DETAILED DESCRIPTION

[0020] In order to make the above features and advantages of the present invention more obvious and understandable, embodiments are given below with reference to the accompanying drawings for detailed description as follows.

[0021] like Figure 1-Figure 4 As shown, this embodiment provides a deformation-resistant carbon fiber umbrella, including an umbrella center rod 1, umbrella ribs 2 and a push seat 3.

[0022] The push seat 3 is sleeved on the umbrella rod 1 for sliding. The push seat 3 includes an upper seat body 31, a spring 32 and a lower seat body 33. The upper seat body 31, the spring 32 and the lower seat body 33 are arranged in sequence from top to bottom, and the two ends of the spring 32 are fixedly connected to the upper seat body 31 and the lower seat body 33 respectively.

[0023] The ribs 2 include a first umbrella bar 21 and a second umbrella bar 22. The first umbrella bar 21 includes a metal bar 211 and a carbon fiber bar 212. The metal bar 211 is made of existing commonly used stainless steel or iron. The metal bar 211 is located on the side close to the umbrella center rod 1. The carbon fiber bar 212 is detachably connected to the end of the metal bar 211. Specifically, the end face of the metal bar 211 has a slot 2111, and the surface of the metal bar 211 has a first through hole, and the first through hole passes through the slot 2111. One end face of the carbon fiber bar 212 has an insert plate 2123, and the surface of the insert plate 2123 has a second through hole. The insert plate 2123 is adapted to the slot 2111. The metal bar 211 and the carbon fiber bar 212 are connected by rivets passing through the first through hole and the second through hole.

[0024] The metal strip 211 includes a horizontal strip 2112 and two vertical strips 2113. The two vertical strips 2113 are connected on both sides of the horizontal strip 2112. The end faces of the two vertical strips 2113 located on one side of the end of the horizontal strip 2112 fit together to form a slot 2111. The other ends of the two vertical strips 2113 have an extension strip 2115, and the extension strip 2115 is provided with a first hinge hole.

[0025] The carbon fiber strip 212 includes a first connecting portion 2121 and a first tip portion 2122. The vertical cross-section of the first connecting portion 2121 is a rectangle with a narrow upper portion and a wide side. The first connecting portion 2121 with a vertical cross-section is a rectangle with a narrow upper portion and a wide side, and has a stronger deformation resistance. The first tip portion 2122 is connected to the outward side of the first connecting portion 2121, and the area of ​​the vertical cross-section projection of the first tip portion 2122 gradually decreases from the inside to the outside. The first tip portion 2122 is used to cover the tip of the rib 2 at the end of the umbrella surface.

[0026] One end of the first umbrella strip 21 is hinged to the upper end of the umbrella middle rod 1, and one end of the second umbrella strip 22 is hinged to the pushing seat 3. Specifically, a first annular platform is formed on the circumferential surface below the upper seat body 31, and a first hinge notch is formed on the circumferential surface of the first annular platform. A first hinge rod is provided in the first hinge notch, and the end of the second umbrella strip 22 extends into the first hinge notch and is hinged through the first hinge rod.

[0027] The other end of the second umbrella strip 22 is hinged to the first umbrella strip 21. Specifically, the end of the second umbrella strip 22 extends between the two convex plates 2114 and is hinged to the second hinge hole. A third umbrella strip 23 is arranged between the lower seat 33 and the second umbrella strip. One end of the third umbrella strip 23 is hinged to the second umbrella strip, and the other end of the third umbrella strip 23 is hinged to the lower seat 33. Specifically, a second annular platform is formed on the upper circumference of the lower seat 33, and a second hinge notch is formed on the circumference of the second annular platform. A second hinge rod is provided in the second hinge notch. The end of the third umbrella strip 23 extends into the second hinge notch and is hinged through the second hinge rod.

[0028] The carbon fiber umbrella of the present scheme forms a stable triangular support structure through the metal strip 211, the second strip 22 and the umbrella middle rod 1, so that the first strip 21 not made of carbon fiber material has a strong anti-deformation ability, and the carbon fiber strip 212 made of carbon fiber material is used at the end of the first strip 21 that is not supported (that is, the carbon fiber strip 212 part), and the carbon fiber strip 212 itself has excellent anti-deformation ability, so that the entire first strip 21 has strong anti-deformation ability, and in order to further improve the strength of the carbon fiber umbrella, a third strip 23 is also provided between the second strip 22 and the lower seat 33, which is used to further improve the anti-deformation ability of the carbon fiber umbrella. Compared with the umbrella made of carbon fiber material for the entire first strip 21, the carbon fiber umbrella provided in the present scheme is more economical.

[0029] The above shows and describes the basic principles and main features of the invention and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the invention, the utility model may have various changes and improvements, which shall fall within the scope of the utility model to be protected.
