DETAILED DESCRIPTION

[0020] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments, so as to provide a clearer understanding of the technical concept to be protected by the present invention.

[0021] like Figures 1 to 7 As shown, a double-open-tail zipper that is easy to pull and insert comprises a cloth tape segment 1, a chain tooth strip 32, a slider, an upper stop block 4, a lower stop block 5 and a latch 6. One end of the two cloth tape segments 1 is provided with a cloth rubber segment 7. The two chain tooth strips 32 are arranged on the opposite side of the two cloth bag segments. The two upper stops are correspondingly arranged at one end of the two chain tooth strips 32 away from the cloth rubber segment 7. The lower stop block 5 is arranged at the other end of one chain tooth strip 32, and the latch 6 is arranged at the other end of the other chain tooth strip 32. The two sliders are respectively slidably connected with the two chain tooth strips 32. The lower stop block 5 comprises a lower stop pin 8, an extension strip 9 and a positioning pin 10. The lower stop pin 8 and the positioning pin 10 are connected by the extension strip 9, and the positioning pin 10 is located on the side of the lower stop pin 8 facing away from the latch 6, and a limiting track 11 is formed between the positioning pin 10 and the lower stop pin 8 for positioning the two sliders.

[0022] The working principle of the double-end zipper with easy pull and insertion of the utility model is realized by the cooperation of the tape section 1, the chain tooth strip 32, the slider, the upper stop block 4, the lower stop block 5 and the latch 6. Figures 1 to 7As shown, it should be noted that the lower stop block 5 and the latch pin 6 extend from the cloth rubber section 7 to the cloth tape section 1, which can improve the connection strength between the cloth tape section 1 and the cloth rubber section 7. First, the two sliders are moved along the chain tooth strip 32 where the lower stop block 5 is located. The lower stop block 5 is provided with a lower stop pin 8 and a positioning pin 10, and a limiting track 11 is formed between the lower stop pin 8 and the positioning pin 10. When one slider moves to the position of the lower stop block 5, the slider will first abut against the lower stop pin 8 and position the slider, and the side of the slider located on the same straight line as the lower stop block 5 will be inserted into the limiting track 11, and then the other slider is also moved to the lower stop block. 5, so that the two sliders abut against each other and the sides of the two sliders that are in the same straight line with the lower stop block 5 are both inserted into the limiting track 11, thereby aligning the two sliders, and finally the latch 6 can be inserted into the two sliders in turn to pull and close the two chain tooth strips 32. Compared with the traditional double-open zipper, the easy-to-pull and insert double-open tail zipper can position the two sliders in the limiting track 11, so that the two sliders can be prevented from shaking when they abut against each other, thereby quickly aligning the two sliders, and the latch 6 can be quickly inserted into the two sliders, thereby improving the pulling and insertion efficiency of the zipper, facilitating user use and enhancing user experience.

[0023] Specifically, a limiting protrusion 12 is provided on one side of the two upper stops facing each other, and the upper stops can block the slider by the limiting protrusion 12. Figure 1 As shown, the left and right sides of the slider are provided with retaining edges. When the slider moves to the upper stop, the limiting protrusion 12 of the upper stop can abut against the retaining edge of the slider and block the slider to prevent the slider from falling off the chain tooth bar 32, wherein the chain tooth bar 32 includes a plurality of chain teeth arranged at intervals, and the chain teeth are provided with teeth 13 on the side away from the tape segment 1, and the chain teeth are provided with inserts 14 on the left and right sides of the teeth 13, and the tooth 13 is provided with a slot 15 on the side facing away from the chain teeth, as shown in FIG. Figures 1 to 7 As shown, when the chain tooth strip 32 is pulled and closed, the teeth 13 on the chain teeth can be plugged into the insert piece 14 through the slot 15, so as to close the gap between the chain teeth and thus improve the overall closure of the zipper.

[0024] Furthermore, the two sliders are arranged on the chain tooth strip 32 facing each other, the width of the side of the two sliders facing each other is smaller than the width of the side of the two sliders facing each other, and when the two sliders are against each other, the left and right sides of the two sliders form a concave arc surface, wherein the side of the positioning pin 10 facing the lower stop pin 8 is provided with a convex limiting arc surface 16, and the curvature of the limiting arc surface 16 corresponds to the curvature of the arc surface when the two sliders are against each other, and the front side of the extension strip 9 is evenly spaced along the limiting arc surface 16 to form a plurality of fixing holes 17. Figures 1 to 7As shown, the fixing hole 17 on the extension strip 9 can improve the connection stability between the lower stop block 5 and the rubber section 7. When the two sliders move to the limiting track 11, the limiting arc surface 16 of the positioning pin 10 cooperates with the arc surface on one side of the two sliders, thereby quickly positioning the two sliders and aligning the two sliders, making it easy for the pin 6 to be inserted into the two sliders and making the zipper smooth and convenient to open and close.

[0025] Furthermore, the end of the latch pin 6 away from the tooth bar 32 is bent in a direction away from the lower stop pin 8, and the cross-sectional size of the end of the latch pin 6 away from the tooth bar 32 gradually decreases outward, and the front side of the latch pin 6 and the side facing the front side of the lower stop pin 8 are provided with a guide groove 18, such as Figures 1 to 7 As shown, the structure of the latch 6 corresponds to the structure of the slider, and the latch 6 is easier to insert into the slider. A guide strip (not shown in the figure) that cooperates with the guide groove 18 can be provided in the slider, so that the slider can move more smoothly along the latch 6 and the lower stop pin 8, thereby improving the overall insertion and pulling efficiency of the zipper.

[0026] Furthermore, the upper portion of the latch pin 6 facing the lower stop pin 8 is provided with a triangular protrusion 19, and the lower portion of the latch pin 6 facing the lower stop pin 8 is provided with a card slot 20, and the lower portion of the lower stop pin 8 facing the latch pin 6 is provided with a sealing protrusion 21 that can be inserted into the card slot 20. Figures 1 to 7 As shown, when the latch pin 6 is inserted into the slider, the sealing protrusion 21 of the lower stop pin 8 can be inserted into the slot 20 of the latch pin 6, and the triangular protrusion 19 of the latch pin 6 cooperates with the sealing protrusion 21 of the lower stop pin 8 to close the gap between the latch pin 6 and the lower stop pin 8, making it easier for the latch pin 6 and the lower stop pin 8 to align with the slider, and making it smoother for the slider to move along the latch pin 6 and the lower stop pin 8, thereby improving the overall insertion and pulling efficiency of the zipper.

[0027] The above are only specific embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
