- Referring to
FIG. 1 toFIG. 6 , the first embodiment of the present disclosure provides a zipper head assembly structure Z, including: a sliding member 1 (or a sliding head), a pull tab 2 (or a pull piece), a locking hook 3 (or a horse-like hook), acap body 4 and an elastic piece 5 (or a flat spring), and thecap body 4 and theelastic piece 5 can be combined with each other to form a cap structure S. - Firstly, referring to
FIG. 1 toFIG. 3 , the slidingmember 1 has a first retainingseat 11 and a second retainingseat 12. The first retainingseat 11 has a hook groove 100 shown as a blind hole, and the second retainingseat 12 has ahook hole 120 shown as a through hole. Thepull tab 2 has anend portion 20 disposed inside a receivingspace 13 formed between the first retainingseat 11 and the second retainingseat 12. Thelocking hook 3 is disposed on the slidingmember 1, and thelocking hook 3 has afirst end portion 31 disposed inside thehook groove 110 and asecond end portion 32 opposite to thefirst end portion 31 and passing through thehook hole 120 to form a stop portion. Thecap body 4 has two opposite end portions (41, 42) respectively disposed on the first retainingseat 11 and the second retainingseat 12, theelastic piece 5 is disposed between theinner surface 400 of thecap body 4 and thelocking hook 3 and abutted against the lockinghook 3, and both thelocking hook 3 and theelastic piece 5 are disposed between the slidingmember 1 and the cap body 4 (as shown inFIG. 2 andFIG. 3 ). - Moreover, referring to
FIG. 4 toFIG. 6 , thecap body 4 has at least two first innerconcave grooves 40A corresponding to each other, at least two first retaining blocks 41A corresponding to each other and respectively extending outwardly from the two first innerconcave grooves 40A, and at least two first throughholes 42A corresponding to each other and respectively adjacent to the two first retaining blocks 41A. The two first retaining blocks 41A can contact theelastic piece 5 for retaining or abutting the elastic piece 5 (i.e., theelastic piece 5 can be retained inside thecap body 4 through the twofirst retaining blocks 41A). In addition, thecap body 4 has aninner surface 400, anouter surface 401 and abottom surface 402 connected between theinner surface 400 and theouter surface 401, the two first innerconcave grooves 40A are disposed on theinner surface 400 of thecap body 4, and the two first throughholes 42A pass through thecap body 4 to form two breach holes between theinner surface 400 and theouter surface 401 of the cap body 4 (for example, the twobreach holes 42A are formed by dotting or punching thecap body 4 from theouter surface 401 to the inner surface 400). Therefore, the two first innerconcave grooves 40A can be formed on theinner surface 400 of thecap body 4 in advance, so that the thickness between theinner surface 400 and theouter surface 401 of thecap body 4 can be decreased or thinned (that is to say, the thickness of the material of thecap body 4 can be decreased or thinned), and thus it is easy to concurrently form the first throughhole 42A and thefirst retaining block 41A by a dotting or punching machine. - More particularly, referring to
FIG. 5 , the two first innerconcave grooves 40A can be diagonally disposed on theinner surface 400 of thecap body 4, and the two first innerconcave grooves 40A are respectively adjacent to two opposite end sides (4011, 4012) of thecap body 4. The two first retaining blocks 41A can be respectively and diagonally disposed on the two first innerconcave grooves 40A, and the two first retaining blocks 41A are respectively adjacent to the two opposite end sides (4011, 4012) of thecap body 4. The two first throughholes 42A can be diagonally disposed on theouter surface 401 of thecap body 4, and the two first throughholes 42A are respectively adjacent to the two opposite end sides (4011, 4012) of thecap body 4. In other words, the two first innerconcave grooves 40A and the two first retaining blocks 41A are disposed on the long lateral side of theinner surface 400 of thecap body 4, and the two first throughholes 42A are disposed on the long lateral side of theouter surface 401 of thecap body 4. Therefore, the position of the first innerconcave groove 40A, thefirst retaining block 41A, or the first throughhole 42A is rotated relative to the end side (4011 or 4012) of thecap body 4 by 90 degrees. - For example, referring to
FIG. 4 , each first innerconcave groove 40A has afirst end 401A connected to thebottom surface 402 of thecap body 4 and asecond end 402A opposite to thefirst end 401A and far away from thebottom surface 402 of thecap body 4, and the width W of the first innerconcave groove 40A is narrowed gradually from thefirst end 401A to thesecond end 402A of the first innerconcave groove 40A. However, the above-mentioned design for the first innerconcave groove 40A of the first embodiment is merely an example and is not meant to limit the present disclosure. In addition, referring toFIG. 5 andFIG. 6 , eachfirst retaining block 41A is adjacent to thesecond end 402A of the corresponding first innerconcave groove 40A, and each first throughhole 42A is adjacent to thesecond end 402A of the corresponding first innerconcave groove 40A. - Referring to
FIG. 4 toFIG. 6 , it should be noted that each of thefirst retaining blocks 41A (i.e., the retaining block) has aninner surface 410A extending inwardly from theinner surface 400 of the cap body 4 (that is to say, theinner surface 410A extends along a long axle of thecap body 4, not along a short axle of the cap body 4), and theinner surface 410A of thefirst retaining block 41A is inclined at a first adjustable angle θ1 (i.e., an adjustable angle) relative to theinner surface 400 of thecap body 4. In addition, each of thefirst retaining blocks 41A has a firsttop side surface 411A, a firstbottom side surface 412A opposite to the firsttop side surface 411A, and a firstfront surface 413A connected between the firsttop side surface 411A and the firstbottom side surface 412A. Moreover, theelastic piece 5 is supported by the two firsttop side surfaces 411A of the at least two first retaining blocks 41A so as to hold theelastic piece 5 on a predetermined plane P without being changed by a change of the first adjustable angle θ1. That is to say, no matter how the first adjustable angle θ1 is adjusted or changed, theelastic piece 5 can be supported by the two firsttop side surfaces 411A so as to keep theelastic piece 5 on the predetermined plane P, so that theelastic piece 5 cannot be inclined when the first adjustable angle θ1 is adjusted or changed. - For example, referring to
FIG. 7 andFIG. 8 , the present disclosure provides a first mold M1 including a first processing tool M10, and a second mold M2 including a second processing tool M20. The first processing tool M10 and the second processing tool M20 can be respectively inserted into two lateral sides of acap body 4′, so that the at least two first retaining blocks 41A can be formed by punching. - Referring to
FIG. 5 andFIG. 9 , it should be noted that the extending direction of each of the at least two first retaining blocks 41A can be changed according to different requirements, but no matter how the extending direction of each of the at least twofirst retaining blocks 41A is changed, theelastic piece 5 can be supported by the two firsttop side surfaces 411A so as to keep theelastic piece 5 on the predetermined plane P, so that theelastic piece 5 cannot be inclined when the extending direction of each of the at least twofirst retaining blocks 41A is changed. - Referring to
FIG. 10 toFIG. 12 , the second embodiment of the present disclosure provides a zipper head assembly structure Z, and thecap body 4 and theelastic piece 5 can be combined with each other to form a cap structure S. ComparingFIGS. 4 ˜6 withFIGS. 10 ˜12, the difference between the second embodiment and the first embodiment is as follows: in the second embodiment, referring toFIG. 10 toFIG. 12 , thecap body 4 has at least two second innerconcave grooves 40B corresponding to each other, at least two second retaining blocks 41B corresponding to each other and respectively extending outwardly from the two second innerconcave grooves 40B, and at least two second throughholes 42B corresponding to each other and respectively adjacent to the two second retaining blocks 41B. In addition, the two second innerconcave grooves 40B are disposed on theinner surface 400 of thecap body 4, the two second throughholes 42B pass through thecap body 4 to form another two breach holes between theinner surface 400 and theouter surface 401 of the cap body 4 (for example, another twobreach holes 42A are formed by dotting or punching thecap body 4 from theouter surface 401 to the inner surface 400), and the two second retaining blocks 41B contact theelastic piece 5 for retaining or abutting theelastic piece 5. Therefore, the two second innerconcave grooves 40B can be formed on theinner surface 400 of thecap body 4 in advance, so that the thickness between theinner surface 400 and theouter surface 401 of thecap body 4 can be decreased or thinned, and thus it is easy to concurrently form the second throughhole 42B and thesecond retaining block 41B by a dotting or punching machine. - More particularly, referring to
FIG. 11 , the two second innerconcave grooves 40B can be diagonally disposed on theinner surface 400 of thecap body 4, and the two second innerconcave grooves 40B are respectively adjacent to two opposite end sides (4011, 4012) of thecap body 4. The two second retaining blocks 41B can be respectively and diagonally disposed on the two second innerconcave grooves 40B, and the two second retaining blocks 41B are respectively adjacent to the two opposite end sides (4011, 4012) of thecap body 4. The two second throughholes 42B can be diagonally disposed on theouter surface 401 of thecap body 4, and the two second throughholes 42B are respectively adjacent to the two opposite end sides (4011, 4012) of thecap body 4. In other words, the two second innerconcave grooves 40B and the two second retaining blocks 41B are disposed on the long lateral side of theinner surface 400 of thecap body 4, and the two second throughholes 42B are disposed on the long lateral side of theouter surface 401 of thecap body 4. Therefore, the position of the second innerconcave groove 40B, thesecond retaining block 41B, or the second throughhole 42B is rotated relative to the end side (4011 or 4012) of thecap body 4 by 90 degrees. - For example, referring to
FIG. 4 andFIG. 10 , each second innerconcave groove 40B has asecond end 401B connected to thebottom surface 40B of thecap body 4 and asecond end 402B opposite to thesecond end 401B and far away from thebottom surface 402 of thecap body 4, and the width (no label) of the second innerconcave groove 40B is narrowed gradually from thesecond end 401B to thesecond end 402B of the second innerconcave groove 40B. However, the above-mentioned design for the second innerconcave groove 40B of the second embodiment is merely an example and is not meant to limit the present disclosure. - More particularly, referring to
FIG. 5 ,FIG. 6 ,FIG. 11 andFIG. 12 , eachsecond retaining block 41B is adjacent to thesecond end 402B of the corresponding second innerconcave groove 40B, and each second throughhole 42B is adjacent to thesecond end 402B of the corresponding second innerconcave groove 40B. - Referring to
FIG. 10 toFIG. 12 , it should be noted that each of the second retaining blocks 41B (i.e., the retaining block) has aninner surface 410B extending inwardly from theinner surface 400 of the cap body 4 (that is to say, theinner surface 410B extends along a long axle of thecap body 4, not along a short axle of the cap body 4), and theinner surface 410B of thesecond retaining block 41B is inclined at a second adjustable angle θ2 (i.e., an adjustable angle) relative to theinner surface 400 of thecap body 4. In addition, each of the second retaining blocks 41B has a secondtop side surface 411B, a secondbottom side surface 412B opposite to the secondtop side surface 411B, and a secondfront surface 413B connected between the secondtop side surface 411B and the secondbottom side surface 412B. Moreover, theelastic piece 5 is supported by the two second top side surfaces 411B of the at least two second retaining blocks 41B so as to hold theelastic piece 5 on a predetermined plane P without being changed by a change of the second adjustable angle θ2. That is to say, no matter how the second adjustable angle θ2 is adjusted or changed, theelastic piece 5 can be supported by the two second top side surfaces 411B so as to keep theelastic piece 5 on the predetermined plane P, so that theelastic piece 5 cannot be inclined when the second adjustable angle θ2 is adjusted or changed. - Referring to
FIG. 11 andFIG. 13 , it should be noted that the extending direction of each of the at least two second retaining blocks 41B can be changed according to different requirements, but no matter how the extending direction of each of the at least two second retaining blocks 41B is changed, theelastic piece 5 can be supported by the two second top side surfaces 411B so as to keep theelastic piece 5 on the predetermined plane P, so that theelastic piece 5 cannot be inclined when the extending direction of each of the at least two second retaining blocks 41B is changed - In conclusion, by matching the features of “the inner surface (410A or 410B) of the retaining block (41A or 41B) being inclined at an adjustable angle (θ1 or θ2) relative to the
inner surface 400 of thecap body 4” and “theelastic piece 5 being supported by the at least two retaining blocks (41A or 41B) so as to hold theelastic piece 5 on a predetermined plane P”, theelastic piece 5 can be held on the predetermined plane P without being changed by a change of the adjustable angle (θ1 or θ2). - More particularly, the two second inner
concave grooves 40A can be formed on theinner surface 400 of thecap body 4 by a die casting process and the two first retaining blocks 41A and the two first throughholes 42A can be concurrently formed by a dotting or punching machine, so that when theelastic piece 5 is disposed on the inner surface 100 of thecap body 4, the two first retaining blocks 41A can contact theelastic piece 5 for retaining or abutting theelastic piece 5, so that the production efficiency of manufacturing the cap structure S and the robustness of retaining theelastic piece 5 by the two first retaining blocks 41A can be increased. - The aforementioned descriptions merely represent the preferred embodiments of the present disclosure, without any intention to limit the scope of the present disclosure which is fully described only within the following claims. Various equivalent changes, alterations or modifications based on the claims of the present disclosure are all, consequently, viewed as being embraced by the scope of the present disclosure.
