Abstract
The utility model relates to a water-sealing clip chain which belongs to a bag sealing device and overcomes the defects of easy exposure and easy leakage of the existing clip chains. The utility model is provided with two strip films, wherein a fixing cramp is projected in the middle of one of the strip films, two fixing catching grooves are projected on the fixing cramp, and the fixing cramp is provided with at least two fixing catching hooks; a connection sheet is fixedly connected to the middle of the other stripe film, the other end of the connection sheet is extended with a movable cramp toward the bag opening, the movable cramp is projected with at least two movable catching hooks and two movable catching grooves, the two stripe films are respectively pasted on both sides of the bag opening, and the movable catching hooks and the fixing catching hooks are respectively pined into the corresponding fixing catching grooves and the movable catching grooves. When water or air is charged into the bag body, the movable cramp deflects so as to convert the tension of the bag opening into the pasting pressure between the movable catching hooks and the fixing catching hooks. The larger the tension of the bag opening is, the larger the pasting pressure is, and thereby improving the sealing performance for encapsulation.
Description
Affiliated technical field
The utility model relates to vacuum bag or lister bag, specifically is a kind of bag leak free clip chain that is used for.
Background technology
The clip chain that is used to seal in present known vacuum bag or the lister bag (claiming concavo-convex button again), usually constitute by two films, set firmly a groove on a film therein, set firmly one and the corresponding fin of groove on another film, two films fit in the sack both sides respectively, and fin buckles into corresponding groove can seal sack.In this structure, because of its groove and fin all are fixedly arranged on the film respectively, when in bag, adorning water or inflation, the tension force of bag opening part is delivered to groove and fin place by two films, make the bigger reversal interlocking relay of generation between groove and the fin, thereby than the fastening that is easier to separate between groove and the fin, promptly usually said easy distending.And even under the situation that it is not stressed or pressurized is less, the water in the bag also can leak out, and its leak tightness is relatively poor.
The utility model content
The purpose of this utility model provides a kind of water shutoff clip chain, to improve the above-mentioned defective of existing clip chain.
The technical scheme that the utility model adopted is: establish two strip films, film middle part is convexly equipped with a fixing cramp therein, fixedly the cramp fovea superior establish at least two fixedly catching groove, be convexly equipped with at least two fixedly button hooks, fixedly catching groove and fixedly button hook space; Another affixed a connecting piece in film middle part, the connecting strap other end extends a movable cramp to the sack inboard, movable cramp convexes with at least two movable button hooks, is arranged with at least two movable catching grooves, movable button hook and movable catching groove space, and movable button hook and movable catching groove are respectively with fixing catching groove with fixedly button hook is corresponding mutually.Two films fit in the sack both sides respectively, movable button hook and fixedly button hook buckle into respectively in corresponding fixedly catching groove and the movable catching groove.Two film upper inner are convexly equipped with a positioning rib respectively.
The beneficial effects of the utility model are: when adorning water or inflation in bag, the tension force of bag opening part directly acts on the connecting strap, when being delivered to movable cramp by connecting strap, movable cramp deflects, the tension force of sack has been transformed into movable button hook and the fixing laminate pressure between the button hook, and sack tension force more then laminate pressure is also bigger; Fasten the difficult separation in position thereby make, and seepage can not take place, improved the sealing property of sealing greatly.Yet, when outside sack, tearing the fastening position, quite easy, extremely easy to use.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further explanation:
Fig. 1 is the utility model schematic perspective view;
Fig. 2 is the utility model cross sectional representation;
Fig. 3 is the front elevation that the utility model is applied to sack;
Fig. 4 is an A-A generalized section among Fig. 3.
Number in the figure is depicted as:
1 film: 11 fixing cramps, 111 fixing button hooks, 112 fixing catching grooves; 12 connecting straps, 13 movable cramps, 131 movable button hooks, 132 movable catching grooves; 14 positioning ribs;
2 bags, 21 sacks.
The specific embodiment:
As shown in Figure 1 and Figure 2: the utility model is established two strip films 1, a film 1 middle part is convexly equipped with a fixing cramp 11 therein, fixedly be convexly equipped with at least two fixedly button hooks 111 and be arranged with at least two fixedly catching grooves 112, fixedly catching groove 112 and fixedly button hook 111 spaces on the cramp 11; Another affixed a connecting piece 12 in film 1 middle part, connecting strap 12 other ends extend a movable cramp 13 downwards, movable cramp 13 convexes with at least two movable button hooks 131 and is arranged with at least two movable catching grooves 132, movable button hook 131 and movable catching groove 132 spaces, and movable button hook 131 and movable catching groove 132 are respectively with fixing catching groove 112 with fixedly button hook 111 is corresponding mutually.Two films, 1 upper inner is convexly equipped with a positioning rib 14 respectively.
As shown in Figure 3, Figure 4: two films 1 fit in sack 21 both sides of bag 2 respectively, and movable button hook 131 fastens mutually with fixing button hook 111.When in bag 2, adorning water or inflation, the tension force of sack 21 parts directly acts on the connecting strap 12, when being delivered to movable cramp 13 by connecting strap 12, movable cramp 13 deflects to fixedly cramp 11 belows, and movable cramp 13 and fixedly cramp 11 is substantially parallel with tension direction, the tension force of sack 21 is transformed into movable button hook 131 and the fixing laminate pressure between the button hook 111, and sack 21 tension force more then laminate pressure are also bigger; Thereby it is tightr that movable button hook 131 and fixing button hook 111 are fastened, and seepage can not take place.Thereby improved the leak tightness of sealing greatly.Two positioning ribs 14 are positioned at the open end of sack 21, can prevent 1 applying of two films, so that tear sack from this.
Claims (2)
1, a kind of water shutoff clip chain is become by two strip set of films, it is characterized in that: film middle part is convexly equipped with a fixing cramp therein, fixedly the cramp fovea superior establish at least two fixedly catching groove, be convexly equipped with at least two fixedly button hooks, fixedly catching groove and fixedly button hook space; Another affixed a connecting piece in film middle part, the connecting strap other end extends a movable cramp to the sack inboard, movable cramp convexes with at least two movable button hooks, is arranged with at least two movable catching grooves, movable button hook and movable catching groove space, and movable button hook and movable catching groove respectively with fixing catching groove and fixing button hook corresponding fastening mutually.
