Technical Field

[0001] The utility model relates to the technical field of zippers, in particular to a chimeric zipper. Background Art

[0002] A zipper consists of chain teeth, a slider, upper and lower stops or locking parts. The zipper relies on continuously arranged chain teeth to combine or separate objects.

[0003] The two rows of chain teeth of the zipper are interlocked to close the items. When the slider is pulled, the pull tab is in an unfixed state and there is a possibility that the pull tab may flip and get stuck, which requires adjustment of the pull tab when pulling the slider, causing trouble in operation.

[0004] In view of this, we propose a chimeric zipper. Utility Model Content

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art, meet practical needs, and provide a chimeric zipper to solve the current technical problem that the pull tab is in an unfixed state and may be flipped and stuck, resulting in the need to adjust the pull tab when pulling the slider.

[0007] Chain tooth bar;

[0008] Two cloth strips are respectively fixed on the outer ends of two rows of chain teeth of the chain tooth strip;

[0009] The chain head is movably arranged on the chain tooth bar;

[0010] One end of the pull tab is rotatably connected to the chain head through a U-shaped frame;

[0011] Wherein, the two ends of the U-shaped frame are respectively positioned and matched with the chain head through positioning structures;

[0012] The positioning structure includes a fixing block, a connecting block A, an elastic sheet, a connecting block B and an arc-shaped clamping block;

[0013] The fixing block is fixedly arranged at the side end of the chain head;

[0017] Two arc-shaped clamping blocks are respectively fixed on the top ends of the two connecting blocks B;

[0018] Wherein, the two arc-shaped clamping blocks are clamped and matched with the ends of the U-shaped frame.

[0019] Preferably, the elastic sheet adopts a V-shaped structure design, and the two opening ends of the elastic sheet are opposite to each other.

[0020] Preferably, two elastic sheets are provided with vertical sections at opposite ends.

[0021] Preferably, a gap is left between opposite ends of the two elastic sheets.

[0022] Preferably, a clamping opening is formed between the tops of the two arc-shaped clamping blocks.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0032] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0033] Embodiment 1: A chimeric zipper, see Figures 1 to 4 , including a sprocket strip 1, a cloth strip 2, a chain head 3 and a pull tab 5;

[0034] Two cloth strips 2 are respectively fixed on the outer ends of two rows of chain teeth of the chain tooth bar 1; the chain head 3 is movably arranged on the chain tooth bar 1; one end of the pull tab 5 is rotatably connected to the chain head 3 through a U-shaped frame 4; wherein, the two ends of the U-shaped frame 4 are respectively positioned and matched with the chain head 3 through positioning structures 6;

[0035] The positioning structure 6 includes a fixing block 601, a connecting block A 602, an elastic sheet 603, a connecting block B 604 and an arc-shaped clamping block 605;

[0036] The fixed block 601 is fixed on the side end of the chain head 3; the two connecting blocks A602 are symmetrically fixed on the top side of the fixed block 601; one end of the two elastic sheets 603 is fixedly connected to the top of the two connecting blocks A602 respectively; the two connecting blocks B604 are fixed on the other ends of the two elastic sheets 603 respectively; the two arc-shaped clamping blocks 605 are fixed on the top of the two connecting blocks B604 respectively; wherein, a clamping opening is formed between the tops of the two arc-shaped clamping blocks 605, and the end of the U-shaped frame 4 is clamped between the two arc-shaped clamping blocks 605 from the clamping opening, and the two arc-shaped clamping blocks 605 are clamped and matched with the end of the U-shaped frame 4.

[0037] The utility model has the advantages of positioning the pull tab 5 after being pulled by positioning the U-shaped frame 4 by setting a fixing block 601, a connecting block A602, an elastic sheet 603, a connecting block B604 and an arc-shaped clamping block 605, so that the pull tab 5 remains stable relative to the chain head 3, which is convenient for the next pulling. It solves the problem that the pull tab 5 is in an unfixed state and the pull tab 5 is flipped and stuck, resulting in the need to adjust the pull tab 5 when pulling the slider, causing troublesome operation.

[0038] Specifically, the elastic sheet 603 adopts a V-shaped structural design, and the open ends of the two elastic sheets 603 are opposite to each other. When the arc-shaped block 605 is squeezed, the V-shaped elastic sheet 603 can be squeezed without affecting the squeezing of the arc-shaped block 605. At the same time, the end of the U-shaped frame 4 is inserted between the two arc-shaped blocks 605, and the arc-shaped block 605 rebounds to clamp the positioning U-shaped frame 4.

[0039] The two elastic sheets 603 are provided with vertical sections at opposite ends, and a certain support capacity is provided by the vertical sections of the elastic sheets 603. A gap is left between the two elastic sheets 603 at opposite ends, so as not to hinder the two elastic sheets 603 from being squeezed and deformed.

[0040] Working principle: When the pull tab 5 drives the chain head 3 to be pulled, the pull tab 5 rotates relative to the chain head 3 and is relatively parallel. At this time, the end of the U-shaped frame 4 is inserted between the two arc-shaped blocks 605 from the clamping opening. When the arc-shaped blocks 605 are squeezed, the V-shaped elastic sheet 603 can be squeezed, and the end of the U-shaped frame 4 is inserted between the two arc-shaped blocks 605, and then the arc-shaped blocks 605 rebound to clamp the positioning U-shaped frame 4, and the U-shaped frame 4 is positioned, thereby positioning the pull tab 5, so that the pull tab 5 remains stable relative to the chain head 3. When the chain head 3 is pulled again, the pull tab 5 is directly pulled out, and the end of the U-shaped frame 4 is pulled out from between the two arc-shaped blocks 605.

[0041] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
