Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1 and Figure 2The utility model provides an embodiment: a portable film and television stage quick installation structure, including a stage board 1, a rectangular array of support rods 2 are fixedly connected to the top of the stage board 1, a bracket 3 is fixedly connected inside the support rod 2, a rotating shaft 6 is rotatably connected inside the bracket 3, one end of the rotating shaft 6 is fixedly connected to a handle 11, a plurality of positive and negative threads 7 are provided on the outer wall of the rotating shaft 6, a plurality of groups of movable plates 8 are arranged on the outer wall of the rotating shaft 6, the inner threads of the movable plates 8 are connected to the outer wall of the positive and negative threads 7, the outer wall of the movable plates 8 is rotatably connected to a ring array of transmission rods 9, a card block 10 is rotatably connected to one side of the transmission rod 9, the card block 10 is slidably connected to the inside of the bracket 3, a mounting ring 5 is arranged on the outer wall of the bracket 3, the bracket 3 is slidably connected to the inside of the mounting ring 5, and a stage light 4 is fixedly connected to the bottom of the mounting ring 5;

[0024] Specifically, first, align the mounting ring 5 at the bottom of the stage light 4 with the bracket 3, and then put it on the bracket 3. Next, operate the handle 11 to drive the rotating shaft 6 to rotate, and the positive and negative threads 7 of the rotating shaft 6 will move accordingly, thereby driving the movable plates 8 symmetrical on both sides to move relative to each other. When the movable plates 8 are driven by the rotating shaft 6, the transmission rod 9 will transmit the force to the block 10. Under the action of the transmission rod 9, the block 10 can smoothly slide out from the inside of the bracket 3, ensuring that the mounting ring 5 is firmly fixed on the bracket 3.

[0025] Reference Figure 1 and Figure 3 The outer wall of the bracket 3 is provided with a mounting assembly, the mounting assembly includes a mounting hole 12 and a mounting hole 2 13, the mounting hole 12 is opened on the outer wall of the bracket 3, and the mounting hole 2 13 is opened inside the support rod 2;

[0026] Specifically, a second mounting hole 13 is provided on the support rod 2 , corresponding to a first mounting hole 12 provided on the outer wall of the bracket 3 , thereby facilitating the installation of the bracket 3 on the support rod 2 and facilitating quick installation between the support rod 2 and the bracket 3 .

[0027] Reference Figure 3 and Figure 4 The stage board 1 has a threaded column 15 connected to the inner part thereof, a circular array of card slots 20 is provided inside the support rod 2, one end of the threaded column 15 is fixedly connected to a handle 14, a slide rod 18 is fixedly connected inside the stage board 1, the other end of the threaded column 15 is rotatably connected to a push block 16, a circular array of rotating rods 17 are rotatably connected inside the push block 16, the outer wall of the slide rod 18 is slidably connected to the circular array of card slots 20, one side of the rotating rod 17 is rotatably connected to the inner side of the slider 19, and one side of the outer wall of the card slot 20 is slidably connected to the inner part of the card slot 20;

[0028] Specifically, first, the threaded column 15 is driven to rotate by the handle 14. This rotation process transmits force to the push block 16, which in turn causes the push block 16 to move. When the threaded column 15 pushes the push block 16 to move, the rotating rod 17 will also rotate accordingly. The rotating rod 17 is connected to the slider 19, so that the slider 19 slides outward on the slider 18. When the slider 19 slides into the groove 20 at the bottom of the support rod 2, the support rod 2 is firmly fixed on the stage board 1.

[0029] Working principle: When the stage light 4 is installed, the mounting ring 5 at the bottom of the stage light 4 can be sleeved on the bracket 3, and then the handle 11 is used to drive the rotating shaft 6 to rotate, and the positive and negative threads 7 of the rotating shaft 6 will drive the two symmetrical movable plates 8 to make relative movements, so that the movable plate 8 drives the card block 10 through the transmission rod 9, so that the card block 10 slides out of the bracket 3, thereby fixing the mounting ring 5 on the bracket 3, and then the mounting hole 12 cooperates with the mounting hole 2 13 to fix the bracket 3 on the top of the support rod 2. When the support rod 2 is installed on the stage board 1, the handle 14 can be used to drive the threaded column 15 to rotate, and the threaded column 15 can push the push block 16 to move, and then the rotating rod 17 inside the push block 16 drives the slider 19 to slide outward on the slide rod 18, so that the slider 19 slides into the card groove 20 at the bottom of the support rod 2, so that the support rod 2 is fixed on the stage board 1.
