一种自锁拉头 A self-locking slider

技术领域 FIELD

本发明涉及一种拉链,特别涉及一种自锁拉头。 The present invention relates to a slide fastener, and more particularly to an auto-lock slider.

背景技术 BACKGROUND

拉链已为公知,其一般包括链牙、拉头(包括拉片)、上下止,籍由拉头在链牙上行走实现拉链的啮合与分离。 The fastener has been known, which typically include fastener elements, the slider (including the pull-tab), the upper and lower stop, membership by the slider element on the slide fastener walking achieve engagement and disengagement. 1998年4月22日公告的中国专利CN1179290A公开一种自锁式拉锁的拉头,其包括拉头本体、设于拉头本体上的板状弹簧,所述拉头本体包括下翼片、上翼片及连接所述上下翼片的导柱,拉片的一端设于板状弹簧与上翼片之间,所述拉头通过板状弹簧把拉头上翼片上的突出部分隐盖,防止其在穿着或者漂洗过程中刮伤其它织物。 April 22, 1998 announcement of China CN1179290A patent discloses a self-locking zipper pull, which includes a slider body, located in the body of the plate spring on the slider, the slider body, including the lower wing, the flap and connection flap of said upper and lower guide post, one end of the pull tab is disposed between the plate spring and the upper wing, the slider through the plate spring to pull the head of the projecting portion on the flap obscured, preventing which scratches or other fabric in wear rinsing process. 2002年12月4日公告的中国专利CN1382406A公开一种用于拉链的带有锁定装置的拉头,其是在拉片上与上翼片铰接的那一侧设置较大的开孔使其在向前方倒下时开孔内侧壁与板状弹簧之间存在间隙,防止板状弹簧在水洗过程中受到拉片的撞击而失效。 That side of the December 4, 2002 announcement of the Chinese patent discloses a CN1382406A with locking zipper pull for head unit, which is in the pull-tab and set the flaps hinged to a large hole in it When the presence of the front opening down between the inner side wall and the plate spring gap, to prevent the failure of the plate spring and the pull-tab by impact in the washing process. 2007年2月28日公告的中国专利CN1301675C则是在板状弹簧下垂体附近的拉头本体上设置一前凸体防止下垂体变形或损坏。 Chinese patent February 28, 2007 announcement of CN1301675C lordosis is a body set up under the pituitary gland to prevent deformation or damage on the slider body near the pituitary gland in the lower plate spring. 但是前述三篇专利文献所公开的技术方案都没有根本解决板状弹簧的弹簧部受撞击后失效的问题。 However, the aforementioned three technical solutions are disclosed in the patent literature no fundamental solution to the plate spring after spring part by the impact of failure.

发明内容 SUMMARY

本发明的目的是提供一种能有效避免板状弹簧的弹簧部受到撞击的自锁拉头。 Object of the present invention is to provide an effective way to avoid the plate spring portion of the spring being self-locking slider impact.

本发明所采用的技术方案是这样的:一种自锁拉头,包括下翼片、上翼片、连接上翼片与下翼片的导柱、设于上翼片上表面的板状弹簧、一端设于板状弹簧与上翼片之间的拉片,所述板状弹簧包括一体相连的定位爪、弹簧部、下垂体,所述上翼片的上表面设有凹槽,所述板状弹簧的弹簧部沉设于所述凹槽中。 Aspect of the present invention is employed is this: an auto-lock slider, includes a lower flap, the flap, the flap is connected with the lower wing guide post, provided on the upper surface of the plate spring on the flap, One end of the pull tab provided on the plate-like spring between the upper wing, the spring comprises a plate-like integrally connected claws spring portion, pituitary gland, the upper surface of the upper wing provided with a recess, the plate like a spring portion immersed in said groove.

前述自锁拉头,所述下垂体自由端附近与导柱相邻那一侧设有凸台,所述导柱设有与所述凸台适配的凹坑。 The aforementioned self-locking slider, near the free end of the pituitary gland and the adjacent side of the guide post has a boss, said guide column is provided with said projection adapted pits.

前述自锁拉头,所述上翼片上表面设有防止弹簧部过度变形的限位装置。 The aforementioned self-locking slider, the upper surface of the upper wing provided with stop means to prevent excessive deformation of the spring portion.

前述自锁拉头,所述限位装置是在上翼片中部设置一倒钩,所述弹簧部中间设有对应该倒钩的开孔。 The aforementioned self-locking slider, said retaining means is disposed in the middle of the upper wing of a barb, the intermediate portion of the spring should be provided with barbs for openings.

前述自锁拉头,所述限位装置是在弹簧部两侧的所述上翼片上设置一对对称的倒钩。 The aforementioned self-locking slider, said retaining means is a pair of symmetrical barb on the upper portion of the spring on both sides of the flap.

通过采用前述技术方案,本发明的有益效果是所述板状弹簧的弹簧部完全沉设于上翼片的凹槽中,这样弹簧部的上表面与上翼片的上表面平齐甚至更低,在水洗或者穿着过程中弹簧部不会因受外力撞击而失效,并且上翼片的上表面比较光滑,不会刮伤织物及人体皮肤;进一步的改进是在下垂体的自由端附近设置凸台与导柱的凹坑相适配防止尖锐物体从其间穿过使得板状弹簧损坏。 By using the foregoing technical solutions, the beneficial effects of the present invention is that the plate spring of the spring portion is completely immersed in the groove of the upper panel, the upper surface of the upper surface of the upper wing such flush even lower spring portion In the process of washing or wearing the spring portion is not due to external impact and failure, and the upper surface of the upper wing is relatively smooth, and will not scratch the fabric skin; further improvement is provided near the free end of the lower boss pituitary guide post and pits adapted to prevent sharp objects from damage during the spring through the plate-making.
