Description
Technical field
The utility model picture pick-up device field, is specifically related to a kind of mobile telephone external optical focusing camera head.
Background technology
At present, market is the mobile phone sold, and is nearly all provided with built-in camera, has shooting and shoot function, and this brings very large facility to life, can take anywhere or anytime.Along with the development of science and technology, these built-in cameras some cannot make focusing by oneself, or auto-focusing poor-performing, therefore cause shooting effect not good, shooting demand cannot be met.Although mm professional camera special can solve the problem, mm professional camera special is expensive, and carries inconvenience.
Utility model content
It is simple, easy to carry and effectively solve the mobile telephone external optical focusing camera head of embedded in mobile phone camera optical focusing poor performance that the purpose of this utility model is to provide a kind of structure.
A kind of mobile telephone external optical focusing of the utility model camera head, comprise camera and mobile phone shell, camera is connected with mobile phone shell by connection cord, camera edge is provided with projection, in mobile phone shell, the edge of built-in camera opening part is provided with the clamp corresponding with projection, and described camera is made up of the convex lens that two focal lengths are identical, and convex lens-I is arranged in lens barrel-I, convex lens-II is arranged in lens barrel-II, and lens barrel-II and lens barrel-I are threaded connection.
Distance between described convex lens-I and mobile phone optical screen is 2 times of focal length of convex lens.
Distance between described convex lens-I and convex lens-II is 1-2 times of focal length of convex lens, and the length be screwed into by the screw thread controlled between lens barrel-I and lens barrel-II, controls the distance between convex lens-I and convex lens-II.
Compared with prior art, the utility model has the advantage of: the utility model mobile telephone external optical focusing camera head, solves the problem of embedded in mobile phone camera focusing poor performance in prior art, and compact, be easy to carry; Fixed by clamp between external camera and mobile phone shell, camera install, unload convenient and swift, be applicable to different shooting demand time apply.
