[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Depend on Figures 1-7 The present invention includes a ground 1 and a support mechanism. An arch 2 is fixedly installed on the upper end of the ground 1, and a plurality of support plates 6 are slidably connected on the arch 2 and abut against the arch 2. The support mechanism includes an installation component 3 fixedly installed on the upper end of the ground 1. The installation component 3 includes a horizontal plate and two vertical plates. The bottom of the two vertical plates is fixedly connected to the upper end of the ground 1. The horizontal plate is fixedly installed on the upper end of the two vertical plates. A support block 4 is fixedly installed on the upper end of the horizontal plate.

[0025] A support block 4 is fixedly installed on the upper end of the mounting component 3. A first drive rod 5 is fixedly connected to the upper end of the support block 4. A connector is fixedly connected to the output end of the first drive rod 5. The connector is fixedly connected to the support plate 6. The connector includes a mounting cylinder 13 fixedly installed on the output end of the first drive rod 5. A connecting column 12 that slides against the inner wall of the mounting cylinder 13 is slidably connected to the mounting cylinder 13. The connecting column 12 is fixedly connected to the support plate 6. A first sliding groove 14 is provided on the connecting column 12. A limiting rod 10 is slidably connected in the first sliding groove 14. The limiting rod 10 passes through the mounting cylinder 13 and is slidably connected to it. A first spring 11 is fixedly installed on the limiting rod 10 and the mounting cylinder 13.

[0026] When the first drive rod 5 is opened, its output end drives the mounting cylinder 13 to move upward. The mounting cylinder 13 then drives the connecting column 12 to move upward, which in turn drives the support plate 6 to move upward. The support plate 6, moving upward, comes into contact with the arch 2 and exerts a thrust on the arch 2, thus providing support. When a different size support plate 6 needs to be replaced, pulling the limiting rod 10 pulls it out of the first sliding groove 14, freeing the connecting column 12 from its limitation. The support plate 6 is no longer restricted and can be disassembled. During installation, the connecting post 12 is inserted into the mounting cylinder 13. When the connecting post 12 abuts against the bottom of the mounting cylinder 13, the limiting rod 10 is exactly opposite to the first sliding groove 14. When the limiting rod 10 is released, the limiting rod 10 will move into the first sliding groove 14. The first spring 11 can ensure the stability of the limiting rod 10 in the first sliding groove 14, thereby ensuring that the connecting post 12 is restricted, thus completing the restriction of the support plate 6 and completing the installation of the support plate 6.

[0027] Supporting components are fixedly installed on both sides of the support block 4. The supporting components include two connecting plates 8 fixedly installed on the support block 4. A connecting rod 9 is fixedly installed on the connecting plate 8. Two fixing plates 15 are fixedly installed on the two supporting plates 6. A fixing rod 16 is fixedly installed on the fixing plate 15. A connecting block 17 is rotatably connected to the connecting rod 9 and the fixing rod 16. A second driving rod 7 is fixedly connected to one end of the connecting block 17. A disassembly component is connected to the output end of the second driving rod 7. The disassembly component is fixedly connected to the connecting block 17 on the fixing rod 16.

[0028] Multiple support components can support the arch 2 in different directions. When the second drive rod 7 is opened, the output end of the second drive rod 7 will drive the connecting cylinder 21 to move. The connecting cylinder 21 will drive the mounting column 18 to move. The mounting column 18 will drive the connecting block 17 connected to the fixed rod 16 to move. The connecting block 17 will drive the fixed rod 16 to move. The fixed rod 16 will drive the fixed plate 15 to move. The fixed plate 15 will drive the support plate 6 to move. The support plate 6 will move and abut against the arch 2, thereby generating pressure to support the arch 2.

[0029] When the support position needs to be changed, the support plate 6 is moved. The support plate 6 will drive the fixed plate 15 to rotate, the fixed plate 15 will drive the connecting block 17 to rotate, the connecting block 17 will drive the connecting cylinder 21 to rotate, the connecting cylinder 21 will drive the second drive rod 7 to rotate, the second drive rod 7 will drive the connecting block 17 connected to the connecting rod 9 to rotate, and the connecting block 17 will rotate around the connecting rod 9. The second drive rod 7 is opened, and the output end of the second drive rod 7 will drive the connecting cylinder 21 to move. The connecting cylinder 21 will drive the mounting column 18 to move, the mounting column 18 will drive the connecting block 17 connected to the fixed rod 16 to move, the connecting block 17 will drive the fixed rod 16 to move, the fixed rod 16 will drive the fixed plate 15 to move, the fixed plate 15 will drive the support plate 6 to move, and the support plate 6 will abut against the arch 2. The fixed rod 16 will rotate inside the connecting block 17, the fixed rod 16 will drive the fixed plate 15 to rotate, the fixed plate 15 will drive the support plate 6 to rotate, and the rotation of the support plate 6 will allow it to fully fit against the arch 2, thereby supporting the arch 2.

[0030] Both the connecting rod 9 and the fixing rod 16 pass through the connecting block 17. The disassembly part includes a connecting cylinder 21 fixedly installed at the output end of the second drive rod 7. A mounting post 18 is slidably connected inside the connecting cylinder 21. The mounting post 18 is fixedly connected to the connecting block 17 on the fixing rod 16. A second sliding groove 22 is provided on the mounting post 18. A limit bolt 19 is slidably connected inside the second sliding groove 22. A second spring 20 is fixedly installed on the connecting cylinder 21 and the limit bolt 19 passes through the connecting cylinder 21 and is slidably connected to it.

[0031] When it is necessary to replace the support plate 6 with a different size, pulling the limiting bolt 19 will pull the limiting bolt 19 out of the second slide groove 22. The mounting post 18 will no longer be limited, and the support plate 6 will no longer be limited, allowing the support plate 6 to be disassembled. During installation, the mounting post 18 is inserted into the connecting cylinder 21. When the mounting post 18 abuts against the bottom of the connecting cylinder 21, the limiting bolt 19 is exactly opposite to the second slide groove 22. Releasing the limiting bolt 19 will allow it to move into the second slide groove 22. The second spring 20 can ensure the stability of the limiting bolt 19 in the second slide groove 22, thereby ensuring that the mounting post 18 is limited, thus completing the limitation of the support plate 6 and completing the installation of the support plate 6.

[0032] Working principle: When in operation, opening the first drive rod 5 causes the output end of the first drive rod 5 to drive the mounting cylinder 13 to move upward. The mounting cylinder 13 then drives the connecting column 12 to move upward, which in turn drives the support plate 6 to move upward. The support plate 6 moves upward and comes into contact with the arch 2, generating a thrust on the arch 2 and thus supporting it. Opening the second drive rod 7 causes the output end of the second drive rod 7 to drive the connecting cylinder 21 to move. The connecting cylinder 21 then drives the mounting column 18 to move, which in turn drives the connecting block 17 connected to the fixed rod 16 to move. The connecting block 17 then drives the fixed rod 16 to move, which in turn drives the fixed plate 15 to move. The fixed plate 15 then drives the support plate 6 to move, which comes into contact with the arch 2 and thus generates pressure on the arch 2 for support.

[0033] When it is necessary to replace the support plate 6 with a different size, pulling the limiting rod 10 will pull the limiting rod 10 out of the first slide groove 14. The connecting column 12 will no longer be limited, and the support plate 6 will no longer be limited, allowing the support plate 6 to be disassembled. During installation, the connecting column 12 is inserted into the mounting cylinder 13. When the connecting column 12 abuts against the bottom of the mounting cylinder 13, the limiting rod 10 is exactly opposite to the first slide groove 14. Releasing the limiting rod 10 will allow it to move into the first slide groove 14. The first spring 11 ensures the stability of the limiting rod 10 within the first slide groove 14, thereby ensuring that the connecting column 12 is limited, thus completing the limitation of the support plate 6. To install the support plate 6, pull the limiting bolt 19 to pull it out of the second slide groove 22. The mounting post 18 is no longer limited, and the support plate 6 is no longer limited, allowing the support plate 6 to be disassembled. During installation, insert the mounting post 18 into the connecting cylinder 21. When the mounting post 18 abuts against the bottom of the connecting cylinder 21, the limiting bolt 19 is exactly opposite to the second slide groove 22. Release the limiting bolt 19, and it will move into the second slide groove 22. The second spring 20 can ensure the stability of the limiting bolt 19 in the second slide groove 22, thereby ensuring that the mounting post 18 is limited, thus completing the limitation of the support plate 6 and completing the installation of the support plate 6.

[0034] When the support position needs to be changed, move the support plate 6. The support plate 6 will drive the fixed plate 15 to rotate, the fixed plate 15 will drive the connecting block 17 to rotate, the connecting block 17 will drive the connecting cylinder 21 to rotate, the connecting cylinder 21 will drive the second drive rod 7 to rotate, the second drive rod 7 will drive the connecting block 17 connected to the connecting rod 9 to rotate, the connecting block 17 will rotate around the connecting rod 9, open the second drive rod 7, the output end of the second drive rod 7 will drive the connecting cylinder 21 to move, the connecting cylinder 21 will drive the mounting column 18 to move, the mounting column 1... 8 will cause the connecting block 17 connected to the fixed rod 16 to move, the connecting block 17 will cause the fixed rod 16 to move, the fixed rod 16 will cause the fixed plate 15 to move, the fixed plate 15 will cause the support plate 6 to move, the support plate 6 will abut against the arch 2, the fixed rod 16 will rotate within the connecting block 17, the fixed rod 16 will cause the fixed plate 15 to rotate, the fixed plate 15 will cause the support plate 6 to rotate, the support plate 6 can rotate to completely fit with the arch 2, thereby supporting the arch 2.
