Abstract

The utility model provides an improved preserving box lid, which is characterized in that a knob (1) is inserted into a lid top (2); bayonets (21) are formed in the lid top (2); clamping ribs (31), lugs (32), openings (33), and through holes (34) which are communicated with a center hole formed in a box lid frame (3) are formed on the box lid frame (3); the knob (1) is inserted into the box lid frame (3) and the clamping ribs (31) are clamped in the bayonets (21); lugs (41) are formed on a positioning plate (4) and a convex round wall (42) with uneven thickness is formed between each two lugs (41); and the positioning plate (4) is fixedly arranged on the knob (1), and a sealing cover (5) is tensioned on the box lid frame (3), so the improved preserving box lid is easier to open and the sealing performance is good.

Description

A kind of improved fresh-keeping lid

Technical field:

The utility model relates to the crisper technical field, more specifically to a kind of improved fresh-keeping lid.

Background technology:

The kind of existing crisper on market is a lot; But using the most general has two kinds, and a kind of is that lid and box body adopt the flush fit mode to fasten, and another kind of is to adopt lid to have the vacuum type crisper of vacuum pumping hole; This former opening ways more complicated of two kinds of crispers; And sealing property also has certain defective, though latter's sealing property is relatively good, the tooling cost of such mode is than higher, complex structure.

The utility model content:

The purpose of the utility model is exactly the deficiency to prior art, and a kind of improved fresh-keeping lid is provided, and it has structurally carried out ingenious improvement, makes that like this its opening and closing are more simple and convenient, and its sealing property is also relatively good simultaneously.

The technological solution of the utility model is following:

A kind of improved fresh-keeping lid; The knob sleeve forms bayonet socket on the caping on 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; The knob sleeve on the lid frame and said clamping muscle be connected in the bayonet socket; Form projection on the dowel disc and between two projections, form the dome wall of became uneven, said dowel disc is fixed on the knob, and seal cover cap is stretched on the lid frame.

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

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

Said seal cover cap is an elasticity Cowhells spare.

Form the shaped as frame groove on the said seal cover cap, the lid frame is stretched in the shaped as frame groove.

The beneficial effect of the utility model is:

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

2, its tensioning on the lid frame has seal box, makes that like this its single-piece sealing property is fine.

Description of drawings:

Fig. 1 is the utility model perspective exploded view;

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

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

Fig. 4 is the cutaway view of seal cover cap.

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; 51, shaped as frame groove.

The specific embodiment:

Embodiment: see shown in Fig. 1 to 4; A kind of improved fresh-keeping lid; Knob 1 sleeve forms bayonet socket 21 on the caping 2 on 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; Knob 1 sleeve on lid frame 3 and said 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, said 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 said dowel disc 4, said 4 projections are evenly distributed on the circumference.

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

Said seal cover cap 5 is an elasticity Cowhells spare.

Form shaped as frame groove 51 on the said seal cover cap 5, lid frame 3 is stretched in the shaped as frame groove 51.

Principle of work: dowel disc 4 is to be fixed on the knob 1 through bonding mode, and lug 32 contacts with the outside face of dome wall 42, when rotary knob 1 moves to thicker from dome wall 42 thin portions; The opening 33 of lid frame 3 struts and makes seal cover cap 5 tensionings; Whole like this lid is stretched in the box body, when rotary knob 1 when 42 thicker on dome wall moves to thin portion, the opening 33 of lid frame 3 shrinks and makes seal cover cap 5 retractions; Whole like this lid is just thrown off with box body; Realize the unlatching of lid, the projection 41 on the dowel disc 4 knob 1 turn to the thickest with the thinnest portion in contact with lug 32, play the effect of location.
