Description

TECHNICAL FIELD

[0001] The utility model relates to a double -sided self -locking zipper head. BACKGROUND

[0002] The zipper head is an important component in the zipper system, which is used to open and close the zipper. The zipper head is usually made of metal (such as zinc alloy, stainless steel) or plastic, which contains a handle that can be gripped and an internal mechanical device that can make the two rows of teeth interlock or separate. When pulling the zipper head, its internal mechanism will push the two rows of teeth together and make them interlock, thereby closing the zipper. Conversely, pulling the zipper head in the opposite direction will separate the teeth and thus open the zipper.

[0003] In some cases, such as sports clothes or outdoor equipment, a stronger grip may be required. In other cases, such as high-end clothing, a smaller and more delicate puller design may be preferred to allow the same zipper to adapt to a variety of different application requirements, or when a damaged puller needs to be replaced. Chinese patent application No. CN202223441430.6 discloses a double-sided self-locking zipper head. A connecting mechanism is provided between the zipper body and the plastic pull rod. After the plastic pull rod drives the rod to insert into the through slot, the rod can be extruded to insert into the groove under the action of the spring to position the rod, and the plastic pull rod can be installed on the zipper head body through the double-sided self-locking mode and is also convenient to disassemble and replace. However, due to the elasticity of the spring itself, the spring may fail during continuous compression and resetting, which may cause inconvenience in disassembling and assembling the puller.

[0004] Therefore, how to realize the disassembly of the puller while avoiding spring failure and preventing the damage of parts during repeated disassembly of the puller has become a problem that needs to be solved by those skilled in the art. SUMMARY

[0005] In view of the deficiencies of the prior art, the utility model aims to provide a double-sided self-locking zipper head that can disassemble the pull rod from the body and replace it with a new one after separating the connecting mechanism from the body.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a body, a pull rod, and a connecting mechanism. The pull rod is located below the body and is rotatably installed on the body through the connecting mechanism. The connecting mechanism includes a rotating part and a connecting part. The rotating part is rotatably installed on the body. The connecting part is two pieces and is fixedly installed on the left and right sides of the pull rod, respectively. Each connecting part is located on the left and right sides of the rotating part and is detachably connected with the rotating part.

[0007] The utility model further sets up: each connecting portion all includes connecting plug -in block and fixed plate of rotation installation on connecting plug -in block, each connecting plug -in block all is made of easy material quality of deformation, the rotating portion includes pivot and rotating block at the left and right sides of pivot, each rotating block all is provided with the connecting insertion slot of connecting plug -in block insertion, each fixed plate is detachable with corresponding rotating block respectively.

[0008] The utility model further sets up: each connecting plug -in block all is set up in the ladder type of upper narrow lower wide, each connecting plug -in block all includes alignment surface, each alignment surface all is from below to above and is set up from inside to outside.

[0009] The utility model further sets up: each rotating block all is located in the limit stop plug -in block of corresponding connecting insertion slot protruding setting, each connecting plug -in block all is provided with the limit stop slot of limit stop plug -in block insertion.

[0010] The utility model further sets up: each limit stop plug -in block all is set up in the three prism of upper narrow lower wide.

[0011] The utility model further sets up: the pull rod includes upper connecting section and lower connecting section, and each connecting plug -in block and fixed plate are located on the upper connecting section, and a plurality of contact grooves are formed on the upper connecting section.

[0012] The utility model further sets up: the left and right sides of lower connecting section are respectively recessed and are provided with cooperation groove.

[0013] The utility model further sets up: the lower connecting section is provided with a plurality of contact convex strips with length extending along front and back between cooperation groove.

[0014] By adopting the above technical scheme, since each connecting portion is detachably connected with the rotating portion, when the pull rod is damaged and needs to be replaced, the connecting portion and the rotating portion are separated, so that the connecting portion and the pull rod fixed with the connecting portion are taken off from the main body, which brings convenience for disassembling the pull rod, and in the production process of the zipper head, different design styles of pull rods can be manufactured, so that when the same zipper needs to adapt to multiple different application requirements, the appropriate style of pull rod can be more efficiently selected to meet more requirements.

[0025] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0026] As Figures 1-6The utility model discloses a double -sided self -locking zipper head, including installing on the zipper and realizing the body 1 (the cooperation mode of body 1 and zipper is prior art, here does not make specific elaboration) of zipper opening and closing, the pull rod 2 of the material quality of easy deformation is made and connecting mechanism 3, the pull rod 2 is located below body 1 and is rotatably installed on body 1 through connecting mechanism 3, connecting mechanism 3 includes rotating part 31 and connecting part 32, rotating part 31 is rotatably installed on body 1, the quantity of connecting part 32 is two and is respectively fixedly installed on the left and right sides of pull rod 2 through buckle, integral molding etc.

[0027] Among them, each connecting part 32 includes connecting plug block 321 and fixed plate 322 rotatably installed on connecting plug block 321, each connecting plug block 321 is made of rubber and other material quality of easy deformation, rotating part 31 includes rotating shaft 311 in body 1 and rotating block 312 on the left and right sides of rotating shaft 311, each rotating block 312 is provided with connecting insertion groove 3121 for the insertion of connecting plug block 321, each fixed plate 322 is detachably connected with the corresponding rotating block 312, since each connecting plug block 321 is made of material quality of easy deformation, after inserting the connecting plug block 321 on the left and right sides of pull rod 2 into the connecting insertion groove 3121 of the corresponding rotating block 312, the fixed plate 322 on each connecting plug block 321 can be moved downwards to complete the detachable connection (such as bolt, magnetic attraction etc.) of fixed plate 322 and the corresponding rotating block 312, and when the pull rod 2 needs to be detached from body 1, the fixed plate 322 is first separated from the corresponding rotating block 312, and then the connecting plug block 321 is moved outward to separate it from the corresponding connecting insertion groove 3121, so that the pull rod 2 can be removed from body 1.

[0028] Preferably, each of the connecting plugs 321 is arranged in a stepped shape with a narrow upper part and a wide lower part, and each of the connecting plugs 321 comprises an alignment surface 3211 arranged from inside to outside from bottom to top. Since each of the connecting plugs 321 is narrow at the top and wide at the bottom, and each of the alignment surfaces 3211 is located at the inner side of the corresponding connecting plug 321, when each of the connecting plugs 321 is inserted into the connecting slot 3121 of the corresponding rotating block 312, the innermost side of each of the connecting plugs 321 needs to be aligned with the corresponding connecting slot 3121. Compared with the length direction along the upper and lower extending plane, each of the connecting plugs 321 can more smoothly enter the corresponding connecting slot 3121 to realize the cooperation between the connecting plug 321 and the connecting slot 3121.

[0029] Each of the rotating blocks 312 is arranged to protrude a limiting plug 3122 in the corresponding connecting slot 3121. Each of the connecting plugs 321 is arranged with a limiting slot 3212 for the limiting plug 3122. After each of the connecting plugs 321 is inserted into the corresponding connecting slot 3121, since each of the limiting plugs 3122 exists, when each of the connecting plugs 321 is inserted into the corresponding connecting slot 3121, the inner side of each of the connecting plugs 321 needs to forcibly pass the outer side of each of the limiting plugs 3122 to realize the limiting plug 3122 entering the limiting slot 3212, thereby completing the relative position determination between each of the connecting plugs 321 and the corresponding rotating block 312, and making each of the connecting plugs 321 stably located in the corresponding connecting slot 3121 without moving in and out, thereby facilitating the fixed connection between the fixed plate 322 and the corresponding rotating block 312.

[0030] Preferably, each of the limiting plugs 3122 is arranged in a triangular prism shape with a narrow upper part and a wide lower part. Since each of the limiting plugs 3122 is narrow at the top and wide at the bottom, when each of the connecting plugs 321 is inserted into the corresponding connecting slot 3121, each of the limiting plugs 3122 can more efficiently and smoothly align with the corresponding limiting slot 3212 to complete the insertion into the corresponding limiting slot 3212, thereby realizing the relative position determination between each of the connecting plugs 321 and the corresponding rotating block 312.

Since the upper connecting section 21 is arranged with a plurality of contact grooves 211, the roughness of the surface of the upper connecting section 21 can be increased, the friction of the upper connecting section 21 can be improved, and the situation of hand slipping when holding the upper connecting section 21 can be reduced.

[0032] The left and right sides of the lower connecting section 22 are respectively provided with matching grooves 221 which are concave inwardly, and the presence of each matching groove 221 enables the user to hold the matching grooves 221 on both sides during the process of applying force to the pull rod 2 to drive the slider body 1 to move up and down, thereby applying force to the lower connecting section 22.

[0033] The lower connecting section 22 is provided with a plurality of contact protrusions 222 which extend along the front and back between the matching grooves 221, and when the user directly contacts the part of the lower connecting section 22 between the matching grooves 221, the contact protrusions 222 can reduce the occurrence of slipping between the hand and the lower connecting section 22 when holding the lower connecting section 22.

[0034] The above description of disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application.
