Abstract
The utility model discloses a kind of pipe detection endoscope based on photoresistance, comprise endoscopic main body, endoscopic main body front end is provided with lens assembly, luminous plaque is stuck on lens assembly, swivel plate is stuck on lens assembly, be positioned at below luminous plaque, swivel plate is connected with web joint by connecting portion, described swivel plate is provided with circular hole, described luminous plaque is provided with a circle illuminating LED lamp away from the one side of swivel plate, luminous plaque is provided with measurement LED near the one side of swivel plate, and described web joint is provided with photoresistance.Advantage of the present utility model: the utility model well combines according to the characteristic of photoresistance and focus control, realizes the function of automatic focusing, stable performance, and reasonable in design, reduce manufacturing cost.
Description
Technical field
The utility model relates to detection field, specifically based on the pipe detection endoscope of photoresistance.
Background technology
Endoscope can detect crooked pipeline depths, the position that can not look at straight can be observed, interior spatial structure and state can be observed in sealed cavity, distant surveillance and operation can be realized, generally speaking technoscope detects that to apply very in industry-by-industry extensive, relate to machinery, chemical industry, automobile making, Aero-Space, the exploitation manufacture of railway engineering vehicle and haulage vehicle, the field that Maintenance and Repair etc. are different, even in the capital construction process of engineering, as the construction in bridge and tunnel, the application of industrial endoscope in maintenance, also can be found.Existing endoscope lens is that if endoscope lens focusing is focused by Hall element, camera lens needs the enough large to facilitate placement magnet of design by button or Manual mechanical focusing, so just makes lens assembly volume become large.
Summary of the invention
For solving the problem, the utility model provides a kind of pipe detection endoscope based on photoresistance.
The utility model adopts following technical scheme: based on the pipe detection endoscope of photoresistance, comprise endoscopic main body, endoscopic main body front end is provided with lens assembly, luminous plaque is stuck on lens assembly, swivel plate is stuck on lens assembly, be positioned at below luminous plaque, swivel plate is connected with web joint by connecting portion, described swivel plate is provided with circular hole, described luminous plaque is provided with a circle illuminating LED lamp away from the one side of swivel plate, luminous plaque is provided with measurement LED near the one side of swivel plate, and described web joint is provided with photoresistance.
Described photoresistance is two.
Described circular hole is two, two Circularhole diameter differences, and one is maximum value circular hole, and another is minimal value circular hole.
Described photoresistance is connected with processor, and processor is connected with control module, and control module is connected with lens assembly.
Advantage of the present utility model: the utility model well combines according to the characteristic of photoresistance and focus control, realizes the function of automatic focusing, stable performance, and reasonable in design, reduce manufacturing cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is circuit theory schematic diagram of the present utility model.
Embodiment
As shown in Figure 1, based on the pipe detection endoscope of photoresistance, comprise endoscopic main body 1, endoscopic main body 1 front end is provided with lens assembly 2, luminous plaque 3 is stuck on lens assembly 2, swivel plate 5 is stuck on lens assembly 2, and be positioned at below luminous plaque 3, swivel plate 5 is connected with web joint 7 by connecting portion, the diameter that swivel plate 5 is provided with two circular holes, 6, two circular holes 6 is different, and one is maximum value circular hole, another is minimal value circular hole, two extreme positions of two corresponding lens focusings of circular hole 6 difference.
Luminous plaque 3 is provided with a circle illuminating LED lamp 4 away from the one side of swivel plate 5, illuminating LED lamp 4 is for detecting with illumination, luminous plaque is provided with measurement LED near the one side of swivel plate, measure LED to come from circular hole 6 transmission, web joint is provided with two photoresistance 8, when light is come from circular hole 6 transmission, the resistance of photoresistance 8 changes.Because the transmittance of circular hole 6 is different, therefore, the resistance that photoresistance 8 receives also is different, according to the resistance of photoresistance 8, can obtain lens focusing and be in very big limit position or minimum limit position.
Photoresistance is connected with processor, and processor is connected with control module, and control module is connected with lens assembly.
The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model instructions and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
