Abstract

The utility model discloses a fridge mainly comprises box and flip two, and the box passes through the hinge with one side of flip to constitute to rotate to be connected, and the opposite side is equipped with the hasp structure, and box and flip comprise top layer, nexine and the insulating layer of packing between them, its characterized in that: the sealing structure is composed of bulges arranged on the periphery of the box body, a groove on the flip cover corresponding to the inner side of the position of the bulge of the box body and a sealing ring arranged in the groove; the hinge comprises the L-shaped blade and the rotating shaft on one side, the rotating shaft is rotatably connected with the box body, the L-shaped blade is fixed on the box cover, and the bending width of the L shape is matched with the height of the sealing structure. The utility model discloses effectively improved the leakproofness of fridge, slowed down the inside and outside heat exchange speed of box effectively, extension storage's new freshness or shelf life.

Description

A kind of deep freezer

Technical field

The utility model relates to a kind of container that has thermal insulation material, is specifically related to a kind of deep freezer, is used for the low-temp storage of food, medicine etc.

Background technology

Deep freezer is used for the refrigeration of family's cosmetics, medicine, health products, can keep the freshness and the pot-life that prolongs medicine, health products of cosmetics effectively.Also there is the people deep freezer time is put fish as fishing or to be incubated when being used to carry food etc.

In the prior art, deep freezer all is by casing and renovates bipartition, and casing constitutes by hinge with a side of renovating and is rotationally connected, and opposite side is provided with hasp, and casing constitutes with renovating by top layer, nexine and the thermal insulation layer that is filled in therebetween.In general, cold storage effect is on the one hand from the heat insulation situation of thermal insulation layer, depends on the factors such as filling material, thickness of thermal insulation layer; Be by the decision of the leak tightness of casing on the other hand, and to a great extent, therefore the latter solve the sealing problem of deep freezer in occupation of leading position, is the most directly approach that improves cold storage effect.

Summary of the invention

The utility model purpose provides a kind of excellent sealing that has, and effectively improves the deep freezer of cold storage effect.

For achieving the above object, the technical solution adopted in the utility model is: a kind of deep freezer, mainly by casing and renovate bipartition, casing is rotationally connected by the hinge formation with a side of renovating, opposite side is provided with buckle structure, casing constitutes with renovating by top layer, nexine and the thermal insulation layer that is filled in therebetween, also include a hermetically-sealed construction, described hermetically-sealed construction by the projection of being located at the casing edge, renovate corresponding to the groove of casing raised position inboard and the seal ring of being located in the groove and form; The L type blade of described hinge one side and rotating shaft constitute, and described rotating shaft and casing are rotationally connected, and L type vanes fixed is on renovating, and the bending width of L type cooperates with the height of hermetically-sealed construction.

In the technique scheme, described buckle structure is, form by buckle, rotating shaft and shell fragment, described rotating shaft is fixed in and is renovated on the body, buckle through rotating shaft with renovate body and be rotationally connected, described shell fragment be positioned at buckle with renovate between, formation reseting pressuring spring structure, the end of the nearly casing of described buckle is provided with the latch part that bends inwards, and casing is provided with the draw-in groove that cooperates with latch part.When opening when renovating, upwards break buckle off with the fingers and thumb, buckle rotates around the axis, and the pressed home stage clip makes latch part break away from clamping down on of draw-in groove, opens and renovates, and unclamps buckle, and stage clip resets buckle; Close when renovating, directly press down and renovate, under the effect of reseting pressuring spring, latch part slips in the casing draw-in groove automatically.

Because the technique scheme utilization, the utility model compared with prior art has following advantage:

1. because the utility model has added hermetically-sealed construction at casing and between renovating, improve the leak tightness of box house, the inside and outside thermal exchange speed of casing that slowed down effectively, cold storage effect is greatly enhanced, and prolongs the freshness or the pot-life of storing.

The stage clip homing position type renovate buckle structure, make open and close renovate more convenient, quick.
