Abstract

The invention discloses a claw type connecting mechanism for fins of a plastic preservation box cover. The claw type connecting mechanism comprises a box body and a box cover; the opening of the box body is provided with outward flanges; a convex ring and a groove are arranged below each flange; a seal groove is formed in the box cover and a seal ring is arranged in the seal groove; the seal ring is sealed with the opening of the box body; the edge of the box cover is provided with the fins; and the inner side of each fin is provided with a connecting mechanism. The claw type connecting mechanism is characterized in that: the connecting mechanism on the inner side of each fin comprises a clamping rib provided with a claw; the clamping rib is contacted with the convex ring of each flange of the box body; and the claw extends into the groove to hook the inner wall of the convex ring. The technical scheme has the remarkable characteristics that: the clamping rib and the claw are arranged on each fin, and are matched with the convex ring and the groove of each flange of the box body so as to achieve unexpected effect.

Description

The Alcula type bindiny mechanism of the fresh-keeping lid fin of plastics

Technical field

The present invention relates to the plastics crisper, particularly relate to the Alcula type bindiny mechanism of the fresh-keeping lid fin of plastics, belong to daily living article.

Background technology

Generally use along with houshold refrigerator, food fresh-keeping is paid attention to by people, therefore crisper is comparatively fast developed, the structure of crisper mainly comprises box body and lid, and be shaped on clamp at the box mouth outer wall of box body, be shaped on the fin of pulling at the edge of lid, fin is shaped on button or hole, by button or hole with make box body and the mutual leak-tight joint of lid after clamp cooperates.The advantage of this technology: one is to use conveniently; The 2nd, be applicable to the box of different shape (side, circle etc.), especially on the fin at lid edge, be shaped on the hole, after living clamp by borehole jack, it is firm to connect, but the shortcoming of its existence: its described clamp must be that monomer protrusion box body could cooperate with the hole, and not only consumptive material is many, and volume is increased, injection moulding adds the demoulding in man-hour difficulty, mould-manufacturing expense height.And existing button (comprising the card muscle) is owing to all be straight button the (perhaps simple card muscle), straight button (simple card muscle) and skidding off easily after the clamp of box body cooperates, and the fastening weak effect influences sealing property.

Summary of the invention

The objective of the invention is in order to overcome the shortcoming of prior art, provide bindiny mechanism and box body connection reliability on a kind of lid fin good, guarantee sealing property, and the Alcula type bindiny mechanism of the fresh-keeping lid fin of the plastics that the processing mold demoulding is easy, expense is low.

The technical scheme of the Alcula type bindiny mechanism of the fresh-keeping lid fin of plastics of the present invention is: comprise box body and lid, oral area at box body is shaped on outside flange, bulge loop and groove are arranged under the flange, in lid, be shaped on seal groove, seal ring is installed in the seal groove, seal ring seals mutually with the box body oral area, edge at lid is shaped on fin, the inboard of fin is shaped on bindiny mechanism, the bindiny mechanism that it is characterized in that described fin inboard comprises the card muscle, be shaped on claw on the card muscle, the card muscle contacts with the bulge loop of box body flange, and claw stretches on the inwall that is hooked in bulge loop in the groove.

The invention discloses the Alcula type bindiny mechanism of the fresh-keeping lid fin of a kind of plastics, its principal feature is to be shaped on the card muscle on the fin at lid edge, particularly on the card muscle, be shaped on claw, the oral area of box body is shaped on flange simultaneously, and bulge loop and groove are arranged under the flange, behind the tray cover upper box cover, flaps down is pressed, the card muscle is contacted with the bulge loop of box body, especially claw stretches on the inwall that is hooked in bulge loop in the groove, and object is hooked as the claws of a hawk in promptly a kind of bindiny mechanism with crotch, failure-free is connected to make lid and box body obtain very, has guaranteed the sealing effectiveness of crisper.And groove is that the moulding of box body self flange is easy, good looking appearance, and card muscle on the fin and claw mould-manufacturing are convenient, and the demoulding is easy, the mould reduced investment.Therefore the distinguishing feature of the technical program is to be shaped on the fin card muscle and claw, and the bulge loop and the groove fit of card muscle and claw and box body flange have obtained unexpected effectiveness.

The Alcula type bindiny mechanism of the fresh-keeping lid fin of plastics of the present invention, the head of described claw is an arc-shaped head.Fin is deviate from easily, helped opening the lid.Described box body and lid are square or oblong or circle or polygon, and the fin at lid edge is four or five or six, are shaped on one or two card muscle in every fin, are shaped on a claw at least on each bar card muscle.The Alcula type bindiny mechanism of this fin is applicable on the crisper of different shape that the fin at lid edge is determined number of elements according to the shape and the size of box body, and card muscle on every fin and claw bar number are many more, connect reliable more.

The specific embodiment

The present invention relates to the Alcula type bindiny mechanism of the fresh-keeping lid fin of a kind of plastics, as shown in Figure 1-Figure 3, comprise box body 1 and lid 2, oral area at box body 1 is shaped on outside flange 11, bulge loop 12 and groove 13 are arranged under the flange, in lid 2, be shaped on seal groove 21, seal ring 3 is installed in the seal groove, seal ring 3 seals mutually with box body 1 oral area, is shaped on fin 4 at the edge of lid 2, and the inboard of fin 4 is shaped on bindiny mechanism, the bindiny mechanism that it is characterized in that described fin 4 inboards comprises card muscle 5, be shaped on claw 6 on the card muscle, card muscle 5 contacts with the bulge loop 12 of box body flange, and claw 6 stretches on the inwall that is hooked in bulge loop 12 in the groove 13.Its principal feature is to be shaped on card muscle 5 on the fin 4 at lid 2 edges, particularly on card muscle 5, be shaped on claw 6, the oral area of box body 1 is shaped on flange 11 simultaneously, and flange has bulge loop 12 and groove 13 for 11 times, after box body 1 covers lid 2, fin 4 is pressed downwards, by there being soft connecting portion 22 curved between fin and the lid downwards, card muscle 5 is contacted with the bulge loop 12 of box body, lid is play a part to pull down, lid seal ring and box body oral area are sealed and matched, and especially claw 6 stretches on the inwall that is hooked in bulge loop 12 in the groove 13, promptly a kind of bindiny mechanism with crotch, hook object as the claws of a hawk and play drag hook, fin can not skid off voluntarily like this, and failure-free is connected to make lid 2 and box body 1 obtain very, has guaranteed the result of use of crisper.And groove 13 is that the moulding of box body self flange is easy, good looking appearance, and card muscle 5 on the fin 4 and claw 6 mould-manufacturives are convenient, and the demoulding is easy, the mould reduced investment.Therefore the distinguishing feature of the technical program is to be shaped on the fin 4 card muscle 5 and claw 6, and the card muscle cooperates with the bulge loop 12 and the groove 13 of box body flange with claw, has obtained unexpected effectiveness.The head of described claw 6 is an arc-shaped head 61.Fin 4 usefulness are pulled out easily, help opening the lid 2.Described box body 1 and lid 2 are square or oblong or circle or polygon, the fin 4 at lid 2 edges is four or five or six, in every fin, be shaped on one or two card muscle 5, on each bar card muscle, be shaped on a claw 6 at least.The Alcula type bindiny mechanism of this fin 4 is applicable on the crisper of different shape that the fin 4 at lid 2 edges is determined number of elements according to the shape and the size of box body, and 6 numbers of card muscle 5 on every fin and claw are many more, connect reliable more.
