Description

Double zipper construction that avoids the chain being split

The present invention relates to a zipper construction, in particular to a double-layer chain belt having a zipper construction with better anti-theft effect.

The general zipper will open or tie the chain after pulling the slider, which is common in the opening of clothes such as jackets and trousers. In addition, the zipper is also widely used in the case or bag of leather bags, suitcases, etc. The case or bag is closed and opened quickly and conveniently.

In order to avoid theft of the baggage by the thief during travel, the existing zippered suitcase has a zipper-locked structure around the box in addition to the zipper to close the box, so as to prevent others from opening the zipper at will. . However, according to recent news reports, consumers have found that although the suitcase has a structure that locks the slider, the general zipper has only a single layer of chain belt, and once the thief uses a ballpoint pen and other tools to open the zipper chain. It is easy to open the suitcase and steal the property without destroying the locked structure. Such a shortcoming makes the anti-theft effect of the suitcase worry, and needs further improvement.

Since the existing zipper has only a single layer of chain strap, it is set to travel At the box or the bag body, there is a disadvantage that the chain belt is easy to open and the anti-theft effect is not good; for this reason, the double-layered chain belt cooperates with the slider which can simultaneously open and bundle the double-chain belt, so that it is difficult for the thief to smash. The effect of opening the double zipper enhances the anti-theft function.

In order to achieve the above object, the present invention provides a double-layer zipper structure that avoids the chain belt being cleaved, and the structure includes: a slider having two straight-chain chain grooves at upper and lower positions of the slider. One end of each chain groove is wider and the other end is narrower, and a chain block is arranged at the center of the wider end of each chain groove, and two chain pieces are respectively opened on the two sides of the chain corresponding to each chain groove. Each of the chain piercings is a long-shaped slit and communicates with each chain groove; and two chain belts are respectively disposed in each of the chain groove grooves and are provided with two chain pieces on both sides, and the two chain pieces are respectively long strips a sheet body and an inner edge of the two chain pieces on both sides of the slider penetrate through the chain groove, and a plurality of fastener elements are combined at the inner edge of each chain, and each chain belt passes through a plurality of chains on both sides of the chain block The teeth are separated from each other, and the remaining plurality of teeth are engaged with each other.

Further, the present invention is provided with a pull tab ring on the upper surface of the slider, and a pull tab is formed, and a hole is formed at one end of the pull tab, and the loop ring is sleeved on the pull tab ring.

Furthermore, the outer edge of each of the links of the present creation is sewn to the outer edge of the other of the links on the same side.

The creation is set at the opening and closing of the box or the bag body, and the two chain belts are fixed on both sides of the opening of the box body or the bag body. When used, the slider can be pulled to make the slider head along the two chain belts at the same time. And sliding back, the two chains are made by the narrow end of each chain groove The sprocket of the belt is engaged, or the chain splicing block at the wider end of the chain groove separates the sprocket teeth on both sides to achieve the effect of closing or opening the box or the bag body.

The effect that this creation can achieve is that, because the inner and outer sides have double chain belts, when the box with the creation is locked or the bag body is closed, the thief is difficult to be in a short time or the user cannot In the case of the detection, the double-layered chain belt is simultaneously destroyed, so that the thief can prevent the thief from stealing the property in the trunk or the bag by destroying the zipper, thereby improving the safety of the zipper and the anti-theft effect.

The present invention is a two-layer zipper construction that avoids the chain being split. Referring to the preferred embodiment shown in FIGS. 1 to 4, the construction includes a zipper head 10 including a slider 11 and a pull tab 12. Two straight chain extending grooves 111 are provided at the upper and lower positions of the slider 11, and each of the chain grooves 111 has a narrow width at one end and a wide width at the other end, and each of the chain grooves 111 is wider. One end of the chain groove 111 is provided with a chain block 112 at the center of the wider end of each chain groove 111, and two chain pieces are respectively opened on the left and right sides of the upper and lower positions of the slider 11 for each chain groove 111. The port 113, each of the chain through openings 113 is a straight-shaped elongated slit, and each of the chain through openings 113 communicates with each of the chain groove 111, and a pull tab ring 114 is disposed on the upper surface of the slider 11 for pulling The sheet 12 is an elongated piece and has a hole 121 formed at one end thereof, and the sleeve 121 is movably sleeved on the tab ring 114 above the slider 11, whereby the user can pull the pull tab 12 Pulling the slider 11

The two chain belts 20 are disposed in the upper and lower positions and respectively pass through the respective chain groove 111 of the slider 11 . Each of the chain belts 20 is provided with two chain pieces 21 on both sides, and the two chain pieces 21 are respectively extended straight. The long strips of the two strips 21 are inserted into the respective strip grooves 111 by the strip openings 113 on both sides of the slider 11, and the two links 21 are located on both sides of the branch block 112. The inner edge of the chain piece 21 is combined with a plurality of fastener elements 22, each of which is separated from each other by a plurality of fastener elements 22 on both sides of the chain block 112, and the remaining plurality of fastener elements 22 are engaged with each other; Referring to FIG. 5, the present invention can further sew between the outer edges of the respective chain pieces 21 disposed at the upper and lower positions, so that the outer edges of the respective chain pieces 21 and the other side pieces 21 of the same side are outside. Edge stitching.

When the present invention is used, please refer to FIG. 4 to FIG. 6, which is to arrange the two-chain belt 20 at the opening and closing of the luggage box, the suitcase or the bag body, and when the two-chain belt 20 is combined with the foregoing box body or bag body. When the outer edges of the two chain pieces 21 of the chain belts 20 are sewn or bonded to the edge of the opening of the box body or the bag body, when the two chain belts 20 are disposed, pulling the pull tabs 12 allows the zipper heads 10 to be simultaneously The two chain belts 20 are slid, and the sprocket 22 of the two chain belts 20 is engaged by the narrow end of each of the chain belt grooves 111, or the wider end of the chain belt groove 111 is used. The chain block 112 quickly separates or separates the two chain belts 20 in a manner that separates the sprocket teeth 22 on both sides to achieve the effect of closing or opening the box or the bag.

Since the creation has a double-layered chain 20 inside and outside, when the thief wants to smash the box or the bag body by destroying the chain 20, it is difficult to simultaneously destroy the double-layered chain 20. This can lengthen the time when the thief succeeds, making the thief give up theft because of easy exposure or difficult work, and improve the security of the zipper and the function of theft prevention.
