Further, the sealing cover can not leak air from the joint of the main body part and the cover part when in use, and the air tightness after the cover is closed is ensured. In some embodiments of the present utility model, the main body 100 is a glass plate, and the cover 200 is injection molded to the glass plate and wraps around the periphery of the glass plate. The user can observe the other side of the main body 100 through the glass plate from one side of the main body 100. In addition, the extension part 300 is rotatably disposed on the outer wall of the cover part 200 and extends along a side facing away from the center of the main body part 100, and the clip 400 is rotatably disposed on a side facing away from the center of the main body part 100 of the cover part 200. The cover part 200 is a silica gel piece, and has excellent sealing performance after being used in a covering manner. Further, the outer side wall of the covering portion 200 is provided with a vent 201, the vent 201 is disposed through and is communicated with the inner side of the covering portion 200, and the buckle 400 and the extending portion 300 are disposed corresponding to the position of the vent 201, and the buckle 400 is used for driving the extending portion 300 to rotate so as to block or open the vent 201. In some embodiments, a floating connection (not shown) is provided between the extension portion and the buckle, for example, the extension portion is located between the buckle and the vent hole, one end of the extension portion is connected with the buckle or the cover portion, and the other end extends outwards and can swing; furthermore, when the buckle rotates towards one side of the center of the vent hole, the extending part is positioned on the rotating path of the buckle, and the buckle can contact with the extending part and drive the extending part to move after rotating for a certain angle so as to press the closing part and simultaneously seal the vent hole. In some embodiments of the present utility model, the extension portion 300 is fixedly connected to the buckle 400, so that the movement path of the extension portion 300 is more accurate, the vent 201 can be better plugged, and the extension portion 300 and the buckle 400 move together to open the vent 201 when the buckle 400 rotates away from the center of the vent 201. For example, one end of the extension part 300 facing the center of the main body part 100 is connected with the cover part 200 or the buckle 400, and the other end is connected with the buckle 400, so that both ends of the extension part 300 have connection constraint, and the accuracy of the movement of the extension part 300 is ensured. In some embodiments, the extension portion and the covering portion are separately disposed (not shown in the figure), for example, two ends of the extension portion are connected with the buckle, specifically, part of the extension portion is embedded in the buckle, the installation position of the extension portion corresponds to the vent hole, and part of the extension portion is protruding and disposed in the buckle, so that the vent hole can be plugged. In some embodiments of the present utility model, referring to fig. 2, the extension 300 is integrally connected with the cover 200, reducing the risk of the extension 300 being lost during use or assembly. Further, since the vent hole 201 is also provided in the lid portion 200, the extension portion 300 integrally provided with the lid portion 200 can be accurately aligned with the position of the vent hole 201, and the vent hole 201 can be accurately blocked by the driving of the buckle 400.

It should be noted that, the sealing portion 200 made of the silica gel material can achieve excellent sealing performance after being covered, and the vent 201 is plugged or communicated when the buckle 400 rotates, so that plugging or balancing of internal and external air pressures after being covered is correspondingly achieved, and accordingly, the simplicity of sealing operation and the simplicity of uncovering operation are greatly improved, and especially, the sealing portion can be easily opened after sealing, and the use experience of a user is improved. Specifically, referring to fig. 4, when the buckle 400 is rotated downwards to be fastened with the box body, the extension part 300 is driven to move along one side facing the vent hole 201 and seal the vent hole 201, and the fresh-keeping box can seal the meal placed therein. Referring to fig. 3, the buckle 400 rotates upward to trip the case body, and simultaneously drives the extension part 300 to move along one side away from the vent hole 201 and enables the vent hole 201 to be conducted, so that the air pressure inside and outside the fresh-keeping case is balanced, and the sealing cover can be easily taken out upward.

In some embodiments of the present utility model, as shown in fig. 1 to 3, the covering portion 200 includes a base 210 and a deformation body 220, the deformation body 220 is convexly disposed along a thickness direction of the base 210, and the vent 201 is disposed at the base 210. It is easy to understand that the sealing cover 200 is deformed by pressing when the sealing cover is closed and used, so that the deformation of the vent hole 201 provided in the base 210 is reduced by absorbing and buffering the main deformation amount during the sealing deformation by providing the deformation body 220. Alternatively, the cross-section of the base 210 is square and the cross-section of the variation 220 is wedge-shaped. Further, the base 210 is not substantially deformed during use, and the probability of occurrence of self-plugging of the vent 201 is extremely low.
