Abstract

A three-dimensional projectors consists of a shell, projectors, polarized lenses and a projection screen, the projection screen and the projectors are located in front of the shell and behind the shell respectively, the polarized lenses are located in front of the camera lens of the projectors, the numbers of the projectors and the polarized lenses are both 2, the level axes of the two projector are intersecting, the projector image are in superposition. The utility model provide a three-dimensional projectors with simple structure, which is suitable for variety of sites, and has the advantages that the viewing distance is far, the vision is not easy to be damaged, and the utility model is non-radiation safety and particularly suitable for the household three-dimensional projection equipment.

Description

Binocular projector

The utility model relates to image and plays facility, belongs to the vision facilities technical field.

TV is that the image of present widespread use is play facility, though it has the picture and the abundant colors of high definition, but, it offered is still plane picture, progress along with science and technology, people no longer satisfy the appreciation of simple plane picture, but appreciate people's that stereoscopic picture plane brings impression true to nature on the spot in person more.In early time, stereophonic cinema was arranged once, but it needs people to go to special movie theatre to watch, very inconvenient.Along with growth in the living standard, stereo-picture playback equipment easy to use has the enormous and latent market demand.For satisfying people visual perception's diversified demand, further enrich people's culture life, should develop this series products as early as possible.

The purpose of this utility model is to provide a kind of stereoscopic image projector, characteristics simple in structure, easy to use, easy operating that this projector should have.

The purpose of this utility model is achieved in that

A kind of binocular projector, it comprises housing 1, projector 2, polarized lenses 3, projection screen 4 in constituting, projection screen and projector lay respectively at the forward and backward side of housing, polarized lenses is positioned at the projection lens front of projector, the quantity of projector and polarized lenses respectively is 2, and the horizontal axis of 2 projector intersects, projected image overlaps on projection screen.

Above-mentioned binocular projector, the bottom of described 2 projector is respectively equipped with bolt 5, and described housing rear is provided with saddle 6, is symmetrical arranged 2 screw 6-1 on the saddle, and screw is a Long Circle, and bolt 5 is arranged in screw.

The utility model is adopted science such as projector and polarized lenses, projection screen is combined, and a kind of stereoprojection equipment simple in structure is provided, and this projector contour structure size is changeable, and multiple place can suit.In addition, it is far away that it also has viewing distance, easy damaged eyesight not, and radiationless good safe application performance suitablely especially uses as family expenses stereoprojection equipment.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the utility model structural representation;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is the johning knot composition of projector and horizontal saddle;

Fig. 4 is the upward view of Fig. 3;

Fig. 5 is the utility model three-dimensional imaging schematic diagram.

Consult Fig. 1,2, among the figure, projection screen 4 is fixed on the shell wall in housing the place ahead, and 2 projector 2 are horizontal projector, are placed on the housing wall at housing rear side by side that polarized lenses 3 is installed on the projection lens front end of projector by eyeglass cover 7.

Consult Fig. 3,4, among the figure, bolt 5 upper ends are the dull and stereotyped 5-1 of a larger area, and this flat board can be circle or rectangle, and projector is fixedlyed connected with this plate; Saddle 6 be horizontal saddle, can with the housing integral molded plastic, also can be used as independent member and be installed on the housing; Bolt 5 can freely rotate in Long Circle screw 6-1 and move forward and backward, can regulate angle that 2 projector horizontal axiss intersect easily and apart from the distance of projection screen, the projected image of 2 projector is overlapped on projection screen, after regulating, can by nut 7 with bolted on saddle.

Consult Fig. 5, principle of work of the present utility model is: projector is connected with televisor or VCD by circuit, the numerical information that receives is converted into image information, and project image onto on the projection screen by polarized lenses, 2 one of polarized lenses are vertically placed, another horizontal positioned, the former allows vertical light to pass through, the latter allows horizontal light to pass through, 2 projector overlap on projection screen through the light of polarized lenses projection and are piece image, and refract on the polarising glass respectively, 2 polarized lenses of polarising glass also are one vertically to be settled, another horizontal setting, vertically the polarized lenses of settling receives vertical refracted ray, the polarized lenses of horizontal setting receives horizontal refraction light, refracted ray vertical and level enters people's a left side respectively, right eye, two optical information of slightly having any different formation one perfect stereo-pictures after brain is synthetic that eyes are watched.

The utility model need be used the glasses of polarized lenses when playing stereoscopic picture plane, the glasses of polarized lenses can be used as annex of the present utility model and sell at random, also can be independent product and are matched by client.
