Abstract
Description
Technical Field
[0001] The invention relates to the field of zippers, in particular to a zipper end structure. Background Art
[0002] like Figure 1 , Figure 2 The prior art shown in the figure generally has a closed zipper with an upper stop and a lower stop at the end of a general size zipper, or an open zipper with an upper stop, a lower stop, and a pin, or a post-processing process with an upper stop and a double-open pin and a fixed pin to meet the zipper application needs of ready-made clothes, bags and luggage. The finished product is turned into a semi-finished product, and then the end user can DIY the product by zipping it, which is a product that is both beautiful and cheap.
[0003] As mentioned above, closed, open and double-open zippers are basically constrained by the fact that the top stop, bottom stop pin, and bottom stop are all fixed components. Therefore, closed zippers cannot be completely disassembled, and although open zippers can be disassembled, the tooth pitch of the chain belt is not completely consistent. After the same length but different batches of zipper tooth belts are combined, the same length but different number of teeth often appear, resulting in a difference in the top stop position with high and low teeth at one end, or the zipper is curved due to different compensation when being sewn, resulting in an imperfect appearance. Summary of the invention
[0004] The present invention provides a multifunctional hand-guided blocking assembly at the end of a zipper, the purpose of which is to solve the shortcomings of the prior art. The user can assemble and adjust the zipper by himself, solving the defect that the traditional zippers cannot adapt to the position difference when they are assembled together.
[0005] The technical solution adopted by the present invention to solve the technical problem is:
[0006] A multifunctional hand-guided blocking assembly at the end of a zipper, characterized in that:
[0007] The ends of the left zipper and the right zipper are respectively connected to corresponding TPU rubber strip handles, and the rubber strip handles are connected to the complete teeth at the end of the zipper chain;
[0008] The width and thickness of the rubber strip guide are smaller than the corresponding tooth width and thickness of the chain belt;
[0009] The rubber strip guide of the zipper left by the slider is provided with an oblique groove, and the thickness of the oblique groove is smaller than the cloth seam gap on the cavity of the slider;
[0010] The slider is inserted into the slot obliquely and then slides into the zipper;
[0011] The rubber strip guide with the oblique groove is provided with a lower stop, the lower stop and the chain belt are located on both sides of the oblique groove, the lower stop is provided with a through hole in the same direction of the chain teeth toward the opposite side, and the rubber strip guide on the opposite side passes through the lower stop.
[0012] The fabric end edges of the remaining fabric at the ends of the left zipper and the right zipper are covered with the covering section to prevent the warp and weft yarns of the fabric tape from becoming loose and tattered.
[0013] The covering section is a TPU body integrated with the corresponding rubber strip guide, or a clamping metal sheet obtained by a pre-die-casting or stamping process.
[0014] The distance from the lower stop to the oblique groove is equal to the length from the waist of the slider to the closed end.
[0015] The surface of the rubber strip handle with a lower stop is designed with scale marks as memory position numbers for adjusting the tooth position.
[0016] There is a through hole on one side of the lower gear, and the upper and lower ends of the other side extend out to the side with an upper buckle piece and a lower buckle piece respectively, forming a clamping opening between the upper buckle piece and the lower buckle piece. After the rubber strip guide with the oblique groove is inserted into the clamping opening, the upper buckle piece and the lower buckle piece clamp and fix the rubber strip guide with the oblique groove.
[0017] The ends of the upper buckle piece and the lower buckle piece are provided with hook bodies, and the ends of the upper buckle piece and the lower buckle piece are provided with an opening.
[0018] When the zipper is a double-layer tooth anti-riot zipper, the upper and lower center core wires at the end are inserted into the corresponding clamping openings and through holes of the lower block and clamped.
[0019] The present invention is beneficial in that:
[0020] The present invention is to inject two elongated rubber strips of semi-soft plastic such as TPU at the ends of the size zipper, respectively, to connect the end teeth of the left and right chain teeth, so that the semi-soft rubber strips can be easily inserted into the slider to form the engaging teeth. Furthermore, one side of the two rubber strips is selected through the injection mold design, and an oblique groove with a thickness lower than the gap of the slider cloth seam is added near the end tail teeth, so that the slider can be inserted into the oblique groove in the forward or reverse direction. Then, on the rubber strip extending outward from the oblique groove, a similar open lower block shape is set at a distance from the oblique groove that is slightly equal to the length from the waist of the slider to the closed end, and the opposite side of the rubber strip has a square hole, as if the opposite rubber strip guide (semi-soft) can be inserted and penetrated. This design can achieve that when the slider is bent and obliquely inserted into the single-side chain belt through the oblique groove, the slider is retreated to the lower block, and then the opposite rubber strip guide is first inserted into the slider cavity and then penetrated through the lower block, so that the left and right guides are close together and held to pull the slider to engage the teeth to form a complete finished product, and then check whether the finished product is flat or not, and adjust the balance correction of the teeth by several tooth pitches before and after to make the finished product look perfect. This design can be combined by zipper teeth for mutual folding and splicing, and this function can be improved in response to the lack of position difference that traditional zippers cannot adapt to each other. After disassembly, the slider is blocked by the lower stopper so that it will not fall out and be lost easily. The semi-flexible design of this slider has the advantages of closed and open or double opening in operation, and the extended length of the rubber strip can solve the height difference of the left and right single-sided chains with the same length but different numbers of teeth, and achieve perfect correction and adjustment in the use of the finished product.

[0031] In order to more clearly illustrate the technical solution of the present invention, the following will briefly introduce the drawings required for the description. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other embodiments can be obtained based on these drawings without creative work. In order to facilitate the understanding of the present invention, the present invention is described in more detail below in combination with the drawings and specific embodiments.

In addition, the terms "first", "second", "third", etc., etc. are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.
[0033] like Figure 3 As shown:
[0034] The original method of cutting and threading a 100-yard zipper can be changed to first automatically read the teeth and align a 0.8-1.0 cm alignment hole, and then use this gap as a detection signal for fully automatic cutting and smooth flow operation.
[0035] After the fixed-size zipper is cut, half of the remaining fabric (0.4-0.5 cm) is retained at the end of the left zipper 11, and the TPU is coated with the left covering section 31 of the left rubber strip handle 41 formed by semi-soft plastic injection molding. The left rubber strip handle 41 is connected to the unfinished teeth of the left chain belt 21. The TPU body of the left covering section 31 can cover the fabric edge of the left zipper 11 to prevent the warp and weft yarns of the fabric belt from being loose and rotten. Half of the remaining fabric (0.4-0.5 cm) is retained at the end of the right zipper 12, and the TPU is coated with the right covering section 32 of the right rubber strip handle 42 formed by semi-soft plastic injection molding. The right rubber strip handle 42 is connected to the unfinished teeth of the right chain belt 22. The TPU body of the right covering section 32 can cover the fabric edge of the right zipper 12 to prevent the warp and weft yarns of the fabric belt from being loose and rotten.
[0036] In the above embodiments, the left rubber strip guide 41 and the left covering section 31 are integrated, and the right rubber strip guide 42 and the right covering section 32 are integrated.
[0037] In another embodiment, the left covering section 31 and the right covering section 32 can be clamping metal sheets obtained by a pre-die-casting or stamping process, which clamp the cloth end edges of the left zipper 11 and the right zipper 12 to prevent the warp and weft yarns of the cloth tape from becoming loose and rotten. The other end of the clamping metal sheet clamps the left rubber strip handle 41 and the right rubber strip handle 42. In this way, the production process of the rubber strip handles can be more standardized, giving play to greater flexibility in supply and demand.
[0038] The width and thickness of the injection-molded left rubber strip handle 41 are limited to be slightly smaller than the tooth width of the left chain belt 21 and the thickness of the chain belt, and the width and thickness of the right rubber strip handle 42 are limited to be slightly smaller than the tooth width of the right chain belt 22 and the thickness of the chain belt, so as to facilitate smooth sliding into the slider cavity of the slider 7.
[0039] When the left zipper 11 and the right zipper 12 are opened and separated, the slider 7 is to stay on which side. Taking the left side as an example, a slanted groove 5 is provided on the left rubber strip guide 41 near the end teeth of the left chain belt 21 of the left zipper 11. The thickness of the slanted groove 5 after injection is smaller than the gap of the cloth seam on the cavity of the slider 7 (that is, the distance between the side guard plate and the lower bottom plate), so that the slider 7 can penetrate through the slanted groove 5 and then slide into the single-side chain tooth belt. When the slider 7 moves backward, it will not naturally come out of the slanted groove 5, and must be manually taken out.
[0040] like Figure 3 , Figure 4 , Figure 5 As shown:
[0041] At the same time, a lower stopper 6 similar to an opening is provided at a position where the left rubber strip guide 41 of the oblique groove 5 extends an appropriate distance, which is slightly equal to the length from the waist of the slider 7 to the closed end. The lower stopper 6 and the left chain belt 21 are located on both sides of the oblique groove 5. The lower stopper 6 covers the left rubber strip guide 41 itself, and a through hole 61 is provided in the same chain tooth direction toward the opposite side. The width and height of the through hole 61 can accommodate the right rubber strip guide 42 on the opposite side, that is, the hole height and hole width of the through hole 61 are slightly larger than the width and thickness of the semi-soft right rubber strip guide 42 on the opposite side, so as to facilitate easy insertion.
[0042] The lower stop 6 is a metal buckle block formed by die-casting or stamping, with a through hole 61 on one side and an upper buckle piece 62 and a lower buckle piece 63 with hooks at the ends extending laterally at the upper and lower ends of the other side, respectively. A clamping opening 64 is formed between the upper buckle piece 62 and the lower buckle piece 63, and an opening 65 is provided between the ends of the upper buckle piece 62 and the lower buckle piece 63. Since the upper buckle piece 62 and the lower buckle piece 63 are metal sheets, they have a certain elasticity, and the opening 65 allows the upper buckle piece 62 and the lower buckle piece 63 to have room for clamping.
[0043] The lower stopper 6 with the through hole 61 also has the conventional upper and lower stopper function. When the left and right chains 21 and 22 are engaged, it is the lower stopper function, and when the left and right chains 21 and 22 are separated, the semi-flexible right rubber strip guide 42 on the opposite side can be pulled out like a general opening pin to complete the separation state, so it has the same function as the opening component.
[0044] After the clamping opening 64 of the lower stop 6 is inserted into the left rubber strip guide 41 , a proper position is selected, and the left rubber strip guide 41 is clamped and fixed by the upper buckle piece 62 and the lower buckle piece 63 .
[0045] The method is to first tear open the left and right sides of the zipper and sew them to the fabric or the box shell respectively, then insert the slider 7 into the zipper and adjust it to achieve a perfect balance in the finished product assembly, and then clamp and fix the left rubber strip handle 41, and make the two opposing sliders 7 have a lower stop 6 on a single single-sided chain belt to prevent them from slipping out, while the right rubber strip handle 42 on the other side can pass through the slider 7 and then through the through hole 61 of the lower stop 6 to achieve the function of both opening and closing.
[0046] The surface of the left rubber strip guide 41 provided with the lower stop 6 can be designed with a concave mark 8 with scale (1234 or abcd) as a memory position number for adjusting the tooth position.
[0047] The actual operation sequence is: Figure 6 As shown, first align the cloth seam gap of the slider 7 with the oblique groove 5 on the left rubber strip guide 41 (the left rubber strip guide 41 can be bent) and insert the slider 7 first.
[0048] like Figure 7As shown, the slider 7 is retracted to the lower stop 6 and stopped, and then the right rubber strip guide 42 on the opposite side is first inserted into the inner cavity of the slider 7 and further penetrates the through hole 61 of the lower stop 6, and then the left chain belt 21 and the right chain belt 22 are selected as the corresponding position through the slider 7 to engage the teeth, just like the operation of a general open zipper, but the present design adds the following Figure 8 , Fig. 9 As shown, the left and right side engagement positions can be adjusted to make balance corrections for finished boxes or clothes.
[0049] The structural innovation of the injection-molded rubber strip guide of the present invention has the blocking function of both traditional closed and open zippers and adds adjustable teeth at the front and rear positions that can be sewn to eliminate sewing slippage, making the appearance smooth and perfect, which is the main innovative feature.
[0050] The present invention can achieve the end product of the processing design of mutual splicing and interchangeability in the application of zippers, and aims to save tariffs and facilitate the storage of zippers when not in use.
[0051] For the double-layer tooth anti-riot zipper, the upper and lower center core wires on the end surplus cloth can be directly inserted into the corresponding clamping openings 64 and through holes 61 of the lower stop 6 of the metal bundle block after sizing, and then clamped, that is, pressed and fixed in place.
