Description

Technical Field

[0001] The utility model relates to the field of zippers, and in particular to a slider and a zipper for quickly repairing cracked teeth. Background Art

[0002] The slider and the chain belt are commonly used together. By sliding the slider, the two rows of chain teeth on a pair of chain belts can be engaged or separated. At present, the sliders commonly used on the market can engage the chain teeth on a pair of chain belts during normal use. However, when the chain belts are subjected to a large pulling force in the left and right directions, the engaged chain teeth on the pair of chain belts will easily burst apart. In particular, when the chain teeth have been engaged and burst apart, the chain teeth on the chain belt are twisted, causing them to be misaligned up and down or in an oblique arch shape, causing these chain teeth to be stuck at the rear end of the slider. Therefore, it will be difficult for the slider to retreat to the point where the chain teeth burst apart for repair so that they can re-engage. In addition, when the slider retreats, the chain teeth are easily damaged, causing the zipper to be scrapped. Utility Model Content

[0018] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the drawings 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 should fall within the scope of protection of the present invention.

[0019] Reference Figure 1-Figure 5 As shown, a quick repair slider for tooth bursting comprises an upper wing plate 1, a lower wing plate 2, and a guide column 3. The upper wing plate 1 and the lower wing plate 2 are arranged relative to each other, and the guide column 3 is arranged between the upper wing plate 1 and the lower wing plate 2. A first side plate 11 and a second side plate 12 are provided on both sides of the upper wing plate 1, and the rear end portion of the first side plate 11 is provided with a first inclined surface 111, and the rear end portion of the second side plate 12 is provided with a second inclined surface 121. The rear end portion of the upper wing plate 1 is provided with an upper pressing plate 13, and the upper pressing plate 13 is provided with an upper guide surface 131. A third side plate 21 and a fourth side plate 22 are provided on both sides of the lower wing plate 2, the rear end portion of the third side plate 21 is provided with a third inclined surface 211, and the rear end portion of the fourth side plate 22 is provided with a fourth inclined surface 221. The rear end portion of the lower wing plate 2 is provided with a lower pressing plate 23, and the lower pressing plate 23 is provided with a lower guide surface 231. Specifically, after the chain teeth 51 burst, when the slider retreats, the upper guide surface 131 and the lower guide surface 231 flatten the chain teeth 51 on a pair of chain belts 5 toward the middle so that they are in the same plane. At the same time, the first inclined surface 111, the second inclined surface 121, the third inclined surface 211, the fourth inclined surface 221, the upper wing plate 1 and the lower wing plate 2 together constitute a flattening receiving cavity 4 for accommodating the chain teeth 51 in the same plane. In the process of the slider retreating, the burst chain teeth 51 are continuously flattened and enter the flattening receiving cavity 4, and the chain teeth 51 in the flattening receiving cavity 4 can re-enter the slider for engagement, and then be separated by the guide column 3, so that the slider can retreat back to the burst point of the chain teeth 51 to repair it, so that the zipper can be re-engaged. Therefore, when the slider retreats, it will not be stuck by the burst chain teeth 51, and its retreat process is smooth, avoiding damage to the chain teeth 51 and causing the zipper to be scrapped.

[0020] The upper guide surface 131 and the lower guide surface 231 are inclined surfaces or arc-shaped surfaces.

[0021] The transverse cross-section of the flattened receiving cavity 4 is an isosceles trapezoidal structure.

[0022] Reference Figure 3 、 Figure 5 As shown, the distance W1 between the front cavity opening and the rear cavity opening of the flattened receiving cavity 4 is greater than or equal to one third of the width W3 of a single link tooth 51 on the chain belt 5.

[0023] Reference Figure 3 、 Figure 5 As shown, the width W4 of the front cavity opening of the flattened receiving cavity 4 is the length W2 of the chain teeth 51 on a pair of chain belts 5 after engagement.

[0024] In one embodiment, referring to Figure 6 As shown, the rear end portions of the first side panel 11 and the second side panel 12 extend to the rear end portion of the upper pressing plate 13 and are flush with the rear end portion of the upper pressing plate 13, and the rear end portions of the third side panel 21 and the fourth side panel 22 extend to the rear end portion of the lower pressing plate 23 and are flush with the rear end portion of the lower pressing plate 23.

[0025] The present invention also provides a zipper, including a chain belt 5 and chain teeth 51 arranged on the chain belt 5, and also includes the above-mentioned burst tooth quick repair slider, which is used to allow the chain teeth 51 on a pair of chain belts 5 to engage and separate, and to repair the engaged and burst chain teeth 51.

[0026] The above are only some specific implementation methods of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
