Description

Waterproofing and airtight list zips head

Technical field

The present invention relates to slider of zipper fastener technical field, be specifically related to a kind of waterproofing and airtight list and zip head。

Background technology

In the manufacturing process such as diving dress, life jacket, outdoor tent, outdoor bag, often require that zipper segment has water-proof function。For solving this problem, a lot of people devise diversified waterproof slide fastener, but simply chain toothed portion and the cloth band portion of slide fastener is carried out waterproof improvement, and because of the fault of construction of slider of zipper fastener, can cause that slider of zipper fastener and packing material seam cannot tight closure, always leaving gap, water still can be permeated by this gap or enter, thus the waterproof effect of zipper segment still suffers from deficiency。

The utility model patent that the patent No. is zl200920151910.4 discloses a kind of slider head structure, it is that slide fastener is contained in slide fastener rim of the mouth with packing material interface gap place by the extension utilizing the upper and lower surface of pull head, water seals up the gap of slide fastener one end, so that cannot penetrate into。The slider of zipper fastener of this structure still suffers from the problem sliped off from interface gap, uses for a long time, and interface gap place is containing incessantly, water can enter or permeate in the same old way, even if containing, because extension and the interface gap place on upper and lower surface still suffer from gap, waterproof effect is very micro-。

Additionally, the shell fragment that the slider of zipper fastener of existing locking is dependent on slider of zipper fastener itself blocks zipper segment, the locking of this structure, not only it is easily damaged zipper segment, and of long duration, the often place of locking, it is easy to infiltration, do not have the effect of waterproof。

Summary of the invention

For the deficiency that above-mentioned prior art exists, it is an object of the invention to provide a kind of waterproof effect waterproofing and airtight list that is very good and that will not arbitrarily slip off and zip head。

For reaching above-mentioned purpose, the present invention is achieved through the following technical solutions:

Waterproofing and airtight list zips head, including pulling-on piece, upper slip lid, lower sliding cover, it is characterized in that, wherein the fixing end of pulling-on piece is two cam heads, it is connected by joint pin between upper slip lid and lower sliding cover, two cam heads of pulling-on piece are fixed on joint pin by rotating shaft, and are provided with spring between upper slip lid and lower sliding cover, are provided with waterproof gasket in lower sliding cover。

Preferably, joint pin is provided on lower sliding cover and joint pin and lower sliding cover are integrally machined and form, slip up tops has hole, and upper slip lid is connected with lower sliding cover by joint pin through slip up tops, and two cam heads of pulling-on piece are specifically fixed on the joint pin stretching out slip up tops by rotating shaft。This kind of mode is external-open, namely unzips from front, and makes full use of joint pin, in order to fixing pulling-on piece。

Preferably, joint pin is provided on slip up lid and joint pin and upper slip lid is integrally machined and forms, having hole on lower sliding cover, upper slip lid is connected with lower sliding cover by joint pin bottom lower sliding cover, and two cam heads of pulling-on piece are specifically fixed on the joint pin stretching out lower sliding cover top by rotating shaft。This kind of mode is opened in being, namely unzips from the negative, and avoids having hole, waterproof effect optimization at outside upper slip lid。

Preferably, in the inner side of upper slip lid, processing has two spring supporting posts, and the inner side correspondence at lower sliding cover processes two spring grooves that restricted spring moves, and spring one end string is on spring supporting post, and the other end is placed in spring groove。This kind of mode can make pull head two ends be more uniformly stressed。

Preferably, spring is directly installed on joint pin, and spring one end is fixed on slip up lid, and the spring other end is fixed on lower sliding cover。This design makes structure more compact, and slider of zipper fastener overall volume reduces。

Preferably, have groove at lower sliding cover edge, in groove, be placed with waterproof grommet。

Preferably, described pulling-on piece is provided with buckle, and accordingly, it is protruding that upper slip lid or lower sliding cover are provided with the clamping corresponding with buckle。

Compared to existing technologies, advantages of the present invention: present configuration compact siro spinning technology, air-tightness better effects if, it does not have leave a water gap for permeating for, waterproof effect is very good, and compress upper slip lid by pulling-on piece cam head, lock pull head, to zipper segment without damage, in addition, structural design is more reasonable, and product cost is high, is worth promoting。
