[0013] The double slider zipper of the first embodiment of the present invention is as figure 1 As shown, there is a protrusion (23) on the bottom surface of the zipper closing slider (21), and a shrapnel (24) is fixed on the bottom surface of the zipper opening slider (22), and the top sheet (11) is fixed on the left end of the zipper tape. ). When the slide fastener is in the closed state, the closing slider (21) and the opening slider (22) are close together, and the shrapnel (24) on the bottom surface of the opening slider (22) buckles the spring clip (24) on the bottom surface of the closing slider (21). The protrusion (23) connects the two sliders together. At this time, if the two sliders are pulled at will, the two sliders move together due to the connection between the shrapnel (24) and the protrusion (23), and the slide fastener is still in a closed state. and will not be pulled apart; only when the two sliders are pulled into contact with the top sheet (11) at the ...

[0015] The double slider zipper of the second embodiment of the present invention is as figure 2 As shown, there is an arrow-shaped protrusion (23') on the lower surface of the zipper closing slider (21'), and a symmetrical shrapnel (24') is fixed on the lower surface of the zipper opening slider (22'). , the left end of the zipper tape is fixed with a top sheet (11') matched with the protrusion (23'). When the zipper is in the closed state, the closing slider (21') and the opening slider (22') are close together, and the shrapnel (24') on the bottom surface of the opening slider (22') buckles the closing slider (21'). ) The protrusion (23') on the lower bottom surface connects the two sliders together. At this time, if you pull the two sliders at will, the two sliders are connected to each other and move together. The zipper is still in the closed state and will not be pulled open. ; Only when the two sliders are pulled to contact with the top piece (11') at the left end of...

Abstract

The invention relates to a dual-drawing head zip with anti-theft function. Wherein, it is formed by zip band (10) and two drawing heads as close drawing head (21) and open drawing head (22); said two heads have the connectors (23, 24) to combine them; the zip has demount structure (11) of said connectors; when two connectors are connected without contacting demount structure, drawing heads to move them together, and the zip can not be opened; and only when drawing heads to contact the demount structure, the connection can be demounted, and drawing the open drawing head (22), the zip can be opened; when closing the zip, only needing to drawing close drawing head (21) to contact the close and open drawing heads and connect the connectors.

Description

technical field [0001] The invention relates to a double-slider zipper, which is suitable for various occasions using the double-slider zipper, especially various bags and other occasions where the zipper needs to be prevented from being accidentally opened. Background technique [0002] Generally known various slide fasteners, no matter single slider or double sliders, mostly do not possess the functions of anti-picking and preventing accidental opening.
