Abstract
The utility model discloses an optic regulating frame which comprises a frame seat (1), wherein the frame seat (1) provided with concave table holes (10) and internal thread holes (8) is connected with a lens frame (2) provided with concave table holes (5) in the way of a movable fit by elastic connecting pieces and screws (9); the concave table holes (5, 10), the internal thread holes (8), the elastic connecting pieces and the screws (9) are two; a central angle between the two internal thread holes (8) is a right angle; especially a steel ball (3) is arranged between the frame seat (1) and the lens frame (2); the steel ball (3), the elastic connecting pieces and the screws (9) are arranged in a straight line; the elastic connecting piece is formed by the method that both ends of a screw bolt (4) penetrating through the concave table holes (5, 10) are penetrated and hung with an elastic disk (6); the screw bolt (4) is formed by the method that both ends of an internal thread rod are provided with screws (41). The utility model has the advantages of agile regulation, firmness, no mutual interference between regulation in two orientations, no need of secondary fastening after the regulation, simple structure, convenient and reliable use and strong practicality, and can be widely used for the regulation of various optical paths.
Description
Technical field
The utility model relates to a kind of optical adjustment device, especially optical adjusting frame.
Background technology
At present, in Experiments of Optics and laser application, people often use the optical element orientation adjusting device in order to solve the adjustment problem of its light path, are adopted in the laser radar as the applicant.It is made of with spring, set screw and clamp-screw on the semi-circumference of footpath stand, mirror holder and placing that it is connected, and wherein, the central angle between three set screw is the right angle, and all the screw on stand contacts mutually with mirror holder; Clamp-screw also is three, and the central angle between itself and set screw is 45 degree, and it is fixed all by through hole on the stand and screw on the mirror holder it to be drawn mutually; Five springs are distributed between set screw and clamp-screw, and its two ends are hooked on respectively in the through hole of stand and mirror holder.During adjustment, adjust light path, be locked with clamp-screw again by the rotation set screw.But this device exists weak point, at first, three set screw that on semi-circumference, are provided with, wherein every is a point of adjustment, is again the strong point, when regulating certain orientation, easily make other orientation that trace also takes place and change, cause the adjustment of light path very difficult; Secondly, spring and set screw and mirror holder are and contact, and spring wherein very easily absorbs each side's external force with the twist distortion of self, and set screw contacts for sliding again, so though it regulates sensitively, unstable, easily make mirror holder in the micro-variation of multi-faceted generation; Once more, when the mirror holder of adjusting with the clamp-screw locking, also can destroy by three set screw and be slided the balanced surface that pushes up, promptly must regulate, tighten up and begin successfully in repeated multiple times ground; At last, owing to be to connect by spring, mirror holder and its own wt of going up fixing eyeglass cause easily that also the orientation of mirror holder trace takes place changes, and be particularly evident during big or attitude change when deadweight, makes its anti-vibration ability.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of optical adjusting frame for overcoming weak point of the prior art.
The technical scheme that is adopted comprises that the stand that is provided with concave station hole and internal thread hole is connected with the mirror holder that is equipped with the concave station hole with screw movingly through Flexible Connector, said concave station hole, internal thread hole, Flexible Connector and screw are two, central angle between said two internal thread holes is the right angle, be equipped with steel ball between particularly said stand and mirror holder, said steel ball, Flexible Connector and screw linearly are provided with, and said Flexible Connector is that the two ends of running through the bolt in concave station hole are worn and hung with the elasticity video disc.
As the further improvement of technical scheme, the contact position of described stand that is connected with steel ball and mirror holder is a spherical pit; Described steel ball is positioned at the center of stand and mirror holder; Described bolt is that the two ends of internal thread bar are equipped with screw; Described screw is a ball screw.
Beneficial effect with respect to prior art is, one, the existence of steel ball, and itself and Flexible Connector, screw linearly be provided with, both made unique together support point had been arranged between stand and mirror holder, make mirror holder only can do the orientation adjusting of one dimension again along this straight line, and the interference when not influencing other orientation or not regulated by other orientation, regulate an orientation no matter promptly be, still two orientation are regulated simultaneously, all only can only have an effect, accomplish that the adjusting in two orientation is not disturbed mutually, be easy to adjust successfully with settling at one go the orientation that is conditioned; Its two, the elasticity video disc in the Flexible Connector is anchor ring with stand and mirror holder and contacts, and the elasticity video disc can not be distorted after being extruded, it is sensitive and firm that it is regulated; Its three, big, the distribution uniform of the active area of elasticity video disc power does not need capable tightening up after therefore having adjusted again, the ability that its anti-environmental vibration, variation of ambient temperature influence is strong; Its four, simple in structure, easy to use, reliable, practical.
Description of drawings
Below in conjunction with accompanying drawing optimal way of the present utility model is described in further detail.
Fig. 1 is a kind of basic structure front view of the present utility model;
Fig. 2 is the partial sectional view along the A-A line shown in Figure 1.
Embodiment
Referring to Fig. 1, Fig. 2, it is the right angle that discoidal mirror holder 2 is provided with two central angles that are positioned at 5 in 5, the two concave station holes, concave station hole on the circumference of footpath; Be equipped with two the concave station holes 10 corresponding and the internal thread hole 8 of two inward turning ball screws 9 on the stand 1 with the concave station hole 5 on the mirror holder 2; The center of mirror holder 2 and stand 1 is pit, is equipped with steel ball 3 therebetween; Two are rotary with the bolt 4 that the internal thread bar of screw 41 constitutes by two ends and run through two pairs of concave station holes (5 respectively, 10), the two ends of every bolt 4 are worn respectively and are hung with five elasticity video discs 6 and a pad 7, and screw 41 is pressed in elasticity video disc 6 and pad 7 on the hole platform in concave station hole (5,10); Steel ball 3, bolt 4 and ball screw 9 linearly are provided with.
During use, place the utility model that is fixed with optical element on the mirror holder 2 on the light path after, only need regulate ball screw 9 and can adjust required light path soon.
