[0019] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.
[0020] refer to Figure 1-4 The embodiment of the present invention discloses: a carbon fiber umbrella that is easy to open and close, comprising an umbrella body 1 made of carbon fiber umbrella ribs, a middle rod 2 arranged on the umbrella body 1, and an umbrella handle 5 arranged at the bottom end of the middle rod 2, an upper umbrella nest and a lower umbrella nest 4 are arranged between the umbrella body 1 and the middle rod 2, the lower umbrella nest 4 is slidably arranged on the middle rod 2, a first channel 8 is opened in the umbrella handle 5, a rotating rod 10 is rotatably arranged in the first channel 8, a pull rope 6 is wound around the rotating rod 10, a guide wheel 9 is arranged below the middle rod 2 in the first channel 8, the pull rope 6 bypasses the guide wheel 9 and upwardly penetrates into the middle rod 2, a sliding channel is opened on the side of the middle rod 2, a connecting rod (not shown in the figure) is arranged at the bottom of the lower umbrella nest 4 and the connecting rod is slidably arranged in the sliding channel, the other end of the pull rope 6 is arranged on the connecting rod, a coil spring 11 that prevents the connecting rod from pulling the pull rope 6 is arranged in the first channel 8, and the coil spring 11 is arranged in the first channel 8, and the coil spring 11 is connected to the rotating rod 10 and linked to the rotating rod 10.
[0021] In order to further buffer so that the lower umbrella nest 4 does not hit the upper umbrella nest with force, it also includes an eccentric cam 13, the umbrella handle 5 is provided with a rotation channel 12, the end of the rotating rod 10 is located in the rotation channel 12, the eccentric cam 13 is arranged at the end of the rotating rod 10, the umbrella handle 5 is provided with a top ball 14 that abuts against the eccentric cam 13, the umbrella handle 5 is provided with four piston channels 20, the top ball 14 is slidably arranged in the piston channel 20, the top ball 14 is provided with a piston rod 16, the piston rod 16 is provided with a piston plate 15, the piston channel 20 is provided with a second damping device that hinders the sliding of the piston plate 15, the piston channel 20 is provided with a return spring 17 for returning the piston plate 15, the return spring 17 is sleeved on the piston rod 16, one end of the return spring 17 is connected to the inner wall of the piston channel 20, and the other end resists the top ball 14.
[0022] Preferably, the second damping device includes a rotating shaft, which is rotatably arranged in the umbrella handle 5 and located at the piston channel 20. The rotating shaft is respectively provided with a sealing plate 18 that seals the piston channel 20. The piston channel 20 is also provided with a return torsion spring 19 that allows the sealing plate 18 to rotate and reset.
[0023] In order to further improve the buffering effect, a sliding block 7 is slidably provided inside the middle rod 2. The sliding block 7 is fixedly connected to the pull rope 6 and the pull rope 6 passes through the sliding block 7. A friction layer is provided on the sliding block 7. The side of the sliding block 7 resists the inner wall of the middle rod 2.
[0024] Working principle: When in use, when the umbrella is opened, the lower umbrella nest 4 slides upward, pulling the sliding block 7 to slide, and the sliding block 7 rubs against the inner wall of the middle rod 2 when sliding, thereby reducing the impact force of the lower umbrella nest 4 returning to its original position. At the same time, the rotating rod 10 is pulled and rotated, and the rotating rod 10 pulls the coil spring 11, thereby further reducing the impact force of the lower umbrella nest 4. When the rotating rod 10 rotates, it drives the eccentric wheel to rotate and hit the top ball 14, pushing the top ball 14 to compress the return spring 17, and at the same time, the top ball 14 drives the piston rod 16 to slide, and then drives the piston plate 15 to slide, so that the piston plate 15 compresses the gas in the piston channel 20 and pushes the rotation of the sealing plate 18, and the sealing plate 18 compresses the return torsion spring 19, so that the eccentric cam 13 needs to consume more energy when pushing the top ball 14, thereby reducing the force of the lower umbrella nest 4 hitting the upper umbrella nest, so that when the umbrella is opened, the lower umbrella nest 4 will not hit the upper umbrella nest with force, so that the lower umbrella nest 4 and the upper umbrella nest are not easily damaged, and the service life is improved.
