Finally, the cap is closed on the first fixed seat and the second fixed seat of the slider, wherein a spring piece is clamped in the cap, and the spring piece presses against the horse hook. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a zipper head assembly structure and a cap structure and a method for manufacturing the cap structure in view of the deficiencies in the prior art.

[0005] In order to solve the above technical problems, one of the technical solutions adopted by the present invention is to provide a cap structure.

The spring is arranged on the inner surface of the cap body, and at least two of the fixing protrusions contact the spring so that the spring is fixed by at least two of the fixing protrusions. Wherein, the inner surface of each of the fixing protrusions extends inward from the inner surface of the cap body, and the inner surface of each of the fixing protrusions is inclined at an adjustable angle relative to the inner surface of the cap body. Each of the fastening protrusions has an upper end face, a lower end face arranged opposite to the upper end face, and a front end face connected between the upper end face and the lower end face, and the spring sheet is supported by the two upper end faces of at least two of the fastening protrusions to be maintained on a predetermined plane. The first fixing seat has a hook groove, and the second fixing seat has a hook hole. A vertical projection of one of the fastening protrusions projected onto the first fixing seat will not be projected onto the hook groove, and a vertical projection of another of the fastening protrusions projected onto the second fixing seat will not be projected onto the hook hole.

[0009] In order to solve the above technical problems, another technical solution adopted by the present invention is to provide a method for making a cap structure. The method for making the cap structure includes: placing a spring sheet into an initial cap body; inserting a first processing tool of a first mold and a second processing tool of a second mold into two opposite long sides of the initial cap body respectively to form a cap body with two fixing protrusions; and removing the first mold and the second mold. Wherein, the cap body has two fixing protrusions corresponding to each other and two through openings corresponding to each other and respectively adjacent to the two fixing protrusions. Wherein, the cap body has an inner surface, an outer surface and a lower surface connected between the inner surface and the outer surface of the cap body, and the two through openings penetrate the cap body to form two hole features between the inner surface and the outer surface of the cap body. Wherein, the two fixing protrusions contact the spring sheet so that the spring sheet is fixed by the two fixing protrusions. Wherein, the inner surface of each of the fixing protrusions extends inward from the inner surface of the cap body, and the inner surface of each of the fixing protrusions is inclined at an adjustable angle relative to the inner surface of the cap body. Wherein, each of the fixing protrusions has an upper end face, a lower end face arranged opposite to the upper end face, and a front end face connected between the upper end face and the lower end face, and the spring sheet is supported by the two upper end faces of the two fixing protrusions to maintain on a predetermined plane. Wherein, the first mold has a first carrier for carrying the first machining tool, and the second mold has a second carrier for carrying the second machining tool. Wherein, in the step of inserting the first machining tool of the first mold and the second machining tool of the second mold into the two opposite long sides of the initial cap body, the first carrier of the first mold and the second carrier of the second mold will not contact the two opposite long sides of the initial cap body.

[0010] Preferably, when the two opposite end portions of the cap body are respectively arranged on a first fixing seat and a second fixing seat of a sliding body, a vertical projection of one of the fixing protrusions projected onto the first fixing seat will not be projected onto a hook groove of the first fixing seat, and a vertical projection of another of the fixing protrusions projected onto the second fixing seat will not be projected onto a hook hole of the second fixing seat.

[0011] In order to solve the above technical problems, another technical solution adopted by the present invention is to provide a zipper head assembly structure, wherein the zipper head assembly structure includes a sliding body, a pull plate, a lock hook, a cap body and a spring. The sliding body has a first fixed seat and a second fixed seat, the first fixed seat has a hook groove, and the second fixed seat has a hook hole. An end portion of the pull plate is arranged between the first fixed seat and the second fixed seat. The lock hook is arranged on the sliding body, and the lock hook has a first end portion arranged in the hook groove and a second end portion passing through the hook hole. The two opposite end portions of the cap body are respectively arranged on the first fixing seat and the second fixing seat, the cap body has at least two fixing protrusions corresponding to each other and at least two through openings corresponding to each other and respectively adjacent to the at least two fixing protrusions, the cap body has an inner surface, an outer surface and a lower surface connected between the inner surface and the outer surface of the cap body, and at least two through openings penetrate the cap body to form two hole features between the inner surface and the outer surface of the cap body. The spring sheet is arranged between the inner surface of the cap body and the locking hook and abuts against the locking hook, and at least two fixing protrusions contact the spring sheet so that the spring sheet is fixed by the at least two fixing protrusions. Wherein, the inner surface of each fixing protrusion extends inward from the inner surface of the cap body, and the inner surface of each fixing protrusion is inclined at an adjustable angle relative to the inner surface of the cap body. Each of the fastening protrusions has an upper end face, a lower end face arranged opposite to the upper end face, and a front end face connected between the upper end face and the lower end face, and the spring sheet is supported by the two upper end faces of at least two of the fastening protrusions to be maintained on a predetermined plane. A vertical projection of one of the fastening protrusions projected onto the first fixing seat will not be projected onto the hook groove of the first fixing seat, and a vertical projection of another of the fastening protrusions projected onto the second fixing seat will not be projected onto the hook hole of the second fixing seat.

[0012] Preferably, the two inner surfaces of at least two of the fixing protrusions are arranged face to face with each other, and the vertical projection of the inner surface of each of the fixing protrusions onto the inner surface of the cap body will not fall on the locking hook.

[0013] One of the beneficial effects of the present invention is that the zipper head combination structure, the cap structure and the method for manufacturing the cap structure provided by the present invention can achieve the technical solutions of "the inner surface of each of the fixing protrusions is inclined at an adjustable angle relative to the inner surface of the cap body" and "the spring sheet is supported by each of the fixing protrusions to be maintained on a predetermined plane" so that the spring sheet can be maintained on the predetermined plane without changing due to changes in the adjustable angle.

[0014] In one of the feasible embodiments, a vertical projection of one of the fastening protrusions projected onto the first fixing seat will not be projected onto the hook groove, and a vertical projection of the other fastening protrusion projected onto the second fixing seat will not be projected onto the hook hole. In other words, the two fastening protrusions will not extend horizontally to the area directly above the hook groove and the hook hole, so that the entire structure of the lock hook member "with two opposite ends (the first end portion and the second end portion) movably disposed in the hook groove and the hook hole respectively" will not contact the two fastening protrusions at all, so there will be no structural interference between any fastening protrusion and the lock hook member.

[0015] In one feasible embodiment, the two inner surfaces of at least two fastening protrusions can be arranged in a manner of facing each other, and the vertical projection of the inner surface of each fastening protrusion on the inner surface of the cap body will not fall on the lock hook member. Therefore, there is no structural interference problem between any fastening protrusion and the lock hook member.

[0016] In one feasible embodiment, in the steps of inserting the first processing tool of the first mold and the second processing tool of the second mold into the two opposite long sides of the initial cap body, the first carrier of the first mold and the second carrier of the second mold will not contact the two opposite long sides of the initial cap body (that is, the two opposite long sides of the cap body), thereby avoiding deformation of the initial cap body due to the impact of the first carrier of the first mold and the second carrier of the second mold, thereby improving the integrity of the outer structure of the cap body after production (that is, it can reduce unnecessary deformation of the cap body in appearance after production).

The following embodiments will further explain the relevant technical contents of the present invention in detail, but the disclosed contents are not intended to limit the scope of protection of the present invention.

[0031] It should be understood that although the terms first, second, third, etc. may be used herein to describe various elements or signals, these elements or signals should not be limited by these terms. These terms are mainly used to distinguish one element from another element or one signal from another signal. In addition, the term "or" used herein should include any one or more combinations of the associated listed items depending on the actual situation.

[0032] [First embodiment]

[0033] See also Figures 1 to 7 As shown, the first embodiment of the present invention provides a zipper head assembly structure Z, including: a sliding body 1 (or a slider), a pulling piece 2 (or a pull tab), a locking hook 3 (or a horse hook), a cap body 4 (or a cap) and a spring 5 (or a leaf spring), and the cap body 4 and the spring 5 can be combined into a cap structure S with multiple hole features.

[0034] First, cooperate Figures 1 to 4 As shown, the sliding body 1 has a first fixing seat 11 and a second fixing seat 12. The first fixing seat 11 has a hook groove 110 formed in the shape of a blind hole, and the second fixing seat 12 has a hook hole 120 formed in the shape of a through hole. An end portion 20 of the pulling piece 2 is arranged in an accommodating space 13 formed between the first fixing seat 11 and the second fixing seat 12. The lock hook member 3 is arranged on the sliding body 1, and the two opposite ends of the lock hook member 3 respectively have a first end portion 31 arranged in the hook groove 110 and a second end portion 32 passing through the hook hole 120 to form a stopper. The two opposite end portions 41 and 42 of the cap body 4 are respectively arranged on the first fixing seat 11 and the second fixing seat 12. The elastic sheet 5 is arranged between the inner surface 400 of the cap body 4 and the lock hook member 3 and presses against the lock hook member 3, and the lock hook member 3 and the elastic sheet 5 are both covered between the sliding body 1 and the cap body 4 (matching Figure 2 and Figure 3 shown).

[0035] Furthermore, cooperation Figures 5 to 7As shown, the cap body 4 has at least two inner grooves 40A corresponding to each other, at least two fixing protrusions 41A corresponding to each other and extending from the two inner grooves 40A respectively, and at least two through openings 42A corresponding to each other and adjacent to the at least two fixing protrusions 41A respectively, and the two fixing protrusions 41A can contact or abut the spring sheet 5, so that the spring sheet 5 is fixed by the two fixing protrusions 41A. In addition, the cap body 4 has an inner surface 400, an outer surface 401, and a lower surface 402 connected between the inner surface 400 and the outer surface 401. Among them, the two inner grooves 40A are concavely arranged on the inner surface 400 of the cap body 4, and the two through openings 42A penetrate the cap body 4 to form two hole features between the inner surface 400 and the outer surface 401 of the cap body 4 (i.e., the hole features formed by dotting from the outer surface 401 of the cap body 4 inward). Thus, since the two inner grooves 40A can be pre-formed on the inner surface 400 of the cap body 4, the thickness of the cap body 4 between the inner surface 400 and the outer surface 401 can be effectively reduced (i.e., the material is thinned to reduce the thickness), so that the present invention can easily form the through opening 42A and the fixing protrusion 41A at the same time by mechanical dotting.

[0036] It is worth noting that with Figure 2 and Figure 4 As shown, a vertical projection of one of the fastening protrusions 41A projected onto the first fixing seat 11 will not be projected onto the hook groove 100, and a vertical projection of the other fastening protrusion 41A projected onto the second fixing seat 12 will not be projected onto the hook hole 120. In other words, the two fastening protrusions 41A will not horizontally extend to the area directly above the hook groove 100 and the hook hole 120, thereby making it possible for the entire structure of the lock hook member 3 "with two opposite ends (the first end portion 31 and the second end portion 32) movably disposed in the hook groove 110 and the hook hole 120 respectively" to not contact the two fastening protrusions 41A at all, so there will be no structural interference between any fastening protrusion 41A and the lock hook member 3.

[0037] Furthermore, if Figure 6As shown, two inner grooves 40A may be diagonally disposed on the inner surface 400 of the cap body 4, and the two inner grooves 40A are respectively adjacent to the two opposite ends 4011, 4012 of the cap body 4. Two fixing protrusions 41A may be diagonally disposed in the two inner grooves 40A, and the two fixing protrusions 41A are respectively adjacent to the two opposite ends 4011, 4012 of the cap body 4. Two through openings 42A may be diagonally disposed on the outer surface 401 of the cap body 4, and the two through openings 42A are respectively adjacent to the two opposite ends 4011, 4012 of the cap body 4. In other words, since the two inner grooves 40A and the two fixing protrusions 41A are on the side of the inner surface 400 of the cap body 4, and the two through openings 42A are on the side of the outer surface 401 of the cap body 4, the positions of the two inner grooves 40A, the two fixing protrusions 41A or the two through openings 42A are roughly 90 degrees rotated relative to the two opposite ends 4011 and 4012 of the cap body 4.

[0038] For example, if Figure 5 As shown, each inner groove 40A has a first end 401A connected to the lower surface 402 of the cap body 4 and a second end 402A opposite to the first end 401A and away from the lower surface 402 of the cap body 4, and the width W of the inner groove 40A can be gradually narrowed from the first end 401A toward the second end 402A. Figure 6 and Figure 7 As shown, each of the securing protrusions 41A is adjacent to the second end 402A of the corresponding inner groove 40A, and each of the through openings 42A is adjacent to the second end 402A of the corresponding inner groove 40A.

[0039] It is worth noting that with Figures 5 to 7As shown, the inner surface 410A of each fixing protrusion 41A (that is, the fixing protrusion) extends laterally inward from the inner surface 400 of the cap body 4 (that is, it extends along the long axis direction of the cap body 4 rather than the short axis direction), and the inner surface 410A of each fixing protrusion 41A is inclined at an adjustable angle θ (that is, an adjustable angle) relative to the inner surface 400 of the cap body 4. In addition, each fixing protrusion 41A has an upper side end face 411A, a lower side end face 412A arranged opposite to the upper side end face 411A, and a front end face 413A connected between the upper side end face 411A and the lower side end face 412A. In addition, the spring piece 5 is supported by the two upper side end faces 411A of at least two fixing protrusions 41A to maintain on a predetermined plane P, and will not change due to the change of the adjustable angle θ. That is to say, no matter how the adjustable angle θ is adjusted or changed, the spring sheet 5 will be maintained on the predetermined plane P through the support of the two upper end surfaces 411A, and the spring sheet 5 will not be tilted due to the adjustment or change of the adjustable angle θ.

[0040] It is worth noting that Figure 8 As shown, according to different usage requirements, the cap structure S provided in the first embodiment of the present invention can be used in conjunction with another sliding body 1 and a locking hook member 3 that can cooperate with each other, so that the two inner surfaces 410A of at least two locking protrusions 41A are arranged in a face-to-face manner, and the inner surface 410A of each locking protrusion 41A is vertically projected (for example Figure 8 The vertical projection of the inner surface 400 of the cap body 4 (in the vertical projection direction shown by the imaginary line shown in the figure) will not fall on the lock hook 3. Therefore, there will be no mutual interference problem between any one of the fixing protrusions 41A and the lock hook 3 in structure.

[0041] [Second embodiment]

[0042] See also Figures 9 to 12 As shown, the second embodiment of the present invention provides a method for manufacturing a cap structure, which can be used to manufacture the cap structure S of the first embodiment. The method for manufacturing the cap structure comprises: first, Figure 8 and Fig. 9 As shown, a spring 5 is placed inside an initial cap body 4' (step S100); then, Fig. 9 , Fig.10 and Fig.11As shown, a first processing tool M11 of a first mold M1 and a second processing tool M21 of a second mold M2 are respectively inserted into two opposite long sides of the initial cap body 4' (that is, the cap body before processing, which can be made by die casting, injection molding or other forming methods), so that the present invention can form a cap body 4 with two fixing protrusions 41A by stamping (step S102); then, Fig. 9 , Fig.11 and Fig.12 As shown, the first mold M1 and the second mold M2 are removed (step S104 ).

[0043] Furthermore, if Fig.10 As shown, the cap body 4 has at least two inner grooves 40A corresponding to each other, at least two fixing protrusions 41A corresponding to each other and extending from the two inner grooves 40A respectively, and at least two through openings 42A corresponding to each other and adjacent to the at least two fixing protrusions 41A respectively, and the two fixing protrusions 41A can contact or abut the spring sheet 5, so that the spring sheet 5 is fixed by the two fixing protrusions 41A. In addition, the cap body 4 has an inner surface 400, an outer surface 401, and a lower surface 402 connected between the inner surface 400 and the outer surface 401. Among them, the two inner grooves 40A are concavely arranged on the inner surface 400 of the cap body 4, and the two through openings 42A penetrate the cap body 4 to form two hole features between the inner surface 400 and the outer surface 401 of the cap body 4 (i.e., the hole features formed by dotting from the outer surface 401 of the cap body 4 inward).

[0044] Furthermore, the first mold M1 has a first carrier M10 for carrying the first processing tool M11, and the second mold M2 has a second carrier M20 for carrying the second processing tool M21. In step S102, in which the first processing tool M11 of the first mold M1 and the second processing tool M21 of the second mold M2 are respectively inserted into the two opposite long sides of the initial cap body 4', the first carrier M10 of the first mold M1 and the second carrier M20 of the second mold M2 will not contact the two opposite long sides of the initial cap body 4' (that is, the two opposite long sides of the cap body 4), thereby avoiding the initial cap body 4' from being deformed due to the impact of the first carrier M10 of the first mold M1 and the second carrier M20 of the second mold M2, thereby improving the integrity of the appearance structure of the cap body 4 after the production is completed (that is, it can reduce the unnecessary deformation of the cap body 4 in appearance after the production is completed).

[0045] [Beneficial Effects of Embodiments]

[0046] One of the beneficial effects of the present invention is that the zipper head assembly structure Z, the cap structure S and the method for manufacturing the cap structure provided by the present invention can enable the spring piece 5 to be maintained on a predetermined plane without changing due to changes in the adjustable angle θ through the technical solutions of "the inner surface of each fixing protrusion 41A is inclined at an adjustable angle θ relative to the inner surface 400 of the cap body 4" and "the spring piece 5 is supported by each fixing protrusion 41A to be maintained on a predetermined plane P".

[0047] Furthermore, in one of the feasible embodiments, a vertical projection of one of the fastening protrusions 41A projected onto the first fixing seat 11 will not be projected onto the hook groove 100, and a vertical projection of the other fastening protrusion 41A projected onto the second fixing seat 12 will not be projected onto the hook hole 120. In other words, the two fastening protrusions 41A will not horizontally extend to the area directly above the hook groove 100 and the hook hole 120, thereby making it possible for the entire structure of the lock hook member 3, "the two opposite ends (the first end portion 31 and the second end portion 32) being movably disposed in the hook groove 110 and the hook hole 120 respectively", to not contact the two fastening protrusions 41A at all, so there will be no structural interference between any fastening protrusion 41A and the lock hook member 3.

[0048] Furthermore, in one of the feasible embodiments, the two inner surfaces 410A of at least two fastening protrusions 41A can be arranged in a manner of facing each other, and the vertical projection of the inner surface 410A of each fastening protrusion 41A on the inner surface 400 of the cap body 4 will not fall on the lock hook 3. Therefore, there is no structural interference problem between any fastening protrusion 41A and the lock hook 3.

[0049] Furthermore, in one feasible embodiment, in step S102 in which the first processing tool M11 of the first mold M1 and the second processing tool M21 of the second mold M2 are respectively inserted into the two opposite long sides of the initial cap body 4', the first carrier M10 of the first mold M1 and the second carrier M20 of the second mold M2 will not contact the two opposite long sides of the initial cap body 4' (that is, the two opposite long sides of the cap body 4), thereby avoiding deformation of the initial cap body 4' due to the impact of the first carrier M10 of the first mold M1 and the second carrier M20 of the second mold M2, thereby improving the integrity of the outer structure of the cap body 4 after production (that is, it can reduce unnecessary deformation of the cap body 4 in appearance after production).

[0050] Furthermore, the cap structure S provided in the embodiment of the present invention can form a structural design of "at least two inner grooves 40A corresponding to each other" by die-casting, and the cap structure S can form "at least two fixing protrusions 41A corresponding to each other and extending from the two inner grooves 40A respectively" and "at least two through openings 42A corresponding to each other and adjacent to the two fixing protrusions 41A" by mechanical dotting (for example, using a rivet knife to do the dotting). Therefore, when the spring sheet 5 is arranged on the inner surface 400 of the cap body 4, the two fixing protrusions 41A will contact the spring sheet 5, so that the spring sheet 5 is fixed by the two fixing protrusions 41A, so as to increase the processing efficiency and stability of the spring sheet 5 fixed in the cap body 4.

[0051] The contents disclosed above are only preferred feasible embodiments of the present invention, and therefore do not limit the protection scope of the claims of the present invention. Therefore, all equivalent technical changes made using the contents of the present invention description and drawings are included in the protection scope of the claims of the present invention.
