DETAILED DESCRIPTION

[0034] In view of this, the core of the present invention is to provide a zipper head to increase the sales volume of waterproof zippers.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] like Figures 1 to 7 As shown, an embodiment of the present invention discloses a zipper head for a waterproof zipper, the waterproof zipper includes a cloth tape 500 and a chain tooth 600 connected to the cloth tape 500, a waterproof film 501 is adhered to one side of the cloth tape 500, and the zipper head includes a slider body 100, a horse hook 200, a pull tab 300 and an elastic element 400.

[0037] The slider body 100 includes a first wing plate 101, a second wing plate 102 and a connecting piece 103. The plane where the first wing plate 101 is located is parallel to the plane where the second wing plate 102 is located. The connecting piece 103 is used to connect the first wing plate 101 and the second wing plate 102. A gap capable of accommodating the cloth tape 500 is formed between the first wing plate 101 and the second wing plate 102. The first wing plate 101 is located on the side of the cloth tape 500 where the waterproof film 501 is adhered, and the second wing plate 102 is located away from the side where the waterproof film 501 is adhered to the cloth tape 500. In order to facilitate the arrangement of the cloth tape 500 and the chain teeth 600 of the waterproof zipper in the gap between the first wing plate 101 and the second wing plate 102, the slider body 100 can move along the length direction of the chain teeth 600 as the pull tab 300 is pulled, so that the chain teeth 600 are engaged together; the horse hook 200 is rotatably connected to the connecting member 103, and the hook needle 201 of the horse hook 200 is located on the side of the cloth tape 500 away from the waterproof membrane 501, so that when the slider body 100 moves, the hook needle 201 of the horse hook 200 will not scratch the waterproof membrane 501. The waterproof film 501 is scratched, the printing on the waterproof film 501 falls off, or pinhole marks are left on the waterproof film 501 due to the hook 200 staying on the waterproof film 501. The second wing plate 102 is provided with a slot for the hook 201 to pass through, so that the hook 201 can pass through the slot and be locked with the chain tooth 600 as the hook 200 rotates, so as to achieve self-locking; the pull tab 300 can pull the hook 200 to rotate, and the pull tab 300 can be detachably connected to one end of the connector 103 close to the first wing plate 101, so as to pass through the second wing plate 102. The pull tab 300 drives the horse hook 200 to rotate, and the rotation of the horse hook 200 realizes engagement and disengagement with the chain tooth 600, thereby realizing self-locking and unlocking; the elastic element 400 is arranged between the horse hook 200 and the slider body 100, so that after the pull tab 300 is loosened, the compression force of the elastic element 400 can push the horse hook 200 to rotate in the opposite direction. As the horse hook 200 rotates in the opposite direction, the hook needle 201 of the horse hook 200 passes through the slot and clamps the chain tooth 600, realizing the locking function, so that the zipper head cannot slide on the chain tooth 600.

[0038] When using the zipper head provided by the invention, the tape 500 of the waterproof zipper is placed between the first wing plate 101 and the second wing plate 102 of the slider body 100. Since the horse hook 200 is rotatably connected to the connecting member 103, the pull tab 300 can pull the horse hook 200 to rotate. The elastic element 400 is arranged between the horse hook 200 and the slider body 100. Therefore, pulling the pull tab 300 (i.e. rotating the pull tab 300) can make the horse hook 200 overcome the compression force of the elastic element 400 and rotate, so that the horse hook 200 The hook 201 gradually rotates in the direction of the slot away from the second wing plate 102, and finally disengages from the chain tooth 600 of the waterproof zipper, thereby unlocking the zipper head and allowing the zipper head to slide on the chain tooth 600; when the pull tab 300 is released, the horse hook 200 rotates in the opposite direction under the compression force of the elastic element 400. As the horse hook 200 rotates in the opposite direction, the hook 201 of the horse hook 200 passes through the slot and gets stuck on the chain tooth 600, thereby realizing the locking function and preventing the zipper head from sliding on the chain tooth 600. It can be seen that the hook 201 of the horse hook 200 of the zipper head provided by the present invention is located on the side of the cloth tape 500 away from the waterproof membrane 501, and the pull tab 300 is detachably connected to one end of the connector 103 close to the first wing plate 101, and the first wing plate 101 is located on the side of the cloth tape 500 on which the waterproof membrane 501 is adhered, that is, the pull tab 300 and the hook 201 of the horse hook 200 are respectively located on both sides of the cloth tape 500. When the pull tab 300 is pulled, the hook 201 of the horse hook 200 is always on the side away from the waterproof membrane 501. Therefore, the horse hook 200 will not scratch the waterproof membrane 501, thereby reducing the occurrence of scratches on the waterproof membrane 501, the falling off of the printing on the waterproof membrane 501, or the pinhole marks left by the horse hook 200 staying on the waterproof membrane 501, thereby improving the waterproof effect and appearance quality of the waterproof zipper, thereby increasing the sales of the waterproof zipper.

[0039] It should be noted that the above-mentioned connecting member 103 can be a structure with a connecting block, a U-shaped column or two oppositely arranged connecting plates. As long as the structure can meet the use requirements, it belongs to the protection scope of the present invention; preferably, the connecting member 103 provided in the embodiment of the present invention is two oppositely arranged connecting plates, namely a first connecting plate 1031 and a second connecting plate 1032, and a first rotating cavity that can accommodate the horse hook 200 is formed between the first connecting plate 1031 and the second connecting plate 1032, and the horse hook 200 can rotate in the first rotating cavity, so that when the pull tab 300 pulls the horse hook 200 to rotate, the horse hook 200 can rotate in the first rotating cavity, thereby realizing the engagement and disengagement of the hook hook 201 and the chain tooth 600, and realizing self-locking and unlocking.

[0040] Furthermore, the connection method between the connector 103 and the pull tab 300 can be a pin connection, a threaded connection or a barbed connection, and any method that can achieve a detachable connection between the pull tab 300 and the connector 103 falls within the protection scope of the present invention; preferably, the present invention provides two specific connection methods.

[0041] Specifically, Figure 1 , Figures 3 to 6 The figure shows a first connection method between the connecting member 103 and the pull tab 300 provided in an embodiment of the present invention. A rotating clamping groove 1033 for clamping the pull tab 300 is provided on the connecting member 103. An end of the pull tab 300 close to the rotating clamping groove 1033 is provided with a pushing structure 301 that can cooperate with the rotating clamping groove 1033, and the rotating clamping groove 1033 is provided with a second rotating cavity that can rotate the pushing structure 301, so that the pull tab 300 can be clamped to the rotating clamping groove 1033 through the pushing structure 301. When the pull tab 300 is pulled, the pushing structure 301 can be driven to rotate in the second rotating cavity, so that the pushing structure 301 pushes the horse hook 200 to rotate.

[0042] It should be noted that the rotating snap-fitting slot 1033 may be circular, square or polygonal in shape, and any shape that can meet the use requirements belongs to the protection scope of the present invention; preferably, the embodiment of the present invention adopts a circular rotating snap-fitting slot 1033.

[0043] Furthermore, the opening of the rotating clamping slot 1033 should not be too large to prevent the pushing structure 301 from escaping from the opening of the rotating clamping slot 1033 and failing to push the horse hook 200 to rotate, thereby rendering the zipper head unusable.

[0044] In addition, the pushing structure 301 can be a spherical, arc-shaped or rectangular structure. As long as the pushing structure 301 can push the horse hook 200 to rotate, it belongs to the protection scope of the present invention; preferably, the pushing structure 301 provided in the embodiment of the present invention adopts an L-shaped block structure to facilitate a larger contact area with the horse hook 200, so that when the pull tab 300 is pulled, the movement of the slider body 100 is smoother.

[0045] Furthermore, the pull tab 300 is provided with an avoidance hole 302 capable of accommodating the side wall of the rotating engaging groove 1033, so as to prevent the pull tab 300 from interfering with the connecting member 103 during rotation, resulting in the pull tab 300 being unable to be pulled and the slider body 100 being stuck when moving on the chain tooth 600.

[0046] It should be noted that the avoidance hole 302 may be rectangular, elliptical or irregular in shape, and any shape that can avoid interference between the pull tab 300 and the connector 103 falls within the protection scope of the present invention. Preferably, the embodiment of the present invention adopts a rectangular avoidance hole 302, which has a simple structure and is easy to process and manufacture.

[0047] like Figure 7 The figure shows a second connection method between the connecting member 103 and the pull tab 300 provided in an embodiment of the present invention. The pull tab 300 is provided with a first rotating connection hole 303, and the horse hook 200 is provided with a second rotating connection hole 2021. The first rotating connection hole 303 and the second rotating connection hole 2021 are connected by a pin shaft, that is, the pull tab 300 and the horse hook 200 are directly connected, and the horse hook 200 is rotationally connected to the connecting member 103, thereby indirectly realizing a detachable connection between the pull tab 300 and the connecting member 103. When the pull tab 300 is pulled, the pull tab 300 drives the horse hook 200 to rotate, so that the hook needle 201 of the horse hook 200 is engaged and disengaged with the chain tooth 600, thereby realizing self-locking and unlocking.

[0048] like Figure 2 As shown, the horse hook 200 includes a first connecting rod 202, a second connecting rod 203 connected to the first connecting rod 202, and a hook needle 201 arranged at an end of the second connecting rod 203 away from the first connecting rod 202. A central axis hole 2022 is provided at the connection between the first connecting rod 202 and the second connecting rod 203, and a matching axis hole 1034 is provided on the connecting piece 103. The central axis hole 2022 and the matching axis hole 1034 are connected by a pin shaft to facilitate the rotational connection between the horse hook 200 and the connecting piece 103.

[0049] It should be noted that the elastic element 400 can be a spring, rubber or foam type, as long as it has a compressive force after being compressed and can push the horse hook 200 to rotate. Preferably, the embodiment of the present invention uses a spring, which has a simple structure and is easy to process and manufacture.

[0050] Furthermore, a raised structure 1021 for thickening the second wing plate 102 is provided on the side of the second wing plate 102 away from the first wing plate 101, so as to improve the strength of the slider body 100 and extend the service life of the zipper head; and, the raised structure 1021 is provided with a groove capable of accommodating the horse hook 200, so as to prevent interference between the horse hook 200 and the raised structure 1021, resulting in the horse hook 200 being unable to rotate to engage with the chain tooth 600, that is, unable to achieve self-locking, affecting the normal use of the zipper head.

[0051] like Figure 8 and Fig. 9The present invention further discloses a zipper, comprising a zipper head as described in any one of the above, and thus has all the technical effects of the above zipper heads, which will not be described in detail herein.
