[0024] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0025] like Figure 1 to Figure 5-3 As shown, the connection structure between the tail bead 1 and the rib 2 of the utility model includes: a limiting member and a restraining member, the limiting member is located in the tail bead 1, the restraining member is located at the end of the rib 2, the end of the rib 2 is inserted into the tail bead 1, and the restraining member and the limiting member are detachably connected.

[0026] The detachable connection includes connection by special-shaped pins, connection by clamping or connection by thread. When the end of the umbrella rib 2 is inserted into the umbrella tail bead 1, the restraining member is connected with the limiting member, and the restraining member and the limiting member are not easy to be separated. Even if the restraining member and the limiting member are separated, they can be quickly reconnected together, which does not affect the normal use of the umbrella and can ensure the safety of the umbrella.

[0027] Embodiment 1

[0028] like Figure 1 As shown, the limiting member and the restraining member are connected by snap-fitting.

[0029] The limiting member is a groove arranged circumferentially on the outer surface of the tail bead 1 , and the bottom of the groove is hot-melted and pressed downward into the tail bead 1 to form a protrusion 13 . The restraining member is a ball head 22 located at the end of the rib 2 , and the ball head 22 cooperates with the protrusion 13 in the tail bead 1 .

[0030] There is a section of rib steel wire 24 between the ball head 22 and the end of the rib 2, the outer diameter of the rib steel wire 24 is smaller than the outer diameter of the rib 2, and the outer diameter of the rib steel wire 24 is smaller than the diameter of the ball head 22. The rib steel wire 24 is formed by a cutting process.

[0031] The one side of the ball head 22 connected to the umbrella rib steel wire 24 is flat, and the other side is spherical. In this way, when the ball head 22 is inserted into the umbrella tail bead 1, it is easier to insert with the spherical surface facing inward. After the ball head 22 passes through the protrusion 13, the flat side of the ball head 22 is engaged with the edge of the protrusion 13, and it is not easy to detach from the protrusion 13.

[0032] During installation, the ball head 22 is inserted into the tail bead 1 and passes through the protruding portion 13 of the tail bead 1, and then the tail bead and the umbrella rib are matched by hot-melt pressing and plasticizing.

[0033] Embodiment 2

[0034] like Figure 1 As shown, the limiting member and the restraining member are connected by snap-fitting.

[0035] The limiting member is a boss 14 circumferentially arranged on the inner surface of the tail bead 1 , which is formed by hot melt extrusion. The restraining member is a ball head 22 located at the end of the rib 2 , which cooperates with the boss 14 inside the tail bead 1 .

[0036] There is a section of rib steel wire 24 between the ball head 22 and the end of the rib 2, the outer diameter of the rib steel wire 24 is smaller than the outer diameter of the rib 2, and the outer diameter of the rib steel wire 24 is smaller than the diameter of the ball head 22. The rib steel wire 24 is formed by a cutting process.

[0037] During installation, the ball head 22 is inserted into the tail bead 1 and passes through the boss 14 in the tail bead 1. The ball head 22 has a flat surface on one side connected to the connecting rod and a spherical surface on the other side, so that when the ball head 22 is inserted into the tail bead 1, it is easier to insert with the spherical surface facing inward. After the ball head 22 passes through the boss 14, the flat surface of the ball head 22 is engaged with the edge of the boss 14 and is not easy to be separated from the boss 14.

[0038] Embodiment 3

[0039] like Figure 3 As shown, the limiting member and the restraining member are connected by snap-fitting.

[0040] The limiting member is a third through hole 12 which penetrates the tail bead 1 in the radial direction, and the restraining member is a ball head 22 located at the end of the rib 2 , which matches with the third through hole 12 .

[0041] There is a section of rib steel wire 24 between the ball head 22 and the rib 2, the outer diameter of the rib steel wire 24 is smaller than the outer diameter of the rib 2, and the outer diameter of the rib steel wire 24 is smaller than the diameter of the ball head 22. The rib steel wire 24 is formed by a cutting process.

[0042] During specific use, the ball head 22 enters the interior of the umbrella tail bead 1 and cooperates with the third through hole 12 in the umbrella tail bead 1. The one side of the ball head 22 connected to the connecting rod is flat, and the other side is spherical. In this way, when the ball head 22 is inserted into the umbrella tail bead 1, it is easier to insert with the spherical surface facing inward. After the ball head 22 enters the third through hole 12, the flat side of the ball head 22 is engaged with the edge of the third through hole 12, and it is not easy to detach from the third through hole 12.

[0043] Embodiment 4

[0044] like Figure 4-1 and Figure 4-2 As shown, the limiting member and the restraining member are connected by threads.

[0045] The limiting member is an internal thread 15 inside the tail bead 1 , and the restraining member is an external thread 23 on the outer surface of the end of the rib 2 , and the external thread 23 matches the internal thread 15 .

[0046] During installation, the rib 2 is inserted into the tail bead 1, and the external thread 23 on the outer surface of the rib 2 matches the internal thread 15 inside the tail bead 1. The threaded connection makes it difficult for the rib 2 and the tail bead 1 to separate.

[0047] Embodiment 5

[0048] like Figure 5-1 to Figure 5-3 As shown, the limiting member and the restraining member are connected by a special-shaped pin.

[0049] The limiting member is a first through hole 11 which radially penetrates the tail bead 1 . The restraining member is a second through hole 21 which radially penetrates the rib 2 . The first through hole 11 and the second through hole 21 are connected by a special-shaped pin 3 .

[0050] The cross section of the second through hole 21 is I-shaped, the inner diameters at both ends of the second through hole 21 are larger than the inner diameter of the middle section, and the inner diameter of the first through hole 11 is larger than the inner diameters at both ends of the second through hole 21 .

[0051] When used specifically, Figure 5-3 As shown, insert the end of the rib 2 into the tail bead 1, align the second through hole 21 with the first through hole 11, and then pass the special-shaped pin 3 through the first through hole 11 and the second through hole 21, and finally clamp the special-shaped pin 3 in the first through hole 11 and the second through hole 21.

[0052] The special-shaped pin may be an R-shaped pin.

[0053] like Figure 5-3 As shown, the upper end of the special-shaped pin 3 is circular, the diameter of the circle is larger than the upper end of the second through hole 21, and the middle is narrowest. The lower end of the special-shaped pin 3 is two support rods, and the middle parts of the two support rods protrude to both sides.

[0054] The shape of the special-shaped pin 3 matches the I-shaped shape of the second through hole 21. Since the second through hole 21 is wide at both ends and narrow in the middle, the middle section of the special-shaped pin 3 is also the narrowest part, so that the special-shaped pin 3 can be well stuck in the first through hole 11 and the second through hole 21.
