Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, to the skill in this utility model embodiment
Art scheme is clearly and completely described, it is clear that described embodiment is only this utility model
A part of embodiment rather than whole embodiments.Based on the embodiment in this utility model, ability
The every other embodiment that territory those of ordinary skill is obtained under not making creative work premise,
Broadly fall into the scope of this utility model protection.
Core of the present utility model is to provide a kind of chain stretching device for double separating zippers, and this slide fastener fills
Put and will not scratch fabric, and handsome in appearance.
Refer to the specific embodiment that Fig. 4 to Fig. 7, Fig. 4 are the provided chain stretching device of this utility model
Structural representation；Fig. 5 is the front view of the specific embodiment of the provided chain stretching device of this utility model；
Fig. 6 is the structural representation of cap in the specific embodiment of the provided chain stretching device of this utility model；Fig. 7
By the right view of cap in the specific embodiment of the provided chain stretching device of this utility model.
A kind of chain stretching device provided by the utility model, is provided with two pairs including drawing head body 3 and end
Opening the slide fastener of part 2, drawing head body 3 is provided with cap 1, the sidepiece of cap 1 is provided with for card chain link tooth
Cap lock point 11.Drawing head body 3 is positioned under slide fastener end and cap 1 buckling state, cap lock point 11
It is positioned in two double opened gaps opening part 2.
Need it is to be noted that above-mentioned drawing head body 3 is arranged on slide fastener, it is possible to slide on slide fastener
Dynamic.Cap 1 clamping the most hinged or rotating with drawing head body 3.
In prior art, cap lock point 11 is the extension that cap 1 is downward, arranges the most straight down,
Extension mainly by realizing the self-locking of slide fastener with the clamping of slide fastener coupling element.When drawing head body slides into slide fastener
During lower end position, cap lock point 11 would generally form interference, cap 1 with double parts 2 of opening of slide fastener lower end
Cannot normally fasten.
Chain stretching device provided in the present embodiment, when drawing head body 3 slides into bottom slide fastener, cap is locked
The end of point 11 is positioned in two double gaps opening part 2, cap lock point 11 with pair open part 2 and do not exist
The interference of position, cap 1 can freely fasten.The chain stretching device that above-described embodiment is provided avoids
When cap 1 cannot fasten, user or garment material are scratched, facilitate the use of slide fastener.
In the chain stretching device of above-described embodiment, part 2 can be opened by increase on the basis of existing design is double
The opened gap of end realizes, it is of course also possible to by cap lock point 11 is arranged on bending member,
In a specific embodiment provided by the utility model, cap lock point 11 is in drawing head body 3
The bending member of portion's bending, this arranges and the cap lock point 11 of bending can be made to be inserted into two double open part 2
In opened gap.Certainly, cap lock point 11 bends to the middle part of drawing head body 3, cap lock point 11
End still remains able to the effect of the chain tooth phase clamping with slide fastener.
Optionally, structure and the shape of cap lock point 11 can have multiple choices.In this utility model institute
In the specific embodiment provided, cap lock point 11 can be L-shaped bending member.L-shaped bending member
One part is connected with cap 1 body, and another part is for the chain tooth clamping self-locking with slide fastener.L-shaped is curved
The depressed part of folding piece opens part 2 towards double, double opens part 2 to dodge, it is to avoid the two forms interference.
Optionally, above-mentioned L-shaped bending member can be by being bent to form, it is also possible to by two zero
Part connection obtains, such as, be welded to connect.
In another specific embodiment provided by the utility model, cap lock point 11 bends for arc
Part, cap lock point 11 is to the medial recess of drawing head body 3.Curved bend folding piece is different from the bending of above-mentioned L-shaped
Part essentially consists in the difference of bending angle, and the kink angle of curved bend folding piece is little, it is to avoid because of bending angle
Spend the part fatiguability caused greatly.
Can be seen that by above-mentioned two embodiment the concrete shape of cap lock point 11 can have multiple, this Shen
Its planform is not defined in please.
Optionally, on the basis of any one embodiment above-mentioned, cap lock point 11 can be and cap
Cover 1 integrally manufactured integral piece, it is also possible to connected by the mode such as clamping, welding and obtain.
Fastening effect in view of cap 1 influences whether the use of slide fastener, cap 1 can be increased button
Close and control device.On the basis of any one embodiment above-mentioned, drawing head body 3 is provided with for making
The elastic component that cap 1 fastens, elastic component is connected with cap 1.In the present embodiment, by drawing head body 3
And between cap 1, elastic component is set so that cap 1 is in the state being prone to fasten, it is to avoid cap 1
Protruding scratch user.
Optionally, elastic component can be the parts that spring or shell fragment etc. have elastic telescopic ability, makees
With being to make the unmanned state being in fastening for the cap 1 in the case of force.
Optionally, on the basis of any one embodiment above-mentioned, cap lock point 11 is used for and chain
The end of tooth clamping is for having cuspidated end.Have cuspidated end and be more of value to the chain with slide fastener
Tooth carries out clamping, it is achieved stable self-locking.
Optionally, cap lock point 11 is used for the end vertical with chain tooth clamping in the upper table of drawing head body 3
Face.
Except the primary structure of above-mentioned puller device, the structure of other each several parts of this chain stretching device please be joined
Examine prior art, repeat no more herein.
In this specification, each embodiment uses the mode gone forward one by one to describe, and each embodiment stresses
Being all the difference with other embodiments, between each embodiment, identical similar portion sees mutually i.e.
Can.
Above the chain stretching device for double separating zippers provided by the utility model is carried out detailed Jie
Continue.Principle of the present utility model and embodiment are set forth by specific case used herein,
The explanation of above example is only intended to help to understand method of the present utility model and core concept thereof.Should
