AI Technical Summary
The depth of the existing suitcase zipper insertion pipe strip is uncertain, which makes the zipper easy to disengage, resulting in reduced meshing distance, separation of zipper teeth, separation of box shells and falling items.
A folded zipper design is adopted, wherein the first cloth tape and the second cloth tape form a dividing line by bending, the first cloth tape is inserted into the tube strip until it is fixed at the dividing line, and the width of the second cloth tape is greater than the first cloth tape, which is used to cover the tube strip and avoid a tight state.
With clear insertion boundaries and wide second cloth tape covering, the problem of uncertainty and tightness of the zipper is solved, improving the stability and aesthetics of the zipper.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of zippers, in particular to a folding edge zipper. Background Art
[0002] The existing suitcase is formed by putting an upper and a lower case shell together, and the two case shells are connected together by a zipper. The two half case shells each occupy half of the volume. In order to fix the zipper, the zipper is sewn on the edge of the half case shell. In order to fix the zipper, a tube is first inserted into the case shell, and then the tube is turned outward to insert the zipper into the tube, and finally the zipper is fixed by sewing.
[0003] However, the operator does not know how deep the zipper is inserted into the tube, and can only rely on experience to avoid the zipper from escaping from the tube. He will insert the zipper into the tube as much as possible, which will reduce the meshing distance of the zipper between the two box shells. The zipper will be in a taut state, which can easily cause the zipper teeth to separate, resulting in the box shells separating and the items falling. Summary of the invention
[0004] In view of the shortcomings of the above background technology, the purpose of the utility model is to provide a folding zipper, wherein the first fabric tape and the second fabric tape are bent differently, the first fabric tape is inserted into the tube strip and sewn together, and the second fabric tape is meshed, which will not cause the second fabric tape to be tight and cause the zipper teeth to separate.
[0005] In order to solve the above technical problems, the purpose of the utility model is achieved as follows:
[0006] A folding zipper comprises a first fabric tape, one side edge of the first fabric tape is extended and bent in the opposite direction to form a second fabric tape, the width of the second fabric tape is greater than the width of the first fabric tape; the outer edge of the second fabric tape is provided with a first zipper tooth;
[0007] Also includes a first tube strip having a U-shaped cross section;
[0008] The first cloth tape is attached to the outer surface edge of the box shell, the first tube strip is inserted into the edge of the box shell and the first cloth tape, the other side edge of the first cloth tape is inserted into the first tube strip, and the first sewing thread sews the first tube strip, the box shell and the first cloth tape to connect and fix;
[0009] The second cloth tape covers the first pipe strip.
[0010] On the basis of the above solution and as a preferred solution of the above solution: the width of the first cloth tape is equal to the U-shaped depth of the first tube strip.
[0011] On the basis of the above scheme and as a preferred scheme of the above scheme: the edge of the box shell is bent to form a folded plate, the folded plate is inserted into the first tube strip, and the bending part of the box shell forms a step; the bending parts of the first cloth belt and the second cloth belt abut against the step.
[0012] On the basis of the above solution and as a preferred solution of the above solution: the first cloth tape and the second cloth tape are integrally bent and formed.
[0013] On the basis of the above solution and as a preferred solution of the above solution: the first zipper teeth are made of plastic or metal material.
[0014] Compared with the prior art, the utility model has the following outstanding and beneficial technical effects:
[0015] Compared with the prior art, the folded edge zipper of the utility model comprises a first cloth belt and a second cloth belt folded in half, the two are bent relative to each other to form a dividing line, the first cloth belt is inserted into the first tube strip until it reaches the dividing line, indicating that the insertion is in place, and then the first sewing thread is used to sew and fix the first tube strip, the first cloth belt and the box shell. The size of the second cloth belt is larger than the width of the first cloth belt, so as to achieve the visual beauty of covering the first tube strip, and at the same time, it will not cause the second cloth belt to be in a tight state after meshing, and it is more stable.

[0020] The present invention will be further described below with reference to specific embodiments of the invention;
[0021] This embodiment provides a folded edge zipper, including a first fabric tape 01, one side edge of the first fabric tape 01 is extended and bent in the opposite direction to form a second fabric tape 02, the width of the second fabric tape 02 is greater than the width of the first fabric tape 01; the outer edge of the second fabric tape 02 is provided with a first zipper tooth 020; the first fabric tape 01 and the second fabric tape 02 are folded in half, and the bending part of the two forms a visual edge line, which is used as a boundary. The first fabric tape 01 and the second fabric tape 02 are made of a material with a certain hardness and can maintain a long-term bending state. The size of the second fabric tape 02 is wider than the first fabric tape 01, and the second fabric tape 02 will not be stretched tight when engaged.
[0022] It also includes a first tube strip 03 with a U-shaped cross section; the first tube strip 03 is made of plastic material and is used to be inserted into the edge of the box shell 04 to form a package;
[0023] The first cloth tape 01 is attached to the outer surface edge of the box shell 04, the first tube strip 03 is inserted into the edge of the box shell 04 and the first cloth tape 01, the other side edge of the first cloth tape 01 is inserted into the first tube strip 03, and the first sewing seam 05 connects and fixes the first tube strip 03, the box shell 04 and the first cloth tape 01;
[0024] The second fabric strip 02 covers the first tube strip 03. Visually, the first sewing line cannot be seen, which is more beautiful.
