[0025] See also Figure 1-4A combined live broadcast screen installation mechanism comprises a support frame 1 and an installation frame 2. The upper end of the installation frame 2 is laterally provided with an installation groove 13 for placing the live broadcast screen. The support frame 1 is clamped at the bottom of the installation frame 2. A fixing rod 3 is fixedly connected to the bottom of the support frame 1, and a threaded rod 4 is movably inserted through the bottom of the fixing rod 3. A base 5 supporting the ground is fixedly connected to the bottom of the threaded rod 4. A slide groove 6 connecting the inner cavity is laterally provided at the upper end of the support frame 1, and two groups of symmetrical sliders 7 are slidingly provided on the inner wall of the slide groove 6. A fixing frame 8 is fixedly connected to the upper end of the slider 7, and a threaded pin 9 is inserted through the thread at the upper end of the fixing frame 8. A clamping block 10 is fixedly connected to the upper end of the threaded pin 9. The docking surface of the clamping block 10 near the bottom is provided with clamping grooves 11 clamped to both sides of the upper end of the live broadcast screen, and a guardrail 12 is laterally connected between adjacent fixing frames 8. Among them, the inner cavity of the installation frame 2 is laterally rotatably connected with a rotating shaft 202, and one end of the rotating shaft 202 is movably penetrated and extended to the outside of the installation frame 2, and the outer end of the rotating shaft 202 is fixedly connected with a handle 203, and the surface of the rotating shaft 202 located in the inner cavity of the installation frame 2 is symmetrically provided with threads in opposite directions, and the rotating shaft 202 is connected with the threads between the two groups of sliders 7 through the threads in opposite directions on the outside, the clamping block 10 is connected to the upper end of the slider 7 through the spring telescopic rod 1001, the clamping block 10 and the threaded pin 9 are rotatably connected through the bearing 1002, and the guardrail 12 is designed as a movable telescopic rod structure arranged laterally.

[0026] Based on the above structural design, when the device is installing and fixing the live broadcast screen, the live broadcast screen is placed in the installation groove 13 at the upper end of the installation frame 2, and is manually supported in advance, and then the handle 203 is rotated to drive the rotating shaft 202 to rotate, and the threads on the outer side of the rotating shaft 202 in opposite directions drive the two sets of sliders 7 to slide relatively along the sliding groove 6 at the upper end of the installation frame 2 to adjust the distance, and then the guardrail 12 between the fixed frame 8 is also movable and telescopic to adjust the length, so that the fixed frame 8 can abut against the outside of the live broadcast screen, and then the upper end of the clamping block 10 is driven by rotating the threaded pin 9 to achieve lifting and lowering under the limited clamping of the spring telescopic rod 1001, and the clamping height of the clamping block 10 is adjusted until the clamping groove 11 at the bottom of the clamping block 10 at the upper end of the fixed frame 8 is clamped at the corner position of the upper end of the live broadcast screen, that is, the fixation of the live broadcast screen on the upper end of the installation frame 2 is completed, and the back of the live broadcast screen is supported and protected in cooperation with the guardrail 12 to ensure the relative stability of the live broadcast screen when in use.

[0027] It should be noted that the contact surfaces of the fixed frame 8, the mounting groove 13, the snap-in groove 11 and the guardrail 12 with the live broadcast screen are all provided with rubber pads, which can increase the anti-slip effect and reduce the wear of the contact surfaces between the two.

[0028] Among them, a latch 101 is movably provided on the front of the support frame 1, and a fixing block 102 is fixedly connected to the outer end of the latch 101, and a latch hole 201 is provided on the front of the installation frame 2 to dock with the inner end of the latch 101. The inner side of the fixing block 102 is connected to the front of the support frame 1 through a spring 103, and the spring 103 is a contraction spring. Based on the above structure, the support frame 1 and the installation frame 2 can be transported separately during transportation through the disassembly and assembly structure design, which is convenient for handling and reasonably adjusts the transportation space occupied by the state. When the device assembles and installs the support frame 1 and the installation frame 2, the fixing block 102 is pulled and the latch 101 is stretched to move outward and the spring 103 is stretched synchronously, and then the support frame 1 is clamped to the bottom of the installation frame 2, and the fixing block 102 is loosened to drive the latch 101 to clamp to the clamp hole 201 of the installation frame 2 under the elastic contraction of the spring 103, so that the two can be portable and quickly installed.

[0029] Among them, a plug-in interface is provided at the bottom of the fixed rod 3, and the threaded rod 4 movably penetrates the plug-in interface, and the bottom of the plug-in interface is rotatably connected to the adjustment sleeve 401, and the adjustment sleeve 401 is threadedly sleeved on the outside of the threaded rod 4. Two groups of limit pins 402 are longitudinally fixedly connected to the inner cavity of the fixed rod 3, and the two groups of limit pins 402 are movably plugged into the upper end of the threaded rod 4. When the device is in use, since the live broadcast large screen needs to be adjusted to a suitable installation height when it is installed, and at the same time, the space occupied by the support frame 1 when it is carried is reduced, and when in use, the adjustment sleeve 401 is rotated and the threaded rod 4 is threadedly driven. Since the upper end of the threaded rod 4 is plugged and limited by the two groups of limit pins 402, the adjustment sleeve 401 will threadably drive the threaded rod 4 to rise and fall along the plug-in interface at the bottom of the fixed rod 3 to adjust the height, thereby adjusting the overall support height.
