[0025] In order to make the technical means, creation characteristics, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific drawings.

[0026] Referring to Figures 1 to 3 , which is an example of the corner transition sealing structure provided by the utility model.

[0027] As shown in the drawing, the corner transition sealing structure of the example comprises symmetrically distributed sealing assemblies 1, and each sealing assembly comprises a plurality of rigid sealing plates 2 and a flexible transition layer 3.

[0028] The plurality of rigid sealing plates 2 are distributed side by side in the horizontal direction, and adjacent two rigid sealing plates 2 are connected by the flexible transition layer 3, the plurality of rigid sealing plates 2 are configured to be able to expand and close in the form of a sector in the vertical direction and drive the flexible transition layer 3 to expand and fold synchronously, the flexible transition layer 3 is formed with at least one folding rib 33, so that the flexible transition layer 3 can transitionally connect between the rigid sealing plates 2, ensure the stable rotation of the rigid sealing plates 2, and the flexible transition layer 3 can also synchronously realize the dustproof sealing of the corner area between the rigid sealing plates 2, and ensure the effective sealing of the sealing assembly 1.

[0029] In combination with Figures 3 to 5 , the plurality of rigid sealing plates 2 are distributed side by side in the horizontal direction, and the two ends of the rigid sealing plate 2 are respectively formed with a fixed end 21 and a moving end 22, so that the moving end 22 of the rigid sealing plate 2 can freely move in the vertical direction around the fixed end 21, therefore, the moving end 22 of the plurality of rigid sealing plates 2 moves in the vertical direction and is configured to move different strokes, so that the plurality of rigid sealing plates 2 can be expanded in the form of a sector in the vertical direction, so that the sealing assembly 1 forms a sector corner, and the sealing assembly 1 is opened.

[0030] In combination with Figure 1 and Figure 2 , in order to ensure the reliable transition connection and effective sealing between the rigid sealing plates 2, the adjacent two rigid sealing plates 2 are connected by the flexible transition layer 3, so that the adjacent rigid sealing plates 2 can be expanded and closed, and drive the flexible transition layer 3 to expand and fold synchronously, so that the flexible transition layer 3 can improve the cooperation stability of the rigid sealing plates 2 and ensure the dustproof sealing between the adjacent rigid sealing plates 2.

[0031] In combination with Figure 6, specifically, the flexible transition layer 3 is configured as a fan ring and is distributed between two adjacent rigid sealing plates 2, two sides of the flexible transition layer 3 are connected to opposite sides of the two adjacent rigid sealing plates 2 respectively, and the outer edge 32 of the flexible transition layer 3 corresponds to the moving end 22 of the rigid sealing plate 2, and the inner edge 31 corresponds to the fixed end 21, so that the flexible transition layer 3 can realize the transition connection of the two adjacent rigid sealing plates 2, and when the moving ends 22 of the two adjacent rigid sealing plates 2 are unfolded away from each other around the fixed end 21 in the vertical direction, the flexible transition layer 3 can be unfolded synchronously, at this time, the flexible transition layer 3 can seal the corner area unfolded by the two adjacent rigid sealing plates 2, and ensure that the two adjacent rigid sealing plates 2 form a fan-shaped unfolding, thereby improving the stability of the sealing assembly 1.

[0032] Further, since the flexible transition layer 3 has a certain flexibility, when the two adjacent rigid sealing plates 2 produce a deflection angle in the vertical direction during the movement of moving away from each other, the flexible transition layer 3 can also stably and synchronously offset and unfold with the two adjacent rigid sealing plates 2, and ensure the stable transition connection and effective sealing of the two adjacent rigid sealing plates 2, further ensuring the stability and reliability of the sealing assembly 1.

[0033] Correspondingly, when the moving ends 22 of the two adjacent rigid sealing plates 2 are closed to each other around the fixed end 21 in the vertical direction, the flexible transition layer 3 can be folded and closed synchronously, so that the two adjacent rigid sealing plates 2 return to the initial horizontal distribution state.

[0034] In combination Figure 6 In order to stably fold and close the sealing structure, at least one folding ridge 33 is formed on the flexible transition layer 3, so that when the two adjacent rigid sealing plates 2 are closed to each other, the folding ridge 33 can guide the folding direction of the flexible transition layer 3, and the flexible transition layer 3 is folded along the folding ridge 33, so that the flexible transition layer 3 does not produce offset during folding, and the rigid sealing plate 2 can always return to the initial horizontal distribution state, thereby improving the stability and reliability of the sealing structure.

[0035] Specifically, the folding ridge 33 extends from the outer edge 32 to the inner edge 31 along the flexible transition layer 3 and is distributed along the radius of the flexible transition layer 3, so as to ensure that the folding ridge 33 can guide the regular folding of the flexible transition layer 3, thereby driving the stable closing of the rigid sealing plate 2 to the horizontal state.

[0036] Furthermore, the folding ribs 33 are distributed in the outer edge 32 region of the flexible transition layer 3, forming a gap with the inner edge 31 of the flexible transition layer 3. As an example, in this example, the folding ribs 33 extend from the outer edge 32 to the inner edge 31, covering 4 / 5 of the radius of the flexible transition layer 3, and the gap with the inner edge 31 is 1 / 5 of the radius of the flexible transition layer 3. This allows the folding ribs 33 to increase the stability of the flexible transition layer 3. When the flexible transition layer 3 is unfolded, the folding ribs 33 can support each other. At the same time, when the flexible transition layer 3 is folded, the folding ribs 33 can guide the folding direction without extending to the inner edge 31, causing the flexible transition layer 3 to deform, thereby improving the reliability and service life of the flexible transition layer 3.

[0037] In some embodiments, multiple uniformly distributed folding ribs 33 can be formed on the flexible transition layer 3, so that the flexible transition layer 3 can be folded gradually along the multiple folding ribs 33 during the folding process, ensuring the folding stability of the flexible transition layer 3. At the same time, during the unfolding process of the flexible transition layer 3, the multiple folding ribs 33 can act synchronously to support the flexible transition layer 3.

[0038] Here, the area of ​​the flexible transition layer 3 can be adaptively adjusted according to the unfolding spacing of the adjacent rigid sealing plates 2. Correspondingly, the number of folded ribs 33 distributed on the flexible transition layer 3 can be adaptively adjusted according to the area of ​​the flexible transition layer 3. When the area of ​​the flexible transition layer 3 is large, the number of folded ribs 33 can be appropriately increased to ensure the reliability of the flexible transition layer 3.

[0039] Furthermore, the flexible transition layer 3 is preferably made of canvas, which makes the flexible transition layer 3 more durable, breathable and waterproof, and can meet the needs of outdoor use. This effectively seals the corner of the sealing component 1 and is easy to wash and replace.

[0040] The flexible transition layer 3 and the rigid sealing plate 2 thus cooperate to enable several rigid sealing plates 2 to cooperate with each other to stably unfold and close, and drive the flexible transition layer 3 to unfold and fold synchronously along the folding rib 33, so that the symmetrically distributed sealing components 1 can be stably unfolded to open the sealing components for unloading, and ensure effective dustproof sealing in the corner area of ​​the unfolded sealing components 1, thereby making the sealing structure stable and reliable.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
