The utility model discloses a constituting one between hook and the roof of upper saddle and sealing the through -hole, no matter the dynamics how, does not worry all that the stay cord breaks away from the hook piece to the comprehensive pulling force of reinforcing begin chain, even and behind the repetitious usage, the hook piece is non -deformable also, prolong the life of begin chain.
Description
Technical field
The utility model relates to a kind of sealing begin chain.
Background technology
As shown in Figure 1, begin chain is used for slide fastener of unblanking in sliding manner, it generally comprises upper saddle 16 lower slider relative with upper saddle 16 12, be connected to joint pin (not shown) between upper saddle 16 and lower slider 12, is installed on the hook on upper saddle 16.Existing hook one end connects upper saddle 16, certain breach is provided with between the other end and upper saddle 16, load hook in by pulling-on piece along interval for workman, this kind of structure assembling comparatively bothers, and when using, pulling-on piece is pullled downwards along breach, if firmly excessive, easily pulling-on piece is pullled out outside hook, and after repeatedly using, hook easily fractures due to distortion, affects the begin chain life-span
In addition, angle between the two side of the upper saddle 16 of existing begin chain and roof is 90 degree, when the begin chain of this kind of structure is installed on slide fastener, two right angles of the rear end of upper saddle 16 and chain tooth are separated by larger distance, thus make begin chain not firmly to be installed on slide fastener, repeatedly use, be easy to quick-fried chain, namely begin chain is easy to depart from slide fastener.
Moreover the joint pin of existing begin chain is generally cuboid, affect the smooth feeling of slide fastener, and can owing to rubbing slide fastener and shorten the slide fastener life-span for a long time.
Utility model content
For the deficiencies in the prior art, the utility model is intended to provide a kind of sealing begin chain solved the problems of the technologies described above.
For achieving the above object, the utility model adopts following technical scheme:
A kind of sealing begin chain, it comprises upper saddle, lower slider, hook and joint pin; The front end of this upper saddle connects the front end of lower slider by joint pin, and this upper saddle is opposing parallel with this lower slider, and the two ends of this hook are all installed on the roof of this upper saddle, forms one and seal through hole between hook and the roof of upper saddle.
Preferably, a spacing press strip is respectively established between the two side of this upper saddle and roof, the side of each spacing press strip is surrounded by plane and arc-shaped concave, the lower end of this arc-shaped concave connects the sidewall of this upper saddle, the upper end of arc-shaped concave connects the lower end of this plane, and the upper end of this plane connects the roof of this upper saddle.
Preferably, this joint pin is surrounded by the rear wall of an antetheca, an arc surface and the sidewall of two planes.
Preferably, the lower surface of the roof of this upper saddle is provided with a upper limit bar, and one end of this upper limit bar connects this joint pin, and the other end extends to the rear end of this upper saddle, and this upper limit bar is positioned at the middle part of the roof of this upper saddle.
Preferably, the upper surface of the diapire of this lower slider is provided with positive stop strip, and one end of this lower limit bar connects this joint pin, and the other end extends to the rear end of this upper saddle, and this lower limit bar is positioned at the middle part of the roof of this lower slider.
Preferably, this upper limit bar, be respectively provided with the positive stop of a triangle between this lower limit bar and this joint pin.
The beneficial effects of the utility model are at least as follows:
Form one between hook of the present utility model and the roof of upper saddle and seal through hole, regardless of dynamics, all do not worry that stay cord departs from hook, thus strengthen the comprehensive pulling force of begin chain, even and if after repeatedly using, hook is not yielding yet, extend the service life of begin chain.

Fig. 1 is the structure chart of prior art begin chain.
Fig. 2 is the side view structural representation of the better embodiment of the utility model sealing begin chain.
Fig. 3 is the rearview structural representation of the begin chain of Fig. 2.
Fig. 4 is the top view structural representation of the begin chain of Fig. 2.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described further:
Refer to Fig. 2 to Fig. 4, the utility model relates to a kind of sealing begin chain, and its better embodiment comprises its better embodiment and comprises upper saddle 24, lower slider 21, hook 26 and joint pin 23;
The front end of this upper saddle 24 connects the front end of lower slider 21 by joint pin 23, this upper saddle 24 is opposing parallel with this lower slider 21, the two ends of this hook 26 are all installed on the roof of this upper saddle 24, form one and seal through hole 265 between the roof of hook 26 and upper saddle 24.So, forming traction structure by stay cord through sealing through hole, regardless of dynamics, all not worrying that stay cord departs from hook 26, thus strengthening the comprehensive pulling force of begin chain, even and if after repeatedly using, hook 26 is not yielding, the service life of prolongation begin chain yet.
In the present embodiment, a spacing press strip 241 is respectively established between the two side of this upper saddle 24 and roof, the side of each spacing press strip 241 is surrounded by plane and arc-shaped concave, the lower end of this arc-shaped concave connects the sidewall of this upper saddle 24, the upper end of arc-shaped concave connects the lower end of this plane, and the upper end of this plane connects the roof of this upper saddle.When this pull head is applied to slide fastener, on this upper saddle 24 two spacing press strips 241 mate contact chain tooth, effectively can avoid the sudden and violent chain of slide fastener.
Preferably, this joint pin 23 is surrounded by the rear wall of an antetheca, an arc surface and the sidewall of two planes, so, when this pull head is applied to slide fastener, the rear wall of this arc surface contacts with the chain tooth of slide fastener is round and smooth, can reduce the friction of joint pin 23 pairs of chain teeth, reduce chain odontotripsis, extend the service life of slide fastener.
Preferably, the lower surface of the roof of this upper saddle 24 is provided with a upper limit bar 25, and one end of this upper limit bar 25 connects this joint pin 23, and the other end extends to the rear end of this upper saddle 24, and this upper limit bar is positioned at the middle part of the roof of this upper saddle.
