Abstract

Disclosed is a portable heat-insulation or cold-insulation preservation box cover. A cover top (2) is sleeved on a knob (2), clamping slots (21) are formed on the cover top (2), clamping ribs (31), protruded pieces (32), slots (33) and through holes (34) are formed on a cover frame (3), the through holes (34) are communicated with a center hole formed on the cover frame (3), the cover frame (3) is sleeved on the knob (1), the clamping ribs (31) are clamped into the clamping slots (21) respectively, protrusion blocks (41) are formed on a positioning plate (4), a protruded circular wall (42) which is uneven in thickness is formed between the two protruded blocks (4), the positioning plate (4) is fixed on the knob (1), and a seal cap (5) is tensioned on the cover frame (3). The preservation box cover is convenient to open, good in sealing performance and capable of guaranteeing heat insulation or cold insulation effect of foods stored in a preservation box body.

Description

The portable type heat insulating cold insulation freezes fresh-keeping box cover

Technical field:

The utility model relates to the crisper technical field, freezes fresh-keeping box cover more specifically to the portable type heat insulating cold insulation.

Background technology:

The kind of existing crisper on market is a lot, but using the most general has two kinds, a kind of is that lid and box body adopt the flush fit mode to fasten, another kind of is to adopt lid with the vacuum type crisper of vacuum pumping hole, this the former opening ways more complicated of two kinds of crispers, and sealing property also has certain authority, although latter's sealing property is relatively good, the tooling cost of such mode is higher.

The utility model content:

The purpose of this utility model is exactly the deficiency for prior art, and provides the portable type heat insulating cold insulation to freeze fresh-keeping box cover, and it has structurally carried out ingenious improvement, and like this so that its opening and closing are more simple and convenient, its sealing property is also relatively good simultaneously.

Technology solution of the present utility model is as follows:

The portable type heat insulating cold insulation freezes fresh-keeping box cover, the caping sleeve is on knob, form bayonet socket on the caping, form on the lid frame clamping muscle, lug, opening and and be molded over the openings that the centre hole of lid frame connects, lid frame sleeve on knob and described clamping muscle be connected in the bayonet socket, form projection on the dowel disc and form the dome wall of became uneven between two projections, described dowel disc is fixed on the knob, and seal cover cap is stretched on the lid frame.

Form 4 projections on the described location, described 4 projections are evenly distributed on the circumference.

Form respectively caping reinforced rib and box frame reinforced rib on described caping and the lid frame.

Described seal cover cap is elasticity Cowhells spare.

The beneficial effects of the utility model are:

1, it only needs the just energy opening and closing of rotation knob, and is convenient and simple in the extreme.

2, its tensioning on the lid frame has seal box, and like this so that the sealing property of its integral body is fine, food insulation or the cold insulation that can guarantee to be stored in the box body freeze.

Description of drawings:

Fig. 1 is structural representation of the present utility model

Fig. 2 is the birds-eye view of lid frame

Fig. 3 is the birds-eye view of dowel disc

Among the figure: 1, knob; 2, caping; 3, lid frame; 4, dowel disc; 5, seal cover cap; 21, bayonet socket; 22, caping reinforced rib; 31, clamping muscle; 32, lug; 33, opening; 34, openings; 35, box frame reinforced rib; 41, projection; 42, dome wall.

The specific embodiment:

Embodiment: see shown in Fig. 1 to 3, the portable type heat insulating cold insulation freezes fresh-keeping box cover, caping 2 sleeves are on knob 1, form bayonet socket 21 on the caping 2, form on the lid frame 3 clamping muscle 31, lug 32, opening 33 and and be molded over the openings 34 that the centre hole of lid frame 3 connects, lid frame 3 sleeves on knob 1 and described clamping muscle 31 be connected in the bayonet socket 21, form projection 41 on the dowel disc 4 and between two projections 41, form the dome wall 42 of became uneven, described dowel disc 4 is fixed on the knob 1, and seal cover cap 5 is stretched on the lid frame 3.

Form 4 projections 41 on the described dowel disc 4, described 4 projections are evenly distributed on the circumference.

Form respectively caping reinforced rib 22 and box frame reinforced rib 35 on described caping 2 and the lid frame 3.

Described seal cover cap 5 is elasticity Cowhells spare.

Principle of work: dowel disc 4 is fixed on the knob 1, lug 32 contacts with the outside face of dome wall 42, when rotation knob 1 moves to thicker section from dome wall 42 thinner sections, the opening 33 of lid frame 3 struts so that seal cover cap 5 tensionings, whole like this lid is stretched in the box body, when rotation knob 1 moves to thinner section from dome wall 42 thicker sections, the opening 33 of lid frame 3 shrinks so that seal cover cap 5 retractions, whole like this lid is just thrown off with box body, realize the unlatching of lid, projection 41 on the dowel disc 4 knob 1 turn to the thickest with the thinnest section in contact with lug 32, play the effect of location.

Claims
