DETAILED DESCRIPTION

[0027] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0028] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.

[0029] This embodiment relates to a connection structure of a folding umbrella rib, such as Figure 1-5 As shown, it includes: a first umbrella rib 1, a second umbrella rib 2 and an umbrella rib connecting member 3.

[0030] The rib connector 3 is arranged between the first rib 1 and the second rib 2 to connect the first rib 1 and the second rib 2 and realize the folding effect of the ribs. A first connecting portion 4 for connecting the first rib 1 is arranged at one end of the rib, and a second connecting portion 5 for connecting the ribs is arranged at the other end, so that the first rib 1 and the second rib 2 are connected through the rib connector 3.

[0031] One end of the first umbrella rib 1 is rotatably connected to the first connecting portion 4 of the umbrella rib connecting member 3, so that the first umbrella rib 1 can be rotated relative to the umbrella rib connecting member 3 to achieve a folding effect. An upwardly protruding buckle strip 41 is provided on the first connecting portion 4, and the buckle strip 41 is provided parallel to the first umbrella rib 1. Correspondingly, a buckle groove 11 is provided on the first umbrella rib 1 to match the buckle strip 41, and the mutually buckled state of the buckle groove 11 and the buckle strip 41 corresponds to the unfolded state of the folding umbrella rib. The first umbrella rib 1 and the umbrella rib connecting member 3 are stably connected by the mutual buckle of the buckle groove 11 and the buckle strip 41, so as to reduce the clearance between the first umbrella rib 1 and the umbrella rib connecting member 3 in the left-right direction, avoid the left-right shaking between the first umbrella rib 1 and the umbrella rib connecting member 3, ensure the stability of the folding umbrella rib when in the unfolded state, and improve the wind resistance of the umbrella rib. As a preferred solution, the snap-fit ​​groove 11 is extended along the length direction of the first rib 1, so that the snap-fit ​​area between the snap-fit ​​groove 11 and the snap-fit ​​strip 41 is larger, which can make the first rib 1 more stably connected to the first connecting part 4 and better avoid left and right shaking between the first rib 1 and the rib connecting part 3.

[0032] In the utility model, the cross section of the first umbrella rib 1 is n-shaped, and the buckle groove 11 is set at the inner side of the lower part of the first umbrella rib 1. The umbrella rib with an n-shaped cross section has good bending resistance, can better resist bending deformation when there is external force, improve the wind resistance of the umbrella rib, and ensure the stability and safety of the umbrella rib structure. As a preferred solution, blocking walls 42 are set on both sides of the buckle strip 41 on the first mounting portion to form a fixing groove between the blocking walls 42 on both sides, and the fixing groove is matched with the outer side of the first umbrella rib 1. The blocking walls 42 on both sides clamp the first umbrella rib 1 in the middle, further increasing the connection stability between the first umbrella rib 1 and the umbrella rib connector 3, so that it is not easy to shake between the first umbrella rib 1 and the umbrella rib connector 3.

[0033] The second rib 2 is fixedly connected to the second mounting portion at the other end of the rib connector 3. In this embodiment, the second connecting portion 5 is set as a sleeve hole, and the second rib 2 is sleeved in the sleeve hole to achieve a fixed connection between the second rib 2 and the second connecting portion 5. The connection structure is simple and the installation is easier. Preferably, a latch hole is set on the peripheral side of the sleeve hole, and a fixing hole corresponding to the latch hole is set on the second rib 2. A latch is set in the latch hole, and the latch hole and the fixing hole are inserted by the latch to further fix the connection between the second rib 2 and the second mounting portion, thereby improving the structural stability of the folding rib.

[0034] In this embodiment, strength enhancement holes 6 are further opened on the rib connector 3. The holes make the rib connector 3 have an overall mouth-shaped beam structure, thereby enhancing the bending resistance of the rib connection and improving the overall stability and wind resistance of the folding umbrella ribs.

[0035] As a preferred solution, the first connection part 4 and the second connection part 5 on the rib connection member 3 are staggered in the left-right direction, so that when the folding rib is in the folded state, the first rib 1 and the second rib 2 are staggered with each other and will not be folded on the same vertical plane, so that the first rib 1 can be completely turned over and folded, improving the folding effect and reducing the volume after folding. Of course, in other implementations, the first connection part 4 and the second connection part 5 are staggered in the up-down direction, which can also enable the first rib 1 to be completely turned over and folded, improving the folding effect.

[0036] In this embodiment, a third rib 7 is further provided at the end of the second rib 2 away from the rib connector 3. The third rib 7 is rotatably connected to the second rib 2 and can be flipped and folded to the side of the rib connector 3 to achieve a good folding effect and reduce the length of the rib after folding. As a preferred solution, the bottom of the rib connector 3 includes: a first area 8 corresponding to the bottom of the first connecting portion 4, and a second area 9 corresponding to the bottom of the second connecting portion 5; the second area 9 is set higher than the first area 8, and a guiding slope 10 is provided on the side of the first area 8 close to the second area 9, so that when one end of the third rib 7 is folded to the bottom of the rib connector 3, the third rib 7 can be guided to the bottom of the higher second area 9 to reduce the thickness of the ribs when they are folded and stored, achieving a good folding effect and making the ribs more neat and orderly when they are folded and stored.

[0037] The above is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
