[0002] Umbrellas are used to block the sun on sunny days and to block rain on rainy days. They can provide a cool environment or block rain, snow, and sunlight. Umbrellas are usually made of stretchable fabrics and other materials that can be used as frames and winding wires. Automatic umbrellas can be opened and closed by pressing a button on the umbrella handle.

[0003] However, the automatic umbrella has a major disadvantage. Since the ribs are relatively thin and short, and the connection limit of the ribs is achieved close to the hinge points between the ribs, when there is a large wind pressure blowing from bottom to top on the umbrella surface, it is easy for the last section of the ribs to be blown upward, causing the edge of the umbrella to bend upward, causing the user to get wet, and sometimes even causing the ribs to deform or be damaged. Therefore, in order to solve this problem, the present application proposes a new solution. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] A new type of anti-folding automatic umbrella, as Figure 1 shown, includes an umbrella handle 1, a middle rod 2, and an umbrella bone assembly 3 provided on the middle rod 2. The connection manner and specific structure of the umbrella handle 1, the middle rod 2, and the umbrella bone assembly 3 can all adopt the structure of the existing conventional three-fold automatic umbrella. And as Figure 2 shown, the umbrella bone assembly 3 includes a first bone joint 4 at the end and a second bone joint 5 connected to the first bone joint 4. Among them, a first connecting piece 6 and a second connecting piece 7 are respectively provided at both ends of the first bone joint 4. The first bone joint 4 adopts a double-keel structure. The first connecting piece 6 is sleeved at the end of the keel, and the second connecting piece 7 is sleeved at the head end of the keel; a third connecting piece 8 and a fourth connecting piece 9 are respectively provided at both ends of the second bone joint 5. The second bone joint 5 adopts a triple-keel structure. The third connecting piece 8 is sleeved at the end of the keel, and the fourth connecting piece 9 is sleeved at the head end of the keel. The second connecting piece 7 is rotatably connected to the third connecting piece 8.

[0024] As Figure 2 shown, a pull rope 10 is provided on the umbrella bone assembly 3, and both ends of the pull rope 10 are fixed to the first connecting piece 6 and the fourth connecting piece 9 respectively. Therefore, when the umbrella is unfolded, the pull rope 10 will be straightened, thereby restricting the distance between the head end of the second bone joint 5 and the end of the first bone joint 4, pulling the first bone joint 4, and preventing it from folding upwards, achieving the purpose of anti-folding.

[0025] As Figure 2 shown, a limiting mechanism for limiting the pulling rope 10 is provided on the third connecting member 8. The limiting mechanism can limit the middle position of the pulling rope 10 on the third connecting member 8, so that the trajectory of the entire pulling rope 10 will conform to the first joint 4 and the second joint 5, thereby preventing the pulling rope 10 from being wound around the umbrella rib assembly 3 due to relaxation after the umbrella is folded, avoiding affecting the opening of the umbrella, and also ensuring the anti-folding effect; As Figure 3 shown, the limiting mechanism includes a first rope threading groove 11 and a rope winding block 12. The first rope threading groove 11 is provided at one end of the third connecting member 8 close to the second connecting member 7, and the rope winding block 12 is fixedly provided on the third connecting member 8. The middle part of the pulling rope 10 first penetrates into the first rope threading groove 11 from the bottom of the third connecting member 8, then winds around the rope winding block 12, and exits from the other side of the rope winding block 12. Therefore, when the third connecting member 8 moves, it will pull the middle part of the pulling rope 10, so that the pulling rope 10 keeps fitting the first joint 4 and the second joint 5.

[0026] As Figure 2 shown, a tension adjusting assembly 13 for adjusting the tension of the pulling rope 10 is provided on the second joint 5. The user can manually adjust the tension of the pulling rope 10 through the tension adjusting assembly 13, making it pull the first joint 4 tighter or looser, so as to adapt to different needs; As Figure 4 shown, the tension adjusting assembly 13 specifically includes a mounting base 14, a pressing block 15, a cover plate member 16 and a spring 17. Among them, the mounting base 14 penetrates through the second joint 5. A limiting hook for limiting the umbrella rib transmission link is provided at the top of the mounting base 14, and the bottom end is the base of the tension adjusting assembly 13 and is formed with two side walls on the left and right; The cover plate member 16 can be fixed to the mounting base 14 by bonding. The cover plate member 16 is formed with two side walls in the front and back, and an opening is provided in the center; The pressing block 15 is slidably connected to the cover plate member 16. A convex block matching the opening on the cover plate member 16 is formed on the pressing block 15. The convex block can slide and extend outside the opening of the cover plate member 16, and a bottom plate fitting the inner side of the side wall is formed at the bottom. The bottom plate can limit the pressing block 15 between the mounting base 14 and the cover plate member 16; The two ends of the spring 17 are respectively abutted against the mounting base 14 and the pressing block 15. Therefore, under the action of the spring 17, an outward moving force will be maintained on the pressing block 15.

[0027] As Figure 4As shown, a second rope threading groove 18 is provided on the cover plate member 16. The second rope threading groove 18 penetrates through the front and rear sides of the cover plate member 16. The pull rope 10 passes through the second rope threading groove 18 and enters the tension adjustment assembly 13. A third rope threading groove 19 is provided on the pressing block 15. The third rope threading groove 19 penetrates through the convex block of the pressing block 15, and the penetration direction is the same as that of the second rope threading groove 18. When the pull rope 10 passes through the second rope threading groove 18 at one end of the cover plate member 16 and enters the tension adjustment assembly 13, it will enter the third rope threading groove 19 and then pass through the second rope threading groove 18 at the other end of the cover plate member 16 and exit the tension adjustment assembly 13; a number of first spike strips 20 are provided on the top of the second rope threading groove 18 of the cover plate member 16, and a number of second spike strips 21 are provided on the bottom of the third rope threading groove 19 of the pressing block 15. The first spike strips 20 and the second spike strips 21 are arranged facing each other. Due to the action of the spring 17, the pressing block 15 will be pushed upward, thereby clamping the pull rope 10, and the first spike strips 20 and the second spike strips 21 increase the clamping effect.

[0028] When it is necessary to adjust the tightness of the pull rope 10, only need to press the pressing block 15 inward to release the clamping limit on the pull rope 10. At the same time, use the other hand to pull the pull rope 10 from the side close to the head end of the second joint 5, so that the end of the pull rope 10 connected to the first joint 4 becomes tighter or looser. After reaching the required tightness, release the pressing on the pressing block 15 so that the pull rope 10 is clamped and limited again.

[0029] As Figure 5 shown, a first rope threading hole 22 is provided on one side of the top surface of the first connecting member 6, and a first end limiting groove 23 is provided on one side of the bottom surface of the first connecting member 6, and the first end limiting groove 23 is communicated with the first rope threading hole 22. The end of the pull rope 10 will first pass through the first rope threading hole 22 and exit from the first end limiting groove 23. At this time, the end can be directly knotted, and the knot is placed in the first end limiting groove 23 to fix the end of the pull rope 10. Or a block can be fixed on the end of the pull rope 10 so that the block is placed in the first end limiting groove 23 to fix the end of the pull rope 10.

[0030] As Figure 6 shown, a second rope threading hole 24 is provided on one side of the top surface of the fourth connecting member 9, and a second end limiting groove 25 is provided on one side of the bottom surface of the fourth connecting member 9, and the second end limiting groove 25 is communicated with the second rope threading hole 24. The other end of the pull rope 10 will first pass through the second rope threading hole 24 and exit from the second end limiting groove 25. At this time, the end can be directly knotted, and the knot is placed in the second end limiting groove 25 to fix the end of the pull rope 10. Or a block can be fixed on the end of the pull rope 10 so that the block is placed in the second end limiting groove 25 to fix the end of the pull rope 10.
