Description
Technical field
The utility model is related to slide fasteners, specifically provide a kind of Antitheft zipper for being difficult with sharppointed article and disassembling.
Background technology
Prior art slide fastener includes two zipper strips and pull head, and the chain tooth intermeshing of two zipper strips, which reaches, is closed case bag
The effect of mouth.Pull head is used to being closed or opening slide fastener.But the chain tooth of the prior art slide fastener engagement and it is insecure, use ball pen
Stroke of exerting oneself in sharppointed articles insertion gap is waited slide fastener can be opened.With the promotion of luggage cloth anti-cutting performance, existing skill
Art slide fastener becomes link most weak in luggage anti-theft performance.
The content of the invention
The purpose of this utility model is to provide a kind of Antitheft zipper for being difficult with sharppointed article and disassembling.
In order to realize foregoing invention purpose, the utility model Antitheft zipper includes two zipper strips and pull head, pull head are sleeved on
On two zipper strips, two zipper strips are equipped with the chain tooth of equidistant arrangement.The connecting portion one side of chain tooth and slide fastener band connection, connection
Portion's opposite side extends a T-shaped buckle.The vertical projection of T-shaped buckle is T-shaped, the lower end of " T " font and the company of chain tooth
Socket part connects.Two vertical snapping grooves are formed in the both sides of T-shaped buckle.In the middle part of snapping groove, from the connecting portion of chain tooth
Extend a positive stop lug boss.The top middle portion of T-shaped buckle sets that there are one horizontal limiting grooves.The width of limiting groove, depth
Size is equal or slightly larger than the width of positive stop lug boss, depth dimensions, and is in together on a horizontal plane.When slide fastener is closed, first
The positive stop lug boss of the chain tooth of zipper strip is embedded in the limiting groove of the chain tooth of the second zipper strip, the limit convex of the chain tooth of the second zipper strip
Platform is embedded in the limiting groove of the chain tooth of the first zipper strip.
Preferably, the top and bottom of chain tooth are arc-shaped, the floor projection entirety semicircular in shape of chain tooth.Correspondingly, pull head
Endoporus is integrally rounded.
Preferably, zipper strip is plastic-steel part.Chain tooth is connected with zipper strip welding.
The utility model Antitheft zipper is by the improvement of chain teeth structure, and T-shaped buckle is so that can after two zipper strip engagements
Larger horizontal pull is born without threading off；Positive stop lug boss and limiting groove limit the position on vertical direction between chain tooth,
So that the dropout that will not be misplaced between chain tooth by the pressure of vertical direction.Zipper strip is steel-plastic piece, possesses certain rigidity so that
Chain tooth is more difficult to occur to swing when mutually squeezing closure to thread off.After tested, the horizontal drawing that the utility model Antitheft zipper can be born
Power possesses outstanding anti-theft performance more than 200 jin.The top and bottom of the chain tooth of the utility model Antitheft zipper are arc-shaped so that
Sharppointed article is difficult to the gap being inserted between chain tooth, further enhances anti-theft performance.The top and bottom of chain tooth are arc-shaped, pull head
Another advantageous effect of the whole rounded structure of endoporus be：When drawing pull head closed zipper, chain tooth obtains the radial direction of bigger
Pressure so that closed zipper is more laborsaving.
Description of the drawings
Fig. 1, Fig. 2 are the structure diagram of Antitheft zipper；
Fig. 3, Fig. 4 are the structure diagram of zipper strip.
Specific embodiment
The preferred embodiment in the utility model is further described below in conjunction with the accompanying drawings：
As shown in Figure 1, 2, the utility model Antitheft zipper includes two zipper strips 01,02 and pull head 03, pull head 03 are sleeved on
On two zipper strips 01,02, two zipper strips are equipped with the chain tooth 11,21 of equidistant arrangement.The top and bottom of chain tooth 11,21 are in circular arc
Shape, the floor projection entirety semicircular in shape of chain tooth.Correspondingly, the endoporus of pull head 03 is integrally rounded.The endoporus of pull head 03 is equipped with
One vertical baffle 31, for squeezing and opening two zipper strips.
As shown in Figure 3,4, the connecting portion 12 of chain tooth, 22 one sides are connected with zipper strip 01,02, connecting portion opposite side extension one
A T-shaped buckle 13,23.The vertical projection of T-shaped buckle is T-shaped, and the lower end of " T " font and the connecting portion of chain tooth connect.
Two vertical snapping grooves are formed in the both sides of T-shaped buckle 13,23.In the middle part of snapping groove, extend from the connecting portion of chain tooth
One positive stop lug boss 14,24.The top middle portion of T-shaped buckle sets that there are one horizontal limiting grooves 15,25.Limiting groove 15,25
Width, depth dimensions be slightly larger than width, the depth dimensions of positive stop lug boss 14,24, and be in together on a horizontal plane.Slide fastener closes
During conjunction, the positive stop lug boss 14 of the chain tooth of the first zipper strip is embedded in the limiting groove 25 of the chain tooth of the second zipper strip, the second zipper strip
Chain tooth positive stop lug boss 24 be embedded in the first zipper strip chain tooth limiting groove 15.
Zipper strip 01,02 is plastic-steel part.Chain tooth 11,21 is connected with zipper strip 01,02 welding.
