[0030] Refer to Figures 1-6, an embodiment provided by the present utility model: a performing arts lifting umbrella device, including an umbrella handle 1, a sliding sleeve 3 is slidably connected to the umbrella handle 1, a ratchet wheel 5 is fixedly connected to the sliding sleeve 3, a pawl 6 is engaged with the ratchet wheel 5, a first spring 7 is fixedly connected to the pawl 6, one end of the first spring 7 is fixedly connected to a fixing ring 8, a rotating column 10 is rotatably connected to the fixing ring 8, the rotating column 10 is rotatably connected to the pawl 6, a slider 9 is fixedly connected to the fixing ring 8, a first chute 4 is provided on the umbrella handle 1, and the slider 9 is slidably connected in the first chute 4. By rotating the grip 2 counterclockwise, the ratchet wheel 5 is driven to rotate. When the ratchet wheel 5 rotates, the first spring 7 provided on the pawl 6 contracts, so that when the grip 2 is rotated, the umbrella surface 25 remains stationary and does not rotate along with it. When rotated clockwise, the umbrella surface 25 will be stuck by the ratchet wheel 5 and the pawl 6 and rotate along with it, so that when the umbrella handle 1 rotates in one direction, the umbrella surface 25 rotates along with it, and when the umbrella handle 1 rotates in the other direction, the umbrella surface 25 does not rotate along with it. By restricting the rotation direction of the umbrella surface 25, the umbrella surface 25 can only be driven to rotate unidirectionally, so that the umbrella surface 25 can smoothly rotate and unfold in a specific direction, adding a dynamic visual effect to the performance, creating a more vivid and attractive stage atmosphere, and enhancing the viewing experience of the audience.
[0031] The sliding sleeve 3 is fixedly connected with a first hinge block 14. The first hinge block 14 is hinged with a first connecting rod 15. The first connecting rod 15 is hinged with a second hinge block 16. The second hinge block 16 is fixedly connected with a second connecting rod 17. The second connecting rod 17 is hinged with a first threaded fixing block 11. A second chute 18 is provided on the second connecting rod 17. A clamping block 24 is slidably connected in the second chute 18. A round hole 23 is provided on the clamping block 24. A pulling block 20 is slidably connected in the round hole 23. The pulling block 20 is slidably connected with a third fixing block 19. The third fixing block 19 is fixedly connected to the second connecting rod 17. The third fixing block 19 is fixedly connected with a second spring 21. One end of the second spring 21 is fixedly connected with a fixing piece 22. The fixing piece 22 is fixedly connected to the pulling block 20. The first threaded fixing block 11 is threadedly connected with a threaded column 12. The threaded column 12 is fixedly connected with a second fixing block 13. The first threaded fixing block 11 is rotatably connected to the umbrella handle 1. The clamping block 24 is fixedly connected with the umbrella surface 25. The threaded column 12 penetrates and is connected to the umbrella surface 25. The pulling block 20 is arranged inside the second spring 21. The umbrella handle 1 is fixedly connected with a grip 2. There are multiple groups of the first hinge block 14, multiple groups of the first connecting rod 15, multiple groups of the second hinge block 16, multiple groups of the second connecting rod 17, and multiple groups of the clamping block 24. By manually pulling the pulling block 20 to make the pulling block 20 slide out of the round hole 23, and then twisting the second fixing block 13 to separate the threaded column 12 from the first threaded fixing block 11, the umbrella surface 25 can be removed. When installing the umbrella surface 25, manually pull the pulling block 20 to compress the second spring 21, and then manually press the clamping block 24 into the second chute 18. Stop pulling the pulling block 20. The pulling block 20 is inserted into the round hole 23 by the resilience of the second spring 21, and the replacement and installation of the umbrella surface 25 can be completed. When the umbrella surface 25 is damaged, traditional performing lifting umbrellas may need to replace the entire performance umbrella, which undoubtedly increases the maintenance cost. The design of the umbrella surface 25 that can be quickly replaced only requires replacing the damaged part of the umbrella surface 25, greatly reducing the maintenance cost.
[0032] Working principle: First, when performing the lifting and lowering umbrella show, hold the grip 2 with one hand and the sliding sleeve 3 with the other hand. Push the hand holding the sliding sleeve 3 upwards, so that the sliding sleeve 3 drives the first hinge block 14 to move upwards. The upward movement of the first hinge block 14 drives the first connecting rod 15 to unfold, and the first connecting rod 15 drives the second hinge block 16 to move upwards, thereby driving the second connecting rod 17 to drive the umbrella surface 25 to open. Then, rotate the hand holding the grip 2 counterclockwise, thereby driving the ratchet wheel 5 to rotate. The rotation of the ratchet wheel 5 causes the first spring 7 provided on the pawl 6 to contract, so that when the grip 2 is rotated, the umbrella surface 25 remains stationary and does not rotate along with it. If it is rotated clockwise, the umbrella surface 25 will be stuck by the ratchet wheel 5 and the pawl 6 and rotate along with it, so that when the umbrella handle 1 rotates in one direction, the umbrella surface 25 rotates along with it, and when the umbrella handle 1 rotates in the other direction, the umbrella surface 25 does not rotate along with it. By restricting the rotation direction of the umbrella surface 25, the umbrella surface 25 can only be driven to rotate in one direction, so that the umbrella surface 25 can smoothly rotate and unfold in a specific direction, adding a dynamic visual effect to the performance, creating a more vivid and attractive stage atmosphere, and enhancing the viewing experience of the audience. Then, if the umbrella surface 25 needs to be replaced, manually pull the pulling block 20 to make the pulling block 20 slide out of the circular hole 23, and then twist the second fixing block 13 to separate the threaded column 12 from the first threaded fixing block 11, and the umbrella surface 25 can be removed. When installing the umbrella surface 25, manually pull the pulling block 20 to compress the second spring 21, and then manually press the clamping block 24 into the second chute 18. Stop pulling the pulling block 20, and the pulling block 20 is inserted into the circular hole 23 by the resilience of the second spring 21, and the replacement and installation of the umbrella surface 25 can be completed. If the umbrella surface 25 is damaged, the traditional performing lifting and lowering umbrella may need to replace the entire performance umbrella, which undoubtedly increases the maintenance cost. The design of the umbrella surface 25 that can be quickly replaced only requires replacing the damaged part of the umbrella surface 25, greatly reducing the maintenance cost.
