Description

Universal ball type adjusting device for astronomical telescope

Technical Field

The utility model relates to an astronomical telescope technical field specifically is an universal ball formula adjusting device of astronomical telescope.

Background

Adjusting mechanical device of astronomical telescope: because of the rotation of the earth, all celestial bodies in the sky surround the rotation axis of the earth and do the diurnal movement of east-rising west-falling along the declination circle on the celestial sphere, therefore, the celestial body aligned with the telescope can quickly run out of the field of view, the telescope needs to constantly adjust the direction to be always aligned with the target, and the telescope is required to be arranged on a device which can freely adjust the direction at will, and the device has two types: a horizon and an equatorial.

The adjusting device of the horizon type astronomical telescope is the simplest structural form at present in a telescope device, and comprises two mutually vertical rotating shafts, one of which is positioned in a horizontal plane and called as a horizontal shaft (namely a height shaft), and the height of the telescope can be adjusted within a range of +/-90 degrees; the other is in the plumb direction, called a vertical axis (namely an azimuth axis), and the telescope can be adjusted in azimuth within the range of 0-360 degrees. The tripod for cameras, movie cameras and video cameras which we usually see is such a floor-mounted device. The telescope column is independently rotated up and down or horizontally around two axes. The disadvantage is that the horizontal and vertical rotation directions are not consistent with the direction of the celestial body rotating in the same day, so the telescope must move with two axes when tracking the celestial body, and the operation is troublesome.

The equatorial device also has two axes perpendicular to each other, one axis being parallel to the earth's rotation axis, i.e. its angle of intersection with the ground plane is equal to the local geographical latitude, this axis being called the right ascension axis (or polar axis), which is the tracking axis. Its advantages are automatic tracking, complex structure and high cost. The operation is also complicated for the novice.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model discloses an adopt following technical scheme: the universal ball type adjusting device for the astronomical telescope is characterized in that: comprises an astronomical telescope, a universal ball seat, a dovetail groove plate and a foot rest; the top of the universal ball seat is provided with an opening, the universal ball is rotatably arranged in the universal ball seat, the top exposed part is fixedly connected with the dovetail groove plate, and the diameter of the opening of the universal ball seat is smaller than that of the universal ball; the bottom of the outer side of the astronomical telescope is provided with a dovetail plate, and the astronomical telescope is fixedly arranged on the dovetail plate through the dovetail plate; a damping pad pressing plate is arranged at the bottom of the universal ball seat, and a damping pad is arranged between the damping pad pressing plate and the universal ball; a foot rest holder is fixedly arranged on the foot rest, and the top of the foot rest holder is fixedly connected with the universal ball seat; the tripod head center is equipped with the screw thread through-hole, threaded connection has the locking hand wheel in the screw thread through-hole, locking hand wheel top and damping pad clamp plate bottom butt.

Further, the dovetail groove plate and the universal ball are fixedly connected through screws.

Furthermore, the top of the tripod head is fixedly connected with the universal ball seat through screws.

Has the advantages that: compared with the prior art, the utility model discloses an adjustment of astronomical telescope observation position is realized to the universal rotation of bulb formula of universal ball, and is easy and simple to handle. The device has simple structure and low cost.

In the figure, 1, an astronomical telescope; 2. a dovetail groove plate; 3. a universal ball; 4. a universal ball seat; 5. a tripod head; 6. a damping pad; 7. a damping pad pressing plate; 8. locking a hand wheel; 9. a dovetail plate; 10. a foot rest.

Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully with reference to the accompanying drawings. The present invention may be embodied in many different forms and is not limited to the embodiments described in the text. Rather, the embodiments are provided so that this disclosure will be thorough and complete.

As shown in the attached drawings, the universal ball type adjusting device for the astronomical telescope comprises an astronomical telescope 1, a universal ball 3, a universal ball seat 4, a dovetail groove plate 2 and a foot rest 10; the top of the universal ball seat 4 is provided with an opening, the universal ball 3 is arranged in the universal ball seat 4 and can rotate freely, the top exposed part and the dovetail groove plate 2 are fixedly connected through screws or other modes, and the diameter of the opening of the universal ball seat 4 is smaller than that of the universal ball 3 so as to limit the universal ball 3 to be separated from the universal ball seat 4; the bottom of the outer side of the astronomical telescope 1 is provided with a dovetail plate 9, and the astronomical telescope 1 is fixedly arranged on the dovetail groove plate 2 through the dovetail plate 9; a damping pad pressing plate 7 is arranged at the bottom of the universal ball seat 4, and a damping pad 6 is arranged between the damping pad pressing plate 7 and the universal ball 3; a foot stand tripod head 5 is fixedly arranged on the foot stand 10, and the top of the foot stand tripod head 5 is fixedly connected with the universal ball seat 4 through screws or other modes; the foot rest tripod head 5 center is equipped with the screw thread through-hole, threaded connection has locking hand wheel 8 in the screw thread through-hole, 8 tops of locking hand wheel and damping pad clamp plate 7 bottom butt, and the screw thread in the middle of 8 accessible foot rest tripod heads of locking hand wheel moves up and down to the position of adjustment astronomical telescope 1 is observed.

The working principle is as follows: the locking hand wheel 8 is rotated to enable the locking hand wheel to move upwards in the tripod head 5, the damping pad pressing plate 7 and the damping pad 6 are pushed to move upwards, the gap between the damping pad 6 and the universal ball 3 is reduced, the friction force between the damping pad 6 and the universal ball 3 is increased, and therefore the purpose of limiting the rotation of the universal ball 3 is achieved, and the astronomical telescope 1 can be observed at the required position at the moment. When the locking hand wheel 8 moves downwards, the gap between the damping pad 6 and the universal ball 3 is increased, the friction force between the damping pad and the universal ball 3 is reduced, and the universal ball 3 can rotate randomly at the moment, so that the astronomical telescope 1 can be adjusted to the direction needing to be observed. Namely, when the astronomical telescope 1 needs to be adjusted, the locking hand wheel 4 is loosened to adjust; after the adjustment is finished, the locking hand wheel 4 is locked, and then the astronomical telescope 1 is observed.

In the above embodiments, all functions may be implemented, or a part of the functions may be implemented as necessary.

It should be noted that the various features described in the above embodiments may be combined in any suitable manner without departing from the scope of the invention. In order to avoid unnecessary repetition, the present invention does not separately describe various possible combinations.
