[0003] To solve the above-mentioned problem, the present invention provides a retractable astronomical tripod, which is composed of a center column, a chassis, and a tripod sliding mechanism; the lower end of the center column is connected to the chassis; the tripod sliding mechanism is composed of a sliding plate and a tripod telescopic rod, the sliding plate is arranged in the center column, the tripod telescopic rod is connected to the sliding plate by a rotating shaft, the chassis is provided with a through hole corresponding to the tripod telescopic rod, and a support plate is provided at the lower end of the chassis in the direction corresponding to the tripod telescopic rod. The sliding plate can slide up and down in the center column, driving the tripod telescopic rod to extend or retract, and after the sliding plate slides to the lower end, the tripod telescopic rod is extended outward and fixed by the support plate. The tripod telescopic rod is provided with multiple rod sections, which are adjusted by rotating the fixing sleeve of each section. A connecting mechanism is provided at the upper end of the center column, and the connecting mechanism is used to connect the astronomical telescope.

[0004] Furthermore, a fixed shaft is positioned at the center of the center column. One end of the fixed shaft is connected to the top of the center column, and the other end passes through a through-hole in the center of the sliding disk and connects to the base. The sliding disk is connected to the fixed shaft via a linear bearing. The fixed shaft prevents the sliding disk from shifting within the center column. A protrusion is provided on the edge of the sliding disk, and a groove is provided on the inner wall of the center column to mate with the protrusion. The combination of the protrusion and groove prevents the sliding disk from rotating within the center column.

[0005] Furthermore, spring locating pins are provided at the upper and lower portions of the center column, and the spring locating pins pass through the center column and connect to pin holes provided on the sliding plate. When the sliding plate slides to the upper end of the center column, it is fixed by the spring locating pins at the upper end of the center column, and when the sliding plate slides to the lower end of the center column, it is fixed by the spring locating pins at the lower end of the center column.

[0006] Further, a tripod support mechanism is provided at the bottom of the chassis; the tripod support mechanism consists of a screw rod, a support block, a rotating nut and a locking nut. A locking nut is provided at the lower end of the screw rod, and the upper end passes through the rotating nut and the support block in sequence and then is connected to the chassis. When the tripod telescopic rod is unfolded outward, the rotating nut can be rotated to make the rotating nut move downward. Then, after the support block is rotated to the angle of supporting the tripod telescopic rod, the rotating nut is rotated in the reverse direction to make the rotating nut move upward to lock the support block. The support block and the support plate respectively fix the tripod telescopic rod from below and above. When the tripod telescopic rod needs to be retracted, first rotate the rotating nut to make the rotating nut move downward to loosen the support block, then rotate the angle of the support block to adjust the support block to the gap between the three tripod telescopic rods, and then adjust the angle of the tripod telescopic rod to be parallel to the central column and retract it into the central column.

[0007] The above technical solution of the present utility model has the following beneficial technical effects: By accommodating the tripod sliding mechanism in the central column, this tripod is convenient for storage and can also protect the tripod sliding mechanism through the central column. The product has a small volume, is easy to carry, and is convenient to operate. It saves the time for the user's preliminary preparation work and the trouble during transportation.
