[0032] A second sliding ring 4 is slidably provided on the outer periphery of the bottom of the umbrella pole 1. Multiple fixing frames 41 are evenly fixedly connected to the outer periphery of the second sliding ring 4. A first fixing frame 32 is fixedly connected to the middle of the bottom surface of the first fiber support rod 3. The first fixing frame 32 is rotatably connected to the second fiber support rod 33. The bottom end of the second fiber support rod 33 is rotatably connected to the second fixing frame 34. The second fixing frame 34 is slidably connected to the fixing frame 41. When the second fiber support rod 33 is removed, the second fixing frame 34 is moved. The second fixing frame 34 slides within the fixing frame 41. After the second fixing frame 34 leaves the fixing frame 41, the bottom end of the second fiber support rod 33 can be removed. At this time, the first fiber support rod 3 and the second fiber support rod 33 can be removed and replaced. The disassembly and assembly are convenient and quick.

[0033] Example 2:

[0034] Please see Figure 1-4 This is the second embodiment of the present invention. Based on the previous embodiment, the bottom surface of the fixing block 11 is provided with a plurality of limiting grooves 12 evenly arranged in a ring shape, and the limiting frame 22 is inserted into the limiting groove 12. The cooperation between the limiting frame 22 and the limiting groove 12 can better engage the rotating rod 31, which helps the umbrella rib to operate normally.

[0035] A cylindrical rod 5 is fixedly connected to both sides of the top surface of the first sliding ring 2. A pressing ring 51 is fixedly connected to the top of the cylindrical rod 5. The pressing ring 51 is slidably connected to the top of the umbrella rod 1. The cylindrical rod 5 is slidably connected to the fixing block 11. When the pressing ring 51 is pressed, the pressing ring 51 slides on the umbrella rod 1. The pressing ring 51 drives the cylindrical rod 5 to move. The movement of the cylindrical rod 5 drives the first sliding ring 2 to slide on the umbrella rod 1.

[0036] The fixed block 11 has cylindrical grooves 52 on both sides inside. A circular ring plate 53 is slidably connected inside the cylindrical groove 52. The circular ring plate 53 is fixedly sleeved on the outer circumference of the corresponding cylindrical rod 5. A spring 54 is installed inside the cylindrical groove 52. The top end of the spring 54 is fixedly connected to the bottom surface of the corresponding circular ring plate 53, and the bottom end of the circular ring plate 53 is fixedly connected to the bottom surface of the cylindrical groove 52. The spring 54 is movably sleeved on the outer circumference of the corresponding cylindrical rod 5. When the cylindrical rod 5 moves, it causes the circular ring plate 53 to slide in the cylindrical groove 52. The cooperation between the circular ring plate 53 and the cylindrical groove 52 compresses the spring 54. When the cylindrical rod 5 is no longer under force, the spring 54 uses its elastic force to restore the circular ring plate 53 to its original position. The circular ring plate 53 then causes the cylindrical rod 5 to return to its original position.

[0037] The bottom of the pressing ring 51 is provided with a second threaded rod 55, which passes through the cylindrical rod 5 and is threadedly connected to the top of the umbrella rod 1; the second threaded rod 55 helps to limit the cylindrical rod 5 and ensures that the cylindrical rod 5 will not move when the umbrella ribs are in use.

[0038] The second sliding ring 4 is slidably connected to the limiting ring 42 on its outer periphery. The limiting ring 42 is slidably connected to the fixed frame 41. The top surface of the limiting ring 42 contacts the bottom surface of the second fixed frame 34. The limiting ring 42 is provided with a first threaded rod 43 on its outer periphery. The first threaded rod 43 passes through the limiting ring 42 and is threadedly connected to the second sliding ring 4. The first threaded rod 43 helps to fix the limiting ring 42. The limiting ring 42 can limit the second fixed frame 34 to the top position of the fixed frame 41, ensuring that the second fixed frame 34 will not move during use.

[0039] The bottom of the second sliding ring 4 is threadedly connected to a mounting ring 44; the mounting ring 44 is an operating structure that facilitates user operation.

[0040] The slot at the top of the limiting bracket 22 is U-shaped; the U-shaped slot of the limiting bracket 22 can better engage the rotating rod 31.

[0041] An operating ring 23 is fixedly connected to the bottom surface of the first sliding ring 2; during installation and removal, the operating ring 23 can be used as an auxiliary removal method.

[0042] The top of the fixing block 11 is provided with a top cover 13, which is inserted into the outer periphery of the pressing ring 51. The bottom end of the top cover 13 contacts the top surface of the fixing block 11. The top cover 13 can protect the top component from damage and prevent the component from falling due to user misoperation.

[0043] In use, the user pushes the mounting ring 44 upwards, causing the second fixing frame 34 to move. The second fixing frame 34 then moves the second fiber support rod 33. The bottom end of the second fiber support rod 33 rotates on the second fixing frame 34, while the top end rotates on the first fixing frame 32. Simultaneously, the second fiber support rod 33 moves the first fixing frame 32, which in turn rotates the rotating rod 31 to open. Closing is achieved by reversing these steps. When a first fiber support rod 3 is damaged and needs replacement, the top cover 13 is pulled out upwards, and then the second threaded rod... Remove rod 55, press the pressing ring 51, the pressing ring 51 moves and drives the cylindrical rod 5 to move, the cylindrical rod 5 moves and drives the annular piece 53 to slide in the cylindrical groove 52, the engagement of the annular piece 53 and the cylindrical groove 52 compresses the spring 54, the cylindrical rod 5 moves and drives the first sliding ring 2 and the operating ring 23 to slide on the umbrella rod 1, the first sliding ring 2 moves and drives the limiting frame 22 to move, after the limiting frame 22 moves out of the limiting groove 12, the top of the first fiber support rod 3 moves upward and the first fiber support rod 3 drives the rotating rod 31 to move out of the limiting frame 22, rotate the mounting ring 44 to remove the mounting ring 44, and then remove the first thread. Rod 43 slides downwards, limiting ring 42 moves downwards along second sliding ring 4 and fixed frame 41. After limiting ring 42 moves out of second sliding ring 4, second fiber support rod 33 moves downwards. Second fiber support rod 33 drives second fixed frame 34 to move within fixed frame 41. After second fixed frame 34 slides out of fixed frame 41, removal of first fiber support rod 3 and second fiber support rod 33 is completed. After replacing with new first fiber support rod 3 and second fiber support rod 33, rotating rod 31 is placed into limiting frame 22. Pressing ring 51 is released, and spring 54 uses elasticity to restore ring plate 53 to its original position. The annular plate 53 drives the cylindrical rod 5 to return to its original position, the first sliding ring 2 and the limiting frame 22 return to their original positions, and the limiting frame 22 is inserted into the limiting groove 12 to complete the installation of the top. The bottom second fiber support rod 33 can be operated in the reverse order of the above steps. In this utility model, when any of the first fiber support rods 3 and the first fixing frame 32 on the umbrella rib are damaged, the user does not need to disassemble the entire umbrella rib. With the cooperation of the parts, the first fiber support rod 3 and the rotating rod 31 can be removed with simple operation. The disassembly and assembly are convenient and quick, avoiding the situation of discarding the entire umbrella rib due to partial damage, and greatly reducing maintenance costs.
