Description

Technical Field

[0001] The invention belongs to the technical field of aviation assembly and relates to a telescopic inspection mirror device with an adjustable light source. Background Art

[0002] Inspection mirrors are tools used in aircraft auxiliary processing and quality inspection. They facilitate observation of small parts of the aircraft and allow direct inspection of the quality of fastener connections, parts installation, insurance quality, surface protection, etc. in inaccessible areas. They have a wide range of applications.

[0003] In actual production, structures such as narrow structures, complex parts, backs, curved surfaces, and semi-enclosed areas are often accompanied by insufficient light. The inspection mirror will be affected by the light when in use, making it difficult to see the image on the inspection mirror clearly. This greatly increases the difficulty for users to process and inspect the observed parts and also reduces the quality of the processed products and the accuracy of quality inspection. Although the existing LED inspection mirror has LED lights around the mirror to achieve lighting, the lights on the mirror frame will cause the mirror frame to be too wide, resulting in the inability to directly illuminate the bottom when using the inspection mirror to observe the root of the workpiece, and blind spots are prone to occur in narrow areas with limited space. LED inspection mirrors also have disadvantages such as the distance between the light source and the inspection mirror, the angle cannot be adjusted, the illumination range is limited, the light source is scattered, and the brightness is insufficient. If processing and inspection are carried out with a flashlight, the above problems can be improved, but one hand is required to hold the inspection mirror and the other hand to hold the flashlight, and other operations cannot be performed. More people are required to participate in the operation, which greatly reduces work efficiency and is time-consuming and labor-intensive.

[0004] In summary, the existing technology has problems such as unclear imaging due to insufficient light, inconvenient and inflexible use, difficulty in efficiently, accurately and conveniently observing areas with insufficient light in a low-cost manner, and complex, closed structures and inaccessible areas. This affects product processing quality and inspection accuracy, resulting in low work efficiency and high labor costs. Summary of the Invention

[0005] The present invention provides a telescopic inspection mirror device with an adjustable light source. The inspection mirror and lighting device can be freely extended to any length, rotated at any angle, adjusted in any direction, and positioned relative to each other. The device also allows for free adjustment of the light source's illumination distance, angle, and range. This device is suitable for the production, processing, and product acceptance of various structures, including those with narrow or complex structures, back surfaces, curved surfaces, and semi-enclosed areas. This effectively solves the problem of unclear imaging due to insufficient light, resulting in inconvenient and inflexible use, which affects product processing quality and inspection accuracy, leading to low work efficiency and high labor costs.
