Some cameras are equipped with color-changing lamp, and color-changing lamp needs to discharge substantial amounts of heat at work, cause the temperature of camera lens rapid
Rise, with the change of temperature, its image quality can be affected traditional lens barrel.
In summary, color-changing lamp needs to discharge substantial amounts of heat at work, causes the temperature of camera lens to raise rapidly, tradition
Lens barrel with the change of temperature, its image quality can be affected.
The content of the invention
The utility model needs to discharge substantial amounts of heat at work to solve color-changing lamp, causes the temperature of camera lens to rise rapidly
Height, traditional lens barrel with the change of temperature its image quality can affected technical problem and provide it is a kind of it is simple in construction,
Wide-angle optical lens that are easy to install, improving operating efficiency.
The utility model is adopted the technical scheme that to solve technical problem present in known technology：
Wide-angle optical lens provided by the utility model, the wide-angle optical lens are provided with：
One lens barrel；
At least one diaphragm knob is embedded in the lens barrel of movable block side；

Further, described two diaphragm knobs are embedded in the lens barrel of movable block side.
Further, a focusing knob is embedded on the lens barrel of control column offside.
Further, described focusing knob one end is provided with anti-slip tank.
The utility model has the advantages and positive effects of：Because the utility model passes through focusing knob and diaphragm knob
Cooperation, realize the focusing to optical lens and Illumination adjusting function, ensure that the quality of taking pictures of optical lens；Focusing knob
On anti-slip tank improve the frictional force of focusing knob, ensure that the normal use of focusing knob；Lens barrel is protected inside camera lens
All parts from the interference of external environment condition, ensure that internal part normal use.
