Description
Technical field
The utility model relates to a kind of adjustment structure, is specifically related to a kind of adjustment structure of optical projection system.
Background technology
The non-spherical reflector of reflective projection system front 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 the acrylic moulding, is then plated reflectance coating.The meeting that cannot avoid in the plastic rubber shaping process produces distortion, and that the piece surface profile requires is very high, is micron level substantially, accomplishes that this precision grade need to pay very high cost and differ and get a desired effect surely.Available technology adopting the left and right of catoptron and under three sides on the adjustment structure is set respectively, by 3 adjustment, determine a plane, but the position of every bit adjusts, only to change the integral body size on corresponding limit, and can not adjust local distortion.
Summary of the invention
Goal of the invention: the purpose of this utility model is in order to overcome deficiency of the prior art, provides a kind of simple in structure, can adjust local distortion, the novel adjustment structure of the reflective projection system reduced production costs.
Technical scheme: in order to solve the problems of the technologies described above, the novel adjustment structure of a kind of reflective projection system described in the utility model, it comprises fixed support, be provided with the screw mounting hole at described fixed support one end, be respectively equipped with the first screw hole and the second screw hole on the described support bracket fastened other end, be respectively equipped with the first screw rod and the second screw rod in described the first screw hole and the second screw hole, described the first screw rod and the second screw rod are flexibly connected with described the first screw hole and the second screw hole respectively.
Described the first screw rod is rotatable the connection with the first screw hole.
Described the second screw rod is rotatable the connection with the second screw hole.
Described fixed support lower end is fixedly connected with catoptron by screw.
Described the first screw rod all passes described catoptron with the second screw rod and is connected with described fixed support.
Described fixed support, the first screw rod and the second screw rod have three, and they are equipped with at the left end on described catoptron top, intermediate ends and right-hand member.
Positions are adjusted in the utility model three of many increases on catoptron, as push-pull configuration; Can effectively improve local distortion's situation of top by the push-pull configuration of top three points, this structure is exactly to utilize acrylic material that certain intensity is arranged and the characteristic that can be out of shape by external force, push-and-pull by external force, change surface profile, thereby reach the problem of improving picture local distortion.
Adjustment mode of the present utility model is summarized as follows: when both sides are fixed, when centre is pushed away, can make the distortion of picture intermediate projections reduce, reach ideal state, in like manner, if midway film when depression time can adopt the mode of drawing; When centre is fixed, when push-and-pull is carried out on both sides, can improve the local distortion in upper left and Liang Ge corner, upper right.
Beneficial effect: the utility model compared with prior art, its remarkable advantage is: each parts of the utility model are closely connected, compact conformation, adopt at 3 on catoptron top fixed support is set simultaneously, the adjustment structure that the first screw rod and the second screw rod form, can effectively improve local distortion's situation of top, so, when the precision of catoptron is poor, can adjust structure by employing, reach the effect of eliminating local distortion, production control cost well, in process of production, also reduced the accuracy requirement of mirror surface profile, this product structure is simple, serviceable life is longer, realistic request for utilization.

Fig. 2 is the partial enlarged drawing at A place in Fig. 1.
Wherein:
1, fixed support; 2, screw mounting hole; 3, the first screw hole; 4, the second screw hole; 5, the first screw rod; 6, the second screw rod; 7, screw; 8, catoptron
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As depicted in figs. 1 and 2, the novel adjustment structure of a kind of reflective projection system described in the utility model, it comprises fixed support 1, be provided with screw mounting hole 2 at described fixed support 1 one ends, be respectively equipped with the first screw hole 3 and the second screw hole 4 on the other end of described fixed support 1, be respectively equipped with the first screw rod 5 and the second screw rod 6 in described the first screw hole 3 and the second screw hole 4, described the first screw rod 5 and the second screw rod 6 are flexibly connected with described the first screw hole 3 and the second screw hole 4 respectively; Described the first screw rod 5 is rotatable the connection with the first screw hole 3; Described the second screw rod 6 is rotatable the connection with the second screw hole 4; Described fixed support 1 lower end is fixedly connected with catoptron 8 by screw 7; Described the first screw rod 5 all passes described catoptron 8 with the second screw rod 6 and is connected with described fixed support 1; Described fixed support 1, the 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 tops; 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 by the push-and-pull cooperation of three points, can effectively change the distortion situation of picture.Each parts of the utility model are closely connected, compact conformation, adopt on catoptron top at 3 the adjustment structure that fixed support, the first screw rod and the second screw rod form is set simultaneously, can effectively improve local distortion's situation of top, so, when the precision of catoptron is poor, can adjust structure by employing, reach the effect of eliminating local distortion, production control cost well, in process of production, also reduced the accuracy requirement of mirror surface profile, this product structure is simple, and serviceable life is longer, realistic request for utilization.
The utility model provides a kind of thinking and method; method and the approach of this technical scheme of specific implementation are a lot; the above is only preferred implementation of the present utility model; should be understood 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, in the present embodiment not clear and definite each ingredient all available prior art realized.
