[0011] 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.
[0012] Reference Figure 1 , Figure 2This utility model provides an embodiment of a flight spoiler protractor fixing tool, including a fixing plate 1, which is a rectangular metal plate used to support various components and serves as the basic support structure for the entire tool. A fixing component 2 is fixedly connected to the bottom of the fixing plate 1 to securely install the entire tool at the target position. A clamping component 3 is fixedly connected to the top of the fixing plate 1, enabling clamping and releasing of the protractor device 4. The protractor device 4 is mounted on the top of the clamping component 3 for accurately measuring the angle of the flight spoiler. Two connecting bolts 6 are internally threaded onto the fixing plate 1, symmetrically distributed along the length of the fixing plate 1. These two connecting bolts 6 connect the fixing plate 1 to the bottom of the protractor device 4. The two connecting bolts 6 are externally threaded onto the bottom of the protractor device 4, allowing the protractor device 4 to be securely mounted on the fixing plate 1. The fixing component 2 includes a fixing body. 21. The main body 21 of the fixing component is a cylindrical structure that provides support. The top of the fixing component 2 is fixedly connected to a suction cup boss 25. The suction cup boss 25 is a circular protrusion used for connection and fixation. The top of the suction cup boss 25 is threadedly connected to four fixing bolts 5. The four fixing bolts 5 are arranged in a rectangle to tightly connect the main body 21 of the fixing component to the fixing plate 1. The external threads of the four fixing bolts 5 are connected to the top of the fixing plate 1 to ensure a stable and reliable connection. The external of the main body 21 of the fixing component is slidably connected to a suction cup knob 22. The suction cup knob 22 can rotate around the axis of the main body 21 of the fixing component to release air. Turning it to the left will cause the rubber suction cup 23 to tighten, and turning it to the right will cause the rubber suction cup 23 to release air. The bottom of the main body 21 of the fixing component is fixedly connected to a rubber suction cup 23. The rubber suction cup 23 has a bowl-shaped structure that can generate vacuum suction force. The external of the rubber suction cup 23 is provided with a venting handle 24. The venting handle 24 can be turned to allow the suction cup to quickly enter air and release the suction.
[0013] Reference Figure 1 , Figure 3 , Figure 4The clamping assembly 3 includes a rectangular mounting frame 31, which is a hollow frame used to mount the protractor. The bottom of the rectangular mounting frame 31 is fixedly connected to the top of the fixed plate 1. A threaded rod 33 is slidably connected inside the rectangular mounting frame 31 and can move along its own axis. Two clamping plates 35 are slidably connected outside the threaded rod 33. The two clamping plates 35 are L-shaped and can move relative to each other. Their horizontally similar sides are set outside the rectangular mounting frame 31. A threaded knob 32 is threadedly connected to the outside of the threaded rod 33. Rotating the threaded knob 32 can push the threaded rod 33 to move. Two springs 34 are sleeved on the outside of the threaded rod 33. The two springs 34 can generate elastic force to achieve reset. Their ends are fixedly connected inside the rectangular mounting frame 31. The bottoms of the two clamping plates 35 are slidably connected to the top of the fixed plate 1 and can slide along the surface of the fixed plate 1. Two guide posts 36 are provided inside the rectangular mounting frame 31. The cylindrical clamp 35 serves as a guide, and its interior is slidably connected to the exterior of the two guide posts 36, allowing it to slide along the axis of the guide posts 36. Both sides of the guide posts 36 are fixedly connected to stop blocks 37, which are circular and limit the sliding range of the clamp 35. The protractor device 4 includes a protractor body 41, which is a cuboid used for angle measurement. Its bottom is positioned on top of a rectangular mounting frame 31. A display screen 42 is located on the front exterior of the protractor body 41. The rectangular display screen 42 displays measurement data. A switch button 43 is located on the left side of the display screen 42, which can be pressed to control the start and stop of the protractor. A zeroing button 44 is located on the right side of the display screen 42, which can be pressed to zero the measurement. The rear side of the zeroing button 44 is fixedly connected to the front side of the protractor body 41. The two clamps 35, with their horizontally similar distance, contact the exterior of the protractor body 41, clamping and fixing it in place.
[0014] Working principle: The rubber suction cup 23 is attached to the surface of the flight spoiler. The suction cup knob 22 is slid to release the air inside the rubber suction cup 23 through the manual knob-type exhaust mechanism, creating a vacuum state and generating an adsorption force of ≥85kPa, thereby firmly fixing the main body 21 of the fixing component and the entire tool to the spoiler. When disassembly is required, the air release handle 24 is operated to allow air to enter the rubber suction cup 23 and release the adsorption state. The suction cup boss 25 is connected to the fixing plate 1 by four fixing bolts 5 to ensure the connection stability between the fixing component 2 and the fixing plate 1. After the protractor device 4 is placed on top of the rectangular mounting frame 31, the threaded knob 32 is rotated to push the threaded rod 33 to slide within the rectangular mounting frame 31. The threaded rod 33 drives the two clamping plates 35 to move along the guide post 36, while simultaneously compressing the spring 34. When the threaded knob 32 is rotated in the opposite direction, the spring 34 returns to its original position and generates elastic force, driving the clamping plates 35 to move in the opposite direction, thereby clamping and releasing the protractor body 41. The stops 37 at both ends of the guide post 36 are used to limit the sliding range of the clamping plates 35, ensuring that the clamping action is accurate and controllable. The protractor body 41 is clamped and fixed by the two clamping plates 35 of the clamping assembly 3, and further fixed to the fixing plate 1 by the two connecting bolts 6, ensuring that the position is stable during the measurement process. Pressing the switch button 43 starts the protractor body 41, which detects the angle of the flight spoiler. The detection data is displayed in real time on the display screen 42. Before measurement, the zeroing button 44 can be pressed to perform a zeroing operation to ensure measurement accuracy.
[0015] 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.
