Description

A kind of clips

Technical field

The utility model relates to a kind of packing assistant product, relates in particular to a kind of plastic bag clips.

Background technology

In daily life, seal storage after being placed on food, article in the plastic bag and become a kind of method commonly used, the form of sealing of plastics sack is diversified, wherein, adopt sealing that clips realizes sack to obtain more and more widely application with its simple and practical structure and good effect.Chinese patent CN2883208Y discloses a kind of clips, " comprise that but an end is movably hinged mutually and the holder and the clip of opening and closing; be provided with catch gear in holder, another corresponding end of clip; be characterized in that described holder, clip are made of two semicircular body; wherein: above-mentioned holder middle part has curved folder mouth; be provided with the following press strip of camber line shape at folder mouthful bottom section; be provided with the ceiling molding of joining with its arc at the following cooresponding clip end face of press strip, is provided with coarse surface on ceiling molding or the following arbitrary stitching surface of press strip." this technical scheme is by the holder of two semicircular body and the folding of clip, realization is with plastics sack leak free purpose.But this scheme phase mutual friction owing to two semicircular body foldings, cause the wearing and tearing of holder and clip wall, cause the plastic bag that is pressed from both sides to leak gas slowly, if hold in the plastic bag for liquid substance, can produce the sack drainage, and this scheme long-term use meeting makes plastic bag buckle the flange distortion, practicality is affected, and when sealed plastic bag, needs two people operation, just can finish the seal operation of plastic bag, complicated operation is loaded down with trivial details.

The utility model content

Technical problem to be solved in the utility model provides a kind of clips self wearing and tearing of avoiding, and prevents sealed plastic bag gas leakage, leaks and prevent that the sack edge-curl phenomenon from taking place, and clips simple to operate.

For solving the problems of the technologies described above, the utility model adopts following technical proposals: a kind of clips, and it is to be made of with the interpolation body that is sheathed in the tubulose outer cylinder body the rounded tubulose outer cylinder body of section; The tube wall of described tubulose outer cylinder body is provided with a groove vertically, so that the plastics sack passes thus, tubulose outer cylinder body one end tube wall is provided with a pair of through hole, and other end tube wall is sloping shape mouth, so that the plastics sack is inserted between tubulose outer cylinder body and interpolation body thus, thus sealed; Described interpolation body is a tri-prismoid, rib of this tri-prismoid is corresponding to the groove setting of tubulose outer cylinder body, tri-prismoid one end convexes with a round platform vertically, caliber coupling in described round platform diameter and the tubulose outer cylinder body, this round platform inner along be circumferentially with the same end of tubulose outer cylinder body on the projection of through hole coupling, be fixed in the tubulose outer cylinder body so that the interpolation body plugged together, described round platform outer end is provided with a flange, so that the interpolation body is fixed in tubulose outer cylinder body one end, the described tri-prismoid other end is provided with a kink, the kink that is sheathed on the interpolation body in the tubulose outer cylinder body is exposed to outside the tubulose outer cylinder body other end, so that the plastics sack is encapsulated between tubulose outer cylinder body and interpolation body along this kink cover smoothly, the arbitrary faceted pebble of described tri-prismoid is coarse surface, so that cooperate the sealed plastic sack with the interior tubular cover of tubulose outer cylinder body.

Described tubulose outer cylinder body tubular wall outside face is along being circumferentially with cyclic reinforcing rib, the place, groove both sides of described tubulose outer cylinder body and the outer surface of the corresponding opposite side tubular wall of groove are respectively equipped with the strip reinforced rib, to strengthen the intensity of tubulose outer cylinder body axial and circumferential.

Described tubulose outer cylinder body tubular wall outside face is provided with at least two pairs of open-works along diametric(al), to avoid the plastics sack to contact for a long time with the tubulose outer cylinder body and then to adhere to each other, is not easy to plastic bag is taken off from clips.

Described coarse surface is zig-zag or reticulate pattern structure.

Principle of work

At first, applying external force expands by the groove place tubulose outer cylinder body to both sides, the interpolation body is inserted in the tubulose outer cylinder body, place up with the cooresponding rib of tubulose outer cylinder body groove on the interpolation body, the through hole that is provided with on projection on the interpolation body one end round platform and the same end of tubulose outer cylinder body is corresponding, remove the external force that is applied to tubulose outer cylinder body groove place, because the stress of the circumferential reinforced rib of tubulose outer cylinder body, the groove place bounces back to original state, the plastics sack is bent into circle, is placed in outside the kink of interpolation body, slip into to the interpolation body other end by interpolation body kink one end, treat that the plastics sack places between tubulose outer cylinder body and interpolation body fully, can reach the purpose of sealed plastic sack.

The utility model is avoided clips self wearing and tearing, prevents sealed plastic bag gas leakage, leaks and prevent that the sack edge-curl phenomenon from taking place, and simple to operate.
