Abstract

The utility model provides a container sealing cover, which comprises a cover body, wherein the edge of the cover body is provided with a halberd edge which extends downwards; the halberd edge is provided with two annular flanges; a sealing rubber ring is sleeved between the two annular flanges; one side of the upper end face of the cover body is provided with a groove; a through hole is formed in the groove; the periphery of the through hole is provided with an annular flange; one side of the groove is movably connected with a small cover; the small cover is clamped in the groove through an elastic clamping block at the periphery; the middle of the bottom of the small cover is provided with a small convex post; the small convex post is connected with a silica gel cap; and the silica gel cap is just sleeved on the annular flange at the periphery of the through hole. The container sealing cover has a simple and compact structure and a reliable sealing effect, is easy to open or close, is convenient to use, and is prevented from being damaged easily, and the using cost can be effectively lowered.

Description

A kind of airtight lid for container

Technical field

The utility model relates to a kind of container cover, relates in particular to a kind of airtight lid for container.

Background technology

At present, the general sealing container for storing of Shi Yonging, itself and the multiple different type of being combined with of lid, the formula of pressing, bolt connection type are generally arranged, the halberd edge that also has the contact surface of use lid bottom and container to be provided with below O-ring seal or the lid is provided with groove or flange, is with O-ring seal in groove or flange.But the seal cover cap of this structure for guaranteeing sealing effectiveness, often designs closelyr.Often need the very big strength of expense to cover the lid of container or open, also can cause cap seal not close sometimes because of carelessness, or the situation that causes seal cover cap to damage easily, this had both wasted people's time, increased the weight of use cost again; Particularly for earthenware porcelain receptacle, because pottery will be through forming by a firing, its deformation rate is higher, its peristoma can not resemble metal or plastics make it accurate typing by mould, so the seal cover cap that present ceramic container for storing mated generally is to adopt buckle-type, promptly be provided with many card wings and block protruding at the lid outward flange, when cover cap on container body and will block the wing and detain downwards the time, the card convex clip is below the edge of container body peristoma and make lid become tight connection with container body, and the airtight container of this structure is though its sealing property better, but use inconvenient, a plurality of card wings need be detained or open to lid down or when opening, and makes troubles for people's use.

Summary of the invention

For overcoming above-mentioned existing in prior technology deficiency, the utility model provides a kind of to have reliable sealing effect and lid and opens or cover all and be easy to easy to use and durable airtight lid for container.

The utility model is to realize like this, a kind of airtight lid for container, comprise upper cover body and lower cover, be provided with the halberd edge of stretching down at the edge of upper cover body, the halberd edge lower diameter of stretching down is slightly less than upper diameter and forms stepped appearance, and the lower cover edge is provided with the halberd edge of stretching, and the halberd edge of stretching under the upper cover body is socketed in the halberd edge outside of stretching on the lower cover, the halberd edge of stretching on the lower cover is provided with annular groove, is socketed with " falling 7 " type O-ring seal on the halberd edge of stretching on annular groove reaches; In the upper surface of upper cover body one groove is set, recess sidewall is provided with guide groove, bottom portion of groove is symmetrically arranged with two through holes, be respectively arranged with pull bar in the through hole, pull bar top and switch are flexibly connecting, the pull bar bottom is provided with a projection, and the switch handle is provided with small convex pillar with the sidewall that pull bar top is connected an end, and small convex pillar and guide groove are connected and can slide around guide groove; Lower cover upper surface and pull bar correspondence position are provided with two projections, are provided with draw-in groove in the projection, and the projection that the pull bar bottom is provided with is connected in the draw-in groove.

Described pull bar top and switch plate flexibly connect by latch.

Described upper cover body and lower cover are circular, oval, square or prismatic.

Realize the utility model, because switch is connected the small convex pillar of sidewall setting and guide groove and can slide around guide groove, when being used to cover seal cover cap the time with airtight container, switch under a side pressure, because the effect of guide groove and pull bar, lower cover moves up, and the halberd edge bottom of upper cover body edge setting is stretched into O-ring seal and O-ring seal is risen greatly, makes the airtight container sealing; When wanting uncover, switch is up drawing, and lower cover moves down and makes O-ring seal break away from the halberd edge bottom of upper cover body, and O-ring seal is got back on the halberd edge of lower cover, is easy to just lid be opened; The utility model compactness simple for structure has reliable sealing effect, and lid opens or cover all and be easy to, and is easy to use, is not easy again to damage, and can effectively reduce use cost.
