Abstract
The utility model provides an optical reflector of a projector, which comprises a reflector, a plurality of support parts and a base, wherein the support parts are mounted on the base and the reflector is directly mounted on the support parts. The optical reflector of the projector has the advantages that the support parts are mounted on the base and directly contact with the reflector, the reflector can be adjusted more directly and effectively through the support parts, and adjustment effect can be improved by means of further adding pads to one or multiple positions of the support parts contacting with the reflector.
Description
Technical field
The utility model relates to a kind of optical mirror of projector, particularly about a kind of optical mirror of easy-to-install projector.
Background technology
Projector is the same with slide projector, also is to utilize the convex lens image-forming principle, and transparent object is projected in the screen, forms enlarged image.Projector mainly is made of optical system, ventilation equipment and circuit.The optical system that obtains projector has installed the plane mirror of an adjustable-angle additional, will be transformed into the horizon light axis from the vertical light axis of condenser.Therefore lantern slide becomes level by vertically putting upside down and just puts, and obtains the erect image that amplifies in screen, and the teacher can be demonstrated while explaining in the face of the student, and is very convenient.Projector must be opened plane mirror before start, guarantees to guide the light of light source ejaculation into screen after the start, and hot spot is appeared in the screen; Do not open as if plane mirror, it reflects back into light source again with the light that light source penetrates the start back, with the light source table surface temperature, influences the life-span of projector in the increase machine.
It shown in the accompanying drawing 1 a kind of structure that has the optical mirror of optics adjustment structure in the prior art, for catoptron 11 is fixed on above the mirror support 12, then catoptron 11 and mirror support 12 are installed on the pedestal 13, and on the basis of pedestal 13, the position of catoptron 11 is adjusted by the mode of on pedestal 13, adding pad 131,132 and 133.This structure is from assembling more complicated, and at mirror support 12 and pedestal 13 product requirement higher processing precision.
In view of this, how to invent new adjustment structure, solve the defectives such as assembling complexity of prior art, become the problem that current programme presses for solution.
The utility model content
Technical problem to be solved in the utility model is that a kind of optical mirror of easy-to-install projector is provided.
In order to address the above problem, the utility model provides a kind of optical mirror of projector, comprises catoptron, a plurality of support member and pedestal, and support member is installed on the pedestal, and catoptron is directly installed on the support member.
Optionally, the number of described support member is 3.
Optionally, described support member is isosceles triangle and arranges on pedestal.
Optionally, further be provided with pad between described support member and the catoptron.
Advantage of the present utility model is, support member is installed on the pedestal and directly contacts with catoptron, it is more direct effectively directly to adjust catoptron by support member, even can pass through further one or several in support member and catoptron position contacting increase pad, improve the effect of adjustment.
Description of drawings
It shown in the accompanying drawing 1 a kind of structure that has the optical mirror of optics adjustment structure in the prior art.
Be to have the exploded view that optics is adjusted the optical mirror of structure in the utility model embodiment shown in the accompanying drawing 2.
Accompanying drawing 3 is that support member is installed in structural representation on the pedestal.
Accompanying drawing 4 is that structure shown in the accompanying drawing 3 has further been installed catoptron structural representation afterwards.
Embodiment
The embodiment of the optical mirror of the projector that the utility model is provided below in conjunction with accompanying drawing elaborates.
Be a kind of exploded view that has the optical mirror of optics adjustment structure in the utility model embodiment shown in the accompanying drawing 2, comprise catoptron 21, support member 221,222 and 223, and pedestal 23.Accompanying drawing 3 is support member 221,222 and 223 to be isosceles triangle be installed in structural representation on the pedestal 23, and accompanying drawing 4 is structural representations of further having installed after the catoptron 21.
Comprehensive accompanying drawing 2 to accompanying drawing 4 as can be seen, the support member 221,222 and 223 of this embodiment is installed on the pedestal 23 and directly contacts with catoptron 21, it is more direct effectively directly to adjust catoptron 21 by support member 221,222 and 223, even can pass through further one or several in support member 221,222 and 223 and catoptron 21 position contacting increase pad, improve the effect of adjustment.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
Claims (4)
1. the optical mirror of a projector is characterized in that, comprises catoptron, a plurality of support member and pedestal, and support member is installed on the pedestal, and catoptron is directly installed on the support member.
