[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] Example 1

[0030] like Figures 1-4 As shown, an outdoor sunshade umbrella includes an umbrella column 1 and a handrail assembly 2 mounted on the umbrella column 1. The handrail assembly 2 slides up and down along the umbrella column 1 and locks at any position on the umbrella column 1. One end of the handrail assembly 2 is hinged to a diagonal rod 3. A reinforcing member is hinged to the top of the umbrella column 1. One end of the reinforcing member is hinged to the middle of the diagonal rod 3. The reinforcing member includes two first pull rods 4 and a second pull rod 5. The second pull rod 5 is located between the two first pull rods 4. One end of each of the two first pull rods 4 is hinged to both ends of a tube fitting 6 mounted on the diagonal rod 3. The other ends of each of the two first pull rods 4 are hinged to both ends of a fixing seat 7 fixed to the top of the umbrella column 1. One end of the second pull rod 5 is fixed to a connecting block 8. The two ends of the connecting block 8 are hinged to symmetrically arranged connecting rods 9. One end of each of the two connecting rods 9 is hinged to two corresponding first pull rods 4. The other end of the second pull rod 5 is hinged to the fixing seat 7.

[0031] It also includes an upper umbrella plate 10, a lower umbrella plate 11, and long umbrella ribs 12 and short umbrella ribs 13 that are fitted onto the upper umbrella plate 10 and the lower umbrella plate 11. The end of the diagonal rod 3 away from the umbrella post 1 is hinged to the upper umbrella plate 10. The short umbrella ribs 13 are arranged one-to-one with the long umbrella ribs 12. The long umbrella ribs 12 and the diagonal rod 3 are arranged evenly around the upper umbrella plate 10, and the short umbrella ribs 13 are arranged evenly around the lower umbrella plate 11. One end of the short umbrella rib 13... The upper umbrella plate 10 is hinged to the lower umbrella plate 11 at one end and to the middle of the corresponding long umbrella rib 12 at the other end. A support rod 14 is provided on the bottom end face of the upper umbrella plate 10. The bottom of the support rod 14 is movably inserted into the lower umbrella plate 11. When the umbrella frame is open, the lower umbrella plate 11 and the support rod 14 are inserted into each other. When the umbrella frame is closed, the lower umbrella plate 11 and the support rod 14 are separated. A counterweight base 15 is fixed at the bottom of the umbrella column 1. A protective sleeve 16 is fitted at the end of each long umbrella rib 12.

[0032] The specific working principle of Embodiment 1 of this utility model is as follows:

[0033] After the handrail assembly 2 slides along the umbrella column 1 to the required height, it is frictionally locked and fixed to the umbrella column 1. The diagonal rod 3 is hinged to the reinforcement at the top of the umbrella column 1 to form a triangular stable frame. When the umbrella surface is exposed to wind, the wind force is transmitted to the reinforcement through the diagonal rod 3. The first pull rod 4 distributes the tension to the umbrella column 1. The second pull rod 5 balances the stress on both sides (the two first pull rods 4) through the connecting block 8 and the two symmetrically arranged connecting rods 9 to avoid unilateral overload.

[0034] By setting up a reinforcing component, which consists of two first pull rods 4 (main force bearing) and one second pull rod 5 (auxiliary), the handrail assembly 2 is hinged to the diagonal rod 3, and the top of the umbrella column 1 is hinged to the middle of the diagonal rod 3 through the reinforcing component to form a triangular support structure. The triangular hinge structure disperses the force on the umbrella surface, and the reinforcing component converts the lateral wind force into the axial pressure of the umbrella column 1, effectively dispersing the force on the diagonal rod 3, improving the strength and stability of the sun umbrella, and improving the windproof performance of the sun umbrella.

[0035] Example 2

[0036] like Figures 5-6 As shown, two symmetrically arranged rotating shafts 17 are fixed on the connecting block 8. The connecting rod 9 has a circular hole 18 for the rotating shafts 17 to be fitted into. The connecting rod 9 is rotatably connected to the rotating shafts 17 through the circular hole 18. The connecting block 8 has two symmetrically arranged first annular grooves 22. A first annular boss 23 is formed on the inner side of the first annular groove 22. The two rotating shafts 17 are respectively fixed to one end of the corresponding two first annular bosses 23. A torsion spring 19 is sleeved on the first annular boss 23. One end of the torsion spring 19 abuts against the inner wall of the first annular groove 22. One end of the connecting rod 9 has a second annular groove 24. A second annular protrusion 25 is formed on the inner side of 24. Two circular holes 18 are respectively set on the corresponding two second annular protrusions 25. The other end of the torsion spring 19 is sleeved on the second annular protrusion 25. The torsion arm at the other end of the torsion spring 19 abuts against the inner wall of the second annular groove 24. Using a special tool, the two ends of the torsion spring 19 are pressed into the inner walls of the first annular groove 22 and the second annular groove 24 respectively (5~8kg pre-tightening force needs to be applied). The connecting rod 9 has a circular groove 20. The circular hole 18 is connected to the circular groove 20. A circular block 21 is embedded in the circular groove 20. The rotating shaft 17 passes through the circular hole 18 and extends into the circular groove 20. One end is fixed to the circular block 21.

[0037] The specific working principle of Embodiment 2 of this utility model is as follows:

[0038] The torsion spring 19 is sleeved on the first annular boss 23 and the second annular boss 25, and the two ends thereof are fixed to the inner walls of the first annular groove 22 and the second annular groove 24 respectively, so as to form a constant pre-tightening torque.

[0039] The folding state: the connecting rod 9 is rotated around the rotating shaft 17 under the action of tension, and the torsion spring 19 stores energy;

[0040] The unfolding state: after the external force disappears, the torsion spring 19 releases energy and drives the connecting rod 9 to return to the initial angle.

[0041] By setting the torsion spring 19 with a certain pre-tightening force, the torsion spring 19 realizes elastic return through the connecting rod 9, reduces the operation resistance, and facilitates the operator to unfold the sunshade umbrella more labor-savingly.

[0042] Although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the description manner of the specification is only for the sake of clarity, and the person skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments which can be understood by the person skilled in the art.
