Two-way separating zip

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 a double-slider zipper, especially various kinds of bags and other occasions that need to avoid unintended opening. The two sliders are divided into an open slider and a closed slider The two sliders are provided with a connection structure capable of connecting the two sliders into one body, and the slide fastener also has a release structure for releasing the connection structure. 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. In order for the zipper to have these functions, it is usually necessary to cooperate with a padlock, combination lock or other additional mechanisms. There are some defects in this way: one, under the situation that does not possess additional mechanism such as setting coded lock, ...

[0013] The double-slider zipper of the first embodiment of the present invention is shown in Figure 1, and there is a protrusion (23) on the lower bottom surface of the zipper closing slider (21), and a shrapnel is fixed on the lower bottom surface of the zipper opening slider (22). (24), the left end of the slide fastener is provided with a release structure (11) that releases the connection of the two sliders. 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). Protrusion (23) connects two sliders together, now, pull two sliders arbitrarily, two sliders move together, slide fastener is in closed state and can not be pulled open; Only when two sliders are pulled When it comes into contact with the release structure (11) at the left end of the zipper, the release...

[0015] The double-slider zipper of the second embodiment of the present invention is shown in Figure 2, and there is an arrow-shaped protrusion (23') on the bottom surface of the zipper closing slider (21'), and an arrow-shaped protrusion (23') on the lower surface of the zipper opening slider (22'). A symmetrical shrapnel (24') is fixed on the lower bottom surface, and the left end of the slide fastener is provided with a release structure (11') for releasing the connection of the two slide sliders. 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 bottom surface of the zipper connects the two sliders together. At this time, if the two sliders are pulled at will, the two sliders move together, and the zipper is in a closed state and will not be pulled open; only when The two sli...
