[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-6 As shown, the immersive panoramic projection support structure includes a mounting rod 1, an adjusting rod 2 slidably connected to the mounting rod 1, a mounting block 3 rotatably connected to the adjusting rod 2, a mounting structure 4 on the mounting block 3, and a mounting column 401. A connecting column 402 is detachably connected to the mounting column 401, and a threaded rod 403 is fixedly connected to the connecting column 402. A projector 6 is threadedly connected to the threaded rod 403. Two limiting blocks 404 are slidably connected inside the mounting column 401. The connecting column 402 has multiple limiting holes 405, and the two limiting blocks 404 respectively engage with two of the limiting holes 405. The limiting blocks 404 have inclined surfaces, and a connecting plate 406 is fixedly connected to the limiting blocks 404. A first spring 408 is fixedly connected between the connecting plate 406 and the mounting column 401.

[0025] As a technical optimization of this utility model, the bottom of the cross-section of the mounting column 401 is trapezoidal, the limiting holes 405 are distributed in a circular array about the center of the mounting column 401, a guide rod 407 is fixedly connected inside the mounting column 401, the connecting plate 406 is slidably connected to the guide rod 407, and the connecting plate 406 slides with the guide rod 407. The setting of the guide rod 407 makes the sliding of the connecting plate 406 more stable.

[0026] As a technical optimization of this utility model, a rotating shaft 7 is rotatably connected to the adjusting rod 2, and the mounting block 3 is fixedly connected to the rotating shaft 7. A first knob 8 is threadedly connected to the rotating shaft 7. The first knob 8 abuts against the adjusting rod 2. When the mounting block 3 adjusts its angle through the rotating shaft 7, the first knob 8 can be rotated to make it abut against the adjusting rod 2, thereby fixing the rotated mounting block 3 and improving its stability. A second knob 9 is threadedly connected to the mounting rod 1. The second knob 9 abuts against the adjusting rod 2. At the same time, after the adjusting rod 2 slides against the mounting rod 1, the second knob 9 can be rotated to make it abut against the adjusting rod 2, thereby fixing the slid adjusting rod 2 and improving its stability.

[0027] As a technical optimization of this utility model, the mounting rod 1 is provided with a hidden structure 5, which includes a hidden box 501. The hidden box 501 is slidably connected to the mounting rod 1, and then the hidden box 501 slides to cover the transformer, thus completing the concealment of the transformer and facilitating the storage of the transformer and its cables, improving the aesthetics of the wall. A sliding sleeve 502 is fixedly connected to the hidden box 501, and a limiting rod 503 is slidably connected to the sliding sleeve 502. The mounting rod 1 is provided with two limiting grooves 504, and the limiting rod 503 is connected to one of the limiting grooves 504. 04. Engagement: The limiting rod 503 engages with the limiting groove 504 to secure the slidable hidden box 501. A pressing rod 505 is fixedly connected to the limiting rod 503. A screw hole 507 is provided on the sliding sleeve 502, and a screw 506 is threaded into the screw hole 507. The pressing rod 505 and the screw 506 are slidably connected. A second spring 508 abuts between the pressing rod 505 and the screw 506. When replacing the second spring 508, simply unscrew the screw 506 from the screw hole 507 to replace the second spring 508. A placement groove 10 is provided on the mounting rod 1.

[0028] In use, when the projector 6 is installed, the threaded rod 403 on the connecting post 402 is first threadedly engaged with the threaded hole of the projector 6's pan-tilt head. Then, the entire bracket is installed on the wall. After installation, when installing the projector 6, the connecting post 402 is inserted into the mounting post 401. Because the bottom of the mounting post 401 has a trapezoidal cross-section, it provides guidance, facilitating quick and easy docking of the two components, making installation more convenient. Simultaneously, when the inclined surface of the limiting block 404 abuts against the connecting post 402, it retracts into the mounting post 401. At the same time, the limiting block 404 causes the connecting plate 406 to slide, which in turn causes the first spring 408 to retract. The connecting plate 406 slides with the guide rod 407. The guide rod 407 makes the sliding of the connecting plate 406 more stable. When the connecting post 402 and the mounting post 401 are fully inserted, the limiting block 404 will engage with the limiting hole 405 under the action of the first spring 408. At this time, the installation is completed. When disassembling, simply press the two connecting plates 406 to drive the limiting block 404 to slide until it is no longer engaged with the limiting hole 405. The engagement of the two limiting blocks 404 with the mounting post 401 allows for quick disassembly and assembly between the mounting post 401 and the connecting post 402, thereby improving the efficiency and convenience of disassembly and assembly of the projector 6. When the mounting block 3 is adjusted in angle by the rotating shaft 7, the first rotating shaft can be rotated to adjust the angle. Knob 8 is turned so that the first knob 8 abuts against the adjusting rod 2, fixing the rotating mounting block 3 and improving its stability. Simultaneously, after the adjusting rod 2 slides against the mounting rod 1, the second knob 9 is turned so that it abuts against the adjusting rod 2, fixing the sliding adjusting rod 2 and improving its stability. When it is necessary to hide the transformer of the projector 6, first press the pressing rod 505. As the pressing rod 505 moves downward, it slides against the screw 506. The screw 506 makes the sliding of the pressing rod 505 more stable. At the same time, the second spring 508 retracts, and the pressing rod 505 will cause the limiting rod 503 to no longer engage with the limiting groove 504. At this time, the hiding box 501 can be slid on the mounting rod 1. Set a fixed distance, then release the pressing rod 505, causing the limiting rod 503 to engage with another limiting groove 504 under the action of the second spring 508. The engagement of the limiting rod 503 with the limiting groove 504 facilitates the fixation of the slid-out hidden box 501. At this time, the hidden box 501 no longer obstructs the placement groove 10. The transformer of the projector 6 can be placed in the placement groove 10, and then the hidden box 501 can be slid to cover the transformer, thus completing the concealment of the transformer. This also facilitates the storage of the transformer and its cables, improving the aesthetics of the wall. When replacing the second spring 508, simply unscrew the screw 506 from the screw hole 507, and then replace the second spring 508.
