CAP STRUCTURE AND ZIPPER HEAD ASSEMBLY STRUCTURE
A cap structure includes a cap body and an elastic piece. The cap body has at least two first inner concave grooves corresponding to each other, at least two first retaining blocks respectively extending outwardly from the at least two first inner concave grooves, and at least two first through holes corresponding to each other and respectively adjacent to the at least two first retaining blocks. The at least two first inner concave grooves are disposed on the inner surface of the cap body, and the at least two first through holes pass through the cap body to form two breach holes between the inner and the outer surfaces of the cap body. The elastic piece is disposed on the inner surface of the cap body, and the at least two first retaining blocks contact the elastic piece for retaining or abutting the elastic piece.
The present disclosure relates to a cap structure and a zipper head assembly structure, and more particularly to a cap structure and a zipper head assembly structure.
BACKGROUND OF THE INVENTIONIn general, zippers are basic elements in clothing or accessories. Compared to buttons, the zippers are easier to use. A conventional zipper comprises a zipper head and a tape. The zipper head works with the tape to allow the pulling action. Recently, the zipper has been used commonly for clothing, pants, backpack, and other accessories.
A conventional zipper head assembly structure includes a fastening slider, a pulling piece, a horse-like hook and a cap. The above components of the conventional zipper head assembly structure are assembled in the following procedure. One end portion of the pulling piece is positioned into a recessed space of the fastening slider. The pulling piece is pushed toward one end of the fastening slider, so that a first fixing base or a second fixing base of the fastening slider can be put around a hole of the pulling piece. Then, the horse-like hook is fixed to the first fixing base and the second fixing base of the fastening slider. The head portion of the horse-like hook is positioned in a groove of the first fixing base, while the tail portion of the horse-like hook is positioned to abut against the bottom of the groove of the second fixing base. The abdominal portion of the horse-like hook is supported on the end portion of the pulling piece. The stop portion of the horse-like hook extends into a sliding groove of the fastening slider via a horse-like hook hole between the first fixing base and the second fixing base. Finally, the cap is used to cover on the first fixing base and the second fixing base of the fastening slider. An elastic piece is inserted into the interior of the cap for abutting on the horse-like hook.
