The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.
[0023] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.
[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0025] See also Figures 1 to 5 , is a split slider structure according to an embodiment of the present invention, comprising a slider body 10 and a pull tab 20 connected to the slider body 10 .
[0026] The slider body 10 includes a lower wing plate 11 and an upper wing plate 12 that are spaced apart, a guide column 13 connected between the lower wing plate 11 and the upper wing plate 12, a slider trunk 14 that bends and extends downward from the top of the upper wing plate 12, two limiting columns 15 that are spaced apart in the middle of the upper wing plate 12, and a positioning pin 16 connected to the bottom end of the upper wing plate 12; the positioning pin 16 is used to match and buckle the slider trunk 14 to achieve the closure of the slider trunk 14, and at this time, the two limiting columns 15 are located on the inner side of the slider trunk 14.
[0027] Specifically, an avoidance position 141 is provided on the inner wall of the top of the slider trunk 14, and the avoidance position 141 is used to accommodate two limiting columns 15 to ensure that the slider trunk 14 will not interfere with the limiting columns 15 when it is closed. A pressing block 142 is convexly provided on the inner wall of the slider trunk 14 corresponding to the avoidance position 141, and the opposite ends of the pressing block 142 correspond to a limiting column 15 respectively, so that the area surrounded by the upper wing plate 12, the two limiting columns 15 and the pressing block 142 can be used to accommodate the pull tab 20, and jointly define the position of the pull tab 20. A positioning pin hole 143 is provided on the inner wall of the bottom end of the slider trunk 14, and the positioning pin hole 143 is matched and buckled with the positioning pin 16 to realize the closure of the slider trunk 14, and then complete the connection of the pull tab 20.
[0028] In this embodiment, the positioning pin 16 is arranged in a wedge shape, and the positioning pin hole 143 is arranged in a wedge shape.
[0029] The top of the pull tab 20 is provided with an opening 21, so that the top of the pull tab 20 forms a hanging rod 22; the hanging rod 22 is located inside the avoidance position 141, so that the pull tab 20 and the slider body 10 are connected to each other. Specifically, the hanging rod 22 is correspondingly accommodated in the area surrounded by the upper wing plate 12, the two limiting columns 15 and the pressing block 142. Among them, the bottom end of one limiting column 15 and the slider trunk 14 are both penetrated with an opening 21.
[0030] During assembly, first lift the slider trunk 14, place the hanging rod 22 between the two limit posts 15, and then align the bottom end of the slider trunk 14 with the positioning pin 16, and press hard. Since the slider body 10 is a resin slider body made of resin material, it has a certain elasticity, so the positioning pin 16 can squeeze the opposite side walls of the positioning pin hole 143 and enter the interior of the positioning pin hole 143 to achieve buckling, so as to complete the assembly of the slider body 10 and the pull tab 20. In actual use, the slider body 10 and the pull tab 20 are split designs and can be produced separately. By matching the slider body 10 with different pull tabs 20, the production of different zippers can be realized, which effectively improves the flexibility of matching and greatly reduces the production cost.
[0031] In this embodiment, combined with Figure 4 and Figure 5 It is understood that the distance between the two limit columns 15 is smaller than the height D1 of the hanging rod 22, and the distance between the pressure block 142 and the upper wing plate 12 is smaller than the height D1 of the hanging rod 22, so that the hanging rod 22 is always firmly clamped between the two limit columns 15 or between the pressure block 142 and the upper wing plate 12, effectively preventing the pull tab 20 from shaking. At the same time, when the pull tab 20 rotates, the friction between the hanging rod 22 and other parts can also be used to improve the damping feel of the pull tab 20 when it rotates.
[0032] In this embodiment, a first concave position is provided on the inner side of each limiting column 15 , and a second concave position is provided on the inner side of the pressing block 142 . Both the second concave position and the first concave position are used to better contact the hanging rod 22 to prevent the pull tab 20 from shaking.
[0033] The above-mentioned split slider structure has a simple structure and is easy to use. The slider body 10 and the pull tab 20 are split designs and can be produced separately. The positioning pin 16 can be easily squeezed into the positioning pin hole 143 to achieve the closure of the slider trunk 14, completing the rapid assembly of the slider body 10 and the pull tab 20, effectively improving the flexibility of matching and greatly reducing the production cost.
[0034] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0035] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
