Problems solved by technology
When the push-pull plate structure is opened, either a large space is required to place the push-pull plate, or only part of the space of the mouth-shaped structure can be opened; turning the door-plate structure can realize the full opening of the mouth-shaped structure, but it is necessary to provide enough space for the door to open. Rotation, extremely limited use cases

Embodiment Construction
[0020] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.
[0021] Such as Figure 1-3 As shown, a blocking structure that can be expanded and contracted two-dimensionally includes a rotating seat 100, a fixed chute 200 and a blocking plate; the blocking plate is composed of four rotating units; the rotating unit includes two pieces of shape The same triangular plate 310, the corners at both ends of the long sides of the triangular plate 310 are provided with a hinged portion 312, and the other corner away from the long side is provided with a central pivot joint 311; set, and the central pivot joints 311 of the two triangular plates 310 are overlapped and rotationally connected; the two hinge joints 312 at the two ends of each rotational unit are hinged with the joint joints 312 at the corresponding positions of the adjacent rotational units, so that the bl...

The invention relates to the field of structures capable of being unfolded and retracted and in particular provides a blocking structure capable of being unfolded and retracted two-dimensionally. The blocking structure comprises a rotating base, a fixing slide groove and a blocking plate; the blocking plate comprises four rotating units; the blocking plate consists of the four rotating units, totaling eight triangular plates with the same shape; the two triangular plates in each rotating unit form an upper layer and a lower layer and can rotate relative to each other. When two opposite central pivoting parts of the blocking plate gradually get close, the blocking plate retracts towards the center of a mouth-shaped structure and finally forms a plate-shaped structure similar to a quadrangle and blocks the mouth-shaped structure completely; when the two opposite central pivoting parts get away gradually, the blocking plate gradually becomes annular in shape and expands towards the periphery of the mouth-shaped structure, and finally, the mouth-shaped structure is completely located in a hollow-cut position in the middle of the annular structure. Thus, the complete blocking and opening of the blocking structure are achieved.
Description
technical field [0001] The invention relates to the field of expandable and contractable structures, in particular to a two-dimensionally expandable and contractable sealing structure. Background technique [0002] In life, there are mouth-like structures in many places, such as ventilation windows, ticket windows, furnace mouths, well mouths and so on. These mouth-like structures sometimes need to be blocked, and sometimes need to be opened through, so it is necessary to arrange a freely expandable and shrinkable blocking structure at the mouth-like structure. [0003] Existing sealing structure mainly contains two kinds of forms, and a kind of is the push-pull plate-shaped structure as sliding window, and a kind of is the rotating door panel structure as rotating door. When the push-pull plate structure is opened, either a large space is required to place the push-pull plate, or only part of the space of the mouth-shaped structure can be opened; turning the door-plate str...
