Description

Zipper head combination structure improvement

The present invention relates to a zipper head, and more particularly to an improved zipper head combination structure that can be buckled on a zipper.

The general zipper basically sews two rows of sprocket on the opposite inner longitudinal edges of a pair of zipper tapes, and is provided with a slidable zipper head so that the two rows of sprocket can be engaged or disengaged to smoothly open and close the zipper. .

At present, the zipper head can be equipped with an elastic stopper, and the normal state card is set on the zipper. In the conventional zipper head structure, the zippering tab is mainly pivoted on the top of the zipper head main body, and the elastic fixing member is assembled, and the free portion of the fixing member is normally pressed against the cross bar of the pull tab to make the fixing member The fixed arm at one end normally passes through the top perforation of the main body of the zipper head to form a zipper on the card. When the pull tab is pulled upward, the stopper is moved upward by the crossbar to push the fixed arm upwards into the through hole, so that the zipper head can slide open the zipper.

The conventional zipper head is formed by die cutting of a metal sheet, which causes sharp edges on both sides of the fixed arm. When the clothes are in the washing process, the zipper head mounted on the laundry bag or the clothes will sway the pull tabs sharply, so that the crossbar of the pull tab frequently hits the sharp edges on both sides of the fixed arm, and the crossbar is easily separated. Damaged, causing the zipper head Laundry bags and clothing cannot be used anymore. Therefore, how to solve the above problems is the subject of research that the relevant industry players are eager to study.

The main purpose of the creation is that the zipper head has a convex stop at each end of the crossbar of the pull tab to improve the structural strength of the joint between the crossbar and the pull tab, and the crossbar is located in front of the fixed arm buckle state. The separation distance is formed to avoid the collision between the cross bar of the pull tab and the sharp edges on both sides of the fixed arm, thereby improving the service life of the slider and the pull tab.

In order to achieve the above object, the zipper head assembly structure of the present invention is improved, comprising a slider, a positioning member and a pull tab; the slider is provided with a passage for the zipper tooth row, and the front surface of the slider is spaced apart from the front positioning seat and the rear. Positioning the seat, and the slider is provided with a through hole communicating with the passage in the rear positioning seat; the positioning member has a positioning piece fixed on the front positioning seat and the rear positioning seat, and is bent downward at the front end of the positioning piece a rear extending elastic arm, and the end of the elastic arm is bent downward to have a fixed arm that passes through the perforation; the front end of the pull piece has a cross bar and a connected window, and the cross bar is pivotally connected to the front positioning seat and the rear positioning seat and the pulling Between the head surface and the elastic arm; characterized in that: the two ends of the cross bar of the pull tab extend toward the window to have a convex portion, and the elastic arm of the positioning member corresponds to the two convex portions of the cross bar, The window sleeve is placed around the rear positioning seat, and the two convex portions of the cross bar are rearwardly blocked on both sides of the rear positioning seat, and the cross bar is located in front of the fixed arm of the positioning member to form a separation distance.

The foregoing zipper head assembly structure is improved, wherein the positioning seat of the slider has opposite side plates on both sides, and the two convex portions of the cross bar are rearwardly blocked on the front edges of the two side plates.

The foregoing zipper head assembly structure is improved, wherein the two convex portions of the cross bar are separated The spacing is greater than the width of the elastic arm section.

For the purpose of achieving the above objectives, the technical means and its efficacy, the following is a description of the possible embodiments, and the following diagrams are described as follows: First, please refer to the first to fifth figures, which can be clearly seen from the figure. It can be seen that the zipper head assembly structure of the present invention is improved, including the slider 1, the positioning member 2 and the pull tab 3, wherein the slider 1 has a top body 11 and a bottom body 12 of opposite shapes, and is connected to the top body 11 a connecting body 13 between the front end of the bottom body 12 and a channel 14 for engaging a sprocket row (not shown) in the slider 1. The slider 1 is provided with a front positioning seat 15 and a rear portion on the surface of the top body 11. The positioning seat 16 is disposed, and the slider 1 is provided with a through hole 17 communicating with the passage 14 in the rear positioning seat 16, and the front positioning seat 15 and the rear positioning seat 16 each have opposite side plates 151, 161 and a positioning portion. 152, 162.

The positioning member 2 has a positioning piece 21 disposed on the front positioning seat 15, the rear positioning seat 16 and the positioning portions 152, 162, and is fixed by riveting, at the front end of the positioning piece 21 The lower end is bent with a resilient arm 22 extending rearward, and the end of the elastic arm 22 is bent downward with a fixed arm 23 and a blocking portion 231 which are pierced by the through hole 17.

The front end of the pull tab 3 has a cross bar 31 and a connecting window 32. The cross bar 31 of the pull tab 3 is pivotally connected between the front positioning seat 15 and the rear positioning seat 16 and the surface of the slider 1 and the elastic arm 22.

By the way, the slider 1, the positioning member 2 and the pull tab 3 are combined to form a zipper head, and the fixed arm 23 is normally inserted downward into the through hole 17 of the slider 1 and the passage 14 (refer to the fourth figure) to make the stop. The arm 23 is normally positioned and positioned on the zipper row. When the pull tab 3 is pulled upward (refer to the fifth figure), the elastic arm 22 of the positioning member 2 is moved up by the crossbar 31 to push the fixed arm 23 upwards into the through hole 17 to make the zipper. The head can slide to open the zipper.

The zipper head assembly structure of the present invention is improved in that the two ends of the cross bar 31 of the pull tab 3 extend rearwardly toward the window 32 with a convex portion 33, and the elastic arms 22 of the positioning member 2 correspond to the two convex portions of the cross bar 31. Between the blocking portions 33, the distance between the two convex portions 33 is larger than the width of the cross section of the elastic arm 22, and the window 32 of the pull tab 3 is sleeved around the rear positioning seat 16. Since the pull tab 3 has a convex portion 33 extending rearwardly at both ends of the cross bar 31, the structural strength of the connecting portion of the cross bar 31 and the pull tab 3 is relatively increased, and the two protruding portions 33 of the cross bar 31 are rearwardly blocked. The front edge of the side plates 161 of the rear positioning seat 16 is disposed such that the cross bar 31 is located at a front side of the locking arm 23 of the positioning member 2 to form a separation distance to avoid the two sides of the cross bar 31 and the fixed arm 23 of the pull tab 3. The sharp edges 232 collide with each other to cause damage, thereby enhancing the service life of the slider and the pull tab 3.

The above embodiments are only used to facilitate the description of the present invention, and are not intended to be limiting. All kinds of simple changes and modifications that can be made by those skilled in the art without departing from the spirit of this creation should still be included in the scope of the following patent application.
