Description
Technical field
The utility model is related to slide fasteners, more specifically to anti-riot and waterproof the two-layer chain of large-scale tooth and small-sized tooth
Band.
Background technology
There are many functions that the slide fastener in the place such as luggage, tent needs waterproof.The way of conventional waterproof slide fastener be
Heat posted waterproof membrane on the cloth band at the chain belt back side, then pull head matched with the anti-form design worn, post the strap position of waterproof membrane
In the upper surface of chain belt, sprocket is below strap such as 106211782 spill resistant slide fastener of TaiWan, China patent.This structure is prevented
Water slide fastener is used in corner, and since the upper surface of slide fastener has strap package, sprocket below mutually squeezes so that left and right cloth originally
The state that band closes up becomes, in the bending place state that both sides are opened to left and right, the seam being open occur in left and right strap commissure
Gap is as shown in Figure 1 and Figure 2, and rainwater will be penetrated by the gap and sprocket and be gone below, so waterproof slide fastener just loses in corner
Effective water-proof function is removed.Though the gap opened is not very big, the water leaked into is also limited, cannot always claim to be real waterproof
Slide fastener, and the slide fastener for needing waterproof requirement really just cannot be satisfied, therefore the problem annoyings always waterproof slide fastener system
Quotient is made, many users and application scenario also need waterproof slide fastener truly really.And it is drawn with the waterproof on luggage
Chain has also needed to anti-riot（Anti- slide fastener punctures）Function.
Utility model content
The purpose of this utility model is to provide a kind of easily manufactured, and waterproof, anti-theft performance are good, service life is long, manufacturer
Just anti-riot and waterproof the two-layer chain band of large-scale tooth and small-sized tooth.
A kind of anti-riot and waterproof two-layer chain band of large size tooth and small-sized tooth, it includes the left and right chain rack of large size of engagement
It is stitched together respectively with the large-scale left and right matched left and right big strap of chain rack, large-scale chain belt is made；By engagement it is small-sized it is left,
Right chain rack and matched left and right small strap are stitched together respectively, and small-sized chain belt is made；Its feature is large-scale in suture
Melt coating has thermofusible elastomer material on the left and right big cloth band at the left and right chain rack back side, and the thermofusible elastomer material oozes
Enter to large-scale left and right chain rack and remove in the chain backlash of canine tooth head exceptionally, in the opposite lateral end panel of left and right big strap by heat
Molten elastomeric material is respectively formed the mutually chimeric slot in left and right, tenon waterproof sealing structure, forms waterproof large size chain belt；Waterproof is big
Upward, the small-sized left and right chain rack of small-sized chain belt is superimposed together, and make the left and right chain rack of large size of type chain belt up and down downward
Waterproof large size chain belt closes slot and the conjunction slot of small-sized chain belt or so alignment, in two outsides of large-scale left and right chain rack with list
Left and right big strap and left and right small strap are stitched together by needle or spininess respectively, or in two outsides of large-scale left and right chain rack
Position is heated to thermofusible elastomer material molten, is glued left and right big strap and left and right small strap respectively by thermofusible elastomer material
Knot is together.
The slot, tenon waterproof sealing structure refer to V-arrangement or U-shaped groove and with V-arrangement or the tenon of the recess of U-shaped
Structure.
In the small-sized chain belt except on the outer surface of small tooth head small-sized left and right chain rack exceptionally and left and right small strap
Melt coating has thermofusible elastomer material.
In the left and right big of two rows of suture pinprick positions that the left and right big strap and left and right small strap are stitched together
Heat posted is carried out with narrow waterproof joint strip above strap and covers pinprick.
The narrow waterproof joint strip is waterproof membrane or reflective membrane or pictorial trademark film.
The thermofusible elastomer material is TPU elastomeric materials.
According to anti-riot and waterproof the two-layer chain band of the large-scale tooth and small-sized tooth of said program design, when in use, waterproof
For large-scale chain belt above, small-sized chain belt is below, and matched slider head structure uses above just to wear, and here is anti-
The form worn, when use is in corner, inwardly squeezing mutually occurs the slide fastener of this structure in the left and right chain rack of large size on upper layer
The case where, the joint close position of the slot, tenon waterproof sealing structure that make left and right big strap also forms situation about inwardly mutually squeezing, outside
Chain rack generates that there are one left and right both sides to intermediate commissural compressing force to the left and right strap of the inside, and this slot, tenon
Waterproof sealing structure has elasticity, so that the joint close of left and right big cloth interband is spliced more tight, in addition more difficult leak is led to
It crosses after hot melt elastomeric material penetrates into the backlash of large-scale left and right chain rack, in the site of engagement also shape of left and right chain rack
At flexible waterproof barrier, the effect of waterproof is just more preferable, realizes the effect of real waterproof slide fastener.May be used also as needed
It being also formed with waterproof action with the small-sized chain belt below waterproof large size chain belt so that whole chain belt has dual waterproof effect,
Waterproof is tighter；And the overlap action of following small-sized chain belt and upper and lower two layers of sprocket of waterproof large size chain belt above, under making
Transverse tensile strength of the left and right chain rack of layer chainlet rack when being interlocked supports the engagement of the big chain rack on upper layer, when
External force sticker can be resisted effectively with vertical direction or when being tilted towards to pierce sudden and violent slide fastener, play the work of safeguard protection
With.
The utility model not only save by material, and processing is simple, efficient, can also respectively fixed cun be made isometric, reprocessing
At opening or silent size slide fastener.Waterproof efficacy is had more compared with general waterproof slide fastener.
