Description

Improvement of the cap structure of the zipper head

The present invention relates to a cap structure, in particular to a cap structure in which a shrapnel is first placed in a cap and mounted on a zipper head.

The conventional zipper head structure includes a slider, a pull tab, a spring clip and a cap. The zipper head is engaged with a zipper, and the slider has a horse hook therein. When the pull tab on the slider is pulled, the pull tab drags the horse hook in the slider, and the zipper head is further unlocked on the zipper. Free to pull. When the pull tab is not pulled, the hook is pressed back to the locked position by the elastic force of the elastic piece to lock the zipper, so that the slider does not slip freely.

Referring to Fig. 1, the old zipper head (not shown) will be subjected to the lacquering step after the assembly is completed. Often, when the zipper head is painted, a processed lacquer layer 101a is formed in the cap 1a, resulting in a zipper head. The inside is blocked by the excess lacquer layer 101a, and after the elastic piece 201a covers the lacquer layer 101a, the width of the elastic piece 201a is increased, except that the cap 1a is caught, when the pull piece drags the slider, It is often more laborious.

When the zipper head is subjected to the varnish processing, the lacquer layer 101a is caused to block the inside of the zipper head. In the past, the appearance of the cap 1a was changed, and the side walls of the cap 1a were outwardly curved so that the inside of the cap 1a was formed. A larger accommodating space can accommodate the excess lacquer layer 101a, but this affects the structural strength of the cap 1a, and the manufacturing process easily causes the cap 1a to be bent and deformed.

The two ends of the elastic piece 2 are respectively provided with an opening 21, and a recess 22 is respectively disposed on opposite sides of the central portion of the end surface of the elastic piece 2. The two openings 21 can respectively penetrate the two ends of the elastic piece 2 in opposite directions. In this way, the two openings 21 are disposed in the open state of the elastic piece 2, and the direction of opening thereof is not limited. In the embodiment, the two openings 21 are connected to each other along the longitudinal direction of the elastic piece 2. Outside the shrapnel 2.

The two side walls 15 are respectively provided with a locking portion 17 , and the locking portion 17 is disposed beside the opening 16 . The two latching portions 17 are respectively formed by bending the corresponding side walls 15 toward the accommodating space 12, and the two latching portions 17 are arranged diagonally opposite. The elastic piece 2 is in contact with the two locking portions 17 , and the locking portion 17 can be used to prevent the elastic piece 2 from falling outside the cap 1 when the zipper head is pulled.

Referring to FIG. 3 to FIG. 4 , the elastic piece 2 is assembled in the accommodating space 12 , and both ends of the elastic piece 2 abut against the abutting portion 13 of the cap 1 . The two corners of the notch 22 in the middle of the elastic piece 2 are curved. The elastic piece 2 is bent in a V shape to form a curved end 23 on the top surface of the elastic piece 2. The curved end 23 of the elastic piece 2 is in contact with the hook of a slider (not shown).

Referring to FIG. 3 and FIG. 5, when the zipper head is pulled, the horse hook will loosen and abut against the curved end 23 of the elastic piece 2, and the curved end 23 will be deformed toward the concave portion 14 of the cap 1, The accommodating space 12 is pressed down by an appropriate displacement. When the zipper head is assembled, the elastic piece 2 of the present invention is first mounted on the cap 1 as an assembly, and the pull tab (not shown) is placed on the opening 16 of the two side walls 15, and finally the assembly is mounted thereon.
