Description

Technical Field

[0001] This utility model relates to zipper heads, and more particularly to a spliced ​​zipper head. Background Technology

[0002] Zippers, as a common connector, are widely used in clothing, bags, tents, medical equipment and other fields. Their main function is to open and close by interlocking two adjacent teeth. The zipper head, as one of the core components of the zipper, is responsible for guiding the teeth to engage or disengage. Its structural design directly affects the zipper's performance, durability and manufacturing cost.

[0003] Traditional zipper pulls are usually made using one-piece casting or stamping processes. While these processes meet basic usage requirements to some extent, they also have some obvious limitations. For example, if the zipper pull is damaged, the entire zipper often needs to be replaced, resulting in resource waste and inconvenience.

[0004] Therefore, how to achieve the separate splicing of zipper heads to reduce the replacement cost of zipper heads has become an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a spliced ​​zipper head that can be separated into upper and lower mounting parts to replace the worn parts and thus extend the service life of the unworn parts.

[0006] To achieve the above objectives, the present invention provides the following technical solution: including a pull tab and a housing, the pull tab being located on the front side of the housing, the housing including an upper mounting part and a lower mounting part, the upper mounting part and the lower mounting part being detachably connected, a connecting plug being detachably mounted on the upper mounting part, and the pull tab being located on the connecting plug.

[0007] The present invention is further configured such that: the upper mounting part protrudes downward with an upper positioning block, the lower mounting part protrudes upward with a lower positioning block, the lower positioning block is provided with a positioning groove for the upper positioning block to be inserted, and the left and right sides of the upper mounting block are in contact with the inner wall of the lower positioning block.

[0008] The present invention is further configured such that: the upper positioning block is made of a material that is prone to deformation; the interior of the upper positioning block is hollow and includes a first connecting segment, a second connecting segment and a third connecting segment from top to bottom; the width of the second connecting segment is adapted to the width of the positioning groove; the lower positioning block is located above the second connecting segment and has limit blocks on both the left and right sides, and the inner side of each limit block abuts against the first connecting segment.

[0009] The present invention is further configured such that: the third connecting section is located in the positioning groove and includes a left loading part and a right loading part, the left loading part and the right loading part are symmetrically arranged, the left loading part includes a guide surface on the left side, and the guide surface is inclined from top to bottom and from left to right.

[0010] The present invention is further configured such that: both the left and right sides of the connecting plug are open and the front side is rotatably mounted on the upper mounting part, and the rear side is detachably connected to the upper mounting part.

[0011] The present invention is further configured such that: a connecting plate is detachably installed on the rear side of the connecting plug, the upper mounting part is provided with a connecting groove corresponding to the connecting plate, and plug holes are provided through the left and right sides of the connecting plate, while screw holes are provided on the upper mounting part corresponding to each plug hole.

[0012] The present invention is further configured such that the pull tab is provided with a circular hole.

[0013] By adopting the above technical solution, since the upper mounting part equipped with the pull tab can be detachably connected to the lower mounting part, if one of the upper mounting part and the lower mounting part is worn during the use of the zipper head, the two can be separated and the unworn part can be retained. After replacing the worn part and completing the assembly, the unworn part can continue to be used, thereby extending the service life of the entire zipper head. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-5 As shown, this utility model discloses a spliced ​​zipper head, including a pull tab 1 and a housing 2 (chain teeth and other structures are not shown). The pull tab 1 is located on the front side of the housing 2. The housing 2 includes an upper mounting part 21 and a lower mounting part 22, which are detachably connected. A connecting plug 211 is detachably mounted on the upper mounting part 21, and the pull tab 1 is located on the connecting plug 211. Since the upper mounting part 21 with the pull tab 1 can be detachably connected to the lower mounting part 22, if one of the upper mounting part 21 and the lower mounting part 22 is worn during the use of the zipper head, the two can be separated and the unworn part can be retained. After replacing the worn part and completing the assembly, the unworn part can continue to be used, thereby extending the service life of the entire zipper head.

[0026] In addition, the upper mounting part 21 and the lower mounting part 22 can be fixed together by magnetic attraction, snap fasteners or other means. In this embodiment, snap fastener connection is used, which will not be described in detail here.

[0027] The upper mounting part 21 has an upper positioning block 212 protruding downwards, and the lower mounting part 22 has a lower positioning block 221 protruding upwards. The lower positioning block 221 has a positioning groove 222 for the upper positioning block 212 to be inserted into. The left and right sides of the upper mounting block are in contact with the inner wall of the lower positioning block 221. When the upper mounting part 21 and the lower mounting part 22 are installed together, the upper positioning block 212 of the upper mounting part 21 will fall into the positioning groove 222 of the lower positioning block 221. At this time, the circumference of the upper positioning block 212 will be in contact with the inner wall of the positioning groove 222, so that the upper positioning block 212 cannot move relative to the lower mounting part 22. This determines the relative position of the upper mounting part 21 and the lower mounting part 22, thus facilitating the fixing of the two.

[0028] The upper positioning block 212 is made of a material that is easily deformable, such as rubber. The interior of the upper positioning block 212 is hollow and includes, from top to bottom, a first connecting segment 2121, a second connecting segment 2122, and a third connecting segment 3. The width of the second connecting segment 2122 is adapted to the width of the positioning groove 222. The lower positioning block 221 is located above the second connecting segment 2122, with limit blocks 2211 on both its left and right sides. The inner side of each limit block 2211 abuts against the first connecting segment 2121. Because the upper positioning block 212 is made of a material that is easily deformable, when the relative positions of the upper mounting part 21 and the lower mounting part 22 are determined, the third connecting segment 3, the second connecting segment 2122, and the first connecting segment 2121 of the upper positioning block 212, which are moving downwards into the positioning groove 222, will sequentially move downwards towards the positioning groove 222. The lower positioning block 221 is positioned in the positioning groove 222. Since the lower positioning block 221 is located on the left and right sides above the second connecting section 2122, the second connecting section 2122 needs to be squeezed and deformed to reach the positioning groove 222. This allows the limiting block 2211 to be positioned above the second connecting section 2122 for pressing. At this time, without the action of external force, the second connecting section 2122 cannot move upward past the limiting block 2211, thus allowing the upper positioning block 212 to be stably positioned in the positioning groove 222. This determines the relative position of the upper mounting part 21 and the lower mounting part 22, providing convenience for fixing the two. At the same time, since the interior of the upper positioning block 212 is hollow, it can smoothly deform during the process of moving downward into the positioning groove 222.

[0029] Preferably, the third connecting segment 3 is located within the positioning groove 222 and includes a left loading portion 31 and a right loading portion 32, which are symmetrically arranged. The left loading portion 31 includes a guide surface 311 on the left side, which is inclined from top to bottom and from left to right. Because the guide surface 311 is inclined and the left loading portion 31 and right loading portion 32 are symmetrical, during the alignment process of the upper positioning block 212 downwards with the positioning groove 222... First, the third connecting segment 3 at the bottom of the upper positioning block 212 is aligned with the positioning groove 222. Due to the setting of its guide surface 311, the third connecting segment 3 can be aligned with the positioning groove 222 more smoothly and deform inward, so that the second connecting segment 2122 forcibly passes through each limiting block 2211, thereby realizing that the second connecting segment 2122 is located in the positioning groove 222 and fits against the inner wall of the lower positioning block 221, thus realizing the cooperation between the upper positioning block 212 and the lower positioning block 221.

[0030] Furthermore, the connecting plug 211 has openings on both the left and right sides, with the front side rotatably mounted on the upper mounting part 21 and the rear side detachably connected to the upper mounting part 21 by bolts or other means. Since the front side of the connecting plug 211 is rotatably mounted on the upper mounting part 21 and the rear side is detachable from the upper mounting part 21, after separating the rear side of the connecting plug 211 from the upper mounting part 21 and flipping the connecting plug 211 upwards, the pull tab 1 can be inserted into the connecting plug 211. Then, by rotating the connecting plug 211 downwards to achieve its cooperation with the upper mounting part 21, the pull tab 1 can be stably positioned on the connecting plug 211 of the upper mounting part 21. When the pull tab 1 wears out during use, it can be removed and replaced by separating the rear side of the connecting plug 211 from the upper mounting part 21.

[0031] The connecting block 211 has a detachable connecting plate 4 mounted on its rear side facing downwards. The upper mounting part 21 has a connecting groove 213 corresponding to the connecting plate 4. The connecting plate 4 has through holes 41 on both its left and right sides. The upper mounting part 21 has screw holes 214 corresponding to each hole 41. Therefore, after the pull tab 1 is inserted into the connecting block 211, it can be flipped downwards to allow the connecting plate 4 on the connecting block 211 to enter the connecting groove 213 of the upper mounting part 21. Then, the bolts that are compatible with the screw holes 214 are inserted into each hole 41 to complete the threaded engagement with the corresponding screw holes 214. This makes the connecting plate 4 of the connecting block 211 stably connected to the upper mounting part 21, so that the pull tab 1 will not separate from the upper mounting part 21. When it is necessary to remove the pull tab 1, the bolts are rotated to remove it from the corresponding screw holes 214, and the connecting block 211 can be rotated downwards to remove the pull tab 1 located on the connecting block 211.

[0032] Additionally, it is worth noting that in this embodiment, the connecting plate 4 is made of a material that is easily deformable, such as rubber. Therefore, after deforming the connecting plate 4 by bringing the hole on the pull tab 1 for the connecting plate 4 and the connecting plug 211 into close to the connecting plate 4, the connection between the pull tab 1 and the connecting plug 211 can be achieved. Alternatively, the connecting plate 4 can be removed directly so that the pull tab 1 can be inserted into the connecting plug 211, and then the connecting plate 4 can be fitted with the connecting plug 211 by means of buckles, bolts, etc. At this time, the connecting plug 211 can be rotated downward so that the connecting plate 4 will fall into the connecting groove 213.

[0033] The pull tab 1 is provided with a round hole 11, which can be used to pull the pull tab 1 conveniently, especially when wearing gloves or when finger dexterity is limited; in addition, it can also be used to hang some small ornaments or key rings, etc., increasing the possibility of personalized decoration.
