[0027] As Figure 1 , Figure 2 , Figure 3 , Figure 4 Embodiment 1 as shown in the drawings:
[0028] The left end of the upper layer of the lower block 1 extends rearwardly to form an upper layer tail portion 11 (defined as the direction away from the chain belt), and the upper layer tail portion 11 is fixedly provided with a rightwardly extending elastic crossbar 13, and a convex portion 14 extends downwardly from the middle portion of the crossbar 13. The left end of the lower layer of the block 1 extends rearwardly to form a lower layer tail portion 12.
[0029] The lower block 1 and the upper layer tail portion 11, the crossbar 13, the convex portion 14, and the lower layer tail portion 12 are made of plastic with elasticity by one-time injection molding. When the lower block 1 is a metal die casting, the upper layer tail portion 11 is additionally provided with a hole for facilitating the injection molding of the plastic crossbar 13, which can be fixed by point gluing or the crossbar 13 is injection molded on the lower block 1 in a manner of overmolding, so that the crossbar 13 has elasticity.
[0030] The rear end of the pick 2 extends rearwardly to form an elastic pick tail portion 21, the pick tail portion 21 has an upwardly facing recessed portion 23 and an end protrusion 22 adjacent to the recessed portion 23, and the upper surface of the end protrusion 22 of the pick tail portion 21 is provided with an inclined surface 221 facing obliquely upwardly.
[0031] The skewer 2 and the skewer tail 21 are made of elastic plastic by one-time injection molding. When the skewer 2 is a metal die casting, the skewer 2 is additionally provided with a skew hole to facilitate the injection molding of the skewer tail 21 which can be glued and inserted for fixation, or the skewer tail 21 is made by overmolding on the skewer 2 to make the skewer tail 21 elastic.
[0032] The lower stopper 1 is sewn and fixed on the cloth 41 of the left zipper (or on the box body), and the left chain tape 51 of the left zipper is also sewn and fixed on the cloth 41 of the left zipper.
[0033] The puller 3 is combined with the left chain tape 51 and is located above the lower stopper 1.
[0034] The skewer 2 is sewn and fixed on the cloth 42 of the right zipper (or on the box cover), and the right chain tape 52 of the right zipper is also sewn and fixed on the cloth 42 of the right zipper.
[0035] In use:
[0036] The skewer 2 is inserted into the puller cavity of the puller 3 and reaches the bottom of the lower stopper 1. If the skewer 2 is continuously inserted, the end protrusion 22 of the skewer tail 21 will push against the protruding part 14 of the horizontal rod 13 of the lower stopper 1. Since the skewer tail 21 and the horizontal rod 13 are elastic, they will be deformed. The skewer tail 21 will go down, and the horizontal rod 13 will go up. After the end protrusion 22 passes through the protruding part 14, the skewer tail 21 and the horizontal rod 13 will be elastically deformed and reset, i.e., bounce and engage. The protruding part 14 is clamped in the recessed part 23 of the skewer tail 21. The lower stopper 1 blocks the skewer 22, and the skewer 2 cannot be continuously inserted.
[0037] In this way, the recessed part 23 of the skewer tail 21 and the protruding part 14 of the horizontal rod 13 form a "clamping" function with a concave-convex structure, forming a "horizontal clamping engagement". The skewer 2 and the lower stopper 1 are relatively clamped and fixed, forming positioning. At this time, the left and right chain teeth are at the correct waiting engagement position, and the left chain tape 61 and the right chain tape 62 enter the puller 3.
[0038] Then, the puller 3 is held with one hand to perform the engagement opening and pulling action. Since the skewer 2 and the lower stopper 1 are relatively clamped and fixed, they will not be separated. By pulling the puller, the left chain tape 51 and the right chain tape 52 can be combined.
[0039] When it is necessary to separate, after the puller 3 is pulled downward to separate the teeth, the puller 3 pushes against the lower stopper 1, and the elastic skewer tail 21 is bent downward. The protruding part 14 is separated from the recessed part 23, the skewer 2 is reset, i.e., bounces out, and the skewer 2 is pulled forward to separate the skewer 2 and the lower stopper 1.
[0040] In this way, the opening zipper can be quickly, stably, accurately, simply and quickly operated.
[0041] The slope 221 of the end protrusion 22 is designed to make it easier for the skewer tail 21 to deform downward and pass through the protrusion 14 when the slope 221 is pressed against the protrusion 14.
[0042] In other embodiments, the skewer extends out of the upper and lower elastic rods, the lower block is provided with upper and lower tails, the upper tail is provided with a downward protrusion corresponding to the upward recess of the upper elastic rod, and the lower tail is provided with an upward protrusion corresponding to the downward recess of the lower elastic rod. That is, the skewer and the lower block can also be designed with upper and lower double recesses and double protrusions, forming a double concave-convex clamping structure on the upper and lower surfaces.
[0043] As shown in Embodiment 2: Figure 5
[0044] In addition, the lower block 2 can also be additionally designed to extend rearward an arc-shaped (inverted type) elastic rod 15, the recess of the rod 15 faces forward, and the right end of the rod 15 extends out a protrusion 16 to the right.
[0045] The rear end of the skewer 2 extends rearward an elastic skewer tail 21', the skewer tail 21' has a leftward recess 23' and an end protrusion 22' adjacent to the recess 23', and the upper surface of the end protrusion 22' of the skewer tail 21' is provided with a leftward and rearward slope 221'.
[0046] In use:
[0047] When the skewer 2 is inserted into the puller cavity of the puller 3 and reaches the bottom of the lower block 1, and continues to be inserted, the end protrusion 22' of the skewer tail 21' of the skewer 2 is pressed against the protrusion 16 extending out to the right of the right end of the rod 15 of the lower block 1. Due to the elasticity of the skewer tail 21' and the rod 15, deformation occurs, the skewer tail 21' moves to the right and the rod 15 moves to the left, and after the end protrusion 22' passes through the protrusion 16, the skewer tail 21' and the rod 15 elastically deform and reset, that is, bounce and clasp. The protrusion 16 is clamped in the recess 23' of the skewer tail 21', the lower block 1 blocks the skewer 22, and the skewer 2 cannot be continuously inserted.
[0048] In this way, the recess 23' of the skewer tail 21' and the protrusion 16 of the rod 15 form a "clamping" function in a concave-convex structure, forming a "longitudinal clamping" function, and the skewer 2 and the lower block 1 are relatively clamped and fixed, forming positioning. At this time, the left and right chain teeth are in the correct clasp position, and the left and right chain belts 61 and 62 enter the puller 3
[0049] Then, the puller 3 is held with one hand to perform a clasp opening and pulling action. Since the skewer 2 and the lower block 1 are relatively clamped and fixed, they will not be separated, and the puller can be pulled to combine the left and right chain belts 51 and 52.
[0050] When the puller 3 is pulled downward, the puller 3 is pressed against the lower stopper 1, the elastic rod 15 is pressed downward or leftward, the convex part 16 is separated from the concave part 23', the tine 2 is reset, i.e. is bounced out, the tine 2 is pulled forward, and the tine 2 and the lower stopper 1 are separated.
[0051] The open zipper can be operated fast, stably, accurately and simply.
[0052] The slope 221' of the end convex part 22' is designed to make the tine tail 21' deform rightward and pass through the convex part 16 when the slope 221' is pressed against the convex part 16.
