[0035] Example 1

[0036] Such as figure 1 As shown, the cover 200 is in the shape of a rectangular parallelepiped, and a rotating shaft 400 is transversely provided on the rear side of the cover 200. The rotating shaft 400 can rotate freely on its axis. The two ends of the rotating shaft 400 are movably connected with the inner walls on both sides. The cover plate 200 is fixedly connected to the rotating shaft 400. The rotating shaft 400 rotates freely to drive the cover plate 200 fixed with it to flip, reaching the cover plate 200. The purpose of opening or closing. The rotating shaft 400 can also be in the form of a fixed rod that does not rotate by itself. The two ends of the rotating shaft 400 are fixedly connected with the inner walls on both sides, the cover plate 200 is movably connected with the rotating shaft 400, and the cover plate 200 is turned over with the rotating shaft 400 as the axis to reach the cover plate 200. The purpose of opening or closing. In order to make the cover 200 easier to turn over, the former connection structure is preferred in this embodiment.

[0037] The drawer 100 is slidably fitted with a sliding groove (not shown) fixed on the inner rib of the refrigerator, and can be pushed and pulled back and forth.

[0038] The supporting device is used to open or close the cover 200. In this embodiment, the supporting device includes a convex structure 230 provided on the lower end surface of the cover 200 facing the drawer body 120 and a convex structure 230 provided on the drawer 100. The sliding surface 121 on which the end of the structure 230 slides.

[0039] A raised structure 230 is provided on the left and right ends of the cover 200 facing the drawer body 120, and the position is close to the front end. Flanges 123 are provided on the left and right sides of the drawer body 120. The upper surface of the flanging 123 is a sliding surface 121, A predetermined position of the sliding surface 121 is provided with an inner concave portion 122 matching the convex structure 230. The height of the convex structure 230 matches the depth of the inner concave portion 122, and the end of the convex structure 230 can be on the sliding surface 121 slide.

[0040] When the drawer 100 is pushed into the refrigerator box, the end of the protruding structure 230 slides on the sliding surface 121, and finally slides into the inner recess 122. During the sliding process, the vertical height of the front end of the cover 200 gradually decreases. And by rotating the shaft 400, the cover 200 is closed. When the drawer 100 is pulled out, the protruding structure 230 slides out from the inner recess 122. In the process of sliding out, the vertical height of the front end of the cover 200 increases, and is rotated by the shaft 400 to realize the opening of the cover 200 .

[0041] In order to enable the convex structure 230 to slide into or out of the inner concave portion 122 smoothly and smoothly, during use, the concave portion 122 is slid in and out of the convex structure 230 to save effort and not generate large impact and noise. The side slope is set gently.

[0042] Considering the height of the raised structure 230, the height of the raised structure 230 matches the depth of the inner recess 122, so that when the raised structure 230 is completely slid into the inner recess 122, the cover 200 can be flush with the drawer opening 500.

[0043] In order to increase the opening angle of the cover 200, the protruding structure 230 is arranged in an arc structure, and is bent toward the rear end of the cover 200 to form an arc structure. The protruding structure 230 is set in an arc structure to increase the opening angle of the cover 200. If the protruding structure 230 is in a linear shape, in order to ensure that the cover 200 is horizontal when the cover 200 is closed, the corresponding depth of the concave portion 122 also needs to be increased. Large, this will cause the sliding surface 121 to be too steep and difficult to push and pull the drawer 100; in order to better realize the invention and facilitate the sliding of the drawer 100, it is necessary to ensure a gentle slope, reduce the depth of the inner concave portion 122, and reduce the linear convexity. Increase the length of the structure 230. In this case, since the length of the protruding structure 230 becomes smaller, the opening angle will also become smaller, and the opening effect of the cover 200 is not good. The protruding structure 230 is arranged in an arc structure, and is bent to the rear end of the cover plate 200 to form an arc structure, which can effectively avoid the above-mentioned problems, make the slope of the sliding surface 121 gentle and the opening angle of the cover plate 200 larger.

[0044] The position of the inner recess 122 should be matched with the position of the convex structure 230 on the cover 200. Specifically, the distance between the inner concave portion 122 and the drawer door 110 is equal to the distance between the end of the convex structure 230 and the drawer door 110. The purpose of this setting is to ensure that when the convex structure 230 completely slides into the inner concave portion 122, the cover 200 After being closed, the drawer 100 can be completely pushed into the refrigerator, and the cover 200 can completely cover the drawer opening 500.

[0048] A rotating shaft 400 is transversely provided on the rear side of the cover 200. The rotating shaft 400 can rotate freely on its axis. The two ends of the rotating shaft 400 are respectively movably connected to the side plates 320 on both sides. The cover plate 200 is fixedly connected to the rotating shaft 400. The rotating shaft 400 rotates freely to drive the cover plate 200 fixed to it to turn over. The purpose of opening or closing the plate 200. The rotating shaft 400 can also be in the form of a fixed rod that does not rotate by itself. The two ends of the rotating shaft 400 are respectively fixedly connected to the side plates 320 on both sides. The cover plate 200 is movably connected to the rotating shaft 400. The cover plate 200 is turned over with the rotating shaft 400 as the axis to reach the cover. The purpose of opening or closing the plate 200. In order to make the cover 200 easier to turn over, the former connection structure is preferred in this embodiment.

[0049] The front and rear length of the plate 310 is less than the front and rear length of the drawer opening 500. The sum of the front and rear lengths of the plate 310 and the front and rear lengths of the cover 200 shall be the same as the front and rear lengths of the drawer opening 500, or slightly larger. After the cover 200 is closed, the drawer The opening 500 can be completely covered.

[0050] Due to the structure of the shelf 300 and the shelf 300 itself and the liner wall are snap-fixed, the sliding groove of the drawer body 120 does not need to be fixed on the liner wall by screws, which greatly facilitates installation. The cover plate 200 is connected to the shelf 300 through the rotating shaft 400, which avoids the problem that the rotating shaft 400 is directly fixed to the wall of the inner tank, which affects the appearance. At the same time, the cover plate 200 and the layer shelf 300 form a modular whole, which is also convenient The assembly of the cover 200 and the refrigerator.

[0051] The opening or closing manner of the cover 200 in this embodiment is the same as that of the first embodiment.

[0052] Example 3

[0053] Such as figure 2 with image 3 As shown, the cover 200 can be a whole board, but in order to reduce weight and provide users with better use effects, in this embodiment, the cover 200 is composed of an outer cover 210 and an inner cover 220. The outer cover 210 and the inner cover 220 are clamped and fixed by a hook 270, and after the two are fixed, a gap is formed in the middle. Since the middle part of the cover 200 has a hollow structure, the weight is reduced. When the drawer 100 is pushed or pulled, the friction force of the convex structure 230 due to gravity is reduced, the cover 200 can be rotated more easily, and sliding noise is effectively reduced.
