece 2 and shrapnel
3, the built-up sequence of the pull head is：First the end 22 of pulling-on piece 2 is placed in the dented space 13 of slider body 1, and pulling-on piece 2 is pushed away
To one end of slider body 1 so that the sets of holes 21 on pulling-on piece 2 fix the first fixed seat 11 or second in slider body 1
Seat 12 is placed on wherein.Shrapnel 3 is then fixed on to the first fixed seat 11 and the second fixed seat 12 of slider body 1, shrapnel 3
Stop section 33 can just be stretched into the sliding slot 14 of slider body 1 by the purl hole 113 in the groove 111 of the first fixed seat 11, bullet
Groove 121 bottom of the one end abutted with cap 31 on the pulling-on piece touch part 32 of piece 3 by being seated at the second fixed seat 12, and shrapnel 3
Cap 31 be placed in the first fixed seat 11 and the top of the second fixed seat 12, wherein be set to the first fixed seat 11 and second
Cap fixed part 112 and 112 stress of cap fixed part at the top of fixed seat 12 and be in bending, and by cap 31 to being fixed
Riveted.The chain between cog that the insertion of stopper section 33 slide fastener is driven by pulling-on piece touch part 32, to prevent pull head from voluntarily being slided on slide fastener
It is dynamic, self-locking is played, when pull-up pulling-on piece 2 lifts stopper section 33, stopper section 33 lifts from the chain between cog of slide fastener, pull head
It smooth can slide.
The stopper section 33 of the shrapnel 3 of above-mentioned this kind of self-locked draught part is in flat, and with pull head, direction of travel is vertical on slide fastener
To being laterally that the touch part 32 and stopper section 33 of above-mentioned shrapnel 3 are lateral with direction that is longitudinally perpendicular and being generally aligned in the same plane prolongs
It stretches, since the stopper section 33 of embedded sprocket is by longitudinal force, especially in pull head misoperation, (such as pulling-on piece does not lift fully
And pull pull head), easily 32 relative deformation of opposite touch part of stopper section 33, stopper section 33 is gradually supportted relative to touch part 32
It opens, ultimately causes stopper section 33 and be difficult to steadily be embedded between the sprocket of slide fastener, pull head is caused to glide automatically.
In consideration of it, the present inventor carries out in-depth study to the above problem, there is this case generation then.
