Below plate, swivel plate is connected with connecting plate by connecting portion, and described swivel plate is provided with circular hole, and described luminous plaque is away from swivel plate
One side be provided with a circle illumination LED lamp, luminous plaque is provided with measurement LED lamp near the one side of swivel plate, and described connecting plate is provided with
Photo resistance.
Described photo resistance is two.
Described circular hole is two, two Circularhole diameter differences, and one is maximum circular hole, and another is minimum circular hole.
Described photo resistance is connected with processor, and processor is connected with control unit, and control unit is connected with lens assembly.
Described photo resistance appears the measurement light change resistance come, processor according to from maximum circular hole or minimum circular hole

Brief description
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the circuit theory schematic diagram of the present invention.
Specific embodiment
As shown in figure 1, the pipe detection endoscope based on photo resistance, including endoscopic main body 1, endoscopic main body 1
Front end is provided with lens assembly 2, and luminous plaque 3 is stuck on lens assembly 2, and swivel plate 5 is stuck on lens assembly 2, and is located at luminous plaque 3
Below, swivel plate 5 is connected with connecting plate 7 by connecting portion, and swivel plate 5 is provided with two circular holes 6, the diameter of two circular holes 6
Difference, one is maximum circular hole, and another is minimum circular hole, and two circular holes 6 correspond to two limit of lens focusing respectively
Position.
Luminous plaque 3 is provided with a circle illumination LED lamp 4 away from the one side of swivel plate 5, and illumination LED lamp 4 is used for detection and illuminates,
Luminous plaque is provided with measurement LED lamp near the one side of swivel plate, and measurement LED lamp can come from circular hole 6 transmission, and connecting plate is provided with
Two photo resistance 8, when light comes from circular hole 6 transmission, the resistance of photo resistance 8 changes.Light transmittance due to circular hole 6
Difference, therefore, the resistance that photo resistance 8 receives is also different, according to the resistance of photo resistance 8, you can obtains camera lens and adjusts
Jiao is in very big limit position or minimum limit position.
Photo resistance is connected with processor, and processor is connected with control unit, and control unit is connected with lens assembly, photosensitive
Resistance changes resistance according to appearing, from maximum circular hole or minimum circular hole, the measurement light coming, and processor is by the resistance of photo resistance
It is converted into magnitude of voltage, and this magnitude of voltage is sent to control unit, above-mentioned magnitude of voltage is after control unit analysis and process to mirror
Head device is focused.
The foregoing is only the preferred embodiments of the present invention, not thereby limit the scope of the claims of the present invention, every utilization
Equivalent structure or equivalent flow conversion that description of the invention and accompanying drawing content are made, or it is related to be directly or indirectly used in other
Technical field, be included within the scope of the present invention.
