The specific embodiment
Embodiment of the present utility model is as shown in Fig. 1 to 11, the body that wherein Fig. 1 is pull head, it comprises front end is wide, rear end is narrow upper flange 1 and lower wing plate 2, upper flange 1 is with lower wing plate 2 positioned opposite and be connected by column, this column is located at the front end of upper flange 1 and lower wing plate 2, so that be separated out two slide fastener passages between upper flange 1 and lower wing plate 2; And upper flange 1 both sides of the edge, rear end have the flange towards lower wing plate, lower wing plate 2 both sides of the edge, rear end have the flange towards upper flange, the flange of upper flange 1 and lower wing plate 2 is mutually close, just allows zipper cloth belt pass through gap so that upper flange 1 and lower wing plate 2 both sides, rear end form; Described upper flange 1 is held backward and is provided with successively installing hole 3, erecting bed 4, positioning table 5, installing port 6 and spacing beam 7 from front end; The position of described installing hole 3 is corresponding with the position of column, so that installing hole 3 extends to column inside; Described erecting bed 4 tops are an arc-shaped transitional surface, and erecting bed 4 is provided with the axis hole that connects its both sides; Described positioning table 5 is inclined-plane towards a side of erecting bed 4, and should stay a determining deviation between positioning table 5 and erecting bed 4, to pulling-on piece 9 is arranged between positioning table 5 and erecting bed 4; Described upper flange 1 rear end hollow out is to form installing port 6; Described spacing beam 7 is located at the other end of installing port 6 with respect to positioning table 5, this spacing beam 7 to form arch bridge shape, form groove position, and spacing beam 7 both sides is inclined-plane toward projection with the bottom surface that makes spacing beam 7.
Fig. 2 is the structural representation before cap 8 assemblings, from this figure, the end face hollow out of described cap 8 front ends, the both sides inwall of this end face hollow part is provided with a countershaft 81, and the both sides inwall of this end face hollow part is outwardly-bent so that two rotating shaft 81 spacing are greater than the width of erecting bed 4, be convenient to the installation of cap 8, and the rear end of cap 8 is extruded with limited block 82 toward its length direction; Fig. 3 is the structural representation after cap 8 assembling, from this figure, now the both sides inwall of cap 8 end face hollow parts by external force toward interior pressing, so that two rotating shafts 81 embed in the axis hole of erecting bed 4; Fig. 4 is the bottom surface structure schematic diagram of cap 8, and the two side of described cap 8 rear ends is equipped with a lock point 83, and the tip of lock point 83 is through installing port 6 towards lower wing plate 2, and lock point 83 dislocation on cap 8 two sides, rear end are arranged.
Fig. 5 is helical compression spring 31, and this helical compression spring 31 is arranged in installing hole 3, and cap 8 is withstood in the upper end of helical compression spring 31.
Fig. 6 and Fig. 7 are the common structure schematic diagram of pulling-on piece 9, and the beam position of the pulling-on piece 9 shown in Fig. 6 has opening, and the sealing of the beam position of the pulling-on piece 9 shown in Fig. 7, two kinds of pulling-on pieces 9 all can be applicable on pull head of the present utility model.
In the time that pull head is assembled, can carry out according to the following steps:
1, helical compression spring 31 is placed in installing hole 3;
2, pulling-on piece 9 is placed between positioning table 5 and erecting bed 4, shifts to installing port 6 because positioning table 5 limits pulling-on piece 9, thereby realized the positioning action of pull-tab 9;
3, the rotating shaft on cap 8 81 is aimed to erecting bed 4 upper shaft holes, and make limited block 82 be placed in spacing beam 7 belows through installing port 6;
4, by the both sides inwall of cap 8 end face hollow parts toward interior pressing, so that two rotating shafts 81 embed in the axis hole of erecting bed 4.
Structure after assembling specifically as shown in FIG. 8 and 9, in the time that pulling-on piece 9 draws toward cap 8 front end, pulling-on piece 9 keeps separating with cap 8 front ends, in the time that pulling-on piece 9 draws toward cap 8 rear end, pulling-on piece 9 keeps separating with cap 8, spacing beam 7, thereby it is smooth and easy that pulling-on piece 9 is pulled, and from Figure 10 and 11, in the situation that pull head is not subject to external force, the applied thrust of helical compression spring 31 to cap 8, cap 8 is rotated counterclockwise around erecting bed 4, and now limited block 82 separates with spacing beam 7, and lock point 83 presses toward lower wing plate 2 directions; In the time that above-mentioned pull head and slide fastener are used in conjunction with, because lock point 83 can press toward lower wing plate 2 directions, so lock point 83 now will embed in the gap of slide fastener coupling element, make the pull head can locking zipper under can nature, and cap 8 both sides are equipped with lock point 83, can lock slide fastener both sides, its lock power is stronger than existing monolock point pull head simultaneously; In the time that needs pull pull head, as long as pull pulling-on piece 9, pulling-on piece 9 clockwise rotates drive cap 8 around erecting bed 4, until limited block 82 and spacing beam 7 butts, now lock point 83 no longer contacts with slide fastener coupling element, not only removes the locking to slide fastener, also avoids lock point to cause wearing and tearing to slide fastener coupling element surface.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also change and revise above-mentioned embodiment.Therefore, the utility model is not limited to the specific embodiment disclosed and described above, also should fall in the protection domain of claim of the present utility model modifications and changes more of the present utility model.In addition,, although used some specific terms in this description, these terms just for convenience of description, do not form any restriction to the utility model.
