[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick installation and calibration auxiliary tool for movie projection equipment, comprising: a mounting frame, and a projector body mounted on the upper side of the mounting frame, wherein a connecting plate is connected to the outer side of the projector body;

[0007] Also includes:

[0008] A limiting block is installed on the outside of the mounting frame, and a guide rod is connected to the outside of the limiting block. An operating rod is connected to the middle of the connecting plate, and a damper is nested in the middle of the operating rod. A pointer is provided at the front end of the mounting frame.

[0009] A support frame is installed on the lower side of the mounting frame, and a support column is provided on the outer side of the support frame.

[0018] Compared with the prior art, the beneficial effects of this utility model are: this quick installation and calibration auxiliary tool for movie projection equipment facilitates rapid disassembly and replacement of the projection equipment after use, making it easy for users to conveniently replace and recycle the projection equipment, avoiding any impact on the efficiency of disassembly and maintenance. Simultaneously, an effective scale observation structure is set inside the device, allowing users to effectively observe the offset angle during the calibration process of the projection equipment, resulting in a better user experience, as detailed below:

[0019] The damper, in conjunction with the guide rod, pushes the limiting block connected to its inner side to move inward, so that the limiting block moving inward engages with the connecting plate to fix the projector body.

[0028] 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.

[0029] Please see Figure 1-5This utility model provides a technical solution: a quick installation and calibration auxiliary tool for movie projection equipment, including a base 1, an anti-slip pad 2, a first drive motor 3, a drive rod 4, a support column 5, a first guide block 6, a second drive motor 7, a first drive disk 8, a support frame 9, a second drive disk 10, a rotation damper 11, a mounting frame 12, a second guide block 13, a scale 14, a pointer 15, a projector body 16, a connecting plate 17, a limit block 18, a guide rod 19, an operating lever 20, and a damper 21.

[0030] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, by pulling the operating lever 20 on the outer side of the mounting bracket 12 outward, the operating lever 20 causes the limiting block 18 connected to its inner side to move outward. At this time, due to the sliding connection between the limiting block 18 and the guide rod 19, the limiting block 18 moving outward is guided and limited by the guide rod 19, preventing the limiting block 18 from shifting position during the outward movement. At this time, the limiting block 18 moving outward presses the damper 21 in the middle of the operating lever 20, and at the same time, the projector body 16 is placed on the upper side of the mounting bracket 12 along the connecting plate 17 on its outer side. By releasing the pull on the operating lever 20, the operating lever... The damper 21, which is compressed in the middle of 20, generates a rebound reaction force. At this time, the rebounding damper 21 pushes the limiting block 18 connected to its inner side to repeatedly reset inward along the guide rod 19. Due to the engaging connection between the limiting block 18 and the connecting plate 17, the limiting block 18 resetting inward engages with the connecting plate 17 and fixes it to the inner side of the mounting bracket 12. This completes the quick disassembly and assembly of the projector body 16, which makes it easy for operators to quickly disassemble and replace the projector body 16 without touching tools. This improves the maintenance and repair efficiency of the device while reducing the labor intensity of the operators and improving the utilization efficiency of the device.

[0031] Specifically, such as Figure 1 , Figure 3 and Figure 5As shown, after the installation of the projector body 16 is completed, the first drive motor 3 installed inside the anti-slip pad 2 is activated, causing the first drive motor 3 to drive the drive rod 4 connected to its upper side to rotate inside the support column 5. At this time, due to the threaded connection between the drive rod 4 and the support column 5, the rotating drive rod 4 can effectively push the support column 5 connected to its upper side to move up and down inside the base 1. Due to the sliding connection structure between the first guide block 6 and the support column 5, the support column 5 is guided and limited by the first guide block 6 during the lifting and adjusting process. At this time, the support column 5 pushes the support frame 9 and the mounting frame 12 connected to its upper side to adjust the lifting and lowering. At the same time, the second drive motor 7 installed inside the support column 5 is activated, causing the second drive motor 7 to drive the first drive disk 8 connected to its right side to rotate inside the support column 5. At this time, due to the meshing connection structure between the first drive disk 8 and the second drive disk 10, the rotating first drive disk 8 can effectively push the support frame 9 and the second drive disk 12 connected to its upper side to move up and down. The drive plate 10 is angle-adjustable, allowing operators to adjust the support height and projection angle of the projector body 16 according to the position of the projection screen. This calibrates the projection position of the projector body 16, improving the device's performance. Simultaneously, the scale 14 is mounted on the outside of the support frame 9. Due to the engaging connection between the scale 14 and the support frame 9, the scale 14 is stably fixed to the outside of the support frame 9. Rotating the mounting bracket 12 connected to the upper side of the support frame 9 causes the mounting bracket 12 to rotate within the support frame 9 along the second guide block 13 and the rotation damper 11. This causes the pointer 15 at its front end to rotate at the front end of the support frame 9. Operators can easily observe the position of the pointer 15 and the scale 14 to determine the rotational offset angle of the mounting bracket 12 and the projector body 16, thus improving the device's calibration accuracy.
