Description

Manual angular position regulating device

Technical field

The utility model relates to position, a kind of angle regulating device, particularly relates to a kind of Manual angular position regulating device.

Background technique

Existing Manual angular position platform can provide low-angle rotation to regulate, and it mostly is double-layer structure, adopts adjustable swallow-tail way, uses worm gear pair to drive and handwheel locking; Can design in pairs, rotating center is same point after the stack, can carry out the adjustment of orthogonal double axle Concentric rotation.When being used for CCD or lanscape lens and object of observation being observed or accurately gathered two dimension or three-dimensional data information, often by using Manual angular position platform to adjust the angle of object of observation, by movement in a curve, adjust platform drive observation thing and move, reach adjusting platform and upper angular adjustment purpose of observing thing thereof.

But this regulative mode, with the Up-and-down of observing thing, move horizontally, there is following defective: 1, move horizontally because observing deposits yields, causing observing thing breaks away from from the visual field or departs from, solution is: must observe thing by all around translation adjustment, make its return, to the position of being convenient to observe; 2, because observing the deposits yields Up-and-down, cause focal length inaccurate, be again adjusting focal length again.Can make the image of object of observation get back among the visual field and keep the clear of image by adjustment repeatedly, repeatedly, this adjustment is many can not to be settled at one go, exist displacement and---adjust---again displacement---problem of adjusting again, therefore cause the observation inconvenient operation of finding a view, observed efficiency is not high.

The model utility content

The purpose of this utility model is exactly for present Manual angular position platform when being used for CCD or lanscape lens and object of observation being observed or accurately gathered two dimension or three-dimensional data information, when object of observation is carried out adjusting angle respectively on the orthogonal double axle, object of observation tends to depart from or break away from the problem of visual field of finding a view, and a kind of Manual angular position regulating device is provided.

To achieve these goals, the utility model has adopted following technological scheme:

A kind of Manual angular position regulating device, its structure comprise can place the arc slide of adjusting on the platform, is provided with the arc worm gear of working in coordination in the slide and with the first worm screw of knob; The upper end of arc worm gear is provided with major axis, and major axis points to the center of circle direction of arc, connects successively worm gear, connecting plate, U-shaped frame on the major axis; Arc worm gear upper end is connected with the second worm screw by the axle ear, and the worm gear on the second worm screw and the major axis is worked in coordination; The support on the opening end both sides of U-shaped frame is provided with clamping bar, and the clamping bar end in the U-shaped frame opening is provided with chuck, and the clamping bar between chuck and the U-shaped frame is provided with spring.

For can concise description for the purpose of the problem, below to Manual angular described in the utility model position regulating device all referred to as this device.

During use, this device is installed on the adjustment platform, U-shaped frame opening surface is to the operator, under the prerequisite of the CCD in observation device or lanscape lens invariant position, with object of observation facing up, aim at CCD in the observation device or the lanscape lens of observation device, and place the chuck middle part, clamp;

By the first worm screw with the pairing of arc worm gear that arranges on the arc slide is carried out clockwise direction or anticlockwise rotation adjustment, can make object of observation when the arc worm gear descends or rises, realize the clockwise or anticlockwise angular adjustment of U-shaped frame take two clamping bar center lines as axle; And in the situation of object of observation rising, fall minimum, realize the maximum adjustment to the object of observation angle.When being positioned at outside the center of circle of arc worm gear such as the chuck of U-shaped frame opening end when (greater than radius), when the arc worm gear is rising and the opening end of U-shaped frame and object of observation are camber line and descend, when the arc worm gear when descending and the opening end of U-shaped frame and object of observation are camber line and rise; When (less than radius), the motion of object of observation is with aforementioned opposite when being positioned at outside the center of circle of arc worm gear such as the chuck of U-shaped frame opening end; The distance that object of observation rises or descends along with the chuck of U-shaped frame opening end near the degree in the center of circle and more and more less, when the chuck of U-shaped frame opening end is positioned at the circle centre position of arc worm gear, about object of observation will not produce, move forward and backward, the rotation take two clamping bar center lines as axle is only arranged;

Carry out clockwise direction or anticlockwise rotation adjustment by the second worm screw that arc worm gear upper end is arranged, worm gear drives major axis, connecting plate and the rotation of U-shaped frame by pairing, make object of observation in the situation that does not produce any displacement, realize its adjustment in the angle of swing of chuck opening end take the major axis center line as axle.

Adopt the advantage of this device to be:

1, after object of observation is carried out the adjustment of position, angle, do not need the translation adjustment is carried out in the position of object of observation, the image of object of observation is remained among the visual field of observation device;

2, when object of observation being carried out the small angle adjustment, there is not the generation of obvious rising or decline situation in the object of observation, does not namely need the focal length of CCD or lanscape lens is adjusted, and the image of object of observation is still clear.

In sum, adopt the structure of this Manual angular position regulating device, realized when the angular adjustment of object of observation being carried out on orthogonal double axle, do not need to carry out repeatedly, about object of observation is carried out repeatedly, the position adjustment of front and back and rising, decline, the image that still can guarantee object of observation remains among the visual field and image is clear state, thereby improved observed efficiency, easy to use.
