Abstract
The utility model relates to a binocular wide-angle magnifier which is composed of an object lens, a prism and two eye lenses. Two symmetry type double-glued eye lenses which are composed of four eye pieces are installed into two eye lens. Two lens tubes are connected with each other by a hinge and interpupillary adjustment can be realized as the two lens tubes rotate around a hinge axis. A prism combination is installed on the middle part of each lens tube and an object lens combination is installed on the lower part of each lens tube. The object lens combination is installed on an object lens mount. The object lens and the object lens mount are connected into one body through a sliding pin and a focusing ring. The object lens is adjusted by a focusing hand wheel to move upwards and downwards to enlarge the range of visibility. The binocular wide-angle magnifier has the advantages of imaging clearness and wide visual angle, and enlarges the range of visibility to 30 cm to 50 cm, being suitable for people who stand to work and sit to work. The utility model can be used in various industries, such as medical industry, etc.
Description
The utility model relates to bitubular wide-angle magnifier.
In the prior art, the U.S., Germany, Japan, Tianjin medical optical instrument factory, the medical operation magnifier that the ZL95245534X utility model patent that Patent Office of the People's Republic of China is authorized etc. are produced both at home and abroad, its structure is similar, mainly be divided into two big classes, one class is to adopt object lens, eyepiece optical system, another kind of is to use object lens, prism, eyepiece is formed optical system, no matter above-mentioned shortcoming of the common existence of which kind of optical system is that optical system is when assembling, object lens, eyepiece or prism are to fix in the dust in lens barrel, that is to say a changeless optical system, its sighting distance and operating distance are selected just and are determined in this usable range of having an operation, diopter generally can not be adjusted, for different human eye diopters, can only be adjusted by lengthening or the distance that shortens between scenery and the human eye, for example the sighting distance of the U.S. is determined at 47 centimetres, German is 45 centimetres, Tianjin be 42 centimetres, Zhulin Electronic Co., Ltd., Xian (ZL95245534.X) is 45 centimetres, above-mentioned various sighting distances are this usable range of standing and having an operation just, and people's height, arm sample different in size, especially some operation or the other industry work post work that need be seated, the usable range of this product just is restricted greatly, and adaptedness is poor.
The purpose of this utility model is to provide a kind of field angle big, and the optical system that range of observation is wide, sighting distance is adjustable adapts to the multi-functional wide-angle magnifier of the duty of standing or be seated.
Realize that the technical solution of the utility model is to solve like this: a left lens barrel connects a structure and the identical right lens-barrel of left lens barrel by hinge axis, set nut, left and right lens barrel all is made of the light path system structure of symmetry objective lens, prism group, eyepiece group, its eyepiece group is fixed on the eyepiece stalk by spacer ring, eyepiece trim ring, isosceles roof prism, half pentagonal prism are fixedly installed in the middle part of left and right lens barrel by prism table, prism trim ring with the prism group, and objective lens is installed in the bottom.Improvements of the present utility model are that above-mentioned said eyepiece is made up of at least four symmetrical two gummed eyepieces, said object lens are fixedly mounted in the objective holder behind gummed, whole objective lens is to fuse with focusing ring by the nail that slides, focusing ring is connected with focusing handwheel, compresses focusing handwheel and prism trim ring with fixing trim ring.When rotating focusing handwheel, because objective lens is to be connected one with focusing ring, the nail that slides, this moment, objective lens just moved up and down along primary optical axis, adjusted diopter and regulated sighting distance thereby reach.
The utility model compared with prior art, eyepiece group and objective lens have been carried out improving design, the eyepiece group makes four types into by two～three types, help the raising of image quality, objective lens makes adjustable interior focusing system into, and focus adjusting mechanism can make object lens move up and down along primary optical axis, makes range expansion to 30～50 centimetre of sighting distance, adjustable arbitrarily, overcome the deficiencies in the prior art.Simultaneously, distance between the prism group has also been made adjustable technological improvement, the improvement of comprehensive above-mentioned every technology, the utlity model has rational in infrastructure, volume is little, and field angle is big, and the sighting distance setting range is wide, imaging is characteristics clearly, when it can adapt to the people and is seated duty (30～35 centimetres) and the duty of standing (35～50 centimetres) scenery are amplified and have realized wide-angle.Be widely used in electronics industry, horological industry, precision optical machinery manufacturing industry, the photoelectricity industry detects the metering industry, medical and health industry, geology industry etc.
Optical property of the present utility model is:
17 millimeters of enlargement ratio 3.3 * distances of exit pupil
56～74 millimeters of field angle 130 center interpupillary distances
30～50 centimetres of 5 centimetres of sighting distances of magnifier length overall
