Description
Technical field
The utility model relates to the fine-tuning digital optical display rear-projector's TV of a kind of large reflective mirror.
Background technology
The basic light path of digital optical display rear-projector's TV is: the light beam that the beam direction liquid crystal light valve of light emitted, liquid crystal light valve will form image information amplifies, and by speculum, is transmitted on the screen again.Reflection is divided into primary event and secondary reflection, in practice, the size of factor word light display rear projector TV is bigger, all be provided with a large reflective mirror, this speculum is made by glass, regulate light path when producing for convenience, usually fixing at least three root posts support big transmitting mirror on base, plane that each column top forms and screen form certain angle, because large reflective mirror is big and heavy, need fixedly secure, be nonadjustable after therefore conventional large reflective mirror installs and fixes, in order to regulate light path, as shown in Figure 1, be provided with ray machine 3 and small reflector 2, the rayed that ray machine 3 sends is on small reflector 3, small reflector 3 reflects light on the large reflective mirror 1 again, and large reflective mirror 1 is transmitted into light on the screen 4; The adjusting of this structure light path relies on the position of regulating small reflector or ray machine fully, but digital optical display rear-projector's TV volume is big, the manufacturing of each part has error unavoidably, also can produce error in the assembling process, there is the light path error equally in ray machine itself, all accumulations of error cause only depending in the actual production adjusting small reflector or ray machine position to be difficult to or can't cause correct projected position to the light path adjusting, bring very big difficulty to production.
Summary of the invention
The purpose of this utility model is exactly in order to overcome the above problems, and provides a kind of large reflective mirror fine-tuning digital optical display rear-projector's TV.
The utility model realizes that the above-mentioned purpose scheme is: digital optical display rear-projector's TV that a kind of large reflective mirror is fine-tuning, comprise base, large reflective mirror, the strutting piece and first fixture, also comprise second fixture, large reflective mirror, strutting piece, first fixture and second fixture all are positioned at the base top, first fixture, one end is fixed on the base, the other end and strutting piece lower end flexibly connect, second fixture, one end and base connect, the other end is fixed on the strutting piece lower end, second fixture is used to make strutting piece to rise or descend with respect to first fixture, and large reflective mirror is fixed on the strutting piece top.
Described strutting piece is at least not three root posts on same straight line.
Described column is a square column.
Described first fixture is a bearing, and column is n limit shape post (n＞4), and 3～n-1 bearing of each column correspondence, an end of each bearing flexibly connect with a side of the lower end of column respectively.
Bearing is the L template, on one side bearing is screwed on base, has via hole on the bearing another side, and via hole is a through hole, and via hole comprises that being used to finely tune the relative bearing of column rises or drop to the strip via hole that is fit to fastening bearing and column behind the height.
Described via hole also comprises the round via hole that is used to finely tune preceding fastening bearing of column height and column.
Have at least a strutting piece correspondence that second fixture is set.
Described second fixture comprises support plate and can drive the adjustment screw that support plate moves up and down, support plate is the L template, one side being fixed on the column lower end sidewall of support plate, the another side of support plate has through hole, adjustment screw is passed this through hole, and the bottom of adjustment screw and base upper surface connect.
Adopt the beneficial effect of above scheme:
Second fixture is set, make strutting piece to rise or to descend with respect to first fixture, when regulating small reflector and ray machine and still can't be adjusted to correct projected position to the light path of digital optical display rear-projector's TV, thereby can reach the purpose of regulating light path by the height of regulating strutting piece and then the angle of regulating between large reflective mirror and the screen, the utility model solved prior art digital optical display rear-projector's TV can't regulate large reflective mirror the position and and screen between the drawback of angle, improved productivity ratio, simple to operate, safe and reliable.
