In the technical scheme, when the container cover is adjusted to be maximum, the adjacent fan-shaped cover plates are mutually connected, and when the container cover is gradually reduced, the adjacent fan-shaped cover plates are partially overlapped with each other.

Optionally or preferably, in the container cover with the adjustable size, the fan-shaped cover plate is arranged between the sliding rail bracket and the rotating piece, the sliding block is divided into an upper sliding block and a lower sliding block, the upper sliding block can slide in the arc-shaped sliding groove of the rotating piece, and the lower sliding block can slide in the sliding rail.

Alternatively or preferably, in the above container cover with adjustable size, the lower slider cannot rotate relative to the sliding rail. The shape of the lower sliding block can be a rectangle or other special-shaped structures, so that the fan-shaped cover plate can only slide back and forth along one direction and cannot rotate equivalently to the sliding rail bracket.

Optionally or preferably, the size-adjustable container cover further comprises a lower cover plate, and the lower cover plate covers the surface of the sliding rail support and is fixedly connected with the sliding rail support. The lower cover plate can prevent steam, oil drops and the like from being stained on the sliding rail bracket, and is more convenient to clean.

Optionally or preferably, the size-adjustable container cover further comprises an upper cover plate, and the upper cover plate is covered between the rotating member and the handle.

Compared with the prior art, the utility model discloses following beneficial effect has:

the utility model discloses a big adjustable container lid, through the dual guiding effect of rotating member and slide rail, the slider on the fan-shaped apron of cooperation can be with the rotary motion change of rotating member for the slider along the radial concertina movement of slide rail, drives fan-shaped apron and is close to or keeps away from the center pin, and then realizes the function of adjusting container lid size. The whole container cover is integrated, so that the container cover is convenient to store and take, and the size of the container cover can be adjusted by only rotating the handle during use, so that the container cover is very convenient.

Detailed Description

The technical solutions of the present invention are clearly and specifically explained and illustrated in the following figures and preferred embodiments so that those skilled in the art can better understand the present invention and implement the present invention.

Example 1

Referring to fig. 1, a container cover with adjustable size according to the present invention includes a handle 1, a rotating member 2, a sector cover plate 3 and a sliding rail bracket 4 from top to bottom.

Referring to fig. 2 and 3, the slide rail bracket 4 is composed of five slide rails 41 extending radially to the periphery along the same center, and a central shaft 42 is provided at the center.

The sector cover plate 3 is disposed between the rotating member 2 and the slide rail bracket 4, the number of the sector cover plate 3 is the same as that of the slide rail 41, and is also five, as shown in fig. 4, the sector cover plate 3 is respectively fixed with an upper slide block 31 and a lower slide block (not shown in the figure) on the upper and lower surfaces, the upper slide block 31 is cylindrical, can slide in the arc-shaped chute 21 of the rotating member 2 and can rotate relative to the arc-shaped chute 21, and the lower slide block is square, can slide in the slide rail 41 but cannot rotate relative to the slide rail.
