Abstract
The utility model provides a splicing wall reflector structure, belonging to the technical filed of reflector structure. The reflector structure comprises a reflector back frame, a reflector, a reflector top adjusting piece, a reflector left adjusting piece, a reflector right adjusting piece and adjusting screws, wherein the reflector is arranged in the reflector back frame, the reflector top adjusting piece is fixed on the top of the reflector back frame, the reflector left adjusting piece and the reflector right adjusting piece are fixed on the left side and right side of the reflector back frame, and the adjusting screws are arranged on the reflector top adjusting piece, the reflector left adjusting piece and the reflector right adjusting piece. The beneficial effects of the utility model are that, the inclination of the reflector is adjustable so as to correct the deviation caused by the deformation of the reflector, thereby ensuring the boundary dimension of the image, and ensuring the integrity of the image of the back projection splicing wall. The problem of imaging deviation of the back projection splicing wall resulting from the angle deviation of the reflector is solved.
Description
Technical field
The utility model relates to a kind of combination mirror structure, belongs to the mirror structure technical field.
Background technology
The imaging of rear-projection combination is to utilize the reflection of light principle, and the content of ray machine output is through projecting to after the mirror reflects on the imaging curtain, and consistent with sideline around the imaging curtain in order to make image, the angle of catoptron requires stricter.Existing catoptron because mirror size is larger, metaboly can occur, so the angle difference of catoptron is very large after being fixed on back projection box body inside in the mode that tilts, and causes image deviation can occur.
Summary of the invention
The purpose of this utility model is for after solving existing catoptron and being fixed on back projection box body inside in the mode that tilts, because mirror size is larger, metaboly can occur, the angle difference of catoptron is very large, cause image the problem of deviation to occur, and then a kind of combination mirror structure is provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of combination mirror structure, comprise: catoptron backrest, catoptron, catoptron top adjustment part, catoptron left and right sides adjustment part and set screw, described catoptron is arranged in the catoptron backrest, catoptron top adjustment part is fixed on the top of catoptron backrest, catoptron left and right sides adjustment part is fixed on the left and right sides of catoptron backrest, is respectively equipped with set screw on catoptron top adjustment part and the catoptron left and right sides adjustment part.
The utlity model has following advantage: catoptron of the present utility model can be adjusted the angle of inclination, proofreaies and correct the deviation that causes owing to catoptron deformation, guarantees the physical dimension of image, guarantees the integrality of rear-projection combination image.Solved the problem of the deviation of the rear-projection combination imaging that the deviation owing to mirror angle causes.
Description of drawings
Fig. 1 is the structural representation of each parts of combination mirror structure of the present utility model;
Fig. 2 is the synoptic diagram of combination mirror structure.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail: present embodiment is implemented under take technical solutions of the utility model as prerequisite, has provided detailed embodiment, but protection domain of the present utility model is not limited to following embodiment.
As depicted in figs. 1 and 2, a kind of combination mirror structure that present embodiment is related, comprise: catoptron backrest 1, catoptron 2, catoptron top adjustment part 3, catoptron left and right sides adjustment part 4 and set screw 5, described catoptron 2 is arranged in the catoptron backrest 1, catoptron top adjustment part 3 is fixed on the top of catoptron backrest 1, catoptron left and right sides adjustment part 4 is fixed on the left and right sides of catoptron backrest 1, is respectively equipped with set screw 5 on catoptron top adjustment part 3 and the catoptron left and right sides adjustment part 4.
During use, catoptron is placed in the catoptron backrest first, again catoptron top adjustment part, catoptron left and right sides adjustment part are fixed on the catoptron backrest, set screw is connected on catoptron top adjustment part and the catoptron left and right sides adjustment part, when adjusting the angle of catoptron such as need, adjust the position of set screw, then can realize the change of angle.
The above; it only is the better embodiment of the utility model; these embodiments all are based on the different implementations under the utility model general idea; and protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
