Abstract
The utility model relates to a closing device for a vacuum bag comprising a left and a right supporting plates, convex strips, grooves and a pressing block, wherein the left and the right supporting plates are arranged on a bag opening of a bag body; convex strips and the grooves are matched on the left and the right supporting plates; the pressing block is sheathed on peripheries of the left and the right supporting plates. The utility model has the essential technique that both edges of the left and the right supporting plates near a bag body are provided with convex stop positions matched with the side wall of the pressing block, and accordingly, the pressing block is made to move between the two stop positions. The utility model has the advantages that the pressing block is limited to slide between the stop positions on both edges of the left and the right supporting plates without falling, which is in favor of long-term use and is labor-saving, time-saving and convenient in later use; simultaneously, the utility model has the advantage of simple structure without complicated component and the manufacturing cost can not be led to increase to a great extent.
Description
[technical field]
The utility model relates to a kind of closing device of vacuum bag.
[background technology]
Vacuum bag has been widely used in the daily life, and the cotton-wadded quilt that it can will store etc. is compressed to 1/3 of original volume, is very suitable for carrying and convenient placement of people.The closing device that the vacuum bag opening part is provided with comprises raised line, groove and the pressing block that cooperatively interacts on the back plate of bag, during use, compress left and right sides back plate and drag with pressing block, raised line and groove fasten just salable, but existing pressing block all is just directly to have dragged from left and right sides back plate after the pressing, when use next time again fit get on, like this, pressing block is easy to lose, during next time use, if there is not pressing block will make raised line and groove fit good, time-consumingly require great effort again, very inconvenient.
The utility model improves at above shortcoming.
[utility model content]
Of the present utility model be to overcome the deficiency that above-mentioned pressing block is lost easily, a kind of closing device of vacuum bag simple in structure, easy to use is provided.
The utility model is to adopt following technical proposals to realize:
A kind of closing device of vacuum bag, the left and right back plate that comprises the sack place of bag, the raised line that cooperates on the left and right back plate, groove and the pressing block that is linked in left and right back plate periphery, left and right back plate is provided with the gear of projection by the edge, both sides of bag, gear cooperates with the sidewall of pressing block, thereby makes pressing block movable between two gears;
The closing device of aforesaid a kind of vacuum bag, the gear of projection can be circle, ellipse, the square of projection, also can be the raised line that adds on the left and right back plate;
The closing device of aforesaid a kind of vacuum bag adds convex tendon on the sidewall of pressing block, and convex tendon cooperates with gear.
Compared with prior art, the utlity model has following advantage: pressing block is limited between the gear on left and right back plate both sides and slides, and can not come off, and helps long-time use, and it is time saving and energy saving, convenient to use later on; Its parts simple in structure, as not have complexity can not cause manufacturing cost significantly to increase simultaneously.

[specific embodiment]
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
The opening part of vacuum bag is provided with closing device, closing device comprises left and right back plate 11,12, raised line 13, the groove 14 on the left and right back plate 11,12 at sack 2 places of bag 1 and the pressing block 3 that is linked in left and right back plate periphery, raised line 13 cooperates with groove 14, during use, compress left and right back plate 11,12 and drag with pressing block 3, raised line 13 fastens with groove 14, and is just salable.
Left and right back plate 11,12 is provided with the gear 4 of projection by the edge, both sides of bag, and gear cooperates with the sidewall 31 of pressing block 3, thereby makes pressing block activity and can not skidding off between two gears.
Certainly, we can only be provided with the gear of projection on left back plate 11 or right back plate 12, play the effect that the restriction pressing block is deviate from so equally.
The gear 4 of projection can be circle, ellipse, the square of projection, also can be the raised line that adds on the left and right back plate.
Also can add convex tendon on sidewall 31 on the pressing block 3, convex tendon cooperates with gear and can better limit pressing block and can not deviate from.
Can be provided with on the sidewall of pressing block and above-mentioned raised line 13, the cooresponding pressing groove 32 in groove 14 positions, raised line and groove are better fastened.
