Description
Technical field
The utility model relates to a kind of embedded slide fastener.
Background technology
Market there is inlay type slide fastener, in hook hole hook sheet on one of them sprocket being embedded on another sprocket by the extruding force of pull head to sprocket, the chain realizing slide fastener closes, for being engaged the bite of strap often through bending formation arcuate structure on current sprocket, be point cantact between pull head and sprocket, contact surface is little, once sprocket is worn with the part of pull head effect, pull head will be affected to the effect of sprocket, and then causes slide fastener not close by active chain.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of embedded slide fastener, strengthens the contact area of pull head and sprocket, and slide fastener is used more firm, slide fastener is more durable.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of embedded slide fastener, a kind of embedded slide fastener, comprise strap, sprocket and pull head, described sprocket is engaged on strap, described pull head is slidably connected between two row chain teeth, wherein a row chain tooth comprises public sprocket, another row chain tooth comprises fundamental chain tooth, described public sprocket and fundamental chain tooth correspondence are arranged, described public sprocket is provided with and hooks hole, described fundamental chain tooth is provided with hook sheet, described pull head can make hook sheet embed or depart from and hook hole when sliding, described pull head is provided with and makes hook sheet embed the stripper plate hooking hole, described sprocket is provided with and can extrudes with stripper plate the compressive plane coordinated, described compressive plane is plane.The public sprocket corresponding by the stripper plate extruding on pull head and fundamental chain tooth, in the hook hole that hook sheet on fundamental chain tooth is embedded on public sprocket, due to the setting of the compressive plane of plane on sprocket, increase the extruding contact surface of pull head and sprocket, even the active chain of public sprocket and fundamental chain tooth closes sprocket to have wearing and tearing also can ensure, slide fastener uses more firm, and slide fastener is more durable.
Improve, described strap is provided with band muscle, and described sprocket is provided with the bite be engaged with muscle, and described compressive plane is located in bite.Ensure the firm connection of sprocket and strap.
Improve, described bite is provided with pressing sheet, and described pressing sheet is pressed on strap, and described pressing sheet and stripper plate correspondence are arranged.Both further enhanced the connection of sprocket and strap, and made again pull head be connected to completely on sprocket and do not contact with chain band, the rigidity of sprocket makes pull head be easier to slide, and also avoid strap and snaps in pull head.
Improve, be formed with inner corner trim between described compressive plane and pressing sheet, described inner corner trim is right angle or acute angle.Both strengthen the connection of pull head and sprocket, in turn ensure that the squeezing action of pull head upper extrusion board to sprocket.
Improve, described bite is provided with port.Strap embeds port, strengthens bite to the connection of strap.
Improve, described pressing sheet is provided with the convex thorn that can embed strap.The connection fastness of further reinforcement sprocket and strap.
Improve, every row chain tooth comprises public sprocket and fundamental chain tooth, and described public sprocket and fundamental chain space of teeth are arranged.The chain strengthening slide fastener closes fastness, and uniform force everywhere time stressed on slide fastener is not fragile.
Improve, the connecting portion that described pull head comprises two substrates and is connected between two substrates, described stripper plate is located on substrate, and the both sides of described connecting portion are respectively equipped with the gathering sill that can pass for hook sheet.Be arranged so that hooking sheet accurately can embed and hook in hole, avoids hooking sheet skew and hinders the chain of slide fastener to close by gathering sill.
Beneficial effect:
After adopting technique scheme, a kind of embedded slide fastener of this utility model, the public sprocket corresponding by the stripper plate extruding on pull head and fundamental chain tooth, in the hook hole that hook sheet on fundamental chain tooth is embedded on public sprocket, due to the setting of the compressive plane of plane on sprocket, increase the extruding contact surface of pull head and sprocket, even sprocket there are wearing and tearing also can ensure, the active chain of public sprocket and fundamental chain tooth closes, slide fastener uses more firm, and slide fastener is more durable.
