The embodiments described below by referring to the drawings are exemplary, only for explaining the utility model, and cannot be understood as the limitation of the utility model.

[0033] Refer toFigures 1-9 In some embodiments, a center pole pulling structure for a canopy includes an outer support frame 1, which is internally provided with a decorative top disc 3, and is provided with a plurality of connecting steel ropes 2, one end of which is connected to the outside of the decorative top disc 3, and the inside of the decorative top disc 3 is provided with a support frame 5, the top of which is provided with a connecting seat 11, the top of which is provided with a movable cavity 12, the inside of which is rotatably connected to a movable end 18, one end of which is provided with a center pole 4, one end of which is used to abut against the top canopy, and the top of the support frame 5 is provided with a pulling seat 23, the inside of which is rotatably connected with a pulling roller 24, the outside of which is wound with a pulling steel rope 21, one end of which is connected with the movable end 18.

[0034] Through the above technical scheme, when the canopy is installed, the decorative top disc 3 is first fixed in the inside of the outer support frame 1 through the plurality of connecting steel ropes 2, at this time the outer canopy cloth is built on the top of the decorative top disc 3, and the center pole 4 is in a placed state on the top of the connecting seat 11, when the pulling roller 24 rotates, the pulling roller 24 drives the pulling steel rope 21 to be wound, since one end of the pulling steel rope 21 is connected with the movable end 18, the movable end 18 drives the center pole 4 to rotate, so that the center pole 4 is in a vertical state, then it will abut against the canopy cloth on the top, the worker only needs to operate the pulling roller 24, so that the center pole 4 can be easily lifted to a predetermined position, without the need for complex operation or the assistance of large mechanical equipment, which simplifies the installation mode of the center pole 4.

[0035] In addition, when the center pole 4 is in a vertical state, since the top of the center pole 4 will abut against the canopy cloth, the canopy cloth provides a large friction force to the center pole 4, so that the center pole 4 will not collapse, but in order to improve the safety factor, a fixed structure is usually arranged on one side of the movable end 18.

[0036] Reference Figure 6 In some embodiments, a first fixing hole 13 is formed on one side of the movable end 18, a second fixing hole 14 is formed on one side of the connecting seat 11, the second fixing hole 14 is located in the middle of the connecting seat 11, a first fixing bolt 15 is arranged in the second fixing hole 14, and the first fixing bolt 15 is threadedly matched with the first fixing hole 13.

[0037] Through the above technical scheme, when the center pole 4 is in a vertical state, the movable end 18 can be fixed on the connecting seat 11 through the thread matching of the first fixing bolt 15 and the first fixing hole 13, which provides stable support for the center pole 4, and the first fixing hole 13 and the first fixing bolt 15 in the middle position are designed to help evenly distribute the force, reducing the distortion or deformation caused by uneven bearing.

[0038] ReferenceFigure 6 In some embodiments, two third fixing holes 16 are formed on one side of the connecting seat 11, and the two third fixing holes 16 are located on the two sides of the second fixing hole 14, so that the two third fixing holes 16 are close to the support frame 5. A second fixing bolt 17 is arranged in the third fixing hole 16. When the first fixing bolt 15 is separated from the first fixing hole 13, the second fixing bolt 17 is threadedly connected with any one of the third fixing holes 16.

[0039] Through the above technical scheme, when the central support rod 4 is transversely placed, the second fixing bolt 17 is threadedly connected with the first fixing hole 13, so that the decorative top disc 3 is fixed in the inside of the outer support frame 1 by the plurality of connecting steel ropes 2, and the movable end 18 of the central support rod 4 cannot rotate, thereby avoiding that the movable end 18 of the central support rod 4 interferes with the erection of the decorative top disc 3.

[0040] Referring to Figure 7 In some embodiments, the traction roller 24 is provided with a first transmission gear 26 on one side, the traction seat 23 is rotatably connected with a first rotating shaft 30 and a second rotating shaft 31 inside, the first rotating shaft 30 is located between the second rotating shaft 31 and the first transmission gear 26, the first rotating shaft 30 is provided with a second transmission gear 29 and a third transmission gear 27 outside, the second transmission gear 29 is engaged with the first transmission gear 26, the second rotating shaft 31 is provided with a fourth transmission gear 28 outside, the third transmission gear 27 is engaged with the fourth transmission gear 28, the traction seat 23 is rotatably connected with a traction rotating shaft 41 on one side, the traction rotating shaft 41 is coaxially transmitted with the second rotating shaft 31, and the traction rotating shaft 41 is provided with a movable handle 22 at one end.

[0041] Through the above technical scheme, when the operator rotates the movable handle 22, power is transmitted to the second rotating shaft 31 through the traction rotating shaft 41, the second rotating shaft 31 drives the fourth transmission gear 28 to rotate, and then transmits power to the third transmission gear 27, the third transmission gear 27 transmits power to the second transmission gear 29, and finally the second transmission gear 29 transmits power to the first transmission gear 26, the first transmission gear 26 is connected with the traction roller 24, so as to rotate the traction roller 24, realize the winding of the traction steel rope 21, and through the use of a plurality of gears, the whole transmission system can be designed to be more compact, and is suitable for installation in a limited space such as a tent for operation.

[0042] Referring to Figure 7 In some embodiments, the traction rotating shaft 41 is provided with a brake gear 32 outside, the traction seat 23 is rotatably connected with a plurality of third rotating shafts 35 on one side, the third rotating shaft 35 is provided with a fixed movable block 33 at one end, the fixed movable block 33 is provided with a brake convex tooth 34 at one end, the brake convex tooth 34 is elastically connected with the traction seat 23, and the brake convex tooth 34 is engaged with the brake gear 32.

[0043] By the above technical scheme, when the traction roller 24 is rotating, if the traction action is suddenly stopped, the center support rod 4 will start to descend due to the action of gravity. The descending force will be transmitted to the traction roller 24 through the connecting cable 2. At this time, the gravity of the center support rod 4 will drive the traction roller 24 to rotate in the opposite direction. The plurality of brake teeth 34 are elastically connected with the traction seat 23, and the brake teeth 34 are meshed with the brake gear 32. This connection allows the brake teeth 34 to displace when subjected to external force, but is always subjected to the action of the elastic force, so that the traction roller 24 needs to overcome the elasticity of the plurality of brake teeth 34 when rotating, which means that the reverse rotation of the traction roller 24 will be significantly slowed down, because each brake tooth 34 needs to be overcome one by one, thereby absorbing and dispersing the energy generated when the center support rod 4 descends, ensuring that the reverse rotation of the traction roller 24 is a smooth deceleration process, rather than a sudden stop, which helps to protect the transmission system from damage.

[0044] In addition, when the traction roller 24 is normally traction, the elasticity of the brake teeth 34 also needs to be overcome. Although more force is needed when the traction roller 24 rotates, this continuous resistance helps to prevent the traction roller 24 from rapidly rotating in the opposite direction due to the sudden disappearance of external force (such as the operator releasing the handle).

[0045] Referring to Figure 7 In some embodiments, the third rotating shaft 35 is externally sleeved with a reset torsional spring 37, one end of the reset torsional spring 37 is provided with a first leg 38, the outside of the traction seat 23 is provided with a plurality of limiting holes 36, the first leg 38 is clamped with the adjacent limiting hole 36, one side of the brake tooth 34 is provided with a connecting block 40, the other end of the reset torsional spring 37 is provided with a second leg 39, and the second leg 39 abuts against the connecting block 40.

[0046] By the above technical scheme, the limiting hole 36 and the connecting block 40 limit the rotation range of the reset torsional spring 37, preventing the reset torsional spring 37 from being stretched or compressed excessively, thereby protecting the reset torsional spring 37 from being damaged.

[0047] Referring to Figures 3-5 In some embodiments, one end of the center support rod 4 is provided with a supporting block 6, the shape of the supporting block 6 is a cone, and the supporting block 6 is used to abut against the tarpaulin.

[0048] By the above technical scheme, the abutment of the conical supporting block 6 and the tarpaulin can effectively maintain the circular or arched structure of the tent, and the concentrated pressure point helps to improve the stability of the tent, especially in the case of strong wind or additional load, which can reduce the swing and vibration of the tarpaulin; and due to the small contact area, compared with a flat or larger area contact point, the conical supporting block 6 has less wear on the tarpaulin, which helps to prolong the service life of the tarpaulin.

[0049] Referring to Figures 3-5 In some embodiments, the center pole 4 is provided with a mounting slot 7 at one end, and the top support block 6 is provided with a mounting column 8 at one side, which is inserted into the mounting slot 7.

[0050] Through the above technical solution, the insertion mode enables the top support block 6 to be quickly and easily installed on the center pole 4, and also enables the top support block 6 to be quickly removed when needed. In addition, the close fit between the mounting column 8 and the mounting slot 7 ensures the stability of the top support block 6 on the center pole 4, reducing displacement under the action of wind or other external forces.

[0051] Referring to Figures 3-5 In some embodiments, the mounting column 8 is provided with a first connecting hole 9 on the outside, and the center pole 4 is provided with a second connecting hole 10 on the outside at one end, which corresponds to the first connecting hole 9.

[0052] Through the above technical solution, when the top support block 6 is inserted into the mounting slot 7 of the center pole 4, the first connecting hole 9 and the second connecting hole 10 can be aligned, and an external screw can be inserted to fix the position of the top support block 6.

[0053] Referring to Figure 6 In some embodiments, the other side of the movable end 18 is provided with a fixed ring 19, and one end of the traction cable 21 is provided with a fixed hook 20, which is hooked with the inside of the fixed ring 19.

[0054] Through the above technical solution, the fixed hook 20 can be quickly hooked into and separated from the fixed ring 19, and the operator can easily connect or disconnect the traction cable 21, especially when the tent structure needs to be adjusted or moved.

[0055] It should be noted that, in this document, relational terms such as first and second and the like can be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises", "comprising", or any other variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus.
