[0023] like Figure 1 and Figure 2 As shown, this utility model provides a base for a navigation light, comprising:

[0024] The bottom plate 1, the barrel body 2, and the flange 3 are arranged sequentially from bottom to top;

[0025] The bottom plate 1 is welded to the lower end of the barrel body 2, and a first full welded part 4 and a second full welded part 5 are respectively provided inside and outside the base;

[0026] The upper end of the barrel body 2 is threadedly connected to the flange 3, and a third full weld part 6 and a fourth full weld part 7 are respectively provided inside and outside the base.

[0027] Specifically, to address the problem of weld breakage and detachment of the flange 3 at the upper end of the barrel 2 of the navigation light base in the prior art, which affects aircraft operation, the navigation light base provided by this utility model uses a threaded connection between the upper end of the barrel 2 and the flange 3 to ensure that the two can fit tightly and be tightened, which can improve the stability of the connection and enhance the overall strength of the base. In addition, based on the threaded connection, the base is fully welded inside and outside, providing all-round welding strength and effectively preventing breakage caused by stress concentration. At the same time, the bottom plate 1 and the lower end of the barrel 2 are fully welded inside and outside to ensure the strength and sealing of the connection between the bottom plate 1 and the lower end of the barrel 2, preventing leakage or breakage caused by welding defects.

[0028] Optionally, it also includes a positioning piece 8, the upper and lower ends of which are welded to the flange 3 and the barrel body 2, respectively.

[0029] Specifically, the positioning piece 8 has sufficient strength and rigidity. By welding the flange 3 to the barrel 2 through the positioning piece 8, the connection structure between the two can be further strengthened, preventing loosening or breakage caused by vibration or impact.

[0030] In this embodiment, the material of the positioning piece 8 is the same as that of the barrel body 2, the flange 3 and the base plate 1, and its specifications are 20mm×75.58mm×2mm.

[0031] Optionally, multiple positioning pieces 8 are provided, and the multiple positioning pieces 8 are evenly distributed along the circumference of the base.

[0032] Specifically, the circumferentially distributed positioning plates 8 can uniformly strengthen the connection between the barrel body 2 and the flange 3.

[0033] In this embodiment, four positioning pieces 8 are provided.

[0034] Optionally, the lower end face of the barrel 2 is aligned with the upper surface of the base plate 1.

[0035] Specifically, the base plate 1 is flat and can be welded to the lower end of the barrel body 2.

[0036] Optionally, the upper inner circumference of the barrel body 2 is provided with a first threaded portion 9, the lower end of the flange 3 is provided with an annular boss 10, the outer circumference of the boss 10 is provided with a second threaded portion, and the first threaded portion 9 is connected to the second threaded portion.

[0037] Specifically, the outer diameter of the boss 10 is smaller than the outer diameter of the flange 3, the outer diameter of the flange 3 is equal to the outer diameter of the barrel 2, and when the flange 3 is threadedly connected to the barrel 2, the first threaded part 9 is fitted onto the outside of the second threaded part.

[0038] Optionally, the positioning piece 8 is welded to the outside of the barrel body 2 and the flange 3.

[0039] Specifically, the positioning piece 8 is welded to the outside of the barrel body 2 and the flange 3, and the shape of the positioning piece 8 is an arc shape that matches the shape of the barrel body 2 and the flange 3.

[0040] Optionally, the two horizontal edges of the positioning piece 8 are fully welded to the flange 3 and the barrel 2 respectively, forming a fifth full weld portion 11 and a sixth full weld portion 12 respectively. The two vertical edges of the positioning piece 8 are spot welded to the flange 3 and the barrel 2 respectively, and spot weld portions 13 are formed at intervals on both sides of the positioning piece 8.

[0041] Specifically, the positioning piece 8 is welded to the flange 3 and the barrel 2 by full welding at the top and bottom ends and electric welding on the left and right sides, which strengthens the connection between the flange 3 and the barrel 2.

[0042] Optionally, the flange 3 is provided with multiple mounting holes 14, and the base plate 1 is provided with a cable outlet hole 15.

[0043] Specifically, mounting hole 14 is used to install navigation lights, and cable outlet hole 15 is used for the secondary cable outlet of the navigation lights.

[0044] In this embodiment, the flange 3 above the barrel 2 and the upper end of the barrel 2 are threaded to form external and internal threads. After the flange 3 is tightened to the barrel 2, the connection is fully welded inside and out. The welding of the bottom plate 1 and the lower end of the barrel 2 is also done by fully welding inside and out to ensure the strength and sealing of the connection.

[0045] In this embodiment, it also includes:

[0046] Provide a positioning piece 8, and weld the upper and lower ends of the positioning piece 8 to the flange 3 and the barrel body 2 respectively.

[0047] Specifically, a positioning piece 8 of a specified size and shape is selected and attached to the connection between the flange 3 and the barrel 2. The upper and lower parts are welded and the sides are spot welded to reinforce the connection structure in one step and prevent the flange 3 from loosening or breaking due to vibration or impact.

[0048] In addition, during the actual base manufacturing process, the selection of materials must ensure that they possess sufficient strength and toughness to withstand the weight of the aircraft and potential impact loads. Material performance testing can be conducted if necessary to verify their reliability. Regarding welding quality control, welding parameters (such as current, voltage, and welding speed) should be strictly controlled during the welding process to ensure quality. Necessary inspections and evaluations of the weld joints, such as X-ray and ultrasonic testing, should be performed to ensure they are defect-free. For structural design optimization, in addition to the above improvements, the overall structure of the base can be optimized, such as by adding reinforcing ribs or changing the cross-sectional shape, to further improve the strength and stability of the structure.

[0049] In summary, by implementing the above processing methods, the robustness and reliability of the connection structure between the flange 3 and the barrel 2 can be significantly improved, thereby meeting the weight load requirements of aircraft. At the same time, attention should also be paid to strictly adhering to relevant standards and specifications during the design and manufacturing process to ensure the quality and safety of the product.

[0050] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
