Please refer to Fig. 1 and Fig. 2, this trunk 18, in strip bending structure, for being connected with the pull bar 22 (as shown in Figure 3) of a pulling-on piece 20, drives this puller slide block 10 to move under the traction of this pulling-on piece 20.This trunk 18 comprises the parallel portion 184 in the middle part of being arranged on, is connected to the connecting portion 182 of one end of this parallel portion 184 and is connected to the stop section 186 of this parallel portion 184 other end.This connecting portion 182 to be integrally connected on upper flange 16 and substantially vertical with this upper flange 16, this parallel portion 184 this connecting portion 182 relative at right angles bending and direction bending along this upper flange 16 parallel extends, this stop section 186 this parallel portion 184 relative vertically bends setting towards this upper flange 16, make to form a passage between the end of this stop section 186 and this upper flange 16, the width of this passage is greater than the external diameter (as shown in Figure 2) of this pull bar 22.
Please refer to Fig. 1 and Fig. 2, this upper flange 16 is integrally formed with a limited block 11, in the passage of this limited block 11 between this stop section 186 and this upper flange 16, namely immediately below this stop section 186 (as shown in Figure 2).The kink 112 that this limited block 11 comprises a seat body 114 and is arranged on above this seat body 114, the width of this kink 112 is less than the width of this seat body 114.This kink 112 is to arranging stop section 186, the direction that this kink 112 extends along this parallel portion 184 is obliquely installed towards the direction away from this parallel portion 184, with this angle of stop section 186 in an acute angle, and the gap 13 that this stop section 186 relative to this stop section 186 gap-forming one tilts.The direction that outside bottom this stop section 186 extends relative to this kink 112 is parallel is provided with a chamfering 181, and this chamfering 181 is for expanding this gap 13.
Please refer to Fig. 3 and Fig. 4, when assembling pulling-on piece 20 to this puller slide block 10, first this puller slide block 10 is fixed in an assembly or fitting table (not shown); Then, the pull bar 22 of pulling-on piece 20 is set on this trunk 18 through this gap 13, and makes this pulling-on piece 20 away from this stop section 186; In this step, it should be noted that because this gap 13 is that this stop section 186 tilts relatively, as long as the external diameter of this pull bar 22 of width treatment in this gap 13, this pull bar 22 can be made through this gap 13, thus this pulling-on piece 20 is set on this trunk 18.Finally, utilize the kink 112 of a punching mechanism (not shown) this limited block 11 of punching press on the direction towards this parallel portion 184, this kink 112 is made deformation to occur to be folded into the position (as shown in Figure 4) almost parallel with this stop section 186, thus reduce the width in the gap 13 between this limited block 11 and this stop section 186, the width in this gap 13 is made to be less than the external diameter of the pull bar 22 of this pulling-on piece 20, thus make the pull bar 22 of this pulling-on piece 20 can not from this trunk 18 and this upper flange 16, deviate from the space that limited block 11 surrounds, complete the assembling of this pulling-on piece 20.
In sum, this puller slide block 10 is by arranging this trunk 18 and this limited block 11, the gap 13 that gap-forming this stop section 186 relative tilts between the kink 112 and the stop section 186 of this trunk 18 of this limited block 11, reduces this gap fixedly can be assembled into pulling-on piece 20 in this puller slide block 10 by bending this kink 112.Compared with prior art, this trunk 18 itself does not receive any damage in an assembling process, therefore can keep higher intensity, has the advantage that sound construction is durable.The bending although the kink 112 of this limited block 11 is stamped, but, in this puller slide block 10 course of work, the pull bar 22 of this pulling-on piece 20 does not apply pulling force to this limited block 11 substantially, this pull bar 22 only needs the position pulling this parallel portion 184 to be connected with this connecting portion 182, or the position that this parallel portion 184 is connected with this stop section 186 just can drive this puller slide block 10 to move forward or backward along chain band.So this limited block 11 can not be directly stressed, under it only needs to stop relaxed state, this pull bar 22 does not get loose from this puller slide block 10.Like this, just can ensure that integrally-built sound construction is durable.
Understandable, this seat body 114 arranges not necessarily, and its existence is the height in order to reduce this kink 112, does not arrange also passable.The direction of this kink 112 bending also need not be parallel to the direction of this parallel portion 184 extension, also passable to the bending of other direction, as long as the gap 13 of this inclination can be formed with this stop section 186, and bend this kink 112 by punching press and reduce this gap 13, can guarantee that this puller slide block 10 normally works.
Please refer to Fig. 3 and Fig. 4, the pull head of first embodiment of the invention comprises this puller slide block 10 and pulling-on piece 20.This pulling-on piece 20 is set on the trunk 18 of this puller slide block 10.During use, the pull bar 22 of this pulling-on piece 20 moves along this parallel portion 184, drives this puller slide block 10 to move forward and backward.
Please refer to Fig. 5, its depicted is the puller slide block 10a of second embodiment of the invention, the difference of the puller slide block 10 of this puller slide block 10a and first embodiment of the invention is, the bottom surface of the stop section 186 of this trunk 18a protrudes out downwards and is provided with block 1862, and this kink 112a is to being provided with slot to make way 1121 by block 1862.When this kink 112a is folded into the direction parallel with this stop section 186, this slot to make way 1121 just in time can accommodate this block 1862.By arranging this block 1862 and this slot to make way 1121, gap after can making punching press between this kink 112a and this stop section 186 becomes the broken line (as shown in Figure 5) that convex-concave rises and falls, and this just can effectively prevent pieces of cloth from entering the situation of this gap generation locking.
