DETAILED DESCRIPTION

[0020] The present application will be further described in detail in combination with the drawings and preferred embodiments, and these drawings are all simplified schematic diagrams, which only schematically show the basic structure of the present application, and thus only show the relevant components.

[0021] Reference Figure 1 - Figure 4As shown, the utility model provides a technical solution: a protective device for an airborne laser radar measuring device, comprising a body 1, a laser radar device 2 is installed at the bottom of the body 1, two T-slots 3 are provided at the bottom of the body 1, a T-block 4 is slidably connected inside the T-slot 3, a protective shell 5 is fixedly connected to the bottom of the body 1, a plurality of fixed blocks 6 are fixedly connected to the bottom of the body 1, a card slot 7 is provided at one end of the fixed block 6, a hollow block 8 is fixedly connected at both ends of the T-block 4, an elliptical groove 9 is provided on one side of the hollow block 8, an adjusting rod 10 is slidably connected inside the elliptical groove 9, and a plug-in rod 11 is fixedly connected to one side of the adjusting rod 10. The staff moves the two protective shells 5 in the middle so that the protective shells 5 wrap the laser radar device 2, and then by moving the adjusting rod 10, the adjusting rod 10 drives the plug-in rod 11 to be inserted into the card slot 7 provided at one end of the fixed block 6 at the bottom of the body 1 to fix the protective shell 5. Therefore, through the setting of the protective shell 5, the laser radar device 2 can be effectively protected when not in use.

[0022] Reference Figure 3 and Figure 4 As shown, in this embodiment: the surface of the plug rod 11 is slidably connected to the inside of the slot 7, and the outer diameter of the plug rod 11 is adapted to the inner diameter of the slot 7. When the outer diameter of the plug rod 11 is adapted to the inner diameter of the slot 7, it can ensure that the plug rod 11 slides smoothly in the slot 7 and prevent the plug rod 11 from loosening during use.

[0023] Reference Figure 4 As shown, in this embodiment: one end of the plug rod 11 is fixedly connected to a return spring 14, and one end of the return spring 14 is fixedly connected to the inside of the hollow block 8. The function of the return spring 14 is to provide the plug rod 11 with a continuous outward thrust, so that when the staff releases the adjustment rod 10, the plug rod 11 can be automatically inserted into the inside of the slot 7, making it faster for the staff to use.

[0024] Reference Figure 4 As shown, in this embodiment: the top and bottom of the inner cavity of the hollow block 8 are provided with a slide groove 12, and the top and bottom of the plug-in rod 11 are fixedly connected with a slider 13, which can slide freely along the slide groove 12, thereby ensuring that the plug-in rod 11 can move flexibly in the inner cavity of the hollow block 8, thereby improving stability during adjustment.

[0025] Reference Figure 5 As shown, in this embodiment: slots 15 are provided at both ends of the T-block 4, and the internal rotating shaft of the slot 15 is rotatably connected to a rotating wheel 16. The rotation of the rotating wheel 16 can drive the T-block 4 to slide in the slot 15, reducing the friction of the T-block 4 inside the T-slot 3, making it easier for staff to save effort when adjusting.

[0026] ReferenceFigure 3 As shown, in this embodiment: the material of the protective shell 5 is high-strength aluminum alloy material. The high-strength aluminum alloy material used in the protective shell 5 provides excellent corrosion resistance and wear resistance, ensuring long-term protection of internal sensitive components. At the same time, the selection of this aluminum alloy material enables the protective shell 5 to be both lightweight and have excellent impact resistance, thereby enhancing the durability of the overall equipment.

[0027] Reference Figure 3 As shown, in this embodiment: one side of the T-block 4 is fixedly connected to a tension spring 17, and one side of the tension spring 17 is fixedly connected to the inside of the T-slot 3. The function of the tension spring 17 is to provide a continuous tension for the T-block 4 to ensure that the T-block 4 can slide stably in the slot 15. At the same time, after the protective shell 5 is opened, the tension spring 17 can help the T-block 4 to quickly return to the initial position, thereby improving the adjustment efficiency.

[0028] Working principle: The staff moves the two protective shells 5 in the center so that the protective shells 5 wrap the laser radar device 2, and then moves the adjusting rod 10 to drive the adjusting rod 10 to drive the connecting rod 11 and insert it into the slot 7 opened at one end of the fixing block 6 at the bottom of the body 1 to fix the protective shell 5. Therefore, through the setting of the protective shell 5, the laser radar device 2 can be effectively protected when not in use. When the outer diameter of the connecting rod 11 matches the inner diameter of the slot 7, it can ensure that the connecting rod 11 slides smoothly in the slot 7 and prevents the connecting rod 11 from loosening during use. The function of the return spring 14 is to provide a continuous outward thrust for the connecting rod 11, so that when the staff releases the adjusting rod 10, the connecting rod 11 can be automatically inserted into the inside of the slot 7, making it faster for the staff to use. The slider 13 can slide along the slide The slot 12 slides freely, thereby ensuring that the plug-in rod 11 can move flexibly in the inner cavity of the hollow block 8, thereby improving the stability during adjustment. The rotation of the rotating wheel 16 can drive the T-block 4 to slide in the slot 15, reducing the friction of the T-block 4 inside the T-slot 3, making it easier for staff to adjust. The high-strength aluminum alloy material used in the protective shell 5 provides excellent corrosion resistance and wear resistance, ensuring long-term protection of internal sensitive components. At the same time, the selection of this aluminum alloy material makes the protective shell 5 both lightweight and has excellent impact resistance, thereby enhancing the durability of the overall equipment. The function of the tension spring 17 is to provide a continuous tension for the T-block 4, ensuring that the T-block 4 can slide stably in the slot 15. At the same time, after the protective shell 5 is opened, the tension spring 17 can help the T-block 4 quickly return to its initial position, thereby improving the adjustment efficiency.
