[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] The core of the utility model is to provide a post-assembly pull tab assembly, which provides a notch on the first hole of the pull tab so that the handle can enter the first hole from the notch, thereby eliminating the size requirements for the first hole and the tail end of the handle, thereby ensuring the size requirements and grip requirements of the pull tab assembly.

[0039] Another core of the present invention is to provide a zipper assembly including the above-mentioned post-assembly pull tab assembly, which has the same technical features and can achieve the same effects.

[0040] Please refer to Figures 1-9 , a post-assembly pull tab assembly, comprising:

[0041] The pull tab 2 is provided with a first hole 201, a second hole 202 and a notch 2011 communicating with the first hole 201. The second hole 202 is used for cooperating with the slider 3 for installation.

[0042] The handle 1 can enter the first hole 201 through the notch 2011 . A clamping assembly is provided on the head of the handle 1 , and the clamping assembly is used to be fixedly engaged with the first hole 201 .

[0043] Two sets of holes are provided in the pull tab 2, wherein the second hole 202 is used to connect with the slider 3, and the first hole 201 is used to connect with the handle 1. This prevents the connecting components of the slider 3 and the handle 1 in the pull tab 2 from interfering with each other, thereby ensuring the stable operation of the entire pull tab assembly.

[0044] In some embodiments, the pull tab 2 and the slider 3 are connected by riveting or by rotating a pin, the purpose of which is also to separate the connection components of the pull tab 2, the handle 1 and the slider 3 from each other, and to avoid interference between the two connection components causing instability in the operation of the pull tab assembly. The above solutions also fall within the scope of protection of this application.

[0045] Moreover, in this embodiment, a notch 2011 is provided on the side of the first hole 201, so that the handle 1 can pass through the notch 2011 and enter the first hole 201. Specifically, the handle 1 is turned over so that its thickness surface passes through the notch 2011, that is, it is only necessary to ensure that the thickness of the local cross section of the handle 1 is not greater than the width of the notch 2011. At the same time, the pull tab 2 itself is affected by the material and has a certain elastic deformation, that is, the width of the notch 2011 can change within a certain range. For example, when the handle 1 passes through, the notch 201 The two side walls of the notch 2011 are squeezed and retreated, thereby temporarily expanding the width of the notch 2011. After the handle 1 passes through, the two side walls of the notch 2011 are restored. This design ensures that the handle 1 is not restricted by the size of the head and outer end of the handle 1 when entering the first hole 201, that is, it can ensure that the tail end of the handle 1 has a larger gripping area, thereby improving the gripping experience, and there is no need to increase the cross-sectional area of ​​the first hole 201. The volume of the pull tab 2 can be reduced, and the volume of the entire pull tab assembly can be reduced, thereby ensuring its aesthetics and reducing production costs.

[0046] In some embodiments, the width of the middle portion of the handle 1 is smaller than the width of the head and tail portions, and the minimum inner diameter of the first hole 201 is no smaller than the width of the middle portion of the handle 1 , and the maximum inner diameter of the first hole 201 is no larger than the width of the handle 1 and the tail portion.

[0047] like Figure 3 and Figure 4 As shown, by limiting the width of the head, middle and tail ends of the handle 1, the handle 1 forms a structure that is narrow in the middle and wide at both ends, and the maximum inner diameter of the first hole 201 is limited, so that after the handle 1 enters the first hole 201, the two ends of the handle 1 are limited by the aperture of the first hole 201 and cannot escape therefrom, and the middle part of the handle 1 is not limited by the aperture of the first hole 201 and can rotate therein, thereby adjusting the relative angle between the plane of the handle 1 and the pull tab 2, and thus the handle 1 and the pull tab 2 can reach the correct installation position and installation angle.

[0048] In some embodiments, the thickness of the middle portion of the handle 1 is no greater than the opening width of the notch 2011 , so that the middle portion of the handle 1 can pass through the notch 2011 ;

[0049] By limiting the thickness of the middle portion of the handle 1, the handle 1 is not restricted by the width of the notch 2011 and can smoothly enter the first hole 201.

[0050] In some embodiments, restrictions are also imposed on the thickness of the head and tail ends of the handle 1, such that the thickness of the head and tail ends of the handle 1 is greater than the width of the notch 2011, thereby preventing the head and tail ends of the handle 1 from passing through the notch 2011, thereby achieving a fool-proof effect and preventing the head and tail ends of the handle 1 from entering the first hole 201 and being unable to rotate and adjust the angle.

[0051] In some embodiments, a groove channel 103 is provided in the middle of the handle 1 in a transverse direction. The thickness of the handle 1 at the groove channel 103 is not greater than the opening width of the notch 2011 , and the thickness of the pull tab 2 at the notch 2011 is not greater than the width of the groove channel 103 .

[0052] like Figure 4 As shown, by providing a groove channel 103 in the middle of the handle 1, the thickness of the handle 1 at the position of the groove channel 103 is reduced without changing the thickness of the handle 1 and ensuring the grip feel, so that the handle 1 can pass through the notch 2011 along the direction of the groove channel 103 and enter the first hole 201;

[0053] At the same time, the width of the groove channel 103 and the thickness of the pull tab 2 at the notch 2011 are limited so that there is no friction between the side walls of the two, further ensuring the smoothness of the handle 1 when passing through the notch 2011, thereby reducing the difficulty of assembly.

[0054] In some embodiments, the clamp assembly includes a clamp neck 102 and a clamp head 101 , wherein the clamp neck 102 is fixedly connected between the head of the handle 1 and the clamp head 101 ;

[0055] The handle 1 and the clamp head 101 are both provided with a limiting surface that exceeds the clamp neck 102;

[0056] The cross-sectional area of ​​the clamp head 101 is larger than the cross-sectional area of ​​the first hole 201;

[0057] like Figure 8 As shown, the clamp assembly adopts the design of the clamp neck 102 and the clamp head 101. The clamp neck 102 is clamped in the first hole 201 for radial limitation, and the handle 1 and the clamp head 101 are abutted against the surface of the pull tab 2 for axial limitation, thereby completing the fixed connection between the handle 1 and the pull tab 2, so that the two have a relatively stable connection relationship.

[0058] In some embodiments, the end of the handle 1 head away from the clamp assembly is configured as an arc surface to reduce the resistance when the handle 1 head slides relative to the side wall of the first hole 201;

[0059] like Figure 5-Figure 9 As shown, when the handle 1 and the pull tab 2 are assembled, Figure 5 As shown, the handle 1 first passes sideways through the notch 2011 and enters the first hole 201, and then, as shown in FIG. Figure 6 As shown, the handle 1 is rotated 90° along the vertical axis. Finally, as shown in FIG. Figure 7 As shown, the handle 1 is rotated 90 degrees along the horizontal axis to achieve Figure 8 In the state shown, the clamp assembly is now clamped with the first hole 201;

[0060] When the pull tab 1 rotates along the horizontal axis, the upper end surface of the head of the pull tab 1 interferes with the lower end of the side wall of the first hole 201, and by setting the upper end surface of the head of the pull tab 1 as a circular arc surface, the interference amount of the pull tab 1 and the side wall of the first hole 201 can be reduced, and the resistance during relative movement of the two can be reduced.

[0061] In some embodiments, the limiting surface of the head of the pull tab 1 and the head of the clamping piece 101 close to the limiting surface of the neck 102 of the clamping piece are both flat surfaces, and the surface of the edge of the first hole 201 for contacting the limiting surface is also a flat surface.

[0062] As shown in Figure 9 , by limiting the limiting surface and the surface of the edge of the first hole 201, the clamping piece assembly and the pull tab 2 have a relatively stable positional relationship after assembly.

[0063] In some embodiments, a limiting plate 2012 is fixedly arranged at the inner wall of the first hole 201, the thickness of the limiting plate 2012 is less than the thickness of the pull tab 2, and the two side surfaces of the limiting plate 2012 abut against the limiting surface.

[0064] As shown in Figure 9 , by setting the limiting plate 2012, the thickness of the limiting plate 2012 is less than the overall thickness of the pull tab 2, and the thickness of the clamping piece assembly can be reduced, i.e. the overall thickness of the pull tab 1 can be reduced, i.e. the overall volume of the pull tab assembly can be reduced, and the cost can be reduced.

[0065] After reducing the thickness of the clamping piece assembly, the difference in thickness between the head of the pull tab 1 and the pull tab 2 can be reduced, and the aesthetic appearance of the pull tab assembly can be further improved.

[0066] In some embodiments, the two side walls of the gap 2011 are provided with chamfers, so as to facilitate the pull tab 1 to enter the first hole 201 through the gap 2011.

[0067] By setting the chamfer, the opening of the gap 2011 outside is larger than the inside, so as to facilitate the pull tab 1 to enter the gap 2011, and the assembly difficulty is reduced and the assembly efficiency is improved.

[0068] In addition to the above-mentioned various embodiments of the post-assembly pull tab assembly, the utility model also provides a zipper assembly comprising the above-mentioned post-assembly pull tab assembly, and the structures of other parts of the zipper assembly refer to the prior art, and will not be described herein.

[0069] The various embodiments in the specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments, and the same and similar parts of each embodiment can be referred to each other.

[0070] The above describes in detail the post-assembly pull tab assembly and zipper assembly provided by the present invention. This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above examples is intended only to facilitate understanding of the method and core concept of the present invention.
