Detailed description of the invention
In order to be illustrated more clearly that the technical solution of the utility model, below in conjunction with drawings and Examples, to this
The technical scheme of utility model is further elaborated, it should be apparent that, describing below is only this reality
By some novel embodiments, for those of ordinary skill in the art, do not paying creative work
Under premise, it is also possible to obtain other embodiment according to these embodiments.
As in Figure 2-4, it is the schematic diagram of this utility model reinforced chain type valve bag embodiment.This reality
Execute the reinforced chain type valve bag in example and include bag 30 and clip chain 20, and above-mentioned clip chain 20
At the top end opening of bag 30.Clip chain 20 is made up of a public chain and a fundamental chain, above-mentioned male chain and mother
Chain is separately positioned on bag 30 both sides inwall.
Include two profiles be arrangeding in parallel 21 on public chain, and the face in the outside of each profile 21 is provided with the
One hook；Fundamental chain is provided with catching groove 23, and the inwall of the both sides of this catching groove 23 is respectively provided with the second hook.Pass through
Both sides (i.e. public chain and the outside of fundamental chain) outside the opening part of pressing bag 30, can make two profiles of public chain
In 21 catching grooves 23 snapping into fundamental chain, and the first hook outside two profiles 21 on public chain hooks respectively
The second hook on one sidewall of the catching groove 23 living fundamental chain, thus realize public chain and the stable fastening of fundamental chain,
As shown in Figure 4, and realize the sealing of bag 30.
Interlocking for ease of public chain and fundamental chain and separate, the cross section of above-mentioned first hook and the second hook (is i.e. perpendicular to
The cross section in clip chain direction) convex arc-shape can be.Certainly, in actual applications, the first hook and the second hook also may be used
Use the such as shape such as arrow-shaped, barb-shaped.
For improving sealing effectiveness, two clip chains 20, and these two clip chains can be set at the opening part of bag 30
The public chain of 20 and fundamental chain can be reversed, i.e. the inwall of the side of bag 30 is respectively provided with a public chain and
Bar fundamental chain, the inwall of opposite side are correspondingly arranged a fundamental chain and a public chain.Certainly, it is possible to according to different fields
The use closed needs, and the opening at bag 30 goes out to arrange more a plurality of clip chain 20.
The centre of the catching groove 23 of above-mentioned fundamental chain can be provided with the filler rod 24 arranged along catching groove 23 length direction, and
The height of this filler rod 24 is less than the height of profile 21；When public chain and fundamental chain fasten, filler rod 24 snaps in two
Space between profile 21, and the first hook on two profiles 21 is pushed to the second hook on catching groove 23.
By which, the first hook on profile 21 can be made to be buckled in mutually with the second hook on catching groove 23
Together.Especially, the cross section (being i.e. perpendicular to the cross section of clip chain length direction) of above-mentioned filler rod 24 is three
Dihedral.
For ensureing the sealing effectiveness of bag 30 opening part, two profiles 21 can be made to fill up catching groove 23 respectively
Space between side inwall and filler rod 24.
Additionally, also can be respectively provided with abutting bar 22, and this abutting bar in the outside of two profiles 21 of public chain
The height of 22 is less than the height of profile 21；When public chain and fundamental chain fasten, two abut bar 22 and support respectively
Lean against the both sides outer wall of catching groove 23.By which, the shape of catching groove 23 can be kept, it is to avoid catching groove 23
Because being affected the sealing effectiveness of bag 30 opening part by profile 21 crimp.Especially, bar 22 is abutted
Bottom width more than top width, thus catching groove 23 can be provided strong support.
Especially, the distance between two profiles 21 on public chain can be 0.5-1.5mm, and it is applicable to bag
The thickness of body 30 occasion more than 0.025mm.
Open for ease of bag 30, the inwall of the bag 30 above the clip chain 20 of the top and/or outer
Wall is provided with one or more raised line 25, and this raised line is parallel with clip chain 20.The wherein inwall of bag 30
Raised line thus bag 30 can be avoided to be close together；The raised line of bag 30 outer wall then can increase bag at this
The frictional force of 30, is unlikely to when opening bag 30 to skid.
The above is only preferred implementation of the present utility model, it is noted that for the art
For those of ordinary skill, on the premise of without departing from this utility model principle, it is also possible to make some improvement
And retouching, these improvements and modifications also should be regarded as protection domain of the present utility model.
