[0035] 另外,该两缺口42、44是在注塑成型该下止10之前通过在该链带40及该链带30 上进行冲裁而成型的。 [0035] In addition, the two notches 42, 44 in the injection molding of the next stop on the prior 10 through 40 and the chain link belt with 30 punching and forming. 现有技术在注塑成型该下止时,由于与下止连接的链带具有一定弹性,不能准确定位,往往会因伸缩偏移而被该下止的成型模具的侧壁压伤。 The prior art injection molding when the next stop, since the chain belt connected at only a certain elasticity, can not accurate positioning, often sidewall mold will be offset because the next stretch of crushed dead. 而如果与该下止的插销连接处即缺口处的链带被压伤产生缺角,则使用时该链带很容易沿缺口处被撕裂。 The chain belt if the next junction plug gap at the stop that is to be crushed to produce short corner, when you use the chain belt can easily be torn along the notch. 而本发明通过在该插销14与该链带40的连接处设置该加强翼142,相当于在成型模具中对该链带40的缺口42处进行让位,合模时即使该链带40定位有偏差,该链带40的缺口42处也不会被模具侧壁压伤,从而避免了使用时该链带40沿该缺口42处被撕裂的技术问题。 The present invention, by the pin 14 and the chain 40 is provided with a connection to the reinforcement wing 142, which is equivalent to the chain in the forming mold 40 with a notch 42 were giving way, even when the clamping band 40 is positioned in the chain there are deviations, the chain belt notch 40 of 42 will not be crushed sidewall mold, thus avoiding the use of the chain belt 40 along the notch 42 technical issues are torn.

[0036] 可以理解的,该插销14及该加强翼142—体成型在该链带40上,该加强翼142对应该开槽IM设置,使得该下止10闭合时该加强翼142收容在该销孔122及开槽124内, 从外观上看不见该加强翼142。 [0036] can be understood, the pin 14 and the reinforcing wing 142- shaping the chain belt 40, which should strengthen the wing 142 pairs of slot IM settings so that only the lower 10 is closed when the reinforcement wing 142 is housed in the inner pin hole 122 and slot 124, 142 can not see the strengthening of the wing from the appearance. 在可占空间较多时,可适当增加该加强翼142的尺寸使其稍稍伸出该插座12的开槽124,以便进一步提升该下止10的平拉强度。 Can occupy space in more, it may be appropriate to increase the size of the reinforcement wing 142 to partially extend the receptacle 12 of 124 slotted in order to further enhance the level of tensile strength of the lower stop 10. 该下止10的加强翼142仅设置在该链带40的一侧,使得该加强翼142与该链带40的整体厚度较小,便于穿过该拉头20的过道25与该插座12的开槽124。 The bottom dead center reinforcement wing 142 only 10 provided in the side of the fastener tape 40 such that the reinforcing flap 142 and a smaller overall thickness of the fastener tape 40 to facilitate passage through the slider 20 of the socket 12 of the 25 slot 124. 在条件允许的情况下,也可将该加强翼142 成型于该链带40的两侧。 Under the conditions permit, it can also be the strengthening of the two flanks 142 formed in the chain belt 40. 该插销14上的斜面145使得该插销14能更容易地插入到该销孔122内,实践中也可不设置该斜面145。 Inclined surface 14 on the pin 145 so that the pin 14 can be more easily inserted into the pin holes 122, in practice the bevel 145 may not be provided. 该加强翼142的底面与该缺口42平行以避免在合链时该链带40与该止块127的抵顶使该链带40产生断裂,也可以使该加强翼142的底面稍稍凸出该链带40上的缺口42,从而尽量减少该链带40与该止块127的接触。 The strengthened underside of the wing 142 and the notch 42 parallel to avoid when you close chain of the belt 40 and the stop block 127, the excess so that the chain belt 40 have a fracture to be strengthened so that the underside of the wing 142 is slightly convex chain notched 42 40, thus minimizing the chain with contact 40 and the stopper block 127.

[0037] 请参照图6,其所示为本发明开口拉链第二实施例的示意图,该开口拉链IOOa的下止IOa与本发明第一实施例的不同之处在于:该加强翼14的底面与该插销14的底面平齐,该销孔12底部对应该插销14及其加强翼14设有一挡墙129。 [0037] Referring to FIG. 6, a schematic diagram of a second embodiment of the zipper opening its invention is shown, different from the first embodiment only in the opening zipper under IOa IOOa with the present invention is that: the reinforcement of the bottom surface of the wing 14 flush with the bottom surface 14 of the pin, the pin hole on the bottom of 12 should strengthen the wing pin (14) and is provided with a retaining wall 129 14. 通过将该加强翼142a的底面与该插销14的底面设置平齐,相比第一实施例增加了该加强翼14的长度,使得该加强翼14与该链带40a的结合更加牢固。 By strengthening the wing bottom surface 142a of the pin is flush with the bottom surface 14 is provided, as compared to the first embodiment increases the length of the reinforcing 14 wing, so that the strengthening of the wing 14 chain binding band 40a is more firmly.

[0038] 请参照图7,其所示为本发明开口拉链第三实施例的示意图,该开口拉链IOOb与本发明第一实施例的不同之处在于:该链带30及链带40对应该下止10在其上下侧面分别设有一层加强胶带31、41,该两加强胶带31、41通过热压工艺成型在该两链带30、40上。 [0038] Referring to FIG. 7, a schematic diagram of the third embodiment of the zipper opening its invention is shown, except cases of the opening of the first embodiment of the present invention is that the zipper IOOb: The chain belt 30 and the chain belt 40 pairs should 10 are provided at only one side in its upper and lower reinforce tape 31, 41, 31, 41 of the two strengthen tape hot press molding process in the two-chain belt 30,40. 该下止10的插座12及插销14及该加强翼142均设置在加强胶带31或加强胶带41上。 Socket 12 and the pin 14 and the reinforcement of the lower wing 142 only 10 are set in the tape 41 on strengthening the tape 31 or strengthened. 该加强胶带31、41的作用在于提高该两链带30、40处的强度。 The strengthening of the role of tape 31, 41 is to increase the strength of the two-chain with 30, 40 nm.
