[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5This utility model discloses a self-adjusting wind-resistant umbrella frame, including an umbrella rib shaft 1, support strips 2, and an umbrella fabric 18. Eight support strips 2 are evenly distributed and rotatably connected around the umbrella rib shaft 1. The umbrella fabric 18 is tied to the surface of the support strips 2 by ropes. The eight support strips 2 are assembled such that when the umbrella rib shaft 1 rotates to the top position, the support strips 2 press against the umbrella fabric 18 and open it. The frame also includes a tension strip 3 rotatably connected to one end of each support strip 2. An adjusting rod 4 is rotatably connected to the surface of the tension strip 3. One end of the adjusting rod 4 is rotatably connected to the inside of a support block 5, and the other end inside the support block 5 is rotatably connected to a reinforcing strip 6. The frame is designed to be tensioned and then adjusted. The combined arrangement of the tension bar 3, the adjusting rod 4, and the reinforcing bar 6 strengthens the overall structural strength of the edge frame of the umbrella fabric 18 and improves its wind resistance. One end of the reinforcing bar 6 is rotatably connected to the outer surface of the support bar 2. The adjusting bolt 7, which is threaded and rotates on the surface of the receiving block 5, increases the tension of the umbrella fabric 18. It can also be precisely adjusted manually according to the scale, making the adjustment method convenient and flexible. The adjusting bolt 7 has a scale groove 8 in the middle of its surface, and the surface of the scale groove 8 is engraved with millimeter scale lines. The bottom of the adjusting bolt 7 is rotatably connected to the surface of the support bar 2 near the tension bar 3.

[0025] Specifically, a pressure-absorbing plate 9 is fixedly connected to one end of the umbrella rib shaft 1, and a central umbrella rod 10 is fixedly connected to the middle of one end of the umbrella rib shaft 1. A limiting pressure sleeve 11 is slidably connected to the surface of the central umbrella rod 10. An adjusting main shaft 12 is fixedly connected to the top of the limiting pressure sleeve 11. Eight pressure strips 13 are evenly distributed and rotatably connected around the adjusting main shaft 12. The eight pressure strips 13 are slidably connected to the inside of the support bar 2.

[0026] In this embodiment, when the umbrella fabric 18 is opened, the limiting and pressing sleeve 11 moves upward. After moving to the designated position, the adjusting main shaft 12 drives the eight pressing strips 13 to slide on the support strip 2 respectively, thereby unfolding the support strip 2 and making the support strip 2 open the umbrella fabric 18. This structure is simple and convenient to open.

[0027] Specifically, the bottom end of the umbrella rod 10 is fitted with an umbrella handle 14, and the surface of the umbrella handle 14 is engraved with anti-slip texture.

[0028] In this embodiment, the umbrella handle 14 with anti-slip texture is provided to increase the friction of holding the umbrella handle 14 and prevent slippage.

[0029] Specifically, a limiting pressure plate 19 is provided on the surface of the umbrella rod 10 near the pressure buffer plate 9. The limiting pressure plate 19 is assembled to limit and fix the bottom end of the limiting pressure sleeve 11 when it slides to the pressure buffer plate 9.

[0030] In this embodiment, when the limiting and pressing sleeve 11 slides on the umbrella rod 10 to the pressing buffer plate 9, the limiting and pressing plate 19 is first squeezed by the limiting and pressing sleeve 11, and elastically contracts into the umbrella rod 10. When it is no longer under force, the limiting and pressing plate 19 recovers and limits the bottom end of the limiting and pressing sleeve 11, which plays the role of opening and fixing the umbrella.

[0031] Specifically, the top of the umbrella rod 10 is fixedly connected to the umbrella head 15, and the top of the umbrella head 15 is provided with an arc-shaped rubber flexible joint 16.

[0032] In this embodiment, the use of a flexible joint 16 made of arc-shaped rubber material prevents the umbrella tip 15 from being too sharp and poking people.

[0033] Specifically, an installation cap 17 is sewn onto the edge of the umbrella fabric 18 by a thread, and the inside of the installation cap 17 is inserted into the top of the tension strip 3;

[0034] There are eight mounting caps 17, which are evenly distributed in a circular matrix along the edge of the umbrella fabric 18.

[0035] In this embodiment, the installation of the cap 17 serves to evenly fix the umbrella fabric 18.

[0036] The working principle and usage process of this utility model: When the umbrella fabric 18 is opened, the limiting and pressing sleeve 11 moves upward. After moving to the designated position, the adjusting main shaft 12 drives the eight pressing strips 13 to slide on the support strip 2 respectively, thereby unfolding the support strip 2 so that the support strip 2 can open the umbrella fabric 18. At this time, the tension strip 3, adjusting rod 4, reinforcing strip 6 and the support strip 2 together form a triangular support.

[0037] Then, according to the millimeter scale line on the scale groove 8, the adjusting bolt 7 is rotated to make the receiving block 5 move to the designated position. When the receiving block 5 moves to the adjustment position of the adjusting bolt 7, the adjusting rod 4 pulls the tension bar 3 to retract inward, so that the edge of the umbrella cloth 18 is tightened, and the tension is adjusted.

[0038] In summary, the self-adjusting wind-resistant frame of the umbrella fabric 18, through the combined arrangement of tension bar 3, adjusting rod 4, and reinforcing bar 6, allows the eight pressure bars 13 to slide and open correspondingly inside the support bar 2 when the umbrella fabric 18 is opened, simultaneously driving the tension bar 3 to open the umbrella fabric 18. At this time, the tension bar 3, adjusting rod 4, reinforcing bar 6, and supporting bar 2 form a triangular support, strengthening the overall structural strength of the edge frame of the umbrella fabric 18 and improving wind resistance. Through the setting of adjusting bolt 7, according to the millimeter scale line on the scale groove 8, the adjusting bolt 7 is rotated to move the receiving block 5 to the designated position. When the receiving block 5 moves to the adjustment position of the adjusting bolt 7, the adjusting rod 4 pulls the tension bar 3 inward to contract, tightening the edge of the umbrella fabric 18 and increasing the tension of the umbrella fabric 18. At the same time, it can be precisely adjusted according to the scale and manually, making the adjustment method convenient and flexible.
