Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5This utility model provides an expansion sealing mechanism for a starry sky room, including an annular base 1, a frame 2 installed on the upper end face of the annular base 1, an annular top seat 3 installed on the top of the frame 2, a transparent plate 4 installed on the side of the frame 2 and inside the annular top seat 3, an opening and closing door 5 installed on the transparent plate 4 on one side of the frame 2, an air inlet valve 6 installed on the side of one side of the frame 2, an air guide ring pipe 7 installed between two adjacent sets of frames 2, a clamping groove 8 opened on the side of the frame 2, and a sealing inner groove 9 and a sealing outer groove 10 opened on both sides of the inner wall of the clamping groove 8.

[0026] A fastening cavity 11 is provided on the inner side of the insertion groove 8. A sealing inner rubber strip 12 is movably engaged inside the sealing inner groove 9. A sealing outer rubber strip 13 is movably engaged inside the sealing outer groove 10. A sealing expansion chamber 14 is provided inside the sealing inner rubber strip 12 and the sealing outer rubber strip 13. A plugging rubber strip 15 is provided at the port of the insertion groove 8.

[0027] A fastening plate 16 is fixed to the end face of the transparent plate 4 inside the fastening cavity 11. The surface of the fastening plate 16 is provided with a serrated groove 17. Inside the fastening cavity 11, on the inner and outer sides of the fastening plate 16, an inner tensioning ring 18 and an outer tensioning ring 19 are installed. The inner tensioning ring 18 and the outer tensioning ring 19 are provided with a fastening chamber 20. An inner triangular pusher block 21 is fixed to the surface of the inner tensioning ring 18, and an outer triangular pusher block 22 is fixed to the surface of the outer tensioning ring 19. By installing and fixing the annular base 1 on the ground, the arc-shaped transparent plate 4 is inserted into the insertion groove 8 on the side of the two side frames 2. Then, the frame 2 is fixedly connected to the annular base 1. Finally, the annular top seat 3 with the annular transparent plate 4 is fixedly connected to the frame. Therefore, the starry sky room can be quickly assembled together.

[0028] Furthermore, the inner triangular pusher block 21 is adapted to the serrated groove 17 on the inner side of the fastening plate 16, and the outer triangular pusher block 22 is adapted to the serrated groove 17 on the outer side of the fastening plate 16. The inner triangular pusher block 21 contacts the serrated groove 17 on the inner side of the fastening plate 16, and the outer triangular pusher block 22 contacts the serrated groove 17 on the outer side of the fastening plate 16, so that the fastening plate 16 can be clamped and fixed from both the inner and outer sides by the inner triangular pusher block 21 and the outer triangular pusher block 22.

[0029] Furthermore, the intake valve 6 is connected to the air guide ring pipe 7, the air guide ring pipe 7 is connected to the fastening chamber 20, and the fastening chamber 20 is connected to the sealed expansion chamber 14 through the built-in hose, so that gas can be delivered into the air guide ring pipe 7 through the intake valve 6, and gas can be delivered into the fastening chamber 20 and the sealed expansion chamber 14 through the air guide ring pipe 7.

[0030] Furthermore, both the inner tensioning ring 18 and the outer tensioning ring 19 are spiral elastic rings, and one inner end of the inner tensioning ring 18 and the outer tensioning ring 19 is fixedly connected to the inner wall of the fastening cavity 11, while the outer end is free to move. The inner tensioning ring 18 and the outer tensioning ring 19 are located on the inner and outer sides of the fastening plate 16. The inner tensioning ring 18 and the outer tensioning ring 19 are spring-shaped rings that can stretch and contract but cannot expand. One inner end of the inner tensioning ring 18 and the outer tensioning ring 19 is fixedly connected to the skeleton 2, while the outer end is free to move. When gas is supplied into the fastening cavity 20, the outer end of the inner tensioning ring 18 and the outer tensioning ring 19 can extend so that the outer end of the inner tensioning ring 18 and the outer tensioning ring 19 can drive one end of the inner triangular push block 21 and the outer triangular push block 22.

[0031] Furthermore, the inner sealing strip 12 and the outer sealing strip 13 have a T-shaped cross-section. The inner sealing strip 12 and the outer sealing strip 13 are located on both sides of the transparent plate 4 and are in contact with the transparent plate 4. The sealing strip 15 is located at the connection between the inner sealing strip 12 and the transparent plate 4, and at the connection between the outer sealing strip 13 and the transparent plate 4. The T-shaped cross-section of the inner sealing strip 12 and the outer sealing strip 13 allows one side of the inner sealing strip 12 and the outer sealing strip 13 to be fixed in the inner sealing groove 9 and the outer sealing groove 10. When the inner sealing strip 12 and the outer sealing strip 13 expand, they can contact the transparent plate 4, thereby achieving a sealing effect.

[0032] Furthermore, the top of the frame 2 is fixedly connected to the annular top seat 3, and the bottom of the frame 2 is fixedly connected to the annular base 1. An arc-shaped transparent plate 4 is provided between the frames 2, and an annular transparent plate 4 is fixed inside the annular top seat 3. By installing and fixing the arc-shaped transparent plate 4 between the frames 2 and fixing the arc-shaped transparent plate 4 inside the annular base 1, the annular base 1, the frame 2 and the annular base 1 can form a starry sky room.

[0033] In use, the annular base 1 is fixed to the ground, the arc-shaped transparent plate 4 is inserted into the insertion slots 8 on the sides of the frame 2, the frame 2 is then fixedly connected to the annular base 1, and finally the annular top seat 3 with the annular transparent plate 4 is fixedly connected to the frame. This allows for quick assembly of the starry sky cabin. Simultaneously, the air inlet valve 6 is connected to an external air pump to supply gas into the cabin. The air inlet valve 6, through the air guide ring pipe 7, can supply gas to the interior of the fastening chamber 20 and the sealed expansion chamber 14. When gas enters the fastening chamber 20, it increases the internal pressure. At this time, the outer ends of the inner tension ring 18 and the outer tension ring 19 are forced outward and unfold. Therefore, the inner tension ring 18 can drive the inner triangular push block 21 to move outward, and the outer tension ring 19 can drive the outer triangular push block 22 to move inward, thus causing the inner triangular push block 21 and the outer triangular push block 22 to move inward. The outer triangular push blocks 22 tend to move closer to each other, which allows the inner triangular push blocks 21 and the outer triangular push blocks 22 to contact the serrated grooves 17 on both sides of the fastening plate 16, and to clamp and fix the fastening plate 16. Therefore, one end of the transparent plate 4 can be clamped and fixed in the fastening cavity 11. When gas enters the sealed expansion chamber 14, it can increase its internal pressure. At this time, the inner sealing strip 12 and the outer sealing strip 13 expand and contact the transparent plate 4. First, the transparent plate 4 can be clamped and fixed again. Second, the connection between the transparent plate 4 and the frame 2 can be sealed by the inner sealing strip 12 and the outer sealing strip 13. Then, the sealing strip 15 is placed at the connection between the inner sealing strip 12 and the transparent plate 4, and at the connection between the outer sealing strip 13 and the transparent plate 4, so as to achieve the effect of re-sealing. Thus, the starry sky room can be sealed and connected from the inside by expansion.
