[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Reference Figure 1-Figure 4An embodiment of this utility model provides an engine model exhaust nozzle simulation retraction device, including a fixed ring 1, a rotating shaft 2 rotatably connected inside the fixed ring 1, a slide rail 3 fixedly connected to the upper surface of the fixed ring 1, a rotating frame 4 fixedly connected to the outer wall of the rotating shaft 2, a blade 5, a side plate 6, and a side plate 7 slidably connected inside the rotating frame 4, the outer walls of the side plate 6 and the side plate 7 being fixedly connected to the outer wall of the blade 5, a connecting rod 8 rotatably connected to the outer wall of the rotating frame 4, a slider 9 rotatably connected to the outer wall of the connecting rod 8, the outer wall of the slider 9 slidably connected to the inner wall of the slide rail 3, a pin 10 slidably connected inside the rotating frame 4, a limiting hole 12 is opened inside the blade 5, and the outer wall of the pin 10 slidably connected to the inside of the limiting hole 12.

[0022] Specifically, side plate 6 and side plate 7 are fixedly connected to both sides of blade 5. Blade 5, side plate 6 and side plate 7 are inserted into the interior of rotating frame 4 and restricted by pin 10. Rotating blade 5 can drive rotating frame 4 to rotate. Rotating shaft 2 supports the rotation of rotating frame 4. Rotating frame 4 drives connecting rod 8 to rotate. Connecting rod 8 pushes slider 9 to slide inside slide rail 3. When pin 10 is pulled, blade 5 can be disassembled and replaced.

[0023] Reference Figure 4 The inner wall of the slide rail 3 and the outer wall of the slider 9 are both made with rough surfaces.

[0024] Specifically, slider 9 slides on the inner wall of slide rail 3. There is strong friction between slider 9 and slide rail 3, and external force needs to be applied to make slider 9 slide.

[0025] Reference Figure 1 The outer wall of side panel 6 is attached to the outer wall of side panel 7.

[0026] Specifically, in two adjacent blades 5, the side plate 7 of one blade 5 is attached to the outer wall of the side plate 6 of the other blade 5.

[0027] Reference Figure 2 The upper surface of the blade 5 is provided with a second inclined surface 14; the outer wall of the pin 10 is provided with a first inclined surface 13.

[0028] Specifically, when blade 5 is installed, inclined surface 2 14 contacts inclined surface 1 13. Pressing blade 5 down allows inclined surface 2 14 to push inclined surface 1 13 to slide, and inclined surface 1 13 drives pin 10 to slide.

[0029] Reference Figure 2 A tension spring 11 is fixedly connected to the outer wall of the pin 10, and the outer wall of the tension spring 11 is fixedly connected to the outer wall of the rotating frame 4.

[0030] Specifically, the tension spring 11 pulls the pin 10 closer to the rotating frame 4, which can prevent the pin 10 from loosening and falling off.

[0031] Working principle: When using this device, first insert the blade 5 into the inside of the rotating frame 4. The second inclined plane 14 presses the first inclined plane 13 to slide. The first inclined plane 13 first slides to the outside of the rotating frame 4, and then the tension spring 11 rebounds. The pin 10 is inserted into the inside of the limiting hole 12. When installing the blades 5, install them in sequence so that the adjacent side plates 2 7 rest on the outside of the side plate 1 6. When one of the blades 5 is moved, the blade 5 drives the side plate 2 7 of the other blade 5 to rotate through the side plate 1 6, so that all the blades 5 rotate at the same time. The rotating frame 4 and the blades 5 rotate at the same time. The rotating shaft 2 supports the rotation of the rotating frame 4. When the rotating frame 4 rotates, it will drive the connecting rod 8 to rotate. At the same time, the slider 9 slides inside the slide rail 3. When the blade 5 is released, the friction between the slider 9 and the slide rail 3 can keep the model in an open or closed state without loosening or collapsing. This device can disassemble and replace the blades 5 and can meet the requirement of rotating the blades 5 to achieve an open or closed state.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
