Abstract
The invention relates to a novel adjusting structure of a reflective projection system. The novel adjusting structure comprises a fixing support. A screw installation hole is formed in one end of the fixing support. A first screw rod hole and a second screw rod hole are formed in the other end of the fixing support. A first screw rod and a second screw rod are arranged inside the first screw rod hole and the second screw rod hole respectively. The first screw rod and the second screw rod are movably connected with the first screw rod hole and the second screw rod hole respectively. The novel adjusting structure is simple in structure and capable of adjusting local distortion, and the production cost is reduced.
Description
Technical field
The present invention relates to a kind of adjust structure, be specifically related to a kind of adjust structure of optical projection system.
Background technology
Non-spherical reflector before reflective projection system mainly contains two effects, and one, the distortion of control interface, two, participate in the imaging of whole imaging system.This catoptron is the very important part of whole system, so adopt aspheric surface profile, precision prescribed is high.The processing technology adopted is that acrylic is shaping, then carries out plating reflectance coating.The meeting cannot avoided in plastic rubber shaping process produces distortion, and piece surface profile requires very high, is micron level substantially, accomplishes that this precision grade needs to pay very high cost and differs and get a desired effect surely.Adopt in prior art the left and right of catoptron and under three sides on adjust structure is set respectively, by 3 adjustment, determine a plane, but the position of every bit adjustment, only to change the overall size on corresponding limit, and can not local distortion be adjusted.
Summary of the invention
Goal of the invention: the object of the invention is to overcome deficiency of the prior art, provides a kind of structure simple, can adjust local distortion, reduce the novel adjust structure of the reflective projection system of production cost.
Technical scheme: in order to solve the problems of the technologies described above, the novel adjust structure of a kind of reflective projection system of the present invention, it comprises fixed support, screw mounting hole is provided with in described fixed support one end, the described support bracket fastened other end is respectively equipped with the first screw hole and the second screw hole, in described first screw hole and the second screw hole, be respectively equipped with the first screw rod and the second screw rod, described first screw rod and the second screw rod are flexibly connected with described first screw hole and the second screw hole respectively.
Described first screw rod and the first screw hole are rotatable connection.
Described second screw rod and the second screw hole are rotatable connection.
Described fixed support lower end is fixedly connected with catoptron by screw.
Described first screw rod and the second screw rod all pass described catoptron and are connected with described fixed support.
Described fixed support, the first screw rod and the second screw rod have three, and they are equipped with left end, intermediate ends and right-hand member on described catoptron top.
The present invention is the many increases in face three adjustment position on the mirror, as push-pull configuration; Local distortion's situation of top effectively can be improved by the push-pull configuration of three points above, this structure is exactly the characteristic utilizing acrylic material to have certain intensity and can be out of shape by external force, by the push-and-pull of external force, change surface profile, thus reach the problem improving picture local distortion.
Adjustment mode of the present invention is summarized as follows: when both sides are fixed, when centre pushes away, and the distortion of picture intermediate projections can be made to reduce, reach ideal state, in like manner, if during midway film during depression, can adopt the mode of drawing; When centre is fixed, when push-and-pull is carried out on both sides, the local distortion in upper left and upper right two corners can be improved.
Beneficial effect: the present invention compared with prior art, its remarkable advantage is: each member in tight of the present invention is connected, compact conformation, portion adopts arrange fixed support at 3 simultaneously on the mirror, the adjust structure of the first screw rod and the second screw rod composition, effectively can improve local distortion's situation of top, so, when the precision of catoptron is poor, can by adopting adjust structure, reach the effect eliminating local distortion, can production control cost well, in process of production, also reduce the accuracy requirement of mirror surface profile, this product structure is simple, serviceable life is longer, realistic request for utilization.

Embodiment
Below in conjunction with drawings and Examples, the present invention is further illustrated.
As depicted in figs. 1 and 2, the novel adjust structure of a kind of reflective projection system of the present invention, it comprises fixed support 1, screw mounting hole 2 is provided with in described fixed support 1 one end, the other end of described fixed support 1 is respectively equipped with the first screw hole 3 and the second screw hole 4, in described first screw hole 3 and the second screw hole 4, be respectively equipped with the first screw rod 5 and the second screw rod 6, described first screw rod 5 and the second screw rod 6 are flexibly connected with described first screw hole 3 and the second screw hole 4 respectively; Described first screw rod 5 is connected for rotatable with the first screw hole 3; Described second screw rod 6 is connected for rotatable with the second screw hole 4; Described fixed support 1 lower end is fixedly connected with catoptron 8 by screw 7; Described first screw rod 5 and the second screw rod 6 all pass described catoptron 8 and are connected with described fixed support 1; Described fixed support 1, first screw rod 5 and the second screw rod 6 have three, and they are equipped with left end, intermediate ends and right-hand member on described catoptron 8 top; When the first screw rod 5 rotates along the direction of arrow in Fig. 2, catoptron will advance to draw direction, now picture can become large, when the second screw rod 6 rotates along the direction of arrow in Fig. 2, catoptron will advance to push away direction, now picture can diminish, and is coordinated, effectively can change the distortion situation of picture by the push-and-pull of three points.The each member in tight of the present invention is connected, compact conformation, portion adopts 3 adjust structure simultaneously arranging fixed support, the first screw rod and the second screw rod composition on the mirror, effectively can improve local distortion's situation of top, so, when the precision of catoptron is poor, can by adopting adjust structure, reach and eliminate the effect of local distortion, can production control cost well, in process of production, also reduce the accuracy requirement of mirror surface profile, this product structure is simple, and serviceable life is longer, realistic request for utilization.
The invention provides a kind of thinking and method; the method and access of this technical scheme of specific implementation is a lot; the above is only the preferred embodiment of the present invention; should be understood that; for those skilled in the art, under the premise without departing from the principles of the invention, some improvements and modifications can also be made; these improvements and modifications also should be considered as protection scope of the present invention, and all available prior art of each ingredient not clear and definite in the present embodiment is realized.
