Description

Technical Field

[0001] The utility model belongs to the technical field of zippers, and more particularly relates to an I-shaped fastener and a zipper. Background Art

[0002] A zipper is a fastener consisting of two strips, each with a row of metal or plastic teeth, used to connect the edges of an opening (such as the opening of a garment or bag). A sliding piece can pull the two rows of teeth into an interlocking position to close the opening. The back locks of closed-end zippers include aluminum alloy claw locks, injection molded locks, hook locks, and I-shaped locks.

[0003] The existing I-shaped code has the same shape on both sides and is usually used on metal zippers. When sewing bags, the zipper cannot be separated, causing the zipper to always be in a closed state, which is not only inconvenient to operate but also affects sewing efficiency.

[0012] In a specific embodiment of the present invention, the left half and the right half are both made of metal.

[0013] In a specific embodiment of the present invention, the right half and the left half are buckled together to form an I-shaped code body, and the width and height of the I-shaped code body are smaller than the inner opening width of the slider, so that the slider can pass through from one end, so that the chain teeth on both sides of the other end can be interlocked.

[0014] According to a second aspect of the present invention, a zipper is provided, comprising a slider, a zipper tape, and the I-shaped code, wherein the left half and the right half are respectively fixed on corresponding zipper tapes.

[0016] One of the above technical solutions of the utility model has at least one of the following advantages or beneficial effects:

[0017] The utility model provides a left half and a right half that can be interlocked, so that the zipper belts on both sides can be sewn separately. After the sewing is completed, the left half and the right half are meshed with each other through the slider to close the zipper, which is easy to operate and can further improve the sewing efficiency. In addition, a first step is provided at one end of the left half for placing the end chain teeth on the opposite side, and a second step is provided at the right half, which can also ensure the flatness of the engagement of the chain teeth on both sides.

[0029] The following disclosure provides many different embodiments or examples for implementing different solutions of the present invention.

[0030] Refer to the attached Figure 1 To the attached Figure 5 As shown, a zipper includes a slider, a zipper strap and an I-code. The left half and the right half are respectively fixed on the corresponding zipper straps. The I-code includes a left half 1 and a right half 2 that can be buckled with the left half 1. The left half 1 and the right half 2 are both metal components. Both sides of the left half 1 and the right half 2 are respectively provided with anti-slip curved surfaces 4 for convenient operation. After the right half 2 is buckled with the left half 1, an I-code body is formed. The width and height of the I-code body are smaller than the inner opening width of the slider, so that the slider can pass through from one end, so that the chain teeth on both sides of the other end can be embedded with each other.

[0031] In one embodiment of the present invention, a first groove 11 for mounting on a zipper strap is provided on one side of the left half 1, and a second groove 21 for mounting on the zipper strap is provided on a side of the right half 2 away from the left half 1, wherein the first groove 11 is arranged along the length direction of the left half 1, and the second groove 21 is arranged along the length direction of the right half 2.

[0032] In one embodiment of the present invention, the length of the second groove 21 is set to be smaller than that of the first groove 11, so that one end of the left half 1 and the right half 2 can be kept flush, and the other end is distributed in a stepped manner, ensuring that the installation of the chain teeth is always in a reasonable layout.

[0033] In one embodiment of the present invention, one side of the left half 1 is provided with a first recess 12 and a first protrusion 13 for snapping into the right half 2, and the side of the right half 2 away from the second groove 21 is provided with a second recess 23 and a second protrusion 24 that can be snapped into the first recess 12 and the first protrusion 13 respectively, so that the left half 1 and the right half 2 can be snapped into each other.

[0034] In one embodiment of the present invention, the width and height of the left half 1 are set to be smaller than the width and height of the single-sided channel in the slider, and the width and height of the right half 2 are set to be smaller than the width and height of the single-sided channel in the slider. When the slider passes through the zipper chain, the left half 1 and the right half 2 are engaged, which is convenient for sewing the zipper chain on both sides respectively. After sewing is completed, the zipper is closed by the slider, which is not only convenient to operate but also can further improve the sewing efficiency.

[0035] In one embodiment of the present invention, a limiting device is provided between the left half 1 and the right half 2. The limiting device includes a limiting plate 31 arranged horizontally in the first recess 12 and a buckle groove 32 arranged on the right half 2. The buckle groove 32 and the limiting plate 31 are arranged correspondingly, so that after the left half 1 and the right half 2 are buckled together, the I-shaped code body part can be prevented from being accidentally disconnected horizontally, thereby ensuring the overall safety of the zipper.

[0036] In one embodiment of the present invention, the buckle groove 32 is located on the second protrusion 24, and the width of the first recess 12 is greater than the thickness of the second protrusion 24, and the width of the second recess 23 is greater than the thickness of the first protrusion 13, so as to facilitate the fast and labor-saving buckling of the left half 1 and the right half 2.

[0037] In one embodiment of the present invention, one end of the left half 1 is provided with a first step 14 for placing the end chain teeth on the opposite side, the other end of the left half 1 is corresponding to the right half 2, and the end of the right half 2 corresponding to the first step 14 is provided with a second step 22, so that after the right half 2 is buckled with the left half 1, the slider can pass through from one end so that the chain teeth on both sides of the other end are embedded with each other, and it can also ensure the embedding flatness of the chain teeth on both sides after the right half 2 is buckled with the left half 1.

[0038] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
