[0045] Example 1

[0046] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, this embodiment provides an umbrella pole structure, including a plurality of umbrella tubes connected in sequence, an upper nest 101 disposed at the top of the outermost umbrella tube 10, a lower nest 102 slidably disposed on the outermost umbrella tube 10, and an umbrella handle (not shown in the figure) disposed at the bottom of the innermost umbrella tube 12. A cord winder 13 is disposed inside the umbrella handle, and a retractable umbrella cord 14 is disposed between the cord winder 13 and the lower nest 102. A push rod 111 is fixedly disposed on the middle umbrella tube 11, and at least one fixed pulley 12 is disposed on the tube plug of the innermost umbrella tube 12. 1. One end of the push rod pull rope 15 is wound around the rope winder 13, and the other end passes through the fixed pulley 121 and is connected to the push rod 111; the plug of the middle umbrella tube 11 is provided with a first middle tube pulley 112, one end of the outer tube pull rope 16 is connected to the innermost umbrella tube 12, and the other end passes through the first middle tube pulley 112 and is connected to the outermost umbrella tube 10; the upper nest 101 is provided with a first upper nest pulley 1011, one end of the umbrella opening pull rope 17 is connected to the innermost umbrella tube 12, and the other end passes through the first upper nest pulley 1011 and is connected to the lower nest 102.

[0047] Specifically, the middle umbrella tube 11 can be one or more sections, the push rod pull rope 15 and the umbrella closing pull rope 14 are independently set pull ropes, and the rope winder 13 has the function of winding and unwinding the push rod pull rope 15 and the umbrella closing pull rope 14.

[0048] When the umbrella opens, the cord winder 13 rotates counterclockwise, winding up the push rod pull cord 15. This causes the push rod pull cord 15 to pull the push rod 111 upward along the fixed pulley 121. The middle umbrella tube 11 moves upward synchronously under the drive of the push rod 111. At the same time, the outer tube pull cord 16 is driven by the first middle tube pulley 112 to pull the outermost umbrella tube 10, thus extending the umbrella tube. Simultaneously, the lower canopy 102 moves upward under the drive of the opening pull cord 17, thus opening the umbrella canopy.

[0049] When closing the umbrella, the cord winder 13 rotates clockwise, winding the umbrella closing cord 14, which pulls the lower umbrella housing 102 downwards, thus closing the umbrella canopy. Simultaneously, the opening cord 17 is driven by the lower umbrella housing 102, engaging the outermost umbrella tube 10 with the middle umbrella tube 11. At the same time, the outer tube cord 16 engages the middle umbrella tube 11 with the innermost umbrella tube 12, achieving umbrella tube retraction. Simultaneously, the push rod 111 moves downwards towards the cord winder 13, following the middle umbrella tube 11.

[0050] Thus, the wiring design of the umbrella pole structure simplifies the opening and closing operation of the umbrella. By simply controlling the rotation of the rope winder 13, the extension and retraction of the umbrella tube can be synchronized with the umbrella surface, making the operation of the umbrella more effortless and improving the convenience of using the umbrella. This allows users to experience a smoother and more convenient user experience in daily use.

[0051] In this embodiment, two fixed pulleys 121 are provided, and a movable pulley 1111 is provided on the push rod 111. The other end of the push rod pull rope 15 is connected to the push rod 111 along one fixed pulley 121, the movable pulley 1111, and the other fixed pulley 121. In this way, the load can be shared by the cooperation of the movable pulley 1111 and the fixed pulley 121, thereby reducing the force acting on the push rod 111. The push rod 111 only needs to move a certain distance for the lower nest 102 to achieve a large displacement. In this embodiment, the moving distance of the push rod 111 is only 1 / 3 of the moving distance of the lower nest 102. For example, to move the lower nest 102 upward by 15cm, it is only necessary to pull the push rod 111 upward by 5cm, making the operation more labor-saving.

[0052] In this embodiment, a lower nest pulley 1021 is provided on the lower nest 102, which is located on the same side as the first upper nest pulley 1011. The other end of the parachute opening pull rope 17 is connected to the first upper nest pulley 1011 along the first upper nest pulley 1011 and the lower nest pulley 1021. By providing the lower nest pulley 1021 on the lower nest 102, the movement path of the parachute opening pull rope 17 can be further controlled and guided, making the path of the parachute opening pull rope 17 pulling the lower nest 102 more stable, and making it easier for the parachute opening pull rope 17 to pull the lower nest 102, thereby improving the operational efficiency of the parachute opening operation.

[0053] In this embodiment, an elastic element 18 is provided between the umbrella retractor cord 14 and the lower nest 102. The elastic element 18 can be a spring or an elastic band. Since the tension of the cords varies, the elastic element 18 can adaptively adjust the cord tension and compensate for changes in cord length, ensuring that each cord is subjected to uniform force and maintaining overall balance and coordination.

[0054] Example 2

[0055] like Figure 1 and Figure 2 As shown, in this embodiment, a second upper nest pulley 1012 is provided on the upper nest 101, and an outer tube pulley 103 on the outermost umbrella tube 10 is provided on the same side as the second upper nest pulley 1012; one end of the umbrella pulling rope 14 is connected to the lower nest 102 along the second upper nest pulley 1012 and the outer tube pulley 103.

[0056] Specifically, when the umbrella opens, the cord winder 13 rotates counterclockwise, winding up the push rod pull cord 15. This causes the push rod pull cord 15 to pull the push rod 111 upward along the fixed pulley 121. The middle umbrella tube 11 moves upward synchronously under the drive of the push rod 111. At the same time, the outer tube pull cord 16 is driven by the first middle tube pulley 112 to pull the outermost umbrella tube 10, thus extending the umbrella tube. Simultaneously, the lower canopy 102 moves upward under the drive of the opening pull cord 17, thus opening the umbrella canopy.

[0057] When closing the umbrella, the cord winder 13 rotates clockwise to wind up the umbrella closing cord 14, causing the closing cord 14 to pull the lower umbrella tube 102 downwards along the second upper umbrella tube pulley 1012 and the outer tube pulley 103, thus closing the umbrella canopy. Simultaneously, the opening cord 17 is driven by the lower umbrella tube 102, engaging the outermost umbrella tube 10 with the middle umbrella tube 11. At the same time, the outer tube cord 16 engages the middle umbrella tube 11 with the innermost umbrella tube 12, thus retracting the umbrella tubes. Simultaneously, the push rod 111 moves downwards towards the cord winder 13, following the middle umbrella tube 11.

[0058] Example 3

[0059] like Figure 3 and Figure 4 As shown, in this embodiment, the umbrella retractor 14 includes a first retractor 141 and a second retractor 142. An outer tube pulley 103 is provided on the outermost umbrella tube 10. The first retractor 141 is located between the retractor 13 and the upper nest 101. One end of the second retractor 142 is connected to the middle umbrella tube 11, and the other end of the second retractor 142 is connected to the lower nest 102 along the outer tube pulley 103.

[0060] Specifically, when the umbrella opens, the cord winder 13 rotates counterclockwise, winding up the push rod pull cord 15. This causes the push rod pull cord 15 to pull the push rod 111 upward along the fixed pulley 121. The middle umbrella tube 11 moves upward synchronously under the drive of the push rod 111. At the same time, the outer tube pull cord 16 is driven by the first middle tube pulley 112 to pull the outermost umbrella tube 10, thus extending the umbrella tube. Simultaneously, the lower canopy 102 moves upward under the drive of the opening pull cord 17, thus opening the umbrella canopy.

[0061] When closing the umbrella, the cord winder 13 rotates clockwise, winding the first pull cord 141, which pulls the outermost umbrella tube 10 to engage with the middle umbrella tube 11. Simultaneously, the outer tube pull cord 16 drives the middle umbrella tube 11 to engage with the innermost umbrella tube 12, thus retracting the umbrella tubes. At the same time, the second pull cord 142 is synchronously driven by the outer tube pulley 103 located on the outermost umbrella tube 10, thereby pulling the lower canopy 102 downward, closing the umbrella surface. Simultaneously, the push rod 111 moves downward along with the middle umbrella tube 11 towards the cord winder 13.

[0062] Example 4

[0063] like Figure 5 and Figure 6 As shown, in this embodiment, a second middle tube pulley 113 is provided on the tube plug of the middle umbrella tube 11, and an outer tube pulley 103 on the same side as the second middle tube pulley 113 is provided on the outermost umbrella tube 10; one end of the umbrella retractor rope 14 is connected to the lower nest 102 along the second middle tube pulley 113 and the outer tube pulley 103.

[0064] Specifically, when the umbrella opens, the cord winder 13 rotates counterclockwise, winding up the push rod pull cord 15. This causes the push rod pull cord 15 to pull the push rod 111 upward along the fixed pulley 121. The middle umbrella tube 11 moves upward synchronously under the drive of the push rod 111. At the same time, the outer tube pull cord 16 is driven by the first middle tube pulley 112 to pull the outermost umbrella tube 10, thus extending the umbrella tube. Simultaneously, the lower canopy 102 moves upward under the drive of the opening pull cord 17, thus opening the umbrella canopy.

[0065] When closing the umbrella, the cord winder 13 rotates clockwise to wind up the umbrella closing cord 14, causing the closing cord 14 to pull the lower umbrella tube 102 downwards along the second middle tube pulley 113 and the outer tube pulley 103, thus closing the umbrella canopy. Simultaneously, the opening cord 17 is driven by the lower umbrella tube 102, engaging the outermost umbrella tube 10 with the middle umbrella tube 11. At the same time, the outer tube cord 16 engages the middle umbrella tube 11 with the innermost umbrella tube 12, thus retracting the umbrella tubes. Simultaneously, the push rod 111 moves downwards towards the cord winder 13, following the middle umbrella tube 11.

[0066] Example 5

[0067] like Figure 7 and Figure 8 As shown, in this embodiment, an inner tube pulley 122 is provided on the plug of the innermost umbrella tube 12, a third middle tube pulley 114 is provided on the middle umbrella tube 11, a second upper nest pulley 1012 is provided on the upper nest 101, and an outer tube pulley 103 is provided on the outermost umbrella tube 10; the inner tube pulley 122, the third middle tube pulley 114, the second upper nest pulley 1012, and the outer tube pulley 103 are arranged on the same side; the umbrella closing pull rope 14 includes a first rope segment 14. 3. The second rope segment 144 and the third rope segment 145; the first rope segment 143 is set between the rope winder 13 and the push rod 111, the second rope segment 144 is set between the rope winder 13 and the middle umbrella tube 11, one end of the third rope segment 145 is set on the middle umbrella tube 11, and the other end of the third rope segment 145 is connected to the lower nest 102 along the inner tube pulley 122, the third middle tube pulley 114, the second upper nest pulley 1012, and the outer tube pulley 103.

[0068] Specifically, when the umbrella opens, the cord winder 13 rotates counterclockwise, winding up the push rod pull cord 15. This causes the push rod pull cord 15 to pull the push rod 111 upward along the fixed pulley 121. The middle umbrella tube 11 moves upward synchronously under the drive of the push rod 111. At the same time, the outer tube pull cord 16 is driven by the first middle tube pulley 112 to pull the outermost umbrella tube 10, thus extending the umbrella tube. Simultaneously, the lower canopy 102 moves upward under the drive of the opening pull cord 17, thus opening the umbrella canopy.

[0069] When closing the umbrella, the rope winder 13 rotates clockwise, winding the first rope segment 143 and the second rope segment 144. The first rope segment 143 pulls the push rod 111, causing the middle umbrella tube 11 to move downwards, engaging with the innermost umbrella tube 12. Simultaneously, the second rope segment 144 pulls the middle umbrella tube 11 downwards, further accelerating the engagement speed. The outer tube pull rope 16 then pulls the outermost umbrella tube 10 to engage with the middle umbrella tube 11, achieving the retraction of the umbrella tubes. Simultaneously, the third rope segment 145 is synchronously driven by the third middle tube pulley 114 located on the middle umbrella tube 11, pulling the lower canopy 102 downwards along the inner tube pulley 122, the third middle tube pulley 114, the second upper canopy pulley 1012, and the outer tube pulley 103, thus closing the umbrella canopy. At the same time, the push rod 111 moves downwards along with the middle umbrella tube 11 toward the rope winder 13.
