Description
Technical field
The utility model relates to a kind of zipper.
Background technology
Closing of file opening of the prior art is adopted in two ways usually, and a kind of is conventional biting connecions slide fastener, and one is snap-fastener, and biting connecions slide fastener has the advantages such as sealing effect is good, but its complex structure, and cost is high, improves the cost of whole file; The advantage that snap-fastener is formed is that cost is low, but its sealing effect is poor, and the article in file easily drop out.
Utility model content
In order to solve Problems existing in background technology, the utility model provides a kind of file slide fastener, and this special slide fastener cost is low, and sealing effect is good
For achieving the above object, the utility model adopts following technical scheme:
A kind of file slide fastener, the slide fastener comprising two opposed locking edge and be slidably arranged in locking edge, it is characterized in that: locking edge is arranged on the both sides of file opening, the inner side of one of them locking edge is provided with the first arc-shaped side that twice extend along locking edge length direction, and the inner side of the first arc-shaped side sweep forms locking channel; The inner side of another locking edge arranges twice the second arc-shaped side extended along locking edge length direction, the second arc-shaped side has projection upwards;
Described slide fastener comprises top margin, the both sides of top margin are extended with side downwards, the bottom of side is inwardly extended with minor face, top margin, side and minor face define passage, two locking edge are wrapped in passage, and after slip slide fastener, the second arc-shaped side snaps in locking channel, projection on second arc-shaped side is stuck in the sweep of the first arc-shaped side, thus two locking edge are locked in together.
Described locking edge and slide fastener all adopt plastic material.
The beneficial effects of the utility model are: structure is simple, and cheap, sealing effect is good.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated
Fig. 1 is the using state schematic diagram of slide fastener described in the utility model;
Fig. 2 is the structural representation of slide fastener described in the utility model.
