Abstract
A zip head with a dead-lock function comprises an upper cover plate and a lower cover plate. A stop block is arranged between the front end of the upper cover plate and the lower cover plate, the two sides of the stop block respectively form a guide-in opening for chain teeth on two cloth belts of a zip to penetrate in, and a mesh opening is formed between the rear ends of the upper cover plate and the lower cover plate. The two side edges of the faces of the upper cover plate and the lower cover plate are respectively provided with a side plate, wherein the faces of the upper cover plate and the lower cover plate face to each other, each side plate comprises a guide section and a meshing section, wherein the guide section is located on the outer side of one guide-in opening and gradually inclines inwards from front to back, and the meshing section is located on the outer side of the meshing opening and extends backwards from the rear end of the guide-in section. A first arc elastic piece with the middle recessing inwards is arranged on the inner side face of the guide-in section, and a second arc elastic piece with the middle recessing inwards is arranged on the inner side face of the meshing section. The zip head with the dead-lock function can effectively prevent the zip from separating under the effect of non-pulling external force. Meanwhile, when the zip is zipped, elastic stress of the arc elastic pieces ejects and presses the chain teeth on the cloth belts, so that the chain teeth on the two cloth belts can be accurately and stably meshed.
Description
Technical field
The utility model relates to a kind of slider of zipper fastener with locking function.
Background technology
Slide fastener is normally made up of two straps, the multiple chain teeth, slider of zipper fastener and the slider of slide fastener that are arranged on two adjacent sides of strap, in conjunction with time, the length of two straps of postponing pulls slider of slide fastener, the chain tooth of slider of zipper fastener from two straps slipped over, two row chain teeth enter from two introducing ports of slider of zipper fastener front end both sides respectively, combine at the engagement mouth place of slider of zipper fastener tail end.Existing slide fastener, after combination, because slider of zipper fastener slides along strap under the effect of gravity or other external force, makes two row chain teeth separate from the end of its combination, thereby causes the slide fastener connecting sewing place of wrapping tool, clothing to separate, and affects it and normally uses.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is intended to provide a kind of slider of zipper fastener with locking function, and it can effectively prevent that slide fastener from separating under the non-effect of pulling open external force.
For achieving the above object, the utility model adopts following technical scheme:
With the slider of zipper fastener of locking function, comprise upper cover plate and lower cover, between upper cover plate and the leading section of lower cover, be provided with a block, the both sides of this block form respectively an introducing port penetrating for the chain tooth on two straps of slide fastener, form an engagement mouthful between upper cover plate and the rearward end of lower cover; The both sides of the edge of upper cover plate and lower cover opposite face are provided with side plate, and side plate comprises and is positioned at introducing port outside and intilted introduction segment and be positioned at the engagement mouthful engaged section that outside is extended back by the rearward end of introduction segment gradually from front to back; The medial surface of introduction segment is provided with first arc spring lamination of pars intermedia to convex, and the medial surface of engaged section is provided with second arc spring lamination of pars intermedia to convex.
The inner surface of the first arc spring lamination and the second arc spring lamination is provided with double wedge.
The upper surface of upper cover plate is also provided with one for mounting the slide fastener ring of pulling-on piece.
The beneficial effects of the utility model are:
Than existing slide fastener, the elastic stress that the utility model utilizes the arc spring lamination deformation of slider of zipper fastener side setting to produce, effectively prevents that slide fastener from separating under the non-effect of pulling open external force; Meanwhile, in the time of slide fastener drawing, the chain tooth on strap is inwardly pushed up pressure by the elastic stress of arc spring lamination, makes the engagement that chain tooth relative on two straps can be accurate, stable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is internal structure schematic diagram of the present utility model;
Fig. 3 is the structural representation of the another kind of slider of zipper fastener of the utility model;
Wherein: 100, slider of zipper fastener; 10, upper cover plate; 11, lower cover; 12, side plate; 121, introduction segment; 122, engaged section; 13, block; 14, slide fastener ring; 15, introducing port; 16, engagement mouthful; 17, the first arc spring lamination; 18, the second arc spring lamination.
The specific embodiment
Below, by reference to the accompanying drawings and the specific embodiment, the utility model is described further:
Referring to Fig. 1 and Fig. 2, the slider of zipper fastener 100 of the utility model band locking function, comprise upper cover plate 10 and lower cover 11, between the leading section of upper cover plate 10 and lower cover 11, be provided with a block 13, block 13 is positioned at the middle part of slider of zipper fastener 100 widths, the both sides of this block 13 form respectively an introducing port 15 penetrating for the chain tooth on two straps of slide fastener, form an engagement mouth 16 between upper cover plate 10 and the rearward end of lower cover 11.The both sides of the edge of upper cover plate 10 and lower cover 11 opposite faces are provided with side plate 12, between side plate 12 end faces of upper cover plate 10 and lower cover 11 the same sides, form a gap of passing for strap, side plate 12 is for the outside of backstop chain tooth, prevent that the two row chain teeth that fasten from separating, concrete, side plate 12 comprises and is positioned at introducing port 15 outsides and intilted introduction segment 121 and be positioned at the engaged section 122 that engagement mouthful 16 outsides are extended back by the rearward end of introduction segment 121 gradually from front to back; The medial surface of introduction segment 121 is provided with inwardly first protruding arc spring lamination 17 of the pars intermedia of slider of zipper fastener 100 widths (towards) of pars intermedia, and the medial surface of engaged section 122 is provided with inwardly second protruding arc spring lamination 18 of the pars intermedia of slider of zipper fastener 100 widths (towards) of pars intermedia.
Above-mentioned slider of zipper fastener 100 in use, two row chain teeth on two straps enter slider of zipper fastener 100 by introducing port 15 respectively, the elastic stress that the first arc spring lamination 17 produces is pressed two row chain teeth respectively towards the pars intermedia top of slider of zipper fastener 100 widths, make chain tooth relative on two straps in the combination of the end of block 13, simultaneously, the two row chain teeth that interosculate are in the time being passed by engagement mouth 16, the elastic stress that the second arc spring lamination 18 in engaged section 122 produces further inwardly pushes up and presses two row chain teeth, two row chain teeth are engaged fully, after two row chain teeth combinations, in the situation that not pulling slider of zipper fastener 100, due to the first arc spring lamination 17 and inwardly top pressure chain tooth of the second arc spring lamination 18, chain tooth makes the first arc spring lamination 17 and the second arc spring lamination 18 that deformation occur, slider of zipper fastener 100 is can not slide along strap, unless slider of zipper fastener 100 is applied to larger pulling force, under the effect of gravity and other external force, slide fastener can not be opened.
