[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model discloses a three-section folding umbrella rod with a small diameter.

[0025] This utility model provides, for example Figure 1-3The illustrated three-section folding umbrella rod includes a first umbrella rod 1, a second umbrella rod 2, and a third umbrella rod 3. The first umbrella rod 1 has a first groove on one side, the second umbrella rod 2 is slidably disposed within the first groove, and a second groove is provided on one side of each second umbrella rod 2. The third umbrella rod 3 is slidably disposed within the second groove. Both the second umbrella rod 2 and the third umbrella rod 3 have cavities inside, and each cavity has a fixing mechanism. The second umbrella rod 2 and the third umbrella rod 3 are respectively fixedly connected to the corresponding first or second groove via corresponding fixing mechanisms. Rotating rods 4 are rotatably connected to the interiors of both the first and second grooves. Torsion springs 5 ​​are provided at both ends of each rotating rod 4, and connecting wires 6 are wound around the walls of each rotating rod 4. The two connecting wires 6 are respectively fixedly connected to one end of the second umbrella rod 2 and the third umbrella rod 3.

[0026] When the second umbrella rod 2 and the third umbrella rod 3 move out of the corresponding first or second slide groove, they can move the corresponding connecting line 6, which in turn can rotate the corresponding rotating rod 4. Then, each torsion spring 5 is compressed. When the umbrella needs to be retracted, the rebound force of each torsion spring 5 can be used to move the two connecting lines 6 to move the corresponding second umbrella rod 2 and the third umbrella rod 3 into the corresponding first and second slide grooves.

[0027] In order to secure the second umbrella center rod 2 and the third umbrella center rod 3, as follows: Figure 1-3 As shown, the fixing mechanism includes two fixing blocks 7, two stop blocks 8, and two springs 9. Each of the two cavities has a through hole on one side. The two fixing blocks 7 are slidably disposed inside the corresponding through holes. The two stop blocks 8 are fixedly connected to one side of the corresponding fixing blocks 7. The two springs 9 are disposed inside the corresponding cavities. The sidewalls of one end of the first slide groove and the second slide groove are provided with fixing holes. One end of each of the two fixing blocks 7 is semi-circular, and the two fixing blocks 7 are matched with the corresponding fixing holes.

[0028] When the second umbrella rod 2 and the third umbrella rod 3 move, the two fixing blocks 7 can move into the corresponding fixing holes by the rebound force of the corresponding springs 9, thereby fixing the second umbrella rod 2 and the third umbrella rod 3.

[0029] To prevent the second umbrella rod 2 and the third umbrella rod 3 from rotating, such as Figure 2-3 As shown, the outer surfaces of the third umbrella rod 3 and the second umbrella rod 2 are symmetrically provided with limiting grooves. Each limiting groove is slidably provided with a limiting block 10 inside. Each limiting block 10 is fixedly connected to the inner wall of the first sliding groove or the second sliding groove.

[0030] Each limiting block 10 can be used to limit the movement of the second umbrella rod 2 and the third umbrella rod 3, so that they can only move left and right but cannot rotate relative to each other.

[0031] To prevent the two connecting lines 6 from being misaligned, such as Figure 2-3 As shown, baffles 11 are symmetrically fixedly sleeved on the walls of the two rotating rods 4, and each baffle 11 is matched with the corresponding connecting line 6.

[0032] Each baffle 11 prevents the two connecting wires 6 from being misaligned, thereby preventing the two connecting wires 6 from being twisted with the corresponding torsion springs 5 ​​respectively.

[0033] The above description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
