[0037] The following disclosure provides many different embodiments or examples for implementing different solutions of the present invention.

[0038] Refer to the attached Figure 1 To Attachment Fig. 9 As shown, a zipper includes a slider, a zipper belt, an I-shaped code 5 and chain teeth, wherein the chain teeth include a tooth body 1, a head 2, a mounting portion 3 and a limiting portion 4, wherein the head 2 is arranged at one end of the tooth body 1 for engaging with the opposite chain teeth, including a trapezoidal convex portion 21 located in the middle position and having a trapezoidal shape and guide slopes 22 respectively arranged on both sides of the convex portion 21, so that when the chain teeth on both sides are engaged with each other, it is convenient to insert them into the gap between the adjacent chain teeth on the opposite side through the guide slopes 22, and the guide slopes 22 of the adjacent chain teeth are arranged to be parallel to each other, which can further improve the smoothness of the engagement of the two tooth chains.

[0039] In one embodiment of the present invention, the spacing between adjacent chain teeth on the same side is set to be smaller than the thickness of the protrusion 21, and the thickness of the protrusion 21 gradually decreases from one end away from the mounting portion 3 to the other end. When the two zipper chain straps are meshed by the pull head, it can be avoided that the limiting groove 41 is difficult to form a limit with the head 2. The corresponding chain teeth on both sides can be squeezed and meshed by the pull head under the action of external force to prevent cracking.

[0040] In one embodiment of the present invention, the I-code 5 includes a left half 51 and a right half 52 that can be buckled with the left half 51. The outer sides of the left half 51 and the right half 52 are respectively provided with a first groove 6 and a second groove 7 for installing on the zipper chain. After the right half 52 and the left half 51 are buckled together, an I-code body is formed. The width and height of the I-code body are smaller than the inner 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 with each other.

[0041] In one embodiment of the present invention, a first recess 511 and a first protrusion 512 for buckling with the right half 52 are provided on one side of the left half 51, and a second recess 521 and a second protrusion 522 which can be buckled with the first recess 511 and the first protrusion 512 respectively are provided on the side of the right half 52 away from the second recess 7, and a limit plate 8 is transversely provided in the first recess 511, and a card slot 9 is provided on the right half 52, so that after the left half 51 and the right half 52 are buckled, the I-code body part can be prevented from being accidentally disconnected laterally, thereby ensuring the overall safety of the zipper.

[0042] In one embodiment of the present invention, the width and height of the chain teeth are set to be smaller than the width and height of the single-sided channel in the slider, and the slider can be used to make the opposite side chain teeth engage with each other. The chain teeth are made of zinc alloy, which reduces costs while improving the texture of the zipper. Further, 360° polishing without dead ends is adopted to make the product smoother and not damage the surface of clothes and human skin.

[0043] In one embodiment of the present invention, the mounting portion 3 is arranged at the other end of the tooth body 1 for connecting with the zipper chain and ensuring that the chain teeth are firmly installed. The mounting portion 3 includes two movable buckle teeth 31 and a buckle groove arranged between the two buckle teeth 31. One side of the buckle groove is provided with an opening 32 for the zipper chain to enter. The angle between the two buckle teeth 31 can be adjusted by the zipper particle tooth assembly machine to adjust the size of the opening 32, so as to facilitate installation on the corresponding zipper chain.

[0044] The chain teeth adopt a single tooth implantation process. The specific operation process of the zipper particle tooth assembly machine is as follows: turn on the conveying device to allow the chain teeth to enter the feeding structure in an orderly manner, and ensure that the chain teeth fall into the chain tooth grooves, turn on the tooth implantation mechanism and the towing mechanism, rotate the main shaft, and the cam pushes the slider to move. The slider drives the chain teeth in the chain tooth groove to move forward to the zipper chain. At the same time, the slider pushes the left and right clamping feet to move to both sides of the chain teeth and clamp the chain teeth; the main shaft rotates one circle, driving the rotation of the eccentric wheel, thereby pulling the connecting rod downward. The downward movement of the connecting rod causes the slider to slide in the through groove, driving the towing active wheel shaft to rotate a certain angle, so that the zipper chain moves one tooth position, and then the chain teeth are clamped to the zipper chain in sequence.

[0045] In one embodiment of the present invention, protrusions 33 are respectively provided on the inner walls of the two locking teeth 31. When the chain teeth are installed on the zipper chain, the corresponding protrusions 33 can be driven to move by the locking teeth 31, so that the protrusions 33 are embedded in the zipper chain, further improving the stability of the chain teeth after installation.

[0046] In one embodiment of the present invention, the protrusions 33 are all located in the buckle grooves, and their shapes can be spike-shaped or other shapes that can easily fit and engage with the zipper chain on the corresponding side. The protrusions on each side are respectively arranged along the length direction of the inner wall of the buckle tooth 31, and can be arranged in a straight line or staggered, which improves the firmness of the installation when engaging and prevents it from falling off.

[0047] In one embodiment of the present invention, the limiting portion 4 is located between the head 2 and the mounting portion 3, and the limiting portion 4 includes limiting grooves 41 respectively arranged on both sides of the tooth body 1 for accommodating the opposite side chain teeth, and a limiting surface 42 arranged perpendicular to the bottom surface of the limiting groove 41, the limiting surface 42 is the bottom surface of the protrusion 21, and one side edge of the limiting groove 41 close to the limiting surface 42 can coincide with the limiting surface 42 or maintain a certain distance without affecting the insertion of the opposite side head 2.

[0048] Therefore, the head 2 can be fixed in the corresponding limiting groove 41 under the action of the pull head, and the limiting surface 42 can prevent the chain teeth from being laterally displaced under the action of external force, thereby improving the overall strength and avoiding disconnection from the middle position or tooth breakage after the two tooth chains are connected.

[0049] In one embodiment of the present invention, the depth of the limiting groove 41 is set to be greater than the height of the limiting surface 42, so that when the two fastener chains are engaged, the head 2 on the same side can be completely clamped by the upper and lower chain teeth, and the limiting surfaces 42 can be completely inserted into the corresponding limiting grooves 41, respectively, to further ensure the stability of the fastener chains after engagement and improve the overall strength.

[0050] As defined herein, the term "length direction" or "length" refers to the direction in which the slider moves along the fastener stringer. In addition, the direction from the front surface of the fastener stringer toward the rear surface, which is orthogonal to the length direction, is defined as "lateral direction" or "width direction".

[0051] In one embodiment of the present invention, the production process of the zipper comprises the following steps:

[0052] 1) Prepare multiple chain teeth through die-casting process, perform surface treatment on the chain teeth, i.e. 360° polishing without dead angles, and prepare multiple chain teeth of different colors through electroplating process according to customer needs, and produce chain teeth of multiple different colors for backup, and then select the corresponding color according to needs;

[0053] 2) For the single chain teeth that do not meet the quality requirements, return to step 1) for re-preparation and put them into the feeding mechanism to wait for the subsequent tooth implantation work of the zipper particle tooth assembly machine;

[0054] 3) Adjust the angle between the two buckle teeth 31 to ensure that the size of the opening 32 is convenient for the side of the zipper chain to enter, and install the multiple chain teeth in step 1) on the zipper chain in sequence according to the preset intervals through the zipper particle tooth assembly machine to ensure that the protrusion 33 is embedded in the corresponding zipper chain (the preset interval is specifically 0.6-1mm):

[0055] 4) Assemble the slider onto the zipper with the chain teeth installed, and pull it up along the length of the zipper to test the engagement effect.

[0056] The surface treatment of multiple chain teeth in step 1) is carried out by adopting a true electroplating process, which can reduce pollution and be more in line with environmental protection requirements. At the same time, a variety of electroplated color teeth can be produced and installed according to customer needs, thereby achieving diversified matching of clothes.

[0057] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
