Description

double chain zipper

technical field

The utility model relates to a slide fastener, in particular to a double chain slide fastener. the

Background technique

Zippers are commonly used connecting components in clothing such as clothes, trousers, shoes, and hats. The zipper is composed of a zipper head and left and right racks arranged on the cloth strip; pull the zipper head to make the teeth on the left and right racks mesh with each other and form a whole, or vice versa to separate them. Traditional zippers are mostly single-chain structures, that is, one zipper puller is only connected to a pair of racks. For double-layer garments, such as garments composed of inner denier and outer cover, two zippers are generally set inside and outside, and two operations are required, that is, pulling the inner and outer zipper pulls respectively to make the inner denier and outer cover open/close. Separately, it is more inconvenient to wear. the

Contents of the invention

The purpose of this utility model is to provide a double-chain zipper, which combines the inner and outer zippers into one, and one zipper puller can simultaneously complete the opening/closing operations of the two zippers. the

The double-chain zipper is provided with a toothed rack, a zipper puller and a handle which can be engaged left and right. The zipper head is provided with a groove for inserting the left and right racks. There are two front and rear groove rails separated by spacers inside the zipper slider. The two pairs of overlapping racks are connected to the front and rear groove rails of the same zipper slider. Simultaneously unravel separately. the

More than one zipper slider is connected to the length of the two pairs of racks overlapping front and rear, and each zipper slider is arranged in the same direction or opposite to each other on different length sections. the

A handle is provided at the front and rear of the slider. the

The double-chain slide fastener of the utility model can use one slide fastener head to control two slide fasteners at the same time, and two slide fastener pullers in the same direction or opposite directions can be arranged in sections according to needs for longer slide fasteners. The double-chain zipper is used for garments that contain two layers of separation and need to be opened and closed separately, so that the inner and outer layers can be opened/closed at one time, which simplifies the structure and is convenient to use. the

Detailed ways

The structure of the double-chain zipper is shown in Fig. 1, and a zipper head 3 is connected with two overlapping zippers at the same time to form a double-chain zipper. Fig. 1 shows that pulling the slider 3 upwards can respectively make a pair of left and right racks 5-1 on the front slide fastener 5 and a pair of left and right racks 6-1 on the back slide fastener synchronously engage. The slide fastener of the utility model is used for clothing with an inner and outer double-layer structure or partly with a double-layer structure, and can complete the opening and closing of the inner and outer layers at one time. the

Fig. 2, Fig. 3 and Fig. 4 show the structure of the zipper puller 3 of this double chain zipper, Fig. 1 is the front view of this zipper puller 3, it can be seen that it has no difference with the front structure of the common zipper puller. the

Fig. 3 and Fig. 4 are respectively the left view and the bottom view of the zipper puller 3, as can be seen from the two figures, the zipper puller 3 is provided with a spacer 2, which divides the zipper puller 3 into front and rear groove rails , the front groove rail 3-1 is inserted for the front rack 5-1, and the rear groove rail 3-2 is inserted for the rear rack 6-1. Because the zipper slider 3 needs to include two front and rear groove rails 3-1, 3-2, and insert the front and rear two racks 5-1, 6-1 at the same time, so the distance between the front and rear two pieces of the zipper slider 3 is about the same as that of an ordinary zipper slider. 2 times. the

A handle 1 is respectively arranged at the front and rear of the slider 3, and is respectively connected to the handle mounting buckles 4. the
