[0044] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0045] Figure 1A structural schematic diagram of an embodiment of the utility model is shown, which relates to an umbrella rib and an umbrella. The main support bone component and the unfolding bone component of the umbrella rib are set off-axis, and the folding bone component and the main support bone component are set coaxially. When the umbrella is folded, along the radial direction of the umbrella, the unfolding bone component and the folding bone component are not in the same radial direction, thereby reducing the volume of the umbrella after folding, making the umbrella easy to carry and store.

[0046] An umbrella rib, such as Figure 1-4 The umbrella ribs are folded and arranged in a folding manner so that the folding bone components 3 and the expansion bone components 2 can be folded together at the opposite sides of the main support bone component 1 to realize the folding and folding of the umbrella ribs. The expansion bone component 2 and the main support bone component 1 are arranged off-axis, and the folding bone component 3 and the main support bone component 1 are arranged coaxially. When the expansion bone component 2 and the folding bone component 3 are folded together, they are not located in the same plane. The expansion bone component 2 and the folding bone component 3 are arranged coaxially with each other. Figure 1 In the AB direction of the umbrella, the folding bone assembly 3 and the unfolding bone assembly 2 are staggered with each other. In the radial direction of the middle rod assembly 5, the folding bone assembly 3 and the unfolding bone assembly 2 partially overlap, so that after the ribs are folded, the overall volume of the umbrella is reduced. The folding bone assembly 3 is connected to the middle rod assembly 5 of the umbrella to realize the installation of the ribs on the middle rod assembly 5 of the umbrella. The arrangement of the unfolding bone assembly 2 and the coccyx assembly 4 controls the opening area of ​​the umbrella and supports the umbrella cloth at the same time.

[0047] When the umbrella ribs are in use, they are installed on the middle rod assembly 5 of the umbrella, driving the folding bone assembly 3 to move, so that the main support bone assembly 1 rotates relative to the folding bone assembly 3, and the main support bone assembly 1 approaches the middle rod assembly 5. The rotation of the main support bone assembly 1 drives the expansion bone assembly 2 to rotate, so that the expansion bone assembly 2 approaches the middle rod assembly 5. The main support bone assembly 1 and the expansion bone assembly 2 rotate in opposite directions. The folding bone assembly 3 and the expansion bone assembly 2 are folded together on both sides of the main support bone assembly 1. Since the expansion bone assembly 2 and the main support bone assembly 1 are eccentrically arranged, the expansion bone assembly 2 and the folding bone assembly 3 are folded together on the main support bone assembly 1 along different radial directions of the middle rod assembly 5. The expansion bone assembly 2 and the folding bone assembly 3 are arranged on different planes, which reduces the size of the expansion bone assembly 2 and the folding bone assembly in the radial direction of the middle rod assembly 5, and reduces the space occupied by the ribs after folding. The rotation of the expansion bone assembly 2 drives the coccyx assembly 4 to rotate, so that the coccyx approaches the middle rod assembly 5, thereby realizing the folding of the umbrella ribs. The overall volume of the umbrella is small after folding, which is convenient for storage and carrying.

[0048] Specifically, such as Figure 1-6 As shown, the above-mentioned main support bone assembly 1 is the main structure of the umbrella rib, and the main support bone assembly 1 includes a main support rod 10 and a first connecting line 11 provided on the main support rod 10, the first connecting line 11 is connected to the folding bone assembly 3 and the unfolding bone assembly 2 respectively, and the setting of the first connecting line 11 controls the rotation of the folding bone assembly 3 and the unfolding bone assembly 2. Through the rotation of the folding bone assembly 3, the main support rod 10 and the unfolding bone assembly 2 are driven to rotate in a predetermined rotation direction for folding. A first accommodating groove 100 and a second accommodating groove 104 are respectively provided on the opposite sides of the main support rod 10. When the folding bone assembly 3 is folded, it can be located in the first accommodating groove 100, and the first accommodating groove 100 accommodates the folding bone assembly 3. When the unfolding bone assembly 2 is folded, it can be located in the second accommodating groove 104, and the second accommodating groove 104 accommodates the unfolding bone assembly 2. The first accommodating groove 100 and the second accommodating groove 104 are eccentrically arranged so that the folding bone assembly 3 and the unfolding bone assembly 2 are arranged on different planes when the umbrella rib is folded, thereby reducing the volume of the umbrella rib when folded.

[0049] like Figure 5 and 6 As shown, the main support rod 10 is a rod-shaped structure with a certain length. The length is selected according to the actual design requirements and no specific requirements are made here. The cross-sectional shape of the main support rod 10 can be circular, square, or other polygonal. The cross-sectional shape of the main support rod 10 is selected according to the actual requirements and no specific requirements are made here. In some feasible embodiments, the cross-sectional shape of the main support rod 10 is preferably rectangular or square, so as to facilitate the provision of the first receiving groove 100 and the second receiving groove 104 on a set of oppositely arranged side surfaces of the main support rod 10.

[0050] The first receiving groove 100 is a groove structure formed by an inward depression on one side of the main support rod 10. The first receiving groove 100 is arranged along the length direction of the main support rod 10 and has a certain length. The length is selected and set according to the length of the foldable bone component 3. Connecting structures are provided at both ends of the main support rod 10 so that the two ends of the main support rod 10 are respectively connected to the foldable bone component 3 and the unfolded bone component 2. The length of the first receiving groove 100 is adapted to the length of the foldable bone component 3 so that the first receiving groove 100 can hold the foldable bone component 3. The foldable bone component 3 will not contact the side of the main support rod 10 where the first receiving groove 100 is provided, thereby preventing the foldable bone component 3 from interfering with the side of the main support rod 10 where the first receiving groove 100 is provided when the foldable bone component 3 is folded. The depth of the first receiving groove 100 is less than the thickness of the main support rod 10, so that the second receiving groove 104 is located on the other side of the main support rod 10. The depth of the first receiving groove 100 can be less than the thickness of the folding bone assembly 3, so that the folding bone assembly 3 partially protrudes from the first receiving groove 100 when it is located in the first receiving groove 100. The arrangement of the first receiving groove 100 allows the folding bone assembly 3 to be close to the main support rod 10 when it is folded, and the folding bone assembly 3 is partially located inside the main support rod 10, reducing the distance between the main support rod 10 and the folding bone assembly 3 in the radial direction of the middle rod assembly 5 (that is, the radial direction of the umbrella), thereby reducing the volume occupied by the umbrella ribs when folded. The first receiving groove 100 is coaxial with the main support rod 10, that is, the axis of the first receiving groove 100 is parallel to the axis of the main support rod 10, and the axis of the first receiving groove 100 coincides with the axis of the main support rod 10, and the two are coaxial. Therefore, the folding bone assembly 3 is also coaxial with the main support rod 10.

[0051] The above-mentioned second accommodating groove 104 is provided on the other side of the main support rod 10. The second accommodating groove 104 is a groove structure, which is formed by the inward depression of this side of the main support rod 10. The length of the second accommodating groove 104 is adapted to the length of the expansion bone component 2, so that when the expansion bone component 2 is folded into the second accommodating groove 104, the expansion bone component 2 will not contact the side of the main support rod 10 where the second accommodating groove 104 is provided, avoiding interference. It also makes the expansion bone component 2 located in the second accommodating groove 104 when folded. Along the radial direction of the middle rod assembly 5, the expansion bone component 2 and the main support rod 10 partially overlap, reducing the size of the expansion bone component 2 and the main support rod 10 in the radial direction of the middle rod assembly 5, and then reducing the size of the umbrella ribs along the radial direction of the middle rod assembly 5 when folded, thereby reducing the size of the umbrella in the radial direction of the middle rod assembly 5 and reducing the volume of the umbrella when folded.

[0052] The axis of the second receiving groove 104 is parallel to the axis of the main support rod 10, and the axis of the second receiving groove 104 does not coincide with the axis of the main support rod 10, with a certain distance between the two. That is, the second receiving groove 104 is offset from the main support rod 10, thereby causing the expanded bone assembly 2 to be offset from the main support rod 10. Therefore, along the radial direction of the middle rod assembly 5, the folded bone assembly 3 and the expanded bone assembly 2 are not in the same plane, allowing the folded bone assembly 3 and the expanded bone assembly 2 to extend into the main support rod 10 in opposite directions, thereby reducing the distance between the folded bone assembly 3 and the expanded bone assembly 2 along the radial direction of the middle rod assembly 5. The cross-sectional shape of the second receiving groove 104 is L-shaped. The second receiving groove 104 is formed by one side of the side surface of the main support rod 10 being recessed toward the other side and toward the direction where the first receiving groove 100 is provided, so as to facilitate the storage of the expanded bone assembly 2 within the second receiving groove 104.

[0053] The first receiving groove 100 is also used to hold the first connecting line 11. The first connecting line 11 is installed in the first receiving groove 100. The first connecting line 11 is arranged along the length direction of the first receiving groove 100. In order to prevent the two ends of the first connecting line 11 from detaching from the first receiving groove 100 when subjected to tension, a limiter 101 is provided in the first receiving groove 100. The limiter 101 and the first receiving groove 100 form a hole structure. One end of the first connecting line 11 passes through the hole structure and is arranged in the first receiving groove 100. The limiter 101 blocks the first connecting line 11 and limits the first connecting line 11 in the first receiving groove 100, so that the first connecting line 11 only moves along the length direction of the first receiving groove 100.

[0054] The limiting member 101 is a block structure or a plate structure. The limiting member 101 is fixedly installed at the opening of the first accommodating groove 100. The limiting member 101 and the two side walls and bottom wall of the first accommodating groove 100 form a hole structure. One end of the first connecting line 11 passes through the hole structure and is installed in the first accommodating groove 100. In order to facilitate the limiting member 101 to block and limit the first connecting line 11, the limiting member 101 is located in the middle position in the length direction of the first accommodating groove 100, and the corresponding position on the folding bone component 3 is provided with a groove or a diameter reduction to prevent the limiting member 101 from interfering with the folding bone component when entering the first accommodating groove 100.

[0055] At least two groups of first mounting holes 103 are provided at one end of the main support rod 10 so that the foldable bone component 3 and the second connecting line 23 can be connected to the main support rod 10 respectively. At this end of the main support rod 10, the first accommodating groove 100 passes through the end along the length direction of the main support rod 10, that is, this end of the main support rod 10 is a groove structure, and at least two groups of first mounting holes 103 are provided on the oppositely arranged side walls of this end of the main support rod 10, and rotating shafts are installed in the two groups of first mounting holes 103. The rotating shafts on the group of first mounting holes 103 near the end are connected to the second connecting line 23, and the rotating shafts on the group of first mounting holes 103 away from the end are connected to the folding bone assembly 3. Along the length direction of the main support rod 10, the folding bone assembly 3 and the parts between the two groups of first mounting holes 103 of the main support rod 10 overlap, and the part of the main support rod 10 between the two groups of first mounting holes 103 blocks the rotation of the folding bone assembly 3, so that the folding bone assembly 3 can only rotate toward the first accommodating groove 100 and cannot rotate toward the second accommodating groove 104. The part of the main support rod 10 between the two groups of first mounting holes 103 limits the rotation of the folding bone assembly 3 and supports the folding bone assembly 3 at the same time.

[0056] The width of the other end of the main support rod 10 is narrowed, and a second mounting hole 102 is provided near the end of this end of the main support rod 10. A rotating shaft is provided in the second mounting hole 102, and the rotating shaft is connected to the expanded bone component 2 to achieve the connection between the expanded bone component 2 and the main support rod 10. Along the length direction of the main support rod 10, the end of the expanded bone component 2 extends toward the other end along the length direction of the main support rod 10. There is an overlapping portion between the main support rod 10 and the expanded bone component 2. This end of the main support rod 10 blocks the rotation of the expanded bone component 2, so that the expanded bone component 2 can only rotate in the direction of the second accommodating groove 104 and cannot rotate in the direction of the first accommodating groove 100, thereby limiting the rotation of the expanded bone component 2 and supporting the expanded bone component 2. In addition, the first connecting line 11 is connected to this end of the expanded bone component 2.

[0057] like Figure 1-4As shown in Figures 7-10, the above-mentioned expansion bone assembly 2 includes an expansion support rod 20, a second connecting line 23, and a first connecting member 22 and a second connecting member 21 respectively arranged at both ends of the expansion support rod 20. The expansion support rod 20 is the main structure of the expansion bone assembly 2. The first connecting member 22 is rotatably connected to the main support rod 10. The expansion support rod 20 is connected to the main support rod 10 through the first connecting member 22, and the expansion support rod 20 is coaxially arranged with the second accommodating groove 104 so that the expansion support rod 20 is located in the second accommodating groove 104 when folded. The second connecting member 21 is rotatably connected to the coccyx assembly 4. The expansion support rod 20 is connected to the coccyx assembly 4 through the second connecting member 21. The two ends of the second connecting line 23 are respectively connected to the main support rod 10 and the coccyx assembly 4, and the rotation of the coccyx assembly 4 is driven by the rotation of the main support rod 10.

[0058] The above-mentioned unfolding support rod 20 is a rod structure, and its cross-sectional shape can be circular, square, or other polygonal shapes. It can be selected according to actual needs and no specific requirements are made here.

[0059] The above-mentioned first connecting member 22 includes a first connecting body 220, a rod connecting portion 222 provided at one end of the first connecting body 220, a wire connecting portion 223 provided at the other end of the first connecting body 220, and a rotating connecting portion 221. The first connecting body 220 is a plate-shaped structure. The setting of the first connecting body 220 facilitates the installation of the rod connecting portion 222, the wire connecting portion 223 and the rotating connecting portion 221. The rod connecting portion 222 is provided at one end of the first connecting body 220. The rod connecting portion 222 is a hole structure so that one end of the expansion support rod 20 can be inserted into the rod connecting portion 222. The first connecting member 22 is installed on the expansion support rod 20. When the rod connecting portion 222 is set, the axis of the rod connecting portion 222 is aligned with the first connecting member 220. The axis of a connecting body 220 is set in parallel, and there is a certain distance between the axis of the rod connecting part 222 and the axis of the first connecting body 220, that is, the rod connecting part 222 and the first connecting body 220 are set eccentrically, and the first connecting body 220 and the main support rod 10 are set coaxially, so that the unfolding support rod 20 and the main support rod 10 are set eccentrically, so that when the unfolding support rod 20 is folded on the main support rod 10, the size of the unfolding support rod 20 and the main support rod 10 along the radial direction of the middle rod assembly 5 is reduced, thereby reducing the size of the umbrella ribs along the radial direction when the umbrella ribs are folded, and also making the unfolding support rod 20 and the folding bone assembly 3 eccentrically set along the radial direction of the middle rod assembly 5, and not located in the same plane.

[0060] The rotating connection part 210 is fixedly arranged on the side surface of the first connecting body 220 facing the main support rod 10 so that the rotating connection part 210 is rotatably connected to the main support rod 10. The rotating connection part 210 is a set of relatively arranged lug structures. At this time, the end parts of the main support rod 10 connected to the rotating connection part 210 are a block structure, and the two lug structures are provided with coaxial through holes. The rotating shaft passes through the through hole on one lug structure, the second mounting hole 102 on the main support rod 10 and the through hole of the other lug structure in sequence, connecting the rotating connection part 210 and the main support rod 10 together, and the rotating connection part 210 can rotate relative to the main support rod 10; of course, the rotating connection part 210 can also be a block structure provided with a through hole, and correspondingly, the end parts of the main support rod 10 connected to the rotating connection part 210 are a set of relatively arranged lug structures. The structure of the rotating connection part 210 is adapted to the structure of the end parts of the main support rod 10 and can be selected according to actual needs.

[0061] The wire connection portion 223 is fixedly mounted on the other end of the first connecting body 220. The wire connection portion 223 includes a first and a second protrusion disposed opposite each other. The first and second protrusions are provided with coaxial through-holes. A rotating shaft passes through the through-holes of the first and second protrusions in sequence and is rotatably mounted on the first and second protrusions. A gap is provided between the first and second protrusions so that the first connecting wire 11 is located within the gap and connected to the rotating shaft, thereby connecting the first connecting wire 11 to the first connecting member 22. The side of the first protrusion facing the main support rod 10 is a planar structure. A groove is provided on the main support rod 10 at a position corresponding to the planar structure. The planar structure of the first protrusion is inserted into the groove. The wire connection portion 223 overlaps with a portion of the end of the main support rod 10. When the ribs are in the open state, the main support rod 10 can support the unfolding support rod 20. At the same time, when the umbrella is exposed to upward wind, the end of the main support rod 10 supports and blocks the wire connection portion 223, preventing the umbrella from folding upward.

[0062] The above-mentioned second connecting member 21 is a plate-like structure with a certain thickness. One end of the second connecting member 21 is provided with a first plug hole 210, and the first plug hole 210 is used to connect with the deployment support rod 20. The other end of the deployment support rod 20 away from the first connecting member 22 is inserted into the first plug hole 210, and the second connecting member 21 is installed on the deployment support rod 20; the other end of the second connecting member 21 is provided with a first rotating connection part 211, and the first rotating connection part 211 is a group of relatively arranged lug structures, each lug structure is provided with a through hole, and the through holes on the two lug structures are coaxially arranged, and there is a gap between the two lug structures so that the two lug structures are connected to the coccyx assembly 4 through a rotating shaft, and the rotating shaft is passed through the through holes of the two lug structures. A accommodating groove 212 is provided on one side surface of the second connecting member 21 so that when the coccyx assembly 4 is folded, part of the coccyx assembly 4 can be located in the accommodating groove 212, and the coccyx assembly 4 can extend to the interior of the second connecting member 21, thereby reducing the size of the coccyx assembly 4 and the expanded bone assembly 2 in the radial direction of the middle rod assembly 5.

[0063] like Figure 1-4 As shown in Figure 11, the above-mentioned coccyx assembly 4 includes a coccyx support rod 40 and a fifth connecting member 41 provided at one end of the coccyx support rod 40. The fifth connecting member 41 is rotatably connected to the second connecting member 21. The coccyx support rod 40 is a rod structure. Its cross-sectional shape can be circular, quadrilateral, or other polygons. It can be selected according to actual needs and no specific requirements are made here. The setting of the fifth connecting member 41 connects the coccyx support rod 40 to the unfolding support rod 20. One end of the fifth connecting member 41 is provided with a second plug hole 411. One end of the coccyx support rod 40 is plugged into the second plug hole 411 of the fifth connecting member 41. The fifth connecting member 41 is installed on the coccyx support rod 40. The other end of the fifth connecting member 41 is provided with a first line connection part 412. The first line connection part 412 is a group of relatively arranged lug structures. A rotating shaft is rotatably installed on the group of lug structures. The rotating shaft is connected to the second connecting line 23. A second rotating connection part 410 is provided on a side of the fifth connecting member 41 facing the second connecting member 21, and the second rotating connection part 410 is provided with a mounting hole. The second rotating connection part 410 is located between the two lug structures of the first rotating connection part 211 of the second connecting member 21. The mounting hole of the second rotating connection part 410 is coaxially arranged with the through hole of the first rotating connection part 211. The rotating shaft on the second rotating connection part 410 passes through the through hole on the first rotating connection part 211, so as to realize the rotating connection between the second connecting member 21 and the fifth connecting member 41.

[0064] The fifth connecting member 41 is provided with an abutting portion 413, which is provided on one side of the fifth connecting member 41 facing the second connecting member 21. In this embodiment, the abutting portion 413 is located on a group of lug structures of the second rotating connecting portion 410 of the fifth connecting member 41. The second connecting member 21 is provided with an abutting groove 213, and the abutting portion 413 is provided in the abutting groove 213. The abutting portion 413 can rotate along the abutting groove 213 to limit the reverse rotation of the coccyx support rod 40. An abutting portion 413 is provided on the side of the second connecting member 21 facing the fifth connecting member 41. The contact groove 213 is formed by the inward depression of the side surface of the second connecting member 21, and the bottom of the contact groove 213 is in an arc shape. The shape of the contact portion 413 is adapted to the shape of the contact groove 213, so that when the umbrella rib is in the open state, the contact portion 413 is located in the contact groove 213 and can rotate in the contact groove 213. When the umbrella rib is in the open state, the second connecting member 21 supports the fifth connecting member 41. When the umbrella is subjected to upward wind, the second connecting member 21 blocks the fifth connecting member 41 to prevent the umbrella from folding upward.

[0065] The above-mentioned coccyx support rod 40 can be coaxially arranged with the deployment support rod 20, and the axis of the coccyx support rod 40 is located on the same straight line as the axis of the deployment support rod 20, or the coccyx support rod 40 and the deployment support rod 20 are eccentrically arranged, and the axis of the coccyx support rod 40 is not on the same straight line as the axis of the deployment support rod 20. The arrangement method of the coccyx support rod 40 and the deployment support rod 20 is selected according to actual needs. In this embodiment, the coccyx support rod 40 and the deployment support rod 20 are eccentrically arranged. When the umbrella ribs are folded, the size between the coccyx component 4 and the deployment bone component 2 in the radial direction of the middle rod component 5 is further reduced, thereby reducing the volume of the umbrella ribs.

[0066] A protective cover is provided at the other end of the coccyx support rod 40 to prevent the coccyx support rod 40 from causing damage to people or objects outside when the umbrella is in use.

[0067] like Figure 1-4 As shown, the foldable rib assembly 3 is configured to connect the ribs to the center rod assembly 5. The foldable rib assembly 3 includes a foldable support rod 30, a third connecting member 31 and a fourth connecting member 32 respectively provided at both ends of the foldable support rod 30, a third connecting line 34, and a side support rod 33. One end of the side support rod 33 is rotatably connected to the third connecting member 31, and the other end of the side support rod 33 is rotatably connected to the center rod assembly 5. The ends of the third connecting line 34 are respectively connected to the side support rod 33 and the main support rod 10. The fourth connecting member 32 is rotatably connected to the main support rod 10, and the third connecting member 31 is rotatably connected to the center rod assembly 5. The foldable support rod 30 is a rod structure, and its cross-sectional shape can be circular, square, or other polygonal. The cross-sectional shape of the foldable support rod 30 is selected according to actual needs and is not specifically required here.

[0068] The above-mentioned fourth connecting member 32 is set to connect the folding support rod 30 with the main support rod 10. A third plug hole is set at one end of the fourth connecting member 32, and one end of the folding support rod 30 is plugged into the third plug hole to install the fourth connecting member 32 on the folding support rod 30; a third mounting hole is set at the other end of the fourth connecting member 32, and this end of the fourth connecting member 32 is rotatably connected to the rotating shaft on the first mounting hole 103 on the end of the main support rod 10 through the third mounting hole, so that the fourth connecting member 32 can rotate relative to the main support rod 10, and a second wire connecting part 320 is set on the side surface of the fourth connecting member 32 away from the main support rod 10, and the second wire connecting part 320 is connected to the first connecting line 11, so that the first connecting line 11 and the fourth connecting member 32 are connected together.

[0069] The setting of the above-mentioned third connecting member 31 facilitates the connection of the folding support rod 30 with the middle rod assembly 5 and the side support rod 33 respectively. A fourth plug hole is provided at one end of the third connecting member 31, and the folding support rod 30 is inserted into the fourth plug hole. The third connecting member 31 is installed on the folding support rod 30, and a third rotating connection part is provided on one side surface of the third connecting member 31. The third rotating connection part is a block structure, and the third rotating connection part is provided with a through hole, so that the third rotating connection part is connected to the side support rod 33 through a rotating shaft, and the other end of the third connecting member 31 is rotatably connected to the middle rod assembly 5 through a rotating shaft.

[0070] One end of the side support rod 33 is provided with a set of oppositely arranged lug structures, each of which is provided with a coaxial through-hole. When the side support rod 33 is mounted on the third connecting member 31, the third rotating connection portion on the third connecting member 31 is located between the set of lug structures at that end of the side support rod 33. The through-hole on the third rotating connection portion is coaxial with the through-hole on the lug structure. The rotating shaft is provided on the through-hole of the third rotating connection portion and the through-hole of the lug structure, thereby realizing the rotational connection between the third rotating connection portion and the side support rod 33. The side support rod 33 is provided with a mounting shaft, which can rotate relative to the side support rod 33 and is connected to the third connecting line 34.

[0071] The above-mentioned side support rod 33 is provided with a third accommodating groove 330, which is arranged along the length direction of the side support rod 33 and is formed by an inward depression of one side surface of the side support rod 33. When the folding support rod 30 is folded, it can be located in the third accommodating groove 330, further reducing the folded volume of the umbrella ribs.

[0072] The folding support rod 30, the unfolding support rod 20 and the coccyx support rod 40 are all fiber rods, which reduces the weight of the umbrella ribs.

[0073] The materials of the above-mentioned first connecting member 22, second connecting member 21, third connecting member 31, fourth connecting member 32 and fifth connecting member 41 are all plastic, which has good wear resistance, so that the first connecting member 22, second connecting member 21, third connecting member 31, fourth connecting member 32 and fifth connecting member 41 have a long service life, and are simple to manufacture and easy to prepare.

[0074] The main support rod 10 is made of stainless steel to enhance the strength of the umbrella ribs.

[0075] The above-mentioned first connecting line 11, second connecting line 23 and third connecting line 34 are all steel lines. The setting of the first connecting line 11, the second connecting line 23 and the third connecting line 34 connects the folding support rod 30, the main support rod 10 and the unfolding support rod 20 together, realizing the linkage of the folding support rod 30, the main support rod 10 and the unfolding support rod 20, and realizing the folding and unfolding of the umbrella ribs.

[0076] An umbrella, such as Figure 12 As shown, it includes a middle rod assembly 5 and a plurality of umbrella ribs as described above. The plurality of umbrella ribs are connected to the middle rod assembly 5 and are arranged in sequence along the circumferential direction of the middle rod assembly 5. The middle rod assembly 5 includes a middle rod 50 and an upper nest 52 and a lower nest 51 provided on the middle rod 50. The upper nest 52 is fixedly mounted on one end of the middle rod 50, and the lower nest 51 is slidably provided on the middle rod 50. When the ribs are connected to the middle rod assembly 5, the side support rod 33 of the folding rib assembly 3 is rotatably connected to the upper nest 52, and the folding support rod 30 is rotatably connected to the lower nest 51. By driving the lower nest 51 to move, the simultaneous folding and opening of each rib is achieved.

[0077] When each umbrella rib is folded, the lower nest 51 slides downward along the middle rod 50, and the folding support rod 30 rotates, driving the side support rod 33 to rotate toward the folding support rod 30. With the help of the connection of the third connecting line 34, the folding support rod 30 rotates and drives the main support rod 10 to rotate toward the middle rod 50. The folding support rod 30 and the main support rod 10 are folded and folded, and the main support rod 10 is close to the folding support rod 30. As the main support rod 10 rotates, a part of the folding support rod 30 enters the first receiving groove 100 of the main support rod 10, realizing the folding of the folding support rod 30 and the main support rod 10. Parts of the third connecting member 31, the folding support rod 30 and the fourth connecting member 32 are all located in the first receiving groove 100, and the side support rod 33 and the folding support rod 30 are close to each other and folded, and part of the folding support rod 30 is located in the third receiving groove 330 of the side support rod 33.

[0078] As the main support rod 10 rotates, with the help of the first connecting line 11, the main support rod 10 rotates to drive the rotation of the expansion support rod 20, and the expansion support rod 20 rotates toward the middle rod 50. As the expansion support rod 20 rotates, part of the expansion support rod 20 enters the second receiving groove 104 of the main support rod 10, realizing the folding of the expansion support rod 20, and part of the second connecting member 21 is also located in the second receiving groove 104. Due to the eccentricity of the second receiving groove 104 and the first receiving groove 100, the expansion support rod 20 and the folding support rod 20 are eccentric. The eccentric arrangement of the stacking support rod 30 causes the unfolding support rod 20 and the folding support rod 30 to be arranged in different planes along the radial direction of the middle rod 50. The unfolding support rod 20 and the folding support rod 30 are not located in the same plane, so that both the unfolding support rod 20 and the folding support rod 30 are partially located inside the main support rod 10. Along the radial direction of the middle rod 50, the unfolding support rod 20 and the folding support rod 30 partially overlap, thereby reducing the size of the umbrella ribs along the radial direction of the middle rod 50, making the umbrella smaller in size when folded, and easier to store.

[0079] As the deployment support rod 20 rotates and with the help of the second connecting line 23, the coccyx support rod 40 rotates, the coccyx support rod 40 rotates toward the middle rod 50, and the coccyx support rod 40 rotates toward the deployment support rod 20, and the coccyx support rod 40 is folded to one side of the deployment support rod 20, completing the folding of the umbrella ribs.

[0080] Due to the adoption of the above technical solution, the umbrella ribs have a folding bone component and an expanding bone component, the folding bone component and the expanding bone component are rotatably arranged at both ends of the main support bone component, the folding bone component and the expanding bone component can both rotate relative to the main support bone component, and the rotation directions of the folding bone component and the expanding bone component are opposite, so that the folding bone component and the expanding bone component are folded at both sides of the main support bone component, the folding bone component and the expanding bone component are arranged on different planes along the radial direction of the middle rod of the umbrella, the folding bone component and the main support bone component are coaxially arranged, and the expanding bone component and the main support bone component are eccentrically arranged, so that when the folding bone component and the expanding bone component are folded, at least part of them are respectively folded into the first receiving groove and the second receiving groove of the main support rod. The folding frame assembly has a third receiving groove, and the side support rod of the folding frame assembly is folded into the third receiving groove, which further reduces the size of the umbrella ribs along the radial direction of the middle rod and the volume of the folded umbrella. The second connecting member and the fifth connecting member cooperate with the abutting groove and the abutting portion, so that the second connecting member supports the fifth connecting member and blocks the rotation of the fifth connecting member at the same time, preventing the umbrella from folding upward when subjected to upward wind, thereby enhancing the wind resistance and strength of the umbrella.

However, the above contents are only preferred embodiments of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
