Abstract
The present invention provides a zipper head assembly structure. The zipper head assembly structure includes a sliding member, an elastic member and a retaining member. The sliding member has a base portion, a first lateral wall portion, a second lateral wall portion and a seat portion. The base portion has at least one retaining block. The retaining block has an inner surface inclined at an adjustable angle relative to an inner surface of the base portion. The retaining member has a positioning portion disposed on an end thereof and a retaining body disposed on another end thereof. Therefore, the retaining portion can be restricted by the bottom side surface of the at least one retaining block and can be movably retained on a predetermined plane without being changed by a change of the adjustable angle.
Claims17
A zipper head assembly structure, comprising:
- a sliding assembly including a sliding member, an elastic member and a retaining member, the sliding member having a base portion, a first lateral wall portion, a second lateral wall portion and a seat portion, wherein the first lateral wall portion and the second lateral wall portion extend respectively upwardly from two opposite lateral sides of the base portion, the first lateral wall portion and the second lateral wall portion correspond to each other and are connected to a front side portion of the base portion, the seat portion is disposed on the base portion and is connected to a rear side portion of the base portion, the seat portion has a positioning through hole formed between the first lateral wall portion and the second lateral wall portion, and the elastic member is disposed on the seat portion to elastically abut against the retaining member;
- and
- a pulling member movably mated with the retaining member;
- wherein the seat portion has at least one retaining block and at least one through opening adjacent to the at least one retaining block, the at least one retaining block has an inner surface extending inwardly from an inner surface of the seat portion, the inner surface of the at least one retaining block is inclined at an adjustable angle relative to the inner surface of the seat portion, and the at least one retaining block has a top side surface, a bottom side surface opposite to the top side surface, and a front surface connected between the top side surface and the bottom side surface;
- wherein the retaining member has a positioning portion disposed on an end thereof for passing through the positioning through hole, the retaining member has a retaining portion disposed on another end thereof, and the retaining portion is restricted by the bottom side surface of the at least one retaining block and is movably retained on a predetermined plane without being changed by a change of the adjustable angle;
- wherein the elastic member has a fixing portion fixed on the seat portion, and a thickness of the elastic portion is smaller than a thickness of the fixing portion.
