Description

Technical Field

[0001] This utility model relates to the field of zippers, and in particular to a quick-positioning split-end zipper pull. Background Technology

[0002] Split-end zippers replace the bottom stop at the zipper end with a dedicated pull tab. This allows the zipper to be pulled from both ends, keeping the top closed while simultaneously opening the bottom, increasing flexibility. When using split-end zippers, the top and bottom pull tabs are typically mounted opposite each other on the same side of the zipper belt. A pin from the other side is then passed through both tabs to connect them before the zipper can be pulled. However, in practice, users often only have one hand to hold both tabs while inserting the pin with the other. This inevitably leads to misalignment when the top and bottom pull tabs meet. This misalignment can cause the pin to be difficult to insert, or even jam, especially with plastic zipper teeth and pins, which can deform or be damaged in such situations. Utility Model Content

[0003] The main technical problem solved by this utility model is to provide a quick-positioning split zipper pull that can improve the accuracy and speed of alignment and prevent misalignment during alignment.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A quick-positioning split-end zipper pull head is provided. The split-end zipper pull head is installed on one side of the split-end zipper belt, opposite to the tail end of the split-end zipper pull head. The split-end zipper pull head includes: an upper wing plate, a lower wing plate, a connecting post, and a pull tab. The front ends of the upper and lower wing plates are connected by the connecting post to form a Y-shaped slide for the zipper belt to pass through. The upper wing plate is provided with a pull nose, and one end of the pull tab is inserted into the pull nose. An alignment guide mechanism is provided around the entrance of the Y-shaped slide formed by the tail ends of the upper and lower wing plates. The alignment guide mechanism consists of two upper alignment guide structures symmetrically arranged on both sides of the tail end of the upper wing plate and two lower alignment guide structures symmetrically arranged on both sides of the tail end of the lower wing plate. Each upper alignment guide structure includes an upper guide plate and an upper pressure plate. The upper guide plate extends rearward from the baffle on the corresponding side of the upper wing plate. The distance between the inner walls of the two upper guide plates is in lateral clearance fit with the tail end of the upper pull head. The upper pressure plate is higher than the upper surface of the upper wing plate, and the upper pressure plate is connected to the tail end of the upper wing plate through a guide ramp. Next, each lower alignment guide structure includes a lower guide plate and a lower support plate. The lower guide plate extends rearward from the baffle on the corresponding side of the lower wing plate. The distance between the inner walls of the two lower baffles is equal to the distance between the inner walls of the two upper guide plates. The lower support plate is located at the rear end of the lower wing plate. The height difference between the inner surface of the lower support plate and the inner surface of the lower wing plate is equal to the thickness of the lower wing plate of the upper pull head. The distance between the inner surface of the lower support plate and the lowest point of the guide slope is longitudinally interference-fitted with the tail end of the upper pull head.

[0005] In a preferred embodiment of this utility model, the upper guide plate and the upper pressure plate are connected together, and the lower guide plate and the lower support plate are connected together. The rear end faces of the upper guide plate, the lower guide plate, the upper pressure plate, and the lower support plate are flush. The rear end faces of the upper guide plate, the lower guide plate, the upper pressure plate, and the lower support plate are arc-shaped surfaces.

[0006] In a preferred embodiment of the present invention, the angle between the guide ramp and the upper surface of the upper wing plate is 30° to 45°.

[0007] In a preferred embodiment of this utility model, the width of the upper pressure plate is 1.5 to 3 mm, and the upper pressure plate is 1 to 1.5 mm higher than the upper wing plate.

[0008] In a preferred embodiment of this utility model, the pull tab is installed on the pull nose, and anti-slip ridges are provided around the two sides of the pull tab. The top of the pull tab is provided with a finger hole, and a stop block is provided at the intersection of the center line of the finger hole and the anti-slip ridge. When the pull tab is pulled down, the anti-slip ridges on both sides of the pull tab can just rest on the upper pressure plates on both sides.

[0009] The beneficial effects of this utility model are as follows: This utility model optimizes the structure of the pull-down head of the existing split-end zipper. By setting an alignment guide mechanism at the end of the pull-down head, even with one-handed operation, the upper and lower pull-down heads can be quickly and accurately aligned when they come into contact, without misalignment. This facilitates the continuous connection of the upper and lower pull-down heads by the pin, preventing the zipper from failing to pull up due to misalignment, and avoiding deformation and damage to the pin and chain teeth due to jamming.

[0011] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0012] Please see Figures 1 to 5 The embodiments of this utility model include: A quick-positioning split-end zipper pull head 10 is mounted on one side of the split-end zipper belt 30, opposite to the tail end of the split-end zipper pull head 20. The split-end zipper pull head 10 includes an upper wing plate 103, a lower wing plate 104, a connecting post 105, and a pull tab 101. The front ends of the upper wing plate 103 and the lower wing plate 104 are connected by the connecting post 105 to form a Y-shaped slide for the belt 30 to pass through. The upper wing plate 103 is provided with a pull nose 102, and the pull tab 101... One end is inserted into the nose 102. Around the entrance of the Y-shaped slide formed by the tail ends of the upper wing plate 103 and the lower wing plate 104, an alignment guide mechanism is provided. This alignment guide mechanism consists of two upper alignment guide structures symmetrically arranged on both sides of the tail end of the upper wing plate 103 and two lower alignment guide structures symmetrically arranged on both sides of the tail end of the lower wing plate 104. Each upper alignment guide structure includes an upper guide plate 1032 and an upper pressure plate 1031. The upper guide plate 1032 extends from the upper wing plate 104... The baffles on the corresponding sides of the 03 extend rearward to form a structure. The distance between the inner walls of the two upper guide plates 1032 is in lateral clearance fit with the tail end of the upper pull head 20. The upper pressure plate 1031 is higher than the upper surface of the upper wing plate 103. The upper pressure plate 1031 and the tail end of the upper wing plate 103 are connected by a guide ramp 1033. Each lower alignment guide structure includes a lower guide plate 1042 and a lower support plate 1041. The lower guide plate 1042 extends rearward from the baffle on the corresponding side of the lower wing plate 104. The structure is such that the distance between the inner walls of the two lower side baffles 1042 is equal to the distance between the inner walls of the two upper side guide plates 1032. The lower support plate 1041 is located at the rear end of the lower wing plate 104. The height difference between the inner surface of the lower support plate 1041 and the inner surface of the lower wing plate 104 is equal to the thickness of the lower wing plate of the upper pull head 20. The distance between the inner surface of the lower support plate 1041 and the lowest point of the guide slope 1033 is longitudinally interference-fitted with the tail end of the upper pull head 20.

[0013] The upper guide plate 1032 and the upper pressure plate 1031 are connected together, and the lower guide plate 1042 and the lower support plate 1041 are connected together. The rear end faces of the upper guide plate 1032, the lower guide plate 1042, the upper pressure plate 1031, and the lower support plate 1041 are flush. The rear end faces of the upper guide plate 1032, the lower guide plate 1042, the upper pressure plate 1031, and the lower support plate 1041 are arc-shaped. This improves the overall structural strength and visual effect of the two upper alignment guide structures and the two lower alignment guide structures. Moreover, the arc-shaped rear end faces facilitate the insertion of the tail end of the upper pull head 20 between the upper and lower alignment guide structures during alignment without jamming.

[0014] The angle between the guide ramp 1033 and the upper surface of the upper wing plate 103 is 30° to 45°. If the angle is too large, the resistance during sliding will be large; if the angle is too small, the guide ramp 1033 will be too long. Therefore, the angle is between 30° and 45°, and the actual angle used is 41°.

[0015] The width of the upper pressure plate 1041 is 1 to 1.5 mm, and the upper pressure plate 1041 is 1 to 1.5 mm higher than the upper surface of the upper wing plate 104. The actual designed width of the upper pressure plate 1041 is 1.48 mm, and the height difference between the upper pressure plate 1041 and the upper surface of the upper wing plate 104 is 1.1 mm. The reason for using the above values ​​is that the pull-down head 10 itself is relatively small. If the upper pressure plate 1031 is too wide, the pull-down head 20 will be inserted too deeply, resulting in greater resistance when pulling it open. In addition, the height difference between the upper pressure plate 1031 and the upper wing plate 103 cannot be too large, otherwise it will easily affect the direction of force when the pull tab 101 is pulled down.

[0016] The pull tab 101 is mounted on the pull nose 102. Anti-slip raised lines 1011 are provided around the two sides of the pull tab 101. The top of the pull tab 101 is provided with a finger hole 1013. A stop block 1012 is provided at the intersection of the center line of the finger hole 1013 and the anti-slip raised line 1011. When the pull tab 101 is pulled down, the anti-slip raised lines 1011 on both sides of the pull tab 101 can just rest on the upper pressure plates 1031 on both sides. The structure of anti-slip raised lines 1011, finger holes 1013, and stop blocks 1012 on the pull tab 101 can effectively prevent slippage when pulling. Moreover, the two upper pressure plates 1031 can serve as the resting positions for the pull tab 101, making the pull tab 101 slightly tilted, preventing it from getting stuck between the fabric covering lines on both sides of the chain belt 30. This makes it easy for fingers to find and reduces the friction between the surface of the pull tab 101 and the upper wing plate 103, preventing the trademark pattern in the middle of the pull tab 101 from becoming smudged.

[0017] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
