The specific embodiment
With reference to Fig. 1-Fig. 4 and shown in Figure 7, zoom formula optical lens has a shell 1, this shell 1 is made of camera lens upper casing 101 and camera lens lower casing 102 movable pegging graft, the moulding ring set of camera lens upper casing 101 one has camera lens focusing ring 103, the axis place of camera lens lower casing 102 has camera lens draw-in groove 104 (see figure 7)s, camera lens cone 2 constitutes (see figure 3) by camera lens body 201 and lens focus bar 202, and the lens focus bar 202 and the camera lens draw-in groove 104 movable rails of camera lens cone 2 connect (see figure 4).
Extremely shown in Figure 6 with reference to Fig. 5, technological improvement of the present utility model is, in the circle scope of inwall from top to terminal 360 degree of camera lens upper casing 101, design has a twill elongated slot 105, lens focus bar 202 movable rails are connected on the twill elongated slot 105, when rotating lens focusing ring 103, lens focus bar 202 is made screw movement along twill elongated slot 105, again power is conducted to camera lens body 201, make camera lens body 201 in camera lens draw-in groove 104, make screw movement, thereby change the focal length and the object distance of camera lens, change the camera lens multiple, realize 1 times successively, the adjusting of 50 times and 300 times three kinds of multiplication factors.
Extremely shown in Figure 12 with reference to Fig. 8, be provided with light source holder 106 in the front end of camera lens lower casing 102, be arranged with six small light source lamp hole positions 107 in light source holder 106 end faces, corresponding six the small light source lamps 108 that light source is provided for the camera lens cone that are inserted with on the small light source lamp hole position 107, this illuminator adopts the LED lamp; The periphery is provided with as if six big light source lamp hole positions 109, and the promising camera lens cone of corresponding inserted provides six big illuminators 110 of light source on the big light source lamp hole position 109, and this illuminator adopts the LED lamp equally.Below camera lens cone 2, be provided with first polaroid of regulating camera lens cone 2 polarisation effects, camera lens lower casing 102 interior belows in light source holder 106 coincide and are embedded with second polaroid 111, second polaroid 111 around edge have six perforates 112, camera lens cone 2 polarisations and the not switching of polarisation effect can be realized by being used of first and second polaroid in the position of six perforates 112 and aperture and big light source lamp hole position 109 corresponding coincideing.During as need polarisation effect, second polaroid 111 maintains static moving, only needs to switch six small light source lamps 108 and six big illuminators 110 by power switch.Bright when interior six small light source lamps 108 that enclose, small light source lamp 108 is blocked by second polaroid 111, and light forms the polarisation effect via the refraction of first polaroid and second polaroid 111; When the big illuminator of six of periphery 110 is bright and six small light source lamps 108 are closed, because big illuminator 110 is not blocked by second polaroid 111, light only passed through first polaroid of camera lens cone and without second polaroid 111, did not then produce the polarisation effect this moment.Utilize electronic switch type control light source to reach the convenient purpose of switching the polarisation effect, not only quick and convenient, and also accurate.
With reference to Fig. 1 and shown in Figure 13, also design on this optical lens structure a lens cap 3 is arranged, the middle part of lens cap 3 has an endoporus 301, this lens cap 3 and camera lens lower casing 102 pivot bush units, size is just coincide, when selecting 50 times of focal lengths with 300 times to observe, can cover lens cap 3, so whole optical lens can be placed on observed object (as skin or hair) and go up as the strong point, serve as the stability of relying on when reaching the focal length location with this strong point, makes observation more accurate, more accurate.When selecting 1 times of focal length to observe, because of 1 times of focal length needs the object lens scope big, take off lens cap 3 this moment, prevents that endoporus 301 edges of lens cap 3 from having blocked the camera lens visual angle, load and unload nimblely, and it is reasonable to construct.
The utility model can be applicable to skin, hair detection instrument or the fields such as hiccough, industrial microscope in medical science or the beauty treatment.
The utility model includes but not limited to that the foregoing description lifts, and the structure of any effects equivalent based on the conversion of the technical program institute all belongs to protection domain of the present utility model.
